 Tuberculosis


Overview

What is TB?

Tuberculosis (TB) is a disease caused by bacteria that are spread from person to person through the air. TB usually attacks the

lungs, but it can also attack and damage any part of the body, such as the brain, kidneys, or spine. A person with TB can die

without treatment. 

Symptoms

Latent TB: A person with latent TB will have no symptoms, and no damage will show on a chest X-ray. However, a blood test or skin prick test will indicate that they have TB infection.

Active TB: An individual with TB disease may experience a cough that produces phlegm, fatigue, a fever, chills, and a loss of appetite and weight. Symptoms typically worsen over time, but they can also spontaneously go away and return.

Early warning signs

A person should see a doctor if they experienceTrusted Source:

a persistent cough, lasting at least 3 weeks

phlegm, which may have blood in it, when they cough

a loss of appetite and weight

a general feeling of fatigue and being unwell

swelling in the neck

a fever

night sweats

chest pain

Beyond the lungs

TB usually affects the lungs, though symptoms can develop in other parts of the body. This is more common in people with weakened immune systems.

Causes

M. tuberculosis bacteria cause TB. They can spread through the air in droplets when a person with pulmonary TB coughs, sneezes, spits, laughs, or talks.

Only people with active TB can transmit the infection. However, most individuals with the disease can no longer transmit the bacteria after receiving appropriate treatment for at least 2 weeks.

TB can cause:

persistently swollen lymph nodes, or “swollen glands”

abdominal pain

joint or bone pain

confusion

a persistent headache

seizures

Diagnosis

A person with latent TB will have no symptoms, but the infection can show up on tests. People should ask for a TB test if they:

have spent time with someone who has or is at risk of TB

have spent time in a country with high rates of TB

work in an environment where TB may be present

A doctor will ask about any symptoms and the person’s medical history. They will also perform a physical examination, which involves listening to the lungs and checking for swelling in the lymph nodes.

Two tests can show whether TB bacteria are present:

the TB skin test

the TB blood test

However, these cannot indicate whether TB is active or latent. To test for active TB disease, the doctor may recommend a sputum test and a chest X-ray.

Everyone with TB needs treatment, regardless of whether the infection is active or latent.

Treatment

With early detection and appropriate antibiotics, TB is treatable.

The right type of antibiotic and length of treatment will depend on:

the person’s age and overall health

whether they have latent or active TB

the location of the infection

whether the strain of TB is drug resistant

Treatment for latent TB can vary.Trusted Source It may involve someone taking an antibiotic once a week for 12 weeks or every day for 9 months.

Treatment for active TB may involve taking several drugs for 6–9 monthsTrusted Source. When a person has a drug-resistant strain of TB, the treatment will be more complex.

It is essential for people to complete the full course of treatment, even if symptoms go away. If a person stops taking their medication early, some bacteria can survive and become resistant to antibiotics. In this case, the person may go on to develop drug-resistant TB.

TYPE OF DOCTOR AND DEPARTMENT: Infectious Diseases  SPECIALIST CAN DIGNOSES THIS DISEASE.

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

Dehydration Due to Diarrheal Diseases

Overview Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults. The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration. This means that even minor illnesses, such as infections affecting the lungs or bladder, can result in dehydration in older adults. Dehydration also can occur in any age group if you don't drink enough water during hot weather — especially if you are exercising vigorously. You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. ...

Vogt-Koyanagi-Harada (VKH) Disease

  Vogt-Koyanagi-Harada (VKH) Disease Disease Overview Vogt-Koyanagi-Harada disease is a rare disorder of unknown origin that affects many body systems, including as the eyes, ears, skin, and the covering of the brain and spinal cord (the meninges). The most noticeable symptom is a rapid loss of vision. There may also be neurological signs such as severe headache, vertigo, nausea, and drowsiness. Loss of hearing, and loss of hair (alopecia) and skin color may occur along, with whitening (loss of pigmentation) of the hair and eyelashes (poliosis). Signs & Symptoms Vogt-Koyanagi-Harada disease is initially characterized by headaches, very deep pain in the eyes, dizziness (vertigo), and nausea. These symptoms are usually followed in a few weeks by eye inflammation (uveitis) and blurring of vision. This may occur in both eyes at the same time or in one eye first and, a few days later, in the other. The retina may detach and hearing loss may become apparent. The chronic stage follows...
