Human infection with Histoplasma capsulatum runs the gamut from asymptomatic to disseminated disease. CT-directed fine-needle aspiration of bilaterally enlarged adrenal glands has been used in diagnosing serious infections with this ubiquitous organism. Three cases have previously been reported in which H. capsulatum infection caused unilateral adrenal enlargement; this enlargement was diagnose...

Chronic increases in arterial blood flow elicit an adaptive response of the arterial wall, leading to vessel enlargement and reduction in wall shear stress to physiological baseline value. Release of nitric oxide from endothelial cells exposed to excessive shear is a fundamental step in the remodeling process, and potentially triggers a cascade of events, including growth factor induction and m...

Radiographic evidence of asymmetrical enlargement of the left atrium without atrial infarction is presented. Giant atrial enlargement is rarely symmetrical, the atrial appendage can contribute to the enlargement, and the giant atrium can be effectively trimmed. This will reduce its size and, therefore, the space which it occupies, and will restore the anatomical relations of neighbouring struct...

New criteria for the electrocardiographic recognition of right atrial enlargement, left atrial enlargement, and combined atrial enlargement were studied in 110 patients with congenital and acquired heart disease. Precise physiologic data weife available in all cases. The method of analysis was designed for application to conventional scalar electrocardiography and hence can be used without modi...

Right atrial (RA) size was determined with two-dimensional echocardiography using the apical four-chamber view in 45 adult patients with various echocardiographic criteria for RA enlargement and in 25 normal controls. RA size varied from 11.4-24.0 cm2 (mean 16.1 cm2) in controls. RA enlargement (greater than or equal to 25 cm2) was found in only two of 11 patients with P pulmonale (predictive v...

BACKGROUND Tunnel enlargement and coalition following double-bundle anterior cruciate ligament (ACL) reconstruction with hamstring tendon autografts has not yet been sufficiently studied. HYPOTHESIS The incidence and the degree of femoral tunnel enlargement will be significantly greater than those for tibial tunnel enlargement after anatomic double-bundle ACL reconstruction using hamstring te...

OBJECTIVE To quantitatively assess the degree and rate of splenic enlargement and the time required for regression of splenic enlargement in collegiate athletes diagnosed with acute infectious mononucleosis (IM). DESIGN Prospective cohort study. SETTING Academic Medical Center(s) outpatient sports medicine clinic. STUDY PARTICIPANTS Volunteer Division I University athletes. INTERVENTION...

The enlargement of plant cell walls is a key determinant of plant morphogenesis. Current models of the cell wall are reviewed with respect to their ability to account for the mechanism of cell wall enlargement. The concept of primary and secondary wall loosening agents is presented, and the possible roles of expansins, xyloglucan endotransglycosylase, endo-1,4-beta-D-glucanase, and wall synthes...

Serial computed tomographic scans in 39 closed head injury patients were measured by planimetry. The ventricle-brain ratio was computed, and the lateral ventricles were considered to be enlarged or normal based on measurements from a control group. Delayed ventricular enlargement was common after head injury producing low Glasgow Coma Scale scores and prolonged coma, whereas subarachnoid/intrav...

Gingival enlargement poses functional as well as cosmetic problems. It affects the quality of life by interfering with mastication, speech, occlusion and maintaining optimal oral hygiene .Gingival enlargement induced by cyclosporine A has been well documented in the literature. Only few studies, however, have associated the occurrence of such condition with the use of tacrolimus. A case of 48 y...
