miliary tuberculosis (redirected from Tuberculosis, miliary)

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.

miliary tuberculosis,

extensive dissemination by the bloodstream of tubercle bacilli. In children it is associated with high fever, night sweats, and often meningitis, pleural effusions, or peritonitis. A similar illness may occur in adults but with a less abrupt onset and occasionally with weeks or months of nonspecific symptoms, such as weight loss, weakness, and low-grade fever. Multiple small opacities resembling millet seeds may be evident on chest x-ray films. The liver, spleen, bone marrow, and meninges are often affected. The tuberculin test result may be negative, and diagnosis is made by biopsy of the infected tissue or organ. Combined drug therapy with isoniazid, rifampin, and pyrazinamide is usually successful if the diagnosis is not delayed. Concurrent tuberculous meningitis makes the prognosis less favorable. See also Mycobacterium, tuberculosis.
