Case:
We present the case of an otherwise healthy 77-year-old male retired firefighter and recreational pheasant hunter who presented with recurrent symptoms of carpal tunnel syndrome and tenosynovitis because of Mycobacterium szulgai. He was initially treated unsuccessfully for a presumed seronegative rheumatologic flare, followed by surgical diagnosis and treatment including revision carpal tunnel release with tenosynovectomy, and a secondary debridement and wound closure. His symptoms resolved after several months of multidrug antibiotic therapy with only mild residual median nerve deficit.
Conclusion:
Nontuberculous Mycobacterium infections of the upper extremity are extremely rare and challenging to diagnose/treat. This report highlights diagnostic and surgical challenges in this rarely reported infection.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
