  3. 3. Introduction www.freelivedoctor.com
  4. 4. Gynecological, Endocrinological, Cosmetic & Psychogenic: {great anxiety, nature of the disease, social acceptance} www.freelivedoctor.com
  5. 5. Incidence Not known Mediterranean> Asian American females: 10% European: 5% www.freelivedoctor.com
  6. 6. Cycle growth of hair Several months 2 weeks 3 months www.freelivedoctor.com
  7. 7. Types of hair Lanugo Fetal hair Vellus Short, fine, Unpigmented Before puberty Terminal Long, coarse, pigmented arises from vellus hair www.freelivedoctor.com
  8. 8. Non sexual Ambi-sexual Male sexual Sites Lower parts of the scalp, eye brow, lashes, fore-arms, lower legs Temporal & vertical parts of the scalp, axilla, lower pubic hair. Ears, nasal tip, chin, sternum, upper pubic triangle, back. Depend on Growth hormone from pituitary Androgen in low concentration from the adrenals & ovaries in females & adrenals in male Androgen in high concentration Sites of hair www.freelivedoctor.com
  9. 9. Androgen production Androstenedione Testosterone Adrenal DHEA Ovary DHEAS 50% 50% 50% 25% 25% 90% 10% 100% www.freelivedoctor.com
  10. 10. Androgen in the blood Male Normal female Hirsute female Free 3% 1% 2% Albumin 19% 19% 19% SHBG 78% 80% 79% www.freelivedoctor.com
  11. 11. Androgen at target cell (hair follicle) Testosterone (T) 5œ-reductase. Dihydrtestosterone (DHT) Androstanediol Glucuronide 3 alpha androstanediol glucuronide(3 alpha AG) www.freelivedoctor.com
  12. 12. Definitions www.freelivedoctor.com
  13. 13. Virilization: Defiminization: Atrophy of the breast & vagina Musculinization: Hirsutism, deepening of voice, temporal balding. Increase size of the clitoris, muscular mass & libido www.freelivedoctor.com
  14. 14. Hirsutism: Latin hirsutus = shaggy, hairy Excessive growth of terminal hair in male sexual sites. Excessive: Socially unacceptable to the patient F& G score >8 www.freelivedoctor.com
  15. 15. Hypertrichosis Excessive growth of Lanugo, vellus or terminal hair in non-sexual sites (James et al, 2005) •Cong Acquired •Localized Generalized Congenital hypertrichosis lanuginosaDrug-induced hypertrichosis www.freelivedoctor.com
  16. 16. Hirsutism: •Not an increase in the number of hair follicles but an alteration in their character. •An increase in the transformation of the vellus to terminal hair. {Androgens will convert lanugo & vellus hair to terminal hair}. www.freelivedoctor.com
  17. 17. Hirsutism is a consequence of several factors. An increase in: 1. Androgen production 2. The sensitivity of the androgen receptors at the level of the hair follicle. 3. The activity of 5œ-reductase. www.freelivedoctor.com
  18. 18. Causes www.freelivedoctor.com
  19. 19. A. Ovarian: .PCOS: 90% {hyperandrogenism, oligo-ovulation, PCO} .Virilizing ovarian tumors {arrhenoblastoma, hilus cell tumor, lipod cell tumor, granulosa cell tumor} .Luteoma of pregnancy { Not true tumor but an exaggerated reaction of ovarian stroma to chorionic gonadotropins. It is solid, usually unilateral & regress after labour} .Ovarian dysgenesis Turner’s syndromewww.freelivedoctor.com
  20. 20. B. Adrenal: •Cong adrenal hyperplasia •Tumors •Cushing syndrome Congenital adrenal hyperplasia www.freelivedoctor.com
  21. 21. C. PERIPHERAL •Idiopathic: Regular ovulation & normal androgen levels •Insulin resistance – HAIRAN syndrome: HyperAndrogenic Insulin-Resistant Acanthosis Nigricans – 5H syndrome acanthosis nigricans. www.freelivedoctor.com
  22. 22. •Aromatase deficiency •Glucocorticoid resistance •Hyperprolactinema can cause an increase in DHEAS. TT with bromocriptin: dec PRL & DHEAS www.freelivedoctor.com
  23. 23. Hirsutism Anabolic steroids Danazol Metoclopramide Methyldopa Phenothiazines Progestins Reserpine Testosterone Hypertrichosis Cyclosporine Diazoxide Hydrocortisone Minoxidil Penicillamine Phenytoin Psoralens StreptomycinHunter, 2003 D. Drugs www.freelivedoctor.com
  24. 24. Clinical evaluation www.freelivedoctor.com
  25. 25. Primary objective: Confirm diagnosis Determine degree Exclude life threatening diseases www.freelivedoctor.com
  26. 26. History .Virilization, psychological .Onset & duration: Rapidly progressive virilization: androgen secreting tumors .Menstrual history: PCOS, Pregnancy .Family history: Hair patterns are similar in families .Drug intake www.freelivedoctor.com
  27. 27. Examination .General: Thyroid disease, Cushing syndrome, Signs of virilization, Signs of insulin resistance e.g. acanthosis nigricans. www.freelivedoctor.com
  28. 28. .Breast: Galactorrhea {Hyperprolactinaemia can be accompanied by increase in adrenal androgen} .Pelvic: mass www.freelivedoctor.com
  29. 29. Degree of hirsutism Photography or scoring systems a. Ferriman & Gallwey(1961): 9 areas upper lip, chin, chest upper abdomen, lower abdomen, upper arm, thighs, upper back, lower back/buttocks minimal=1, mild=2, moderate=3, severe=4 >8 = hirsutismwww.freelivedoctor.com

  33. 33. Investigations www.freelivedoctor.com
  34. 34. Initial laboratory investigation (Speroph,2005) 1.Total testosterone: measures the ovarian & adrenal activity. 2.17 OHP: an intermediate metabolite in steroidogensis in the adrenals. DHEAS: Good marker of Adrenal A production Not essential www.freelivedoctor.com
  35. 35. •DHES is not essential (Speroff,2005) 1. If 17 OHP is normal: adrenal enzyme defect can be excluded . 2. Moderate elevations of DHES can be suppressed by suppression of ovulation. 3. DHES > 700 ug/dl is rare & is associated with high levels of T 4. Imaging of the adrenals is more cost-effective than measuring DHES. www.freelivedoctor.com
  36. 36. Testosterone (ng/dl) >200 <200 U/S of the ovary Anovulation (PRL, endom biopsy) Adenxal mass Nothing Laparotomy CT of the adrenala & ovaries Laparotomy www.freelivedoctor.com
  37. 37. Free testosterone •Good correlation with total production rate (= secretion rate + peripheral conversion rate) Good correlation with degree of virilization •Free androgen index(FAI)= TX 100 / SHBG if > 4.5: PCOS •Not done routinely in presence of hirsutism www.freelivedoctor.com
  38. 38. 3 alpha androstanediol glucuronide •Metabolite of DHT •Good marker of peripheral androgen action •Inc {increased activity of 5 alpha reductase} {end organ hypersensitivity} •Not done routinely: 1. No change in diagnosis & treatment, 2. Values overlap in 20% www.freelivedoctor.com
  39. 39. Ovarian tumors should be suspected 1. Rapid onset of virilization 2. Unilateral adenxal mass 3. Testosterone >200 ng/dl. •TVS, CT or MRI. www.freelivedoctor.com

  68. 68. III. Local Suppress hair growth: Eflornithine Hydochloride (Vaniqa) Remove hair pigment: Bleaching Temporary depilation: shaving, chemical depilators Temporary epilation: plucking, waxing Permanent removal: Electrolysis, Laser & intense pulsed light www.freelivedoctor.com
  69. 69. 1. Suppress hair growth: Eflornithine 13.9% (Vaniqa) cream •inhibits ornithine decarboxylase (an enzyme in hair dermal papilla that is essential for hair growth). •Face, neck •Minimal s effects, can be used with other tt e.g. lasers, intense pulsed light, regrowth can take 2 ms •Must be continued indefinitely to prevent regrowth S effects: stinging, burning, tingling www.freelivedoctor.com
  70. 70. 2. Bleaching (remove hair pigment) •Hydrogen peroxide, often combined with amonia. •Face, arms •Hair lightens & softens, inexpensive •Hair discoloration, skin irritation, Lack of effectiveness www.freelivedoctor.com
  71. 71. 3. Temporary depilation (remove part of hair) a. Shaving: •All areas •Inexpensive, effective & does not cause change in hair quality, quantity or texture. •Daily need, skin irritation, quick regrowth folliculitis, time consuming, beard stubble www.freelivedoctor.com
  72. 72. b. Chemical depilators: •Break down & dissolve hair by hydrolysing disulhide bonds. •Extremities, groin, face •Quick, inexpensive, effective •Regrowth in days, skin irritation www.freelivedoctor.com
  73. 73. 4. Temporary epilation (remove the entire hair) a. Plucking: •Face, eyebrows, nipples, bikini area •Effective for small amount, inexpensive, regrowth can take weeks • Pain, skin irritation, postinflam pigmentation, folliculitis, slow, ingrown hairs, scarring www.freelivedoctor.com

  75. 75. 5. Permanent removal (destruction of the dermal papilla) a. Electrolysis: •Needle is inserted into the hair follicle & a current is used to destroy the dermal papilla. •All areas, usually the face •May give permanent removal •Pain, scarring, painful, repeat treatments needed, time consuming, expensive, pigmentation www.freelivedoctor.com
  76. 76. b. Laser & intense pulsed light •Selective phototricholysis. A light source sufficient to penetrate to the follicular bulge & the papillae is directed at the hair by probe. •All areas •May give permanent hair reduction, efficient, painless •Dark hair required, expensive, scarring, skin pigmentation, repeated treatments usually necessary www.freelivedoctor.com
  77. 77. IV. Surgery •Tumor •LOD Discrepant & variable response. A modest & sustained improvement in 25% (Amer et al, 2002). www.freelivedoctor.com
  78. 78. Guidelines for management 1. The most desirable & effective tt is combination of OCP & antiandrogen. 2. Response is relatively slow, & at least 6 mo are required to demonstrate an improvement. 3. TT should be continued for at least 1- 2 yr. www.freelivedoctor.com
  79. 79. 4 There is no evidence that one agent is better than another & choices should be governed by cost & side effects. 5. The addition of GnRHa should be reserved for patients resistant to initial therapy. 7. Local methods should be used but reserved until hormonal therapy has reduced the rate of hair growth i.e. after 6 mo. www.freelivedoctor.com
