Treatment seeking behaviour and costs due to acute and chronic forms of lymphatic filariasis in urban areas in south India.

Previous estimates on the economic burden of lymphatic filariasis (LF) in India and elsewhere were primarily based on studies in rural areas. We investigated the treatment costs due to acute and chronic forms of LF in urban areas, where nearly one-third of the affected people live. Almost 98% of the patients with acute episodes of adenolymphangitis (ADL) underwent treatment and 49% of chronic patients also received treatment. The average treatment cost per ADL episode (n = 108) was Rs 22.21 +/- 53.84 (US dollars 0.46 +/- 1.12). The overall (n = 200) treatment costs incurred by a chronic patient per visit were Rs 16.71 +/- 62.36 (US dollars 0.35 +/- 1.30); for those who paid (n = 98) they were Rs 34.10 +/- 85.90 (US dollars$ 0.71 +/- 1.79). These costs are considerably higher than in rural areas. Government health centres and private practitioners were important sources of treatment. Treatments received from private practitioners were considerably more expensive than those from government health facilities. The cost of medicine accounted for 44% and 50% of the total expenditure on treatment for acute and chronic disease patients, respectively. The medical personnel from these treatment sources need to be trained on the new morbidity management methods, which are likely to be more effective than the current methods of treatment.

Community perception of Malayan filariasis in the rural areas of Cherthala Taluk of Kerala State, south India.

Lymphatic filariasis, one of the major public health problems can be controlled with the active participation of the community. The human factors involved in the disease transmission are important. The knowledge on the community perception and practice is essential to develop community oriented control programmes. A descriptive study was conducted in the filariasis endemic area of Cherthala, Kerala State, India, to identify the level of people's perception on Malayan filariasis. Two methods namely, interviews and uncontrolled observation were used in the study. A total of 450 respondents (150 microfilaria carriers, 150 chronic patients and 150 normals) were interviewed. The study results showed that majority of the respondents (86.7%) were aware that the disease was caused by a parasite and 93.6% had awareness on transmission of the disease through mosquito bite. The knowledge on the preventive measures against filariasis was also high (78.2%) among the sampled respondents. The strategy for community mobilization in filariasis control programme is discussed in view of high awareness.

Action of some insect growth regulators on mosquito vectors: Part I--Citronellol based diethers.

New series of compounds starting from common terpenoids (Geraniol, citronellol) have been examined for biological activity on mosquito larvae. Many of these exhibited development disruption on eggs as well larvae. Some also affected adult oviposition behaviour. Developmental disturbances were classified as JH type by inducing typical metamorphosis inhibition in Dysdercus koenigii in the standard Hemipteran JH bioassay. Where indicated simulated field trials were also undertaken. This report describes results of bioevaluation of the citronellol based compounds. The results indicate that these show multifarious activity against mosquitoes but at relatively high doses, suggesting that exploration of further structural variety is needed before truly promising analogues can be obtained.

Chorioangiomas.

Six cases of chorioangioma of the placenta and a review of relevant leterature are presented. The incidence of chorioangiomas is higher than generally realized because many small chorioangiomas are missed in routine examination of placentas. A case of chorioangioma with foci resembling hemangiopericytoma is presented. Cases of large chorioangiomas seem to occur when the placenta is large. Hydramnios is commonly found with large chiorangiomas, and both of these conditions may be conducive to premature births. There is an increased incidence of toxemia in pregnant patients with chorioangiomas, and the condition is unrelated to the size of the tumor. Diligent examination of infants associated with chorioangioma of the placenta is suggested, as these infants may have unsuspected congenital anomalies.
