Background: Management of thyroid diseases during pregnancy requires special considerations because maternal thyroid diseases can have adverse effects on both pregnancy and fetus. Universal screening for thyroid diseases in pregnant women is not currently supported by studies with high evidence whereas guidelines have been released for individuals at high risk, although controversies are still in debate. Iodine prophylaxis should be performed systematically to women during pregnancy.Materials and Methods: An electronic search of PubMed/Medline and EMBASE concerning thyroid diseases and pregnancy have been conducted over the past 20 years and summarized.Results: Data regarding prevention and treatment of thyroid diseases during pregnancy are reported from analysis of the literature.Conclusions: As thyroid dysfunction may cause profound impact on mother's and fetus's health, implementation by strict application of clinico-diagnostic flowchart and recommendations is of paramount importance when dealing with thyroid diseases during pregnant state.

Objective:We present a case of large, symptomatic lingual thyroid which was successfully and safely removed via a transoral approach, using the da Vinci robotic system, in an academic medical centre in Singapore.Case report:A 17-year-old female adolescent presented with a large lingual thyroid causing upper airway obstruction. She underwent robotic, minimally invasive, transoral resection using the da Vinci system. Post-operative recovery was uneventful; she was able to commence oral feeding almost immediately, and was discharged from hospital on the fourth post-operative day.Conclusion:It is surgically feasible and safe to undertake transoral robotic resection of a large lingual thyroid. This approach may allow faster recovery and shorter hospitalisation for patients. Surgical safety requires a full understanding of the intralingual neurovascular anatomy. [ABSTRACT FROM PUBLISHER]

Objective: To review the optimal use of sensitive assays for thyroid-stimulating hormone (TSH) by clinicians.Methods: The available literature pertinent to the clinical application of sensitive TSH testing was identified through a systematic MEDLINE search and reviewed. Selection of materials for inclusion was based on clinical validity of the data and relevance to the study question.Synopsis: Sensitive TSH assays have contributed greatly to our basic knowledge of thyroid physiology and are a powerful clinical tool in the diagnosis and treatment of thyroid disease. The clinical applicability of these assays, as is our understanding of their appropriate use, is rapidly expanding. Based upon the best evidence and current understanding of thyroid physiology, strategies are presented for appropriate use of sensitive TSH assays in healthy outpatients, in patients who are likely to have a disturbed hypothalmic-pituitary-thyroid axis, and in patients on levothyroxane therapy.Conclusions: Although many clinical questions regarding the use of sensitive TSH assays remain to be studied, it has emerged as a powerful tool for the diagnosis and management of thyroid disease. Optimal use of sensitive TSH assays requires an understanding of TSH physiology and measurement, coupled with appropriate application and interpretation in specific clinical settings.
