    ABSTRACT: This study evaluated the relationship between selected acromegaly complications such as IGF-1 serum concentrations at diagnosis as well as of controlled and uncontrolled disease. A total of 113 acromegaly patients were enrolled to the study and the duration of active and uncontrolled disease was evaluated as a crucial cause of selected complications. Goiter, diabetes, hypercholesterolemia, hypertriglycerydemia, hypertension and ischemic heart disease were diagnosed in 85(75.2 %), 23(20.3 %), 48(51.0 %), 15(13.3 %), 65(57.5 %) and 18(15.9%) patients, respectively. Prevalence of goiter and diabetes was significantly related to the duration of uncontrolled acromegaly (p<0.01) as well as to the prevalence of hypertension and ischaemic heart disease (p0.05). After three years, there was a significant risk of an acromegaly patient being diagnosed at least with one of the above mentioned diseases (p<0.05) and such risk became more significant after four years (p0.05) related to the prevalence of the already mentioned complications. The treatment of acromegaly patients should be geared towards fulfilling all criteria for controlled disease, thereby alleviating potential complications and decreasing mortality.

    ABSTRACT: Most of the Polish territory has been classified as an iodine-deficient and endemic goiter area according to the International Council for Control of Iodine Deficiency (ICCIDD) criteria. In 1997 the obligatory model of iodine prophylaxis was implemented. Our investigations were aimed at the effectiveness of iodine prophylaxis in Poland. We assessed urinary iodine excretion and goiter prevalence in 5663 children aged 6-12 yr. The population of children from the same 27 schools was investigated from 1992 to 1994 (1406 girls and 1244 boys) and from 1999 to 2005 (1563 girls and 1450 boys) using identical laboratory and ultrasound methods. We found significant increase in iodine urinary concentration (median 52 microg/l vs 93 microg/l, p<0.001) with accompanying drop in goiter prevalence (29.6% vs 5.2%, p<0.001) after implementation of iodine prophylaxis. Iodine excretion distribution changed significantly after 1997 with an increase in the percentage of children with iodine urinary concentration above 100 microg/l from 10.8% to 45.4%, respectively. A significantly higher iodine urinary concentration was observed in lowlands compared to uplands both before and after implementation of iodine prophylaxis (median, 50 microg/l vs 57 microg/l and 86 microg/l vs 114 microg/l, respectively, p<0.001). The goiter prevalence did not differ between girls and boys from 1992 to 1994 (28.8% vs 30.5%, p=0.35) and 1999 to 2005 (5.5% vs 4.9%, p=0.45). Implementation of the new model of iodine prophylaxis in Poland in 1997 has led to significant increase in iodine urinary concentration and decrease in goiter prevalence among Polish schoolchildren. In the youngest group of children (6-8 yr olds), prevalence of goiter decreased to 3.2%--i.e. below endemic levels.

    ABSTRACT: Intraoperative parathyroid hormone assay (IOPTH) is often used during minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism (pHPT). However, several investigators have reported conflicting outcomes, throwing doubt on the real influence of this adjunct on surgical decision-making. The aim of this study was to determine the impact of routine use of IOPTH on the success rate of MIP as the primary outcome, and whether it value-added to surgical decision-making during the operations at our institution. The results of MIP were determined on postoperative follow-up in 177 consecutive patients with pHPT and compared with the results of preoperative imaging, findings at surgery and the value-added accuracy of IOPTH in surgical decisions. All 177 patients had biochemically documented pHPT and all were referred for first-time surgery. Group 1 patients (n = 62) underwent a unilateral neck exploration (UNE) without IOPTH, and group 2 patients (n = 115) underwent MIP (either video-assisted or open) with IOPTH. The primary outcome was the cure rate, whereas the secondary outcome was the value-adding of IOPTH to surgical decision-making during MIP. Of the group 1 vs. 2 patients, 57/62 (91.9%) vs. 114/115 (99.1%) were cured (P = 0.01). Five (8.1%) of the group 1 patients were hypercalcaemic postoperatively, owing to an additional, overlooked, hyperfunctioning parathyroid gland, whereas among the 115 group 2 patients, 104 (90.4%) underwent resection of a single parathyroid adenoma, met the Miami criterion, and were cured. The remaining 11 (9.6%) patients did not have an adequate reduction in parathyroid hormone levels and underwent further neck exploration, with resection of additional hyperfunctioning parathyroids in nine of them. One group 2 patient was not cured. However, a decrease of less than 50% of intraoperative parathyroid hormone (iPTH) assay correctly identified the risk of persistent disease in that patient. Another patient in group 2 had a false-negative IOPTH result. The value-added accuracy of IOPTH (correct assay-based surgeon's decision of further neck exploration) was demonstrated in 3 of 78 group 2 patients with concordant results of both imaging studies vs. 7 of 37 group 2 patients with only one positive imaging study, or 3.8 vs. 18.9% of patients (P = 0.007). Routine use of IOPTH significantly improves cure rates of MIP in comparison to open image-guided UNE without IOPTH. It is a valuable adjunct in surgical decision-making, allowing for intraoperative recognition and resection of additional hyperfunctioning parathyroid tissue missed by preoperative imaging studies. IOPTH offers substantial value-adding to surgical decision-making, particularly in patients with only one positive imaging study result, and significantly improves the success rate of MIP in these patients. However, in patients with concordant results of two imaging studies, the assay offers significantly lower value-adding to surgical decisions, as a vast majority of patients are cured after removal of a two-image-indexed parathyroid lesion. Despite this, we strongly advocate routine use of IOPTH in all patients undergoing MIP, as this adjunct offers maximum safety for the patient and confidence for the surgeon.

    ABSTRACT: To determine the sensitivity and positive predictive value (PPV) of subtraction scintigraphy (SS) vs. ultrasonography (US) of the neck combined with rapid intact parathyroid hormone (iPTH) assay in US-guided fine-needle parathyroid aspirates in preoperative localization of parathyroid adenomas and in directing surgical approach. The results of SS for localization of parathyroid adenoma were determined in 121 patients with primary hyperparathyroidism (pHPT) and compared with findings at surgery and with the results of US alone (in patients without nodular goitre) and US in combination with the iPTH assay in US-guided fine-needle aspirates (FNAs) of suspicious parathyroid lesions (in patients with concomitant nodular goitre). All 121 patients had biochemically documented pHPT; all were referred for first-time surgery. SS was performed with 99mTc-sestamibi and 99mTc-pertechnetate. High-resolution US of the neck was performed by a single endocrine surgeon and combined with US-guided FNAs of suspicious parathyroid lesions in all patients with nodular goitre (n = 43). The sensitivity and PPV of SS were significantly higher in patients without vs. with goitre (89.3% and 95.7%vs. 74.3% and 76.5%, respectively; P < 0.001). The sensitivity and PPV of US were significantly higher in patients without vs. with goitre (96% and 97.3%vs. 67.7% and 71.9%, respectively; P < 0.001). The iPTH assay of US-guided FNAs of suspicious parathyroid lesions in patients with nodular goitre significantly improved both the sensitivity and PPV of US imaging (90.7% and 100%, respectively), allowing for an accurate choice of surgical approach in 118 (97.5%) of 121 patients. SS was more accurate than US alone in detection of ectopic parathyroid adenomas. However, US alone was characterized by a higher sensitivity in detection of small parathyroid adenomas (< 500 mg) at typical sites (P < 0.01). Both the sensitivity and PPV of SS and US alone are comparable, with significantly less accurate results obtained in patients with goitre. In cases of equivocal results of US and/or in patients with concomitant goitre, an iPTH assay in US-guided FNAs of suspicious parathyroid lesions may be used to establish the nature of the mass, distinguish between parathyroid and nonparathyroid tissue (goitre, lymph nodes) and improve the accuracy of US parathyroid imaging, allowing for successful directing of surgical approach in a majority of patients.
