    11 beta-Hydroxysteroid Dehydrogenase Type 1 is Overexpressed in Subcutaneous Adipose Tissue of Morbidly Obese Patients
    (SPRINGER, 2009) Munoz, Rodrigo; Carvajal, Cristian; Escalona, Alex; Boza, Camilo; Perez, Gustavo; Ibanez, Luis; Fardella, Carlos
    11 beta-Hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) enzyme catalyzes interconversion of inactive cortisone to active cortisol. Its expression in adipose tissue has been associated with obesity and some of its metabolic disorders. Controversies regarding which fat depots [subcutaneous adipose tissue (SAT) or visceral adipose tissue (VAT)] have higher expression still remain. The aim of this work was to evaluate 11 beta-HSD1 expression in SAT and VAT of obese patients and evaluate its association to metabolic features of metabolic syndrome.

    INTESTINAL PERFORATION SECONDARY TO BLUNT INGUINAL TRAUMA IN A SOCCER PLAYER: A CASE REPORT
    (ELSEVIER SCIENCE INC, 2012) Vucetich, Nevenka; Andresen, Max; Hasbun, Pablo; Regueira, Tomas; Ibanez, Luis; Gonzalez, Alejandro
    Background: Intestinal perforation caused by blunt trauma to an inguinal hernia is a very uncommon event. Case Report: We present the case of a 55-year old man who suffered trauma to the inguinal area while playing soccer and later developed intense abdominal pain with no categorical signs of peritoneal irritation. Computed tomography scan at arrival showed a right inguinal hernia, with partial protrusion of the ileum, inflammatory changes of the mesenteric fat tissue inside the hernial sac, and free intraperitoneal fluid. Several hours later he developed hypotension and fever. An emergency laparotomy was performed, revealing ileum perforation with peritonitis. Intestinal perforation was repaired without intestinal resection. After surgery, the patient developed severe septic shock with multiple organ failure. He recovered without sequelae and was discharged 3 weeks later. Conclusion: This case emphasizes the potential clinical complications associated with this condition. (C) 2012 Elsevier Inc.

    Laparoscopic Sleeve Gastrectomy as a Stand-Alone Procedure for Morbid Obesity: Report of 1,000 Cases and 3-Year Follow-Up
    (SPRINGER, 2012) Boza, Camilo; Salinas, Jose; Salgado, Napoleon; Perez, Gustavo; Raddatz, Alejandro; Funke, Ricardo; Pimentel, Fernando; Ibanez, Luis
    Laparoscopic sleeve gastrectomy (LSG) is an emerging surgical technique with encouraging results. The objective of this study is to report surgical results after 1,000 consecutive LSG cases as a stand-alone procedure for morbid obesity during a 3-year follow-up.

    Serial analysis of gene expression identifies connective tissue growth factor expression as a prognostic biomarker in gallbladder cancer
    (AMER ASSOC CANCER RESEARCH, 2008) Alvarez, Hector; Corvalan, Alejandro; Roa, Juan C.; Argani, Pedram; Murillo, Francisco; Edwards, Jennifer; Beaty, Robert; Feldmann, Georg; Hong, Seung Mo; Mullendore, Michael; Roa, Ivan; Ibanez, Luis; Pimente, Fernando; Diaz, Alfonso; Riggins, Gregory J.; Maitra, Anirban
    Background: Gallbladder cancer (GBC) is an uncommon neoplasm in the United States, but one with high mortality rates. This malignancy remains largely understudied at the molecular level such that few targeted therapies or predictive biomarkers exist.

    Splenic rupture following colonoscopy
    (BAISHIDENG PUBLISHING GROUP INC, 2008) Francisco Guerra, Juan; San Francisco, Ignacio; Pimentel, Fernando; Ibanez, Luis
    Colonoscopy is a safe and routinely performed diagnostic and therapeutic procedure for different colorectal diseases. Although the most common complications are bleeding and perforation, extracolonic or visceral injuries have also been described. Splenic rupture is a rare complication following colonoscopy, with few cases reported. We report a 60-year-old female who presented to surgical consultation 8 h after a diagnostic colonoscopy. Clinical, laboratory and imaging findings were suggestive for a massive hemoperitoneum. At surgery, an almost complete splenic disruption was evident, and an urgent splenectomy was performed. After an uneventful postoperative period, she was discharged home. Splenic injury following colonoscopy is considered infrequent. Direct trauma and excessive traction of the splenocolic ligament can explain the occurrence of this complication. Many times the diagnosis is delayed because the symptoms are due to colonic insufflation, so the most frequent treatment is an urgent splenectomy. A high index of suspicion needs an early diagnosis and adequate therapy. (C) 2008 The WJG Press. All rights reserved.
