Abstract
OBJECTIVES Both polycystic ovary syndrome (PCOS) and autoimmune thyroiditis (AT) are reported to be common endocrinopathies. In recent years the number of publications assessing the coexistence of these two disease entities in adult women has been growing. There are many suggestions regarding pathophysiological mechanisms that can cause the relationship between AT and PCOS. However, there is still a lack of research among adolescent girls. The aim of the study was to analyze the occurrence of autoimmune thyroiditis in adolescent girls with PCOS. MATERIAL AND METHODS The study group included 80 girls diagnosed with PCOS (chronological age: 16.54 ± 1.00 years, BMI: 22.80 ± 3.27 kg/m2), and the control group - 64 regularly menstruating girls (chronological age: 16.71 ± 0.63 years, BMI: 24.8 ± 5.2 kg/m2). The thyroid function and morphology were assessed based on the concentration of thyroid stimulating hormone (TSH), free thyroxine (fT4), anti thyroid peroxidase (anti-TPO), anti-thyroglobulin (anti-TG) antibodies and ultrasound scan of the thyroid gland. RESULTS AT was diagnosed in 18 (22.5%) girls from the study group and nine (14.06%) from the control group (p > 0.05). Positive anti-TPO titer was observed more often in the study group [21 patients (26.25%)] than in the control group [9 girls (14.06%)] (p = 0.054). Moreover, an abnormal ultrasound scan of the thyroid gland characteristic for AT was found in 18 girls from the study group (22.50%) and 8 girls from the control group (12.50%) (p > 0.05). CONCLUSIONS The results of the analyzed studies do not confirm a significant relationship between PCOS and AT in adolescent girls. However, in the group of girls with PCOS, autoimmune process exponents were more frequent (anti-TPO), reaching the borderline level of statistical significance.

Abstract
Background Severe early-onset obesity (SEOO) in children is a common feature of monogenic obesity. Gene defects of the leptin-melanocortin pathway can be analysed biochemically and genetically. The aim of this study was to search for children with leptin deficiency or biologically inactive leptin in a cohort of children with SEOO and to study associations between leptin parameters and anthropometric data. Methods The cohort included n = 50 children with SEOO (22 boys) who were recruited at one of four study centres (Germany: Ulm; Poland: Katowice, Szczecin, Rzeszow) between October 2015 and October 2017. Weight (kg) and height (m) were measured, Tanner stage was obtained and a fasting serum blood sample was taken. Serum levels of total leptin (LEP, ng/mL), biologically active leptin (bioLEP, ng/mL) and soluble leptin receptor (sLEPR, ng/mL) were measured. The body mass index (BMI [kg/m2]), BMI z-score (World Health Organization [WHO]), quotient of bioLEP/LEP and leptin-standard deviation score (LEP-SDS) (Tanner stage, BMI and sex-adjusted) were calculated. Results We did not find any child with leptin deficiency or biologically inactive leptin in our cohort. The serum LEP and bioLEP levels were strongly correlated with age (r = 0.50, p < 0.05) and BMI (r = 0.70; p < 0.0001). Girls had higher LEP and bioLEP levels (49.7 ± 35.9 vs. 37.1 ± 25.5 ng/mL, p > 0.05) as well as lower LEP-SDS than boys (-1.77 ± 2.61 vs. -1.40 ± 2.60, p > 0.05). sLEPR levels were negatively correlated with BMI values (r = -0.44; p < 0.05), LEP (r = -0.39; p < 0.05) and bioLEP levels (r = -0.37; p < 0.05). Interestingly, there was a strong inverse relationship between LEP-SDS and BMI (r = -0.72, p < 0.001). Conclusions In this cohort with SEOO, we identified no new cases of children with leptin deficiency or bioinactive leptin. A strong negative correlation between the LEP-SDS and BMI values could be interpreted as relative leptin deficiency in children with SEOO. In case this hypothesis can be confirmed, these children would benefit from a substitution therapy with methionyl human leptin (metreleptin™).

Abstract
Background: Turner Syndrome is associated with an increased risk of autoimmune diseases, such as autoimmune thyroiditis, coeliac disease, type 1 diabetes mellitus, inflammatory bowel disease, alopecia areata, or vitiligo. The presence of isochromosome iXq and exposure to estradiol may contribute to the development of the autoimmune process. The aim of this study was to determine the prevalence of autoimmune diseases in a group of TS patients and to assess the impact of karyotype and puberty on the development of autoimmune diseases. Patients and Methods: The analysis encompassed clinical and biochemical data of 134 patients treated between 2001 and 2018. All the patients were examined for autoimmune disease symptoms and tested for the presence of antithyroperoxidase (anti-TPO) and antithyreoglobulin (anti-TG) antibodies. In 73 of the patients, anti-transglutaminase (anti-tTG) antibodies were measured. Thyroid function was assessed by measuring TSH and fT4 levels. Results: The mean follow-up was 5.7 ± 3 years. An autoimmune disease was diagnosed in 46 (34.3%) patients: 39 (29.1%) had only one disorder, whilst 7 (5.2%) presented two disorders. The most common disorder, observed in 40 (29.9%) patients, was thyroid autoimmunity. Hashimoto disease was diagnosed in 20 (14.9%) patients. Of the 73 patients tested for coeliac disease, 4 (5.5%) had anti-tTG and 2 (2.7%) presented overt coeliac disease. Vitiligo was diagnosed in 3 (2.2%) patients, type 1 diabetes mellitus or psoriasis were diagnosed in 2 (1.5%) patients, whilst alopecia areata or lichen sclerosus were diagnosed in 1 (0.7%) patient. The impact of karyotype or estradiol exposure on developing autoimmune diseases were not statistically significant. Conclusions: Our study showed a higher incidence of autoimmune diseases in TS, which is in line with the literature; however, the impact of iXq, or spontaneous/inducted puberty was not confirmed.

Abstract
AIMS To investigate whether karyotype, mid-childhood (6-10 years) follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, and ultrasound ovary visualization results can be used as indicators of spontaneous puberty in Turner syndrome (TS). METHODS The analysis was based on clinical and biochemical data from 110 TS girls aged >13 years at the end of the study (1,140 visits between 1996 and 2015). The study population was divided according to karyotype: 45,X and non-45,X. RESULTS The mean age ± standard deviation at diagnosis was 10.7 ± 4.0 years, and the follow-up duration was 5.9 ± 3.3 years. Spontaneous puberty was confirmed in 48% and menarche in 20% of the subjects, less frequently in 45,X girls. The mean age at Tanner stage B2 was 13.7 ± 2.4 years and that at menarche 14.2 ± 1.7 years, regardless of the karyotype. The median FSH level at 6-10 years was 8.16 IU/L, which was significantly lower than <6 years and >10 years. The median LH level at 6-10 years was 0.35 IU/L, which was lower than >10 years. The chance of spontaneous menarche was decreased in girls with FSH ≥6.7 IU/L between 6 and 10 years. CONCLUSIONS Although spontaneous puberty and menarche occur more frequently in non-45,X girls, the karyotype cannot be used to predict them. However, the chance of spontaneous menarche can be predicted based on gonadotropin cut-off values. There was no correlation between ultrasound ovary visualization results and spontaneous puberty.

Abstract
OBJECTIVE Estrogen replacement therapy (ERT) for Turner syndrome (TS) is a widely discussed topic; however, the optimal model of ERT for patients with delayed diagnosis and/or initiation of therapy is still unclear, mainly due to insufficient data. We present the results of a prospective observational single-center study in which the efficacy of late-onset puberty induction by one-regimen transdermal ERT in TS girls was evaluated. METHODS The analysis encompassed 49 TS girls (63.3% with 45,X) with hypergonadotropic hypogonadism in whom unified transdermal ERT protocol was used for puberty induction (first two months 12.5 μg/24 h, thereafter 25.0 μg/24 h until breakthrough bleeding). Clinical visits for examination and therapy modification took place every 3-6 months. Transabdominal pelvic ultrasound examinations were performed at least twice: at the beginning and at the end of follow-up. RESULTS The mean (SD) age at ERT induction was 15.1 (1.3) years. The duration of follow-up was 2.4 (1.1) years. Half of all the patients had at least B2 after 0.57 years, B3 after 1.1 years, B4 after 1.97 years, and menarche after 1.82 years from ERT initiation. With earlier initiation of ERT (≤14 years), B2 (p = 0.059) was achieved faster and B4 (p = 0.018) significantly slower than with the later start of ERT. Thirty-four (94.4%) patients had at least stage B3 at menarche. The karyotype, initial weight, and body mass index had no impact on puberty tempo during ERT. The uterine volume increased significantly during ERT in all the study group (p < 0.0001), and in half of the patients, the increase was at least 12.4-fold. It did not correlate with the duration of treatment (p = 0.84) or the dose of estradiol per kilogram (p = 0.78), nor did it depend on karyotype (p = 0.71) or age at ERT initiation (p = 0.28). There were no differences in ΔhSDS during ERT (p = 0.63) between the two age groups (ERT ≤14 and >14 years). CONCLUSION The presented easy-to-use fixed-dose regimen for late-onset puberty induction allowed for a satisfactory rate of achieving subsequent puberty stages and did not influence the growth potential.

Abstract
OBJECTIVE The risk of autoimmune diseases (AD) in patients with Turner Syndrome (TS) is twice higher than in the general female population and four times higher than in the male population. The causes of the increased incidence of AD in TS are still under discussion. We hypothesized the presence of a specific humoral, cellular, and regulatory T cell (Treg) immunity profile which predisposes to AD, disorders of immunity, and disorders of immune regulation. METHODS The study encompassed 37 girls with TS and with no signs of infection. The control group included 11 healthy girls with no hormonal disorders. A medical history focused on AD and immunity disorders was taken from all participants. The levels of: immunoglobulins IgG, IgA, IgM, total lymphocytes, lymphocytes subpopulations CD3+, CD4+, CD8+, CD19+, natural killer cells, Treg cells (CD4+ CD25+ CD127- FOXP3+), anti-inflammatory cytokines (interleukin-10, transforming growth factor-β), anti-nuclear antibodies, glutamic acid decarboxylase (GAD65 Abs), anti-thyroid peroxidase (anti-TPO Ab), and anti-thyroglobulin (anti-TG Ab) autoantibodies were determined in each participant. RESULTS The mean age and BMI in the TS group and in controls were comparable (11.9 ± 4.1 vs. 12.5 ± 4.0 years; 19.2 ± 3.4 vs. 19.7 ± 4.6, p > 0.05). Mean hSDS was significantly higher in controls (-2.2 ± 0.9 vs. -0.4 ± 1.5, p < 0.0001). AD and recurrent otitis media with complications were previously confirmed in 9 (24.3%) and 10 (27.0%) girls with TS. The TS group had significantly lower levels of IgG (p = 0.02), lower%CD4 (p < 0.001) and a significantly lower CD4:CD8 ratio than the controls (p < 0.001). There were no differences in mean Treg% between girls with TS and healthy controls. However, comparing Treg% between the TS group with coexisting autoimmunity and the remaining participants, a statistically significant difference was observed (2.09 ± 0.5 vs. 2.77 ± 1.6, p = 0.048). Patients with iXq had lower CD4% and more frequently had positive anti-TPO Ab and anti-TG Ab compared to the remaining girls with TS and controls (p = 0.001, p < 0.001, p = 0.01). CONCLUSION TS predisposes to AD, especially if associated with coexisting iXq. Our preliminary findings show that patients with TS may present a specific profile of humoral and cellular immunity markers, different from healthy girls.

Abstract
STUDY OBJECTIVE The objective of this study was to evaluate whether body weight status and clinical hyperandrogenism may influence social competencies and psychological gender features in adolescent girls. DESIGN AND PARTICIPANTS In 104 adolescent girls, psychological gender inventory (PGI) and social competencies questionnaire (SCQ) (assessing social abilities in three aspects: intimacy (I), social exposure (SE), and assertiveness (AS)) were performed. Subjects were divided into four subgroups: G1-24 nonobese girls without hyperandrogenism, G2-18 obese girls without hyperandrogenism, G3-30 nonobese hyperandrogenic girls, and G4-32 obese girls with hyperandrogenism. RESULTS There were no significant differences in all parts of SCQ and PGI between the study and control groups. The feminine woman type dominated in all groups; in G3 and G4, masculine woman type appeared more often than in G1 and G2 (13.3% and 12.5% versus 4.0% and 0.0%, resp.). In G4, positive relationship between BMI z-score and SCQ (r = 0.4, p = 0.03) was found. In G1, the relationship was opposite (r = -0.5, p = 0.03). Hirsutism correlated negatively with SCQ (r = -0.5, p = 0.02), I (r = -0.5, p = 0.02), and AS (r = -0.5, p = 0.02) only in G1; in other groups, this relationship was insignificant. In G4, higher testosterone level was associated with lower SCQ (r = -0.5, p = 0.008) and AS (r = -0.5, p = 0.003). In G2, testosterone concentration correlated positively with SCQ (r = 0.6, p = 0.01), SE (r = 0.5, p = 0.02), and AS (r = 0.6, p = 0.02). CONCLUSION In adolescent girls, neither body weight nor clinical features of hyperandrogenism seem to be the source of evaluated disorders in psychological functioning.

Abstract
Turner syndrome is the most common example of hypergonadotropic hypogonadism resulting from gonadal dysgenesis. Most patients present delayed, or even absent, puberty. Premature ovarian failure can be expected even if spontaneous menarche occurs. Laboratory markers of gonadal dysgenesis are well known. The choice of optimal hormone replacement therapy in children and adolescents remains controversial, particularly regarding the age at which therapy should be initiated, and the dose and route of estrogen administration. On the basis of a review of the literature, we present the most acceptable schedule of sex steroid replacement therapy in younger patients with Turner syndrome.

Abstract
CONTEXT The profile of urinary steroids as measured by gas chromatography-mass spectrometry defines a subject's "steroidal fingerprint." OBJECTIVE Here, we clustered steroidal fingerprints to characterize patients with nonsyndromic childhood obesity by "steroid metabolomic signatures." HYPOTHESIS Nonsyndromic obesity is a symptom of different diseases and conditions, some of them will have their own signature. DESIGN A total of 31 steroid metabolites were quantified by gas chromatography-mass spectrometry, and their excretion rates were z-transformed. Using MetaboAnalyst 3.0, we divided the subjects into 5 distinctive groups by k-means clustering. Steroidal fingerprints and clinical/biochemical data of patients in each cluster were analyzed. PATIENTS A total of 87 obese children (44 females), aged 8.5-17.9 years, were clinically characterized, and their 24-hour urine was collected. RESULTS Cluster 1 (n = 39, 21 females) had normal steroid profile. Cluster 2 (n = 20, 11 females) showed mild, nonspecific elevation of C19 and C21 steroids, females' resistance to polycystic ovary morphology, and hirsutism. Cluster 3 (n = 7 female), with relative 21-hydroxylase insufficiency, was characterized by partial or full polycystic ovary syndrome. Cluster 4 (n = 4 males), showed markedly elevated C21 steroids and imbalance in the 11β-hydroxysteroid dehydrogenase system, higher insulin, increased frequency of glucose/insulin index more than 0.3, γ-glutamyl transpeptidase activity, systolic blood pressure, and tendency to liver steatosis. Cluster 5 (n = 17, 5 females) had elevated dehydroepiandrosterone and 17-OH-pregnenolone metabolites, suggesting 3β-hydroxysteroid dehydrogenase insufficiency but no clinically unique phenotype. Z-score body mass index values were not significantly different between the clusters. CONCLUSIONS We defined a novel concept of disease-specific steroid metabolomic signature based on urinary steroidal gas chromatography-mass spectrometry. Clustering by software designed for metabolic data analysis reclassified childhood obesity into 5 groups with distinctive signatures; groups require further definition and may require cluster-specific therapeutic strategies.

Abstract
Objective. To compare body composition parameters in short children with severe versus moderate and no growth hormone deficiency (GHD). Design and Method. 61 children (40 boys) were studied. Height SDS, BMI Z-score, waist/height ratio (W/HtR), and body composition parameters (BIA) as fat tissue (FAT%), fat-free mass (FFM%), predicted muscle mass (PMM%), and total body water (TBW%) were evaluated. GH secretion in the overnight profile and two stimulation tests and insulin-like growth factor 1 (IGF-1) level were measured. Results. Overall, in 16 (26%) moderate (7.0 > peak GH < 10 ng/mL) and in 11 (18%) severe (GH ≤ 7.0 ng/mL) GHD was diagnosed. In children with sGHD BMI Z-score, W/HtR and FAT% were significantly higher, while FFM%, PMM%, and TBW% were significantly lower versus mGHD and versus noGHD subgroups. No significant differences between mGHD and noGHD were found. There were no differences in height SDS and IGF-1 SDS between evaluated subgroups. Night GH peak level correlated significantly with FAT%, FFM%, PMM%, and TBW%, (p < 0.05) in the entire group. Conclusions. Only sGHD is associated with significant impairment of body composition. Body composition analysis may be a useful tool in distinguishing between its severe and moderate form of GHD.

Abstract
The main purpose of our retrospective study was to evaluate the medical care of the patients with subclinical hypothyroidism (sHT) and to investigate the rationale for administering L-thyroxine (LT-4) to young sHT patients. Patients and Methods. Based on a retrospective review of the charts of 261 patients referred to the Endocrinology Outpatient Clinic between 2009 and 2014 with suspicion of sHT, 55 patients were enrolled for further analysis. Data collected was baseline age, anthropometric measurements, serum TSH, fT4, fT3, anti-thyroid autoantibodies, positive family history, absence/presence of clinical symptoms, length of follow-up, and data concerning LT-4 therapy (therapy: T1; no therapy: T0). Results. T1 encompassed 33 (60.0%) patients. There were no differences between T1 and T0 (p > 0.05) with regard to age, TSH concentrations, BMI Z-score, and hSDS values, though follow-up was longer in T1 (p < 0.01). Four (11.8%) children in T1 and none in T0 had a positive family history of thyroid disorders. Fifteen (68.2%) patients in group T0 became euthyroid. One (1.8%) girl (T1) developed overt hypothyroidism. Conclusions. A small percentage of patients can proceed to overt hypothyroidism. Only positive family history seemed to influence the decision to initiate LT-4 therapy. Further prospective studies are warranted in order to establish treatment indications, if any, and the mean recommended dosage of LT-4.

Abstract
Study Objectives. The study aim was to evaluate whether hyperandrogenemia in adolescent girls with type 1 diabetes mellitus (T1DM) may adversely influence lipid profile. Design and Participants. Lipid levels in 16 diabetic girls with biochemical hyperandrogenemia (T1DM-H) aged 16.3 ± 1.2 years were compared to 38 diabetic girls with normal androgen levels (T1DM-N) aged 15.8 ± 1.2 years. 15 healthy girls served as controls (CG). In all patients, anthropometric measurements were done, and androgens and SHBG were assessed. Results. In T1DM-H, total cholesterol (TC) and low density cholesterol (LDL-ch) were significantly higher than in CG (196.1 ± 41.2 versus 162.7 ± 31.7 mg/dL, p = 0.01; 117.3 ± 33.1 versus 91.3 ± 27.8 mg/dL, p = 0.01, resp.). Their LDL-ch, non-high density cholesterol (non-HDL-ch) concentrations, and LDL/HDL ratio were also significantly higher than in T1DM-N (117.3 ± 33.1 versus 97.7 ± 26.7 mg/dL, p = 0.03; 137.3 ± 42.9 versus 113.3 ± 40.4 mg/dL, p = 0.04; 2.8 ± 3.7 versus 1.6 ± 0.5, p = 0.04, resp.). In stepwise multiple linear regression, free androgen index (FAI) and waist-to-hip ratio (WHR) were associated with TC (R (2) = 0.4, p < 0.0006), non-HDL-ch (R (2) = 0.4, p < 0.0003), and LDL-ch (R (2) = 0.4, p < 0.0008). Triglycerides and LDL/HDL ratio were (R (2) = 0.7, p < 0.0001, R (2) = 0.6, p < 0.0003 resp.) related to testosterone, FAI, WHR, and mean HbA1c. Conclusion. Lipid profile in diabetic adolescent girls is adversely influenced by the androgens level, particularly in the group with higher WHR and poorer glycemic control.

Abstract
Although subclinical hypothyroidism (SH) is a common clinical problem, its diagnosis tends to be incidental. According to the definition, it should be asymptomatic, only detectable by screening. The presence or coincidence of any symptoms leads to L-thyroxine treatment. The clinical presentation, especially in younger patients with subclinical hypothyroidism, is still under dispute. Accordingly, the aim of this paper was to review the literature from the past seven years. The literature search identified 1,594 potentially relevant articles, of which 24 met the inclusion criteria. Few studies focus on the symptomatology of subclinical hypothyroidism, and most of them analyzed a small number of subjects. A significant correlation was found by some authors between subclinical hypothyroidism and a higher risk of hypertension, dyslipidemia, and migraine. No evidence of the impact of subclinical hypothyroidism on weight, growth velocity, and puberty was revealed. As the quality of most studies is poor and no definite conclusions can be drawn, randomized, large-scale studies in children and adolescents are warranted to determine the best care for patients with SH.

Abstract
Objective. The study aim was to analyze whether anthropometrical parameters and TSH values in obese children with isolated subclinical hypothyroidism (IsHT) treated with levothyroxine (LT4) and weight reduction program differ from those managed by dietary and behavior counselling only. Material and Methods. 51 obese children with IsHT, who were treated according to the same weight reduction program, were retrospectively analyzed. They were divided into two groups: Group 1, n = 26, and Group 2, n = 25, without or with LT4 therapy, respectively. Changes in anthropometrical (delta BMI z-score) and hormonal (delta TSH) status were analyzed at the first follow-up visit. Results. In both groups significant decrease of TSH and BMI z-score values were noted. TSH normalized in 80.9% of children from Group 1 versus 90.5% from Group 2, p = NS. Delta BMI z-score was insignificantly higher in Group 1 compared to Group 2. Delta TSH was significantly related to initial TSH level in children treated by lifestyle intervention program only. Conclusions. In obese children with sHT dietary-behavioral management intervention contributed to reduction of body mass index, irrespective of levothyroxine use. This finding suggests that moderately elevated levels of TSH are a consequence rather than cause of overweight and pharmacological treatment should be avoided.

Abstract
Transition in health care for young patients with Turner's syndrome (TS) should be perceived as a staged but uninterrupted process starting in adolescence and moving into adulthood. As a condition associated with high risk of short stature, cardiovascular diseases, ovarian failure, hearing loss and hypothyroidism, TS requires the attention of a multidisciplinary team. In this review paper, we systematically searched the relevant literature from the last decade to discuss the array of problems faced by TS patients and to outline their optimal management during the time of transfer to adult service. The literature search identified 233 potentially relevant articles of which 114 were analysed. The analysis confirmed that all medical problems present during childhood should also be followed in adult life. Additionally, screening for hypertension, diabetes mellitus, dyslipidaemia, and osteoporosis is needed. After discharge from the paediatric clinic, there is still a long way to go.

Abstract
OBJECTIVE To determine and compare attitudes, skills, and practices in childhood obesity management in 4 European countries with different obesity prevalence, health care systems, and economic situations. METHODS A cross-sectional survey was distributed to primary health care providers from France, Italy, Poland, and Ukraine. The questionnaire was returned by 1119 participants with a response rate of 32.4%. RESULTS The study revealed that most of the primary health care providers were convinced of their critical role in obesity management but did not feel sufficiently competent to perform effectively. The adherence to recommended practices such as routine weight and height measurements, BMI calculation, and plotting growth parameters on recommended growth charts was poor. Most primary health care providers recognized the need for continuing professional education in obesity management, stressing the importance of appropriate dietary counseling. CONCLUSIONS The study underlines insufficient implementation of national guidelines for management of obesity regardless of the country and its health system. It also makes clear that the critical problem is not elaboration of guidelines but rather creating support systems for implementation of the medical standards among the primary care practitioners.

Abstract
For Turner syndrome (TS) patients, smooth transition from pediatric to adult health care is a critical point. The study objective was to evaluate the medical follow-up of young women with TS in one clinical center 3 years after the latest guidelines had been introduced by the TS Study Group. A questionnaire study was performed in 59 TS adults selected from a database of 117 patients. Twenty-two of them, aged 23.0 ± 2.8 years, consented to participate. Nineteen responders (86.4%) were followed up by general practitioners who were not aware of the TS diagnosis in 14 (63.6%) cases. Eight (36.4%) were seen regularly by the relevant specialists. Adequate medical assessment varied from 5% (celiac serology) to 74% (gynecology assessment) and 82% (ear-nose-throat) of participants. None of the patients had undergone all of the recommended investigations according to recommendation. Height deficiency, body mass index, age at TS diagnosis and level of education did not correlate with the number of assessments performed (p = 0.687, p = 0.810, p = 0.641, and p = 0.568, respectively). Three years after the introduction of the current guidelines, medical follow-up in the transition phase is still inadequate. Improvement in transitional health care is warranted through better patient education, referring to physicians caring for adults with TS and better cooperation with general practitioners with wider popularization of the TS recommendations among them.

Abstract
OBJECTIVE Secular trend in childhood obesity is a well-known phenomenon, and it is important to monitor it in cross-sectional studies. The study aim was to estimate prevalence of obesity and overweight in Polish 7- to 9-year-old children and to compare the results with a French study based on the same protocol. RESEARCH METHODS AND PROCEDURES The study was conducted in 2001 according to the protocol of the European Childhood Obesity Group. Height and weight were measured, and BMI was calculated to define nutritional status in a randomly selected group of 2916 (1445 girls and 1471 boys) primary school children. Obesity and overweight were estimated according to International Obesity Task Force references with curve for obesity and overweight passing through 30 and 25 kg/m(2) at age 18, respectively. RESULTS Overweight (including obesity) was found in 15.4% of Polish children (in 15.8% of girls and 15.0% of boys) and obesity in 3.6% (3.7% of girls and 3.6% of boys) compared with 18.1% of overweight and 3.8% of obese children in French study. There was no significant difference in nutrition status between Polish and French children except for higher frequency of overweight in French 9-year-old boys. The same trend of decreasing overweight through age classes was observed in both populations. DISCUSSION The prevalence of obesity and overweight (including obesity) in prepubertal children estimated in two European countries according to the same protocol and using the same references showed little differences between the two populations despite higher prevalence of obesity in Polish than French adults.

Abstract
OBJECTIVE Clinical studies suggest that the thyroid autoantibodies and/or hypothyroidism are not present in Turner's syndrome (TS) patients before the age of 8 years and are more frequent in patients with the X isochromosome. The aim of the study was to analyze the dynamics of thyroid dysfunction in girls with TS. DESIGN 86 TS patients with a median age of 10.6 years were followed for 4.6 ± 3.0 years. OUTCOMES The prevalence of thyroid abnormalities increased from 25.5 to 50% during the follow-up. Finally, 31 (36%) patients had positive thyroid autoantibodies and 27 (31.4%) had subclinical hypothyroidism. Hashimoto's thyroiditis was diagnosed in 15 patients. Median age of developing thyroid antibodies and subclinical hypothyroidism was 14.1 and 14.8 years, respectively. The youngest hypothyroid patient was 1.8 years old and the youngest girl with positive anti-thyroid antibodies was 5.5 years old. Autoantibodies appeared mainly after the age of 13. The risk of developing subclinical hypothyroidism was greatest between 12 and 14 years of age. The prevalence of thyroid abnormalities was not related to the karyotype. CONCLUSIONS Thyroid autoimmunity and dysfunctions in TS may start early, their prevalence increases with age, independently of karyotype and without any clinical symptoms and signs.

Abstract
OBJECTIVE To assess the risk of cardiovascular disease on the basis of biochemical, echocardiographic, and 24-hour blood pressure (BP) monitoring parameters in adolescent girls with polycystic ovary syndrome (PCOS). DESIGN Cross-sectional study. SETTING Academic and research institution. PATIENT(S) Thirty-four obese and nonobese girls with PCOS were evaluated and compared with body mass index-matched girls with regular menses. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Androgens, gonadotropins, lipids, and fasting and oral glucose tolerance test-stimulated glucose and insulin concentrations were measured. Echocardiographic assessment and 24-hour BP monitoring were done. RESULT(S) Compared with obese controls, obese girls with PCOS had significantly higher 24-hour mean BP, day mean BP, day diastolic BP, and diastolic BP nighttime dip (75.5 ± 4.5 mm Hg vs. 71.7 ± 3.7 mm Hg; 78.2 ± 5.0 mm Hg vs. 73.6 ± 4.0 mm Hg; 67.6 ± 4.9 mm Hg vs. 63.7 ± 3.7 mm Hg; and 20.2% ± 5.2% vs. 15.0% ± 6.6%, respectively). Obese girls with PCOS had significantly higher night heart rate than obese controls (60.4 ± 5.6 beats per minute vs. 61.7 ± 4.8 beats per minute). Left ventricle end-diastolic (4.6 ± 0.3 cm vs. 4.2 ± 0.2 cm) and end-systolic diameter (3.0 ± 0.3 cm vs. 2.7 ± 0.2 cm) were also significantly higher in nonobese girls with PCOS than in nonobese controls; however, all values were still within the accepted range of normal limits. CONCLUSION(S) Higher night heart rate in obese girls with PCOS and higher day BP but preserved diastolic nocturnal dip in nonobese girls with PCOS may be regarded as early cardiovascular disease risk factors.

Abstract
OBJECTIVES The objectives of this study are to evaluate co-morbidities in patients with craniopharyngioma and to elaborate an interdisciplinary protocol of the follow-up. PATIENTS AND METHODS The group comprised 15 children (median age at the diagnosis, 10.1; mean follow-up period, 4 years). All patients had surgical resection of the tumour: gross total in seven, subtotal or partial removal in eight cases. Surgery was followed by radiotherapy in ten cases for tumour residue or progression. Sexual development and auxology were evaluated at diagnosis and during follow-up. Hormones were determined by chemiluminescent immunometric assays. Antidiuretic hormone dysfunction was diagnosed on the grounds of clinical symptoms, water-electrolyte balance, urine specific gravity, and serum osmolality. Metabolic control was monitored by levels of glucose, insulin, lipids, and transaminases; insulin resistance was expressed by homeostatic model assessment (HOMA) index. RESULTS At diagnosis, median height standard deviation score (hSDS) was -1.6 (five children being short-statured). Median change hSDS for the whole follow-up was 1.2 (four children decelerating growth). Diabetes insipidus was diagnosed in eight (within 0-1.8 years of the follow-up), hypocorticolism in eight, and hypothyroidism in 12 subjects (within 0-3.75 years for both endocrinopathies). Four patients required sex hormone replacement therapy. At diagnosis, five children were overweight; during follow-up, only four children sustained normal body mass index. Hypertransaminasaemia was found in three, dyslipidaemia in 11, and hyperinsulinaemia in seven patients (with elevated HOMA in four cases). CONCLUSIONS On the grounds of these observations, the management of craniopharyngioma in our institution includes repeated hormonal and metabolic assays in chosen time intervals. Early detection of co-morbidities and their management involves interdisciplinary team.

Abstract
The study assessed 3.5-year treatment with continuous subcutaneous insulin infusion (CSII) in well-controlled children with duration of type 1 diabetes mellitus longer than 1 year. Following groups were observed: the CSII group-40 children and the multiple injections (MDI) group-36 patients (age-matched, the mean of 6.5+/-2.1 and 7.1+/-1.8 years, respectively). At the onset of the follow-up both groups were comparable in age, HbA1c, daily insulin requirement (DIR), body weight, height and BMI. They were followed from the start, and every 6 months in relation to DIR, HbA1c, acute complications (DKA, hypoglycaemia) and physical development. Mean HbA1c and DIR for the whole study period were lower in the CSII versus MDI group (6.90+/-0.54 vs 7.22%+/-0.16 and 0.75+/-0.16 vs 0.88+/-0.13 U/kg/d; p<0.05). HbA1c was lower in the CSII versus MDI group in months 6 and 42 (6.95 vs 7.29%, and 6.91 vs 7.43%, respectively; p<0.05). DIR was significantly lower at most intervals in the CSII group. No significant differences regarding number of complications and anthropometry were found. CSII allows for near-normal metabolic control and lower insulin requirement comparing to the MDI method. CSII is safe treatment, assuring harmonious child's development.

Abstract
UNLABELLED The rapid rising prevalence of childhood obesity is related to increased risk of obesity-related diseases during adulthood. The aim of the present study was to review the data concerning the prevalence of metabolic syndrome (MS) in European children and adolescents (Part 1) and to determine and compare the prevalence of MS among overweight and obese children, and adolescents in five European countries using four MS definitions (Part 2). In total, 1 241 European obese children from five different countries (France: n =283, Greece: n =145, Italy: n =274, Poland: n =90, and Hungary: n =449) were studied for MS according to the definition of Ferranti et al., the World Health Organisation, the National Cholesterol Education Program and the International Diabetes Federation. We used age- and sex-specific cut-off values for the diagnosis of high blood pressure and increased waist circumference. The prevalence of MS was 35.7%, 31.4%, 20.3%, and 16.4%, respectively, according to the above-mentioned definitions. Only 6.3-8.8% of obese adolescents were free from any risk factors and the clustering of three risk factors or more was very high: 20.3-35.7% (depending on the type of definition). A total of 12.2% of children had MS and 55.8% were free from MS according to all four definitions. CONCLUSIONS The prevalence of MS is high among European obese children whatever criteria are used. There is an urgent need to achieve consensus concerning the definition of MS in adolescents and children.

Abstract
BACKGROUND Autosomal dominant familial neurohypophyseal diabetes insipidus (adFNDI) is a rare disease with symptoms of polydipsia, polyuria and dehydration caused by arginine vasopressin deficiency. Disease onset is within infancy or adolescence. A variety of disease-causing mutations of the arginine vasopressin neurophysin II gene (AVP) on chromosome 20p13 have been described. METHODS Two Polish families with adFNDI were screened for mutations. Processing of wild-type (WT) and mutant AVP was monitored using immunocytochemical methods in stably transfected Neuro2A cells. AVP secretion into the cell culture supernatant was investigated with an enzyme immunoassay. RESULTS In the first family a heterozygous p.G96D mutation was identified. Some patients additionally carried a novel heterozygous mutation p.A159T. The second family presented with a heterozygous mutation p.C98G. Confocal laser microscopy unveiled accumulation of p.G96D and p.C98G prohormones in the cellular bodies, whereas WT and p.A159T prohormones and/or processed products were located in the tips of cellular processes. Reduced levels of AVP in supernatant culture medium of p.G96D and p.C98G transfected cells in comparison to p.A159T and WT cells were found. CONCLUSIONS We conclude that the p.G96D and p.C98G mutations cause adFNDI in the two reported families. The sequence variant p.A159T does not seem to have disease-causing effects.

Abstract
BACKGROUND A 15-year-old girl presented to our clinic with short stature and delayed puberty. On examination her height was 139.3 cm, which is 13.2 cm below the 3(rd) percentile on a standard growth chart, and she had no clinical signs of puberty. A number of typical features of Turner's syndrome were found, including a short webbed neck, cubitus valgus, shield chest, multiple pigmented nevi, lymphedema, epicanthus and micrognathia. INVESTIGATIONS Plasma follicle-stimulating hormone and luteinizing hormone levels were increased. A pelvic ultrasound demonstrated a small uterus, but the ovaries could not be visualized. The patient's bone age was 12-13 years. A horseshoe kidney was seen on renal ultrasound and an echocardiography revealed aortic coarctation. The 45,X karyotype confirmed the diagnosis. DIAGNOSIS Turner's syndrome. MANAGEMENT Growth hormone therapy (1 IU/kg/week; approximately 0.05 mg/kg/day) was started together with oxandrolone (0.05 mg/kg/day) and transdermal estrogen. The dose of estrogen was gradually increased from 12.5 microg/day to 25.0 microg/day and then to 50.0 microg/day over a period of 12 months. Growth hormone and oxandrolone were withdrawn after 1 year, when the patient's epiphyses had fused. Hormonal replacement therapy with estrogens was continued and the patient has reached stage 3 of pubertal development and a final height of 148.5 cm.

Abstract
CONTEXT The phenotype in Turner syndrome (TS) is variable, even in patients with a supposedly nonmosaic karyotype. Previous work suggested that there were X-linked parent-of-origin effects on the phenotype. HYPOTHESIS The TS phenotype is influenced by the parental origin of the missed X chromosome. DESIGN This was a multicenter prospective study of TS patients and both their parents, determining parental origin of the X-chromosome, and characterizing the clinical phenotype. PATIENTS AND METHODS Eighty-three TS patients and their parents were studied. Inclusion criteria were TS with karyotype 45,X or 46Xi(Xq). Four highly polymorphic microsatellite markers on the X-chromosome DMD49, DYSII, DXS1283, and the androgen receptor gene and three Y chromosome markers, SRY, DYZ1, and DYZ3. OUTCOME MEASURES The study determined the correlation between the parental origin of the X chromosome and the unique phenotypic traits of TS including congenital malformations, anthropometry and growth pattern, skeletal defects, endocrine traits, education, and vocation. RESULTS Eighty-three percent of 45,X retained their maternal X (X(m)), whereas 64% 46Xi(Xq) retained their paternal X (X(p), P < 0.001). Kidney malformations were exclusively found in X(m) patients (P = 0.030). The X(m) group had lower total and low-density lipoprotein cholesterol (P < 0.003), and higher body mass index sd score (P = 0.030) that was not maintained after GH treatment. Response to GH therapy was comparable. Ocular abnormalities were more common in the paternal X group (P = 0.017), who also had higher academic achievement. CONCLUSIONS The parental origin of the missing short arm of the X chromosome has an impact on overweight, kidney, eye, and lipids, which suggests a potential effect of an as-yet-undetermined X chromosome gene imprinting.

Abstract
OBJECTIVE To assess the frequency of obesity, overweight and underweight (thinness) in Polish 7-9-year-old children using a population specific definition as compared to the French, US and IOTF references based on body mass index (BMI). DESIGN Height and weight were measured and BMI was calculated in a randomly selected representative sample of 7-9-year-old Polish children (N = 2916; 1445 girls; 1471 boys) to define their nutritional status. Overweight (including obesity) was estimated according to four and underweight (thinness) according to three definitions Polish national references; French references; United States references and International Obesity Task Force references. RESULTS According to Polish, French, U.S. and IOTF references overweight (including obesity) was found in 12.1, 14.3, 20.7 and 15.4% of children, respectively; 3.5, 9.4 and 3.6% of children were obese according to national, U.S. and IOTF references, respectively while underweight (thinness) was present in 6.9, 2.6 and 4.2% of children according to Polish, French and U.S. references, respectively. A trend of decreasing overweight and increasing underweight through age classes was observed. CONCLUSION The rates of underweight (thinness), overweight and obesity in Polish 7-9-year-old children calculated according to the national, French, U.S. and IOTF references were significantly different. Therefore even if the IOTF reference is considered superior for international epidemiological studies, population specific standards should probably coexist for clinical practice.

Abstract
BACKGROUND The researchers and clinicians need to gain a better understanding of the social and environmental contexts by which childhood obesity is becoming a growing problem of twenty-first century and develop more efficacious methods of prevention and treatment. METHODS Summary of the actions and achievements of the European Childhood Obesity Group (ECOG) since its foundation in 1991 until the 16th anniversary. Review of the sessions of the 16th ECOG workshop devoted to epidemiology, prevention, risk factors, comorbidities and treatment of childhood and adolescent obesity. RESULTS Meta-analysis of epidemiological data on childhood obesity in Europe underscores an urgent need of preventive actions in which general practitioners may play an important role. Media should get actively involved in promotion of healthy lifestyle. Metabolic syndrome, non-alcoholic steatohepatitis, diabetes type 2 and sleep apnoea syndrome are becoming more common in obese adolescents. In morbid obesity with severe comorbidities, more aggressive ways of treatment may be considered. CONCLUSIONS European Childhood Obesity Group members should get actively involved into targeted prevention and intervention project to promote healthy lifestyle and successful weight control.

Abstract
BACKGROUND/AIMS According to FDA-approved guidelines, boys whose height predictions fall to 160 cm or less are considered for treatment with recombinant growth hormone (rGH). The aim of this study was to analyze the value of different height prediction methods by accurately identifying those boys with constitutional delay of growth and puberty (CDGP) in whom final height (FH) prognosis was poor (<or=160 cm) and who might therefore be candidates for this treatment modality. METHODS In 69 boys with CDGP diagnosed at a mean age of 14.9 +/-1.2 years, FH prediction was calculated by means of Bayley-Pinneau (BP), Roche-Wainer-Tissen (RWT), Tanner-Whitehouse II (TWII) and target height (TH) methods. At the age of 22.6 +/- 3.5 years their height was remeasured and the accuracy of height prediction was analyzed. RESULTS In 6 men (8.7%) measured FH was <or=160 cm. Depending on the prediction method, different individual patients within the 14- to 16-year age range would have been candidates for rGH treatment. The BP method would have recruited 8 subjects of whom only 3 had FH <or=160 cm (sensitivity 50%, specificity 92%). The RWT and TW II methods identified only one recruit, and this patient did achieve FH <or=160 cm (sensitivity 17%, specificity 100%). None of the 8 subjects with FH <or=160 cm would have qualified for GH treatment using the TH method. In three boys none of the four methods predicted their final height <or=160 cm. CONCLUSION Although some boys with CDGP may be considered the candidates for rGH treatment according to FDA recommendations, none of the available methods of prediction are sufficiently sensitive to reliably recruit 14- to 16-year-old boys whose final height will fall at or below 160 cm.

Abstract
Growth charts, which describe the natural course of growth in Turner syndrome (TS) patients, are commonly used in studies in lieu of control groups. While analysing data, various charts produce different final height estimations and height-gain predictions. The choice of an appropriate chart should be the first task when assessing effects of growth hormone treatment. The purpose of this study was to establish the most appropriate growth chart for the subsequent analysis of growth rate in the patients with TS observed initially for a short time without treatment in our clinic. We propose the criteria that a standardised chart should meet. The obtained height-standardised values (height standard deviation score -- Ht SDS) should represent normal distribution with a mean of 0 and standard deviation of 1; their initial mean value and mean change in these values during observation without treatment should not be different from 0. We studied 62 untreated girls with TS using three different growth charts. The values of Ht SDS based on the Lyon chart showed a significant difference from normal distribution (p < 0.05). Only the mean value of an initiaent from 0 (p = 0.088). The mean change of the Ht SDS value based on Lyon and Ranke charts during the follow-up period was not statistically different from 0 (p > 0.05), whereas the difference was statistically significant when the Wisniewski chart was used. Only the Ranke chart correctly characterised TS girls in our clinic. This analysis indicates the importance of careful selection of an appropriate growth chart for an observed population, before applying it to evaluate the effects of hormonal therapy.

Abstract
AIM The aim of the study was to review the published and unpublished data on type 2 diabetes in European children in order to determine how common this problem is in the dominantly Caucasian population. METHODS The MEDLINE database was searched and a questionnaire was distributed among European Childhood Obesity Group (ECOG) representatives from 16 countries. RESULTS One hundred and eighty-four children with type 2 diabetes were diagnosed in Europe, 144 of them of Caucasian origin. The majority of them were overweight females and, had positive family history for type 2 diabetes mellitus. CONCLUSION Because of the significant rates of type 2 diabetes in Europe, screening for it in obese children and adolescents is highly recommended.

Abstract
UNLABELLED The efficacy of growth promoting hormonal therapy is assessed on the basis of growth rate as well as bone age progression until the patients reach their final height. The aim of our study was to investigate which hormonal therapy influences in most appropriate way height velocity and bone age progression in patients with Turner syndrome (TS) and to establish the optimal age to initiate treatment. Patients were divided into five groups according to the type of hormonal therapy: 1) 11 patients treated with growth hormone (GH); 2) 18 patients treated with GH and oxandrolone (Ox); 3) 7 patients treated with GH, Ox and estrogens (E); 4) 6 patients treated with OX and E; and the control group (Group 0) of 62 untreated patients. The patients height was expressed in hSDS calculated on the basis of growth chart for patients with TS (hSDST). Bone age (BA) was assessed according to Greulich-Pyle method. RESULTS The mean values of deltahSDST in the first and second year of therapy in individual groups were significantly different. The difference resulted from significantly higher value of deltahSDST in group treated with GH+Ox. Analysis of regression between deltaCA and deltaBA revealed regression coefficients alpha of equation deltaBA= alpha x deltaCA: in group 0: 0.817; group GH: 1.233; group GH+Ox: 0.861; group GH+Ox+E: 0.997; group Ox+E: 1.141. There was significant difference between regression coefficients in studied groups. It resulted from significantly higher value of alpha in group treated with GH than in a group 0 and treated with GH+Ox. Only group treated with GH+Ox showed a significant negative correlation between baseline CA and deltaBA during the therapy. We can conclude that all regimens of hormonal therapy improved height in our patients but the highest increase of height during the therapy and the smallest progression of the bone age in the same time were observed in patients treated with GH+Ox.

Abstract
OBJECTIVE Treatment of benign thyroid tumors with percutaneous ethanol injections (PEI) is an alternative to radioiodine and surgery. This procedure causes a release of large amounts of denaturated thyroglobulin within the gland which may become an autoantigen, triggering the mechanism of autoimmunization. The aim of the study was to investigate whether ethanol injections can induce increased levels of thyroid autoantibodies and tumor necrosis factor-alpha (TNF-alpha) in patients with nonfunctioning or pre-toxic thyroid nodules. MATERIAL AND METHODS Thirty-four patients (31 F, 3 M) with single benign thyroid tumors were enrolled, 23 (20 F/3 M) with nonfunctioning nodule (group 1) and 11 (F) with pre-toxic nodule characterized by normal free thyroid hormones and low TSH (group 2). Under sonographic guidance, sterile 96% ethanol solution was injected into thyroid nodules at 2-week intervals up to a dose of 0.7-1.0 ml of ethanol per 1.0 ml nodule volume. TSH, fT4, thyroglobulin antibodies and thyroperoxidase antibodies as well as TNF-apha levels were assessed prior to alcohol administration and 3, 6, and 12 months after the end of treatment. RESULTS PEI treatment decreased tumor volume by 75.8% in group 1 and by 80.4% in group 2, and normalized TSH level in 90.9% of patients with pre-toxic nodules. No statistically significant differences in thyroperoxidase antibodies and TNF-alpha levels were observed during the study period in both groups. Thyroglobulin antibody levels increased significantly 6 months after treatment in both groups, but returned to the baseline levels after 12 months. No significant difference in peak thyroglobulin antibody levels between the two groups was seen. CONCLUSION PEI procedure is a safe method for treating nonfunctioning and pre-toxic thyroid nodules since this treatment reduces tumor size significantly without inducing long-lasting autoimmune reactions in the thyroid gland. Transient increase in thyroglobulin antibodies indicates that this procedure should be performed with caution in patients at risk of autoimmune diseases.

Abstract
Moyamoya disease is a rare cerebrovascular disorder which, according to a few literature reports, can coexist with hypothalamic-pituitary dysfunction. We report a 16 year-old boy referred to our Department because of short stature and headaches. He additionally, at admission, presented discrete facial dysmorphy, bruxism, luxation of temporomandibular joint and cryptorchidism. The height was 146 cm (-4.3 SDS); the sexual development was P2G2A1 and the bone age 11.5 years. The intellectual development was normal. No focal neurological deficits were observed. Based on baseline and stimulated hormonal values, isolated growth hormone deficiency was diagnosed. Malformation of the cerebral vessel was suspected on magnetic resonance imaging and upon angiocomputed tomography and panangiography, a picture suggesting moyamoya disease was obtained. Growth hormone has been administered with daily injections at the dose of 0.025 mg/kg/24h, and the first year height velocity was 12 cm/yr. No adverse events resulting from the treatment have been noted so far. This case indicates that GH deficiency may be associated with moyamoya disease, possibly resulting from chronic cerebrovascular insufficiency.

Abstract
In a country with a high cardiovascular mortality rate, lipid profiles were studied in 929 adolescents (440 from affected and 489 from non-affected families for cardiovascular disease and hypercholesterolaemia). In 334 children with elevated or borderline total cholesterol level, lipid profiles were re-measured after a 1-y period. In boys from affected families, in contrast to boys from non-affected families, significantly higher total cholesterol levels (4.36 +/- 0.81 vs 4.19 +/- 0.78 mmol/L, p < 0.05) and LDL-C level (2.1 +/- 0.72 vs 1.89 +/- 0.79 mmol/L, p < 0.05) and significantly lower HDL-cholesterol levels (1.81 +/- 0.34 vs 1.93 +/- 0.38 mmol/L, p < 0.05) were found. The odds ratio for being in the most unfavourable decile for LDL-cholesterol was significantly higher for girls from affected families (2.17, p = 0.02). A relatively high HDL-C level as well as a favourable TC/HDL-C ratio was demonstrated in all groups, being lowest in boys from affected families. A significant correlation was found between baseline lipids and their values re-measured after 1 y. It is concluded that (1) adolescents with a positive family history are at increased risk for unfavourable lipid profile, (2) adolescents with elevated total cholesterol and LDL-cholesterol levels remain hypercholesterolaemic after a 1-y period and are therefore candidates for further biochemical and clinical monitoring, and (3) children with elevated total cholesterol may not be at high risk for cardiovascular disease owing to the favourable TC/HDL-C ratio. The study results do not indicate that general cholesterol screening in Polish adolescents is necessary, as the proportion of children with elevated LDL-cholesterol is relatively low.

Abstract
The effect of ephedrine (E) and theophylline (T), administered alone and in combination (E/T), on weight loss, resting energy expenditure and post-heparin lipoprotein lipase activity in plasma (PHLA) and in adipose tissue (ATLP) were investigated in obese over-fed rats, who had been diet restricted (-40% of normal caloric intake) for three weeks. E, T and E/T significantly increased weight loss in all experimental groups as compared to the controls. Weight loss was achieved not only by preventing the adaptive fall in resting energy expenditure associated with diet restriction, but by raising it above basal level. The effect of E/T mixture was no greater than that of E or T alone. E, T and E/T administration increased PHLA in plasma while hypocaloric diet alone did not influence the activity of the enzyme. ATLP in the epididymal fat pads decreased insignificantly in all experimental groups, as well as in the controls. Serum cholesterol levels were not influenced by hypocaloric diet and by drug administration, but serum triglycerides increased significantly in E, T and E/T treated groups. The elevation of PHLA after ephedrine and/or theophylline administration was mostly due to an increase in the hepatic lipase (HL) level. This enzyme contributes to the removal of the atherogenic intermediate density lipoproteins from blood serum. The increased HL activity in drug-treated, diet-restricted obese rats may therefore play a role in the prevention of atherosclerosis.

Abstract
In order to assess the accuracy of pulmonary time-activity curves obtained at bedside with a single scintillation probe and Technetium-99m-labelled erythrocytes, pulmonary to systemic flow ratio (Qp:Qs) was calculated for radionuclide and hemodynamic investigations in 104 patients with suspected intracardiac left to right shunts. Cardiac catheterization confirmed the presence of shunts in 76 patients. Pulmonary time-activity curve was 100% sensitive, 88% specific, and 96% accurate in detecting the shunt. Correlation between the radionuclide and hemodynamic Qp:Qs was excellent (r = 0.93). Results were classified in four quantitative categories according to the Qp:Qs values. In 76 patients (73%) radionuclide and hemodynamic data fell in the same category. We conclude that radionuclide pulmonary time-activity curves generated with a scintillation probe is a reliable method in quantitative assessment of intracardiac left to right shunts.
