Fever/Chills As the body becomes weaker, so does If a fever develops let your hospice nurse the temperature control mechanism in know. Often placing a cool wash cloth on the brain; this can cause the person to the forehead and removing blankets may have a fever or cause the body to become be all that is needed. If the person is cool and becomes restless, removing blankets may decrease the restlessness. Disorientation Your loved one may seem confused about Identify yourself by name rather than the time, place and/or identity of people asking the person to guess your name. Often the care required is too much to manage alone; consider how to incorporate the help of friends and family and/or hire professional caregiving help.

The following excerpt provides vignettes illustrating some of the various cues your loved may give as they approach the final stages of life. Instead, if we listen carefully and gently, we may be able to understand what the dying are struggling to tell. By helping to interpret these hidden messages, we can ease the anxiety of patients and family members, and help them find a special closeness. Here is how a hospice nurse drew out such a patient: Laura, 81, was cared for at home by her husband, Joe. She was particularly concerned about leaving him because he relied heavily on her. During a visit 2 weeks before Laura died, the nurse noticed that she seemed distant, withdrawn. He wept but took comfort in the realization that Laura was looking forward to being with Susan again. It is obvious from the conversation that Laura, like so many dying patients, was caught up in the struggle of whether to stay or go. Preparing to Travel, Change As we saw with Laura, the theme of travel is a familiar one with the dying. In an attempt to reorient him, they moved in all of his things from his own room and even hung a map of the town on his wall. We suggested to his parents that he might be trying to find his way to his new home. They felt we were right and, fighting their grief, reassured him that he would find his way soon, that they were ready for him to leave them. Thus, one of our roles is to help them explore what it was like (if they want to) and to offer reassurance if necessary. Choosing When to Die Most of us are aware that the dying often seem to cling to life until a loved one arrives. The hospice nurse assured Jean that she would help to coordinate additional support to be with her. Ask questions and offer sensitively probing insights that might encourage that they say a little more. The Family It is often easier for family members to grasp what the patient says, to understand the possible symbolism and references, because of their knowledge of his/her life-style, experiences, values, and usual way of talking. If he/she resides in a residential facility, please check with a facility representative to ensure EvergreenHealth Hospice is notified. He/she will facilitate a visit by a Hospice representative to provide support (such as help with answering your questions and, if you wish, help with bathing and dressing your loved one in the way you would find meaningful before they leave your/their home for the last time). It may take at least one to two hours for the funeral home to arrive, but you can arrange with the funeral home for more time if you like. When the funeral home representative arrives, he/she will talk with you about the process for transporting the body and answer any questions. You may choose to be present or not when the representative transfers the body to a stretcher and places it in the legally-required bag which encloses the body. The funeral home representative is there to provide respectful care of the body and assist with your concerns. It can be very difficult to transition from the intensity of caregiving to the numbness and sometimes disbelief you may feel as a consequence of the death. Make an appointment to meet with the funeral home director to discuss and confirm all arrangements. You may find that planning and experiencing a memorial service or celebration of life is one of the most meaningful steps you can take within your grieving process. Funeral directors are experienced professionals in helping you create a meaningful memorial service to honor and remember your loved one. Death certificates are created and processed by the funeral home with the information you provide. The funeral home director obtains the signature of the attending doctor to complete and register the death certificate at the appropriate county courthouse. The funeral home director will need to know how many certified copies of the death certificate you need; one rule of thumb is to order one certified copy for each financial institution where your loved one has an account. Some institutions may accept a copy of the certified copy, but most require an original certified copy. Funeral homes can also help with posting an obituary in a local newspaper; costs vary per newspaper. Consider delegating tasks to trusted friends and/or family members to help, knowing that: Calls to financial institutions do not have to be made immediately nor all at once. However, you should also contact Social Security within a reasonable timeframe to see if you qualify for the small death benefit they offer. Your funeral director can provide additional information and coordinate this upon request. The deceased may have left a letter of instructions and/or a Last Will and Testament. An executor will be named within the Will who is responsible for coordinating how the estate is settled. The cost can be fairly minimal compared to the stress involved trying to navigate the legal steps on your own. There may be financial arrangements already made for paying for the funeral and/or burial such as a life insurance policy. While each person experiences grief differently, you may find comfort knowing that others share similar loss responses. Path to Healing Each person has an individual style of coping with painful experiences.

General Recommendations Regarding Glove Use Among Healthcare Workers In general impotence causes purchase super cialis 80mg on-line, healthcare workers should follow precautions to protect themselves at work most effective erectile dysfunction pills generic 80mg super cialis. If latex gloves need to be worn for barrier protection when handling hazardous materials impotence and alcohol 80mg super cialis with amex, healthcare workers should opt for low-protein erectile dysfunction queensland buy super cialis 80 mg on line, powder-free gloves homemade erectile dysfunction pump buy discount super cialis 80 mg online. Special care should be exercised when putting on or removing gloves (especially avoiding letting the gloves snap) erectile dysfunction doctor manila effective super cialis 80 mg, as latex proteins can be diffused into the air. Using glove liners and wearing double and triple gloves can also help reduce exposure to latex. Patients who are diagnosed with latex allergy and their family members should be educated about how to manage this condition and follow preventive measures to avoid future exposure. Healthcare workers should also be encouraged to seek guidance from their employer if they experience latex allergy symptoms.

Approval: 1983 corticosteroids, use over a large surface area or to areas under occlusion, prolonged use, altered skin barrier, liver failure, and use in pediatric patients. Avoid use on the face, groin, or axillae, or if skin atrophy is present at the treatment site. The results suggested that the drug lowered adrenal corticosteroid secretion, although plasma cortisol levels did not go below the lower limit of the normal range. The proportion of subjects with adrenal suppression in this trial was progressively greater, the younger the age group. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. These events are rare and generally occur after prolonged exposure to excessively large doses, especially of high potency topical corticosteroids. Pediatric patients may be more susceptible to systemic toxicity due to their larger skin surface to body mass ratios [see Use in Specific Populations (8. Advise patients to report any visual symptoms and consider referral to an ophthalmologist for evaluation. Such an observation should be corroborated with appropriate diagnostic patch testing. If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. Reported reactions included signs of skin atrophy (telangiectasia, bruising, shininess). Postmarketing reports for local adverse reactions to topical corticosteroids may also include: burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, hypertrichosis, skin atrophy, striae, and miliaria. Hypersensitivity reactions, consisting of predominantly skin signs and symptoms. Ophthalmic adverse reactions of cataracts, glaucoma, increased intraocular pressure, and central serous chorioretinopathy have been reported with the use of topical corticosteroids, including topical betamethasone products. Observational studies suggest an increased risk of low birthweight infants with the use of greater than 300 grams of potent or very potent topical corticosteroid during a pregnancy. In animal reproduction studies, increased malformations, including umbilical hernias, cephalocele, and cleft palate, were observed after intramuscular administration of betamethasone dipropionate to pregnant rabbits. Data Animal Data 3 Betamethasone dipropionate has been shown to cause malformations in rabbits when given by the intramuscular route at doses of 0. The abnormalities observed included umbilical hernias, cephalocele, and cleft palate. It is possible that topical administration of large amounts of betamethasone dipropionate could result in sufficient systemic absorption to produce detectable quantities in human milk. In 19 of 60 (32%) evaluable subjects, adrenal suppression was indicated by either a 5 mcg/dL pre-stimulation cortisol, or a cosyntropin post-stimulation cortisol 18 mcg/dL and/or an increase of <7 mcg/dL from the baseline cortisol. Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of systemic toxicity when treated with topical drugs. Local adverse reactions including skin atrophy have also been reported with use of topical corticosteroids in pediatric patients. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. Betamethasone, an analog of prednisolone, has a high degree of corticosteroid activity and a slight degree of mineralocorticoid activity. However, similar blanching scores do not necessarily imply therapeutic equivalence. The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Inflammation and/or other disease processes in the skin may increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids [see Dosage and Administration (2)]. Once absorbed through the skin, topical corticosteroids enter pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees, are metabolized primarily in the liver, and excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. It was positive in the in vitro human lymphocyte chromosome aberration assay, and equivocal in the in vivo mouse bone marrow micronucleus assay. Studies in rabbits, mice, and rats using intramuscular doses up to 1, 33, and 2 mg/kg, respectively, resulted in dose-related increases in fetal resorptions in rabbits and mice. Inform patients of the following: Discontinue therapy when control is achieved, unless directed otherwise by the physician. Gloving material and techniques have advanced considerably since then, especially in recent years as knowledge of how to maximize safety for patients and health professionals has advanced. This article summarizes recent surgical glove innovations, relevant research and current best practices for surgical gloving. It further discusses trade-ofs and concerns common in operating rooms transitioning from older gloving practices to newer, safer ones. Best Practice Trend #1: Synthetic gloves Reports of latex allergies attracted attention in the the use of latex surgical gloves is on the 1980s. Touching latex or inhaling particles shed from sales has been accelerated, in part, by gloves can cause a reaction. Sensitivity increases over technological improvements to make time and with repeated use. This makes health care synthetic gloves more closely mimic the ft, No treatment exists professionals vulnerable. Undergloves 25 Operating rooms are the hospital are an average of 15 percent thinner than room personnel. Follow-up to percutaneous injury is time to awareness from 67 seconds to 42 expensive: about $600 without prophylactic seconds. Approved moisturizers, when other factors are dermatitis, a non-immunologic response rehydrating products and glove liners the more likely cause of to an irritant or skin damage. The use of jewelry, fragrances, 39 workers often blame synthetic gloves detergents and other products more skin irritation. Seasonal weather changes, non-accelerant gloves should be done frequent hand-washing and wearing if it is determined that the accelerant jewelry contribute to susceptibility to non causes an immune response. The source of hypersensitivity can be elusive because more than 4,000 chemicals are known to have the potential to trigger allergic reactions. Latex can cause potentially severe allergic reactions in health care workers and patients. Using two surgical gloves dramatically reduces the risk of bloodborne infections to health care professionals.

Since it is a constituent part of thimerosal, which is used as a preservative in killed vaccines, concern has been raised with regard to its role in immune-mediated diseases and autism (Clarkson, 2002). This compound has caused illness and several deaths due to erroneous handling when used as a disinfectant or as a preservative in medical prepar ations. The authors also reported that the discontinuation of thimerosal-containing vaccines in Denmark in 1992 was followed by an increase in the incidence of autism. In contrast, epidemio logical evidence, based upon tens of millions of doses of vaccine administered in the United States, that associates increasing thimerosal from vaccines with neurodevelopmental disorders was reported by Geier & Geier (2003). An analysis of the Vaccine Adverse Events Reporting System database showed statistical increases in the incidence rate of autism, mental retardation, and speech disorders with the use of thimerosal-containing diphtheria, tetanus, and acellular pertussis vaccines in comparison with thimerosal-free vaccines. It is a poor inducer of cell-mediated immunity, and there is no epidemiological evidence of it leading to autoimmunity. Recently, some concern has been raised in France in patients where aluminium hydroxide induced persistent macrophagic myofasciitis is present. It has been hypothesized that the persistence of this lesion may be associated with a higher incidence of a syndrome with arthralgias, myalgias, and chronic fatigue (Gherardi et al. This is a broad area that includes caloric intake, specific nutrients and foods, and dietary supplements. The role of iodine in autoimmune thyroid diseases is discussed in chapter 8 (section 8. The following summary of dietary factors focuses on experimental studies using animal models and human studies of the etiology and progression of multiple sclerosis, diabetes mellitus type 1, inflammatory bowel diseases, rheumatoid arthritis, and lupus. The basis for much of this research is the general immunomodulating effect of dietary components, particularly with respect to cytokine production and inflammation. In general, data from studies in humans are more limited and less consistent than the data from animal studies. Fasting can improve symp toms in some patients with rheumatoid arthritis (possibly through an anti-inflammatory effect of fasting mediated through leptin), but the effects are not sustained when the fasting period is over (Muller et al. In mouse models of multiple sclerosis (experimental autoimmune encephalomyelitis) and diabetes mellitus type 1, leptin secretion was closely linked to disease onset (Matarese et al. Recent studies report an effect of leptin on T cell stimulation and production of proinflammatory cytokines (Sanchez-Margalet et al. Caloric restriction in lupus mouse models inhibits the disease process and prolongs survival (Leiba et al. The fatty acid composition of foods is determined by the length of the carbon chain and the number and location of double bonds. The essential fatty acids are those that cannot be synthesized and so are available only from foods or supplements. The relative balance of different prostaglandins and leukotrienes affects the inflammatory response. Because of the potential effects on inflammation and immune mediated function, there has been considerable interest in the potential therapeutic role of omega-3 fatty acids in autoimmune disease. The randomized clinical trials tend to be relatively small, but there is some evidence of improvement in terms of reduced joint count and morning stiffness in trials of fish oil supplementation (Fortin et al. There have also been some small trials (n < 30) of omega-3 supplementation in patients with systemic lupus erythematosus, but these studies were conducted before the adoption of standardized measures of disease activity and damage. In general, some improvements in lipid profiles and inflammatory measures have been seen, but there are mixed results with respect to improvements in clinical status (Leiba et al. In a large observational (non-randomized) study in Japan, there was no association between intake of total fat, type of fat, or omega-3 fatty acids and subsequent disease activity among 216 lupus patients (Minami et al. In ulcerative colitis and Crohn disease, trials of omega-3 (fish oil) supplements have reported improvements in terms of decreased steroid dosage, decreased disease activity, pro longed periods of remission, and increased weight gain, but there are inconsistencies between observed effects among studies, and long term benefits have been difficult to demonstrate (Belluzzi, 2002). Relatively few studies have been conducted examining fats and fatty acid intake in relation to risk of developing specific auto immune diseases. In a recent analysis of risk of multiple sclerosis in two large cohorts of women, no association was seen with total fat, monounsaturated fat, or total n-6 or total n-3 polyunsaturated fats (Zhang et al. There is some evidence that damage induced by reactive oxygen species contributes to the destruction of pancreatic beta cells, brain tissue, and joints seen in diabetes mellitus type 1, mul tiple sclerosis, and rheumatoid arthritis, respectively. However, there are few prospective studies of antioxidant intake and risk of auto immune diseases. Although there is some evidence of a reduced risk of rheumatoid arthritis and lupus with higher intake or serum levels of antioxidants, there are inconsistent findings with respect to which antioxidants or foods are involved (Comstock et al. Only one prospective study of antioxidants and risk of multiple sclerosis is available, and that study reported no association with intakes of vitamin C, vitamin E, or carotenoids (Zhang et al. Hydroxylation of this compound in the liver produces 25-hydroxycholecalciferol, which is then converted in the kidney to 1,25-hydroxychole calciferol, the active form of vitamin D. Vitamin D plays a major role in promoting absorption of calcium and maintaining bone mineralization. The vitamin D receptor has been detected in lymphocytes and the thymus, and vitamin D plays a role in T cell-mediated immune response (Deluca & Cantorna, 2001). Most of the human studies of vitamin D and autoimmune diseases have focused on diabetes mellitus type 1 and multiple sclerosis. Prospective studies have also reported a reduced risk of multiple sclerosis (Munger et al. The relative contribution of foods and supplements to the protective effects seen in these studies is not clear. In murine models of experimental autoimmune encephalo myelitis (multiple sclerosis), diabetes mellitus type 1, and inflamma tory bowel disease, treatment with 1,25-hydroxycholecalciferol (in conjunction with adequate calcium intake) has been shown to inhibit the development of disease (Froicu et al. In lupus mouse strains, however, a more complex situation is seen, with some evidence of worsening of disease (particularly with respect to measures of renal damage) with 1,25-hydroxycholecalciferol treatment (Vaisberg et al. An essential amino acid and serotonin precursor, L-tryptophan is used to treat depression, premenstrual syndrome, and insomnia. In nine months, 1658 people were diagnosed with the disease in the United States, Germany, and Belgium (Swygert et al. A product recall dramatically reduced the number of new cases reported, although approximately 3% of patients with eosinophilia myalgia syndrome did not use L tryptophan (Swygert et al. Although eosino philia myalgia syndrome was most frequently reported in women (84%), non-Hispanic whites (97%), and residents of western states in the United States (Swygert et al. There have been associations with dose, age of the patient (average 48 years), and a single supplier that had made changes in the manufacturing process preceding the epidemic (Swygert et al. The hallmark manifestations of eosinophilia 3 myalgia syndrome are profound eosinophilia (>1000 cells/mm) and debilitating myalgia (Swygert et al. Muscle and fascia from patients with eosinophilia myalgia syndrome revealed an inflamma tory exudate composed primarily of activated T cells and macro phages at perimysial, endomysial, perivascular, and fascial sites. The true etiologic agent of eosinophilia myalgia syndrome and the mechanism of action remain elusive; however, the prevailing theories support a combination of genetic susceptibility, haptenation of self-proteins by L-tryptophan contaminants and subsequent activation of auto reactive T cells, and a cell-mediated immune response targeting connective tissue. It is important to point out that the nutritional and microbial status of the animals can influence the outcome of the autoimmune diseases (see also chapter 9). Etiology in the various models can be based either on spon taneous, genetically predisposed development or on induction with specific antigens (mostly in combination with an adjuvant), infec tious agents, or chemicals (Chernajovsky et al. Irrespectively of how the disease is induced, most models rely on inbred animals, indicating the importance of genetic back ground and in accordance with the idiosyncratic nature of many autoimmune diseases. In the case of spontaneous autoimmune diseases, mice are most frequently used; with the advent of genetically modified mice, the number of genetically predisposed autoimmune models has increased enormously. For systemic lupus erythematosus, about 30 genetically modified mouse models have been described (Chan et al. New models have been designed using transgenics or gene invalidation techniques for type 1 (insulin-dependent) diabetes, multiple sclerosis, and arthritis (Goverman, 1999; Holmdahl et al. Based on the multifactorial and idiosyncratic nature of autoimmune diseases, it is not surprising that relatively few compounds have been shown to induce clinically apparent 178 Animal Models to Assess Chemical-Induced Autoimmunity autoimmune or autoimmune-like allergic phenomena in animals. The route of exposure may be of significance in relation to interpretation and extrapolation of data from animal models to the development and status of human autoimmune diseases. However, it is important to note that routes of exposure used in many animal models. The autoimmune-related effects that have been observed in the Brown Norway rat model are only partly compound specific and include both local (glomerulonephritis, splenomegaly, skin rashes, inflammatory responses in lungs) and systemic effects (hyper immunoglobulinaemia, in particular IgE, and increased levels of autoantibodies). Derangements in Brown Norway rats are accom panied by polyclonal lymphoproliferation (both T and B cells) 180 Animal Models to Assess Chemical-Induced Autoimmunity (Hirsch et al. This property and/or the underlying genetic trait may be responsible for the high susceptibility of this strain to chemical induced autoimmune effects. However, as for disease-prone mouse strains, it can also be argued that the inherent susceptibility of this rat strain resembles the inherent susceptibility in human cases of chemical-induced autoimmune disorders. After 20 days, immune alterations are mostly at control level, and the kidney effects. These phenomena, transience of autoimmune effects as well as low-dose protection, are shown to be due at least in part to the development of regulatory immune cells. Recently, a series of studies have further explored D-penicillamine-induced autoim munity in the Brown Norway rat, in particular with respect to immunoregulation (Masson & Uetrecht, 2004). It appeared that the observed tolerance is mediated by immune cells, including T and non-T cells. This again illustrates that idiosyncracy also occurs in animals and moreover that these diseases are subject to regulatory mechanisms. All of these rat strains displayed hexachlorobenzene-induced symptoms reminiscent of an autoimmune-like disease (splenomegaly, increased serum levels of autoantibodies, inflammatory responses in lungs and skin), with the Brown Norway rat the most sensitive (Michielsen et al. This strain independence indicates that hexachloroben zene-induced pathology is probably less or not at all idiosyncratic. In addition, a clear role of T cells has not been found, although interference with T cell activation by cyclosporin prevented or delayed a number of T cell-dependent responses, such as levels of IgE and eosinophilia in the lung, and skin lesions (Ezendam et al. It is currently thought that hexachlorobenzene is probably a general inflammatory rather than an autoimmunogenic chemical (Ezendam et al. About two weeks after cessation of cyclosporin treatment, which starts on the day of the bone marrow transplantation, the rats start to develop autoimmune disease. Acute symptoms of cyclosporin-induced autoimmunity are similar to those of graft versus host disease, with erythroderma, dermatitis, and alopecia. The chronic phase is characterized by progressive alopecia combined with scleroderma-like skin pathology. This probably is the cause of the increased release of autoreactive T cells (Kosugi et al. In line with this and with the protocol required to induce cyclosporin-induced autoimmunity in rat, neonatal administration of cyclosporin in mice also induces a multiorgan-type autoimmune disease (Sakaguchi & Sakaguchi, 1989). Other H2s mice, such as B10s mice, are also susceptible, but congenic H2d mice. The antineoplastic drug streptozotocin is capable of inducing type 1 (insulin-dependent) diabetes when administered (intraper itoneally) at low doses on six consecutive days. Procainamide has been found to induce an increase in anti nuclear antibodies in A/J mice after eight months of exposure via the drinking-water (Layland et al. The disease is accompanied by a broad spectrum of autoantibodies (rheumatoid factor, anticollagen, antibodies to heat shock protein). Pristane-induced arthritis is clearly immune dependent, since it is not observed in nu/nu mice and + irradiated mice (Wooley & Whalen, 1991). It is controlled by multiple genes, identified as pristane-induced arthritis (pia) loci (Olofsson et al. The rationale behind using autoimmune-prone animal strains for the purpose of studying and predicting the autoim munogenic potential of chemicals is that, apart from being probably very sensitive for adverse immune effects, exacerbation of disease is considered one of the possibilities by which chemicals may elicit autoimmune phenomena (Pollard et al. As mentioned also, the Brown Norway rat is a sensitive rat strain for Th2-dependent phenomena, as is the Lewis rat for cyclosporin-induced autoim munity. In induced models, a susceptible animal strain is immunized with a mixture of an adjuvant and an autoantigen isolated from the target organ. Examples are adjuvant arthritis in the Lewis strain rat (Pearson, 1956) and experimental allergic encephalomyelitis, a model of multiple sclerosis (Ben-Nun & Cohen, 1982). Induced models are often used to study the pathogenesis of and therapeutic venues for relevant autoimmune diseases. These models have been proposed as means to evaluate the immunomodulatory effects of chemicals on ongoing autoimmune diseases in a second tier of immunotoxicity testing. Although drug-induced lupus differs from systemic lupus erythematosus in certain aspects (Pollard et al.
