INTRODUCTION: Schwannomas of the descending loop of the hypoglossal nerve are very rare. They are slow-growing tumors that may masquerade a carotid body tumor. PRESENTATION OF CASE: A 60-year-old female was referred for a latero-cervical mass appearing as a chemodectoma at CT-scan. At operation, a 2cm mass arising from the descending loop of the hypoglossal nerve was resected en bloc with the loop itself and a functional lymphadenectomy was associated. Post-operative course was uneventful and the patient is free from disease recurrence at one year follow-up...

Children and young adults infected with HIV are at elevated risk for cardiovascular disease (CVD). However, scarce data exist on the utility of non-invasive methods to diagnose subclinical CVD, such as pulse wave velocity (PWV), a non-invasive measure of arterial stiffness. The objectives of this study were to assess the relationship of carotid-femoral PWV with subclinical atherosclerosis measured by carotid intima-media thickness (IMT), compare measurements to healthy controls, and evaluate variables associated with PWV in HIV-infected youth...

Interventions of cardiovascular disease should be implemented in early ages. But most studies were performed in middle aged or elderly adults because of the low prevalence in young, especially for women. We investigate the association between metabolic risk factors and subclinical atherosclerosis in young asymptomatic women adults, using carotid intima-media thickness (CIMT) as a marker of the atherosclerotic process.We performed a cross-sectional study of 950 Chinese young asymptomatic women adults (37.28 ± 5...

Intravascular foreign bodies are a known complication of medical and dental procedures. Dental anesthetic needles may be broken off and retained in the oropharynx. These needles have occasionally been reported to migrate through the oral mucosa in to deeper structures. Here we present the case of a 57-year-old man who had a retained dental needle that had migrated into his internal carotid artery. The needle was removed using endovascular techniques. To our knowledge, this is the first report of a retained dental needle being retrieved using this method...

BACKGROUND: Studies demonstrated that visit-to-visit variability in low-density lipoprotein cholesterol (LDLC) is an independent predictor of cardiovascular events in subjects with coronary artery disease. Whether visit-to-visit variability in LDLC levels affects subclinical atherosclerosis is unknown. This study sought to evaluate the role of visit-to-visit variability in LDLC levels on subclinical atherosclerosis. METHODS: We evaluated 162 type 2 diabetic patients with measurement of carotid intima-media thickness (IMT)...

Hypertension remains a major and growing public health problem associated with the greatest proportion of global cardiovascular (CV) morbidity and mortality. Although numerous factors contribute to poor blood pressure (BP) control and pseudo-resistance (i.e. unawareness, life-style habits, non-adherence to medication, insufficient treatment, drug-induced hypertension, undiagnosed secondary causes etc.), it is reported that true resistant hypertension (RH) is found in 10.1 % of patients treated for elevated BP...

We present an interesting scenario where a 64 years old male presented with a long standing painless, infra-auricular swelling, which had progressively increased in size. Based on the site, the clinical impression was of a salivary gland lesion and FNAC was performed. The smears were unusually cellular and had necrotic background. The cytological diagnosis was a cystic neoplasm of salivary gland, possibly mucoepidermoid carcinoma. Warthin's tumor was also kept in differential. However, the radiological investigations, which were made available after the FNAC report were conflicting with cytological diagnosis of a malignancy and were characteristic of a carotid body tumor, generally a benign neoplasm...

The application of sodium cyanide (NaCN) to the carotid body receptors (CBR) (CBR stimulation) induces rapid blood hyperglycemia and an increase in brain glucose retention. The commissural nucleus tractus solitarius (cNTS) is an essential relay nucleus in this hyperglycemic reflex; it receives glutamatergic afferents (that also release brain derived neurotrophic factor, BDNF) from the nodose-petrosal ganglia that relays CBR information. Previous work showed that AMPA in NTS blocks hyperglycemia and brain glucose retention after CBR stimulation...
