Unexpected fatal hypernatremia after successful cardiopulmonary resuscitation with therapeutic hypothermia: a case report.

Central diabetes insipidus (DI), characterized by unexpected fatal hypernatremia, is a rare complication after successful cardiopulmonary resuscitation with therapeutic hypothermia, but may be potentially fatal if recognition is delayed. We describe here a patient who experienced cardiac arrest due to a pulmonary embolism, followed by successful resuscitation after induction of therapeutic hypothermia. The patient, however, suddenly developed unexpected hypernatremia with increased urine output and was diagnosed with central DI as a complication of cerebral edema, and eventually died.

Clinical characteristics of pneumonia in hospitalized patients with novel influenza A (H1N1) in Korea.

In March 2009, a novel influenza H1N1 virus (2009 H1N1) emerged and spread worldwide. We describe the clinical course of pneumonia in patients hospitalized with 2009 H1N1 in Korea from August to mid-October 2009. Of 351 patients with a confirmed 2009 H1N1 infection, a total of 17 patients with pneumonia were admitted to an acute care unit.
