Insights

Cat-scratch disease, caused by Bartonella henselae, can lead to severe neurological issues like encephalopathy. Early diagnosis and azithromycin treatment led to a full recovery in a pediatric case.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Ophthalmology

Background:

  • Cat-scratch disease is caused by Bartonella henselae, a bacterium.
  • While some Bartonella infections resolve spontaneously, others can be fatal without antibiotic treatment.

Observation:

  • A 7-year-old male presented with a 2-week history of malaise and cervical lymphadenopathy.
  • Symptoms progressed to fever, headache, vomiting, confusion, and meningism.
  • Unusual retinal findings and evidence of Bartonella henselae infection were noted.

Findings:

  • Lumbar puncture showed elevated cerebrospinal fluid protein, low glucose, and increased white blood cells.
  • Antibody titers to Bartonella quintana supported the diagnosis of cat-scratch disease.
  • The patient exhibited unexplained encephalopathy and atypical retinal findings.

Implications:

  • This case highlights the potential for Bartonella henselae to cause severe neurological complications in children.
  • Prompt diagnosis and treatment with azithromycin are crucial for favorable outcomes.
  • Ophthalmological examination is important in diagnosing atypical presentations of cat-scratch disease.

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...

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

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...

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Rabies01:28

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...
