Abstract:
A patient with a history of Pneumocystis carinii pneumonia (PCP) inhaled aerosolized pentamidine (AP) for secondary prophylaxis of PCP. Nine months after the first PCP episode he presented with pulmonary upper-lobe infiltrations demonstrated by chest x-ray, and bronchoalveolar lavage confirmed the diagnosis of PCP. The clinical course and possible explanations for this unusual form of PCP are presented. The case emphasizes the importance of clinical controls for early diagnosis of relapse of PCP in patients inhaling aerosolized pentamidine. Monitoring of serum lactate dehydrogenase levels appeared to be important in the follow-up of the patient described.

Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
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.
