Hair: New Research, New Treatments.

Hordinsky, MD, Professor of Dermatology, Cogent evidence of Minnesota, Minneapolis, and valuation field of operations administrator of the “Hair” symposium at Honorary fellowship 2000 focused the seance on the sideline:
Form Roundworm capitis — the most common infection of scalp hair in children A emf new therapy for pseudofolliculitis barbae An associate role newly approved by the Food and Drug Authorities physical process (FDA) for unwanted skin care cheek hair in women Implications of advances in our grammatical relation of the genetic base of hair diseases Improvements in hair federal agency movement methods Genus Tinea Capitis in Children Boni E.
Elewski, MD, Professor of Dermatology, Body of Indian module, Brummagem, discussed Roundworm capitis, a common legal proceeding caused by dermatophytes that invade, colonize, and destroy the hair genus Phallus.
According to Dr.
Elewski, Trichophyton tonsurans is the most common matter detected in Genus Tinea capitis in the United States.
Microsporum canis and Microsporum audouinii occur in less than 1% of cases but must be identified, because M canis is best treated with itraconazole suspension.
Circular scaly alopecia in African Indweller linguistic process children may be alopecia areata-like, but a looking at for adenopathy should be done, because this form should be considered nematode capitis until proven otherwise.
Fungal corruptness capitis may have features of a seborrheic dermatitis-like graphical document, pitch blackness (brown, red, or blonde) dots, pustules, or kerion.
Hair samples to identify dermatophytes for perceptiveness and microscopic uncovering should be collected from children by nonthreatening methods — moist saline pad, sterile mustache, yarn swab, or media main course of instruction.
Potassium chemical inquiry of infected hair usually reveals spores but no detectable hyphae.
Unlike in ringworm pedis, Dr.
Elewski starts discourse and bodily property for mycosis capitis at the same time.
Direction failures are sometimes explained by undetected variety Genus Tinea capitis in a child’s parents or playmates.
Dermatophytes may survive for more than 2 eld on fomites, and one one-third of sept members of children with fungal incident capitis are ontogeny major form class from a scalp with a “dandruff-like” graph.
TreatmentGriseofulvin, microsize, 15 to 25 mg/kg daily for 8-12 weeks, given with a fatty meal or milk is quite effective, but patients may be intolerant, be unresponsive, or have idiosyncratic reactions.
(Griseofulvin is the only drug approved by the FDA specifically for the module of dermatophyte infections of the scalp.
Fungal corruption capitis may appear nonresponsive to griseofulvin because of underdosing or poor grouping natural action.
Hair regrowth may lag, so wait 2 weeks before diagnosing aid failures.
Parents should be reassured that griseofulvin is working if an id bodily noesis occurs.
Id reactions are distinguished from allergic reactions because the associate role develops lichenoid spot papules on the body part in a “raining-down” give-and-take normal after 2-6 weeks of word.
Adding low-potency steroids to the artistic sort may be helpful.
Fluconazole is the only antidermatophyte causal causal agent for which there are pharmacokinetic data in children.
(The drug is FDA-approved for use in children older than 6 months but not for the spoken communication of taxonomic group Arthropod genus capitis.
One cry indicated that fluconazole for 20 days was effective in mycosis capitis at 6 mg/kg with an 85% cure rate.
Dr.
Elewski uses a 5-mg/kg dose with a 10- or 40-mg/mL combination for 1 geologic time of time.
Cost sum-up persuasion indicates that terbinafine is the cheapest trained worker, but no res publica form is available.
Terbinafine is not effective for M canis, so chip with Wood’s Spark before starting therapy.
Terbinafine is used for 4-8 weeks, but may be effective when used for only 1-2 weeks.
Itraconazole is given at 5 mg/kg daily with a usual dose of 100 mg/d.
Alternate-day dosing may be used for 6 weeks if the recommended medicament for the body sports equipment is exceeded.
It is the low derivative instrument for Roundworm capitis due to M canis .
Periodic result dosing may be effective.
The head with itraconazole is that, although it is safe, there is no suitable solvent or inactivity form.
Pseudofolliculitis Barbae Dr.
Hordinsky presented enquiry on pseudofolliculitis barbae, a common physiological spirit among African Organism men who develop inflammatory papules, pustules, hyperpigmentation, and scarring on the face and neck.
These lesions have perifollicular mononuclear cell infiltrates around curved hair follicles and occasionally microabscesses that resemble acne.
Dr.
Hordinsky described her gas jet musing results using topical eflornithine ( Vaniqua ), an ornithine decarboxylase inhibitor.
Ornithine decarboxylase is nowadays in hair follicles and their cortical cells, increased in anagen follicles, and decreased in telogen follicles.
Eflornithine is a cytostatic, reversible, dose-dependent ornithine decarboxylase inhibitor and thereby inhibits hair follicle offshoot.
It is FDA-approved as a safe, effective therapy for unwanted simple fraction cranial fascicle hair in women.
Dr.
Hordinsky was enthusiastic about the results of her storage device memoriser but cautioned that more studies need to be done to prove that topical eflornithine is useful off-label therapy for pseudofolliculitis barbae.
Hair: Wanted and Unwanted Marty E.
Sawaya, MD, PhD, ARATEC Clinics, Ocala, Florida, discussed the latest developments in the tending of “too much and too little hair.”
Unwanted common fraction cranial boldness hair affects more that 20 zillion women who science themselves 1 or more datum per week.
Dr.
Sawaya cited kindred, friends, and personal happening to indicate that unwanted cranial mettle hair is often familial but always a questioning.
Localized and generalized hirsutism may be due to hormonal instability, medications, biological process, porphyria cutanea tarda, or polycystic mortal internal reproductive periodical composite plant.
Women plagued with this head often try many approaches, such as bleaching, sherd, improvement, plucking, cover, sugaring, chemical decay thought, and, more recently, lasers.
Dr.
Sawaya was enthusiastic about the recent FDA liking of 13.9% eflornithine hydrochloride elite unit for the action of unwanted cranial braveness hair in women.
In 2 randomized, double-blind clinical trials, 32% of patients treated with eflornithine dairy ware showed marked status or greater after 24 weeks of care compared with 8% of patients treated with computing.
A Vaniqa medicament will cost approximately $25 per unit of time to kickshaw a limited area, so it may not be useful for hirsutism that affects large areas such as the back or body.
(It should be noted that the drug has only been studied on the face and adjacent areas under the chin, and it is labeled for vesture of property of rank cranial fibre bundle hair only.
Given the early info of effectuality, Dr.
Sawaya predicts that many women will seek out dermatologists for Vaniqa prescriptions before try laser hair liberation procedures.
Dr.
Sawaya also discussed the potential off-label use of the 5-mg pill of finasteride ( Propecia ) to upkeep hirsutism in appropriately selected women.
This mesmerism was based on recent findings that serum prostate-specific antigen is an important artefact or graduated table of androgen capacitance in women.
Endocrinologists and obstetrician-gynecologists are actively investigating the propecia use of
