Purpose of review Symptomatic management of chronic spontaneous urticaria (CSU) basically depends on second-generation H1 antihistamines and omalizumab. Omalizumab is a game changer in the management, but still there is a need for new targets and new biologics targeting new pathways in the treatment which will provide long-lasting remission, which will be given orally and which will be cheaper. This review will focus on new biologics that are underway of production or are already under use for different disorders but could be beneficial for the treatment of Chronic urticaria. Recent findings In this review, the treatment targets are classified according to the cells which are involved in the pathogenesis of CSU. Those are mast cells/basophils, B cells, T cells and eosinophils. The treatments that are under clinical trials for CSU are anti-IgE treatments such as ligelizumab, molecules targeting intracellular signaling pathways such as spleen tyrosine kinase inhibitors, surface inhibitory molecules such as siglec-8, anti-IL-1s such as canakinumab, Bruton kinase (BTK) inhibitors such as GDC-0853 and anti-IL-5s such as benralizumab and mepolizumab. Summary The ongoing clinical trials on new targets of treatment hold new hopes not only for a better care of the disease but also a better understanding of the pathomechanisms lying underneath.

Ocular allergy as a risk factor for dry eye in adults and children
Purpose of review To provide an overview of the pathogenic mechanisms underlying the correlation between ocular allergy and dry eye disease (DED), highlighting how the first condition may be a risk factor for the second one. Recent findings Recent advances in our comprehension of the pathogenesis of ocular allergy and DED allow identifying several pathways of interaction between these two conditions. A growing body of evidence supports the role of ocular allergy as a risk factor for DED. Ocular allergy, particularly the severe forms of keratoconjunctivitis, can impact on different key mechanisms of the DED vicious cycle, including tear film instability, ocular surface inflammation and damage, and neurosensory abnormalities. Summary Ocular allergy and DED are two common, relevant, symptomatic, not mutually exclusive conditions affecting the ocular surface. They share some clinical and biochemical features. To better understand the complex interactions between these two conditions, it's essential to consider the very wide spectrum of clinical conditions included in the term ocular allergy and the still largely unexplored peculiarities of the pediatric ocular surface physio-pathology and DED.

Precision medicine in food allergy
Purpose of review To familiarize the reader with the concept of precision medicine in food allergy through the most recent insights in the diagnosis, prognosis, and management of the disease. Recent findings With the advent of omics sciences, a new era is commencing. Food protein allergens characterization and quantification together with the immunoglobulin E epitope mapping will contribute to the diagnosis/prognosis of food allergy and will lead to a better safety assessment of foods. The characterization of biomarkers able to identify specific phenotypes and endotypes will improve the diagnostic accuracy. This together with a better understanding of mechanisms of action of the different therapeutic options will allow the accurate selection of the appropriate patient. Summary In the near future, advances in technologies and data interpretation will allow a better understanding of the pathogenesis of food allergy and the development of a personalized treatment tailored on the specific patient' profile.

Which Protocol for Milrinone to Treat Cerebral Vasospasm Associated With Subarachnoid Hemorrhage?
Background: Milrinone has emerged as an option to treat delayed cerebral ischemia after subarachnoid hemorrhage. However, substantial variation exists in the administration of this drug. We retrospectively assessed the effectiveness of 2 protocols in patients with angiographically proven cerebral vasospasm. Methods: During 2 successive periods, milrinone was administered using either a combination of intra-arterial milrinone infusion followed by intravenous administration until day 14 after initial bleeding (IA+IV protocol), or a continuous intravenous milrinone infusion for at least 7 days (IV protocol). The primary endpoint was the reversion rate of vasospastic arterial segments following the first IA infusion of milrinone (IA+IV protocol) compared with the reversion rate during the first week of IV infusion (IV protocol). Results: There were 24 and 77 consecutive patients in IA+IV and IV protocols, respectively. The reversion rate was comparable between the 2 protocols: 71% (95% confidence interval [CI], 59%-83%) in the IA+IV protocol versus 64% (95% CI, 58%-71%) in the IV protocol (P=0.36). Rescue procedures for persistence or recurrence of vasospasm, that is, mechanical angioplasty and/or IA milrinone infusion, were similar between the 2 protocols. Patients with a good neurological outcome at 1 year, that is, modified Rankin Scale scores 0-2, were comparable between the 2 protocols. Side effects of milrinone were uncommon and equally distributed within the 2 protocols. Conclusions: These findings indicate that a continuous IV infusion of milrinone was as efficient as combined IA+IV infusion and suggest that this modality could be considered as a first easy-to-use option to treat patients with CVS.

Impact of CPAP on Forehead Near-infrared Spectroscopy Measurements in Patients With Acute Respiratory Failure: Truth or Illusion
Background: Critically ill patients with acute respiratory failure admitted to an intensive care unit are at high risk for cerebral hypoxia. We investigated the impact of continuous positive airway pressure (CPAP) therapy on regional cerebral tissue oxygenation (rSO2). Materials and Methods: In total, 40 extubated surgical intensive care unit patients requiring classic oxygen therapy (COT) for acute respiratory failure were examined. Near-infrared spectroscopy (INVOS 5100C, Covidien) was used for 30 minutes to detect bilateral rSO2 during COT via facemask (6 L/min) and CPAP therapy (40% fraction of inspired oxygen, 8 cm H2O CPAP) using a randomized crossover study design. Patients served as their own control. Continuous hemodynamic routine monitoring and blood gas analysis were performed. The effect of CPAP therapy on rSO2 and influence of assessed covariables were investigated using a mixed linear model. Results: Median rSO2 increased from 57.9% (95% confidence interval [CI], 54.2-61.5) during COT to 62.8% (95% CI, 59.2-66.5) during CPAP therapy (P

Multiple lesions of skull and cervical spine: a rare presentation of unicameral bone cysts
A 55-year-old man with a history of Benign Paroxysmal Positional Vertigo unalleviated by Epley manoeuvre presented to an otolaryngologist for dizziness, right ear fullness and headache. MRI of the brain showed numerous marrow-replacing lesions throughout the calvarium, skull base and upper cervical spine which were hypointense on T1-weighted images, hyperintense on T2-weighted images and avidly enhanced following contrast, concerning for a malignant process such as metastatic disease or multiple myeloma (figure 1). Systemic X-ray survey (spine, skull, chest, pelvis, all long bones) and nuclear medicine whole body bone scan were negative except for the lesions seen on MRI. β–2microglobin, immunoglobin and monoclonal protein electrophoresis were negative for myeloma or immunological process. Given the concern for metastatic disease, biopsy of a skull lesion was recommended. Pathological analysis of a calvarial lesion was consistent with unicameral bone cyst (figure 1). No ongoing therapy was offered; however, brain and spine surveillance imaging will continue.

Orbitocerebral mucormycosis and intracranial haemorrhage: a role for caution with steroids in suspected giant cell arteritis
A 75-year-old man with type 2 diabetes mellitus presented with complete loss of vision in his right eye and severe headaches for the past 24 hours. He had been treated for suspected giant cell arteritis (GCA) with high-dose corticosteroids which were being tapered to stop after an inconclusive right temporal artery biopsy and an erythrocyte sedimentation rate (ESR) value of 8. His current acute presentation, however, raised further concern for partially treated GCA and precipitated treatment with pulsed methylprednisolone. The patient, taking metformin, developed diabetic ketoacidosis and was transferred to the intensive care unit where a swollen, painful right eye with chemosis and complete ophthalmoplegia was subsequently revealed to be secondary to cavernous sinus thrombosis. Rhino-orbital skin necrosis with positive samples for the organism Rhizopus on eventual orbital exenteration revealed angioinvasive fungal infection, mucormycosis, to be the cause. We discuss here the lessons learnt, and how best to treat a susceptible cohort within our ageing western population.

Spontaneous migration into the stomach and out of the intestine, as late complication of a gastric band
Description
A 45-year-old woman with morbid obesity (body mass index 44 kg/m²) presented to the emergency department with severe abdominal pain, nausea, vomiting and no defaecation. She had a laparoscopic adjustable gastric banding (LAGB) inserted elsewhere in 2006. No data or follow-up was performed postoperatively. A CT scan demonstrated a perforated LAGB through the gastric antrum (figure 1). Furthermore the connecting tube perforated the small intestine at the level of the proximal part of the jejunum with a partially intraluminally positioned banding (figure 2), causing prestenotic dilatation of the jejunum (figure 3). An upper gastrointestinal endoscopy confirmed an intact port site with a connected tube and migration and perforation of the band into the jejunum with an erosion of the gastric (figure 4) and duodenal wall. At closer inspection of the port site and connecting tube, we observed a high level...

Emphysematous Osteomyelitis
Description
A 56-year-old man with a known history of type 2 diabetes mellitus, hypertension, nephrolithiasis and gout presented with fatigue and flank pain for 3 days. The above symptoms were associated with fevers and chills. On admission, the patient's vitals were remarkable for fever with maximum temperature (T max) 39.1°C, hypotension requiring pressor support and tachycardia. On auscultation, he had reduced air entry at lung bases, distended abdomen, bipedal oedema and petechial rash over the upper extremities and the trunks. In addition, there was purplish discolouration over the left medial sacral area. Laboratory work-up was remarkable for elevated white cell count 21.4x109/L (4.0–12.0x109/L), creatinine 7.98 mg/dL (0.60–1.40 mg/dL), anion gap of 25, erythrocyte sedimentation rate of 70 mm/hour (0–20 mm/hour), total bilirubin of 4.9 mg/dL (0.2–1.2 mg/dL) and lipase 422 U/L (0–140 U/L). Platelet count was 31x103/µL (150–400 103/µL), aspartate aminotransferase of 71 U/L (10–40 U/L) and alanine aminotransferase of 37 U/L (3–45 U/L). Septic shock was suspected, and the patient was...

Campylobacter fetus spondylodiscitis in a patient with HIV infection and restored CD4 count
Campylobacter fetus (C. fetus) is a rare condition and mostly seen in elderly or immunocompromised patients. We present the first case of C. fetus spondylodiscitis in a virologically suppressed HIV seropositive patient with low back pain. MRI was performed and showed spondylodiscitis of the L4–L5 region. Empirical antibiotic therapy with flucloxacillin was started after blood cultures were drawn and an image-guided disc biopsy was performed. Blood cultures remained negative. The anaerobic culture of the puncture biopsy of the disc revealed presence of C. fetus after which the antibiotic treatment was switched to ceftriaxone. Guided by the susceptibility results, the therapy was switched to ciprofloxacin orally for 6 weeks after which the patient made full clinical, biochemical and radiographic recovery. Since no other immune-deficient conditions were noted, it is important to highlight that patients with HIV infection with restored CD4 counts and complete virological suppression can still be susceptible for infections caused by rare pathogens. Low back pain should raise suspicion for these conditions and should be examined properly.

Case of fatal familial insomnia caused by a d178n mutation with phenotypic similarity to Hashimotos encephalopathy
Fatal familial insomnia (FFI) is a rare prion disease commonly inherited in an autosomal dominant pattern from a mutation in the PRioN Protein (PRNP) gene. Hashimoto's encephalopathy (HE) is characterised by encephalopathy associated with antithyroid peroxidase (TPO) or antithyroglobulin (Tg) antibodies. These two conditions characteristically have differing clinical presentations with dramatically different clinical course and outcomes. Here, we present a case of FFI mimicking HE. A woman in her 50s presented with worsening confusion, hallucinations, tremor and leg jerks. Several maternal relatives had been diagnosed with FFI, but the patient had had negative genetic testing for PRNP. MRI of brain, cervical and thoracic spine were unremarkable except for evidence of prior cervical transverse myelitis. Cerebrospinal fluid analysis was normal. Anti-TPO and anti-Tg antibodies were elevated. She was started on steroids for possible HE and showed improvement in symptoms. Following discharge, the results of her PRNP gene test returned positive for variant p.Asp178Asn.

Rare cause of voiding dysfunction in an adult man: urethral diverticulum compressing the anterior urethra
Description
A 46-year-old man presented to us with lower urinary tract symptoms that include severe voiding symptoms. He had a history of injury to the perineum 3 years back. A smooth cystic swelling was palpable in the perineum in midline. Uroflowmetry was done and was suggestive of poor urinary flow (Qavg: 2 mL/s and Qmax: 6 mL/s), with significant postvoid residual urine (PVR). A micturating cystourethrogram (MCU) with retrograde urethrography (RUG) was done and was suggestive of an anterior urethral diverticulum, which was compressing the urethra, along with significant PVR (figure 1). The patient was planned for open excision of the urethral diverticulum. A cystourethroscopy was done preoperatively and clearly showed a normal anterior urethra and the opening of the diverticulum on the ventral aspect of the urethra (figure 2). The patient was operated in lithotomy position and a midline perineal incision was done. The diverticulum was dissected free and then excised,...

Dekubitus erkennen und richtig klassifizieren: ein Positionspapier
Zusammenfassung
Hintergrund
Dekubitalulzera sind schwerwiegende Haut- und Gewebeschäden. Die korrekte Diagnose und Einteilung in verschiedene Kategorien gestaltet sich in der Praxis oft schwierig.
Fragestellung
Welches Vorgehen kann empfohlen werden, um Dekubitalulzera in der Praxis richtig zu diagnostizieren und zu klassifizieren?
Material und Methoden
Die Initiative Chronische Wunden (ICW) e. V. berief eine Expertengruppe ein, die, basierend auf der aktuellen Literatur und eigener Expertise, praktische Empfehlungen für die Diagnostik und Klassifikation von Dekubitalulzera entwickelte.
Ergebnisse
Die Diagnose Dekubitus soll nur dann gestellt werden, wenn Haut- und/oder Gewebeschäden mit hoher Wahrscheinlichkeit infolge von länger andauerndem Druck oder Druck in Verbindung mit Scherkräften entstanden sind. Es muss eine vollständige Anamnese durchgeführt werden, um Phasen von vorhergehender längerer Immobilität zu erfassen. Dekubitalulzera befinden sich in der Regel an typischen Prädilektionsstellen. Bei der Kategorie I und „vermuteter tiefer Gewebeschädigung" liegen Gewebeschäden unter (zunächst) intakter Haut vor. Die Diagnose ist jedoch unsicher, und die Klassifikation soll erst im weiteren Verlauf vorgenommen werden. Ein Kategorie-II-Dekubitus ist in der Regel eine Ausschlussdiagnose. Die Kategorien III und IV sind Dekubitalulzera im eigentlichen Sinn. Solange die Abgrenzung zwischen Kategorie III und IV nicht möglich ist, soll die niedrigere Kategorie kodiert werden.
Schlussfolgerungen
Derzeit soll passend für das jeweilige Setting einheitlich eine relevante Klassifikation verwendet werden. Die am besten dem klinischen Bild entsprechende Diagnose kann dann gestellt werden. Dabei ist es unerheblich, welches Klassifikationssystem verwendet wird. Mithilfe der zukünftig zu erwartenden Version des ICD-11 der WHO können Dekubitalulzera dann besser klassifiziert werden.

Assessment of healthiness among long term inhabiting army soldiers in dry zone of Sri Lanka.
BMC Res Notes. 2018 Jul 13;11(1):474
Authors: Jayaweera JAAS, Joseph A
Abstract
OBJECTIVES: Military personnel, because of the unique nature of their duties, are reluctant to face stressors. Living in hot and humid conditions they frequently suffer dehydration. Army soldiers living in dry zone of Sri Lanka, were screened for chronic kidney disease (CKD), common non-communicable diseases and methicillin resistant Staphylococcus aureus (MRSA) colonization. Albumin creatinine ratio > 30 mg/g urine taken as cut-off for detection of CKD.
RESULTS: Screened 417 soldiers, all were men and body mass index were 21.4 ± 2.2 kg/m2. They smoke 0.5 ± 0.1 pack years while consume alcohol 32 ± 3 units/week and were having 100/min average daily moderate physical activity. Eight of them (0.2%) were having essential hypertension, 4 (0.1%) of them were having diabetes mellitus. Blood cholesterol was within normal range. CKD unknown etiology (CKDu) prevalence among screened army soldiers was 0.009. All were from native army recruits. Further, 71.2% had MRSA colonization. In a group of middle aged army recruits, despite tobacco smoking and moderate level of alcohol consumption while continuously having healthy dietary practices with physical activities would leads to low prevalence of communicable diseases. Further, compared to native group of solders, visitors but living long time recruits CKDu incidence is zero.

Interactions of zearalenone and its reduced metabolites α-zearalenol and β-zearalenol with serum albumins: species differences, binding sites, and thermodynamics
Abstract
Zearalenone (ZEN) is a mycotoxin produced by Fusarium species. ZEN mainly appears in cereals and related foodstuffs, causing reproductive disorders in animals, due to its xenoestrogenic effects. The main reduced metabolites of ZEN are α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL). Similarly to ZEN, ZELs can also activate estrogen receptors; moreover, α-ZEL is the most potent endocrine disruptor among these three compounds. Serum albumin is the most abundant plasma protein in the circulation; it affects the tissue distribution and elimination of several drugs and xenobiotics. Although ZEN binds to albumin with high affinity, albumin-binding of α-ZEL and β-ZEL has not been investigated. In this study, the complex formation of ZEN, α-ZEL, and β-ZEL with human (HSA), bovine (BSA), porcine (PSA), and rat serum albumins (RSA) was investigated by fluorescence spectroscopy, affinity chromatography, thermodynamic studies, and molecular modeling. Our main observations are as follows: (1) ZEN binds with higher affinity to albumins than α-ZEL and β-ZEL. (2) The low binding affinity of β-ZEL toward albumin may result from its different binding position or binding site. (3) The binding constants of the mycotoxin-albumin complexes significantly vary with the species. (4) From the thermodynamic point of view, the formation of ZEN-HSA and ZEN-RSA complexes are similar, while the formation of ZEN-BSA and ZEN-PSA complexes are markedly different. These results suggest that the toxicological relevance of ZEN-albumin and ZEL-albumin interactions may also be species-dependent.

Closing the Gap: Understanding African-American Asthma Knowledge and Beliefs
Asthma remains a common and serious public health problem affecting 24 million people in the United States (US). The disease accounts for 1.6 million emergency department visits and 10.5 million physician's office visits each year in the US [3]. Asthma prevalence rates are higher among specific populations such as children, females, ethnic minorities, and those living below the poverty level; many of these groups also have higher rates of asthma related morbidity and mortality [4]. African-Americans with asthma experience disproportionate rates of morbidity and mortality compared to Caucasians [5].

Resolution of Eosinophilia and Elevated Immunoglobulin E with Ibrutinib for Chronic Lymphocytic Leukemia
Eosinophilia can be categorized as mild (500-1500 eosinophils/µL), moderate (1500-5000 eosinophils/µL), or severe (≥5000 eosinophils/µL) with hypereosinophilia referring to an eosinophil count ≥1500 eosinophils/µL.1 Rarely, eosinophilia is associated with hematologic disorders that produce eosinophilopoietic cytokines.2 We describe a case of eosinophilia and elevated IgE in a 61-year-old gentleman who was subsequently diagnosed with B-cell chronic lymphocytic leukemia (B-CLL). His eosinophilia and immunoglobulin E (IgE) levels declined significantly after initiating ibrutinib therapy for B-CLL.

Moisturizers vs. Barrier Repair in the Management of Atopic Dermatitis
Current guidelines recommend the use of anti-inflammatory agents along with moisturizers for the management of atopic dermatitis (AD).1 This approach is prudent, since co-applications of moisturizers under nursing supervision reduce reliance upon topical steroids in AD management.2,3 Yet, some commonly employed moisturizers could harm the skin, if deployed in settings where the barrier already is compromised,3 as in AD. Here, we will compare the key differences between ubiquitous, over-the-counter moisturizers and preparations formulated specifically to correct the biochemical abnormalities in AD.

Response to YAJOT_2018_288 “Letter to the Editor: T2-weighted MRI screening algorithm for patients with asymmetric sensorineural hearing loss”
We thank Drs. O'Bryant and Woo for their thoughtful commentary on our recent publication. We agree that any screening protocol for vestibular schwannoma (VS) or intralabyrinthine schwannoma (ILS) must heavily prioritize asymmetric audiovestibular findings in order to reduce the risk of not scanning a patient with a tumor and scanning too many patients that do not have a lesion. In addition, thin slice image acquisition is critical to identify small, often subtle intracanalicular and intralabyrinthine lesions.

T2-weighted MRI screening algorithm for patients with asymmetric sensorineural hearing loss
We read with interest the article by Valesano et al. [1]. As noted in the article, gadolinium-enhanced T1-weighted MRI (GdT1WI) has been the "gold standard" imaging study for many years in the diagnosis of vestibular schwannoma in asymmetric sensorineural hearing loss (ASNHL). In recent years, with improved imaging technology, a push toward non-contrast T2-weighted MRI (T2WI) for screening of patients with ASNHL has been made in an effort to decrease patient exposure to gadolinium, acquisition time, and cost.

How does sleep restriction therapy for insomnia work? A systematic review of mechanistic evidence and the introduction of the Triple-R model
For over 30 years sleep restriction therapy (SRT) has been used to treat insomnia but we know very little about how this therapy exerts its effects. When SRT was first described, it was hypothesised to treat insomnia by addressing four key factors: strengthening homeostatic sleep pressure, inhibiting perpetuating practices (excessive time in bed), attenuating hyperarousal and tightening regulatory control of sleep by the endogenous circadian pacemaker. We conducted a systematic literature review in search of evidence for these putative mechanisms-of-action.

Office-Based Procedures for Nasal Airway Obstruction
Treatment of common rhinologic problems with in-office surgical procedures has increased dramatically in response to patient preference, evolving insurance patterns, and changes in coding and reimbursement. Because this is an emerging practice, there is not a lot of evidence published about how to best perform these techniques. This article provides practical advice from experienced surgeons related to logistics and anesthetic techniques for conducting in-office surgical treatment of nasal airway obstruction; an overview of office set-up and necessary equipment; and specific procedural considerations. Attention also is paid to pharmacologic issues. Logistics and clinical considerations for common office-based procedures for obstructive pathology are reviewed.

The fermented product was obtained by the fermentation process of the aerial part of O. sanctum. Total soluble protein was detected in the fermented product with the amount of 65.32 ± 0.14 mg/100 mL, whereas there was no organic acid. The inhibitory activity against four strains of M. furfur (No. 133, 656, 6000, and 7966) of the fermented product and shampoos containing the fermented product were investigated by broth dilution and agar diffusion method, respectively. The fermented product possessed high antifungal activity with the minimum inhibitory concentrations for 50% (MIC50) of M. furfur 133, 656, 6000, and 7966 of 0.125, 0.25, 0.125, and 0.125 mg/mL, respectively. Interestingly, the antifungal activity against M. furfur 656 was comparable to that of ketoconazole. Shampoo formulation C, which was the best formulation in terms of characteristics and stability, obtained a high level of satisfaction scores in terms of hair smoothness, hair shine, ease in combing, frizz reduction, and triboelectric reduction while brushing. Additionally, the shampoo containing 2% (w/w) of the fermented product of O. sanctum also possessed inhibitory activity against M. furfur 133, 656, 6000, and 7966 with inhibition zones of 13.2 ± 1.6, 12.8 ± 1.1, 18.7 ± 0.3, and 17.0 ± 1.1 mm respectively. Therefore, this shampoo was suggested for use as an antidandruff shampoo.

A Rare Case of Vascular Leiomyosarcoma Originating from a Branch Vessel of the External Iliac Vein
Leiomyosarcoma arising from the external iliac vein is uncommon. This is a report of a 51-year-old Japanese man with venous leiomyosarcoma originating from a branch vessel of the left external iliac vein. The tumor was found during a medical examination, and the patient had no symptoms. Computed tomography showed a 72 × 49 mm mass adjacent to the left external iliac vein. The tumor was resected en-block along with ligation of the external iliac vein due to strong adhesion with the tumor. Histological examination showed venous leiomyosarcoma, and its origin was thought to be a branch vessel of the left external iliac vein. The patient has remained free from recurrence at 30 months after surgery.
