This study aimed to investigate if moderate to vigorous physical activity (MVPA) and aerobic fitness are associated with cardiovascular risk factors in HIV+ children and adolescents. Sixty-five children and adolescents (8 to 15 years) provided minutes of MVPA measured by accelerometers and peak oxygen uptake (peak VO2 ) by breath-by-breath respiratory exchange. Cardiovascular risk factors were characterized by body fat, blood pressure, total cholesterol, HDL-c, LDL-c, triglycerides, glucose, insulin, C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α) and carotid intima-media thickness...

Carotid body tumors are rare neoplasms with malignant potential in 6% to 12.5% of cases, and surgical resection is the only cure. We present the cases of 2 female patients who had expanding, painless, right-sided neck masses; computed tomographic angiograms revealed Shamblin III tumors at the carotid bifurcation. Each patient underwent tumor resection with use of the retrocarotid dissection technique. The tumor specimens were histologically consistent with malignancy, and free margins were achieved. The patients remained free of symptoms, local recurrence, and metastasis 44 and 19 months after their respective procedures...

Carotid body tumor is an uncommon paraganglioma tumor in the head and neck region. Carotid angiography remains the gold standard for this tumor.Surgical treatment has been universally accepted as the main treatment of CBT, resection of it is technically challenging because of the location. In order to reduce the morbidity of intraoperative and postoperative complications,we summarize the surgical treatment and the prevention and treatment of complication of this neoplasm, after retrieving the domestic and foreign literature...

Carotid body tumors are rare childhood extra-adrenal paragangliomas. We present an 8-year old female with a neck mass mistaken as reactive lymphadenopathy. Computed tomography and magnetic resonance angiography, as well as preoperative embolization and balloon test occlusion, were utilized for planning and management. Surgical excision of the tumor was successful and pathological examination revealed a benign paraganglioma. Surgical treatment is curative for these benign lesions, however rare cases have presented years later with metastatic disease...

INTRODUCTION: A carotid body tumor is a rare neoplasm, generally benign, that predominantly affects people between their fourth and fith decades of life. It manifests as a pulsatile and generally painless cervical mass with firm consistency, located below the angle of the jaw. Clinically it can cause localized pain, dysphagia, hiccups, hoarseness and hypersensitive carotid body syndrome. Surgery is the treatment of choice, bearing in mind the possibility of malignant transformation, peritumoral invasion and metastasis...

Introduction: Among the U.S. population, the p81L SDHD (11q23) gene mutation is present in 6-36% of patients with sporadic carotid body tumor (CBT), but in familial cases is high as 80%. That is why the P81L mutation is used as a screening method for carotid body tumor in the U.S. Methods: We included 25 patients who underwent resection of a CBT from January 2010 to June 2015. After informed consent, a blood sample was taken for genetic testing on real-time polymerase chain reaction, in order to identify p81L mutation in the SDHD gene...

We present a case of unusual cardiac paraganglioma (PG) initially misdiagnosed as atypical carcinoid tumor of the lung and discuss key clinical and pathologic characteristics that guide surgical management of these rare chromaffin cell tumors. A 64-year-old female with persistent cough and back pain was found to have a 4 cm × 3 cm mass abutting multiple cardiopulmonary structures. A biopsy was performed at an outside institution and pathology reported "atypical neuroendocrine carcinoma, consistent with carcinoid"...

There has been no attempt to clarify the status of patients with carotid body tumor (CBT) in Japan. This multi-institutional survey analyzed patients with CBT throughout Japan by gathering information on these patients from institutions that performed head and neck surgeries. Information from a total of 150 patients from 25 institutions from the past 20 years was employed in the present survey. There were 87 females and 63 males, and their mean age was 48.0 years old. The most common chief complaint was a neck mass and the mean suffering period was 46...

The aim of this study was to assess whether the gender-specific pattern of fat mass (FM) distribution is related to gender differences in cardiometabolic risk factors. 207 healthy middle-aged Japanese were included in the study. We measured FM in the total body, trunk, and lower-body with dual-energy X-ray absorptiometry (DXA). The percentage of trunk FM (TFM) and lower-body FM (LFM) is noted as %TFM and %LFM, respectively. Other measurements included glucose and insulin during oral glucose tolerance test (OGTT), leptin, adiponectin, plasminogen activator inhibitor-1 (PAI-1), tumor necrosis factor- α (TNF- α ), C-reactive protein (CRP), and systemic oxidative stress marker...

BACKGROUND: Carotid body tumor (CBT) is a form of head and neck paragangliomas (HNPGLs) arising at the bifurcation of carotid arteries. Paragangliomas are commonly associated with germline and somatic mutations involving at least one of more than thirty causative genes. However, the specific functionality of a number of these genes involved in the formation of paragangliomas has not yet been fully investigated. METHODS: Exome library preparation was carried out using Nextera® Rapid Capture Exome Kit (Illumina, USA)...

A 41-year-old woman presented with a large painful and tender mass of the left side of her neck located just below the angle of the mandible. She was also complaining of frequent attacks of symptoms ranging from dizziness upon resuming the erect position to frank syncope. Color-coded duplex showed a large well-vascularized vascular mass at the level of the carotid bifurcation, suggesting the diagnosis of a carotid body tumor (CBT). A computerized tomographic angiography confirmed the diagnosis of a CBT, which measured 5...

PURPOSE: To correlate carotid dose and risk of carotid blowout syndrome (CBOS) after stereotactic body radiation therapy (SBRT), hypothesizing that carotid dose does not correlate with CBOS. METHODS AND MATERIALS: We retrospectively reviewed 186 patients with recurrent, previously irradiated head and neck cancer treated between January 2008 and March 2013. Patients treated early in our experience with incomplete dosimetry were excluded from analysis (n = 111). A total of 75 patients were identified, providing 150 carotid arteries for analysis...

In the present case report, a rare bilateral carotid body tumor (CBT) and the imaging and pathological features of a CBT are described. In the present report, a rare case of bilateral carotid body tumor, which developed in the bifurcation of the common carotid artery, and the clinical manifestations, imaging and pathological features of this CBT are summarized. The imaging cannot validate the diagnosis; however, imaging identified that the tumor exhibited an intact envelope. Immunohistochemical staining revealed that the tumor cells were strongly positive for cluster of differentiation 56, Syn and protein S-100, moderately positive for transcription factor E3, negative for cytokeratin and epithelial membrane antigen, and partial cells were weakly positive for Desmir (<5%)...

A 7 yr old female pit bull terrier was presented for a cervical soft tissue swelling located in the left jugular region. No abnormalities were present at physical examination or in the laboratory workup. Computed tomography and MRI scans showed a well-defined, ovoid, single mass in the left dorsal cervical region connected to the common carotid artery, histologically consistent with carotid body paraganglioma. The mass was surgically resected. Frameless stereotactic body radiation therapy with volumetric modulated arc therapy was set up as adjuvant treatment...

Herein we report the management of a giant, high-grade and vascular carotid body tumor in a young woman. She presented with slowly progressive neck swelling. Vascular imaging revealed a left-sided, high-grade giant carotid body tumor (> 8cm).  The tumor was completely excised by caudocranial subadventitial dissection. Histology of the tumor revealed a characteristic Zellballen pattern of the lesion, suggestive of a paraganglioma. The patient made an uneventful recovery. We also discuss newer insights regarding the management of such highly vascular lesions...

Carotid splaying, also known as the Lyre sign, is a widening of the carotid bifurcation due to the displacement of the internal carotid artery and the external carotid artery just distal to the point of divergence. This phenomenon is classically exhibited by highly vascularized carotid body tumors and, in rare cases, by cervical sympathetic chain schwannomas. Demonstration of the Lyre sign by a cervical vagal neurofibroma, however, is a unique occurrence that has not been previously documented in the literature...
