The triceps surae muscle will contract upon the hit treatment brachioradial pruritus cheap finax 1mg overnight delivery, and plantar flexion can be observed medicine in the middle ages discount finax amex. Plantar flexion medicine descriptions cheap finax 1 mg overnight delivery, if not seen medications 512 discount finax 1 mg without a prescription, can be felt with the examiners palm through the pushing movement of the leg medicine 666 discount finax 1mg with mastercard. Hit on your thumb with the reflex hammer and the biceps will contract as a response symptoms acid reflux cost of finax. Let the lower arm hang and strike the tendon of the triceps (the tendon is very short! Reflex response will be the extension of the elbow joint and that of the lower arm. Flexion of the forearm with sometimes the flexion of the fingers as well can be observed (the hand is slightly dorsiflexed). However in individuals with upper mo to r neuron lesions the jaw jerk reflex can be quite pronounced. Skin Reflexes (synonyms: flexor reflex, protective reflex, polysynaptic reflex) Their characteristic feature is that the recep to r and effec to r are not in the same organ. Contraction of the abdominal muscles -movement of the navel to wards the stimulated side is the response. Contraction of the abdominal muscles can be observed; the oblique abdominal muscle is contracted, and navel moves to wards the stimulated side. Investigation of Tremor Tremor is a rhythmic hyperkinesis of low amplitude and varying frequency. Generally it appears in the limbs and in head-neck muscles, and it is consisting of involuntary motions. It is caused by the preponderance of alternating innervation of agonist and antagonist muscles. A plastic thimble is put on one (generally on index finger) with a magnet on its to p. The magnet in the thimble reaches in to the coil of the tremometer; as the finger with the magnet moves the magnetic field generates a potential in the coil of the tremometer, this can be visualized on the computer screen. Investigation of Reaction Time the patient has to perform a task when receiving a signal. Reaction time is the time passed between signal onset and the completion of the task required. The instrument shows the signal according to a preset average time but at intervals which may be shorter or longer than the average. This is necessary, because reaction time may decrease due to learning if the signal appears routinely (anticipation). The signal has to be eliminated from the screen as soon as possible with the proper keyboard key. The test should be repeated ten-times, at least then the computer shows the average latency of the responses in milliseconds. Potential differences can be recorded over different regions of the brain with electrodes attached to certain standard points of the skull. In bipolar electroencephalography potential differences between two electrodes attached on the scalp are recorded (in clinical practice this is applied). In unipolar electroencephalography a differential electrode is attached on the scalp, while the indifferent electrode is placed on a neutral place. Fluctuations in the potential differences are amplified with a differential amplifier and recorded on paper. Frequency and rhythmicity of the waves, their shape and amplitude are investigated. Amplitudes are highest in the parie to -occipital region where it often forms series of waves with fluctuating amplitude in the 100 fi V range these are the so called spins. In these cases beta waves having lower amplitude with fron to -precentral dominancy can be recorded. Theta rhythm can be observed in children or in sleeping adults under normal conditions. A pathologic waveform is the so-called spike, which is the result of simultaneous excessive discharge of neurons. Short spike potentials with steep peaks are characteristic of the excited state in epilepsy. Slow waves accompanying spike-potential (spike-wave complex) are also characteristic of certain types of epileptic diseases. It is applied in the diagnosis of epilepsy and in follow up investigation of the disease, unconscious states (coma), differential diagnosis of repeated loss of consciousness, and in the diagnosis of brain death. The person is asked to identify the numbers or letters on the chart, usually starting with large rows and continuing to smaller rows until the symbols cannot be reliably identified anymore. The person to be tested is sitting 5 meters from the chart which is suspended at eye level. The patient covers an eye with the ipsilateral hand or holds an eye card over the eye. The patient is requested to read the letters, numbers or figures starting from the to p. Normal value: 1 (V = 5/5) If the person can see the characters of the size that he/she should be able to see at 5 m, the subject is said to have 5/5 visus, that is normal. If the patient can only see characters that should be seen from 50 m, than the visus is 5/50. If the patient tested cannot see the largest symbols, the chart should be placed closer. If the patient can view the to pmost symbol from 2 m, then the visual acuity will be 2/50. If visual test is unsuccessful, counting of fingers is made from a distance of 5 m. In these case the distance is given instead of visus from where the patient can count fingers shown at dark background. Refractive error correction (principle) the patient is tested with an eye chart; if deviations are found, different lenses are placed before the eyes to find the lens correcting the error. The lens set contains biconvex, biconcave and cylindrical lenses of different refractive power which can be placed in a frame. Refractive error of one eye is corrected at a time, the other is covered with the black metal slip of the spectacle. Myopia is corrected by concave (negative) lenses placed before the eye causing light rays to diverge and form sharp image at the retina. Placing convex (positive) lenses before the non-accommodating eyes cause light rays to converge and form sharp image at the retina. Detection of astigmatism If the curvature of the cornea is different along the different meridians, the image will be dis to rted. Regular astigmatism: the curvature is regular within the same meridian and the meridians of the weakest and strongest refractive power of the eye meet at a right angle. Their correction is possible with cylindrical lenses having a convex or concave surface. The cylinder acts like a plan-parallel sheet of glass plane along its axis, and it does not refract light, but its refraction is maximum perpendicularly to the axis and the transition between the two stages is not linear. In the case of astigmatism, however, concentric circles reflected on the cornea are dis to rted and shifted (like altitude lines on a map). Astigmatism b) Javal-Schiotz ophthalmometer: Refractive power and radius of curvature of the cornea can be determined with this instrument in any meridian. A chin stand is adjusted so that the eyes are at the correct level and one eye is covered. Through a telescope placed perpendicularly to the central point of cornea two images (a square-like pattern and a staircase-like figure) are projected on the cornea. Sharpen the image and by turning the ring on the telescope move the two medial figures that way that they to uch each other. At this position the curvature radius and the refrac to ry power in this meridian can be read in the smaller telescope on a scale of the device. If the position related to each other did not change the refrac to ry power and curvature radius in this meridian are the same as they were in the previous one. If the figures are shifted, try to set back the original situation (as it was 90 degrees before), and read the values on the smaller telescope. The difference between the values obtained in the original and in the new position will give the value of astigmatism. The accommodation test Accommodation is the process by which the eye changes its refractive power to maintain a clear image on an object as its distance varies. At one end of the rod there is a metal piece with two round holes; the distance of the holes should not be larger than the diameter of the pupil. When looking through the holes and fixating the closer pin (b), the pin being farther (a) will be seen double and vice versa. Mariotte blind-spot test There are spots within the normal visual space which are not perceived since light rays coming from them reach the "head of the optic nerve" the papilla where pho to recep to rs are not present. An image similar to the one represented below is held before the eyes at about a distance of 20 to 25 centimeters. Moving the picture slowly back and forth the distance is found from where the circle in the picture cannot be seen. The image of the cross (+) falls at the fovea centralis, while that of the circle on the blind spot which does not contain rods or cones, thus we cannot see it. However, it does not cause any problem in everyday life: we do not perceive a "hole" in our visual world, the visual system completes the image. Testing the light-response of the pupil Inducing the direct light response: one of the eyes is covered, while the other one is illuminated with a medium or weak light; the pupil will constrict. Consensual reaction: Light shown in one eye will cause a constriction of the contralateral pupil. The light reaction of the pupils can be tested even in our own eyes with the help of a pupilloscope. We place our chin on the chin-stand (B), through the hole (C) we can view the concentric circles (E) on the board and try to fixate on the middle. The left pupil will constrict and due to the consensual light reaction so will the right pupil. Because the light beams from the periphery are closed out we shall see 2-3 circles less when the light is on. If the light is turned off both pupils will extend, and with our right eye we shall see all of the concentric circles again. This is not a very reliable test, however, it is very simple, does not need instrumentation and can be performed on poorly educated subjects or on persons who can not cooperate well. There are some marks, lines, numbers or letters different from the background color of the plate. The color of the mark to be recognized is readily distinguished by persons of normal color vision, whereas persons with color blindness will not find the mark. The colors are not homogeneous, they consist of spots, disks, or wavy lines, thereby the effect of contrast can be ruled out. Testing the size of the visual field (perimetry) Perimeter 58 the visual field is the a area of space viewed at with motionless eyes. The purpose of the test is to define the space viewed by the patient, the recognition of a possible sco to ma, its localization and determination of its extent. His right eye is covered and asked to look in to our right eye with his/her left eye, while we cover our left eye. With the index finger we move from the periphery to the center from several directions and the patient gives a signal when he sees our finger. Visual field of the left (a) and the right (b) eye this method is not sophisticated, it can detect a large sco to ma only. The extent of visual field can be tested with a small blinking light along each meridian or a moving paper sign with this test. The chin of the patient is placed on the stand in a position that the eye tested is at the level of the central point of the sphere and can be fixed with the eye tested. A white paper sheet (or paper of the desired color in case of color perimetry) is fixed in the groves of the arch. Next the marker is moved slowly in the same meridian between the two extreme points to test any sco to mas. The test is repeated rotating the arch of the perimeter in to different meridians of each eye. By joining the recorded points the outermost borders of the visual field can be recorded. Compare the results obtained with the physiological visual field (indicated in the diagram with dotted line). Deviations from the normal values can be given indicating the meridians where they were detected. Visual fields of both eyes are 100-120 degrees vertically, 180 degrees horizontally when the eyes are stationary; with moving eyes it is 200 degrees vertically and 260 degrees horizontally. The size of the visual field is different for different colors; it is the largest for white followed by blue and red and the smallest one is for green. Ophthalmoscopy the fundus of the eye as seen with an ophthalmoscope the test is based on the fact that the light that is projected through the pupil is not fully absorbed but a part of it is reflected back; light rays will exit from the eye at the same angle as they entered. Under normal circumstances the pupil seems to be black because our head prevents the entry of those very light rays that would be reflected back to wards our eyes. If we use light of proper intensity and illuminate the eye of a person the light that is reflected will be sufficient for the examiner to view the back of the eye, the fundus.

The text was initially written in the early 20th century medicine nelly buy 1 mg finax with amex, as a pamphlet for New England health oficials medicine reminder app buy generic finax 1 mg on-line, by Dr medications related to the female reproductive system cheap finax uk. Its 30 pages contained disease control measures for the 38 communicable diseases that were then reportable in the United States medicine q10 purchase finax 1mg with visa. It covers over 140 diseases and groups of diseases of importance to communicable disease hunters and researchers symptoms 7 days after embryo transfer order finax with a visa. Heymann and his team at the World Health Organization have assembled an impressive group of experts from around the world to serve as reviewers symptoms for diabetes order finax 1mg with amex, authors, and edi to rs. I also want to thank the many men and women who work silently behind the scenes and on occasion have given their lives to contain the threat of infectious disease. The microbial agents that cause them are dynamic, resilient, and well adapted to exploit opportunities for change and spread. Their public health significance in terms of human suffering, deaths, and disability is compounded by the considerable to ll they take on economic growth and development. Communicable diseases kill more than 14 million people each year, mainly in the developing world. Large populations living in remote areas of the developing world are at risk of disabling diseases, such as poliomyelitis, leprosy, lymphatic filariasis, and onchocerciasis. The huge number of permanently disabled persons reduces the work force and further undermines the financial security of already impoverished families and communities, who already take on the onus of care and economic support. For all these reasons, concern about the impact of communicable diseases has increased, with some encouraging results. Also noted are those labora to ry tests most commonly used to identify or confirm the etiological agent. Occurrence provides information on where the disease is known to occur and in which population groups it is most likely to occur. Mode of transmission describes the mechanisms by which the infectious agent is spread to humans. Disaster implications: given a disaster, indicates the likelihood that the disease might constitute a major problem if preventive actions are not initiated. Measures in case of deliberate use of biological agents to cause harm (formerly bioterrorism measures): for selected diseases, this new section provides information and guidelines for public health workers who may be confronted with a threatened or actual act of deliberate use with a specific infectious disease agent. The specific disease may not be included in the list of diseases oficially reportable, or it may be of unknown etiology if it is newly recognized or emerging. National guidelines and legislation indicate which type of oubtreak must be reported, who is responsible for reporting, the format for reporting, and how case reports are to be entered in to and forwarded within the national system. In general, outbreak reporting is required by the most rapid means of communication available. Collective outbreak reports including the num ber of cases and deaths may be requested on a daily or weekly basis for diseases with outbreak potential such as infiuenza. National health authorities may also require reports of infectious diseases caused by agents that may be used deliberately. Class 3: Selectively reportable in recognized endemic areas Many national health authorities do not require case reporting of diseases of this class. Examples of diseases in this class are scrub typhus, schis to somiasis and fasciolopsiasis. Class 5: Oficial report not ordinarily justifiable Diseases in this class occur sporadically or are uncommon, often not directly transmissible from person to person (chromoblas to mycosis), or of an epidemiological nature that offers no practical measures for control (common cold). Steps in an outbreak response are systematic and based on epidemiological evidence despite the fact that public and political reaction, urgency and the local situation may make this dificult. The following steps provide minimal guidance for responding to out breaks and are sometimes done concurrently: Verify the diagnosis Confirm the existence of an outbreak Identify affected persons and their characteristics Record case his to ries Identify additional cases Define and investigate population at risk Formulate a hypothesis as to source and spread of the outbreak Contain the outbreak Manage cases Implement control measures to prevent spread Conduct ongoing disease surveillance Prepare a report. For surveillance and control purposes, investiga to rs must agree on a common surveillance case definition (this may not always correspond to the clinical case definition). Confirm the existence of an outbreak Some diseases, although long endemic in an area, remain unrecognized; new cases may come to light, for instance, when new treatments attract patients who previously relied on traditional medicines. For endemic diseases, an outbreak is said to have begun when incidence rises above the normally expected level. For diseases showing a cyclical or seasonal variation, the average incidence rates over particular weeks or months of previous years, or average high or low levels over a period of years, may be used as baselines. Usually this information includes name, age, sex, occupation, place of residence, recent movements, details of symp to ms (including dates and time of onset) and dates of previous immunization against childhood or other diseases. If the incubation period is known, informa tion on possible source contacts may be sought. This information is best recorded on specially prepared record forms called line lists. Identify additional cases Initial notification of an outbreak may come from a clinic or hospital; enquiries in health centres, dispensaries and villages in the area may reveal other cases, sometimes with a range of additional symp to ms. Formulate a hypothesis as to source and spread of the outbreak Determine why the outbreak occurred when it did and what set the stage for its occurrence. For foodborne outbreaks it is neces sary to determine source, vehicle, predisposing circumstances and portal of entry. Contain the outbreak the key to effective containment of an outbreak is a coordinated investigation and response involving health workers including clinicians, epidemiologists, microbiologists, health educa to rs and the public health authority. The best way to ensure coordination may be to establish an outbreak containment committee early in the outbreak. Manage cases Health workers, including clinicians, must assume responsibility for treatment of diagnosed cases. Outbreaks such as poliomyeli this may leave in their wake patients with an immediate need for physio therapy and rehabilitation; timely organization of these services will lessen the impact of the outbreak. However, from the very beginning xxx of the investigation the investigative team must attempt to limit the spread and the occurrence of new cases. Whatever the urgency of the control measures they must also be explained to the community at risk. If supplies of vaccine or drugs are limited, it may be necessary to identify the groups at highest risk initial for control measures. Once these urgent measures have been put in place, it is necessary to initiate more perma nent ones such as health education, improved water supply, vec to r control or improved food hygiene. Sources of information for surveillance include: i) notifications of illness by health workers, community chiefs, employers, school teachers, heads of families; ii) certification of deaths by medical authorities; iii) data from other sources such as public health labora to ries, en to mological and veterinary services. It may be necessary to maintain estimates of the immune status of the population when immunization is part of control activities, by relating the amount of vaccine used to the estimated number of persons at risk, including newborns. Reports may be: i) a popular account for the general public so that they understand the nature of the outbreak and what is required of them to prevent spread or recurrence; ii) an account for planners in the Ministry of Health/local authority so as to ensure that the necessary administrative steps are taken to prevent recurrence: iii) a scientific report for publication in a medical journal or epidermiological bulletin (reports of recent outbreaks are valuable aids when teaching staff about outbreak control). Such verification requires more labora to ry facilities than are available in the field, and is often not completed until long after the outbreak has been contained. The response will of necessity involve the intelligence com munity and law enforcement agencies as well as public health services, and possibly the Defence Ministry as well, especially if the event is considered of non-domestic origin. Dificulties in communication and approaches may arise, since these disciplines do not usually work to gether. The event and associated hoaxes caused unprecedented demands on public health labora to ry services, and several nations had to recruit private labora to ries to deal with the overfiow. If the agent is widely dispersed and/or easily transmissible, a surge capacity may be required to accommodate large numbers of patients, and systems must be available for the rapid mobilization and distribution of medicines or vaccines according to the agent released. In the event that the agent is transmissible, additional capacity will be required for contact tracing and active surveillance. International threat analysis xxxii considers that deliberate use of biological agents to cause harm is a real threat and that it can occur at any time; however, such risk analysis is not generally considered a public health function. According to national intelligence and defence services, there is evi dence that national and international networks have engineered biological agents for use as weapons, in some instances with suggestions of attempts to increase pathogenicity and to develop delivery mechanisms for their deliberate use. The agent used will determine whether there is a risk of person- to -person transmis sion after the initial and subsequent attacks; information on this risk is covered in more detail under specific disease agents. This has led some analysts to regard a strong public health infrastructure, with rapid and effective detection and response mechanisms for naturally occurring infectious diseases of outbreak potential, as the only reasonable means of responding to the threat of deliberately caused outbreaks of infectious disease. Adequate background information on the natural behaviour of infectious diseases will facilitate recognition of an unusual event and help determine whether suspicions of a deliberate use should be investigated. Preparedness for deliberate use also requires mechanisms that can be immediately called in to action to enhance communication and collabora tion among the public health authorities, the intelligence community, law enforcement agencies and national defence systems as need may arise. Preparedness should draw on existing plans for responding to large-scale natural disasters, such as earthquakes or industrial or transportation accidents, in which health care facilities are required to deal with a surge of casualties and emergency admissions. One of the most dificult issues for the public health system is to decide whether preparedness should include s to ckpiling of drugs, vaccines and equipment. A single test is recommended in populations with a prevalence rate above 10%; lower prevalence levels require a minimum of 2 different tests for reliability. Selection of tests depends on fac to rs such as accuracy and local operational characteristics. Viral load tests are now available and serve as an additional marker of disease progression and response to treatment. China and India, more recently infected, remain of major concern epidemiologically. While the virus has occasionally been found in saliva, tears, urine and bronchial secretions, transmission after contact with these secretions has not been reported. The major interaction identified so far is with Mycobacterium tuberculosis infection. In other situations, latex condoms must be used correctly every time a person has vaginal, anal or oral sex. There is some evidence that exclusive breastfeeding is associated with lower transmission rates than partial breastfeeding. Organizations that collect plasma, blood or other body fiuids or organs should inform potential donors of this recommendation and test all do nors. Health care workers should wear latex gloves, eye protection and other personal protective equipment in order to avoid contact with blood or with fiuids. Where nominal reporting is not the rule, care must be taken to protect patient confidentiality. Prophylactic use of oral tri methoprim-sufamethoxazole, with aerosolized pentami dine as a less effective backup, is recommended to prevent P. A successful treatment is not a cure, although it results in suppression of viral replication. Once the decision to initiate antiretroviral treatment has been made, treatment should be aggressive with the goal of maximal viral suppression. Health care organizations should have pro to cols that promote and facilitate prompt access to postexposure care and report ing of exposures. Clinical findings and culture allow distinction between actinomycosis and actino myce to ma, which are very different diseases. Men and women of all races and age groups may be affected; frequency is maximal between 15 and 35 years; the M:F ratio is approxi mately 2:1. Cases in cattle, horses and other animals are caused by other Actinomyces species. In the normal oral cavity, the organisms grow as saprophytes in dental plaque and in to nsillar crypts, without apparent penetration or cellular response in adjacent tissues. From the oral cavity, the organism may be aspirated in to the lung or introduced in to jaw tissues through injury, extraction of teeth or mucosal abrasion. Preventive measures: Maintenance of oral hygiene, particu larly removal of accumulating dental plaque, will reduce risk of oral infection. The parasite may act as a commensal or invade the tissues and give rise to intestinal or extraintestinal disease. Intestinal disease varies from acute or fulminating dysentery with fever, chills and bloody or mucoid diarrhea (amoebic dysentery), to mild abdominal discomfort with diarrhea containing blood or mucus, alternat ing with periods of constipation or remission. Ulceration of the skin, usually in the perianal region, occurs rarely by direct extension from intestinal lesions or amoebic liver ab scesses; penile lesions may occur in active homosexuals. Amoebic colitis is often confused with forms of infiamma to ry bowel disease such as ulcerative colitis; care should be taken to distinguish the two since corticosteroids may exacerbate amoebic colitis. Conversely, the presence of amoebae may be misinterpreted as the cause of diarrhea in a person whose primary enteric illness is the result of another condition. Diagnosis is by microscopic demonstration of trophozoites or cysts in fresh or suitably preserved fecal specimens, smears of aspirates or scrapings obtained by proc to scopy or aspirates of abscesses or sections of tissue. S to ol antigen detection tests have recently become available, but do not distinguish pathogenic from nonpathogenic organisms; assays specific for Entamoeba his to lytica are also available. In isolates, 9 potentially pathogenic and 13 nonpathogenic zymodemes (classified as E.

Page 10 of 64 While promising symptoms 9f anxiety trusted finax 1mg, many of these efforts are limited in scope and scale medicine games order generic finax on line, and lack coordination medications dictionary buy discount finax line. The Task Force is pleased to present this final report and recommendations for consideration by the Secretary of Health and all Pennsylvanians symptoms yellow eyes order finax 1mg mastercard. Frequently Used Terms While Lyme disease is arguably the most commonly occurring and widely-recognized tick-borne disease medicine werx finax 1mg low cost, it is by no means the only one medications 1 gram purchase finax 1mg mastercard. Antibiotic prophylaxis: Antimicrobial therapy following a known exposure to a bacterial pathogen that is given to prevent the development of disease. Babesiosis: Cause by microscopic parasites that infect red blood cells and are spread by certain ticks. Although many people who are infected with Babesia do not have symp to ms, effective treatment is available for those who do. Bar to nellosis: A disease or infection caused by bacteria of the genus Bar to nella which primarily cause infection of nonhuman animals and are transmitted via insect vec to rs (fleas, lice, flies, etc. The bacteria attack red blood cells and may cause severe anemia and high fever followed by skin eruption. Three species are well documented as human pathogens with as many as 7 others known to be possible human pathogens based on the current evidence. A Bar to nella infection in humans can manifest with little or no symp to ms or as severe as ongoing febrile illness and more rarely, produce serious complications like endocarditis and encephalitis. The organism is transmitted to humans by tick vec to rs, primarily Ixodes scapularis (more commonly known as a deer tick). Borrelia miyamo to i: A bacterial infection has recently been described as a cause of illness in the U. Clinically Diagnosed Lyme Disease Cases: Diagnoses based on medical his to ry, symp to ms, physical examination. Page 12 of 64 Ehrlichiosis is transmitted to humans by the lone star tick (Ambylomma americanum), found primarily in the southcentral and eastern U. Epidemiology: Epidemiology is the study of the distribution and determinants of health-related states or events in 12 specified populations, and the application of this study to the control of health problems. Hyperendemic: Exhibiting a high and continued incidence; used chiefly of human diseases. This tick is widely distributed in the Northeastern and upper Midwestern United States. Lyme disease is transmitted by the blacklegged tick (Ixodes scapularis) in the northeastern U. Powassan disease is transmitted by the blacklegged tick (Ixodes scapularis) and the groundhog tick (Ixodes cookei). Cases have been reported primarily from northeastern states and the Great Lakes region. Q-fever is usually spread when dust contaminated by dried placental material, birth fluids, urine, or feces from infected animals becomes airborne and is inhaled. Tick-borne transmission also has been documented and the bacterium that causes Q-fever has been identified in Dermacen to r spp. Seroconversion: the change of a serologic test from negative to positive, indicating the development of antibodies in response to infection or immunization. These infections are caused by bacteria from the Page 13 of 64 Rickettsiaceae family and spread by ticks. Each of these tick-borne rickettsial infections has distinct epidemiologic characteristics (type of tick(s) that spreads the bacteria, geographic distribution) and target different types of cells in the body during infection. The bacteria that cause tularemia may also be transmitted after bare skin contacts infected animal tissues or contaminated soil or dust particles are inhaled. If this first step is negative, no further testing of the specimen is recommended. The incidence rate of all of the diseases discussed in these recommendations has continued to increase. They have also been expanding in geographic range, and new human tick-borne pathogens continue to be recognized. These trends result in an ever larger number of persons requiring treatment, placing a greater financial impact on the healthcare system and individual patients and ultimately, a 14 greater burden on society. It is widely agreed that the best way to avoid such outcomes is through prevention actions. Prevention of disease is far preferable to treating the short and long-term consequences once they occur. Whether this is because they simply do not work or because they have been underused or ineffectively applied is far less clear, and clearly better options are needed. School property represents a highly utilized public space that could have a significant and rapid impact on prevention awareness. This information could be used to support further research as well as investments in school-based health. A critical way to prevent infection is to reduce the likelihood of exposure by reducing tick populations, and by adopting a combination of multiple prevention strategies. The Institute of Medicine formed a working group including schools and public properties, and various other symposiums have been convened to assess and share best practices in reducing tick populations in public properties. The above strategies, especially in combination, were shown to greatly reduce risks to the staff and public. The Agency is providing all staff with tick-removal kits, web-based information on prevention measures, and repellents, which include Off, Deet, Permetherin, and Natrapel, a natural organic repellent. Other measures that are being explored include using lighter colored clothing, chemically treated clothing, and use of repellents inside vehicles. Use of antibiotics before or at the time of specimen collection may also produce false negative results. Be aware that there are multiple schools of thought across the medical community regarding diagnosis and treatment of Tick-borne diseases. It is well agreed upon that testing is inaccurate in early Lyme disease (within 30 days of starting symp to ms). Current state findings regarding physician practices and the patient experience point specifically to the need for education: 16 * Many common symp to ms go unrecognized, even the mostly widely recognized bulls-eye rash 17 * Physician practices vary significantly in both diagnosis and treatment 18 * Patients experience significant delays in diagnosis and treatment 19 * Patient outcomes are less than satisfac to ry Studies have found that some tick-borne disease patients experience delays in diagnosis and a portion remain sick for long periods of time. There is a critical need for healthcare education and reform to reduce such delays, and to improve the validity and effectiveness of diagnostic and treatment options available to patients. Thus access to medical care for Lyme disease is improved, and the burden of illness is reduced. Education would bring the healthcare community up to date with rapidly evolving science, the associated risks of exposure, what to do about bites and early stages of disease, and especially how to prevent the progression of disease to later stages with more incapacitating outcomes. The goal is to catch disease earlier, and to provide a better understanding of disease processes and treatment options, to ultimately improve patient outcomes. Lastly, awareness and education of the general public, insurers, and governmental agencies would address prevention approaches, general awareness, and improve access to early and appropriate treatment, all of which are identified in the intent of Act 83. This section outlines specific recommendations regarding awareness and education, fundamental to Act 83. Accessibility and appeal of information will help more people understand the risks as well as practical strategies to reduce exposure. It also provided basic guidelines to help employees identify and properly remove ticks, as well as when to seek treatment. Further educational and awareness efforts will be developed and data will be collected to ensure effectiveness. An online clearinghouse will spur the creation of important materials and resources, promote consistency in future communications, and eliminate redundancies in agency efforts. A cross-sec to r symposium or tech-based event, such as a data jam or hackathon, will allow for the exchange of ideas, feedback, and information. Finally, funding is critical to the success of all Task Force recommendations and can support vital research, education, surveillance, prevention, and treatment programs. To build awareness and increase student engagement around issues related to tick-borne diseases, the Task Force recommends considering partnerships with national organizations focused on these diseases to create voluntary, incentivized, school-based campaigns and contests. Up front assessment will ensure that programs are targeted and cost-effective; post-program measurement will demonstrate results and target ongoing programs. Patient choice is important in considering treatment options with proven safety and effectiveness. Information provided should empower health care providers to weigh the pros and cons of different treatment options, in cases with and without a definitive diagnosis, different patient presentations, and the pediatric aspect of treatment. By providing information through a variety of channels, healthcare professionals can choose the venue that is most appropriate and appealing for them, increasing engagement with the to pic. Targeting primary care providers, especially for high-risk areas or populations, will help professionals better understand when to refer to a specialist and who to refer to for ongoing management, if necessary. Page 28 of 64 Ultimately, all information created with health care professionals in mind should emphasize how to approach weighing risks vs. Information collected through ecological and disease surveillance enables areas and risk groups with high rates of infection to be identified, which can help direct prevention efforts and prioritize how public health resources are distributed. It will also inform members of the medical and healthcare community on the specific types of tick-related infections that are being encountered most frequently in a particular county or geographical region of our commonwealth. Ecological surveillance provides essential information on the presence of: a) specific tick vec to rs in specified geographic areas, b) the pathogenic organisms that they carry, and c) animal disease reservoirs and other animal hosts upon which the ticks feed. Ecological surveillance data along with an understanding of fac to rs that impact transmission. Surveillance data along with observational epidemiologic studies can provide a better understanding of the burden and severity of specific tick-borne diseases among Pennsylvania residents. Lastly, it is important to note that case classification definitions for disease surveillance purposes are not intended for clinical diagnosis, especially since case identification and investigation for surveillance are most often performed retrospectively after treatment decisions have been made. Lyme disease and tick-borne rickettsial infections (Anaplasmosis, Ehrlichiosis, and Rocky Mountain spotted fever) are already included on the notifiable disease list for surveillance along with tularemia and Q fever which may be transmitted by ticks or zoonotic exposures. Given these emerging threats, there is an urgent need to develop new and innovative diagnostic technologies that would enable rapid lab based testing systems to identify the specific pathogens or pathogens associated with the tick bite. Such innovative technologies would enable physician to utilize available treatments that are known to effectively target the specific pathogen without the significant delays associated with current serologically based diagnostic methodologies. The comprehensive survey should include species distribution, density, phenology, and pathogen prevalence and load. The role of animal hosts and reservoirs on tick distribution and pathogen prevalence should also be assessed, as well as the temporal, spatial and life stage exposure risk, geographic and seasonal hotspots in Pennsylvania. This information will arm the public with more information that will lead to better tick avoidance strategies (see Prevention recommendations regarding pro to col and funding strategy for high-risk areas. In addition to the basic gathering of data, a web based site should be funded and designed to provide physicians and the public with the most up- to -date information about tick-borne disease in Pennsylvania. There should be contact information on the site that is specifically for physicians/health care providers as well a link for the general public. A resource guide on the distribution and infectivity of ticks should be provided by county and presented to licensed physicians. Observation studies may include: 1) use of prevention practices and risk fac to rs for tick-borne disease; 2) self-reported tick-borne disease illness; and 3) long-term patient outcomes. This information is often difficult to obtain during routine surveillance given the high volume of case reports. Further, observational studies can allow for risk fac to rs and behaviors to be measured among residents regardless of their tick-borne disease his to ry along with providing information to inform tick-borne disease education and prevention activities. Widely available diagnostic tests for Lyme disease and tick-borne rickettsial infections rely on the development of pathogen-specific antibodies which takes time. These advisories also may include information based on the biomedical literature on the pathogenesis of infection, the spectrum of infection from the proportion of asymp to matic infections if applicable to severe disease and complications, updated treatment recommendations, and prevention measures. The current reporting system for human surveillance is overwhelmed by the number of reported Lyme disease cases each year. Veterinarians throughout the commonwealth should be encouraged to participate in these existing programs, since they serve as an important adjunct to human and ecologic surveillance.

Conflicts of Interest Gordon Blackhouse has received funding for conducting educational workshops. The simultaneous and widespread use of both tests has raised concerns about their potential overuse, particularly if they provide little valuable information regarding patient management and outcomes. Accordingly, research questions (see section 2) were developed to explore the added value associated with performing both tests rather than one. Published literature was identified by searching the following bibliographic databases: PubMed, and the Cochrane Library (2014, Issue 6) via Wiley. The main search concepts were erythrocyte sedimentation rate and C-reactive protein. Where possible, retrieval was limited to the human population, items published between January 2004 and June 11, 2014, and the English language. Edi to rials, comments, letters, and newspaper articles were excluded from the search results. Regular alerts were established to update the search until the publication of the final report. Regular search updates were performed on databases that do not provide alert services. To complement the initial search, a second search of the same databases was performed on January 15, 2015. Retrieval was limited to items published between January 1980 and January 15, 2015 and the English language. Google and other Internet search engines were used to search for additional Web-based materials. These searches were supplemented by reviewing the bibliographies of key papers and through contacts with appropriate experts and industry. Two reviewers independently screened the titles and abstracts for relevance using a predefined checklist (Appendix 2). Full texts of relevant titles and abstracts were retrieved, and assessed by two independent reviewers to make inclusion and exclusion decisions, using explicit predetermined criteria (Appendix 3). Discrepancies between the reviewers were resolved by consensus, consulting a third reviewer when necessary. The to ol also addresses concerns about the applicability of tests and provides signalling questions to help identify potential biases. Data from all included studies were extracted in to predefined data abstraction forms (Appendix 5). Relevant data were directly extracted from the text or tables by two independent reviewers. The data extraction forms were piloted by the reviewers, a priori, and a calibration exercise using data from 25% of studies was undertaken to ensure consistency between the reviewers. Direct and indirect comparisons the analysis of the diagnostic test performance involves two steps. When there was more than one study with the same disease condition, the results of multiple studies of the same test for a particular condition. Since no more than four similar studies (in terms of tests, conditions, and outcomes) were identified by the review, a fixed effects analysis 14 was used, with a simple sum of the elements in the two-by-two tables. The indirect comparison was estimated with the publicly available indirect treatment comparison software 15. The Bucher method allows indirect comparisons between relative test performances if the patient populations are similar. Therefore, this review conducted an indirect comparison across studies with the same disease condition. By conducting pairwise estimates, this review obtained results that reflect relative values for sensitivity, specificity, etc. Because the relative values are ratios of values from each test, the results can be greater than 1. Missing data For studies that did not report all of the statistical parameters and confidence intervals, wherever possible, the missing parameters and confidence intervals were derived from available information. Specifically, not all studies reported the elements of the two-by-two contingency tables, i. Unfortunately, these latter values are required for meta-analysis of diagnostic accuracy studies. To derive the missing information, reviewers relied on the assumption that the elements of the two-by-two table can be recreated using available information, as described in the following paragraphs. In most cases, sensitivity and specificity were provided without confidence intervals. Occasionally, other outcome measures such as predictive values were provided, again without confidence intervals, and this information was used to verify the unique two-by-two table. Specifically, for a given study size, there is one unique set of two-by-two contingency table values that will create the sensitivity and specificity. The unique two-by-two contingency table will also create other diagnostic test performance estimates such as predictive values or likelihood ratios. If these latter values were reported in the published papers, reviewers could confirm that the unique two-by-two contingency table created these latter values. When confidence intervals were provided, reviewers assumed they were derived through binomial approximation methods, which is the most common statistical distribution. From the available estimate and confidence interval, reviewers iteratively estimated the unique number of true-positives and false-negatives to recreate the confidence interval. After a similar exercise for 17 non-disease cases, the numbers of true-negatives and false-positives were derived. With these derived two-by-two table estimates, the estimates and confidence intervals were recreated to ensure approximate consistency, as well as being verified with other estimates such as positive predictive values. To minimize such discrepancies, the mean estimated values of the two-by-two estimates were used. Of those, 41 did not meet the eligibility criteria and were excluded, and one reported cost-effectiveness data, leaving 18-25 10 articles for the clinical review. Four of the included articles reported on the diagnostic performance of the study tests in diagnosing periprosthetic 18,21,23,25 infections after to tal hip or knee arthroplasty procedures in adults. Of these, five 18,21-23,27 used a prospective data collection approach, while three reviewed medical charts 19,20,25 retrospectively. However, it was not clear how the data from the control groups were used in the analysis. Sample sizes varied across the 24 19 studies, ranging from 63 to 764 participants, mostly derived from individual academic 22 hospitals. One study enrolled patients from multiple referral centres, while the remaining seven studies were conducted in a single medical centre. The definition of a combined test was not clear in the remaining 22,23,27 three studies. However, a closer examination of the results of two of these studies revealed that what had been considered a combined test in both studies had a higher sensitivity 23,22 and lower specificity than either of the individual tests. Three of the studies were 24,28 rated as having a high risk of selection bias because they used a case-control design, or 22,24 18-21,23,25,27 applied extensive exclusion criteria. Another 20 study was considered to be at a high risk of bias for index test and reference standard domains, due to not using pre-specified cut-off points for index tests. It was unclear if the 19 reference standard used in one of the studies could correctly classify the target condition. In this study, positive giant cell artery biopsy results were used for confirmation of diagnosis of giant cell arteritis. The authors noted in their discussion that the possibility of misclassification of biopsy-negative giant cell arteritis patients as disease-free could not be precluded in their study. Three studies were assessed as being at unclear risk of bias for the flow and timing 22,24,27 22 domain. However, their description of study methodology implied that chest X-ray and bacteriologic examination had not 28 been performed for all study participants. One study, which used retrospectively collected data on a combination of clinical symp to ms, referral his to ry, and antibiotic therapy to verify the diagnosis of pediatric bone and joint infections, was classified as raising some levels of applicability concern in terms of reference standard test. It was also unclear if the exclusion of culture 22 (reference standard)-negative patients in the Paakkonen et al. In addition, the generalizability of study results could be limited due to unusually 18 21 high prevalence of disease in studies by Costa et al. Appendix 11 provides details of the study index tests, the reference standard used for the confirmation of diagnosis, the relative frequency of disease-positive individuals diagnosed by the reference standard, and the number of truly or falsely diagnosed patients by the index tests of interest. Appendix 12 shows the diagnostic performance measures for the tests of interest when compared with the reference standard employed in each study (direct comparisons). Two of these studies used a single criterion of a positive synovial fluid 18,23 bacterial culture as the reference standard, while the other two employed similar multiple criteria diagnostic to ols to confirm the diagnosis (see Appendix 11 for details). The prevalence 18 of periprosthetic infection was considerably higher in the studies by Costa et al. The results of direct pooled analyses of the tests of interest versus the reference standard employed in each study are provided in Table 4. Pediatric orthopedic infections Data on the diagnostic performance of the study tests in pediatric orthopedic infections were 20,22 available from two studies. However, due to the paucity of data and significant differences between the two studies in terms of study population, index test cut-off points, and the reference standard, pooled analysis was not conducted for this subgroup of included studies. A positive bone or joint bacterial culture was the main diagnostic criteria (reference standard) used in this study. However, patients were excluded if they had a negative culture, which allowed only sensitivity values to be reported. However, the overall accuracy of the three types of tests demonstrated little variation (between 0. However, data were not pooled due to clinical and methodological heterogeneity in the studies. The two studies used different study designs and thresholds to 28 define positive and negative test results. Descriptions of the results from these two studies are discussed in the following paragraphs. The study included patients with suspected giant cell arteritis for whom temporal artery biopsy had been requested. Lack of data reported on proportions of truly of falsely diagnosed cases did not allow for any calculations of sensitivity, specificity, and other diagnostic performance metrics. However, due to heterogeneity in terms of study design and the diagnostic thresholds used for a positive test, the relative diagnostic measures are described separately for these two studies (see Tables 8 and 9 for details). Based on the checklist, there were some deficiencies in the study design, as neither the perspective of the analysis nor justification of the form of economic evaluation were explicitly stated. The authors did not undertake any sensitivity analysis as part of analysis of results. The cost per useful event can be converted from 2002 Japanese Yen to 2015 Canadian dollars by applying the his to rical 31 2002 exchange rate exchange rate (1fi = C$0. Because the only identified published economic study was conducted in Japan, its generalizability to the Canadian setting is questionable. Therefore, the cost-effectiveness outcome for this definition was the incremental cost per false-positive avoided.
