Hearing damage caused by noise

Introduction: Noise is most common profession risk, as well as risk from environment, for hearing loss. Top limit for industrial noise is 85 dB. Objectives: Aim of our study was to determined all number of recognized professional diseases in our country, as well as to see which of industries are with highest prevalence of professional hearing damage caused by noise. Materials and method: We use an cohort study for analyzing patient histories which were hospitalized in the Institute of occupational health. All of them have recognized professional disease hearing loss. In order to be recognized as cases of a professional hearing damage, all of them had to satisfy all legal requirements. Results: Average age of patients with professional damage of cochlear nerve was 50 y. They have high total time period as well as exposed time period. In 2003. and 2004.,. there was highest number of detected and recognized cases of such professional diseases. More than half of examined patients had lesion between 30 and 40 percent following tables of F. S. Most of them were metal and mining industry workers. Conclusion: Following results of the study we can conclude that regular medical examinations of workers in all industries are necessary, specially in metal and mining industry. It is also needed to use personal protection items and to provide appropriate medical education of both workers and the management staff of said industries in order to prevent this kind of profession disease.

Abstract: Protecting and promoting the health of workers in the mining industry is one of the most important problems of occupational pathology and health care. The structure and levels of prevention of occupational diseases are directly dependent on harmful and adverse factors of the production environment and labor process, adequately reflecting the state of production. Purpose: to study the issues of prevention of occupational and production-related diseases of mining and metallurgical plant workers. Research materials and methods: a dynamic observation of the health status of workers in the main industries of the mining and metallurgical plant (800 workers) was carried out. 92 patients with silicosis were examined. Results: Up to 92.8% of first-time occupational diseases are detected during periodic medical examinations. The prevailing sociomatic pathology is cardiovascular pathology, namely, arterial hypertension and diseases of the musculoskeletal system, mainly osteochondrosis of the spine. Prevalence of silicosis was observed in individuals with little professional experience (from 5 years old), young age and primary detection of patients in stage II silicosis, which was accompanied by respiratory failure. Conclusions: The prevention programme developed will ensure a high level of health care in terms of early diagnosis, rehabilitation and secondary prevention of both occupational and occupational diseases.

Background: There is no available estimate of the incidence and mortality of epilepsy in all age groups in the Canadian population. This study aimed to measure the incidence, prevalence, mortality and the secular trends for epilepsy in Saskatchewan between 2005 and 2010. Methods: A population-based cohort study was established from Saskatchewan’s provincial health administrative data. The population was followed until termination of coverage, death, or 31 December 2010. Individuals with epilepsy were identified based on ICD codes algorithms from 2005 to 2010. Results: The age-standardized incidence of epilepsy was 62 per 100,000 person-year. The age-standardized incidence rate of epilepsy in self-declared Registered Indians was 122 per 100,000 person-year. There was a significant decrease in the incidence of epilepsy for all groups over the study period. The age-standardized prevalence of epilepsy was 9 per 1,000 people. There was a significant increase in the prevalence of epilepsy over this time period. The adjusted mortality rate was 0.023 per 1000 person-year, and the all-cause Standardized Mortality Ration for epilepsy was 2.45. The SMR remained constant over the six-year period of the study. Conclusions: This study is the first in Canada to measure the incidence and all-cause mortality of epilepsy in all age groups.

AbstractObjectiveTo describe patterns of anticogulation prescribing and persistence for those aged ≥65 years with atrial fibrillation (AF).MethodsDescriptive cohort study using electronic general practice records of patients in England who attended a flu vaccination aged ≥65, and were diagnosed with AF between 2008-2018. Patients were stratified by 10 year age group and year of diagnosis. Proportion anticoagulated, type of anticoagulation (direct oral anticoagulant (DOAC) or Warfarin) initiated at diagnosis, and persistence with anticoagulation over time are reported.Results42,290 patients (49% female), aged 65-74 (n=11,722), 75-84 (n=19,055) and 85+ (n=11,513) at AF diagnosis are included. Prescription of anticoagulation at diagnosis increased over the time period from 55% to 86% in people aged 65-74, from 54% to 86% in people aged 75-84 and from 27% to 75% in people aged 85 and over. No patients were prescribed DOACs as a first anticoagulation agent in 2008, by 201892% of new AF patients were started on DOACs. Survivor function for 5 year persistence for patients taking only a single type of anticoagulant was 0.80 (0.77:0.82) for DOACs and0.71(0.70:0.72) for warfarin, Survivor function for any anticoagulation at 5 years was0.79(0.78:0.81), 0.73(0.72:0.75), 0.58(0.59:0.64) for people aged 65-74, 75-84 and 85+ respectively.ConclusionsRates of anticoagulation for new AF in those aged ≥65 have increased from 2008 to 2018, over which time there has been a shift from initiating anticoaguation with warfarin to DOACs. Persistence with anticoagulation is higher in people on DOACs than on warfarin, and in people under the aged of 85.Key MessagesWhat is already known?Anticoagulation is a highly effective way of reducing the risk of stroke associated with AF, but is underused, particularly in older people. The introduction of DOACs has been associated with increasing use of anticoagulation in AF.What does this study add?Our study provides up to date information on anticoagulation for AF in older people who are most at risk of AF related stroke and highlights particular increases in use of anticoagulation in people aged 85 and over.DOACs are now the major class of anticoagulant prescribed to patients with new AF in UK general practice.Long term persistence with anticoagulation is higher with DOACs than warfarin, but drops in all age groups over 5 years.How might this impact on clinical practice?Improved uptake of anticoagulation at all ages removes one of the potential barriers to screening for atrial fibrillation, but new strategies may be needed to enhance longer term persistence with treatment.

Background: The aim of the study was to assess impact of duration of tympanic membrane perforation on hearing loss and postoperative audiological outcome using pure tone audiogram.Methods: The present study was conducted on 100 patients in department of ENT and HNS, SMGS Hospital, Government Medical College Jammu during a time period of November 2018 to October 2019. All the patients with age 15 to 60 years who presented with tympanic membrane (pars tensa) perforation were included in the study. Results: In our study, mean preoperative hearing loss (AC threshold) of group A was 36.23±1.07 dB and of group B was 25.67±6.38 dB. Group C had mean preoperative hearing loss (AC threshold) of 28.78±6.50 dB. Mean preoperative air-bone gap (AB gap) of group A was 12.9±8.05dB and of group B was 13.86±4.19 dB. Group C had mean preoperative air-bone gap (AB gap) of 16.47±5.51 dB. Postoperatively, pure tone threshold at three months was least in group B (15.09±5.80 dB), followed by group C (15.68±4.66 dB) and group A (19.33±2.81 dB). Whereas, postoperative AB gap at 3 months was least in group C (10±3 dB), followed by group C (8.44±3.59 dB). Group B had maximum postoperative AB gap of 8.49±4.34 dB.Conclusions: This study did not show any correlation between duration of disease and degree of hearing loss.

IntroductionThe mainstay of treatment for idiopathic sudden sensorineural hearing loss (SSNHL) includes oral steroids, intratympanic steroid injections or a combination of both. The National Institute for Health and Care Excellence, in their recent hearing loss guidelines, highlighted the paucity of evidence assessing the comparative effectiveness of these treatments; and the National Institute for Health Research (NIHR) Health Technology Assessment Programme has since released a commissioned call for a trial to identify the most effective route of administration of steroids as a first-line treatment for idiopathic SSNHL. For such trials to be run effectively, reliable information is needed on patients with SSNHL: where they present, numbers, demographics, treatment pathways, as well as outcomes. This study will collect these data in a nationwide cohort study of patients presenting with SSNHL across 97 National Health Service (NHS) trusts. The study will be delivered through ear, nose and throat (ENT) trainee networks, the NIHR Clinical Research Network (CRN) Audiology Champions and the NIHR CRN. Importantly, this study will also provide a dataset to develop a prognostic model to predict recovery for patients with idiopathic SSNHL. The study objectives are to: (1) map the patient pathway and identify the characteristics of adult patients presenting to NHS ENT and hearing services with SSNHL, (2) develop a prognostic model to predict recovery for patients with idiopathic SSNHL and (3) establish the impact of idiopathic SSNHL on patients’ quality of life (QoL).Methods and analysisStudy design: national multicentre prospective cohort study across 97 NHS trusts.Inclusion criteria: adult patients presenting to NHS ENT and hearing services with SSNHL.Outcomes: change in auditory function; change in QoL score.Analysis: multivariable prognostic model, using prespecified candidate predictors. Mean change in QoL scores will be calculated from initial presentation to follow-up.Ethics and disseminationHealth Research Authority and NHS Research Ethics Committee approved the study. Publication will be on behalf of study sites and collaborators.Trial registration numberClinicalTrials.gov Registry (NCT04108598).
