Insights

Acute necrotizing encephalopathy, a rare childhood brain disorder, is linked to influenza. Early diagnosis and treatment, including hypothermia, significantly improve outcomes for affected children.

Area of Science:

  • Pediatric Neurology
  • Infectious Diseases

Background:

  • Acute necrotizing encephalopathy (ANE) is a rare, severe neurological disorder predominantly affecting young children in East Asia.
  • It typically follows an upper respiratory infection and is associated with influenza viruses.

Observation:

  • The case describes a 4-year-old Caucasian girl presenting with fever, altered consciousness, and seizures.
  • Influenza A was confirmed via nasal swab, and magnetic resonance imaging revealed characteristic brain lesions.

Findings:

  • The hallmark of ANE includes multifocal, symmetric brain lesions in the thalami, brainstem, white matter, cerebellum, and medulla.
  • Historically, ANE had a dismal prognosis with high mortality and severe neurological sequelae.

Implications:

  • Prompt recognition and management of ANE are crucial for improving patient outcomes.
  • Treatment with hypothermia and anti-inflammatory agents may lead to favorable recovery, even in non-Asian populations.

Decreased Body Temperature01:29

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
Methods of reducing fever01:22

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.

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...
