Wasps usually build honeycomb nests under eaves and rafters and are relatively few in number in such nests 20mg erectafil with visa causes of erectile dysfunction in young adults. However effective erectafil 20 mg erectile dysfunction drugs covered by medicare, in some parts of the country, such as Texas, they are the most common cause for insect stings. In contrast to stinging insects, biting insects such as mosquitoes rarely cause serious allergic reactions. These insects deposit salivary gland secretions, which have no relationship to the venom deposited by stinging insects. Isolated reports also suggest that, on a rare occasion, mosquito bites have caused anaphylaxis. It is much more common, however, for insect bites to cause large local reactions, which may have an immune pathogenesis (2). Large Local Reactions Extensive swelling and erythema, extending from the sting site over a large area is a fairly common reaction. The swelling usually reaches a maximum in 24 to 48 hours and may last as long as 10 days. Most people who have had large local reactions from insect stings will have similar large local reactions from subsequent re-stings ( 3). Thus, people who have had large local reactions are not considered candidates for venom immunotherapy (discussed later) and do not require venom skin tests. Anaphylaxis The most serious reaction that follows an insect sting is anaphylaxis. Retrospective population studies suggest that the incidence of this acute allergic reaction from an insect sting ranges between 0. Allergic reactions can occur at any age; most have occurred in individuals younger than 20 years of age, with a male-to-female ratio of 2:1. These factors may reflect exposure rather than any specific age or sex predilection. Several clinical studies suggest that about one third of individuals suffering systemic reactions have a personal history of atopic disease. In most patients, anaphylactic symptoms occur within 15 minutes after the sting, although there have been rare reports of reactions developing later. Clinical observations suggest that the sooner the symptoms occur, the more severe the reactions may be. The clinical symptoms vary from patient to patient and are typical of anaphylaxis from any cause. The most common symptoms involve the skin and include generalized urticaria, flushing, and angioedema. Upper airway edema involving the pharynx, epiglottis, and trachea has been responsible for numerous fatalities. Circulatory collapse with shock and hypotension also has been responsible for mortality. The reason for this increased mortality rate in adults might be the presence of cardiovascular disease or other pathologic changes associated with age. Adults may have less tolerance for the profound biochemical and physiologic changes that accompany anaphylaxis ( 13,14 and 15). There are no absolute criteria that will identify people at risk for acquiring venom allergy. Most people who have venom anaphylaxis have tolerated stings without any reaction before the first episode of anaphylaxis. Even individuals who have died from insect sting anaphylaxis usually had no history of prior allergic reactions. The occurrence of venom anaphylaxis after first known insect sting exposure is another confusing observation, raising the issue of the etiology of prior sensitization or the pathogenesis of this initial reaction. People who have had large local reactions usually have positive venom skin tests and often very high titers of serum venom-specific immunoglobulin E (IgE); thus, these tests do not discriminate the few potential anaphylactic reactors. Anecdotal observations suggest that the use of b-blocking medication, which certainly potentiates the seriousness of any anaphylactic reaction, may also be a risk factor for subsequent occurrence of anaphylaxis in people who have had large local reactions. Many simultaneous stings (greater than 100) may sensitize a person, who then might be at risk for anaphylaxis from a subsequent single sting. This potential problem is now recognized more often because of the many stings inflicted by the so-called killer bees. After experiencing a large number of stings with or without a toxic clinical reaction, people should be tested to determine the possibility of potential venom allergy. After an uneventful insect sting, some people may develop a positive skin test, which is usually transient in occurrence. A report from Johns Hopkins suggested that if the skin test remains positive for a long period of time, 5 to 10 years, 17% of people have a systemic reaction after a subsequent sting ( 16). If these data were verified, it would raise the question of venom skin tests for individuals who have tolerated insect stings. If the test remains positive, people might be advised to have medication available for treatment of an allergic reaction. Currently, skin testing of people who have no allergic reaction from a single sting is not recommended. The natural history of insect sting anaphylaxis has now been well studied and is most intriguing. People who have had insect sting anaphylaxis have an approximate 60% recurrence rate of anaphylaxis after subsequent stings ( 17). Viewed from a different perspective, not all people presumed to be at risk react to re-stings. The incidence of these re-sting reactions is influenced by age and severity of the symptoms of the initial reaction. For example, children who have had dermal symptoms (hives, angioedema) as the only manifestation of anaphylaxis have a remarkably low re-sting reaction rate ( 17,18). On the other hand, individuals of any age who have had severe anaphylaxis have an approximate 70% likelihood of repeat reactions ( 17,19). When anaphylaxis does reoccur, the severity of the reaction tends to be similar to the initial reaction. No relationship has been found between the occurrence and degree of anaphylaxis and the intensity of venom skin test reactions. On occasion, these reactions have also been associated with an immediate anaphylactic reaction. People who have this serum sickness type reaction are subsequently at risk for acute anaphylaxis after repeat stings and thus are considered candidates for venom immunotherapy ( 20). Toxic Reactions Toxic reactions may occur as a result of many simultaneous stings. The differentiation between allergic and toxic reactions sometimes can be difficult. As noted, after a toxic reaction, individuals may develop IgE antibody and then be at risk for subsequent allergic sting reactions following a single sting. Beekeepers have high levels of serum venom-specific IgG, correlating to some extent with the amount of venom exposure (stings).

From weak old people who are sometimes miserable and bitterly disappointed by neglect buy erectafil 20 mg line erectile dysfunction drugs prostate cancer, they are turned into certified members of the saddest of consumer groups order erectafil 20mg free shipping erectile dysfunction treatment vacuum pump, that of the aged programmed never to get enough. But while it has become acceptable to advocate limits to the escalation of costly care for the old, limits to so-called medical investments in childhood are still a subject that seems taboo. The engineering approach to the making of economically productive adults has made death in childhood a scandal, impairment through early disease a public embarrassment, unrepaired congenital malformation an intolerable sight, and the possibility of eugenic birth control a preferred theme for international congresses in the seventies. Life expectancy in the developed countries has increased from thirty-five years in the eighteenth century to seventy years today. This is due mainly to the reduction of infant mortality in these countries; for example, in England and Wales the number of infant deaths per 1,000 live births declined from 154 in 1840 to 22 in 1960. While in gross infant mortality the United States ranks seventeenth among nations, infant mortality among the poor is much higher than among higher-income groups. In New York City, infant mortality among the black population is more than twice as high as for the population in general, and probably higher than in many underdeveloped areas such as Thailand and Jamaica. It would be equally reckless to claim that those changes in the general environment that do have a causal relationship to the presence of doctors represent a positive balance for health. Although physicians did pioneer antisepsis, immunization, and dietary supplements, they were also involved in the switch to the bottle that transformed the traditional suckling into a modern baby and provided industry with working mothers who are clients for a factory-made formula. The damage this switch does to natural immunity mechanisms fostered by human milk and the physical and emotional stress caused by bottle feeding are comparable to if not greater than the benefits that a population can derive from specific immunizations. For instance, in 1960, 96 percent of Chilean mothers breast-fed their infants up to and beyond the first birthday. Then, for a decade, Chilean women underwent intense political indoctrination by both right-wing Christian Democrats and a variety of left-wing parties. By 1970 only 6 percent breast-fed beyond the first year and 80 percent had weaned their infants before the second full month. But medicine does not simply mirror reality; it reinforces and reproduces the process that undermines the social cocoons within which man has evolved. Preventive Stigma As curative treatment focuses increasingly on conditions in which it is ineffectual, expensive, and painful, medicine has begun to market prevention. Along with sick-care, health care has become a commodity, something one pays for rather than something one does. The higher the salary the company pays, the higher the rank of an aparatchik, the more will be spent to keep the valuable cog well oiled. Maintenance costs for highly capitalized manpower are the new measure of status for those on the upper rungs. The medicalization of prevention thus becomes another major symptom of social iatrogenesis. It tends to transform personal responsibility for my future into my management by some agency. Usually the danger of routine diagnosis is even less feared than the danger of routine treatment, though social, physical, and psychological torts inflicted by medical classification are no less well documented. Diagnoses made by the physician and his helpers can define either temporary or permanent roles for the patient. In either case, they add to a biophysical condition a social state created by presumably authoritative evaluation. No one is interested in ex-allergies or ex-appendectomy patients, just as no one will be remembered as an ex-traffic offender. Professional suspicion alone is enough to legitimize the stigma even if the suspected condition never existed. The medical label may protect the patient from punishment only to submit him to interminable instruction, treatment, and discrimination, which are inflicted on him for his professionally presumed benefit. It turns the physician into an officially licensed magician whose prophecies cripple even those who are left unharmed by his brews. The mass hunt for health risks begins with dragnets designed to apprehend those needing special protection: prenatal medical visits; well-child-care clinics for infants; school and camp check- ups and prepaid medical schemes. The United States proudly led the world in organizing disease-hunts and, later, in questioning their utility. This assembly-line procedure of complex chemical and medical examinations can be performed by paraprofessional technicians at a surprisingly low cost. It purports to offer uncounted millions more sophisticated detection of hidden therapeutic needs than was available in the sixties even for the most "valuable" hierarchs in Houston or Moscow. At the outset of this testing, the lack of controlled studies allowed the salesmen of mass-produced prevention to foster unsubstantiated expectations. In any case, it transforms people who feel healthy into patients anxious for their verdict. In the detection of sickness medicine does two things: it "discovers" new disorders, and it ascribes these disorders to concrete individuals. The medical-decision rule pushes him to seek safety by diagnosing illness rather than health. The rejected children were re-examined by another group of physicians, who recommended tonsillectomy for 46 percent of those remaining after the first examination. When the rejected children were examined a third time, a similar percentage was selected for tonsillectomy so that after three examinations only sixty-five children remained who had not been recommended for tonsillectomy. These subjects were not further examined because the supply of examining physicians ran out. Medicine not only imputes questionable categories with inquisitorial enthusiasm; it does so at a rate of miscarriage that no court system could tolerate. In one instance, autopsies showed that more than half the patients who died in a British university clinic with a diagnosis of specific heart failure had in fact died of something else. In another instance, the same series of chest X-rays shown to the same team of specialists on different occasions led them to change their mind on 20 percent of all cases. Smith that they cough, produce sputum, or suffer from stomach cramps as will tell Dr. Up to one- quarter of simple hospital tests show seriously divergent results when done from the same sample in two different labs. Yet there is no evidence that a differential diagnosis based on its results extends either the life expectancy or the comfort of the patient. Many routine uses of X-rays and fluoroscope on the young, the injection or ingestion of reagents and tracers, and the use of Ritalin to diagnose hyperactivity in children are examples. When a test is associated with several others, it has considerably greater power to harm than when it is conducted by itself. Unfortunately, as the tests turn more complex and are multiplied, their results frequently provide guidance only in selecting the form of intervention which the patient may survive, and not necessarily that which will help him. No wonder that physicians tend to delay longer than laymen before going to see their own doctor and that they are in worse shape when they get there.
We typically classify rhinosinusitis as being one of two broad categories with different causes and courses: acute or chronic cheap erectafil 20mg with visa erectile dysfunction kits. Acute rhinosinusitis simply refers to an inflammatory episode lasting less than two weeks order erectafil mastercard xenadrine erectile dysfunction. Complete resolution of symptoms is typical in acute infections, as these are usually preceded or caused by viral infections of the nose and sinuses often called colds. If this inflammation is enough to impair the effective circulation and clearance of the sinuses, a bacterial infection of the sinuses (acute rhinosinusitis) may result. Acute rhinosinusitis can frequently be avoided if the cold is treated effectively with decongestants and anti-inflammatory medications. If acute infections recur very regularly (greater than four episodes yearly,) the possibilities of anatomic predispositions or issues with the immune system should be considered. Signs and Symptoms of Chronic Rhinosinusitis Facial pain and pressure including the cheeks, between the eyes, and forehead Nasal congestion or obstruction Drainage of discolored mucous from the nose or down the back of the throat (postnasal drainage) Alteration in the sense of smell or taste Aching of the upper teeth Headache Bad breath Fatigue Cough Table 2-1. It should be noted that a clear demarcation between allergies and other causes of chronic inflammation of the mucous membranes of the nose and sinuses could be difficult. For this reason protection from environmental and occupational irritants can be helpful in both allergic and non-allergic individuals. The relationship between asthma and chronic rhinosinusitis has been well described, and can best be understood by the fact that the entire upper respiratory tract is lined by the same type of mucous membrane, and therefore may react to similar irritants or allergens. The evaluation and management of chronic rhinosinusitis can be quite variable and complex. As the underlying cause is often exposure to some type of irritant whether it is a classical allergy or not, the detection of and protection from these irritants is quite helpful if possible. This evaluation may include formal allergy testing either by means of a blood test or evaluation by an allergist, and taking a careful history to determine if there is some preceding exposure or seasonal variation to the symptoms that may give some clue as to the irritant. If this cannot be practically achieved other options are considered and can be described as those that either decrease the body s exposure to the irritants, or those that attenuate the bodies response to the irritants. Practical ways of decreasing the body s exposure to airway irritants would include a mask or respirator designed to filter out the offending particles, or a nasal and sinus saline rinse applied immediately after a large exposure or on a regular basis in situations where the exposures are more persistent. This would include topical and systemic (usually taken by mouth) medications designed to minimize the inflammatory response. Some medications and nose sprays are intended for symptomatic relief, and some are intended to minimize the development of symptoms. This distinction is very important, and should be clarified with your physician in order to ensure proper use. In situations where symptoms persist even with carefully considered medical therapy, one must be evaluated for other factors. Certain defects of the immune system, either innate or acquired, may be considered. There are also anatomic factors that may warrant evaluation and possible treatment such as obstructing polyps, major deformities of the nasal septum, or narrowing or obstruction of the natural sinus openings. Benign and malignant tumors of the nasal cavities, though rare, have many of the same signs and symptoms as chronic rhinosinusitis, so evaluation is important if symptoms persist despite what would otherwise be considered adequate treatment. Sometimes a surgical procedure is helpful in addressing nasal obstructions or clearing the sinuses in order for them to clear more effectively. It should be noted that surgery is rarely if ever to be considered a cure for chronic sinusitis. It is simply one more tool that specialists have available in their armament in order to relieve most symptoms, and improve the body s ability to be more resilient when exposed to environmental allergens or irritants. As there are many occupational exposures that have been associated with higher incidences of certain types of sinus cancers, and the latency, or time between the actual exposure and the development of the resulting disease can be more than a decade, careful acquisition of all known exposures is important. Pharyngitis, Laryngitis, and Laryngopharyngitis Irritation of the throat has many names depending on where the irritation occurs. As the irritation is often not isolated to one specific area the term laryngopharyngitis, irritation of the throat and voice box, has become more favored. If the symptoms are severe, persistent, or progressive, prompt evaluation is neces- sary. Some forms of acute inflammation of the throat can progress to airway obstruction, and should be taken seriously. Persistent hoarseness can be a sign of something more serious, and should be evaluated if present for more than four to six weeks. Signs and Symptoms of Chronic Laryngopharyngitis Hoarseness or loss of voice Raw or sore throat Cough (typically dry) Difficulty breathing Sensation of a lump in the throat Trouble swallowing Table 2-1. While most cases of acute laryngitis are managed with self-care, chronic laryngitis, cases lasting for more than two weeks, should usually be managed only after discussing one s symptoms with a physician. Voice rest, adequate fluid intake, lubricants such as throat lozenges, and ensuring that the ambient air is humid without being contaminated with mold or fungus are excellent first steps to ensuring prompt recovery in cases of acute laryngopharyngitis. Cigarette smoking, allergies, repeated exposure to environmental irritants, and voice overuse are often substantial risk factors. In some situations, evaluation of the voice and the throat and vocal cords by a specialist is necessary. This exam is often aided by performing a laryngoscopy procedure in which a very small fiberoptic scope is placed in the throat in order to view the mucous membrane surfaces and architecture with excellent resolution. The coordination of the muscles of the larynx can be examined as well as the vibrations of the vocal cords when using specialized instruments. As the treatment of chronic laryngopharyngitis largely depends on what is the underlying cause, a specialist evaluation is sometimes necessary in order to determine what that cause is. One common cause that warrants further discussion is chronic laryngopharyngitis due to reflux disease. This disorder refers to the backflow of stomach contents through the esophagus and potentially into the larynx and pharynx. When the reflux is limited to the esophagus, it may cause erosions that are experienced as heartburn (a burning sensation in the middle of the chest. This is due not only to the fact that the esophagus has more protective properties, but that the reflux is not spending enough time in the esophagus. As the esophagus is better suited to withstand the irritation of stomach contents such as acid, often a patient will have throat symptoms suggestive of laryngopharyngitis prior to experiencing traditional heartburn. Reflux can occur day and night, and often takes place even hours after a meal (Table 2-1. In cases where reflux is suspected, there are other tests that may confirm the presence of acid in the throat and the esophagus. The data acquired is subsequently uploaded into a computer and provides an excellent picture of the amount and timing acid reflux. Another test uses an endoscope consisting of a light and camera that is inserted down the throat and into the esophagus. It can detect erosions or abnormal changes in the lining of the esophagus and stomach. Steps for Minimizing Symptoms of Chronic Laryngopharyngitis Avoidance of airway irritants such as smoke, dust, and toxic fumes- sometimes by use of a mask or respirator. Avoid talking too loudly or for too long Avoid whispering which causes increased strain on the throat Avoid clearing your throat Keep your throat moistened and your body hydrated by drinking plenty of non-alcoholic fluids Avoid upper respiratory infections by washing your hands regularly and after any contact with people you suspect of being sick Treat potential underlying causes of laryngopharyngitis including reflux, smoking, or alcoholism Table 2-1. Potent anti-inflammatory medications including corticosteroids are sometimes helpful, and in circumstances when reflux is a major factor and conventional reflux lifestyle precautions fail to improve symptoms, antireflux medications or potent antacids may be prescribed.
