Carotid body paraganglioma is a slow growing tumor of head and neck region. It can rarely be malignant in nature which is characterized by distant metastases on anatomical imaging. We share an interesting presentation of a malignant carotid body on F-18 FDG PET/CT in form of liver and skeletal metastases.

Signal Transduction Pathway Mediating Carotid Body Dependent Sympathetic Activation and Hypertension by Chronic Intermittent Hypoxia.

Function (Oxf)

Patients with obstructive sleep apnea (OSA) experience chronic intermittent hypoxia (CIH). OSA patients and CIH-treated rodents exhibit overactive sympathetic nervous system and hypertension, mediated through hyperactive carotid body (CB) chemoreflex. Activation of olfactory receptor 78 (Olfr78) by hydrogen sulfide (H2S) is implicated in CB activation and sympathetic nerve responses to CIH, but the downstream signaling pathways remain unknown.

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.

Introduction: The effect of mechanoreflex on central blood pressure (BP) is unclear, although the influence of metaboreflex has been investigated. A relatively small contribution of the mechanoreflex to the pressor response to exercise has been considered in humans because many studies have failed to isolate the mechanoreflex-mediated pressor response. In a recent study, we successfully isolated a mechanoreflex-mediated pressor response using static passive stretching (SPS) in the forearm.

Objectives: This study analyzed carotid artery remodeling characteristics in early carotid atherosclerosis (ECAS).

Methods: The 1021 participants were evaluated using ultrasonography and categorized into three groups: Group A, 391 participants with increased intima-media thickness (IMT); Group B, 300 participants with atherosclerotic plaque only on the carotid bulb (CB); and the control group (330 participants). The ratios of the diameters in the CB to those in the common carotid artery (D) and internal carotid artery (D) were defined as carotid index1 (CI) and 2 (CI).

Safety and Outcomes of Intravenous Thrombolysis in Acute Ischemic Stroke with Intracranial Artery Dissection.

Int J Stroke

January 2025

Department of Health Security System, Center for Health Security, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

background: : Intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) related to underlying intracranial artery dissection (IAD) poses potential risks, including the exacerbation of intramural hematoma and the rupture of the dissected arterial wall. However, the safety of IVT in this specific population remains uncertain.

aims:: This study aimed to assess whether IAD is associated with an increased risk of intracranial hemorrhage (ICH) following IVT and to evaluate its impact on functional outcomes.
