May a comprehensive mineralogical study of a jackstone calculus and some other human bladder stones unveil health and environmental implications?

This paper represents the first result of an active collaboration between the University of Sannio and the San Pio Hospital (Benevento, Italy), started in the 2018, that aims to a detailed mineralogical investigation of urinary stones of patients from Campania region. Herein, selected human bladder stones have been deeply characterized for clinical purposes and environmental biomonitoring, focusing on the importance to evaluate the concentration and distribution of undesired trace elements by means of microscopic techniques in the place of conventional wet chemical analyses. A rare bladder stone with a sea-urchin appearance, known as jackstone calculus, were also investigated (along with bladder stones made of uric acid and brushite) by means a comprehensive analytical approach, including Synchrotron X-ray Diffraction and Simultaneous Thermal Analyses. Main clinical assumptions were inferred according to the morpho-constitutional classification of bladder stones and information about patient's medical history and lifestyle. In most of the analyzed uroliths, undesired trace elements such as copper, cadmium, lead, chromium, mercury and arsenic have been detected and generally attributable to environmental pollution or contaminated food. Simultaneous occurrence of selenium and mercury should denote a methylmercury detoxification process, probably leading to the formation of a very rare HgSe compound known as tiemannite.

Addressing the anti-vaccination movement and the role of HCWs.

Over the last two decades, growing numbers of parents in the industrialized world are choosing not to have their children vaccinated. Trying to explain why this is occurring, public health commentators refer to the activities of an anti-vaccination movement. The aim of this paper is to review the literature about the anti-vaccination movements and to highlight the knowledge and the skills needed for HCWs to fight against their ideas. The main theoretical structures of anti-vaccination ideology in the 19th and 20th centuries are: vaccines cause idiopathic illness; opponents against vaccines accused vaccine partisans to be afraid of the "search after truth," they fear unveiling errors; the vaccination law not only insults every subject of the realm, but also it insults every human being; vaccine immunity is temporary; an alternative healthy lifestyle, personal hygiene and diet stop diseases. Proponents against vaccination now have additional means to communicate their positions to the general public, the Internet in particular. Doctors and HCWs constantly have to face parents and patients who search information about vaccination. A lot of these people have previously found data about vaccinations from a lot of sources, such as papers, media or in websites and in these sources most contents come from anti-vaccine movements. For these reasons doctors and HCWs need to have updated knowledge about the vaccinations and to know the contents proposed by vaccine sceptics. Educating the general public cannot be fully effective unless there is a corresponding provision, enthusiasm and commitment by trained HCWs.

[Opinions of women regarding a planned home birth project in Apulia (Southern Italy)]. / Opinioni della popolazione femminile su un possibile programma di parto domiciliare in Puglia.

A growing desire among women to move away from interventions and hospitals to more "natural" childbirth has emerged over several years. The role and autonomy of midwives, a favourable opinion among women about home childbirth and better cooperation between hospitals and district health facilities are all fundamental in order to implement a home birth project. The opinion of women about "planned" home birth was investigated in the Puglia region through a survey conducted among a sample of women who had just delivered in hospital and a representative sample of the general female population. From 20 to 30% of women in the Puglia region would be basically in favour of home birth project. The main difference between the two groups of women concern the higher proportion of caesarean deliveries among mothers who had just delivered and their demand for more specific training of involved health personnel. Both samples are agreed on the specific training of women during pregnancy and on the presence of a specialist during home delivery. The results of the investigation seem to be in favour of planning a home birth project in the Puglia region.

From hepatitis B to hepatitis A and B prevention: the Puglia (Italy) experience.

The incidence of hepatitis B virus infection in Italy is 10 per 100, 000 population, with most cases occurring in young adults. Vaccination against hepatitis B has been compulsory since 1991 for all newborns and 12-year-olds. In the Puglia region, this programme has reduced the incidence of hepatitis B from 7.4 per 100,000 population in 1990 to 2.4 per 100,000 population in 1996. The number of notified cases of hepatitis B in Puglia decreased from 212 in 1992 to 73 in 1997. As 50% of these cases occurred in young adults, the main aim of the current vaccination programme is to achieve high coverage rates among teenagers and young adults within the next few years. Although the incidence of hepatitis A is only about 5 per 100, 000 overall in Italy, Puglia is an area of intermediate endemicity with a seroprevalence of antibodies to hepatitis A virus (anti-HAV) of about 40% in 18-year-olds. The incidence of hepatitis A is up to 30 per 100,000 between the periodic outbreaks that occur every 2-4 years. Most notified cases occur in adolescents and young adults. The last outbreak of about 11,000 cases of hepatitis A in the Puglia region occurred in 1996-1997, mainly in the summer months in towns with harbours or near the coast. The most important risk factor was initially consumption of raw seafood, but later was personal contact, probably between children. A vaccination programme against hepatitis A was initiated in Puglia in 1997, aiming to vaccinate all infants of 15-18 months and all 12-year-olds against hepatitis A. Infants receive monovalent hepatitis A vaccine with the first dose of mumps/measles/rubella vaccine. Monovalent hepatitis vaccine can be given with the second and third doses of hepatitis B vaccine in 12-year-olds, but use of combined hepatitis A and B vaccine is recommended to aid compliance and reduce the commitment of physician/nurse time. Vaccination can be performed in school.
