Current evidence suggests that ReA is a variant of septic arthritis in which the pathogen cannot be cultured diet for hemorrhagic gastritis buy lansoprazole 15 mg visa. This should direct future research efforts toward therapies targeted at eradication of the intraarticular pathogens gastritis symptoms anxiety lansoprazole 15 mg line. But before such initiatives can be taken gastritis diet ������ buy cheap lansoprazole 15 mg on-line, more reliable methods for detecting these pathogens in the joints need to be developed gastritis vomiting buy lansoprazole pills in toronto. With increased use of biologic agents for the treatment of SpA gastritis or gastroenteritis discount lansoprazole online mastercard, defined guidelines need to be formulated that balance both the risk and cost of these agents in the treatment of ReA. Recurrent episodes of acute ReA seldom occur in patients with previous Yersinia arthritis but are more frequent in patients with previous Salmonella-, Shigella-, or Chlamydia-induced arthritis. Patients with ReA triggered by urogenital infection seem to be more vulnerable to recurrent urethritides and, consequently, recurrent episodes of ReA. ReA most often affects adults between 18 and 40 years of age and presents as a monoarthritis or oligoarthritis. The knee, ankle, or one of the metatarsophalangeal joints is usually affected first. Culture of synovial fluid is the only definitive method of differentiating septic arthritis from ReA. Enthesitis, particularly Achilles tendonitis and plantar fasciitis, can be profoundly disabling in the acute phase, and in some patients, it can overshadow the inflammatory joint symptoms. Conjunctivitis is common compared with uveitis and can be mild and often goes unnoticed. It is typically anterior and unilateral and is usually responsive to topical therapy. Treatment should be instituted promptly to prevent long-term ocular complications. Patients 989 should be advised about the risk that reinfection will lead to recurrence of arthritis and about specific precautions for avoiding reinfection. The precise role of repeated infections in precipitating recurrences of ReA is not clear. Additional genital tract infections have been associated with recurrent ReA, but reinfection with enteric bacteria-even the same species that caused the initial episode-does not always lead to a recurrence of ReA. The interval between antecedent infection and ReA may extend to 4 weeks, although an interval of 1 to 2 weeks after the inciting infection is typical for the appearance of ReA. Patients with joint symptoms and other clinical features compatible with ReA therefore must be questioned closely about more remote occurrences of infection. The new onset of joint pain in the setting of diarrhea may indeed herald a case of inflammatory bowel disease with accompanying arthritis. However, infectious diarrhea caused by bacteria, parasites, or their toxins must be excluded definitively as the first priority.

Uveitis anterior is a typical extraskeletal manifestation, and psoriasis and inflammatory bowel disease are associated conditions. According to the modern concept of axial and peripheral SpA, classification criteria for axial SpA and for peripheral SpA have been developed and validated recently. Sacroiliitis on magnetic resonance images is an important imaging feature and plays a prominent role in the classification criteria for axial SpA. This subgroup of patients with so-called undifferentiated SpA became part of the SpA concept and were then classifiable by either set of criteria. Although previously the term spondyloarthropathy was used, François and colleagues proposed in the mid-1990s that the term spondyloarthritis be adopted instead, based on pathologic findings underlining the inflammatory nature. Attempts have been made to provide some guidance on how to establish a diagnosis of nr-axSpA. These include a diagnostic algorithm13 as well as a probability approach based on likelihood ratios. Back pain is the leading symptom, and many but not all patients have the symptom of inflammatory back pain, for which several definitions are available (Table 119. The presence of inflammatory back pain alone results in an estimated likelihood of the presence of axSpA of around 16%, regardless of which set of criteria for inflammatory back pain20-22 is used (see Table 119. Sausage-like digit or toe (2 points) Heel pain or other enthesopathy (2 points) Iritis (2 points) Nongonococcal urethritis within 1 mo before the onset of arthritis (1 point) 8. Past or current psoriasis and/or balanitis and/or inflammatory bowel disease (2 points) B. Sacroiliitis grade 2 or more if bilateral, grade 3 or more if unilateral (3 points) C.

The Assessment of SpondyloArthritis international Society classification criteria for peripheral spondyloarthritis and for spondyloarthritis in general. To be applied in patients with a diagnosis of axSpA, age at onset must be before 45 years of age, and chronic back pain must be present. Again, the mechanism behind this differential association is unclear but may relate to peptide binding and/or recognition characteristics. In more recent studies, this ratio has been found to be 2: 1 to 3: 1, which may be due to higher awareness of the occurrence of the disease in female patients and better access to diagnostic tests in general.

These manifestations are often regarded as incidental findings on imaging or other assessment techniques and may not require specific therapy or intervention gastritis recovery diet buy genuine lansoprazole line.

Future studies will likely elucidate the value of different modalities and help to stratify risk and the need for treatment gastritis diet ���� purchase lansoprazole without prescription. One approach that is now being evaluated is placement of implantable loop recorders that allow events to be assessed over a long period of time and with normal everyday activity gastritis symptoms images generic lansoprazole 15 mg buy. Treatment of arrhythmias depends on their pattern and hemodynamic significance, and the same approach to these clinical events in the general population is applied. Management of conduction defects follows the principles used in general cardiology and includes the use of pacing and medical approaches. These may reflect cardiac fibrosis with intrinsic conduction defects and inflammatory processes or local vascular disturbance and ischemia. This is because minor changes in rate or with imaging may not be significant, and other manifestations can be unpredictable. Cardiac involvement should be investigated systematically, and hemodynamically significant disease may be treated as outlined in the figure. Late gadolinium enhancement shows the presence of myocardial fibrosis that delays clearance of this contract medium (b). Elevated cardiac enzymes and troponin are supportive of the diagnosis but not specific. Diastolic dysfunction is one of the most frequent abnormalities and may reflect intracardiac fibrosis. Systolic impairment is generally considered to be more significant and a much more ominous prognostic event. In addition, any significant evidence of myocarditis should be treated with immunosuppression, and other approaches such as intravenous immunoglobulin or rituximab may also be considered. It is likely that intracardiac fibrosis contributes to systolic and especially diastolic dysfunction and may also contribute to arrhythmias. They are also an important cause of respiratory symptoms that include cough and dyspnea. The most frequent is cardiorespiratory and musculoskeletal deconditioning, but this must be a diagnosis of exclusion after other potentially serious and treatable causes have been excluded. For example, pulmonary fibrosis, pulmonary vascular disease, anemia, and cardiac Valvular heart disease Although it is well recognized for scleroderma patients to have valvular heart disease, it is not clear that this is an intrinsic manifestation of the disease. The most frequent is cardiorespiratory and musculoskeletal deconditioning but this must be a diagnosis of exclusion once other potentially serious and treatable causes have been excluded. Important causes to exclude are pulmonary fibrosis, pulmonary vascular disease, anemia, and cardiac dysfunction, which all contribute to symptoms of exertional breathlessness; this can be clinically challenging. A systematic and practical approach to identify potentially important and reversible factors is required. It is important to investigate new-onset symptoms that may reflect laryngeal involvement by referral and assessment in an otolaryngologic clinic. Mucosal telangiectatic lesions occur on occasion and may be a cause of epistaxis or hemoptysis. It has been extensively characterized, and management is based on the severity, progressivity, and risk of future decline. Some patients have a pattern with more extensive honeycombing reminiscent of interstitial pneumonitis (c). Recently, a less common subgroup of patients has been recognized (d) with more apical pleurally based change that resembles the newly described entity of pleuroparenchymal fibroelastosis. There is a predilection for basal and subpleural distribution, and there may be elements of homogeneous groundglass appearance that may represent fine fibrosis or inflammatory change. Thus, an operational staging system can be used that determines the extent of disease with an approximate 20% threshold for a higher risk of progression. Other patterns of lung parenchymal disease include organizing pneumonia, which is more frequent in scleroderma­myositis overlap syndromes. Other factors to consider are cases in which there is coexistent emphysematous change. Finally, an uncommon group of cases has recently been described with pleurally based fibrosis and greater involvement of the upper lobes; these are designated pleuro-parenchymal fibroelastosis. The causes of pleural or pericardial effusions are included in the associated table and figures in this chapter. These distinctions are important because they have implications for management that are discussed elsewhere in this textbook. This has been defined, and the best strategies for predicting progression are being determined, including a number of risk scores that require further validation. Pleural and pericardial disease the development of pleural and pericardial effusions occurs and always requires careful assessment. It can occur in the context of cardiac failure, fluid overload, or pulmonary arterial hypertension that leads to pericardial transudate effusion. Transudates are generally not of any hemodynamic significance in the pericardial sac; exudates are more important because they can cause diastolic collapse and tamponade. Inflammatory pleural effusions occur and require treatment with immunoinflammatory drugs but are relatively uncommon. One important point is that critical digital ischemia can be a medical emergency leading to severe pain and requiring urgent hospital based treatments. Registry data have led to subclassification of digital ulcer disease into categories of different severity. Interstitial nephritis is well recognized and may relate to medication or other factors. It has a varied frequency depending on geographic or genetic or ethnic factors and overall is seen more often in North America and Northern European patient cohorts than in Southern European or Asian patients. These clinical images demonstrate the serious sequelae of severe digital vasculopathy. Progressive digital gangrene as a consequence of significant vascular disease initially affecting the middle phalange (a) followed by both index finger and thumbs (b), resulting in autoamputation of the middle finger and subsequent loss of two other digits (c) caused by surgical amputation for severe pain and progressive vasculopathy despite maximal medical therapy. These clinical photographs show flexion deformity associated with soft tissue calcinosis over the volar aspect of left index finger (a and b) with no focal bony abnormality on plain radiography (c). Magnetic resonance image of a finger demonstrated loss of T1 marrow signal within the head of the middle phalanx of the left index finger (d) consistent with clinical suspicion of underlying osteomyelitis. Those affecting the peripheral and autonomic nervous systems are more common and may have a multifactorial basis. These require assessment and treatment along the lines of other situations with appropriate neurologic imaging, electroencephalography, and spinal fluid analysis. It is important to exclude any infective process, including opportunistic pathogens, that may cause encephalomyelitis or meningitis. The combination of accelerated hypertension and microvascular disease may explain the predilection for hypertensive encephalopathy that may be associated with headache, cognitive impairment, and seizures. Another consequence can be posterior reversible encephalopathy syndrome, which may reflect altered autoregulation of posterior cerebral circulation in the context of severe hypertension and its treatment. This should be a diagnosis of exclusion, and other causes that may coexist should be sought. It typically manifests as trigeminal neuropathy with loss of sensation in the distribution of one or more branches of the fifth cranial nerve. Sometimes this may also be seen with other cranial nerves so that some patients may present with painful glossopharyngeal neuralgia. Neuromodulatory agents can be helpful in some cases, including for the treatment of ischemic rest pain related to severe digital vasculopathy, suggesting that even in this context, there is an intrinsic neural dysfunction. Thus, some cases have small calcific deposits at the fingertips and sites of minor tissue trauma or pressure. This may resemble some cases of dermatomyositis, especially juvenile-onset disease. This may lead to calcific periarthritis with limited range of movement and severe pain. These reactivities are generally mutually exclusive and have specific immunogenetic associations. Studies suggest that vasculopathy similar to other affected organs is a key factor. Female sexual complications are most often related to perineal and vaginal trophic changes or fibrosis leading to dyspareunia. Autoantibodies that occur in other organ-specific autoimmune diseases may also be present; these include antimitochondrial antibodies and antithyroid antibodies that are associated with primary biliary cirrhosis and autoimmune thyroid disease, most often hypothyroidism, respectively. Recently, antibodies with putative agonist function have been detected against angiotensin and endothelin receptors. Finally, it is reported that antibodies against extracellular matrix components occur, and this seems to associate with severity of disease in some cases. The clinical and serologic profiles that have emerged provide a framework for subclassification, and although the clinical associations are not so strong that they can override other factors in assessment, they are useful in interpreting and pursuing profiles. Although long-term outcomes have improved and management of individual complications has progressed, there is still an overall association between outcome and clinical features and serologic reactivity. There have been studies that examine the levels of these antibodies longitudinally. These are interesting in that some associations have been observed, but these may be confusing because the levels do not predict organ complications or disease outcome.

Damage is the cumulative burden of a disease at a given time and is generally irreversible. It has face and content validity, and it is scored on a 0 (no activity) to 10 (severe activity) basis, with the greatest weight assigned to deterioration of the relevant organ system as evaluated by the patient with respect to the previous month. Alternatively, if the area rated 2 was relatively extensive, then 2 would be the recommended score for the forearm. Each site for the skin involvement (dorsum of the hand, forearm) should be scored from 0 to 3 (0 = skin that feels normal on palpation; 1 = mild skin thickness and easily able to make the skin fold between two fingers and demonstrates fine wrinkles; 2 = moderate skin thickness with difficulty in making skin folds between two fingers and unable to appreciate fine wrinkles; 3 = severe skin thickness and unable to make skin folds between two fingers. Tethered skin area, for purpose of skin scoring, should be scored as 0 because it is usually associated with atrophic skin. All results should be documented for quality control, and each trainee should receive a certificate at the end of training that should be part of the regulatory binder for the trial. Semiquantitative estimates by clinical palpation of the extent and severity of scleroderma skin changes. In all cases, the initial areas involved are peripheral and are the most severely affected. The instrument is feasible and has been shown to have acceptable reliability (test­retest and internal consistency) and validity. The instrument is sensitive to change in patient self-rated severity, and minimally important differences have been published. Dyspnea indices Patient-reported outcome measures are important for assessing the efficacy of a treatment. Baseline scores depend on ratings in three different categories: functional impairment, magnitude of the task, and magnitude of effort. These measures are useful for proof-of-concept studies but lack feasibility in large multicenter trials. A recent Delphi panel53 and separate expert consensus54 recommended the use of patient-reported outcome measures and the body mass index as core set measures. It has three scales that represent handicap associated with a reduction in mouth opening, handicap associated with sicca syndrome, and aesthetic concerns. Its sensitivity to change was shown in an intervention program that included massage of the connective tissue of the face. It includes 9 items related to upper extremity function and 2 items related to muscle weakness and lower extremity function. In Step 1, patients who develop new onset of renal crisis, new onset or worsening of lung fibrosis, new onset of pulmonary arterial hypertension, or new onset of left ventricular failure during the trial are considered as not improved and assigned a probability of improving equal to 0. For the remaining patient with complete data, step 2 involves computing the predicted probability of improving for each subject. The two groups (drug vs placebo or an active comparator) can then be compared in a 2 × 2 table using appropriate significance tests. In addition, recommendations have been published for conduct of clinical trials in scleroderma. Other novel markers include myofibroblast staining, two-gene marker (transforming growth factor-­regulated and macrophage-regulated genes),85 and gene expression profiling. Recent data suggest their utility in clinical care and predicting responders to immunosuppressive therapies. Other readily available markers are acute-phase reactants (erythrocyte sedimentation rate, C-reactive protein) that are associated with disease activity4 and predict mortality. Autoantibodies are useful for cohort enrichment,91 but their role as an outcome measure in the context of clinical trials still needs to be demonstrated.

Clinical, serologic, and genetic factors may allow individualization of serial investigations in the future. Therapies that target the immune system and vasculature have been shown to be effective in placebo-controlled studies. Effective treatments for organ-based complications are emerging, especially for scleroderma renal crisis, pulmonary interstitial fibrosis, and pulmonary hypertension. It is necessary to take a systematic approach to diagnosis and evaluation in each case to provide optimal treatment. These drugs have significantly improved the management of two of the most frequent and bothersome symptoms in scleroderma. Classically, the disease has been divided into limited and diffuse cutaneous scleroderma, but prognosis and management are more importantly affected by the stage of disease, the autoantibody subset, and the type of organ involvement. Staging and subsetting are particularly important in scleroderma because patients have different levels of risk of experiencing the different manifestations of scleroderma during the course of their illness. The disease stage-early disease, chronic stable disease, or late-stage disease-is important when considering what aspects of the disease have the potential to respond to available therapies. Autoantibody testing has been very helpful in identifying patients who are at risk of specific types of organ involvement. Patients with antitopoisomerase antibodies and nucleolar antibodies are at high risk of severe pulmonary fibrosis, which needs to be treated aggressively even though these patients may have only limited cutaneous skin disease. The past 10 years have been associated with increasing clinical trials in scleroderma. Additionally, patients can have overlap syndromes with features of other autoimmune rheumatic disorders, most commonly polymyositis and Sjögren syndrome but also rheumatoid arthritis and systemic lupus erythematosus. These overlap syndromes often present major management challenges because there may be different levels of activity among the various disease components. Clearly, not all patients require the same level of investigation or therapeutic intervention. Each patient requires an individual approach to the disease with evaluation and treatment of all appropriate problems. Identification of organ involvement requires additional testing, which, along with the stage of the disease, is helpful in determining the degree of disease activity and damage as well as the appropriate treatment.

The most characteristic feature is spontaneous pain, which usually begins in an extremity and then extends proximally and is disproportionate to the initiating event. Edema, vasomotor abnormalities (color and temperature), sudomotor abnormalities (changes in sweating), and motor and trophic changes are common but variable features. Radiographs of the affected extremity may show patchy osteoporosis, which is most marked in the juxtaarticular region. A temperature difference of at least 1°C is counted as significant and coincides with the minimum that can easily be picked up by clinical examination. Typically, the affected limb is initially warm and red and may then become mottled and intermittently warm and cool before becoming more permanently cold and cyanotic. It has been suggested that patients who report early coldness are at higher risk of going on to develop severe, late-stage disease, with infection, ulcers, chronic edema, dystonia, and myoclonus. The old term reflex sympathetic dystrophy was first used by Evans in the mid-1940s. This multiplicity of terms has been confusing, but it is now more than 20 years since complex regional pain syndrome has been accepted as a unifying descriptive name for the condition. Although the distinction between the two subtypes can be made, there is currently no evidence that it affects outcome. Some investigators have reported, in prospective studies, a cumulative incidence of around 30% after Colles or tibial fractures,9 although others reported an incidence as low as 1%. In addition to varying among patients, clinical features vary within an individual patient over time. Usually only one limb is affected, but the condition may be bilateral, or another limb may become affected at a later date. The most common causes are peripheral trauma (fracture or soft tissue injury) and orthopedic surgery. On examination, the affected site is diffusely tender, often with allodynia and hyperalgesia. Vasomotor: temperature asymmetry (at least 1°C), skin color asymmetry, skin color changes C. Although there is some doubt as to the clinical usefulness of this subdivision, it may be of help when considering studies of pathophysiology and treatment. The limb becomes cooler, and either mottled or cyanotic, with early dystrophic changes of the skin and nails. During this stage, the pain spreads proximally (in some patients, the limb may become less painful), and there are irreversible atrophic changes and contracture. The duration of each of these three stages is highly variable, and patients may exhibit features of more than one stage simultaneously. The joint space is usually preserved, although in patients who progress to late-stage disease, there may be loss of joint space and ankylosis. Inflammatory changes and microcirculatory dysfunction, possibly resulting in oxidant stress, have also been proposed as important mechanisms of tissue injury, as has immune dysfunction. A pathologic study of skeletal muscle and peripheral nerve tissue from lower limb amputations from eight patients revealed muscle changes consisting of type I fiber atrophy, an increase in lipofuscin (suggestive of free radical­mediated injury), and capillary abnormalities, with thickening or duplication of the basement membrane. In contrast to the lack of tissues from deeper structures, there is a relative wealth of data from skin biopsies. The largest study looked at biopsy specimens from 43 patients but found no difference in epidermal nerve fiber density or sweat gland nerve fiber density between patients and control participants. Although this is no longer generally accepted, there is no doubt that a select group of patients have an element of sympathetically maintained pain,24 as demonstrated by their response to sympathetic blockade. Sympathetic activity may activate both mechanoreceptors and nociceptors and could therefore contribute to the vicious cycle involving central mechanisms (see later). The affected hand is cooler: the temperature difference between the dorsum of the left hand and the dorsum of the right hand is 3. The affected knee is cooler: the temperature difference between the left and right knees is 1. As a result, until very recently, there have been very few controlled clinical trials,40,41 and those that do exist tend to be in small numbers of patients, with subjective endpoints. Many of the recommendations about treatment (including those considered here) are based on relatively low quality evidence. Many of the patients demonstrate marked pain behavior, and their distress may be compounded by the fact that, before diagnosis, their pain was thought to be "nonorganic. Pain relief has been demonstrated in a subgroup of patients, but the numbers tested remain very small at present. Initial changes are mediated by nociceptive A and C fibers, leading to sensitization and release of inflammatory neuropeptides at the dorsal horn ganglion and abnormal connections with the sympathetic nervous system, potentially resulting in sympathetically maintained pain. Dysfunction within the spinal cord can extend to adjacent levels and can cross the midline, leading to spread within a limb and contralateral symptoms. However, guanethidine regional blockade has been shown to be ineffective in meta-analyses,31 and this procedure is falling out of use, although it may continue to be a helpful intervention in a small subgroup of patients. In more advanced disease, severe pain is a barrier to rehabilitation, and physiotherapy is used in parallel with medical and psychological approaches. Graded motor imagery has also been increasingly used, but it requires a significant time commitment from the patient. A Cochrane review looking at all physiotherapy interventions found only small or low-quality trials with overall some low-quality evidence for the effectiveness of mirror therapy and graded motor imagery. Rarely, surgical sympathectomy has been advocated if a patient gains benefit from temporary sympathetic blocks, but there is very little hard evidence for this approach51 Amputation is not recommended for pain alone because phantom limb pain at the amputation stump may result, but it may be indicated, for example, if a limb is persistently infected. Even when good-quality trials have been carried out, the numbers of patients are almost invariably small. Because most patients have a significant element of neuropathic pain, a reasonable next step is to commence neuropathic analgesics such as tricyclic antidepressants and antiepileptics. For example, alendronate has been shown to reduce pain and improve function,46 but dosages used have varied widely, ranging from 35 mg per week to 40 mg/day. Lidocaine 5% patches show promise,48 if only for the way they protect allodynic skin from contact with clothing. Small studies have also shown benefit from early use of corticosteroids and use of antioxidant agents such as N-acetylcysteine and dimethylsulfoxide. However, it is a major source of pain and disability in the subgroup of patients that goes on to develop severe, late disease.

When individuals with any chronic pain state centralize their pain, they are less likely to respond to treatments. This and many other pieces of evidence suggest that these individuals have a fundamental problem with augmented pain or sensory processing. After this phenomenon is recognized, it helps determine what types of treatments will work (centrally acting analgesics, nondrug therapies) and just as important, what will not (opioids, surgery). Clinicians often encounter individuals who present with pain that they cannot adequately explain based on the degree of damage or inflammation noted in peripheral tissues. If no cause is found, these individuals are often given a diagnostic label that merely connotes that he or she has chronic pain in a region of the body without an underlying mechanistic cause. In other instances, patients may be told that there is nothing wrong with them, advised that the disorder is "all in their head," and given a label such as "somatizer" without being offered any treatment. Every subspecialist sees these same individuals, typically because they present with pain in the region of the body they specialize in. Urologists focus on their genitourinary complaints and use terms such as interstitial cystitis or chronic prostatitis, and gynecologists use terms such as vulvodynia, vulvar vestibulitis, and endometriosis. Until recently, these unexplained pain syndromes perplexed researchers, clinicians, and patients. We have come to understand that although individuals sometimes have only one of these idiopathic pain syndromes over the course of their lifetime, more commonly individuals with one of these entities will have many, and their family members also have high rates of pain in many bodily regions. Many terms have been used to describe these coaggregating syndromes and symptoms, including among others: Centralized pain disorders or central sensitization (the preferred terms for this author) Functional somatic syndromes Somatization disorders Allied spectrum conditions Chronic multisymptom illnesses Medically unexplained symptoms. Although some of these individuals have comorbid psychiatric conditions, and these are often blamed by physicians as the cause of these otherwise unexplained pains, most individuals who have these conditions do not have a definable psychiatric disorder. There is now a great deal of evidence that these syndromes are clearly different and separable from depression and anxiety and have different (yet strong) strong genetic underpinnings. Depending on the diagnostic criteria used, the prevalence ranges from 2% to 8% of the adult population. The newer criteria diagnose substantially more male patients, with the female: male ratio being about 2: 1 (instead of 9: 1 with the 1990 criteria). It occurs in relatively equal frequency in different countries, cultures, and ethnic groups; there is no evidence for this condition at increased rates in industrialized countries and cultures. A typical presentation is that of an individual who begins having regional pain conditions or somatic symptoms or syndromes earlier in life, who finally progresses to having widespread pain later in life and is given this diagnosis. The prevalence of any (regional or widespread) chronic musculoskeletal pain in the population is about 30%, so identifying any patient who has had multiple episodes of chronic pain in different areas of the body over the course of his or her lifetime is a very important clinical clue. Point of emphasis is that this is not intended to replace a physician performing a history and physical examination. The central factors can be best thought of as a volume control or pain setting on what happens to peripheral nociceptive input.
