Methods: One hundred and seventy four (174) Respondents were ad- ministered questionnaires on their sociode- mographic characteristics, behavioural practices and knowledge of typhoid fever. Results: Ma- jority of the food handlers drank pure water (32.1%), borehole water (32.6%) and public tap water (31.1%) at the about the same frequecy. More than half (62.2%) washed their hands with water only before eating while 27.7% did not wash their hands always before preparing food. After using toilets, 71.9% washed their hands with soap and water while 28.1% washed their hands with only water. When asked if they had heard about typhoid fever 90% said they had heard, out of which15.6% did not know how it was contracted while the others had partial knowledge. Conclusion: Food handlers play a prominent role in the transmission of typhoid fever and so it is important that the food handlers are well informed about their hygiene status and the causes of typhoid fever trans- mission and ways by which typhoid fever spread is prevented. This will go a long way to help reduce the incidence of typhoid fever in the country.展开更多

This study aimed to compare the efficacy, and safety of levofloxacin and ciprofloxacin for typhoid fever. From 110 patients with confirmed typhoid fever, 54 patients received oral levofloxacin 500 mg once daily with one drop out, while 56 received ciprofloxacin 500 mg twice daily for 7 days with two drop outs. Defervescence of fever was achieved on an average of 3 days after initiating levofloxacin and 5 days after starting ciprofloxacin and one microbiologically non confirmed typhoid fever relapse occurred in the levofloxacin group while two relapses with positive Salmonella microorganism occurred in the ciprofloxacin group. No carrier of Salmonella typhi was found in both groups at day 30. Adverse reactions were more pronounced in the ciprofloxacin group compared to the levofloxacin group. In conclusion, oral levofloxacin 500 mg once daily for one week showed faster fever clearance compared to ciprofloxacin 500 mg twice daily in typhoid fever in Indonesia, and less adverse reactions occurred with levofloxacin compared to ciprofloxacin.

Central nervous system involvement is not rare and reported incidence varies from 5% to 35% [1]. Various well-known neuropsychiatric manifestations include confusional state, encephalopathy, meningism, convulsions and focal neurological deficits. Acute cerebellar ataxia as an isolated neurological complication of enteric fever is very rare and limited to only a few case reports [2]. Here we report a case of enteric fever who presents Acute Cerebellar Ataxia.展开更多

It is endemic in the developing countries including Egypt. Different diagnostic tools can achieve diagnosis and include cultures from the blood, stool, bone marrow, rarely urine for isolation of the organism. Antibody detection by Widal test and relatively recent typhoid are also used. The current study aimed at comparing the most commonly used antibody detection Widal test with the rapid antibody detection typhidot for diagnosis of typhoid fever among Egyptian adults. Patients and Methods: The study included 140 patients who are presented with picture suggestive of typhoid fever. Confirmed cases after the blood culture were included in the final analysis. Widal and typhidot tests were performed in all patients and were compared for sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy. Results: 45 patients out of 140 were diagnosed as typhoid fever by blood culture. Out of them, Widal test was positive in 39 patients with sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 86.7%, 89.5%, 79.5%, 93.4% and 88.5% respectively. Typhidot test was positive in 42 patients with sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 93.3%, 90.6%, 82.3%, 96.6%, and 91.4% respectively (P = 0.00). Conclusions: Typhidot test is reliable, simple highly sensitive and specific test in diagnosing typhoid fever when compared with Widal test.展开更多

The most serious complication is typhoid intestinal perforation(TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical-and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short-to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient's conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.展开更多

Recent studies show that almost all regions of sub-Saharan Africa are tending towards high incidence rates, especially Central and Western Africa. Though clinically indistinguishable from paratyphoid fever, typhoid fever causes more morbidity and mortality than paratyphoid fever, with a greater threat to children. Risk factors include consumption of contaminated water, patronizing food vendors and a history of contact with a case or a chronic carrier, amongst others. Environmental factors such as the rainy season, open sewers, contaminated water bodies and areas of low elevation have been implicated. Diagnosis in Africa is challenging due to resource constraints, as many centres still depend on clinical diagnosis and serodiagnosis using Widal test, in an era where more sensitive and specific tests exist. The polymerase chain reaction is one of the most sensitive diagnostic methods, while culture (particularly bone marrow) is considered to be one of the most specific. Quinolones (ciprofloxacin) and third-generation cephalosporins, amongst others, remain potent in the management of enteric fever, with resistance to quinolones gradually on the rise. Poor diagnostics, poor antibiotic stewardship and lack of drug (antibiotic) regulation are contributors to the problem of antibiotic resistance in Africa. Prevention of typhoid fever through;vaccination, especially in children is still under investigation, with steady progress being documented. Overall, long term prevention strategies for typhoid fever should be based on improved sourcesof drinking water, good sanitation and hygiene, food safety and poverty alleviation.展开更多

文摘Enteric fever remains a tropical disease of public health significance in Africa, due to its high endemicity and transmission rates, more in sub-Saharan Africa with 7.2 million cases of typhoid fever annually and incidence rate of 762 per 100000 person-years when compared with Northern Africa with a reported incidence rate of 557 per 100000 person-years and lower. Recent studies show that almost all regions of sub-Saharan Africa are tending towards high incidence rates, especially Central and Western Africa.
