The epidemic curve indicated secondary transmission arrhythmia diagnosis purchase altace 1.25mg amex, thus confirming mosquitoborne transmission arteria century 21 order altace 5 mg with visa. The principal risk factor for malaria was sleeping on a particular hillside outdoors during the evening. California From 1980 through 1990, 13 outbreaks of presumed mosquitoborne transmission were reported from California. Most occurred in rural areas where medical services were limited and sanitary facilities and housing were often substandard, New Jersey In 1991, two separate episodes of locally acquired P. The index case-patient was an 8-year-old boy, without risk factors for malaria, (travel or exposure to blood or blood products). Few undocumented agriculture workers were living in this suburban area, but a large number of documented immigrants and undocumented factory workers were identified. Each point denotes the location of the episode, the species identified (V = Plasmodium vivax, F = P. The weather was hotter and more humid than usual, and higher anopheline densities were reported from some regions of New Jersey. The second case-patient had no clear exposure to mosquitoes but may have been exposed during the early evening in a marshy area where he played ball. Results from an indirect immunofluorescence assay for malaria antibodies conducted on serum specimens obtained in August and December provided additional evidence that his illness during the summer was malaria. Environmental investigation identified possible breeding sites, and adult female An. In addition, the average temperature and humidity favored mosquito survival and development. The three outbreaks that occurred in the early 1990s in densely populated areas occurred in neighborhoods with many immigrants from countries with malaria transmission and weather that was hot and humid and, therefore, conducive to the completion of the sporogonic cycle and the survival of adult female anophelines. The delay between mosquito inoculation, diagnosis, and investigation often meant changes in weather and inability to confirm the presence of adult anophelines and active breeding sites. New York City In 1993, another outbreak of locally acquired malaria occurred in New York City (4). The index patient had no travel history or other means of acquiring malaria except local mosquitoborne transmission. The investigation identified two other cases of malaria; one in a person who had traveled internationally 2 years previously, and a third case which was initially unreported. This outbreak was unusual, not only because urban areas are poor habitats for anophelines, but also because the causative parasite was P. The area where the cases were identified in northwest Queens had many immigrants; the 1990 census showed a 31% increase in the number of foreign-born persons, which accounted for 48% of all recent immigrants into Queens. Many of these immigrants were from malaria-endemic areas, including parts of South and Central America and Hispaniola (Dominican Republic and Haiti). As seen with the earlier outbreaks, the weather that summer was hotter and more humid than usual. During the several weeks between the proposed dates of transmission and the investigation, the weather had changed, interfering with the identification of active anopheline breeding sites or adult anophelines. Houston, Texas Three cases of locally acquired malaria were identified in Houston in 1994 (5). This investigation had features similar to those seen in previous outbreaks in California. All three patients were homeless and lived in substandard housing, which provided an opportunity for exposure to anophelines at night. Two of the patients became ill, and malaria was diagnosed in July; the duration of illness was 11 days to 3 weeks. The third patient had symptoms in late July, but a diagnosis of Discussion Understanding the factors that contributed to these outbreaks and improving case surveillance will facilitate detection of future outbreaks and development of appropriate prevention and control measures. Two necessary criteria must be met for malaria transmission: anopheline vectors capable of transmitting malaria and gametocytemic persons. Under current conditions, the average lifespan of anophelines in the United States is less than the duration of the sporogonic cycle. A common feature of all recent outbreaks has been weather that is hotter and more humid than usual, which may increase anopheline survival and decrease the duration of the sporogonic cycle enough to allow for the development of infective sporozoites. The possible effect of weather on malaria transmission has been cited in recent articles on the potential consequences of global environmental changes (31-33). Detection of locally acquired cases depends on accurate diagnosis and reporting of cases. Prompt diagnosis, treatment, and notification are essential for proper treatment and evaluation of potentially gametocytemic persons. Alternative hypotheses for explaining malaria infection acquired in areas without ongoing transmission have included importation of infective anophelines either on airplanes, ships, or in baggage (34-36). Like the United States, many parts of Europe, including regions of Germany, have had endemic malaria transmission and thus are at risk for introduced autochthonous transmission. The possibility of "baggage malaria" is intriguing but unlikely for reasons concerning mosquito survival during transport and expected host-seeking behavior once the mosquitoes are released from luggage. Water management, improved housing, and access to health care are critical for preventing transmission. Diligent malaria surveillance can detect outbreaks early and allow control measures to interrupt transmission. An outbreak of introduced malaria in California possibly involving secondary transmission. Monica Parise for her efforts in conducting the literature review on locally acquired malaria in the United States, and Dr. Transmission of Plasmodium vivax malaria-San Diego County, California, 1988 and 1989. In July 1994, a physician in Chestertown, Maryland, reported eight cases of Lyme disease to the Kent County Health Department. All 51 surveyed camp employees gave histories of tick exposure throughout the summer. Four other counselors had recurrent fever of 102°F to 104°F, severe headaches, somnolence, malaise, fatigue, myalgia, and anorexia. All four described extensive fatigue, drowsiness, and difficulty in getting out of bed. The camp physician admitted them all to the camp dispensary; Lyme disease was not diagnosed in any of them; only the patient with diarrhea was given an antimicrobial agent, trimethoprim/sulfamethoxazole. Sera were obtained in mid-August from the 51 employees; for the eight patients described above, this was 4 to 7 weeks after the onset of illness. Hard ticks were collected by dragging felt material at several sites within the camp on three occasions during August. Although the infection rate was higher in female ticks collected from the camp, the results cannot be interpreted because the female ticks were cofed on rabbits; it is not certain whether this could cross-infect ticks feeding on the same animals. Also, Kent County has one of the highest incidences of Lyme disease in the state (3), many deer were present in the woods and fields in and around the camp, and all counselors reported frequent exposure to ticks. The four patients who had an acute febrile illness without cutaneous lesions were not initially suspected to have acute Lyme disease. Acutely febrile patients, who have been bitten by a tick in Lyme disease-endemic areas also should be considered for early antibiotic therapy. Doxycycline or another tetracycline is effective for Lyme disease as well as for infections with E. Serologic testing, although it can confirm the diagnosis during the convalescence phase, may not establish an early diagnosis in either case, since antibody responses to all three infections are usually delayed until 2 to 4 weeks after the onset of symptoms and may not occur in patients treated with antibiotics (5-8). We interpreted the Western blots according to criteria proposed at the Second National Meeting on Serological Diagnosis of Lyme disease (6). Many of the counselors had been at the camp during previous summers and could have had prior mild, nondiagnosed infections with B. Patient 13 who had IgM evidence of recent infection on Western blot may have had a mild infection with B. However, this is impossible to confirm without acute-phase and convalescent-phase (or preexposure and postexposure) serum samples. This is also pertinent to those with flulike symptoms and negative Western blot results (patients 6 and 7). The positive predictive value of a diagnostic test is highly dependent on the prevalence of the disease being studied. If the prevalence of Lyme disease in the population screened is very low, the positive predictive value of testing may be too low to be diagnostically useful.

Lyme arthritis: an epidemic of oligoarticular arthritis in children and adults in three Connecticut communities. Recommendations for test performance and interpretation from the Second National Conference on Serologic Diagnosis of Lyme Disease. In each instance, the disease was recognized through investigation of illness for which no cause had been identified. Retrospective studies of these and other newly recognized infectious diseases often identified cases that occurred before the recognition of the new agent; therefore, a more sensitive detection system may make the earlier recognition of new infectious agents possible. Similarly, toxic shock syndrome was recognized in late 1979 and early 1980, but retrospective reporting and chart reviews documented cases as early as 1960 (4). The difficulty of identifying unknown etiologic agents is part of the reason for delays between the occurrence and recognition of new infectious diseases. Until recently, to identify new infectious agents we relied primarily on culture techniques. A more systematic public health approach for the early detection of unknown infectious agents is needed. Some projects are conducted at all program sites and others, depending on local interest and expertise, at only one or two sites. This is the first attempt to conduct surveillance for early detection of new infectious diseases in a large U. The year 1992 was the most recent for which national data were available at the time of this study. Multiple cause-of-death data listed on the National Center for Health Statistics death record allow for analysis of mortality data based on the different causes (15). These deaths accounted for 14% of all deaths (n = 5,304) among persons 1 to 49 years of age in hospitals and emergency rooms. Overall rates among blacks were almost four times as high as those among whites (29. These geographic differences could be accounted for only in part by differences in the proportions of blacks by site. Persons 1 to 24 years of age accounted for only 19% of deaths, while persons 40 to 49 years of age accounted for 50%. In the first, clinicians will be asked to report unexplained deaths and serious illnesses from possibly infectious causes. The first approach allows prospective collection of data and specimens for deaths and serious illnesses. Admitted to a hospital or emergency room with life-threatening illness of potentially infectious etiology 3. Classifying patients as having one or more infectious disease-related syndrome(s) as listed below should help identify groups of patients with similar illnesses for laboratory testing. Conjunctivitis, keratitis, endophthalmitis, or periocular infection and h/o fever 5. Meningitis, encephalitis, encephalopathy, dementia, or other neurologic syndrome with or without a h/o of fever 8. Rash, skin or mucosal membrane lesions, cellulitis, myositis, lymphadenitis, or lymphangitis and h/o of fever 9. Respiratory failure, pulmonary infiltrates, or other pleuropulmonary manifestation and h/o of fever 11. For patients who are still alive or have died recently, clinical and pathology laboratories will be asked to save clinical specimens (including biopsied tissues) obtained during clinical care and diagnostic evaluation. Range of specimens will vary but be appropriate for the given illness and organ systems affected. Deaths will be handled as in the clinician-based system with regard to periodic review and laboratory testing, although it is expected that fewer clinical specimens will be available from patients whose deaths were not reported through the clinician-based system. When a sufficient number of patients with similar illnesses are identified, a customized strategy for laboratory testing will be designed. Serology and immunohistochemistry will be used to narrow the scope of possible etiologies. Clinicians who reported cases will be informed of laboratory results, but information will usually not be available in time to affect treatment of individual patients. Until now, unexplained deaths and serious illnesses due to possibly infectious causes have not been addressed as a specific public health problem. This has been made more feasible by newly developed nucleic acid-based methods for identification of unknown etiologic agents. Another critical limitation is failure to identify deaths that are, in fact, unexplained but have been given an incorrect diagnosis. For several reasons, our surveillance is limited to persons 1 to 49 years of age who have been healthy. The 1-year lower age limit was selected to avoid confusion with congenital problems in infants but include most children in day-care, where infectious diseases are common and a new infectious disease might spread rapidly. The upper age limit was set to exclude an expected increased proportion of unexplained deaths from noninfectious causes in persons 50 years and older.

Hospitals experienced price increases in excess of 80 percent across different classes of drugs, including those for anesthetics, parenteral solutions, opioid agonists, and chemotherapy. Over 90 percent of surveyed hospitals reported having to identify alternative therapies to mitigate the impact of drug price increases and shortages. Hospitals report that drug shortages put patient care at risk and create additional burden and cost. The impact of these issues on hospitals and health systems is not easily known as a result of gaps in publicly available data sources. Whereas trends in retail drug spending are available through national data collection and reporting efforts, such as the National Health Expenditure data, those sources do not reflect the experience of major drug purchasers: hospitals and health systems. This report updates and expands upon a previous analysis on trends in hospital and health system experience with drug prices and spending. Growth in inpatient and outpatient drug spending exceeded the growth in the Medicare hospital payment rates for each setting during this period as well as the growth in general health care expenditures. Alongside the growth in drug spending, hospitals faced enormous challenges dealing with shortages: about 80 percent of responding hospitals found it extremely challenging to obtain drugs in short supply. This report provides insights on the challenges facing hospitals and the patients they serve. Drug spending in the inpatient setting is divided by total inpatient admissions per year to calculate drug spending per inpatient admission. This growth was driven primarily by changes in drug prices, including both higher launch prices and annual price increases, not utilization. However, prices have continued to increase for many drugs, while ongoing manufacturing shortages of many prescription drugs have threatened patient access to care. Hospitals and health systems, as major purchasers of prescription drugs, bear a heavy financial burden when prescription drug prices rise. These organizations purchase a high volume of drugs used to treat patients in both the inpatient and outpatient settings. In the inpatient setting, hospitals typically receive bundled payments either a per diem or diagnostic-related group payment to cover the total costs of an admission (including all services and drugs for a given stay). These bundled payments do not immediately adjust for increases in input costs like drugs. The budget pressures resulting from increased drug spending can have negative impacts on patient care with hospitals being forced to delay infrastructure investments, reduce staffing, and identify alternative therapies. Hospitals also continue to struggle with pharmaceutical shortages, which increase costs by disrupting typical work patterns and patient care, and often require significant staff time to address. Unlike retail drug purchases, prices paid for drugs in hospital settings are not readily available. To what extent did changes in drug prices contribute to changes in drug spending by hospitals? What measures and management strategies have hospitals used to control drug spending? What actions have hospitals used to continue caring for patients in light of drug shortages? Did hospitals perceive that new market entry resulted in more competitively priced drugs? Definitions the survey used the following definitions: Hospital drug spending per admission: this study includes hospital-based pharmacy spending on prescription drugs (injectable, non-injectable, and biological products) in inpatient and outpatient settings during the fiscal year net of discounts. Drug spending in the hospital setting is divided by total adjusted admissions per year to calculate hospital drug spending per admission. Drug spending in the outpatient setting is divided by the outpatient component of total adjusted admissions to calculate drug spending per outpatient encounter. Other specialty hospitals include obstetrics and gynecology; eye, ear, nose, and throat; rehabilitation; orthopedic; and other individually described specialty services. Community hospitals include academic medical centers or other teaching hospitals if they are nonfederal short-term hospitals. Drug shortage: the American Journal of Health-System Pharmacy defines a drug shortage as a supply issue that affects how the pharmacy prepares or dispenses a drug product or influences patient care when prescribers must use an alternative agent. Price: Price in this report is typically referred to as unit price or unit purchase price. For average price, weighted averages were taken based on spending on a drug across different suppliers, formulations, and dosages.

Microvascular disease may be related to shear stress in non-obstructed areas, post-capillary remodelling related to bronchial-to-pulmonary venous shunting, pressure, inflammation and release of cytokines and vasculotrophic mediators. This information is complementary to the typical clinical information collected by healthcare professionals. Chronic haemolytic anaemia the common feature of the haemolytic anaemias is that when there is intravascular haemolysis, there is release of cell-free haemoglobin into the plasma which scavenges the nitric oxide. A loss of nitric oxide, the physiological vasodilator of the pulmonary circulation, may cause vasoconstriction and vascular obstructive pathologic changes. Hereditary spherocytosis/stomatocytosis Hereditary stomatocytosis is a rare autosomal red cell membrane disorder and the red cells are subject to intravascular haemolysis. In addition, there is a high risk of thrombotic complications but, once again, this is often in association with splenectomy which is done to prevent the haemolysis. Systemic disorders associated with pulmonary hypertension these disorders include sarcoidosis, histiocytosis, and lymphangiomyomatosis. It may be due to proliferative vascular dysfunction, related in part to uraemia which is also known to affect the systemic vessels. Tumours Approximately 25% of patients dying with cancer die with tumour emboli in the pulmonary circulation. Tumour cells migrate to the pulmonary circulation where they seem to cause a microangiopathy.

Longitudinal analysis casts doubt on the presence of genetic anticipation in heritable pulmonary arterial hypertension. At the same time, clinical presentations associated with this entity are wide-ranging and overlap substantially with other heterogeneous diagnoses like irritable bowel syndrome. This ambiguity is compounded by a lack of standardized testing and treatment modalities, which can be frustrating for providers and patients alike. This traction is attributable not only to an accumulating foundation of empiric evidence, but also to a growing general interest in the role of gut microbiota in health and illness. Likewise, patients frustrated by a lack of definitive answers may be prone to perseverating upon this clinical entity given its elusive, protean, and faddish qualities. This excess of bacteria, along with their associated metabolic processes and byproducts, leads in theory to various forms of maldigestion. In a healthy state, proximal small intestinal microbiota are comprised primarily of Gram-positive aerobes, whereas the distal small bowel favors mostly facultative anaerobes in a gradient leading toward to the dense and almost exclusively anaerobic population of the colon. Elaborations in breath testing modalities have facilitated scrutiny of organisms producing methane and hydrogen sulfide as metabolic byproducts in response to an oral carbohydrate load, though the quantitative parameters for identifying them are subject to ongoing refinement. Methane production, for instance, is tied to constipation, perhaps by virtue of delayed gut transit. Risk Factors for Small Intestinal Bacterial Overgrowth Structural Abnormalities Post-operativeadhesions Smallboweldiverticula Smallbowelstrictures Blindintestinalloops Incompetentileocecalvalve Motility Abnormalities Chronicintestinal pseudo-obstruction Connectivetissuedisease. Breath tests are performed by asking patients to ingest a pre-specified carbohydrate substrate before quantifying exhaled gases at regular intervals as an indirect measure of small bowel bacterial metabolism. The choice of substrate is an important variable, since glucose is natively absorbed by the small bowel whereas lactulose is not; as such, glucose can be predisposed to more false negative results, while lactulose can lead to more false positives. In this context, the most common approach is to utilize a course of antibiotics to reduce bacterial burden and evaluate for symptom improvement thereafter. This strategy errs on the side of overtreatment; however, increasing the number of patients exposed to the potential risks of antibiotic therapy, including medication side effects, precipitation of C. A variety of antibiotics have been studied with roughly equivalent rates of success, suggesting that targeting specific bacteria may not always be necessary to facilitate the collapse of synergistic, polymicrobial colonies. Such maneuvers might include optimizing blood glucose control, withdrawing gut-slowing or acid-suppressing medications, and perhaps even selectively instituting prokinetic drugs. Misapprehensions that dietary modification can treat bacterial overgrowth, or that dietary indiscretion can lead to worsening dysbiosis, should be avoided. Providers should also counsel patients to keep their exclusions temporary and minimally restrictive, given the risk of developing disordered eating habits (that is, "orthorexia nervosa") and the potentially deleterious effects of carbohydrate restriction on the gut microbiome overall.

Before step up in treatment: Review adherence to medication, inhaler technique, and environmental control. If alternative treatment was used, discontinue and use preferred treatment for that step. Recommended Action for Treatment (See "Stepwise Approach for Managing Asthma Long Term," page 7) Regular follow-up every 16 months. The stepwise approach is meant to help, not replace, the clinical decisionmaking needed to meet individual patient needs. Consider short course of oral systemic corticosteroids if asthma exacerbation is severe or patient has history of severe exacerbations. The intensity of treatment depends on severity of symptoms: up to 3 treatments every 20 minutes as needed. Intermittent Asthma Persistent Asthma: Daily Medication Consult with asthma specialist if step 4 care or higher is required. The intensity of treatment depends on severity of symptoms: up to 3 treatments Quick-Relief Medication every 20 minutes as needed. If alternative treatment is used and response is inadequate, discontinue and use preferred treatment before stepping up. Theophylline is a less desirable alternative because of the need to monitor serum concentration levels. Based on evidence for dust mites, animal dander, and pollen; evidence is weak or lacking for molds and cockroaches. Clinicians who administer immunotherapy or omalizumab should be prepared to treat anaphylaxis that may occur. Zileuton is less desirable because of limited studies as adjunctive therapy and the need to monitor liver function.

Once asthma control is achieved and sustained at least 3 months, the dose should be carefully titrated down to the minimum dose necessary to maintain control. To reduce the risk of side effects, patients should work with their doctor to use the lowest dose that maintains asthma control, and be sure to take the medication correctly. This effect on linear growth is not predictable and is generally small (about 1 cm), appears to occur in the first several months of treatment, and is not progressive. Controlling asthma is important for pregnant women to be sure the fetus receives enough oxygen. A large clinical trial found that slightly more deaths occurred in patients taking salmeterol in a single inhaler every day in addition to usual asthma therapy* (13 out of about 13,000) compared with patients taking Daily use should generally not exceed 100 mcg a placebo in addition to usual asthma therapy salmeterol or 24 mcg formoterol. Understanding asthma Oxford Self-help guide Oxford Oxford Living with asthma Years ago, asthma was a debilitating condition that in many cases seriously limited what a person could do. Fortunately - as a result of greater knowledge about asthma and its treatment options - the ability to manage this disease has vastly improved over the years. In fact, life with asthma at times can even be extraordinary for Olympic gold medalists or professional athletes who break records - despite their asthma. Bring this book along to your next doctor visit and ask your health care provider to help you complete your personalized asthma action plan on pages 25 through 27. The word "asthma" is derived from a Greek word meaning "breathlessness" or "panting," both of which describe symptoms present during an asthma attack 2 Oxford Contents 1. Understanding asthma Oxford When you breathe, air moves through your nose or mouth down to your windpipe (trachea). Just as the windpipe meets the lungs, it branches off into two large airways (bronchi), one to each lung. Within the lungs, the large airways branch off into smaller airways (bronchioles) leading to many small air sacs (alveoli). Second, they remove carbon dioxide from your blood so it can be removed from your body when you exhale. Asthma interferes with normal breathing by narrowing the airways both within and leading to the lungs. When the airways are narrowed, the amount of carbon dioxide leaving the body and the amount of oxygen entering the body are both restricted. As these muscles contract or tighten, the space inside the airways narrows and less air is able to pass in and out of the lungs. The same triggers that cause bronchospasm can also cause ongoing (chronic) swelling and inflammation in the inner lining of the airways. Like bronchospasm, inflammation of the lining narrows the space available for air to pass through. When the lining of the airways is irritated and inflamed, bronchospasm is more likely to occur. The airways in a person with asthma narrow in response to triggers such as exercise or cold air. How easily this occurs is often referred to as twitchiness or bronchial hyperreactivity. Mucus normally coats the airways and cleans away small particles of foreign matter, such as dust and dirt, from the air passages. When the airways become inflamed during an asthma episode, too much mucus may be produced. As a result, it is more difficult to clear away the mucus by coughing, and bacteria can grow in the mucus, resulting in bronchitis. Many people with asthma experience times when they have more problems breathing and times when they feel perfectly normal. Fortunately, the airflow obstruction caused by asthma can be reversed, often rapidly. This is one of the key ways in which asthma is different from other diseases, such as emphysema. Others may experience wheezing, chest tightness, shortness of breath or any combination of the above. Asthma tends to run in families (about 40 percent of children who have parents with asthma will develop asthma), and most people who have asthma develop their first symptoms while still young. About half of those with asthma show symptoms before age 10, and most develop it before age 30. Because other illnesses and diseases can cause similar symptoms and difficult breathing, you should see your health care provider to determine whether the problem is asthma or something else. Be prepared to give specific information about when and under what circumstances your symptoms tend to occur. If you are the parent of a child who has asthma, keep in mind that about half of all children with asthma "grow out" of the disease and have lessening symptoms by the time they are 15 years old. The key to managing asthma is understanding your symptoms and learning what triggers and relieves them. Your answers to these kinds of questions will help your doctor develop a history of the problem. This history, together with a physical examination, will help your doctor decide if further tests are needed. If no other lung disease is present, chest x-rays will be fairly normal in a person who has asthma. The spirometer measures the amount and speed of air that is breathed out, indicating how open or narrow the air passages are. When the passages narrow during an asthma episode, the force of exhaled air measured by the spirometer is lower than normal. Some people who have asthma, however, may have normal spirometry results during times when they are symptom-free. This is one way your health care provider can tell that the problem is asthma and not emphysema or chronic bronchitis, both of which are diseases that cause irreversible damage to the lungs. The asthma spectrum Asthma can range from very mild and intermittent to severe and persistent, with a wide spectrum in between. Your grade of asthma depends on your daytime and nighttime symptoms, and your breathing test results. The severity of your asthma can change over time, depending on how your body reacts to different triggers at different times in your life. You may have Many people think asthma is a disabling disease - something that makes you unable to participate in sports, be active or enjoy life. This is not to say it will be easy for you to adjust to having asthma and to the things you need to do to take care of it. Learning that you have a chronic disease such as asthma can raise a variety of emotions - some not so pleasant. You may feel angry, frustrated or worried about what your future will be like living with asthma. These feelings usually pass as time goes by and you become more comfortable and confident that you really can manage this disease and prevent and treat asthma episodes. If you continue to struggle with feelings of frustration, anger, worry or fear, or if these feelings are interfering with your daily life or relationships, talk with your health care provider. He or she may be able to recommend a counselor or other mental health professional who can help you. Family, friends, co-workers, teachers and coaches can also provide valuable support if they understand asthma. Share what you know about asthma with the people who care about you, and let them know how they can help you if you have an asthma episode. Tracking asthma triggers For most people, asthma episodes are regularly triggered by one or more factors - allergens, infections, irritants, weather conditions, exercise, emotions or even aspirin products. What causes an asthma episode in one person, however, may not bother another person who has asthma. The first step in managing your asthma is identifying your asthma triggers and finding ways to avoid them as much as possible. Your immune system is designed to protect your body from harmful intruders such as bacteria and viruses. When one of these intruders, or antigens, enters the body, the immune system kicks in by releasing special chemicals to combat the invaders. Allergies that trigger asthma If you have a bacterial or viral infection, these may cause your body temperature to rise or your nose to run as a way of ridding the antigen from the body. In some people, the immune system can also react when the body is exposed to certain antigens, such as dust mites or pollen, that are not normally harmful to the body. Allergic reactions affect specific areas of the body: the skin - with rashes, itching, eczema or hives the nose - with runny nose, congestion or sneezing the eyes - making them itch, swell or become watery the airways - causing asthma the first clue that you may have an allergy is if you regularly experience allergy-like symptoms in specific situations. For example, maybe you have allergy symptoms only at certain times of the year or when you visit a home where a cat or dog lives. Maybe you have year-round symptoms, indicating that you might be allergic to something in your home, such as dust mites or molds. For example, a person who grew up on a maple-lined street may be well into adulthood before developing an allergy to maple pollen. Even though they may have taken months or years to develop, allergies may seem to pop up overnight. Common allergens to consider as you search for your asthma triggers include the following: Animal and insect allergens. Dogs, horses, guinea pigs, birds - just about any furry or feathered friend - may also trigger allergic reactions in some people. Different allergens cause different allergic reactions in different people with allergies. A food allergen, such as eggs or peanuts, may cause a person with that specific allergy to break out in hives. On the other hand, an airborne allergen, such as animal dander, pollen, mold or dust, may cause a runny nose or itchy eyes. Tree pollens are most abundant during the spring, grasses in the spring and summer, and weed pollens, such as ragweed, in late summer and fall. Dust mites (microscopic insects found in household dust) and fungi (mold and mildew) can cause year-round allergy symptoms. Dust mites and fungi especially like to breed in damp places and humid environments, such as the bathroom, basement and kitchen. He or she may recommend that you see an allergist (a doctor specializing in allergies) for allergy testing. During an allergy test, very small amounts of allergens are placed on (a "scratch test") or injected under your skin. If your skin reacts with redness or a raised, itchy bump where the allergen was placed, you are allergic to that allergen.
