To treat patients with a catecholamine-secreting glomus jugulare tumor, perioperative management is important. Perioperative catecholamine hypersecretion causes severe problems in the treatment of a catecholamine-secreting glomus tumor. Therefore, a precise therapeutic strategy and perioperative management are required through collaboration of the endocrinology, anesthesiology, and endocrine su...

Paragangliomas, also known as glomus tumours or chemodectomas, are neuroendocrine tumours that originate from glomus cells in paraganglia. They are derived from the embryonal neural crest. The cells are part of the sympathetic nervous system and serve as chemoreceptors. They are located in the vascular adventitia of blood vessels which include the carotid bodies in the carotid artery bifurcatio...

Tumours of the glomus jugulare always raise diagnostic and therapeutic problems. We decided to review the pathology and clinical findings whilst reporting a typical case found on our neurology unit. After a brief review of the embryology, anatomy and histology of the glomus jugulare, the authors report the case of a patient who presented a recurrent intracranial form with involvement of several...

Glomus tumors are rare neoplasms that usually occur on the hands in a subungual location, or sometimes in palms, wrists or soles of the feet. They are described as purple/pink tiny painful lesions with a triad of pain, local point tenderness, and cold hypersensitivity. They are almost always benign, but rare malignant variants have been reported. They have also been reported to be present at un...

Glomus tumors are malformations of the neuromyoarterial system that commonly develop in the digits and cause exquisite tenderness, especially with cold temperatures. Treatment typically involves surgical excision, although there is a tendency to avoid aggressive resections, which may lead to aesthetically displeasing nail plate deformities. In a minority of patients, symptoms may persist and th...

A survey of the natural mycorrhizal potential has been carried out in a representative area of a desertified semiarid ecosystem in the southeast of Spain. Many indigenous plants from the field site were mycorrhizal, including the dominant Anthyllis cytisoides, which had high levels of colonization by arbuscular mycorrhizal fungi (AMF). Low numbers of AMF spores were present in the soil, althoug...

Under long-term hypoxia, noradrenaline (NA) content in the carotid body (CB) increases, suggesting that NA plays an important role in CB chemotransduction. However, it is unknown whether short-term hypoxia upregulates NA biosynthesis in CB. Therefore, we examined dopamine β-hydroxylase (DBH) expression in the CB of rats exposed to hypoxia (10% O(2)) for 0 to 24 hr with immunoblotting and immuno...
