Classic Kaposi's sarcoma in Italy, 1985-1998.

To evaluate incidence rates (IRs) of classic Kaposi's sarcoma (CKS) in Italy after the spread of AIDS, we distinguished CKS from AIDS-related KS (AKS) using an 'ad hoc' record linkage procedure between 15 Cancer Registries (CRs) (21% of the Italian population) and the national AIDS Registry. Between 1985 and 1998, 874 cases of CKS and 634 cases of AKS were diagnosed in the study areas. CKS accounted for 16 and 27% of KS cases below 55 years of age in men and women, respectively, but for 91 and 100% of those above age 55. The IRs for CKS were 1.0/ in men and 0.4/100,000 in women, but they varied between 0.3 in Umbria and 4.7 in Sassari in men, and between 0.1 in Parma and 1.7 in Sassari in women. IRs of CKS in both genders were stable between 1985-1987 and 1993-1998. In Northern and Central CRs the IR (adjusted for age and gender) for CKS was 0.5 in individuals born in the same area, but 1.6 in individuals born in Southern Italy or in the Islands (rate ratio = 3.2) suggesting that KS-associated herpesvirus, the cause of KS, is acquired early in life.

Mould/dampness exposure at home is associated with respiratory disorders in Italian children and adolescents: the SIDRIA-2 Study.

AIMS: To report on the relation between home mould and/or dampness exposure and respiratory disorders in a large sample of children and adolescents in Italy, accounting for age at time of exposure. METHODS: 20,016 children (mean age 7 years) and 13,266 adolescents (mean age 13 years) completed questionnaires on indoor exposures and respiratory symptoms/diseases. Statistical analyses were adjusted for sex, age, questionnaire's compiler, area of residence, season of interview, parental educational status, family history of asthma, rhinitis, eczema, chronic obstructive pulmonary disease, presence of gas water heaters, passive smoking, pets, and active smoking (only for adolescents). Population attributable risk % (PAR) was also computed. RESULTS: Asthma was more strongly related to only early than to only current exposure, both in children (OR 1.80, 95% CI 1.41 to 2.30) and adolescents (OR 1.89, 95% CI 1.38 to 2.59). The same result was found for rhino-conjunctivitis (OR 1.46, 95% CI 1.17 to 1.82), in children, and for wheeze among adolescents (OR 1.56, 95% CI 1.15 to 2.11). In children, wheeze (OR 1.98, 95% CI 1.47 to 2.66) and eczema (OR 1.44, 95% CI 1.09 to 1.91) were more strongly related to mould/dampness when exposed both early and currently; the same occurred in adolescents for rhino-conjunctivitis (1.78, 95% CI 1.30 to 2.45). Although persistent cough/phlegm was significantly related to mould/dampness exposure in children, regardless of exposure timing, no significant association between mould/dampness exposure and eczema or cough/phlegm was found among adolescents. PAR estimates were higher for only early than only current exposures. Avoiding early only exposure would abate wheeze by 6%, asthma or cough/phlegm by 7%, rhino-conjunctivitis in children by 4%, and in adolescents, asthma by 6%, and wheeze by 4%. CONCLUSIONS: Respiratory disorders such as wheeze and asthma can often be explained by exposure to home mould/dampness, especially early in life. The association seems more evident in children than in adolescents. These findings may suggest the need for environmental prevention strategies.

The impact of parental smoking on asthma and wheezing. SIDRIA Collaborative Group. Studi Italiani sui Disturbi Respiratori nell'Infanzia e l'Ambiente.

To evaluate the impact of parental smoking on childhood asthma and wheezing, we studied two random samples of subjects ages 6-7 and 13-14 years in ten areas of northern and central Italy. Standardized questionnaires were completed by parents of 18,737 children and 21,068 adolescents (response rates, 92.8% and 96.3%, respectively) about their smoking habits and the respiratory health of their children. Adolescents were asked about their respiratory health and personal smoking. We compared two groups of cases with healthy subjects: (1) "current asthma" (children, 5.2%; adolescents, 6.2%) and (2) "current wheezing" not labeled as asthma (children = 4.5%, adolescents = 8.5%). Exposure to smoke of at least one parent increased the relative risk of current asthma among children [odds ratio (OR) = 1.34; 95% confidence interval (CI) = 1.11-1.62] and of current wheezing among adolescents (OR = 1.24; 95% CI = 1.07-1.44). Maternal smoking had a stronger effect than paternal smoking. Maternal smoking during pregnancy was associated with current asthma (OR = 1.62; 95% CI = 1.34-1.96) and current wheezing in children (OR = 1.31; 95% CI = 1.06-1.62); the effects were lower among adolescents. Among subjects with a negative history of parental asthma, maternal smoking was associated with current wheezing in both age groups, whereas among those with a positive history of parental asthma it was associated with current asthma in children, but not in adolescents. We estimated that 15% (95% CI = 12-19) of the current asthma cases among children and 11% (95% CI = 8.3-14) of the current wheezing cases among adolescents are attributable to parental smoking in Italy.

Road traffic and adverse respiratory effects in children. SIDRIA Collaborative Group.

OBJECTIVES: To investigate the relation between traffic indicators in the area of residence and the occurrence of chronic respiratory disorders in children. METHODS: A population based survey was conducted in 10 areas of northern and central Italy (autumn 1994 to winter 1995) in two age groups (6-7 and 13-14 years). Information on several respiratory disorders and on traffic near residences was collected with a questionnaire given to children and to their parents. The sample analysed included 39,275 subjects (response rate 94.4%). Outcomes were: (a) early (first 2 years of life) respiratory diseases, and (b) current respiratory disorders (asthma, wheeze, cough, or phlegm in the past year). Odds ratios (ORs) and 95% confidence intervals (95% CIs), adjusted for several potential confounders, were estimated from logistic regression models. Main results were stratified by level of urbanisation (metropolitan areas, other centres). RESULTS: In the metropolitan areas, high frequency of lorry traffic in the street of residence was associated with significantly increased risks for many adverse respiratory outcomes. Among early respiratory diseases, the strongest associations were found for recurrent bronchitis (OR 1.69, 95% CI 1.24 to 2.30), bronchiolitis (1.74, 1.09 to 2.77) and pneumonia (1.84, 1.27 to 2.65), although no association was detected for episodes of wheezing bronchitis. All the current respiratory disorders were positively and consistently associated with frequency of lorry traffic, particularly the most severe bronchitic and wheezing symptoms: persistent phelgm for > 2 months (1.68; 1.14 to 2.48), and severe wheeze limiting speech (1.86; 1.26 to 2.73). No or weaker associations with heavy vehicular traffic were detected in urban and rural areas and no increased risks were found in the whole sample with the reported traffic density in the zone of residence. After extensive evaluations, the potential of reporting bias seems unlikely. CONCLUSION: Exposure to exhausts from heavy vehicular traffic may have several adverse effects on respiratory health of children living in metropolitan areas, increasing the occurrence of lower respiratory tract infections early in life and of wheezing and bronchitic symptoms at school age.

[Diagnosis and prognosis of malignant mesothelioma. A description of 8 clinical cases].

A retrospective study of patients at the Trento S. Chiara Hospital in the period 1982-86 showed up 8 cases of malignant mesothelioma (7 pleural and 1 peritoneal). The histology was re-examined for each case and clinical records was also looked at so as to identify onset symptomatology, diagnostic procedures and treatment. A standard questionnaire given to patients or close relations revealed previous exposure to asbestos in 2 of 3 males and in none of the 5 females. There was also a significant delay in formulation of correct diagnosis, attributable on the hand to the nonspecificity of the symptomatology of onset and on the other to the inadequacy of currently available clinical and radiological procedures. Only histology with the aid of immunocytochemical procedures was able to pinpoint correct diagnosis, in life. The ineffectiveness of conventional therapies and the poor overall prognosis for these patients is confirmed.

Skeletal scintigraphy and physical examination in the staging of early breast cancer.

The significance of skeletal scintigraphy in staging of early breast cancer is still controversial. The results of bone scanning with 99Tcm diphosphonate and clinical examination in 204 patients with stage I-II breast cancer are reported. Bone scans were positive in 28 cases. However, only one was true positive as confirmed by x-ray examination and/or biopsy, with a detection rate of 0.5%. Physical examination had a detection rate similar to bone scan, but with superior specificity. In our experience bone scan cannot be recommended as a routine staging test in early breast cancer.

Neoadjuvant chemotherapy with vincristine, bleomycin and methotrexate combined with radiotherapy in advanced head and neck squamous cell carcinoma.

From September 1980 to August 1981, 25 patients with advanced head and neck squamous cell carcinoma were treated at the Centro Oncologico, Trento, by a chemo-radiotherapeutic combination. The treatment protocol consisted of 4-6 courses of VBM (vincristine, bleomycin and methotrexate) followed by conventional radiotherapy (65 Gy). Only to VBM responders (15 patients) were administered 10 cycles of vincristine-methotrexate. At the end of induction chemotherapy an overall response of 60% (12% complete, 48% partial) was obtained. At the end of radiotherapy the responses were 52.5% complete and 35.5% partial, for an overall response of 88%. The overall survival at 60 months was 8%. This combined approach, in spite of the satisfactory immediate local response rate, does not offer advantages for survival in comparison to conventional treatment modalities.

Differences in cancer mortality trends between four neighboring north-eastern areas and Italy, 1970-1990.

AIMS AND BACKGROUND: The present report combines descriptive statistics (partly never published) on four neighboring areas of north-eastern (NE) Italy [Friuli-Venezia Giulia (1970-89) and Veneto (1970-87) regions and the provinces of Trento (1970-89) and Bolzano (1971-90)], and all Italy (1970-89). The aim was to highlight potential differences in mortality trends and promote a more systematic sharing of data and methodologies. METHODS: Death certificates stratified by cause, sex, age and residence were obtained from official publications of the Italian Central Institute of Statistics. Absolute numbers of deaths from different causes, age-standardized rates (on the basis of the European standard population) and percentage of change over the examined period for both sexes were computed for each geographic area. RESULTS: Unfavorable trends were seen for neoplasms of the upper aerodigestive tract, lung, breast, colorectum, bladder, kidney and pancreas and cutaneous malignant melanoma. Increases in most of these neoplasms were more marked in the 4 NE areas than in Italy, especially with respect to cancers of the upper aerodigestive tract in both sexes and cancer of the lung and ovary in women. In Bolzano, rates of neoplasms associated with tobacco and alcohol consumption were lower and less steeply increasing than in the other NE areas, most notably Trento, therefore, contributing to produce the lowest overall cancer mortality rates of NE areas. Cancers of the stomach, uterus, and testis and Hodgkin's disease presented consistent downward trends in all examined areas. CONCLUSIONS: The analysis of mortality trends across areas is consistent with elevated and still increasing cancer rates in the 4 NE areas considered, especially for tobacco and alcohol-related neoplasms and skin melanoma. Preventive strategies, based on epidemiologic knowledge, especially against tobacco and heavy alcohol consumption, and intense intermittent sun exposure, seem to be priorities and may benefit from systematic sharing of information, expertise and intervention tools in NE Italy. At least part of the lack of cancer deaths in Bolzano must be attributable to the deaths of Bolzano residents abroad (especially in Austria) and/or to differences in coding practices. This should be elucidated in future studies.

[7-valent conjugate Pneumococcal vaccine and nasopharyngeal cavity].

7-valent conjugate pneumococcal vaccine is effective for preventing invasive pneumococcal diseases in childhood. The present serotype formulation of the conjugate Pneumococcal Vaccine is effective for preventing 75-90% of the invasive pneumococcal disease cases, depending of the vaccine-serotypes distribution in the several countries. Recent studies, carried out in the north-american context, show that mass vaccination campaign by 7-valent conjugate Pneumococcal Vaccine in childhood, reduce, in vaccinated subjects, the nasopharyngeal colonization by vaccine-serotypes, that are much more joined to antibacterial resistance. This implies non only an active and specific protection for vaccinated, but also for family and community contacts, children and adults. This interesting results, need to be confirmed also in european countries, open a new view for a wider pharmacoeconomic evaluation of the 7-valent conjugate Pneumococcal Vaccine in childhood.

[Dietary habits in primary school children. Role of school meals and parents's social class].

Present paper reports the results of a survey on dietary habits of 1,398 children attending first class of primary school in Trento Province (northern Italy). The following items were investigated: frequency of breakfast and foods intake; frequency of foods at school. The consumption of tracer foods as vegetables, fruit and sweets was also investigated. The results were analyzed according gender, area of residence, teaching method (full time or not) and educational level of parents. The data about nutritional style are satisfactory even if they are strongly associated to education level of parents, above all of the mother. The adequacy of nutritional style is increasing with the increasing of education level. School meal, offering selected foods to all children attending full time teaching section, can re-equilibrate nutritional style, decreasing the differences associated to education level of the parents. Present data can be used for implementing and improving health promotion action on correct dietary habits in childhood, keeping count of the role of education level of the parents.

[Customer satisfaction analysis in women attending an organized mammographic screening. Pilot study at Trento].

Present paper reports on the results of a pilot customer satisfaction study carried out on 1.720 consecutive women (18.7 with spontaneous access) attended senology department (Trento and Borgo) in the context of a organized mammography screening programme, started in October 2000. Data were collected by a questionnarie filled by the women after mammography. 4.3% of the invited women reported the receiving the letter late, 0.9% considered it inaccurate, 7.2% had some problems for getting a new date for test, 1.8% of the whole sample reported some problems for external access and 2.2% for internal access to health facilities; 1.9% perceived waiting room as not friendly. The welcoming by the personnel is judged quite well, only 0.6% complained about it. Trento centre, is more efficient than Borgo. In 21.7% of the cases the mammography has been performed within next 30 minutes of the fixed time and in 7.9% besides that. 36.8% of the whole sample perceived mammography as tiresome and 4.1% as painful. The percentage of women reporting mammography disconforting increase, in Trento sample, according the education level as previously reported. The data about perceived quality are satisfactory, on the whole. Anyway it would be opportune to contain the waiting time.
