Aim To examine tuberculosis incidence rates among the elderly in Central Serbia in 1992-2006 period, which was characterized by socioeconomic crisis and migration of population.Methods We analyzed all reported active tuberculosis cases in a 15-year period, especially among patients aged ≥65, according to the Annual Reports of the Institute of Lung Diseases and Tuberculosis in Belgrade and Central Tuberculosis Register. Population estimates with extrapolations were based on 1991 and 2002 census data.Results Total tuberculosis incidence rates showed a slight but nonsignificant decreasing trend (P = 0.535), and no significant increase was found in patients aged ≥65 years (P = 0.064), with an average agespecific incidence rate for the elderly of 64.0 (95% confidence interval, 60.7-67.4). The increase was significant in patients aged ≥70 years (y = 49.3549 + 2.1186x; P = 0.001), both in men (y = 62.8666 + 2.3977x; P = 0.005) and even more prominently in women (y = 39.8240 + 1.9150x; P < 0.001). The proportion of tuberculosis cases in the elderly peaked in 2005, with 35% of all tuberculosis cases.Conclusion High incidence rates and increasing time trend of tuberculosis in the elderly in Central Serbia is a serious problem, especially among those aged 70 years and over, who might present a target group for active case-finding of the disease.
Laryngeal cancer is the most common head and neck cancer. There might be many risk factors for laryngeal cancer. Smoking, especially cigarette smoking and alcohol are indisputable risk factors. The authors of this paper assessed the presumed risk factors in order to identify possible aetiological agents of the disease. A hospital-based case-control study was conducted. The study group consisted of 108 histologically verified laryngeal cancer patients and 108 hospital controls matched by sex, age (±3 years) and place of residence. Laryngeal cancer patients and controls were interviewed during their hospital stay using a structured questionnaire. According to multiple logistic regression analysis six variables were independently related to laryngeal cancer: hard liquor consumption (Odd Ratio /OR/=2.93, Confidence Interval /CI/ 95 % = 1.17 to 7.31), consumption more than 2 alcoholic drinks per day (OR=4.96, CI 95 % = 2.04 to12.04), cigarette smoking for more than 40 years (OR=4.32, CI 95 % = 1.69 to 11.06), smoking more than 30 cigarettes per day (OR=4.24, CI 95 % = 1.75 to 10.27), coffee consumption more than 5 cups per day (OR=4.52, CI 95 % = 1.01 to 20.12) and carbonated beverage consumption (OR=0.38, CI 95 %= 0.16 to 0.92). The great majority of laryngeal cancers could be prevented by eliminating tobacco smoking and alcohol consumption.
The study comprised all 113 clinically and histologically confirmed cases of Hodgkin's disease aged 15-39 years who were treated at the Department of Hematology of the Faculty of Medicine in Belgrade from January, 1 to June, 30, 1987. For each patient, two individually matched controls were selected. Neighbourhood controls were the first neighbours of the same sex, age, and residence history. Hospital controls consisted of accidentally injured individuals, and they were matched in terms of sex, age, place of residence, and educational level. Comparison of cases and controls revealed that removal of the lymphoid tissue (either tonsils or appendix) did not affect the risk of developing Hodgkin's disease in any way. An association found by some previous studies has been explained by the confounding effect of socioeconomic status.
The aim of this study was to investigate factors related to osteoporosis in postmenopausal women in Belgrade. A case-control study was conducted during 2006-2007. The study group consisted of 100 newly diagnosed osteoporosis patients and 100 age-matched controls (± 2 years). The inclusion criteria for the case group were newly diagnosed osteoporosis confirmed by dual-energy X-ray absorptiometry of the lumbar spine and being menopausal (at least 2 years of amenorrhea). The inclusion criteria for the control group were postmenopausal women with confirmed normal bone mineral density of the lumbar spine by dual-energy X-ray absorptiometry. All study participants were interviewed using a structured questionnaire. Univariate and multivariate logistic regression analyses were used. The following factors were significantly independently related to osteoporosis: low body weight (P < 0.001), thin constitution in childhood (P = 0.002), history of previous fracture (P = 0.033), menopause at age <47 years (P < 0.001), family history of fracture (P = 0.005), and less frequent consumption of cheese (P = 0.027) and fish (P = 0.020). The majority of factors identified may be modifiable and could be influenced to prevent postmenopausal osteoporosis.
The objective of this study was to establish the tuberculosis incidence and mortality in children in Serbia in the period 1992-2002. There were 280 reported cases. The average annual incidence rate was 1.79/100,000 (95% confidence interval, 0.92-3.13). The rate was higher in girls than in boys. Eleven children died. The average annual mortality rate was 0.10/100,000 (95% confidence interval, 0.01-0.56). The mortality rates for both boys and girls were higher in the age group 0-4 years than in older age group.
