Does Helium Pneumoperitoneum Reduce the Hyperinflammatory Response in Septic Animals during Laparoscopy?

Unlabelled: . An exacerbated reaction to peritoneal infection and attendant surgical procedures is characterized by an intense hyperinflammatory state, the magnitude of which is proportional to the severity of tissue injury. Laparoscopy generates lower levels of tissue damage compared with open surgery and should induce less pronounced immune responses.

Isolation and identification of Candida species in patients with orogastric cancer: susceptibility to antifungal drugs, attributes of virulence in vitro and immune response phenotype.

Background: Because of the inherent immunosuppression of cancer patients opportunistic infections by Candida spp, occur frequently. This study aimed to identify Candida species in the oral mucosa of 59 patients with orogastric cancer (OGC) and to analyze the immunological phenotype of these patients.

Methods: The yeasts were identified by MALDI-TOF mass spectrometry (MS).

Chlorhexidine as a factor that promotes peritoneal adhesions in rats with induced peritonitis.

Purpose: To investigate the effects of chlorhexidine on the formation of adhesions and dilation of the colon at the oral end of anastomosis in the presence of peritonitis.

Methods: Peritonitis was induced in male Wistar rats by cecal ligation and puncture (CLP). Abdominal cavities were irrigated with tepid solutions containing 0.

[Visceral leishmaniasis: retrospective study on factors associated with lethality].

Introduction: Visceral leishmaniasis is a public health problem, with lethality reaching 10%. The recommended drug treatment is methylglucamine antimoniate. This study aimed to evaluate drug use for cases of visceral leishmaniasis treated at the Infectology Clinic of the Campo Grande University Hospital Center, State of Mato Grosso do Sul.

Clinical and histological responses to laparoscopically-induced peritonitis in rats.

Purpose: To evaluate the efficacy of inducing peritonitis in rats through laparoscopic cecal ligation (CL), by means of an elastic band.

Methods: Twelve Wistar rats were subjected to cecal ligated with an elastic band applied using a specially constructed applicator. In six of the animals (the CL group) the cecal sac was preserved intact whilst in the remaining animals (the CLP group) the sac was perforated with scissors.
