Summary
Optic nerve damage from isoniazid is rare in children but occurred in a 10-year-old treated for tuberculous meningitis. Symptoms improved after stopping isoniazid and using pyridoxine and steroids.
Area of Science:
- Pediatric Neurology
- Ophthalmology
- Infectious Diseases
Background:
- Isoniazid (INH) is a primary treatment for tuberculosis.
- Optic neuropathy is a known but rare side effect of INH therapy.
- Pediatric cases of INH-induced optic neuropathy are not well-documented.
Observation:
- A 10-year-old boy with tuberculous meningitis developed optic nerve involvement.
- The patient was undergoing treatment with isoniazid.
- Clinical presentation included visual disturbances indicative of optic neuropathy.
Findings:
- This case represents a rare instance of isoniazid-induced optic neuropathy in a pediatric patient.
- The adverse reaction was observed during treatment for tuberculous meningitis.
- Complete resolution of symptoms was achieved.
Implications:
- Highlights the potential for isoniazid to cause optic nerve damage in children.
- Emphasizes the importance of monitoring for visual disturbances during INH therapy in pediatric populations.
- Suggests pyridoxine and corticosteroid administration as effective management strategies for INH-induced optic neuropathy.

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...

Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
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.

Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
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 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:
