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.

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.

Neutrophil extracellular traps in the pathogenesis of chronic rhinosinusitis

xlomafota13 shared this article with you from Inoreader Neutrophil extracellular traps in the pathogenesis of chronic rhinosinusitis Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(6):105-112. doi: 10.17116/otorino202186061105. ABSTRACT The review presents the current understanding of the pathogenesis of chronic rhinosinusitis. The causes of damage to the mucous membrane of the paranasal sinuses are most often the result of a combination of immunological, infectious and anatomical factors. This indicates the need for a multidisciplinary approach to the study of the pathogenesis of this pathology. There is no single universally recognized classification of chronic rhinosinusitis, which takes into account histological and immunological changes in the mucous membrane of the paranasal sinuses. The discovery of the mechanism of completion of the life cycle of neutrophils - the formation of a neutrophil extracellular trap or NETosis, different from necrosis and apoptosis, opened up new prospects in the study of the pathogenesis of inflammatory processes, including rhinosinusitis. Neutroph il extracellular traps reduce the permeability of the epithelial barrier in the mucous membrane of the paranasal sinuses. This determines their possible role in the etiopathogenesis of rhinosinusitis. In recent years, more and more attention has been paid to the feasibility, effectiveness and safety of therapy that affects the immune component of the inflammatory process, including NETosis. The data obtained in the study of extracellular traps can be used in clinical practice. It is neutrophil extracellular traps that can become a potential target in the treatment of patients with chronic rhinosinusitis.

Laryngeal cysts in children

xlomafota13 shared this article with you from Inoreader Laryngeal cysts in children Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(6):57-61. doi: 10.17116/otorino20218606157. ABSTRACT Laryngeal cysts in children are relatively rare, occupying the 4-5th place in the structure of congenital malformations. The paper presents the combined experience of two Russian pediatric otorhinolaryngological clinics traditionally involved in the rehabilitation of patients with congenital and acquired pathology of the larynx. OBJECTIVE: To analyze the features of the clinic, diagnosis and treatment of laryngeal cysts in children. MATERIAL AND METHODS: The study included 68 children with laryngeal cysts aged from 3 days to 16 years (on average 39.5±37.0 months, Me=15.5 months). The cyst was localized in the vestibular region of the larynx in 15 (22.1%) patients, in the vocal region - in 15 (22.1%) patients, and in the sub-vocal region - in 38 (55.9%) patients. Data on the presence of a history of tracheal intubation were available in 35 ( 89.7%) children, including 35 (92.1%) of 38 children with a subfold cyst. 11 patients were admitted with a previously applied tracheostomy. RESULTS: The main reasons for going to the clinic were signs of laryngeal stenosis (stridor, signs of obstruction of the upper airways) in 60.3% of patients, dysphonia - in 33.8%, and in 5.9%, the detection of a cyst became an accidental finding. To eliminate the cyst, the method of laser marsupialization was used in 10 patients, coagulatory ablation - in 2 patients, in the remaining 56 patients, decortication was performed with microinstruments, followed by laser treatment of the cyst bed. In the follow-up, children were traced from 6 months to 7 years. We did not observe a recurrence of a cyst in any case. CONCLUSION: Currently, the lining department is the "favorite" localization of the cyst in childhood. Subclavian cysts are more common in preterm infants who need tracheal intubation. A necessary condition for radical elimination is the resection of the cyst walls. PMID:34964331 | DOI:10.17116/otorino20218606157 View on the web Inoreader. Take back control of your news feed.

Reversible Iodine Capture by Nonporous Adaptive Crystals of a Bipyridine Cage

xlomafota13 shared this article with you from Inoreader Reversible Iodine Capture by Nonporous Adaptive Crystals of a Bipyridine Cage Via radioactive iodine J Am Chem Soc. 2021 Dec 28. doi: 10.1021/jacs.1c11731. Online ahead of print. ABSTRACT The ability to capture radioactive iodine species is crucial for nuclear accident preparedness and nuclear waste treatment; however, it remains a challenge. Here we report a new readily obtainable nitrogen-rich nonporous cage (BPy-Cage) based on bipyridine building blocks that supports iodine capture. This cage is able to capture not only volatile iodine in vapor form but also iodine disso lved in various organic solvents or aqueous media with an iodine uptake capacity of up to 3.23 g g-1. The iodine within the cage (I2@BPy-Cage) can be released quickly upon immersing the bound solid form in DMF, allowing for control over acylation reactions. The cage solids reported here could be reused several times without substantial loss in their iodine capture performance. The effectiveness of the present system is ascribed to its ability to support strong iodine-bipyridine nitrogen lone pair interactions.
