Epidermal

Epidermal

Description: upper layer of the skin, primary and secondary morbidity occurs, six major EPSD are scabies, pediculosis (capitis, corporis and pubis), tungiasis and hookworm-related cutaneous larva migrans

Symptoms: itching

Method of diagnosis: usually determined by the infected/affected individual

Causes: stigma, lack of access to health care and deficient behaviour in seeking health care

Prevention: have safe sex for scabies, keep up good hygiene (for scabies)

Treatments/Cures: treat promptly, get diagnosed promptly

Epidemiology: scabies, pediculosis capitis and pediculosis pubis occur worldwide but pediculosis corporis is restricted to cold-climate countries, tungiasis only in the Caribbean, sub-Saharan Africa and South America

Symptoms: soft, small (but can grow big), sometimes painful

Method of diagnosis: physical exam, biopsy

Causes: likely genetic

Prevention: can’t

Treatments/Cures: can be removed surgically and with liposuction

Epidemiology: being 40-60 years old increases your chance of getting one

Keloid

Description: a raised area caused by an overgrowth of scar tissue, flesh-colored, red, or pink, nodular or ridged, at the site of an injury or wound

Symptoms: itchy

Method of diagnosis: made by looking at the skin, sometimes a biopsy is needed

Causes: can occur after an injury to the skin has healed (such as a burn), at the site of intentional alterations of the skin (such as an ear piercing), or as the result from medical procedures or illnesses (such as a vaccination or the chickenpox), it is thought that they are due to the body’s failure to turn off the healing process needed to repair skin

Prevention: avoid trauma to the skin, compression pressure dressing for high-risk patients who have suffered burns to their skin, prompt and proper treatment of skin abrasions and cuts, for physicians: close incisions with as little tension on the sutures as possible, and to use buried sutures whenever possible

Treatments/Cures: injection of corticosteroid drugs (thinner), laser treatment, radiation therapy, topical treatments are undergoing study, cryosurgery (freeze the keloid with liquid nitrogen), silastic gel sheeting (flattens),

Epidemiology: commonly found in women and young people under the age of 30, families, people with darker skin, and infrequently among the elderly.
