The long QT syndrome is characterized by the observed association of "torsade de pointes" and the prolongation of the QT interval on the electrocardiogram. Acquired long QT syndrome typically affects older individuals, being often associated with the action of some drugs. Hypokalemia is a frequent cause of QT lengthening on the electrocardiogram. Chronic assumption of licorice may be an unusual...

Thyrotoxic hypokalemic periodic paralysis (THPP) is an endocrine emergency marked by recurrent attacks of muscle weakness associated with hypokalemia and thyrotoxicosis. Asiatic male patients are most often affected. On the other hand, African descents rarely present this disease. The case described shows an afrodescendant patient with hypokalemia and tetraparesis, whose diagnosis of hyperthyro...

Ibuprofen is widely used in the community to manage pain, inflammation and fever. In cases of prolonged and supratherapeutic ingestion of ibuprofen, renal tubular acidosis (RTA) with profound hypokalemia may occur. Although hypokalemia is known to cause rhabdomyolysis, rhabdomyolysis occurring in the setting of ibuprofen-induced RTA is rare. We present an unusual case of a 34-year-old male who ...

Renal ammonia metabolism is the predominant component of net acid excretion and new bicarbonate generation. Renal ammonia metabolism is regulated by acid-base balance. Both acute and chronic acid loads enhance ammonia production in the proximal tubule and secretion into the urine. In contrast, alkalosis reduces ammoniagenesis. Hypokalemia is a common electrolyte disorder that significantly incr...

A 26 -yearold woman presented with rhabdomyolysis secondary to severe hypokalemia. Hypertension and metabolic alkalosis could lead to the suspicion of primary aldosteronism, which was confirmed by a decreased plasma rennin, elevated plasma aldosterone levels and high aldosterone/rennin ratio additionally. Additionally adrenal computed tomography showed an adrenal tumour. Blood pressure and hypo...

Tenofovir is a nucleotide analog reverse transcriptase inhibitor approved for the treatment of HIV and hepatitis B infections. It is widely prescribed and an integral part of the recommended regimens for the treatment of HIV infection in antiretroviral-naive patients. Tenofovir is implicated in renal proximal tubular dysfunction, which can be associated with Fanconi syndrome and hypokalemia. Wh...

Severe hypokalemia can have life-threatening complications such as significant muscle weakness, ileus, rhabdomyolysis, and respiratory failure. Here, we report a case of 33-year-old male who presented with worsening lower extremity weakness falls after smoking marijuana for six months. Initial labs showed severe hypokalemia. EKG was remarkable first-degree AV block, widened QRS complex, ST segm...

BACKGROUND Pituitary adenoma is one of the most common intracranial neoplasms, and its primary treatment is endoscopic endonasal transsphenoidal tumorectomy. Postoperative hypokalemia in these patients is a common complication, and is associated with morbidity and mortality. This study aimed to analyze the etiopathology of postoperative hypokalemia in pituitary adenomas after endoscopic transsp...
