Does a history of head and neck cancer affect outcome of endoscopic submucosal dissection for superficial esophageal squamous cell carcinoma?

Endosc Int Open 2020 Jul 16;8(7):E900-E910. Epub 2020 Jun 16.

Department of Gastroenterology, Cancer Institute, Hospital das Clinicas of University of Sao Paulo, Sao Paulo, Brazil.

Esophageal squamous cell carcinoma (ESCC) is the most common secondary tumor in patients with head and neck squamous cell cancer (HNSCC). Currently, endoscopic submucosal dissection (ESD) is the preferred approach to manage superficial ESCC, however, it remains to be elucidated whether patients with HNSCC and early ESCC managed by ESD have different outcomes. We retrospectively analyzed esophageal ESD for early ESCC from September 2009 to September 2017 and the following variables: demographics, tumor and specimen size, Paris classification, location, en bloc and R0 resection rates, overall survival (OS) and adverse events (AEs).

A Review of Methods for the Preservation of Laryngeal Nerves During Thyroidectomy.

Sisli Etfal Hastan Tip Bul 2018 18;52(2):79-91. Epub 2018 Jun 18.

Department of General Surgery, Bahcesehir University Faculty of Medicine, Istanbul, Turkey; Department of General Surgery, Sisli Memorial Hospital, Istanbul, Turkey.

The recurrent laryngeal nerve (RLN) provides motor innervation to the abductor and adductor muscles of the vocal cord, whereas the external branch of the superior laryngeal nerve (EBSLN) provides motor innervation to the cricothyroid muscle, which is the tensor muscle of the vocal cord. Both the RLN and the EBSLN are anatomically close to the thyroid and are therefore at risk of injury during thyroidectomy. These 2 laryngeal nerves must be carefully preserved during surgery to ensure that the function of the vocal cord is not impaired. Read More

Purpose: Reliable assessment of surgical skills is vital for competency-based medical training. Several factors influence not only the reliability of judgements but also the number of observations needed for making judgments of competency that are both consistent and reproducible. The aim of this study was to explore the role of various conditions-through the analysis of data from large-scale, simulation-based assessments of surgical technical skills-by examining the effects of those conditions on reliability using Generalizability theory.

Follicular dendritic cell sarcoma presenting as a thyroid mass: an unusual case report and literature review.

J Int Med Res 2020 Jun;48(6):300060520920433

Department of Thyroid Surgery, The First Hospital of China Medical University, Shenyang, Liaoning Province, China.

Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the germinal centers and is characterized by the neoplastic proliferation of spindled to ovoid cells. As there have been only five cases reported in the literature until now, the diagnostic and therapeutic information available to clinicians regarding thyroid FDCS is fairly limited. To our knowledge, this is the first case report of thyroid FDCS without a history of Hashimoto's thyroiditis. Read More
