Objective:
To make a descriptive analysis of the clinical characteristics of patients with pulmonary tuberculosis and find the time of diagnostic delay.
Design:
Retrospective study.
Setting:
Autonomous Community of Navarre.
Patients:
317 cases of pulmonary tuberculosis diagnosed between January 1 1993 and June 30 1996.
Results:
The most commonly observed symptom was coughing (76.8%), followed by expectoration (63.8%) and high temperature (60.3%). The high percentages of high temperature, asthenia, anorexia and weight loss in HIV-infected patients stood out. The mean period of diagnostic delay was 36.9 to 58.5 days, with a median of 15 days. For 76.8% of patients the delay in diagnosis was under a month.
Conclusions:
Early diagnosis is essential in tuberculosis control, especially in cases transmitted by bacilli, since these are highly contagious for months.

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...

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
