This phase III study compared docetaxel and doxorubicin in patients with metastatic breast cancer who had received previous alkylating agent-containing chemotherapy.Patients were randomized to receive an intravenous infusion of 100 mg/m(2) or 75 every 3 weeks for a maximum seven treatment cycles.A total 326 randomized, 165 161 docetaxel. Overall, produced significantly higher rate objective response than did (47.8% v 33.3%; P =.008). Docetaxel was also more active negative prognostic...

Several different methods of teaching laparoscopic skills have been advocated, with virtual reality surgical simulation (VRSS) being the most popular. Its effectiveness in improving performance is not a consensus yet, however. The purpose this study was to determine whether practicing simulator results improved performance.Fifteen medical students recruited for were divided into three groups. Group I (control) did receive any VRSS training. For 10 weeks, group II trained basic (camera...

Background and Purpose: Becoming proficient in laparoscopic surgery is dependent on the acquisition of specialized skills that can only be obtained from specific training. This training could achieved various ways using inanimate models, animal or live patient surgery—each with its own pros cons. Currently, there are substantial data support benefits model initial learning laparoscopy. Nevertheless, whether these extent themselves to moderately experienced surgeons uncertain. The purpose...

Introduction Medical literature is scarce on information to define a basic skills training program for laparoscopic surgery (peg and transferring, cutting, clipping). The aim of this study was determine the minimal number simulator sessions tasks necessary elaborate an optimal virtual reality curriculum. Materials Methods Eleven medical students with no previous experience were spontaneously enrolled. They submitted starting at level 1 (Immersion Lap VR, San Jose, CA), including sequentially...

WBS is an autosomal dominant disorder that includes features such as developmental delay, cardiovascular anomalies, mental retardation and characteristic facial appearance. We systematically investigated the prevalence spectrum of voiding dysfunction in this population.We prospectively evaluated 16 boys 12 girls with WBS, a mean age 9.7 years (range 3 to 19). Urological evaluation included history urinary symptoms impact on quality life, diary, urodynamics radiological tract sonography,...

<b><i>Background/Aims:</i></b> Peritoneal dialysis (PD) has gained interest over the last decade as a viable option for early start dialysis. It is still unknown if shorter break-in periods and less time proper patient evaluation training could influence technique survival in comparison to planned-start PD. <b><i>Methods:</i></b> A prospective observational study that compared cohort of patients who started either or planned Early PD was...

Paragangliomas (PGL) are rare tumors derived from neural crest cells, whose origins may vary along the chain of sympathetic nervous system. Such often characterized by secretion catecholamines, but sometimes they biochemically inactive, which makes diagnosis challenging. Malignant paraganglioma is defined presence this tumor at sites where chromaffin cells usually not found or local invasion primary tumor. Recurrence, either regional metastatic, occurs within 5 years initial complete...
