Left coronary artery arising from the non-coronary sinus: a rare congenital coronary anomaly.

Anomalous origin of the left coronary artery is a cause of sudden death in adolescents and young adults. Most commonly, it originates from the right coronary sinus or the pulmonary artery. Origin of the left main coronary artery from the non-coronary sinus of Valsalva is extremely rare. We report a case of a child with anomalous origin of the left main coronary artery from the non-coronary sinus diagnosed during the evaluation of a ventricular arrhythmia.

Bancroftian filariasis in Namrup tea estate, district Dibrugarh, Assam.

Filariasis survey in a randomly selected tea estate of district Dibrugrah revealed 6.7% infection of Wuchereria bancrofti in labour population with microfilaria (mf) rate of 7.6% in males and 5.9% in females. The mf rate increased progressively with the age which however, dropped in 31-40 age group of males and in 41-50 age group of females. Chronic filariasis diseases rate was 2.7%. The involvement of genitals in manifesting chronic filariasis was significantly higher than of the lower extremities. Infection and infectivity rates in the vector mosquito, Culex quinquefasciatus were 6.1% and 4.6% respectively with mean L3 load per infective mosquito of 8.5. Drains, land, peridomestic ditches were chief breeding habitats of Cules quinquefasciatus in the tea estate.

Risk factors of malaria in the fringes of an evergreen monsoon forest of Arunachal Pradesh.

BACKGROUND: The forested hilly and foothill regions of north-east India are highly endemic for malaria and have a distinct epidemiological pattern. Nearly half the reported cases of malaria are from these areas. A knowledge of the risk factors in this eco-geographic entity may be helpful in formulating a specific control strategy. Hence, we conducted a community-based epidemiological study in a hilly, forested terrain of Arunachal Pradesh and examined different socio-demographic factors to identify those predisposing to the occurrence of malaria, especially Plasmodium falciparum infection, in such areas. METHODS: Four epidemiological surveys were carried out during 1997 in 7 villages located at the fringes of a forest (total population: 1177) under Nompong Primary Health Centre of Changlang district, Arunachal Pradesh. Blood slides were collected randomly from the inhabitants, irrespective of their fever status, ensuring at least 50% coverage. One hundred and thirty-four microscopically confirmed Plasmodium falciparum cases were identified and 536 controls were randomly selected from the list of uninfected inhabitants. Relevant socio-demographic information was obtained from both cases and controls. The data were analysed by simple and multiple logistic regression using the unconditional maximum likelihood method. RESULTS: Factors which were found to be strongly associated with Plasmodium falciparum malaria on univariate analysis were age, ethnicity, village of residence and accessibility to the nearest health care facility. However, in multiple regression analysis, after controlling for the effects of confounding variables, the only risk factor identified was accessibility to the nearest health care facility (adjusted odds ratio: 4.5; 95% CI: 1.8-11.3; p < 0.0001 for those at a distance of 2-8 km and adjusted odds ratio: 11.1; 95% CI: 4.1-30.0; p < 0.0001 for those > 8 km away). CONCLUSION: Distance, particularly non-motorable distance, from the place of residence to the nearest health care facility was a major risk factor for malaria in this hilly forested terrain. This indicates the need for special efforts to detect cases early and institute treatment promptly in such areas of the north-eastern region, so as to reduce the morbidity and mortality of malaria.

Adenosquamous carcinoma of colon.

Primary adenosquamous carcinoma of the colon is an aggressive entity. We report a 41-year-old man with a combination of adenocarcinoma and squamous cell carcinoma of the cecum, treated by right hemicolectomy and ileo-transverse anastomosis. Postoperatively he received adjuvant chemotherapy. However, the tumor recurred at the original site within two months and thereafter the patient was lost to follow up.

Mosquito fauna and malaria vectors in Jairampur, district Changlang, Arunachal Pradesh.

In an entomological study, covering three biotopes like village, panikheti (wet rice cultivated land) and urban agglomeration, a total of 35 species of mosquitoes in eight genera were recorded in Jairampur area of Arunachal Pradesh. Two mosquito species--Orthopodomyia anopheloides and Tripteroides indicus were recorded for the first time in Arunachal Pradesh. Anopheles dirus and An. minimus, the two well-known malaria vectors were encountered in the study along with several potential vector species like An. annularis, An. culicifacies, An. maculatus group and An. philippinensis/nivipes. The diversity of mosquito species as well as the man-vector contact was maximum in the panikheti and minimum in the village biotope.
