Our data suggest that obesity affects P-wave dispersion and duration, and changes in P dispersion may be closely related to the clinical and the echocardiographic parameters such as BMI, LAD, IVST, LVPWT, and LVM.

Bismuth subcitrate is a known nephrotoxic agent that may lead to acute oliguric renal failure when ingested in toxic doses. We report a 17-year-old girl who was admitted to the emergency room with complaints of nausea, vomiting, and anuria. She had taken 25 tablets containing 300 mg bismuth subcitrate (total 7.5 g). The patient was managed with hemodialysis started a week after ingestion. Bismuth subcitrate nephrotoxicity should be considered in the differential diagnosis of acute renal failure.
