ACTA ENDOCRINOLOGICA (BUC)

Introduction. The prevalence of obesity has reached alarming levels in the European Union, including in Romania. Data on the prevalence of obesity is only available at the national populational level, but this may hide the increased levels in disadvantaged groups. The purpose of this study was to evaluate the prevalence of overweight and obesity in the Roma population in Southern Romania. Material and method. This cross-sectional, epidemiological, non-interventional study was conducted from March 2014 to May 2017 in several settlements from Calarasi County. Screening procedures included interviews about medical history, lifestyle, anthropometric and clinical measurements and fasting capillary glucose. Results. The study population consisted of 1120 adult subjects, of which 735 Roma. In Roma population group, the prevalence of underweight, normal weight, overweight and obesity was 4.5% (n=33), 25% (n=184), 25.3% (n=186) and 45.2% (n=332) respectively. In Romanian Caucasians group, the prevalence of underweight, normal weight, overweight and obesity was 2.3% (n=9), 20% (n=77), 33.8% (n=130) and 43.9% (n=169) respectively. Among the Romanian Caucasians significant predictors of obesity were a sedentary lifestyle and current smoking. The odds of being obese in Roma population were higher in sedentary lifestyle persons and lower in current smokers, with primary education, and in those living in rural settlements. The family history of obesity had a significant association with obesity only in Roma population. Conclusions. Our results confirm the need to implement prevention programs in high-risk populations due to the double burden of malnutrition, lack of medical education and preventive healthcare, low socio-economic level.

Context. The links between obesity and thyroid function or thyroid volume in children are still controversial with limited available data. Objective. This study aimed to examine thyroid function and volume in obese Turkish school-age children in comparison to normal-weight children. Design. Cross-sectional study. Subjects and Methods. One hundred obese children (47 boys, 53 girls; mean age 10.34±2.79 years) with a body mass index (BMI) above 95th percentile, and 100 normal-weight children (42 boys, 58 girls; 10.34±2.79 years) were included. The study parameters were BMI z score (Z-BMI), body surface area (BSA), thyroid volume, free thyroxine (fT4) and thyroid stimulating hormone (TSH) levels. Results. The mean TSH and fT4 levels did not show a significant difference between obese and normal-weight children (p>0.05). The mean thyroid volume was higher in obese children (6.46±5.84 and 4.64±1.44, respectively; p=0.043). fT4 correlated negatively with Z-BMI in both normal-weight and obese children (r=-0.285, p=0.004 and r=-0.289, p=0.004, respectively). Thyroid volume, on the other hand, correlated positively with Z-BMI, again in both normal-weight and obese children (r=0.657, p<0.001 and r=0.444, p<0.001, respectively). Similar associations were found for BSA. Conclusions. Thyroid volume correlated positively and fT4 correlated negatively with Z-BMI and BSA, in both obese and normal-weight school-age children, whereas TSH appears to be independent of these parameters.

Objectives. The present paper aims to review important contemporary information about VTE risk in endogenous and exogenous CS, as a substantial discrepancy exists between the results of a recent meta-analysis confirming the increased risk for VTE and the absence of CS in VTE guidelines. Methods. An extensive search of relevant databases (e.g. PubMed, Google Scholar, and Scopus) was performed in order to establish the interconnectedness of the following terms: Cushing’s syndrome, venous thromboembolism, deep vein thrombosis, pulmonary embolism. Results. The analysis demonstrated that patients with CS have about ten times the risk for VTE, particularly during the first year following the diagnosis of CS. Oral glucocorticoid users (with iatrogenic CS) have a 3-fold increase in risk of VTE in comparison with non-users. The most recent 2019 meta-analysis encompassed 7142 patients with endogenous CS (including Cushing’s disease) undergoing transsphenoidal surgery or adrenalectomy, and their risk of unprovoked VTE was almost 18 times higher in comparison with a healthy population. Conclusion. Over the past 50 years considerable evidence of increased VTE risk in CS has been accumulated. It pertains to both endogenous and exogenous type of CS and has been confirmed in the vast majority, if not all the available studies, including meta-analyses. Nevertheless, official CS guidelines make no mention of CS as a VTE risk factor, even though it is important that not only physicians who treat CS, but also physicians who manage patients with suspected VTE be aware of increased VTE risk.

Diabetes mellitus is a complex disorder of the energy metabolism of the human body. In the last WHO/ADA classification, the main forms of this disease are Type 1 (T1DM) and Type 2 (T2DM) diabetes mellitus. According to the same classification, the pathogenesis of T2DM is considered to include a progressive insulin secretory defect on the background of insulin resistance. Recently, controversies surround the concept of peripheral insulin\r\nresistance emerging in the 70's as an attempt to explain the differences from the T1DM phenotype whose autoimmune nature was as that time revealed. The insulin resistance\r\nhypothesis was based on the supposition that high plasma insulin levels are the result of a primary molecular defect against which the normal beta cells will react with an increased insulin secretion. This hypothesis has been\r\nused to explain both the pathogenesis of T2DM and the metabolic syndrome, named also for a short period of time "the insulin resistance syndrome". We will try to argue\r\nthat what it is attributed to peripheral insulin\r\nresistance belongs in fact to obesity. Special emphasis is put on the role of the adipocytes, including the secretion of different adipokines with the secondary lipotoxicity, oxidative stress and pro-inflammatory reaction, explaining the complex relationship between obesity and diabetes.

Background. There are many systemic illnesses that constitute risk factors for cerebral vein thrombosis (CVT).The association between cerebral venous sinus thrombosis and polycystic ovary syndrome (PCOS) has been rarely reported in the literature. This report\r\ndescribes a case of cerebral venous sinus thrombosis following intake of contraceptive pill (cyproterone acetate 2mg + etinil-estradiol 35 micrograms), for dysfunctional uterine bleeding secondary polycystic ovary syndrome in young women.\r\nCase report. We reported a 22-year-old women presented with severe headache associated with vomiting sudden onset; she had been taking contraceptive pills for the previous ten days. CVT was diagnosed with CT scan, MRI and MR venography. Laboratory investigations showed no evidence of inherited thrombophilia. The patient was treated with classic heparine, followed by acenocumarol with good clinical outcome.\r\nConclusions. This case illustrates that patients with polycystic ovary syndrome may develop thrombosis, if the patient is treated with combined contraceptives, even for short period of time. The role of PCOS as independent prothrombotic factor and the risk associated with oral contraceptive as first line treatement in PCOS need to be further investigated.

Background. The recurrent paralysis is the most important complication after total thyroidectomy. Vocal dysfunction can have multiple causes. Based on strict clinical criteria, the follow-up of patients who underwent a thyroidectomy may lead to wrong conclusions concerning possible recurrent nerve injury. Purpose. The aim of this study was to evaluate recurrential complications after total thyroidectomy by an ENT endoscopic examination. Method. We prospectively analyzed 100 cases of thyroid operations with a total number of 190 recurrent laryngeal nerve with lesional risk. Fourteen patients were operated for malignant disease. The patients were divided into two groups: group A (patients with high risk of recurrential injury) and group B (patients with low risk of recurrential injury). The operations were performed by one surgical team. The surgical interventions were followed in the 2nd postoperative day by an ENT endoscopic examination in order to assess vocal cords mobility. In patients with voice changes, ENT examination was repeated as many times was needed. At the same time a clinical examination of the quality of phonation was carried out. Results. From the total number of 100 patients examined with 190 nerves at risk, there were 7 patients with recurrent temporary paralyses (3.7%). After 6 months postoperative, there was a single patient with recurrent paralysis (0.5% ). Regarding permanent recurrent paralysis, there was no patient with paresis after one postoperative year (0%). There was no significant difference regarding the recurrent paralysis between patients with high or low risk of recurrential injury. Conclusions. The damage function of the recurrent nerve is recovered in 30 days in most cases and almost 100% in six months. Belonging to a low or high risk group is not associated with the development of motility disorders. The simple following of the clinical manifestations can lead to erroneous conclusions.

Objectives. Turner Syndrome (TS) is associated with a high risk of cardiac anomalies and cardiovascular disease. We aimed to evaluate patients with TS (n=33) for cardiac and aortic pathology using thorax magnetic resonance angiography (MRA). Subjects and methods. Clinical findings, karyotypes, echocardiogram (ECHO) findings and thorax MRA results were evaluated. Aortic dimensions were measured and standard Z scores of aortic diameters along with aortic size index (ASI) were calculated. Results. Mean age of the patients was 13.7±3.4 years. MRA revealed cardiovascular pathology in 10 patients (30%). CoA (n=4), aberrant right subclavian artery (n=3), dilatation of the ascending aorta (n=1), tortuosity of the descending aorta (n=1) and fusiform dilatation of the left subclavian artery (n=1) were found. Two of the four patients with CoA found on MRA were detected with ECHO. Mean diameter of the sinotubular junction was found to be elevated [mean±SD: 2.4±1.5]. Z scores for the diameters of the isthmus, ascending aorta and descending aorta were in normal ranges. 45,X patients were found to have significantly higher ASI values than non 45,X patients (p=0.036). Conclusion. Our findings indicate that patients with TS should be evaluated with MR imaging studies in addition to ECHO to reveal additional subtle cardiac and vascular anomalies. CoA which is very distally located or which has mild nature may not be seen by ECHO. The increase in ASI observed in 45,X patients may herald the development of life-threatening complications. Therefore, frequent followup is warranted in these patients.
