THE WOMEN WITH THE WORM IN
HER HEAD
Chapter 8
The women with the worm in her head
Juan Barrera, Oscar Enriquez
PATIENT’S SYMPTOMS
 Speech Problems
 Losing syllables.
 Losing words.
 Apraxia of speech.
 Abnormal finger temperature
 Right hand fingers colder than left hand fingers.
 Asymmetry of face
 Muscles on right side of face not as strong as left.
 Twitching on right side.
CAUSATIVE AGENT
 Taeniasis: Adult tapeworm in intestine. (Taenia solium).
 Attach to wall of small bowel by hooks.
 Tapeworm can grow to be over 3 yards long.
 No symptoms because it is very thin and flat.
 It can live in host for up to 10 years.
 Reproduces by fertilizing its own eggs.
 Cysticercosis: Infection of tissue after exposure to tapeworm
eggs.
 Cysticerci: Encysted larvae of pork tapeworm
 Found in pig muscles.
 Neurocysticercosis
 Oncosphere released.
 Carried by bloodstream all over body.
 Found in brain.
 Develop into mature larval worms.
 Eating undercooked pork
 Cysticerci in pig tissue.
 Ingested by humans, releasing larvae.
 Thousands of eggs released into stool everyday.
 Person to Person transmission
 Carrier of adult tapeworm.
 Tapeworm egg.
 Egg digested releasing living embryo called oncosphere.
 Raw food
 Salads or fruits in contact with contaminated sewage.
HOW IS CYSTICERCOSIS
ACQUIRED/TRANSMITTED?
AVAILABLE TREATMENTS
 Cysticercosis is treated with a combination of anti-
inflammatory and anti-parasitic drugs.
 Decadron is used as an anti-inflammatory, to prevent
swelling and seizures from happening.
 Praziquantel and Albendazole are used to kill the
parasite.
 When the patient is not responsive to the treatment,
surgery may be required to remove the encysted larvae.
PREVENTATIVE MEASURES
 Neurocysticercosis is endemic in Latin America, Africa,
and in some regions of the Far East.
 When traveling to a developing country.
 Wash and peel raw vegetables and fruits before eating.
 Drink only bottled or boiled water. Avoid water from
drinking fountains and ice cubes.
 Wash your hand frequently.
 Prepare your own food.
SIGNIFICANCE TO THE PUBLIC HEALTH
 Neurocysticercocis is the most common parasitic
infection of the brain.
 It is the most frequent cause of seizures throughout
world.
 Identification of tapeworm carriers is important for the
public health to prevent further cases of cysticercosis.
SIGNIFICANCE TO THE PUBLIC HEALTH CONT..
 1,800-2,000 persons are diagnosed with neurocysticercosis
each year in the United States. Cases are most frequently
reported in New York, California, Texas, Oregon, and Illinois.
 Approximately 50 million people are believe to have
cysticercosis worldwide.
