The p190 RhoGAPs, ARHGAP35, and ARHGAP5 are implicated in GnRH neuronal development: Evidence from patients with idiopathic hypogonadotropic hypogonadism, zebrafish, and in vitro GAP activity assay.

PURPOSE: The study aimed to identify novel genes for idiopathic hypogonadotropic hypogonadism (IHH). METHODS: A cohort of 1387 probands with IHH underwent exome sequencing and de novo, familial, and cohort-wide investigations. Functional studies were performed on 2 p190 Rho GTPase-activating proteins (p190 RhoGAP), ARHGAP35 and ARHGAP5, which involved in vivo modeling in larval zebrafish and an in vitro p190A-GAP activity assay. RESULTS: Rare protein-truncating variants (PTVs; n = 5) and missense variants in the RhoGAP domain (n = 7) in ARHGAP35 were identified in IHH cases (rare variant enrichment: PTV [unadjusted P = 3.1E-06] and missense [adjusted P = 4.9E-03] vs controls). Zebrafish modeling using gnrh3:egfp phenotype assessment showed that mutant larvae with deficient arhgap35a, the predominant ARHGAP35 paralog in the zebrafish brain, display decreased GnRH3-GFP+ neuronal area, a readout for IHH. In vitro GAP activity studies showed that 1 rare missense variant [ARHGAP35 p.(Arg1284Trp)] had decreased GAP activity. Rare PTVs (n = 2) also were discovered in ARHGAP5, a paralog of ARHGAP35; however, arhgap5 zebrafish mutants did not display significant GnRH3-GFP+ abnormalities. CONCLUSION: This study identified ARHGAP35 as a new autosomal dominant genetic driver for IHH and ARHGAP5 as a candidate gene for IHH. These observations suggest a novel role for the p190 RhoGAP proteins in GnRH neuronal development and integrity.

Impaired Sexual Function in Young Women With PCOS: The Detrimental Effect of Anovulation.

BACKGROUND: Even though polycystic ovary syndrome (PCOS) is a common reproductive disorder affecting young women, its impact on their sexual health is not well known. AIM: To examine the different aspects of female sexuality in young women with PCOS and attempt to associate hormonal changes and ovulatory status with their sexual function. METHODS: Anthropometric characteristics, hormonal levels and sexual function based on the Female Sexual Function Index (FSFI) questionnaire were assessed in 76 young women with PCOS and 133 matched controls. OUTCOMES: Sexual function is significantly impaired in young women with PCOS. RESULTS: Women with PCOS demonstrated lower scores than controls in arousal (5.04 ± 1.19 vs 4.48 ± 1.44, P < .001), lubrication (5.29 ± 1.17 vs 4.69 ± 1.54, P < .001), orgasm (4.78 ± 1.40 vs 4.11 ± 1.61, P = .001), satisfaction (5.22 ± 1.10 vs 4.78 ± 1.31, P = .016), and total score of the FSFI (29.51 ± 5.83 vs 26.76 ± 6.81, P < .001), even after correction for BMI. When corrected for total testosterone, the domains of lubrication, satisfaction, and total score of FSFI remained significantly impaired in women with PCOS (P values .037, .024, & .044 respectively). In multivariate logistic regression analysis, after adjusting for the effect of BMI and hormone levels, dysfunction in orgasm, satisfaction and the total FSFI score were still 3-4 times more common in PCOS (adjusted OR [95% CI]: 3.54, P = .020; 2.96, P = .050; 3.87, P = .027). Even though no statistically significant differences were observed between women with ovulatory PCOS and controls, we detected statistically significant differences in all domains of sexual function apart from pain between controls and PCOS women with anovulation (desire P value .04, arousal P value <.001, lubrication P value <.001, orgasm P value .001, satisfaction P value .001 and FSFI total score P value <.001). CLINICAL IMPLICATIONS: Women with PCOS have compromised sexual function, which is independent of their BMI and highly dependent on their ovulatory status. STRENGTHS AND LIMITATIONS: This is the first study in women with PCOS that implicates anovulation as a risk factor for sexual impairment in PCOS. Further studies are needed to elucidate the mechanisms implicated and to examine the effect of PCOS therapy on the patients' sexual function. CONCLUSION: The adverse effect of PCOS status on the female sexual function is independent of BMI and only partially dependent on hormonal changes characterizing the syndrome. Anovulation appears to be the major determinant of sexual impairment among women with PCOS. Mantzou D, Stamou MI, Armeni AK, et al.

Association of Calpain (CAPN) 10 (UCSNP-43, rs3792267) gene polymorphism with elevated serum androgens in young women with the most severe phenotype of polycystic ovary syndrome (PCOS).

OBJECTIVES: To highlight a possible association of Calpain (CAPN 10) gene UCSNP-43 polymorphism with hormonal and metabolic traits of young women with different phenotypes of polycystic ovary syndrome (PCOS). DESIGN: PCOS women were genotyped for the CAPN 10 gene UCSNP-43 polymorphism. A comparison of clinical and biochemical features of women with PCOS stratified on the basis of the CAPN 10 gene UCSNP-43 variants was assessed. METHODS: Anthropometric, hormonal and biochemical measurements were carried out in 668 PCOS women and 200 healthy controls. Subjects were also genotyped for the CAPN 10 gene UCSNP-43 polymorphism. The genotype frequency distributions between groups and controls were compared using the chi-square test. The association of the polymorphism with the clinical and biochemical features of the study cohort was estimated as well. RESULTS: No association of the frequency of CAPN 10 gene UCSNP-43 polymorphism with PCOS was detected. No association of the polymorphism with the anthropometric, biochemical and hormonal features was detected both in PCOS and control women. The polymorphism was associated with serum Δ4 androstenedione (p = 0.018), as well as with 17-OH progesterone (17-hydroxyprogesterone) among women with PCOS phenotype A (p = 0.012). CONCLUSIONS: CAPN 10 gene polymorphism UCSNP-43 is deprived of a metabolic contribution to cardiovascular disease (CVD). However, due to its association with androgen excess in phenotype A, CAPN 10 gene polymorphism UCSNP-43 could be used as a genetic marker for CVD in young PCOS women.

Poseidon and Caeneus: a case of pubertal gender inversion in Greek mythology.

Disorders of sex development (DSDs) are very frequently encountered in ancient Greek mythology. One of the most striking types of DSD described in many myths is gender transformation wherein a female becomes a male or vice versa. Herein, we present via the marvelous myth of Poseidon and Caeneus a case of pubertal gender inversion. A medical interpretation of the myth whereby we attempt to form a diagnosis of this case of DSD is also presented.

Placental mRNA Expression of Neurokinin B Is Increased in PCOS Pregnancies with Female Offspring.

Current research suggests that polycystic ovary syndrome (PCOS) might originate in utero and implicates the placenta in its pathogenesis. Kisspeptin (KISS1) and neurokinin B (NKB) are produced by the placenta in high amounts, and they have been implicated in several pregnancy complications associated with placental dysfunction. However, their placental expression has not been studied in PCOS. We isolated mRNA after delivery from the placentae of 31 PCOS and 37 control women with term, uncomplicated, singleton pregnancies. The expression of KISS1, NKB, and neurokinin receptors 1, 2, and 3 was analyzed with real-time polymerase chain reaction, using ß-actin as the reference gene. Maternal serum and umbilical cord levels of total testosterone, sex hormone-binding globulin (SHBG), free androgen index (FAI), androstenedione, dehydroepiandrosterone sulfate (DHEAS), Anti-Mullerian hormone (AMH), and estradiol were also assessed. NKB placental mRNA expression was higher in PCOS women versus controls in pregnancies with female offspring. NKB expression depended on fetal gender, being higher in pregnancies with male fetuses, regardless of PCOS. NKB was positively correlated with umbilical cord FAI and AMH, and KISS1 was positively correlated with cord testosterone and FAI; there was also a strong positive correlation between NKB and KISS1 expression. Women with PCOS had higher serum AMH and FAI and lower SHBG than controls. Our findings indicate that NKB might be involved in the PCOS-related placental dysfunction and warrant further investigation. Studies assessing the placental expression of NKB should take fetal gender into consideration.

Diet, physical exercise and Orlistat administration increase serum anti-Müllerian hormone (AMH) levels in women with polycystic ovary syndrome (PCOS).

The present study investigates the combined effect of diet, physical exercise and Orlistat for 24 weeks, on serum anti-Müllerian hormone (AMH) levels in overweight and obese women with polycystic ovary syndrome (PCOS) and in overweight and obese controls. Sixty-one (61) selected women with PCOS and 20 overweight and obese controls followed an energy-restricted diet, physical exercise plus Orlistat administration (120 mg, 3 times per day) for 24 weeks. At baseline, week 12 and week 24, serum levels of AMH, FSH, LH, PRL, androgens, sex hormone-binding globulin (SHBG), glucose, and insulin were measured and Free Androgen Index (FAI) and Insulin Resistance (IR) indices were calculated. In PCOS women, serum AMH levels increased after 12 and 24 weeks of treatment. After 12 weeks LH and SHBG were increased, while Testosterone decreased. After 12 and 24 weeks, FAI was decreased and all indices of IR were significantly improved. We concluded that in overweight and obese women with PCOS Orlistat administration, combined with diet and physical exercise, for 24 weeks, resulted in significant weight loss, improvement of hyperandrogenism and insulin sensitivity, and increased serum AMH levels.

Heterozygous mutations in SOX2 may cause idiopathic hypogonadotropic hypogonadism via dominant-negative mechanisms.

Pathogenic SRY-box transcription factor 2 (SOX2) variants typically cause severe ocular defects within a SOX2 disorder spectrum that includes hypogonadotropic hypogonadism. We examined exome-sequencing data from a large, well-phenotyped cohort of patients with idiopathic hypogonadotropic hypogonadism (IHH) for pathogenic SOX2 variants to investigate the underlying pathogenic SOX2 spectrum and its associated phenotypes. We identified 8 IHH individuals harboring heterozygous pathogenic SOX2 variants with variable ocular phenotypes. These variant proteins were tested in vitro to determine whether a causal relationship between IHH and SOX2 exists. We found that Sox2 was highly expressed in the hypothalamus of adult mice and colocalized with kisspeptin 1 (KISS1) expression in the anteroventral periventricular nucleus of adult female mice. In vitro, shRNA suppression of mouse SOX2 protein in Kiss-expressing cell lines increased the levels of human kisspeptin luciferase (hKiss-luc) transcription, while SOX2 overexpression repressed hKiss-luc transcription. Further, 4 of the identified SOX2 variants prevented this SOX2-mediated repression of hKiss-luc. Together, these data suggest that pathogenic SOX2 variants contribute to both anosmic and normosmic forms of IHH, attesting to hypothalamic defects in the SOX2 disorder spectrum. Our study describes potentially novel mechanisms contributing to SOX2-related disease and highlights the necessity of SOX2 screening in IHH genetic evaluation irrespective of associated ocular defects.

Association of estrogen receptor alpha (ERα) gene polymorphisms with endometrial thickness and lipid profile in women with breast cancer treated with aromatase inhibitors.

Aromatase inhibitors (AIs) provide an alternative to tamoxifen as an adjuvant therapy for post-menopausal, hormone-receptor positive breast cancer patients. The aim of the present study was to evaluate the effect of PvuII and XbaI polymorphisms of the ERα gene at ΑΙs treatment's adverse effects in post-menopausal women with breast cancer. The study included 87 post-menopausal women with ER-positive breast cancer treated with AIs and 80 healthy controls. The overall presence of ERα polymorphisms in all women with breast cancer was not different from the healthy controls. Endometrial thickness under AIs treatment was reduced from (mean value ± SD) 6,404 ± 2,901 mm to 3,666 ± 1,4656 mm. Moreover, the AA XbaI genotype was associated with greater reduction in endometrial thickness during therapy with AIs (p = 0.005). The presence of the CC PvuII and the AA XbaI genotypes were associated with elevated LDL levels and elevated triglycerides. In conclusion, the results of the present study showed that the genotype of women with breast cancer under AIs treatment might influence treatment's adverse effects, as, the presence of the CC PvuII and the AA XbaI genotypes of the ERα were associated with elevated LDL and triglycerides serum levels, while the AA XbaI genotype was associated with a greater reduction in endometrial thickness.

Final height in elite male artistic gymnasts.

OBJECTIVE: Elite male artistic gymnasts (AG) are exposed to high levels of physical and psychological stress during adolescence and experience a significant late maturation in both linear growth and pubertal development. The aim of the present study was to determine the impact of intensive physical training on the adult final height in elite male AG. METHODS: This study is unique in character, as all variables were measured on the field of competition. The study was prospective and longitudinal; however, the current analysis of data is cross-sectional. Data from 86 elite male AG were obtained during the gymnastics competitions of European and World Championships. Clinical evaluation included height and weight measurements, as well as assessment of pubic hair and genital development according to Tanner's stages of pubertal development. The laboratory investigation included determination of skeletal maturation. All athletes completed a questionnaire that included questions on personal (onset and intensity of training, number of competitions per year) and family data (paternal and maternal heights). RESULTS: Male AG were below the 50th percentile for both final height and weight. Elite male AG had final height standard deviation score (SDS) lower than their genetic predisposition. Final height SDS was correlated positively with target height SDS (r = 0.430, p < 0.001) and weight SDS (r = 0.477, p < 0.001) and negatively to the intensity of training (r = -0.252, p = 0.022). The main factors influencing final height, by multiple regression analysis were weight SDS (p < 0.001) and target height SDS (p = 0.003). CONCLUSION: In elite maleAG, final height falls short of genetic predisposition, still well within normal limits. Considering medical and psychological risks in general, and based on the results of this research project, the International Federation of Gymnastics has increased the age limit for participants in international gymnastics competitions by 1 year.

Endocrine disruptors in ancient times and Greek mythology: the spring of Salmacis and the curse of Hermaphroditus.

According to Greek mythology, the spring waters of Salmacis (or Salmakis) feminized the god Hermaphroditus (or Hermaphroditos) and transformed his nature from male to half-male and half-female. The mythical properties of these waters are described in the writings of authors and philosophers of the Hellenistic period. It is evident that the spring of Salmacis and lake actually existed (located in Halicarnassus, today Bodrum, Turkey) and are not the product of poetic imagination. Hence, it could be hypothesized that there were certain natural elements in the waters that had a feminizing effect on the male reproductive axis. We now know, in fact, that naturally occurring environmental agents, also known as endocrine disruptors, can affect the endocrine and reproductive function of both males and females. However, since most endocrine disruptors today are manmade products of the modern industrial lifestyle, the presence and effect of naturally occurring disruptors in times preceding the Industrial Revolution are not widely discussed. It is thus against this background that we seek to formulate a differential diagnosis of male feminization attributable to the effect of natural environmental factors in the form of endocrine disruptors that will have existed in environments round the globe since time immemorial. We conclude that if there had been an accumulation of the mycotoxin zearalenone (ZEA) in the waters of Salmacis, chronic exposure to the lake's water could have resulted in the phenotypic changes described in the Salmacis myth.

Expression stability of ACTB, 18S, and GAPDH in human placental tissues from subjects with PCOS and controls: GAPDH expression is increased in PCOS.

PURPOSE: The aim was to assess the expression stability of three commonly used reference genes, namely, ß-actin (ACTB), 18S ribosomal RNA (18S), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH), in placental tissue obtained from pregnant women with polycystic ovary syndrome (PCOS) and healthy controls. METHODS: mRNA was isolated after delivery from the placentae of 10 PCOS and 10 control women with term, uncomplicated, singleton pregnancies. The expression of ACTB, 18S, and GAPDH was analyzed using real-time polymerase chain reaction (RT-PCR). Gene expression stability was evaluated with the RefFinder, GeNorm, Normfinder, BestKeeper, and Delta-Ct tools. RESULTS: ACTB was ranked as the most stably expressed gene, followed by 18S. The expression of GAPDH varied considerably in both studied groups, while it was increased in PCOS versus controls (5.3-fold, p < 0.05). CONCLUSIONS: ACTB is an appropriate reference gene for placental gene expression studies in women with PCOS, whereas GAPDH is unfit for such a role, as its placental expression is increased in PCOS.

Differences in thyroid function tests after administration of a single supraphysiological dose of ACTH or a high dose of a synthetic steroid.

OBJECTIVE: Although the suppressive action of synthetic steroids on the hypothalamus-pituitary-thyroid (HPT) axis is established, little is known regarding the effect of the administration of synthetic adrenocorticotropic hormone (ACTH). DESIGN: In the context of a randomized, open label, comparative study assessing the efficacy and safety of ACTH and betamethasone in the treatment of hospitalized patients with acute gout, we compared the effects of these agents on thyroid function tests. METHODS: Serum TSH, total T4 and T3 and cortisol were measured before and at 24 and 48 h after a single intramuscular dose of synthetic ACTH (1 mg) or betamethasone (6 mg), in 38 hospitalized patients with acute gout and normal thyroid function. RESULTS: The final analysis included 32 patients, due to missing data. The ACTH and betamethasone groups did not differ regarding the mean age, gender, severity of gout attack, and baseline thyroid parameters. In the ACTH group TSH and T4 were significantly decreased at 24 and at 48 h compared to baseline, while T3 was decreased at 24 but not at 48 h. In the betamethasone group T3 remained stable; TSH and T4 decreased significantly from baseline levels at 24 h; at 48 h, TSH had returned to and T4 showed a partial rebound towards pre-treatment values. CONCLUSIONS: A single IM administration of 1 mg of synthetic ACTH has more profound and prolonged effects on the HPT axis, lasting for at least 48 h, compared to a single IM dose of 6 mg betamethasone.

Teenage pregnancies in Western Greece: experience from a university hospital setting.

PURPOSE: Teenage pregnancies have consistently been associated with preterm labor in a wide range of studies. Evidence regarding the incidence and potential complications of teenage pregnancies in Greece is at present scarce. The aim of this study was to evaluate the perinatal outcomes as well as the risk of perinatal and obstetric complications of teenage pregnancies. METHODS: This retrospective study was conducted at the Department of Obstetrics and Gynecology of the University Hospital of Patras, Greece, and all data recorded concerned the year 2019 (January-December). We retrospectively reviewed 643 cases of singleton pregnancies divided into two groups, as follows: Group A included women of average maternal age (AMA) (20-34 years old), and Group B included teenagers, defined as women less than 20 years old. Data regarding demographic and pregnancy characteristics as well as obstetric and neonatal complications were collected. RESULTS: Teenage pregnancies accounted for 6.7% of all deliveries. We detected significantly higher rates of preterm births (p = 0.025), primiparity (p < 0.001), and negative marital status (p < 0.001) in teenage mothers compared to pregnant women of AMA. There were no significant differences concerning other factors between the two groups. CONCLUSIONS: The findings of the present study raise concern regarding the perinatal, obstetric, and social consequences of teenage pregnancies in Greece. Extended studies that will include further information on antenatal care and detailed socioeconomic factors (i.e., level of education, income, and ethnicity) are required to formulate reliable conclusions concerning teenage pregnancies and their effect on maternal and neonatal health.

Shifting gears: Study of immune system parameters of male habitual marathon runners.

Aim: Marathon is a running event in which athletes must cover a distance of 42.195 km. In addition to participating in marathons, marathoners have incorporated extensive running into their lifestyle. In the present study, we investigated the effect of long-term strenuous exercise in the form of marathon running on the immune system. Methods & Results: We collected peripheral blood samples from 37 male marathoners before/after a race and 37 age/sex/body mass index (BMI)-matched healthy sedentary controls. Hematological and biochemical tests revealed race-induced leukocytosis attributable to neutrophilia and significant increases in plasma lactate dehydrogenase (LDH), creatine phosphokinase (CPK), and cortisol concentrations. Phenotypic analysis of lymphocytes revealed race-induced significant decrease in the number of lymphocytes, memory helper T (Th) cells, naive, memory and activated cytotoxic T (Tc) cells, natural killer (NK), NKT, and B1 cells, and a significant increase in the number of activated Th and regulatory Th cells (Tregs). Compared with controls, marathoners maintained significantly lower levels of memory and activated Th cells and higher levels of activated Tc and B1 cells. Measurement of plasma cytokine levels revealed a pro-inflammatory cytokine polarization that increased after the race. Examination of gene expression of cytokines and Th-cell signature transcription factors in peripheral blood mononuclear cells revealed a significant decrease in tumor necrosis factor α (TNF-α) and interleukin (IL)-17, and a significant increase in IL-6, IL-10 and forkhead box P3 (FoxP3) after the race. Compared with controls, marathoners maintained significantly higher levels of TNF-α. Assessment of the suppressive capacity of Tregs in co-cultures of isolated effector Th cells and Tregs showed significantly increased suppressive capacity of marathoners' Tregs after the race. Conclusions: Compared with controls, marathoners live with permanent changes in certain immune parameters. Marathoners exhibit a stable pro-inflammatory cytokine polarization that increases after the race and is counterbalanced by increased numbers of Tregs overexpressing FoxP3 and having increased suppressive capacity.

The impact of oral contraceptives and metformin on anti-Müllerian hormone serum levels in women with polycystic ovary syndrome and biochemical hyperandrogenemia.

OBJECTIVE: To assess the impact of metformin and of two different oral contraceptives (OCs) containing cyproterone acetate and drospirenone, on serum anti-Müllerian hormone (AMH) levels, in a cohort of women with polycystic ovary syndrome (PCOS) with hyperandrogenism. DESIGN: Prospective randomised study. SETTING: Division of Endocrinology and Human Reproduction, Aristotle University of Thessaloniki. PATIENTS: Forty-five (45) women with PCOS diagnosed according to the criteria proposed in 1990 by the NIH. INTERVENTIONS: Women with PCOS were randomised into three groups, all treated for 6 months: Group A received an OC containing 35 µg ethinylestradiol plus 2 mg cyproterone acetate, Group B received an OC containing 30 µg ethinylestradiol plus 3 mg drospirenone and Group C received metformin 850 mg × 2. Main outcome measure(s). Anti-Müllerian hormone levels were measured by a specific ELISA. RESULTS: AMH was significantly decreased under treatment with 35 µg ethinylestradiol plus 2 mg cyproterone acetate (p = 0.002 at 3 months and p < 0.001 at 6 months). Treatment with 30 µg ethinylestradiol plus 3 mg drospirenone, and treatment with metformin 850 mg × 2 did not significantly affect serum AMH levels. AMH was significantly decreased under OCs treatment compared to metformin 850 mg × 2 (p = 0.005). CONCLUSION(S): AMH serum levels were significantly decreased under treatment with 35 µg ethinylestradiol plus 2 mg cyproterone acetate, due to decrease in androgens and suppression of gonadotropins.

Increased plasma viscosity in young women with polycystic ovary syndrome using an oral contraceptive containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate.

OBJECTIVES: To investigate the influence of 6 months of treatment with an oral contraceptive (OC) containing 35 µ g ethinyl estradiol and 2 mg cyproterone acetate on plasma viscosity (PV) in young women with polycystic ovary syndrome (PCOS). DESIGN: Patients with PCOS were assessed for PV before and after 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate. PV was determined by a viscometer Type 53610/I SCHOTT-Instruments, Mainz at 37°C. SETTINGS: Subjects were recruited from the Department of Obstetrics and Gynaecology, Division of Reproductive Endocrinology at the University Hospital of Patras, Greece. PATIENTS: The study included 66 young women with PCOS. MAIN OUTCOME MEASURES: PV. RESULTS: In PCOS women as a whole, PV at baseline was 1.249 ± 0.049 mm(2)/s (n = 66). After 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate, PV was increased to 1.268 ± 0.065 mm(2)/s (p = 0.038). The difference between PV before and after 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate (Δviscosity) was 0.01864 ± 0.071452 mm(2)/s. ΔViscosity was related to ?fibrinogen (r = 0.270, p = 0.046), to Δhematocrit (r = 0.514, p = 0.09) and to Δtriglycerides (r = 0.292, p = 0.021). CONCLUSION: Young women with PCOS presented an increased PV under OC treatment with 35 µg ethinyl estradiol and 2 mg cyproterone acetate.

Leucippus, either male or death: a case of sex reversal by divine intervention.

The concept of metamorphosis (change of form, structure, or substance) is very frequently encountered in Ancient Greek and Roman literature. One of the most striking types of metamorphosis described in many myths is gender transformation, where a man becomes a woman or vice versa. Herein, we present a case of pubertal gender inversion, the marvelous story of the Cretan Leucippus, which not only inspired many ancient writers but also led to the development of a distinct, local, religious cult. A medical interpretation of the myth, whereby we attempt to establish a diagnosis for this case of heterosexual puberty, is also provided.

A manless adultery: the story of Bassa as related in a Marcus Valerius Martialis' epigram.

During the Golden Age of the Roman Empire, Rome was transformed into a magnificent city where architecture, the arts, and commerce flourished. An inconceivable amount of wealth was accumulated by a handful of noble families, while the masses starved. In such a context, moral values inevitably decline, while sexual mores are liberalized and ever more veer towards salacity. This reality was elegantly illustrated in short, often sarcastic poems known as epigrams. Herein, we present a case of a woman with enigmatic appearance of the external genitalia, exhibiting unrestrained homosexual activity, as described in an epigram by Marcus Valerius Martialis (a contemporary poet who lived in the 1st century AD). Based on the information provided in the ancient text, we formulate a differential diagnosis and deduce that this woman was, in fact, a case of congenital adrenal hyperplasia (CAH). To our knowledge, this is the earliest literary description worldwide of a case of CAH as a cause of homosexuality and unquenchable lust.

No association of the G972S polymorphism of the insulin receptor substrate-1 gene with polycystic ovary syndrome in lean PCOS women with biochemical hyperandrogenemia.

PURPOSE: The aim of the present study was to determine the prevalence and association of the G972S polymorphism of the insulin receptor substrate-1 gene (IRS-1 G972S SNP) with polycystic ovary syndrome (PCOS) and insulin resistance-related traits in a distinct phenotypic group of lean PCOS women with biochemical hyperandrogenemia, excluding obesity, which is considered to be an aggravating parameter of insulin resistance. METHODS: The study included 162 women with PCOS and 122 regularly menstruating, ovulatory women as controls. Physical measurements included weight, height, fat-free mass, fat mass, systolic and diastolic blood pressure and resting heart rate. Biochemical parameters included the serum testosterone, free testosterone, androstenedione, total cholesterol, triglycerides, HDL and LDL cholesterol and glucose levels. Insulin resistance was assessed by determining fasting insulin levels, fasting glucose levels, the fasting glucose/insulin ratio, as well as the HOMA and QUICKI indexes. All DNA samples were genotyped by a PCR-restriction fragment length polymorphism (RLFP) assay. RESULTS: No association of the genotype frequencies of the G972S polymorphism in insulin receptor substrate-1 gene (IRS-1 G972S SNP) with PCOS phenotype and insulin resistance was detected. CONCLUSION: The G972S polymorphism of the IRS-1 gene should not be viewed as major contributor to the development of PCOS or as a causative variant for insulin resistance.

Nonalcoholic fatty liver disease in women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) affects 6-15% of women of reproductive age. Nonalcoholic fatty liver disease (NAFLD) affects 25-30% of the general population and its prevalence increases in parallel with the epidemics of obesity and type 2 diabetes mellitus. A growing body of evidence suggests that NAFLD and PCOS quite often co-exist. The aim of this article is to summarize and critically appraise the literature regarding: (1) the rates of co-existence of the two entities, (2) the possible pathophysiological links, (3) the proper diagnostic assessment and (4) the appropriate management of women with NAFLD and PCOS. Data from clinical studies and meta-analyses indicate a higher prevalence of NAFLD in women with PCOS ranging from 34% to 70% compared with 14% to 34% in healthy women. Inversely, women with NAFLD are more often diagnosed with PCOS. Insulin resistance (IR) and hyperandrogenism are two main potential pathophysiological links between the two entities. In this regard, IR seems to interplay with obesity and hyperandrogenism, thus affecting NAFLD and PCOS and being affected by them. Women with PCOS, particularly those with IR and/or hyperandrogenism, are suggested to be screened for NAFLD, while premenopausal women with NAFLD is suggested to be screened for PCOS. Lifestyle recommendations with a change in dietary habits, weight loss and exercise, constitute currently the cornerstone of the management of both NAFLD and PCOS. Insulin sensitizers maybe used for the treatment of these women, while there are limited promising data for the use of liraglutide.
