Schistosomiasis haematobia : Hidden morbidity bared on the studies on the villagers' perception of disease

本研究试图定性和定量地检查肯尼亚人感染埃及血吸虫引起的排尿，并了解治疗对排尿的效果。此外，我们还研究了向社区提供简单和较便宜的自来水对预防疟疾的影响。排尿功能的定性和定量研究：在血吸虫病流行区和非流行区，采用国际前列腺症状评分法（IPSS）和尿流率测定仪对男、女生进行排尿功能检查。流行区村民IPSS值显著高于对照组。尿流率指标中，T延迟值在病区男生中较高。血吸虫病流行区男性尿量校正Qmax和Qave均降低，提示血吸虫病流行区村民无排尿症状和体征。男孩们在感觉到排尿的冲动后需要更长的时间才开始排尿。男性可能会表现出较弱的排尿功能。治疗对排尿的影响：采用尿流率计和人类学家问卷调查法对男学生进行排尿检查。该研究揭示了排尿的症状。例如，患者在排尿结束时感到疼痛。未料到的是，治疗6个月后排尿的任何症状和体征均未得到改善.自来水对血吸虫病防治的影响：非政府组织提供的社区自来水对血吸虫病防治有一定的效果。但尿虫卵、人水接触、饮用自来水对血吸虫病的预防效果不明显。

The present study was attempted to examine qualitatively and quantitatively the micturition caused by Schistosoma haematobium infection, and to know the efficacy of treatment on micturition in Kenya. In addition, we examined the effect of the simple and less expensive piped water supply to the community on the prevention of schistosomiasis.1. Qualitative and quantitative studies on micturition :In the endemic areas of schistosomiasis and non-endemic area, the school boys and men were examined for micturition by International Prostate symptoms Score (IPSS) and uro-flow meter. Villagers in the endemic areas showed significantly higher IPSS value. Among the indicators of uro-flow meter, high value of T-delay was noticed for school boys in the endemic areas. The men of the endemic areas showed reduced Qmax and Qave corrected by urine volume.These results indicate that villagers in the endemic areas of schistosomiasis suffer from any symptoms and signs of micturition. The boys need the longer time to start urination after they feel an urge of urination. Men were likely to present less powerful urination.2. Effect of treatment on micturition :The school boys were examined for micturition by uro-flow meter and questionnaire made by an anthropologist. The study disclosed the symptoms of micturition. For example, the patients have the pain at the end of urination. Unexpectedly, any symptoms and signs of micturition were not improved 6 months after treatment.3. Effect of piped water supply on the prevention of schistosomiasis :Community piped water provided by NGO was expected to be effective for the prevention of schistosomiasis. However, the observation on eggs in urine, human-water contact at river, and utilization of piped water by villagers did not show any effect on the prevention of schistosomiasis.
