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.

Cytomegalovirus as a trigger for systemic lupus erythematosus.

Cytomegalovirus (CMV) infections have been associated with exacerbations of systemic lupus erythematosus (SLE). Their role in triggering this disease, however, remains a subject of debate. We present a 43-year-old man with no history of systemic illness who developed persistent signs and symptoms of a CMV-associated mononucleosis-like syndrome while fulfilling diagnostic criteria for previously undiagnosed SLE.

Holoprosencephaly with proboscis.

This is the case of a male newborn with holoprosencephaly, marked hypotelorism, and a rudimentary nasal structure, the proboscis. The head CT scan showed a single monoventricle and two ocular globes fused at the midline. Chromosome studies showed a normal karyotype.
