Is There a Difference in Hirsutism Score in Adolescents with Polycystic Ovary Syndrome on the Basis of Ethnicity and Race?

BACKGROUND: The complex correlation between ethnicity and race, clinical hyperandrogenism as signified by hirsutism, and biochemical androgen concentrations in polycystic ovary syndrome (PCOS) is poorly understood. STUDY OBJECTIVE: The aim of this study was to define the correlation between ethnicity/race and hirsutism score in patients with PCOS. METHODS: We conducted a retrospective chart review of a total of 251 patients with PCOS at the time of diagnosis. Patients were categorized by their ethnicity and race into 5 main groups: Asian (n = 19, 7.6%), Black or African American (n = 11, 4.4%), Hispanic or Latino (n = 26, 10.3%), White (n = 177, 70.5), and others (n = 18, 7.2%). A general linear model was applied using BlueSky software. RESULTS: For the entire study population, the mean age at diagnosis was 15.6 ± 1.7, the mean body mass index (BMI) was 30.6 ± 9.8, the mean hirsutism score using the modified Ferriman-Gallwey score chart was 6.2 ± 3.8, and the mean total testosterone was 40.1 ± 20. The hirsutism score was the highest in the Asian population (mean = 9.1, P = .002) and Hispanic or Latino population (mean = 7.8, P = .02), followed by others (mean = 7.4, P = .04) and the Black or African American population (mean = 7.1, P = .2), compared with the White population (mean = 5.4). This correlation remained significant despite accounting for BMI and androgen levels (P < .001). CONCLUSION: There are factors likely related to hair follicle sensitivity or endogenous response to circulating free androgens that differ between ethnicities and races, such that similar biochemical concentrations lead to differing severity of hirsutism, despite accounting for differences in BMI and androgen levels. More research is needed in this realm to understand the pathophysiologic basis of this interaction.

Defining polycystic ovary syndrome phenotype in Vietnamese women.

AIM: This study aimed to evaluate the unique phenotype of the Vietnamese polycystic ovarian syndrome (PCOS) population. METHODS: In this multicenter cross-sectional descriptive study, a total of 901 reproductive-age women were recruited at three medical centers in Vietnam from June 2016 to May 2018. Group I included 479 patients with PCOS (Rotterdam 2003 consensus) and Group II included 422 non-PCOS women, consisted of women with regular menstrual cycle, collected at the same time of PCOS recruitment, without ovarian disease or ovarian failure. Main outcome measures were anthropomorphic, serum hormone, ultrasound and physical characteristics of PCOS. RESULTS: The Vietnamese PCOS population was lean, but with a higher weight and body mass index compared to controls. About 34.4% of PCOS subjects had hirsutism, primarily confined to the leg, arm and pubis. The PCOS population had higher serum luteinizing hormone (LH), LH : follicle stimulating hormone ratio, anti-Mullerian hormone and testosterone. The PCOS population had double the ovarian volume compared to controls. PCOS subjects had no increase in metabolic disease history and had on average optimal serum markers for low metabolic disease risk. Group D (O + polycystic ovary morphology [PCOM]) was the most prevalent phenotype noted in our Vietnamese PCOS cohort (67.6%). Modified Ferriman-Gallwey, levels of LH, testosterone and anti-Mullerian hormone were highest in Group A (O + H + PCOM) and lowest in Group D (O + PCOM). CONCLUSION: The Vietnamese PCOS population is characterized by a lean body type, nonfacial hirsutism, anovulatory, enlarged ovaries and typical PCOS serum hormone markers, low risk factors for metabolic syndrome. Nonclassical phenotypes for PCOS were more frequent than the classic phenotype.

THE PREVALENCE OF HIRSUTISM AND ETHNICAL PECULIARITIES OF HAIR DISTRIBUTION IN GEORGIAN ADOLESCENT POPULATION IN TBILISI.

Objective - the purpose of the study is evaluation of the Hirsutism prevalence and ethnical peculiarities of the hair distribution in Georgian female adolescents of Tbilisi, Georgia. 2592 randomly selected female adolescents of Tbilisi were included in the study. They completed standard questionnaires consisted of questions about the existence of hirsutism and its locations. For clinical assessment 2 groups were selected from them: group 1 - 117 adolescents with hirsutism and 178 without it. For clinical evaluation of hirsutism modified Ferriman-Gallwey score was used. Based on the self-estimation the hirsutism prevalence was 26.62% (690 out of 2592), while clinically established prevalence of hirsutism was 20.61%. The most prevalent areas of hair distribution by self-estimation were the face and the abdomen. Clinical assessment of patients with hirsutism showed that mean value of Ferriman-Gallwey Score was 12.87±5.94. Hair distribution by clinical assessment was most significantly observed in the lower abdomen (78.33%), upper lip (76.67%) and chest (68.33%). This is the first study of hirsutism prevalence in ethnically Georgian adolescent female population. The study has shown that the value of prevalence by self-estimation exceeds analogous value established clinically, and the sites with hair excess are lower abdomen, upper lip and the chest.

The effect of CAG repeats length on differences in hirsutism among healthy Israeli women of different ethnicities.

PURPOSE: Variations in the degree of hirsutism among women of different ethnic backgrounds may stem from multiple etiologies. Shorter length of the polymorphic CAG repeats of the androgen receptor (AR) gene may be associated with increased activity of the receptor leading to hirsutism. We hypothesized that there are ethnic differences in the degree of hirsutism that is unrelated to androgen levels among Israeli women, and that the CAG repeats length may contribute to these differences. Anti-androgenic therapies, such as spironolactone, could be suggested if a shorter CAG repeats length is found to affect the difference in the degree of hirsutism between the ethnic groups. METHODS: Healthy Israeli Jewish women aged 18-45 years of Ashkenazi and non-Ashkenazi origin were invited to participate. Hirsutism was assessed using the simplified Ferriman-Gallwey (sFG) score, and serum total testosterone levels were measured as well. The CAG repeats length was determined by PCR. Methylation-sensitive methods were used to detect the fractional activity of each allele, and the weighted mean was calculated for the CAG repeats length. RESULTS: One-hundred and eight women were recruited (49 Ashkenazi and 59 non-Ashkenazi). The Ashkenazi women had a significantly lower degree of hirsutism (P<0.01), lower mean BMI (P = 0.003), total testosterone levels (P = 0.017), and longer weighted bi-allelic CAG repeats mean (P = 0.015) compared to non-Ashkenazi women. For the group as a whole, there was a significant negative correlation between the number of CAG repeats in the AR gene and the sFG score, while the number of repeats was not related to testosterone levels. Stepwise logistic regression revealed that ethnic origin and the CAG repeats length were the strongest factors affecting hirsutism (P<0.001, P = 0.03, respectively). CONCLUSIONS: There is a significant difference in the degree of hirsutism between Ashkenazi and non-Ashkenazi women in Israel that is partially explained by CAG repeats length.

Racial and ethnic differences in the polycystic ovary syndrome metabolic phenotype.

BACKGROUND: Women with polycystic ovarian syndrome have a high prevalence of metabolic syndrome and type 2 diabetes mellitus. Blacks and Hispanics have a high morbidity and mortality due to cardiovascular disease and diabetes mellitus in the general population. Since metabolic syndrome is a risk factor for development of type 2 diabetes and cardiovascular disease, understanding any racial and ethnic differences in metabolic syndrome among women with polycystic ovarian syndrome is important for prevention strategies. However, data regarding racial/ethnic differences in metabolic phenotype among women with polycystic ovary syndrome are inconsistent. OBJECTIVE: We sought to determine if there are racial/ethnic differences in insulin resistance, metabolic syndrome, and hyperandrogenemia in women with polycystic ovarian syndrome. STUDY DESIGN: We conducted secondary data analysis of a prospective multicenter, double-blind controlled clinical trial, the Pregnancy in Polycystic Ovary Syndrome II study, conducted in 11 academic health centers. Data on 702 women with polycystic ovarian syndrome aged 18-40 years who met modified Rotterdam criteria for the syndrome and wished to conceive were included in the study. Women were grouped into racial/ethnic categories: non-Hispanic whites, non-Hispanic blacks, and Hispanic. The main outcomes were the prevalence of insulin resistance, metabolic syndrome, and hyperandrogenemia in the different racial/ethnic groups. RESULTS: Body mass index (35.1 ± 9.8 vs 35.7 ± 7.9 vs 36.4 ± 7.9 kg/m2) and waist circumference (106.5 ± 21.6 vs 104.9 ± 16.4 vs 108.7 ± 7.3 cm) did not differ significantly between non-Hispanic white, non-Hispanic black, and Hispanic women. Hispanic women with polycystic ovarian syndrome had a significantly higher prevalence of hirsutism (93.8% vs 86.8%), abnormal free androgen index (75.8% vs 56.5%), abnormal homeostasis model assessment (52.3% vs 38.4%), and hyperglycemia (14.8% vs 6.5%), as well as lower sex hormone binding globulin compared to non-Hispanic whites. Non-Hispanic black women had a significantly lower prevalence of metabolic syndrome (24.5% vs 42.2%) compared with Hispanic women, and lower serum triglyceride levels compared to both Hispanics and non-Hispanic whites (85.7 ± 37.3 vs 130.2 ± 57.0 vs 120.1 ± 60.5 mg/dL, P < .01), with a markedly lower prevalence of hypertriglyceridemia (5.1% vs 28.3% vs 30.5%, P < .01) compared to the other 2 groups. CONCLUSION: Hispanic women with polycystic ovarian syndrome have the most severe phenotype, both in terms of hyperandrogenism and metabolic criteria. Non-Hispanic black women have an overall milder polycystic ovarian syndrome phenotype than Hispanics and in some respects, than non-Hispanic white women.

Ethnic differences: Is there an Asian phenotype for polycystic ovarian syndrome?

Ethnicity has not been accounted for in the diagnostic criteria for polycystic ovarian syndrome (PCOS). It is increasingly recognised that ethnic differences are likely contributors to the differing manifestations of PCOS. Generally, rates of PCOS may be lower in East Asians. It is clear that East Asians are less hirsute than Caucasians. Hirsutism cut-off thresholds need to be lower in East Asian populations than in Caucasian populations. Despite population-adjusted scoring, Caucasians have higher hirsutism rates among patients diagnosed with PCOS. Rates of hyperandrogenaemia do not appear to differ among PCOS subjects, although serum androstenedione appeared to be higher in Caucasians in one study. Interestingly, higher prevalence of the polycystic ovarian morphology has been reported in East Asian PCOS populations than in Caucasian PCOS subjects. Hence, there is a need for comparative studies across different ethnicities to establish whether epidemiological differences observed reflect a true ethnic difference in the phenotype of PCOS and whether there is an Asian phenotype for PCOS.

Women self-perception of excess hair growth, as a predictor of clinical hirsutism: a population-based study.

PURPOSE: Hirsutism is the most common indicator of hyperandrogenism. Both, the sensitivity of the patients to the serum androgen levels and the responsiveness of women to the perceived excess hair growth vary among different populations. This report elaborates the relationship between the woman's discerned abnormal hair growths with the clinical diagnosis of hirsutism. METHODS: The survey was conducted among 1160 women aged 18-45 and randomly selected from Tehran Lipid and Glucose Study for further detailed assessment of Hirsutism; using the m-FG scoring method. Data gathering was performed by interviews and physical examinations. The receiver operating characteristic curve was drawn and the new cutoff value, sensitivity, specificity and concordance percentage were calculated. RESULTS: The results demonstrated that among 12 androgen-dependent body areas, the chin skin had the highest area under curve of 0.81 (CI; 0.78-0.84). According to the patient's evaluation, a threshold point of 4 had the optimum concordance percentage of 0.77 with the modified Ferriman-Gallwey scoring system. CONCLUSIONS: Patient's self-identification of excess terminal hair based on the chin area has great sensitivity and reliability in predicting the clinical hirsutism.

Epidemiologic investigation of polycystic ovarian syndrome (PCOS) in Han ethnic women of reproductive age in Liaoning Province, China.

OBJECTIVE: To determine the incidence of polycystic ovary syndrome (PCOS) among Han women of reproductive age in Liaoning Province in Northeastern China, based on the Revised Rotterdam 2003 criteria. MATERIALS AND METHODS: A retrospective cohort study was carried out on 1,600 women using questionnaires, physical examination, ultrasonography, and biochemical indices (aged = 19 to 45 years; n = 1,600). PCOS patients were identified using the Revised Rotterdam 2003 criteria. RESULTS: A total of 132 Han women of reproductive age were diagnosed with PCOS, with a prevalence of 8.25%. The prevalence of menstrual dysfunction was as follows: 97 patients (73.48%) had abnormal menstruation, three (2.27%) had polymenorrhea, and 94 (71.21%) had oligomenorrhea. Up to 64 patients (48.48%) had androgen excess, 42 (31.82%) had biochemical evidence of androgen excess, and 34 (25.76%) had clinical androgen excess. Up to 34 patients (25.76%) were obese (body mass index [BMI] > or = 25) and 19 (14.39%) had hirsutism (F-G scoring > or = 6). A total of 127 patients (96.22%) were diagnosed with PCOS via ultrasonography, 67 of whom (50.76%) had a unilateral polycystic ovary and 60 (45.46%) had bilateral polycystic ovaries. CONCLUSIONS: The prevalence of PCOS in this study population was 8.25%, with an infertility rate of 27.8%. The classical manifestation of PCOS is PCO, abnormal menstruation, and obesity. The high-risk factors of PCOS include high free testosterone index, homeostasis model assessment-insulin resistance (HOMA-IR), increased serum testosterone and androstenedione, decreased sex hormone-binding globulin, long history of infertility, menarche later than 16 years old, and failure to have regular menstruation within two years.

Phenotypic comparison of Caucasian and Asian women with polycystic ovary syndrome: a cross-sectional study.

OBJECTIVE: To determine whether manifestations of polycystic ovary syndrome (PCOS), particularly androgen excess, differ between Caucasian and Asian women in the San Francisco Bay Area. DESIGN: Cross-sectional study. SETTING: Multidisciplinary PCOS clinic at a tertiary academic center. PATIENT(S): 121 Caucasian and 28 Asian women, aged 18-44, examined between 2006 and 2011 with PCOS verified by a reproductive endocrinologist and dermatologist according to the Rotterdam criteria. INTERVENTION(S): Transvaginal ultrasounds, comprehensive dermatologic exams, and serum testing. MAIN OUTCOME MEASURE(S): Hirsutism defined as a modified Ferriman-Gallwey (mFG) score ≥ 8, acne, androgenic alopecia, and biochemical hyperandrogenism. RESULT(S): Caucasian and Asian women had a similar prevalence of all measures of androgen excess. Both groups had similar total mFG scores and site-specific mFG scores, except Asian women had a lower site-specific mFG score for the chest. Although Asian women were more likely to use laser hair removal, the results were unchanged when the women with a history of laser hair removal were excluded. CONCLUSION(S): Caucasian and Asian women with PCOS living in the same geographic region had a similar prevalence of hirsutism as well as other markers for androgen excess. Further studies are necessary to evaluate the need for ethnic-specific mFG scores in women with PCOS.

Clinical characteristics, metabolic features, and phenotype of Chinese women with polycystic ovary syndrome: a large-scale case-control study.

AIM: The Rotterdam criteria extend the phenotypic spectrum of polycystic ovary syndrome (PCOS). The study was to investigate the clinical and biochemical features of a large-scale clinic based on the samples of Chinese women and to evaluate the value of Rotterdam criteria on Chinese PCOS women. METHODS: One thousand four hundred and four Chinese women were involved in our study, among whom, 719 cases were diagnosed as PCOS based on 2003 Rotterdam criteria, and 685 women without history of hyperandrogenism and with regular menstrual cycles were recruited as control. Clinical features, ultrasonographic (ovarian follicle number and volume), hormonal and metabolic parameters were commenced as outcome measures. RESULTS: Among 719 PCOS women, 6.1 % had hirsutism, 13.3 % had acne, 21.1 % had hyperandrogenism, 94.2 % had polycystic ovaries on ultrasonographic examination, and 88.6 % had menstrual abnormality. About one-third of the total PCOS patients were insulin resistant. The most frequent PCOS phenotype is the non-hyperandrogenic phenotype (O + P). Total testosterone, LH/FSH ratio, body mass index (BMI), and Ferriman and Gallwey scores (F-G) were all significantly higher in PCOS groups compared with non-PCOS group. Women with PCOS and obesity had higher serum testosterone, fasting insulin, longer menstrual cycle and larger ovarian follicle number, and LH/FSH ratio, estradiol or ovarian volume were similar between obese and normal BMI women. The LH level was statistically lower in the obese PCOS group. CONCLUSIONS: Rotterdam criteria are generally applicable to Chinese population. Chinese women with PCOS showed lower rates of hyperandrogenemia, hirsutism, obesity, and insulin resistance. Obesity aggravates menstrual irregularity and increases the follicle number and serum total testosterone level.

Defining hirsutism in Chinese women: a cross-sectional study.

OBJECTIVE: To determine the normative cut-off score that defines hirsutism among Chinese women, and the effect of age, menstrual irregularities, and polycystic ovaries on the same. DESIGN: Cross-sectional, population-based study. SETTING: A multistage systematic cluster random sampling among 16 communities from two rural and two city regions. PATIENT(S): A representative sample of 2,988 women aged 20-45 years from the general population of Southern China. INTERVENTION(S): Subjects underwent physical and ultrasound evaluations. MAIN OUTCOME MEASURE(S): Terminal hair growth was assessed using the modified Ferriman-Gallwey (mFG) scoring system. RESULT(S): An mFG score ≥5 was observed in 10% and a score of ≥2 in 25% of the subjects. Cluster analysis identified an mFG score of 5 as the cut-off value that defines abnormal terminal facial and body hair growth in a male pattern (i.e., hirsutism) in the total population; scores of 6, 5, and 4 for women aged 20-25, 26-30, and >30 years, respectively. Defined by these cut-off values, the prevalence of hirsutism in our total population was 10.5%; and decreased with increasing age: 14.4%, 10.7%, 7.9%, 3.6%, and 1.5%, respectively, in women aged 20-25, 26-30, 31-35, 36-40, and 41-45 years. Furthermore, the incidence of acne, menses irregularities, polycystic ovaries, and acanthosis nigricans were significantly increased among the hirsute women. CONCLUSION(S): An mFG score of 5 or greater indicates hair growth above the norm among women in the general Southern Chinese population, a cut-off value that decreases with increasing age.

Visually scoring hirsutism.

BACKGROUND: Hirsutism is the presence of excess body or facial terminal (coarse) hair growth in females in a male-like pattern, affects 5-15% of women, and is an important sign of underlying androgen excess. Different methods are available for the assessment of hair growth in women. METHODS: We conducted a literature search and analyzed the published studies that reported methods for the assessment of hair growth. We review the basic physiology of hair growth, the development of methods for visually quantifying hair growth, the comparison of these methods with objective measurements of hair growth, how hirsutism may be defined using a visual scoring method, the influence of race and ethnicity on hirsutism, and the impact of hirsutism in diagnosing androgen excess and polycystic ovary syndrome. RESULTS: Objective methods for the assessment of hair growth including photographic evaluations and microscopic measurements are available but these techniques have limitations for clinical use, including a significant degree of complexity and a high cost. Alternatively, methods for visually scoring or quantifying the amount of terminal body and facial hair growth have been in use since the early 1920s; these methods are semi-quantitative at best and subject to significant inter-observer variability. The most common visual method of scoring the extent of body and facial terminal hair growth in use today is based on a modification of the method originally described by Ferriman and Gallwey in 1961 (i.e. the mFG method). CONCLUSION: Overall, the mFG scoring method is a useful visual instrument for assessing excess terminal hair growth, and the presence of hirsutism, in women.

Three-dimensional ultrasound features of the polycystic ovary in Chinese women.

OBJECTIVES: To quantify the three-dimensional (3D) ultrasound characteristics of ovaries in Chinese women with polycystic ovarian syndrome (PCOS) and to compare these with previous data on a Caucasian cohort with PCOS. METHODS: 3D pelvic ultrasound was performed in 40 Chinese women with PCOS and 40 controls. Ovarian volume, stromal volume and echogenicity, and antral follicle count (AFC) were measured and ovarian blood flow was quantified using both 3D power Doppler and two-dimensional (2D) pulsed wave Doppler. These data were compared with previously published data on a Caucasian cohort with PCOS. RESULTS: Compared with controls, women with PCOS had a higher AFC (median (range), 15 (11-30) vs. 5.5 (1-10) per ovary, P < 0.01), ovarian volume (12.32 (8.10-16.16) mL vs. 5.64 (2.62-8.81) mL, P < 0.01) and stromal volume (9.74 (6.44-13.56) mL vs. 4.07 (1.52-6.67) mL, P < 0.01) but were comparable in stromal echogenicity and ovarian blood flow as measured by 3D power Doppler or 2D pulsed wave Doppler indices. However, in comparison with a previously reported Caucasian cohort with PCOS, the ovaries of Chinese women with PCOS had a significantly smaller stromal volume (median (range), 9.74 (6.44-13.56) mL vs. 10.79 (5.65-17.12) mL, P < 0.05), were less echogenic as reflected in a lower mean gray value (22.43 (13.13-35.50) vs. 32.36 (19.35-53.71), P < 0.01), and had reduced ovarian blood flow as reflected in a lower flow index (30.19 (23.32-44.88) vs. 33.54 (21.88-51.65), P < 0.05). CONCLUSION: Based on 3D ultrasound measurements, Chinese women with PCOS have an increased stromal volume compared with controls. However, their stromal volume, echogenicity and vascularity is significantly lower than that in Caucasian women with PCOS. The possible etiology for these differences is discussed.

[Investigation of body hair assessment of Chinese women in Shandong region and its preliminary application in polycystic ovary syndrome patients].

OBJECTIVE: To determine a suitable standard of hirsutism for Chinese polycystic ovary syndrome (PCOS) patients living in Shandong region. METHODS: A total of 623 unbiased women from the general population in Jinan city, 131 PCOS patients and 84 controls from outpatients in Shandong region were studied with questionnaires, physical and pelvic ultrasound examination, body hair on 11 sites were evaluated, and 9 (lip, chin, arm, thigh, chest, upperbelly, lowerbelly, upperback, lowback) of them which were called hormone Ferriman-Gallwey (F-G) score and 2 (forearm, leg) sites of indifferent hormone score were calculated according to the score system described by Ferriman and Gallwey. RESULTS: (1) Both body hair F-G score and indifferent hormone score distribution mode in the or= 2 (chi(2) = 47.68, P < 0.01), but no statistic difference by F-G score >or= 6 criterion (chi(2) = 0.64, P = 0.42). (3) F-G scores were declined with age increase. The hair score on the lip, chest, lowerbelly in general population were positively correlated with F-G score (r = 0.712, 0.594, 0.522; P < 0.01) and in PCOS patients (r = 0.879, 0.682, 0.710; P < 0.01), and on the lip in controls (r = 0.950, P < 0.01). (4) The correlation contingency coefficient between hirsutism (F-G score >or= 2) and lip, chest, lowerbelly site in general population was 0.461, 0.420, 0.489 and was 0.560, 0.532, 0.503 in PCOS group respectively. CONCLUSIONS: (1) Both body hair F-G score and indifferent hormone score distribution mode are significantly different from Ferriman-Gallwey's report; according to our investigation the suitable criterion of hirsutism for Chinese women in Shandong region should be >or= 2 scores. (2) By F-G score >or= 2 standard, hirsutism is more common in PCOS than in control. (3) Lip, chest, and lowerbelly are the main sites to determine the hirsutism status of women, and the later two sites are more specific for PCOS hirsutism. Forearm and leg score can indicate hirsutism status in some degree but are not specific and sensitive for PCOS hirsutism.

The use of a constant spectrum, uniform temporal profile intense pulsed light source for long-term hair removal in Asian skin.

Phototherapy has become a treatment of choice in many areas of medicine. Light can deliver energy to tissue selectively, targeting specific structures in order to induce the desired therapeutic outcome. For the safe and effective removal of unwanted hair, the key optical parameters are wavelength, pulse duration and energy density, and can vary dependent upon skin and hair color. In recent years, the use of broad spectrum white light sources has proved to be safe and efficacious in the removal of hair with minimal short- or long-term side effects. Whilst these highly flexible devices can achieve the desired results, there is scope for improvement. There are two key limitations to these devices: an inability to produce a 'true' long pulse matched to the thermal relaxation time of the hair structure and fluctuations in the output spectrum can lead to ineffective treatment with an increased risk of side effects. This paper describes an alternative approach to producing long pulse, constant spectrum optical pulses and presents clinical data showing improved efficacy in long-term hair removal.

Clinical diagnosis of hirsutism in Thai women.

OBJECTIVE: To determine the cutoff score for identifying hirsute, Thai women, by using modified Ferriman-Gallwey-Lorenzo (mF-G-L) method. MATERIAL AND METHOD: Hirsutism was defined as an amount of terminal hair in the androgen-sensitive skin areas that the women themselves would consider obviously abnormal, and their mF-G-L score was above 97.5 percentile of general population. The subjects were consecutive unselected premenopausal women who came to our hospital for their yearly Papanicolaou smear check up, without any complaint. Acne and oily skin were also assessed. RESULTS: Five hundred and thirty-one women underwent a physical exam. The women who had the total hair-growth score of 0, 1 and 2 by mF-G-L method accounted for 97.8% of all the subjects. All of the 11 subjects with a total score of 3 or more considered themselves to have excessive growth of hair. None of these 11 women had acne. CONCLUSION: The authors purposed that the cutoff score to diagnose Thai hirsutism may be 3 or more by mF-G-L method.

The prevalence and features of the polycystic ovary syndrome in an unselected population.

Notwithstanding the potential public health impact of the polycystic ovary syndrome (PCOS), estimates regarding its prevalence are limited and unclear. Between July 1998 and October 1999, 400 unselected consecutive premenopausal women (18-45 yr of age) seeking a preemployment physical at the University of Alabama at Birmingham were studied (223 Black, 166 White, and 11 of other races). Evaluation included a history and physical examination, a modified Ferriman-Gallwey hirsutism score, and serum screening for hyperandrogenemia, hyperprolactinemia, and 21-hydroxylase-deficient nonclassical adrenal hyperplasia. PCOS was diagnosed by the presence of the following: 1) oligoovulation, 2) hyperandrogenemia and/or hirsutism (modified Ferriman-Gallwey score > or = 6), and 3) the exclusion of related disorders. Confirmed PCOS was established in those individuals whose evaluation was complete and indicative of PCOS, and possible PCOS was established when the hormonal evaluation was not complete or was unavailable, but the clinical phenotype was otherwise suggestive of the disorder. The individual probability of PCOS in women with possible PCOS was assigned a weight based on the findings in similar subjects whose evaluation was complete, and the total number of PCOS cases arising from these individuals was calculated (i.e. individual probability of PCOS x total number of subjects in the group). The cumulative prevalence of PCOS in our population was 6.6% (26.5 of 400), including 15 subjects among the 347 women completing their evaluation and a calculated prevalence of 11.5 subjects among the remainder. The prevalence rates of PCOS for Black and White women were 8.0 and 4.8%, respectively, not significantly different. These data from a large representative unselected population support the concept that PCOS is the most common endocrine abnormality of reproductive-aged women in the United States.

Ethnic hair update: past and present.

Hair and scalp disorders in African American patients are challenging because of the lack of pathophysiologic explanations for many of the disorders that occur in this population. To understand the clinical appearance of these disorders and to design an effective treatment plan, the dermatologist must have a clear knowledge of the basic hair-care practices and concerns of this group of patients. Given that patients of African American heritage are not a homogeneous group, this overview describes many of the common hair-care practices of African Americans and how they affect patients' health. The common hair and scalp disorders are discussed, with a specific focus on inflammatory disorders that result in significant pigmentation alteration or scarring.

Hirsutism in the United Arab Emirates: a hospital study.

In a study of 102 women (Arabs and Asians) with hirsutism, polycystic ovary syndrome was diagnosed in 93 patients (91%) including 26 cases with hirsutism and regular menstrual periods. In more than half of the cases the diagnosis was made on the basis of transabdominal ultrasonography, which was the single test with the highest yield. Luteinising hormone hyperresponsiveness to gonadotropin-releasing hormone was positive in only seven of 50 patients tested. Late onset congenital adrenal hyperplasia due to 21-hydroxylase deficiency was identified in two cases, thus forming a prevalence of 8% in those who underwent adrenocorticotropin stimulation. In one case, polycystic ovary syndrome was an associated condition. In this study of a population of women with hirsutism and regular menses, the majority had polycystic ovaries. It is suggested that the term 'idiopathic or racial' hirsutism should not be applied unless a thorough evaluation has failed to reveal a diagnosable underlying disorder.
