ABSTRACT

Objective: To explore the association between occupational noise exposure and cardiovascular disease (CVD) risk in a large Chinese population. Methods: In December 2019, the study included 21412 retired participants from the Dongfeng-Tongji Cohort Study at baseline from September 2008 to June 2010, occupational noise exposure was evaluated through workplace noise level and/or the job titles. In a subsample of 8931 subjects, bilateral hearing loss was defined as a pure-tone mean of 25 dB or higher at 0.5, 1 , 2, and 4 kHz in both ears. Logistic regression models were used to explore the association of occupational noise exposure, bilateral hearing loss with 10-year CVD risk. Results: Compared with participants without occupational noise exposure, the 10-year CVD risk was significantly higher for noise exposure duration ≥20 years (OR=1.20, 95%CI:1.01-1.41 , P=0.001) after adjusting for potential confounders. In the sex-specific analysis, the association was only statistically significant in males (OR=2.34, 95%CI: 1.18-4.66, P<0.001) , but not in females (OR=1.15, 95%CI:0.97-1.37, P=0.153). In the subsample analyses, bilateral hearing loss, which was an indicator for exposure to loud noise, was also associated with a higher risk of 10-year CVD (OR= 1.17, 95% CI:1.05-1.44, P <0.001) , especially for participants who were males (OR =1.24, 95% CI:1.07-2.30, P<0.001) , aged equal and over 60 years old (OR=2.30, 95%CI: 1.84-2.88, P<0.001) , and exposed to occupational noise (OR=1.66, 95%CI: 1.02-2.70, P=0.001). Conclusion: Occupational noise exposure may be a risk factor for CVD.

ABSTRACT

Streptococcus suis infection is an emerging zoonosis in Asia. The most common disease manifestation is meningitis, which is often associated with hearing loss and cochleovestibular signs. S. suis infection in humans mainly occurs among risk groups that have frequent exposure to pigs or raw pork. Here, we report a case of S. suis meningitis in a 67-yr-old pig carcass handler, who presented with dizziness and sensorineural hearing loss followed by headaches. Gram-positive diplococci were isolated from cerebrospinal fluid (CSF) and blood cultures and showed gray-white colonies with alpha-hemolysis. S. suis was identified from CSF and blood cultures by using a Vitek 2 system (bioMerieux, France), API 20 STREP (bioMerieux), and performing 16S rRNA and tuf gene sequencing. Even after receiving antibiotic treatment, patients with S. suis infection frequently show complications such as hearing impairment and vestibular dysfunction. To the best of our knowledge, this is the first case of S. suis meningitis in Korea. Prevention through public health surveillance is recommended, especially for individuals who have occupational exposures to swine and raw pork.

ABSTRACT

Son bien conocidos los efectos perjudiciales que un déficit auditivo produce en el desarrollo de niños afectados de tal patología, sobre todo en lo que hace a su vida de relación, comunicación, aprendizaje y escolaridad. Estos hechos motivaron a los diferentes grupos, vinculados con esta problemática, a unir esfuerzos; método y tecnología para detectar en forma precoz un déficit auditivo y procurar una temprana y efectiva rehabilitación. Cabe destacar que el período crítico para el desarrollo del lenguaje, ocurre durante los primeros 2 años de vida. El presente trabajo muestra los resultados, obtenidos durante el desarrollo de un programa de investigación multicéntrico-multidisciplinario, regional, tendiente a detectar precozmente esta patología. En el desarrollo del mismo participaron servicios públicos y privados de neonatología, unidades para cuidado intensivo de neonatos, servicios de otorrinolaringología infantil, etc. La selección de los pacientes fue realizada en base a un Registro de Alto Riesgo (RAR). Los pacientes incluídos fueron evaluados con examen ORL, pruebas auditivas de comportamiento, potenciales evocados auditivos de tronco cerebral (PEAT) y Audiometría por Respuestas Eléctricas (ARE). Se realizó un seguimiento longitudinal a los 1, 3, 6, 12 y 18 meses de edad, en aquellos casos en los cuales su patología lo justificara. Se describen los resultados obtenidos en 91 niños, cuya edad osciló entre los 17 días y 18 meses de nacidos, afectados de enfermedades tales como: hipoxia, meningitis, disgenesias, prematurez, etc. El PEAT fue anormal en el 57,14 por ciento, detectándose 8/91 hipoacusias profundas bilaterales.

ABSTRACT

Se presenta una familia cubana con 5 miembros afectados por una hipoacusia bilateral, congénita, severa, mixta con componente neurosensorial predominante y sin alteraciones morfológicas de oído interno. El patrón de transmisión era compatible con la herencia recesiva ligada al cromosoma X. Los estudios moleculares detectaron una deleción en la región Xq21.1 que implica el gen POU3F4, responsable de la sordera de tipo DFN3. Se hacen comentarios sobre la evidente variabilidad clínica de las sorderas tipo DFN3
