Smallpox vaccination and vaccine hesitancy in the Kingdom of the Two Sicilies (1801) and the great modernity of Ferdinand IV of Bourbon: a glimpse of the past in the era of the SARS-COV-2 (COVID-19) pandemic.

OBJECTIVE: The current health emergency caused by COVID-19 disease shows several correspondences with well-known epidemics of the past. The knowledge of their management and overcoming could give us useful tools to face the present COVID-19 pandemic and future epidemics. STUDY DESIGN: On 1 March 1801, the first smallpox vaccinations were carried out in Palermo, and a few weeks later, the vaccine was also administered in Naples and the various provinces of the Kingdom. We aim to study the mass vaccination programme initiated by the Bourbon king Ferdinand IV that was the first large-scale campaign to be conducted in Italy and one of the first in Europe. METHODS: The authors searched and examined historical testimony and different aspects linked to the public health issues on vaccination. It is a topical topic in the current period with the COVID pandemic. RESULTS: Albeit with the due differences determined by the passage of time and by the scientific and cultural advances of modern society, this testimony from the past can provide us with food for thought regarding how to face the present COVID-19 pandemic and to prepare for the future. Indeed, it shows us how the terrible smallpox epidemic was handled and finally overcome, thanks to vaccination.

Nickel dermatitis from earrings 15 years after EU directive implementation: a clinical-epidemiological study and a market survey in Rome, Italy.

BACKGROUND: Nickel (Ni) dermatitis remains a highly prevalent allergic condition in Italy. There is a continuous need for clinical and epidemiological surveillance to evaluate whether or not European Ni Directive has been effective in contact allergy prevention. OBJECTIVES: To assess the prevalence of Ni dermatitis among patch-tested patients and self-interviewed school students and to analyse Ni release from earlobe jewellery. METHODS: Results of patch tests performed in 2006-2007, 2015-2016 and 2017-2018 were retrieved. A questionnaire was compiled by 315 secondary school students. Ni release from earring parts was analysed with the EN1811:2015 method. RESULTS: A significant time trend of decreasing Ni positivity from 2006-2007 to 2017-2018 was observed both in the overall population (44.1% in 2006-2007, 33.0% in 2015-2016, 31.6% in 2017-2018, P < 0.0001) and in female patients (P < 0.0001). Conversely, change was not significant in males (P = 0.16). Decrease was significant for all age groups, except for those aged >60 years (P = 0.51). Among 242 students who reported earring use, 130 (54%) reported symptoms at earlobes, mostly associated with jewellery of materials other than gold and silver (59% of those with earlobe symptoms). Ni release exceeded the migration limit in 4/21 (20%) earring parts. CONCLUSIONS: A high prevalence of Ni dermatitis and earlobe symptoms were found in Rome. A decreasing time trend was noted, with a significant decline in Ni sensitivity compared to the situation observed right after Ni Directive implementation. This most likely represents the consequence of reduced Ni content in earring parts, although a major care in the use of Ni-containing objects could contribute to explain these findings.

Cutaneous manifestations of systemic non-Hodgkin lymphomas (NHL): study and review of literature.

Systemic non-Hodgkin lymphomas are often accompanied by cutaneous manifestations, which are not always looked out for. Nevertheless, these alterations can be very important because their presence is lied to the clinical behaviour of the underlying malignancy, with an early recognition being fundamental. The aim of this study was to make order in this topic and propose a preliminary classification of the cutaneous manifestations associated with non-Hodgkin lymphomas. We performed a retrospective chart review of 62 haematological patients affected by non-Hodgkin systemic lymphomas with dermatological manifestations, who were evaluated from January 2007 to December 2011, and combined these results with a systematic review of Pub medical literature from 1937 to 2011 on this topic. A preliminary classification of these manifestations has been proposed, dividing them in specific and non-specific ones, along with a description of the clinical features and those cases observed in our department. A preliminary approach has been proposed for the study of these manifestations that could be helpful in understanding the biological behaviour and aid early recognition of a flare up in systemic non-Hodgkin lymphomas.

Occurrence of salivary gland tumours in two patients treated with biological agents.

We report two cases of salivary gland tumors arising in two psoriatic patients treated with an anti- TNF-alpha agent. A clear causal relationship could not be established, but the exceptional onset of a bilateral Warthin's tumor in one of these patients should be emphasized.

Vaccine hesitancy, misinformation in the era of Covid-19: Lessons from the past.

Background: As the world has challenged/argued with the Covid-19 pandemic over the last two years, there has been an increase in vaccine misinformation. Although immunity against Covid-19 infection is limited to 4-6 months and requires at least three doses of vaccine to be maximally effective, the current vaccination campaign in industrialized countries shows that vaccinated citizens experience greater immunological protection against severe forms of the disease than unvaccinated citizens. Methodology: A perusal of the literature was performed in order to reconstruct the communication methods applied in the managing of the Covid-19 pandemic; the management of the current pandemic was compared with the management of another scourge of the past: poliomyelitis. Results/Discussion: In order to raise public awareness on public health issues, it is essential that governments and institutions communicate scientific data to all sections of the population in an unambiguous way. In this sense, it is essential to apply "prebunking", which is a layered defense system available to society that prevents misinformation before it is spread. This is to avoid the subsequent debunking of false information, which generates insecurity and fuels fears. Belief in medical misinformation represents a meaningful problem for public health efforts to fight Covid-19 through vaccination. Conclusion/Perspectives: In this sense an example of proper management of one of the many epidemics of the recent past, poliomyelitis, should make us reflect on the effectiveness of past approaches. This testimony from the past can provide us with food for thought regarding how to face the present Covid-19 pandemic and to prepare for the future. Certainly, it shows us how the awful pandemics/epidemics from the past was handled and finally overcome, despite perceived risk and vaccine hesitancy.

Tuberculosis in Siena: evolution of the disease and its treatment, from the Unification of Italy to the 1930s.

Between the end of the nineteenth century and the first half of the twentieth century, the city of Siena experienced elevated tuberculosis-related morbidity and mortality, to the point that on January 1, 1929 the newspaper La Nazione wrote that "Siena ranks second in the official Tuberculosis (TB) incidence rate". The author presents statistical data relating to a time span ranging from 1898 to 1935, interpreting them in light of social and sanitary conditions found in the city. The result is an exhaustive picture of the most important actions implemented at city level to prevent tuberculosis and to assist and treat the sick, such as: the creation of seaside hospices conceived by Carlo Livi for children suffering from scrofula, as well as centers committed to the prevention of childhood poverty and malnutrition; the realization of activities in the green areas of the ramparts of the Fortress, upon recommendation by the great hygienist Achille Sclavo; the establishment of a Preventorium on the premises of the Monastery of Santa Maria Maddalena to accommodate children from families that included pulmonary tuberculosis patients, and countless activities carried out by the Anti-TB Dispensary. Of particular interest is the identification of the main cause of high TB incidence in the unhealthy houses located in some areas of Siena's district, which, in 1930 engendered a lively debate hinging upon the notion of building restoration.

[Workers with alcohol and drug addiction problems. Consensus Document of the Study Group on Hazardous Workers]. / Lavoratori con problemi di alcol e dipendenze. Documento di Consenso del gruppo La.R.A. (Lavoratori Rischiosi per gli Altri).

BACKGROUND: Italian Law 81/08 (so-called "Unified Text of Laws on Health and Safety at Work"), came into force on 15 May 2008 and incorporates provisions related to medical surveillance of drug and alcohol dependency at the workplace. OBJECTIVES: Occupational health traditionally addresses the issue of protection of worker from occupational hazards. The issue of protection of third parties from behaviour of workers resulting from drug and alcohol dependency implies an original methodological approach, involving full cooperation of employer, employees, and health and safety consultants. METHODS: A consensus development meeting was organized under the leadership of the Italian Study Group on Hazardous Workers (La.R.A. group). The meeting brought together physicians of different specialties, legal experts and bioethicists, labour and management policy-makers, to discuss the issue and define the research data available, the standards that were appropriate, and which policies were fair. RESULTS: The efficacy of medical surveillance, including workplace drug-testing, relies on a comprehensive policy, including written and verbal information on the use of alcohol and drugs on the job, training for supervisors and management, employee education, and employee assistance structures. Sample collection and testing should be carried out in accordance with standardized and tested procedures. Small businesses will need assistance, including development of model policies, setting up consortia for testing services and if necessary request for National Insurance benefits to reduce costs. CONCLUSIONS: The recently introduced Italian legislation on occupational safety and health closely resembles Finnish law since it consists of a "double channel" for workplace drug testing. At recruitment, the employer is entitled to ask a job applicant for a certificate of "Job fitness", including drug tests, that can be issued only by a public health institution, where the job applicant works on a well-defined set of tasks which require accuracy, trustworthiness, independent judgement or a very good reaction capacity. The employer may also refer the employee to the public health institution to obtain a certificate in the course of an employment contract when there is a legitimate suspicion that the employee is working while under the effects of drugs or alcohol or that the employee is a drug addict. After recruitment, the physician responsible for medical surveillance of workers (the so-called "Competent Physician") is entitled to perform drug tests on employees. The need for a test is decided by the health care professional, not by the employer, and only a general report on the health of the employee ("fit", fit with restrictions" or "unfit") may be given to the employer. Workers positive for drug tests will be referred to a public health institution for re-testing and treatment.

Voluntary termination of pregnancy: An opportunity for Measles, Mumps and Rubella vaccination in an Italian healthcare local unit.

In Italy, the National Plan for the Elimination of Measles and Congenital Rubella 2010-15 suggests offering Measles, Mumps and Rubella (MMR) vaccination to susceptible women who underwent voluntary termination of pregnancy (VTP) In Rome, S. Eugenio Hospital is one of the structures where VTP is practised in an Operative Unit called "Family Planning" The primary goal of this study was to estimate the prevalence of susceptibility to rubella, using IgG and IgM immunoassays, among women accessing VTP and to offering MMR vaccination to susceptible women. Secondarily, this study evaluated acceptance of the vaccination offer From 2013 to 2015, data were collected from 1513 voluntary termination of pregnancy (VTP) cases The results show a significant increase of 5 percent in susceptibility prevalence in the target group from 13.6% in 2013 and 2014 to 18.4% in 2015 The association between rubella susceptibility and age was statistically significant (p<0.01) Throughout the entire period, acceptance of the vaccine proposal was 19% (45/232) among susceptible women; 58% (135/232) refused the vaccine and 23% (52/232) took time to think about it This study shows an increase of 5 percent in the prevalence of rubella susceptibility over two years. This result is worrying, even considering the short span of the data collection The rate of acceptance of vaccination is unsatisfactory considering the possibility of future pregnancies This issue deserves continued action, which, going forward, might transform a "project" into a shared strategy as part of a wider network with the goal of aligning Italy with international recommendations.

A syndrome of pathological left-handedness. Correlates of early left hemisphere injury.

A pattern of correlative changes in lateralization in individuals with known or suspected brain injury recently has been advanced as the syndrome of pathological left-handedness (PLH). This syndrome, which is believed to be caused by an early left-sided cerebral lesion, may include asymmetric motor and/or trophic changes on the right side of a body part in addition to changes in higher-level cognitive processing abilities. Several clinical case studies have provided support for such a syndrome. Despite their clinical subject to inherent biases of selection. The present study was therefore designed to evaluate the PLH syndrome in a systematic fashion by using a large number of brain-injured and normal subjects. The incidence of each of the putative elements of the PLH syndrome was investigated. The results suggest that traits such as atypical cerebral speech representation, motor impairment of the nondominant hand, and hypoplasia of the right foot are salient features of the syndrome. The results are discussed with reference to clinical diagnostic implications.

Some correlates of intra- and interhemispheric speech organization after left focal brain injury.

Determinants of inter- and intrahemispheric organization following left focal injury were examined with data deriving from four different studies that used three different assessment methods (amobarbital, temporal lobectomy, dichotic listening). With regard to interhemispheric reorganization, the results revealed that the earlier the lesion onset, the higher the probability of a biomodal hemispheric reorganization (speech and hand). A unimodal reorganization (speech only) was tied to a later occurring lesion, but one before age six. Furthermore, interhemispheric speech reorganization was associated with an early lesion onset while intrahemispheric speech maintenance was linked to a later lesion onset. The results are discussed in terms of hemispheric plasticity and functional maturity.

The role of familial sinistrality in cerebral organization.

The literature on the relationship between familial sinistrality (FS) and laterality is conflicting. A large scale investigation employing multiple measures of laterality assessment and rigorous methods of handedness and FS determination was conducted with a normal population of left- and right-handers. The results failed to find a relationship between FS and hemispheric representation of speech despite the fact that a robust relationship was found between handedness and hemispheric speech specialization. Possible reasons for these null findings are discussed.

Handedness patterns in autism suggest subtypes.

The present study reports preliminary data from two unselected samples of carefully diagnosed autistic subjects (children and adults) and an assessment procedure that includes a large sample of items, appropriate for lower-functioning autistic subjects, with multiple presentations within and between sessions 1 week apart. The study seeks to determine (1) whether a raised incidence of non-right-handedness exists in these samples (2) if so, what constructs best represent this shift in the handedness distribution (i.e., phenotype and CNS substrate) and (3) whether these handedness phenotypes are associated with different levels of cognitive functioning. The results reveal a dramatic shift away from right-handedness in both autistic samples, due to a raised incidence of two phenotypes, manifest left-handedness and ambiguous handedness. The ambiguously handed, who were postulated to represent substantial bilateral CNS pathology due to early brain injury, were found to have much lower intellectual scores in one of the study samples.
