A case of cardiac septal abscess in a patient with a porcine bioprosthetic aortic valve who gradually developed a complete atrioventricular block on successive electrocardiograms (ECG) is reported. Emergency physicians should consider endocarditis with septal abscess in a patient with a prosthetic heart valve who presents with fever and a new conduction defect on ECG.

Clinical literature suggests that those close to a trauma survivor may experience intrapersonal and interpersonal distress because of indirect or secondary effects of the trauma. The focus of this study is on the association between reported childhood physical and sexual abuse and current individual stress symptoms, relationship satisfaction, and family adjustment. The participants included 96 clinic couples who reported a history of childhood physical or sexual abuse in one or both partners and 65 clinic couples in which neither partner reported such abuse. Couples in which one or both partners reported childhood abuse reported significantly lower marital satisfaction, higher individual stress symptoms, and lower family cohesion than couples with no abuse history. No significant differences were found between individuals who reported a history of abuse and their partners who reported no history of childhood abuse, suggesting support for secondary trauma theory. Clinical and future research implications are discussed.
Betel nut is a common masticatory drug used in Far East Asia, India, and the South Pacific. It is used daily by 600 million people worldwide, yet is unknown to most Western physicians. As the world becomes more culturally and ethnically interconnected, emergency physicians will encounter the use of betel nut. Significant illness can be associated with its use, including asthma exacerbation, cholinergic crisis, cardiac arrhythmias, acute psychosis, milk-alkali syndrome, and oropharyngeal tumors. We describe its source, pharmacology, composition, presentation, and treatment in the emergency department.
Traumatically injured Jehovah's Witnesses pose difficult management problems because of their refusal to accept blood transfusions. This retrospective review of all inpatient traumatically injured Jehovah's Witnesses at a level I trauma center over the past 16 years revealed 77 patients with 92% blunt and 8% penetrating injuries. The primary physician was aware of their unique religious status in only 32% of cases. Transfusion was performed in only 4 (5.2%) cases even though it was desired by the physician in 11 (14%) cases. One transfusion was performed against the patient's will. One minor was transfused using a court order. Two transfusions were performed in the trauma room before the patients' religious status was known. Major changes in therapeutic plans were made as a result of the patients' Jehovah's Witness status in 10 cases (13%). Early knowledge of the patient's religious status is essential to optimize patient care.
