Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0041-1741112 Objectives Dispersion of bone dust in the posterior fossa during retrosigmoid craniectomy for vestibular schwannoma (VS) resection could be a source of meningeal irritation and lead to development of persistent postoperative headaches (POH). We aim to determine risk factors, including whether the presence of bone spicules that influence POH after retrosigmoid VS resection. Design Present study is a retrospective case series. Setting The study was conducted at a tertiary skull-base referral center. Participants Adult patients undergoing VS resection via a retrosigmoid approach between November 2017 and February 2020 were included for this study. Main Outcome Measures Development of POH lasting ≥ 3 months is the primary outcome of this study. Results Of 64 patients undergoing surgery, 49 had complete data (mean age, 49 years; 53% female). Mean follow-up time was 2.4 years. At latest follow up, 16 (33%) had no headaches, 14 (29%) experienced headaches lasting <3 months, 19 (39%) reported POH lasting ≥3 months. Twenty-seven (55%) patients had posterior fossa bone spicules detectable on postoperative computed tomography (CT). Age, gender, body mass index, length of stay, tumor diameter, size of craniectomy, the presence of bone spicules, or the amount of posterior petrous temporal bone removed from drilling did not differ significantly between patients with POH and those without. On multivariate logistic regression, patients with POH were less likely to have preoperative brainstem compression by the tumor (odds ratio [OR] = 0.21, p = 0.028) and more likely to have higher opioid requirements during hospitalization (OR = 1.023, p = 0.045). Conclusion The presence of bone spicules in the posterior fossa on postoperative CT did not contribute to headaches following retrosigmoid craniectomy approach for VS resection.

Vesico-uterine Fistula Following C-section - A Case Report and Literature Review

xlomafota13 shared this article with you from Inoreader Vesico-uterine Fistula Following C-section - A Case Report and Literature Review Via In vivo (Athens, Greece) In Vivo. 2022 Jan-Feb;36(1):528-532. doi: 10.21873/invivo.12734. ABSTRACT BACKGROUND/AIM: Vesico-uterine fistulas represent a rare type of genito-urinary fistulas; however, due to the increasing incidence of Caesarean section (C-section) in the last decade, this abnormal communication between the urinary and genital tracts has been reported more often after such surgical procedures. The aim of the current article was to report the case of a 28-year-old patient who was submitted to surgery for a vesico-uterine fistula seven years after a C-section. CASE REPORT: The 28-year-old patient with a previous history of four vaginal deliveries and one C-section was self-presented to the Gynecology Department for cyclic hematuria and diagnosed with a vesico-uterine fistula after injecting methylene blue in the uterine cavity during hysteroscopy. The patient was further submitted to surgery, and a parcelar myometrectomy en bloc with parcelar cystectomy, cystography, and prophylactic salpingectomy was performed. The postoperative outcome was uneventful. CONCLUSION: Although vesico-uterine fistulas represent rare events, they should be considered, especially in young patients with a previous history of C-section.

Establishment and Characterization of FusionRed Stable Transfected Canine Prostate Adenocarcinoma and Transitional Cell Carcinoma Cells

xlomafota13 shared this article with you from Inoreader Establishment and Characterization of FusionRed Stable Transfected Canine Prostate Adenocarcinoma and Transitional Cell Carcinoma Cells Via In vivo (Athens, Greece) In Vivo. 2022 Jan-Feb;36(1):170-179. doi: 10.21873/invivo.12688. ABSTRACT BACKGROUND/AIM: Cancer cell inoculation is routinely used to evaluate novel therapeutic approaches in vivo. However, without reporter genes enabling deep tissue imaging, study of early tumor progression and therapeutic responses is often limited. We describe the establishment and characterization of two canine cancer cell lines stably expressing red fluorescence proteins as tools for later in vivo imaging. MATERIALS AND METHODS: Two red fluorescence cell lines were generated by plasmid transfection. Fluorescence protein expression was confirmed by flow cytometry and microscopy. Deep tissue imaging was demonstrated in mice using a NightOWL LB 983. Gene expression changes after transfection were analyzed by RNAseq. RESULTS: Both cell lines were detectable in vivo by subcutaneous injection of 1×106 cells. RNAseq revealed up to 2005 transfection-induced differentially expressed genes but no significant changes in cellular key pathways. CONCLUSION: The fluorescent cell lines provide a solid basis for future in vivo studies on canine cancer. PMID:34972712 | DOI:10.21873/invivo.12688 View on the web Inoreader.

Postoperative Inhaled Steroids Following Glottic Airway Surgery Reduces Granulation Tissue Formation

xlomafota13 shared this article with you from Inoreader Postoperative Inhaled Steroids Following Glottic Airway Surgery Reduces Granulation Tissue Formation Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Dec 30:34894211065805. doi: 10.1177/00034894211065805. Online ahead of print. ABSTRACT OBJECTIVES: Transoral laser surgery for glottic stenosis (transverse cordotomy and anteromedial arytenoidectomy (TCAMA)) is often complicated by granulation tissue (GT) formation. GT can cause dyspnea and may require surgical removal to alleviate airway obstruction. Inhaled corticosteroids (ICS) have been shown to reduce benign vocal fold granulomas, however its use to prevent GT formation has not been described. We aimed to analyze the effect of immediate postoperative ICS on GT formation in patients undergoing transoral laser surgery for glottic stenosis. METHODS: A retrospective analysis of patients that had transoral laser surgery for glottic stenosis from 2000 to 2019 was conducted. Surgical instances were grouped into those that received postoperative ICS and those that did not. Demographics, diagnosis, comorbidities, intraoperative adjuvant therapy, and perioperative medications were collected. Differences in GT formation and need for surgical removal were compared between groups. A multivariate exact logistic regression model was performed. RESULTS: Forty-four patients were included; 16 required 2 glottic airway surgeries (60 surgical instances). Of the 23 instances where patients received immediate postoperative ICS, 0 patients developed GT; and of the 37 instances that did not receive postoperative ICS, 15 (40.5%) developed GT (P < .0001). Eight (53.3%) of these cases returned to the OR for GT removal. ICS use was solely associated with the absence of GT formation (P = .042) in the multivariate analysis. CONCLUSIONS: Immediate postoperative use of ICS seems to be a safe and effective method to prevent granulation tissue formation and subsequent surgery in patients following transoral laser airway surgery for glottic stenosis.

Successful Oral Levothyroxine Desensitization in a Patient with Severe Hypothyroidism Post Radioactive Iodine Therapy: A Case Report

xlomafota13 shared this article with you from Inoreader Successful Oral Levothyroxine Desensitization in a Patient with Severe Hypothyroidism Post Radioactive Iodine Therapy: A Case Report Via radioactive iodine J ASEAN Fed Endocr Soc. 2021;36(2):213-215. doi: 10.15605/jafes.036.02.10. Epub 2021 Aug 19. ABSTRACT Levothyroxine remains the standard therapy for patients with hypothyroidism worldwide. Levothyroxine allergy is rarely seen and alternative therapies are less efficacious and scarcely available. The use of liothyronine (LT3) monotherapy is less favoured due to its short half-life and unpredictable pharmacological profile. We report a 59-year-old male with a hypersensitivity reactio n to levothyroxine who was successfully desensitized with oral levothyroxine within a day using a 14-step protocol.

Effect of dynamic balance during the onset of benign paroxysmal positional vertigo on residual dizziness after successful repositioning: a multicenter prospective cohort study

xlomafota13 shared this article with you from Inoreader Effect of dynamic balance during the onset of benign paroxysmal positional vertigo on residual dizziness after successful repositioning: a multicenter prospective cohort study Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Dec 7;56(12):1277-1282. doi: 10.3760/cma.j.cn115330-20210912-00607. ABSTRACT Objective: To explore the characteristics of dynamic balance during the onset of benign paroxysmal positional vertigo (BPPV) and its prediction of residual symptoms after successful repositioning. Methods: From January 2018 to August 2019, patients diagnosed with unilateral posterior semicircular canal or horizontal semicircular canal BPPV were consecutively enrolled from five otolaryngology clinics in Shanghai. The dynamic balance function was measured by sensory organization test (SOT) before repositioning maneuver, and the residual symptoms and its duration were followed up from one week to up to three months. Results: A total of 260 patients were recruited. After excluding 17 cases, 243 cases were successfully followed up including 89 males and 154 females, with an average age of (52. 9±13.0) years. There were 175 cases of posterior semicircular BPPV, 61 cases of horizontal semicircular BPPV and 7 cases of canal conversion (from horizontal to posterior semicircular). Among 243 patients, 118 cases reported residual symptoms, with an incidence of 48.6%. The results of SOT showed that 58.0%(141/243) of the patients had abnormal vestibular input and 41.6%(101/243) were categorized as "near falls". With respect to the detailed residual symptoms, 47 cases (39.8%) reported unsteadiness or floating, 35 cases (29.7%) had fogginess/heaviness feeling, 22 cases (18.6%) had transient dizzy while head moving, and 15 cases (12.7%) reported that the symptom was too subtle to describe. Compared with the group without residual symptoms, the group with residual symptoms had more abnormal vestibular input(χ²=67.25, P<0.001) and near falls(χ²=74.78, P<0.001) as identified by SOT test. Cox proportional hazards regression failed to reveal any SOT results having significantly impact on the duration of residual symptoms [abnormal vestibular input (HR= 0.93, 95%CI: 0.48, 1.80), and near falls (HR= 0.90, 95%CI: 0.56, 1.46)]. Kaplan-Meier survival analysis showed that there was no significant difference in the duration of residual symptoms among patients with different SOT manifestations [Log rank (Mantel-Cox) test, P>0.05]. Conclusions: The impaired dynamic balance during the onset of BPPV is characterized by "abnormal vestibular input". The residual symptoms are mainly characterized by unsteadiness or floating feeling. The defect of dynamic balance function is a predictor of the residual symptoms after successful repositioning, but not for the duration of such symptoms.
