Pylephlebitis due to perforated appendicitis in a teenager.

Pylephlebitis, a septic thrombophlebitis of the portal vein, is a life-threatening complication of intraabdominal infections, commonly associated with acute appendicitis in children, and diverticulitis in adults. A 13-year-old boy was admitted for high fever and jaundice. On the fifth day of hospitalization, ultrasound Doppler flow and Computer Tomography scan studies showed thrombosis of the portal vein and acute appendicitis.

Congenital midline cervical skin bridge: a case report.

A skin bridge extending from the hyoid region to the sternal notch in a 3-month-old baby is reported as another form of congenital midline neck anomaly that has never been described before. Congenital midline neck anomalies are residual embryonic structures that had failed to completely disappear or mature. They can be classified into masses, clefts, and fistulas.

[Open versus laparoscopic appendectomy in children in a regional hospital in Israel].

Unlabelled: Although laparoscopic appendectomy (LA) has already been found to be associated with greater diagnostic accuracy, less post-operative pain and shorter hospital stay as compared to open appendectomy (OA), questions remain regarding the advantages of this approach and it is still not widely practiced in children, especially in regional hospitals.

Aim: This study aims to evaluate Ha'emek Medical Center's initial experience with pediatric OA and LA between July 2002 and October 2003.

Methods: This study is a retrospective outcome analysis of pediatric OA and LA.

Effects of enteral arginine supplementation on the structural intestinal adaptation in a rat model of short bowel syndrome.

The nitric oxide precursor L-arginine (ARG) has been shown to influence intestinal morphology and intestinal absorptive function. The purpose of the present study was to determine the effect of enteral ARG supplementation on structural intestinal adaptation, cell proliferation, and apoptosis in a rat model of short bowel syndrome (SBS). Thirty male Sprague-Dawley rats were divided into three experimental groups: Sham rats underwent bowel transection, SBS rats underwent 75% small bowel resection, and SBS-ARG rats underwent bowel resection and were treated with ARG given in the drinking water (2%).

Peptide growth factors and intestinal adaptation in short bowel syndrome.

Intestinal adaptation is the term applied to progressive recovery from intestinal failure following a loss of intestinal length. The regulation of intestinal adaptation is maintained through a complex interaction of many different factors. These include nutrients and other luminal constituents, hormones, and peptide growth factors.

Effect of transforming growth factor-alpha on intestinal adaptation in a rat model of short bowel syndrome.

Objective: TGF-alpha has recently been shown to stimulate enterocyte proliferation. In the present study we investigated the effect of TGF-alpha on enterocyte proliferation and loss via apoptosis and its effects on intestinal adaptation in a rat following massive bowel resection.

Methods: Male Sprague-Dawley rats underwent bowel transection and reanastomosis (sham group) or 75% small bowel resection and anastomosis (SBS group) and were treated with intraperitoneal TGF-alpha (75 microg/kg) from the ninth postoperative day (SBS-TGF-alpha group).

Divergent effects of oxygen therapy in four models of uncontrolled hemorrhagic shock.

Treatment with oxygen exerts beneficial effects and prolongs survival in hemorrhagic shock induced by controlled bleeding. We evaluated the effects of inhalation of 100% oxygen in four models of uncontrolled bleeding in rats: amputation of the tail, laceration of two branches of the ileocolic artery, incision of the spleen, and laceration of the lateral lobe of the liver. After tail amputation, oxygen caused a short and transient increase in mean arterial blood pressure (MABP; P < 0.

Sandostatin impairs postresection intestinal adaptation in a rat model of short bowel syndrome.

Because of its antisecretory properties, sandostatin has been advocated for the treatment of patients with short bowel syndrome (SBS). This study was conducted to determine the effect of sandostatin on structural intestinal adaptation, cell proliferation and apoptosis in a rat model of SBS. Sprague-Dawley rats were divided into three experimental groups: Sham rats underwent bowel transection, SBS rats underwent 75% small bowel resection, and SBS-sandostatin rats underwent bowel resection and were treated with sandostatin (SBS-SND).
