ABSTRACT
BACKGROUND: Schistosomiasis and soil transmitted infection is a major health problem of children from rural areas of developing countries including Yemen. In an attempt to reduce this burden, the Ministry of Public Health and Population in Yemen established in 2002 a programme for Schistosomal, soil transmitted infection control that aimed to reduce morbidity and prevalence rates of Schistosomiasis, and Soil transmitted helminthes to less than 5% by 2015. The study was conducted to assess the current prevalence and intensity of schistosomal infection among schoolchildren in rural areas of the Taiz governorate after 6 years of running National Control Programme. METHODS: Grade 3 schoolchildren from Shara'b Al-Raona district of Taiz Governorate were examined for infections with Schistosoma mansoni using Modified Kato-Katz method and S. haematobium applying filtration method in 1998/1999, comparing the prevalence and intensity of infection with base line study, which was done 6 years ago. RESULTS: The S. mansoni prevalence in the study population was 31%, while the prevalence of S. haematobium was 18.6%. This result considerably is similar to the prevalence of base line study. The intensity of mild, moderate and severe infection for S. mansoni reached to 15.9%, 60.6% & 23.5% respectively. The severity of S. haematobium infection was 68.4%. It was exceptionally found that the prevalence of S. haematobium is increased. CONCLUSION: The high prevalence of schistosomiasis and low effectiveness of control programme against schistosomal infection in the study area demands consideration of alternative treatment approaches.
ABSTRACT
We carried out a retrospective study of all patients admitted to Al-Thawra Teaching Hospital in Sana'a with hepatocellular carcinoma to study the disease profile in Yemeni patients and identify possible risk factors. During the 8-year study period, January 2001-December 2008, 251 patients were admitted with confirmed hepatocellular carcinoma. From hospital records we collected data on demographic characteristics, clinical manifestations, histological characters, viral markers, treatment and outcome. Around 75% of the patients were males. Age range was 26-75 years, mean 53.5 (SD 13.9) years. Most patients were farmers (73.7%) and had a history of chemical contact. Chronic hepatitis B virus infection (48.2%) and hepatitis C virus infection (38.2%) were the most frequently identified risk factors. Qat chewing and smoking were not statistically significant risk factors. Right lobe involvement was seen in 109 (43.4%) patients and 154 (61.4%) presented with multiple lesions. We found 187 (74.0%) patients had cirrhotic liver associated with hepatocellular carcinoma. Overall mortality rate within 6 months of admission to hospital was 24.3%.

During the 8-year study period, January 2001-December 2008, 251 patients were admitted with confirmed hepatocellular carcinoma. From hospital records we collected data on demographic characteristics, clinical manifestations, histological characters, viral markers, treatment and outcome. Around 75% of the patients were males. Age range was 26-75 years, mean 53.5 [SD 13.9] years. Most patients were farmers [73.7%] and had a history of chemical contact. Chronic hepatitis B virus infection [48.2 %] and hepatitis C virus infection [38.2%] were the most frequently identified risk factors. Qat chewing and smoking were not statistically significant risk factors. Right lobe involvement was seen in 109 [43.4%] patients and 154 [61.4%] presented with multiple lesions. We found 187 [74.0%] patients had cirrhotic liver associated with hepatocellular carcinoma. Overall mortality rate within 6 months of admission to hospital was 24.3%
