Physico-chemical characteristics of Anopheles breeding sites: Impact on fecundity and progeny development

Mosquitoes exploit almost all types of aquatic habitats for breeding. Prevailing physicochemical parameters in these habitats are important factors for survival and development of mosquito. Here, six water samples from Atlantic Ocean, River, well, distilled (control), rain and borehole water were used to culture Anopheline eggs collected from pure bred of Kisimu species. The development of eggs to 1st, 2nd, 3rd and 4th instars larval, pupal and adult stages were observed from day 1 to 6 using six replicates of each water sample. The number of eggs laid (fecundity) by the emerged adults were estimated using counting microscope. Level of development in emerged adults was determined using the wing size. The analysis of the physicochemical parameters of the water samples was carried out in the Nigerian Institute of Marine and Oceanography. The physicochemical characteristics were compared with the rates of development and fecundity of the Anopheline species. Statistical analysis using ANOVA indicates no significant difference (P > 0.05) in the hatchability of the eggs. However, the rates of larval development to pupal stage and subsequent adult emergence showed a level of significant difference (P 0.05). This study provides information on mosquito ecology in relation to breeding habitat which may have bearing on vector population and distribution as well as malaria transmission in a particular area

Client perception of radiotherapy services at the Lagos University Teaching Hospital, Lagos, Nigeria

Assessment of quality from the patient's perspective could be a method of aiding improvement of services to achieve total quality management. This study set out to determine the level of knowledge of radiotherapy among patients and assess their attitude to the radiotherapy services provided at the Oncology clinic of the Department of Radiotherapy, Lagos University Teaching Hospital Nigeria. Data collection was by self-administered questionnaires using a systematic random sampling technique of every second patient attending the clinic over a period of six months. Both old and new patients were included in the study. A total of 104 patients were interviewed. More than two-thirds of the respondents (70.2%) were females. Most (86.3%) of the female respondents were aged 30- 69yrs. A quarter (25.8%) of the male respondents were under 30 years. The majority of both males (62%) and females (58.9%) had at least senior secondary education. Majority of the respondents (males, 54.8% and females, 61.6%) were reassured in terms of the treatment modalities being received. About two-thirds (64.5%) of the males and three -quarters (74.0%) of the females felt they had improved chances of survival. Majority of the males (51.6%) and females (57.5%) felt that radiotherapy had its worth in the management of their conditions. Most (94.5%) of the clients who perceived radiotherapy to be of adequate worth felt there was an improvement in their condition. The study recommended the need for improved communication in doctor – patient relationships in chronic diseases such as cancer.
