pulmonary tuberculosis

tuberculosis /tu·ber·cu·lo·sis/ (-sis) any of the infectious diseases of humans and other animals due to species of Mycobacterium and marked by formation of tubercles and caseous necrosis in tissues of any organ; in humans the lung is the major seat of infection and the usual portal through which infection reaches other organs.

avian tuberculosis  a form affecting various birds, due to Mycobacterium avium, which may be communicated to humans and other animals.

bovine tuberculosis  an infection of cattle due to Mycobacterium bovis, transmissible to humans and other animals.

disseminated tuberculosis  an acute form of miliary t.

genital tuberculosis  tuberculosis of the genital tract, e.g., tuberculous endometritis.

tuberculosis of lungs  pulmonary t.

miliary tuberculosis  a form varying in severity, in which minute tubercles form in different organs due to dissemination of bacilli through the body by the blood stream.

open tuberculosis 

1. that in which there are lesions from which tubercle bacilli are discharged out of the body.

2. pulmonary tuberculosis with cavitation.

pulmonary tuberculosis  tuberculosis of lungs; infection of the lungs by Mycobacterium tuberculosis, with tuberculous pneumonia, formation of tuberculous granulation tissue, caseous necrosis, calcification, and cavity formation. Symptoms include weight loss, fatigue, night sweats, purulent sputum, hemoptysis, and chest pain.

renal tuberculosis  renal disease due to Mycobacterium tuberculosis.

spinal tuberculosis  osteitis or caries of vertebrae, usually as a complication of pulmonary tuberculosis.

Infectious disease Infection by Mycobacterium tuberculosis, which occurs primarily–85% of cases, US–in the lungs Epidemiology TB is spread by aerosol from coughing or sneezing by infected Pt Clinical 1º infection is usually asymptomatic, 95% of Pts–US recuperate without further evidence of disease; PT develops in immunocompromised Pts, generally within wks after the primary infection or may lie dormant for yrs before causing disease At risk population Infants, elderly, and immunosuppressed–eg, chemotherapy, posttransplant Pts receiving immunosuppressants, or those with immunodeficiency–eg, AIDS; PT ranges from minimal to massive involvement, but progresses in all without therapy Risk factors Frequent contact with Pts with TB, crowding, unsanitary living conditions, poor nutrition; TB is rising in the US, due to AIDS, homelessness, drug-resistant strains of TB, incomplete treatment of TB–eg, poor compliance.
