Exclusion Criteria None Toolkit for Key Categories of Data Elements Incident Demographics 1. This information will always apply and be available, even if the responding unit never arrives on scene (is cancelled) or never makes patient contact b. Many systems do not require use of these fields as they can be time-consuming to enter, often too detailed. However, there is some utility in targeted use of these fields for certain situations such as stroke, spinal exams, and trauma without needing to enter all the fields in each record. Many additional factors must be considered when determining capacity including the situation, patient medical history, medical conditions, and consultation with direct medical oversight. Trauma/Injury the exam fields have many useful values for documenting trauma (deformity, bleeding, burns, etc. Use of targeted documentation of injured areas can be helpful, particularly in cases of more serious trauma. Because of the endless possible variations where this could be used, specific fields will not be defined here. Additional Vitals Options All should have a value in the Vitals Date/Time Group and can be documented individually or as an add-on to basic, standard, or full vitals a. Notes/Educational Pearls Documenting Signs and Symptoms Versus Provider Impressions 1. Signs and Symptoms should support the provider impressions, treatment guidelines and overall care given. A symptom is something the patient experiences and tells the provider; it is subjective. Provider impressions should be supported by symptoms but not be the symptoms except on rare occasions where they may be the same. This patient would have possible Symptoms of altered mental status, unconscious, respiratory distress, and respiratory failure/apnea. The narrative summarizes the incident history and care in a manner that is easily digested between caregivers. Specifically, this would include the detailed history of the scene, what the patient may have done or said or other aspects of thecal that only the provider saw, heard, or did. Most training programs provide limited instruction on how to properly document operational and clinical processes, and almost no practice. Most providers learn this skill on the job, and often proficient mentors are sparse. Some more experienced providers use it as they find telling the story from start to finish works best to organize their thoughts. A drawback to this method is that it is easy to forget to include facts because of the lack of structure. It minimizes the likelihood of forgetting information and ensures documentation is consistent between records and providers. Medications Given Showing Positive Action Using Pertinent Negatives 347 For medications that are required by protocol. If a patient had the intended therapeutic response to the medication, but a side effect that caused a clinical deterioration in another body system, then "Improved" should be chosen and the side effects documented as a complication. The patient condition deteriorated or continued to deteriorate because either the medication: i. Had a sub-therapeutic effect that was unable to stop or reverse the decline in patient condition; or iii. Was the wrong medication for the clinical situation and the therapeutic effect caused the condition to worsen. Not Applicable: the nature of the procedure has no direct expected clinical response. An effective procedure that caused an improvement in the patient condition may also have resulted in a procedure complication and the complication should be documented. In the case of worsening condition, documentation of the procedure complications may also be appropriate. Currently there are three versions of the data standard available for documentation and in which data is stored: a. Most states or systems have used this standard since its release, and the majority of most statesdata available since approximately 2016 is in this format. These fields require real data and do not accept Nil (Blank) values, Not Values, or Pertinent Negatives. However, required fields allow Nil (blank) values, Not Values, or Pertinent Negatives to be entered and submitted. Values can be left blank, which can either be an accidental or purposeful omission of data. Value fields can appropriately and purposefully be left blank if there was nothing to enter. There are 11 possible Pertinent Negative values and the available list for each field varies as appropriate to the field. The element numbering structure reflects the dataset and the text group name of the element 5. Some software systems allow the visible text name to be modified or relabeled to meet local standards or nomenclature; this feature can help improve data quality by making documentation easier for the provider. However, the technical structure of the fields has made their practical use limited as all the data is collected as a separate, self contained group, rather than as part of the procedures group. However, solutions are currently far from practical, functional, effective, or uniform in how they are being implemented or used across various systems.

If you do conceive a child afer you have fnished radiation therapy womens health 092012 order premarin 0.625mg without prescription, the fact that you had this treatment should not afect the health of the baby menopause laguna playhouse premarin 0.625 mg sale. Ways to manage For both men and women women's health new zealand magazine buy cheap premarin on line, it is important to be open and honest with your spouse or partner about your feelings and concerns breast cancer 0-9 purchase discount premarin on line, and how you prefer to be intimate while you are having radiation therapy women's health center heritage valley generic premarin 0.625 mg mastercard. Before radiation therapy starts menstruation while pregnant cheap generic premarin canada, let your doctor or nurse know if you think you might want to get pregnant afer your treatment ends. He or she can talk with you about ways to preserve your fertility, such as saving your eggs to use in the future. Your doctor or nurse can tell you about side efects you can expect and suggest ways for coping with them. If you have not yet gone through menopause, talk with your doctor or nurse about birth control and ways to keep from getting pregnant. Vaginal stenosis is a common problem for women who have radiation therapy to the pelvis. You can help by stretching your vagina using a dilator, which is a device that gently stretches the tissues of the vagina. Use a special lotion for your vagina, such as Replens, once a day to keep it moist. When you have sex, use a water or mineral oil-based lubricant, such as K-Y Jelly or Astroglide. Ask your doctor or nurse whether it is okay for you to have sex during radiation therapy. If sex is painful due to vaginal dryness, you can use a water or mineral oil-based lubricant. Before you start radiation therapy, let your doctor or nurse know if you think you might want to father children in the future. Your doctor or nurse can let you know whether you are likely to become impotent and how long it might last. If you want to father children in the future, your sperm will need to be collected before you begin treatment. Your skin in the treatment area may look as if you have a mild to severe sunburn or tan. It is important to avoid scratching, which can cause skin breakdown and infection. Skin breakdown is a problem that happens when the skin in the treatment area peels of faster than it can grow back. This problem is more common where you have skin folds, such as your buttocks, behind your ears, and under your breasts. When people get radiation therapy almost every day, their skin cells do not have enough time to grow back between treatments. How long they last Skin changes may start a few weeks afer you begin radiation therapy. Do not use heating pads, ice packs, or other hot or cold items on the treatment area. If you are using a prescribed cream for a skin problem or acne, tell your doctor or nurse before you begin radiation treatment. You can make rooms more humid by putting a bowl of water on the radiator or using a humidifer. If you use a humidifer, be sure to follow the directions about cleaning it to prevent bacteria. The sun can burn you even on cloudy days or when you are outside for just a few minutes. Wear a broad-brimmed hat, long-sleeved shirt, and long pants when you are outside. You will need to protect your skin from the sun even afer radiation therapy is over. Do not put adhesive bandages or other types of sticky tape on your skin in the treatment area. If you have radiation therapy to the rectal area, you are likely to have skin problems. Sitz baths are warm-water baths taken in a sitting position that covers only the hips and buttocks. Your treatment team will check for skin changes each time you have radiation therapy. Tese include lotions for dry or itchy skin, antibiotics to treat infection, and drugs to reduce swelling or itching. You may feel as if you have a lump in your throat or burning in your chest or throat. Why they occur Radiation to the Radiation therapy to the neck or chest can cause throat changes because shaded area may it not only kills cancer cells but also can damage the healthy cells that line cause throat your throat. How long they last You may notice throat changes two to three weeks Let your doctor or nurse afer starting radiation. Instead of eating three large meals each day, eat fve or six small meals and snacks. Let your doctor or nurse know if you notice throat changes, such as trouble swallowing, feeling as if you are choking, or coughing while eating or drinking. Your doctor can prescribe medicines that may help relieve your symptoms, such as antacids, gels that coat your throat, and painkillers. Radiation therapy can harm the healthy cells of the bladder wall and urinary tract, which can cause swelling, ulcers, and infection. How long they last Urinary and bladder problems ofen start three to fve weeks afer radiation therapy begins. Drink six to eight cups of fuids each day, enough so that your urine is clear to light yellow in color. Your doctor may prescribe antibiotics if your problems are caused by an infection. Other medicines can help you urinate, reduce burning or pain, and ease bladder spasms. Late efects are specifc to the part of your body that was treated and the doses of radiation you received. Your doctor should talk with you about late efects when you discuss your follow-up care.

The ultimate goal of the Roundtable is to increase the use of proven colorectal cancer screening tests among the entire population for whom screening is appropriate. The toolkit is intended to help organizations and communities evaluate programs designed to increase awareness and use of colorectal cancer screening, specifically those activities that are designed to increase community demand for colorectal cancer screening. In addition, the toolkit is applicable to initiatives focusing efforts on enhancing demand for colorectal cancer screening through provider education. This toolkit will provide you with: A basic understanding of evaluation strategies. This toolkit includes an overall introduction to the concepts and steps involved in evaluating colorectal cancer screening awareness programs. Throughout this toolkit, you will find examples that highlight what programs need to do during each phase of an evaluation process. In addition, a case study focusing on the evaluation of a screening program that worked to educate medical providers is included in the Appendix. Some activities are aimed at health care, such as informing providers if their patients are due for screening services. Other approaches seek to remove barriers to screening, such as interventions that reduce out-of-pocket costs or provide transportation to screening services. Group education is usually conducted by health professionals or by trained laypeople. Throughout the toolkit, these activities may be referred to as programs, initiatives, interventions, or efforts. The evidence showing the effectiveness of these interventions to increase community demand for colorectal cancer screening varies. There is strong evidence supporting small media, sufficient evidence supporting client reminders and one-on-one education, and insufficient evidence showing the effectiveness of client incentives and group education. However, all of these interventions are fairly similar in terms of how they would be evaluated. Please remember that whatever type of colorectal cancer screening awareness activity you are implementing, there is a way to evaluate it. The toolkit is not designed to evaluate mass media campaigns, as evaluating a mass media campaign requires specific skills, knowledge, and resources that are not comprehensively covered here. Evaluating mass media campaigns most often requires the assistance of experienced professionals. Some general information about evaluating mass media campaigns can be found in the Appendix. While this toolkit was developed specifically for programs working to increase colorectal cancer screening, the concepts described for evaluation can transfer to evaluation of any number of health or non-health related programs and interventions. These concepts can be successfully applied to evaluate health and human services programs and activities in a wide variety of settings, including clinics, schools, nonprofit agencies, and government programs. At its most basic level, evaluation helps you gather data to help answer these questions. We know that screening for colorectal cancer helps prevent and detect the disease early, thus increasing the likelihood of survival. For these reasons, many organizations focus resources on raising awareness about colorectal cancer and increasing individualscommitment to undergo screening. Evaluation, collecting information about how your program operates and its impact, helps you demonstrate the success of your activities. A good evaluation can also help you monitor service delivery, assess participant or community needs, and identify ways to improve. The information you collect can also build other types of support, including recruiting staff or volunteers, engaging potential collaborators, or attracting participants. By sharing your evaluation results with others, you expand the knowledge base of effective colorectal cancer screening awareness programs, essentially, multiplying the reach of your work. Understanding what your organization hopes to learn through the evaluation will help you determine the information you need to collect and the tools you will use to do so. This toolkit focuses on the following types of questions related to activities to increase colorectal cancer screening awareness and use. Below are descriptions of three sample programs that are embarking on the evaluation process, including their initial evaluation concerns. In subsequent sections of the toolkit, we will follow these programs to see how their questions were used to guide their evaluation process and how they used what they learned to enhance their programming. Their goal director expresses concern about is to increase the percentage of patients the cost of the calls and questions Every five years, the Collaborative who get screened. Are people more likely needs, assess the impact of their one education should help increase to get screened They As part of this process, Collaborative want to see data on their own patients the director follows up with members consult with core stake to justify the cost and staff time dedicated the staff making the calls, and holders including leaders within the to these one-on-one conversations. Because the education is happening like information about: How often Their discussions yield a number one-to-one, clinic staff are also interested do they successfully reach people When is the right time people read and understand their the discussion, and view staff as to call in order to reach the most materials Do the materials increase knowledge of colorectal cancer and the importance of screening Evaluation is a technical process that encourages careful planning of what you want to know and how you are going to gather the data to answer your questions. However, evaluation does not need to be overly complicated, time-consuming, or expensive. In fact, the best evaluations are often those that are kept simple and targeted to answering key program questions. Many organizations conduct evaluations to help them improve programming, using limited resources and internal staff who are not formally trained evaluators. Rushing into an evaluation without a basic understanding of the process often yields information that is difficult to use.

Many patients with chronic pain have suffered behavioral reaction to similar nociceptive stimuli this mistreatment and stand as an indictment of a poor varies from person to person and depends on a num ly trained, insecure, and disinterested segment of den ber of factors, including the signicance of the injury tistry.

This is any behavior, physical or emotional, A more complete denition is cast by the that follows pain perception. Suffering is so personal that it is difficult to tional experience associated with actual or potential quantify, evaluate, and treat. Each individual learns To understand pain better, this chapter rst looks at the application of the word through experiences what is currently known about the anatomy and phys related to injury in early life. It is unquestionably a iology of the nociceptive pathways and some of the sensation in a part of the body, but it is also always modulating inuences that modify the nociceptive unpleasant and therefore also an emotional expe input into the central nervous system. Many people report pain in the absence of various psychological and behavioral factors that inu tissue damage or any likely pathophysiological ence the perception of and reaction to pain are cause, usually this happens for psychological rea reviewed. If they regard their experience as the following summarizes what is known about the pain and if they report it in the same ways as pain basic anatomy and physiology of pain under normal caused by tissue damage, it should be accepted as physiologic conditions5: pain. Activity induced in the nociceptor and noci Acute Pain Pathways ceptive pathways by a noxious stimulus is not pain, the body has specialized neurons that respond only to which is always a psychological state, even though noxious or potentially noxious stimulation. These neu we may well appreciate that pain most often has a rons are called primary afferent nociceptors and are proximate physical cause. From here the signals are trans as any pain associated with actual nociception and mitted along specialized pathways (spinothalamic and should be treated as such. A illustrates that there are two distinct functional categories of axon: primary afferents with cell bodies in the dorsal root ganglion and sympathetic postganglionic bers with cell bodies in the sympathetic ganglion. Primary afferents include those with large-diameter myelinated (A), small diameter myelinated (Ad), and unmyelinated (C) axons. B, Electron micrograph of cross-section of a cutaneous nerve illustrating the relative size and degree of myelination of its A complement of axons. B Nonodontogenic Toothache and Chronic Head and Neck Pains 289 regions of the thalamus Figure 8-2). Bradykinin further contributes by causing nociception may occur in the thalamus and cortex, but the sympathetic nerve terminal to release a the exact location is unknown, and the contribution of prostaglandin that also stimulates the nociceptor. They are also activated by stimula and an exaggerated response to noxious stimuli (pri tion from endogenous algesic chemical substances mary hyperalgesia). Plasma extravasation, in turn, replenishes the substances at the peripheral axon injury site produces supply of inammatory chemical mediators. Sequence of events leading to pain per ception begins in the transmission system with transduction (lower left), in which a noxious stimulus produces nerve impuls es in the primary afferent nociceptor. These impulses are conducted to the spinal cord, where primary afferent noci ceptors contact central pain transmission cells, which relay the message to the thal amus either directly via the spinothalam ic tract or indirectly via the reticular for mation and the reticulothalamic pathway. From the thalamus, the message is relayed to the cerebral cortex and the hypothala mus (H). The outow is through the midbrain and medulla to the dorsal horn of the spinal cord, where it inhibits pain transmission cells, thereby reducing the intensity of perceived pain. Reproduced with permission from Pain and disability, copyright 1987 by the National Academy of Sciences. Steroids prevent the synthesis of arachidonic acid altogether, thus inhibiting both pathways of prostaglandin production. The primary afferent nociceptor synapses with a second-order pain transmission neu ron in the dorsal horn of the spinal cord where a new action potential heads toward higher brain structures (see Figure 8-2). Activation of cutaneous nociceptive C increases progressively and is enhanced with repeated bers elicits impulses that are conveyed centrally to induce pain and antidromically via axon branches (A). Neurobiol Dis repeated noxious stimulus is associated with a progres sive increase in the intensity of perceived pain. Numerous descending inhibitory systems activities (subnucleus caudalis and the substantia that originate supraspinally and strongly inuence gelatinosa of the spinal cord). How and where the brain perceives pain is ceruleus/subceruleus, among others) have also been still under investigation. The affective dimen serotonin, two of the main neurotransmitters involved sion of pain is made up of feelings of unpleasantness in the descending inhibitory pathways. Conversely, with certain types of damage to the nervous system, there may be an overreaction to pain stimuli or pain perception without nociception. Input from C toris is often felt in the left arm or the jaw, and diaphrag nociceptors enhances the response of dorsal horn pain-signaling matic pain is often perceived in the shoulder or neck. If left diameter low-threshold mechanoreceptive primary afferents (A unrecognized, it may result in a clinician telling a beta bers) respond maximally to innocuous tactile stimuli and patient that his pain is psychogenic in origin. When central sensitization is Treatments directed at the site of the pain are ineffec present, A beta bers become capable of activating central nervous tive and, if invasive, subject the patient to unnecessary system pain-signaling neurons (+), leading to touch-evoked pain risks, expense, and complications. Neuralgia: irritable nociceptors and deaf pain is dependent on a primary pain source and will ferentation. The two most popular theories are conver coolant spray is actually a popular and effective gence-projection and convergence-facilitation: modality used for pain control. Convergence-projection theory: this is the most the mechanism of referred pain from myofascial popular theory. According to Mense, the both visceral and cutaneous neurons often converge convergence-projection and convergence-facilitation onto the same second-order pain transmission neu models of referred pain do not directly apply to muscle ron in the spinal cord,21 and convergence has been pain because there is little convergence of neurons from well documented in the trigeminal brainstem deep tissues in the dorsal horn. Simons has expanded on this theory to ilar to the convergence-projection theory, except specically explain the referred pain from TrPs30 that the nociceptive input from the deeper struc Figure 8-9). The primary afferent noci this theory tries to incorporate the clinical observa ceptors of the fth cranial nerve synapse in the nucleus tion that blocking sensory input from the reference caudalis of the brainstem. The nucleus caudalis is the area, with either local anesthetic or cold, can some caudal portion of the trigeminal spinal tract nucleus times reduce the perceived pain. This is particularly and corresponds to the substantia gelatinosa of the rest true with referred pain from myofascial trigger of the spinal dorsal horn Figure 8-10). From here the nociceptive input is transmitted to the higher centers via the trigeminal lemniscus. Fibers from all three trigeminal branches are found at all levels of the nucleus, arranged with the mandibular division highest and the ophthalmic divi sion lowest. The more lateral the origin of the bers on the face, the more caudal the synapse in the nucleus Figure 8-11). According to this hypothesis, visceral afferent nociceptors (S) explain why a maxillary molar toothache may be per converge on the same pain-projection neurons as the afferents from ceived as pain in a mandibular molar on the same side the somatic structures in which the pain is perceived.

Many nociceptors from deep cervical structures synapse on the same second-order pain transmission neurons as the trigeminal nerve. This may explain why cervical pain disorders are often per ceived as facial pain or headache. As previously discussed, primary affer Pain becomes complicated and difficult to manage ent nociceptors become sensitized through the release when it is prolonged. Often the clinician is frustrated of endogenous substances caused by tissue injury. As a Nonodontogenic Toothache and Chronic Head and Neck Pains 295 Figure 8-12 Reex activation of nociceptors in self-sustaining pain. Nociceptor input acti vates sympathetic reexes, which activate or sensitize nociceptor terminals. Nociceptors induce muscle contraction, which, in some patients, activates muscle nociceptors that feed back into the same reex to sustain muscle contraction and pain. Reproduced with permission from Pain and disability, copyright 1987 by National Academy of Sciences. However, if the muscle spasm results in ischemia and accumulation Figure 8-11 the arrangement of the trigeminal nociceptive bers of the spinal trigeminal tract is signicant.

In addition, studies have shown that this type of deep musculoskeletal pain causes spasm and pain in result, normally innocuous stimuli become painful. This may partly explain the development tea makes it almost impossible to eat anything even and some of the characteristics of myofascial TrPs, to mildly spicy. Just as primary afferent noci traction (spasm) may arise as the result of a primary ceptive input may activate motoneurons, so may it also noxious stimulus.

The infection is common through the world except in the United States womens health 8 veggie burgers purchase premarin from india, Canada, Australia, Japan, and Western Europe. The infection is transmitted via the fecal-oral route, and the most common method by which infection is acquired is through consumption of contaminated food and water. A small percentage of indi viduals recover from the acute infection but become carriers and continue to shed the bacteria and therefore remain infectious. What Infected Patients Experience the incubation period for typhoid fever depends on the amount of organism ingested and the immune status of the patient, with a range from a few days to one or two months. The spectrum of illness ranges from a brief illness to an acute severe infection with central nervous system involvement and circulatory collapse. With severe 31 32 Infectious Diseases infections, patient may have altered mental status, hepatitis, meningitis (Abuekteish et al. Un treated, up to 20 percent of patients may die from the above or other complica tions. Diagnosis A probable diagnosis can be made when a patient has a clinically compatible illness associated with a confirmed outbreak. Prevention the main preventative measures for typhoid fever include avoiding potentially infectious foods and drinks and vaccination against infection. Even those vaccinated against typhoid fever should be careful about what they eat, since the vaccine is not 100 percent effective. Correlation with Gulf War Illnesses Serologic markers exist to identify patients infected, either at present or in the past, with S. Investigation of Gulf War veterans has not detected in creased antibody levels to this organism. Furthermore, in most patients this disease is either self-limited or results in severe symptoms that would precipi tate immediate treatment. This bacteria is found in most parts of the world, although it is not common in the United States, except in individuals returning from international destinations where infection is more common. Bacterial Diseases (Other Than Mycoplasma) 33 relatively short period of time, particularly with treatment, it is not a likely cause of unexplained Gulf War illnesses. The disease is present worldwide and is responsible for considerable morbidity and mortality. Tuberculosis usually exists in the form of a lung infection; however, the organism may cause disease in any organ or tissue throughout the body. The tubercule bacillus responsible for the disease is usually transmitted by the infected individual through coughing or sneezing. Although a single casual contact may transmit disease, most infections result from sustained exposures. Epidemiologic Information Tuberculosis has remained endemic in developing countries; however, it has reemerged as a major threat to both developing and industrialized countries over the last decade (Porter and Adams, 1994). What Infected Patients Experience Clinical signs and symptoms of tuberculosis vary considerably, ranging from a silent disease to severe systemic infection. Usually, secondary tuberculosis represents reactiva tion of a dormant primary infection, although exposure from exogenous sources may also occur. When the infection invades and destroys the bronchi, patients develop a productive cough, often with blood-tinged sputum and oc 34 Infectious Diseases casionally frank hemoptysis. When the disease disseminates, patients may ex perience differing symptoms and a fever without a clear origin. Diagnosis A definitive diagnosis of tuberculosis requires the identification of the tubercule bacillus. Family members and close contacts of those found to be infected should be tested and also treated if they are shown to be positive, even if the infection is an asymptomatic primary one. Correlation with Gulf War Illnesses the spectrum of disease caused by tuberculosis has been well known for cen turies. It would be almost impossible to not identify some Gulf War veterans with tuberculosis given the prevalence of the disease in the population. However, the mechanism of spread, the ability to detect the infection in most individuals through simple, routinely used skin tests, and the epidemiology of the disease all suggest that tuberculosis is not the cause of undiagnosed Gulf War illnesses. Summary Tuberculosis is a common pulmonary infection commonly caused by repeated close contact with infected individuals. However, disease reactivation occurs and the seriousness of infection is much greater in individuals with impaired immune systems. Although some Gulf War veterans will undoubtedly be found to have tuberculosis, tuber culosis does not appear to be the etiology for the many individuals with undi agnosed Gulf War illnesses. Although many of these infections are self limited, some are more problematic, causing disability and even death (Frost et al. There were a number of outbreaks of diarrhea during Operation Desert Shield (Hyams et al. Such outbreaks can be particularly disabling during periods of deployment because of both the disability they inflict on the individual and the potential for spread to other individuals. They cultured stool from 432 individuals presenting with diarrhea, cramps, vomiting, or hema tochezia. The most common bacteria were enterotoxi genic Escherichia coli and Shigella sonnei. What Infected Patients Experience Individuals may experience self-limited mild-to-moderate abdominal cramps with these infections, or disabling symptoms including diarrhea, cramps, vomiting, and hematochezia. Vomiting is present in about half of infected individuals although it rarely is responsible for major disability. The disease resolves with or without treatment; however, in the most extreme cases, fluid replacement may be necessary. Campylobacter jejuni is second only to Giardia in the frequency with which it causes waterborne diarrheal diseases in the United States. After an incubation period of from two to six days, patients develop fever, cramping, abdominal pain, and diarrhea that is at first watery but later contains blood and mucus. The incubation period is from one to two days, following which some patients develop fever, some diarrhea, and some both. Patients with dysentery experi ence small-volume frequent stools (several per hour) consisting of blood, mu cus, and pus, with abdominal cramps and tenesmus. Most patients recover over the period of up to a week, although with severe disease, they can suffer colonic perforation that can prove fatal. In addition to causing typhoid fever, infection can present as acute diarrhea or in more severe cases as septicemia, meningitis, reactive arthritis, osteomyelitis, and endo carditis. With respect to the gastroenteritis, the incubation period is generally from one to two days. Diarrhea (sometimes with the presence of blood) may be accompanied by nausea, vomiting, and abdominal cramps. Generally the ill ness is mild and self-limited, although immunosuppressed, elderly, and young patients are particularly at risk for more severe disease. Reactive arthritis is a term used to describe joint pain and inflammation follow ing exposure to bacterial infections, generally through either the gastrointesti nal tract (most commonly following exposure to Yersinia, Salmonella, or Campylobacter species) or the genitourinary tract (most commonly associated with chlamydia infections) (Ebringer and Wilson, 2000). Many Gulf War Veter ans reporting illness describe joint pain among their findings (Table 1. Typical reactive arthritis patients give a history of infection within three weeks followed by arthritis in one or several joints. Sometimes the diagnosis is problematic be cause of coexisting inflammatory processes and because in about one of four cases no infectious agent is identified (Nordstrom, 1996). Although sometimes infectious organisms may be found in the joints, laboratory findings are usually nonspecific (Beutler and Schumacher, 1997). The disease is usually self limited and resolves within six months (Nordstrom, 1996). Although some patients de velop chronic arthritis, the incidence is believed to be fairly uncommon (Nordstrom, 1996; Burmester et al. Common laboratory techniques exist to distinguish known bacterial pathogens that infect the gastrointestinal tract. Treatment and Prevention Treatment depends on identifying the infecting organism and its antibiotic re sistance pattern. In reality, most diseases are self-limited, particularly in healthy infected hosts. Once the bacterial resistance pattern is known, an ap propriate antibiotic may be selected for those patients needing more aggressive therapy. For patients with severe diarrhea, fluid and electrolyte replacement may be indicated. Because these are contagious, infectious diseases, prevention centers around isolation of infected individuals until the disease resolves. Furthermore, good hygiene contributes considerably to reducing the likelihood of infection. Correlation with Gulf War Illnesses Clearly, enteric infections occurred during the Gulf War (Hyams et al. The particular strains were frequently resistant to commonly dispensed antibiotics. Although these infections occurred in the Gulf and were clearly a major prob lem during deployment (Hyams et al. Some veterans likely suffer from chronic manifestations of reac tive arthritis given the number of individuals who served in the Gulf and the frequency of predisposing genetic risk factors. However, most patients who develop reactive arthritis achieve resolution within months. They were clearly present during service in the Persian Gulf and, in fact, accounted for a major portion of the infectious morbidity soldiers experienced during service. Therefore, enteric pathogens could not ac count for the extended chronic symptoms experienced by those with unex plained Gulf War illnesses. Healthy individuals may be carriers of the infection, and sporadic epidemiologic outbreaks continue to occur in both industrialized and developing countries. Epidemiologic Information Despite what has been learned about the biology and pathogenicity of Neisseria meningitidis, infection remains a major worldwide public health problem. The risk of death from disease de pends on a number of factors, including the prevalence of disease, the type of infection, and the sociodemographic characteristics of the area where infection occurs (Apicella, 1995). In some underdevel oped countries, fatality can exceed 50 percent among septic patients (Apicella, 1995). Irrespective of the presentation, the nasopharyngeal infection that precipitates disseminated disease usually goes unrecognized or is mistaken Bacterial Diseases (Other Than Mycoplasma) 39 for a mild respiratory infection. Although the diagnosis may be made by blood culture, the disease often resolves before the diagnosis is made. Cardiovascular involvement is also well recognized with this infection, with ac companying arrhythmias, congestive heart failure, decreased tissue perfusion, and pulmonary edema. Diagnosis Because the organism commonly colonizes the oropharynx, the mere isolation of N. Therefore, diagnosis depends on isolation of the bacteria from what is otherwise a sterile body environment. However, diagnosis is conven tionally done by serologic measures through detection of antigens from body fluids. These tests also enable demonstration of the specific serogroup responsible for infection. More re cently, use of the polymerase chain reaction has emerged as an additional pow erful diagnostic technique for meningococcal infection (Newcombe et al. In the health care setting, it is important to avoid direct contact with potentially infec tious individuals, particularly those with a respiratory infection, by adhering to droplet precautions (Bolyard et al. Treatment for meningococcal disease has dramatically altered the course of epidemics. Penicillin, administered either intravenously or intramus cularly, remains the first-line treatment. Correlation with Gulf War Illnesses Richards and colleagues (1991) confirmed four cases of N. The clinical manifestations of this disease, other than the carrier state, are generally quite dramatic, and if a significant additional population of service personnel was infected, manifestations would have been apparent and readily diagnosed.
