The utility of intraperitoneal drain placement after laparoscopic appendectomy for perforated appendicitis in postoperative intraperitoneal abscess prevention.

Background: Perforated appendicitis is associated with postoperative development of intraperitoneal abscess. Intraperitoneal drain placement during appendectomy is thought to reduce the risk of developing postoperative intraperitoneal abscess. The aim of this study was to determine whether intraperitoneal drainage could reduce the incidence of intraperitoneal abscess formation after laparoscopic appendectomy for perforated appendicitis.

Tumor necrosis factor (TNF) induces astrogliosis, microgliosis and promotes survival of cortical neurons.

Objectives: Neuro-inflammation occurs as a sequence of brain injury and is associated with production of cytokines. Cytokines can modulate the function and survival of neurons, microglia and astrocytes. The objective of this study is to examine the effect of TNF on the neurons, microglia and astrocytes in normal brain and stab wound brain injury.
