The medical history includes obtaining the symptoms of pulmonary TB: productive, prolonged cough of three or more weeks, chest pain, and hemoptysis.Systemic symptoms include low grade remittent fever, chills, night sweats, appetite loss, weight loss, easy fatiguability, and production of sputum that starts out mucoid but changes to purulent.

Although Richard Morton established the pulmonary form associated with tubercles as a pathology in 1689, [21] [22] due to the variety of its symptoms, TB was not identified as a single disease until the 1820s. Benjamin Marten conjectured in 1720 that consumptions were caused by microbes which were spread by people living close to each other. [23]
If there is any question of active TB, sputum smears must be obtained. Therefore, any applicant might have findings grouped in this category, but still have active TB as suggested by the presence of signs or symptoms of TB, or sputum smears positive for AFB. [2] The main chest X-ray findings that can suggest inactive TB are: [2] 1.
It is clear that the spread of this strain of TB is closely associated with a high prevalence of HIV and poor infection control; in other countries where XDR-TB strains have arisen, drug resistance has arisen from mismanagement of cases or poor patient compliance with drug treatment instead of being transmitted from person to person.

[2] [3] Cigarette smokers are 25% more likely to have lung damage, and more severe damage, after cure of a TB infection. [5] People who cook with 3-4 stoves instead of 1-2 stoves are more likely to have lung damage. A lack of heating also increased how often symptoms occurred. Alcoholism also increased the risk of PTLD. Ambient air pollution ...
This area is known as a “Ghon focus”. TB also gets to nearby hilar lymph nodes, either carried over by immune cells through the lymph or by direct extension of the Ghon focus infection and causes caseation there as well, and together, this caseating tissue and associated lymph node make up the characteristic “Ghon complex”.
TB Bacteria Are Spread Only from a Person with Active TB Disease ... In people who develop active TB of the lungs, also called pulmonary TB, the TB skin test will often be positive. In addition, they will show all the signs and symptoms of TB disease, and can pass the bacteria to others.
Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampicin. Some forms of TB are also resistant to second-line medications, and are called extensively drug-resistant TB .
