Background: Patients undergoing high-risk surgery are at a risk of sudden deterioration of their health. This study aimed to examine the feasibility of the development of two patient decision aids (PtDAs) to assist patients undergoing high-risk surgeries in informed decision-making about their medical care in a crisis.

Methods: This field testing implemented two PtDAs that met the international criteria developed by the researchers for patients before surgery.

Extraperitoneal mesh repair for ventral hernia has garnered attention and its rate has been increasing due to concerns for the potential complications of intraperitoneal mesh repair. Recently, robotic-assisted ventral hernia repair is highlighted as a solution to the technically demanding nature of laparoscopic transabdominal or enhanced-view totally extraperitoneal retrorectus ventral hernia repair. A 78-year-old man, who had undergone robot-assisted radical prostatectomy 10 months earlier, presented with an incisional hernia of European Hernia Society Classification M3W2, length 4 cm, width 5 cm with rectus diastasis.

Background And Object: The right nonrecurrent inferior laryngeal nerve (NRILN), which is usually associated with the right aberrant subclavian artery, is a risk factor of nerve injury during thyroid surgery. Therefore the presence of the NRILN should be diagnosed if possible before surgery. The aim of this study was to investigate the usefulness of computed tomography (CT) and ultrasonography (US) for preoperative diagnosis of the right-sided NRILN.

Anaplastic thyroid carcinoma (ATC) is the most aggressive of thyroid cancers whose treatment is not yet established and mortality is extremely high. Recent in vitro studies have shown that valproic acid (VA), a newly identified histone deacetilase (HDAC) inhibitor, induces apoptosis, modulates differentiation gene expression of thyroid tumors and enhances the sensitivity of anaplastic cancer cell lines to doxorubicin. We report a case of successful treatment of anaplastic thyroid carcinoma with a combination of oral valproic acid, chemotherapy consisting of cisplatin and doxorubicin, external and intra-operative radiation and surgery.
