It is important to remember that the lumbar spine has a greater component of gray over white matter and this is the reason why lower lumbar lesions can be harder to differentiate from peripheral neurological disorders and orthopedic pathologies definition depression de l'air amitriptyline 25 mg online. Fibrocartilaginous embolic myelopathy is an important syndrome that results from embolization of the arterial or venous supply to an area of the spinal cord anxiety used in a sentence safe 25mg amitriptyline. The mechanism by which the material reaches the vasculature of the spine is unknown but suspected to be secondary to extruded material entering the venous system or vertebral bone marrow depression symptoms physical purchase amitriptyline 50 mg with amex. Literature suggests a 79% rate of recovery with the majority of the patients returning to normal emotional depression definition amitriptyline 50mg fast delivery. Feline hyperesthesia syndrome is a poorly understood condition that has been recognized in practice with increased frequency depression vs sadness cheap amitriptyline 25 mg overnight delivery. Affected cats intermittently display clinical signs of rippling of the skin over the dorsum and muscles spasms of the thoracolumbar region as if this was resulting from an irritative phenomenon depression men purchase 50mg amitriptyline overnight delivery. Recent evidence of inclusions bodies found in histopathological samples suggests the origin of the condition maybe a myopathy. Rimmed intramyofiber vacuoles, containing paired helical filaments and beta-amyloid, were found in biopsies from affected cats. The condition can present with violent biting and licking at the flank/back area, agitated behaviour and vocalization. Therapy with corticosteroids, phenobarbital and gabapentin/pregabalin has been attempted with variable success rates but the overall prognosis tends to be poor with progression of clinical signs. The most common neoplastic disorder includes meningiomas of the brain or spinal cord. History and presenting clinical signs reflect the location and secondary effects (haemorrhage, edema) of the tumor. It has been reported that up to 20% of cats with intracranial neoplasia present for lethargy, inappetence and anorexia without any specific neurological dysfunction. Multiple intracranial meningiomas have been reported to occur in cats with a frequency as high as 17%. Lymphoma, gliomas and choroid plexus tumors are the other malignancies than can affect the feline brain. Meningiomas in cats represent the neoplastic disorder with a hopeful prognosis since the masses tend to be well encapsulated and easy to isolate during surgery from the surrounding tissue compared to other tumors. Once a diagnosis is made, therapy and dosing requires choices and then monitoring. None of these tests are without false negatives and false positives, therefore case selection is important prior to performing a screening test. The main use of the serum cortisol:creatinine ratio is in its almost 100% sensitivity, however 75% of dogs with non-adrenal illness will have an abnormal result therefore additional testing is required if a positive result is returned. In a normal dog, cortisol levels should be suppressed after administration of dexamethasone for the entire 8 hour test period, typically to less than 27 nmol/L. This test is affected by stress, and therefore it is important to try to minimize stress during the test. This product has a much higher cost than synacthen, and there are protocols that allow for multiple uses of one vial. Cortisol levels should be measured prior to injection of Cortrosyn (0 hour), and at 1 hour post administration of Cortrosyn. Therapy and monitoring Treatment for hyperadrenocorticism includes trilostane or mitotane, and in specific cases, surgery or radiation therapy. Previously recommended selegiline hydrochloride, ketoconazole or bilateral adrenalectomy should not be used for therapy. Mitotane is effective in most cases and slightly less expensive, however it more commonly causes side effects. Options for obtaining trilostane include use of Vetoryl, and compounded trilostane. There are now several sizes of Vetoryl available, including 5 mg, 10 mg, 30 mg, 60 mg, and 120 mg. This has reduced the need to use compounded trilostane in order to make small changes in dosage. Using a criteria of acceptability of 90-105% of expected drug present, 38% of the compounded capsules failed acceptable criteria. As the cost of Vetoryl is now competitive with compounded trilostane, given the new sizes of Vetoryl available, it is worth considering the source of trilostane used at your clinic. However, it is important to note that this is reserved for clinically well dogs, and calm dogs. Aggressive or overly anxious dogs, along with unwell dogs, should not utilize this method for assessing control of hypercortisolemia. My current recommendation is to consider this method in your well-controlled patients. Surgery (hypophysectomy) or radiation therapy should be considered in cases with neurologic signs or large macroadenomas. Functional adrenal tumours are best treated surgically, however both mitotane and trilostane have shown benefit in treatment. Mitotane is more ideal as it is adrenolytic, however a small study showed good efficacy with either therapy. Chemotherapy can also be considered if a definitive diagnosis is obtained; histopathology is required as cytology of adrenal masses has been shown to disagree with histopathology in a significant number of cases. In order to avoid possible side effects or over-dosing of these medications, a lower starting dose is advocated. For clients, this is perceived as an increase in cost, an increase in visits to the veterinary clinic, and a delay in control of clinical signs. Pre-trilostane and three-hour post-trilostane cortisol to monitor trilostane therapy in dogs. The bacteria are maintained in the renal tubules of the reservoir host and excreted in the urine. The two most familiar clinical syndromes of leptospirosis involve renal or hepatic dysfunction; however, patients may also present with conjunctivitis, uveitis, respiratory distress secondary pulmonary hemorrhage, acute febrile illness, pancreatitis and bleeding tendencies. Rapid diagnosis and treatment is imperative for patient survival, as the prognosis is excellent in most cases if antimicrobial therapy is started early in the course of disease. Diagnostic Options There are several options available for the diagnosis of leptospirosis, and selection of the appropriate test or tests is not straight-forward. The vaccination history of the dog must be considered, along with recent use of antimicrobials. Polymerase chain reaction is a relatively rapid test that detects Leptospira nucleic acid in blood, urine, cerebrospinal fluid and aqueous humor, although paired blood and urine testing is the most common method of detection. In clinical infections the time of infection is unknown, therefore simultaneous testing of blood and urine is recommended to increase diagnostic sensitivity. Even if a dog has not had recent antimicrobial therapy, a negative result does not rule out leptospirosis because samples may have been obtained when organism numbers in a sample are low. While a positive result confirms infection, a negative test should prompt additional testing to rule out leptospirosis as there is the possibility of a false negative result. The administration of a Leptospira vaccine prompts an antibodybased immune response. Therefore, a positive antibody test could be detecting antibodies made in response to the vaccine, as opposed to antibodies made in response to an infection with Leptospira spp (a false positive). However, the duration to which a leptospirosis vaccine affects the outcome of an antibody test is test-dependent. The new Witness antibody test detects IgM antibodies, which are relatively short-lived after vaccination. Therefore, most dogs will have a negative Witness test within 1-3 months of vaccination. The Witness Leptospira Antibody Test was introduced in the spring of 2018 in Canada. This test provides a negative or positive, without information on the infecting Leptospira serovar. As IgM antibodies are produced early in the course of disease, and their production decreases a few weeks after infection, the test is only useful for acute leptospirosis infections. The Witness test is affected by vaccination (false positive), but only for a few weeks after vaccination. Because IgM levels begin to rise a few days after infection, it is possible to have a negative result early in the course of disease (false negative). Due to the low cost of the test, this is more feasible than with many of the other tests. The Witness test is an in clinic test that can be performed within 20-30 minutes, and utilizes whole blood, plasma or serum. Although a single positive titer can increase suspicion for the disease, it does not always confirm a diagnosis, especially if the dog has been vaccinated for leptospirosis at any time in their life. A four-fold increase in titer supports recent infection; convalescent titers in vaccinated dogs are generally stable or decreased after 2-4 weeks, unless vaccination was very recent. This test provides a negative or positive, as seen with the Witness test, without information on infecting serovar. The test will be positive in dogs for months to years after vaccination, therefore may be positive in dogs with up to date vaccination, and also potentially in dogs with out of date vaccination. A negative result is useful in ruling out leptospirosis unless the dog was infected very recently, in which case a false negative is possible. A positive result in a dog that has never received a Leptospira vaccine confirms leptospirosis. Given the utility of the Witness Leptospira antibody test and its low cost, it is worth using as the primary test for leptospirosis. However, other approaches are needed if the dog has been vaccinated in the previous few weeks. However, in the general healthy population, compared to the risks of not vaccinating, the risks associated with immunization are very small. As vaccines are designed to stimulate an immune response, it is not surprising that a predisposed individual may overreact to vaccination due to the production of inflammatory mediators. Patients that are affected by primary epilepsy can be vaccinated with routine protocols. Primary Epilepsy is considered when the individual develop seizures between 6 months to 6 years of age and a structural cause of the seizures is not present. It is reasonable to associate the potential development and aggravation of immune-mediated disorders to diseases in individuals that are genetically predisposed. Age of onset of disease and previous vaccines received are other factors to consider. Research has shown that if a modified live-virus vaccine is given after 6 months of age, it should produce lifelong immunity. If another modified live-virus vaccine is given, the antigens of the second vaccine are mostly neutralized. The serum antibody titer is boosted only transiently and additional immune memory cells are not induced; Thus, annual boosters maybe unnecessary. The University of Wisconsin and the Rabies Challenge Fund Charitable Trust are currently conducting research regarding rabies vaccines. The goal is to extend the legally required interval for rabies boosters to 5 and then 7 years. Another way to protect patients with partial or no immunity is through high vaccination coverage in the population. When large groups of individuals are vaccinated, they create "community immunity". The more antigens administered in a vaccine, the greater the chance of inducing hypersensitivity. There is no scientific evidence to support that vaccines induce epilepsy in dogs and cats. It is important to remember that a temporal association between vaccination and the development of a clinical sign does not necessarily equate to a cause and effect relationship between the vaccine and the illness. It is possible that stressful situations or specific medications lower seizure threshold in a patient that is already predisposed. This is a different scenario to the epileptic patient who experiences repeated seizure activity from genetic predisposition. In some cases, animals that are experiencing an allergic reaction or pronounced inflammatory reaction may be reported by the veterinarian as experiencing tremors, or impaired mental status. Neurological signs which have been reported as possible adverse vaccine events include head tremor/bobbing, encephalitis, head pressing, convulsion/seizure, rigidity, weakness, impaired mental state, abnormal posture, ataxia, high stepping, recumbency, and altered reflexes. Table 1: Suspected adverse reactions for small animals (dogs, cats) vaccines reported to the Canadian Centre for Veterinary Biologics between 2010 and 2014. The histopathological diagnosis was viral non-purulent meningoencephalitis with severe demyelination in all dog cases. Historically, complications following rabies virus vaccination have received the most attention. Veterinary clinicians are seeing an increase in neurological diseases associated with vaccinosis. The Purdue University School of Veterinary Medicine conducted important studies to determine if vaccines alter the immune system of dogs. The study showed that blood from all of the vaccinated dogs contained significantly elevated concentrations of antibodies directed against proteins. One of the biochemical marker proteins that generated reactive antibodies in the vaccinated population included Anti-cardiolipin.

However anxiety books order 25mg amitriptyline amex, the authors of this study have not found a protocol in the literature that clearly defines patient selection, optimal surgery time, which corticosteroid to use, and the best administration route for this type of drug. The patients consent included the option to quit the research at any time, with no consequences to their treatment. Of these, 1 became pregnant after the first surgery, 2 did not show up at their postoperative appointments, and 4 did not return after the first surgery. The final study group included 27 male and female patients, with an age range of 15 to 41 years. This study was a randomized, paired, and double-blinded, longitudinal clinical trial. Exclusion criteria were any surgeries that lasted >1hour and/or presented any type of complications during and after the operation, patients who used postoperative painkillers other than acetaminophen, Surgical procedure the order in which the selected patients were submitted to the surgical procedure was randomized. For each patient, the left mandibular third molar was extracted first, then the right mandibular third molar was extracted 15 days later. After each extraction, the patients were examined 2 times (at 24 and 48 hours) for pain, swelling, and trismus. Dexamethasone was administered 1 hour before surgery; the doses were randomized and different for each extraction-for example, if the patient was given 4 mg before the first surgery, he/she would be given 12 mg before the second surgery. An incision was made with a scalpel to expose the surgical site and mucoperiosteal detachment, then an ostectomy and odontosection was performed with surgical spherical burs (No. Bone regularization, alveolar ridge cleaning, and suture with 4-0 silk thread (Ethicon, Inc. The patients received postsurgical instruction: semiliquid foods for the first 48 hours, bed rest, and avoidance of ice packs so as not to interfere with the postoperative swelling assessments. Each patient was medicated immediately for postsurgical pain with an oral administration of acetaminophen (750 mg) (Cetafrim, Luper Industria Farmaceutica Ltda). Acetaminophen was given to each patient with instructions to take 1 pill every 6 hours only if pain was present. Each patient then informed the researcher at the 24- and 48-hour postoperative evaluations how many pills he/she had taken. To assess postoperative swelling, new measurements of the facial points were done at both 24 and 48 hours. The surgery, data collection, and suture removal were all performed by the same researcher. To avoid the patients knowing the amount of the administrated dose of dexamethasone, and to maintain the doubleblind conditions of the research, both doses of the drug (4 and 12 mg) were manipulated so that all the pills were the same size and color, with no listed specifications. Postoperative evaluations Each patient returned for 24- and 48-hour postoperative evaluations. The mouth opening and facial points that were measured at 24 and 48 hours postoperative were substracted from the preoperative measurements with the same dexamethasone dosage. To evaluate whether there were differences in trismus and swelling on postoperative Days 1 and 2, the measurements taken at the 48-hour evaluation were substracted from the measurements taken at the 24-hour evaulation. Results the study population consisted of 27 patients: 17 women (63%) and 10 men (37%), ages 15-41 (21. Patients treated with 4 mg of dexamethasone had a mean surgical time to remove the impacted teeth of 24. The most prevalent position for the displaced mandiubular third molars was vertical (51. Swelling the paired t-test analysis of the relationship between facial swelling-at 1-hour preoperative and 24- and 48-hour postoperative-and the doses of dexamethasone (4 and 12 mg) showed no significant difference between the 2 doses of dexamethasone at either postoperative time (P = 0. A significant increase on the calculated means between pre- and postoperative times was observed between the 2 doses. According to the Wilcoxon test, there was no significant difference between the amount of acetaminophen tablets used for the 2 different doses at 24 hours or 48 hours postsurgery (P = 0. According to the Friedman test, there was no difference between the 2 doses of dexamethasone and the level of pain at postoperative 24 and 48 hours (P = 0. A study by Esen et al evaluated 20 patients with bilateral displaced third molars and recorded the number of painkillers taken postsurgery after a corticosteroid (methylprednisolone 125 mg) was administered 1 hour before the first surgery vs the number of painkillers taken postsurgery after a placebo was administered 1 hour before the second surgery. However, in another study of displaced third molar surgery, Grossi et al found no significant difference in the amount of drugs taken postsurgery when they compared patients who received 4 mg dexamethasone versus patients who received 8 mg preoperatively. This would suggest that both doses presented the same effect in relation to swelling. In another lower third molar surgery study, Paiva compared the effects of preoperative doses of dexamethasone (4 and 8 mg). This may be due to the fact that the area requires extensive manipulation of the surrounding tissues and also because the surgery involves cutting through part of the masseter region that includes the buccinator muscle. In a study by Lago-Mendez et al, the authors correlated postoperative pain to the degree of surgical difficulty in 139 patients. Patients who had longer surgical procedures reported greater pain intensity on postoperative Days 0 (day of surgery), 5, and 6. A study by Al-Khateeb & Nussair also demonstrated that the length of the surgical procedure can be directly correlated to the degree of difficulty in such surgical extractions, and consequently, can also be related to the intensity of the swelling presented by the patient postsurgery. According to Peterson et al, the mesioangular position of the mandibular third molar is the most prevalent, affecting approximately 45% of the teeth. These data also agree with Aguiar et al who found a higher prevalence of vertical impacted teeth. These results were further corroborated by Oliveira et al, who found that trismus and other complications-such as paresthesia and alveolitis-are directly correlated to the degree of difficulty of the surgery, whether or not the surgery involved an osteotomy, and whether the procedure required a prolonged surgical time. This would suggest that the different doses presented similar effects, and have no impact regarding limited mouth opening postoperatively. Flores et al investigated the use of anti-inflammatory medication and/ or antibiotics in third molar surgery. In the same study, it was also reported that no significant relationship between the use of such medicines and the level of surgical trauma could be found. Cornia & Anawalt reported that the dose and duration of supplemental steroids used traditionally may produce adverse reactions such as infections, and delay the healing process. However, no significant difference was found when comparing the preoperative values with the values measured on postoperative Day 7. The results suggest that this is due to the fact that the investigated drug has a desired therapeutic effect at either dose. The data also suggests that the 12 mg dose of dexamethasone and the 4 mg dose presented the same therapeutic effect on the evaluated variables at both 24 and 48 hours postsurgery. Thus, it can be concluded that both doses are effective and there is no need to use the larger dose to ensure successful postoperative management of these variables.

The silorane-dedicated adhesive system is available in a selfetch version which, according to the manufacturer, was created to fulfill the criterion of simplification; that is, using the reduced number of operative steps found in self-etch adhesive systems. The following were exclusion criteria: high caries risk (presence of incipient lesions, plaque, and/or xerostomia), generalized periodontal disease, a removable or fixed orthodontic appliance, signs of bruxism or clenching, more than 1 unit absent from the posterior region, poor oral hygiene, and pregnancy. Preoperative bitewing radiographs were taken of the teeth that were to be restored. Randomization was determined by selecting the restorative system (via a coin toss), then using the selected system on the tooth with the lowest number. Clinical procedures All cavities were prepared under local anesthesia and rubber dam isolation (Hygienic Dental Dam, Coltene/Whaledent, Inc. In cases with deeper areas, a calcium hydroxide lining (Kerr Life, Kerr Dental) was used. Before the start of treatment, patients were informed of the research methodology, risks, and benefits, as well as their right to withdraw from the research at any time. A sectional metal matrix, fixed with an elastic ring (Garrison Dental), was installed to restore the proximal contact and marginal ridge. Increments of resin composite (maximum thickness of 2 mm) were placed and photocured. Occlusal anatomy was developed using hand instruments before the composite was cured at the occlusal surface.

The potential economic impact of deer for each deer management region relates directly to the amount of commercial forest land in the region. Generally, the potential impact decreases from northern Wisconsin to southern Wisconsin. The acreage and percent forest coverage within each region is as follows: Northern Forest Region - 8,227,100 acres (71%), Central Forest - 1,394,200 acres (48%), Western Farmland - 1,857,700 acres (33%), Eastern Farmland 2,081,000 acres (33%), and Southern Farmland - 1,791,300 acres (18%).

The data presented in this appendix were provided for a regional analysis of vehicle-deer collisions, the data is based on data gathered in 1994. In some regions of Wisconsin, where habitats can support over 80 deer per square mile, overwinter population goals are primarily determined by human tolerance. Vehicle-deer collisions are a primary factor in determining just how many deer people will accept. Accurate counts of total vehicle-deer collisions are not possible, because not all deer carcasses are located and removed from the roads. Others cause little property damage and accident reports are not filed to the Department of Transportation. Since 1985, Wisconsin motorists have reported an average of almost 36,000 vehicle-deer collisions per year (unpublished). Recent studies indicate that actual figures may be more than double reported figures (unpublished). Costs of property damage and personal injury resulting from vehicle-deer collisions in Wisconsin were estimated at $92 million per year (Hall 1991). Vehicle-deer collisions throughout the state have steadily increased during recent years. A definite trend has emerged, indicating a relationship between both numbers of deer hit and overall deer population, as well as numbers of miles driven. Research has shown that the number of vehicle-deer collisions is dependent on both the deer density and the overall volume of traffic (McCaffery 1973b). As deer densities increase, the number of vehicle-deer collisions will increase as well, even when traffic volume remains constant. Likewise, when traffic volume increases and deer densities remain constant, vehicle-deer collisions will increase. Decreases in deer density will result in fewer deer hit by vehicles, assuming traffic volume remains constant. Risk of vehicle-deer collisions has not been reduced by whistles, roadside reflectors, or fencing (Ford and Villa 1993; Dalton and Stanger 1990; Romin and Dalton 1992). The only known way to efficiently reduce deer collision hazards, without reducing traffic, is by reducing deer numbers. Areas with high human populations and travel often have the highest incidence of vehicle-deer collisions. For example, counties surrounding the Madison, Milwaukee, and Green Bay metropolitan areas have some of the highest frequency of vehicle-deer collisions in the state each year (1. One 11-county area in South-Central Wisconsin makes up a region that has the highest overwinter deer density goals in the state - 30 or 35 deer per square mile of deer habitat. This area is primarily agricultural range with few major human travel corridors, so it has a significantly lower volume of vehicle traffic than the metropolitan areas previously mentioned. However, in terms of number of deer killed per square mile, this area experiences the highest level of vehicle-deer collisions in the state, leading to the conclusion that the high deer population in this area contributes significantly to high rates of vehicle-deer collisions. Any increase in deer numbers is expected to result in higher numbers of vehicle-deer collisions, particularly considering that traffic volume is not likely to decline. Similarly, decreases in deer numbers would be expected to result in lower levels of vehicle-deer collisions. This area also receives substantially lower levels of vehicle traffic compared to southern Wisconsin. As a result, fewer vehicledeer collisions occur here when measured per square mile as well as actual numbers of reported accidents. However, low levels of vehicle-deer collisions are the result of low traffic volumes. If traffic volume were to increase in this region, vehicle-deer collisions would be expected to increase as well. Although no major human travel areas fall within this region, two of its boundaries are major highways (I 90-94 and Hwy. With deer goals ranging from 25 to 30 deer per square mile, vehicle-deer collisions would be expected to rise with any increase in overall deer numbers. This region also contains several major highway systems, and receives high levels of commuter traffic in the counties east of Minneapolis - St. The combination of high deer population goals (ranging from 20 to 30 deer per square mile) and high levels of commuter traffic results in much of this region having a vehicle-deer collisions rate of more than 1. Western counties have the lowest incidence of vehicle-deer collisions with few major highways and lower human density, and deer goals ranging from 15 to 25 deer per square mile. Central counties, primarily centering around I-90/94 and the Madison metropolitan area, have deer density goals of 30-35 deer per square mile; more than one vehicle-deer collisions per square mile occur. Eastcentral counties have deer densities goals of 10-30 deer per square mile, but have considerably lower volumes of traffic than counties to the east or west, and therefore, vehicle-deer collisions decrease to between 0. Finally, the far eastern counties in the Milwaukee metropolitan area, with deer density goals of just 10-20 deer per square mile have a high incidence of vehicle-deer collisions due to high traffic volume. Increases in deer densities, increases in traffic volume, or both will result in more vehicle-deer collisions. Decreasing deer population goals would be expected to result in reductions in vehicle-deer collisions. Areas of high deer population goals and human vehicle traffic typically experience the highest levels of collisions. The only efficient method of reducing vehicle-deer collisions without reducing the number of miles travelled is to reduce deer numbers. Such areas typically lie in the Northern Forest region, as well as being scattered throughout other areas of the state. Areas of highest concern are primarily in farmland regions where deer goals equal or exceed 25 deer per square mile, and in metropolitan areas with high traffic volumes. Major travel corridors, such as interstate highways, also have high instances of vehicle-deer collisions. Reflector use and the effect they have on the number of mule deer killed on California highways. Deer baiting is the deliberate placement of food items for the purpose of attracting or habituating deer to a location for the purpose of hunting. Feeding does not include the placement of food and attractants for the purpose of hunting deer. Supplemental feeding normally involves placing larger quantities of food or mineral to augment naturally occurring foods. The purpose may be to attract, concentrate, and hold deer on specific parcels of land or to locally increase carrying capacity for deer and/or antler development. Emergency feeding has involved the deliberate placement of food during unusually severe winters, mainly to mitigate winter losses of deer. References to feeding in this document refer to all forms of feeding unless specified otherwise. But, historic prohibitions on using bait for waterfowl and use of salt for attracting deer may have fostered widespread belief that baiting of deer was illegal. Recent surveys of Wisconsin hunters found that relatively few (13%-16%, Borgerding 1993; 16%, Dhuey and McCaffery 1999, Dhuey 2001) firearm hunters reportedly used bait. The proportion of archers using bait continues to increase as about a third (34%) of archers used bait in 1997 (Dhuey 1998). A survey in 1992 found that most (53% to 66% depending on issue) hunters recognized some problems with baiting and only 32% were in favor of allowing baiting for both gun and bow hunting. However, fewer than half favored a baiting ban in all hunting seasons (Petchenik 1993). Recreational feeding of deer by some rural resorts, restaurants, taverns and residents have had a long tradition wildpro. Both government agencies and private individuals have provided supplemental food to deer. Private individuals have traditionally been mostly landowner-hunters who wished to increase deer numbers on their properties. The number of private supplemental feeders in Wisconsin has only been locally estimated (Wisconsin Department of Natural Resources unpubl. The United States Fish and Wildlife Service has long fed elk at the National Elk Refuge in Wyoming. However, the current Refuge manager has built strong arguments against continuing the practice (Smith 2001). For the most part, this occurred prior to the establishment of biologically defensible deer population goals. Wisconsin actively fed deer from the mid-1930s to the mid-1950s with a peak effort in 1950-51 when 1,131 tons were provided (Dahlberg and Guettinger 1956:183). Supplemental feeding and emergency feeding became blurred during this period as deer populations were being maintained at very high levels and winter losses were common. Biologists argued against feeding very early in these programs, (Bartlett 1938 in Michigan; Leopold 1943 in Wisconsin). For the most part supplemental feeding by agencies ended with the advent of better scientific data. In 1961, Congress enacted Public Law 87-152 authorizing use of surplus grains for alleviating emergency conditions for wildlife. However by 1971, Michigan found it necessary to prohibit use of surplus corn for feeding deer based on "serious nutritional problems," deer management factors, and costs (Arnold 1971). Reasons for not providing emergency feed included: 1) only a proportion of the distressed deer could be accessed for feeding; 2) of those with access, not all would be saved by feeding; and 3) the expected cost would have approached $120 per deer saved (Miller 1986). Still higher costs were reported or implied in later years by Baker and Hobbs (1985) in Colorado and Lenarz (1991) in Minnesota. A policy was established to provide technical advice on when, what, where, and how to feed deer during severe winters. This policy did not encourage deer feeding but offered guidance to citizens who chose to feed deer. There is broad consensus among deer managers in northern states that feeding should not occur except under extreme circumstances. The greatest proportion of deer killed by malnutrition in northern Wisconsin during the past 40+ years was in 1971 when winter mortality may have approached 30% (Kohn 1975). Adult does, which are the productive part of the herd, normally comprise only a small proportion of winter losses (Dahlberg and Guettinger 1956, Kubisiak, et al. Furthermore, occasional winter losses are normal and natural near the northern limit of white-tailed deer range. This legislation resulted in the passing an emergency administrative rule prohibiting baiting and feeding of deer beginning July 2002. The Joint Committee for Review of Administrative Rules authorized the extension of this emergency rule until April 1, 2003. Any rule on deer feeding will expire June 30, 2004 unless current authority is wildpro. Supporting evidence comes from observational data (Williams and Young 1992; Miller et al. Moreover prion infection of hamsters through minor wounds on the tongue was much more efficient than infection from ingestion (Bartz et al. These researchers not only demonstrate that an oral route of infection is possible, they are working toward detailed knowledge of the physiological pathways that convey infectious prions into the nervous system and other organs (Weissmann et al. Experiments with hamsters demonstrated that infectious prions can travel from the brain to the tongue along tongue-associated cranial nerves (Bartz et al. During digestion, the liver, pancreas, intestinal mucosa, and other glands secrete chemicals needed for digestion (Robbins 1983) and cells lining the inner surface of the intestine continuously die and slough off providing potential physical mechanisms for prion shedding into the intestines (others are likely). This is evidence that infectious prions are shed in the feces and saliva (Sigurdson et al. Disease course and symptoms indicate high potential for contamination of food where deer are concentrated. Once clinical symptoms start, deer enter a symptomatic phase that may last on average 1-4 months before they invariably die (Williams et al. Symptoms are subtle early on but eventually may include behaviors likely to contaminate a site with bodily fluids. This altered form, while not as virulent, was capable of producing sub-clinical or carrier-state prion infections following experimental inoculation. Shedding of infectious prions is likely progressive during the course of disease from infection to death (Williams et al. Replication and presence of infectious prions in gut-associated lymph tissue early in the incubation (Sigurdson et al.
