BACKGROUND; A case-controlled study was undertaken to find out the possible relationship of biomass fuel and pulmonary tuberculosis. METHODS: Ninety-five non-smoking females with sputum positive tuberculosis (TB) and 109 healthy controls were interviewed using a questionnaire to obtain detailed information on type of fuel used in homes, duration of cooking, passive smoking, location of kitchen, socio-economic status, adequacy of ventilation, number of people per room and respiratory symptoms occurring during cooking. Odds ratio (OR) was ascertained by logistic regression analysis. RESULTS: The cases were from a low socio-economic status and the kitchens used by them were inadequately ventilated. Controls had less smoke accumulation in the rooms while cooking and cases had associated respiratory symptoms more often. Logistic regression analysis revealed that TB was significantly influenced by the location of the kitchen (OR 0.201, 95% confidence interval [CI] 0.08-0.51) and the presence of respiratory symptoms while cooking (OR 10.70, 95% CI 2.90-39.56). The odds of having TB did not differ significantly among various fuel types either on univariate (OR 0.99, 95% CI 0.45- 2.22) or multivariate analysis (OR 0.60, 95% CI 0.22-1.63). CONCLUSIONS: No association was found between type of fuel used and TB. However, low socio-economic status, smoky rooms, location of the kitchen, ventilation and associated respiratory symptoms during cooking are likely to be important contributors.

To study the seasonality of tuberculosis (TB) in a tertiary care tuberculosis and respiratory hospital in Delhi. Data from a tertiary care respiratory hospital in south Delhi over a six years period from April 2002 to March 2008 were analysed. Symptomatics: A total of 192,863 patients were registered newly in the hospital during this period. Maximum number of symptomatic patients reported to the out-patient department during April-June and the minimum during October-December. An increase of about 25% in symptomatics was observed (p < 0.05) in the period from April to June in comparison to October to December. The amplitude of seasonal variation was estimated as 11% of the annual mean symptomatics. Tuberculosis cases: The maximum sputum-positive TB cases were diagnosed during the period from April to June and the number was least during October to December. There was an increase of about 34% in sputum-positive cases (p < 0.001) during the period from April to June against October to December. The amplitude of seasonal variation was estimated as 14.4% of the annual mean smear-positives per quarter. The extra-pulmonary TB (EPTB) cases were the maximum during April-June. Chest symptomatics of all types of TB cases were the lowest in January. A seasonal pattern of TB was observed for pulmonary TB and EPTB cases. This information would be useful for administration and managers to take extra care to arrange and provide extra facilities during the peak seasons.

To review the surgical management of congenital malformations of lung parenchyma in a thoracic surgery unit over a period of 15 years. We carried out a retrospective analysis of records of all patients who had surgery for congenital malformations of lung parenchyma between 1995 and 2010. Forty-five patients underwent surgery for congenital lung lesions out of 3735 thoracotomies performed during the study period. The lesions included 29 lung sequestrations, 12 bronchogenic cysts, 3 congenital lobar emphysema and one congenital cystic adenomatoid malformation. Only 26 (26%) cases were diagnosed preoperatively. Twenty-eight (62.2%) patients underwent lobectomy, 5 (11.1%) patients had pneumonectomy, and 10 (22.2%) patients had removal of cyst while 2 (0.45%) patients had lung resection with repair of the oesophageal connection. No mortality was recorded. One patient had post-operative complication of oesophageal fistula which was successfully managed conservatively. The follow-up was between 8 months to 14 years. All patients were asymptomatic and had no physical limitations during the follow-up. Surgery is curative and produces good long-term result in patients with congenital malformations of lung parenchyma. It should be offered to patients as a therapeutic option where indicated and feasible.

Spontaneous acquired diaphragmatic hernia without any apparent history of trauma is a very rare condition and is very difficult to diagnose. We present a case of a 21-year-old male who presented with abdominal pain for one month and four episodes of vomiting for one day. Clinical suspicion, chest radiography with nasogastric tube in situ and computed tomography (CT) confirmed the diagnosis. The diaphragmatic defect was repaired surgically. The patient had an uneventful post-operative recovery.

Earlier studies indicate that genotyping of Mycobaterium leprae based on single-nucleotide polymorphisms (SNPs) is useful for analysis of the global spread of leprosy. In the present study, we investigated the diversity of M. leprae at eight SNP loci using 180 clinical isolates obtained from patients with leprosy residing mainly in Delhi and Purulia (West Bengal) regions. It was observed that the frequency of SNP type 1 and subtype D was most predominant in the Indian population. Further, the SNP type 2 subtype E was noted only from East Delhi region and SNP type 2 subtype G was noted only from the nearby areas of Hoogly district of West Bengal. These results indicate the occurrence of focal transmission of M. leprae infection and demonstrate that analysis by SNP typing has great potential to help researchers in understanding the transmission of M. leprae infection in the community. © 2013 European Society of Clinical Microbiology and Infectious Diseases.
