Clinical studies in relatively small numbers of patients have evaluated the efficacy of bromocriptine treatment in patients with systemic lupus erythematosus (McMurray et al. This is not surprising, given the degree of reciprocal interactions between the immune system and the central nervous system. Although the linkage between psychological stress and disease was recognized in the early 19th century, the study of actual risk has been challenging due to differences in definition of stressors, limited follow-up, and generally small sample sizes (J. A meta-analysis of 14 studies showed a significant increase in risk of exacerbation of multiple sclerosis following stressful life events (Mohr et al. However, a number of other studies have shown equivocal results or improvement of multiple sclerosis, suggesting that different stressors may influence disease outcomes in different ways (Nisipeanu & Korczyn, 1993; Goodin, 2004). The interactions between the immune and nervous systems and the potential mechanisms by which psychological stress can influ ence autoimmune diseases are still poorly understood; however, laboratory studies are providing some mechanistic insights. Changes in disease susceptibility were associated with decreased T cell proliferation and increased macrophage activity. Table 5 lists the most important systemic autoimmune diseases that are, in general, clinically manifest in multiple organs; Table 6 categorizes most of the organ-specific autoimmune diseases based on the organ system that is involved. It remains a matter of debate how to prove that a given disease is indeed an autoimmune disease. Other diseases, such as coeliac disease and inflammatory bowel diseases, have an auto immune component, but the role of autoimmunity in their patho genesis is not clear. Even though a number of diseases have been suspected to have autoimmune etiology, available evidence is insufficient to establish a close relationship in many instances. This book addresses chemical risk, but other relevant environ mental risk factors possibly able to cause autoimmune disorders, such as ultraviolet radiation, will be briefly taken into account in a specific section (section 8. Primary Addison disease is relatively rare, with a prevalence of 5?15 per 100 000 in Europe and the United States (Jacobson et al. This disease is usually slowly progressive, and patients generally present with such manifestations as malaise, anorexia, hyperpigmentation, hypotension, and salt wasting. The laboratory diagnosis primarily rests on the lack of a cortisol response to adrenocorticotropic hormone stimulation. The diagnosis may be supported by radiological procedures, revealing small, non-calcified adrenal glands, or by detection of autoanti bodies to adrenal cortical cells. These autoantibodies are directed to enzymes involved in steroid synthesis, such as 21-hydroxylase. Anti body deposition and complement fixation to adrenal cortical cells is apparent upon microscopic examination. Nevertheless, the exact role of autoantibodies and/or T cells in the pathogenesis of Addison disease remains elusive. The clinical presentation may vary greatly depending on the type and size of vessels involved. A categorization of primary vasculitides, according to the 1993 Chapel Hill Consensus Conference definitions, distinguishes large vessel, medium-sized vessel, and small-vessel vasculitides. In the case of Wegener granulomatosis, presentation often includes signs of chronic inflammation of the upper and/or lower respiratory tract and, in particular, bloody nasal discharge. Patients with Churg-Strauss syndrome usually have mani festations such as nasal obstruction due to polyposis nasi, asthma, diarrhoea, and eosinophilia. The diagnosis is based on clinical find ings and on detection of antineutrophil cytoplasmic autoantibodies in the circulation. The final diagnosis depends on biopsy evidence of vasculitis in the affected organs, in particular the kidney, nose, skin, lungs, nerve, and/or muscle. The clinical manifestations of this type of drug induced vasculitides range from single organ involvement, most commonly the skin, to life-threatening systemic disease. The condition is primary if associated autoimmune disease (especially systemic lupus erythematosus) has been excluded. Up to 15% of patients with systemic lupus erythematosus will have antiphospholipid syndrome, and about 50% of patients with antiphospholipid syndrome have systemic lupus erythematosus. The clinical features of antiphospholipid syndrome result from thrombo embolism of large vessels, thrombotic microangiopathy, or both. By far the most common manifestation is deep venous thrombosis of the legs, with or without pulmonary emboli. Arterial thrombosis mostly results in strokes and transient ischaemic attacks in the brain or in myocardial infarction. In the case of adverse pregnancy outcomes in women with antiphospholipid syndrome, thrombotic events in the placenta may cause poor placental perfusion. While most patients with antiphospholipid syndrome present with a single thrombotic event, a minority present with multiple simultaneous vascular occlusions throughout the body, often resulting in death. For diagnosis of antiphospholipid syndrome, the Sapporo classification criteria can be used (Wilson et al. A definite antiphospholipid syndrome is considered to be present if at least one clinical criterion and one laboratory criterion are met. The clinical criteria include vascular thrombosis, arterial, venous, or small-vessel thrombosis, and complications of pregnancy, such as unexplained death after the 10th week of gestation, premature birth before the 52 Clinical Expression of Human Autoimmune Diseases 34th week of gestation, or at least three unexplained consecutive spontaneous abortions before the 10th week of gestation. Activation of endothelial cells or platelets, oxidant-mediated injury of the vascular endothelium, interference with the function of phospholipid-binding proteins involved in the regulation of coagulation, or events similar to those in heparin induced thrombocytopenia have been proposed as pathogenetic mechanisms, and supporting in vitro evidence has been suggested for each possibility. The mere presence of antiphospholipid antibodies is considered insufficient to generate thrombosis; a second event may be required. Such events may include vascular injury, medication, atherosclerotic disease, or infections. The prevalence of clinically diagnosed coeliac disease is estimated to be 1:1000; however, screening trials suggest a prevalence of up to 1:100. The gluten-sensitive enteropathy results in weight loss, diarrhoea, symptoms due to nutritional deficiencies, such as anaemia and fatigue, and growth failure. These symptoms are the result of the mucosal lesions that develop and eventually result in villous atrophy. Coeliac disease may also present as extraintestinal manifes tation, such as dermatitis herpetiformis, or may remain clinically silent. Firstly, there is the appearance of flat small intestinal mucosa with the histological features of hyperplastic villous atrophy while the patient is still eating adequate amounts of gluten. Secondly, there should be unequivocal and full clinical remission after withdrawal of gluten from the diet. Altogether, coeliac disease is a typical example of an environmental factor in this case gluten triggering an autoimmune antibody response, although this autoim mune response is not maintained in the absence of the environmental trigger. Diabetes mellitus type 1 is one of the most common of the autoimmune diseases, with a prevalence of about 200 per 100 000 (Betterle et al. Onset of disease is typically during childhood or adolescence and peaks between 10 and 14 years. The clinical features of insulin-dependent diabetes mellitus result from derangement of insulin function and include polyuria, polydipsia, polyphagia, and ketoacidosis. Long standing diabetes is associated with renal insufficiency, blindness due to retinopathy, neuropathy, and atherosclerotic events such as myocardial infarction, cerebrovascular accidents, and gangrene of an extremity. Indeed, about 90% of Caucasian children will have at least one of these antibodies at the time of diagnosis. However, these antibodies are most valuable as tools to identify those at risk of developing insulin-dependent diabetes mellitus. Pancreatic lesions show evidence of lymphocytic infiltration in the islets in early diabetes. Whether any of the autoantibodies are involved in the pathogenesis of disease remains unclear. Environmental factors have been suggested as triggers for the autoimmune response. These suggested factors include viral infec tions, infant feeding practices, toxins such as N-nitroso derivates, vaccinations, and arsenic exposure, but for the most part evidence supporting these links is lacking. Patients present with respiratory insufficiency due to alveolar haemorrhage, rapidly progressive renal insufficiency, or both. Early diagnosis is mandatory in order to prevent end-stage renal disease or death.

A network of special cells in the heart muscle conducts electrical impulses that coordinate contraction skin care victoria bc buy decadron 8 mg line, causing the heart to beat rhythmically acne keloidalis cure cheap decadron amex. Cardiac arrest occurs when the this causes the heart to lose the ability to beat rhythmically skin care di jakarta purchase decadron without prescription, electrical impulses that control the heartbeat or to stop beating altogether (Figure 3-3) acne 6dpo discount decadron online mastercard. Every organ in the body needs a steady supply of oxygen in order to work properly, and the heart is no exception. Severe trauma, electric shock and drug overdose are other potential causes of cardiac arrest. Although cardiac arrest is more common in adults, it does occur in young people as well. The 4-6 minutes: Brain damage can begin most common causes of cardiac arrest in children 8-10 minutes: Brain damage and infants are breathing emergencies, congenital can become irreversible heart disorders and trauma. Without oxygen, 40 20 brain damage can begin in about 4 to 6 minutes, 35 25 and the damage can become irreversible after 30 about 8 to 10 minutes (Figure 3-4). Death occurs within a matter of minutes if the person does not receive immediate care. When you check the person, you will find that the person is not responsive and not breathing, or only gasping. People who have a history of cardiovascular disease or a congenital heart disorder are at higher risk for sudden cardiac arrest. However, sudden cardiac arrest can happen in people who appear healthy and have no known heart disease or other risk factors for the condition. A person who experiences sudden cardiac arrest is at very high risk for dying and needs immediate care. First Aid Care for Cardiac Arrest When a person experiences cardiac arrest, quick action on the part of those who witness the arrest is crucial and gives the person the greatest chance for survival. In the Cardiac Chain of Survival, each link of the chain depends on, and is connected to , the other links. Four out of every five cardiac arrests in the United States occur outside of the hospital. That means responders like you are often responsible for initiating the Cardiac Chain of Survival. If you think that a person is in cardiac arrest: Have someone call 9-1-1 or the designated emergency number immediately. This squeezes (compresses) the heart between the breastbone (sternum) and spine, moving blood out of the heart and to the brain and other vital organs. In V-fib, the heart muscle simply quivers (fibrillates) weakly instead of contracting strongly. For example, if the person is on a soft surface like a sofa or bed, quickly move him or her to the floor before you begin. If you have arthritis in your hands, you can grasp the wrist of the hand positioned on the chest with your other hand instead. This will let you push on the chest using a straight up-and-down motion, which moves the most blood with each push and is also less tiring. Maintain a smooth, steady down-and-up rhythm and do not compressions can help you to pause between compressions. Once you have given 30 one and two and three and four and compressions, give 2 rescue breaths. For an adult, tilt the head to a past-neutral number and come up as you say position (see Table 3-1). This will help you to keep a breaths to find a breathing barrier or learn how to use it. After you finish giving 2 rescue breaths, return to Incorrect technique or body position giving compressions as quickly as possible. The process of can cause your arms and shoulders giving 2 rescue breaths and getting back to compressions to tire quickly when you are giving should take less than 10 seconds. Table 3-2 describes how to troubleshoot your upper body to compress the special situations when giving rescue breaths. Avoid rocking back and forth, because rocking makes your compressions less effective and wastes your energy. Also avoid leaning on the chest, because leaning prevents the chest from returning to its normal position after each compression, limiting the amount of blood that can return to the heart. Roll the person onto his or her side and clear the mouth of fluid using a gloved finger or a piece of gauze. However, in a child, you open the airway by tilting the head to a slightly past-neutral position, rather than to a past neutral position (see Table 3-1). Rather than compressing the chest to a depth of at least 2 inches as you would for an adult, you compress the chest to a depth of about 2 inches for a child. Also, for a small child, you may only need to give compressions with one hand, instead of two. Give compressions by using the pads of your fingers to compress the chest about 1? When you give rescue breaths, open the airway by tilting the head to a neutral position (see Table 3-1). Again, avoid touching the person, because anyone who is touching the person while the device is delivering a shock is at risk for receiving a shock as well. These pads should be used on children up to 8 years of age or weighing less than 55 pounds. If you cannot position the pads this way without them touching (as in the case of an infant or a small child), position one pad in the middle of the chest and the other pad on the back between the shoulder blades (Figure 3-8). Working as a team can lead to a better chance of survival for the person in cardiac arrest, by reducing responder fatigue and minimizing interruptions to chest compressions. Trained responders can share the responsibility for giving compressions, switching off every 2 minutes, which reduces fatigue and leads to better-quality compressions. Working as a team can lead to a better chance of survival for the person in cardiac arrest. Note: If the frst rescue breath does not cause the chest to rise, retilt the head and ensure a proper seal before giving the second rescue breath. If the second breath does not make the chest rise, an object may be blocking the airway. After the next set of chest compres sions and before attempting rescue breaths, open the mouth, look for an object and, if seen, remove it using a fnger sweep. Continue giving sets of 30 chest compressions and 2 rescue breaths until: You notice an obvious sign of life. If the second breath does not make the chest rise, an object may be blocking the airway. After the next set of chest compressions and before attempting rescue breaths, open the mouth, look for an object and, if seen, remove it using a fnger sweep. Continue giving sets of 30 chest compressions and 2 rescue breaths until: You notice an obvious sign of life. Note: If the frst rescue breath does not cause the chest to rise, retilt the head and ensure a proper seal before giving the second rescue breath. If the second breath does not make the chest rise, an object may be blocking the airway. Continue giving sets of 30 chest compressions and 2 rescue breaths until: You notice an obvious sign of life. Choking occurs when the airway becomes either C partially or completely blocked by a foreign object, such as a piece of food or a small toy; by swelling in the mouth or throat; or by fluids, such as vomit or blood. A person who is choking can quickly become unresponsive and die, so it is important to act quickly. Risk Factors for Choking Certain behaviors can put a person at risk for choking, such as talking or laughing with the mouth full or eating too fast. Children younger than 5 years are at particularly high risk for choking (Box 4-1). Infants and toddlers explore by putting things in their mouths and can easily choke on them. This is because young children do not have the skills needed to chew these foods thoroughly, so they often try to just swallow them whole.
