RESUMEN

Background & objectives: Drospirenone (DRSP) is a progestin with antimineralocorticoid and anti-androgenic activity. When administered in combination with estradiol (E2), it relieves menopausal symptoms. The aim of this study was to evaluate the effects of DRSP/E2 on the reduction of cardiovascular risk factors in menopausal women with hypertension. Methods: A retrospective study was conducted at the Clinical Center of Serbia. The participants were 64 menopausal women [mean age=49.19±4.62 yr, mean body mass index (BMI)=25.08±2.94 kg/m2, mean amenorrhoeic period=2.48±2.46 yr]. The effects of DRSP 2 mg/E2 1 mg on 24 h blood pressure (BP) variability, heart rate (HR), anthropometric characteristics and hormone and lipid levels were evaluated in early menopausal women with previously untreated stage 1 hypertension. All analyses were carried out before and after six and 12 months of therapy. Results: DRSP/E2 significantly reduced daytime BP values during six and 12 months of therapy. The reductions in systolic and diastolic BPs ranged from about -4.50 to -8.50 and from -4.00 to -5.00 mmHg, respectively. There were no significant changes in nocturnal 24 h BPs. DRSP/E2 significantly reduced HR daytime and night-time during the follow up period. DRSP/E2 significantly lowered the BMI, concentrations of total cholesterol, low-density lipoprotein cholesterol and apolipoprotein B, while high-density lipoprotein cholesterol and apolipoprotein concentration increased. Interpretation & conclusions: Continuous long-term therapy with DRSP 2 mg/E2 1 mg significantly lowered 24 h systolic and diastolic BPs and reduced the risk of cardiovascular disease in early menopausal women with stage 1 hypertension. Timely initiated menopausal hormone therapy can have beneficial effects on BP and can reduce the incidence of cardiovascular disease in menopausal women.

RESUMEN

Premature ovarian insufficiency (POI) is a delicate medical problem in young women. This condition is not unchangeable and permanent but is associated with intermittent and unpredictable ovarian activity, resulting in low conception rate. Over the period of 8 years, the evaluation of secondary amenorrhea was conducted in 90 patients below the age of 40 who wished to restore fertility. Having confirmed the diagnosis and investigated the etiology of POI, hormone replacement therapy was applied (sequential administration of estradiol and norethisterone acetate) in the first 30 patients (group A). Estrogen-progestogen therapy with daily supplementation of 25 mg of micronized oral dehydroepiandrosterone (DHEA) was conducted in 44 patients (group B), whereas a combined regime (estrogen-progestogen therapy, DHEA supplementation in daily dose of 25 mg, and melatonin supplementation in daily dose of 3 mg) was conducted in 16 patients (group C). In the course of our study, 16 pregnancies were realized (18% of all cases: 17% in group A; 18% in group B; 19% in group C) 6 to 20 months after the initiation of hormone therapy, and there have been 13 completed term pregnancies so far with normal fetal growth and development. We concluded that estrogen-progestogen therapy combined with DHEA and melatonin could optimize fertility and lead to successful pregnancy in POI patients.

RESUMEN

Aim: to test effects of estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg in treatment of normal weight menopausal women with typical menopausal symptoms, hyperinsulinism, and grade I hypertension.Material and methods: The participants were 133 menopausal women, mean age 51.82 ± 3.25 years, body mass index (BMI) 24.9 ± 2.6 kg/m2, waist/hip 0.80 ± 0.05, amenorrhoeic period 2.12 ± 2.10 years. All patients were treated with E2 1 mg and DRSP 2 mg during 12 months period. Blood samples were taken at 8 am before and during 12 months of therapy for: glycemia, lipids, hormonal analysis, follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, testosterone (T), prolactin (PRL), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG). Oral glucose tolerance test (OGTT) was performed with 75 g glucose in order to assess insulin secretion. All had grade I hypertension 24 h blood pressure monitoring was performed before and after 12 months of therapy.Results: E2/DRSP significantly decreased total cholesterol, low-density lipoprotein (LDL), apolipoprotein B (ApoB), and increased high-density lipoprotein cholesterol (HDL) and apolipoprotein A (ApoA). Insulin area under the curve (AUC) significantly decreased (6586.1 ± 4194.2 vs. 5315.3 ± 2895.0, p < .05) and homeostatic model assessment (HOMA) (3.53 ± 2.18 vs. 3.0 ± 1.8, p < .05). FSH, LH decreased, E2 increased significantly. Of 24 h day blood pressure decreased significantly.Conclusions: E2/DRSP represents suitable therapy for hyperinsulinemic, grade I hypertensive menopausal women with typical symptoms and normal weight.

RESUMEN

OBJECTIVE: A high prevalence of insulin resistance (IR) has proven to manifest in patients with adrenal incidentalomas (AI). It has been demonstrated that an increase in IR is related to the size of tumourous masses; additionally, luteinizing hormone (LH)-dependent adrenal pathologies are well documented in patients with LH-responsive adrenal tumours occurring under conditions of physiologically elevated LH. We hypothesized that an association between LH and insulin might play a role in adrenal tumourigenesis and steroidogenesis. DESIGN: The aim of our study was to investigate the association between LH and IR; adrenal tumour size (ATS) and IR; LH and cortisol after the 1 mg overnight dexamethasone test (1 mg DST); and ATS and 1 mg DST cortisol in AI patients. This was a case-control study conducted in the Clinic for Endocrinology, Diabetes and Metabolic Diseases in Belgrade, Serbia. The total study group consisted of 105 menopausal women: 75 AI patients [27 with nonfunctional AI (NAI) and 48 with (possible) autonomous cortisol secretion ((P)ACS)] and 30 age-, BMI-, LH- and menopause duration-matched healthy control (HC) women. To estimate IR, we used homeostasis model assessment (HOMA-IR). RESULTS: Luteinizing hormone and ATS are in a significant positive correlation with HOMA-IR and 1 mg DST cortisol in menopausal patients with AI and (P)ACS. CONCLUSIONS: Our data point to a possible cause-effect relationship between LH and insulin in patients with AI and (P)ACS adding to the body of evidence of their involvement in adrenal tumourigenesis and steroidogenesis.

RESUMEN

RATIONALE: The present work is devoted to the structural elucidation of by-products issued from the direct ultraviolet-visible (UV-vis) irradiation of dehydroacetic acid (DHA) in solution and in cosmetic emulsion. METHODS: Analyses were carried out using gas chromatography coupled with ion trap mass spectrometry and by high-performance liquid chromatography coupled with ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (LC/UHRMS). The potential toxicities of by-products were estimated by in silico calculations based on a QSAR (Quantitative Structure-Activity Relationship) approach and by in vitro bioassays conducted on Vibrio fischeri bacteria. RESULTS: Three photoproducts were detected by LC/MS while one photoproduct was detected by GC/MS. The first photoproduct (PP1) corresponds to an isomer of DHA while two isomeric compounds correspond to dimeric structures. The oral rat LD50 of PP1 was evaluated to be 4.5 times lower than that of the parent molecule which classes it in the category 'moderately toxic' on the Hodge and Sterne toxicity classification. In vitro assays on Vibrio fischeri bacteria showed that the global ecotoxicity of the DHA solution increases with irradiation time. CONCLUSIONS: With the exception of one photoproduct, the structures proposed for the photoproducts on the basis of mass spectral interpretation have not been reported in previous studies. All photoproducts, with the exception of dimers, were detected after irradiation in the cosmetic emulsion. This result shows that personal care products containing DHA must be protected from direct sunlight to prevent photodegradation.

RESUMEN

More empathized approach is required and is obligatory to women with premature ovarian insufficiency (POI) interested for pregnancy. In order to improve fertility rate in POI patients our suggestions would be: (1) To decrease FSH value to 10-15 IU/L by increasing estrogen. Oocyte donation can be suggested after a minimum of six month interval from FSH between 10-15 IU/L and when no dominant follicles are found. (2) To perform oral glucose tolerance test (OGTT). Insulin sensitizing agents has to be included, when indicated, 3-6 month before pregnancy. (3) TSH has to be 1-2.5 mM/L during 3-6 months before pregnancy. (4) Tests for thrombophyllia (Leiden V, FII, MTHFR, PAI) have to be obligatory. They are less expensive than those repeated in vitro fertilizations. Therapy has to be included according to the indications. (5) In order to regulate disturbed immune response in POI patients with endometriosis oral contraceptive therapy is needed for atleast six months prior to the pregnancy. (5) Encourage the patients and advice them about healthy life style and eating habits. (6) Add other drugs, when they are indicated. Complex interplay between endocrine, immunological, haematological, and psychological factors are very often underdetected in POI patients. It is very important to find out the real time for oocyte donation after correcting all the disturbances, improving endometrium receptivity and reaching women's acceptable psychological status. Untreated disturbances induce cardiovascular diseases, diabetes mellitus, thyroid diseases, coagulopathioes etc.

RESUMEN

- The aim of the study was to assess the role of the estradiol and progesterone relationship during the late luteal phase and the occurrence of fibrocystic breast disease (FBD). The concentration of estradiol/progesterone was measured in the group of women with FBD as study group (n=50) and control group of women without FBD (n=40). All women had regular ovulation cycles. Blood samples for estradiol (E2), progesterone (P) and prolactin determination were obtained in the morning at 8 am on days 21 and 24 of menstrual cycle. Significant mastalgia and mastodynia history in women with FBD was obtained with yes or no questionnaire. FBD diagnosis was confirmed with ultrasound (size and number of simple cysts). In the control group, a reduced E2/P ratio was noticed from day 21 to day 24 of the cycle (from 14.8±11.5 pg/mL to 9.1±6.1 pg/mL; p<0.05), which was not recorded in the group of women with FBD (study group). Even the slightest disturbance of the E2/P ratio may contribute to the occurrence of FBD with clinical manifestations of mastalgia and mastodynia.

RESUMEN

OBJECTIVE: To assess influence of obesity and hormone disturbances on sexuality in the menopause. METHODS: The study included 73 menopausal women, who were divided into groups according to body mass index (BMI) ≥ 26.7 kg/m2. Anthropometric characteristics and blood pressure were measured. Blood was taken at 08:00 for hormones. All the participants filled in McCoy Female Sexual Questionnaire for the assessment of sexual life. STATISTICS: Student's t-test, correlation, analysis of variance (ANOVA). RESULTS: Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and sex hormone-binding globulin (SHBG) were very significantly lower in obese compared to controls. E2 and systolic blood pressure were very significantly, while diastolic blood pressure significantly higher in obese compared to controls. Obese women had significantly decreased frequency of pain during sexual intercourse (3.48 ± 2.64 vs. 4.09 ± 2.81). Influence of age on frequency of sexual intercourse was very significant. Significant influence in interaction between BMI and age on frequency of sexual fantasies as well as significant influence of BMI on satisfaction with partner as lover is also found. CONCLUSION: Obesity has influence on different aspects of sexuality in the postmenopausal women. Our results suggest the need of awareness toward obesity and its impact on sexuality in the menopause.

RESUMEN

Primary premature ovarian insufficiency (PPOI) is characterized by hypergonadotropic amenorrhea and hypoestrogenism in women under 40 years of age. PPOI incidence is 1:10,000 in women aged 18-25, 1:1000 in women aged 25-30 and 1:100 in women aged 35-40. In 10%-28% of cases, PPOI causes primary and in 4%-18% secondary amenorrhea. The process is a consequence of accelerated oocyte atresia, diminished number of germinated cells, and central nervous system aging. Specific genes are responsible for the control of oocyte number undergoing the ovulation process and the time to cessation of the reproductive function. A positive family history of PPOI is found in 15% of women with PPOI, indicating the existing genetic etiology. Primary POI comprises genetic aberrations linked to chromosome X (monosomy, trisomy, translocation, deletion) or to autosomal chromosome. Secondary POI implies surgical removal of ovaries, chemotherapy and radiotherapy, and infections. Diagnostic criteria include follicle stimulating hormone level >40 IU/L and estradiol level <50 pmol/L.

RESUMEN

BACKGROUND AND AIMS: There have been few studies in the area of Self-Perception in transsexual persons, except for the population of transsexual adolescents. Bearing in mind its importance not only in the assessment of personality but also in predicting adaptive capacity, the goal of our research is based on the examination of Self-Perception of adult transsexual persons. METHOD: The study was conducted using a Rorschach test, which provides an insight into various aspects of Self-Perception. The sample consisted of 15 transsexual persons, who passed the standard diagnostic procedure. RESULTS: The results suggest that transsexual persons manage to maintain Adequate Self-Esteem. Hypervigilance Index and Obsessive Style Index are negative, while the values showing a negative quality of Self-Regard and the capacity for introspection tend to increase. In the process of Self-Introspection, negative and painful emotional states are often perceived. CONCLUSION: The estimation of Self-Perception in adult transsexual persons indicates a trend of subjective perception of a personal imperfection or inadequacy. This is probably the result of experiencing discomfort for a number of years due to gender incongruence and dysphoria, in particular in persons who enter the sex reassignment procedure later in their adulthood.

RESUMEN

Transsexualism is a complex condition in which the person experiences the inconsistency between the desired gender and their biological gender. Absence of the vagina is devastating in male to female transsexuals. Creation of the neovagina is the main surgical problem in these patients. Historically, beginnings of the neovaginal creation have their roots in the treatment of Mayer-Rokitansky syndrome and conditions such as cloacal anomalies, certain intersex disorders, vaginal malignancies, or severe vaginal trauma, but have more recently found great purpose in male to female sex reassignment surgery. Many operative procedures have been described but none is ideal. Therefore, the search for new, improved solutions continues. In neovaginoplasty reconstruction of the vulvovaginal complex is performed in its entity. The gold standard in neovaginal reconstruction in male to female sex reassignment surgery is penile skin inversion technique with or without scrotal flaps, which enables adequate sensation of the neovagina, good neovaginal depth, good erotic sensitivity of the neclitoris, and esthetically acceptable labia minora and maiora.

RESUMEN

BACKGROUND: Investigations in the field of gender identity disorder (GID) have been mostly related to psychiatric comorbidity and severe psychiatric disorders, but have focused less on personality and personality disorders (PDs). AIMS: The aim of the study was to assess the presence of PDs in persons with GID as compared to cisgendered (a cisgender person is a person who is content to remain the gender they were assigned at birth) heterosexuals, as well as to biological sex. METHODS: The study sample consisted of 30 persons with GID and 30 cisgendered heterosexuals from the general population. The assessment of PDs was conducted by application of the self-administered Structured Clinical Interview for DSM-IV Axis II PDs (SCID-II). RESULTS: Persons with GID compared to cisgender heterosexuals have higher presence of PDs, particularly Paranoid PD, avoidant PDs, and comorbid PDs. In addition, MtF (transwomen are people assigned male at birth who identify as women) persons are characterized by a more severe psychopathological profile. CONCLUSIONS: Assessment of PDs in persons with GID is of great importance as it comprises a key part of personalized treatment plan tailoring, as well as a prognostic factor for sex-reassignment surgery (SRS) outcome.

RESUMEN

Atypical prenatal hormone exposure could be a factor in the development of transsexualism. There is evidence that the 2nd and 4th digit ratio (2D:4D) associates negatively with prenatal testosterone and positively with estrogens. The aim was to assess the difference in 2D:4D between female to male transsexuals (FMT) and male to female transsexuals (MFT) and controls. We examined 42 MFT, 38 FMT, and 45 control males and 48 control females. Precise measurements were made by X-rays at the ventral surface of both hands from the basal crease of the digit to the tip using vernier calliper. Control male and female patients had larger 2D:4D of the right hand when compared to the left hand. Control male's left hand ratio was lower than in control female's left hand. There was no difference in 2D:4D between MFT and control males. MFT showed similar 2D:4D of the right hand with control women indicating possible influencing factor in embryogenesis and consequently finger length changes. FMT showed the lowest 2D:4D of the left hand when compared to the control males and females. Results of our study go in favour of the biological aetiology of transsexualism.

RESUMEN

Previous studies relating to prolonged and fractionated distillation procedures highlighted essential oils' (EOs) chemical composition to be significantly dependent on the extraction duration and harvesting time. As a continuation, a hydrodistillation procedure was applied to ripe fruit material of fennel, Foeniculum vulgare Miller (Apiaceae), collected from three localities in Montenegro (Podgorica, Niksic, and Kotor) to furnish a total of 12 EOs. Liquid and vapor phases of the samples were analyzed by Gas Chromatography/Mass Spectrometry and Headspace-Gas Chromatography/Mass Spectrometry techniques, and 18 compounds have been identified. Although both quantitative and qualitative differences between the samples were notable, the phenylpropanoids anethole (ANE) and estragole and the monoterpenoids α-terpineol (TER) and fenchone (FEN) could be singled out as the most abundant constituents. The EOs from Podgorica belong to the most common ANE-rich chemotype, while the predominance of the monoterpenoid fraction is characteristic of the samples from Niksic and Kotor. The latter is particularly rich in TER (up to 56.5%), with significant amounts of FEN and ANE. This chemical profile could represent a new chemotype of fennel EO. Vapor phases contained mainly monoterpenoids, with increased amounts of FEN and TER, while the number of phenylpropanoids was significantly decreased.

RESUMEN

Background: Disrupted sleep affects cardio-metabolic and reproductive health. Obstructive sleep apnea syndrome represents a major complication of obesity and has been associated with gonadal axis activity changes and lower serum testosterone concentration in men. However, there is no consistent opinion on the effect of obstructive sleep apnea on testosterone levels in men. Objective: The aim of this study was to determine the influence of obstructive sleep apnea on total and free testosterone levels in severely obese men. Materials and methods: The study included 104 severely obese (Body Mass Index (BMI) ≥ 35 kg/m2) men, aged 20 to 60, who underwent anthropometric, blood pressure, fasting plasma glucose, lipid profile, and sex hormone measurements. All participants were subjected to polysomnography. According to apnea-hypopnea index (AHI) patients were divided into 3 groups: <15 (n = 20), 15 - 29.9 (n = 17) and ≥ 30 (n = 67). Results: There was a significant difference between AHI groups in age (29.1 ± 7.2, 43.2 ± 13.2, 45.2 ± 10.2 years; p < 0.001), BMI (42.8 ± 5.9, 43.2 ± 5.9, 47.1 ± 7.8 kg/m2; p = 0.023), the prevalence of metabolic syndrome (MetS) (55%, 82.4%, 83.6%, p = 0.017), continuous metabolic syndrome score (siMS) (4.01 ± 1.21, 3.42 ± 0.80, 3.94 ± 1.81, 4.20 ± 1.07; p = 0.038), total testosterone (TT) (16.6 ± 6.1, 15.2 ± 5.3, 11.3 ± 4.44 nmol/l; p < 0.001) and free testosterone (FT) levels (440.4 ± 160.8, 389.6 ± 162.5, 294.5 ± 107.0 pmol/l; p < 0.001). TT level was in a significant negative correlation with AHI, oxygen desaturation index (ODI), BMI, MetS and siMS. Also, FT was in a significant negative correlation with AHI, ODI, BMI, age, MetS and siMS. The multiple regression analysis revealed that both AHI and ODI were in significant correlation with TT and FT after adjustment for age, BMI, siMS score and MetS components. Conclusion: Obstructive sleep apnea is associated with low TT and FT levels in severely obese men.

RESUMEN

Acetamiprid is a neonicotinoid pesticide, which is extensively used on agricultural crops, but has a high toxic effect on beneficial insects and the human body. It is exposed to sunlight irradiation on crops but also in surface waters where it is found at a high level due to its resistance to common water treatments. The aim of the present work was to study the UV-visible photodegradation of acetamiprid, alone and in two marketed mixtures (Polysect Ultra SL® and Roseclear Ultra®). Ten photoproducts were characterized using LC-HR-MS/MS analysis. Photodegradation pathways were proposed based on the chemical structures of photoproducts and kinetic measurements; a matrix effect has been evidenced for commercial mixtures. Most photoproducts exhibit potential developmental toxicity twice higher than that of the parent compound. Regarding potential mutagenicity, all photoproducts are less toxic than acetamiprid. Estimated oral rat LD50 values show that the potential toxicities of photoproducts are similar or lower than that of acetamiprid. In vitro tests on Vibrio fischeri bacteria showed that the ecotoxicities of marketed mixtures are significantly higher than that of acetamiprid in aqueous solution; they slightly increase after UV-light exposure.

RESUMEN

A growing number of patients with adrenal incidentalomas and subclinical Cushing's syndrome (SCS) led to an increasing number of different guidelines, and diagnostic and treatment recommendations. Excess cortisol secretion in patients with SCS is associated with several comorbidities, such as hypertension, dyslipidemia, type 2 diabetes mellitus, and obesity, which in the long-term increase mortality of these patients. Subtle cortisol secretion affects bone health, quality of life and causes depression, but due to the unapparent clinical features, patients with SCS are often at risk between over and under treatment. This narrative review aimed to summarize the latest recommendations on the approach to the patient with subclinical Cushing's syndrome.

RESUMEN

INTRODUCTION: Gender dysphoria occurs in all societies and cultures. The prevailing social context has a strong impact on its manifestations as well as on applications by individuals with the condition for sex reassignment treatment. AIM: To describe a transsexual population seeking sex reassignment treatment in Serbia, part of former Yugoslavia. METHODS: Data, collated over a period of 20 years, from subjects applying for sex reassignment to the only center in Serbia, were analyzed retrospectively. MAIN OUTCOME MEASURES: Age at the time of application, demographic data, family background, sex ratio, the prevalence of polycystic ovarian syndrome (PCOS) among female-to-male (FTM) transsexuals, and readiness to undergo surgical sex reassignment were tabulated. RESULTS: Applicants for sex reassignment in Serbia are relatively young. The sex ratio is close to 1:1. They often come from single-child families. More than 10% do not wish to undergo surgical sex reassignment. The prevalence of PCOS among FTM transsexuals was higher than in the general population but considerably lower than that reported in the literature from other populations. Of those who had undergone sex reassignment, none expressed regret for their decision. CONCLUSIONS: Although transsexualism is a universal phenomenon, the relatively young age of those applying for sex reassignment and the sex ratio of 1:1 distinguish the population in Serbia from others reported in the literature.

RESUMEN

INTRODUCTION: Metoidioplasty represents one of the variants of phalloplasty in female transsexuals. Its main characteristic is that it is a one-stage procedure. It involves lengthening and straightening of hypertrophied clitoris to create a neophallus, urethral lengthening to enable voiding while standing, and scrotal reconstruction with insertion of testicle prostheses. AIM: Our aim is to describe our technique and highlight its advantages. METHODS: Between September 2002 and April 2007, 82 female transsexuals, aged 18-54 years (mean age 31) underwent one-stage metoidioplasty. Clitoris is lengthened and straightened by division of clitoral ligaments and short urethral plate. Urethroplasty is done with combined buccal mucosa graft and genital skin flaps. Scrotum is created from labia majora in which two testicle prostheses are inserted. Simultaneously, female genitalia are removed. MAIN OUTCOME MEASURES: Patients' personal satisfaction about sensitivity and length of neophallus, possibility to void in standing position, real length of reconstructed urethra as well as complication rate comparing to other published data. RESULTS: The median follow-up was 32 months (range 14-69). The mean neophallic length was 5.7 cm (range 4-10). Voiding in standing position was reported in all patients, while dribbling and spraying were noticed in 23 cases and solved spontaneously. There were two urethral strictures and seven fistulas that required secondary minor revision. All patients reported preserved sensation and normal postoperative erection. Testicle prostheses rejection was not observed in any of the patients. CONCLUSIONS: Metoidioplasty is a single-stage and time-saving procedure. It could be an alternative to total phalloplasty in female transsexuals who do not wish to have sexual intercourse. Also, it represents a first step in cases where additional augmentation phalloplasty is required.
