Thyrotoxic hypokalemic periodic paralysis is a rare but potentially fatal emergency: case report and literature review.

We report a case of a 39 year-old Asian man in whom profound lower limb paralysis, along with severe hypokalemia and electrocardiographic changes, were the presenting features of Graves' disease (GD)-related thyrotoxicosis. Rapid recognition and management of the disorder were the key factors to avoid fatal hypokalemia-induced cardiac arrhythmias and promptly restore patient's capacity to ambulate.

Hopeful waiting: positive outcome of blood pressure monitoring in an emergency department.

Unlabelled: Hospitals use a triage system in which health care staff sort's patients into groups. During the long waiting periods after triage, inadvertence of patient's clinical deterioration may occur.

Objectives: To determine whether vital signs and oxygen saturation monitoring and reassessment of medical priority during the waiting period had a positive impact on the clinical outcome of apparently non-critical patients.

Acute hepatitis A infection: a predisposing factor for severe leptospirosis.

Leptospirosis is a rare and potentially fatal infection that requires a high index of suspicion for timely diagnosis and treatment. Diagnosis of leptospirosis can be particularly difficult in context of coexistent viral hepatitis. We present a case of Weil's syndrome, in which a concurrent resolving Hepatitis A virus infection was concomitantly diagnosed.

Development of Grave's disease seven months after Hashimoto's thyroiditis: a rare occurrence.

Hashimoto's thyroiditis (HT) and Graves' disease (GD) are two opposite poles in the spectrum of autoimmune thyroid disease. On one extreme, HT or Chronic Lymphocytic thyroiditis (CLT) courses, as its name implies, with lymphocytic infiltrates replacing thyroid follicles, resulting in a loss of hormone-producing cells and, thus, primary hypothyroidism. On the other extreme, GD is characterized by primary hyperthyroidism due to stimulating autoantibodies against thyroid-stimulating hormone receptors (TSHRs) localized on thyrocytes' membranes of intact thyroid follicles.
