BACKGROUND There is limited information on field epidemiology of bronchial asthma in Indian adults. OBJECTIVES To estimate prevalence of bronchial asthma in different regions of India and to define risk factors influencing disease prevalence. METHODS A field study was conducted at Chandigarh, Delhi, Kanpur and Bangalore through a two stage stratified(More)
BACKGROUND & OBJECTIVES There is a paucity of data from India on the risk factors for lung cancer. In the present paper results of a case-control study on lung cancer undertaken at Chandigarh, north India, are described. METHODS Two hundred and sixty five (235 men, 30 women) histologically confirmed patients of lung cancer and 525 (435 men, 90 women)(More)
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is a disease that presents with diverse clinicoradiologic manifestations. High-attenuation mucus (HAM) is a characteristic radiologic finding seen in patients with ABPA; however, the clinical significance of the entity remains unknown. AIMS AND OBJECTIVES To describe the outcome of patients with(More)
BACKGROUND The prevalence of Aspergillus hypersensitivity (AH) and allergic bronchopulmonary aspergillosis (ABPA) in bronchial asthma is reported differently in various studies. OBJECTIVE To determine the prevalence of AH and ABPA in asthma using a systematic review. METHODS We searched the MEDLINE and EMBASE databases for studies published from 1965 to(More)
Cyclin D1 is involved in normal regulation of the cell cycle and plays an important role in the transition from G1 to S phase of the cell cycle. The CCND1 gene has a G-->A polymorphism in exon 4 that increases the frequency of alternate splicing. We analyzed the potential role of CCND1 gene polymorphisms in lung cancer patients (n = 151) and in a matched(More)
The aim of this study is to assess the relationship between exposure to environmental tobacco smoke (ETS) and lung cancer in non-smokers, a case-control study among lifetime non-smokers was conducted in Chandigarh, India. Cases consisted of 58 non-smoking histologically confirmed lung cancer patients; two controls for each case were selected, one among(More)
SETTING Field sites in 12 districts in different parts of India. OBJECTIVE To determine the nationwide population prevalence of and risk factors for asthma and chronic bronchitis (CB) in adults. DESIGN A standardised validated questionnaire based on the International Union Against Tuberculosis and Lung Disease's 1984 questionnaire was used to assess(More)
INTRODUCTION Population prevalence of chronic obstructive pulmonary disease (COPD) and its relationship with tobacco smoking, environmental tobacco smoke (ETS) exposure and other variables were studied in adult subjects of 35 years and above at four different centres in India. Question-items for the diagnosis of COPD were included in the questionnaire used(More)
Thyroid function tests (serum levels of thyroxine-T4, triiodothyronine-T3 and thyroid stimulating hormone-TSH) were performed in fifty-eight men (mean age: 31.7±10.6 years; mean duration of lead exposure: 156.9±122.7 months). These subjects were exposed to lead either as petrol pump workers or automobile mechanics. The mean whole blood lead (Pb-B) levels(More)
The interpretation and interpretability of epidemiologic studies of environmental tobacco smoke (ETS) depend largely on the validity of self-reported exposure. To investigate to what extent questionnaires can indicate exposure levels to ETS, an international study was conducted in 13 centers located in 10 countries, and 1,369 nonsmoking women were(More)
