[Prevalence and determinants of low back pain in hospital workers]. / Prevalenza e fattori determinanti delle lombalgie tra i dipendenti dell'ospedale di Terni.

This study evaluated the prevalence and determinants of low back pain (LBP) in Terni hospital workers. Each ward sister completed a questionnaire about potential determinants of LBP associated with physical loads. Moreover, a trained ward sister administered a questionnaire about the characteristics of low back pain to 512 subjects. In the previous year the prevalence of LBP was 58.8%. It was more common in subjects under 45 years of age. >3 LBP episodes annually were more frequent in operating rooms and medical wards. LBP lasted >1 week in 29% of females and in 23% of males. LBP caused change of duties or time off work in 11% of females and in 8% of males.

Short-term effectiveness of an asthma educational program: results of a randomized controlled trial.

Asthma educational programs have been shown to reduce the use of emergency room, frequency of severe asthma attacks and hospitalization. However, its effectiveness in other morbidity parameters and on quality of life has yet to be fully understood. This prospective randomized control trial evaluated the effectiveness of a patient education program in 77 asthmatics according to "Teach Your Patients About Asthma: A Clinicians Guide" (1992). Forty asthmatic patientswere randomly allocated to Group A (usual treatment) and 37 to Group B (usual treatment plus a patient education program). The effectiveness of the educational program was evaluated by comparing morbidity outcomes at baseline and 3 months after initial evaluation. At enrolment, the two groups were not different with regard to age, sex, smoking, asthma severity atopy, FEV1, symptom-free days, use of rescue salbutamol and quality of life. Three months later, subjects in Group B showed a significant improvement in the overall quality of life (p < 0.01) and in the "Symptoms"domain (p < 0.01). None of the other parameters (use of rescue salbutamol, symptom-free days, days absent from work or school, FEV1) showed any significant change. After stratification for asthma severity, only subjects with moderate-to-severe asthma showed a significant improvement inthe overall qualityof life (p < 0.05) and in the "Symptoms" (p < 0.01) and 'Activities" (< 0.05) domains. Moreover, in subjects with moderate-to-severe asthma FEV1 value at the 3rd month of follow-up was higher in Group B than in Group A (p < 0.05). In conclusion, the educational program improved the quality of life in asthratic subjects, mainly in patients with moderate-to-severe asthma.

Reported diagnosis of previous asthma in a sample of the Italian general population.

In this cross-sectional study we describe the prevalence and characteristics of subjects who self-reported a diagnosis of previous asthma in a sample of the Italian general population. We chose a wide age range (3-69 yrs) in order to obtain data over a large spectrum of the population. Interviews were conducted in 1,038 subjects by trained physicians using a modified version of the American Thoracic Society and National Heart & Lung Institute--Division of Lung Disease questionnaire proposed in 1978 (ATS-DLD-78). 791 subjects underwent skin prick tests for 7 common aeroallergens; 422 subjects underwent spirometry and 212 methacholine challenge tests. Cumulative prevalence of asthma was 7.9% (82/1038). Previous asthma (PA) was reported by 29 (35.4%) of the subjects, who said they had been but were no longer asthmatic; 65.5% of these claimed that PA had developed at or before the age of 14 yrs. No significant differences emerged in sex, age, family and personal history of atopy, and size of skin test reaction in subjects with PA compared to those with current asthma (CA). Although the difference was not statistically significant, the latter tended to be lifetime nonsmokers while subjects with PA were more often current smokers. Age at onset of asthma was significantly higher in subjects with CA than in subjects with PA (24.6 +/- 20 yrs vs. 12.0 +/- 15.0 yrs, p = 0.005). Bronchial hyperreactivity was present in 37.5% of subjects with PA, while forced expiratory volume in 1 sec (FEV1) was within normal limits in all. In conclusion, in this sample of the Italian population, PA was reported by about 1/3 of the asthmatic subjects, most of whom were atopic. Lung function was within normal limits in all, but bronchial hyperreactivity persisted in 1/3 subjects.
