ACTA ENDOCRINOLOGICA (BUC)

Objective. To compare results of treatment of primary hyperparathyroidism (PHPT) in two teaching hospitals (eastern and western Europe) and to establish conclusions regarding quality of surgery for PHPT in Romania. Methods. We reviewed two prospectively collected databases of patients submitted to open minimally invasive parathyroidectomy (OMIP) for symptomatic PHPT in two centers from Romania and the United Kingdom (UK). We included patients with biochemically proven PHPT and positive pre-operative localization studies. We excluded patients with negative localization studies, suspected multiglandular disease, concomitant thyroid disorders and chronic renal failure. Results. 60 patients were included, 27 in group A (Romanian cohort) and 33 in group B (UK cohort). We noted significant differences between groups in pre-operative serum calcium and phosphorus levels (p<0.5). There were no differences between groups regarding the presence of symptoms; in group A we had significantly more patients with renal calculi history (p=0.02), digestive symptoms (p=0.006) and osteitis fibrosa cystica (p=0.01). Two patients from the UK group had lithium associated hyperparathyroidism and 2 patients had genetic disease. Intraoperative parathyroid hormone measurement (ioPTH) was available only for group B and frozen sections were selectively used in both groups. Both the adenoma size and weights were significantly higher in group A. The median operative time was significantly longer in Romanian group (p=0.001); in this group we noted the single conversion to traditional cervicotomy (3.7%) from all studied patients. In group A we noted two patients (7.4%) with failed parathyroidectomy and persistent PHPT; the cure rate was 92.5% for Romanian group and 97% for the UK group. Conclusions. OMIP can be performed safe with a high cure rate in “small” volume endocrine centres with results comparable to western experienced endocrine centres. Romanian patients presented with more severe PHPT with more frequent end-organ damage, due probably to late diagnosis.

Objective. We analyzed the correlation between glycemic variability and psychological problems such as depression, anxiety disorder, and low self-esteem in pregnant and non-pregnant (excluding gestational diabetes) patients with diabetes. Besides its originality, this study might contribute to better / earlier diagnosis of these psychological conditions, with a special interest in pregnant diabetic women. Better management and cost reduction of care could be a consequence. Methods. We compared diabetic pregnant and non-pregnant women from the perspective of the glycemic variability (for a period of 15 days prior inclusion in the study) and their results on the standardized questionnaires: Beck depression inventory, Hamilton anxiety scale – HRSA, Rosenberg self-esteem test. Results and Conclusions. A statistically significant correlation was identified in both groups between the glycemic oscillation and depression, anxiety, and low selfesteem. Diabetic pregnant women had a higher statistical significance for the correlation between the glycemic oscillation and depression, as well as between the glycemic oscillation and anxiety than non-pregnant diabetic patients. The present data justify further research. Our results could be developed into a preliminary intervention protocol, using the daily glycemic values measurements, collected by patients.

experience regarding the first 24 patients diagnosed with refractory secondary and/ or tertiary hyperparathyroidism (HPT) who underwent subtotal parathyroidectomy (sPTx) in our clinic between 2010 and 2012. Methods. Data were retrospectively retrieved from a prospectively maintained database. We included patients diagnosed with refractory secondary and/or tertiary HPT who underwent sPTx; we excluded patients who underwent total parathyroidectomy (tPTx) and patients followed-up for less than six months. Results. We analyzed 24 patients,16 women (66.7%) and 8 men (33.3%) who were evaluated in a prospective manner in a short (1-6 months)/ medium (6-18 months) term follow up. Preoperative intact parathyroid hormone level (iPTH) was characterized by a median of 2131 pg/ mL (range: 1141-10000); in the first month after surgery the median iPTH level was 28 pg/mL (range: 3-1263). We found a statistically significant difference (p<0.01: Student test) in calcium level between preoperative values and values in the first month after surgery. Postoperative serum phosphorus (nv: 2.7-4.5 mg/dL) normalized in 19 patients (79.16%) and serum alkaline phosphatase values decreased significantly in the interval 2-6 months postoperative versus preoperative levels (p-0.002). We tried to establish a correlation between preoperative alkaline phosphatase (Alk Phos) and postoperative calcium level in the first month postoperatively. The overall clinical response to sPtx was good and we did not encounter postoperative mortality in our series. Conclusion. We believe that subtotal parathyroidectomy is feasible, safe and effective for patients with refractory secondary and tertiary hyperparathyroidism.

Background. Postoperative hypocalcemia after thyroid surgery has a high prevalence ( 16-55% in different series). Incidental parathyroidectomy (IP) is a less discussed complication of thyroidectomy with consequences not properly defined. The aim of our study was to find incidence, risk factors and how to prevent IP. Methods. Extensive search of English literature publications via PubMed was performed and 73 papers from 1980 to 2017 were analysed using the GRADE system/classification, quality of evidence was classified as “strong” when the result is highly unlikely to change existing recommendation and “weak” when opposite. Results. Incidence of IP is 3.7-24.9%, while prevalence of permanent hypoparathyroidism is less frequent 6-12%. Direct relation between IP and hypoparathyroidism/ hypocalcemia remains controversial. Female patients, ectopic parathyroids, small thyroids, Graves’, malignancy, redo surgeries and total thyroidectomy favour IP. Routine visualization of parathyroids, new hemostatic devices, magnifying instruments and fluorescence can prevent incidental removal of parathyroids. Incidence of IP during videoassisted or robotic thyroidectomies was similar to open procedures. High volume, experienced and younger surgeons have lower complication rates (including hypoparathyroidism). Conclusions. Incidental parathyroidectomy is more frequent than we might have expected. It should be avoided and parathyroid glands should be kept in situ. Majority of studies are retrospective (low degree of evidence according to previous mentioned GRADE classification) and further meta-analysis or randomized control studies are welcome in order to define the impact of incidental removal of parathyroids on postoperative outcome.

Objective. We analyzed the possible correlation between glycemic variability and psychological disorders such as depression, anxiety disorder, and low self-esteem, in diabetic patients. These correlations are relevant, as they consume a large number of resources. Their better understanding can increase the effectiveness of incident reduction techniques and could provide better management and cost reduction of care. Methods. We compared the relationships between the glycemic variability (for a period of 10 days prior to completing the depression questionnaire) and the results of two standardized questionnaires: Hamilton anxiety scale - HRSA (group 1: 500 patients), Rosenberg self-esteem test (group 2: 490 patients) and Beck depression inventory (both groups). Results. A statistically significant correlation was identified between the glycemic oscillation and depression as well as both anxiety and low self-esteem. The present data justify further research. Our results could be developed into a preliminary intervention protocol, using the daily glycemic values measurements, collected by patients. In conclusion, psychometric tests could be an important instrument in the management of diabetic patients.

kidney disease (CKD), a growing public health issue, than in general population. The key issue in management of fragility fracture in CKD patients is determining whether fractures have occurred as a result of qualitative abnormalities (consequences of renal osteodystrophy or CKD-mineral and bone disorder), a reduced bone mineral density (osteoporosis) or a combination of both. In CKD patients bone histomorphometry is the gold standard for evaluating bone quality and strength, but the routine use of this method is not practical. Fracture risk can be assessed in this population by DEXA (Dual-Energy X-Ray Absorptiometry), but biochemical markers, like intact PTH and bone-specific alkaline phosphatase may be helpful. The new and emerging high resolution imaging tools need more studies for a correct evaluation of their utility in predicting fracture risk. Pharmacological therapies for fragility fracture based on current understanding of the metabolic disturbances in CKD will be reviewed. Antiresorptive and anabolic agents used in the treatment of osteoporosis are discussed with special focus on CKD population.
