    Introduction. In Italy the number of teachers among private and public schools is around one million. Voice disorders are thought to be one of the major occupational hazards of school teaching; in fact the teachers often use their voice with high-intensity, in noisy classes, for a long time and without suitable breaks. The aim of the study was to assess the prevalence of voice problems in teachers of Naples district, identifying risk factors for develop- ing voice pathology. Methods. In this study we evaluated 504 teachers (322 F - 182 M) with an age ranging between 24 and 62 years, randomly choiced in 28 schools of the district of Naples submitted to a questionnaire to determine the prevalence of voice disorders. In our study we have also introduced a comparison group of not-teachers workers of 402 subjects (244 F - 158 M); they were in the same age range as the teacher sample (range: 22- 65 years). The control group was also submitted to a question- naire regarding sociodemographic characteristics, smoking and alcohol use, a self-report of voice problems, voice symptoms, frequency of acute and chronic voice problems, absenteism due to voice problems. Results. The prevalence of reporting a current voice problem was significantly greater in teachers compared with not-teachers (8.7% vs 2.9%), as the prevalence of voice disorders during their lifetime too (51.4% vs 25.9%), c2 = 86.672, p inf. 0.001. Women, compared with men had a higher lifetime prevalence of voice disorders. An other important data evidenced, is that 116 work- ers of the teachers group (23.01%) have been forced, during their professional activity, to miss job for problems related to voice; only 22 subjects of control group (5.47%) instead, missed job for voice troubles. Discussion and Conclusions. This study confirms that teachers have a higher rate of self-reported voice problems than subjects working in other occupations. Teachers, compared with not- teachers, were significantly more likely to have experienced multiple voice symptoms including hoarseness, discomfort while using their voice, difficulty projecting their voice and tiring or change in voice quality after short use. Large proportion of these problems may be preventable and prevention programs need to be developed and evaluated. Italian teachers do not receive any preventive voice training; that, in combination with poor hygienic work conditions, could increase health problems. Thus, voice training of teachers and teacher college students in some cases should be considered as a useful tool to prevent voice disorders

    Abstract Aim Aim of this study is to analyze the real movement, influenced by anatomical difficulties, of nickel-titanium rotary instruments within root canal systems; then the objective is to point out the physical and geometrical characteristics of an ideal instrument, able to overcome the most complex anatomies. Methodology At first, observation of the behavior of nickel-titanium rotary instruments within root canal systems and of the influence on them of root canal anatomy. Then, attempt to avoid the anatomical obstructions exploiting, with manual rotation, the advantages of a zero/low torque. Results Given that, in some root canals the severity of the curves prevents instruments to advance in rotation, we obtained significant results by manually advancing and rotating NiTi rotary instruments. Conclusions Therefore, in some cases, we would need an instrument that can reconcile efficiency with a reduction of mass and torque; the ideal instrument should have a very contained working part, combining efficiency with the decrease of mass and, consequently, of torsional stresses too

    Few studies analyzed the diffusion of vocal alterations especially in childhood. Aim of our study was to quantify the numbers of subjects, in paediatric age, in which dysphonia was diagnosed in our department of Phoniatrics, during a period of 5 years, (January 2002-December 2006), and also to evaluate the influence of some potential risk factors. In the considered period it emerged that the diagnosis of dysphonia was made in 312 children (17.2% of the patients affected from dysphonia), aged between 2 and 16 years old, with a major prevalence amongst males (57%) than females (43%). On the contrary in the adult population the prevalence was: 23% in males and 77% in females. In paediatric population, the most affected range of age is the one between 8 and 14, in both male and female gender (59.6%). In 82.4% of the cases there were vocal fold lesions. The 90.3% of children with vocal fold alterations presented lesions secondary to vocal abuse and misuse and classifiable as functional dysphonia. The proportion of functional dysphonia in our sample was 92%. The 65% of children belonged to large families with more than two children, and the 30% had a family history of dysphonia (brothers, parents). The study of the behavioural characteristics has shown aggressive and hyperactive attitudes in 83% of the cases. Since in the ethiopathogenesis of the childhood dysphonia the tendency to vocal abuse has a predominant role, it would be useful to encourage the diffusion of programmes of information to show the risks linked to this abuse in children, in order to prevent the development of dysphonia in paediatric age

    Get PDF
    We asked Italian poultry workers about knowledge, attitudes, and practices regarding avian influenza. It was perceived to be a low occupational hazard, and wearing protective equipment and handwashing were not routine practices. Knowledge of transmission and preventive measures should be improved. Employers and health professionals should provide more effective information

    <p>Abstract</p> <p>Background</p> <p>Crowding in hospital Emergency Departments (EDs) is a problem in several countries. We evaluated the number and characteristics of patients who make repeated visits to the EDs in Naples, Italy.</p> <p>Methods</p> <p>All patients (≥ 16 years) who presented to the EDs of three randomly selected non-academic acute care public hospitals, within randomly selected week periods, were studied. The two outcomes of interest were the re-utilization, within 72 hours, of the ED and the number of visits in the previous year.</p> <p>Results</p> <p>Of the 1430 sampled patients, 51.9% self-reported multiple visits in the previous year and 10.9% and 1.6% used the ED for 3 and ≥4 times, respectively. The number of visits in the previous year was significantly higher in those who live closer to hospital, with a more severe burden of overall comorbidity, and who were on pharmacological treatment. Overall, 72-hours return visits were found in 215 patients (15.8%). Patients were more likely to re-use within 72 hours the ED if younger, were not on pharmacological treatment, attended the ED more times in the previous year, were referred by a physician, arrived at the ED by car driven by other person, had problems of longer duration prior to arrival at the ED, had a surgical ED discharge diagnosis, and were admitted to the hospital.</p> <p>Conclusion</p> <p>The data may assist policymakers in the development and implementation of protocols to track changes in the re-utilization of the ED for the high financial impact and for the benefit of the patients.</p

    BACKGROUND: Pediatricians are in an ideal position to advise families about the prevention and management of oral diseases in children. The objective of the study was to determine knowledge, attitude, and practices regarding the prevention of oral diseases among pediatricians in Italy. METHODS: A systematic random sample of 1000 pediatricians received a questionnaire on socio-demographic and practice characteristics; knowledge on risk factors; attitude and practices towards the prevention of oral diseases. RESULTS: A total of 507 pediatricians participated. More than half knew the main risk factors for oral diseases and this knowledge was higher in primary care pediatricians (p = 0.007), in those with a higher number of hours worked per week (p = 0.012), and who believed that oral diseases may be prevented (p = 0.017). Pediatricians with higher knowledge about the main risk factors (p = 0.006) believe that they have an important role in preventing oral diseases and that they can perform an oral examination. Almost all (89%) prescribed fluoride supplements and those younger (p = 0.016), with a higher number of patients seen in workday (p = 0.001), with longer practice activity (p = 0.004), those who believe that fluoride is effective in preventing caries (p < 0.0001), and who learned about prevention from scientific sources (p = 0.002) were more likely to prescribe fluoride. One-fourth and 40.6% provides and recommends a dental visit once a year and primary care pediatricians (p = 0.014) and those who believed that routine visit is important in preventing oral diseases (p < 0.0001) were more likely to recommend a dental visit once a year. CONCLUSION: The results showed a lack of knowledge among pediatricians although almost all believed that they had an important responsibility in preventing oral diseases and provided an oral examination

    <p>Abstract</p> <p>Background</p> <p>Several public health strategic interventions are required for effective prevention and control of avian influenza (AI) and it is necessary to create a communication plan to keep families adequately informed on how to avoid or reduce exposure. This investigation determined the knowledge, attitudes, and behaviors relating to AI among an adult population in Italy.</p> <p>Methods</p> <p>From December 2005 to February 2006 a random sample of 1020 adults received a questionnaire about socio-demographic characteristics, knowledge of transmission and prevention about AI, attitudes towards AI, behaviors regarding use of preventive measures and food-handling practices, and sources of information about AI.</p> <p>Results</p> <p>A response rate of 67% was achieved. Those in higher socioeconomic classes were more likely to identify the modes of transmission and the animals' vehicles for AI. Those older, who knew the modes of transmission and the animals' vehicles for AI, and who still need information, were more likely to know that washing hands soap before and after touching raw poultry meat and using gloves is recommended to avoid spreading of AI through food. The risk of being infected was significantly higher in those from lower socioeconomic classes, if they did not know the definition of AI, if they knew that AI could be transmitted by eating and touching raw eggs and poultry foods, and if they did not need information. Compliance with the hygienic practices during handling of raw poultry meat was more likely in those who perceived to be at higher risk, who knew the hygienic practices, who knew the modes of transmission and the animals' vehicles for AI, and who received information from health professionals and scientific journals.</p> <p>Conclusion</p> <p>Respondents demonstrate no detailed understanding of AI, a greater perceived risk, and a lower compliance with precautions behaviors and health educational strategies are strongly needed.</p

    <p>Abstract</p> <p>Background</p> <p>Colorectal cancer (CRC) is the second most commonly diagnosed cancer for both sexes in developed countries. This study assessed the knowledge, attitudes, and preventive practices regarding CRC of adults in Italy.</p> <p>Methods</p> <p>A random sample of 1165 adults received a self-administered questionnaire on socio-demographic characteristics; knowledge regarding definition, risk factors, and screening; attitudes regarding perceived risk of contracting CRC and utility of screening tests; health-related behaviors and health care use; source of information.</p> <p>Results</p> <p>Only 18.5% knew the two main modifiable risk factors (low physical activity, high caloric intake from fat) and this knowledge was significantly associated with higher educational level, performing physical activity, modification of dietary habits and physical activity for fear of contracting CRC, and lower risk perception of contracting CRC. Half of respondents identified fecal occult blood testing (FOBT) as main test for CRC prevention and were more knowledgeable those unmarried, more educated, who knew the main risk factors of CRC, and have received advice by physician of performing FOBT. Personal opinion that screening is useful for CRC prevention was high with a mean score of 8.3 and it was predicted by respondents' lower education, beliefs that CRC can be prevented, higher personal perceived risk of contracting CRC, and information received by physician about CRC. An appropriate behavior of performing FOBT if eligible or not performing if not eligible was significantly higher in female, younger, more educated, in those who have been recommended by physician for undergo or not undergo FOBT, and who have not personal history of precancerous lesions and familial history of precancerous lesions or CRC.</p> <p>Conclusion</p> <p>Linkages between health care and educational systems are needed to improve the levels of knowledge and to raise CRC screening adherence.</p
