The role of stress and mood in the onset and course of sickle cell disease (SCD) pain was examined using a daily diary design. Fifteen adults with SCD completed daily diaries about their pain, stress, mood, and health care and medication use for an average of 94 days. Multilevel random effects models indicated that stress was significantly and positively related to same-day pain ratings. ⋯ Mood also showed significant associations with same-day pain in the expected directions. In addition, stress and mood were associated with health care and medication use during painful episodes. Finally, painful episodes were preceded by increases in stress 2 days previously, suggesting that stress may play a role in the onset of SCD pain.

Intraventricular hemorrhage (IVH) in adults usually occurs in the setting of aneurysmal subarachnoid hemorrhage or hypertension-related intracerebral hemorrhage. Thus, the underlying cause of IVH is apparent from history and radiographic findings. If the underlying cause of IVH is not apparent, additional studies, including cerebral angiography, magnetic resonance imaging, and toxicology screening, should be performed to identify etiologic agents that may alter management of IVH. ⋯ Intraventricular injections of thrombolytic agents through an IVC is a treatment option that may be considered in all patients with IVH that is causing or threatening to cause obstructive hydrocephalus. Unrepaired cerebral aneurysms, untreated cerebral arteriovenous malformations, and clotting disorders are contraindications for this intervention. The surgical evacuation of IVH has a role only in very rare cases in which the IVH is causing a significant mass effect independent of hydrocephalus and associated intraparenchymal brain hemorrhage.

Clostridium perfiringens may cause myonecrosis (i.e. gas gangrene), acute food poisoning or necrotic enteritis (e.g. enteritis necroticans or Pig Bel). We describe a case of enteritis necroticans in a 33 year old man with acute myeloid leukaemia. ⋯ Treatment of enteritis necroticans requires urgent surgery to remove dead bowel and in adults intravenous penicillin (1g 2-hourly) and metronidazole (500 mg 8-hourly) or clindamycin (600 mg 6-hourly). While antibiotics may also reduce toxin formation, beta toxoid has not been found to be of benefit in established disease.

To discuss the clinical indications and complications of non-invasive ventilation. ⋯ Non-invasive ventilation using the modes of CPAP, PSV, BiPAP and NIPPV should be considered in patients with respiratory disorders who remain in acute respiratory failure despite conventional therapy, before considering invasive mechanical ventilation.

To detail the history, modes, physiological effects, and circuit geometry of non-invasive ventilation. ⋯ Non-invasive ventilation using the modes of CPAP, PSV, BiPAP and NIPPV should be considered in patients with respiratory failure who are unresponsive to conventional therapy, before considering invasive mechanical ventilation.
