Abstract
Usual treatment for patients with aldosterone-producing adrenal adenoma is adrenalectomy, whereas adrenal hyperplasia is generally treated medically. Selective adrenal venous sampling (AVS) has been adopted to differentiate between adenoma and hyperplasia. A previous ratio used in our institution for the diagnosis of adenoma proved to be too low. As a result, a disproportionate number of patients with a preoperative diagnosis of adenoma were operated and subsequently found to have hyperplasia. This prospective study evaluated the long-term outcomes of unilateral laparoscopic adrenalectomy in the setting of lateralizing aldosterone hypersecretion caused by adrenal hyperplasia. Twelve patients with unilateral excess aldosterone production due to hyperplasia underwent dominant side adrenalectomy. Long-term follow-up (mean 12 years) of these patients showed that blood pressure decreased from a mean of 163.4 ± 17.5 Dominant side adrenalectomy in patients with primary aldosteronism (PA) due to hyperplasia results in long-term clinical improvement. This procedure should be considered in selected patients with lateralization confirmed by venous sampling. Paran H, Elad G, Benchetrit S, Griton I, Haas I, Yaslowitz O, Shmulevsky P.

Abstract
Thyrotoxicosis due to Graves’ disease (GD) and destructive thyroiditis (DT) needs differentiation, as management strategy differs. Factors that help in diagnosis are biochemical and nuclear imaging. Utility of high-resolution ultrasonography (HRUSG) and color Doppler (CD) in differentiation is not widely practiced. We undertook the prospective study in the Department of Endocrine Surgery at a tertiary care center among South Indian population in 1 year as a cost-effective model Out of 120 newly diagnosed thyrotoxicosis patients, 54 were GD (group I) and 66 were DT (group II) patients. Totally, 55 euthyroid patients served as controls. Parameters analyzed were demography, free thyroid function test (TFT) anti-thyroid-stimulating hormone receptor antibody (TSHrAB), antithyroid peroxidase antibody (ATPO), anti-thyroglobulin antibody (ATG), and Tc-99m thyroid scintigraphy. Parameters analyzed using HRUSG and CD were peak systolic velocity (PSV), end-diastolic volume (EDV), pulsatility index (PI), resistive index (RI) of bilateral superior thyroid artery (STA) and inferior thyroid artery (ITA). Both groups were age and sex matched. The TFT, ATPO, and ATG were comparable between both groups (p = 0.609). The TSHrAB (IU/mL) was significantly higher in group I (36.11 ± 0.82) than group II (1.23 ± 0.24) (p < 0.001). Mean thyroid volume (mL) was higher in group I (28.9 ± 14.9) than group II (26.2 ± 8.81) (p = 0.022). Mean PSV-STA (cm/s) was statistically higher in group I (54.09 ± 4.67) than group II (28.92 ± 4.39) (p ≤ 0.001). Mean PSV-ITA (cm/s) was higher in group I (32.11 ± 2.45) than group II (25.23 ± 3.45) (p = 0.006). Other parameters measured in both arteries like mean EDV (cm/s), mean RI, and mean PI were comparable between both groups. The HRUSG with CD evaluation of PSV STA and ITA is a cost-effective alternative to TSHrAB and thyroid scintigraphy in differentiating GD from DT patients. Additionally, we observed that PSV in STA was higher than in ITA in patients with GD. To conclude, HRUSG and CD are simple, cost-effective, and widely available tools in the differentiation of GD from DT. Sundarram KST, Sadacharan D, Ravikumar K, Kalpana S, Suresh RV.

Abstract
Recognizing the paucity of data regarding the incidence of cardiovascular abnormalities in severe primary hyperparathyroidism (PHPT), a prospective study was done for left ventricular (LV) systolic and diastolic function by echocardiography in patients with hyperparathyroidism (HPT) before surgery. A total of 18 consecutive patients with HPT and an equal number of age- and sex-matched controls were studied by two-dimensional and Doppler echocardiography. Patients with HPT had higher systolic and diastolic blood pressures (BPs). Despite severe bone disease, nephropathy, and vitamin D deficiency, none had metastatic calcification in myocardium. There was no significant increase in LV systolic dimensions and volume, but decreased ejection fraction (EF) and significant diastolic dysfunction were observed. Despite an asymptomatic cardiac status, there were decreased EF and significant diastolic dysfunction. The HPT patients despite having severe disease, did not have metastatic calcification.

Abstract
We have realized that recent rise in incidence of thyroid malignancy is partly because of incidental findings of cancer after resection for benign goiters. Therefore, we aim to reanalyze risk factors for thyroid malignancy in those patients who underwent primary thyroid surgery at Breast and Endocrine Surgical Unit, Department of Surgery, Hospital Raja Perempuan Zainab II, Kota Bharu, Kelantan, Malaysia. Retrospective review in our database found 699 patients who had undergone thyroid surgeries between June 2007 and December 2014. According to the final histopathological report of resected specimen, these patients, operated for goiter, were divided into two groups: Thyroid malignancy group and nonmalignancy group. Logistic regression analysis was used to estimate the risk of age, duration and weight of resected specimen for having thyroid malignancy. The mean value for age was 43.5 years [standard deviation (SD) = 14.0); duration of neck swelling was 5.9 months (SD = 6.7); and weight of resected specimen was 157 gm (SD = 161.0). Around 26.9% cases had thyroid malignancy (n = 188), about 77.13% cases had papillary thyroid carcinoma and 17.6% had follicular thyroid carcinoma. Age associates with risk for malignancy (p < 0.001), but duration of neck swelling (p = 0.513) and weight of resected specimen (p = 0.955) do not relate with this. With an increase of 1 year of age, the odds to have thyroid malignancy increase for 2%. This is equivalent with 14.4% increase in cancer for every 5-year increase in age. Our study has found that increasing age is the only associated factor for risk of thyroid malignancy. When managing elderly patients who has clinically benign goiter, differential diagnosis of thyroid cancer need be considered as well. Wong MW, Hadi IA, Musa KI.

Abstract
Surgery, by minimally invasive approach, has become the gold standard in the treatment of primary hyperparathyroidism. However, the preoperative and intraoperative examinations to be performed are still subject to debate. The frozen tissue examination of the parathyroidectomy specimen is often criticized, as it is deemed difficult and noninformative in case of multiglandular disease. The primary objective was to study the result of the frozen tissue examination and its benefit in the operative strategy in minimally invasive surgery. This is a single-centre retrospective descriptive study on patients who underwent surgery for primary hyperparathyroidism between January 2011 and September 2013 at Besançon A total of 157 patients were treated for hyperparathyroidism and 97 were enrolled in the study. The mean age was 62.3 ± 13.7 years, mean serum calcium was 2.81 ± 0.24 mmol/L and the mean parathyroid hormone (PTH) level was 175 ± 120 pg/mL. Around 53 patients (54.6%) had concordant scintigraphic and ultrasound examinations while 20 patients (20.6%) had an isolated contributory scintigraphic examination, 21 patients (21.6%) had an isolated contributory cervical ultrasound and 3 patients had discordant examinations. The sensitivity of the preoperative imaging in case of concordance was 84.9% for the location of the diseased gland, and 92.4% for its lateralization. The sensitivity to ultrasound alone and scintigraphy alone was 61.9% and 65% respectively. Nearly 23 false positive imaging results were found in which 11 were corrected during surgery by the surgeon based on the macroscopic appearance. The frozen tissue examination of the surgical specimen changed the surgical strategy in 12 cases (12.4%): Six results of normal parathyroid gland (50%), four results of thyroid tissue (33.3%), and two cases of hyperplastic gland (16.7%). The results of the frozen tissue examination thus led to 12 exploratory cervicotomies, which revealed three ipsilateral adenomas (25%), six contralateral adenomas, and one adenoma included in the thyroid lobe, and enabled the surgeon to perform two subtotal parathyroidectomies for parathyroid hyperplasia. The mean duration of the frozen tissue examination was 24.2 ± 8.6 minutes and the cure rate is 100% for the population treated by minimally invasive approach. In our experience, the frozen tissue examination enabled the surgeon to intraoperatively correct 12 erroneous imaging diagnoses, including two cases of parathyroid hyperplasia and thus to continue the exploration of other glands and immediately carry out the appropriate treatment. This is an interesting technique, but it is conditioned by the pathologist’s expertise. Furderer T, Bouviez N, Paquette B, Landecy G, Heyd B, Vienney G, Lakkis Z, Tauziede M.
