ACTA ENDOCRINOLOGICA (BUC)

Background. Craniopharyngiomas are benign but locally invasive tumours of the sellar region that arise from ectopic embryonic remnants of Rathke's pouch, affecting both children (adamantinomatous type -aCP) and adults (papillary type -pCP) and associated with significant morbidity. Objective. To study the clinical presentation of CRF as well as the posttreatment evolution of craniopharyngioma in children versus adults in a large mixed cohort. Material and methods. We performed a retrospective review of CRF patients evaluated in the National Institute of Endocrinology in Bucharest between 1990 and 2016. Results. A total of 107 patients (72 adults, 35 children) with a mean follow-up of 6.2 years were included. The presenting symptoms were mostly headache, visual impairment, symptoms of hypopituitarism, diabetes insipidus. Some symptoms or hormonal abnormalities were significantly more prevalent in the children group (p<0.05): nausea/ vomiting (47.8% vs 16.7%), photophobia (21.7% vs 5.6%), diabetes insipidus(28.5% vs 8.3%), GH deficiency (68.8% vs 17.1%). Impaired visual acuity (67.6%of cases) or visual fields (71.4%) were more frequent in adults compared to children (44.1%; 51.6%). The tumor dimensions were similar in both groups (3.05± 1.05 cm in children; 2.7± 1.07 cm in adults). Massive suprasellar extension reaching the third ventricle was frequently present in all cases. All cases underwent surgery but only a minority of those not cured received postoperative adjuvant radiotherapy. Frequent postoperative complications were: aggravation of the endocrine deficit (>80% of cases in both groups needed chronic replacement therapy), central diabetes insipidus (68.2% children, 34.3% of adults). Conclusions. Despite similar tumor dimensions and extension compared to adults, craniopharyngioma in children is more frequently associated with signs of intracranial pressure. The results and complications of treatment are similar in adults and children

Clinical manifestation of this diseases is sexual ambiguity. The authors present a pediatric\r\ncase with sexual ambiguity and karyotype 45, X/46, XY, the child of a HIV-positive mother receiving multiple antiretroviral treatments for a period of 16 years.

Background. Heart failure (HF) is a disease with a high prevalence in the elderly population. Problems posed by HF diagnosis and management within this special category validate the interest in studying ways to improve the quality and duration of life in these patients. Aim. To determine the prognostic accuracy of certain clinical and laboratory parameters and to predict mortality rates in elderly patients with HF. Study design. It is a cohort, analytical, prospective, observational, crosssectional study conducted between 2006- 2008. Data regarding patient survival over a period of six months were recorded from the moment of enrollment. Subjects and methods. The study group consisted of 177 patients of over 65 years of age admitted to geriatrics, internal medicine and cardiology units, diagnosed with HF. A series of clinical and laboratory data from these patients has been examined, including NT-proBNP and CRP. Results. CRP levels higher than 3.57 mg/dL determined a hazard ratio (HR) of 3.9 (CI95% 1 - 15.2, p=0.04), urea levels higher than 79 mg/dL determined a HR of 8.8 (CI95% 1.1 - 37.4, p=0.003) and NT-proBNP levels higher than 9370 pg/mL determined a HR of 18.6 (CI95% 5.2 - 66.2, p<0.001). After multiple comparison adjustments (Bonferroni correction), only urea and NT-proBNP remained independent variables predicting 6-month mortality in elderly patients with HF. Conclusion. High NT-proBNP and urea levels were independent predictors for mortality in elderly patients with heart failure.

The increase in prevalence of obesity in children is well known worldwide, with important implications for health.\r\nAim. To evaluate the growth patterns of normal weight, overweight, obese and underweight schoolchildren from western Romania, in order to understand how body mass is related to height gain.\r\nMaterial and method. A total of 3626 children aged 7-18 years, were examinated, between February 2010-June 2011. Children were classified as normal weight, underweight, overweight and obese, using IOTF criteria.\r\nResults. We present the growth curves in regard to BMI class and the comparison of the 50th percentile of each BMI class, in boys and girls separately. The period of significant height difference/year at the 50th percentile for each BMI class indicates that overweight and obese boys have important height gain between 11-14 years, while for underweight boys it is constant between 11-18 years. In overweight and obese girls, an important height difference/year is observed between 7-11 years, while in underweight group it is seen between 10-13 years.\r\nConclusions. In boys, increased BMI leads to taller young stature, delayed growth spurt, but similar height at age of 18 years, while in the underweight group we observed a prolonged growth spurt with increased height at 18 years. Increased BMI, in girls, resulted in early growth spurt and similar height at 18 years when compared to normal weight peers. Final height was independent of BMI in both girls and boys.

Context. Sodium-glucose co-transporter 2 inhibitors (SGLT2-I) are a new class of oral antidiabetic drugs. Objective. Side effects of drugs are frequently encountered with increasing use in clinical practice. Design/Subjects and Methods. We present a case with an unidentified body odor that has not been described yet in the literature as an adverse effect of SGLT2-I. Results. A 49-year-old female patient with Type 2 DM was applied to our clinic for routine control. She had been receiving sitagliptin/metformin 50/1000 mg b.i.d. Her fasting plasma glucose was 160 mg/dL and HbA1c was 8%. Empagliflozin 10 mg/day was added to therapy. The patient noticed that two weeks after starting empagliflozin treatment, she began to smell herself and felt a bad/foul odor was released from her body. The patient associated these complaints with the new drug(empagliflozin) stopped two weeks ago. She also stated that all these complaints had disappeared one week after stopping the medication and there were no complaints at the moment. Conclusions. Here we report an unidentified body odor as a potential empagliflozin-associated adverse event. There was a close temporal relationship between empagliflozin intake and the development and the occurrence of the described odor.

Background. The modern management of phenylketonuria (PKU) consists of generalized newborn screening (NBS) for hyperphenylalaninemia (HPA), confirmation of HPA in children detected in the NBS, introduction of dietary treatment in the first weeks of life, followed by monitoring the treatment of PKU for decades to maintain phenylalaninemia within the limits that will not affect the brain. The present study aimed to evaluate the usefulness of two chromatographic methodologies for determination of plasma Phe level in the routine management of PKU: the two dimensional thin layer chromatography (2D - TLC) and the high performance liquid chromatography (HPLC) procedures, respectively. Material and Methods. Samples of blood from 23 children with HPA detected by neonatal screening or with confirmed PKU who received treatment by low-Phe diet were analyzed to estimate the plasma Phe level by the two chromatographic procedures. Results. In case of three subjects the very low concentrations of plasma Phe could not be detected by the 2D - TLC methodology, since the spot was not visible on the chromatogram. In four patients the differences between the values of plasma Phe determined by the two methodologies are not statistically significant, while in fifteen subjects the differences are highly statistically significant. This is due to the greater errors that appear in the case of 2D - TLC methodology. In the range of concentrations of plasma Phe higher than 360 μmol/L (which is the cut-off value for HPA), although in four cases there were statistically significant differences in the level of plasma Phe determined by the two methodologies, the value obtained by the 2D - TLC methodology was high enough to influence the decision of changing the diet so that HPA is kept under control. In addition, the intense spot of Phe on the 2D - TLC chromatogram may be detected even by un unexperienced laboratory specialist. Conclusion. The HPLC procedure for measurement of plasma Phe level is very suitable to be used in the routine management of PKU. The 2D - TLC procedure may be accompanied by relatively high errors; however, it detects patients with severe PKU.

The anaesthetic management of pheochromocytoma is complicated and challenging. However, preoperative pharmacologic preparation, modern anaesthetic techniques and drugs associated with advanced monitoring in conjunction with the evolution of surgical techniques (open laparotomy to laparoscopic surgery and robotic approaches in the present day) improved significantly perioperative outcome, and intraoperative and postoperative hemodynamic stability. Although there are not randomised clinical trials to suggest one approach over another and there is a high international variability amongst intraoperative anaesthetic techniques, most management principles are still universal.

The role of osteocalcin in atherogenesis is unclear. We investigated the association between osteocalcin and carotid atherosclerosis in Chinese middle-aged and elderly male adults and further determined whether osteocalcin is independently associated with the carotid intima-media thickness (CIMT) in hyperglycemia subgroups. Subjects and methods. A total of 84 male participants (mean age, 59.13 years) were enrolled in groups of normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) according to the oral glucose tolerance test. A standard interview, anthropometric measurements and laboratory analyses were performed for each participant. Bilateral carotid intima–media thicknesses (CIMT) were measured using ultrasonography. The circulating osteocalcin was measured using quantitative enzyme immunoassay. Results. Both IGT and newly diagnosed T2DM groups had significantly lower osteocalcin levels compared with the NGT group (5.01 ± 0.68 μg/L, and 6.173 ± 0.68 ng/mL vs. 11.55 ± 0.57 μg/L, respectively). Multivariate linear stepwise regression analysis demonstrated that waisthip ratio(WHR) (standardized β = -0.408, P = 0.000), 2 hour plasma glucose after glucose load, (PPG) (standardized β = -0.235, P = 0.025), homeostasis model of assessment for insulin resistance index(HOMA-IR) (standardized β = -0.287, P = 0.004), and Glycosylated haemoglobin (HbA1c) (standardized β = -0.250, P = 0.015) were independently and inversely associated with serum osteocalcin in hyperglycemia subgroups; PPG(standardized β = -0.476, P = 0.015), osteocalcin(standardized β = -0.486, P = 0.001) were negatively associated with CIMT, while TG (standardized β = 0.647, P = 0.000) was positively associated with CIMT in T2DM. Conclusion. These results showed that osteocalcin is independently associated with carotid atherosclerosis in men with T2DM. It is tempting to suggest that osteocalcin may be implicated atherosclerosis.
