Attitude of Health Care Workers (HCWs) toward Patients Affected by HIV/AIDS and Drug Users: A Cross-Sectional Study.

Caring for HIV/AIDS patients and/or drug users requires health care workers (HCWs) to have good knowledge of the issues. Cultural differences in HCWs, combined with professional ethics and personal beliefs, could also result in conflicting attitudes, leading to difficulties related to looking after people affected by HIV/AIDS or drug users. A cross-sectional study was carried out to assess the attitude towards HIV/AIDS patients and/or drug users in a sample of workers operating in a large university hospital in southern Italy. A total of 736 workers were surveyed from May to November 2016. During the periodic occupational health surveillance, a questionnaire was administered about attitudes of discrimination, acceptance and fear towards these patients. Respondents showed average levels of acceptance to HIV/AIDS and drug user patients. As years of experience and professional training increased, scores for discrimination, acceptance of HIV/AIDS, acceptance of drug users and fear decreased. Factors positively influencing levels of attitudes were being female and younger. Supplementary education is needed to strengthen the awareness of HCWs.

[Monitoring of heavy metals and trace elements in the air, fruits and vegetables and soil in the province of Catania (Italy)]. / Monitoraggio di metalli pesanti ed oligoelementi in aria, ortofrutta e terreno nella provincia di Catania.

Contamination of fruits and vegetables with heavy metals can result from anthropogenic events (car or factory emissions, poor management of sewage and industrial waste) or from natural events (volcanic activity and geological soil matrix). The chemical and toxicological characteristics of heavy metals can have an impact on human health through several mechanisms. Other metals, on the other hand, are essential for maintenance of physiological and biochemical human processes, are protective against many diseases and must be present in the diet because they cannot be synthesized by the human body. The purpose of this study was to assess the presence of heavy metals and trace elements both in fruit and vegetable products widely consumed in the province of Catania (Sicily, Italy) and in various environmental matrices (air, water and land), and to investigate possible sources of contamination. Fruit and vegetable products (tomatoes, lettuce, spinach, eggplants, potatoes, zucchini, grapes, apples and pears) were sampled (n = 60) from the towns of Adrano, Biancavilla and Mazzarrone. These locations were selected for their geomorphology, climate and cultivation characteristics. Levels of lead, cadmium, nickel, copper, zinc, vanadium and selenium in fruit, vegetables, air and water samples were determined using atomic absorption spectrometer with graphite furnace Perkin-Elmer AAnalyst 800 while soil samples were evaluated by the atomic emission spectrometer Optima 2000 DV Perkin-Elmer. The presence of mercury was evaluated by atomic absorption spectrometry with cold vapor technique. Study results revealed widespread contamination of fruit and vegetables and mainly due to use of fertilizers and to volcanic activity. A strategy targeting the entire food chain is essential for ensuring food safety and consumer protection and maintaining contaminants at levels which are not hazardous to health.

[Efficacy of the analytic approach in evaluation of biofilter activity in a composting system]. / Efficacia dell'approccio analitico nella valutazione dell'attività del biofiltro di un impianto di compostaggio.

Composting may present certain technical problems which can negatively influence results in terms of environmental impact as well as of profit and loss account. The aim of this study was to estimate the efficacy of the analytic approach to evaluate the effect of removing the biofilter in a composting system. Results have shown the presence of foul-smelling emissions despite the fact that concentrations of investigated substances were well below the danger threshold or even below the method's detection threshold. Therefore, besides the analytic approach, the most reasonable choice seems to be introducing a reference method for evaluating odour emissions and the efficacy of composting systems.

[Evaluation of biological indicators of hygienic quality in modern dental clinics with a high perceived quality in Catania (Italy)]. / Risultati dell'applicazione di indicatori biologici di qualità nella valutazione di ambulatori odontoiatrici con caratteristiche strutturali e criteri di gestione moderni.

A study was performed to evaluate safety and hygienic quality levels in dental clinics in Catania (Sicily, Italy). Microbiological checks of air samples, surfaces and water were performed in seven modern dental clinics with a high perceived quality of care. In total, 16 active dental units were present in the clinics included in the study. Water samples were obtained from dental air-water syringes and directly from the water supply and analyzed to determine aerobic mesophilic bacteria counts, coliform counts and number of legionella unit-forming-colonies. The BART™ system was used to identify Pseudomonas spp. and other biological indicators. Critical levels of one or more indicators were found in the water circuits. In particular, Legionella pneumophila was found in five dental units, associated with Pseudomonas spp., high mesophilic aerobic bacterial counts and the presence of slime-producing bacteria. The results indicate the need for hygienic quality control checks through the use of appriopriate biological indicators, even in dental clinics with a high perceived quality.

[Drug resistance in endemic and imported tuberculosis cases in Sicily (Italy)]. / Farmacoresistenza in casi di tubercolosi endemici e di importazione in Sicilia.

This study was performed to evaluate the prevalence of anti-tuberculosis (TB) drug resistance in Sicily (Italy). A total of 92 Mycobacterium tuberculosis strains were tested, 43 of which were isolated from outpatients between 2004 and 2007 and 49 isolated from patients hospitalized in various eastern Sicilian hospitals. The 92 strains were all isolated from adult patients (mean age 56 years), 71 of which were Italian and the remaining 21non-Italian. Drug sensitivity testing was performed by using the Canetti proportion method and revealed a large proportion of strains (48.9%) found to be resistant to one or more drugs. The most frequent type of resistance was found to be towards rifampicin (38%). Simultaneous resistance to rifampicin and isoniazid, which characterizes multi-drug resistant TB (MDR-TB), was observed in 19.5% of strains; this was always associated with resistance to at least one other anti-tuberculosis drug. No significant differences were found in the distribution of drug resistance, including multi-drug resistance, between strains isolated from Italian and non-Italian patients. A higher percentage of resistance was found amongst strains isolated from hospitalized patients with respect to those from outpatients: rifampicin 53% vs 21%; isoniazid 41% vs 9%; Mdr-TB 47% vs 12%.

[Cutaneous leishmaniasis in Catania (Italy): persistently endemic and underestimated]. / Leishmaniosi cutanea: una endemia persistente e sottostimata.

Cases of cutaneous leishmaniasis diagnosed at the laboratory of Department of Hygiene of the University of Catania (Italy), from 1998-2007 were evaluated. Specifically, demographic and personal data, area of origin and temporal trend of the 97 cases confirmed by microscopy in this 10-year period were examined. The data collected shows that the disease is still widely present in this area ; on the other hand official data regarding this disease appears incomplete and shows various inconsistencies. This is due to underreporting but also to scarce knowledge of the disease by physicians. Elimination of cutaneous leishmaniasis can be achieved by controlling leishmaniasis in dogs and improving environmental conditions; this requires greater efforts not only by institutions but also by individuals.
