Insights
Routine tuberculosis screening for hospitalized children in high-risk Houston, Texas, identified few new infections. This study suggests hospital-based screening may not be an effective strategy for detecting childhood tuberculosis.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Harris County, Texas, including Houston, exhibits high childhood tuberculosis (TB) case rates.
- Tuberculosis remains a significant public health concern, particularly in pediatric populations.
Purpose of the Study:
- To evaluate the effectiveness of routine tuberculin skin testing during hospitalization for acute medical care in children.
- To determine if hospital admission is a suitable setting for identifying asymptomatic tuberculous infections in children.
Main Methods:
- A 11-week screening program was conducted in spring 1988 at Ben Taub General Hospital, Houston, TX.
- All children admitted to the medical service received a Mantoux tuberculin purified protein derivative skin test.
- Data collection focused on evaluable skin test results at 48 hours.
Main Results:
- A total of 432 children were skin tested; 50% were under one year of age.
- Only 304 patients had evaluable results at the 48-hour mark.
- Two new positive tuberculin skin tests were identified, yielding a positive rate of 0.66%.
Conclusions:
- Routine tuberculin screening of all hospitalized children in a high-risk region yielded a low positive rate.
- The study suggests that inpatient pediatric medical services may not be an effective or efficient setting for routine tuberculosis screening.
- Alternative or targeted screening strategies may be more appropriate for identifying pediatric tuberculosis infections.
Abstract:
Harris County, TX, which includes Houston, has one of the highest childhood tuberculosis case rates in the United States. For an 11-week period in the spring of 1988 all children admitted to the medical service of the Ben Taub General Hospital in Houston, TX, received a Mantoux skin test consisting of tuberculin purified protein derivative. The purpose was to assess the impact of routine tuberculin screening during hospitalization for acute medical care and to determine whether tuberculin screening in this setting is an effective means of identifying children with asymptomatic tuberculous infection. Of the 432 patients skin tested, 50% were younger than 1 year of age and only 304 were evaluable at 48 hours. Two new positive skin tests were discovered for a positive tuberculin rate of 0.66%. We conclude that even in a high risk region, routine tuberculin screening of all children admitted to the hospital may not be effective.

Pneumonia III: Complications and Assessment
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.

Pulmonary Tuberculosis II
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...

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...
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...
