Stochastic activity networks (SANs) are a powerful and flexible extension of Petri nets. These models can be used for the modeling and analysis of various kinds and different aspects of distributed real-time systems. Similar to other classical extensions of Petri nets, SANs have some limitations for modeling complex and largescale systems. In order to remove these limitations and provide some h...
F AMILIAL dysautonomia (FD, also known as Riley-Day syndrome) is a rare (1:3,700 live births) autosomal recessive disorder, largely afflicting those of Ashkenazi Jewish descent. One of five hereditary sensory and autonomic neuropathies (HSAN, type III) influencing the development and survival of varied sensory, sympathetic, and parasympathetic neurons, FD is characterized by profound autonomic ...
Hereditary sensory and autonomic neuropathies (HSANs) are a genetically and clinically diverse group of disorders defined by peripheral nervous system (PNS) dysfunction. HSAN type III, known as familial dysautonomia (FD), results from a single base mutation in the gene IKBKAP that encodes a scaffolding unit (ELP1) for a multi-subunit complex known as Elongator. Since mutations in other Elongato...
Autonomic nervous system (ANS) dysfunction as a cause of disease is an increasingly recognized health problem, not only in the field of neurology, but also in cardiology, gastroenterology, endocrinology, urology, psychiatry, and primary care medicine. Patients may present with a myriad of symptoms including orthostatic intolerance, recurrent syncope, labile blood pressure, disorders of sweating...
Diabetic neuropathy is the most common neuropathy in industrialized countries, and it is associated with a wide range of clinical manifestations. The vast majority of patients with clinical diabetic neuropathy have a distal symmetrical form of the disorder that progresses following a fiber-lengthdependent pattern, with sensory and autonomic manifestations predominating. This pattern of neuropat...
Hereditary sensory and autonomic neuropathies (HSAN) are rare genetic syndromes of unknown etiology. They are seen in early childhood and are categorized into six different types by their symptoms. HSAN type 4 demonstrates autosomal recessive transmission pattern, with such major characteristics as loss of sense of pain, self-mutilation, anhydrosis and mental retardation. Sympathetic innervatio...
The authors evaluated epidermal nerve density (END) and thermal thresholds in 18 patients with chronic inflammatory demyelinating polyneuropathy (CIDP). END of patients with CIDP were lower than those of controls (4.5 +/- 2.9 vs 10.5 +/- 3.9 fibers/mm, p < 0.001). Reduced END were associated with autonomic symptoms. Thermal thresholds of patients with CIDP were elevated (88.2% for warm stimuli ...
Pain protects the body from damaging effects of harmful stimuli. Congenital insensitivity to pain is a rare inherited disorder characterized by diminished or absent sensitivity to pain, touch, and pressure that leads to frequent trauma and self-mutilation. The disorder is part of the hereditary sensory and autonomic neuropathy (HSAN) family, in which 5 types have been recognized. Research and c...
