Experimental evaluation of the use of starch and carboxymethylcellulose in the prevention of intraperitoneal adhesions in hernia surgery with coated meshes.

Purpose: Laparoscopic hernia repair involves a risk of adhesion between coated mesh and viscera. Plant polysaccharides such as starch and carboxymethylcellulose (SC) make up a product that acts as a barrier and prevents intraperitoneal adhesions. This study aimed to evaluate whether topical SC can also reduce adhesions between mesh and intra-abdominal organs.

Profile of potential organ donors and factors related to donation and non- donation of organs in an Organ Procurement Service.

Objective: to characterize the profile of potential and effective organ donors, and to identify the factors related to non-donation.

Methods: the data was collected from the Organization of Organ Donation forms during the period of January 2013 to April 2018. The statistical analysis was done by the Biostatistic Service of the School of Medical Sciences of UNICAMP.

Predictors of chest drainage complications in trauma patients.

Objective: to identify predictors of chest drainage complications in trauma patients attended at a University Hospital.

Methods: we conducted a retrospective study of 68 patients submitted to thoracic drainage after trauma, in a one-year period. We analyzed gender, age, trauma mechanism, trauma indices, thoracic and associated lesions, environment in which the procedure was performed, drainage time, experience of the performer, complications and evolution.

Extrahepatic duct injury in blunt trauma: two case reports and a literature review.

Traumatic injuries of the extrahepatic biliary tract are rare. Associated injuries are usually responsible for immediate indication for surgical treatment, the time when an injury to the extrahepatic biliary ducts may be diagnosed. However, missed injuries are often common.

Update in the classification and treatment of complex renal injuries.

The "Evidence-Based Telemedicine - Trauma and Acute Care Surgery" (EBT-TACS) Journal Club performed a critical review of the literature and selected three up-to-date articles on the management of renal trauma defined as American Association for the Surgery of Trauma (AAST) injury grade III-V. The first paper was the proposal for the AAST grade 4renal injury substratification into grades 4a (Low Risk) and 4b (High Risk). The second paper was a revision of the current AAST renal injury grading system, expanding to include segmental vascular injuries and to establish a more rigorous definition of severe grade IV and V renal injuries.

Blunt hepatic trauma: comparison between surgical and nonoperative treatment.

Objective: To examine the outcomes of blunt hepatic trauma, and compare surgical and non-surgical treatment in patients admitted with hemodynamic stability and with no obvious indications of laparotomy.

Methods: This is a retrospective study of cases admitted to a university teaching hospital between the years 2000 and 2010. Patients undergoing surgical treatment were divided into two groups: (a) all patients undergoing surgical treatment, and (b) patients with obvious need for surgery.

Plain chest radiographs for the diagnosis of post-traumatic diaphragmatic hernia.

Objective: To describe changes in the radiographic examination of the chest in patients with post-traumatic diaphragmatic hernia (PTDH) confirmed intra-operatively.

Methods: Between January 1990 and August 2008 45 patients with PTDH were treated. We analyzed demographic data, cause of injury, changes in chest radiography (CXR), extent and location of the diaphragmatic lesion and herniated organs.

Total hepatic ischemia and reperfusion after state controlled hemorrhagic shock, with used of different solutions: effects of neutrophils sequestration in kidney of rats.

Purpose: To evaluate and compare neutrophils sequestration in the renal cortex of rats, result of total hepatic ischemia and reperfusion after controlled hemorrhagic shock, with use of different electrolytic solutions.

Methods: Used 18 rats Wistar, males, adult, divided into three groups as the solution used to reanimation: Group PSS: physiologic saline solution; Group HSS: hypertonic saline hypertonic (7.5%) followed by lactated ringer's solution; Group LRS: lactated ringer's solution.

[Total hepatic ischemia and reperfusion under normal conditions and submitted to controlled hemorrhagic shock state: effects of neutrophil sequestration in kidney of rats].

Purpose: The evaluate the effects of total hepatic ischemia and reperfusion under normal conditions and submitted to controlled hemorrhagic shock state on the accumulation of neutrophils in the cortex renal of rats.

Methods: In this experiment 32 male adult Wistar mice, were divided into four groups: Control Group (CG), submitted to the catheterizations and laparotomy, followed by a period 60 minutes of observation; Shock Group (SG): controlled of hemorrhagic shock (CHS) for 20 minutes (20'), mean arterial pressure (MAP) 40 mmHg, followed by reanimation and reperfusion for 60 minutes (RP60); Pringle Group (PG): Pringle's Maneuver (PM) for 15 minutes (15'), followed for RP60'; Shock-Pringle Group (SPG): CHS (MAP = 40 mmHg) for 20' followed by laparotomy and PM for 15', followed for RP60'. To characterize the poor tissular perfusion blood lactate and the base reserve were measured.

Investigating the relationship between hemodynamic and metabolic parameters in portal triade occlusion following hemorrhagic shock.

Purpose: To determine whether metabolic and hemodynamic parameters are "mathematically" coupled in rats submitted to portal triad occlusion following controlled hemorrhagic shock state.

Methods: Pearson's coefficient (r-value) analysis was performed. Differences considered significant at p < 0.
