Helicobacter pylori infection in gastric cancer: A study of 84 cases from Asir Region.
Gastric cancer can be divided into three histologic types: intestinal and diffuse adenocarcinoma, and malignant lymphoma. To determine whether Helicobacter pylori was associated with either cancer type, we reviewed histologic sections from stomachs of 84 patients with the diagnosis of gastric. Of 63 patients with histologic evidence of intestinal adenocarcinoma, 53 (84%) contained H. pylori n noncancerous tissue compared with six (66.7%) of nine patients with diffuse adenocarcinoma (odds ratio = 2.65; Z=1.048; P>0.05) and with eight (66.7%) of 12 patients with non-Hodgkin malignant lymphoma of the stomach (odds ratio = 2.65; Z=0.826; P>0.05). Our findings are compared with reported data from other countries and we are not aware of similar reports from the Kingdom of Saudi Arabia.

With an increase in travel to tropical countries, the need to improve the disease-risk perceptions of travelers who are either naive or given inappropriate or ineffective advice is becoming increasingly important. More widely available, specialized centers that can provide advice on tropical or travel-related diseases have been established, but their efficacy on travelers' knowledge and health has not been verified. Therefore, this study was undertaken to evaluate the impact of the service provided by a routine travel consultation at the Hospital for Tropical Diseases Travel Clinic, London, England. ⋯ Our results show that a face-to-face interview for an average of 18 minutes by trained staff is an effective way of improving travelers' knowledge on certain topics. The slight improvements overall are explained by the levels of experience of travel and previously acquired knowledge of the clients in our study. Effective advice on malaria prevention and some health risks is given during an average consultation; however, there is still a need for improvement in giving information on the management of diarrhea, fever, and other travel diseases.

From 1985 to 1990, the CFC has monitored the growing national epidemic of Lime disease, which appears to parallel increased public awareness and knowledge of Lyme disease. Cases have now been reported from all 50 states, but the national surveillance program has been hampered by persistent confusion between the two diseases, with clinicians frequently reporting a case of Lime disease as Lyme disease. Analysis of surveillance reports of cases fulfilling the case-definition of Lime disease indicates that Lime disease is distributed uniformly throughout the United States (in contrast to the focal geographic occurrence of Lyme disease); the...

Right upper abdominal pain in the presence of pelvic inflammatory disease is called Fitz-Hugh-Curtis syndrome. It is due to perihepatitis secondary to transperitoneal spread of Neisseria gonorrhoeae or Chlamydia trachomatis. ⋯ A case history demonstrates how clinical recognition allows effective management before the results of laboratory investigations are available. The Fitz-Hugh-Curtis syndrome is readily treated with conventional antibiotic regimens.
