...ever before. Diabetic neuropathy, a debilitating nerve disorder which can affect almost any part of the nervous system, occurs in nearly 50 percent of patients with diabetes. Diabetic peripheral neuropathy is found in 12 percent of insulin dependent diabetics and 32 percent of those who are not, equaling approximately 3 million people in the United States. (Chen et al. 2007) The number of patients with other neuropathies, such as autonomic, proximal, and focal, comprises the other 1 million diabetic neuropathy patients, most of whom suffer in pain from the dysfunction of the nervous system. (Chen et al. 2007) This disorder’s elusive nature is such that it can not only present in any part of the body but it can be completely without symptoms that the average patient would report to their physician. Since the patients themselves are less likely to naturally disclose their suffering through their assumption that their symptoms are not relevant to their diabetic condition, the physician’s role in the diagnosis and recognition of this disorder is even more critical. II. Definition and Types of Diabetic Neuropathy The most common type of diabetic neuropathy is peripheral, considered, more generally, sensorimotor. Peripheral neuropathy causes pain or loss of feeling in the toes, feet, legs, hands, and arms. (NIDDKD 2002) Specifically, distal symmetric polyneuropathy is the most common of peripheral types, causing nerve damage away from the center of the nervous system...

Phantom brain can be categorized as a mental disorder, and is assumed to originate from the stem of the region of amputation. There are three types of characteristic in the phantom complex. The first is phantom limb pain (PLP) which emphasis on a painful sensation in the spatial area of the missing limb. Phantom limb sensation(PLS) which is anytype of sensation in relation to the absent limb without any pain. Lastly is the description known as stump pain where the amputees pain is focused on the stump, (Anaseth,2001).

...Liceo de Cagayn university – graduate studies | Visual Perception Deficits | Cataract & Glaucoma | Submitted by: | Nadine Angelica C. Gadia – Casiño, RN | March 18, 2012Submitted to:Ms. Delia V. Realista, RN, MANProfessor | | I. Intoduction Cataract Cataracts are common and significant cause of visual defects all over the world. A cataract is an opacification or clouding of the lens of the eye. Cataracts develop because of the alteration of transport of nutrients and metabolism in the lens. This interferes with light transmission to the retina therefore affecting the ability to perceive images clearly. All cells of the lens formed in the lifetime is retained therefore prevalence of cataracts increase rapidly with aging. WHO estimates that cataracts account for 48% of reversible blindness worldwide, which translates to about 18 million people. Cataracts affect slightly more women than men. The Beaver Dam Eye Study in the US found that 23.5% of women and 14.3% of men had a visually significant cataract by the age of 65 years. Although cataracts can be surgically removed, in many countries surgical services are inadequate, and cataract remains the leading cause of blindness. Age is the greatest risk factor in the occurrence of cataracts. Cataract, though with unclear links, may be acquired through heredity and genetics (e.g., Wilson's disease, galactosaemia, myotonic dystrophy). Early formation of cataracts is associated with the following risk factors: ...

...Prospects for Thought Communication Kevin Warwick and Daniela Cerqui Department of Cybernetics, University of Reading, Whiteknights, Reading, RG6 6AY, UK Abstract In this paper we take a look at the realistic future possibility of thought communication. Technical details are presented on experimentation carried out thus far using implant technology and the route ahead involving brain-computer interfaces is described. Of importance in the paper is however the ethical issues raised by such a novel technological development. Discussion is centred on how this relates to previous technological innovations and their early acceptance, e.g. the telephone. 1. Introduction Technology is now becoming available which is opening up the realistic possibility of thought communication between individuals being achieved in the forthcoming decade, through the use of brain-computer implants. Indeed the first trials along these lines are even now occurring in several research labs [Kennedy et. al., 2000; Warwick et. al., 2004]. New technical methods presently being looked into (e.g. nanotechnology) are only likely to further enhance the results obtained thus far and speed up the rate of progress in this area. Witnessing the dawning of a completely new and revolutionary technical capability for humans raises a multitude of questions in terms of the effects on all aspects of society. It is interesting to consider what we can learn by looking back to relevant new directions when they have occurred...

...neuroanatomists in their choice of names for neuroanatomical structures— but, then, how could they have anticipated that Latin and Greek, universal languages of the educated in their day, would not be compulsory university fare in our time? To help you, I have provided the literal English meanings of many of the neuroanatomical terms, and I have kept this chapter as brief, clear, and to the point as possible, covering only the most important structures. The payoff for your effort will be a fundamental understanding of the structure of the human brain and a new vocabulary to discuss it. 51 Central nervous system Peripheral nervous system 3.1 General Layout of the Nervous System ISBN 0-558-78571-9 Divisions of the Nervous System The vertebrate nervous system is composed of two divisions: the central nervous system and the peripheral nervous system (see Figure 3.1).

...Common risk factors associated with arteriogenic dysfunction include diabetes mellitus , pelvic trauma , hypertension , nicotine and hyperlipidemia. Long distance cycling has been found to be a risk factor for vasculogenic and neurogenic erectile dysfunction. In some reports , diabetic men have been seen to have a greater incidence of fibrotic lesions of cavernous artery with intimal proliferation , calcification and luminal stenosis. Smoking tobacco or other forms of nicotine based products affects erectile function by retarding the arterial flow to the penis and also blocks relaxation of corporeal smooth muscle relaxation.

...antioxidant in the body was not defined until 1988. Lipoic acid is readily converted in the body to another compound called dihydrolipoic acid. Dihydrolipoic acid, or R-Dihydrolipoic acid, is the reduced form of lipoic acid that has more immediate effects than lipoic acid and has even more significant antioxidant effects than lipoic acid. Both of these antioxidants are particularly effective in destroying free radicals known as peroxynitrite radicals. These damaging compounds contain both oxygen and nitrogen and have been implicated in the development of chronic inflammation, nervous system diseases, pulmonary diseases, and arteriosclerosis. Lipoic acid acts as an antioxidant in the body and has been shown to have protective effects against nerve damage in diabetics, among other beneficial effects. Lipoic acid is believed to increase the antioxidant activity of other antioxidants, such as vitamin C and vitamin E. It has the unusual effect of acting as an antioxidant both in water-soluble and fat-soluble domains in cells and tissues. This is in contrast to vitamin C, which is only water soluble, and vitamin E, which is only fat soluble. When lipoic acid is combined with these other antioxidants, the...

...A Caucasian man with Hip Pain The management of pain can be tricky as sometimes-healthcare professions struggle between objective pain and associating the subjective pain which is what the patient says, “It is.” Understanding the Pathophysiology of pain and the cause of acute pain that lead to chronic pain is an essential aspect of managing pain. The nociceptive pain pathway is series of neurons that detect noxious stimuli that end up with pain; however, the pathway starts at the peripheral to the spinal cord and the brain (Stahl 2013). Knowing the pain pathway will help the PMHNP to understand the use of certain psychological drugs for the manage pain like Selective norepinephrine reuptake inhibitors (SNRI) for depression (Mehalick et al. 2016). According to the case study, the patient suffered from right hip pain that has been going...

...Case Study for Final Exam Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. The name myasthenia gravis, which is Latin and Greek in origin, literally means "grave muscle weakness." With current therapies, however, most cases of myasthenia gravis are not as "grave" as the name implies. In fact, for the majority of individuals with myasthenia gravis, life expectancy is not lessened by the disorder. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Certain muscles such as those that control eye and eyelid movement, facial expression, chewing, talking, and swallowing are often, but not always, involved in the disorder. The muscles that control breathing and neck and limb movements may also be affected. Myasthenia gravis is caused by a defect in the transmission of nerve impulses to muscles. It occurs when normal communication between the nerve and muscle is interrupted at the neuromuscular junction - the place where nerve cells connect with the muscles they control. Normally when impulses travel down the nerve, the nerve endings release a neurotransmitter substance called acetylcholine. Acetylcholine travels through the neuromuscular junction and binds to acetylcholine receptors which are activated and generate a muscle contraction. ...

Ferrari in 1987 (1) as an autologous transfusion component after an open heart operation to avoid homologous blood product transfusion, there are now over 5200 entries in the NCBI for PRP ranging in fields from orthopedics, sports medicine, dentistry, otolaryngology, neurosurgery, ophthalmology, urology, wound healing, cosmetic, cardiothoracic and maxillofacial surgery. The initial popularity of PRP grew from its promise as a safe and natural alternative to surgery. PRP advocates promoted the procedure as an organically based therapy that enabled healing through the use of one’s own natural growth factors. In recent years, scientific research and technology has provided a new perspective on platelets. Studies suggest that platelets contain an abundance of growth factors and cytokines that can affect inflammation,...
