PCOS (polycystic ovary syndrome) is a common endocrine disorder that affects 8–13% of women of reproductive age. Increased body weight and insulin resistance may be associated with chronic inflammation, which increases the risk of cardiovascular complications. CRP (C-reactive protein) tests may be use to assess persistent inflammation. Elevated CRP levels may be associated with insulin resistance and type 2 diabetes. Determination of hsCRP, highly sensitive C-reactive protein, can be used to assess cardiovascular risk in women with PCOS. In this study, 120 women between the ages of 18 and 42 were divided into two groups: patients with polycystic ovary syndrome (n = 80) and regular menstruating women in whom PCOS was excluded (n = 40). Lipid and carbohydrate metabolism parameters and hsCRP levels were assessed, followed by receiver operating characteristic (ROC) analysis for hsCRP, where metabolic syndrome was the dependent variable. For hsCRP, the cutoff point was 1.44 (mg/dL). Sensitivity for the cutoff point was 0.913 and specificity was 0.691. The area under the curve (AUC) was 0.851 (p < 0.000). The closer the AUC value is to unity, the better the predictive ability of the studied variable. There was also a statistically significant correlation between hsCRP levels and the presence of metabolic syndrome.

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder that affects 8–13% of women of reproductive age. It is one of the most common causes of infertility and is associated with hyperandrogenism in the form of hirsutism and acne, non-ovulatory cycles, and characteristic ovarian morphology. The available research on serum vitamin D deficiency in patients with PCOS and the appropriateness of vitamin D supplementation in this group of women is inconclusive, so we decided to investigate the influence of vitamin D on the incidence of metabolic syndrome and hormonal balance in patients with polycystic ovary syndrome. The study comprised 120 women aged between 18 and 42 years, who were divided into two groups: a group with diagnosed polycystic ovary syndrome (PCOS) and a group of regularly menstruating women without features of androgenisation, in whom polycystic ovary syndrome was excluded. Each patient underwent a history and physical examination, including a gynecological examination, anthropometric measurements were taken, including height, weight, waist, and hip circumference, and blood pressure was measured using the Korotkow method. In the female patients, the following parameters were also determined from the blood: follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestradiol, TSH, ft4, prolactin (PRL), total testosterone, DHEASO4, 17-hydroxyprogesterone (17-OHP), sex-hormone-binding globulin (SHBG), androstendione, 25(OH) vitamin D3 metabolite. The majority of the patients with polycystic ovary syndrome were found to have deficient or suboptimal serum vitamin D levels, and the effects of vitamin D on the SHBG levels and free-androgen indices in these patients was examined. The effects of vitamin D on the incidence of metabolic syndrome and BMI, waist-to-hip ratio, waist circumference, and blood pressure in patients with polycystic ovary syndrome were also found.

Objectives: Available evidence implies that unfavorable changes in the distribution of adipose tissue resulting from hormonal imbalance associated with ovarian insufficiency might influence bone mineral density (BMD). The purpose of our study was to verify if volumes of visceral (VAT), female (FAT) and android (AAT) body fat as determined by densitometry determined influence BMD in women with functional menstrual disorders, and if these correlates some endocrine factors. Material and methods: We examined 293 women (mean age 26.7 ± 4.4 years) who have had psychogenic type of functional hypothalamic secondary amenorrhea for at least three months (mean 5.82 ± 0.94). A variety of hormonal tests, determination of BMD and both distribution and volume of adipose tissue were performed. Results: Volume of adipose tissue in all analyzed body regions indicated a positive correlation with BMD in lumbar spine (VAT: R = 0.277, FAT: R = 0.345, AAT: R = 0.336) and entire skeleton (VAT: R = 0.453, FAT: R = 0.527, AAT: R = 0.529). BMD in both the lumbar spine and entire skeleton had positive correlation with body mass index (R = 0.380 and R = 0.599, respectively) and free androgen index values (R = 0.150 and R = 0.279). It showed a negative correlation with sex hormone-binding globulin (R = –0.191 and R = –0.326). We did not find a parameter that could be an independent predictor of BMD. Conclusions: Distribution of body fat is only one of numerous determinants of BMD in women with functional menstrual disorders and should not be treated as the only predictor for bone mass deficiency. Determination of adipose tissue distribution in these patients has probably minor clinical impact.

A mature teratoma is a germinal neoplasm that differentiates from embryonic multipotent cells into three germ layers. There may also be glandular tissue. The literature describes a total of 658 cases of ovarian neuroendocrine neoplasms, mainly in women over 40 years of age. The authors, together with a systemic review, present a case of a 16-year-old girl diagnosed with and treated for a neuroendocrine tumor. Case description: A 16-year-old girl visited the Paediatric Gynaecology Outpatient Clinic because of abdominal pains that intensified during menstruation. Standard painkillers and diastolic drugs were ineffective. An ultrasound examination revealed a large tumor with a heterogeneous structure in her right ovary. A sparing operation was carried out. During laparotomy, the lesion was enucleated, leaving healthy tissue. Histopathological examination revealed the typical features of teratoma, as well as the coexistence of a G1 neuroendocrine tumor. Immunohistochemical examination (IHC) showed the presence of markers characteristic for this type of tumor. The patient requires constant monitoring in the Endocrinology and Oncological Gynaecology Clinic. Conclusion: Tissue of neuroendocrine neoplasm within a teratoma is rare in this age group of patients; thus, there are currently no standards for long-term follow-up. This case adds to the body of evidence and demonstrates a possible good prognosis with non-aggressive behavior in G1 neuroendocrine tumors and teratomas in young patients.

Hyperandrogenism is the most common endocrine disorder in women, characterized by an imbalance of normal estrogen and androgen levels in the blood. Androgens play an important role in the female body because they influence bone mineral density (BMD), body mass composition, muscle mass, mental state, and the regulation of sexual function. The reduced activity of aromatase, due to mutations in the CYP19A1 gene, reduces the estrogen pool in favor of androgens. Clinically, aromatase deficiency causes hyperandrogenism in women. Therefore, the aim of the study was to assess the effect of the CYP19A1 gene polymorphism on selected markers of bone metabolism and hormonal parameters in women with hyperandrogenism. The study group was comprised of 80 young women with hyperandrogenism who underwent measurements of bone mineral density (BMD), and determination of hormonal and metabolic parameters. Enzyme immunoassays were used to measure leptin, total sRANKL (free and bound RANKL), osteoprotegerin, and total 25-OH Vitamin D. An analysis of the CYP19A1 gene polymorphisms was performed using the real-time PCR method. The GG genotype of the CYP19A1 rs700518 polymorphism turned out to be associated with: FEI (Free Estradiol Index), SHGB concentration, estradiol concentration, and insulin concentration determined in the glucose tolerance test 60’ compared to AG and AA genotypes. Patients with the AG genotype had a higher ratio of android to gynoid fat and a greater content of visceral adipose tissue. Higher visceral tissue content may reduce BMD. In conclusion, the study showed that the CYP19A1 rs700518 polymorphism may be associated with the distribution of adipose tissue in young women with hyperandrogenism. These results suggest that patients with the AG genotype may develop osteoporosis.

Swyer syndrome is a special form of DSD (disorders of sex development), so-called pure gonadal dysgenesis with a karyotype 46, XY and a female phenotype. One of the most important problems in patients with DSD is the risk of gonadal tumors. We present a case of a 26-year-old patient with Swyer syndrome. The patient had primary amenorrhea and no puberty characteristics. In ultrasound imaging in the vicinity of the uterus, there were two homogeneous structures. A genetic diagnosis was also performed, which showed karyotype 46, XY. The patient underwent a bilateral gonadectomy. Histopathological examination revealed the presence of dysgerminoma in both dysgenetic gonads. The follow-up of five years now did not show any changes suspected of invasion. We concluded that the primary amenorrhea, along with the absence of development of sexual characteristics, should prompt an expanded diagnosis for disorders of sex development. Gonadal dysgerminoma should be suspected even in the absence of tumor features on ultrasound and blood laboratory tests. Early prophylactic gonadectomy could protect patients from developing tumors in dysgenetic gonads.

Hyperandrogenism is the most common endocrine disorder in women, characterized by an imbalance in normal estrogen and androgen levels in the blood. Androgens influence bone mineral density, body mass composition, muscle mass, mental state, and the regulation of sexual function.. The aim of the study was to assess the effect of estrogen receptor α gene (ESR1) polymorphisms on selected markers of bone metabolism and hormonal parameters in women with hyperandrogenism. The study group included 80 young women with hyperandrogenism who underwent measurements of bone mineral density (BMD), and determination of hormonal and metabolic parameters. Enzyme immunoassays were used to measure leptin, sRANKL (soluble receptor activator of nuclear factor-kB ligand), osteoprotegerin and 25-OH vitamin D total levels. An analysis of ESR1 gene polymorphisms was performed using the real-time PCR method. A relationship was demonstrated between the concentration of free estradiol (FEI) and the concentration of 17-OH-progesterone, and the ESR1 gene polymorphisms: rs3020314 (p = 0.031, p = 0.026 respectively) and rs1884051 (p = 0.033, p = 0.026 respectively). In conclusion, the ESR gene polymorphisms may be associated with hormonal disturbances in the concentration of estrogens and androgens, in hyperandrogenism in young women which may indirectly affect bone mineral density. However, no statistically significant relationships between the studied polymorphisms and the selected parameters of mineral metabolism have been demonstrated..

Simpson-Golabi-Behmel syndrome (SGBS) is a rare genetic condition and is inherited in an X-linked recessive manner. The disease is caused by a change in the nucleotide sequence of an X-linked gene encoding glypican 3, a protein belonging to the heparan-sulfate membrane proteoglycan family. SGBS case studies are almost entirely restricted to the pediatric population. Scarce literature describing SGBS course in adults may be due to both the high mortality of SGBS patients in childhood and low rate of SGBS diagnosis in adults. We present a case of a 39-year-old man with an initial diagnosis of acromegaly. Genetic tests revealed a hitherto unreported deletion in the GPC3 gene. SGBS manifestations in our patient included tall stature, dysmorphic features, and central nervous system (CNS) anatomical pathology. MRI of the head visualized abnormalities of median line structures, a feature consistent with SGBS: an unclosed craniopharyngeal canal, a sellar-suprasellar cyst, dysmorphic pituitary gland, and a cyst of the septum pellucidum. Moreover, cardiomyopathy complicated by life-threatening paroxysmal ventricular tachycardia was diagnosed. Although various cardiac anomalies are often found in SGBS, their pathogenesis is unclear and may be multifactorial. We believe that the presented case contributes to a better understanding of SGBS and may help clinicians in introducing prophylaxis and treatment for its comorbidities.

The differentiation of cystic lesions located in the sellar-suprasellar region is a significant problem in clinical practice because of the similarities in their clinical, radiological, and even histopathological picture. Arriving at the right diagnosis is vital for taking appropriate therapeutic decisions. The most frequent clinical manifestation of lesions located in the sellar-suprasellar region is headache. It often co-exists with symptoms of anterior pituitary gland insufficiency or hyperprolactinaemia caused by compression of the pituitary stalk. Diabetes insipidus, obe-sity, mental disorders, and circadian rhythm disorders may be associated with lesions penetrating the suprasellar space. It is extremely important to rule out the possible coexistence of pituitary microadenoma and Rathke's cleft cyst, which became possible with the use of ¹¹C-methionine positron emission tomography/computed tomography (C-MET PET/CT). Reports from literature indicate that pituitary microadenoma may coexist with Rathke's cleft cyst in 10% of patients. Cystic lesions of the sellar-suprasellar region should also be differentiated from a cystic pituitary adenoma or abscess. The first-choice therapy in symptomatic cystic lesions of the sellar-suprasellar region is neurosurgery, which usually relieves headache and improves vision impairment, while less frequently restores normal pituitary function. In suprasellar lesions, neurosurgery may trig-ger or aggravate pre-existing symptoms of damage to the hypothalamus. Patients undergoing neurosurgery for cystic lesions located in the sellar-suprasellar region should be monitored for a few years due to their high recurrence rate, potential malignant transformation of these lesions, and possible adenoma development through metaplasia. The advent of targeted therapy of the BRAF/MEK pathway is associated with new therapeutic opportunities for patients with craniopharyngiomas.

The rights of a child stem from the dignity and uniqueness of a child as an individual and are entitled to every young human being. For the first time children's rights were included in the Geneva Declaration in 1924, and their full collection was enshrined in the Convention on the Rights of the Child prepared by the United Nations in 1989. A child has the right to live without violence. In addition to physical trauma, the effects of sexual abuse of a child disrupt normal psychosexual development. Bullying of children is also punished. The law allows gentle discipline only by parents. Mental bullying, so-called systematic harassment of the child, humiliation, ridicule or insult. Sexual violence is a particular issue here. Sexual violence is defined by WHO as an abuse of children for sexual pleasure by adults or elder peers. The article discusses some issues of medical opinion in the case of sexual violence against a child. This is especially difficult for a disabled child. The knowledge of an experienced clinician, yet without the knowledge about rules of jurisprudence and with shortcomings of basic legal knowledge, is not always enough for competent opinion-making.

Introduction: The most common clinical and neurological signs and symptoms of pituitary macroadenomas include headache, vision impairment and cranial nerve palsy. Case report: The patient presented in this article was admitted to the Intensive Care Unit at regional hospital; at admission, the patient was unconscious, he had convulsions and spasms, and a 3­‍-day history of headache and body temperature up to 41.5°C. The patient with suspected neuroinfection was transferred to the Department of Infectious Diseases of the Pomeranian Medical University in Szczecin (PMU), where cerebrospinal meningitis of bacterial etiology was established based on cerebrospinal fluid investigations and the presence of pituitary abscess was suggested based on magnetic resonance imaging (MRI). Magnetic resonance imaging findings included an extensive pathological lesion with the diameter of 27 × 28 × 38 mm located in the sellar­‍-suprasellar region, with intensive peripheral contrast enhancement. The lesion protrudes into the sphenoid sinus through the lowered bottom of sella turcica and the fluid content has also been visualized in the sphenoid sinus. After 10­‍-day antibiotic therapy, the patient was transferred to neurosurgery ward for surgical treatment. The pathological lesion was partially evacuated during right frontotemporal craniotomy. The patient’s general condition after the surgery was moderately severe; the patient was conscious, able to follow simple commands, presenting hemiparesis of the left side of the body, particularly affecting left lower limb and with speech disturbances. The signs of hypopituitarism affecting all hormonal axes were also observed and the patient was transferred to the Department of Endocrinology of the PMU for further treatment. Follow­‍-up MRI scan continued to show the presence of pathological mass in the sellar­‍-suprasellar region, which penetrated into the sphenoid sinus through damaged sellar bottom. After correction of reduced hormone levels and several weeks of antibiotic therapy, the patient was transferred to the Department of Neurosurgery of the PMU for further surgical treatment. Transsphenoidal resection of the sellar­‍-suprasellar tumor and sphenoid sinus reconstruction were performed. Histopathology report confirmed the diagnosis of pituitary adenoma. The patient in relatively good condition, with partial hemiparesis on the left side of the body, able to stand with support, not able to walk, with speech disturbances and able to follow commands was transferred to the rehabilitation center. One year later, follow­‍-up MRI scan showed deepened sella turcica, filled with a mass corresponding to postoperative material. No evidence of disease progression has been found. Conclusion: Neuroinfection may be the first manifestation of pituitary macroadenoma.

Functional hypothalamic amenorrhoea (FHA) is associated with functional inhibition of the hypothalamic-pituitary-ovarian axis. Causes of FHA can be classified into the three groups: 1) stress-related factors, 2) consequences of weight loss and/or underweight, and 3) consequences of physical exercise or practicing sports. Diagnosis of FHA should be based on a history of menstrual disorders. During physical examination, patients with FHA present with secondary and tertiary sex characteristics specific for the pubertal stage preceding development of the condition and with the signs of hypoestrogenism. Laboratory results determine further management of patients with amenorrhea, and thus their correct interpretation is vital for making appropriate therapeutic decisions. Treatment of chronic anovulation, menstrual disorders, and secondary amenorrhea resulting from hypothalamic disorders should be aimed at the elimination of the primary cause, i.e. a decrease in psycho-emotional strain, avoidance of chronic stressors, reduction of physical exercise level, or optimisation of BMI in patients who lose weight. If menses do not resume after a period of six months or primary causative treatment is not possible, neutralisation of hypoestrogenism consequences, especially unfavourable effects on bone metabolism, become the main issue. Previous studies have shown that oestroprogestagen therapy is useful in both the treatment of menstrual disorders and normalisation of bone mineral density. Hormonal preparations should be introduced into therapeutic protocol on an individualised basis. (Endokrynol Pol 2015; 66 (3): 252–268)

Background. Oral contraceptives (OCs) modify the hemostatic system in the direction of hypercoagulability, which leads to an increased risk of venous thromboembolism. The risk of venous thrombosis with oral contraceptives (OCs) use is estimated at 2-3x, or 4-7x normal with third-generation OCs. Aim. The effect of OCs, taken for >3 months, on hemostatic disorders in young women was examined. Objectives were to examine whether OCs, or OCs together with smoking, induced a hypercoagulable state. Material and methods: Healthy women (n=73), aged 19-25 years, formed two groups: OC group (n=37): OCs used for >3 previous months; Control group (n=36): never used OCs. Most important assessed parameters were: prothrombin time (PT), activated partial thromboplastin time (APTT), global activity of protein C (PiCi) and resistance to activated protein C (APCR). Results. OC group had lower PiCi/APTT mean values relative to controls (PiCi: 79.9 ± 6 vs 84.2±4%, p=0.0006; APTT: 29.7±2.7 vs 32.1±2.6 s, p=0.0003), suggesting hemostatic disturbance in anticoagulant protein C pathway (PiCi) and plasma coagulation (APTT). Smoking women taking OCs had lower APRC (2.70±0.46 vs 3.02±0.20, p= 0.037). Moreover, lower APCR had high correlation with shorter APTT (r=0.65, p=0.081) or PT (r=0.77, p=0.025), indicating changes in the protein C anticoagulant pathway under influence of smoking and OCs. Conclusions. OCs possibly induce hemostatic disorders with hypercoagulation condition. This on the one hand weakness manifested protein C anticoagulant activity, expressed most strongly among women smokers, on the other hand the activation of plasma coagulation. Hypercoagulability activates anticoagulant compensatory mechanisms including increases in fibrinolytic and antithrombotic activities. Absolute indication for nicotine abstinence and healthy body mass are recommended for women using OCs.

Introduction: Pituitary gland adenomas producing prolactin are one of the commonest hormonally active tumours. Pharmacological treatment using of dopamine receptors agonists is the therapy of choice in a case of prolactinoma. Bromocriptine, which causes numerous side‑effects is the most commonly used drug. Recently, good results of therapy have been achieved with cabergoline – a selective dopamine receptor agonist with prolonged time of action. The aim of the study was to evaluate therapy with cabergoline of men with macroprolactinoma based on clinical, hormonal and radiological examinations. Material and methods: Ten men aged 18–65 (mean 41.9 ±15.01 years) with the presence of a pathological mass in the pituitary gland sized between 16.7 and 40.5 mm (mean 29.8 ±9.38 mm) and an elevated prolactin (PRL) level of between 37.3 and 4700 ng/mL (mean 1608.2 ±1771.6 ng/mL) were included in the study. The PRL and other trophic hormones levels were evaluated after 1, 3, 6 and 12 months, and tumour size was evaluated by magnetic resonance imaging examination after 12 months of therapy with cabergoline. Results: Therapy with cabergoline led to remission of headaches, visual acuity correction, and a significant improvement in libido and erection in all patients. In 90% of patients, PRL normalisation was achieved, just the initial months of therapy. The mean PRL serum concentrations were before, and after 1, 3, 6 and 12 months of therapy respectively, 1608.2 ±1771.6 ng/mL and 263.4 ±223.4, 136.1 ±244.7, 91.31 ±105.5 and 27.5 ±57.7 ng/mL. A significant tumour size reduction was observed: from 29.8 ±9.4 mm to 23.2 ±9.4 mm, a mean reduction of about 6 mm, or 25.1% (from 4–48.5%). No significant correlation between the mean tumour size and PRL level was observed before or during the treatment. A decreased testosterone level before the therapy was proven, and its gradual increase during the treatment was observed, but after 12 months no normal mean testosterone concentration was achieved. Conclusions: 1. The administration of cabergoline to patients with macroprolactinoma is effective in reaching PRL level normalisation as well as in tumour size reduction. 2. Therapy with cabergoline significantly decreases the clinical symptoms of hyperprolactinemia and neurological and ophtalmological changes associated with the presence of a pathological lesion in the pituitary gland. 3. Tumour size is not a predictive factor for the effectiveness of therapy with cabergoline.

Introduction: Childhood obesity has been associated with the development of insulin resistance, potentially leading to several metabolic disorders. Osteocalcin has been reported to contribute to the regulation of glucose tolerance and insulin sensitivity. The purpose of this study was to examine the relationship between serum osteocalcin and metabolic risk factors in obese children and adolescents. Material and methods: Age, gender, pubertal stage, adiposity markers (standard deviation score of body mass index: BMI-SDS, percentage of body fat, waist circumference), blood pressure, serum osteocalcin (OC), fasting plasma glucose and insulin, glycated haemoglobin level (HbA1c), insulin resistance estimated by homeostasis model assessment (HOMA-IR), lipid profile, C-reactive protein (CRP), fibrinogen (FB), white blood cell count (WBC) and 25-hydroxyvitamin D (25-OH-D) were evaluated in 142 obese children and adolescents. Stepwise multiple regression analysis was used to determine the relationship between serum osteocalcin and metabolic risk parameters. Results: Mean serum osteocalcin level was 72.0 ± 20.5 μg/L (range: 16.8–181.5 µg/L). After adjustment for multiple potential confounders, serum osteocalcin concentration was inversely associated with adiposity markers as well as HOMA-IR, HbA1c, triglycerides, CRP, FB and positively with 25-OH-D and HDL-cholesterol. In stepwise multiple linear regression analysis adjusted for age, gender and pubertal stage, osteocalcin was significantly negatively related to HOMA-IR, triglycerides and waist circumference. Conclusions: Serum osteocalcin concentration is associated with blood markers of dysmetabolic phenotype and measures of adiposity, suggesting that osteocalcin is important not only for bones but also for glucose and fat metabolism as early as during childhood.

Introduction The aim of this study was the long-term prospective evaluation of the effects of estroprogestagen (EP) therapy on the bone mineral density (BMD) of girls with functional hypothalamic amenorrhea (FHA) carrying various PvuII and XbaI polymorphisms of ER-α. Material and methods Prospective observation included 84 FHA girls and 50 controls. The FHA patients were subjected to 4-year sequential therapy with 17β estradiol (2 mg from the 2nd to 25th day of the menstrual cycle) and dydrogesterone (10 mg from the 16th to the 25th day). Hormonal parameters, serum concentration of the bone fraction of alkaline phosphatase (BALP), urine concentration of cross-linked n-telopeptide of type I collagen (Ntx) and BMD were determined before and after the treatment. Results Six-month treatment resulted in a marked increase in estradiol (p = 0.001), testosterone and prolactin levels (p = 0.01 both) and a significant decrease in BALP and Ntx (p = 0.001 both). Patients with the PP polymorphism had significantly lower baseline BMD compared to carriers of other polymorphic variants of PvuII (p = 0.003). A significant increase in BMD was observed throughout the entire therapy period, with no significant differences in the yearly dynamics of BMD changes observed amongst various polymorphic variants and haplotypes of ER-α. Conclusions The EP therapy is effective in the treatment of BMD disorders associated with FHA, and treatment results do not depend on PvuII and XbaI polymorphisms of ER-α.

Reduced bone mineral density (BMD) is present in many women with Turner syndrome (TS), and hypo-estrogenism is known to play a vital role in bone mineralization disturbances. It has been suggested that genetic factors play an important role in the regulation of BMD. The aim of this study was to analyze the association between Pvu II and XbaI ER-α polymorphisms and BMD in TS patients subjected to estroprogestagen (EP) treatment. Thirty-two TS patients aged 17–38 (mean age 22.7 ± 8.2) along with 82 healthy controls were the subjects for this study. Baseline values of hormonal parameters, BMD and bone density markers were measured in the subjects. Subsequently, TS patients underwent 4 years of EP therapy. The results of laboratory parameters and BMD were analyzed in regard to PvuII and XbaI polymorphic variants of the ER-α gene. The increase in BMD of TS subjects was the highest in the 1st (7.5%, p = 0.013) and 2nd (6.6%, p = 0.008) years of treatment. Four years of EP therapy was reflected by a significant increase in BMD z-scores in patients with xx and Xx genotypes of the XbaI gene and in those with with the pp and Pp genotypes of PvuII. In patients with haplotypes other than XXPP, BMD z-scores were significantly higher compared to their baseline after 2 (p = 0.002), 3 (p

If menses do not resume after a period of six months or primary causative treatment is not possible, neutralisation of hypoestrogenism consequences, especially unfavourable effects on bone metabolism, become the main issue. Previous studies have shown that oestroprogestagen therapy is useful in both the treatment of menstrual disorders and normalisation of bone mineral density. Hormonal preparations should be introduced into therapeutic protocol on an individualised basis.
