Meta Analysis
Diagnosing Achilles Tendon Rupture with Ultrasound in Patients Treated Surgically: A Systematic Review and Meta-Analysis.
Achilles tendon rupture is a common injury with increasing incidence due to the rising popularity of high-velocity sports, continued physical activity of the aging American population, and use of fluoroquinolones and steroid injections. The diagnosis can often be missed or delayed, with up to 20% misdiagnosed, most commonly as an ankle sprain. ⋯ The results from our study suggested that a negative ultrasound result may have the potential to rule out a complete, as well as a partial, Achilles tendon rupture.

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.

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.

Burns are a common condition presenting to the emergency department; the majority are thermal burns. The treatment for thermal burns and chemical burns differs greatly, and prompt recognition of a chemical burn is necessary. An often unrecognized and underestimated type of chemical burn is an alkali burn from wet cement. ⋯ A 7-year-old boy was transferred from an outside facility for evaluation of burns after exposure to wet cement. The patient underwent partial decontamination at the outside facility with polyethylene glycol and, to prevent ongoing alkali burns, the patient necessitated further decontamination with irrigation. Burn surgery was consulted for additional evaluation. The patient required no further intervention and the patient was discharged to home and made a full recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Serious morbidity and mortality can occur from unrecognized cement burns, and early decontamination and evaluation by a burn surgeon is necessary. It is critical that emergency physicians both recognize and appropriately treat this condition in a timely manner to prevent adverse outcomes.
