PURPOSE This study evaluates the effectiveness of total pelvic exenteration with distal sacrectomy for fixed recurrent tumor that developed from primary rectal cancer. METHODS We investigated surgical indications, techniques to minimize blood loss and reduce complications, and oncological outcomes in 57 patients who underwent total pelvic exenteration with distal sacrectomy between 1983 and 2...

BACKGROUND Surgical margin status is an important predictor of risk of relapse among patients with rectal cancer. METHODS Patients referred to the British Columbia Cancer Agency for consideration of adjuvant therapy for rectal adenocarcinoma were included. Predictors of margin positivity were determined from uni- and multivariate analysis. RESULTS Among 340 patients, 83% had negative resect...

Figure 1. Schematic cross sections through (A) Galicia Margin west of Iberian Peninsula (Boillot et al., 1995) and (B) Jurassic margin of Apulian continent toward Alpine Tethys (Manatschal and Bernoulli, 1999). Inset in B displays present location of margin in Swiss Alps and paleoposition of section in Jurassic time. Abbreviations in A: lcc—lower continental crust; man— mantle; S—S-reflector; s...

Colorectal cancer is the third most common cancer, second in women, and fourth leading cause of death world. Radical surgical treatment with Total Mesorectal Excision (TME) considered best for found lower rectum has benefits complete tumor removal to reduce risk recurrence improve survival. Advances preoperative chemoradiation therapy have increased chances achieving a 1 cm distal margin allowe...

Abstract This paper presents findings for active-clamped flyback (ACF) DC-DC converter 57 W used as an auxiliary power-supply of a wireless inductive-charging system 800 V. Measurements magnetizing and leakage inductances three transformers demonstrated how big differences between them could be depending on chosen vendor. Comparison simulated measured Bode plots showed that, even when those wer...

OBJECTIVE One problem existing in breast-conservation surgery is ipsilateral breast tumour recurrence, and one of its major risk factors is surgical margin positivity. We therefore investigated whether total-circumference surgical margin examination can reduce surgical margin-positive rates. METHODS A total of 122 cases were examined after BCS was performed between March 2004 and March 2006. ...

Active ion transport drives iso-osmolar alveolar fluid clearance, a hypothesis originally suggested by in vivo studies in sheep 20 yr ago. Over the last two decades, remarkable progress has been made in establishing a critical role for active sodium transport as a primary mechanism that drives fluid clearance from the distal air spaces of the lung. The rate of fluid transport can be increased i...

[3, 4] . Subsequent work has shown that in appropriately selected cases a distal margin of 10 mm does not increase the local recurrence rate or compromise survival [5] . The lower rectal and anorectal anatomy provides a challenge both from a staging and therapeutic standpoint in rectal cancer. In low rectal cancer (defined as the area below the insertion of the levator muscle), the mesorectal v...

A new species of freshwater crab, Kingsleya celioi, from the Brazilian Amazon (Pará State) is described and illustrated. The new species can be easily separated from their congeners by a suite of morphological characters, including the apical plate of the first gonopod large, widest medially in abdominal view, with single large spine-like outgrowth in midlength of mesial margin; distal, proxima...
