In captivity, birds are usually offered the same diet A routine preventive medicine program should be year-round. In contrast, free-ranging Psittaciformes designed around a detailed health history for the must forage for food. Many of these foods will be seasonally available as dictated by the wet and dry seasons, which often control the reproductive cycles. The sea- sonal provision of extra soft foods prior to the onset of the breeding season may stimulate reproduction. Birds that are housed outdoors are exposed to natu- ral sunlight and should not require supplemental Vitamin D3. Macaws are especially susceptible to Vitamin D toxicity, which could be potentiated by unnecessary supplementation. Facility Design An aviary should be designed to be easy to maintain while providing safety, security and sanitary condi- tions for its inhabitants. A part of making a bird feel secure is to provide it with a defendable space (its enclosure), which is rarely, if ever, violated. Additional factors in providing a se- cure environment include having visual barriers to separate the nesting areas of secretive birds, and keeping louder, more boisterous birds (eg, macaws) widely separated from quieter, more timid birds (eg, African Grey Parrots). Indoor/outdoor facilities pro- vide the most natural conditions for the birds, but may be unsatisfactory in urban areas. In these situ- ations, properly designed indoor facilities can be used to successfully raise birds. However, these facilities are more labor-intensive and increase the likelihood Indoor Facilities: Indoor housing has several ad- of disease outbreaks.

Desert species may that might be used as a model was designed to hold prefer a more sunny, open aviary while forest species up to 24 pairs of birds and was completely constructed may feel more secure in wooded or secluded aviaries. The con- crete floor was sealed with a waterproofing agent to make cleaning easier and more effective. Two, covered four- to six-inch drainage pipes that drain water outside the perimeter fence were placed in each end of the building, and an easily removable sink was installed in one end. The sides of the building were made of concrete block with holes to the outside placed at the desired height (bottom of the bird’s cage floor) and at numerous horizontal intervals (the num- ber would depend on the width of the interior and exterior enclosures). A strip of florescent lighting was positioned down bowls and nest box dry can be used to breed birds in appropriate the center of the building. The enclosure can be constructed over concrete pads with installed in the attic of the building with four evenly a drainage ditch to one side for ease of cleaning. The lighted indoor facility is made of concrete blocks on a concrete slab for ease of cleaning. The outdoor flights are connected to the indoor flights through a hole in the concrete block. Note the height of the enclosures, which provides extra physiological security for the birds, and the perimeter fence with a “kill zone” to discourage unwanted intruders (eg, raccoon, opossums, rats, snakes) (courtesy of Apalachee River Aviary).

A suspended enclosure is separated from the a wire brush and rinsed immediately to remove loose ground and is not entered by aviary personnel. Alcove servicing also prevents escapes because an enclosure door is not opened to gain access to the food and water containers. These alcoves can be de- signed to slide onto the floor or to fit under the floor of the enclosure. Some aviculturists flights in being easier to clean and less expensive to construct and in reducing the birds’ access to contaminated food or droppings.

Large Perches must be secure and non-movable in order to flights are aesthetically pleasing to people and pro- provide an optimal site for successful copulation. However, these enclosures are difficult to clean and to maintain pest- or parasite-free. Additionally, avi- ary personnel walking from one enclosure to the next can serve as mechanical vectors for the transmission of infectious agents. Enclosures should be designed with access locations that allow the capture of birds with minimal chasing. Escape proofing is suggested and may be accom- plished by safety aisles or suspended safety netting.
With treatment order metoclopramide 10 mg amex, the person should be considered infectious until the mites and eggs are destroyed order 10mg metoclopramide, usually 7–10 days discount metoclopramide 10 mg on line. Management in Custody Because transmission is through direct skin-to-skin contact with an infected individual, gloves should be worn when dealing with individuals suspected of 258 Nicholson infestation. Usually prolonged contact is needed, unless the person has crusted scabies, where transmission occurs more easily. The risk of transmission is much greater in households were repeated or prolonged contact is likely. Because mites can survive in bedding or clothing for up to 24 hour, gloves should also be worn when handling these items. Treatment The preferred treatment for scabies is either permethrin cream (5%) or aqueous Malathion (0. Either treatment has to be applied to the whole body and should be left on for at least 8 hours in the case of permethrin and 24 hours for Malathion before washing off. Lindane is no longer considered the treatment of choice, because there may be complications in pregnancy (42). Treatment in custody may not be practical but should be considered when the detainee is believed to have Norwegian scabies. General Information Like scabies, head lice occur worldwide and are found in the hair close to the scalp. The eggs, or nits, cling to the hair and are difficult to remove, but they are not harmful. Route of Transmission Head lice can only be passed from direct hair-to-hair contact. Management in Custody It is only necessary to wear gloves when examining the head for what- ever reason. The cell does not need to be cleaned after use, because the lice live on or near skin. Bedding may be contaminated with shed skin, so should be handled with gloves and laundered or incinerated. The presence of live lice is an indication for treatment by either physical removal with a comb or the application of an insecticide. General Information Crabs or body lice are more commonly found in the pubic, axillary, chest, and leg hair. Routes of Transmission The main route is from person to person by direct contact, but eggs can stick to fibers, so clothing and bedding should be handled with care (see Sub- heading 6. Clothing or bedding should be handled with gloves and either laundered or incinerated. Treatment of a detainee in custody is good in theory but probably imprac- tical because the whole body has to be treated. The eggs and larvae fleas can survive for months and are reactivated in response to animal or human activity. Because animal fleas jump off humans after biting, most detainees with flea bites will not have fleas, unless they are human fleas. After use, the cell should be vacuumed and cleaned with a proprietary insecticide. Any bedding should be removed wearing gloves, bagged, and either laundered or incinerated. General Information Bedbugs live and lay eggs on walls, floors, furniture, and bedding. Bedbugs are rarely found on the person but may be brought in on clothing or other personal effects. Management in Custody The detainee does not need to be treated, but the cell should deemed out of use until it can be vacuumed and professionally cleaned with an insecticide solution. Any bedding or clothing should be handled with gloves and disposed of as appropriate. Epidemiology Staphylococcus aureus is commonly carried on the skin or in the nose of healthy people. Approximately 25–30% of the population is colonized with the bacteria but remain well (43). From time to time, the bacteria cause minor skin infections that usually do not require antibiotic treatment. During the last 50 years, the bacteria have become increasingly resistant to penicillin-based antibiotics (44), and in the last 20 years, they have become resistant to an increasing number of alternative antibiotics. Like nonresistant staphylococci, it may remain undetected as a reservoir in colonized individuals but can also produce clinical disease. It is more common in individuals who are elderly, debilitated, or immunocompromised or those with open wounds. Route of Transmission The bacteria are usually spread via the hands of staff after contact with colonized or infected detainees or devices, items (e. Staff should wear gloves when touching mucous membranes, nonintact skin, blood or other body fluids, or any items that could be contaminated. They should also be encour- aged to their wash hands with an antimicrobial agent regardless of whether gloves have been worn. After use, gloves should be disposed of in a yellow hazard bag and not allowed to touch surfaces. Masks and gowns should only be worn when conducting procedures that generate aerosols of blood or other body fluids. Because this is an unlikely scenario in the custodial setting, masks and gowns should not be necessary. Gloves should be worn when handling bedding or clothing, and all items should be disposed of appropriately. The cell should be cleaned professionally after use if there is any risk that it has been contaminated. Epidemiology During the last decade, there has been an increasing awareness of the bacterial flora colonizing injection sites that may potentially lead to life-threat- ening infection (48). By June 12, 2000, a total of 42 cases (18 definite and 24 probable) had been reported. Until the end of 1999, there were no cases reported to the Public Health Leadership Society. Since then, the number has increased, with a total of 13 cases in the United Kingdom and Ireland being 262 Nicholson reported since the beginning of 2002. It is believed that these cases are associ- ated with contaminated batches of heroin. Simultaneous injection of cocaine increases the risk by encouraging anerobic conditions. Anerobic flora in wounds may have serious consequences for the detainee, but the risk of transmission to staff is virtually nonexistent. Management in Custody Staff should be reminded to wear gloves when coming into contact with detainees with infected skin sites exuding pus or serum and that any old dress- ings found in the cell should be disposed of into the yellow bag marked “clini- cal waste” in the medical room. The cell should be deemed out of use and professionally cleaned after the detainee has gone. The health care professional managing the detainee should clean and dress open wounds as soon as possible to prevent the spread of infection. It may also be appropriate to start a course of antibiotics if there is abscess for- mation or signs of cellulites and/or the detainee is systemically unwell. How- ever, infections can often be low grade because the skin, venous, and lymphatic systems have been damaged by repeated penetration of the skin. In these cases, signs include lymphedema, swollen lymph glands, and darkly pigmented skin over the area. Fever may or may not be present, but septicemia is uncommon unless the individual is immunocompromised (e. Co- Amoxiclav is the preferred treatment of choice because it covers the majority of staphylococci, streptococci, and anerobes (the dose depends on the degree of infection). Necrotizing fasciitis and septic thrombophlebitis are rare but life-threat- ening complications of intravenous drug use. This includes encouraging drug users to smoke rather than inject or at least to advise them to avoid injecting into muscle or skin.

His findings, that man possesses some "extra sen- sory factor," which he calls "Psi," are no longer doubted by scientists who have seriously reviewed his work. Rhine, "that there is a ca- pacity for acquiring knowledge that transcends the sen- sory functions. This extra sensory capacity can give us knowledge certainly of objective and very likely of sub- jective states, knowledge of matter and most probably of minds. Many creative artists, as well as psychologists who have made a study of the creative process, have been impressed by the similarity of creative inspiration, sudden revelation, intuition, etc. Searching for a new idea, or an answer to a problem, is in fact, very similar to searching memory for a name you have forgotten. The scanner in your brain scans back over stored memories until the desired name is "recognized" or "discovered. Norbert Wiener has said, "Once a scientist attacks a problem which he knows to have an answer, his entire attitude is changed. If you really mean business, have an intense desire, and begin to think intensely about all angles of the problem—your creative mechanism goes to work—and the "scanner" we spoke of earlier begins to scan back through stored information, or "grope" its way to an answer. It selects an idea here, a fact there, a series of former experiences, and relates them—or "ties them to- gether" into a meaningful whole which will "fill out" the incompleted portion of your situation, complete your equation, or "solve" your problem. When this solution is served up to your consciousness—often at an unguarded moment when you are thinking of something else—or per- haps even as a dream while your consciousness is asleep —something "clicks" and you at once "recognize" this as the answer you have been searching for. In this process, does your creative mechanism also have access to stored information in a universal mind? How else, for example, explain the ex- perience of Louis Agassiz, told by his wife: "He had been striving to decipher the somewhat obscure impression of a fossil fish on the stone slab in which it was preserved. Weary and perplexed, he put his work aside at last and tried to dismiss it from his mind. Shortly after, he waked one night persuaded that while asleep he had seen his fish with all the missing features perfectly restored. The next night he saw the fish again, but when he waked it disappeared from his memory as before. Hoping the same experience might be repeated, on the third night he placed a pencil and paper beside his bed before going to sleep. He hastened to the Jardin des Plantes and, with his drawing as a guide, succeeded in chiseling away the surface of the stone under which portions of the fish proved to be hidden. When wholly exposed, the fossil corresponded with his dream and his drawing, and he suc- ceeded in classifying it with ease. There must be some grounds, some justification, some reason for deciding that the old picture of self is in error, and that a new picture is appropriate. You cannot merely imagine a new self-image; unless you feel that it is based upon truth. Experience has shown that when a per- son does change his self-image, he has the feeling that for one reason or another, he "sees," or realizes the truth about himself. The truth in this chapter can set you free of an old in- adequate self-image, if you read it often, think intently about the implications, and "hammer home" its truths to yourself. Science has now confirmed what philosophers, mystics, and other intuitive people have long declared: every human being has been literally "engineered for success" by his Creator. Study it and digest it Look for ex- amples in your experiences, and the experiences of your friends, which illustrate the creative mechanism in action. You do not need to be an electronic engineer, or a physicist, to operate your own servo-mechanism, any more than you have to be able to engineer an automobile in order to drive one, or become an electrical engineer in order to turn on the light in your room. You do need to be familiar with the following, however, because having memorized them, they will throw "new light" on what is to follow: 1. It operates by either (1) steering you to a goal already in existence or by (2) "discovering" some- thing already in existence. The automatic mechanism is teleological, that is, oper- ates, or must be oriented to "end results," goals. It is the function of the automatic mechanism to supply the "means whereby" when you supply the goal. Think in terms of the end result, and the means whereby will often take care of themselves. All servo-mechanisms achieve a goal by nega- tive feedback, or by going forward, making mistakes, and immediately correcting course. Skill learning of any kind is accomplished by trial and error, mentally correcting aim after an error, until a "successful" motion, movement or performance has been achieved. You must learn to trust your creative mechanism to do its work and not "jam it" by becoming too concerned or too anxious as to whether it will work or not, or by attempting to force it by too much conscious effort. This trust is necessary because your creative mecha- nism operates below the level of consciousness, and you cannot "know" what is going on beneath the surface. It comes into operation as you act and as you place a demand upon it by your actions. You must not wait to act until you have proof—you must act as if it is there, and it will come through. A particularly memorable instance of this fact con- cerned a patient who was literally forced to visit my office by his family. He was a man of about 40, unmarried, who held down a routine job during the day and kept himself in his room when the work day was over, never going any- where, never doing anything. He had had many jobs and never seemed able to stay with any of them for any great length of time. His problem was that he had a rather large nose and ears that protruded a little more than is normal. The poor man even imag- ined that Ms family was "ashamed" of him because he was "peculiar looking," not like "other people. His nose was of the "classical Roman" type, and his ears, though somewhat large, attracted no more attention than those of thousands of people with similar ears. His imagination had set up an automatic, negative, failure mechanism within him and it was operating full blast, to his extreme misfortune. Fortunately, after several sessions with him, and with the help of his family, he was able gradually to realize that the power of his own imagination was responsible for his plight, and he succeeded in build- ing up a true self-image and achieving the confidence he needed by applying creative imagination rather than de- structive imagination. We act, or fail to act, not because of "will," as is so commonly be- lieved, but because of imagination. A human being always acts and feels and performs in accordance with what he imagines to be true about him- self and his environment. When we see this law of mind graphically and dramati- cally demonstrated in a hypnotized subject, we are prone to think that there is something occult or supra-normal at work. Actually, what we are witnessing is the normal operating processes of the human brain and nervous system. For example, if a good hypnotic subject is told that he is at the North Pole he will not only shiver and appear to be cold, his body will react just as if he were cold and goose pimples will develop. Tell a hypnotized sub- ject that your finger is a red hot poker and he will not only grimace with pain at your touch, but his cardiovas- cular and lymphatic systems will react just as if your finger were a red hot poker and produce inflammation and perhaps a blister on the skin. When college students, wide awake, have been told to imagine that a spot on their fore- heads was hot, temperature readings have shown an actual increase in skin temperature. Your nervous system cannot tell the difference between an imagined experience and a "real" experience. In either case, it reacts automatically to information which you give to it from your forebrain. Your nervous system reacts appropriately to what "you" think or imagine to be true. Theodore Xenophon Barber has conducted exten- sive research into the phenomena of hypnosis, both when he was associated with the psychology department of American University in Washington, D. C, and also after becoming associated with the Laboratory of Social Rela- tions at Harvard. A little reflection will show why it is a very good thing for us that we do feel and act according to what we be- lieve or imagine to be true. Truth Determines Action and Behavior The human brain and nervous system are engineered to react automatically and appropriately to the problems and challenges in the environment.

Examination At the end of the course a written final assessment will be organized in the form of multiple choice questions. The result of this assessment will determine the verification mark of the credit course using the following conversion table: 0-39. The program is conducted between 3rd and 11th academic weeks of the second semester. Tutor can be any professor of the Department, not only her/his seminar/practical instructor. The applicant should contact the chosen professor and request him/her to undertake the tutorship. Professors of the Department maintain the right to accept or refuse to be the tutor of the applicant. Preconditions for the program: mark three (3) or better in Physiology I, successful closing lab and permission of the Department (arranged by the tutor). In case, the number of applicants is higher than 100, the seminar/practical instructor or the course coordinator can refuse applicants with mark three or better. The name of the students registered to the program is published on the website of Department of Physiology on the 3rd academic week. Two students works in team on one project, and prepare one mutual report, thus they get the same score at the end of the program regardless their contribution. Evaluation of the students is based on the written report or the oral presentation using five grade score system (1-5). The list of offered programs are available at the practical lab of the Department or on the Department’s homepage (http://phys. Appendix or supplementary material, all together no longer than 20 pages, containing data or methodological information can be attached to the manuscript if it is necessary. Easy reading of the text should be considered as primary importance when choosing typeface and font size. Instead of pursuing artistic view, the format of the text should serve the content. Page numbering starts on front page (can be hidden); footnotes and page headings should be used sparingly. The text should be written in good English/American, but prevent using the mixtures of these. Use standard abbreviations where possible, and always give definition at first use. A caption should have a brief title and short description of the illustration with a compact conclusion. All sections should begin on new page, headings typographically separated from the text, centered between left and right margins. Requirements for the sessions: - Front page should contain the followings (template is available at the course coordinator). State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results. Flow-charts, diagrams or photographs to demonstrate critical methodological steps or simplify long descriptions are welcomed. Raw data can be used only as representative recordings or examples if necessary, appropriate use of statistical methods is critical when presenting results. Attempts to resolve contradiction between your own data or your data and the literature is greeted. The reviewers evaluate the manuscripts on a five grade scale according to the following criteria. Numerous stylistic or typographical errors without influencing the readability of the text. Satisfactory is given if illustrations are not clear, graphically not well presented or hard to understand the message. Selected method is appropriate but the manuscript has several substantial flaws in the analysis or the write-up. Inappropriate statistical method, insufficient data or numerous stylistic, typographical errors in text or graphical errors in illustrations results pass too. A fail should also be given if the manuscript reveals a fundamental lack of understanding of the concept presented or the stylistic/grammatical/graphical errors have severe impact on the readability of the text. Missing the deadline result fail with no regard to the content or format of the manuscript. Nevertheless, the lecture material is going to be asked in the frame of the final assessment. The lectures of credit course are listed at the web site of the Department of Physiology (http://phys. Examination At the end of the course a written final assessment will be organized, using test (multiple choice) questions. If somebody missed the test or want to improve his/her results, an extra test will be provided on the first week of the exam period. There is no further possibility to get mark, if somebody miss both possibilities his/her mark will be Failed.
