Clostridial myonecrosis (CM) is a rare, life-threatening infection that is most often associated with recent surgery or skeletal muscle trauma. It usually affects patients with some degree of underlying immunocompromise or vascular insufficiency. Occasionally, CM can occur at remote sites, with seeding from a gastrointestinal source in the setting of malignancy. ⋯ On autopsy, this patient was found to have previously undiagnosed radiation colitis with ulcerations and abscess formation, secondary to recent prostate cancer radiation therapy. Although several case reports discuss CM in the setting of bowel malignancy, our case illustrates that non-malignant bowel inflammation may be a sufficient source for the infection. Clinical features of this uncommon disease are discussed, and the relevant literature is reviewed with regard to Clostridium septicum as an etiologic agent.

Our objectives were to evaluate the frequency of beta-blocker administration in the setting of acute myocardial infarction (AMI) where angioplasty is the primary treatment, and to investigate emergency physician's (EPs) attitudes toward beta-blockers. We performed a retrospective chart review of all patients who presented with symptoms and electrocardiogram (EKG) criteria consistent with AMI in the defined study period. Charts were reviewed for beta-blocker administration and other treatments. ⋯ Bradycardia was the most frequent reason for withholding beta-blockers. In this series of patients presenting with AMI, beta-blockers were greatly underutilized. The self-reported reasons of EPs for withholding beta-blocker therapy did not explain why 72% (49/68) of patients without contraindications did not receive beta-blockers.

Baclofen (Lioresal) is a drug of choice to treat spasticity and is increasingly being administered intrathecally via an implantable pump in cases refractory to oral therapy. Emergency physicians will likely treat patients with baclofen withdrawal or overdose as this treatment becomes more widespread. ⋯ Baclofen withdrawal may mimic other diseases including sepsis, meningitis, autonomic dysreflexia, malignant hyperthermia, or neuroleptic malignant syndrome. Treatment consists of supportive care, reinstitution of baclofen, benzodiazepines, and diagnosis and eventual repair of intrathecal pump and catheter malfunction.

Thrombotic thrombocytopenic purpura (TTP) is a rare clinical entity. It is a multi-systemic disorder characterized by a clinical pentad of thrombocytopenia, microangiopathic hemolytic anemia, diffuse and nonfocal neurologic symptoms, decreased renal function, and fever. ⋯ The clinical diagnosis of TTP is generally difficult because there are many varied clinical presentations and the full expression of the pentad may be prolonged. However, once the diagnosis is suspected or confirmed, immediate plasmapherseis with plasma exchange must be performed to reduce the severe morbidity from neurologic disability.
