RESUMOObjetivo: descrever o conhecimento do conceito de agentes biológicos e equipamentos de proteção por profissionais de saúde em ambiente hospitalar, bem como a utilização dos equipamentos de proteção individual e coletiva. Método: estudo transversal e exploratório, com aplicação de questionário a 67 profissionais de saúde de um hospital, em Teresina-PI. Resultados: 84,5%, 95,4% e 79,2% dos profissionais de saúde autodeclararam o conhecimento dos conceitos de agentes biológicos, equipamentos de proteção individual e coletiva, respectivamente. No que diz respeito a utilização dos equipamentos de proteção individual, os mais citados foram luvas (32,1%), jaleco (29,2%) e máscara (28,1%). Já os de proteção coletiva, a caixa de perfurocortante (63,7%) foi a mais citada, seguida das pias de lavagem (58,6%) e autoclaves (20,8%). Conclusão: recomenda-se o incentivo para estratégias de educação continuada, para ampliar os impactos da biossegurança e de medidas preventivas para a segurança de todos os envolvidos em ambiente hospitalar.

ABSTRACTObjective: to describe the knowledge of the concept of biological agents and protective equipment by health professionals in the hospital environment, as well as the use of individual and collective protection equipment. Method: cross-sectional and exploratory study, with questionnaire application to 67 health professionals from a hospital in Teresina-PI. Results: 84.5%, 95.4% and 79.2% of health professionals self-declared knowledge of the concepts of biological agents, personal and collective protection equipment, respectively. Regarding the use of personal protective equipment, the most cited were gloves (32.1%), lab coat (29.2%) and mask (28.1%). As for the collective protection, the sharps box (63.7%) was the most cited, followed by washing sinks (58.6%) and autoclaves (20.8%). Conclusion: it is recommended to encourage continuing education strategies to increase the impact of biosafety and preventive measures for the safety of all those involved in the hospital environment.
Charcot–Marie–Tooth's disease (CMT) represents the most common inherited neuropathy. Most patients are diagnosed during late stages of disease course during adulthood. We performed a review of clinical, neurophysiological, and genetic diagnoses of 32 patients with genetically defined childhood-onset demyelinating CMT under clinical follow-up in a Brazilian Center for Neuromuscular Diseases from January 2015 to December 2019. The current mean age was 33.1 ± 18.3 years (ranging from 7 to 71 years) and mean age at defined genetic diagnosis was 36.1 ± 18.3 years. The mean age at onset was 6.1 ± 4.4 years. The most common initial complaint was bilateral pes cavus. The genetic basis included PMP22 duplication (CMT1A) (n = 18), GJB1 (CMTX1) (n = 5), MPZ (CMT1B) (n = 3), FIG4 (CMT4J) (n = 3), SH3TC2 (CMT4C) (n = 1), PLEKHG5 (CMTRIC) (n = 1), and PRX (CMT4F) (n = 1). Almost all patients (n = 31) presented with moderate or severe compromise in the CMT neuropathy score 2 with the highest values observed in CMT1B. Medical history disclosed obstructive sleep apnea (n = 5), aseptic meningitis (n = 1/MPZ), akinetic-rigid parkinsonism (n = 1/FIG4), and overlapping chronic inflammatory demyelinating polyneuropathy (n = 1/MPZ). Motor conduction block was detected in three individuals (PMP22, FIG4, MPZ). Acute denervation occurred in seven patients. Nonuniform demyelinating patterns were seen in four individuals (two CMT1A, one CMT1B, and one CMTX1). Abnormal cerebral white matter findings were detected in CMT1A and CMTX1, while hypertrophic roots were seen in CMT1A, CMT1B, and CMTX1. Our study emphasizes a relative oligogenic basis in childhood-onset demyelinating CMT and atypical findings may be observed especially in MPZ, PMP22, and GJB1 gene variants.
Objective: describe the profile of occupational accidents among doctors and nurses. Methodology: exploratory, descriptive and quantitative study, conducted at a public teaching hospital in the city of Teresina, Piauí, with 67 health professionals. Data were obtained in the months from February to May 2011, through a form, and analyzed the program "Statistical Package for the Social Sciences", version 20.0. Results: It was found that 28 professionals reported injuries, being the most prevalent category of nursing technician. As to age, the most affected were between 41 and 50 years. Regarding frequency, 11 had suffered two accidents, only one 10 and 2 with three accidents, with a total of 34 accidents. Peripheral venous puncture was practicing more involved in accidents, being mentioned by 16 of the 28 victims. 47 participants cited the Internal Commission for Accident Prevention as a place you should report the accident. Conclusion: verifies the need for continuing education courses on the use of containment barriers and accident prevention to minimize risk and ensure the safety of workers. Keywords: Occupational diseases. Occupational risks. Health personnel.
