Thyroid resections represent one of the most common operations with 76,140 interventions in the year 2016 in Germany (source Destatis). These are predominantly benign thyroid gland diseases. Recommendations for the operative treatment of benign thyroid diseases were last published by the CAEK in 2010 as S2k guidelines (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e.V. [AWMF] 003/002) against the background of increasingly more radical resection procedures. Hemithyroidectomy and thyroidectomy are routinely performed for benign thyroid disease in practice. The operation-specific risks show a clear increase with the extent of the resection. Therefore, weighing-up of the risk-indications ratio between unilateral lobectomy or thyroidectomy necessitates an independent evaluation of the indications for both sides. This principle in particular has been used to update the guidelines. In addition, the previously published recommendations of the CAEK for correct execution and consequences of intraoperative neuromonitoring were included into the guidelines, which in particular serve the aim to avoid bilateral recurrent laryngeal nerve paralysis. Moreover, the recommendations for the treatment of postoperative complications, such as hypoparathyroidism and postoperative infections were revised. The updated guidelines therefore represent the current state of the science as well as the resulting surgical practice.
During cycle stimulation for in-vitro fertilisation (IVF) some patients develop hyperprolactinaemia. Since prolactin (PRL), being an aromatase inhibitor, can interfere with follicular fluid steroid metabolism, we examined the influence of high serum PRL levels on the endocrine response and fertilisation rate of oocytes. 33 consecutive patients stimulated by hMG/hCG for IVF were included in this study. Two groups of patients were established: Group 1 consisting of 18 patients with serum PRL levels less than or equal to 25 ng/ml, and group 2 containing 15 patients, who developed PRL levels greater than 25 ng/ml during cycle stimulation. The serum oestradiol (E2), progesterone (P) and PRL levels 3, 2 and 1 day before and at the day of follicle puncture were evaluated. The decrease of E2 levels at the day of oocyte retrieval was significantly steeper in group 1. The P levels 2 days before oocyte retrieval were significantly higher in group 1 indicating the onset of preovulatory luteinization. Luteinization after the hCG injection was more effective in group 1 resulting in significantly higher P levels. Fertilisation and cleavage rates were significantly higher in patients with normal PRL levels. High serum PRL levels therefore might indicate an interference in follicular and oocyte development leading to oocytes of inferior quality.
Purpose
The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic.
Methods
We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire.
Results
Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± β-blocker combination for Graves’ disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3–4 cytological results and papillary microcarcinoma.
Conclusion
This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
