Extractions: helpful? yes no Congenital Insensitivity to Pain: Congenital Indifference to Pain; Hereditary and Sensory Autonomic Neuropathy Types I-IV; HSAN Types I-IV In Congenital Insensitivity to Pain, there are structural abnormalities in peripheral nerves which are the peripheral pathways carrying electrical impulses from pain sensitive nerve endings in both superficial and deep tissues. In Congenital Indifference to Pain, the peripheral nerves are intact and the defect is apparently in the central structures such as the thalamus where painful impulses are normally interpreted. However, it is now thought that some individuals, formerly given a diagnosis of Congenital Indifference to Pain, have been shown by refined histological techniques, which look at the minute structures of bodies, to also have peripheral nerve abnormalities and are therefore examples of Congenital Insensitivity to Pain. Nevertheless, Congenital Indifference to Pain almost certainly exists as an independent condition, but is very rare. Congenital Insensitivity to Pain (of which types I to IV are generally accepted, with some other very rare conditions) is usually classified under the more general heading of Hereditary and Sensory Autonomic Neuropathy (HSAN). The various categories are distinguished according to clinical features, including age of onset, progressive or non-progressive, presence or absence of abnormalities of the autonomic nervous system, if the system is sympathetic (augmenting actions) or parasympathetic (inhibiting actions) and also according to the nature of structural abnormalities in peripheral nerves.

On Serendip Congenital Insensitivity to Pain with Anhidrosis (CIPA) is a rare disease which causes one to lose their feeling of pain. I read this article a couple of weeks ago about a girl who has this rare disease and is incapable of feeling pain and will never know what pain is. It intrigued me and sparked my web paper topic. I wanted to know everything there is to know about this disease and my research to give me answers, but, of course, this was not the case. The more and more I researched I began to wonder if this supports our notion of the "Brain =Behavior". There is so much more to learn about this fairly young disease and with that please take into account that these are sources off the internet and one could not know if they are fully accurate or not. As for the deep detail of the topic, such as names of different genes and etc, I do not fully understand their full meaning so I will write about what I took from all the different information about CIPA.
Neuropathy, Hereditary Sensory, Type IV HSAN IV; HSN IV; insensitivity to pain, congenital, with Anhydrosis; CIPA;Neuropathy, congenital Sensory, with Anhydrosis. Disorder Subdivisions http://webcenter.health.webmd.netscape.com/hw/brain_nervous_system/nord1144.asp
Extractions: The hereditary sensory neuropathies (HSN) include 4-6 similar but distinct inherited degenerative disorders of the nervous system (neurodegenerative) that frequently progress to loss of feeling, especially in the hands and feet. The classification of these diseases is complicated, and sometimes a source of disagreement among the experts. Hereditary sensory neuropathy type IV (HSN4) is a rare genetic disorder characterized by the loss of sensation (sensory loss), especially in the feet and legs and, less severely, in the hands and forearms. The sensory loss is due to abnormal functioning of small, unmyelinated nerve fibers and portions of the spinal cord that control responses to pain and temperature as well as other involuntary or automatic body processes. Sweating is almost completely absent with this disorder. Mental retardation is usually present.

Table of Contents Daniel Barbier The child's parents first realized something was wrong when their 4-month-old developed severe teething sores, and two months later those first teeth fell out. The boy frequently bled from his mouth and lost more teeth when gnawing on toys. Then he bit off part of his tongue, with nary a whimper. He had other symptoms: minor wounds that wouldn't heal, ulcerations between his fingers, and he didn't scream when receiving injections. When X-rays revealed a previously undetected skull fracture, doctors diagnosed a hereditary sensory and autonomic neuropathy (HSAN). The boy had HSAN4, or congenital insensitivity to pain. Two mutations in the neurotrophic tyrosine kinase receptor type I ( ) gene left his skin lacking nociceptors. The five HSANs, which vary by severity, age of onset, and mutated gene, vividly demonstrate that pain is vital. "People with inability to feel pain rarely make it past age 25. They become blind by rubbing their eyes, their teeth rot, and they break bones and suffer from burns," says Jeffrey A. Katz, associate director of the section for pain medicine at Northwestern University's Feinberg School of Medicine in Chicago. The original description of HSAN2 concerned a large family in Newfoundland whose many affected members had such numbness in their extremities that their digits detached. HSAN3 is even worse; because it impairs autonomic functions, individuals cannot control body temperature or blood pressure. They can't cry.

Extractions: Abdullah Alabousi It is very easy to recognize. It is known all over the world and it breaks all language barriers. It is referred to as pain. This unpleasant experience notifi es an individual that something is wrong in the body and needs to be corrected. It also serves a protective function by signalling the presence of harmful agents that may damage the body of an individual. However, pain is a complex perception that differs enormously amongst individuals (Tortora and Grabowski, 2003). PAIN, NOCICEPTION AND CIPA Unfortunately, there are only a few individuals in the world who are born with a disease that renders them unable to feel pain. This disease is known as Congenital Insensitivity to Pain with Anhidrosis, or CIPA (Theodorou et al., 2000). CIPA is extremely rare and there is currently no data available as to the prevalence and incidence of this disease. NGF AND TRKA MUTATIONS: In normal individuals, Nerve Growth Factor (NGF) stimulates the growth and supports the survival of autonomic sympathetic neurons as well as nociceptive sensory neurons, which transmit pain sensations to the spinal cord and the brain (Alberts et al., 2002). NGF consists of three types of polypeptide chains; alpha, beta and gamma, which interact to form the protein. The NGF beta chain is the one responsible for the nerve growth stimulating activity of NGF (Petruska and Mendell, 2004). NGF functions as a survival signal and acts by suppressing programmed cell death, apoptosis (Yuan and Yankner, 2000).

Extractions: A 10-year-old boy presented with history of non-healing ulcers at base of toes with subsequent loss of toes over the last three years ( Fig. 1 ). There were no draining sinuses or discharge of grains. Tone and power in limbs were normal. Sensory examination revealed generalized loss of pain and temperature sensations. Random blood sugar was normal. Nerve conduction studies showed sensorineural peripheral neuropathy. Tactile sensibility, vibration and position sense, and stereognosis were present. He had anhidrosis, habitual constipation and a low capacity overactive bladder on urodynamic study. His Intelligence Quotient was 75-80. There was no family history of similar illness. A diagnosis of Hereditary Sensory and Autonomic Neuropathy type IV (HSAN IV) was made. With bed rest, antibiotics and Eusol soaks the ulcers healed after four weeks (Fig. 2). To prevent recurrence, modified footwear for constant use was made for the child. Fig. 1. Feet deformed due to loss of all toes except the right great toe.

Abstract: Hereditary sensory autonomic neuropathy Type IV is an autosomal recessive disorder due to lack of maturation of small myelinated and unmyelinated fibers of peripheral nerves, which convey sensation of pain and temperature, therefore, resulting in self mutilation. There is anhidrosis due to lack of innervation of normal sweat glands resulting in recurrent episodes of hyperpyrexia. The clinical presentation of two children with this rare disease is described.

Neuroscience For Kids - Pain People with congenital insensitivity to pain usually have many injuries likepressure sores, damaged joints and even missing or damaged fingers! http://faculty.washington.edu/chudler/pain.html
Extractions: Pain and Why It Hurts You may not like it, but we need pain. Pain acts as a warning system that protects you. Pain says, "Warning, Warning....stop what you doing and do something else". For example, if you have your hand on a hot stove, pain tells you to stop touching the stove and remove your hand. In this way, pain protects your body from injury (or further injury if you have already hurt yourself). Pain also helps healing...because an injury hurts, you rest. There are some people who are born WITHOUT the sense of pain. These people have a rare condition called "congenital insensitivity to pain". Their nervous systems are not equipped to detect painful information. You may think this is a good thing....it is NOT. Without the ability to detect painful events, you would continue to cause injury to yourself. For example, if you broke a bone in your arm, you might continue using the arm because it did not hurt. You could cause further injury to your arm. People with congenital insensitivity to pain usually have many injuries like pressure sores, damaged joints and even missing or damaged fingers! So, what kind of things in the outside world can cause pain? Events that cause reactions are called
