Insights

Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus (PANDAS) involves neuropsychiatric issues in children. This study found only 5.2% of analyzed cases were linked to a prior streptococcus infection.

Area of Science:

  • Pediatric Neurology
  • Infectious Diseases
  • Psychiatry

Context:

  • PANDAS (Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus) describes neuropsychiatric disorders in children following streptococcal infections.
  • This study investigated the clinical presentation and potential association with Group A beta-hemolytic streptococcus (GABHS) in pediatric patients.

Purpose:

  • To clinically analyze 38 patients under 16 with tics, Tourette Syndrome (TS), or Obsessive Compulsive Disorder (OCD).
  • To explore the association between these conditions and GABHS infections.

Summary:

  • The study reviewed 38 patients (86.8% male) diagnosed with tics, TS, or OCD, with symptom onset most common in schoolchildren.
  • Comorbidities included learning difficulties (78.9%), ADHD (71.1%), and OCD (36.8%). Abnormal EEG patterns were observed in 72.4% of patients.
  • A link to streptococcus infection was identified in only 5.2% of the cases, aligning with existing literature.

Impact:

  • Provides clinical insights into PANDAS spectrum disorders in a pediatric cohort.
  • Highlights the prevalence of comorbidities like learning difficulties and ADHD in affected children.
  • Suggests a low direct association with streptococcal infection in this specific patient group, warranting further research into underlying mechanisms.

Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Streptococcal Pharyngitis01:27

Streptococcal Pharyngitis

Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
