Item A relationship of sex hormone levels and erectile dysfunction: Which tests should be done routinely?(2007) Müezzinoǧlu T.; Gümüş B.; Temeltaş G.; An Z.; Büyüksu C.Purpse: In this study, the relationship between sex hormone levels and erectile dysfunction (ED), as well as the necessity of routinely measuring sex hormone levels were evaluated. Materials and Methods: This study included one hundred patients admitted to a urology clinic for sexual dysfunction. To determine the hormone levels, following the history (included IIEF-5 score) and physical examination, triple blood samples were collected at intervals of 15 minutes between 08:00 and 10:00 am. Total and free testosterone, prolactin, follicle stimulating hormone and leteinizing hormone levels were studied. Results: Mean ago was 43 (23 - 80) years. IIEF-5 score was less than 21 [9.8 - 4.3 (3 - 19)] in all study groups. There was a statistically significant correlation between tT and FSH, as well as between LH and FSH in Pearson (r = - 0.513, p < 0.001, respectively) and also in Spearman tests (r = - 0.224, p = 0.042 and r = - 0.459, p < 0.001, respectively). However, there was no correlation between age and serum hormone levels (p > 0.05). Of the 100 patients, 18 (18%) had low tT, 77 (77%) had normal and 5 (5%) had high tT levels. No statistically significant correlation was found between decreased libido and tT levels (p > 0.05). Twelve (66.6%) of the 18 patients with low tT had normal libido. Conclusion: Analyzing the medical history in detail and performing a thorough physical examination can reduce the need for excessive studies and consultations, and enables patients to save time and costs.Item The prevalence of hyperprolactinaemia in overt and subclinical hypothyroidism(2010) Hekimsoy Z.; Kafesçiler S.; Güçlü F.; Özmen B.The aims of this study were to: 1) determine the prevalence of hyperprolactinaemia in patients with newly diagnosed subclinical and overt hypothyroidism, and 2) investigate the change in PRL levels with treatment. In this observational study, patients with a new diagnosis of hypothyroidism in our endocrinology clinic were approached for participation, as were healthy controls. Patients with medical reasons for having elevated PRL levels, lactating and pregnant women were excluded from the study. No patient had kidney or liver disease. After examination to determine if clinical causes of PRL elevation were present, serum levels of thyrotropin (TSH), free thyroxine, free triiodothyronine and PRL were measured and correlation of PRL levels with the severity of hypothyroidism (overt or subclinical) was performed. Fifty-three patients (45 women, 8 men, mean age 45.3±12.2 years) had overt hypothyroidism. One hundred forty-seven patients (131 women, 16 men, mean age 42.9±12.6 years) had subclinical hypothyroidism. One hundred healthy persons (85 women, 15 men, mean age 43.9±11.4 years) participated as controls. The same blood tests were repeated in patients after normalization of TSH levels with L-thyroxine treatment. PRL elevation was found in 36% of patients with overt hypothyroidism, and in 22% of patients with subclinical hypothyroidism. PRL levels decreased to normal in all patients after thyroid functions normalized with L-thyroxine treatment. In the hypothyroid patients (overt and subclinical) a positive correlation was found between TSH and PRL levels (r=0.208, p=0.003). PRL regulation is altered in overt and subclinical hypothyroidism, and PRL levels normalize with appropriate L-thyroxine treatment.© The Japan Endocrine Society.Item Parental attitude in women with hyperprolactinemia: A controlled cross-sectional study; [Ailesel tutumun hiperprolaktinemi üzerine etkisi: Kesitsel kontrollü bir çalışma](Turkish Biochemistry Society, 2011) Ulman C.; Aydemir O.; Taneli F.; Aksun S.; Öztin A.; Cennet S.; Laçin S.Objective: Prolactin hormone affects the brain, attitude and mood. Secretion of prolactin may be stimulated by environmental factors. The aim of this study was to demonstrate any possible effect of poor child-parent relationship on hyperprolactinemia. We hypothesize that women with hyperprolactinemia may have been subjected to poor child-parent relationship and neglect. Method: The present study was designed in a maternity hospital and included women with gynecologic complaints referred from the gynaecology outpatient clinic for serum prolactin assessments. An 85-item, self-rated EMBU Scale questionnaire (a scale for perceived parental attitude) was applied. Fifty women were enrolled over a period of 5 months. Results: Women with hyperprolactinemia (prolactin levels above 26 ng/ml) constituted the patient group (Group 1) (n=34) and those with normal serum prolactin levels (below 26 ng/ ml) served as the controls (Group 2) (n=16). The mean±SD levels of prolactin for group 1 and 2 were 57.25±38.7 ng/ml and 18.81±4.4 ng/ml, respectively. Group 1 patients believe that their parents did not show enough emotional warmth and had rejective behavior. Emotional warmth parameters of patients' mothers and fathers were significantly lower (p=0.002 and p=0.01, respectively) than those of the control group. We also found that the patients believed that their mothers and fathers both had rejective behaviors (p=0.008 and p= 0.009, respectively). Conclusion: Prolactin secretion is regulated by the dopaminergic system and since dopamine is responsible of pleasure and satisfaction sensations, the negative affection of both mothers and fathers in childhood may play a role in the etiology of chronic low-grade hyperprolactinemia in women. © TurkJBiochem.com.Item Sexual function and hormone profile in young adult men with idiopathic gynecomastia: Comparison with healthy controls(IOS Press, 2016) Sir E.; Üçer O.; Aksoy A.; Güngör M.; Ceylan Y.Objectives: To compare sexual function and hormone profile in male patients with gynecomastia with matched controls. MATERIALS-METHODS: Forty-seven male subjects with gynecomastia and thirty healthy controls were enrolled in this study. Serum free T3, free T4, TSH, FSH, prolactin, estradiol, total testosterone, free testosterone, DHEA-SO4, LH and total PSA were measured in the patients and controls. Sexual function of the patients and controls were evaluated using International Index of Erectile Function (IIEF). The hormone values and IIEF scores of the patients were statistically compared with the controls'. RESULTS: The mean of age, body mass index, right and left testicular volume in the patient and control group were similar. The mean FSH and free T3 values of the patients were significantly lower than the controls (p = 0:007 and p = 0:03, respectively). The mean of the other hormone values in the both groups were found to be statistically similar (p > 0:05). The mean ±SD of total IIEF scores in the patient and control group were 60:14 ± 8:78 and 65:24 ± 5:52, respectively (p = 0:007). Although the mean IIEF-erectile function, orgasmic function and intercourse satisfaction scores in the patient group were significantly lower than the control group (p < 0:001, p = 0:004 and p = 0:001, respectively), the mean IIEF-desire score of the patients was significantly higher than the controls (p = 0:002). CONCLUSION: We found that the hormone profiles (except FSH and free T3) of the patients with gynecomastia were similar with the controls. However, gynecomastia adversely affected male sexual function. © 2016-IOS Press and the authors.

The purpose of this study was to investigate the potential side-effects of metoclopramide applied in the lactation period in the central nervous system of offspring rats. Eighteen female albino Wistar rats that had just given birth were divided into three groups together with their pups, healthy controls, low-dose metoclopramide (10 mg/kg, twice per day i.p.) and a high-dose metoclopramide group (45 mg/kg, twice per day i.p.). Brain tissues from six pups from each mother were harvested at the end of the 21st day. Immunohistochemical and ELISA techniques were performed using dopamine D2 receptor (DRD2), brain derived neurotrophic factor (BDNF) and neural growth factor (NGF), markers of extrapyramidal reaction in the brain, as signal molecules. Based on biochemical levels and immunohistochemical results, DRD2 expression decreased only in the external pyramidal layer neurons in the high-dose offspring group. Strong BDNF reaction was determined in pyramidal neurons in all layers in the control offspring group, and decreased reaction was observed in the high- and low-dose groups. No significant difference was observed in NGF expression between the three groups. Since high-dose metoclopramide caused a decrease in DRD2 expression in the external pyramidal layer in the prefrontal cortex, and since both high and low doses reduced BDNF expression, care needs to be taken with the use of metoclopramide in the lactation period due to the possibility of extrapyramidal reactions in offsprings. © 2020 Elsevier B.V.Item CATAMENIAL DIABETIC KETOACIDOSIS(Acta Endocrinologica Foundation, 2022) Hekimsoy Z.; Eniseler E.B.; Erdem N.; Ozdemir N.Diabetic ketoacidosis (DKA) is a common medical emergency situation. In rare cases, glycemic changes associated with the menstrual cycle may create a predisposing factor for DKA. In the absence of facilitating factors that may cause DKA, catamenial DKA should be considered. In the patients with catamenial DKA, increasing the insulin dose 1-2 days before menstruation may prevent the development of hyperglycemia or DKA associated with menstrual cycle. In this study, we present a 21-year-old female with type 1 diabetes mellitus (DM) that recurrently applied to our hospital due to DKA a few days prior to menstrual bleeding. © 2022, Acta Endocrinologica Foundation.
