HEARING LOSS

HEARING LOSS

It's difficult to hear or understand sounds if you have hearing loss. This occurs when one or more parts of the ear, the nerves that run from the ears, or the brain's hearing center malfunction.


Hearing loss is a condition that some people are born with. Hearing loss, on the other hand, may develop gradually over time or appear later in life. Hearing loss can run in families or be caused by birth defects, infections, or ear-damaging medications.

These types of hearing loss are unavoidable. Noise-induced hearing loss, on the other hand, is preventable. People who work in noisy environments, such as construction sites, road crews, and factories, may lose their hearing over time if they are not properly protected.


A decibel is a unit of measurement for sound levels that is commonly used in communication, signaling, and electronics. The decibel levels of some common noises are as follows:


Normal conversation levels – 60-65dB

Street traffic – 75-85dB

Motorcycles – 100 dB

Rock concerts and ambulance sirens – 120dB

Fireworks – 140-160dB

Sound from a movie theatre during action scenes – 100dB

Digital music is blasting from the speakers.– 112dB

Car horns and nightclub music – 110Db

Forklift and similar heavy machinery – 85dB

Heavy traffic or a lawnmower

From about 25 feet away, a tractor-trailer truck– 95-100dB

Chainsaw – 115-120dB


Hearing loss can show up in several ways, including:

Muffling of speech and other sounds


Requesting that others speak more slowly, clearly, and loudly regularly


Rising the television or radio volume


Withdrawal from conversations

Avoidance of some social settings


Having trouble understanding words, especially when there is background noise or when there are a lot of people around

Having trouble hearing consonants


Individuals who frequently listen to loud music with headphones while attending open-air music festivals or nightclubs, on the other hand, may be affected.


Many adults eventually notice that they're pressing the "volume up" button on the TV remote more frequently, or that a large number of people in their immediate vicinity need to speak up. While there are numerous hearing loss myths, there are two main reasons why people begin to lose their hearing:


Age: As you get older, your inner ear's tiny hair cells break down and can no longer pick up sound vibrations as well as they once could.


Noise: Exposure to a lot of loud noise for an extended period can harm the hair cells in your ears.


Damage to Hair Cells: When there is noise, hair cells bend in the same way that tall grass bends in the breeze. The more they flex, the more damage they cause to your hearing. The cells may straighten after a recovery period, but if they are too damaged, they will begin to die. In the average person's inner ear, there are approximately 16,000 hair cells. If a hearing test reveals that you have hearing loss, 30 to 50 percent of these cells have likely been damaged. This type of damage is frequently caused by noise and is This type of damage is frequently caused by noise and is usually irreversible.


Damage to the Ear Nerves: When sound vibrations strike the eardrum, the acoustic nerve, also known as the auditory nerve, transmits sound information from the inner ear to the brain. They effectively transmit sound when they work together with the middle and outer ear. Minor damage may not show up on a hearing test, but you may notice that hearing and understanding the person next to you in a noisy restaurant or crowd is becoming increasingly difficult.

Too Much Noise: Being bombarded with loud noises for an extended period can cause hearing damage. It can also happen if you're near loud, short bursts of noise, such as fireworks or gunshots. Avoiding loud noises as much as possible is the best way to avoid hearing loss.


Most types of hearing loss are irreversible. You can, however, improve your hearing by working with your physician or a hearing specialist.

All you need to know about Syphilis
All you need to know about Syphilis
ETIOLOGY: Syphilis is caused by T. pallidum.INCIDENCE: Each year, there are 29,000 new cases of syphilis. This figure represents probably only 10% of actual cases.CLINICAL FEATURES1. Primary syphilis: After an average incubation period of approximately 3 weeks, a smooth, painless ulcer called a chancre appears at the site of primary inoculation. The chancre heals without treatment in approximately 3 to 6 weeks; at about the same time, a painless uni- or bilateral regional adenopathy develops.2. Secondary syphilis represents disseminated disease and occurs in all patients with untreated primary infection. The lesions of secondary syphilis are papulosquamous lesions that occur over the entire trunk, extremities, penis, and buttocks. Fever and weight loss occur in 70% of patients.3. Tertiary syphilis occurs at least 10 years after the primary infection in at least 30% to 35% of untreated patients. The two most important manifestations of tertiary syphilis are cardiovascular syphilis, causing thoracic aneurysms, and neurosyphilis, causing meningitis, stroke, seizures, dementia, general weakness, and posterior column dysfunction.DIFFERENTIAL DIAGNOSES— Chancroid— HSV type 1 infection— Lymphogranuloma venereum— Tinea, sarcoid— Lichen planus— Seborrhea dermatitis— Molluscum contagiosum— Traumatic ulcer— Furuncle— CarcinomaEVALUATION: The clinical diagnosis can be confirmed by darkfield microscopic examination or more commonly serologic testing.THERAPY1. The standard treatment for primary, secondary, and early tertiary syphilis is benzathine penicillin G (2.4 million U administered intramuscularly as a single dose).2. For late tertiary syphilis or neurosyphilis, benzathine penicillin G (2.4 million U, three doses administered intramuscularly 1 week apart) is used. Doxycycline (100 mg orally twice daily for 14 days) can be given to patients who are allergic to penicillin.DISPOSITION1. Primary and secondary syphilis can be treated on an outpatient basis.2. Patients with neurosyphilis or major cardiovascular manifestations require admission for intravenous therapy.

What is Pemphigus Vulgaris?
What is Pemphigus Vulgaris?
Pemphigus Vulgaris is a rare disease that affects elderly patients. The mortality rate is 10%; most deaths result from steroid complications, secondary infection, dehydration, or thromboembolism. Pemphigus Vulgaris is caused by the attachment of immunoglobulin G autoantibodies to the epidermis. It has been associated with D -penicillamine and captopril administration.CLINICAL FEATURES1. Mucosal lesions and erosions are very common. Examination of all mucosal sites is warranted.2. Non-pruritic, painful, flaccid bullae appear that rupture easily. Blisters can be extended or new bullae formed by applying firm tangential pressure on the intact epidermis.3. Weakness, weight loss, and dysphagia may be presenting complaints.DIFFERENTIAL DIAGNOSES— Erythema multiforme— Bullous impetigo— Herpes zosterEVALUATION: Biopsy of lesions shows eosinophils, intraepidermal bullae, and acantholysis. Indirect immunofluorescent staining shows immunoglobulin G antibodies. Serum titers can be followed to evaluate the effectiveness of therapy.THERAPY1. Prednisone (200 to 350 mg/day) for 5 to 10 weeks is used until the cessation of new blister formation occurs. The dosage is then reduced to 40 mg on alternative days and tapered over 1 year.2. Azathioprine (100 mg/day) is added to the regimen and the dosage is reduced over a 4- to 6-month period. Methotrexate and cyclophosphamide can be used instead of azathioprine.3. Topical analgesics (e.g., viscous lidocaine) can be used to alleviate the pain associated with oral lesions.DISPOSITION: Patients with severe cases and oral lesions may require hospital admission for intravenous hydration. Others can be treated as outpatients with close follow-up.

Know about Scorpion Stings
Know about Scorpion Stings
Introduction: A nocturnal arachnid that lives in the Southwest of the United States is the scorpion. It has two venom glands and a stinger in its tail. The majority of species are rather benign, and they often only create a limited reaction similar to that brought on by a bee sting. The bark scorpion (Centruroides sculpturatus) venom, on the other hand, has neurotoxic that can result in a serious reaction. This dangerous scorpion is found on trees in Arizona and New Mexico.CLINICAL FEATURES1. Local effects: The C. sculpturatus scorpion bite causes immediate, excruciating pain at the stung site, as well as swelling and ultimately, numbness. The area that was hurt is extremely sensitive, and the implicated extremity could become paralyzed.2. Systemic effects: The neurotoxin is strongly cholinergic and can cause excessive salivation, blurred vision, muscular spasms, hypertension, and respiratory difficulties.DIFFERENTIAL DIAGNOSES — Snakebite— A puncture wound or other trauma— Insect or spider bite— Drug intoxicationEVALUATION: Typically, the offending scorpion is seen or assumed by history; if safety allows the scorpion to be brought in, this is best. Due to the wide range of symptoms and quick progression, a thorough history and physical examination are necessary.THERAPY1. Pre-hospital management includes rapid transportation of the patient, application of an ice pack to the sting site, and safe transport of the scorpion for identification. When serious symptoms appear, life-saving procedures should be started.2. ED managementa) Antivenin should be administered in all cases of severe envenomation.b) Ventilatory support may be required, with intubation and oxygen for patients with severe systemic response or anaphylaxis.c) Atropine may be required to counteract the cholinergic effects; the dose is titrated to relieve the cholinergic signs.d) Benzodiazepines may be used for seizures and muscle spasms.DISPOSITION: All victims should be observed for 24 hours, especially children. Symptomatic patients should be transferred to the intensive care unit if symptoms are severe.
