While there is not much incentive for developing serologic methods of diagnosing the swine infection, Rodríguez-Canul et al. Control: Health education for at-risk populations is the foundation of cysticerco- sis prevention. A study in China (see Source of Infection and Mode of Transmission) established that control of human cysticercosis required a combination of health education and treatment of taeniases (Cao et al. A study in Mexico evaluated the effects of health education about the disease by measuring the change in knowl- edge and habits and in the prevalence of swine cysticercosis before and after an edu- cation program that promoted knowledge about transmission of the parasite and the appropriate hygiene practices for preventing transmission. After program execution, there were significant changes in knowledge of the parasite’s biology, but behavioral changes were short-lived and less impressive. In addition to individual protective measures for humans, control measures for cysticercosis consist of interrupting the chain of transmission of the parasite at any of the following intervention points: the production of eggs by an infected person, the dissemination of eggs to the environment, the ingestion of eggs by the interme- diate host, the development of the cysticercus in the intermediate host, and the dis- semination of the cysticerci to the definitive host (Barriga, 1997).

Etiology: The agent of this disease is a cestode of various species of the genus Diphyllobothrium (synonyms Bothriocephalus, Dibothriocephalus). Nomenclature within the genus is still imprecise because the limits of intraspecific morphologic variation and the factors associated with that variation are not known. Some of the species currently consid- ered valid are: a dwarf form of Diphyllobothrium, described as D. The following species have been described in human cases found in arctic and subarctic communities: D. The par- asite requires two intermediate hosts: the first of these is a copepod (small, plank- tonic crustacean); the second, a freshwater fish from one of several species. The adult or strobilar form of the parasite lives in the small intestine of man, dogs, cats, bears, and other wild animals; it has a scolex without hooks or suckers with two sucking grooves or bothria, measures 3 to 12 m long and 10 to 20 mm at its widest part, and may have 3,000 to 4,000 proglottids. The gravid proglottids expel eggs from the intestine through a uterine pore, along with chains of proglottids that are empty or contain just a few eggs, which detach and are eliminated with the feces. The eggs eliminated in the host’s feces contain an immature embryo which, after incubating in fresh water for 10 to 15 days at 15–25 °C, forms a ciliated embryo called a coracidium. The coracidium, some 50–100 µm in diameter, emerges from the egg and remains in the water until it is ingested by the first intermediate host, a copepod crustacean. Ingestion must occur within 24 hours of eclosion because the coracidium loses its infectiveness rapidly; however, the embryo of the species that use marine fish as intermediate hosts can tolerate the semi-brackish water of estuaries or briny sea water. This embryo lodges in the coelomic cavity of the crustacean and, in 10 to 20 days, turns into a procercoid, a solid, elongated larva 6 to 10 mm long with a circu- lar caudal appendage. When the crustacean and larva are ingested by the second intermediate host, any one of a variety of fish, the procercoid migrates to the mus- cles and other organs of the fish and becomes a plerocercoid or sparganum in about a month. If the first fish is eaten by a larger fish, the transport or paratenic host, the plerocercoid simply migrates from one fish to the other. When the infected fish is eaten by a definitive host, the ple- rocercoid lodges in the small intestine and starts to grow until it matures, and it begins to release eggs after 25 to 30 days. The first intermediate host is an almost-microscopic copepod crustacean of the genera Diaptomus (the Americas), Eudiaptomus (Asia and Europe), Acanthodiaptomus (Alpine region, the Carpathians, Scandinavia, Tibet, and Turkestan), Arctodiaptomus (Ural Mountains region), Eurytemora (North America), Boeckella (Australia), or Cyclops (Africa, Asia, and Europe) (von Bonsdorff, 1977). The most important fish that act as second intermediate hosts in the transmission of D. The usual definitive hosts are carnivores and the intermediate hosts are fish of the genera Oncorhynchus and Salvelinus (Muratov, 1990). In southern Argentina, Revenga (1993) found that 9% of brook trout are hosts to D. But it also infects other fish-eating mammals, such as dogs, cats, swine, bears, and wild carnivores.
Liaising with territorial authority environmental health officers or other officials responsible for regulating the implicated site may be necessary buy generic sominex 25 mg on-line. Information from key individual(s) associated with the implicated event Before visiting the implicated site or premises associated with the event sominex 25 mg low cost, try to identify and make contact with key individual(s) involved with the event purchase 25mg sominex fast delivery. Establishing a good relationship with the person or people responsible for the event can expedite a fast and thorough investigation order sominex 25mg otc, and will encourage the adoption of control measures. During the initial discussion: present the basic details of the outbreak, frankly and openly. Clearly state that the source of the outbreak has not been identified at this stage (if this is the case), and explain that preliminary enquiries are necessary at an early stage to help guide the investigation do not present suspicions about the outbreak source, unless the epidemiological analysis is complete arrange a mutually acceptable time for the site visit identify whether there are any forthcoming events in which the circumstances of the common event under investigation may recur (i. Step 4: Conduct a site visit and inspection Site visits and inspections provide the interface between the investigation and control of an outbreak. Observations made during the site visit may reveal helpful clues about the outbreak source, address general hygiene and safety issues, and can directly lead to implementation of control measures regardless of the subsequent epidemiological findings. The site visit is likely to have maximum benefit if undertaken as soon as possible after identification of the suspect site. A prompt visit would try to identify, sample, cease or remove from sale any food that could be contaminated. Also this initial rapid visit may identify gross problems at the site which may be immediately controlled. A second visit may occur when more detailed information has been gathered and analysed An additional function of visiting premises potentially linked to an outbreak is to meet those involved face to face. This emphasises the importance of the investigation, and when carried out in a polite and professional manner, tends to enhance communication and co-operation. Key components of the site visit and investigation are inspection of the place, processes and people. Remember that while doing a site visit and investigation, more is missed by not looking than not knowing. Place Gain a general impression of the site and keep an open mind, as unforeseen factors relevant to the outbreak may become apparent. This ‘floors, walls and ceilings’ inspection is only useful insofar that it contributes to an assessment of risk, as contaminated food can emerge from a kitchen that appears hygienic. While examining the site, consider whether specimens of leftover material associated with the common event are available and can be collected for testing. Collect specimens immediately, but if there is a lot of speculation on causative factors such as the specific source, mode of transmission or aetiological agent, it may be best to store the specimens after collection and decide what to test later. Ideally, the combined results of the epidemiological, environmental and laboratory investigation will help to guide decisions about what to test. Be cautious about widespread testing of the environmental specimens collected, because routine environmental culturing usually leads to results that cannot be 55 interpreted. For example, many surfaces, areas or items will be contaminated by organisms that are not relevant to the outbreak or are part of the normal environment, and yet the return of a positive test may demand a response. Processes The initial site visit is an opportunity to broadly review all processes at the site. If multiple processes occur at the site, it may be too time-consuming to undertake a detailed risk assessment of them all at the initial stage. It is important to include aspects that tend to be overlooked, such as storage, distribution, instructions to consumers, product design and composition. The following ‘process sieve’ has been developed to help screen processes for further detailed review. The process sieve If the site is unusual or has not been previously encountered, systematically identify which processes may have a role in the sequence of events that led to the outbreak. This process sieve offers a simple framework for screening processes that will require closer examination using the points listed above. The following processes are likely to require close examination: processes developed to decontaminate raw materials (e. People If the outbreak pathogen could have been transmitted from a person, then it is very important to interview and screen potential human sources using the following steps: identify a list of all individuals who may have come into contact with the suspected outbreak source(s) interview each individual with a standard questionnaire. The questionnaire should cover issues such as the presence or absence of symptoms of the outbreak illness, recent medical care or hospitalisation, presence of illness among close household contacts, level of contact with the suspected source(s) and involvement in other paid or unpaid work (e. Further information on questionnaire design is contained in Appendix 2 collect specimens if appropriate. If the pathogen can be transmitted by asymptomatic carriers, then all individuals who have had contact with the suspected source(s) should be screened. Step 5: Full environmental risk assessment Full environmental risk assessment requires a reasonable level of knowledge about the technical aspects of the processes potentially linked to the outbreak. It is beyond the scope of this manual to provide detailed descriptions of environmental risk assessment procedures and standards for the wide range of industries and processes with outbreak-causing potential. Discuss the characteristics of the outbreak with a technical advisor to obtain the most appropriate reference material. For the water industry, this material should be held in public health risk management plans. If this is the case, it may be important to take measurements, such as temperature readings, directly from the process itself. Environmental investigation of dispersed outbreaks Some form of environmental investigation is likely to be required for dispersed outbreaks. Once the common source has been implicated from the epidemiological study, the objectives of the environmental investigation of dispersed outbreaks become the same as those for common event outbreaks (i. Prior to the implication of a common source, the environmental investigation of dispersed outbreaks has a role in collecting information about the origins of products, suspected to be the source(s) of the outbreak, in preparation for a potential recall or advisory warning when the results of the epidemiological investigation are available. A full environmental investigation of a site or premises considered to be the potential common source of a dispersed outbreak cannot begin until the site has been identified, usually from the results of a descriptive review of cases or from a full epidemiological investigation. Collecting environmental information about the sources of products that appear to be linked to cases can start at an early stage. Once a potential common source for a dispersed outbreak has been identified, background information should be collected as for the investigation of a common event outbreak. Information about food manufacturing processes, water treatment processes and distribution networks is likely to be important, depending on the outbreak source and aetiological agent. Environmental investigation of common site outbreaks The characteristics and requirements of an environmental investigation into common site outbreaks that have been traced to a specific site are very similar to those of common event outbreaks. The objectives of environmental investigation are to identify obvious hazards that may require immediate implementation of control measures, to collect specimens of implicated material and to develop a plan for further management of other hazards. As with common event outbreaks, collecting information about the suspected common source of the outbreak and a site visit should be undertaken early. Environmental investigation of institutional outbreaks A thorough investigation of an outbreak in an institutional setting should include an environmental component, particularly if an inanimate object is epidemiologically implicated as a possible means of transmission.

Most nations with a developed understanding of health inequalities accept that health systems sometimes need to take account of differences between population groups in order to achieve fairer outcomes. There is no logical reason why gender differences in health outcome should not be treated in the same way. If this is so obvious, why do our authors - from countries as culturally varied and geographically distant from each other as Malaysia and Denmark, New Zealand and Canada – report similar diffculties in persuading governments to pay particular attention to the health of men? One reason is the one we have just considered - the idea that the problem lies with men them- selves. This may lead to the regrettable political view that it is up to men to change, not services. This is a fallacious argument that fails to acknowledge men’s poorer health as the inequality that it is. Furthermore, as our authors report, cultural pressures and social expectations make help-seeking very diffcult for men all over the world. Some may argue that would be desirable - but the only realistic view to take is that change on that scale is not going to happen in the foreseeable future. Politicians and clinicians may have simply become so used to men dying sooner than women that they have ceased to wonder why it happens. This perception may be reinforced by the fact that – as we have seen – there are some potential biological explanations for some of the differences. This may lead people to regard men’s greater burden of premature disease and death as “natural”. Finally, there is the persistence of the view that gender inequalities only affect women. It should be made clear at this point that there are no negative views about women or women’s organisations to be found in this report. Nowhere does anyone take issue with the view that women are seriously disadvantaged in many areas of life in many countries. Several authors indeed, acknowledge a debt to women’s organisations, who have led the way on social change in recent decades. Unfortunately however, the widespread association of the very word “gen- der” solely with the concerns of women is extremely unhelpful. The chapter on “Gender Equity” in Closing the gap in a generation2, the World Health Organisation’s important recent report on the need for worldwide action to address health inequalties, does not contain a single sentence about male health. The opening paragraph illustrates the point very effectively: Gender inequities are pervasive in all societies. Gender biases in power, resources, entitle- ments, norms and values and in the organization of services are unfair. The following defnition of a male health issue has been proposed: A male health issue is one that arises from physiological, psychological, so- cial, cultural or environmental factors that have a specifc impact on boys or men and/or necessitates male-specifc actions to achieve improvements in health or well-being at either individual or population level3. This defnition acknowledges that there are more factors at play than the biological; that the health of men and boys cannot be divorced either from prevailing notions of masculinity or from the infuences of the wider world of (for example) work or relationships. By stressing however, that one of the defning characteristics of a male health issue is that “male-specifc” actions are needed to bring about an improvement, the defnition also recognises the crucial point that services will need to differ by gender in their design and content. In other words, that the onus is on policy-makers to take the initiative if they are serious about improving male health. At the same time it contains a greater number of examples of coun- tries where non-governmental organisations are still pressing their political leaders to begin to tackle the issue. In the absence of a political response, these non-governmental organisations are themselves often delivering programmes that target men’s poorer health. Although some of our authors are frustrated at the lack of progress, it is nonetheless positive that the issue is being discussed, at least to some extent, in all the countries described in this report. Of course this is to be expected; the eleven countries featured are all known to have ac- tivist organisations campaigning for change. It is entirely possible that there has been good - or even greater - progress in other countries but that this has not come to the attention of the edi- tors. It is perhaps more likely however, that that the majority of the world’s nations have not yet begun to consider strategies to improve the health of men. Where there has been suffcient progress to have resulted in government activity, that activity tends to fall into one of two categories. The frst is politically-led activity directly intended to improve male health by the development of dedicated policy and/or investment in health programmes targeted at men. Very strong ex- amples of this can be seen in the reports from Australia and Ireland. Ireland has recently seen the publication of what is believed to be the world’s frst national policy intended to improve the health of men. Australia has a long track record of activity on men’s health both at the level of community activism and at the level of government (both national and regional). At time of writing, Australia is also devel- oping a national policy for men’s health and has appointed a group of “Men’s Health Ambassa- dors” to inform government thinking and galvanise public opinion. Initiatives at this level are very much to be welcomed and are a tribute to the campaigning work of men’s health organisations as well as to the foresight of the governments concerned. A prob- lem with actions of this kind though is that they may be vulnerable to political change which has the potential to bring them to an end before they can become fully established. A clear exam- ple of this can be seen in the report from New Zealand where, in 2008, as a consequence of a change of government, the demise of a dedicated investment programme occurred within just a few months of its announcement. The second category of progress has been in those countries where an emphasis on gender equality in social policy overall has opened the door to arguments that men’s poorer health outcomes should be addressed within this context. This route is probably available in a good number of other nations too - at least in theory. The diffculty lies in shifting the obstructive public and political view that we have already described – the idea that “gender inequality” is a problem that affects only women. It can be diffcult to instigate a constructive debate on this issue and even more so 10 to achieve a workable understanding. The argument runs the risk of alienating politicians who adhere to the view that men can never be seen as disadvantaged.
From a research perspective buy 25 mg sominex fast delivery, little is known about the contribution of per- sonality factors to the development of blood order 25mg sominex fast delivery, needle buy sominex 25 mg amex, and medical phobias order sominex 25mg with visa. The notion that personality style may play a role is nothing more than speculation at this point. For example, a child who grows up with a diabetic parent requiring daily insulin injections would likely be exposed to injections on a regular basis. This regular exposure might protect the child from devel- oping a needle phobia, compared to an otherwise similar child who hasn’t had much exposure to needles while 34 overcoming medical phobias growing up. In other words, regular exposure to blood, needles, doctors, and dentists may protect people from developing medical phobias even if they later have a neg- ative experience in one of these situations. You have probably heard the old saying that if you fall off a horse, you need to get right back on to prevent fear from setting in. People who avoid doctors or dentists after experiencing a negative event (for example, a pain- ful needle) may be more likely to develop fear than peo- ple who force themselves back into the situation despite the negative experience. Did you experience some negative event that contributed to the onset of your fear or that led to a worsening of your fear? Can you think of anything you’ve read, heard, or seen that may have led to the development or worsening of your fear? To what extent does a fear of blood, needles, hospitals, doctors, or dentists run in your family? If you tend to faint in these sit- uations, do others in your family have a similar reaction? Various negative experi- ences, including traumatic events, observing others who are frightened, and coming across negative information about the situation, may contribute to a person’s fear. Factors such as per- sonality and previous exposure to the situation may mod- erate the influences of genetics and negative learning experiences. But facing a fear head-on can be quite overwhelming and may even feel impossible given where your fear is at now. As you read this, it may seem as though you’ll never be able to go to the dentist, see your doctor, or have blood taken. But there is a way you can do this; it involves taking many small steps toward your goal, rather than trying to do it in one big step. It may seem obvious to you that in order for your friend to combat her fear, eventually she would have to come into contactwithadog. Butshewouldn’thavetostartbygoing up to the biggest, scariest dog in the neighborhood. Instead, you might suggest that she start off with a 38 overcoming medical phobias less fearful situation, like looking at a video of a dog or perhaps looking at a small live dog from a reasonable dis- tance. Once she gets used to that initial practice, you might suggest that she get closer to the small dog, and once she gets used to that, you might suggest that she get very close and eventually even try petting the dog. Think about the small steps taken in learning to drive, learning a new sport, or learning to play a musical instru- ment. You wouldn’t suggest that a person who wants to run a marathon do a full marathon as his or her first-ever run. A list of small steps aimed at helping you reach your ultimate goal is called an exposure hierarchy. Thisisalist of situations you plan to expose yourself to, recorded in order of difficulty, or in order of how anxious or fearful they make you feel. Each situation is assigned a fear rating ranging from 0 to 100, representing the level of fear that the situation is likely to cause. A rating of 100 means the maximum fear you can imagine experiencing, and a rating of 0 means no fear at all. This rating of fear is developing a hierarchy 39 subjective because different people respond to particular situations with different levels of fear. If your primary emotion upon encountering the situ- ation is something other than fear (for example, disgust), you can use your ratings to measure that emotion instead. The remainder of this chapter will help you develop your own individualized exposure hierarchy for your particular fear of blood, doctors, dentists, or needles. Combining your initial list with the moderating variables in order to generate a list of more detailed items 4. We recommend that you complete the exercises described in each step as you read through them. It might help to think of the activities, situations, and objects that you presently avoid because of your fear. Think of the specifics that cause you to be scared in the situation: is it the sight of blood, is it the smell of a hospital, is it the sightofaneedle,isitthesoundofadentist’sdrill? At this stage, list as many items as you can think of, including items from a wide range of difficulty levels. In other words, include items that generate mild, moderate, and severe levels of fear. If an item seems so scary that you can’t even imagine doing it, make sure you still include it on the list! Here are some examples of hierarchy items that are not detailed enough and improved items with greater detail. These examples will help you to generate items with sufficient detail: Original item: Go to the doctor. Improved item: Have one tube of blood drawn by an experienced technician while sitting up and looking away, with my boyfriend present. For example, an item involving a needle can be turned into three items of varying difficulty by changing the specific details in the situation: 1. A very difficult item: Have three tubes of blood drawn by an unknown technician while sitting up and looking at the needle, alone. A moderately difficult item: Have three tubes of blood drawn by a familiar technician while sitting up and looking away, with my boyfriend present. A less difficult item: Have one tube of blood drawn by a familiar technician while lying down and looking away, with my boyfriend present. Try to include situations to which you can expose yourself fairly easily (albeit with extreme fear). In other words, don’t include items like “have triple bypass surgery” unless you actually want or need to have that procedure done. Think to yourself, “If I were to face this situation right now, how much fear would I have? Again, 0 means no fear at all, and 100 refers to the most fear you have ever experienced. Now rewrite your hierarchy items in order of the fear ratings associated with each one, with the highest- scored item (closest to 100) at the top of the list, and the 46 overcoming medical phobias lowest-scored item at the bottom of the list. Ideally, you want about ten to fifteen items that cross over a range of difficulty levels. If you have too many items with high fear ratings, think again about the variables you could change in order to make some items less difficult (changing the situation in some way, for example, stand- ing farther away or completing the exposure with a loved one present).
