Chronic spontaneous urticaria preceded by localized insulin reactions: case report.

Chronic spontaneous urticaria presents with wheals and/or angioedema for >6 weeks without any specific triggers. The incidence of chronic spontaneous urticaria is increased in patients with comorbid autoimmune conditions. Here, we present a case of chronic spontaneous urticaria in a 9-year-old with type 1 diabetes and autoimmune thyroid disease who first presented with insulin pump site reactions concerning an insulin-related allergy. The patient was successfully treated with antihistamines and later immunosuppression with resumption of insulin pump therapy and remission of chronic spontaneous urticaria symptoms 18 months after onset.

A plague passing over: Clinical features of the 2022 mpox outbreak in patients of color living with HIV.

INTRODUCTION: Compared with previous geographically localized outbreaks of monkeypox (MPOX), the scale of the 2022 global mpox outbreak has been unprecedented, yet the clinical features of this outbreak remain incompletely characterized. METHODS: We identified patients diagnosed with mpox by polymerase chain reaction (PCR; n = 36) from July to September 2022 at a single, tertiary care institution in the USA. Demographics, clinical presentation, infection course, and histopathologic features were reviewed. RESULTS AND CONCLUSION: Men who have sex with men (89%) and people living with HIV (97%) were disproportionately affected. While fever and chills (56%) were common, some patients (23%) denied any prodromal symptoms. Skin lesions showed a wide range of morphologies, including papules and pustules, and lesions showed localized, not generalized, spread. Erythema was also less appreciable in skin of colour patients (74%). Atypical clinical features and intercurrent skin diseases masked the clinical recognition of several cases, which were ultimately diagnosed by PCR. Biopsies showed viral cytopathic changes consistent with Orthopoxvirus infections. All patients in this case series recovered without complications, although six patients (17%) with severe symptoms were treated with tecovirimat without complication.

Endoscopic Versus Microscopic Pediatric Tympanoplasty: Is There a Difference Between Closure Rates and Hearing Outcomes?

OBJECTIVE: To compare closure rates and hearing outcomes of microscopic and endoscopic tympanoplasty in pediatric patients. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary university medical center. PATIENTS: Pediatric patients who underwent tympanoplasty surgery by a fellowship-trained neurotologist between 2010 and 2019 with a minimum of 2 months of follow-up, a tympanic membrane perforation, and no preoperative cholesteatoma. INTERVENTIONS: Transcanal endoscopic tympanoplasty or microscopic tympanoplasty (MT) surgery. MAIN OUTCOME MEASURES: The primary outcome is postoperative closure of the tympanic membrane perforation, assessed using otomicroscopy at the last follow-up appointment. Secondary outcomes include operative time and changes in the air-bone gap (ABG) and pure-tone average (PTA). RESULTS: Two hundred eleven tympanoplasty operations were analyzed: 121 in the transcanal endoscopic ear surgery (TEES) group and 90 in the MT group. Tympanic membrane closure rates were no different between the two groups (TEES, 82.6%; MT, 88.9%; p = 0.24), and no significant association was found on multivariable analysis (TEES: odds ratio, 0.8; p = 0.61). Both groups showed improvements in the 4-month PTA and ABG and the 12-month PTA, but the 12-month ABG only improved in the TEES group ( p < 0.01). The TEES group had a shorter average operative time (109.8 versus 123.5 min; p = 0.03) and less need for a postauricular incision (2.5% versus 93.3%; p < 0.01). CONCLUSION: In pediatric tympanoplasty, TEES gives similar membrane closure and hearing outcomes as the microscopic technique, with less operative time and less need for a postauricular incision.

Patient Factors Predicting Success in Lateral Graft Tympanoplasty.

Objective: To compare the effects of preoperative medical comorbidities and operative findings on the success of lateral graft tympanoplasty. Study Design: Retrospective chart review. Setting: Tertiary medical center. Patients: Ninety-six patients undergoing lateral graft tympanoplasty from December 2008 to November 2020 with at least 2 months follow-up were included. Patient demographics, comorbidities including smoking status, intraoperative findings, and healing, and hearing outcomes were recorded. Interventions: Lateral graft tympanoplasty. Main Outcome Measures: The primary outcome was perforation closure. Secondary outcomes were postoperative complications and change in air-bone gap (ABG). Results: Ninety-nine ears (mean age 40.94 ± 18.44 years) were included. Tympanic membrane perforation closure was achieved in 92 (92.9%) ears. Perforation closure was not associated with diabetes (P > 0.99), smoking (P > 0.99), or the presence of cholesteatoma at the time of lateral graft tympanoplasty (P = 0.10). Increased age (odds ratio [OR] = 1.04, P = 0.31) was also not correlated with tympanic membrane closure rate. An absent malleus resulted in a higher rate of lateralization (31.3% versus 2.1%; OR = 18.41, 95% confidence interval [CI] = 3.09-95.95, P = 0.001) but not blunting (12.5% versus 4.8%; OR = 0.24, 95% CI = 0.49-12.93, P = 0.24). The mean ABG improved 6.82 ± 11.33 dB (P < 0.01). History of prior tympanoplasty was associated with smaller ABG improvement following surgery (ß = 4.038, R2 = 0.262, P = 0.04) but not perforation closure (OR = 3.25, 95% CI = 0.63-16.81, P = 0.24). Conclusions: Diabetes, active smoking, and advancing age were not associated with adverse healing in patients undergoing lateral graft tympanoplasty. Lateralization was more common with an absent malleus.
