To evaluate the individual components of a cardiac multimarker panel in the detection of acute myocardial infarction (AMI) in patients with chest pain across a spectrum of renal dysfunction. ⋯ A point-of-care, rapid cardiac biomarker strategy utilizing cTnI is applicable and superior to MYO or CK-MB in the evaluation of chest pain in patients with renal dysfunction.

Patients with diabetic ketoacidosis (DKA) hyperventilate, lowering their alveolar (PACO(2)) and arterial carbon dioxide (PaCO(2)). This ventilatory response lessens the severity of their acidemia in a predictable way. Because end-tidal CO(2) (ETCO(2)) closely approximates PaCO(2), measured ETCO(2) levels should allow for predictions about the presence and severity of acidosis in diabetic patients. ⋯ End-tidal CO(2) is linearly related to HCO(3) and is significantly lower in children with DKA. If confirmed by larger trials, cut-points of 29 torr and 36 torr, in conjunction with clinical assessment, may help discriminate between patients with and without DKA, respectively.

In 1991, the American Boards of Internal Medicine and Emergency Medicine changed their credentialing requirements to recognize training common to both disciplines. This allowed the formation of a five-year track for dual board eligibility. From 1995 to 1998, 28 physicians graduated from eight emergency medicine/internal medicine (EM/IM) programs. This study was an analysis of career outcomes of these graduates. ⋯ Although the majority of EM/IM graduates do not practice both IM and EM, many would prefer to. The graduates are highly satisfied with their choice of residency and career. Early in career development, the graduates appear to gravitate toward academic and leadership positions.
