The authors report a case of acute methemoglobinemia in a patient treated with naproxen for the common cold. A 42-year-old Asian woman began taking naproxen sodium and methocarbamol formylagia, chills, and coughing. On the day prior to her emergency department (ED) admission,the patient was taking lorazepam, trazodon, and paroxetine in addition to the naproxen and methocarbamol prescribed for the cold symptoms, and she also ingested approximately 300 mL of 20% alcohol. ⋯ After 10 days in the hospital, the patient was discharged without any complications. Naproxen is known to cause oxidative stress. Alcohol is known to reduce G6PD activity, and thus it is hypothesized that the administration of naproxen in an alcohol-dependent patient caused methemoglobinemia.

Benzodiazepines are widely used for many diseases, and benzodiazepine overdose is globally increasing in proportion to its prescriptions. Although most benzodiazepine overdoses are known to be safe and nonfatal without coingestions, morbidity or mortality after benzodiazepine overdose is closely related with the duration of unconsciousness or depth of compromised airway. Proper use of flumazenil, a potent antidote of benzodiazepine, seems to accelerate the recovery from the toxicity after benzodiazepine overdose. However, as the case we present demonstrates, careful attention and repetitive evaluations before and after use of flumazenil may be needed in benzodiazepine overdose because resedation occurs in approximately 30% of total flumazenil-treated cases, which suggests that the risk of aspiration or incidental death after administrating flumazenil might be significant without careful monitoring.

Pediatric cerebrospinal fluid shunt malfunctions can present with varying complaints. The primary cause is elevated intracranial pressure (ICP). ⋯ A rare presenting complaint is cardiac arrest. Immediate ICP reduction is the only reversible option for this type of cardiac arrest.

Case Reports
Life-threatening hemothorax due to azygos vein rupture after chest compression during cardiopulmonary resuscitation.
Hemothorax is not an uncommon cardiopulmonary resuscitation(CPR)–related complication. But hemothorax related to azygos vein injury (AVI) is a rare condition following blunt chest trauma, with no report of CPR-related AVI in the literature. ⋯ She eventually presented with massive hemothorax due to azygos vein rupture diagnosed by computed tomography (CT). When faced with a patient with massive hemothorax after chest compression, azygos vein rupture should be considered as a complication.
