Sub-Category:

Neurocysticercosis

Symptoms:
seizures; headache; nausea; vomiting; vision problems; hydrocephalus; altered mental status

Root Cause:
Infection of the central nervous system by Taenia solium larvae (pork tapeworm), leading to cyst formation in the brain.

How it's Diagnosed: videos
Neuroimaging (MRI or CT) revealing cysts or calcifications, serologic tests for T. solium antibodies, and CSF analysis.

Treatment:
Antiparasitic therapy with albendazole or praziquantel, corticosteroids to reduce inflammation, anticonvulsants for seizure management, and surgical intervention in severe cases.

Medications:
Albendazole (antiparasitic), praziquantel (antiparasitic), dexamethasone (corticosteroid), and levetiracetam or phenytoin (anticonvulsants).

Prevalence: How common the health condition is within a specific population.
Leading cause of acquired epilepsy in developing countries; affects millions globally, particularly in regions with poor sanitation.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Consumption of undercooked pork, poor sanitation, close contact with infected individuals, and living in endemic areas.

Prognosis: The expected outcome or course of the condition over time.
Favorable with treatment in uncomplicated cases; long-term anticonvulsant therapy may be required for seizure control.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic epilepsy, hydrocephalus, intracranial hypertension, and neurological deficits.

Strongyloidiasis

Specialty: Infectious Diseases

Category: Gastrointestinal Tract and Intra-abdominal Infections

Sub-category: Parasitic Infections

Symptoms:
abdominal pain; diarrhea; weight loss; itchy skin rash; cough or wheezing in disseminated cases

Root Cause:
Chronic intestinal infection caused by the parasitic nematode Strongyloides stercoralis, with potential for autoinfection and systemic dissemination.

How it's Diagnosed: videos
Stool examination, serological tests (antibody detection), or PCR. Larvae may also be identified in duodenal aspirates or sputum in disseminated cases.

Treatment:
Anti-parasitic therapy with ivermectin or albendazole.

Medications:
Ivermectin (first-line) or albendazole (alternative). Both are anti-helminthic drugs.

Prevalence: How common the health condition is within a specific population.
Common in tropical and subtropical regions; less frequent in temperate areas.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Poor sanitation, immunosuppression, corticosteroid use, and travel to endemic regions.

Prognosis: The expected outcome or course of the condition over time.
Excellent with timely treatment; life-threatening in disseminated strongyloidiasis.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Hyperinfection syndrome, sepsis, and respiratory distress in severe cases.
