Typhoid fever still continues to be a major public health problem, particularly in many developing countries. A simple, reliable, affordable and rapid diagnostic test has been a long-felt need of the clinicians. We, therefore,
Entrance surface doses (ESDs) were measured for the most common types of X ray procedures, such as chest PA, lumber spine AP, lumber spine lateral, skull AP, skull lateral and pelvis AP in four major hospitals of Dhaka, the capital city of Bangladesh. Organ/tissue doses for 29 organs/tissues and effective doses for the patients were also calculated using the entrance surface dose as the input quantity. Organ/tissue doses and effective doses were calculated by using XDOSE software based on the Monte Carlo computation method. It was observed that the fluctuation of the entrance surface dose was too large. The ratio of maximum and minimum ESD values ranged from 4.8 to 35.9. Consequently, variation of organ doses was large even in the same type of X ray examination and in the same facility. Mean effective doses for the above mentioned X ray procedures were also determined and compared with the effective doses of some other countries. In most cases effective doses measured for the different types of X ray procedures were found to be lower than the effective doses of some other countries.
Helicobacter pylori is a bacterial infection of the stomach, which plays a major role in abdominal symptoms and gastroduodenal pathology. The pregnant women had a significantly higher relative risk of acquiring H.pylori infection during pregnancy as a result of physiological alterations. To investigate the relationship of H.pylori with dyspeptic symptoms in early and late pregnancy, thirty sera samples were obtained from pregnant women and thirty sera samples were obtained from apparently healthy women as control. All studied groups were evaluated anti-Helicobacter pylori IgG antibody by ELISA. Ten of pregnant women samples (33.3%) were seropositive of anti-H. pylori IgG antibody in pregnant women compared with control. This lead to suggest that H. pylori positive may be related to nausea and vomiting in pregnant women.
The value of a single Widal test was evaluated on 100 clinically suspected typhoid fever cases and 40 agesex matched controls, in the Department of Microbiology, Mymensingh Medical College during the period from July 2006 to June 2007. Blood culture and Widal test with rising titre were performed in all patients. Among 100 clinically suspected of typhoid fever cases, 35 were subsequently confirmed on the basis of positive blood culture for S. typhi and/or significant rising titre of Widal test. The sensitivity, specificity, positive and negative predictive value of a single Widal test was found as 42.85%, 85.00%, 71.42% and 62.96% respectively. Thus, an elevated levels of agglutinating O and H antibodies as measured in a single Widal test might be helpful in making a presumptive diagnosis of typhoid fever if interpreted with care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
