SOLID PSEUDOPAPILLARY NEOPLASM OF THE PANCREAS.

Background: The solid pseudopapillary neoplasm is a rare tumor of the pancreas. However, it´s etiology still maintain discussions.

Aim: To analyze it´s clinical data, diagnosis and treatment.

Tamoxifen decreases the myofibroblast count in the healing bile duct tissue of pigs.

Objective: The aim of this study was to evaluate the effect of oral tamoxifen treatment on the number of myofibroblasts present during the healing process after experimental bile duct injury.

Methods: The sample consisted of 16 pigs that were divided into two groups (the control and study groups). Incisions and suturing of the bile ducts were performed in the two groups.

Severe acute pancreatitis: results of treatment.

Objective: To evaluate the results of the Protocol for treatment of patients with severe acute pancreatitis.

Methods: We consecutively analyzed age, gender, etiology, length of hospital stay, type of treatment and mortality of 37 patients with severe acute pancreatitis from January 2002.

Results: The patients' ages ranged from 20 to 88 years (average 50 years), 27% were female and 73% male.

Castleman's disease mimetizing pancreatic tumor.

Context: Angiofollicular lymph node hyperplasia or Castleman's disease is a rare clinical condition. Knowledge about etiology and physiopathology; and treatment management as well are yet to be defined. Unicentric presentation of this disease affecting single lymph nodes in the mediastinum seems to be the most common presentation.

The repercussions of spinal cord injury on the action of the diaphragmatic crura for gastroesophageal reflux containment.

Study Design: Cross-sectional and nonexperimental.

Objective: To detect and compare functional abnormalities in the esophagus and esophagogastric junction in 2 groups with chronic spinal injuries, 1 with injuries at the phrenic innervation level and the other at upper thoracic levels, and to relate these to gastroesophageal reflux containment.

Summary Of Background Data: There are no studies on esophageal manometry with pH metering among spinal cord injury patients.

Endoscopic treatment of bleeding gastric varices using large amount of N-butyl-2-cyanoacrylate under fluoroscopic guidance.

Purpose: We propose the use of fluoroscopic guidance for endoscopic injection of n-butyl-2-cyanoacrylate to treat gastric variceal hemorrhage to achieve placement of the safest quantity of tissue adhesive.

Methods: Ten patients with gastric varices were treated with n-butyl-2-cyanoacrylate endoscopic injection under fluoroscopic guidance for the purpose of hemostasis or prevention of recurrent bleeding. The glue was infused into the varices in the quantities needed to achieve complete obliteration of the gastric varices.

Hypertonic glucose solution 10%-25% on the mesenterium and peritoneum of the rat: macroscopic and microscopic study.

Purpose: The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat.

Methods: 90 Wistar females young rats adults were used weighing between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0.

[Bacteremia -- prevalence and associated factors in patients with acute calculous cholecystitis].

Background: Bacteremia seems to increase the morbidity and mortality in clinical and surgical conditions, however the importance and factors associated with it during acute calculous cholecystitis are not well established. The purpose of this study was to determine pre-operative prevalence, associated factors and prognosis of bacteremia in patients with acute calculous cholecystitis submitted to an emergency cholecystectomy.

Methods: A prospective study of 51 patients with histological diagnosis of acute calculous cholecystitis was designed.
