Nano-Diamino-Tetrac (NDAT) Enhances Resveratrol-Induced Antiproliferation by Action on the RRM2 Pathway in Colorectal Cancers

Abstract

Cancer resistance to chemotherapeutic agents is a major issue in the management of cancer patients. Overexpression of the ribonucleotide reductase regulatory subunit M2 (RRM2) has been associated with aggressive cancer behavior and chemoresistance. Nano-diamino-tetrac (NDAT) is a nanoparticulate derivative of tetraiodothyroacetic acid (tetrac), which exerts anticancer properties via several mechanisms and downregulates RRM2 gene expression in cancer cells. Resveratrol is a stilbenoid phytoalexin which binds to a specific site on the cell surface integrin αvβ3 to trigger cancer cell death via nuclear translocation of COX-2. Here we report that resveratrol paradoxically activates RRM2 gene expression and protein translation in colon cancer cells. This unanticipated effect inhibits resveratrol-induced COX-2 nuclear accumulation. RRM2 downregulation, whether achieved by RNA interference or treatment with NDAT, enhanced resveratrol-induced COX-2 gene expression and nuclear uptake which is essential to integrin αvβ3-mediated-resveratrol-induced antiproliferation in cancer cells. Elsewhere, NDAT downregulated resveratrol-induced RRM2 expression in vivo but potentiated the anticancer effect of the stilbene. These findings suggest that RRM2 appears as a cancer cell defense mechanism which can hinder the anticancer effect of the stilbene via the integrin αvβ3 axis. Furthermore, the antagonistic effect of RRM2 against resveratrol is counteracted by the administration of NDAT.

Effect of oral appliance on circulating leukocyte telomere length and SIRT1 in obstructive sleep apnea

Abstract

Objectives

The increased cardiovascular risk seen in patients with obstructive sleep apnea (OSA) may be due to combination of oxidative stress, systemic inflammation and damage to leukocyte telomere length (LTL) seen with aging. Another molecule, Sirtuin 1 (SIRT1), a histone/protein deacetylase, regulates endothelial nitric oxide synthase and is involved in different aspects of cardiovascular disease, aging and stress resistance. The aim of this study was to evaluate the effects of mandibular advancement device (MAD) on the circulating LTL and SIRT1 protein level in peripheral blood mononuclear cells (PBMCs) in patients with OSA.

Materials and methods

Forty patients with moderately severe to severe OSA who desired MAD and 20 healthy controls were prospectively enrolled. The LTL was measured by quantitative polymerase chain reaction while SIRT1 protein levels in PBMC was assessed using a Sirtuin 1 ELISA Kit. All study subjects underwent baseline sleep study, with OSA patients having repeat testing at 3 months after MAD.

Results

Compared to healthy subjects, patients with OSA at baseline had lower LTL and SIRT1 protein levels in PBMC. After 3 months of MAD, 24 OSA patients, designated as MAD responders, median (range) LTL increased from (0.556 [0.393–0.748]) to (0.708 [0.533–0.893]) and SIRT1 protein levels in PBMC increased from 0.58 ± 0.23 pg/μg of total protein to 0.95 ± 0.26 pg/μg of total protein. For the 16 MAD unresponsive patients, LTL and SIRT1 protein levels remained low.

Conclusions

Successful treatment of OSA with MAD can restore LTL and SIRT1 protein levels in PBMC.

Clinical relevance

LTL and SIRT1 protein levels in PBMC can be improved following effective treatment of OSA using MAD.

Survival Analysis and Interpretation of Time-to-Event Data: The Tortoise and the Hare

Survival analysis, or more generally, time-to-event analysis, refers to a set of methods for analyzing the length of time until the occurrence of a well-defined end point of interest. A unique feature of survival data is that typically not all patients experience the event (eg, death) by the end of the observation period, so the actual survival times for some patients are unknown. This phenomenon, referred to as censoring, must be accounted for in the analysis to allow for valid inferences. Moreover, survival times are usually skewed, limiting the usefulness of analysis methods that assume a normal data distribution. As part of the ongoing series in Anesthesia & Analgesia, this tutorial reviews statistical methods for the appropriate analysis of time-to-event data, including nonparametric and semiparametric methods—specifically the Kaplan-Meier estimator, log-rank test, and Cox proportional hazards model. These methods are by far the most commonly used techniques for such data in medical literature. Illustrative examples from studies published in Anesthesia & Analgesia demonstrate how these techniques are used in practice. Full parametric models and models to deal with special circumstances, such as recurrent events models, competing risks models, and frailty models, are briefly discussed.

Visual and Positional Modulation of Pendular Seesaw Nystagmus: Implications for the Mechanism

Background: The mechanisms of pendular seesaw nystagmus (SSN) remain unknown. Methods: We evaluated modulation of pendular SSN by removal of visual fixation, convergence, and positional changes in 2 patients, one with bitemporal hemianopia due to a traumatic damage of the optic chiasm and the other with platybasia compressing the medulla and lower cerebellum. Results: In both patients, the pendular SSN markedly decreased or disappeared with convergence, without visual fixation in darkness, during static head tilt toward each shoulder while sitting and while supine. Conclusions: The similar patterns of nystagmus modulation observed in our patients with a different etiology indicate a common role of both visual and otolithic inputs in generating pendular SSN.

Anaerobic end-products and mitochondrial parameters as physiological biomarkers to assess the impact of urban pollutants on a key bioturbator

Abstract

The impact of long-term exposure (6 months) to highly or slightly polluted sediments on the energy metabolism of an ecosystem engineer (the oligochaete Limnodrilus hoffmeisteri) was investigated in laboratory conditions. We evaluated some mitochondrial parameters (respiratory chain activity and ATP production rate) and the accumulation of anaerobic end-products (lactate, alanine, succinate, and propionate). The sediments were collected from stormwater infiltration basins and presented high levels of heavy metals and polycyclic aromatic hydrocarbons (PAHs). These compounds had been drained by the runoff water on impervious surfaces of urban areas during rainfall events. A decrease in the activity of the mitochondrial electron transport chain was observed in worms exposed to the most polluted sediment. Urban contaminants disrupted both aerobic metabolism and mitochondrial functioning, forcing organisms to shift from aerobic to anaerobic metabolism (which is characteristic of a situation of functional hypoxia). Although L. hoffmeisteri is very tolerant to urban pollutants, long-term exposure to high concentrations can cause disruption in mitochondrial activity and therefore energy production. Finally, this study demonstrated that anaerobic end-products could be used as biomarkers to evaluate the impact of a mixture of urban pollutants on invertebrates.

Use of various biomarkers to explore the effects of GSM and GSM-like radiations on flowering plants

Abstract

Since last decade, GSM (Global System for Mobile Communication) technology has evidently revolutionized our digital world. It uses electromagnetic frequency radiations (EMFr), ranging 850–1900 MHz, and is being composed of three main units (i.e., mobile station, access and core networks). GSM technology has significant impact on our daily life as revealed by increased number of mobile users in the world over. The main goal of the present review is to critically revisit the available literature regarding the responses of various flowering plant species towards GSM and GSM-like radiations using physiological, biochemical, molecular and cytological markers using in vitro approaches. Different monocots (tomato, onion, wheat and maize etc.) and dicots (pulses, mustard and flax) have been studied using both GSM mobile phone and GSM simulators. Different studies revealed overall reductions in germination, root-shoot lengths, dry weight, in both dose and time-dependent manners. However, there could be found incline in various parameters at biochemical and molecular levels. Furthermore, there could be found disturbances at cytological levels upon exposure of roots of onion to EMFr radiations. The overall literature review shows the negative effects of GSM and GSM-like radiations on targeted plant species. In order to alleviate the stressful effects of EMFr radiations on plants, in vivo studies need to be done using various cost-effective approaches such as use of biochar and various organic amendments.

Salivary adiponectin, but not adenosine deaminase, correlates with clinical signs in women with Sjögren’s syndrome: a pilot study

Abstract

Objectives

To evaluate salivary adiponectin and adenosine deaminase (ADA) in women suffering from Sjögren's syndrome (SS).

Methods

Salivary adiponectin and ADA were measured in patients with SS (n = 17) and compared to their values in healthy controls (n = 13) and patients suffering from drug-induced xerostomia (non-SS sicca group; n = 19). A clinical history was made for each patient, patients were examined clinically, and xerostomia inventory (XI) was performed.

Results

Salivary adiponectin corrected by total protein was higher in patients with SS than in healthy individuals (P < 0.05) or patients with non-SS sicca (P < 0.01) and correlated with XI (r = 0.555; P < 0.05). Salivary ADA was higher in patients with SS and non-SS sicca compared to controls (P < 0.05 in both cases).

Conclusion

The results of the present study indicate that adiponectin and ADA are increased in the saliva of patients with SS.

Clinical relevance

Salivary adiponectin corrected by total protein can be a potential biomarker of SS.

Abstract
History A 31-year-old woman with a history of bilateral orthotopic lung transplantation performed 10 months earlier for cystic fibrosis presented for a routine follow-up appointment, with her chief symptom being a cough. The cough started approximately 1 month prior to this appointment and was minimally productive of clear to yellow phlegm. In addition to her cough, she reported increased sinus congestion and a sensation of "something in her upper chest." She denied shortness of breath, wheezing, hemoptysis, or cigarette smoking. Review of systems was negative for fever, chills, or night sweats. At physical examination, the patient was afebrile, borderline tachycardic (heart rate, 99 beats per minute), and mildly hypertensive (blood pressure, 138/99 mm Hg). Oxygen saturation was 96% on room air. Laboratory evaluation revealed a white blood cell count of 3.5 × 109/L (normal range, 3.2-9.8 × 109/L). Pulmonary function testing was notable for a newly decreased ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) of 64% (2.0 and 3.4 L, respectively) (normal FEV1-to-FVC ratio, 80%), suggesting an obstructive lung process. One month prior to presentation, the patient's sputum cultures grew Pseudomonas and methicillin-resistant Staphylococcus aureus. The patient showed no evidence of active infection at the time of bronchoscopy. Thus, the bacteria were favored to reflect colonization, and antibiotic therapy was not administered at that time. The patient was taking an immunosuppression regimen of mycophenalate mofetil (CellCept; Genentech, San Francisco, Calif) (1 g twice daily), prednisone (10 mg daily), and tacrolimus (Prograf; Astellas Pharma US, Northbrook, Ill) (goal therapeutic range, 12-14 ng/mL). The patient was sent for posteroanterior and lateral chest radiography followed by chest CT ( Figs 1 - 3 ) and fluorine 18 fluorodeoxyglucose PET/CT ( Fig 4 ).

Diesel engine emission analysis using fuel from diverse emulsification methods

Abstract

The focus of this work is to investigate the emission characteristics of a stationary diesel engine while utilizing an emulsion fuel from a novel preparation process. The emulsion preparation was performed in real time without using any surfactant. Instead of mechanically breaking the water down into droplets, the water is delivered thermally, by changing its phase from gas to liquid. Steam is used in this proposed process, where it will be converted into suspended water droplets once it meets colder diesel. The product is called steam-generated water-in-diesel emulsion fuel (S/D). The method is expected to reduce the moving components of a previous surfactant-less system; therefore, reducing costs and increasing the system reliability. The emission characteristics of S/D were compared with EURO 2 diesel (D2), and a conventional emulsion denoted as E10. E10 was prepared using 10% water (volumetric) and SPAN80 as a surfactant. The emission characterizations were carried out based on the exhaust gas of a single cylinder naturally aspirated CI engine fueled with D2, S/D, and E10. Compared to D2, both emulsions significantly reduced the emissions of nitrogen oxides (NOx) (E10 max ↓58.0%, S/D max ↓40.0%) and particulate matter (PM) (E10 max ↓20.0%, S/D max ↓57.0%).

Diagnostic performance of 18 F-PSMA-1007 PET/CT in patients with biochemical recurrent prostate cancer

Abstract

Purpose

The introduction of ligands targeting prostate-specific membrane antigen (PSMA), especially ⁶⁸Ga-PSMA-11, has changed the management of patients with prostate cancer (PCa). ¹⁸F-Labelled ligands can be produced in larger amounts and therefore can improve availability for a larger group of patients. The aim of this study was to evaluate the diagnostic performance of the recently introduced ¹⁸F-PSMA-1007 in patients with recurrent PCa.

Methods

This retrospective analysis included 100 consecutive patients with biochemical relapse (mean age 68.75 ± 7.6 years) referred for PSMA PET/CT. Whole-body PET/CT imaging (from the lower limbs to the skull) was performed in all patients 120 min after injection of 338 ± 44.31 MBq ¹⁸F-PSMA-1007. Prostatectomy, radiation beam therapy of the prostate bed and androgen-deprivation therapy had been performed in 92%, 45% and 27% of the patients, respectively. Radiation beam therapy of the prostate bed had been performed in addition to surgery in 38 patients (38%) and 10 patients (10%) had received all three therapy modalities. The probability of a ¹⁸F-PSMA-1007 PET/CT scan suggestive of pathology was compared with the Gleason score (GS) and PSA level.

Results

Of the 100 patients, 95 (95%) showed at least one pathological finding on ¹⁸F-PSMA-1007 PET/CT. The overall median PSA level was 1.34 ng/ml (range 0,04–41.3 ng/ml). The rates of pathological scans were 86%, 89%, 100% and 100% among patients with PSA levels ≤0.5, 0.51–1.0, 1.1–2.0 and > 2.0 ng/ml, respectively. The median GS was 7 (range 5–10). The majority of patients (70) with a GS available had a score in the range 7–9. The rate of pathological scans in these patients was 93% (65/70). The median SUV_max values of the pathological findings were 10.25, 14.32, 13.16 and 28.87 in patients with PSA levels ≤0.5, 0.51–1.0, 1.1–2.0 and >2.0 ng/ml, respectively. The median SUV_max in patients with a PSA level of >2.0 ng/ml was significantly higher than in all other PSA groups.

Conclusion

¹⁸F-PSMA-1007 PET/CT can detect recurrent PCa in a high percentage of patients with biochemical relapse. The probability of a pathological ¹⁸F-PSMA-1007 PET/CT scan seems to be high even in patients with a low PSA level ≤0.5 ng/ml, and this may have a significant impact on the management of this relevant group of patients.

Robustness of eco-industrial symbiosis network: a case study of China

Abstract

As a complex network, eco-industrial symbiosis network is featured with complexity, openness, and non-linearity. A methodology is proposed to analyze and optimize the eco-industrial symbiosis network from the perspective of complex network theory. Structural robustness index and performance robustness index are established as the analysis model. Consequently, a robust method is developed to optimize the eco-industrial symbiosis network system based on the percolation theory. A conceptual framework is put forward to improve the robustness of eco-industrial symbiosis network system by introducing the "spare core" enterprise which is validated by quantitative analysis. The empirical results show that the robustness of eco-industrial symbiosis network varies under both random failure and intentional disturbance scenarios. However, eco-industrial symbiosis network system has strong self-regulation capability as long as the core enterprise is still in operation. It is recommended that supplementary chain could be added to those enterprises with lower network node connectivity to form "spare core" enterprise. This can not only effectively reduce the dependence of other enterprises on core enterprises, but also further improve the robustness of eco-industrial symbiosis network. This methodology is practically validated by a case analysis of eco-industrial park in China. The findings provide useful inputs to the design and operation of eco-industrial parks.

In silico study of Moxifloxacin derivatives with possible antibacterial activity against a resistant form of DNA gyrase from Porphyromonas gingivalis

Publication date: Available online 19 July 2018

Source: Archives of Oral Biology

Author(s): Cristian Rocha-Roa, Rodrigo Cossio-Pérez, Diego Molina, Jorge Patiño, Néstor Cardona

Abstract

We performed a homology modeling of the structure of a non-mutated and mutated Ser83→Phe DNA gyrase of Porphyromonas gingivalis. The model presented structural features conserved in type II topoisomerase proteins. We designed and evaluated in silico structural modifications to the core of Moxifloxacin by molecular docking, predicted toxicity and steered molecular dynamics simulations (SMD). Our results suggest that 8D derivative of Moxifloxacin could present a strong inhibitory activity in Porphyromonas gingivalis bacteria that exhibits resistance to some conventional fluoroquinolone drugs. Also, our results suggest that hydrophobic radicals in the hydroxyl group at position 3 of the quinolone core would increase the antibacterial activity of the compound when a reported mutation Ser83→Phe is present in the DNA gyrase protein. In addition, new candidates that could have a higher antibacterial activity compared to Moxifloxacin in non-resistant bacteria are proposed.

Arsenic removal from water by metal-organic framework MIL-88A microrods

Abstract

Fe-based metal-organic framework MIL-88A microrods were synthesized by hydrothermal method, which were used to adsorb As(V) in water for the first time. The experimental results indicated that MIL-88A has a very fast adsorption rate towards arsenic in water. The kinetic and isothermal data for arsenic removal were better fitted to the pseudo-second-order kinetic model and Langmuir model, respectively, implying a chemical and monolayer adsorption for As(V) on MIL-88A microrods. Two rate-controlling processes during adsorption were revealed by the intraparticle diffusion model. The maximum adsorption capacity of MIL-88A reached 145 mg g⁻¹, higher than those of Fe-based MIL adsorbents reported previously, which probably originates from its unique microstructure with abundant OH⁻ groups and an unusual large swelling towards water. These show that Fe-based MIL-88A is a good candidate for arsenic removal.

Source: American Journal of Otolaryngology

Author(s): Shane Griffith, Robert Archbold, Stephen Schell

Abstract

Purpose

To investigate the correlation between internet search activity and epistaxis-related Emergency Department visits.

Materials and methods

Data from Google Trends were obtained (www.google.com/trends) for the search term "nosebleed" in Erie County, Pennsylvania during a five-year period. All epistaxis-related CPT code events were obtained from one hospital in this county during the same period. Google total counts were cross tabulated with the following month's ED visits. Graphical analysis and correlation were used to assess the relationship between ED visits and search engine activity.

Results

A strong positive correlation was observed between epistaxis-related ED visits and search engine activity for the term "nosebleed" (r = 0.655).

Conclusion

Search engine activities for the term "nosebleed" correlates strongly with epistaxis-related ED visits. This study demonstrates the usefulness of utilizing Google Trends search data to assess regional disease burdens, which may provide a means for epidemiological study that is quicker than conventional methods.

Potential of four aquatic plant species to remove 60 Co from contaminated water under changing experimental conditions

Abstract

This study aimed to compare the potential of Lemna minor, Spirodela sp., Eichhornia crassipes and Pistia stratiotes to remove ⁶⁰Co from a realistic aquatic environment. Although all four plant species performed similarly well after 3 days of exposure to 50 kBq L^{−1 60}Co, Lemna minor and Spirodela sp. came forward as having higher ⁶⁰Co removal potential. This conclusion is, in first instance, based on the high ⁶⁰Co removal percentage obtained after a short contact time (e.g. more than 95% could be removed after 6 h by Spirodela sp.). Additionally, Lemna minor and Spirodela sp. accumulated a high amount of ⁶⁰Co per gram of biomass. For example, Lemna minor accumulated over three times more ⁶⁰Co per gram of biomass compared to Pistia stratiotes and Eichhornia crassipes. Both plants also performed well in the pH range 5–9. We used Lemna minor to test the influence of the initial ⁶⁰Co concentration (10, 50, 100 and 200 kBq L^{−1 60}Co) on its phytoremediation capacity but no differences could be observed in removal percentage. In addition, it was shown that by optimising the initial amount of biomass, radioactive waste production can be minimised whilst maintaining high ⁶⁰Co removal rates. Our study shows that these aquatic plants can be used for phytoremediation of ⁶⁰Co from contaminated water and can be considered as a "green" addition or alternative for conventional remediation techniques.

Neurootologisches Counseling bei chronischem Tinnitus

Laryngo-Rhino-Otol
DOI: 10.1055/a-0648-4856

Die Diagnostik und Behandlung des Tinnitus erfordert neurootologische Kompetenz und eine ebenso sachgerechte wie für den Tinnitus-Betroffenen verständliche Aufklärung.Leitliniengerecht entscheidend ist – entsprechend der Tinnitus-Leitlinien von 2015 – die „Beratung des Patienten durch den betreuenden Arzt hinsichtlich seiner persönlichen Ätiopathogenese, wie der persönlichen Verarbeitung des Tinnitus, der Prognose, tinnitusverstärkender Faktoren oder das Ohr schädigender Einflüsse".Dementsprechend ist das Ziel die „Entpathologisierung des Symptoms Tinnitus und die Erklärung sowie Einordnung in die heute anerkannten wissenschaftlichen Vorstellungen" 1.So richtig die Leitlinienvorgabe ist, so schwierig kann es im kassenärztlichen Alltag sein, diese Empfehlungen umzusetzen. Nachfolgend soll daher ein 4- bis 5-schrittiges Vorgehen geschildert werden, dass im ärztlichen Gespräch oder in einer Gruppe die wichtigsten Aspekte leitliniengerecht und verständlich vermittelt. Ergänzend dazu wird auch auf hilfreiche Aspekte seelischer Gesundheit eingegangen.Hilfreich dabei ist der reduzierte Tinnitus-Fragebogen (Mini-TF12) 2, der unter anderem über die Homepage der Deutschen Tinnitus-Liga (DTL) kostenfrei ausgefüllt und ausgewertet werden kann.

Nasal Airway Obstruction

Nasal airway obstruction has a significant impact on quality of life and is one of the most common complaints of patients seeking treatment from Otolaryngologist–Head and Neck Surgeons. While nasal airway obstruction is common, its causes can be multifactorial. Focused treatment can help alleviate obstruction while minimizing unnecessary interventions. This issue of Otolaryngologic Clinics of North America is designed to provide a comprehensive overview of the diagnosis, medical and surgical management options, and methods of measuring the extent of initial obstruction and response to nasal airway obstruction treatment.

The role of oral anticoagulants in epistaxis

Abstract

Purpose

The purpose of this retrospective study was to identify the impact of oral anticoagulants on epistaxis with the focus on new oral anticoagulants.

Methods

The study was conducted at the Department  for Ear- Nose- and Throat (ENT), Head and Neck Surgery, Technical University Munich, Germany. All patients presenting in 2014 with the diagnosis of epistaxis to a specialized ENT accident and emergency department were identified and analyzed in clinical data and medication.

Results

600 adult cases, with a median age of 66.6 years were identified with active bleeding. 66.8% of all cases were anticoagulated. Classic oral anticoagulants (COAC) were three times more common in patients than new-generation oral anticoagulants (NOAC). Recurrent bleeding was significantly associated with oral anticoagulants (OAC) (p = 0.014) and bleeding location was most often anterior (p = 0.006). In contrast, severe cases, which required surgery or embolization were significantly more likely in non-anticoagulated middle-aged patients with posterior bleedings (p < 0.05). In our epistaxis cohort, OAC were highly overrepresented (40%) when compared to the general German population (1%) but COAC as well as NOAC played only a minor role in severe courses of epistaxis.

Conclusion

Oral anticoagulation, especially with new-generation drugs, is not associated with more complicated and severe courses of epistaxis, but rather with recurrent bleeding. One should keep this information in mind when triaging the patient in the emergency room and when planning further procedures.

Repair of bony lateral skull base defects equal to or larger than 10 mm by extracorporeally sewed unit-sandwich graft

Abstract

Objective

To see effectiveness of the senior author's repair technique for repair of large (equal to or larger than 10 mm) bony lateral skull base defects.

Study design

Retrospective.

Settings

Secondary/tertiary care center.

Methods

We performed retrospective review of 9 surgeries done in our institution between January 2010 and December 2013 for repair of large lateral bony skull base defects. We defined skull base defects extra-cranially and repaired them intra-cranially. We made an extracorporeal sandwich of autologous fascia-bone-fascia (fascia lata and nasal septal bone) and sewed it together to make it into a unit-sandwich graft. This extracorporeally sewed unit-sandwich graft was then inserted to close the large skull base defects either via (1) a cranial slit-window, or (2) the skull base defect itself. Since skull base is bony, bony repair is preferred. Bone plates that are easily available for skull base repair are calvarial and nasal septal bone. Occasionally, harvest of split calvarial bone carries risk of major complications. We preferred nasal septal bone. Harvesting of septal bone even in children using a posterior incision should not disturb the cartilage growth centers.

Results

All nine patients were operated by this technique. We had four patients with cerebrospinal fluid leak, and five patients with brain herniation. All these patients had complete reversal of herniation of cranial contents and cessation of cerebrospinal fluid leak. On imaging, in 6 cases the bone graft remained in original intended position after 12 months of surgery. The bone graft was not identifiable in 3 cases.

Conclusion

The senior author's technique using autologous multi-layered graft is simple to master, repeatable and very effective.

Polypoid change of middle turbinate is associated to an increased risk of polyp recurrence after surgery in patients with chronic rhinosinusitis with nasal polyps

Abstract

Background

Chronic rhinosinusitis with nasal polyps (CRSwNP) affects approximately 4% of general population. Patients with CRSwNP have greater burden of CRS symptoms and higher rate of relapse after either medical or surgical treatments. The aim of this study was to evaluate the association between polypoid change of anterior free border of middle turbinate and rate of relapse in patients with CRSwNP.

Methods

A controlled prospective cohort study was performed. Seventy-seven adult patients with CRSwNP in whom their MT polypoid change was proved and 77 patients without MT polypoid change were recruited. Allergy, asthma, aspirin hypersensitivity, Lund Kennedy and Lund Mackay scores and eosinophilic scores of polyp and middle turbinate were recorded. Patient's health-related quality of life was assessed using the 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaire. All patients were evaluated 12 months after ESS. Polyp relapse, Lund Kennedy scores and SNOT-22 scores were documented.

Results

The relapse rate in patients with MT polypoid change was significantly higher than the control group (37.14 vs. 20.58, p value = 0.03). Eosinophil score of nasal polyps and MT specimens were significantly higher in patients with MT polypoid change than patients without polypoid change. The postoperative Lund Kennedy and SNOT-22 scores in patients with MT polypoid change were significantly higher than the control group.

Conclusion

This study showed a significant association between polypoid change of anterior free border of middle turbinate and nasal polyp relapse. This new and simple criterion of severity of CRSwNP could have clinical implications.

Quality assurance in head and neck surgery: special considerations to catch up

Abstract

Purpose

Quality assurance is much more difficult to achieve in surgical oncology than in medical oncology and radiotherapy where doses are standardized and toxicities are well-classified. To better define what is required in surgery, we analyzed recent articles addressing the point in head and neck surgery.

Results

The surgical report should match with the pathological description of the resected specimen with accurate delineation of the margins, number and level(s) of lymph nodes (capsular rupture if any). Complications (minor and major) should be standardized and meticulously recorded; as well as comorbidities and patient status. The acuity of the procedure should be defined by metrics collected in check-lists. Age > 60 years, male gender, tumor site and T₄ stage, neck dissection(s), flap reconstruction, alcohol and tobacco consumption, are acknowledged risk factors for more complications and longer hospital stay (or readmission).

Needs

Randomized controlled trials should be designed adopting the consolidated standards of reporting trials (CONSORT). Training young head and neck surgeons should encompass formation in designing, conducting and interpreting clinical trials.

The diagnostic value of TROP-2, SLP-2 and CD56 expression in papillary thyroid carcinoma

Abstract

Objective

The study aimed to explore some novel diagnostic biomarkers for papillary thyroid carcinoma (PTC) by identifying the different expression of TROP-2, SLP-2 and CD56 in benign and malignant thyroid lesions.

Methods

We evaluated the mRNA expressions of TROP-2 and SLP-2 in fine needle aspirates (FNAs) which contained 10 PTCs and 10 benign follicular adenomas (FAs) using quantitative real-time PCR (qRT-PCR). Immunohistochemical (IHC) staining of TROP-2, SLP-2 and CD56 was also performed on postoperative samples of 30 PTCs and 29 FAs. Membranous or cytoplasmic staining in > 10% of cells was considered as positive. Diagnostic sensitivity, specificity, positive predictive value, negative predictive value (NPV) and diagnostic accuracy of these three biomarkers were carried out. We further analyzed the associations between the clinical features and the expressions of markers in PTCs.

Results

The mRNA expressions of both TROP-2 and SLP-2 were increased substantially in PTCs in comparison with those in FAs (P < 0.05). Similarly, IHC for these two proteins demonstrated higher positive staining in PTCs than in FAs (96.5% vs. 12.5% for TROP-2, 83.3% vs. 20.7% for SLP-2, P < 0.05). Conversely, CD56 expression was lost with 86.7% of PTCs. In identifying malignancy, TROP-2 was the most sensitive marker and CD56 was the most specific one. When the markers were combined, the sensitivity and NPV increased to 100% and had better diagnostic accuracy. However, no association was found between biomarker expressions and clinicopathological factors in PTCs.

Conclusions

We found that TROP-2, SLP-2 and CD56 were effective diagnostic markers for PTC, especially when they were combined to use.

Otogenic lateral sinus thrombosis in children: proposal of an experience-based treatment flowchart

Abstract

Purpose

To describe the prevalent clinical, laboratory, and radiological features of otogenic lateral sinus thrombosis (OLST) in children; to identify clinical predictors of outcome; to propose a management algorithm derived from experience.

Methods

A retrospective review was conducted of the clinical records of patients with OLST, treated in a single tertiary care referral center for pediatric disease from 2006 to 2017. The inclusion criteria were pediatric age (0–16 years) and OLST diagnosis confirmed by a pre- and post-contrast CT or venography–MRI scan. Primary outcome measures were early (1–2 months) and late (6 months) sinus recanalization assessed by means of neuroimaging.

Results

Twenty-five patients (8 females and 17 males; mean age = 6 ± 3 years) were included. A genetic abnormality associated with thrombophilia was found in 24 (96%) patients. At diagnosis, anticoagulant treatment with low-molecular-weight heparin (LMWH) was started in all subjects, while surgical treatment (mastoidectomy and tympanostomy tube insertion) was performed in 16/25 (64%) patients. Follow-up neuroimaging showed lateral sinus recanalization in 12/25 (48%) patients after 1–2 months and in 17/25 (68%) after 6 months. At multivariate logistic regression analysis, no significant predictors of the early and late neuroradiological outcome were found.

Conclusions

All children with OLST should be screened for thrombophilia to decide on treatment duration and to assess the need for future antithrombotic prophylaxis. Immediately after diagnosis, anticoagulant treatment with LMWH should be started according to the international guidelines. Instead, our experience suggests that surgical treatment should not be indicated in all patients, but decided on a case-to-case basis.

Role of asthma and intolerance to acetylsalicylic acid on the redox profile in nasal polyp tissue

Abstract

Purpose

Nasal polyposis is a chronic inflammatory disease of the mucosa of the nasal cavity and paranasal sinuses. The etiology of nasal polyposis is unclear; however, it may be associated with asthma and intolerance to acetylsalicylic acid, possibly altering the redox profile. The study intends to compare the redox profile in polyps surgically removed from three clinical groups of patients with nasal polyposis who were divided according to the presence of asthma and intolerance to acetylsalicylic acid.

Methods

Patients were divided into three groups: nasal polyposis only (n = 30); nasal polyposis and asthma (n = 19); and nasal polyposis, asthma and intolerance to acetylsalicylic acid (n = 10). The following redox evaluations were performed: enzymatic antioxidant activity of superoxide dismutase, glutathione peroxidase, hydrogen peroxide consumption and glutathione S-transferase; non-enzymatic antioxidant levels of vitamin C, vitamin E and glutathione; levels of the oxidative damage biomarkers carbonyl groups (measuring protein damage) and malondialdehyde (measuring lipid peroxidation); and nitrite and nitrate levels.

Results

Compared with the polyposis only group, hydrogen peroxide consumption, glutathione S-transferase, vitamin E and malondialdehyde were lower in the asthma group. Total glutathione (0.12 ± 0.01 vs. 33.34 ± 10.48 µmol/mg) and nitrite and nitrate (0.06 ± 0.01 vs. 15.95 ± 1.38 nmol/mg) levels were higher in the nasal polyposis, asthma and intolerance to acetylsalicylic acid group.

Conclusions

In patients with nasal polyposis, asthma may alter the redox profile associated with the hydrogen peroxide and lipid damage pathways, whereas asthma and intolerance to acetylsalicylic acid increase nitrite and nitrate and total glutathione levels.

Length of the ossified stylohyoid complex and Eagle syndrome

Abstract

Purpose

To assess radiographically the presence of an ossified stylohyoid complex (OSHC) with signs and symptoms of Eagle syndrome or other oro-facial painful diseases in patients attending our institution and to confirm that the important issue for study is to know the length of the ossificated portion of the stylohyoid complex only.

Methods

We separated 1000 consecutive files, and after selection, 922 panoramic radiographs were evaluated. Assessed parameters were gender and age of the patients, size, and location of the analyzed OSHCs. In addition, the length parameters of the studied OSHCs were also determined in 100 extra radiographs.

Results

Normal length of OSHCs was between 2.83 and 4.16 cm and OSHCs measuring more than 4.17 cm long comprising 23.2% of the sample. Any of the patients with OSHC presented signs or symptoms of the Eagle syndrome or any other orofacial painful disease.

Conclusions

This is the first study on OSHCs using the mandatory parameters of normal, short and elongated length in the studied population. Our results suggest that the presence of an OSHC is not an important feature for pain detection in the Eagle syndrome and is not an important risk factor for development of throat pain in this and other painful orofacial diseases. Our results are different from those previously published in other populations and suggest that the widely used lengths of 2 to 4 cm for measuring the OSHCs are not adequate parameter. It is desirable to define first the short, normal and abnormal parameters of OSHCs in each studied population.

SPECT/CT-guided lymph drainage mapping for the planning of unilateral elective nodal irradiation in head and neck squamous cell carcinoma

Abstract

Purpose

To investigate the feasibility of lymph drainage mapping (LDM) using SPECT/CT to help select head and neck cancer (HNSCC) patients for unilateral elective neck irradiation (ENI). Patients with lateralized HNSCC treated with radiotherapy routinely undergo bilateral ENI, despite the incidence of contralateral regional failure being relatively low even after unilateral ENI. We hypothesized that patients with a lateralized tumor without visible lymph drainage to the contralateral neck have an extremely low risk of contralateral involved nodes. Excluding the contralateral neck from elective irradiation will reduce radiation-induced toxicity and improve quality-of-life.

Methods

Fifty-five patients with lateralized cT1-3N0-2bM0 HNSCC not crossing the midline underwent LDM. Radiolabeled ^99mTc-nanocolloid was injected in 4–5 depots around and in the primary tumor. Lymph drainage patterns were visualized using planar scintigraphy and SPECT/CT after 4 h. We report on the incidence of contralateral drainage, the location of draining areas, and the size of underlying nodes.

Results

Lymphatic drainage was successfully visualized in 54 patients (98%). In 11 patients (20%) with visible contralateral drainage, 14 draining areas (16 nodes; median volume 0.50 cc, diameter 8.0 mm) were identified. Neck levels with contralateral drainage were level II (88%), III (25%), and IV (13%). Contralateral drainage was significantly higher in T3 compared to T1–2 tumors (45 and 14%, respectively, P = 0.035).

Conclusion

SPECT/CT-guided LDM is feasible and can be used to guide unilateral ENI in HNSCC patients in prospective studies. In addition, the anatomical confidence in visualization of contralateral drainage indicates a potential for ENI limited to draining levels alone.

IgG4-related disease: association between chronic rhino-sinusitis and systemic symptoms

Abstract

Purpose

The objective of this study is to analyze the relationship between chronic rhino-sinusitis (CRS) and systemic symptoms in patients with IgG4-related disease (IgG4-RD).

Patients and methods

The patients with IgG4-RD, confirmed by restrict association with clinical and histopathological manifestations between March 2013 and July 2016, were enrolled and followed-up for 1 year at the Tongren Hospital, Capital Medical University. The patients were divided into two groups: the case group included IgG4-RD patients with CRS confirmed by clinical and imaging, while the control group included IgG4-RD patients without CRS confirmed by clinical and imaging. Age, gender, clinical manifestations, the percentage of eosinophils in peripheral blood, sedimentation (ESR), C-reaction protein, serum IgE and IgG4 levels, histopathology, and treatment drugs at the baseline and 1 year of follow-up were compared between the two groups.

Results

A total of 46 cases met the diagnostic criteria for IgG4-RD. A total of 30 patients (65.2%) had IgG4-RD complicated with CRS, and were aged 49.7 ± 13.4 years, with male:female ratio = 2:1. The disease duration in the case group was longer than that in the control group (3.0 versus 0.8, p = 0.009). The ratio of ocular involvement was higher (86.7 versus 60%, p < 0.001), and allergic manifestations including drug allergy, asthma, and allergic skin were more common (56.5 versus 20%, p = 0.004), with a higher percentage of eosinophils in peripheral blood (8.5 versus 3.3%, p = 0.018) and more sensitive to glucocorticoids (6.0 versus 3.5, p = 0.004) than those in the control group.

Conclusions

CRS in patients with IgG4-RD was closely associated with IgG4-related ocular lesions, which was more prone to allergic manifestations accompanied by raised percentage of eosinophils in peripheral blood. The treatment of patients with IgG4-RD complicated with CRS was more effective than those with IgG4-RD without CRS.

Subjective effects of the sleep position trainer on snoring outcomes in position-dependent non-apneic snorers

Abstract

Purpose

To evaluate the effect of a new-generation positional device, the sleep position trainer (SPT), in non-apneic position-dependent snorers.

Methods

Non-apneic position-dependent snorers with an apnea–hypopnea index (AHI) < 5 events/h were included between February 2015 and September 2016. After inclusion, study subjects used the SPT at home for 6 weeks. The Snore Outcome Survey (SOS) was filled out by the subjects at baseline and after 6 weeks, and at the same time, the Spouse/Bed Partner Survey (SBPS) was filled out by their bed partners.

Results

A total of 36 participants were included and 30 completed the study. SOS score improved significantly after 6 weeks from 35.0 ± 13.5 to 55.3 ± 18.6, p < 0.001. SBPS score also improved significantly after 6 weeks from 24.7 ± 16.0 versus 54.5 ± 25.2, p < 0.001. The severity of snoring assessed with a numeric visual analogue scale (VAS) by the bed partner decreased significantly from a median of 8.0 with an interquartile range (IQR) of [7.0–8.5] to 7.0 [3.8–8.0] after 6 weeks (p = 0.004).

Conclusions

Results of this study indicate that positional therapy with the SPT improved several snoring-related outcome measures in non-apneic position-dependent snorers. The results of this non-controlled study demonstrate that this SPT could be considered as an alternative therapeutic option to improve sleep-related health status of snorers and their bed partners.

Abstract

Antiphospholipid antibodies (aPL) cause vascular thrombosis (VT) and/or pregnancy morbidity (PM). Differential mechanisms however, underlying the pathogenesis of these different manifestations of antiphospholipid syndrome (APS) are not fully understood. Therefore, we compared the effects of aPL from patients with thrombotic or obstetric APS on monocytes to identify different molecular pathways involved in the pathogenesis of APS subtypes. VT or PM IgG induced similar numbers of differentially expressed (DE) genes in monocytes. However, gene ontology (GO) analysis of DE genes revealed disease-specific genome signatures. Compared to PM, VT-IgG showed specific up regulation of genes associated with cell response to stress, regulation of MAPK signalling pathway and cell communication. In contrast, PM-IgG regulated genes involved in cell adhesion, extracellular matrix and embryonic and skeletal development. A novel gene expression analysis based on differential variability (DV) was also applied. This analysis identified similar GO categories compared to DE analysis but also uncovered novel pathways modulated solely by PM or VT-IgG. Gene expression analysis distinguished a differential effect of VT or PM-IgG upon monocytes supporting the hypothesis that they trigger distinctive physiological mechanisms. This finding contributes to our understanding of the pathology of APS and may lead to the development of different targeted therapies for VT or PM APS.

Chemokine Signaling in Allergic Contact Dermatitis: Toward Targeted Therapies

Allergic contact dermatitis (ACD) is a common skin disease that results in significant cost and morbidity. Despite its high prevalence, therapeutic options are limited. Allergic contact dermatitis is regulated primarily by T cells within the adaptive immune system, but also by natural killer and innate lymphoid cells within the innate immune system. The chemokine receptor system, consisting of chemokine peptides and chemokine G protein–coupled receptors, is a critical regulator of inflammatory processes such as ACD. Specific chemokine signaling pathways are selectively up-regulated in ACD, most prominently CXCR3 and its endogenous chemokines CXCL9, CXCL10, and CXCL11. Recent research demonstrates that these 3 chemokines are not redundant and indeed activate distinct intracellular signaling profiles such as those activated by heterotrimeric G proteins and β-arrestin adapter proteins. Such differential signaling provides an attractive therapeutic target for novel therapies for ACD and other inflammatory diseases.

Skin Ceramide Profile in Children With Atopic Dermatitis

Background Atopic dermatitis (AD) is a common disease, which involves a disruption of the skin barrier function. Skin ceramide (CER) composition, which plays crucial roles in maintaining the barrier function of the stratum corneum, is changed in patients with AD. Objective The aim of this study was to identify and quantify skin CER subclasses in association with disease severity in pediatric patients with AD. Methods Two hundred thirteen patients were entered into the observational study. We compared their CER profiles using normal-phase high-performance liquid chromatography coupled with dynamic multiple reaction monitoring mass spectrometry. Results In total, 12 subclasses of CERs were identified. We found that 2 subclasses, that is, CER[AS] and CER[NS], were elevated (P = 0.007 and 0.012, respectively) and correlated with Severity Scoring of Atopic Dermatitis (P = 0.004 and 0.004, respectively). Conclusions Skin CER abundances are changed in children with AD compared with control subjects.

Electrochemical Screening Spot Test Method for Detection of Nickel and Cobalt Ion Release From Metal Surfaces

Background Present screening methods to rapidly detect release of nickel and cobalt ions from metallic surfaces involve colorimetric dimethylglyoxime (DMG)- and disodium-1-nitroso-2-naphthol-3,6-disulfonate–based spot tests with a cotton bud. There is a risk of false-negative test reactions because test outcomes are dependent on the pressure, area, and duration of surface wiping. Objective The aim of the study was to develop a miniaturized electrochemical device that uses a voltage to accelerate nickel and cobalt release from the tested item and perform an initial validation. Methods and Results A device was built in plastic, and its performance was investigated using 0.5 mL of test solutions of, respectively, DMG and disodium-1-nitroso-2-naphthol-3,6-disulfonate. Cotton buds that had been wetted in test solution were pressed against different metal surfaces at various voltages (0–9 V) and a range of test durations (0–120 seconds). Duplicate testing for nickel and cobalt release was also performed on a sample of 163 jewelry items. Conclusions This novel electrochemical device makes it possible to perform nickel and cobalt ion release testing without rubbing, thereby reducing interindividual differences in testing technique. The nickel testing with the device seemed to be superior to conventional DMG spot testing.

Steroid Withdrawal Effects Following Long-term Topical Corticosteroid Use

Background Concerns about topical steroid withdrawal (TSW) are leading some patients to cease long-term topical corticosteroid (TCS) therapy. Diagnostic criteria for this condition do not exist. Objective The aim of this study was to examine the demographics and outcomes in adult patients who believe they are experiencing TSW following discontinuation of chronic TCS overuse. Methods This was a retrospective cohort study of patients in an Australian general practice presenting with this clinical scenario between January 2015 and February 2018. Results Women represented 56% of the 55 patients seen, and ages ranged from 20 to 66 years (mean, 32.9 years; median, 30.0 years). Seventy-six percent had an original diagnosis of atopic dermatitis. Sixty percent had used potent TCSs on the face, and 42% had a history of oral corticosteroid use for skin symptoms. Burning pain was reported in 65%; all had widespread areas of red skin; and so-called "elephant wrinkles," "red sleeve," and the headlight sign were seen in 56%, 40%, and 29%, respectively. Conclusions Patients with a history of long-term TCS overuse may experience symptoms and signs described in TSW on stopping TCSs. Diagnostic criteria, reflecting the histories and examination findings of the patients studied, are suggested in this article with the aim to advance discussion and research into TSW.

Textile and Shoe Allergic Contact Dermatitis in Military Personnel

Background and Objectives Allergic contact dermatitis is a common dermatosis among military personnel. Given the unique military demands, it is not surprising that shoe dermatitis and textile dermatitis are common. Our study aimed to compare the clinical and demographic parameters between military personnel and civilians evaluated for the suspicion of shoe and textile dermatitis in a tertiary clinic in Israel. Methods This retrospective cross-sectional study included 295 patients who were referred to a tertiary clinic for evaluation because of suspected shoe or textile dermatitis. Eighty-eight of the patients were soldiers. The patch tests were tailored according to the clinical presentation and relevant exposures. Results The 2 populations differed in several parameters. The duration of the dermatitis was longer in the civilian group. The atopy rate was significantly higher among military conscripts. The patch test reactivity and multiple patch test reactivity were lower in the army group. Dermatitis seen in the military group tended to be more widely distributed. Conclusions Distinctive demographic and exposure patterns explain the differences observed between the 2 study groups. It is not surprising that irritant dermatitis is more common among military personnel, given the extreme military demands and higher atopy rate among soldiers.

Patch Testing to Propylene Glycol: The Mayo Clinic Experience

Background Propylene glycol (PG) is a solvent, vehicle, and humectant being used increasingly in a wide array of personal care products, cosmetics, and topical medicaments. Propylene glycol is a recognized source of both allergic and irritant contact dermatitis. Objective The aim of the study was to report incidence of positive patch tests to PG at Mayo Clinic. Methods We retrospectively reviewed records of all patients patch tested to PG from January 1997 to December 2016. Results A total of 11,738 patients underwent patch testing to 5%, 10%, or 20% PG. Of these, 100 (0.85%) tested positive and 41 (0.35%) had irritant reactions. Patients also tested to a mean of 5.6 concomitant positive allergens. The positive reaction rates were 0%, 0.26%, and 1.86% for 5%, 10%, and 20% PG, respectively, increasing with each concentration increase. The irritant reaction rates were 0.95%, 0.24%, and 0.5% for 5%, 10%, and 20% PG, respectively. Conclusions Propylene glycol is common in skin care products and is associated with both allergic and irritant patch test reactions. Increased concentrations were associated with increased reactions.

Pediatric Baseline Patch Test Series: Pediatric Contact Dermatitis Workgroup

Background Allergic contact dermatitis is a challenging diagnostic problem in children. Although epicutaneous patch testing is the diagnostic standard for confirmation of contact sensitization, it is less used in children by dermatologists treating children, pediatric dermatologists, and pediatricians, when compared with adult practitioners. Objective The aim of the study was to create and evaluate standardization of a pediatric patch test series for children older than 6 years. Methods We surveyed dermatologists and allergists conducting epicutaneous patch testing in children attending the 2017 American Contact Dermatitis Society meeting held in Washington, DC. This was followed by discussion of collected data and consensus review by a pediatric contact dermatitis working group at the conference. Conclusions A baseline pediatric patch test panel was established through working group consensus.

Transoral approach to Type 1 Laryngeal Cleft Repair: A novel, non-endoscopic technique

Publication date: Available online 19 July 2018

Source: International Journal of Pediatric Otorhinolaryngology

Author(s): Austin N. DeHart, Jonathan R. Korpon, Rajanya S. Petersson

Abstract

Endoscopic type 1 laryngeal cleft repair under spontaneous ventilation can be difficult in patients with poor pulmonary reserve. Intubation makes visualization of the interarytenoid area challenging during an endoscopic repair. As an alternative technique, we utilized a transoral, non-endoscopic approach with a McIvor mouth gag in two such patients. This provided adequate visualization and a larger working field with readily available instrumentation. The ability to intubate the patient obviated the need to intermittently place an endotracheal tube and allowed for uninterrupted working time. This technique does require favorable patient anatomy for adequate exposure, but is worth considering in certain patients.

The OSA-5: Development and validation of a brief questionnaire screening tool for obstructive sleep apnea in children

Publication date: Available online 19 July 2018

Source: International Journal of Pediatric Otorhinolaryngology

Author(s): Han Jie Soh, Katherine Rowe, Margot J. Davey, Rosemary S.C. Horne, Gillian M. Nixon

Abstract

Objective

To develop and test a screening tool based on the OSA-18 questionnaire for triage of referrals for sleep-disordered breathing (SDB) in children.

Study Design

Consecutive children aged >2y without major comorbidities referred for polysomnography (PSG) or overnight oximetry for suspected obstructive sleep apnea (OSA) between 11 January and 31 May 2017 were included. OSA was defined by an obstructive apnea/hypopnea index (OAHI) >1event/h on PSG or an abnormal overnight oximetry (McGill Oximetry Score 2-4). An 11-item questionnaire derived from a previous validation study of the OSA-18 underwent exploratory factor analysis (EFA) with varimax rotation. ANOVA identified questions associated with the presence of OSA. This informed a 5-question, 4-category instrument, scored 0-15 (the OSA-5), that was tested prospectively on 112 children having PSG.

Results

420 children (2.0-17.9y, 43% female) met the inclusion criteria, including 366 complete questionnaires. EFA resulted in a 3-factor structure. ANOVA identified 5 questions from one factor that were independently associated with a diagnosis of OSA: snoring, breath holding, choking, mouth breathing and parental concern. Mean OSA-5 scores with and without OSA were 7.7 vs 4.5 (p<0.001). Thirty-four percent (60/178) had a total score <5/15, with a sensitivity at this threshold for OSA of 82% and negative predictive value (NPV) of 70%. Similar results were obtained when tested prospectively, including a sensitivity of 82% and NPV of 81% for the presence of moderate/severe OSA (OAHI>5/h).

Conclusion

The OSA-5 is a simple questionnaire that performs well as a triage screening tool to identify those children at risk of OSA among large numbers of referrals for SDB.

Author(s): James Johnston, Michael Hoggard, Kristi Biswas, Carmen Astudillo-García, Fiona J. Radcliff, Murali Mahadevan, Richard G. Douglas

Abstract

Introduction

Culture-independent methods, based on bacterial 16 S rRNA gene sequencing, have been used previously to investigate the adenotonsillar microbiota. However, these studies have focused on a single sampling site (usually a surface swab). We aimed to investigate potential differences in adenotonsillar microbiota according to sampling location, both on and within the adenoids and palatine tonsils.

Methods

Pediatric patients (n=28, mean age five years) undergoing adenotonsillectomy were recruited for this study. At the time of surgery, a mucosal adenoid surface swab and an adenoid tissue biopsy was collected. Immediately following surgery, the crypts of the right and left tonsils were swabbed, and a surface and core tissue sample from the right tonsil were also collected. Bacterial 16 S rRNA gene-targeted amplicon sequencing was used to determine the bacterial composition of the collected samples.

Results

There was no significant difference in diversity or composition of the adenoid microbiota based on sampling site. However, the Shannon–Wiener and Inverse-Simpson diversity indices differed significantly (p<0.05) between the microbial communities of the three different tonsil sampling sites. There was a higher average relative abundance of members from the genera Streptococcus, Actinobacillus, and Neisseria in the tonsil crypts when compared with surface and core tonsil tissue samples.

Conclusion

Our results indicate that there is variation in bacterial diversity and composition based on sampling sites in the tonsils but not the adenoids. The difference in microbiota between the surface and the tissue may have implications for our understanding of the pathogenesis of recurrent tonsillitis and have treatment implications.

Renal Ultrasound Abnormalities in Children with Syndromic and Non-Syndromic Microtia

Publication date: Available online 19 July 2018

Author(s): Julie L. Koenig, Misha Amoils, Madeline M. Grade, Kay W. Chang, Mai Thy Truong

Abstract

Objective

Renal abnormalities are commonly considered in the work up of pediatric patients with external ear malformations. However, there is little consensus regarding an appropriate renal screening protocol for patients with microtia. We sought to characterize renal abnormalities detected on ultrasonography in pediatric patients with microtia.

Methods

We conducted a retrospective cohort study of pediatric patients diagnosed with microtia who underwent renal ultrasound from 1991 to 2014 at a single tertiary academic institution. Renal ultrasound reports and medical records were reviewed to assess for renal abnormalities and to determine whether patients required specialist follow-up or interventions. Audiograms and otolaryngology notes were used to determine patterns of hearing loss. The following additional information was recorded from the electronic medical records: patient sex, microtia grade (I-IV), microtia laterality, and known associated syndromes. Characteristics were compared between those who did and did not have renal ultrasound findings using Fisher's exact test. Univariate logistic regression analysis was performed to determine factors associated with renal ultrasound findings.

Results

The majority of patients in this cohort were syndromic (n=51, 64%) with grade III microtia (n=46, 58%) and conductive hearing loss (n=58, 72%). Syndromic children with microtia demonstrated a higher crude rate of renal ultrasound abnormalities (22%) than children with isolated microtia (7%). Of these patients, 69% required specialist follow-up. Univariate logistic regression analysis did not identify predictors that were significantly associated with renal ultrasound findings.

Conclusion

Fairly high rates of abnormalities in syndromic and non-syndromic patients may warrant screening renal ultrasound in all patients with microtia, especially given the high percentage of findings requiring renal follow-up. A prospective study to formally evaluate screening efficacy is needed.

Simultaneous auricular reconstruction combined with bone bridge implantation-optimal surgical techniques in bilateral microtia with severe hearing impairment

Publication date: Available online 19 July 2018

Source: International Journal of Pediatric Otorhinolaryngology

Author(s): Yue Wang, Wenshan Xing, Tun Liu, Xu Zhou, Jin Qian, Bingqing Wang, Shouqin Zhao, Qingguo Zhang

Abstract

Background

Congenital bilateral microtia with external ear canal (EAC)/middle ear malformation lead to severe appearance defects, hearing impairment and language barrier. Here we report an optimal integrated surgical technique for BoneBridge implantation and auricular reconstruction, which reduce time span of operation, total cost and patients' suffering as well.

Method

Seven patients with bilateral external and middle ear malformation received 2-stage auricular reconstruction (age from 7 to 11 years old). In the 1st stage, 6th, 7th, and part of 8th autologous costal cartilage were used to make main body and C-shaped base part of the framework. In 2nd stage of the operation, dissect and lift the framework, isolate postauricular fascia and periosteum, put the BoneBridge subperiosteally and fixed with titanium screw. The C-shaped cartilage base was further attached to the framework and retroauricular fascial flaps and a full-thickness skin graft obtained from the donor site was used to cover posterior raw surface.

Results

Patients were followed up for about 8 months post operation, all of them satisfied with the outcomes and symmetric shape on both sides about desirable 3D detail without adverse complications. Hearing test indicated the mean improvement of auditory threshold of 34.8 dB HL 3 weeks after BoneBridge implantation, with mean scores of speech recognition test ranging from 26%∼62%.

Conclusion

The combined 2-stage surgical techniques of simultaneous auricular reconstruction and BoneBridge implantation is safe and efficient for bilateral microtia with significant advantages in decreasing operation difficuties, shortening treatment span and relieving suffering for patients.

Temporary olfactory improvement in chronic rhinosinusitis with nasal polyps after treatment

Abstract

Purpose

Olfactory dysfunction in chronic rhinosinusitis with nasal polyps (CRSwNP) is a severe type of inflammatory olfactory disorders which greatly impair quality of life. The aim of this review is to summarize the current literature and to provide a comprehensive guide to the key metrics of the olfactory dysfunction, evaluations, treatment responses, and pathophysiological mechanisms in CRSwNP patients with olfactory dysfunction.

Methods

A review of the literature for olfaction in CRSwNP was conducted. The key terms ("chronic rhinosinusitis", "nasal polyps", and "olfaction") were used to search relevant articles in Pubmed.

Results

Inflammation within the olfactory cleft is a well-recognized cause of the olfactory loss in patients with CRSwNP. Although the current treatment could significantly improve the olfactory function, olfaction in patients with CRSwNP tends to deteriorate after temporary improvement. Recent research has focused on the change of olfactory cleft and its association with the olfactory function which shed light on the mechanisms of both conductive and sensorineural olfactory dysfunctions in patients with CRSwNP. The state of the olfaction in patients with CRSwNP is directly associated with the degree of inflammation control and disturbed normal turnover of the olfactory sensory neurons induced by chronic inflammation, especially the eosinophilic inflammation contributes to the olfactory dysfunction. Refractory factors contributing to the olfactory deterioration are the promising therapeutic target to maintain the olfactory function in patients with CRSwNP.

Conclusions

The current evidence supports temporary olfactory improvement in CRSwNP patients which accords with the refractory nature of CRSwNP. Future treatment should aim to the continuous elimination of inflammation and promote the normal turnover of the olfactory epithelium.

Evaluation of surgical margin status in patients with early glottic cancer (Tis-T2) treated with transoral CO 2 laser microsurgery, on local control

Abstract

Purpose

To assess the impact of surgical margins status on local control in patients with primary early glottic (Tis-T2) squamous cell carcinoma after treatment with transoral CO₂ laser microsurgery (TLM) and to assess the significance of additional wound bed biopsies.

Methods

Patients with Tis-T2 tumours treated with TLM type I–III resections according to the European Laryngological Society classification between 2009 and 2013 were included in retrospective analysis. Recurrence rate was determined in patients with free versus non-free specimen margins and wound biopsies. Five-year survival rates were determined using the Kaplan–Meier method. Prognostic impact of pT-category, resection margin status, tumour differentiation, wound bed biopsy status, and number of biopsies on local control (LC) were tested with the log-rank test.

Results

Eighty-four patients were included in the analysis. Positive margins were seen in 68 patients (81.0%). Margin status after TLM did not significantly influence LC (p = 0.489), however, additional wound bed biopsies were significantly associated with lower LC (p = 0.009). Five-year LC, disease-specific survival, overall survival and laryngeal preservation were 78.6, 78.0, 98.6 and 100%, respectively.

Conclusions

Additional wound bed biopsies can help predict local recurrence in patients treated with TLM for early glottic carcinoma. We propose that there is enough evidence to support a wait-and-see policy in patients with positive specimen margins and negative wound bed biopsies. For patients with positive wound bed biopsies, further treatment is warranted.

Early corrected serum calcium value can predict definitive calcium serum level after total thyroidectomy in asymptomatic patients

Abstract

Introduction

Hypocalcemia is the most common complication of thyroidectomy, requiring supplementation as well as prolonged hospitalization. Our study's objective was to determine a corrected calcium (CCa) level on day 1 after thyroidectomy predictive of no calcium and vitamin supplementation.

Materials and methods

A single-center prospective study conducted between January 2012 and July 2015 in 396 patients, consisting of 331 cases of total thyroidectomy, with seven completion surgeries. The data collected were age, sex, type of thyroid surgery, etiology, anatomical pathological analysis, and the need for calcium and vitamin supplementation therapy as well as its duration. CCa levels were analyzed 20 and 30 h after surgery then on days 2 and 3. To determine a cut-off value for CCa, a ROC curve analysis was performed. The population was described in terms of numbers and associated percentages for categorical variables, and mean.

Results

Mean CCa on 20 h after surgery was 2.09 mmol/L (p < 0.001) and 30 h was 2.06 mmol/L p = 0.02. CCa of less than 2.13 mmol/L was predictive of calcium and vitamin supplementation with 56% sensitivity and 97% specificity. On the evening of day 1, the cut-off value for CCa was 2.06 mmol/L with 67% sensitivity and 65% specificity.

Conclusion

This prospective study confirms that CCa on the first morning after surgery is reliable when it is more than 2.13 mmol/L. In total, analyzing CCa on day 1 after total thyroidectomy allows the discharge of 70% of patients on the first day after surgery, with no risk of hypocalcemia.

Treatment of synthetic dye baths by Fenton processes: evaluation of their environmental footprint through life cycle assessment

Abstract

Inorganic and organic constituents present in textile effluents have a noticeable effect on the performance of Fenton processes. However, studies have been focused on simple wastewater matrices that do not offer enough information to stakeholders to evaluate their real potential in large-scale facilities. Chemical auxiliaries, commonly present in textile wastewaters (NaCl = 30 g/L, Na₂CO₃ = 5 g/L, and CH₃COONa = 1 g/L), affect both the economic and environmental performance of the process because they increase the treatment time (from 0.5 to 24 h) and the consumption of H₂SO₄ (657%) and NaOH (148%) during conditioning steps. The life cycle assessment (LCA) performed with the IPCC-2013 method revealed that dyeing auxiliaries increase from 1.06 to 3.73 (252%) the emissions of carbon dioxide equivalent (CO₂-Eqv/m³). Electricity consumption can be considered an environmental hotspot because it represents 60% of the carbon footprint of the Fenton process. Also, the presence of auxiliaries is critical for the process because it results in the increase of the relative impact (between 50 and 80%) in all environmental categories considered by the ReCiPe-2008 method. Chemical auxiliaries increased the costs of the treatment process in 178% (US$2.22/m³) due to the higher energy consumption and the additional reagent requirements. It is worthwhile mentioning that the technical simplicity of the Fenton process and its low economic and environmental costs turn this process into an attractive alternative for the treatment of textile effluents in emerging economies.

Measuring herpes zoster disease burden in São Paulo, Brazil: a clinico-epidemiological single-center study

OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.
