ABSTRACT

BACKGROUND: Aetiology of childhood leukaemia and childhood neoplasm is poorly understood. Information on the prevalence of risk factors in the childhood population is limited. SETIL is a population based case-control study on childhood leukaemia, conducted with two companion studies on non-Hodgkin Lymphoma (NHL) and neuroblastoma. The study relies on questionnaire interviews and 50 Hz magnetic field (ELF-MF) indoor measurements. This paper discusses the SETIL study design and includes descriptive information. METHODS: The study was carried out in 14 Italian regions (78.3% of Italian population aged 0-10). It included leukaemia, NHL and neuroblastoma cases incident in 0-10 year olds in 1998-2001, registered by the Italian Association of Paediatric Haematology and Oncology (AIEOP) (accrual over 95% of estimated incidence). Two controls for each leukaemia case were randomly sampled from the Local Health Authorities rolls, matched by gender, birthdate and residence. The same controls were used in NHL and neuroblastoma studies. Parents were interviewed at home on: physical agents (ELF-MF and ionizing radiation), chemicals (smoking, solvents, traffic, insecticides), occupation, medical and personal history of children and parents, infectious diseases, immunizations and associated factors. Occupational exposure was collected using job specific modules. ELF-MF was measured in the main rooms (spot measurement) and close to child's bed (48 hours measurement). RESULTS: The study included: 683 leukaemia cases (87% ALL, 13% AnLL), 97 NHL, 155 neuroblastomas, and 1044 controls. CONCLUSIONS: SETIL represents a data source on exposure of Italian children to a broad array of potential carcinogenic factors.

ABSTRACT

OBJECTIVES: High Toscana virus (TOSV) antibody seropositivity rates have been documented in the last decade, especially in the Mediterranean area. It is unclear if these rates are associated with a recent or past exposure to the virus. This is of importance, as primary infection can cause neurologic complications, especially in adults. The aim of the present study was to assess the current active TOSV circulation in western Sicily. METHODS: A cross-sectional seroprevalence study was conducted on 271 individuals aged 4-92 years, sampled from the general population of a small city. Each participant completed a self-administered questionnaire and provided serum, which was analyzed for the presence of specific anti-TOSV IgM and IgG. RESULTS: Anti-TOSV IgM was detected in eight (3.0%) participants, of whom only three had anti-TOSV IgG. The prevalence of anti-TOSV IgM was highest in subjects aged 25-34 and 35-44 years (7.1% and 4.8%, respectively). All subjects positive for anti-TOSV IgM were resident in the suburban area. CONCLUSIONS: The detection of IgM documented the circulation of TOSV, a Phlebovirus, in a random population sample of Sicilian adults. The highest risk of TOSV seroconversion in subjects living in the suburbs appears to suggest a high density of TOSV vectors in peri-urban areas.

ABSTRACT

OBJECTIVE: The present study aimed to assess seroprevalence of and risk factors for Toscana (TOSV) and Sicilian (SFSV) virus infections in a sample of Sicilian subjects. METHODS: A cross-sectional seroepidemiological study was conducted on 271 individuals. Each participant completed a self-administrated questionnaire and provided a serum sample which was analyzed for the presence of IgG specific anti-TOSV and anti-SFSV viruses. RESULTS: Overall, 90 subjects (33.2%) were positive for TOSV IgG, 25 (9.2%) were positive for SFSV IgG and 11 (4%) were positive for both the viruses. A higher risk for TOSV seropositivity was found in participants who were older (adjOR = 1.02 per year; 95% CI = 1.01-1.03), having a pet living outdoors (adjOR = 2.62; 95% CI = 1.42-4.83) and being obese (adjOR = 2.37; 95% CI = 1.06-5.30). CONCLUSIONS: TOSV seroprevalence appears to be relatively high in Sicilian general population, especially in older adults, representing a potential public health concern. The observations that seropositivity for TOSV was not significantly associated with SFSV seropositivity, and none of the risk factors associated with TOSV were associated with SFSV seem to suggest that these two phleboviruses may have different ecology and transmission pathways.

ABSTRACT

To assess whether arthropod bites promote Kaposi sarcoma (KS), we determined the seroprevalence of Sicilian (SFSV) and Toscana (TOSV) phlebovirus antibodies in 30 patients with classic KS and 100 controls in Sicily. Nine (6.9%) subjects, all controls, were positive for SFSV, whereas 41 (31.5%) were positive for TOSV. Seroprevalence with immunoglobulin (Ig) M or IgG against either virus was significantly higher in controls (43% vs 13.3% in case patients; P < .01). Adjusted for age, IgG seroprevalence was significantly lower in KS patients compared to controls (adjusted odds ratio, 0.22; 95% confidence interval, .07-.72). Low phlebovirus seroprevalence in patients with KS may reflect incapacity to produce robust, persistent antibody responses, and suggests that arthropod bites do not promote KS.

ABSTRACT

BACKGROUND: Powdered infant formula (PIF) is not a sterile product, but this information appears to be poorly diffused among child caregivers. Parents and child care workers may behave in an unsafe manner when handling PIF. METHODS: This study involved parents and child care workers in the 24 municipal child care centres of Palermo. Knowledge and self-reported practices about PIF handling were investigated by a structured questionnaire. A Likert scale was used to measure the strength of the respondent's feelings. Association of knowledge and self-reported practices with demographic variables was also evaluated. RESULTS: 42.4% of parents and 71.0% of child care workers filled in the questionnaire. Significant differences were found between parents and child care workers for age and education. 73.2% of parents and 84.4% of child care workers were confident in sterility of PIF. Generally, adherence to safe procedures when reconstituting and handling PIF was more frequently reported by child care workers who, according to the existing legislation, are regularly subjected to a periodic training on food safety principles and practices. Age and education significantly influenced the answers to the questionnaire of both parents and child care workers. CONCLUSION: The results of the study reveal that parents and child care workers are generally unaware that powdered formulas may contain viable microorganisms. However, child care workers consistently chose safer options than parents when answering the questions about adherence to hygienic practices.At present it seems unfeasible to produce sterile PIF, but the risk of growth of hazardous organisms in formula at the time of administration should be minimized by promoting safer behaviours among caregivers to infants in both institutional settings and home.

ABSTRACT

An increasing number of internationally adopted children is coming to Italy, and their immunization status is unknown. We evaluated the immunization status of such children in Palermo, Italy. We searched for the presence of a BCG scar in 88 children, 49 boys and 39 girls (mean age 76+/-32 months), most of whom (98%) came from Eastern Europe. Presence of BCG scar was observed in 59 (67.1%) of them, included five children without any pre-adoptive medical records. Twenty-three out of 29 children without any evidence of BCG scar were tested by Mantoux. Seven (30.4%) of 23 were tuberculin positive and diagnosed as having latent tuberculosis infection. We also examined immunization status against poliovirus 1-3, tetanus, diphtheria, pertussis, measles, mumps, rubella and hepatitis B of 70 internationally adopted children and we compared it with the pre-adoptive immunization records of their birth country. Protective titers (>1:8) against poliovirus 1-3, were found respectively in 67.1%, 91.4%, 42.8% of 70 immunized children, and only 38.5% of them had at the same time full protection against all three types of poliovirus. Protective titers against tetanus and diphtheria were found in 91.4% and 95.7% of 70 vaccinated children. Presence of antibodies against pertussis, measles, mumps and rubella was observed respectively in 16 (32.6%) of 49, 40 (62.5%) of 64, 28 (56%) of 50 and 24 (85.7%) of 28 children who had received the vaccine. As regards hepatitis B, only 20 of 29 vaccinated children had detectable hepatitis B surface antibodies, while four of 29 vaccinated and two of 41 not vaccinated children were positive for both hepatitis B surface antibodies and hepatitis B core antibodies. Finally three of 41 not vaccinated children were both hepatitis B surface antigen and hepatitis B core antibodies positive. No relation was found between health status and immunization and between age and antibody positiveness of vaccinated children except for hepatitis B, therefore the youngest immunized children were more likely to be hepatitis B surface antibodies positive. Our data suggest that internationally adopted children should be tested for their immunization status on arrival in the adopting country, because they are not protected in a sufficient way against vaccine-preventable diseases and their pre-adoptive immunization records sometimes are lacking and frequently are scarcely reliable.
