Knowledge and behaviour of nursing students on the prevention of healthcare associated infections.

INTRODUCTION: Hospital infections, or "healthcare associated infections" (HAI) represent the most common and serious complications of healthcare. Adoption of safe care practices able to prevent or control the transmission of infections, both in hospitals and in other healthcare settings is crucial. The aim of the study is to assess the awareness about the risk factors and the most effective measures of prevention of HAI in the University of Ferrara nursing school students, giving particular attention to the hand hygiene practices and the use of standard precautions. METHODS: 339 students attending all the three years of course of the same academic year were enrolled. An anonymous questionnaire was administered in order to investigate the knowledge about three specific areas: infections associated with healthcare practices (HAI), standard precautions (SP) and hand hygiene (HH). RESULTS: A sufficient level of knowledge by all the three groups of students was observed only in the SP area. A barely sufficient score was reached only by the third year students with regard to the proper HH. The level of knowledge about HAI was inadequate. CONCLUSIONS: A periodically check of nursing students' knowledge would be advisable in order to fill any gaps, improve training, reduce HAI and increase prevention measures compliance.

The burden of HPV-related diseases in Italy, 2001-12.

Background: Human papillomavirus (HPV) infection is the main cause of cervical cancer and plays a relevant role in the development of genital warts and of the cancer of penis and anus, head/neck, oropharynx and genitourinary system. The aim of this study is the evaluation of hospitalizations due to HPV-related pathologies in 2001-12 in Italy. Methods: The national hospital discharge forms were provided by the Ministry of Health. The HPV-related hospitalizations were identified using specific diagnostic codes, accordingly to the ICD-9-CM coding system. The proportion of hospitalizations of potentially HPV-related pathologies, obtained from the literature, was evaluated as well as the hospitalization rates (hr) and their trend over time. Results: Uterine cervical cancer and CIN III accounted for 40% of hospitalizations (hr: 15.6/100 000 and 17.6/100 000, respectively). Head/neck and oropharynx pathologies accounted for 24.5% of cases (hr: 16/100 000 and 3.9/100 000, in males and females, respectively), followed by genital warts (17.3% of hospitalizations; hr: 7.5/100 000 in males and 8.52/100 000 in females), anal (8.1% of hospitalizations), genitourinary (7.7%) and penis cancers (2.2%). Conclusions: The study, even if limited to the evaluation of hospitalizations, points out how HPV-related pathologies continue to be a relevant public health issue in Italy with a high impact on population.

Epidemiology of Neisseria meningitidis infections: case distribution by age and relevance of carriage.

Notwithstanding different meningococcal serogroups have changed their distribution and their impact in different age classes over time, N. meningitidis' invasive diseases are a major public health issue worldwide, due to the related complications and severe sequelae. Nowadays, the highest rates of invasive disease are registered in children younger than 1 year of age, with a second lesser peak in adolescents and young adults (15-25 years of age). On the contrary, the prevalence of carriage is low in newborns and in school-age children, and increases during adolescence and young-adult age; then it decreases again in older age. N. meningitidis' infection prevalence has greatly decreased in Europe and North America thanks to the use of conjugate vaccines (MenC and MenACWY) as well as the incidence of invasive disease due to serogroup A in sub-saharian Africa after the introduction of MenAfriVac conjugate vaccine. The great success of conjugate vaccines is related not only to the direct protection from disease but also to the impact on carriage; this latter allows an indirect protection of unimmunized subjects. For these reasons, the implementation of immunization with the new generation vaccines in the age classes most impacted by disease and carriage (first year of life, adolescence and young adulthood) could permit to achieve an extraordinary decrease of the incidence of meningococcal disease.
