“…During the period of data survey the hospital employees answered a questionnaire adapted from Fernandes and Morata 2002 11 and Siqueira 2012 12 (Appendix). The involved workers compose a group characterized as a multidisciplinary team as it involves health professionals and public service aids.…”

Purpose: to assess the noise level in different environments of a public hospital and to analyze its effects on employees from reporting complaints. Methods: a quantitative, descriptive and cross-sectioned study. To survey data, we used a Minipa® decibelimeter adjusted in the range 40-130 decibels positioned in different hospital departments in different shifts for a week to evaluate noise levels and an adapted questionnaire that was applied to employees. Results: the level of noise introduced minimum of 52.5 decibels in the Intensive Care Unit (NICU) and a maximum of 85 decibels in the women's ward with a significant difference between the different days of the week during the same turn. The same occurred in the emergency room, but did not show significance in other sectors. Employees feel discomfort to loud sounds, 74.4%, and 35.5% feel sick after hours due to stress caused by noise that is produced by multiple devices combined with the sounds of alarms, works, visits and schedules conversation between the hospital staff. Conclusion:noise levels are above the recommended levels in different sectors and professionals manifest discomfort and tinnitus before and after their exposure.

“…Mechanisms involved in the development of this disease are not fully understood yet, but it is known that exposure to high doses of noise causes decreased blood flow and formation of free radicals in the cochlea (Le Prell et al, 2007). According to Fernandes and Morata (2002), even using Individual Protection Equipment, tractor operators presented PAIR, in addition to extra-auditory effects such as nervousness, anxiety, headache, tinnitus and stomach problems.…”

Proposal for an Ergonomic Conformity Index for Evaluation of Harvesters and Forwarders

2017

-Context: In mechanized forestry work, the ergonomic conditions of the workplace affects operator's health, performance and productivity. Originality: A comparison of different forest machines becomes complex in case where it is required analysis of several ergonomic factors simultaneously. There are several methods of ergonomic analysis however, a more complete methodology that considers several ergonomic factors and produces an index that represent the ergonomic condition of the machine is needed. Objective: Propose a methodology to determining an Ergonomic Conformity Index to evaluate Harvesters and Forwarders of different brands. Methodology: The ECI was determined initially basing in four relevant ergonomic factors: noise, vibration, thermal environment and air quality. These factors were evaluated utilizing four Harvesters and two Forwarders in eucalyptus timber harvesting operations. For each factor, a score was given according to its compliance with the established parameters. The ECI was obtained from an average of the scores given to each factor. The index ranges from zero to one, so that lower values indicate worse ergonomic conditions. Results: All the analyzed machines had continuous noise between 75.0 and 82.6 dB (A) and whole-body vibration between 0.27 and 0.70 m s -2 . HV1 and HV2 presented thermal environment in accordance with the established criteria, other machines showed deficiencies in this regard. All the machines presented non-conformities in the air quality, except HV2. The ECI of Harvesters HV1, HV2, HV3 and HV4, were 0.83; 0.88; 0.71; 0.63. The ECI of Forwarders FW1 and FW2 were 0.58 and 0.79. Conclusion: The determination of the ECI allowed an evaluation and comparison between analyzed forest machines. The machine with the higher ECI had only one non-conformity, and it was related to noise inside the cab. The machine that got the lower ECI presented non-conformities for all the factors.

“…Hearing damage associated with aminoglycoside use can include permanent hearing loss and tinnitus secondary to the degradation of sensorineural hair cells of the cochlea and/ or vestibule. Damage to cochlear hair cells is thought to be mediated by oxidative stress, starting at the base where highfrequency sounds are decoded and advancing to the apex 6,8,13,14,15 .…”

Introduction: A total of 771 cases of multidrug-resistant tuberculosis (MDR-TB) were reported in Brazil in 2014. Treatment of MDR-TB with aminoglycosides can produce serious side effects such as permanent and irreversible hearing loss, which occurs in 5-64% of cases, and severely compromise patient quality of life. The goal of this research was to evaluate auditory and vestibular side effects in patients treated for MDR-TB and to identify associations between these complaints and the type of aminoglycoside used. Methods: We performed a retrospective review of 599 medical records from patients with MDR-TB who were treated at the Hélio Fraga/Fiocruz Reference Center between 2006 and 2010. Cases without auditory or vestibular complaints and patients who were not treated with aminoglycoside drugs were excluded from the study. Results: Of 164 eligible cases, 55 (33.5%) reported an auditory or vestibular complaint and medication was subsequently suspended, although hearing damage was not confirmed in all cases. Audiometric testing confirmed hearing loss in 11 (21.7%) of 12 cases submitted for evaluation. Hearing loss related to ototoxicity was confirmed in 15 (62.5%) cases. Tinnitus was significantly associated with the use of amikacin and streptomycin. Conclusions: Evaluations of ototoxicity symptoms were not usually reported in the routine care of patients with MDR-TB. Complaints of tinnitus were associated with amikacin and streptomycin use. These results require confirmation in future studies.
