In an analysis of 146 patients with mild asthma who had undergone bronchial provocation challenge with histamine buy motilium on line, two patterns were identified ( 106) buy motilium 10 mg on line. It was concluded that the latter subjects experienced excessive bronchoconstriction (106) discount generic motilium canada. Hypersecretion of bronchial mucus may be limited or extensive in patients with asthma. Autopsy studies of patients who died from asthma after having symptoms for days or weeks classically reveal extensive mucus plugging of airways. Large and small airways are filled with viscid mucus that is so thick that the plugs must be cut for examination (107). Reid (107) has described this pattern as consistent with endobronchial mucus suffocation. A virtual absence of mucus plugging, called empty airways or sudden asphyxic asthma, has been reported (107,108). Desquamation of bronchial epithelium can be identified on histologic examination ( 109) or when a patient coughs up clumps of desquamated epithelial cells (creola bodies). Bronchial mucus contains eosinophils, which may be observed in expectorated sputum. Charcot-Leyden crystals (lysophospholipase) are derived from eosinophils and appear as dipyramidal hexagons or needles in sputum. Viscid mucus plugs, when expectorated, can form a cast of the bronchi and are called Curschmann spirals. Clinically, mucus hypersecretion is reduced or eliminated after treatment of acute asthma or inadequately controlled chronic asthma with systemic and then inhaled corticosteroids. Mucus from patients with asthma has tightly bound glycoprotein and lipid, compared with mucus from patients with chronic bronchitis ( 110). Macrophages have been shown to produce a mucus secretagogue as well as generate mediators and cytokines ( 98,111). Because plasma cell staining for IgE was not increased in number, it has been thought that IgE is not produced locally. However, because the lung is recognized as an immunologic organ, further work may that show IgE is produced in the lung. The mechanism of bronchial hyperresponsiveness in asthma is unknown but is perhaps the central abnormality physiologically. However, bronchial hyperresponsiveness is not specific for asthma because it occurs in other patients without asthma ( Table 22. Nevertheless, hyperresponsiveness consists of bronchoconstriction, hypersecretion, and hyperemia (mucosa edema). The bronchial responsiveness detected after challenge with histamine or methacholine measures bronchial sensitivity or ease of bronchoconstriction ( 106). As stated, an additional finding in some patients with asthma is excessive bronchoconstriction, which can be attributable to associated increases in residual volume and possibly more rapid clinical deterioration ( 106). Often, on opening the thorax of a patient who has died from status asthmaticus, the lungs are hyperinflated and do not collapse ( Fig. In some cases, complicating factors, such as atelectasis or acute pneumonia, are identified. Upon histologic examination, there is a patchy loss of bronchial epithelium with desquamation and denudation of mucosal epithelium. Other histologic findings include hyperplasia of bronchial mucus glands, bronchial mucosal edema, smooth muscle hypertrophy, and basement membrane thickening (Fig. Occasionally, bronchial epithelium is denuded, but histologic studies do not identify eosinophils. Similarly, although many autopsy examinations reveal the classic pattern of mucus plugging ( Fig. Eosinophils have been identified in such cases in airways or in basement membranes, but a gross mechanical explanation, analogous to mucus suffocation, is not present. A third morphologic pattern of patients dying from asthma is that of mild to moderate mucus plugging (107). Some patients dying from asthma have evidence of myocardial contraction band necrosis, which is different from myocardial necrosis associated with infarction. Contraction bands are present in necrotic myocardial smooth muscle cell bands in asthma and curiously the cells are thought to die in tetanic contraction whereas in cases of fatal myocardial infarction, cells die in relaxation. Pleural pressure becomes more negative, so that as inspiration occurs, the patient is able to apply sufficient radial traction on the airways to maintain their potency. Air can get in more easily than it can be expired, which results in progressively breathing at higher and higher lung volumes. The residual volume increases several-fold, and functional residual capacity expands as well. The lung hyperinflation is not distributed evenly, and some areas of the lung have a high or low ventilation-perfusion ratio ( / ). Overall, the hypoxemia that results from status asthmatics occurs from reduced /, not from shunting of blood. The lung hyperinflation also results in dynamic autopeep as the patient attempts to maintain airway caliber by applying some endogenous positive airway pressure. There is no evidence of chest wall (inspiratory muscle) weakness in patients with asthma. Nevertheless, some patients who have received prolonged courses of daily or twice-daily prednisone or who have been mechanically ventilated with muscle relaxants and corticosteroids can be those who have respiratory muscle fatigue. After successful treatment of an attack of status asthmaticus, the increases in lung volume may remain present for 6 weeks. Small airways may remain obstructed for weeks or months; in some patients, they do not become normal again. At the same time, it can be expected that the patient has no sensation of dyspnea within 1 week of treatment of status asthmaticus despite increases in residual volume and reduced small airways caliber. This divergence between symptom recognition in asthma and physiologic measurements has been demonstrated in ambulatory patients who did not have status asthmaticus (114). The reduction in trapped gas in the lung can result in symptom reduction even without improvement in expiratory flow rates.

Great Lakes Theater and the Baldwin Wallace University s Department of Theater and Dance have collaborated with the Cleveland Clinic and University Hospitals to offer educational workshops in 2012 for internal medicine residents, helping them develop better relationships with their patients and engage with diverse populations. Doctors as Artists As arts and culture activities play an increasingly signifcant role in medical education, it is not uncommon for practicing doctors to identify as artists themselves in one or both of two ways. In the second way, some doctors view themselves literally as artists, reporting their direct engagement in artistic and creative practices for myriad purposes ranging from the examination of personal emotions that arise from their practice of medicine to the use of arts activities to Community Partnership for Arts and Culture 57 Creative Minds in Medicine Medical Training and Medical Humanities relieve stress and distract from job-related pressures. Those specializing in performance arts medicine focus on treating the specifc needs of actors, dancers and musicians. Locally, the Cleveland Clinic s Medical Center for Performing Artists treats voice, hearing and neuromuscular disorders common in performing artists. In numerous ways, the skills of arts and culture are informing the practice of medicine and arts and culture organizations are increasingly serving as resources for the medical community. Community Partnership for Arts and Culture 58 Creative Minds in Medicine case study devising healthy communities Katherine Burke leading a session at Rainey Institute Photo courtesy of Katherine Burke Community Partnership for Arts and Culture 59 Creative Minds in Medicine humanizing medical training For a little while during his 2011-12 academic year, medical student Vincent Cruz stopped reading textbooks and played with clay, instead. Cruz and a classmate were fnding out how making art with clay helps brain-injured patients get better. The pair had already sat in on a number of sessions with the Art Therapy Studio s Traumatic Brain Injury clay-studio group, observing the amazing ability of the human brain to rewire - how the physical act of working with clay (using hand- eye coordination and motor skills) helped promote this process, he writes in a recent e-mail. He believes that being a doctor means more than being a fact-driven scientist; it is important for medical professionals to understand not only their patients humanity, but also their own. Kohn long ago recognized that the arts can be one of the keys to the personal meaning often locked away in the name of objectivity. To help data-swamped future doctors get in touch with the creative, cultural and emotional sides of human beings and recognize that those areas directly affect health, Kohn devised an arts-based qualitative-research experience for frst-year med students in collaboration with Katherine Burke, an adjunct member of Kent State University s theater faculty. The idea is to give students opportunities to observe artists working with patients and other members of the community and see the effects of arts activity on people as well as the communities in which they live. They develop research and reporting skills in the process, write personal refections and, at program s end, relate the story of that community-arts experience to others. It also helps students fnd their own voices, express their own feelings and share their own stories with the people around them, Burke explains: The way in which one tells a story has a way of forming an identity for both the storyteller and the community listening to him or her. As Cruz writes, observing the clay studio was an important exercise to see how art in the community much like nursing homes, outpatient offces and rehab facilities is integral to the well-being The Medical and recovery of patients weeks/months/years after leaving the hospital, since this is often Humanities diffcult to appreciate when we are so focused on the immediate tasks of in-patient medicine. Kohn s commitment to helping members of mundane and medical communities express themselves profound of their goes back to his early years at Northeast Ohio Medical University, where he founded an chosen profession. But it wasn t until he had co-founded and begun co-directing the Center for Literature in Medicine at Northeast Ohio s Hiram College that he had a real epiphany about arts and medicine. He had started collaborating with the then-named Great Lakes Theater Festival, working with theater artists on a narrative bioethics program and It just opened up my world, he said. In this way, his Medical Humanities program has sought to help students refect on their identity, their role in society and larger cultural patterns as they face the issues mundane and profound of their chosen profession. Kohn s approach helps turn a young doctor like Bryan Sisk into a different type of physician: one who is not only a scientist, but a human being, as well. He found that the group writing exercises, thought-provoking speakers and the wide range of arts and media that made up his training in humanities at Lerner have given him the ability to cope better with his patients feelings and his own. The following best practices are important considerations when developing and implementing programs that bring together the arts and culture and the health and human services sectors: Understanding context. Before embarking on an arts and health program, it is essential for all parties involved to develop a solid understanding of what populations will be served, what their specifc needs are and what available resources exist for implementing the program. It is essential that arts and culture practitioners recognize the unique strengths, challenges and backgrounds of each participant, as well as the resources and limitations of each healthcare setting. Funding arts and health programs can be challenging in light of lower levels of available philanthropic support, limitations on what types of activities are covered by insurance, and rising healthcare costs. The formation of strategic alliances can help broaden the base of philanthropic support, while research can provide evidence that documents the medical costs savings and other benefts associated with such interventions. In order to achieve full integration of, and participation in, arts and health activities, it is important to consider barriers to access. For example, artists who are not trained expressive arts therapists may not know how to get involved in healthcare facilities, healthcare providers might have preconceived ideas about the nature of arts and culture activities and patients may think they are not skilled enough to participate. Additionally, practical barriers may include diffculty traveling to arts and health programs, lack of funding for programs and inadequate space to carry out programs. Collaborations can yield numerous benefts such as the sharing of expertise, access to resources and greater effciency and effectiveness of service delivery. When the arts and health felds intersect, partnership offers a way to further humanize healthcare settings and empower patients to share their stories and interact with others in different ways. As with any collaboration, success is achievable only when the parties involved communicate regularly, set clear and measurable goals and delineate expectations. Populations being served should also be given opportunities to share their experiences and talk about what best meets their needs. The collection and dissemination of verifable, high-quality data are essential to bolstering the case for continued integration of the arts and culture and health and human services sectors. The most powerful accounts meld quantitative data into a patient s personal journey. In this way, the patient s story humanizes the numbers in data tables, while the data tables can lend verifability to the intrinsic values of arts and culture experience. Community Partnership for Arts and Culture 63 Creative Minds in Medicine Educating the public, healthcare professionals and artists about the intersection. In order to foster and strengthen the intersection between arts and health, it is essential for arts and health stakeholders to be given opportunities to share their experiences and educate others about the different ways arts and health intersect. Since the intersection runs along a continuum that varies according to factors such as engagement, programmatic structure and goals, it is important to think about arts and health defnitions broadly to invite new avenues for participation. When introducing arts and culture into healthcare settings, strategies to ensure the maintenance of sterile environments are essential to protecting the safety of patients. For artists, gaining a shared understanding with healthcare providers during the development of arts and health projects can allow them to customize programming to meet the special needs of patients and understand how to best engage them in arts and culture activities.

Until now, Life Extension could cite only isolated statistics to make its case about the dangers of conventional medicine. A group of researchers meticulously reviewed the statistical evidence and their findings are absolutely shocking. This fully referenced report shows the number of people having in-hospital, adverse reactions to prescribed drugs to be 2. The number of unnecessary antibiotics prescribed annually for viral infections is 20 million per year. The number of unnecessary medical and surgical procedures performed annually is 7. The most stunning statistic, however, is that the total number of deaths caused by conventional medicine is an astounding 783,936 per year. The article uncovered so many problems with conventional medicine however, that it became too long to fit within these pages. We placed this article on our website to memorialize the failure of the American medical system. By exposing these gruesome statistics in painstaking detail, we provide a basis for competent and compassionate medical professionals to recognize the inadequacies of today s system and at least attempt to institute meaningful reforms. Natural medicine is under siege, as pharmaceutical company lobbyists urge lawmakers to deprive Americans of the benefits of dietary supplements. Drug-company front groups have launched slanderous media campaigns to discredit the value of healthy lifestyles. These attacks against natural medicine obscure a lethal problem that until now was buried in thousands of pages of scientific text. In response to these baseless challenges to natural medicine, the Nutrition Institute of America commissioned an independent review of the quality of government-approved medicine. The startling findings from this meticulous study indicate that conventional medicine is the leading cause of death in the United States. The Nutrition Institute of America is a nonprofit organization that has sponsored independent research for the past 30 years.

Reflux of gastric acid into the lower esophagus can precipitate symptoms of asthma or cough without frank aspiration purchase line motilium, perhaps by an esophagobronchial vagal reflex ( 206) order 10mg motilium amex. An acute episode of asthma can cause increased negative intrathoracic pressures, which can increase reflux. Surgical intervention is indicated rarely but has been successful in varying degrees with either laparoscopic fundoplication or open procedures in patients with large hiatal hernias or strictures or previous surgery (206). Left-sided congestive heart failure has been associated with exacerbations of asthma. Bronchial hyperresponsiveness has been recognized in nonasthmatic patients who developed left ventricular failure. When patients with asthma develop congestive heart failure, at times, sudden episodes of wheezing dyspnea can occur in the absence of neck vein distention or peripheral edema, which would support a diagnosis of left ventricular failure. Similarly, long-term treatment regimens depend on the type of asthma and its severity. The basic objective of treatment, as in other chronic illnesses, is to achieve significant control of symptoms to prevent physical as well as psychological impairment. The goals should be to maximize control of symptoms of asthma, permit as normal a lifestyle as possible, avoid nocturnal asthma, and achieve as best respiratory status as possible. Principles The treatment of asthma consists of therapeutic measures to control inflammatory changes and to reverse bronchial mucosal edema, bronchospasm, hypersecretion of mucus, and / imbalance. Depending on the severity of the attack, various degrees of hypocarbia or hypercarbia with their resultant acid-base changes may also require specific therapy. Finally, other emergency measures may be necessary to prevent or treat acute respiratory failure. In allergic asthma, removing the offending allergen or allergens is of primary importance because it can reduce symptoms, decrease the need for medication, and eventually decrease bronchial hyperresponsiveness. Protective measures must also be included to lessen the deleterious effects of certain aggravating factors, such as dust mites and fungi. The best approach to asthma treatment consists of determining the clinical classification ( Table 22. Chronic asthma tips Drug Therapy b-Adrenergic Receptor Antagonists The effects of an adrenergic agonist depend on its specific (a or b) receptor-stimulating capacity as well as on the type and density of receptor present in the organ or tissue stimulated (Table 22. The bronchi contain predominantly b2-adrenergic receptors, which promote bronchodilation. Those in the heart are primarily b 1-adrenergic receptors, which increase cardiac contractibility and heart rate. These effects reverse or inhibit some of the pathophysiologic events known to occur in asthma. The regulatory protein G S couples b-adrenergic receptors to adenyl cyclase and calcium channels. For example, as with inhaled corticosteroids and theophylline, the dose-response curve for b2-adrenergic agonists becomes flattened as the dose of medication is increased. In addition, aside from increasing function of cilia in epithelial cells, there seem to be almost no antiinflammatory effects from b 2-adrenergic agonists. The conclusion was that regular, scheduled use of albuterol could cause continued airway inflammation. How much clinical effect these data have on asthma control and management has been controversial. For patients with persistent asthma, however, it has been advisable to use antiinflammatory therapy and a b-adrenergic agonist together, trying not to use additional scheduled short-acting b 2-adrenergic agonists. The combination of an inhaled corticosteroid and 12-hour b2-adrenergic agonist, even scheduled, provides effective asthma control. As patients improve, less b 2-adrenergic agonist can be used, whether short acting or long acting. A medication may be a bronchodilator, and it may or may not have bronchoprotective properties. As regards salmeterol, 24 patients with mild asthma received either salmeterol 50 g twice daily or placebo for 8 weeks ( 211). Thus, although a bronchodilator effect continued, bronchoprotection was temporary and associated with tolerance ( 211). Somewhat similar findings have been reported with terbutaline, 500 g given four times daily ( 212). In a 16-week study of 255 patients with mild asthma, as-needed and scheduled albuterol produced similar degrees of bronchodilation and symptom control ( 213). Patients with moderate or severe persistent asthma may require scheduled salmeterol or formoterol and intermittent albuterol or other short-acting b 2-adrenergic agonist. Such patients should receive antiinflammatory therapy, but even in its absence, in this study, tachyphylaxis to albuterol did not occur ( 214). Physicians (and pharmacists) need to be aware of overuse of metered-dose inhalers, dry-powder inhalers, or nebulizers by patients. Unlimited or unsupervised prescription refills cannot be recommended because patient self-management when asthma is worsening may result in a fatality. As an asthma attack worsens and continued b 2-adrenergic agonist therapy is used in the absence of inhaled or oral corticosteroids, there may be development of arterial hypoxemia, carbon dioxide retention, and acidosis not recognized by the patient. Various alterations of the molecular structure of the catecholamine nucleus have resulted in a variety of antiasthma drugs ( Fig. The chemical structures of sympathomimetic drugs compared with those of phenylethylamine. Epinephrine Epinephrine, administered intramuscularly, because of its potent bronchodilating effect and rapid onset of action, is an alternative therapy but is not recommended for ambulatory use by inhalation in acute asthma. Nebulized racemic epinephrine is also effective but is used less commonly today unless a patient has upper airway obstruction (epiglottitis or stridor). Some side effects of epinephrine include agitation, tremulousness, tachycardia, and palpitation. Hypertension in the presence of acute asthma often resolves with epinephrine administration.
