The effects of conformation and intermolecular hydrogen bonding on the structure and IR spectra of flutamide; a study based on the matrix isolation technique, ab initio and DFT calculations. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 292:122417.

Abstract
In this study, stable conformers of flutamide referred to as an anticancer drug were searched through a relaxed potential energy surface scan carried out at the B3LYP/6-31G(d) level of theory. This was followed by geometry optimization and thermochemistry calculations performed with the HF-SCF, MP2, B3LYP methods and the 6-31G(d), 6-311++G(d,p), aug-cc-pvTZ basis sets for each of the determined minimum energy conformers. The results revealed that flutamide has at least five stable conformers and two of them provide the major contribution to the observed matrix isolation infrared (IR) spectra of the molecule. The effects of conformational variety and intermolecular hydrogen bonding interactions on the observed IR spectra of flutamide were interpreted in the light of the vibrational spectral data obtained for the most stable monomer and dimer forms of the molecule at the same levels of theory. Pulay's "Scaled Quantum Mechanical-Force Field (SQM-FF)" method was used in the refinement of the calculated harmonic wavenumbers, IR intensities and potential energy distributions. This scaling method which proved its superiority to both anharmonic frequency calculations and other scaling methods helped us to correctly interpret the remarkable differences between the matrix IR spectra of flutamide in argon and the condensed phase IR spectra of the molecule in solvents such as KBr, H2O, D2O, ethanol and methanol.

Abstract
BACKGROUND After dermatitis, acne is the next skin disease to contribute most to the burden of skin diseases worldwide. Recently, seven core outcome domains have been identified, which together form an Acne Core Outcome Set (ACORN). One of these was satisfaction with acne treatment. OBJECTIVES To identify studies that described the development of patient-reported outcome measures (PROMS), evaluated one or more measurement properties of a PROM, or evaluated the interpretability of a PROM in patients with acne regarding treatment satisfaction. METHODS The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) search strategy for identifying PROMS on acne treatment satisfaction was used. We searched PubMed, MEDLINE, Embase, LILACS, Web of Science, Cochrane Library, Emcare, PsycINFO and Academic Search premier (June 2020). Study selection, data extraction and assessment of methodological quality according to COSMIN guidance were carried out independently by two authors. RESULTS Only one study could be included, describing the development of a treatment satisfaction measure in patients with acne. The development was assessed as inadequate and data on measurement properties were lacking. Additionally, we found 188 studies reporting treatment satisfaction solely as an outcome, using a wide variety of methods, none of them standardized or validated. CONCLUSIONS We could not find a PROM on treatment satisfaction to recommend for a core outcome set in acne. There is an unmet need for a PROM on treatment satisfaction in acne that is robustly developed, designed and validated.

Abstract
Hyperandrogenism is a condition affecting 5-10% of adolescents. The aim of this study was to evaluate the efficacy of very low dose of flutamide in the treatment of hyperandrogenism in adolescence. One hundred and fifty-eight patients, presenting severe acne and/or hirsutism, received 62.5 mg/day of flutamide + ethinylestradiol + gestodene for 18 months. The patients were subjected to assessments of hepatic enzymes levels. Thirty subjects treated with drospirenone + ethinylestradiol represented the control group. After 18 months of treatment, it was obtained a decrease of hirsutism (-39.9%), an almost recovery of acne (98% of patients) with better results of those obtained in control group. Only one case of light hypertransaminasemia was recorded, regressed spontaneously. Very low dose of flutamide was successful and safe and in the treatment of hyperandrogenism in adolescence.

Abstract
PURPOSE OF REVIEW Acne vulgaris is a global disease with increasing prevalence in adolescents. It has a profound impact on their quality of life, especially when endocrine disorders are also involved. Recent concerns regarding antibiotic stewardship, failures with antibiotic usage, and the development of antibiotic-resistant Propionibacterium acnes have led clinicians to consider other therapeutic options for acne treatment. The present review explores hormonal therapies for the treatment of acne vulgaris. RECENT FINDINGS There are now four different combined oral contraceptive pills that are FDA approved for the treatment of acne since its first introduction in 1960. Recent literature has provided more information on the efficacy of different generations of combined oral contraceptive pills, their side-effects, and cancer risks. Furthermore, spironolactone has been gaining wider use among dermatologists in adolescents with endocrine dysfunction. New diagnostic guidelines and treatment recommendations have also been suggested. SUMMARY Hormonal therapies are effective and well tolerated options for the treatment of acne vulgaris in adolescents with and without endocrine disorders. They can be used as monotherapy or in conjunction with benzoyl peroxide, topical retinoic acid, or antibiotics.

Abstract
Hormone-based therapies including combined oral contraceptive medications and spironolactone are considered effective therapies to treat adult acne in women. Our objective is to provide a concise and comprehensive overview of the types of hormonal therapy that are available to treat acne and comment on their efficacy and safety profiles for clinical practice. A systematic search using the PubMed Database was conducted to yield 36 relevant studies for inclusion in the review and several conclusions were drawn from the literature. Treatment with oral contraceptive pills leads to significant reductions in lesion counts across all lesion types compared with placebo. There were no consistent differences in efficacy between the different combined oral contraceptive formulations. In terms of risk, oral contraceptive pill users had three-times increased odds of venous thromboembolism versus non-users according to a recent meta-analysis (95% confidence interval 2.46-2.59). Data on oral contraceptive pill use and breast cancer risk are conflicting but individual patient risk factors and histories should be discussed and considered when prescribing these medications. However, use of these medications does confer measurable protection from endometrial and ovarian cancer. Spironolactone was also shown to be an effective alternative treatment with good tolerability. Combined oral contraceptive medications and spironolactone as adjuvant and monotherapies are safe and effective to treat women with adult acne. However, appropriate clinical examinations, screening, and individual risk assessments particularly for venous thromboembolism risk must be conducted prior to initiating therapy.

Abstract
OBJECTIVE To evaluate the long-term safety, satisfaction and tolerability of flutamide therapy for female hyperandrogenism. DESIGN A 20-year surveillance study. METHODS Setting: Gynecology Department in a teaching hospital. PATIENTS Hyperandrogenic women complaining for hirsutism treatment were followed between February 1995 and April 2015. INTERVENTIONS Women received flutamide 125 or 250 mg/day alone (n = 55) or combined with oral contraceptives (n = 65). MAIN OUTCOME MEASURES Adverse events, safety, tolerability satisfaction and efficacy were assessed every 6 months during all the follow-up. Lab tests including liver and lipid profiles were also recorded in each control. RESULTS Patients under flutamide therapy showed significant improvements in hirsutism scores after 6 months of treatment with a maximum effect at 12 months that was maintained during all the therapy time. Satisfaction reported by patients with the efficacy of the drug in a visual scale was also high. A total of 54.2 % women presented one or more adverse effects during the follow-up; 33.3% showed at least one adverse effect possibly related with the study drug; and 24.1% withdrew from the study because of adverse effects. During the follow-up, as many as 89.9 % of patients abandoned flutamide. Reasons include: questions linked to medical problems (50%), attempt pregnancy (4%) and significant improvement in the symptomatology (35.8%). CONCLUSIONS Flutamide is very effective for hirsutism treatment; however, adverse effects are very frequent and affect compliance.

Abstract
The long-term effects and tolerability of flutamide (Flu) on the menstrual cycle and the ovulatory function of hyperandrogenic women with or without polycystic ovary syndrome (PCOS) were investigated. The study included 118 white women with the diagnosis of various forms of hyperandrogenism (80 PCOS and 38 non-PCOS patients). Patients received Flu for three years at dosages that declined each of the three years (250, 125 and 62.5 mg/day). Sex steroid, ovulatory function and menstrual profile at baseline and during each year of Flu treatment were evaluated. Flu therapy showed a significant increase in the percentage of cycles that were ovulatory (with progesterone concentrations greater than 4 ng/ml in mid-luteal phase) and concomitant regularization of the menstrual profile in PCOS patients. A luteinizing hormone decrease and an estrone, estradiol and 17-hydroxyprogesterone increase are also observed during treatment. Regular cycles persisted in non-PCOS patients. The results were maintained during the three years of treatment. The study suggests that Flu is a satisfactory therapeutic regimen of the chronic anovulation and the irregularities of the menstrual cycle in hyperandrogenic PCOS patients in the long run.
