Purpose: To evaluate the usefulness of the Glasgow Prognostic Score (GPS) in patients with esophageal carcinoma (EC).
Methods: A total of 50 patients with EC were analyzed for GPS, nutritional and clinicopathologic parameters. Patients with CRP ≤ 1.
Purpose: To analyze the epidemiological features of patients with esophageal cancer according to the histopathological types: squamous cell carcinoma or adenocarcinoma.
Methods: A total of 100 patients with esophageal cancer, being 50 squamous cell carcinomas and 50 adenocarcinomas were analyzed for demographics, nutritional factors, lifestyle habits, benign pathological conditions associated, like Barrett's esophagus and megaesophagus, tumor stage and survival rates. The nutritional factors evaluated included body mass index, percent weight loss, hemoglobin and albumin serum levels.
Objective: To evaluate the postoperative outcome of patients with pharyngoesophageal diverticulum submitted to surgical and endoscopic treatments.
Methods: We retrospectively analyzed 36 patients with pharyngo-esophageal diverticulum treated at the Hospital of the Medical School of Botucatu - UNESP. Patients were divided into two groups, depending on the treatment: group 1 (n = 24): diverticulectomy associated myotomy through a left cervicotomy; group 2 (n = 12): endoscopic diverticulostomy with linear stapler.
Purpose: To analyze the clinicopathological features and outcome of patients with pathologically proven superficial squamous cell carcinoma of the esophagus.
Methods: A total of 234 consecutive cases of esophageal carcinoma in a 15-year period were reviewed.
Results: Superficial esophageal cancer was found in five patients (2.
Context: In the gastroesophageal reflux disease (GERD), a highly prevalent digestive disorder, gastric content may return to the esophagus and reach the mouth, thus leading to a small number of carious lesions and high incidence of dental erosion. Since saliva plays a major role in oral homeostasis, evaluating salivary parameters is necessary in attempting to explain such outcome.
Objectives: This study aimed at analyzing salivary parameters (salivary flow, pH and buffering capacity), bacterial count, caries index and dental erosion in patients with GERD.
Context: Gastroesophageal reflux disease is a chronic disease in which gastroduodenal contents reflux into the esophagus. The clinical picture of gastroesophageal reflux disease is usually composed by heartburn and regurgitation (typical manifestations). Atypical manifestations (vocal disturbances and asthma) may also be complaint.

The goal of this study was to evaluate the nutritional status of patients with non-advanced megaesophagus in pre and postoperative periods of laparoscopic cardiomyotomy. Ten patients were studied in five moments (pre operative and at 1, 3, 6 and 12 months after surgery).

Hepatobiliary Pancreat Dis Int
April 2009
Background: To physiologically reconstruct the biliary tract, Crema et al suggested the application of the Monti principle to the biliary tract, already used in humans for the urinary tract. With this technique, a jejunal segment is transversely retubularized. This study aimed to evaluate the efficacy of jejunal tube interposition between the common bile duct and duodenum in dogs.
View Article and Find Full Text PDFBackground: The esophagus cancer-host has a two way close relationship as seen in its sulphur-amino acid metabolism. Taurine one of these compounds has ubiquous role in host defense and other physiological mechanisms related to survival.
Aim: To study the plasma levels of taurine and its precursors in patients with esophagus cancer.
Background: The gastroesophageal reflux disease, which has become highly and increasingly incident, may be manifested by typical (pyrosis and regurgitation) and atypical (pulmonary, otorhinolaryngological and buccal) symptoms.
Aim: To analyze alterations in the oral cavity patients with gastroesophageal reflux disease.
Methods: One hundred patients were studied being 50 gastroesophageal reflux disease patients (group 1) and 50 controls (group 2).
Background: Megaesophagus constitutes a public health problem in our country since it affects individuals in the most productive phase of their lives. During the development of the disease, people suffering from it may present association with esophageal cancer.
Aim: To analyze the clinical and epidemiological aspects of patients with megaesophagus and esophageal cancer.
Purpose: To determine podocyte number and GBM thickness in diabetic rats either under glycemic control or without glycemic control at 6 and 12 months after diabetes induction.
Methods: 100 Wistar rats weighing 200-300g were divided into 6 groups: Normal group (N6 and N12- 25 rats); Diabetic group (D6 and D12- 25 rats), diabetic treated group ( DT 6 and DT 12- 25 rats) on insulin 1,8- 3,0 IU/Kg associated with acarbose (50 mg to 100g of food) daily mixed in chow. Alloxan was injected intravenously in a dose of 42 mg/Kg of weight.
Purpose: To determine the number of podocyte, slit diaphragms, slit diaphragm extensions and GBM thickness in diabetic nephropathy.
Methods: Sixty "Rattus Wistar"of both sexes weighing 200-300 g were divided in two experimental groups: normal group 10 animals, and alloxan diabetic rats--50 animals. Alloxan was administered in a single IV dose of 42 mg/kg body weight.
