This guideline has been produced as the official statement of the European Thyroid Association guideline committee. Subclinical hypothyroidism (SCH) in pregnancy is defined as a thyroid-stimulating hormone (TSH) level above the pregnancy-related reference range with a normal serum thyroxine concentration. Isolated hypothyroxinaemia (defined as a thyroxine level below the 2.5th centile of the pregnancy-related reference range with a normal TSH level) is also recognized in pregnancy. In the majority of SCH the cause is autoimmune thyroiditis but may also be due to iodine deficiency. The cause of isolated hypothyroxinaemia is usually not apparent, but iodine deficiency may be a factor. SCH and isolated hypothyroxinaemia are both associated with adverse obstetric outcomes. Levothyroxine therapy may ameliorate some of these with SCH but not in isolated hypothyroxinaemia. SCH and isolated hypothyroxinaemia are both associated with neuro-intellectual impairment of the child, but there is no evidence that maternal levothyroxine therapy improves this outcome. Targeted antenatal screening for thyroid function will miss a substantial percentage of women with thyroid dysfunction. In children SCH (serum TSH concentration >5.5-10 mU/l) normalizes in >70% and persists in the majority of the remaining patients over the subsequent 5 years, but rarely worsens. There is a lack of studies examining the impact of SCH on the neuropsychological development of children under the age of 3 years. In older children, the evidence for an association between SCH and impaired neuropsychological development is inconsistent. Good quality studies examining the effect of treatment of SCH in children are lacking.

Background and aimsIntraoperative parathyroid hormone assay (IOPTH) has been used during minimally invasive parathyroidectomy (MIP) to predict operative success. However, the applied criteria are not equivalent in detection of multiglandular disease (MGD) and predicting cure. The purpose of this study was to evaluate the most commonly applied criteria of IOPTH in patients undergoing MIP in a tertiary referral center.Materials and methodsA retrospective review of 260 patients with sporadic primary hyperparathyroidism and concordant results of sestamibi scanning and ultrasound of the neck undergoing MIP (135 video-assisted and 125 open) between Dec 2002 and May 2008, with a 6-month postoperative follow-up of intact parathyroid hormone and serum calcium levels, was performed. The main outcome measures included evaluation of predictive values of Halle, Miami, Rome, and Vienna IOPTH interpretation criteria.ResultsThe following overall accuracy, sensitivity, specificity, positive predictive value, and negative predictive values were found, respectively: 65%, 62.9%, 100%, 100%, and 14.2% for Halle criterion; 97.3%, 97.6%, 93.3%, 99.6%, and 70% for Miami criterion; 83.8%, 82,9%, 100%, 100%, and 26.3% for Rome criterion; and 92.3%, 92.2%, 93.3%, 99.6%, and 60.9% for Vienna criterion.ConclusionsMiami criterion followed by Vienna criterion was found to be the best balanced among other criteria, with the highest accuracy in intraoperative prediction of cure. However, Rome criterion followed by Halle criterion was found to be the most useful in intraoperative detection of MGD. Nevertheless, their application in patients qualified for MIP with concordant results of sestamibi scanning and ultrasound of the neck would result in a significantly higher number of negative conversions to bilateral neck explorations and only a marginal improvement in the success rate of primary operations.

Objective 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.

UNLABELLED The recurrent laryngeal nerve (RLN) is particularly prone to injury during thyroidectomy in case of extralaryngeal bifurcation being present in approximately one-third of patients near the inferior thyroid artery or ligament of Berry. Meticulous surgical dissection in this area may be additionally facilitated by the use of intraoperative neuromonitoring (IONM) to assure safe and complete removal of thyroid tissue. The aim of the study was to verify the hypothesis that meticulous surgical technique of tissue dissection in the area of the posterior surface of the thyroid capsule and adjacent RLN may be additionally facilitated by intraoperative neuromonitoring (IONM), and may contribute to increasing the safety and radicalness of total thyroidectomy in patients with well-differentiated thyroid cancer. MATERIAL AND METHODS The outcomes of total thyroidectomy with level VI lymph node clearance for well-differentiated thyroid cancer (WDTC; pT1-3, N0-1, Mx) were retrospectively compared between 151 patients undergoing surgery with IONM (01/2005-06/2009) and 151 patients undergoing surgery without IONM (2003-2004). RLN morbidity (calculated for nerves at risk) was assessed by videolaryngoscopy or indirect laryngoscopy (mandatory before and after surgery and at 12-month follow-up). The anatomical course of the extralaryngeal segment of RLNs were analyzed in detail in each operation. Thyroid iodine uptake (131I) was measured during endogenous TSH stimulation test a week before radioiodine therapy. RESULTS Among patients operated with vs. without IONM, the early RLN injury rate was 3% vs. 6.7% (p=0.02), including 2% vs. 5% (p=0.04) of temporary nerve lesions, and 1% vs. 1.7% of permanent nerve events (p=0.31), respectively. Extralaryngeal RLN bifurcation was identified in 42 (27.8%) vs. 25 (16.6%) of patients operated with vs. without IONM, respectively (p=0.001). Mean I-131 uptake following total thyroidectomy with vs. without IONM was 0.67 ± 0.39% vs. 1.59 ± 0.69% (p<0.001). 131I uptake lower than 1% was found in 106 (70.2%) vs. 38 (25.2%) patients operated with vs. without IONM, respectively (p<0.001). CONCLUSIONS Most patients with WDTC who undergo total thyroidectomy have a small amount of residual thyroid tissue. The use of IONM may improve the outcomes of surgery among these patients by both increasing the completeness of total thyroidectomy and significantly reducing the prevalence of temporary RLN injury. The possible mechanism of this improvement is the aid in dissection at the level of the Berrys ligament offered by IONM which enhances the surgeons ability to identify a branched RLN, and allows for reduction of traction injury and neuropraxia of the anterior branch of bifid nerves.

OBJECTIVE To assess for the presence of gastric dysmotility in familial and sporadic Parkinson disease (PD). METHODS 10 subjects with familial Parkinson disease (fPD), 35 subjects with sporadic Parkinson disease (sPD), and 15 controls, all from academic tertiary care movement disorders centers, were studied. fPD was defined as the presence of at least 2 affected individuals within 2-3 consecutive generations in a family. Molecular genetic analysis has not revealed, thus far, any known genomic abnormality in these families. Gastric emptying was assessed by dynamic abdominal scintigraphy over 92 min following ingestion of a solid meal containing 99mTc-labeled colloid of 40 MBq activity. The main outcome measures were gastric emptying half-time and radiotracer activity over the gastric area at 46 and at 92 min. RESULTS Gastric emptying time was delayed in 60% of subjects with PD. In comparison to mean t(1/2) of 38 +/- 7 min in controls, mean t(1/2) was 58 +/- 25 min in fPD (p = 0.02) and 46 +/- 25 min in sPD (p = 0.10). Both fPD and sPD groups included subjects with delayed gastric emptying at an early stage of disease. CONCLUSIONS Patients with fPD showed significantly delayed gastric emptying in comparison to normal age-matched individuals. Further studies of gastrointestinal dysfunction in PD, particularly fPD, are warranted.

Background and aimsThe purpose of this study was to determine the utility of bilateral internal jugular venous sampling with rapid parathyroid hormone assay (BIJV–IOPTH) in comparison to endocrine surgeon-performed ultrasonography of the neck as an alternative localizing modality in guiding patients with primary hyperparathyroidism (pHPT) and negative sestamibi scans for minimally invasive parathyroidectomy (MIP).Patients and methodsSeventy eight consenting patients with a negative subtraction sestamibi scan planned for parathyroidectomy underwent additional ultrasound parathyroid imaging and were randomized to undergo surgery without vs. with additional BIJV–IOPTH; n = 39 in each group. The patients with a positive alternative imaging test were qualified for video-assisted MIP, whereas the others underwent open neck explorations. The primary outcome measure was the number of patients with true-positive results of alternative imaging tests.ResultsOf the 78 patients, 50 (64%) had a single adenoma, eight (10.3%) had double adenomas, and 20 (25.7%) demonstrated four-gland hyperplasia. Ultrasonography alone vs. combined with BIJV–IOPTH was true positive in detecting a solitary parathyroid adenoma in 8/24 (33.3%) vs. 17/26 (65.4%) patients, respectively (p = 0.023). Curative video-assisted MIP was successfully performed in all the patients with true-positive results. The remaining individuals were cured by more extensive open neck explorations (unilateral—4/39 vs. 4/39, respectively; p = 1.0 or bilateral—27/39 vs. 18/39, respectively; p = 0.039).ConclusionsMost patients with pHPT and a negative subtraction sestamibi scan (64%) have a single adenoma. BIJV–IOPTH as an addition to a surgeon-performed ultrasound of the neck allows for more accurate guiding for MIP in patients with a solitary parathyroid adenoma and negative subtraction sestamibi scans.

PURPOSE PRRT is a known tool in the management of patients with disseminated and inoperable NETs. The aim of study was to assess the effectiveness of the repeated cycles of PRRT in patients with disseminated and inoperable NETs. MATERIAL AND METHODS Eighty nine patients were included in the PRRT. Among them 16 patients (18%) were qualified for a repeated PRRT cycle due to progression of the disease. In one of the patients qualified for the repeated cycle, PRRT was used as neoadjuvant therapy. The results and side-effects of the repeated cycles of PRRT were analyzed. RESULTS Disease stabilization was observed in 10 patients 6 months after the repeated PRRT cycle and in 5 patients after 12 and 18 months. Ten of the patients who had received repeated PRRT cycles died. In the case of neoadjuvant therapy, further reduction of the tumor size was observed, enabling qualification for surgery. Clinically significant reduction in the mean values of morphological parameters was not observed. Only after 12 and 18 months the mean values of creatinine levels were higher than the normal range (only in 2 patients). CONCLUSIONS The repeated cycles of PRRT did not cause a clinically significant increase of the toxicity of PRRT. The changes in kidney and blood morphology parameters were transient. The repeated cycles of PRRT enabled stabilization of the disease.

Aim. The aim of the study was to analyze whether female sex hormones and other factors connected with the female sex could increase the risk of differentiated thyroid cancer (DTC). Material and methods. Ninety-nine patients with a mean age±SD of 40.5±5.9 years with DTC and 51 healthy women with a mean age of 36.52±8.3 years were examined. Gynecological and obstetric histories were taken and serum estradiol and progesterone levels were analyzed in all women. Results. Patients with DTC had more frequent menstrual cycle disturbances, used hormone-containing medicines more frequently, were mulitiparous more frequently, had spontaneous miscarriages more frequently, and their duration of lactation was significantly shorter than in controls. The mean serum estradiol level±SD in women with DTC was significantly higher than in the controls, in the follicular phase 193.74±66.31 vs. 157.63±42.88 pmol/l and in the luteal phase 519±176.9 vs. 369±71.49 pmol/l. The mean serum progesterone level±SD was higher in the controls than in patients with DTC, in the follicular phase: 2.11±0.70 vs. 1.38±0.56 nmol/l and in the luteal phase 20.95±17.46 vs. 17.31±12.28 nmol/l. Conclusions. The results of these studies imply that estrogens may at least modify the proliferation of thyroid cancer cells. The sex hormones probably intensify the actions of other carcinogens as well.

We present revised Polish guidelines regarding the management of patients harbouring neuroendocrine neoplasms (NENs) of the small intestine and appendix. The small intestine, especially the ileum, is the most common origin of these neoplasms. Most of them are well differentiated with slow growth. Rarely, they are less differentiated, growing fast with a poor prognosis. Since symptoms can be atypical, the diagnosis is often accidental. Typical symptoms of carcinoid syndrome occur in less than 10% of patients. The most useful laboratory marker is chromogranin A; 5-hydroxyindoleacetic acid is helpful in the monitoring of carcinoid syndrome. Ultrasound, computed tomography, magnetic resonance imaging, colonoscopy, video capsule endoscopy, balloon enteroscopy and somatostatin receptors scintigraphy are used in the visualisation. A histological report is crucial for the proper diagnostics and therapy of NENs, and it has been extensively described. The treatment of choice is surgery, either radical or palliative. Somatostatin analogues are crucial in the pharmacological treatment of the hormonally active and non-active small intestine NENs and NENs of the appendix. Radioisotope therapy is possible in patients with a good expression of somatostatin receptors. Chemotherapy is not effective in general. Everolimus therapy can be applied in patients with generalised NENs of the small intestine in progression and where there has been a failure or an inability to use other treatment options. Finally, we make recommendations regarding the monitoring of patients with NENs of the small intestine and appendix.
