Longitudinally Extensive Transverse Myelitis: A Sub-Saharan Conundrum, Antonina Obayo, Sylvia Mbugua, Sayed Karar

Internal Medicine, East Africa

Spinal cord schistosomiasis is a rare, underdiagnosed manifestation of schistosomiasis. We present the case of a 36-year-old male who presented to our institution with a one-week history of low back pain with rapidly progressive lower limb weakness, loss of sensation, and flaccid paraparesis. An MRI of the spine showed a longitudinally extensive transverse myelitis from T6 to L1, with enhancement at the cauda equina region. Further review of the images and serological tests eventually led to diagnosis of spinal schistosomiasis. He was treated with praziquantel and high-dose steroids, with minimal improvement in his symptoms.

Cardiospecific Overexpression Of Atpgd1 (Carnosine Synthase) Increases Histidine Dipeptide Levels And Prevents Myocardial Ischemia Reperfusion Injury, Jingjing Zhao, Daniel J. Conklin, Yiru Guo, Xiang Zhang, Detlef Obal, Luping Guo, Ganapathy Jagatheesan, Kartik Katragadda, Liqing He, Jasmit Shah

Internal Medicine, East Africa

Background: Myocardial ischemia reperfusion (I/R) injury is associated with complex pathophysiological changes characterized by pH imbalance, the accumulation of lipid peroxidation products acrolein and 4-hydroxy trans-2-nonenal, and the depletion of ATP levels. Cardioprotective interventions, designed to address individual mediators of I/R injury, have shown limited efficacy. The recently identified enzyme ATPGD1 (Carnosine Synthase), which synthesizes histidyl dipeptides such as carnosine, has the potential to counteract multiple effectors of I/R injury by buffering intracellular pH and quenching lipid peroxidation products and may protect against I/R injury.

Methods and Results: We report here that β-alanine and carnosine feeding enhanced myocardial …

Endobronchial Tuberculosis: A Rare Presentation, Nadeem Kassam, Omar M. Aziz, Samina Somji, Grace Shayo

Internal Medicine, East Africa

Endobronchial tuberculosis (EBTB) is an infection of the tracheobronchial tree by Mycobacterium tuberculosis. It is common among young females. Patient can present with fever, cough, wheeze, with or without any constitutional symptoms. It presents as a diagnostic dilemma, as patient sputum smear can be false negative. CT scan may or may not show any abnormality, or any endobronchial lesion. Bronchoscopy with bronchoalveolar lavage and biopsy offers the diagnostic choice. We hereby report a case of a young immunocompetent Asian female who was found to have endobronchial pathology, leading to diagnosis and timely therapy.
