Insights

A 7-month-old infant initially diagnosed with pneumonia developed severe acute respiratory distress syndrome (ARDS). Autopsy revealed miliary tuberculosis, highlighting diagnostic challenges in infants with negative tuberculin skin tests.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Pulmonology

Background:

  • Infants presenting with respiratory symptoms require careful differential diagnosis.
  • Mycoplasma infections can mimic other respiratory illnesses in infants.
  • Tuberculosis (TB) in infants can present atypically and pose diagnostic challenges.

Observation:

  • A 7-month-old infant with suspected interstitial pneumonia and positive Mycoplasma antigen test was treated with erythromycin.
  • The infant experienced rapid respiratory deterioration, developing tension pneumothorax and severe acute respiratory distress syndrome (ARDS).
  • Despite intensive care, sustained respiratory stabilization was not achieved.

Findings:

  • Autopsy confirmed miliary tuberculosis, with a subpleural parenchymal focus in the left lung and hematogenous spread.
  • Tuberculous meningitis was also diagnosed.
  • The source of infection remained unidentified, and the infant's tuberculin skin test (TST) was negative.

Implications:

  • This case underscores the importance of considering miliary tuberculosis in infants with severe respiratory failure, even with negative TST.
  • Diagnostic delays can occur when atypical presentations of childhood TB are not recognized.
  • Improved diagnostic strategies for infant TB are crucial for timely and effective treatment.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Tuberculosis01:23

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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 Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
