OBJECTIVE To evaluate the patterns of pulmonary venous drainage into the left atrium and to determine the frequency of each variant of pulmonary venous anatomy. MATERIALS AND METHODS After institutional review board approval (No. 09JUL011148), 300 studies of thoracic multidetector computed tomography were retrospectively reviewed for the anatomical features of the pulmonary vein and its drain...

designing effective strategies for sediment management and control is closely related to identification of sediment sources in a drainage basin. one of the methods for investigating sediment sources is using magnetic tracers for erosion and sediment yield studies. sediment source identification using magnetic characteristics is a simple, inexpensive, quick and non-destructive method having appl...

conclusions trim22 gene ring domain -364t/c polymorphism is associated with chronic hbv infection in chinese han population. results 243 (31.76%) of 765 chinese han patients showed genetic variation in the trim22 gene. trim22 snps were mainly in ring area -364t/c site, accounting for 98.35% of the population. there were no significant differences (p > 0.05) in the ring domain -364t/c snp and al...

BACKGROUND The prognostic significance of multiple draining basins is controversial in melanoma because analyses have not adequately controlled for standard prognostic variables. We hypothesized that an analysis based on prognostically matched pairs of patients with multiple versus single drainage basins would clarify any independent role of basin number. STUDY DESIGN We identified patients i...

background: historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. the records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. methods: the clinical features, laboratory tes...

concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...

Variations of the gonadal vein involve especial interest in general, vascular, and renal transplant surgery [1]. The testicular drainage originates at the upper pole of the testis, through the pampiniform plexus, which travels alongside the spermatic cord. The origin of the testicular vein, on both sides, lies at the deep inguinal ring, following a cephalic retroperitoneal path along the Psoas ...

OBJECTIVE To evaluate the results of chest drainage using one 24F Blake drain after standard thoracic operations (wedge resection and lobectomy). METHODS In 2005, 100 consecutive patients underwent drainage of their pleural cavity following lobectomy or wedge resection(s). There were 70 men and 30 women, with a mean age of 55 years (17-83). There were 47 lobectomies (23 upper, 5 middle, 19 lo...

Case History A 57-year-old female presented to her local hospital with a 2-month history of retrosternal discomfort that was initially diagnosed as esophageal spasm. She had progressive symptoms, had regurgitation of food, and underwent upper gastrointestinal endoscopy. The stomach appeared grossly abnormal and had the morphological appearances of linitis plastica. Staging computed tomography (...
