A 24-year old female patient with the history of pressure ulcers in distal extremities resulted in severe deformity will be reported. Her disease started when she was 9 years old and a similar history was found in her brother. In physical examination, pain and temperature sensations were impaired in distal extremities. Nerve conduction velocity showed impaired sensory and normal motor responses...
Schwannoma, or neurilemmoma, is a benign neoplasm that arises from Schwann cells, which surround peripheral, cranial, and autonomic nerve sheaths. Schwannoma has been reported to occur mainly as singular lesion of the sacral sciatic in young adults. Plexiform schwannoma, subtype rare known account for 2% 5% total schwannomas. upper extremities relatively mostly ulnar nerve. We report, with lite...
Hereditary sensory and autonomic neuropathy type II (HSAN2) is a condition that primarily affects the sensory nerve cells (sensory neurons), which transmit information about sensations such as pain, temperature, and touch. These sensations are impaired in people with HSAN2. In some affected people, the condition may also cause mild abnormalities of the autonomic nervous system, which controls i...
OBJECTIVE This study examines whether autonomic nerve autoantibodies (ANabs) are associated with development of autonomic neuropathy using a prospective study design. RESEARCH DESIGN AND METHODS A group of type 1 diabetic patients were followed prospectively with regard to autonomic nerve function on four occasions. At the third examination, 41 patients were tested for ANabs (complement-fixin...
Anesthesia providers may be called to treat injuries from chemical weapons or spills, for which prompt treatment is vital. It is therefore important to understand the mechanism of action of nerve agents and the resultant pathophysiology and to be able to quickly recognize the signs and symptoms of nerve agent exposure. This review article addresses the different types of nerve agents that are c...
Autonomic nervous system dysfunction, exaggerated inflammation, and impaired vascular repair are all hallmarks of hypertension. Considering that bone marrow (BM) is a major source of the inflammatory cells (ICs) and endothelial progenitor cells (EPCs), we hypothesized that impaired BM-autonomic nervous system interaction contributes to dysfunctional BM activity in hypertension. In the spontaneo...
In a series of studies to understand interactions between taste sensation and salivary gland function, we are pursuing experiments to determine the autonomic nervous system control of von Ebner's lingual salivary glands. Electrical stimulation of the glossopharyngeal nerve, which contains the parasympathetic nerve supply to von Ebner's glands, caused a reduction in secretory granules of the gla...
Schwann cells, from a variety of sources, are known to possess P2Y purinergic metabotropic receptors. However, it is not known if Schwann cells associated with autonomic nerve terminals possess such receptors and if so whether these receptors are activated by the endogenous release of ATP from the nerve terminals. We show that such Schwann cells in the vas deferens give evoked calcium transient...
