Abstract
BACKGROUND Fibroblast growth factor 21 (FGF21) is a hepatokine, myokine and adipokine of a potent influence to energy homeostasis. Data according its serum concentrations in AN are contradictory. OBJECTIVES Analysis of serum FGF21 in girls with acute anorexia nervosa and comparison the results with normal weight and obese female adolescents considering their nutritional status, carbohydrate and lipid metabolism. METHODS Serum FGF21 concentrations were evaluated using commercially available ELISA kit in 32 Polish girls with restrictive AN (AN), 29 girls with obesity (O) and 21 healthy controls (C). Anthropometric measurements (weight, height, BMI) and laboratory assays (serum fasting glucose, insulin, HOMA-IR, total cholesterol, HDL, LDL, triglycerides, C-reactive protein) were performed. RESULTS Mean serum FGF-21 in the AN group was significantly lower, whereas in the O group it was significantly higher than in healthy controls. In all examined girls significant positive correlations between FGF21 and BMI were noted. We also observed significant positive relationships between serum FGF21 levels and fasting glucose, triglycerides, CRP, insulin and HOMA-IR. In all examined girls serum concentrations of this hormone correlated negatively with age and HDL-cholesterol levels. CONCLUSIONS 1) Serum FGF21 concentrations are decreased in AN and elevated in obesity. They are independently and positively related to BMI and insulin resistance; 2) Decreased serum FGF21 in AN may support the maintenance of normal blood glucose through adjustment the insulin levels and insulin sensitivity; 3) Elevated FGF21 levels in obesity may be considered adaptive mechanism preventing insulin resistance and its metabolic consequences.

Abstract
BACKGROUND A possible role of adipokines in the regulation of body weight in patients with anorexia nervosa (AN) has been proposed. Polymorphisms in genes encoding adiponectin and resistin in AN have not been widely assessed, yet. OBJECTIVES 1) Assessment the frequency of ADIPOQ c.45T>G, ADIPOQ c.276G>T polymorphisms in adiponectin and RETN c.62G>A, RETN c.-180C>G in resistin genes in AN patients and control group (C) 2) Analysis of correlation between these polymorphisms and serum ADP or RETN. METHODS We examined 67 AN girls and 38 C aged 11-18. Analyses of polymorphisms in ADIPOQ and RETN genes were performed using RFLP method and adiponectin and resistin serum levels - with commercially available ELISA kits. RESULTS In AN subjects, TT genotype in ADIPOQ c.276 polymorphism as well as GG genotype of RETN c.-180 were significantly more frequent than in CG. In ADIPOQ c.45 polymorphic site, TT alleles were the most frequent in both examined groups. In RETN c.62 GA and GG alleles distribution did not differ between the groups and the most frequently observed genotype was GG. The mean serum adiponectin level in AN was significantly higher and resistin - lower than in controls. There were no statistically significant relationships between serum adiponectin and resistin levels and allele frequency in polymorphisms ADIPOQ c.276 as well as RETN c.-180 in the examined groups. CONCLUSION Differences in genotype frequencies of ADIPOQ c.276 and RETN c.-180 suggest a need for studies on a larger cohort of patients with AN.

Abstract
OBJECTIVES Stimulation of some noradrenergic system receptors demonstrates a synergistic anti-nociceptive effect with the opioid system at the level of peripheral tissues, spinal cord, and supraspinal structures. Furthermore, opioids stimulate the noradrenergic descending pathways originating from the substantia nigra by presynaptic inhibition of the GABA neuron ends. It is thus important to determine whether a disruption to the adrenergic transmission obtained via DPS-4 administration to neonatal rats impacts the perception of noxious stimuli mediated by 5-HT3-serotonin receptors at the level of spinal cords or higher tiers of the central nervous system. DESIGN & SETTING The studies were conducted with neonatal and adult rats, males of the Wistar strain in which a central noradrenergic system lesion was induced with DSP-4 on days 1 and 3 of life. Next, the evaluation of the analgesic effect of morphine was performed on 8- to 10-week-old animals using the following models of acute nociceptive pain: the hot plate test and the tail immersion test as models of acute nociceptive pain induced by a thermal stimulus, and the paw withdrawal test as a model of nociceptive pain caused by a mechanical stimulus. RESULTS Morphine was found to produce a longer-lasting analgesic effect in the tail immersion test in the control group than in rats. Similarly, in the paw withdrawal test, this substance generated a strong analgesic effect (with over 200% of analgesia) in the control group, whereas its action in the rats with DSP-4 lesions was statistically significant. Morphine induced analgesia at about 13-14% in the control rats when examined with the hot plate test. CONCLUSIONS The disruption to the central noradrenergic system in an early stage of development resulted in a reduction of the analgesic effect of morphine in the models of acute pain in which the mechanisms of supraspinal perception are involved.

Abstract
BACKGROUND Soluble α-klotho may influence energy homeostasis. It also plays a role in calcium-phosphate and vitamin D3 metabolism regulation. Two so far published studies have demonstrated that serum α-klotho levels in patients with AN are decreased, but their relationships with BMI and metabolic disturbances in these patients remain unclear. OBJECTIVES The aim of the study was to assess the association between serum soluble α-klotho levels and glucose, calcium-phosphorus and vitamin D3 metabolism in girls with acute AN. METHODS Serum soluble α-klotho concentrations were evaluated using commercially available ELISA kit in 31 Polish girls with restrictive AN and 29 healthy controls (C). Moreover, anthropometric measurements (weight, height, BMI) and laboratory assays (serum fasting glucose, insulin, HOMA-IR, total calcium, phosphorus as well as 25-hydroxy vitamin D3 and calcitriol) were performed. RESULTS The mean serum α-klotho concentrations in the AN group were significantly lower than in the C group even after adjustment for BMI. Significant correlations between serum α-klotho and body mass (r=0.54; p=0.009), BMI (r=0.48; p=0.02), serum calcitriol (r=0.48; p=0.03), insulin (r=0.49; p=0.008) and HOMA-IR (r=0.54; p=0.006) were observed in the AN, but not in healthy controls. CONCLUSIONS Serum α-klotho concentrations in female adolescents with AN are decreased in comparison with normal weight girls and strongly associated with their nutritional status, insulin sensitivity and active vitamin D3 levels.

Abstract
BACKGROUND Transition is a term used to describe the period of adolescence after which the final adult height during growth hormone (GH) treatment is achieved. According to re-evaluation results in insulin tolerance test (ITT) patients with severe and partial growth hormone deficiency (GHD) may be distinguished. OBJECTIVES The aim of the study was to assess QoL in patients with different degrees of GHD in transition phase. METHODS QoL was evaluated in 76 subjects aged 16-25 years with severe (SGHD, n=26), partial GHD (PGHD, n=22) and normal GH secretion (NGH, n=28) using SF-36 v.2™ Health Survey and the Quality of Life Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA) questionnaires. RESULTS Physical Component Score (PCS), Physical Functioning (PF) and General Health (GH) results were significantly lower in patients with SGHD than in NGH group. SF-36 v.2™ Health Survey scores in PGHD were similar as in NGH patients. There were no statistically significant differences in QoL-AGHDA scores between the examined groups. We found positive correlations between peak GH in ITT and PF (r=0.29; p=0.02) or Role Emotional (r=0.37; p=0.002) scores. CONCLUSIONS We demonstrated that the QoL in adolescents and young adults with severe GHD in transition period is disturbed mainly in terms of physical health and emotions. These changes were detected only by generic SF-36, but not by disease-specific QoL-AGHDA questionnaire. Therefore AGHDA-QoL assessment may not be applicable in GHD patients in transition period. QoL in the patients with partial GHD is unchanged in comparison to growth hormone sufficient subjects.

Abstract
OBJECTIVES There are limited data on the role of adipokines in atopic asthma. DESIGN AND SETTING To determine serum levels of resistin in asthmatic children in relation to body weight, asthma severity and gender, serum resistin (RES) levels were measured using ELISA in 89 asthmatic children (61 boys and 28 girls, aged 7.0-17.0 years) and in 33 healthy children. Among examined asthmatics 59 (19 girls and 40 boys) had normal weight (ANW) and 30 (9 girls and 21 boys) were obese (AO). RESULTS The mean serum levels of resistin were significantly (p<0.01) higher in all non-obese asthmatic children (4.11±0.1 ng/mL) than in healthy children (3.83±0.1 ng/mL). After stratifying by gender only ANW boys and AO boys had significantly higher RES levels than boys from control group. Both AO (4.4±0.2 ng/mL) and ANW girls (4.38±0.2 ng/mL) as well as girls from control (4.09±0.1) group showed significantly higher mean RES serum concentrations than boys from corresponding groups (3.99±0.1 ng/ml, 3.83±0.17 ng/ml and 3.44±0.06 ng/ml, respectively). No relationship between examined adipokine levels and asthma severity, spirometric parameters, degree of allergic sensitization, BMI, BMI-SDS was stated. CONCLUSION Increased serum RES in children with atopic asthma suggest that this adipokine may be implicated in its pathogenesis.

Abstract
OBJECTIVES Excessive hyperandrogenism, though proper hydrocortisone supplementation is a frequent clinical problem in girls with congenital adrenal hyperplasia (CAH). This may result from autonomic regulation of androgen production established in prenatal life. It has been suggested that the length of the second finger relative to the length of the fourth finger (2D;4D ratio) is negatively related to prenatal testosterone concentration. DESIGN AND SETTING The retrospective study aimed to establish the relationship between the level of androgenization in utero determined using 2D:4D ratio and serum androgen concentrations in treated girls with CAH (21-OH deficiency) has been performed on 19 girls with CAH (21-OH deficiency) at the age of 3.7-19 years (mean 13.8 ± 4.07 years). All subjects were adequately treated with hydrocortisone (10-19 mg/m2; mean 13.81 ± 4.07 mg/m2). Anthropometric measurements of digits length were performed in all girls on X-rays obtained for bone age estimation. Apart from it, serum androgens concentrations (testosterone, androstenedione, s-DHEA) and 17-OH-progesterone (17-OHP) were assayed. RESULTS Mean androgens serum concentrations in examined group were: testosterone 150.21 ± 155.44 ng/ml; androstenedione 4.15 ± 5.32 ng/ml, s-DHEA 70.39 ± 85.52 µg/dl. Mean 2D:4D ratio was 0.96 ± 0.04. Analysis of correlation showed positive linear correlations between testosterone, s-DHEA and 2D:4D ratio (r=0.53, p=0.023 and r=0.53; p=0.019, respectively). CONCLUSIONS 2D:4D ratio parameter may be a simple test in indentification of female CAH patients prone to excessive androgen secretion despite proper treatment. The autonomization of adrenal androgens production in foetal life may cause its elevated levels in female patients with CAH although treated adequately.

Abstract
OBJECTIVES Thyroid, adrenal glands and gonadal hormones play a role in maintaining metabolic homeostasis of the body via the receptors located in the adipose tissue. The correlations between serum resistin (RES) and function of other hormonal axes in patients with AN have not been established, yet. Therefore, the aim of this study is: 1) assessment of concentrations of thyroid hormones (FT4, TSH), adrenal hormones (ACTH, cortisol), sex hormones (LH, FSH, estradiol, testosterone); 2) establishing their relationship with BMI and 3) analysis of correlations between examined hormones and RES serum concentrations in adolescent female patients with AN. DESIGN AND SETTING Serum RES (ELISA) and fT4, TSH, ACTH, LH, FSH, estradiol and testosterone (ECLIA) concentrations have been assayed in 195 adolescent girls: 87 with restrictive AN, 17 with not otherwise specified eating disorders (NOS), 30 with simple obesity (OB) and 61 healthy (H) subjects. RESULTS Mean serum FT4, LH and estradiol concentrations were significantly lower (p=0.015; p<0.0001; p<0.0001, respectively) in AN than in OB group, and cortisol increased (p<0.001) compared to OB and H subjects. In all examined subjects BMI correlated positively (p<0.0001) with LH (r=0.61) and estradiol (r=0.30), and negatively with cortisol (r=-0.35; p=0.008). Also the significant positive relationship between serum RES and FT4 (r=0.34), LH (r=0.57) as well as estradiol (r=0.28) was observed, whereas serum cortisol correlated negatively with RES (r=-0.40). CONCLUSION Changes in resistin serum concentrations in eating disorders may be involved in the altered regulation of hypothalamic-pituitary-adrenal, thyroid and gonadal axes.

Abstract
OBJECTIVES There are only few studies available on blood resistin (RES) levels in patients with anorexia nervosa (AN), which revealed scarce results, however it has been demonstrated that RES mRNA expression in adipose tissue of these patients is increased. The aim of this study is: 1) the evaluation of serum resistin levels in girls with AN and determination a threshold value differentiating these patients from healthy subjects; 2) analysis of the relationship between serum resistin levels and BMI in examined subjects. DESIGN AND SETTING Serum RES concentration has been assayed using ELISA kit in 195 adolescent girls: 87 with restrictive AN (mean BMI-SDS: -2.65 ± 0.2), 17 with not otherwise specified eating disorders (NOS) (mean BMI-SDS: -1.4 ± 0.68), 30 with simple obesity (OB) (mean BMI-SDS: 6.91 ± 1.23) and 61 healthy (mean BMI-SDS: -0.18 ± 0.54). RESULTS Mean serum RES concentration in AN (2.8 ± 0.6 ng/ml) and NOS (3.1 ± 0.9 ng/ml) were significantly lower (p<0.0001) than in OB and H groups (4.8 ± 0.5 and 4.1 ± 0.4 ng/ml respectively). After corrected for BMI, RES values in AN were similar as in H subjects, but significantly higher (p<0.005) in comparison to OB group. ROC curve analysis revealed that 3.87 ng/ml is the threshold value of RES serum concentration differentiating AN from H girls (specificity 100%, sensitivity 80%). No significant correlations between BMI and serum resistin concentration are found in AN group, although a significant positive correlation has been established for all examined subjects. CONCLUSION Additional adaptive mechanisms may be involved in regulation of RES levels in adolescent girls with AN.

Abstract
INTRODUCTION Ambiguous genitalia always present diagnostic and therapeutic problem. Long-term results of feminizing operations are unsatisfactory in some cases and reports from follow-up after feminizing genitoplasty are rare in the literature. Systematic studies are needed to evaluate ultimate function of all girls undergoing feminizing surgery. In our opinion, the lack of worldwide-accepted scale for the assessment of long-term effects of feminizing genitoplasty, enabling the possibility of comparing outcomes between institutions and countries, may contribute to this deficit of reliable data. AIM The aim of the study was the evaluation of the outcomes of surgical management of masculinization using a novel scale developed by the authors. MATERIAL AND METHODS We examined 43 patients aged 3-24 years (mean age 15,4 years) operated due to ambiguous genitalia. Most of the patients were females with congenital adrenal hyperplasia (CAH) diagnosed in 38 of subjects (88.4%).The patients were operated at the age from 10 months - 15 years (mean age 4,5 years). Five patients had to be reoperated. The effects of surgical management in ambiguous genitalia were assessed using our own scale. We evaluated five anatomical and cosmetic parameters (general appearance, size of pudendal labia, symmetry of pudendal labia symmetry, size and position of clitoris, size of introitus and position of urethra opening), each of them was scored 0-2 points. RESULTS In 36 of examined patients the result of the surgery was considered good, in 4 patients - satisfactory and in 3 - poor. The most common complication of feminizing genitoplasty in our patients was stenosed vagina (in 10 patients, 23.8%). Location of urinary coil in anterior wall of vagina was found in 6 patients (13.9%) and in 1 patient it was invisible (2.3%). Post-operational clitoral enlargement was found in 3 cases (6.9%). CONCLUSION Taking into consideration controversial data about the results of feminizing genitoplasty, a standarized, well-defined and commonly accepted scale enabling comparison between methods and institutions is necessary. In our opinion scoring scale makes the evaluation more precise and the results are more comparable.

Abstract
Pilomatricoma is usually a solitary subcutaneous nodule. Recurrence of the nodule after surgical excision is very rare. Pilomatricoma occurrence in patients with growth hormone (GH) deficiency has not been reported, yet. We report a 14-year-old boy with pilomatricoma and panhypopituitarism. After GH therapy had been started, we observed two relapses of previously completely excised pilomatricoma in the same location and a new pilomatricoma formation on the chin.
