Online ahead of print. ABSTRACT BACKGROUND: In view of the poor prognosis and high mortality of cholangiocarcinoma, there is a need for new therapeutic strategies. This study aims to reveal the biological function of miR-146b-5p in cholangiocarcinoma cell and its possible mechanism. METHODS: The expression level and prognostic information on miR-146b-5p in cholangiocarcinoma were obtained in T CGA database. The biological function of miR-146b-5p on proliferation and vitality of cholangiocarcinoma cell HUCCT-1 was examined by EdU and MTT assay, and the apoptosis of HUCCT-1 cells transfected with miR-146b-5p mimic, mimic control, inhibitor, inhibitor control was detected by flow cytometry analysis. The western blot was done to evaluate the effect of miR-146b-5p targeting substrate and the expression of p53 in whole-cell protein and mitochondria fractions. RESULTS: Our finding revealed that miR-146b-5p expression in patients with CHOL was lower than the normal group(p＜0.001). MiR-146b-5p expression was down-regulated in human cholangiocarcinoma HUCCT-1 and RBE cells compared to normal control HIBEC and other cancer cells. The miR-146b-5p mimic could inhibit HUCCT-1 cell proliferation (p＜0.05) and promote HUCCT-1 cell apoptosis significantly (p＜0.05). The results of western blot showed that miR-146b-5p mimic could directly target TRAF6 3'UTR region and up-regulate the expression of p53 in mitochondria and miR-146b-5p inhibitor could down-regulated the level of p53 in mitochondria. CONCLUSION: MiR-146b-5p is a cholangiocarcinoma suppressor by inhibiting cell proliferation and promoting cell apoptosis with targeting TRAF6, possibly via modulating p53 translocation to mitochondria.

xlomafota13 shared this article with you from Inoreader Effects of Dental Factors on Fungal Sinusitis Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Objectives: This study aimed to investigate the associations between dental treatments and fungal maxillary sinusitis (FMS). Methods: We retrospectively reviewed medical charts between July 2014 and March 2019. In total, 100 cases of FMS were included in this study. We also recruited 200 patients as a control group in the same period. Therefore, each of the FMS, chronic rhinosinusitis (CRS), and normal sinus groups consisted of 100 patients. We recorded all endodontic treatments (EDTs), tooth extractions, dental implantations, and ap ical lesions (ALs). Results: The FMS group had higher incidences of tooth extraction (49% vs. 11%, respectively) and EDT (29% vs. 16%, respectively) compared to the normal sinus group and fewer ALs compared to the CRS group (6% vs. 24%, respectively). There were significant differences between the CRS and normal sinus groups in the extraction rate (53% vs. 11%, respectively) and frequency of ALs (24% vs. 4%, respectively). The dental implantation prevalence rates were similar across all 3 groups. Conclusion: The rates of tooth extraction were significantly higher in the FMS and CRS groups compared to the normal sinus group. In addition, of the 3 conditions, FMS was related to EDT, and CRS was related to ALs. ORL View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Arnold Kirkpatrick Henry (1886-1962) and his eponym (Master Knot of Henry): a narrative review

xlomafota13 shared this article with you from Inoreader Arnold Kirkpatrick Henry (1886-1962) and his eponym (Master Knot of Henry): a narrative review Via radiol anat Surg Radiol Anat. 2021 Oct 5. doi: 10.1007/s00276-021-02847-x. Online ahead of print. ABSTRACT PURPOSE: The aims of this review were to form a more precise description for Master Knot of Henry (MKH), and to modify classifications related to interconnections between flexor hallucis longus (FHL) and flexor digitorum longus (FDL) for showing all configurations in the literature. METHODS: A literature search was performed in main databases to obtain information related to anatomical definitions and variations of MKH. The search was carried out using the following keywords: "Master Knot of Henry", "Chiasma plantare", "Flexor hallucis longus" and "Flexor digitorum longus". Information extracted from the studies was: sample size, numerical values, classifications, variation types, incidence of types, anatomical definitions of MKH, year of publication, and type of study. RESULTS: This study proposes that MKH should be defined as the intersection territory where FDL crosses over FHL in the plantar foot. The postchiasmatic plantar area located at distal to MKH (the narrow space between MKH and the division of FDL) should be termed as the triangle of Henry. Moreover, the classification systems showing different configurations related to interconnections situated at Henry's triangle were updated as eight types to present all forms in the literature. CONCLUSION: Our definitions may assist in determining the precise anatomical boundaries of MKH, an d thus facilitate the use of MKH as a surgical landmark. In addition, our modified classification systems covering all variations in the current literature may be helpful for surgeons and anatomists to understand formations of the triangle of Henry, and the long flexor tendons of the lesser toes.

Putting the Pieces Together: the Hair Cell Transduction Complex

xlomafota13 shared this article with you from Inoreader Putting the Pieces Together: the Hair Cell Transduction Complex Via Journal of the Association for Research in Otolaryngology Abstract Identification of the components of the mechanosensory transduction complex in hair cells has been a major research interest for many auditory and vestibular scientists and has attracted attention from outside the field. The past two decades have witnessed a number of significant advances with emergence of compelling evidence implicating at least a dozen distinct molecular components of the transduction machinery. Yet, how the pieces of this ensemble fit together and function in harmony to enable the senses of hearing and balance has not been clarified. The goal of this review is to summarize a 2021 symposium presented at the annual mid-winter meeting of the Association for Research in Otolaryngology. The symposium brought together the latest insights from within and beyond the field to examine individual components of the transduction complex and how these elements interact at molecular, structural, and biophysical levels to gate mechanosensitive channels and in itiate sensory transduction in the inner ear. The review includes a brief historical background to set the stage for topics to follow that focus on structure, properties, and interactions of proteins such as CDH23, PCDH15, LHFPL5, TMIE, TMC1/2, and CIB2/3. We aim to present the diversity of ideas in this field and highlight emerging theories and concepts. This review will not only provide readers with a deeper appreciation of the components of the transduction apparatus and how they function together, but also bring to light areas of broad agreement, areas of scientific controversy, and opportunities for future scientific discovery.

Parathyroid Gland Autofluorescence Characteristics in Patients With Primary Hyperparathyroidism

xlomafota13 shared this article with you from Inoreader Parathyroid Gland Autofluorescence Characteristics in Patients With Primary Hyperparathyroidism Via The Laryngoscope Objective Near-infrared imaging for intraoperative parathyroid gland (PG) detection has recently commanded significant attention. The PTeye (Medtronic, Minneapolis, MN) is a probe-based system for near-infrared autofluorescent evaluation of PGs. This study was designed to evaluate the capabilities of the PTeye in the setting of surgery for primary hyperparathyroidism. Study Design Prospective, Cohort study. Methods This single-institution, prospective cohort study included all patients undergoing parathyroidectomy for primary hyperparathyroidism with presumed single gland disease from June 2020 to December 2020. Absolute intensity and intensity ratios, with the thyroid as the control tissue, were obtained for the adenoma, ipsilateral normal PG, and adjacent tissue. The ability of the PTeye to function when not in direct contact with tissue was measured. Results Twenty-two patients were included. The median intensity ratio for the in situ adenomas was 4.38 (interquartile range [IQR]: 2.03–5.87), ipsilateral normal PGs 6.17 (IQR: 3.83–7.67), strap muscle 0.47 (IQR: 0.30–0.60), and fat 0.20 (IQR: 0.17–0.47). All normal PGs and 21/22 adenomas demonstrated autofluorescence above the detection threshold. The PTeye functioned at a maximum distance of separation of 10 mm through saline medium and 6 mm through clear solid medium. Conclusion This study confirms the PTeye's ability to recognize PGs with a high degree of precision. The device was found to function properly even with the probe not in direct contact with the tissue. Although adenomatous PGs appear to demonstrate altered autofluorescent properties from normal PGs, additional research is required to determine if these differences are clinically useful.

The Long-term Effect of Inferior Turbinate Surgery Techniques on Nasal Obstruction and Quality of Life

xlomafota13 shared this article with you from Inoreader The Long-term Effect of Inferior Turbinate Surgery Techniques on Nasal Obstruction and Quality of Life Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Oct 6:34894211049573. doi: 10.1177/00034894211049573. Online ahead of print. ABSTRACT OBJECTIVE: The aim of the study was to compare the long-term effects of radiofrequency ablation (RFA), microdebrider-assisted inferior turbinoplasty (MAIT), and diode laser techniques on the severity of nasal obstruction and quality of life (QOL) in a 3-year follow-up. METHODS: The patients filled a Visual Analog Scale (VAS) regarding the severity of nas al obstruction and the Glasgow Health Status Inventory (GHSI) questionnaire preoperatively and during the control visits at 3 months and 3 years. Acoustic rhinometry was also performed. A total of 78 patients attended both control visits. RESULTS: All 3 techniques improved the VAS score for the severity of nasal obstruction and the GHSI total score significantly compared to the preoperative values at both 3 months and 3 years. Compared to the preoperative values, all 3 techniques increased the V2 to 5 cm values significantly at 3 months. After 3 years, compared to the preoperative values, the MAIT (P = .005) and diode laser (P < .001) still had a statistically significant volume increase in V2 to 5 cm, whereas the RFA (P = .06) did not achieve a statistically significant effect. CONCLUSION: The RFA, MAIT, and diode laser all improved both the patients' subjective sensation of the severity of nasal obstruction and QOL significantly. The response wa s sustained during the 3-year follow-up period with all 3 techniques. A weakening in the objective treatment response to RFA was found in the longer follow-up, but that did not cause a weakening of the patients' subjective treatment response.

Impact of Preoperative Steroids Administration on Endoscopic Sinus Surgery: Systematic Review of Literature, and a Survey in Saudi Arabia

xlomafota13 shared this article with you from Inoreader Impact of Preoperative Steroids Administration on Endoscopic Sinus Surgery: Systematic Review of Literature, and a Survey in Saudi Arabia Via Otolaryngology Indian Abstract There is limited knowledge in the literature and lack of clear protocols among practitioners regarding preoperative steroids administration for patients undergoing endoscopic sinus surgery (ESS). This study aimed to identify the practice patterns of rhinologists in Saudi Arabia as well as systematically review all health-related evidence regarding the use of preoperative steroids for ESS. A previously used questionnaire was modified and distributed in Saudi Arabia among rhinologists who finished their residency training. It entailed questions about their qualifications and preoperative steroids use, preferred regimen, and possible benefits. Also, a systematic literature review using four major databases was conducted to build a scoping view of the current evidence. A total of 94 subjects responded to the mailed survey. Of them, 72(76.6%) used preoperative steroids; 40 subjects believed that there is a strong supporting evidence while 32 reported that there is no solid evidence. The commonest indication was chronic rhinosinusitis with nasal polyp followed by allergic fungal rhinosinusitis. More than half of subjects (54.2%) preferred medium-dose prednisone (30–40 mg/day). A considerable number believed that steroids decreased surgical bleeding (n = 57, 79.2%), improved surgical field visualization (77.8%), decreased surgical time (77.8%), and decreased mucosal inflammation (61.1%). Thirteen studies including 1028 patients were eligible for the systematic review. Only three studies reported a statistically significant effect of steroids in reducing intraoperative hemorrhage, while only two studies revealed that steroids significantly improved surgical field quality. In two studies, steroids showed a significant effect in reducing eosinophil infiltration. There is a major number of rhinology experts using preoperative steroids for patients undergoing ESS but there is a wide variation among their practice patterns. The current potent ial advantages of steroids need to be supported by further large randomized clinical trials to establish clear guidelines. View on the web Inoreader.

Loupe Assisted Thyroidectomy: A Tool for Reducing Complications

xlomafota13 shared this article with you from Inoreader Loupe Assisted Thyroidectomy: A Tool for Reducing Complications Via Otolaryngology Indian Abstract The objective of this study is to assess if the use of magnification can reduce the incidence of hypocalcemia and vocal cord palsy in thyroid surgery. Data of patients who underwent total thyroidectomy (N = 50) for thyroid malignancy were analyzed retrospectively for 1 year. The patients were divided into two groups based on surgery with and without loupes. Hypocalcemia and Vocal cord palsy was assessed pre as well as post-operatively and the observations were noted. Descriptive statistics were performed to assess the proportion of the respective groups. Inferential statistics to find out the difference between the groups was done using the chi-square test. Significance level was kept at 5%. The incidence of hypocalcemia was 36.9% in the group done without loupes compared to 7.6% with loupes. The event of vocal cord injury though transient was 33% when done without loupes (p < 0.05). Magnification is crucial for the visualization of the n eurovascular anatomy which is depicted in our study. Although the study includes less number of cases, it is evident that the use of loupe magnification can reduce the morbidity associated with thyroid surgery to a great extent. We recommend the use of loupe magnification during surgery whenever possible. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
