A Prospective Study Examining Trigger Factors and Hormonal Abnormalities in Adult Female Acne.

Background: Numerous triggers have been implicated in adult female acne including endogenous (hormonal dysfunction and genetic predisposition) and exogenous causes (drugs, cosmetics, sunscreens, stress, and smoking).

Aims: To evaluate the role of various trigger factors in adult female acne and to analyze the androgenic hormone pattern including anti-Mullerian hormone (AMH) in these patients.

Materials And Methods: Patients having acne of age ≥25 years were analyzed using a pre devised proforma to elicit trigger factors while the severity was graded using the Global Acne Grading System (GAGS).

A study comparing the clinical and hormonal profile of late onset and persistent acne in adult females.

Background: Adult acne has been classified into two major subtypes: "persistent acne" and "late onset acne". A surrogate marker of hyperandrogenism (HA) in adult female acne is the presence of clinical signs of HA and biochemical hyperandrogenemia. We compared the clinical and hormonal profiles of the two acne subtypes and evaluated the likely source of androgen excess - ovarian or adrenal.

A prospective study examining isolated acne and acne with hyperandrogenic signs in adult females.

Background: Adult female acne (AFA) occurs beyond 25 years of age and can present either as isolated acne or with hyperandrogenic signs.

Methods: 120 females aged ≥ 25 years were evaluated for acne, hirsutism and androgenetic alopecia. Hormonal assessment included total testosterone (TT), sex hormone binding globulin (SHBG), free androgen index (FAI), Anti Mullerian Hormone (AMH), 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), follicle stimulating hormone (FSH), luteinizing hormone (LH), thyroid stimulating hormone (TSH) and prolactin.

A Spilt Head Study of Efficacy of Placebo versus Platelet-rich Plasma Injections in the Treatment of Androgenic Alopecia.

Background: Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma with haemostatic and tissue repairing effects. Being enriched by various growth factors, PRP has become the focus of attention in numerous fields of medicine. Androgenic alopecia (AGA) is a common chronic hair loss disorder, characterised by progressive hair loss.
