Ibuprofen Overuse Leading to Life-threatening Hypokalemia Associated with Renal Tubular Acidosis in Two Patients.

Ibuprofen is a commonly used medication in the United States and is used both by prescription and over the counter, while hypokalemia is a life-threatening condition caused by various etiologies, one of which is the side effect of medications. Ibuprofen is well-known for its various nephrotoxic side effects, including hyperkalemia as a common electrolyte abnormality, however, renal tubular acidosis leading to hypokalemia with the use of ibuprofen has been reported rarely. We present here two cases of life-threatening hypokalemia due to over-the-counter use of large doses of ibuprofen and describe its management.

Celiac Artery Portal Vein Fistula After Transjugular Intrahepatic Portosystemic Shunt Presenting as Heart Failure.

Transjugular intrahepatic portosystemic shunt (TIPS) is an important therapeutic tool available to decrease portal vein pressure in patients with cirrhosis and portal hypertension. TIPS is associated with various complications, and fistula formation is an important one to be noted. We present an unusual and interesting case of a patient who developed right-sided heart failure 5 months after TIPS placement.

Pseudodiverticulosis: a rare presentation of eosinophilic esophagitis.

Esophageal pseudodiverticulosis is a rare endoscopic finding in eosinophilic esophagitis. We report a case of a 32-year-old male who presented with dysphagia and gastroesophageal reflux disease and was found to have esophageal pseudodiveritcula along with esophageal rings. The patient was subsequently treated with endoscopic balloon dilation and a diagnosis of eosinophilic esophagitis (EoE) with pseudodiverticulosis was made based upon the endoscopic and biopsy findings.
