A tuberculoma is a clinical manifestation of tuberculosis which conglomerates tubercles into a firm lump, and so can mimic cancer tumors of many types in medical imaging studies. [1] [2] They often arise within individuals in whom a primary tuberculosis infection is not well controlled. [3]
Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. [1] [9] People with latent TB do not spread the disease. [1] Active infection occurs more often in people with HIV/AIDS and in those who smoke. [1]
Tuberculous meningitis, also known as TB meningitis or tubercular meningitis, is a specific type of bacterial meningitis caused by the Mycobacterium tuberculosis infection of the meninges—the system of membranes which envelop the central nervous system.
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Treatment of active TB disease is typically a combination of antibiotics, which results in patients being non-infectious to others usually within a few weeks. Until that point, though, patients can spread TB to others and it’s typically adults with reactivated TB that are the most infectious.
The tine test is a multiple-puncture tuberculin skin test used to aid in the medical diagnosis of tuberculosis (TB). The tine test is similar to the Heaf test, although the Mantoux test is usually used instead. There are various forms of the tine tests which usually fall into two categories: the old tine test (OT) and the purified protein ...
A tuberculosis outbreak in Long Beach, California, led the city to declare a public health emergency. It comes amid a national rise in tuberculosis cases.
The needle points were dipped in tuberculin purified protein derivative (PPD) and pricked into the skin. [5] A Heaf gun with disposable single-use heads was recommended. The gun injected PPD equivalent to 100,000 units per ml to the skin over the flexor surface of the left forearm in a circular pattern of six.
