Renal interlobar artery parameters with duplex Doppler sonography and correlations with age, plasma renin, and aldosterone levels in healthy children.

Objective: The objectives of this study were to compare and make correlations between age and Doppler parameters of the interlobar arteries, including synchronously obtained plasma renin and aldosterone levels and to obtain new normative data regarding acceleration time in healthy children from neonates to 16 years.

Subjects And Methods: One hundred sixty-nine healthy children (72 girls and 97 boys) were classified into four groups: group 1 (< 1 year; n = 34), group 2 (range, 1-6 years; n = 48), group 3 (range, 6-12 years; n = 50), and group 4 (range, 12-16 years; n = 37). Blood samples from the renin and aldosterone were collected in the morning after bed rest and fasting.

Occupational prolonged organic solvent exposure in shoemakers: brain MR spectroscopy findings.

Our purpose was to investigate, by magnetic resonance (MR) spectroscopy, the metabolite changes in the brains of subjects in the shoemaking industry who had been chronically exposed to organic solvents. A total of 49 male subjects and 30 age-matched healthy volunteers underwent detailed neurological and psychiatric examinations. All subjects had long-echo [repetition time (TR) 2000 ms, echo time (TE) 136 ms] single-voxel MR spectroscopy.

[Associated brain anomalies and clinical findings in corpus callosum dysgenesis].

Purpose: The aim of this study was to evaluate the relationship between the types of the corpus callosum dysgenesis, the associated brain anomalies and clinical findings.

Materials And Methods: We analyzed the MR imaging findings in 169 patients with callosal dysgenesis. Corpus callosum dysgenesis was categorized into agenesis, hypogenesis and hypoplasia.
