Hirsutism: a brief review

Guidance for the management of hirsutism

Approximately 80% of women are affected by the presence of excessive hair growth in a 'male-like' pattern. Excessive facial hair in particular can be a source of distress to such women and can lead to psychological problems such as anxiety, depression and a reduced quality of life.Current cosmetic methods of hair removal include shaving, depilatories, waxing, plucking, laser, intense pulsed light (IPL) and electrolysis.A topical treatment cream such as eflornithine 11.5% can slow hair growth and thus reduce the frequency of the need for hair removal. This treatment can be used effectively in conjunction with hair removal methods.

Sexual desire in women presenting for antiandrogen therapy

Women presenting with hirsuties/polycystic ovary syndrome have increased production of androgens. Clinical lore suggests that these women may have increased sexual desire. Treatment of hirsuties commonly involves antiandrogen therapy, a form of therapy with a potential for reducing sexual desire. The present study investigated sexual desire in 29 hirsute women aged 19 to 43 years presenting for therapy. We conducted a questionnaire appraisal of the women's sexual desire, body and self-esteem, and affect at baseline, 3 months, and 12 months and compared the data with a control group of 30 nonhirsute women of similar mean age. Those in the treatment group also had their Ferriman and Gallwey scores and body mass indices calculated at baseline and end of study for those in the treatment group. We determined hormone levels for those in the treatment group with baseline blood tests. Our hypotheses were that the hirsute women would experience different levels of sexual desire than the control group prior to therapy and that therapy would have a demonstrable effect on the self-reported sexual desire of these women. The study demonstrated that women with hirsuties had mean levels of sexual desire and body esteem that were significantly lower than the control group women. During the year-long course of therapy, the sexual desire levels of the hirsute women decreased progressively, while their self-esteem increased. The women's Ferriman and Gallwey scores fell, indicating diminishing hirsutism. These findings provide empirical data upon which clinicians can base advice to patients seeking therapy.

Successful reduction in skin damage resulting from exposure to the normal-mode ruby laser in an animal model

Normal-mode ruby laser (NMRL) irradiation of skin has now become an acceptable method of producing depilation. However, side effects, which include superficial burning and changes in skin pigmentation, still occur and, although temporary, can be distressing to the patient. This paper reports a method by which the skin can be protected (or preconditioned) from damage during NMRL treatment by pre-heating to a lower, non-damaging level prior to irradiation. Using the black-haired mouse (C57B1/10) as an animal model, an appropriate 'preconditioning' temperature was established by exposing the mouse skin to a range of temperatures, taking biopsies and staining the skin immunohistochemically for heat shock protein 70 (HSP 70) expression within the keratinocyte cells. Increased HSP 70 expression is stimulated by exposure to environmental stressors such as heat, so it was hypothesised that its increased expression conveyed increased cellular protection. The appropriate temperature (45 degrees C for 15 min) allowed for the superficial skin cells to be protected (as assessed by maximal HSP 70 staining) but undamaged (as assessed by haematoxylin and eosin staining), leaving the target hair-producing cells unprotected. Eight mice (16 flanks) were then exposed to this preconditioning temperature (eight of the flanks being growing-hair sites and eight resting-hair sites) and 5 h later exposed to a laser fluence known to cause mild skin damage and depilation (6J/cm2). This exposure was to both the preconditioned and the adjacent non-preconditioned sites. A statistically significant reduction in skin damage (P <0.001), as measured by the time taken to heal and noted both clinically and histologically, was seen in the preconditioned sites in resting-hair regions but not in growing-hair regions. Depilation, established over an 8 week period, was successful in growing-hair regions within both preconditioned and non-preconditioned sites, but complete hair regrowth had occurred in preconditioned and non-preconditioned sites within resting-hair regions by 5 weeks. The latter finding was consistent with work already reported suggesting that NMRL-assisted depilation in this animal model is not successful for hairs in the telogen phase. Successful preconditioning of mouse skin prior to laser exposure appears to reduce NMRL-induced skin side effects. In addition, the technique does not appear to adversely affect successful depilation.
