Afghanistan has 2 tuberculosis surveillance systems, the National Tuberculosis Control Programme (NTP) and the Health Management Information System (HMIS). An evaluation of these surveillance systems in January/ February 2010 was done to identify their strengths and weaknesses and to formulate recommendations. Attributes of the programmes were evaluated using US Centers for Disease Control and Prevention guidelines. Usefulness and flexibility of the NTP system were good; stability, representativeness and data quality were average. Simplicity, acceptability and timeliness were poor. Reporting delays regularly exceeded 3 months. Positive predictive value and sensitivity were 11% and 70% respectively. The HMIS system was simple, acceptable and stable, with timely reporting. Reporting and feedback were good, as this system has strong government support. Flexibility, data quality and representativeness were average. Positive predictive value and sensitivity were 10% and 68% respectively. No outbreaks were detected by either system. The NTP and HMIS surveillance systems are duplicative and neither covers the private sector. [ABSTRACT FROM AUTHOR]

Gastric cancer is the second most common cause of cancer death in the world. Helicobacter pylori infection is now a well-accepted cause of this malignancy; in some parts of the world, up to eighty percent of all gastric cancers are at least in part caused by H. pylori infection. H. pylori infection typically starts in childhood as an inflammatory process in the stomach. The changes in the gastric microenvironment facilitate gastric cancer over time. Among infected individuals, genotype of H. pylori, coincident environmental exposures, and genetic factors of host seem to play roles in determining who will get gastric cancer and who will not. Unfortunately, it remains unknown whether treatment of H. pylori prevents gastric cancer. Thus, screening for H. pylori to prevent cancer is not yet widely recommended. Some consensus groups, however, have recommended screening for and treating H. pylori infection in individuals with family histories of gastric malignancy. In high-risk countries, screening programs for early gastric cancer itself may improve therapeutic outcome for this highly lethal disease.
