Identification of portal venous gas on radiographic imaging is well documented after the ingestion of hydrogen peroxide, as is its resolution after hyperbaric therapy. Although hyperbaric therapy may resolve the gastrointestinal symptoms associated with the presence of portal venous gas, the principle rationale for performing hyperbaric therapy is to prevent subsequent central nervous system oxygen embolization. ⋯ We describe a patient with portal venous gas identified by computed tomography after the ingestion of 3% hydrogen peroxide, managed without hyperbaric therapy, who subsequently developed portal venous thrombosis. We are not aware of this complication being previously described from hydrogen peroxide ingestion. The case is complicated by the coexistence of a self-inflicted stab wound, leading to exploratory laparotomy in a patient predisposed to arterial vascular occlusion. Why Should an EmergencyPhysicianBeAware of This? Emergency physicians will encounter patients after the ingestion of hydrogen peroxide who, despite not having symptoms of central nervous system emboli, have portal venous gas identified on radiographic imaging. Being aware that the principle rationale for prophylactic utilization of hyperbaric therapy is to prevent subsequent central nervous system emboli, and that in at least one case, delayed-onset portal venous thrombosis has occurred without hyperbaric therapy may help contribute to clinical decision-making.

Osmotic demyelination syndrome commonly occurs after rapid correction of hyponatremia. But it has also been reported after graded correction of hyponatremia in the presence of other risk factors like chronic alcoholism, malnutrition, liver disease, and hypokalemia. ⋯ We report a case of a 67-year-old man who presented with dysphagia and nasal regurgitation and had features suggestive of bulbar palsy on neurological examination. He had spontaneous rapid correction of hyponatremia from a serum sodium level of 122 mEq/L to 132 mEq/L after discharge from our hospital. Neuroimaging was suggestive of extrapontine myelinolysis involving the basal ganglia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: An emergency physician should be aware of this because osmotic demyelination syndrome should also be considered in the differential diagnosis of patients presenting with bulbar palsy to the emergency department.

Emergency physicians express concern administering a 30-cc/kg fluid bolus to septic shock patients with pre-existing congestive heart failure (CHF), end-stage renal disease (ESRD), or obesity, due to the perceived risk of precipitating a fluid overload state. ⋯ Septic shock patients with pre-existing CHF, ESRD, or obesity are less likely to achieve compliance with a 30-cc/kg weight-based fluid goal compared with those without these pre-existing conditions.

Pneumorrhachis is an uncommon radiographic finding and is typically found in adult patients secondary to trauma or pneumocephalus. It is extremely rare in the pediatric population. Our case report describes a young boy who was found to have pneumorrhachis, but initially presented with an isolated back laceration. ⋯ An 8-year-old boy arrived to the emergency department as a transfer from an outside hospital after initially presenting with a back laceration. After laceration repair, he developed severe headache and vomiting when sitting upright from a supine position. He was found to have T3 fractures and pneumocephalus secondary to pneumorrhachis and was managed conservatively per neurosurgery recommendations. Why Should an Emergency Physician Be Aware of This?Although extremely rare in the pediatric population, pneumorrhachis must still be considered in any pediatric patient with a penetrating injury to the abdomen, respiratory tract, or spinal column. Cases without clear etiology require further evaluation for occult spinal injuries and fractures. Conservative management is typically sufficient, although certain situations require further intervention.

Boerhaave's syndrome is characterized by transmural rupture of the distal esophagus in the setting of increased intraluminal pressures combined with negative intrathoracic pressure. It is a rare condition with high mortality (20-50% mortality rate). ⋯ This is a case of a 47-year-old man who appeared acutely ill, presenting with shortness of breath, chest and abdominal pain, and diagnosed with Boerhaave's syndrome with the assistance of bedside ultrasound. WHY SHOULD AN EMERGENCY PHYSICIANS BE AWARE OF THIS?: Emergency physicians must have a heightened suspicion of this diagnosis in patients presenting with chest and abdominal pain and can use bedside ultrasound skills to aid with diagnosis.
