654 Questions

Why are sputum cultures performed?

A sputum culture is done to find and identify the microorganism causing an infection of the lower respiratory. If a microorganism is found, more testing is done to determine which antibiotics will be effective in treating the infection.

What is tuberculosis meningitis?

a condition that is most common in young children but is especially dangerous in the elderly. Patients develop headaches, become drowsy, and eventually comatose. Permanent brain damage is the rule unless prompt treatment is given.

What happens when Mycobacterium tuberculosis infects humans?

Most patients never develop symptoms, but about 10% of infected people develop serious, prolonged lung disease.

What is reactivation tuberculosis?

One type of infection is called reactivation tuberculosis. Here, the primary infection has resolved, but the bacteria are dormant, or hibernating. When conditions become favorable (for instance, a lowered immunity), the bacteria become active. Tuberculosis in older children and adults may be of this type. The most prominent symptom is a persistent fever, with sweating during the night. Fatigue and weight loss may follow. If the disease progresses and cavities form in the lungs, the person may experience coughing and the production of saliva, mucus, or phlegm that may contain blood.

What happens when TB spreads to the joints?

Tubercular infection of joints causes a form of arthritis that most often affects the hips and knees. The wrist, hand, and elbow joints also may become painful and inflamed.

How offten dose a daycare provider need to do their TB test in CA?

In California, daycare providers are required to undergo tuberculosis (TB) testing every four years. However, if a provider has a known exposure to TB or exhibits symptoms, they may need to get tested sooner. It's important for providers to keep their testing records up to date to comply with state regulations and ensure the health and safety of children in their care.

How long does it take to get tuberculosis sputum culture results?

It can take anywhere from one to eight weeks to get Tuberculosis Sputum culture results. The test will determine if you have Tuberculosis.

How does tuberculosis spread?

Tuberculosis is air born ............................................................. It can spread through the air by people breathing it out.

How effective is chlorine in preventing diseases like cholera?

Chlorine added to drinking water and swimming pools has revolutionised the safety of drinking water throughout the world. The gas dissolves in water and fatallly damages the cell walls of water born bacteria such as eschera coli, (E coli) and cholera. If the water is left to stand the chlorine exits the water and the taste disappears.

A source of safe water is the basis of modern civilization

How are the kidneys affected by TB?

the kidneys are probably the commonest site of extrapulmonary TB. There may, however, be few symptoms even though part of a kidney is destroyed. TB may spread to the bladder. In men, it may spread to the prostate gland and nearby structures.

Is bacteria and bacterium the same?

In the same way that "geese" and "goose" are the same. Bacteria is the plural form of bacterium.

Should employee health conduct a PPD skin test on an immunocompromised healthcare worker?

These are straight from the CDC. Persons receiving prolonged therapy with corticosteroids and other immunosuppressive agents may be at risk for reactivation of TB, but the exact risk is unknown (1). Because prednisone (or its equivalent) given >15 mg/d for 2--4 wk suppresses tuberculin reactivity (55,56), and because lower doses or those given intermittently are not associated with TB, this dose is likely the lower limit that could predispose persons to develop TB (57). Reactivation of TB is more likely to occur in persons receiving higher doses of corticosteroids for prolonged periods of time, especially in populations at high risk for TB, but specific thresholds of dose and duration that could increase the risk for TB are unknown For persons who are at highest risk for developing TB disease if they become infected with M. tuberculosis, a cut-off level of >5 mm is recommended. Persons who are immunosuppressed because of disease (e.g., HIV infection) or drugs (e.g., systemic corticosteroids) have a high likelihood of developing TB disease if they are infected with M. tuberculosis. Previous BCG vaccination. Intracutaneous inoculation with BCG is currently used in many parts of the world as a vaccine against tuberculosis. Tuberculin reactivity caused by BCG vaccination generally wanes with the passage of time but can be boosted by the tuberculin skin test. Periodic skin testing may prolong reactivity to tuberculin in vaccinated persons (74). No reliable method has been developed to distinguish tuberculin reactions caused by vaccination with BCG from those caused by natural mycobacterial infections, although reactions of >20 mm of induration are not likely caused by BCG (75). HIV infection and anergy testing. HIV-infected persons may have a compromised ability to react to tuberculin skin tests because of cutaneous anergy associated with progressive HIV immunosuppression (76). However, the usefulness of anergy testing in selecting tuberculin-negative, HIV-infected persons who might benefit from treatment of LTBI has not been demonstrated (77). Who Can Receive a TST?Most persons can receive a TST. TST is contraindicated only for persons who have had a severe reaction (e.g., necrosis, blistering, anaphylactic shock, or ulcerations) to a previous TST. It is not contraindicated for any other persons, including infants, children, pregnant women, persons who are HIV-infected, or persons who have been vaccinated with BCG

Did Colonel James Bowie have tuberculosis?

No one really knows. He was diagnosed with pneumonia or typhoid pneumonia but many sources say it was probably advanced tuberculosis.

What is the exact meaning of word tuberculosis?

An infectious disease that may affect almost any tissue of the body, especially the lungs, caused by the organism Mycobacterium tuberculosis, and characterized by tubercles.

What was the cure to tuberculosis in Victorian times?

There was no cure back then - you just died. Sometimes they would try to move to a hot, dry climate like the American Southwest, thinking that the hot, dry air would help, but it didn't cure anything.
