RESUMEN
With an estimated contribution of up to 6% of all acute coronary events, young adults are experiencing an escalating burden and mortality attributable to coronary artery disease (CAD) worldwide. Wellens syndrome, a preinfarction clinical entity with distinctive electrocardiographic (ECG) features and high propensity for extensive anterior wall infarctions, affects about 15% of unstable angina subpopulation. We report challenges and lessons learnt from the first ever documented case of Wellens syndrome in Tanzania. A 30-year-old female of African descent was referred to us from an upcountry zonal referral hospital for etiological determination of chest pain and expert management. Her medical history was unremarkable, and she had no apparent risk factors for CAD. She presented with a 7-day history of ongoing sharp central chest pain that was radiating to the neck and jaws and relieved momentarily by morphine. She had stable vitals with an unremarkable systemic examination; however, a 12-lead ECG revealed deeply inverted T-waves on leads V2 through V4. Based on our extensive history and physical examination we came up with a diagnosis of type B Wellens syndrome with impending anterior wall myocardial infarction. She underwent cardiac catheterization that revealed a nonthrombogenic severe subocclusive (>95%) mid left anterior descending artery stenosis. Subsequently, angioplasty was performed successfully with a resolute integrity stent, and TIMI III flow was achieved. To conclude, despite its relative frequency, physicians' awareness of Wellens syndrome pathognomonic ECG features is of paramount importance to curb its attributable morbidity and mortality.

Globally, schistosomal infections affect over 200 million people resulting in the loss of 70 million disability-adjusted life years. In the sub-Saharan Africa region, where over 85% of the global schistosomal infections are found, it is estimated that about 120 million people become symptomatic, over 20 million have severe disease, and nearly 200 000 die every year. Renal impairment is a severe consequence of schistosomiasis occurring in about 6% of all infected individuals and in 15% of those with the hepatosplenic form. We present a case of massive bilateral hydroureteronephrosis and end-stage renal disease resulting from chronic schistosomiasis in a 38-year-old male of African origin. A 38-year-old male rice farmer of African origin presented with a history of elevated blood pressure, abdominal swelling, and reduced urinary output for about 10 months. Abdominal examination revealed an intraabdominal mass measuring 30 cm × 17 cm extending from the right hypochrondrium region downward to right inguinal outward to umbilicus crossing the midline. He had an estimated glomerular filtration rate of 3.9 mL/min, hemoglobin of 6.78 g/dL, and had multiple electrolyte abnormalities. A computed tomography intravenous urogram scan of the abdomen revealed hepatomegaly (18 cm), bilateral renal enlargement with hydroureteronephrosis, and multiple calcifications on the urinary bladder. A rectal biopsy isolated haematobium eggs and confirmed the diagnosis. Urinary schistosomiasis can have distressing effects on the urinary system in particular and survival prospects in general. In view of this, extensive evaluation of the genitourinary system is pivotal for timely diagnosis and prompt management particularly in residents of schistosoma-endemic communities presenting with obstructive uropathy.
