Ectopic location of the ampula of Vater within the pyloric channel

The ampulla of Vater is commonly located in the posteromedial wall of the second portion of the duodenum. At times, the ampulla of Vater may be found at uncommon sites such as the third and fourth portions of the duodenum, the duodenal bulb and the stomach. We found the ampulla of Vater in the pyloric channel in a 44 year old patient who had undergone surgery for acute cholecystitis. An intra-operative T-tube cholangiography revealed distal narrowing. The major papilla was not found during endoscopic retrograde cholangiopancreatography [ERCP] and a more accurate T-tube cholangiography revealed that the common bile duct opened in the distal stomach, probably in the pylorus. Finally the ampulla opening was located in the pylorus by methylene blue injection through the T-tube at endoscopy. This rather unusual location of the ampulla of Vater has implications for gastroenterologists performing ERCP

Bacterial etiology of diarrhea in children in Alexandria

This study included 470 infants and young children below 6 years of age suffering from diarrhea. E. E. C. were isolated from 5.9% of the cases, Salmonella from 2.5%, Shigella from 9.4%, Vibrio from 0.4% and Campylobacter jejuni from 15.1%. Yersinia enterocolitica was not isolated from any of cases

Prevalence and antibiotic sensitivity of haemophilus influenzae in the upper respiratory tract of individuals living in a rural agrarian community

The carrier rate of H. influenzae in the nasopharynx of individuals living in a rural agrarian community using a selective bacitracin chocolate agar was 53.9% and was highest in the age group 1-3 years reaching 78.79%. The strains were sensitive to Cephalothin, Chloramphenicol, Erythromycin, Gentamycin, Kanamycin, Neomycin, Polymyxin B, Streptomycin and Tetracycline. Only one strain was resistant to Ampicillin. All strains were resistant to Troleandomycin and Vancomycin

Screening of blood donors for hepatitis antigen [HBs] and anti-HBs at Alexandria, El-Shatby blood bank

2000 paid blood donors at the El-Shatby Blood Bank, Alexandria, were screaned for HBs antigen and Anti-HBs, using the counter immunoelectrophoresis technique. HBs Ag was detected in 3.25, while Anti-HBs was detected in 3%. Correlation between the HBs Ag and antibody was found to be statistically insignificant when related to age, blood group and the presence or absence of Rh. antigen. Meanwhile the presence of the hepatitis antigen and antibody was found to be highly significant when related to the number of previous donations. Chronic carrier state was reported in 2.5% of the donors
