There are three main types of hearing losses. They are conductive, sensorineural, and mixed. The type of hearing loss depends upon where in the ear the problem occurs. With conductive hearing loss there is a problem in the external or middle ear that prevents sound from reaching the nerves in the inner ear. External otitis; also known as swimmers ear can also be a cause of conductive hearing loss. Other causes include excessive cerumen or presence of a foreign body in the ear canal. Infections involving a hair follicle called furuncle or involving multiple hair follicles called carbuncle where an abscess may form can also be a cause. Benign masses may also be found in the external ear causing the ear to become red and inflamed. Your patient will be complaining of pain radiating inward on the affected side. Absence of or malformation of the outer ear, ear canal, or middle ear may also cause conductive hearing loss. Otitis media is the most common cause of hearing loss in the middle ear and usually follows an upper respiratory infection. The patient would be experiencing fever, earache and feeling of fullness in the affected ear. A perforated or ruptured tympanic membrane resulting from trauma or exposure to loud noise or repeated infections causing pressure on the membrane can also cause conductive hearing loss. The stapes in the middle ear can develop ostosclerosis preventing it from vibrating which will prevent sound from getting to the inner ear. This begins progressively mainly in women after the age of forty. If prompt medical or surgical treatments are done, permanent hearing loss may be avoided. Treatments for conductive hearing loss include removal of cerumen build up by irrigating the ear canal. If there is fluid trapped in the ear; procedures such as paracentesis using a needle or a myringtomy which makes an incisionis in the tympanic membrane will allow fluid to drain or be suctioned out of the middle ear. A surgery called a myringoplasty can also be done to repair a damaged tympanic membrane. A stapedectomy can also be done to remove a damaged stapes and replace it with prosthesis. Hearing aids are also another treatment commonly used to assist your patient with their hearing loss. Another type of hearing loss known as sensorineural hearing loss; also known as nerve hearing loss occurs in the inner part of the ear. The damaged nerves of the inner ear do not properly transmit the signals to the auditory centers of the brain. There are many causes, differing by age of onset. They can occur before or during birth from perinatal infections, heredity, and asphyxia at birth, low birth weight, or defects of the head and neck. Other causes can be from an infection or inflammation of the inner ear known as a labyrinthitis. This can also be caused by drug toxicity from some antibiotics, as well as some diuretics. Overindulgence of alcohol or some allergies have also been related to hearing loss. A couple of the most common signs of an inner ear infection are vertigo and tinnitus. Other symptoms include pain, fever, ataxia, nausea, and vomiting. The natural degeneration of the organ of Corti known as Presbycusis; or Neoplastic disorders such as inner ear tumors can also causes sensorineural hearing loss. Acoustic neuroma, a tumor of the eighth cranial nerve, is the most common benign tumor. Symptoms include unilateral loss of high pitched sounds, unilateral tinnitus as well as intermediate vertigo. Headache and balance disorders may also be present. A balance disorder called Meniere’s disease involves a group of symptoms including deafness, tinnitus, vertigo, and sensation of fullness or pressure in the ears. Acute episodes can last 2 to4 hours at a time. The symptoms will resolve after several weeks but the hearing loss in the affected ear remain and your patient will experience some degree of permanent hearing loss. Normal conversation levels occur at about 60 decibels. Prolonged exposure to loud noises above 90…
Hearing Paper: Otitis Media
University of Montana
Middle ear disease and middle ear infection are two of the many ways to refer to otitis media, an inflammation of the middle ear. Despite its many names, otitis media has only one primary cause, Eustachian (auditory) tube dysfunction. There are many risk factors that may prevent proper Eustachian tube function and which may ultimately result in a conductive hearing loss (Klein, 1994).
The Eustachian tube is described…
distortion of vision that makes straight lines look wavy, as well as blind spots and loss of central vision. They eventually scar, leading to permanent loss of central vision. They affect daily life in that there is struggle to do housework, studying, shopping, enjoying leisure activities and interests such as reading.

research based treatments for ASD
* Educational Programming for children w/Autism should include:
1) Direct instruction of skills
2) Behavior management using an FBA & PBS
3) Instruction in natural settings
* Since IDEA stipulates that interventions used w/children must be evidence-based (peer-reviewed), it is important that teachers are aware of current evidence-based practices
* National Autism Center (NAC) – report on evidence-based treatments, emerging treatments, and ineffective…
have some kind of hearing loss. These ten percent suffer from unfair treatment from professional, social and government service providers, including court and police”. Obviously, because deaf and hard of hearing have limited hearing, their communication and social skills are below a common hearing person. Therefore, most of these people are ignored, neglected, and discriminated against. However, a citizen protected by the American with Disabilities Act, deaf and hard of hearing people deserve equal…

Murphy Odone was only 5 years old when he was diagnosed with this leathal disease. It all began when his teachers started noticing weird rage outburst temper tantrums at school. Then he developed more strange symptoms such as hearing loss, not being able to stay balanced , and loss of vision. Its a rare disease that only boys ages 5-10 can have. Its passed down from their mothers but the mom could never get sick because its sex linked her second X chromosome protects her, all she can be is a carrier…
As a medical professional, there will be times when you are faced with patients who have difficulties such as visual impairment or hearing impairment. Both of these issues deem the person to be a part of a ‘marginalized’ population; however, this should lend any different form of medical treatment. It should, though, cause medical professionals to spend a bit more quality time in caring for these individuals.
A patient with visual impairment is not necessarily completely blind. Many patients still…

Walker’s memoir, written from a hearing person’s perspective, explores the dynamics between deaf and hearing culture and the unique role occupied by children of deaf parents, who move between deaf or hearing worlds, often feeling as though they…
with Klinefelter's syndrome should be treated with testosterone, usually at 11 or 12 years of age. Treatments could include Restandol tablets, which does not affect the liver, or with injections of other testosterone preparations.
Klinefelter boys more often than other boys have delayed motor function, speech, and maturation development, which does not make them patients demanding special treatment. If the speech development is delayed, it is important to get help from a speech-therapist for a…
