Immunization evaluation surveys have shown a wide variation across regions, states and different strata of the society.

The authors conducted a cross-sectional study among residents of Delhi to determine the role of ambient air pollution in chronic respiratory morbidity in Delhi. The authors selected a random, stratified sample (N = 4,171) of permanent residents who were 18+ y of age and who lived near 1 of the 9 permanent air quality monitoring stations in the city. Air-quality data for the past 10 y were obtained; data were based on the differences in total suspended particulates, and the study areas were categorized into lower- and higher-pollution zones. A standardized questionnaire was administered, clinical examination was carried out, and spirometry followed. The authors assessed chronic respiratory morbidity by (a) prevalence of chronic respiratory symptoms (i.e., chronic cough, phlegm, breathlessness, and wheezing) and airway diseases (i.e., chronic obstructive pulmonary disease/chronic bronchitis and bronchial asthma); and (b) lung function results in asymptomatic nonsmoking subjects in the two pollution zones. A multiple logistic regression identified the determinants of chronic symptoms. Smoking, male sex, increasing age, and lower socioeconomic status were strong independent risk factors for occurrence of chronic respiratory symptoms. In the comparison of nonsmoking residents of lower- and higher-pollution zones--stratified according to socioeconomic levels and sex--chronic cough, chronic phlegm, and dyspnea (but not wheezing) were significantly more common in the higher-pollution zone in only some of the strata. Furthermore, prevalence rates of bronchial asthma, chronic obstructive pulmonary disease, and chronic bronchitis among residents in the two pollution zones were not significantly different. Nonetheless, lung function of asymptomatic nonsmokers was consistently and significantly better among both male and female residents of the lower-pollution zone.

Maternal mortality is one of the important indicators used for the measurement of maternal health. Although maternal mortality ratio remains high, maternal deaths in absolute numbers are rare in a community. To overcome this challenge, maternal near miss has been suggested as a compliment to maternal death. It is defined as pregnant or recently delivered woman who survived a complication during pregnancy, childbirth or 42 days after termination of pregnancy. So far various nomenclature and criteria have been used to identify maternal near-miss cases and there is lack of uniform criteria for identification of near miss. The World Health Organization recently published criteria based on markers of management and organ dysfunction, which would enable systematic data collection on near miss and development of summary estimates. The prevalence of near miss is higher in developing countries and causes are similar to those of maternal mortality namely hemorrhage, hypertensive disorders, sepsis and obstructed labor. Reviewing near miss cases provide significant information about the three delays in health seeking so that appropriate action is taken. It is useful in identifying health system failures and assessment of quality of maternal health-care. Certain maternal near miss indicators have been suggested to evaluate the quality of care. The near miss approach will be an important tool in evaluation and assessment of the newer strategies for improving maternal health.

In view of the substantial burden on family caregivers coupled with lack of adequate number of cancer hospitals, there is a public-health imperative to recognize this important group. All levels of health-staff in cancer hospitals in developing countries should be sensitized to the various burdens faced by family caregivers.
