A Horned Viper Bite Victim with PRES.

Neurological complications of snake bites have been well documented in the literature as neuromuscular paralysis and cerebrovascular complications; posterior reversible encephalopathy syndrome was rarely described. A 23-year-old lady presented near full term of her pregnancy with a horned snake bite; after successful delivery she started complaining of altered mental status and visual disturbance with ulceration over the site of the snake bite. On admission, the patient had Glasgow Coma Score of 12, blood pressure 130/80 mmHg, temperature 38°C, sinus tachycardia at 120 beats per minute, severe dehydration, and reduction in visual acuity to "hand motion" in both eyes with poor light projection and sluggish pupillary reactions.

Evolution of living donor liver transplantation in Egypt.

Objective: To date, cadaveric organ donation is illegal in Egypt. Therefore, Egypt recently introduced living donor liver transplantation (LDLT), aiming to save those who are suffering from end stage liver disease. Herein, we study the evolution of LDLT in Egypt.

Systemic and cell-mediated immune response after laparoscopic and open cholecystectomy in patients with chronic liver disease. A randomized, prospective study.

Background: As impaired immune function observed in cirrhotic patients is known to increase the risk of postoperative complications, the immunological response to surgery was investigated.

Methods: Twenty-eight patients with postnecrotic liver cirrhosis or chronic hepatitis C and symptomatic gallstone disease were randomly allocated to laparoscopic (LC) or open cholecystectomy (OC). Changes in concentrations of cytokines (TNF-alpha, IL-1beta, IL-6, IL-8 and IL-10) were followed and the effect of surgical trauma on the distribution of lymphocyte subpopulations (CD3, CD4, CD8, CD16 and CD19) and NK cell cytotoxicity were measured.

Postoperative hepatic catabolic stress response in patients with cirrhosis and chronic hepatitis.

Open (OC) or laparoscopic (LC) cholecystectomy is considered a relative contraindication in patients with liver cirrhosis. The effect of LC and OC on the hepatic catabolic stress response was studied in patients with postnecrotic liver cirrhosis and chronic hepatitis to define the most suitable procedure from a metabolic point of view. Altogether 14 patients with cirrhosis and 14 with chronic hepatitis were randomized to LC or OC (n = 7 in each group).

Biliary parasites.

Parasitic diseases of the biliary tract occur frequently in tropical and subtropical areas and cause high morbidity and mortality. In general, neither the clinical presentation nor the general laboratory findings are sufficiently unique to raise the possibility of a parasitic biliary infestation in the mind of the surgeon. Once considered, however, the presence of a parasitic biliary infestation is easily confirmed.
