Review Meta Analysis
A systematic review and meta-analysis of prophylactic central neck dissection on short-term locoregional recurrence in papillary thyroid carcinoma after total thyroidectomy.
Prophylactic central neck dissection (pCND) at the time of total thyroidectomy (TT) remains controversial in clinically node-negative (cN0) papillary thyroid carcinoma (PTC). Despite occult central lymph node metastases being common, it is unclear if removing these metastases initially would reduce future locoregional recurrence (LRR). This systematic review and meta-analysis aimed at comparing the short-term LRR between patients who underwent TT with pCND and those who underwent TT alone. ⋯ Group A was more likely to have postoperative RAI ablation, temporary hypocalcemia, and overall morbidity than group B. Temporary hypocalcemia was the major surgical morbidity in pCND and, when excluded, the overall morbidity appeared similar between the two groups. Although our meta-analysis would suggest that those who undergo TT + pCND may have a 35% reduction in risk of LRR than those who undergo TT alone in the short term (< 5 years), it remains unclear how much of this risk reduction is related to increased use of RAI ablation and potential selection bias in some of the studies examined.

Review Meta Analysis
Which hemostatic device in thyroid surgery? A network meta-analysis of surgical technologies.
Energy-based hemostatic devices are increasingly being used in thyroid surgery. However, there are several limitations with regard to the existing evidence and a paucity of guidelines on the subject. The goal of this review is to employ the novel evidence synthesis technique of a network meta-analysis to assess the comparative effectiveness of surgical technologies in thyroid surgery and contribute to enhanced governance in the field of thyroid surgery. ⋯ The comparative effectiveness of ultrasonic coagulation in thyroid surgery outcomes seems superior to other techniques with the exception of recurrent laryngeal nerve injury. This network meta-analysis, one of a handful in a surgical field, offers preliminary and robust evidence to guide clinical decisions and policy makers to adopt safer thyroid operations.

Review Case Reports
Hyperthyroidism caused by an ectopic thyrotropin-secreting tumor of the nasopharynx: a case report and review of the literature.
Ectopic thyrotropin (TSH)-secreting tumors are extremely rare. To our knowledge, only three cases have previously been reported so far, but the tumors were not studied ultrastructurally and in vitro. We present a case that was extensively examined to gain deeper insights in terms of the histopathological features and hormonal secretion profile of the tumor. ⋯ Ectopic TSH-secreting tumors are extremely rare. In terms of hormone secretion profile, histological characteristics, and response to octreotide, they are similar to pituitary TSH-secreting adenomas, suggesting that they are of identical cell origin.

Quality of life is an important issue in endocrine tumors because of the high prevalence of benign tumors and the indolent course of most malignant tumors. ⋯ FNAC-related pain is frequent and correlates with the number of nodules biopsied, age under 25 years, female sex, and anxiety.
