Prevalence of occupational voice disorders in teachers

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

Epidemiological study on vocal disorders in paediatric age

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

Knowledge, Attitudes, and Practices of Avian Influenza, Poultry Workers, Italy

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

Microbiological quality of drinking water from dispensers in Italy

<p>Abstract</p> <p>Background</p> <p>Water coolers are popular in office buildings and commercial stores and the quality of this source of drinking water has the potential to cause waterborne outbreaks, especially in sensitive and immunocompromised subjects. The aim of this study was to determine the quality of water plumbed in coolers from commercial stores in comparison with tap water in Italy.</p> <p>Methods</p> <p>For each sample, microbial parameters and chemical indicators of contamination were evaluated and information about the date of installation, time since last ordinary and extraordinary maintenance of water coolers was collected.</p> <p>Results</p> <p>In all samples the chemical parameters (nitrite, ammonium, free active chlorine residual) did not exceed the reference values of the drinking water regulation; the pH value in 86.8% samples of the carbonated waters was lower than the reference limit. The microbiological results indicated that the bacteria count at 22°C and 37°C was higher than the required values in 71% and 81% for the non-carbonated water and in 86% and 88% for the carbonated one, respectively. <it>Enterococcus </it>spp. and <it>Escherichia coli </it>were not detected in any of the water samples. <it>Pseudomonas aeruginosa </it>was found in only one sample of the tap water and in 28.9% and 23.7% of the non-carbonated and carbonated water samples, respectively. No statistically significant differences in bacterial counts at 22°C and 37°C have been found between the non-carbonated and carbonated water from the sampled coolers in relation with the time since the last filter was substituted. The bacteriological quality of tap water was superior to that of non-carbonated and carbonated water from coolers.</p> <p>Conclusion</p> <p>The results emphasize the importance of adopting appropriate routinely monitoring system in order to prevent or to diminish the chances of contamination of this water source.</p

Characteristics of patients returning to emergency departments in Naples, Italy

<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

Antibody levels after BNT162b2 vaccine booster and SARS-CoV-2 Omicron infection

In the present study, immunogenicity data in 61 vaccinated healthcare workers (HCWs) either infection naïve (naïve HCWs) or with infection of Delta and/or Omicron COVID-19 (experienced HCWs) were evaluated up to 270&nbsp;days after the second dose of BNT162b2 vaccine and up to 90&nbsp;days after a booster dose. A decrease in antibody levels at 270&nbsp;days following administration of the second dose (p&nbsp;=&nbsp;0.0335) was observed, although values did not fall below the positivity threshold (33.8 BAU/ml). After booster vaccination, antibody levels increased after 30&nbsp;days (p&nbsp;=&nbsp;0.0486), with much higher values than after first and second vaccination. Antibody levels then decreased at 60 and 90&nbsp;days after the booster dose. A comparison between mean antibody levels of naïve and experienced HCWs revealed higher values in experienced HCWs, resulting from both natural and vaccination-induced immunity. A total of 14.7% of HCWs contracted the Omicron virus variant after the vaccine booster, although none showed severe symptoms. These results support that a booster dose results in a marked increase in antibody response that subsequently decreases over time

A survey of knowledge, attitudes and practices towards avian influenza in an adult population of Italy

<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

Healthcare workers and health care-associated infections: knowledge, attitudes, and behavior in emergency departments in Italy

<p>Abstract</p> <p>Background</p> <p>This survey assessed knowledge, attitudes, and compliance regarding standard precautions about health care-associated infections (HAIs) and the associated determinants among healthcare workers (HCWs) in emergency departments in Italy.</p> <p>Methods</p> <p>An anonymous questionnaire, self-administered by all HCWs in eight randomly selected non-academic acute general public hospitals, comprised questions on demographic and occupational characteristics; knowledge about the risks of acquiring and/or transmitting HAIs from/to a patient and standard precautions; attitudes toward guidelines and risk perceived of acquiring a HAI; practice of standard precautions; and sources of information.</p> <p>Results</p> <p>HCWs who know the risk of acquiring Hepatitis C (HCV) and Human Immunodeficiency Virus (HIV) from a patient were in practice from less years, worked fewer hours per week, knew that a HCW can transmit HCV and HIV to a patient, knew that HCV and HIV infections can be serious, and have received information from educational courses and scientific journals. Those who know that gloves, mask, protective eyewear, and hands hygiene after removing gloves are control measures were nurses, provided care to fewer patients, knew that HCWs' hands are vehicle for transmission of nosocomial pathogens, did not know that a HCW can transmit HCV and HIV to a patient, and have received information from educational courses and scientific journals. Being a nurse, knowing that HCWs' hands are vehicle for transmission of nosocomial pathogens, obtaining information from educational courses and scientific journals, and needing information were associated with a higher perceived risk of acquiring a HAI. HCWs who often or always used gloves and performed hands hygiene measures after removing gloves were nurses, provided care to fewer patients, and knew that hands hygiene after removing gloves was a control measure.</p> <p>Conclusions</p> <p>HCWs have high knowledge, positive attitudes, but low compliance concerning standard precautions. Nurses had higher knowledge, perceived risk, and appropriate HAIs' control measures than physicians and HCWs answered correctly and used appropriately control measures if have received information from educational courses and scientific journals.</p

Knowledge, attitude and practices of pediatricians regarding the prevention of oral diseases in Italy

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
