Online ahead of print. ABSTRACT INTRODUCTION: Several methods of controlling pain post-bilateral breast augmentation (BBA) have been described. BBA is frequently performed as a day case procedure; therefore, a simple effective method of controlling pain in the immediate post-operative period is desired. METHODS: We conducted a prospective, double-blinded, placebo-controlled randomised study of 20 women undergoing BBA. Women were randomly assigned to receive intraparenchymal infiltration intra-operatively prior to implant placement with either local anaesthetic (LA) (chirocaine) or normal saline. The primary outcome was post-operative pain scores immediately, and at 6 h. Our secondary endpoint was post-operative narcotic consumption. RESULTS: Twenty patients were included in this study. The average pain score in the immediate po st-operative period was 3.4 in the control group versus 0.7 in the treatment group (p = 0.013). In 6 h post-operatively, the average pain score was 2.4 in the control group versus 0.9 in the treatment group (p = 0.03). Sixty-six percentage of patients in the control arm required post-operative opiates compared with 27% in the treatment group (p = 0.17) CONCLUSION: This randomised controlled trial demonstrates a technique of intraparenchymal infiltration of LA that significantly reduces post-operative pain scores after BBA.

Surgical risk prediction for nasolacrimal duct obstruction in radioactive iodine treated thyroid cancer: A nationwide cohort study

xlomafota13 shared this article with you from Inoreader Surgical risk prediction for nasolacrimal duct obstruction in radioactive iodine treated thyroid cancer: A nationwide cohort study Via radioactive iodine Thyroid. 2021 Dec 12. doi: 10.1089/thy.2021.0418. Online ahead of print. ABSTRACT BACKGROUND: To estimate the incident risk of surgical intervention for nasolacrimal duct obstruction after radioactive iodine (RAI) treatment and elucidate the high-risk group of patients with thyroid cancer (TC). METHODS: This is a nationwide, population-based, cohort study using data from the Korean National Health Claims database. Among the entire South Korean population aged between 20 and 8 0 years from 2007 to 2019, all patients with TC were included. Among all TC patients, a cohort was established by classifying it into the RAI and non-RAI groups according to whether RAI treatment was performed during the recruitment period. A log-rank analysis was used to evaluate the risk of nasolacrimal duct obstruction surgery in the RAI group compared to that in the non-RAI group. The cox proportional hazards regression analysis was performed to calculate the adjusted hazard ratio (HR). The analysis was performed stratified by the age group, sex, frequency of RAI treatment, and cumulative dose of I131. RESULTS: Among 55371 TC patients, who received RAI treatment, 515 (0.93%) underwent NLDO surgeries, and among 56950 TC patients, who did not receive RAI treatment, 72 (0.13%) underwent the surgeries. The average timing of incident nasolacrimal duct obstruction surgery was 3.8 ± 2.1 years after the first exposure to RAI. The incidence rate of nasolacrimal duct obstruction su rgery was 104.04/100000 person-years in the RAI group. There was a significantly higher risk of nasolacrimal duct obstruction surgery (HR 7.50, 95% confidence interval [CI]: 5.86-9.60, p < 0.001) in the RAI group than in the non-RAI group. The risks significantly increased in the high-dose group (HR 14.15, 95% CI: 10.88-18.39) and those younger than 50 years (HR 15.54, 95% CI: 9.76-24.72). CONCLUSION: We quantified the risk of RAI-induced nasolacrimal duct obstruction surgery through a long-term follow-up of 9 years, which may contribute to estimating the general health care burden related to RAI treatment for TC patients in a practical setting. Great attention should be paid to its risk in patients younger than 50 years, especially in those treated with high doses. PMID:34894720 | DOI:10.1089/thy.2021.0418 View on the web Inoreader.

Differentialdiagnostik intraorbitaler Raumforderungen – eine Übersicht

xlomafota13 shared this article with you from Inoreader Differentialdiagnostik intraorbitaler Raumforderungen – eine Übersicht Via Laryngo-Rhino-Otologie Laryngorhinootologie DOI: 10.1055/a-1580-7371 Hintergrund Aufgrund der unmittelbaren Nähe zum visuellen System stellen intraorbitale Raumforderungen eine Bedrohung für den Patienten und eine besondere Herausforderung für jede in Diagnostik und Therapie involvierte Fachdisziplin dar. Material/Methoden Narratives Review mit Diskussion von relevanten Originalarbeiten und Expertenempfehlungen. Zur Veranschaulichung beschreiben wir den Fall eines 71-jährigen Patienten, der 3 Monate nach einer Nasennebenhöhlenoperation in unserer Abteilung aufgenommen wurde. Ein postoperatives intraorbitales Hämatom der rechten Orbita war extern konservativ mit Antibiotika/Kortikosteroiden behandelt worden, was zu einem nahezu vollständigen einseitigen Sehverlust geführt hatte. Die folglich durchgeführte Orbita- und Optikusdekompression verhinderte nicht die Bildung eines intraorbitalen Lipogranuloms. Gegenwärtig werden die damit verbundenen rezidivierenden Entzündungsphasen erfolgreich konservativ auf der Grundlage multidisziplinärer Empfehlungen behandelt. Ergebnisse In dem berichteten Fall mündete eine verzögerte Orbita- und Optikusdekompression bei retrobulbärem Hämatom nach Nasennebenhöhlenoperation in der Bildung eines intraorbitalen Lipogranuloms. Die Literatur unterstützt unsere Empfehlung einer sofortigen chirurgischen Intervention im Falle eines akuten retrobulbären Hämatoms. Neben akuten Zuständen können intraorbitale Raumforderungen Zeichen systemischer Erkrankungen sein. In jedem Fall ist ein multidisziplinärer Therapieansatz für ein adäquates Management erforderlich. Schlussfolgerung Intraorbitale Raumforderungen können u.a. als akute Komplikation nach Nasennebenhöhlenoperationen auftreten oder Zeichen maligner Entartung und chronischer Erkrankungen sein. Differenzialdiagnostische Kenntnisse zu intraorbitalen Raumforderungen sind daher für jede im Kopf-Hals-Bereich tätige Fachdisziplin unerlässlich.

PD-1 Inhibitor Maintenance Therapy Combined Iodine-125 Seed Implantation Successfully Salvage Recurrent Cervical Cancer after CCRT: A Case Report

xlomafota13 shared this article with you from Inoreader PD-1 Inhibitor Maintenance Therapy Combined Iodine-125 Seed Implantation Successfully Salvage Recurrent Cervical Cancer after CCRT: A Case Report Via radioactive iodine Curr Oncol. 2021 Nov 9;28(6):4577-4586. doi: 10.3390/curroncol28060387. ABSTRACT Cervical cancer is the fourth most common cancer in females worldwide. Patients with stage III and IV cervical cancer based on the Federation of Gynecology and Obstetrics (FIGO) classification have higher recurrence rates. Because of organs at risk (OAR) protection and the low indication rate of salvage surgery, the choice of treatment is always challenging. Systemic chemotherapy is palliative and can be performed in conjunction with surgery or radiotherapy; however, it has no significant benefit to survival. Brachytherapy and stereotactic body radiotherapy (SBRT) are characterized by extremely high radiation doses applied to tumor cells while sparing the normal tissues. Several studies have investigated the efficacy of these technologies in recurrent cervical cancer and showed promising results. The immune checkpoint inhibitors approach was also investigated and showed promising results too. Herein, we report a case of a patient with cervical cancer that recurred five months after adjuvant chemotherapy and concurrent chemoradiotherapy. The disease prognosis after interstitial implantation brachytherapy (IIB) was determined. Then, the patient underwent radioactive 125I-seed implantation combined with PD-1 inhibitor treatment. The patient exhibited a partial response after seed implantation, and up to now, the duration of this partial response was 24 months.

Association of MIF gene polymorphisms with pemphigus vulgaris: a case-control study with comprehensive review of the literature

xlomafota13 shared this article with you from Inoreader Association of <em>MIF</em> gene polymorphisms with pemphigus vulgaris: a case-control study with comprehensive review of the literature Via International Journal of Clinical and Experimental Pathology Int J Clin Exp Pathol. 2021 Nov 15;14(11):1080-1089. eCollection 2021. ABSTRACT BACKGROUND: Functional macrophage migration inhibitory factor (MIF) gene polymorphisms are associated with elevated serum levels of MIF and increased susceptibility to various autoimmune diseases. MIF levels in the sera of pemphigus vulgaris (PV) patients are increased; however, no definite association has been demonstrated between PV and MIF gene polymorphisms. The present study was conducted to ascertain any association between MIF-173*G-C and MIF-794*CATT5-8 polymorphisms and PV. METHODS: Seventy-five patients with PV and 252 healthy, unrelated, voluntary controls were enrolled randomly in the study. MIF-173*G-C polymorphism (rs755622) was genotyped using polymerase chain reaction (PCR) followed by restriction fragment length analysis, and MIF-794*CATT5-8 (rs5844572) was genotyp ed using PCR followed by capillary gel electrophoresis. Subsequently, the allelic, genotype, and haplotype frequencies were determined and compared for both groups. Data were also analyzed with respect to sex, age at onset, type of disease, and duration of disease. RESULTS: No significant association was observed in terms of allelic, genotype, and haplotype frequencies of MIF gene polymorphisms in PV patients. However, a significantly lower prevalence of the C allele (P=0.02) and CATT7 allele (P=0.03) was seen in our patient population compared to healthy controls. Analysis of the effect of various factors such as gender, age at onset, type of disease, and disease duration revealed no significant association with the genetic variants. CONCLUSIONS: MIF-173*G-C and -794*CATT5-8 polymorphisms are not associated with PV. PMID:34900076 | PMC:PMC8661066 View on the web Inoreader. Take back control of your news feed.

Chromophobe renal cell carcinoma-like thyroid carcinoma: possible misdiagnosis as metastatic renal cell carcinoma

xlomafota13 shared this article with you from Inoreader Chromophobe renal cell carcinoma-like thyroid carcinoma: possible misdiagnosis as metastatic renal cell carcinoma Via International Journal of Clinical and Experimental Pathology Int J Clin Exp Pathol. 2021 Nov 15;14(11):1095-1101. eCollection 2021. ABSTRACT To date, multiple thyroid cancer variants have been reported. Herein, we report a rare case of chromophobe renal cell carcinoma-like thyroid carcinoma (CRETHCA) in a 60-year-old woman, for which the morphologic findings resembled those of chromophobe renal cell carcinoma (ChRCC). ChRCC of the kidney is characterized by large polygonal tumor cells with distinct cell borders, perinuclear clearing, multiple binucleate cells, and strongly positive immunostaining for paired box gene 8 (PAX8) and carbonic anhydrase IX (CA IX). In our case, the thyroid gland tumor was incidentally detected by routine medical screening without sufficient medical information; it showed similar histology and immunohistochemical features to ChRCC and was initially misdiagnosed as metastatic ChRCC. Additional tests, including kidney computed tomography and positron emission tomography, revealed no abnormalities in the patient's kidney; therefore, we diagnosed the tumor as CRETHCA. Focal weak staining for thyroid transcription factor 1 (TTF-1) was the only supporting evidence that it was a primary thyroid neoplasm. To the best of our knowledge, this is the second report of CRETHCA in literature. This novel variant is very difficult to distinguish from metastatic ChRCC and can be a diagnostic challenge for pathologists. Further studies of similar cases should be done to define this new entity. PMID:34900078 | PMC:PMC8661068 View on the web Inoreader. Take back control of your news feed.

Upregulation of TLR9 may contribute to activation of microglia and painful diabetic neuropathy via the p38 MAPK pathway in rats

xlomafota13 shared this article with you from Inoreader Upregulation of TLR9 may contribute to activation of microglia and painful diabetic neuropathy via the p38 MAPK pathway in rats Via Cellular and Molecular Biology Histol Histopathol. 2021 Dec 10:18405. doi: 10.14670/HH-18-405. Online ahead of print. ABSTRACT Painful diabetic neuropathy is a common chronic complication of diabetes, and the underlying mechanism remains largely elusive. A rat model of painful diabetic neuropathy was established via streptozotocin (STZ) injection and assessed as increased heat and mechanical hypersensitivity. An upregulation of TLR9 was observed in the spinal cords of rats injected with STZ and rat microglia (primary microglia and immortalized microglia HAPI) treated with high glucose. To investigate the role of TLR9 in high glucose-induced microglia activation, short hairpin RNAs targeting TLR9 were used in vitro to knock down TLR9 in HAPI cells. TLR9 interference suppressed the high glucose-induced expression and secretion of inflammatory cytokines (TNF-α, IL-1β, and IL-6), IBA-1 expression and the chemotaxis of HAPI microglia. Similar results were obtained when HAPI microglia were incubated with a p38 inhibitor (SB203580). P38 and ERK were downstream of TLR9 because TLR9 ablation markedly inhibited the phosphorylation of p38 and ERK. TLR9 was also knocked down in vivo via the injection of shTLR9 lentiviral vector into the rat spinal cord. Relief of STZ-induced heat and mechanical hypersensitivity was observed in rats with TLR9 interference, and TLR9 knockdown prevented STZ-induced inflammatory cytokine secretion and microglial and MAPK signaling activation. Our study revealed the participation of TLR9 in microglial activation and diabetes-induced hyperalgesia likely via the MAPK pathway. The targeting of TLR9 may be an effective strategy for the treatment of painful diabetic neuropathy. PMID:34889455 | DOI:10.14670/HH-18-405 View on the web Inoreader.
