On the benefits of wearable devices for Parkinson's disease.

ABSTRACT: Freezing of gait (FOG) is defined as episodic inability to generate an effective movement without any known cause other than parkinson-ism or gait disturbance. FOG is one of the most disabling symptoms of Parkinson's disease (PD), it affects mobility and increases the risk of falling in people with PD, making it a leading cause of hospitalization and of significantly worsening the quality of life (1). In recent years, new non-invasive intervention strategies have been implemented to decrease FOG symptoms. Thanks to technological progress, several devices have been developed as a support for the patients during diag-nosis, treatments and also everyday life. These types of interventions are based on cueing systems that rely on active stimulation. These devices are able to identify FOG states and to operate when this motor blocks occur, providing external stimuli to overcome these episodes. Hence, this work aims to provide a technological review of the literature related to wearable devices and focuses on auditory, visual, virtual and soma-tosensory cueing systems, which can provide a suitable intervention for patients with PD. The paper describes the technical functioning and effectiveness of the different reporting systems in overcoming FOG episodes. Moreover, a classification of existing devices, highlighting their advantages and disadvantages, will be provided in order to identify the ones with the best performance.

Reliability of adapted version of Italian Label tobacco Impact Index for the adolescent: ALII.

OBJECTIVE: The aim of this study is to assess the reliability of the Adolescent Label Impact Index (ALII) , it is an adolescent adapted version of Italian LII of the tobacco products warnings. MATERIAL AND METHODS: A sample including students aged 13-15 years was considered. The ALII is constructed by 4 items: salience, harm, quitting and forgo. The questionnaire was self-administered to study participants twice with 3 days between each administration (T1 and T2) to measure reliability. The internal consistency using Cronbach's alpha and Corrected Item-Total Correlations (CITC) and the test-retest reliability applying Pearson's correlation were computed. RESULTS: Cronbach's alpha ranges from 0.625 at T1 to 0.715 at T2. The "salience" resulted the item with the lowest CITC value (=0.281). The Pearson's coefficient was r=0.909 (p<0.001). CONCLUSIONS: The instruments is low in cost and easy to administer and analyses in a setting people aged 13-15 years. The ALII shown an acceptable consistency and excellent stability over time. However, attention has to be paid when the ALII is administered to the no smoking teens and who has never seen the tobacco product labels to allow an appropriate interpretation of the data collected.

[The childhood home accidents: risk perception and behavior].

OBJECTIVE: The aim of the study was to assess the frequency and the kind of home injuries among the children and to have information on the sources of risk and hazardous behaviors in the home setting. METHODS: An anonymous questionnaire was administered to parents. In order to evaluate the risk perception in relation to the home environment, drawings to color were administered to children in kindergarten and to those of the first cycle of elementary school. A questionnaire was administered to older pupils. Statistical analyses were performed using the statistical program EPIINFO. RESULTS: The most risky behaviors showed by about half of parents were to cook lunch and doing other works in the house, cook with children in the kitchen. 28.0% said that sometimes left unattended appliances. Discordant opinions were found on the possibility of having injuries at home, in fact, 39.7% of parents affirmed that their son was victim of a home injury, compared with 64.0% of children. The number of children victims of home injuries was significantly higher among those aged between 6 and 10 years. DISCUSSION: Our search was in according with the national trend of the types and outcomes of home injuries, and confirms the existence of relationship between low educational level and higher frequency of injuries in childhood. Although prevention was considered an invaluable tool by parents to ensure the child's safety from the earliest years of life in this way, this study highlights the urgent need to take preventive action to develop an adequate safety culture.

[Survey of the presence of Listeria monocytogenes in meat products sold in retail]. / Indagine sulla presenza di Listeria monocytogenes in prodotti carnei venduti al dettaglio.

The present study evaluates the presence of Listeria spp and particularly of L. monocytogenes in bovine, pork and poultry meats sold by retail in supermarkets and butchers in the city of Cassino. The sensibility to the antibiotics mostly used in the veterinary practice has been tested on the isolated strains. The different species of Listeria have shown a considerable variation of isolation based on the meat's typology and on the different store's provenance. Moreover our results show greater degree of contamination than the data currently available the Italian literature. In our study poultry meat is the most contaminated one. We can assert that omissions and poor caring errors in the manipulation and conservation of meat expose the customer to an even higher risk of infection.

Preventable infectious diseases using vaccination in developmental age in the province of Frosinone, Italy.

INTRODUCTION: A study has been made of the behaviour of preventable infectious diseases by means of vaccination in the developmental age, reported between 1995 and 2003, in the area of Frosinone and Province, Italy. RESULTS: . Analysis of the distribution of the 185 cases of hepatitis B notified, demonstrates that the mean age has increased from 26.5 to 41.1 years. Notifications of invasive diseases due to haemophilus influenzae type b (Hib) refer exclusively to 13 cases of meningitis. As far as concerns pertussis, 119 cases have been reported (median age 4.0 years, mode 1.0). Overall 850 cases of measles were reported (median age 7.0 years, mode 5.0), the highest number being recorded in 1997 (349 cases: median age 7.0 years, mode 5.0) and 2002 (199 cases: median age 8.0 years, mode 8.0). Rubella occurred in 411 cases (median age 12.0 years, mode 11.0), with 53.3% involving females. As far as concerns mumps, the last peak of the epidemic occurred in 2001 (median age 7.0 years, mode 6.0) with 137 cases. DISCUSSION AND CONCLUSION: Results emerging from the study demonstrate a reduction in time in the number of notifications for almost all the diseases under consideration. The distribution of the cases of rubella infertile females, in 2002, stresses the need to promote campaigns in order to recuperate still-susceptible women of childbearing age. The cases of hepatitis B, pertussis and meningitis due to Hib confirm the high rate of protection resulting from vaccination. The incidence rates of measles, mumps, rubella and pertussis when compared with those of the paediatric sentinel surveillance system (SPES) clearly demonstrate not only that these are underestimated but also reveal controversial findings with respect to data provided by Infectious Diseases Italian Surveillance System (SIMI).

Alter Ego. Drug and brain--information to prevent. Compared analysis of opinions, knowledge and habits among a multicentric sample of secondary school students about drug addiction.

Repression and control have been shown to be inadequate for drug addiction issues. Recent history, however has proved that information is one of the most effective measures against the spread of drugs. The wide range of drug circulation and the need for the spread of correct information on the effects of drugs in man, especially his brain, have led the Center for Scientific Culture Diffusion of Cassino University, to widen the scope of "Alter Ego. Drugs and the brain", a touring educational exhibition, which opened in 1994, by dedicating more attention to socially accepted drugs, such as alcohol and tobacco, and to new substances like ecstasy and similar drugs. Concurrently with the Alter Ego touring exhibition, a study was undertaken to obtain information on public awareness of the dangers of psychotropic drug abuse and to assess the effectiveness of the exhibition as an instrument of scientific information about drug addiction among its visitors, during its tour of over 60 Italian towns.

Epidemiology of hepatitis C virus antibodies in blood donors from the province of Latina, Italy.

In order to calculate the incidence of hepatitis C virus (HCV) antibodies in blood donors and to verify the efficacy of the pre-donation method (testing blood samples of potential donors at least 3 months in advance of their first donation), we performed a retrospective cohort study in 1995 and in the period 1996-2000 at the blood transfusion unit in Latina (Italy). Third generation ELISA method as well as RIBA-3 were used. 5,978 donors in 1995 and 20,741 in the 1996-2000 period were analysed. The age of donors (prevalently male, 78.5%) was between 18 and 65 (median 38). A total of 110 borderline and 62 positives were found with ELISA, of which 75 borderlines and 42 positives in 1995, and the remaining in the 1996-2000 period (p > 0.5). Percentage of HCV antibodies dropped from 8.5% in 1995 to 5.45% in the 1996-2000 period. The non reactivity and undetermined status were found in 82.1 and 9.4% respectively in 1995, and 69.1 and 25.45% respectively in the 1996-2000 period. The incidence of HCV antibodies was 167.28 cases per 100,000 person-years in 1995 and 4.13 per 100,000 person-years in the 1996-2000 period, 2.5 times lower than the national one. There was a statistically significant association between dental care and RIBA positivity (RR: 2.63; p = 0.045). This study, moreover, evidences how pre-donation practices, if extended to a national basis, may be able to nullify the dangers associated with post-transfusional hepatitis and to reduce the number of false positives and of blood packs donated but either unused or destroyed.

[Knowledge, attitudes, and practices regarding sexually transmitted diseases among students in 3 high schools in Cassino]. / Conoscenze, attitudini e comportamenti riferiti in materia di malattie sessualmente trasmesse negli studenti di tre Istituti Superiori di Cassino.

In order to plan a health education programme in high schools in Southern Latium, a survey on knowledge, attitude and behaviour about Sexually Transmitted Diseases and AIDS was carried out among students of three high schools in Cassino. An anonymous, self-administered questionnaire was submitted to all students of the last two years in those schools. The results show a good knowledge of Cassino's students about HIV transmission, in similar or higher proportion respect to analogous surveys conducted in Italy or abroad. We found a good knowledge only about AIDS, Herpes genitalis and Syphilis, while knowledge about Hepatitis B, Condyloma acuminatum and Gonorrhoea is not satisfactory. Considering that 38% of male and 17% of female students declared to have already had their first sexual intercourse, the results suggest that there is a strong need to implement an educational intervention on sexuality and STD.

[Survey of the presence of bacterial pathogens in foods sold at retail stores in the city of Cassino]. / Indagine sulla presenza di batteri patogeni in alimenti venduti al dettaglio nella città di Cassino.

The presence of bacterial food pathogens was evaluated in 154 food samples collected from supermarkets and butchers in the city of Cassino (South-Central Italy). Food pathogens were identified in 17.5% of the total food samples. In the raw meat samples, 24.6% tested positives for Listeria monocytogenes, 4.3% for Salmonella and 2.9% for Escherichia coli O157. Y. enterocolitica, only investigated in pork meat, was identified in 7.4% of the samples. In poultry, L. monocytogenes was identified in 55% of the samples.

Overweight and Obesity among secondary school children in Central Italy.

Childhood and adolescent obesity prevalence rates have steadily increased in industrialised countries in the last 20 years. Current rates of obesity range between 6 and 30%. Several studies showed that risk factors for weight gain in school age are strongly linked to low physical activity and family environmental factors (parents' education and job, number of family members, number of hours spent on watching television, etc.). In order to plan a nutritional and health educational programme, a study was conducted on the nutritional status of the school age population of the Province of Frosinone, Central Italy, and family factors that can influence it. Three percentage of the school age population of the Province of Frosinone (2053 students) and their families were randomly sampled from the Province school district database. In each of the 12 recruited schools, a meeting with teachers and students was arranged to discuss aims and methods of research and to collect informed consent by students. Each student was interviewed about physical activity, and underwent the following measurements: height, weight, bicipital, tricipital, sub-scapular and over-iliacal skinfolds, sexual development. Students' parents were asked to answer a questionnaire about family structure, parents' educational level and job, parents' height and weight, presence in the family of pathologies as hypertension or diabetes. One thousand three hundred fifty-seven students (66% of the target population) and 1802 parents (66.5% of the responders' population) agreed to enter the study. Students' age range was 8 years (11-19 years; mean age was 14.9, SD, 2.55). Among them 8.4% were considered obese, with a higher prevalence in male population (9.8%) as compared to female population (6.5%). Of these responders, 21.4% were considered at risk of overweight with no statistical difference due to gender. Statistically significant correlations of teenagers' risk of overweight and obesity with nutritional conditions of parents, mother's educational level and amount of weekly physical activity were observed. Number of children in the family, parents' age and job do not appear to be correlated to obesity or risk of overweight. Our results show that, although the prevalence of obesity in the students population in the Province of Frosinone is comparable to other Italian Provinces and lower than other industrialised countries such as USA, the percentage of students at risk of overweight is particularly high. Main risk factors for developing obesity seem to be linked to parents' nutritional conditions, mother's educational level and children's physical inactivity and this should lead to intensify efforts for preventive interventions both at family level (focused on parents) and at school.

Breast and cervical cancer screening: knowledge, attitudes and behavior among schoolteachers in Italy.

The study explores knowledge, attitudes and behavior regarding screening for breast and cervical cancers. All female teachers in primary and secondary schools in Crotone and in Cassino (Italy) received a questionnaire on demographic and socioeconomic characteristics, clinical history, knowledge, behavior and attitudes about breast and cervical cancer and related screening procedures. A response rate of 65% was achieved. Knowledge on effectiveness of mammography and pap test in finding related cancers was widely spread in the sample. Only about 30% and 50% had respectively undergone their last mammogram and pap test according to the recommended time interval. Having been examined by a physician in the previous year and having had a screening CBE or a screening pap smear in the past three years were significantly more likely in women who underwent mammography for screening purposes in the past two years. Pap smear in the previous three years was significantly more likely in women in their forties, with a higher family income and in those who had been examined by a physician in the previous year. The results strongly recommend continued emphasis of physicians on education of women regarding mammography and pap smear.

Mothers and vaccination: knowledge, attitudes, and behaviour in Italy.

The study evaluates knowledge, attitudes, and behaviour of mothers regarding the immunization of 841 infants who attended public kindergarten in Cassino and Crotone, Italy. Overall, 57.8% of mothers were aware about all four mandatory vaccinations for infants (poliomyelitis, tetanus, diphtheria, hepatitis B). The results of a multiple logistic regression analysis showed that this knowledge was significantly greater among mothers with a higher education level and among those who were older at the time of the child's birth. Respondents' attitudes towards the utility of vaccinations for preventing infectious diseases were very favourable. Almost all children (94.4%) were vaccinated with all three doses of diphtheria-tetanus (DT), oral poliovirus vaccine (OPV), and hepatitis B. The proportion of children vaccinated who received all three doses of OPV, DT or diphtheria-tetanus-pertussis (DTP), and hepatitis B vaccines within 1 month of becoming age-eligible ranged from 56.6% for the third dose of hepatitis B to 95.7% for the first dose of OPV. Results of the regression analysis performed on the responses of mothers who had adhered to the schedule for all mandatory vaccinations indicated that birth order significantly predicted vaccination nonadherence, since children who had at least one older sibling in the household were significantly less likely to be age-appropriately vaccinated. The coverage for the optional vaccines was only 22.5% and 31% for measles-mumps-rubella and for all three doses against pertussis, respectively. Education programmes promoting paediatric immunization, accessibility, and follow-up should be targeted to the entire population.

[A clinical case of pulmonary thromboembolism in a patient at risk treated with rt-pA]. / Su di un caso clinico di TEP in un paziente a rischio trattato con rt-pA.

After a brief mention of new advances in the pathophysiology of fibrinolysis, the authors outline the pharmacological properties of the new thrombolytic agent rt-pA versus classic thrombolytic agent urokinase and streptokinase. Thereafter they report a case of acute pulmonary embolism with severe hypoxemia in a patient with a history of recent traumatic cerebral bleeding. Thrombolytic treatment with rt-pA (100 mg/2 h) resulted in a satisfactory clinical outcome without appreciable worsening of intracranial injury.
