A Rare Manifestation Of Mycobacterium Kansasii As A Cutaneous Infection: A Case Report, Wandera Carey, Antony Kimani, Zamanali Khakhar, Dheer Kalaiya, Alok Iyer, Sayed Karar

Internal Medicine, East Africa

Nontuberculous mycobacteria (NTM) are environmental organisms increasingly recognized as opportunistic pathogens, particularly in immunocompromised individuals. Mycobacterium kansasii, a slow-growing photochromogen (Runyon group I), is primarily associated with pulmonary disease; however, extrapulmonary and cutaneous manifestations are uncommon and often underdiagnosed. Given the rising incidence of NTM infections, cutaneous disease should be considered in the differential diagnosis of skin lesions, especially in immunocompromised patients. Early microbiological confirmation is crucial for appropriate therapy, as M. kansasii is intrinsically resistant to pyrazinamide. Herein, we present a case of pathologically confirmed cutaneous M. kansasii infection occurring in isolation, illustrating the diagnostic challenges and therapeutic outcomes.

Navigating Complex Esophageal Perforations: A Case-Specific Approach To Successful Outcomes, Harsimran Kalsi, Anushree Rai, Kobina Essilfie-Quaye, Neeka Akhavan, Yaseen Perbtani, Tony S. Brar

HCA Healthcare Journal of Medicine

Esophageal perforation is a life-threatening condition requiring prompt diagnosis and effective management. While self-expanding metal stents (SEMS) are a first-line treatment, persistent leaks often necessitate adjunctive endoscopic interventions. A structured, multimodal approach is critical for optimizing outcomes and avoiding surgical intervention. A 44-year-old man developed an iatrogenic esophageal perforation following surgical leiomyoma enucleation. Initial treatment with overlapping fully covered self-expanding metal stents (FC-SEMS) failed to achieve closure, necessitating endoscopic suturing for defect reinforcement. Despite suturing, persistent leakage required placement of a larger-diameter FC-SEMS, secured with an endoscopic fixation system to prevent migration. Serial imaging confirmed successful defect closure, allowing the …

Atrial fibrillation (AF) is the most common arrhythmia and has been long recognized as a cause for atrial thrombus formation leading to cardioembolic stroke. However, recent studies reveal that the relationship between atrial fibrillation and stroke is an association rather than a temporal relationship. Left atrial thrombus formation is associated with vascular risk factor, atrial remodeling, and thrombogenesis. Various atrial electrical and structural markers of atrial myopathy have been linked to ischaemic stroke, even in the absence of AF. In addition to the CHA2DS2-VASc score as a consideration for anticoagulant administration, accurate atrial myopathy markers are needed to allow early …

Background. Safety supports psychological wellbeing and potentially shapes brain aging yet existing scales overlook cumulative lifespan safety experiences.

Methods. To address this gap, we developed and validated the Lifetime Sense of Safety (LSS) scale in Kenyan adults. The LSS uses visual analog scaling with a red-to-green color gradient to retrospectively rate felt safety across life stages and settings. We evaluated scale psychometrics and associations with social determinants of health and indicators of brain health.

Results. The LSS shows adequate internal consistency and test-retest reliability, with two distinct but correlated factors representing childhood and adulthood safety. Women and …

Internal Medicine, East Africa

Anti-melanoma differentiation-associated gene 5 (MDA-5) dermatomyositis is an uncommon condition that is frequently complicated by rapidly progressive interstitial lung disease (RP-ILD), resulting in a poor prognosis. Due to its aggressive course, management is often challenging and requires timely interventions to improve outcomes. This case of a female patient with anti-MDA-5-positive DM and RP-ILD aims to document this unique and uncommon condition, its aggressive clinical course, associated complications, diagnostic challenges, and management considerations.
