Aerococcus urinae is a rare cause of urinary tract infection (UTI) seen in elderly males with multimorbidity. Incidence is estimated between 0.15 and 0.8%. This organism is frequently misidentified for other grampositive species. Missed or delayed diagnosis of A. urinae UTI can lead to systemic infection with high morbidity and potential mortality. We present a classic case of A. urinae UTI in a 91-year-old male with multiple comorbidities, including heart failure, diabetes mellitus, and metastatic prostate carcinoma. Empiric therapy with nitrofurantoin was unsuccessful, but intravenous ceftriaxone and bladder catheterization resulted in rapid symptomatic improvement. Variable antimicrobial sensitivities and resistance have been reported for A. urinae. Therefore, antimicrobial resistance testing should be performed for all patients with A. urinae infections.
Statin therapy is a widely prescribed medication class for hypercholesterolemia. In statin-induced autoimmune myopathy, genetically predisposed and at-risk patients can develop antibodies against hydroxy-3-methylglutaryl-CoA reductase (HMGCR), the key enzyme in the production of cholesterol. As a result, an autoimmune reaction causing weakness, myalgia, with possible severe rhabdomyolysis, renal failure, and myonecrosis also can occur. A 73-year-old female presented to clinic with myalgia and fatigue. She was on atorvastatin 20 mg/day for over 1 year, which she stopped 1 week prior to her initial presentation. Patient did experience rhabdomyolysis as well as a transaminitis. She underwent an autoimmune workup which was positive for HMG-CoA reductase antibodies. Patient was initially treated on a prednisone taper, starting dose 50 mg/day. Without remission of symptoms, methotrexate 15 mg/week was initiated.
Paget-Schroetter syndrome (PSS) is a rare form of spontaneous upper extremity deep vein thrombosis associated with vigorous activity of the upper extremities. We present a rare case of a young swimmer who presented with a painful right upper extremity swelling, with compression ultrasound (CUS) revealing extensive venous clots in the basilic, axillary, and subclavian veins. Venous duplex revealed extrinsic compression of the subclavian vein, and catheter-based contrast venography confirmed our diagnosis of PSS. The patient was started on a therapeutic dose of subcutaneous enoxaparin and referred to a higher center for further intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
