Pili annulati
Pili annulati (pronunciation: /ˈpiːliː ˌænjuːˈlɑːtiː/) is a rare genetic disorder that affects the hair. The term is derived from the Latin words 'pili' meaning 'hair' and 'annulati' meaning 'ringed'. This condition is characterized by the appearance of alternating light and dark bands on the hair shaft, giving it a ringed or beaded appearance.
Symptoms
The primary symptom of pili annulati is the distinctive appearance of the hair. The hair shafts exhibit a pattern of light and dark bands, which are visible under light. This is due to the irregular arrangement of keratin, the protein that makes up hair, in the hair shaft.
Causes
Pili annulati is a genetic disorder, which means it is caused by abnormalities in the genes. It is inherited in an autosomal dominant manner, which means that an affected person has a 50% chance of passing the disorder to each of their children. The specific genes involved in pili annulati are not yet fully understood.
Diagnosis
Diagnosis of pili annulati is typically based on the characteristic appearance of the hair. A microscopic examination of the hair may be performed to confirm the diagnosis. Genetic testing may also be used to identify the presence of the disorder in the genes.
Treatment
There is currently no cure for pili annulati. Treatment is typically focused on managing the symptoms and improving the appearance of the hair. This may include the use of special hair care products or techniques to minimize the visibility of the bands.
