Insights
Congenital tuberculosis is challenging to diagnose in infants, often requiring consideration of maternal history. Early suspicion and treatment are crucial for favorable outcomes in neonates with suspected tuberculosis.
Area of Science:
- Pediatrics
- Infectious Diseases
- Neonatology
Background:
- Congenital tuberculosis presents diagnostic challenges in infants due to non-specific symptoms and often negative standard test results.
- Identifying the source of transmission in infant tuberculosis cases can be difficult.
Observation:
- A one-month-old infant presented with irritability, tachypnea, fever, poor weight gain, and hepatomegaly.
- The infant's mother had a history of pre-extensively drug-resistant tuberculosis and placental findings indicative of Mycobacterium tuberculosis.
Findings:
- The infant was diagnosed with suspected congenital tuberculosis based on clinical signs and maternal history.
- Treatment resulted in a favorable clinical evolution and no adverse reactions.
Implications:
- Congenital tuberculosis diagnosis should be considered in infants presenting with suggestive clinical signs.
- A maternal history of Mycobacterium tuberculosis infection warrants maintaining a high index of suspicion for congenital tuberculosis.
Abstract:
Tuberculosis in infants is a clinical case difficult to diagnose by regular testing which often yield negative results; additionally, the source of transmission is difficult to identify. This work presents the case of a one-month old nursing boy presenting irritability, tachypnea, fever, poor gain weight from birth, and hepatomegaly. Additionally, he had the maternal history of pre-extensively drug- resistant tuberculosis and tuberculoid granulomatosis reaction with positive auramine tincture for acid-alcohol resistant bacilli at histopathology of the placenta. With a suspected congenital tuberculosis, he was referred to the National Children's Health Institute for diagnosis and treatment. The patient showed a favorable clinical evolution and no adverse reactions to treatment. The diagnosis of congenital tuberculosis must be considered in infants with suggestive clinical signs of the disease and such suspicion must be maintained with the presence of a maternal history of Mycobacterium tuberculosis infection.

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
Pre-mRNA Processing: Modification of pre-mRNA Ends
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps...
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...

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...
