Prophylactic Central Neck Dissection in Papillary Thyroid Carcinoma: All Risks, No Reward.

J Surg Res 2021 Apr 7;264:230-235. Epub 2021 Apr 7.

Department of Surgery, The University of Alabama at Birmingham, Birmingham, Alabama. Electronic address:

Background: Central neck dissection (CND) remains a controversial intervention for papillary thyroid carcinoma (PTC) patients with clinically negative nodes (cN0) in the central compartment. Proponents state that CND in cN0 patients prevents locoregional recurrence, while opponents deem that the risks of complications outweigh any potential benefit. Thus, there remains conflicting results amongst studies assessing oncologic and surgical outcomes in cN0 PTC patients who undergo CND. Read More

Evaluation of Factors Associated with, and Outcomes for Patients with Non-Home Discharge Destinations Following Carotid Endarterectomy.

Ann Vasc Surg 2021 Apr 7. Epub 2021 Apr 7.

Department of Surgery, Pennsylvania State University, College of Medicine, Hershey, PA. Electronic address:

Introduction: Following a carotid endarterectomy (CEA) procedure, patients are discharged to their homes or other locations than home such as an acute care facility or skilled nursing facility based on their functional status and level of medical attention needed. Decision-making for discharge destination following a CEA to home or non-home locations is important due to the differences in survival and post-operative complications. While primary outcomes such as mortality and occurrence of stroke following CEA have been extensively studied, there is a paucity of information characterizing outcomes of discharge destination and the factors associated.

Breast cancer patients with a negative axillary ultrasound may have clinically significant nodal metastasis.

Breast Cancer Res Treat 2021 Apr 10. Epub 2021 Apr 10.

The Department of Surgery, The Royal College of Surgeons in Ireland, Dublin, Ireland.

Introduction: The non-invasive nature of the preoperative axillary ultrasound (AUS) fits the current trend of increasingly conservative axillary management. Recent publications suggest that early disease patients with clinically and radiologically negative axillae do not require sentinel lymph node biopsy (SLNB). This study aims to determine the true extent of axillary node disease in negative preoperative AUS patients. Read More

The Effect of Geometric and Hemodynamic Parameters on Blood Flow Efficiency in Repaired Tetralogy of Fallot Patients.

Ann Biomed Eng 2021 Apr 9. Epub 2021 Apr 9.

Institute of Biomedical Engineering, University of Toronto, Toronto, Canada.

Surgical repair of Tetralogy of Fallot (TOF) involves a series of steps to remove right ventricular outflow tract and pulmonary artery obstruction. However, the large degree of anatomic variability among preoperative TOF patients may impact the effectiveness of different repair strategies and, subsequently, different geometric modifications for different patients. This study investigates the relationships between geometric and hemodynamic parameters and mechanical energy efficiency for a patient-specific dataset of 16 postoperative TOF repairs, using morphometric and statistical shape analyses, as well as computational fluid dynamics simulations with physiologically-relevant inlet and outlet boundary conditions.

Prevalence of thyroid carcinoma in nodules with thy 3 cytology: the role of preoperative ultrasonography and strain elastography.

Thyroid Res 2021 Apr 9;14(1). Epub 2021 Apr 9.

European University Cyprus, 6 Diogenes Street, Engomi, 2404, Nicosia, Cyprus.

Background: Fine needle aspiration (FNA) cytology, the gold standard in assessing thyroid nodules, is limited by its inability to determine the true risk of malignancy in Thy 3 nodules. Most patients with Thy3 cytology undergo surgery to establish a histologic diagnosis. The aims of this study were to evaluate the prevalence of malignancy in Thy3 nodules, to examine the ultrasound (US) characteristics that are associated with a high cancer risk and to assess the role of real-time strain elastography.

Application of preoperative computed tomographic lymphography for precise sentinel lymph node biopsy in breast cancer patients.

BMC Surg 2021 Apr 9;21(1):187. Epub 2021 Apr 9.

Department of Breast Surgery, General Surgery, Qilu Hospital of Shandong University, Wenhua Xi Road No. 107, Jinan, 250012, Shandong, China.

Background: In light of the extensive application of sentinel lymph node biopsy (SLNB) in clinically node-negative breast cancer patients and the recently investigated failure of SLNB after lumpectomy, it has become important to explore methods for preoperative mapping of sentinel lymph nodes (SLNs) and their lymphatics to direct precise SLNB and improve the identification rate of SLNs.

Methods: Twenty-seven patients with suspected breast cancer based on the results of the clinical examination and imaging were enrolled in the study. Computed tomographic lymphography (CTLG) followed by CT three-dimensional reconstruction was performed to determine the localization of SLNs and lymphatics on the body surface preoperatively.
