Detection, Patterns, and Outcomes of Recurrent HPV-Positive Oropharyngeal Squamous Cell Carcinoma.

Importance: Recurrent human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is a relatively rare but serious disease with little empirical data. Previous works have studied patterns of recurrence in HPV-positive OPSCC, but only one has studied truly recurrent disease as opposed to persistent disease, and no work systematically analyzed posttreatment surveillance imaging strategies and how recurrences were detected.

Objective: To refine the understanding of HPV-positive OPSCC recurrence and inform optimal imaging surveillance strategies.

Predictive value of postoperative day 1 parathyroid hormone levels for early and late hypocalcaemia after thyroidectomy.

Purpose: Early parathyroid hormone (PTH) levels after total thyroidectomy can predict patients at low risk of hypocalcaemia who can be discharged early without calcium supplementation. For centres without facility to perform early PTH levels, PTH levels sent on the first postoperative day (POD1) may be an alternative. However, there is less data regarding optimal cut-off PTH levels for POD1 discharge.

Tissue sealant versus surgical drain following parotidectomy.

Purpose: Sialocele and salivary fistula are recognised complications of parotid surgery and have been reported to be more common with less extensive parotidectomy. We investigated the efficacy of tissue sealant(Cunniffe et al., 2019) as an alternative to surgical drainage in terms of length of hospital stay (LOS), cost, and incidence of wound complications.

Use of intraoperative neural monitoring for prognostication of recovery of vocal mobility and reduction of permanent vocal paralysis after thyroidectomy.

Introduction: The benefits of intraoperative neural monitoring (IONM) of recurrent laryngeal nerve (RLN) on post-thyroidectomy vocal cord palsy (VCP) rates are contentious. We wished to study impact of IONM on permanent VCP after thyroidectomy.

Methods: Retrospective review of prospective series of 1011 (1539 nerves-at-risk) patients undergoing thyroidectomy without (418, group 1) and with (583, group 2) IONM.

Perioperative magnesium levels in total thyroidectomy and relationship to hypocalcemia.

Background: We have previously shown an association between hypomagnesemia and hypocalcemia after thyroidectomy. However, little is known regarding the trend in magnesium levels in the days after thyroidectomy. Our objective was to study this trend in magnesium levels after thyroidectomy.

Outcome of Subclassification of Indeterminate (Thy-3) Thyroid Cytology into Thy-3a and Thy-3f.

Objectives: The British Thy system is a widely used classification system for reporting thyroid fine-needle aspiration (FNA) cytology. The Royal College of Pathologists in 2009 recommended the subdivision of the Thy-3 (indeterminate) category into Thy-3a (atypia) and Thy-3f (follicular neoplasm). Our objective was to examine the malignancy rates of Thy-3a and Thy-3f cases at our institution and to investigate whether the risk of malignancy in Thy-3a cases is reduced by FNA on a different occasion showing benign cytology.

Impact of Microcalcifications on Risk of Malignancy in Thyroid Nodules with Indeterminate or Benign Cytology.

Objective: Adverse sonographic features such as microcalcification may predict increased likelihood of malignant cytology by fine-needle aspiration and, accordingly, increased risk of malignant histology. Our objective was to study the predictive value of microcalcifications and other sonographic features for malignancy among thyroid nodules with benign or indeterminate cytology.

Study Design: Case series with chart review.
