Hypoxic events and cardiac arrest may cause brain damage in critical infants. This study investigated cerebral tissue oxygenation and oxygen extraction in a piglet model of hypoxic events, cardiac arrest and effects of resuscitation. ⋯ Noninvasive monitoring of rScO2 and evaluating FTOE changes during hypoxia and resuscitation may help clinicians evaluate brain tissue oxygenation and viability.

Mixed germ cell tumors with non-germ cell malignant components rarely occur in the anterior mediastinum. We report a case of a 34-year-old man who presented with an anterior mediastinum mass. ⋯ Pathologic examination of the excised specimen showed predominantly malignant ganglioneuroma and small residual foci of teratoma. To our knowledge, this is the first reported case of a malignant ganglioneuroma arising from mediastinal mixed germ cell tumor.

Whether decompressive hemicraniectomy is an appropriate treatment for malignant middle cerebral artery (MCA) infarction is still a controversial issue. The aims of our study were to determine survival rate and functional out-come and to determine factors associated with survival rates and functional outcome in patients with malignant MCA infarction. ⋯ Decompressive hemicraniectomy may be a useful procedure in patients with malignant MCA infarction. Age, clinical signs of herniation and timing of surgery were the prognostic factors associated with mortality and functional outcome.
