Correct localization of the needle is of vital importance to guarantee successful puncture. The complexity of real US data increases the difficulties. A multi-scale random sample consensus (MS-RANSAC) algorithm is proposed in this paper to locate the needle in complicated 3D US data. The algorithm uses the radius difference between needle and other tubular human tissues to extract the correct needle location. The performance of classic RANSAC and MS-RANSAC are compared using three different datasets. Results show that MS-RANSAC can locate needle correctly in complicated condition where classic RANSAC cannot...

BACKGROUND: The low rate of progression associated with the potential complications of thyroidectomy makes active surveillance an increasingly recommended management in low-risk papillary microcarcinomas of the thyroid (PMT). The objective of this study was to report the results of fine needle aspiration (FNA) of nodules ≤ 1 cm with highly suspicious appearance on ultrasonography (US) in patients who are potential candidates for active surveillance. METHODS: We revised thyroid nodules ≤ 1 cm with highly suspicious appearance on US in patients without known distant metastases, suspicion of extrathyroid extension, or suspicious lymph nodes on US...

OBJECTIVE: To evaluate the diagnostic performance of two different shear wave elastography (SWE) techniques in distinguishing malignant breast lesions from benign ones. MATERIALS AND METHODS: From March 2016 to May 2016, a total of 153 breast lesions (mean diameter, 16.8 mm±10.5; range 4.1-90.0 mm) in 153 patients (mean age, 46.4 years±15.1; age range 20-86 years) were separately performed by two different SWE techniques (i.e. T-SWE, Aplio500, Toshiba Medical System, Tochigi, Japan; and S-SWE, the Aixplorer US system, SuperSonic Imagine, Provence, France)...

Importance: In 2014, the US Department of Health and Human Services decided that its 1981 exclusion of transsexual surgical treatments from Medicare coverage was based on outdated, incomplete, and biased science and did not reflect current evidence or standards of care, and the exclusion was therefore lifted. As a direct result of this decision, surgeons nationwide are seeing an increase in consultations for surgical therapy to help transgender and gender-nonconforming individuals. Although some clinicians may have the technical training for such surgical procedures, in many cases, they may not have a full understanding of the complex and comprehensive care required to provide optimal health care for transgender individuals...

Virtual surgical planning technology in head and neck surgery is witnessing strong growth. In the literature, the validity of the method from the point of view of accuracy and clinical utility has been widely documented, especially for bone modelling. To date, however, with its increased use in head and neck oncology, and consequently the increased need for bone and soft tissue reconstruction, is important to carry out the virtual programme considering not only bone reconstruction but also all aspects related to the reconstruction of soft tissue using composite flaps...

A 30-year-old Japanese woman presented at our hospital with a pancreatic tumor. Contrast-enhanced CT revealed a tumor with a 12-cm diameter in the pancreatic body and tail. In the preoperative setting, endoscopic ultrasound-guided fine-needle aspiration permitted a histopathological diagnosis of solid pseudopapillary neoplasm. Twhe patient underwent laparoscopic distal pancreatectomy with splenectomy. Our procedure involved three steps. Firstly, the splenic artery was occluded to block inflow of blood to the tumor...

PURPOSE OF REVIEW: There are few randomized controlled studies to guide the treatment of advanced cutaneous squamous cell carcinoma. The existing treatments are mostly based on case reports and small case series. Here we review recently available insights concerning the treatment of locally advanced and metastatic squamous cell carcinoma, with a special emphasis on novel targeted therapy and immunotherapy. RECENT FINDINGS: Surgery and combination of chemotherapy and radiation therapy have been long considered the gold standard options for advanced squamous cell carcinoma...

Renal cell carcinoma accounts for 3% of adult solid malignant tumours. Approximately 25% of the patients present with metastatic disease at presentation. In the era of immunotherapy (interferon alpha-2b and interleukin-2), studies showed significant survival benefit with cytoreductive nephrectomy (CRN) followed by interferon alpha-2b than interferon alpha 2-b alone. Introduction of targeted therapies (vascular endothelial growth factor receptor-tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors) in 2005 generated a great interest in the management of metastatic renal cell carcinoma (mRCC) as these drugs exhibited tumour shrinkage in the primary tumour as well as in the metastatic site/s...

In recent years, brachial plexus anesthesia techniques for upper limb surgery have been used more and more commonly on children; however, the patient is typically under deep sedation or general anesthesia. For eligible, cooperative children, surgery can also be performed using regional blocks while the patient is awake. We present 5 cases in which Ultrasound (US)-guided infraclavicular brachial plexus blocks (ICB) were used on children for hand or forearm surgery. Surgical anesthesia was achieved in all patients and surgery was completed uneventfully using brachial plexus anesthesia, without need for deep sedation...

Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures. We present our initial experience with two cases operated on using O-arm-based spinal navigation at the Clinic of Neurosurgery in St George University Hospital, Plovdiv, Bulgaria. In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation. In the second case, we performed O-arm-navigated corpectomy of the fifth cervical vertebra and anterior spinal reconstruction and fusion with titanium expandable mesh and cervical plate in connection with degenerative narrowing of the cervical spinal canal that lead to clinically manifested myelopathy...

BACKGROUND: Uterine fibroids are a common problem for reproductive-aged women, yet little comparative effectiveness research is available to guide treatment choice. Uterine artery embolization and magnetic resonance imaging-guided focused ultrasound surgery are minimally invasive therapies approved by the United States Food and Drug Administration for treating symptomatic uterine fibroids. The Fibroid Interventions: Reducing Symptoms Today and Tomorrow study is the first randomized controlled trial to compare these 2 fibroid treatments...

BACKGROUND: The aim of the study was to evaluate the results of ultrasonography (US)-guided percutaneous radiofrequency ablation (RFA) in hyperparathyroid patients who refused surgery or had high surgical risks. PATIENTS AND METHODS: Five patients with hyperparathyroidism (HPT) underwent US-guided RFA for a single hyperfunctioning parathyroid lesion. Post-ablation serum calcium and parathormone (PTH) assays were performed. All patients underwent imaging studies 6 months after the ablation to visualize the post-ablation change in the size of the treated parathyroid lesions...

PURPOSE: This study was designed to assess the outcomes of subcentimeter thyroid nodules with highly suspicious ultrasonography (US) features and to investigate the predictive factors associated with malignancy and aggressive biological behavior to determine appropriate candidate factors for active surveillance. METHODS: Between June 2011 and December 2013, 1866 subcentimeter thyroid nodules with highly suspicious US features that were subjected to US-guided fine needle aspiration and subsequent surgery or US follow-up of at least 2 years were evaluated...

Importance: The Second Universal Definition of Myocardial Infarction (MI) divides MIs into different types. Type 1 MIs result spontaneously from instability of atherosclerotic plaque, whereas type 2 MIs occur in the setting of a mismatch between oxygen demand and supply, as with severe hypotension. Type 2 MIs are uncommon in the general population, but their frequency in human immunodeficiency virus (HIV)-infected individuals is unknown. Objectives: To characterize MIs, including type; identify causes of type 2 MIs; and compare demographic and clinical characteristics among HIV-infected individuals with type 1 vs type 2 MIs...
