That is, physicians and scientists should be able Keywords: Arteriosclerosis to separate what is fact and what is fancy. So while the terminology is less than 300 arguably the most lethal diseases in industrialized countries leading to years old, the lesions are thousands of years old. Hence the answer to sudden death, myocardialinfarction,heart failure, stroke, kidney failure, query #1 is: Fancy. Discussion: the current classication of arteriosclerosis, as dened the purpose of this review is to re-examine the topic of arterioscle- in classic textbooks of pathology (e. Atherosclerosis is a disease of elastic and Fact or Fancy #1: the lesions of arteriosclerosis are less than 300 years old. In 1755 Van Haller used the Greek term idiopathic or associated with diabetes mellitus and/or renal failure. In 1904 Marchand coined the term atherosclerosis as best we can tell, the current classication of arteriosclerosis comes [5]. MichaelFishbeinistherecipientofthe2015DistinguishedAchievementAwardof thickening of the arteriole (arteriolosclerosis), to name only the most the Society for Cardiovascular Pathology. The natural lesions include nonspecic media, while the other half of the references state that the intima is intimal thickening, frequently seen in temporal artery biopsies and also involved. To our surprise, we could nd no prior sclerosis is not purely a medial lesion, and apparently is not the le- reference to this pattern in coronary arteries. Therefore the answer to query #3 Also surprising was the fact that this calcication was not associated is: Fancy. So the progression and evaluation of clinically-signicant athero- sclerotic plaques may not involve the fatty streak. There is no question that inammation plays a role in the progression and complications of atherosclerosis [18]. Ath- erosclerosis has also been thought to be an infectious disease [19],ade- generative disease [20], a thrombogenic disease [20], and even a primary proliferative disease [21]. However, it is also quite clear and has been understood for over 100 years that the rst event in athero- genesis is low density lipoproteins entering the arterial wall [22]. Itis the presence of these lipoproteins that become oxidized that initiates the inammation seen in atherosclerotic plaques [23]. Hence atherosclerosis is a primary disease of lipids, not inamma- tion, so the answer to query #8: Fancy. Fact of Fancy #9: the concept that inammation plays a role in the progression of atherosclerosis is a new idea. Discussion: Recent research work has identied molecular and cel- lularpathways of inammation that participate in theprocess of athero- sclerosis [28]. While contemporary investigators continue to elucidate the details of the inammatory response in atherosclerotic disease, past investigators have noted the inammation and its importance in the progression and complications of atherosclerosis.

We previously published a suggested start for efforts in risk factors, yet have no clinically signicant disease. Furthermore, new risk factors are being identied all the time originate as fatty streaks, then progress to brous plaques, and nally (Table 2.

Hence the answer to query the authors reported that of 67 plaques with an eccentric lipid pool, #11: Fancy. Discussion: There has been the general notion that the smaller, non- occlusive plaque ruptures more frequently than large occlusive plaques, andthatmostcoronaryevents arerelatedtosuch smallerplaques. According to the authors, before the coronary event, the culprit lesions were actually small non- occlusive plaques. If one actually looks at the data from these studies (Table 4), about 50% of the culprit lesions showed less than 50% diame- ter stenosis (equal to 75% cross-sectional area stenosis. In these pathologic studies (Table 5), only 14% of plaque rupture with thrombosis occurred in arteries with less than 75% cross-sectional narrowing.

In spinal cord injury erectile dysfunction rings buy levitra extra dosage 60 mg, for example erectile dysfunction recreational drugs order generic levitra extra dosage online, risk is highest in the first five years after the injury erectile dysfunction viagra doesn't work buy levitra extra dosage american express. Other risk factors include dependence on alcohol or drugs, lack of a spouse or close support network, acess to lethal means, or a previous suicide attempt. The most important factors in preventing suicide are spotting depression early, getting the right treat- ments for it, and instilling problem solving skills. In theory, it may also alleviate some forms of neurogenic pain, a huge contributor to depression. In fact, aggressive treatment of pain problems is crucial to the prevention of depression. About 80 percent of people with multiple sclerosis report that fatigue significantly interferes with their ability to function. Paralysis Resource Guide | 96 2 Fatigue is also a prominent symptom of post-polio syndrome. These symptoms may be caused by the gradual wearing out of already weakened and damaged nerve cells. Some believe chronic fatigue syndrome, which affects about 500,000 people in the United States, may be related to undi- agnosed post-polio syndrome. Underlying medical problems such as anemia, thyroid deficiency, diabetes, depression, respiratory problems or heart disease may be factors in a persons fatigue. Also, medications such as muscle relaxants, pain drugs and sedatives can contribute to fatigue. Low fitness levels may result in too little energy reserves to meet the physical demands of daily life. Cardiovascular diseases are reportedly the leading cause of death for persons who have had a spinal cord injury for more than 30 years. They are generally more insulin resistant, which affects the bodys ability to transform blood sugar into energy, and can lead to heart disease, diabetes and other conditions. Contributing to the abnormalities are loss of muscle mass (atrophy), increase in body fat, and a harder time maintaining cardiovascular fitness. Some prevention strate- gies include: screening for blood sugar problems, healthy diet, no smoking, moderation with alcohol, and regular physical exercise. Cafeine, alcohol, smoking and a diet high in refned carbohydrates, sugar and hydrogenated fats rob your energy. Reach for the best-feeling thoughts, enjoy a laugh whenever you can, and structure relaxation time at least twice a day using yoga, meditation or prayer. There is a wonderful array of gadgets and timesavers on the market (see page 229 for more. For a person with post-polio, this could mean using a wheelchair instead of a walker. Some people beneft from stress management, relaxation training, membership in a support group or psychotherapy. Physical activity was once thought to worsen fatigue, but aerobic exercise may beneft those with mild disabilities. Others include astragalus, borage seed oil, bromelain, comfrey, echinacea, garlic, Ginkgo biloba, ginseng, primrose oil, quercetin, St. Since one of the side efects of both drugs is insomnia, they work best if taken in the morning and at noon. Paralysis Resource Guide | 98 2 Orthostatic hypotension is a condition that results in a decrease in blood pressure when sitting or standing up, causing light-headedness or fainting. It occurs more commonly after spinal cord injury at T6 or above, in response to lowered blood pressure. It occurs in many spinal cord injured individuals and may develop within days following the injury. Hypo/hyperthermia: Paralysis can cause the temperature of the body to fluctuate according to the temperature of the environment. Being in a hot room may increase temperature (hyperthermia); a cold room may decrease tempera- ture (hypothermia. This kind of pain can usually be diagnosed and treated so the discomfort is managed and confined to a given period of time. It is the kind of alarm that doesnt go away and is resistant to most medical treatments. Pain is a complicated process that involves an intricate interplay between a number of important chemicals found naturally in the brain and spinal cord. These chemicals, called neurotransmitters, transmit nerve impulses from one cell to another. Recent data also suggest that there may be a shortage of the neurotrans- mitter norepinephrine, as well as an overabundance of the neurotransmitter glutamate. During experiments, mice with blocked glutamate receptors show a reduction in their responses to pain. Morphine and other opioid drugs work by locking on to these receptors, switching on pain-inhibiting pathways or circuits, and thereby blocking pain. The dramatic changes that occur with injury and persistent pain underscore that chronic pain should be considered a disease of the nervous system, not just prolonged acute pain or a symptom of an injury. New drugs must be developed; current medications for most chronic pain conditions are relatively ineffective and are used mostly in a trial by error manner; there are few alternatives. Pain can lead to inactivity, which may lead to anger and frustration, to isola- tion, depression, sleeplessness, sadness, then to more pain. Its a spin cycle of misery with no easy exit, and modern medicine doesnt offer a wide range of help. Pain control becomes a matter of pain management; the goal is to improve function and allow people to participate in day-to-day activities. Types of pain: Musculoskeletal or mechanical pain occurs at or above the level of spinal cord lesion and may stem from overuse of remaining functional muscles after spinal cord injury or those used for unaccustomed activity. Central pain doesnt always show up right away; it may take weeks or months to appear and is often associated with recovery of some spinal cord function. Other irritations, such as pressure sores or fractures, may increase the burning of central pain. Psychological pain: Increased age, depression, stress and anxiety are associated with greater post-spinal cord injury pain. Paralysis Resource Guide | 100 2 Treatment Options for Neuropathic Pain: Heat and massage therapy: sometimes these are effective for musculoskeletal pain related to spinal cord injury. Acupuncture: this practice dates back 2,500 years to China and involves the application of needles to precise points on the body. While some research suggests this technique boosts levels of the bodys natural painkillers (endor- phins) in cerebrospinal fluid following treatment, acupuncture is not fully accepted in the medical community. Even light to moderate walking or swimming can contribute to an overall sense of well-being by improving blood and oxygen flow to tense, weak muscles. Visual imagery therapy, which uses guided images to modify behavior helps some people alleviate pain by changing perceptions of discomfort. Biofeedback: trains people to become aware of and to gain control over certain bodily functions, including muscle tension, heart rate and skin tempera- ture. One can also learn to effect a change in his or her responses to pain, for example, by using relaxation techniques. With feedback and reinforcement one can consciously self-modify out-of-balance brain rhythms, which can improve body processes and brain physiology. The patient triggers a pulse of electricity to the spinal cord using a small box-like receiver. Deep brain stimulation: is considered an extreme treatment and involves surgical stimulation of the brain, usually the thalamus. It is used for a limited number of conditions, including central pain syndrome, cancer pain, phantom limb pain and other types of neuropathic pain. Magnets: are usually dismissed as pseudoscience, but proponents offer the theory that magnetic fields may effect changes in cells or body chemistry, thus producing pain relief. Drugs: options for chronic pain include a ladder of drugs, starting with over the counter nonsteroidal anti-inflammatories such as aspirin, all the way to tightly controlled opiates such as morphine. Aspirin and ibuprofen may help with muscle and joint pain but are of minimal use for neuropathic pain. At the top of the ladder are Current medications for opioids, drugs derived from the poppy plant that are among the most chronic pain conditions oldest drugs known to human- are relatively inefective kind. They include codeine and and the options for treatment the king of opiates, morphine, are limited. While morphine is still the go-to therapy at the top of the treatment ladder, it is not usually a good long-term solution. It depresses breathing, causes constipation, fogs the brain and people develop tolerance and addiction for it. Scientists hope to develop a morphine-like drug that will have the pain-deadening qualities of morphine but without the drugs debilitating side effects. Anticonvulsants were developed to treat seizure disorders, but are also sometimes prescribed for pain. Carbamazepine (Tegretol) is used to treat a number of painful conditions, including trigeminal neuralgia. Approval of pregabalin, marketed as Lyrica, was based on two randomized, double-blind, placebo-controlled Phase 3 trials, which enrolled 357 patients. It also comes with a wide range of possible side-effects, including anxiety, restlessness, trouble sleeping, panic attacks, anger, irritability, agitation, aggression, and a risk for suicidal behavior. For some, tri-cyclic antidepressant drugs can be helpful for the treatment of pain. In addition, the class of anti-anxiety drugs called benzodiazepines (Xanax, Valium) act as muscle relaxants and are sometimes used to deal with pain. Botulinum toxin injections (Botox) which is used to treat focal spasticity, can also have an effect on pain. Nerve blocks: employ the use of drugs, chemical agents or surgical tech- niques to interrupt the transmission of pain messages between specific areas of the body and the brain. Types of surgical nerve blocks include neurectomy; spinal dorsal, cranial, and trigeminal rhizotomy; and sympathetic blockade. Physical therapy and rehabilitation: are often utilized to increase function, control pain and speed a person toward recovery. Surgeries: for pain include rhizotomy, in which a nerve close to the spinal cord is cut, and cordotomy, where bundles of nerves within the spinal cord are severed. Cordotomy is generally used only for the pain of terminal cancer that does not respond to other therapies. This surgery can be done with electrodes that selectively damage neurons in a targeted area of the brain. Numerous states have partially decriminalized marijuana for medical reasons but that does not exempt users from federal prohibition laws, nor does it allow doctors to prescribe marijuana. There is medical evidence, however, to support further study; marijuana appears to bind to receptors found in many brain regions that process pain information. Research in neuroscience will lead to a better understanding of the basic mechanisms of pain, and to more and better treatments in the years to come. Blocking or interrupting pain signals, especially when there is no apparent injury or trauma to tissue, is a key goal in the development of new medications. At the same time, the blood releases carbon dioxide, which is carried out of the lungs with exhaled air. Lungs themselves are not affected by paralysis, but the muscles of the chest, abdomen and diaphragm can be. As the various breathing muscles contract, they allow the lungs to expand, which changes the pressure inside the chest Paralysis Resource Guide | 104 2 so that air rushes into the lungs. If paralysis occurs in level C3 or higher, the phrenic nerve is no longer stimu- lated and therefore the diaphragm does not function. When the injury is between C3 to C5 the diaphragm is functional but respiratory insufficiency still occurs: the intercostals and other chest wall muscles do not provide the integrated expansion of the upper chest wall as the diaphragm descends during inspiration. People with paralysis at the mid-thoracic level and higher may have trouble taking a deep breath and exhaling forcefully. Because they may not have use of abdominal or intercostal muscles, these people also lose the ability to force a strong cough. Clearing Secretions: Mucous secretions are like glue, causing the sides of airways to stick together and not inflate properly. Some people have a harder time knocking down colds or respiratory infec- tions; they have what feels like a constant chest cold.

From the team leaders notebook When I frst started to work here, I couldnt understand a word Darren said.

She just tells Petra when she cant understand what shes saying and Petra points things out, sometimes even writes it down for her.

Nicki has spastic quadriplegia, so she has severe muscle stiffness in all four limbs. She cannot move her eyes so it is extremely diffcult for her to see a lot of things that happen around her.

Through all of this, it has been clear that Nicki is alert and intellectually able. From her frst attempts to respond yes or no to programs displaying choices, Nicki has learned to use her computer through a head operated touch pad. This enables her to work with various communication aids, including models with voice outputs, and automatic scanning systems that enable whole messages to be spoken. She can give information about things, answer and ask questions, and verbally contribute to conversations. Nicki has an aide, Joyce, who assists her with personal care in the workplace, which includes toileting, feeding, and ensuring she is repositioned regularly in her wheelchair.

However, it was John Little, an English orthopedic surgeon, who had equinus deformity due to polio, brought this disorder into light. He studied its causes and had related them to parturition; this first report by him was published in an obstetric journal. He got impressed with the results and practiced it in children with cerebral palsy. Because, the condition affects various parts of the brain and produces number of neurological deficits. Although according to the definition cerebral palsy is only a physical disability. However, they can have major associated deficits like poor intelligence and abnormal behavior. Further associated deficits affect special sense organs that can give rise to poor hearing and vision. Surprisingly, the list of deficits does not end here; these children also suffer from speech problem, seizures and so on. Not only this motor and other disorders can produce complications like contracture, dislocation, etc. Shall we not look into their educational aspect when many of them are trainable, and knowing that Ashtaawakra (according to author he is a cerebral palsy child in Indian mythology) had enlightened us with spiritual thoughts. Controlled emotions bridle with perfect intellectual direction and drive is the only path of successful management. Damage to the Developing brain: Because of this there are many uncertainties regarding the best possible development of the child. Interestingly, it is difficult to ascertain following a particular therapeutic intervention whether it is a natural development or it is due to the interven- tion, 4. Damage to brain affects motor system: the presence of motor system in animals, especially human beings, compared to plants and non living things have made all the difference in the progress and develop- ments on this planet. The mental faculties, definitely superior to all other animals, could not have made any progress without prehensile (hand skill) and the mobility present in them. Cerebral palsy is a static encephalopathy and occurs due to the damage (insult, injury) to developing (matur- ing) brain (embryo to 12 years. Risk factors-It has been considered that there are various risk factors present in mother and father of a child having cerebral palsy for example- Repeated abortions, too long or too frequent menses, malnourishment, drug abuse, etc. The damage to brain means damage to motor system which is comprised of many parts i. It is not only the motor system but also other parts of the brain may get affected. They give rise to various associated disorders like mental sub-normality; hearing, language and visual impairments, etc. Sometimes, the diagnosis of hereditary disorders may be very essential and all the efforts should be made to rule them out. The child having cerebral palsy should be assessed for the other neurological deficits also; severity of all deficits and presence of complications. Others How to Make Early Diagnosis of Cerebral Palsy A baby who has sustained damage to brain and / or has following clinical picture is likely to manifest full blown picture of cerebral palsy: A baby who remains dull most of the time and has less movements of limbs and head and / or ; cannot move the limb in a purposeful manner instead it just goes in an in-orderly manner ( usually in one particular direction only. Reduced head circumference Retarded growth Delayed social smile Persistence of primitive (early infancy) reflexes beyond 6 months. Abnormal turning of neck and head Asymmetry of body posture, movement and reflexes. Scientific reasons for the need to have early intervention A developing brain has lot of plasticity and if stimulated can develop neuronal synaptic proliferation and thereby can lead to development of nervous functions. It has been noted that if the abnormal brain pathways of the damaged brain are repeatedly stimulated, the channels get regularized, they get fixed and then to make alterations in them is very difficult. It is interesting to observe different kinds of development in different kinds of environmental stimulation of (3) genetically same and similar brain damaged people. This depends on the experience of the clinician to choose correct method for a particular problem keeping in mind over all improvement of the child. Not only this, professionals who know one particular modality of treatment prefer to treat with that modality only. In nutshell we can say that the professionals are biased with what they know and the families are confused as to what is the best for their child. Each system has some potentiality to improve certain deficits but most of them try to treat each and every problem of these children. But he hesitates to send him to other specialist and treats B, C and D problems also. He fails totally while managing these problems (say 0% in each B, C and D com- plaints. Because, in India, there is not enough infrastructure and manpower to provide multidisciplinary management at an accessible place. On an average if one centre caters to 250 children there should have been at least 10,000 rehabili- tation centers. Surprisingly, most of the capital cities of the country also do not have such centers. It includes both selection of method of treatment as well as application according to the age. Author feels that the following protocol is likely to be most beneficial in children having harmful spasticity, a major impairment: 1. Non-invasive Physiotherapy, occupational therapy Use of external appliances (4) Psychological management, special education, cognitive therapy, behavioral modification, self help skill, guid- ance etc. Pharmacotherapy: Brain tonics- for few months to few years following insult to brain, Medicines- for Spasticity, ataxia, seizures etc. However, they may not be good from their family point of view, because they may not be able to afford. However, in some cases these non ablative procedures may be the best suitable procedures from medical point of view. However, if the family cannot afford then the child cannot be left for non- development and to get into complications of spasticity. A judgment by the physician as to what is best for the family is very much expected and that would only motivate the family to sustain the long-term habilitation of the child. Dystonia in Cerebral Palsy; Sometimes dystonia are confused as psychiatric disorder. In hemidystonic cases and in a few diffuse cases stereo tactic thalamic-basal ganglionic stimulatory or ablative surgery can be considered. In these cases drugs is less preferred because systemic medication for life long is associated with other drug related complications. In authors series some control on dystonia could be achieved and in a few cases better use of the hand in bimanual activities was noticed. Sometimes diagnosis is uncertain in no risk babies or without the history of brain insult. However, without delay when the child has sustained brain damage or has delayed development, neurotrophic drugs (brain tonics) may be started. But, the parents must realize that medicine is not the ultimate; the definitive treatment is through neurostimulation.

Physiology Grey matter largely consists of neuronal cell Cell types bodies and white matter is white because of Two main types of cell compose the brain: the large number of myelinated axons erectile dysfunction diagnosis treatment discount levitra extra dosage generic. Neurons transmit nerve signals to and from the brain over Meninges and cerebrospinal fuid long distances erectile dysfunction related to prostate order levitra extra dosage 40mg visa. They consist of a cell body the brain and spinal cord are enveloped and (or soma) with branching dendrites (signal protected by the meninges food erectile dysfunction causes buy levitra extra dosage cheap, which consist receivers) and a projection called an axon impotence yoga pose order levitra extra dosage 60 mg with visa, of three layers: dura mater, arachnoid mater which conducts the nerve signal and trans- and pia mater. There it is fltered through the blood-brain barrier, which protects the brain from infections and toxins. Cerebral vasculature Two pairs of arteries provide the arterial blood supply of the brain: the internal carotid arter- ies in the neck and the vertebral arteries. They are interconnected through the circle of Wil- lis, which ensures a back-up circulation in the event of dysfunction of one of the arteries. The three main pairs of arteries that branch of from Figure 2: Propagation of a signal down an the circle of Willis and supply the cerebrum axon to the cell body and dendrites of the with arterial blood are the anterior, middle and next cell 7 Neurons can be classifed according to the the sympathetic nervous system.

There are several types of glioma, in- cluding astrocytomas, oligodendrogliomas and ependymomas. Other types of brain tumour that do not begin in glial tissue are meningiomas, schwannomas, craniopha- ryngiomas, germ cell tumours and pineal region tumours. Cerebral secondary tumours are metastatic tumours originating in other organs and are more common than primary ones (8. Brain infammation and infections Encephalitis refers to a difuse brain paren- chymal infammation mainly due to viral infections. Symptoms include headache, fever, confusion, drowsiness and fatigue, and in some cases seizures or con- vulsions, hallucinations, stroke, haemorrhag- ing and memory problems occur [9].

Choline is usually the study of primary brain tumours because labelled with 11C or 18F. With regard to the metabolic pathways and tumour features, the main families of avail- able radiopharmaceuticals are summarised in Table 5. High-grade tumours showed an early peak of activity followed by a sharp decline whereas low-grade tumours showed a more smoothed curve with a gradual decline [25].
