Various reintroductions were taking place and the genetic origin of the released animals was unclear discount diltiazem 180mg otc medicine games. Subsequently discount 60 mg diltiazem with mastercard medications and breastfeeding, all lynx holding institutions were contacted and asked to send their historical reports for this species discount diltiazem online master card medications ritalin. Through intensive searching and questioning many discrepancies were resolved, yet a lot of information remained unknown. The most important conclusion from this analysis was that the registered records of Eurasian lynxes in many institutions were very poor. Many institutions registered their lynxes as Lynx without subspecifc identifcation. Also, many institutions automatically registered them as the nominate subspecies Lynx lynx lynx. Also, the increase in number of lynxes that were identifed as mixed origin was also remarkable (from 0 to 27, according to survey comparisons). Given that the determination of different subspecies is still unclear and that many assumptions have been made without proper scientific studies (e. This means that animals that appear in the studbook listed as pure subspecies, may not be pure at all, or might belong to another subspecies (e. As lynxes are easily available to zoos, there had never been standardized husbandry recommendations for this species. Besides from following animal welfare standards, there were no reasons for zoos to invest in good husbandry procedures. One of the tasks of a breeding programme is to provide husbandry guidelines for the species to upgrade the husbandry and welfare standards for the species in captivity. But because there is less attention for lynx than there is for larger, charismatic mammals, not much pressure was put on compiling husbandry guidelines for lynxes. With the help of students, basic guidelines were developed but not formally published. Slowly, zoos are improving their facilities and presently asking for advice on how to design new lynx enclosures and how to take care of their captive animals. Re c o m m e n d a t i o n s t h a t e m e R G e d f R o m t h e eu R a s i a n l y n x esb a n a l y s e s Due to the problems faced by Eurasian lynxes maintained in captivity, several recommendations were made to improve the husbandry and management of this species in zoos. All institutions that have related breeding pairs should cease breeding those animals and consult the studbook keeper for advice. Since there is a demand for pure Carpathian lynxes, zoos wanting to display this subspecies are encouraged to design and build large, naturalistic enclosures and provide enrichment opportunities. From the studbook management point of view, all lynxes from different origin are treated as subspecies until further scientifc research determines the validity of the subspecies or provides alternative conclusions. For instance, all lynxes originating from Slovakia are Carpathian lynxes, and all lynxes from Sweden are Northern lynxes (lynx subspecies). By using this strategy, the possible loss of important bloodlines might be prevented. All mixed progeny between lynxes from different origins is considered as hybrids, and a specifc non-breeding recommendation is forwarded in such cases. If genetic research eventually shows that within the Eurasian lynx there are this many subspecies, it would mean that zoos would have to manage seven different populations. If genetic research shows that only two clear subspecies can be recognised, then only two separate populations would need to be managed. They should preferably be of the same subspecies, or race, as those which were extirpated, unless adequate numbers are not available. This statement indicates that, prior to any Eurasian lynx reintroduction project there has to be a clear understanding of the genetic origin of the selected candidates for release. An important contact is the research group in Switzerland, which has already been involved with scientifc studies regarding lynx genetics (Breitenmoser-Wrsten et al. This approach will be important to help manage both captive and reintroduced populations.

Lo que s sabemos es que slo hay un planeta para seguir hacindolo y slo una especie capaz de cambiar las cosas de una forma considerable. En el Programa de conservacin Ex situ del Lince Ibrico se han criado a mano satisfactoriamente ocho cachorros desde el ao 2001. La crianza artifcial es un proceso delicado que se inicia con la recepcin del cachorro y fnaliza cuando ste es capaz de valerse por s mismo, en torno a los cuatro meses de edad. Durante el proceso de crianza, las variables a controlar y las tcnicas a emplear irn adaptndose a la edad del cachorro, siendo los primeros das de vida los ms crticos para 109 garantizar su supervivencia. El cachorro recin ingresado debe acostumbrarse a las condiciones del nuevo alojamiento (la temperatura ambiental debe estar en torno a los 30 0c y la humedad mantenerse al 50% durante la primera semana de vida), as como habituarse a la leche de reemplazo (se utilizan marcas con presencia del aminocido taurina en su composicin); al ritmo de lactancia (ocho tomas diarias de alimento cada tres horas durante los seis primeros das), y si no ha recibido calostro natural, se le debern suplementar los anticuerpos necesarios para reforzar su sistema inmune (aporte va oral de suero sanguneo de un adulto sano a razn de 2 ml/100 g cada 12 horas durante dos das). Segn los datos obtenidos a partir de cachorros criados a mano en el Programa de conservacin Ex situ todos ellos abandonados por sus madres un neonato de lince ibrico pesa aproximadamente 17518 g y tiene una temperatura corporal de 34,90. Entre el primer y tercer da de0 vida, los cachorros criados a bibern incrementan su peso en 173 g al da y rpidamente pasan a una tasa de crecimiento diario de 356 g entre los cuatro y 40 das de vida. A partir de la quinta semana, debe comenzarse el periodo de destete, que se completar en torno a los 100 das de vida. Para asegurar que los linces criados a mano presenten unas conductas afnes a los objetivos del Programa de conservacin Ex situ es preciso llevar a cabo, de forma paralela a la alimentacin y cuidados, un correcto programa de socializacin a partir de la segunda semana de vida de los cachorros. In the Iberian Lynx Ex situ Conservation Programme, eight cubs have been successfully hand-reared since 2001. Hand-rearing is a delicate process that starts when the cub is taken and fnishes when the individual is able to take care of itself, around the age of four months. During the hand-rearing process, the variables to control and techniques to use should be adapted to the age of the cub. Indeed, the frst days of a cubs life are most critical in guaranteeing its survival. According to the data obtained from hand-reared cubs in the Ex situ Conservation Programme all cubs had been abandoned by their mothers a neonate Iberian lynx weighs about 17518 g and has a body temperature of 34. Between the frst and the third day0 of life, the daily weight gain of hand-reared cubs is 173 g; between the 4thand 40thday of life, their mean daily growth rate is 356 g. Weaning should start around the ffth week of life and be completed around the age of 100 days. To ensure the behavior of hand-reared individuals matches the goals of the Ex situ Conservation Programme, an appropriate socialization programme should begin on the cubs second week of life, in parallel to the feeding and care of the cubs. Hand-rearing should only be considered when all factors and circumstances point to a high risk of disease and/or death of the cub, the mother or the cubs siblings.

It is also important to appreciate that diferent physical urticarias can occur concur- rently in the same patient; cold and cholinergic urticarias represent a well recognised ex- ample cheap 180 mg diltiazem with mastercard symptoms gestational diabetes. Furthermore buy generic diltiazem 60 mg line symptoms 5 weeks 3 days, chronic spontaneous urticaria is ofen associated with dermogra- phism or delayed pressure urticaria purchase 60 mg diltiazem with amex medications on airplanes. The investigation and management of chronic urti- caria should be infuenced by establishing the relative contributions of coexisting forms of chronic urticaria to the patients overall disability. Symptomatic Dermographism This common physical urticaria presents mainly in teenagers or adults of either sex. Like most physical urticarias, individual itchy wheals, produced by gentle stroking or rubbing of the skin, last less than 30 minutes before fading (Fig. Angioedema and mucosal wheal- ing do not occur but pruritus is troublesome and there are no systemic symptoms. Upper left hand panel: use of a graduated dermographometer to test for sensitivity to a dermo- graphic stimulus. Lower panel: gentle stroking by the round end of a pen with the gentle pressure may readily disclose abnormal reaction of patients ology is unknown although skin reactivity can be passively transferred to non-human pri- mates by intracutaneous injection of donor serum from a dermographic patient (Murphy et al. As with the majority of physical urticarias, investigations are pointless and any role for food items has not been substantiated. The prognosis is for eventual improve- ment in two to three years in most patients. Up-dosing non-sedating second generation H1 antihistamines and using combinations of H1- and H2-antihistamines may be useful. A small open study of patients responding poorly to fexofenadine showed a beneft on pruritus and whealing from narrow-band ultraviolet B phototherapy that lasted for 6 to 12 weeks from stopping treatment (Borzova, 2008). Cholinergic Urticaria Cholinergic urticaria is common in children and young adults, although rare in the elderly. However, the consensus report on defnition, classifcation, and diagnosis of urticaria (Zuberbier et al. Typical monomorphic sym- metrical maculopapular erup- tion evoked by heat or exertion or stress the grounds that the etiology involves sweating, for which the commonest stimulus is rais- ing the body core temperature rather than the application of an external physical stimu- lus. If the patient rests, cools of or 10 relaxes, the eruption subsides in 1545 minutes. It may be accompanied by angioedema and systemic symptoms in- clude wheezing or, rarely, symptoms of non-allergic anaphylaxis. Cholinergic urticaria can be disabling, especially when provoked by occupational or emotional triggers. Cholinergic urticaria can be distinguished from ex- ercise-induced angioedema or anaphylaxis because the latter cannot be induced by passive heating in a hot shower or bath. The local wheals can be blocked by atropinisation of the skin indicating involvement of acetylcholine, and histamine release has also been confrmed presumably derived from mast cells (Herxheimer, 1956). Wheal and fare reaction to autologous sweat and histamine release from their basophils have been demonstrated in some populations of patients with cholinergic urticaria (Adachi et al. Tese reactions appear to be mediated by specifc IgE, but the antigen in human sweat has not been identifed yet. The condition normally responds reasonably well to avoidance of provoking factors, together with regular daily treatment by an H1-antihistamine, especially in chil- dren. Some patients can achieve a degree of exercise tolerance by taking light exercise to bring out a minor exacerbation of symptoms several hours before undertaking more vigor- ous exercise or sport. Other drugs that may be benefcial when taken in conjunction with an H1 antihistamine include montelukast (Feinberg, 2008), hysocine butyl bromide (Ujiie et al. Systemic symp- toms are common and may be severe especially when provoked by extensive body im- mersion, as in sea-bathing. It re- sponds rather poorly to antihistamine treatment in all but the mildest cases and in chil- dren. Cold tolerance treatment (repeated cold exposure to induce a temporary refractory Fig. Local whealing response to applica- tion of an ice cube for 10 min 354 Clive Grattan, Michihiro Hide, and Malcolm W. Greaves state) is efective but requires a highly motivated patient (Bentley-Phillips et al. Delayed Pressure Urticaria This common and disabling physical urticaria may resemble angioedema in that the wheals are characteristically deep and of more than 24 hours duration (Lawlor et al. As its name suggests, whealing occurs following a latent period of 24 hours afer application of pressure perpendicular to the skin. Common examples of triggering factors include a tight waistband, tight footwear and golf club, tennis racquet, or steering wheel grips. Pain is more characteristic than itch although both may occur, and there is no angioedema and no mucosal involvement. A skin biopsy reveals an infammatory infltrate in which eosino- phils are prominent but there is no vasculitis. Up to 40 per cent of patients with chronic spontaneous urticaria in Caucasian populations, but possibly less population of Japan and Asian countries, have accompanying delayed pressure urticaria (Sabroe et al. Early claims of the value of the antihistamine cetirizine have not been substantiated and antihistamines are usually poorly efective. Non-steroid anti- infammatory agents are also usually disappointing and in severely disabled patients sub- stantial dosage with oral steroids (e. Sulphasalazine and anti-leukotrienes may be efective for patients with predominant delayed pressure urticaria who are not sensitive to non-steroidal anti-infam- matories (Engler, 1995). Other Physical Urticarias Tese are rare, and include solar urticaria (Ramsay, 1977), aquagenic urticaria (Sibbald et al. Although it may be useful to determine the action spectrum needed to evoke solar urticaria, generally no further investigations are needed beyond establishing the di- agnosis by appropriate challenge tests. Antihistamine therapy is helpful to varying degrees in members of this group, which will not be discussed further. The reader is referred to more detailed accounts of these physical urticarias published elsewhere (Black, 2004) Food Additive-Evoked Chronic Urticaria Many patients with chronic urticaria believe they have an allergy to food items but this is probably never the case in adults with continuous spontaneous wheals. The rare exception is young children where food allergy is said occasionally to present as chronic urticaria. The relationship between food intolerance (also known as pseudoallergy) and chronic ur- ticaria has been investigated in several recent studies (Magerl, 2010, Bunselmeyer, 2009). The gold standard for diagno- sis should be placebo-controlled double-blinded challenge testing (Pastorello, 1995; May, 1985) and in our urticaria clinics chronic urticaria can be demonstrably attributable to a food additive in no more than eight per cent of patients. Urticarial Vasculitis Urticarial vasculitis is included in some classifcations of urticaria (Grattan, 2007) because the clinical presentation overlaps considerably with chronic spontaneous urticaria even though it is also included in classifcations of small vessel vasculitis. The defning feature is the fnding of small vessel vasculitis on lesional skin biopsy. A full description of the eti- ology, pathomechanisms, clinical presentation, investigation and treatment is outside the scope of this article. However, the subject has been comprehensively reviewed (ODonnell and Black, 1995). Clinical Presentation and Investigation In contrast with chronic spontaneous urticaria, individual wheals are typically of duration greater than 24 hours.

Narrow blood vessels that are due to a buildup of plaque (fatty deposits) on their walls. Heart disease is any disease or condition that affects or damages the heart or blood vessels. Sometimes doctors or other health care professionals use the word cardiovascular to describe a number of diseases and conditions that affect the heart. A stroke happens when a blood vessel to the brain becomes blocked or when the vessel bursts open and blood can no longer reach the brain. Cerebrovascular is a broad term that includes stroke and other diseases involving the blood vessels that affect the brain. Facts About Heart Disease and Stroke Talking point: We often hear about the numbers of deaths that different diseases cause. For heart disease and stroke, these numbers are very large Heart disease and stroke are leading causes of death and severe disability in the United States. Talking Points: The high numbers of deaths from heart disease and stroke are only part of the story. Heart disease and stroke are also the leading causes of severe long-term disability among working-age adults. Having a disability means a person is unable to do some or all of the tasks of daily living. We often think of heart disease and stroke as affecting mostly men or older people, but heart disease is also the leading cause of death in womenand its a major killer of people in the prime of life. Young and old people alike need to understand what causes heart disease and stroke and also what can be done to prevent these conditions. Risk Factors for Heart Disease and Stroke Talking points: Heart disease and stroke have many of the same risk factors. A risk factor for heart disease or stroke is a behavior or condition that makes a person more likely to have heart disease or to have a stroke or heart attack. When you meet with community members, make sure to talk with them about these risk factors. Some risk factors cannot be changed, such as older age and family history, but this information is important to know. The good news is that people can prevent or lower their risk for heart disease and stroke by changing their behaviors. These habits include eating healthy foods, becoming more active, keeping or reaching a healthy body weight, and not using tobacco. The earlier someone chooses to adopt healthy lifestyle habits, the better, because heart disease can begin to develop in childhood. It is always good to encourage people of all ages to lead healthy lifestyles to reduce their risk of heart disease, stroke, and other health problems. Changing unhealthy habits is key for those who already have high blood pressure, high blood cholesterol, or diabetes. It is also important for those who have heart disease or who have had a heart attack or stroke. Everyone can have better health by following healthy lifestyles, taking their doctors advice, and taking medicines that their doctors may prescribe for them. Also, heart disease, heart attacks and strokes can be prevented by working with your health care team to reduce your risk. Before we learn about how we can prevent heart disease and stroke, we need to understand how the heart and brain work. Its about the size of your fst and is located almost in the middle of your chest beneath the breastbone. About one-third of the heart is on the right side of the body, and about two-thirds of the heart is on the left side. If the heart does stop for more than a few minutes, nutrients from food and oxygen carried by the blood cant get to the other organs of the body and they will be damaged. If the brain becomes damaged, it may become unable to send messages to the muscles and could leave a person unable to walk, talk, or to use his or her hands. Damage to the brain also can affect memory, emotions, learning, or just about any other activity or function depending on the part of the brain that is damaged. Because the brain controls such critical functions as breathing, heartbeat, and kidney function, a person can die if the brain is badly damaged. Talking Points: Earlier, we learned that heart disease and stroke have one thing in common. The blood vessels and the heart work together to bring blood to every part of the body. Every time the heart beats, it pushes blood through the blood vessels to all parts of the body. Blood vessels that carry blood away from the heart to the rest of the body are called arteries. In addition to carrying food and oxygen to all organs and tissues, blood picks up and takes away waste made by the bodys cells. Blood carries nutrients and oxygen to the cells and organs in all parts of the body through blood vessels. If the blood is blocked or cut off, the cells begin to die and the organs become damaged. Talking Points: A problem with blocked blood vessels or a problem with the hearts ability to pump blood can slow blood fow. As we learned earlier, the blood vessels that carry blood from the heart to the rest of the body are called arteries. Over the course of peoples lives, some of their arteries may harden and get narrower. This happens because of cholesterol, a waxy kind of fat that travels in the blood. When there is too much cholesterol, it can stick to the inside of blood vessels and form a buildup called plaque. A little plaque buildup on the walls of the blood vessels is a normal part of aging, but too much plaque buildup is dangerous. Over time, this plaque buildup makes the inside of blood vessels narrower than they should be. Then blood fow decreases, which slowly reduces the oxygen supply to other parts of the body. The plaque can clog an artery slowly, or pieces of plaque may break away and cause a blood clot to form suddenly. The clot can travel through the bloodstream to another part of the body and block a blood vessel, cutting off the oxygen supply all at once. If a piece of plaque or a blood clot blocks a blood vessel that feeds the heart, it can cause a heart attack.
