This document analyzes policies surrounding access to cochlear implants through insurance coverage. It discusses ambiguities in corporate policies and judicial rulings regarding distribution of resources. Hearing loss is increasing globally due to environmental factors and aging. While cochlear implants can help, the high cost poses barriers. Minorities tend to have less coverage and income to afford implants. The document calls for solutions to improve access by influencing costs and quality of care.
The effects of tuberculosis and hearing lossmphaliuj
1. Tuberculosis can spread to various organs in the body, including the ears. Research has shown a link between TB and decreased hearing thresholds. People with both TB and exposure to loud noises are at higher risk of hearing loss.
2. Patients being treated for multi-drug resistant TB with certain antibiotic drugs like aminoglycosides and capreomycin are at risk of permanent sensorineural hearing loss caused by the ototoxic effects of these drugs.
3. While HIV itself does not cause hearing loss, people with HIV aged 35 and older who take ototoxic antiretroviral drugs have a higher risk of developing sensorineural hearing loss. HIV can also increase the risk of middle ear disorders and

Tooth loss has been a long-accepted fact of aging. Almost 20 percent of American seniors do not have their natural teeth. Furthermore, the risk of losing the teeth increases as the person ages.
Most hearing loss is caused by genetic irregularities, with over 100 genes associated with hearing loss. Genetic hearing loss can affect the outer or inner ear, causing sensorineural, conductive, or mixed hearing loss. Some genetic conditions like Usher syndrome and Waardenburg syndrome cause hearing loss along with other symptoms. Genes related to hearing loss are usually recessive, so a child may have normal hearing if they receive a normal copy of the gene from one parent, even if both parents have hearing loss.
Introduction to Audiological and Balance assessmentsBrownYoungsters
This document provides information about conducting audiological and balance assessments. It discusses reading patient prescriptions and complaints, taking patient history, and performing various diagnostic tests. History taking involves understanding relevant medical information, symptoms, and lifestyle factors. Factors discussed that can affect hearing include genetics, infections, medications, noise exposure, and underlying medical conditions like diabetes or thyroid disorders. The document provides examples of history formats for infants, children, and adults. It explains how various conditions and exposures can impact hearing, such as low birth weight, infections, and ototoxic medications or substances.
Genetic factors are actually the main category of hearing losses. Additionally, hearing loss is considered the most common birth defect in the developed world.
Sounding off on hearing aids expert advice from the federal trade commissionRobin Hardin
The Federal Trade Commission recommends that the over 35 million Americans with impaired hearing seek advice from a qualified hearing specialist like an otolaryngologist, audiologist, or hearing aid dispenser when choosing a hearing device. An otolaryngologist is a disease specialist who does not typically fit hearing aids. Hearing aid dispensers' qualifications vary by state and they may or may not be hearing experts. An audiologist has a Masters degree and potentially a doctorate, can perform hearing tests and fit hearing aids, and provides expert hearing loss advice on beneficial accessories. The FTC advises trusting a qualified hearing specialist over a so-called expert for hearing loss help.

The document provides a list of questions for a patient to ask their hearing specialist before purchasing hearing aids. It covers four major topics: hearing loss, styles and features of hearing aids, financing options, and operation and care of hearing aids. Some example questions are what type of hearing loss does the patient have, which hearing aid style is best for their needs, what is the total cost including services, how to operate and care for the hearing aids, and how to schedule a hearing test. The document aims to help the patient create a comprehensive list of questions to ensure they get the right hearing solution.
This document exposes and debunks 5 common myths about hearing aids. Myth #1 is that hearing aids are not effective, but studies have shown they significantly improve speech recognition and reduce communication problems. Myth #2 is that hearing aids are big and bulky, but they now come in various small, nearly invisible sizes. Myth #3 is that hearing aids are too expensive, but like other electronics, prices vary with features and performance. Myth #4 is that hearing aids can be bought online more cheaply, but proper fitting requires professional programming. Myth #5 is that hearing aids are uncomfortable and hard to use, but digital aids are easy to use and control.

Nearly 12% of children ages 6-19 have noise-induced hearing loss. Approximately 12,000 babies are born with hearing loss each year in the United States. Hearing loss can delay language development if not addressed early on. Some causes of hearing loss in children, like ear infections, are temporary if treated promptly but can become permanent if ignored. Early identification and treatment of hearing loss leads to better language outcomes for children. Permanent noise-induced hearing loss can be prevented by using hearing protection for loud noises. Parents should monitor their children for signs of hearing loss.
Sensorineural hearing loss is caused by damage to the tiny nerve endings in the inner ear, reducing a person's ability to hear certain sounds clearly. It can be present from birth due to genetic factors or infections, or develop later in life due to acoustic trauma, viruses, tumors, changes in air pressure or head injuries. Symptoms include difficulty hearing in noisy environments or distinguishing between men's and women's voices. While it can decrease quality of life, treatment options and assistive devices are available to help manage sensorineural hearing loss.
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.
