Intravenous recombinant tissue plasminogen activator (IV rt-PA) is the only established thrombolytic therapy for acute ischemic stroke. However, secondary embolism after IV rt-PA for acute ischemic stroke is recognized as an uncommon complication, and the pathophysiology is unclear. ⋯ Because the patient has paroxysmal atrial fibrillation (Af), the possible embolic sources may come from fragmentation of pre-existing intra-atrial clot. Although Af and the presence of cardiac thrombus are not contraindication for IV rt-PA in acute ischemic stroke, our case and review suggested that the administration of IV rt-PA to patients with known Af and intracardiac thrombus could represent a particular risk situation and should be carefully evaluated.

Wernicke encephalopathy (WE) is a medical emergency caused by thiamine (vitamin B1) deficiency. Typical clinical manifestations are mental change, ataxia, and ocular abnormalities. Wernicke encephalopathy is an important differential diagnosis in all patients with acute mental change. ⋯ Axial fluid-attenuated inversion recovery images showing symmetrical hyperintensity lesions in dentate nuclei of cerebellum, olivary bodies, and dorsal pons. Although atypical MRI findings are more common in nonalcoholic WE, it can also occur in alcoholic WE. This article is aimed to highlight the potential pitfalls in diagnosing acute mental change, the importance of clinical suspicion, and early treatment in WE.

Gastric rupture is a rare complication after cardiopulmonary resuscitation (CPR). In most cases, incorrect management of airways during CPR is the main cause. ⋯ He eventually presented with bloody vomitus and a tympanic abdomen. When faced with a patient with abdominal signs post-CPR, surgical complications of CPR should be considered.

Unilateral paralysis is rarely reported to be primary presentation of severe hypokalemia. We describe a 24-year-old woman who presented to the emergency department with sudden onset of right-sided weakness. Neurologic examination revealed diminished muscle strength and tendon reflexes over the right limbs. ⋯ However, laboratory data showed hypokalemia (K+ 2.0 mmol/L) with metabolic acidosis (HCO3 − 19 mmol/L). She needed a total of 260 mmol K+ to achieve complete recovery of muscle strength at a serum K+ level of 3.2 mmol/L and was proved to have distal renal tubular acidosis. Severe hypokalemia must be kept in mind as a cause of acute unilateral paralysis without organic lesions to avoid unnecessary examination and potentially life-threatening complications.

The aim of this study was to investigate the association between sex, cardiopulmonary resuscitation efforts, and outcomes of out-of-hospital cardiac arrests in Korea. ⋯ Females were less likely than males to receive resuscitation. Female sex was associated with a higher rate of survival at admission rate, whereas it was not associated with survival at discharge.
