13. Prolonged survival after surgical resection of cerebral metastasis from melanoma with multisystemic metastasis already present: a case report and literature review
ABSTRACT CONTEXT: Malignant melanoma is the third most common cause of cerebral metastases after breast and lung cancer. Despite advances in therapeutic options, the prognosis for patients with cerebral metastases from melanoma remains poor, with a median survival time of six months after diagnosis. CASE REPORT: A 65-year-old woman was diagnosed with a mal

14. Bacterial translocation and mortality on rat model of intestinal ischemia and obstruction
Abstract Purpose: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival. Methods: After anesthesia, Wistar rats was subject to laparotomy, intestinal ischemia and obstruction through an ileal l

15. Effect of aqueous extract of the leaves of Baccharis trimera on the proliferation of hepatocytes after partial hepatectomy in rats
Abstract Purpose: To evaluate the effect of aqueous extract of Baccharis trimera leaves on the proliferative capacity of the liver after partial hepatectomy (PH) in rats. Methods: Twenty Wistar rats weighing between 300 and 450g were divided into two groups: control (HP) and test (HP100-rats that received the aqueous extract of Baccharis trimera for four d

16. New concepts and outcomes for children with hepatoblastoma based on the experience of a tertiary center over the last 21 years
OBJECTIVE: The aim of this study was to summarize the experience of a tertiary center in treating hepatoblastoma for the last 21 years. PATIENTS AND METHODS: Fifty-eight cases were included. The tumor extent and prognosis were assessed using the PRETEXT system. The following data were analyzed: age at diagnosis, comorbidities, prematurity, treatment modali

17. Effect of cyclosporine on liver regeneration in partial hepatectomized rats
PURPOSE:To evaluate the influence of the cyclosporine in liver regeneration in rats submitted to an experimental model of 70% hepatectomy.METHODS: Forty male rats were randomly divided in four subgroups (C.24h, C.7d, E.24h, E.7d), according to the drug used and the day of sacrifice (24 hours and 7 days). Cyclosporine (10mg/Kg/day) was given to the study subg

18. Preoperative imatinib for patients with primary unresectable or metastatic/recurrent gastrointestinal stromal tumor
OBJECTIVES: Despite its rising popularity, reports on the use of preoperative imatinib mesylate (IM) in patients with advanced gastrointestinal stromal tumor (GIST) are limited. This study aims to explore the clinical efficacy of preoperative IM in patients with primarily unresectable or metastatic/recurrent GIST. METHODS: Between September 2009 and Febru

19. Evaluation of liver regeneration with use of diet supplemented with l-arginine
PURPOSE:To compare controlled liver regeneration in rats submitted to 60% hepatic resection having L-arginine supplemented diet, based on weight changes of the regenerated liver, laboratory parameters of liver function and pathological findings.METHODS:Thirty-six rats were divided into two groups, control and L- arginine. The first received standard chow and

20. Laparoscopic resection of tumor recurrence after radical nephrectomy for localized renal cell carcinoma
Introduction Local recurrence of Renal Cell Carcinoma (RCC) after radical nephrectomy is a rare event. Some known risk factors are: clinical/pathological stage, locorregional disease and lyimph node positivity. Since up to 30-40% of patients can achieve a disease-free status, we show a case (video) in which we performed a laparoscopic excision of a local RCC

21. The ileum positively regulates hepatic regeneration in rats
PURPOSE: To test the hypothesis that liver regeneration after partial hepatectomy can be influenced by the ileum.METHODS:Eighteen Wistar rats were distributed into groups of six animals: 1 - ileum resection+ hepatectomy 2/3; 2 - hepatectomy 2/3, and 3 - sham. Anesthesia with ketamine and xylazine i.p., aseptic technique, analgesia with meperidine (10mg/kg s.

22. Superoxid dismutase activity in portal vein endothelium after partial liver resection
PURPOSE: To investigate superoxide dismutase (SOD) activity in the portal vein endothelium and malondialdehyde acid (MDA) production in liver tissue of rats submitted to 70% hepatectomy. METHODS:Twelve rats were distributed in two groups (hepatectomy and sham). Animals were sacrificed on post operative day 1 and portal vein, liver tissue and blood samples we

24. The ileum as a determinant organ of the functional liver cell mass in rats
PURPOSE: To evaluate if the ileum resection changes the functioning liver cell mass, the hepatic metabolism and the biodistribution of radiopharmaceutical in rats. METHODS: Twelve Wistar rats weighing 285g±34g were randomly divided into the ileum resection group (n = 6) and sham group rats (n = 6). After 30 days, they were anesthetized and 0.1mL of 99m-Tc-p
