Recovery of chemical components from Spondias mombin L. leaves using pressurized hot water, ultrasound and turbo-extraction techniques.

The fruit of Spondias mombin (cajazeira) is widely consumed in the northeast region of Brazil. In this work, three different extraction methods, namely ultrasound-assisted extraction (UAE), turbo-extraction (TE) and pressurized hot water extraction (PHWE), were evaluated in order to investigate the potential of cajazeira leaves as an alternative source of bioactive compounds. The extraction methods were compared in terms of yield, chemical composition and total phenolic content (TPC) of the extracts.

Laparoscopic Prophylactic Total Gastrectomy for Hereditary Diffuse Gastric Cancer in Mutation Carriers.

Patients with hereditary diffuse gastric cancer (HDGC) and germline mutations in the E-cadherin gene, , have a very high cumulative lifetime risk of developing diffuse gastric cancer. In these patients, it is formally recommended to perform a prophylactic total gastrectomy (PTG). We analyzed the course of patients with HDGC who have undergone PTG in our institution.

Laparoscopic Heller Myotomy and Roux-en-Y Gastric Bypass as Treatment for Patients with Achalasia and Morbid Obesity: Outcomes in a Short Series of Patients.

The association between morbid obesity and esophageal achalasia is very infrequent. However, over the last decade, these cases started to increase because of the disturbing rise of morbid obesity worldwide. Heller myotomy (HM) and laparoscopic fundoplication represent the best treatment option for esophageal achalasia.

Non-Bariatric Roux-en-Y Gastric Bypass.

Roux-en-Y gastric bypass (RYGB) is frequently performed for weight loss purposes in the morbidly obese population. The popularity and acceptance of this procedure have increased the knowledge of the physiological (anatomical and functional) changes that this technique produces in the organism. RYGB improves gastric emptying and gastroesophageal reflux symptoms.

Resection of the Gastroesophageal Junction and Roux-en-Y Reconstruction as a New Alternative for the Treatment of Recurrent Achalasia: Outcomes in a Short Series of Patients.

Heller myotomy and laparoscopic fundoplication represents the best treatment option for esophageal achalasia, with effective short- and long-term success. However, treatment options in patients in whom primary surgery failed represent a real challenge. We present the resection of the gastroesophageal junction (GEJ) along with a Roux-en-Y reconstruction as a treatment alternative.

Is selective arthroscopic revision beneficial for treating recurrent anterior shoulder instability?

Background: Surgeons have traditionally treated recurrent shoulder dislocation by open methods. With the advent of arthroscopic repair techniques some surgeons reported higher recurrence rates than with open methods but some of those reports included patients with a variety of problems, including bone loss and those continuing in contact sports. It is unclear whether recurrence rates would be higher in patients without bone loss and those willing to forego contact sports.

[Mediastinis related to esophagogastric disease and injury. Warning clinical signs and independent predictors of intrahospitalary survival].

Objective: To identify clinical warning signs and independent predictors of survival in mediastinitis related to esophagogastric diseases and injuries.

Methods: From March 1998 to February 2009, 36 patients with a mean age of 55.7 +/- 12.
