Determination of left ventricular mass by echocardiography in a normal population: effect of age and sex in addition to body size.
In this study, we determined the effect of age, sex, and body size on left ventricular mass. ⋯ The findings in this study suggest that left ventricular mass, as assessed by two-dimensional-guided M-mode echocardiography, is affected not only by sex and body size but also by age in women. This phenomenon may be related to an increase in body mass index with advancing age in women. In clinical studies that use echocardiographic left ventricular mass to diagnose left ventricular hypertrophy, these observations should be considered.

During the past several decades, the transport of critically ill patients to and between hospitals has gradually improved. The major indications that necessitate emergency transport for adult patients are trauma and acute cardiac disease, and the establishment of transport teams trained in the care of these conditions has improved the outcome of adult patients. ⋯ Such a program emphasizes stabilization of the child's condition at the local hospital, followed by transport to a pediatric intensive-care facility by a specially trained pediatric transport team. In this review, we present an overview of the principles and operating procedures of such pediatric transport teams.

Ocular adnexal lymphoproliferative lesions consist of a spectrum of disease entities, including reactive lymphoid hyperplasia, atypical lymphoid hyperplasia, and lymphoma. No clinical or radiologic criteria facilitate a distinction among these lymphoproliferative lesions. The two hyperplastic processes may evolve to localized or systemic lymphoma. ⋯ In comparison, intermediate- and high-grade lymphomas are less common in the ocular adnexa but more aggressive. An approach to the diagnosis and treatment of these complex entities is suggested. Despite new pathologic classification schemes, immunophenotypic labeling, and molecular genetic analysis, the prognosis for patients with small-cell lymphoma in the ocular adnexa is difficult to predict.

The interruption of daily consumption of caffeine-containing beverages can cause headache and other symptoms within 8 hours. Resumption of caffeine alleviates these symptoms. Surgical patients routinely fast preoperatively and may have postoperative symptoms from caffeine withdrawal. ⋯ Perioperative intake of caffeine altered postoperative well-being. Caffeine given preoperatively may limit postoperative withdrawal headaches among the millions of daily drinkers of caffeinated beverages. A randomized, prospective, and blinded trial to test this hypothesis is warranted.
