ACTA ENDOCRINOLOGICA (BUC)

Endemic goiter occurred in different degrees throughout 2/3 of Romania, mainly in the Carpathian area. The prophylaxis of iodine deficiency disorders (IDD) using salt iodization was introduced in 1956 with potassium iodate, KIO3, 15-25 mg/1kg salt, but only in 23 districts. In 2002 a new legislation introduced the mandatory use of the iodized salt in a higher concentration in households of all 41 districts and also in the baking industry. The study aims to evaluate the effects of iodine legislation changes upon the urinary iodine excretion (UIC) in schoolchildren (study group A) and pregnant women (study group B). Urine samples were collected from 3737 schoolchildren aged 6-14 years of 14 districts and from 1283 pregnant women of 11 districts in the years 2004-2005. In two areas - Bistrita Nasaud and Bucharest - the number of schoolchildren was larger, i.e. 465 and 1617 respectively. UIC was determined in spot urine samples by Sandell Kolthoff?s method. The results show in schoolchildren an increase of the median UIC in 9 out of 14 districts up to 90 ? 61.1 ?g/L (range 12.5-300 ?g/L). Six of these districts are in the Carpathian area. However, in pregnant women in 2004, UIC still showed low levels of 55 ? 48.78 ?g/L (range 12.5-280 ?g/L) in all 11 studied districts and in Bucharest, close to the UIC obtained in the year 2001. In conclusion, this study revealed an increase of median values of UIC in schoolchildren after universal salt iodization program. The persistence of iodine deficiency in pregnant women in the studied districts is an emergency problem that has to be solved as soon as possible. This fact involves the necessity of a large monitoring program in the next years, in all districts in urban and rural areas and in all known pockets of endemia.

Cardiovascular disorders represented by congenital malformations, hypertension, aortic dilatation which can emerge in dissection or rupture and ischemic heart disease are common in Turner syndrome (TS) and life-threatening. Echocardiography and magnetic resonance imaging represent complementary diagnostic methods used to assess cardiovascular status. Unfortunately, normal reference ranges for cardiac and aortic measurements are established only in unselected TS patients, preventing a delineation between patients with and without cardiovascular pathology. We performed echocardiography in 15 patients with TS, aged 12-33 years (mean 21.8 years, standard deviation 6.37 years) without cardiovascular and renal malformations, hypertension or aortic dilatation and 30 normal controls; karyotype was 45,XO in 11 patients and 45,XO/46,XX in four patients. To minimize the influence of body size, ratios of aortic and cardiac chambers dimensions were calculated. As expected, we found smaller dimensions in TS versus controls but only the ascending aorta, left atrium and diastolic left ventricular diameters and the ratio diastolic / systolic left ventricular diameters reached statistical significance. Only aortic dimensions were entirely independent of age, height, weight and BMI with a 95% confidence interval of 14.28 – 25.32 (mean 19.8) mm for the aorta at the annulus and 95% CI 21.42 – 29.36 (mean 25.54) mm for the ascending aorta. The ratios ascending aorta/ systolic left ventricular diameter (95% confidence interval 0.54 – 1.34; mean 0.94), aorta at the annulus/systolic left ventricular diameter (95% CI 0.44 – 0.92; mean 0.68) and aorta at the annulus/ diastolic left ventricular diameter (95% CI 0.36 – 0.61; mean 0.49) are independent of age, height, weight and can also be reliable for detection of aortic dilatation.

We present the case of a 32 yeas old male, diagnosed 7 years ago with Graves disease, with numerous recidives which needed anti-thyroid medication, with poor response (hypo to hyper-thyroid status, with high variations of TSH and FT4) whom after a period of remission (8 months, no treatment) came in for a polymorphic symptomatology sugestive for hyperthyroidism. The hyperthyroid state was confirmed he had high TRAb (31 UI/ml vs. <1.75 UI/ml) - on his last check in the detection rate of TRAb was under 0.3 UI/ml. The thyroid ultrasound revels on the left lobe a small mass of 0.8/0.8 cm, with EU-TIRADS score of 4, that was newly diagnosed. Postoperative histopathology revealed papillary microcarcinoma developed on Hashitoxicosis- pT1aN0, of 1 mm in the middle of left thyroid lobe. The particularity of this case consists in a long evolution of Graves disease with numerous relapses, the appearance of a thyroid nodule after 7 years in which they identified a papillary microcacinoma associated with Hashimoto thyroiditis and also the postoperative recovery that was slowed by the parathyreoprive tetany.

Background. Adipokine secretion is influenced by various disease conditions. Purpose. We wanted to check the impact of rectal carcinoma (RC) on adipokine profile. Patients and methods. We evaluated serum leptin and adiponectin levels in 24 RC patients (12 males and 12 females) as well as in the same number of age, sex and weight-matched healthy controls. Results. Adipokines were oppositely correlated with body weight (BW) in controls and RC patients. Women had higher adipokine levels than men. Healthy controls had higher leptin (37.6.±7.8 vs. 7.9±2.6 ng/mL in women and 11.9±4.6 vs. 1.4±0.34 ng/mL in men, p=0.0016 and 0.043) and lower adiponectin levels (9.3±1.1 vs. 14.9±1.1 μg/mL in women and 7.9±0.9 vs. 11.1±0.9 μg/mL in men, p=0.012 and 0.017) than RC patients. Conclusion. Adipokine profiles of patients with RC differ from the healthy population, possibly reflecting an adaptation to the disease rather than a triggering factor. These differences may find clinical applications for the prognosis of disease evolution.
