The present study evaluated the effect of anagliptin on intimal hyperplasia following carotid artery injury in Sprague‑Dawley rats. Sprague‑Dawley rats weighing 280‑300 g were injured using a 2F Fogarty balloon embolectomy catheter. The rats were divided into injury‑(saline) and anagliptin‑(10 mg/kg/day) treated groups. vascular injuries were induced in the left carotid artery, followed by evaluation of neointima formation at 28 days. The right and left carotid arteries were harvested and evaluated with histological evaluation, and the plasma activity of glucagon‑like peptide 1 receptor (GLP‑1), stromal cell‑derived factor (SDF)‑1α, interleukin (IL)‑6, IL‑1β and tumor necrosis factor (TNF)‑α were detected by ELISA analysis...

A 58-year-old woman with a past medical history of a carotid body tumor, resected 4 months prior to presentation, was admitted to our hospital for treatment of a cardiac tumor that was identified on post-operative echocardiography and chest computed tomography. The cardiac tumor was surgically removed and identified pathologically as a paraganglioma, similarly to the carotid body tumor. Genetic analysis of both tumors identified a non-synonymous mutation in the succinate dehydrogenase (SDH) gene D, Exon4, c...

The overexpression of inflammasome components is correlated with diabetes‑associated complications. Oleanolic acid is a triterpenoid compound which is important in arterial injury. The present study evaluated whether oleanolic acid improved diabetic rat carotid artery injury through the inhibition of nucleotide‑binding domain, leucine‑rich‑containing family, pyrin domain‑containing‑3 (NLRP3) inflammasomes signaling pathways. A diabetic rat model was induced using streptozotocin (60 mg/kg) and underwent carotid artery injury...

The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a non-invasive method for measuring of the Pulsating Venous Pressure (VPT). We can measure VPT by the pulse phenomena...

OBJECTIVE: Carotid body tumors (CBTs) are rare hypervascular benign tumors that originate from the paraganglia at the carotid bifurcation. The red cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and mean platelet volume (MPV) may serve as markers in inflammatory, cardiovascular, and neoplastic diseases. However, their prognostic value in CBTs is unknown. The purpose of this study was to assess the leukocyte count, MPV, RDW, and NLR before and after surgery in patients with CBTs...

A 54-year-old woman was referred to thyroid evaluation because of a lump on the left side of the neck. Ultrasound exam did not show any thyroid abnormality, but highly perfused nodule at the left common carotid artery bifurcation was found. Because of the specific location, somatostatin receptor scintigraphy with Tc EDDA HYNIC-TOC was performed, starting with perfusion images and followed with SPECT/CT imaging at 2 and 4 hours. Well-perfused nodule with intensive accumulation and no other visible pathology in the body raised suspicion of a glomus tumor, consistent with MR exam performed later...

REVIEW
June Young Choi, Kyung Ho Kang
Bilateral axillo-breast approach (BABA) robotic thyroidectomy has been performed since 2008, and the indications of the BABA robotic operation has been widened to the robotic modified radical neck dissection (MRND). The indication for BABA robotic MRND is suspicious lateral neck metastasis of well-differentiated thyroid carcinoma, and the contraindication is far advanced carcinoma such as encasement of common carotid artery. Surgical procedures start from flap formation as a routine BABA robotic thyroidectomy and the lateral neck dissection is performed from level IV and Vb to level III and IIA...

BACKGROUND: Carotid body tumors (CBT) are rare entities for which surgical resection remains the gold standard. Given their hypervascularity, preoperative embolization is often used, however, controversy exists over whether a benefit is associated. Proponents of embolization argue it minimizes blood loss and complications. Critics argue cost and stroke outweigh benefits. This study aimed to investigate the impact of embolization on outcomes following CBT resection. METHODS: Patients undergoing CBT resection were identified using the Healthcare Cost and Utilization Project State Inpatient Database (HCUP-SID) for 5 states 2006-2013...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. It is characterized by multiple xanthogranulomatous masses throughout the body, predominantly in the tibia. One of the characteristic radiological findings of the lesions associated with ECD is a "coated artery," which is often observed in the aorta. Although approximately one-fourth of ECD cases involve the central nervous system (CNS), an intracranial-coated artery has only been reported in four cases. We report a case of ECD that involves the CNS and has the unique appearance of a coated vertebral artery (VA)...

BACKGROUND: Sclerostin is an inhibitor of the wingless-type mouse mammary tumor virus integration site family/β-catenin signalling pathway (WβcSP), which plays an important role in bone metabolism and in vascular biology. It could act protective regarding atherosclerosis development through its effect on WβcSP in vascular cells. Nevertheless, results of studies analyzing association between circulating sclerostin level (CSL) and atherosclerotic diseases (AD) are showing conflicting results...
