RESUMEN
Multisystem inflammatory syndrome in children (MIS-C) is a potentially severe inflammatory syndrome following recent infection with SARS-CoV-2 (COVID-19). In this report, we describe a 13-year-old boy with a retropharyngeal abscess unresponsive to initial antibiotic therapy who was found to have findings consistent with MIS-C, which included elevated interleukin-6, ferritin, and troponin levels. The patient had COVID-19 infection due to the Omicron variant.
RESUMEN
Episodic (recurrent) macroscopic hematuria in patients with IgA nephropathy is usually associated with a benign prognosis, although some patients experience a transient fall in glomerular filtration rate during the episodes. We present a 15-year-old girl with mild IgA nephropathy who had multiple episodes of macroscopic hematuria associated with severe but transient decreases in estimated glomerular filtration rate, low levels of serum uric acid, and marked increases in fractional excretion of uric acid. Ultrasound studies showed marked inflammatory changes in the bladder, especially involving the trigone. Cystoscopic findings were consistent with these changes. We hypothesize that the macroscopic hematuria may have resulted, at least in part, from hyperuricosuria causing acute irritation of the bladder mucosa in the trigone area.
RESUMEN
We present a case of a 74-year-old woman, who was on nitrofurantoin treatment for urinary tract infection (UTI), with fever and chills 7 hours after taking nitrofurantoin. She was hospitalised and evaluated for worsening UTI and sepsis. Initially, it appeared to be secondary to post-UTI sepsis because of possible resistant infection or conditions like pulmonary embolism or acute hepatitis. The patient also developed systemic inflammatory response syndrome, left bundle branch block (LBBB), thrombocytopaenia and transaminitis. Considering the side effects of nitrofurantoin, it was stopped. The patient showed improvement and recovered completely with symptomatic and supportive treatment. During follow-up visits with her primary care physician, thrombocytopaenia, transaminitisandLBBB were found to have been resolved.
