Insights

Treatment for central nervous system tuberculosis tuberculomas may require longer than the standard 1 year. Extended anti-tuberculous therapy duration, based on imaging, can lead to lesion resolution in pediatric cases.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pediatrics

Background:

  • Central nervous system tuberculosis (CNS TB) requires anti-tuberculous therapy (ATT).
  • Standard treatment duration for tuberculomas is typically 1 year.
  • Guidelines for extended ATT in persistent CNS TB tuberculomas are lacking.

Observation:

  • A series of six pediatric CNS TB cases with persistent tuberculomas were analyzed.
  • Patients received ATT for 23–32 months, guided by neuroradiological scan resolution.
  • Treatment response was monitored via changes in granuloma size and number.

Findings:

  • All patients showed a decrease in tuberculoma size and number.
  • One patient achieved complete resolution of lesions.
  • After ATT cessation, granuloma size stabilized in most cases, with one showing an increase.

Implications:

  • Extended ATT duration may be necessary for complete resolution of CNS TB tuberculomas.
  • Treatment duration should be individualized based on patient response and imaging.
  • Further research is needed to establish definitive guidelines for prolonged ATT in CNS TB.

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group Therapy

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Behavior Therapy

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...
