REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Epilepsy ll: Types

Epilepsy ll: Types

Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.

Inborn Errors of Metabolism

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Rabies

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...

Encephalitis ll: Pathophysiology

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...

Summary

Reye syndrome, a rare metabolic encephalopathy in children, may mimic inborn errors of metabolism. Investigations for fatty-acid oxidation defects are crucial in suspected Reye-like illness.

Area of Science:

Biochemistry
Pediatrics
Neurology

Background:

Reye syndrome is an acute metabolic encephalopathy primarily affecting children and adolescents.
Reye-like syndrome can manifest due to inborn errors of metabolism, presenting with hypoglycemia, hypoketonemia, elevated ammonia, and organic aciduria.
Fatty-acid oxidation defects are known to present as Reye-like syndrome, with medium-chain acyl coenzyme A dehydrogenase deficiency being the most commonly diagnosed.

Observation:

Reye syndrome is considered rare, prompting investigations for inborn errors of metabolism in suspected cases.
A case of Reye-like illness possibly linked to long-chain acyl dehydrogenase deficiency and aspirin ingestion was recently treated.
The study discusses the potential pathogenesis of this specific case.

Findings:

Mitochondrial dysfunction is implicated in the pathogenesis of both Reye syndrome and Reye-like illness.
Long-chain acyl dehydrogenase deficiency is presented as a possible cause of Reye-like illness.
The findings highlight the overlap in clinical presentation and underlying pathophysiology.

Implications:

This case underscores the importance of investigating metabolic disorders, particularly fatty-acid oxidation defects, in children presenting with Reye-like symptoms.
Early diagnosis and management of these underlying metabolic conditions are critical.
Understanding the role of mitochondrial dysfunction can lead to improved diagnostic and therapeutic strategies for Reye-like illnesses.
