    1. ACNEDisorders of sebaceous gland

    3. Incidence: Acne affect all skin types, the male and female ratio is virtually the same but tend to be more severe in males. 85% affect the age group 12 24 years 8% affect the age group 25 34 years 3% affect the age group 35 44 years

    4. Etiology: Genetic Aspect, (Acne runs in family) other example the case of severe acne that is associated with XXY syndrome. Occupation (Environmental, Mechanical) e.g. exposure acnegenic mineral oil (Pomade acne) dioxin Drugs Oral and topical Hydrocortison (Steroid acne) Lithium, Hydantoin, contraceptives Endocrine Factors (Recalcitrant Acne, POD/s, MARSH Syndrome) .

    5. Pathogenesis: ( three main steps recognized and hypothesized) 1. Follicular Hyperkeratosis (the cause not fully understood) theory suggest: deficiency in Linoleic acid, the effect off 5-a reductase enzyme on converting Androgen (Testosterone) hormone to the active acnegenic and potent (Dihydrotestosterone) DHT, the direct effect of Interleukin-1 on follicular hyperkeratosis

    7. 2. Abnormal production of abnormal sebum increasing the ratio of wax easter to cholesterol and cholesterol easter and is believed to be the response of sebaceous glands to DHEA

    8. 3. Colonization of the affected unit with bacteria Propionibacterium acne and yeast named Malassezia furfur

    10. Propionobacterium acne lipases act on sebaceous fatty acid (Triglycrides) to release irritant free fatty acid and low-molecular- weight peptide an extra cellular factor that penetrate the follicular wall and stimulate Polymorphs and Lymphocytes initiating inflammation

    11. Hydrolytic enzymes released from the activated complement antibodies complex together with exoenzymes produced from P acne cause rupture of follicular wall

    12. Once the wall is damaged Various agents (prostaglandin-like substance, amino acid, short chain fatty acid are) that are produced by the inflammatory cells and P acne extrude to the dermis causing more inflammation

    13. Clinical features: (Acne and acne related Disorders) Acne Vulgaris: Papules: (Less than 0.5 cm) Comedones (Open Blackheads or closed Whitheads)

    14. Open Comedones (Blackheads)

    15. Closed Comedones (Whitehead)

    16. Inflammatory papules

    17. Pustules :

    18. Nodule (more than 0.5 cm)

    19. Cystic acne: the cysts are usually large 1-4cm

    20. 2. The nodules and cysts could be associated with sinuses as in Acne inversea Acne inversea (Hidradinitis supprativa a misleading name) because it is considered by some to be disorder of apocrine gland (Sweat gland) but In my opinion Acne inversea affect primarily pilo Seb. Unit and affect secondarily the sweat gland, hence the correct name Acne inversea rather than Hidradinitis supprativa is preferred.

    22. Neonatal acne: cause unknown but some believed is due to passing of Transplacental androgen other suggest the role of Mlalassezia furfur and sympodalis . affect 1 in 5 mainly inflammatory comedones on nose and cheeks affect new born between the 1st and 6th week of age

    24. Infantile Acne: affect males more than females, usually between 3 and 6 months of age, and tend to be severer than the neonatal one and believed to be due to Endogenic androgen from the infants gonads.

    26. 4. Recalcitrant Acne Affect Women and associated with (Adrenal hyperplasia "11-B- or 21-B hydroxlase deficiencies) acne is usually nodulocystic

    27. 5. Acne Fulminans Affect youngsters 13 17 years of age, very severe with ulceration and puss discharge, associated symptoms include (fever malase myalgia arthritis and bone pain) laboratory investigation shows ESR Can be induced by starting the patient on high dose of isotretinion (Roaccutane).

    29. 6. Acne Conglobata Very severe Acne, Nodulocystic form with abscess formation, affect Torso more than the face, usually associated with XYY Syndrome.

    31. 7. Acne Agminata (Lupus Milliaris Disseminatus Faciei) Some believe it is form of Rosacea (Granulomatous type), diagnosis is made at Histological base, Caseating Granulomata at the dermal level.

    33. 8. Acne as part of other syndromes MARSH Syndrome (Melsma, Acne, Rosacea, ,Seborrhoeic eczema, and Hirsutism) Acne Conglobata Favre Racouchot syndrome elderly with elastosis as part of Helioderma, sun exposure is a predisposing factor. Polycystic ovarian syndrome Atrophoderma vermiculatum as part of so called Ulerythema ophryogenes triat in Noonan Syndrome, de Lange Syndrome, and Rubinstein-Taybi Syndrome Not considered acne

    34. 9. Occupational I Environmental Chloracne rare forms of acne affect patients exposed to Halogenated Hydrocarbons or who ingested Chlorinated Phenols (Dioxin) Pomade acne or known as Oil Folliculitis Acne Aestivalis or so called Mallorca Acne

    35. Occupational II mechanical acne Folicullitis Nuchae or so called Acne Keloidalis Pseudofollicultis barbae Acne excoriee as part of Psychodermatosis

    36. TRAETMENT

    37. Topical Keratolytic Retinoid ( Retinoic acid 0.025, 0.05, 0.1%) Adapelene (Diffrine 0.1%) Salicylic acid Benzoic acid Azelaic Acid (10, 15, 20 %)

    38. Topical Antibiotic Topical clindamycin (Dalacin T) Erythromycin Mupirocin (Bactroban) Sodium Fusidic acid (less significant in the treatment)

    39. Systemic therapy Antibiotic (Macrolides and Tetracyline) Tetracycline Doxycycline Minocycline (Photo sensitivity and LE) Erythromycines Clarythromycines Azithromycine

    40. Systemic Retinoid Isotretinoine caps (Roaccutane) New promising and potentially safe medication SMT D002 Phase I clinical trial Is believed to treat seborrhoea a symptom of Parkinson's disease and the primary cause of acne

    41. Other form of therapy Systemic steroid (Prednisolone) acne fulminans and intralesional steriods for forms of cystic acne. Photodynamic therapy i.e. Laser therapy and phototherapy (Less significant) Hormonal therapy (Antiandrogen) Spironlacton (Potassium sparing agent) and Metformin as (Hypogylcemic agent) in treatment of POS have good results on acne
