I Radioactive Seed Localization vs. Conventional Surgery for the Treatment of Mesenchymal Tumours: A Propensity Score Matching Analysis.

Purpose: Radioguided localization can assist the surgery of hard-to-find lesions. The aim was to evaluate the results of the I Radioactive Seed Localization (RSL) technique to guide a margin-free tumoral resection of mesenchymal tumours compared to conventional surgery and its influence in oncological outcomes.

Methods: Retrospective observational study of all consecutive patients who underwent I RSL for the surgery of a mesenchymal tumour from January 2012 to January 2020 in a tertiary referral centre in Spain.

Radioguided surgery of mesenchymal tumors with I seeds.

Introduction: Radioguided surgery uses radioactive substances to identify and remove hard-to-locate lesions. Mesenchymal tumors constitute a heterogeneous group of neoplasms derived from the mesoderm, including benign lesions and malignant sarcomas. The aim of this study was to evaluate the ability of I radioactive seeds to guide intraoperative localization of mesenchymal tumors, analyzing the complication rates and evaluating the margins of the surgical specimens retrieved.

Preoperative radio-guided localization of lung nodules with I-125 seeds: experience with 32 patients at a single institution.

Objectives: Videothoracoscopic visualization and/or palpation of pulmonary nodules may be difficult due to their location, small size or limited solid component. The purpose of this study is to present our experience with computed tomography (CT)-guided preoperative localization of pulmonary nodules by percutaneous marking with radio-labelled iodine-125 seeds.

Methods: A total of 34 pulmonary nodules were marked under CT with the placement of 33 radio-labelled iodine-125 seeds in 32 consecutive patients.

Utility of Peritoneal Scintigraphy in Peritoneal Dialysis Patients: One Center Experience.

Background: Peritoneal dialysis (PD) is the RRT of choice in 15% of patients with CKD and has multiple advantages over hemodialysis. PD leaks can prompt technique failure and dropout. Use of peritoneal scintigraphy (PS) for diagnosis of PD leaks has declined in favor of more complex and expensive tests.

Development of Thyroid Carcinoma During Treatment With Pembrolizumab in a Lung Cancer Patient.

Pembrolizumab, a programmed death 1 inhibitor, has been shown to have clinically significant efficacy in different types of cancer, providing long-term survival benefit for patients with lung cancer. Herein, we report the development of a primary thyroid cancer in a lung cancer patient that was being treated with pembrolizumab. Primary thyroid malignancy (and not only metastatic disease or immunotherapy-induced thyroiditis) should be considered in patients with lung cancer being treated with immune checkpoint inhibitors who develop new incidental thyroid lesions on imaging studies.

Histological changes secondary to wire coil placement in breast tissue and lymph nodes.

We describe the histological and immunohistochemical features of the changes produced by spiral coil localization wires in the breast parenchyma and lymph nodes of a total of 100 patients undergoing surgery for different breast lesions. Coil wires produced cystic lesions containing a hyaline, mucous-like, PAS-negative fluid. Cavities were lined by cells of variable morphology ranging from synovial-like cells (with a conspicuous epithelial appearance) to mononuclear or multinucleate histiocytic cells that expressed CD68, but were negative for keratins.

Infected renal cyst presented with pleural effusion in a woman with autosomal dominant polycystic kidney disease.

We present a 64-year-old woman with autosomal dominant polycystic kidney disease and hepatic cysts admitted to our hospital for high fever, intense coughing and right abdominal pain. The chest X-ray showed right pleural effusion suggestive of pneumonia. An abdominal ultrasound and computed tomography (CT) were done but did not show evidence of cyst infection or other abdominal complications.

Role of noninvasive antimyosin imaging in infants and children with clinically suspected myocarditis.

Unlabelled: Endomyocardial biopsy is an invasive procedure, often performed on children for the diagnosis of myocarditis, and is not without risk. Therefore, a noninvasive test of adequate diagnostic accuracy is highly desirable. We evaluated the role of antimyosin scintigraphy in infants and children with clinically suspected myocarditis.
