These findings suggest that developmental exposure to schedule 9 medications purchase paroxetine 30mg visa dioxins may accelerate the onset of genetic expression of autoimmune pre disposition treatment diabetes type 2 generic paroxetine 10 mg mastercard. Current evidence related to treatment tendonitis generic paroxetine 40 mg without prescription pesticide autoimmunogenic potential is summarized in Table 8 symptoms ulcer order paroxetine 40mg line. Hexachlorobenzene is the most intensively studied pesticide in the context of autoimmunity, and it will therefore be addressed separately at the end of this section. There is some evidence, either in animal models or following human exposure, that several pesticides used currently or in the recent past can cause slight changes that could be interpreted as autoimmune-like effects. In some cases, the mere inclusion of observed changes as indicative of autoimmunity is even questionable, whereas in other cases, results of one study have not been confirmed by a subsequent study. Studies of autoimmunogenic potential of pesticides Active Type of Observed effects Reference ingredient exposure Aminocarb Experimental; Increase of antibody Bernier et al. The interpretation of human data is difficult, not only because only slight and subclinical effects were observed, but also because human subjects usually are exposed to a mixture of several pesti cides, thus making the identification of the role of a single ingredient very difficult. Some studies examined antinuclear or other auto antibodies in subjects exposed to pesticides in occupational settings. It is difficult to interpret studies using these measures if an appro priate comparison group is not included, given the prevalence of autoantibodies that has been reported in studies of healthy, unex posed subjects (Tan et al. Another major problem in data interpretation is the uncertainty in the extrapolation of animal find ings to humans. One such example is the interpretation of enhanced antibody response to sheep red blood cells (Burns et al. In conclusion, the body of data available shows an equivocal association between pesticide exposure and autoimmunity. However, since doubt still persists, further investigation in the field is needed. In the 1970s, such a use was prohibited in most countries, but hexachlorobenzene is still generated as a by-product of several industrial processes. Seed grain treated with hexachlorobenzene was unfortunately used as food, resulting in the poisoning of approximately 3000?5000 peo ple. Victims developed a syndrome that has been called porphyria turcica, characterized by hepatic porphyria (Cam, 1958). Other clinical features were skin lesions in sun-exposed areas, caused by photochemical activation of accumulated porphyrins (Bickers, 1987), painless arthritis, enlarged liver, spleen, lymph nodes, and thyroid, and neurological symptoms (Gocmen et al. Histology of skin biopsies showed hyperkeratosis and infiltrations of lymphocytes and macrophages. Other clinical symp toms were fever, diarrhoea, hepatomegaly, and pulmonary infil trates. Follow-up studies among 204 victims 20?30 years after the poisoning have shown that arthritis, enlarged thyroid, and neuro logical and dermatological symptoms still persisted (Cripps et al. In these workers, impaired functions of neutrophilic granulocytes and increased serum IgM and IgG levels were observed (Queiroz et al. Oral exposure of rats to hexachlorobenzene results in a dose dependent increase in the number of peripheral neutrophilic and basophilic granulocytes and monocytes and of spleen and lymph node weights. Histopathology shows increased marginal zones and follicles and extramedullary haematopoiesis in the spleen and increased numbers of high endothelial venules in mesenteric lymph nodes and popliteal lymph nodes (Vos et al. These immune effects were more obvious in Brown Norway rats than in Lewis or Wistar rats (Michielsen et 118 Chemical/Physical Agents and Autoimmunity al. Table 9 summarizes the immunotoxic effects of hexachlorobenzene in the Brown Norway rat. Immunotoxic effects of hexachlorobenzene in the Brown Norway rata Parameter Doseb References Increased spleen weight 150, 450 Michielsen et al. These macrophages are associated with experimentally induced autoimmune diseases such as rheumatoid arthritis (Dijkstra et al. This finding combined with other observations, including histological data, indicated that hexachlorobenzene induced an autoimmune-like pathology. A number of studies have focused on assessing to what extent hexachlorobenzene has a true autoimmune-based etiology. It was not until recently that it appeared that hexachlorobenzene acts probably as a sort of adjuvant chemical, by directly activating macrophages and other inflammatory cells, and that the compound does not act by creating hexachlorobenzene (or hexachlorobenzene metabolite) containing neoantigens. For instance, cyclosporin treatment delayed the development of hexachlorobenzene-induced skin lesions and prevented the increase in spleen weight. Furthermore, increases in axillary lymph node weight, lung eosinophilia, and humoral responses were prevented completely in hexachlorobenzene-exposed rats treated with cyclosporin. Results of studies with hexachlorobenzene in which macrophages were eliminated using clodronate liposomes (Ezendam, 2004) further strengthened the idea that macrophages indeed play a more important role in hexachlorobenzene-induced immune effects than T cells. Remark ably, studies performed to further assess the functional role and specificity of T cells did not provide any evidence for the presence of T cells specific for the hexachlorobenzene metabolite tetrachloro hydroquinone, nor did cytochrome P450 inhibition decrease hexa chlorobenzene-induced immune effects (Schielen et al. Moreover, hexachlorobenzene-induced immune effects could not be adoptively transferred to naive recipients. In addition, a recent study applying gene expression profiling in hexachlorobenzene-exposed 120 Chemical/Physical Agents and Autoimmunity rats provided further evidence that hexachlorobenzene induces a systemic inflammatory response, accompanied by oxidative stress and an acute-phase response (Ezendam et al. In conclusion, although hexachlorobenzene induces an auto immune-like disorder in humans and rats, neoantigen formation and direct elicitation of autoreactive T cells are probably not involved. Rather, hexachlorobenzene, by activation of inflammatory cells such as macrophages, exacerbates autoimmunity above a level at which autoimmune phenomena and systemic inflammatory responses become apparent. This cascade of reactions is depicted in Figure 2 and illustrates the complexity of the etiology of immune derange ments induced by hexachlorobenzene. Apoptosis in keratinocytes induced by ultraviolet B radiation appears to play a role in exacer bation, probably by inducing release of fragmented autoantigens (Pablos et al. In fact, occurrence of enhanced skin lesions after skin exposure to ultraviolet radiation is a diagnostic criterion. A characteristic of some autoimmune disorders is the strong geographical variation. There seems to be a clear latitude gradient in incidence of autoimmune diseases, also indicating the effect of sun exposure. This is well known for multiple sclerosis but has now also been described for diabetes mellitus type 1 and polymyositis. In this situation, ultraviolet radiation would be protective against some autoimmune disorders (McMichael & Hall, 1997; Ponsonby et al. A prime effect of ultraviolet radiation is on Langerhans cells in the skin, inducing them to leave the skin and affecting their func tionality (Schwarz et al. Thus, ultraviolet radiation induced damage in the skin plays a role in the stimulation of the autoimmune disease systemic lupus erythematosus. Besides exerting local effects in the skin, ultraviolet radiation may, through the production of circulating mediators, also cause systemic immunosuppression. This could be an explanation of the suppression of autoimmune conditions, such as multiple sclerosis and diabetes mellitus type 1, noted to occur less frequently in those countries with abundant sun. Most studies of silica and autoimmune disease have focused on occupational exposures within the traditional dusty trades, which 122 Chemical/Physical Agents and Autoimmunity include work in mines, quarries, foundries, roadway and other construction sites, masonry, sandblasting, and the production of pottery, glass, and tile. At least three recent studies of silica and autoimmune disease have shown associations with farm work (Parks et al. The condition was reversed after six months of protection from exposure to the occupational silica source. Acute high-level silica exposures may be associated with natural and other disasters, such as earthquakes, volcanic eruptions, and building collapse. Silica exposure in humans has also been associated with increased production of autoantibodies, serum immunoglobulins, and immune complexes. Studying the association of silica-related autoimmune effects in occupational settings is complicated by the fact that most auto immune diseases are fairly rare outcomes, particularly in men, who are the dominant workforce in the dusty trades. Similarly, the role of silica in autoimmune diseases is also difficult to assess in a population-based setting, given the female predominance seen in many autoimmune diseases. Occupational silica exposure may be difficult to assess in case?control studies because of the diversity of sources of exposure encountered in the general population. The association between occupational exposure to crystalline silica and rheumatoid arthritis, scleroderma, the small-vessel vascu litides. Wegener granulomatosis), and systemic lupus erythema tosus has been examined in recent reviews (Parks et al. The cohort, nested case?control, and registry linkage studies of highly exposed occupational groups.

Use additional code (F70?F79), if desired, to identify associated mental retardation. When one or more previous measurements are available, lack of weight gain in children, or evidence of weight loss in children or adults, is usually indicative of malnutrition. When only one measurement is available, the diagnosis is based on probabilities and is not defnitive without other clinical or laboratory tests. In the exceptional circumstances that no measurement of weight is available, reliance should be placed on clinical evidence. If an observed weight is below the mean value of the reference population, there is a high probability of severe malnutrition if there is an observed value situated 3 or more standard deviations below the mean value of the reference population; a high probability of moderate malnutrition for an observed value located between 2 and less than 3 standard deviations below this mean; and a high probability of mild malnutrition for an observed value located between 1 and less than 2 standard deviations below this mean. When only one measurement is available, there is a high probability of severe wasting when the observed weight is 3 or more standard deviations below the mean of the reference population. When only one measurement is available, there is a high probability of moderate protein-energy malnutrition when the observed weight is 2 or more but less than 3 standard deviations below the mean of the reference population. When only one measurement is available, there is a high probability of mild protein-energy malnutrition when the observed weight is 1 or more but less than 2 standard deviations below the mean of the reference population. The dysfunction may be primary, as in diseases, injuries, and insults that affect the brain directly and selectively; or secondary, as in systemic diseases and disorders that attack the brain only as one of the multiple organs or systems of the body that are involved. Dementia (F00?F03) is a syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, including memory, thinking, orientation, comprehension, calculation, learning capacity, language and judgement. The impairments of cognitive function are commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour or motivation. This syndrome occurs in Alzheimer disease, in cerebrovascular disease, and in other conditions primarily or secondarily affecting the brain. The disorder is usually insidious in onset and develops slowly but steadily over a period of several years. Alzheimer disease, type 2 Presenile dementia, Alzheimer type Primary degenerative dementia of the Alzheimer type, presenile onset F00. Alzheimer disease, type 1 Primary degenerative dementia of the Alzheimer type, senile onset Senile dementia, Alzheimer type F00. The cerebral cortex is usually preserved and this contrasts with the clinical picture, which may closely resemble that of dementia in Alzheimer disease. Confabulation may be a marked feature, but perception and other cognitive functions, including the intellect, are usually intact. The duration is variable and the degree of severity ranges from mild to very severe. Delusional elaboration of the hallucinations may occur, but delusions do not dominate the clinical picture; insight may be preserved. Some features suggestive of schizophrenia, such as bizarre hallucinations or thought disorder, may be present. Paranoid and paranoid-hallucinatory organic states Schizophrenia-like psychosis in epilepsy Excl. There is often a marked feeling of mental fatigue when mental tasks are attempted, and new learning is found to be subjectively diffcult, even when objectively successful. None of these symptoms is so severe that a diagnosis of either dementia (F00?F03) or delirium (F05. This diagnosis should be made only in association with a specifed physical disorder, and should not be made in the presence of any of the mental or behavioural disorders classifed to F10?F99. The disorder may precede, accompany or follow a wide variety of infections and physical disorders, both cerebral and systemic, but direct evidence of cerebral involvement is not necessarily present. Impairment of cognitive and thought functions and altered sexuality may also be part of the clinical picture. The principal difference between this disorder and the organic personality disorders is that it is reversible. Postcontusional syndrome (encephalopathy) Post-traumatic brain syndrome, nonpsychotic Excl. The third character of the code identifes the substance involved and the fourth character specifes the clinical state. The codes should be used, as required, for each substance specifed, but it should be noted that not all fourth-character codes are applicable to all substances. Identifcation of the psychoactive substance should be based on as many sources of information as possible. The main diagnosis should be classifed, whenever possible, according to the substance or class of substances that has caused or contributed most to the presenting clinical syndrome. Other diagnoses should be coded when other psychoactive substances have been taken in intoxicating amounts (common fourth character. Only in cases in which patterns of psychoactive substance-taking are chaotic and indiscriminate, or in which the contributions of different psychoactive substances are inextricably mixed, should the diagnosis of disorders resulting from multiple drug use (F19. The disturbances are directly related to the acute pharmacological effects of the substance and resolve with time, with complete recovery, except where tissue damage or other complications have arisen. Complications may include trauma, inhalation of vomitus, delirium, coma, convulsions, and other medical complications. The nature of these complications depends on the pharmacological class of substance and mode of administration. The damage may be physical (as in cases of hepatitis from the self-administration of injected psychoactive substances) or mental. The onset and course of the withdrawal state are time-limited and are related to the type of psychoactive substance and dose being used immediately before cessation or reduction of use. When organic factors are also considered to play a role in the etiology, the condition should be classifed to F05. The disorder is characterized by hallucinations (typically auditory, but often in more than one sensory modality), perceptual distortions, delusions (often of a paranoid or persecutory nature), psychomotor disturbances (excitement or stupor) and an abnormal affect, which may range from intense fear to ecstasy. The sensorium is usually clear but some degree of clouding of consciousness, though not severe confusion, may be present. Immediate recall is usually preserved and recent memory is characteristically more disturbed than remote memory. Disturbances of time sense and ordering of events are usually evident, as are diffculties in learning new material. Other cognitive functions are usually relatively well preserved and amnesic defects are out of proportion to other disturbances. Amnestic disorder, alcohol or drug-induced Korsakov psychosis or syndrome, alcohol or other psychoactive substance-induced or unspecifed Use additional code, (E51. Onset of the disorder should be directly related to the use of the psychoactive substance. Cases in which initial onset of the state occurs later than episode(s) of such substance use should be coded here only where clear and strong evidence is available to attribute the state to the residual effect of the psychoactive substance. Flashbacks may be distinguished from psychotic state partly by their episodic nature, frequently of very short duration, and by their duplication of previous alcohol or other psychoactive-substance-related experiences. It should also be used when the exact identity of some or even all the psychoactive substances being used is uncertain or unknown, since many multiple drug users themselves often do not know the details of what they are taking. Schizoaffective disorders have been retained here in spite of their controversial nature. F20 Schizophrenia the schizophrenic disorders are characterized in general by fundamental and characteristic distortions of thinking and perception, and affects that are inappropriate or blunted. Clear consciousness and intellectual capacity are usually maintained, although certain cognitive defcits may evolve in the course of time. The most important psychopathological phenomena include thought echo; thought insertion or withdrawal; thought broadcasting; delusional perception and delusions of control; infuence or passivity; hallucinatory voices commenting or discussing the patient in the third person; thought disorders; and negative symptoms. The course of schizophrenic disorders can be either continuous, or episodic with progressive or stable defcit, or there can be one or more episodes with complete or incomplete remission. The diagnosis of schizophrenia should not be made in the presence of extensive depressive or manic symptoms unless it is clear that schizophrenic symptoms antedate the affective disturbance. Nor should schizophrenia be diagnosed in the presence of overt brain disease or during states of drug intoxication or withdrawal. Similar disorders developing in the presence of epilepsy or other brain disease should be classifed under F06. Disturbances of affect, volition and speech, and catatonic symptoms, are either absent or relatively inconspicuous.

Assessment of the fetal circulation is essential in the better understanding of the pathophysiology of a wide range of pathological pregnancies and their clinical management. This book provides a comprehensive account of Doppler ultrasound in Obstetrics and will be of value to those involved in antenatal care and fetal medicine. The first chapter explains how the competent use of Doppler ultrasound techniques requires an understanding of the hemodynamics within vessels, the capabilities and limitations of Doppler ultrasound, and the different parameters which contribute to the flow display. Chapter 2 examines how ultrasound can cause thermal and mechanical effects in the body and emphasizes the responsibility of sonographers in ensuring that ultrasound is used safely. Chapter 3 describes the methodology for obtaining and analyzing flow velocity waveforms from the uterine and umbilical arteries and fetal heart, arteries and veins and explains the physiological changes that occur during pregnancy. Chapter 4 reviews the effects of impaired placental perfusion on fetal oxygenation and the hemodynamic responses to fetal hypoxemia. Chapter 5 summarizes the results of screening studies involving assessment of impedance to flow in the uterine arteries in identifying pregnancies at risk of the complications of impaired placentation, and examines the value of prophylactic treatment with low-dose aspirin, vitamins C and E and nitric oxide donors in reducing the risk for subsequent development of pre-eclampsia. The hemodynamic responses to fetal anemia and the value of Doppler ultrasound in the management of red cell isoimmunized pregnancies are described in Chapter 6. Chapter 7 outlines the relation between impedance to flow in the uterine and umbilical arteries and maternal glycemic control or maternal nephropathy and vasculopathy in diabetes mellitus. It also describes the hemodynamic consequences of fetal acidemia and hypertrophic cardiomyopathy. Chapter 8 discusses the potential value of Doppler ultrasound in the management of pregnancies with preterm prelabor amniorrhexis, both in terms of distinction between infected and non-infected cases and in the prediction of pulmonary hypoplasia. The value of uterine and umbilical artery Doppler in identifying pregnancies at risk of pre-eclampsia, intrauterine growth restriction and perinatal death in systemic lupus erythematosus and antiphospholipidsyndrome is summarized in Chapter 9. Chapter 10 reviews the Doppler findings in the placental and fetal circulations in post-term pregnancies and examines the value of Doppler in the prediction of perinatal death. Chapter 11 presents the Doppler findings in twin pregnancies and the hemodynamic changes associated with discordant fetal growth due to placental insufficiency and twin-to-twin transfusion syndrome. Chapters 12 and 13 describe the application of color Doppler in the diagnosis of cardiac and extracardiac abnormalities, respectively. As with the introduction of any new technology into routine clinical practice, it is essential that those undertaking Doppler assessment of the placental and fetal circulations are adequately trained and their results are subjected to rigorous audit. The Fetal Medicine Foundation, under the auspices of the International Society of Ultrasound in Obstetrics and Gynecology, has introduced a process of training and certification to help to establish high standards of scanning on an international basis. The Certificates of Competence in Doppler assessment of the placental and fetal circulations are awarded to those sonographers that can perform these scans to a high standard, can demonstrate a good knowledge of the indications and limitations of Doppler and can interpret the findings in both high-risk and low risk pregnancies. Color flow imaging is now commonplace and facilities such as power or energy Doppler provide new ways of imaging flow. With such versatility, it is tempting to employ the technique for ever more demanding applications and to try to measure increasingly subtle changes in the maternal and fetal circulations. To avoid misinterpretation of results, however, it is essential for the user of Doppler ultrasound to be aware of the factors that affect the Doppler signal, be it a color flow image or a Doppler sonogram. Competent use of Doppler ultrasound techniques requires an understanding of three key components: (1) the capabilities and limitations of Doppler ultrasound; (2) the different parameters which contribute to the flow display; (3) Blood flow in arteries and veins. This chapter describes how these components contribute to the quality of Doppler ultrasound images. For further reading on the subject, there are texts available covering Doppler ultrasound and blood flow theory in more detail 1-3. In ultrasound scanners, a series of pulses is transmitted to detect movement of blood. Echoes from moving scatterers exhibit slight differences in the time for the signal to be returned to the receiver (Figure 1). These differences can be measured as a direct time difference or, more usually, in terms of a phase shift from which the Doppler frequency is obtained (Figure 2). They are then processed to produce either a color flow display or a Doppler sonogram. The velocity can be calculated by the difference in transmit-to-receive time from the first pulse to the second (t2), as the scatterer moves through the beam. Doppler ultrasound measures the movement of the scatterers through the beam as a phase change in the received signal. The resulting Doppler frequency can be used to measure velocity if the beam/flow angle is known. As can be seen from Figures 1 and 2, there has to be motion in the direction of the beam; if the flow is perpendicular to the beam, there is no relative motion from pulse to pulse. The size of the Doppler signal is dependent on: (1) Blood velocity: as velocity increases, so does the Doppler frequency; (2) Ultrasound frequency: higher ultrasound frequencies give increased Doppler frequency. In the diagram, beam (A) is more aligned than (B) and produces higher-frequency Doppler signals. All types of Doppler ultrasound equipment employ filters to cut out the high amplitude, low-frequency Doppler signals resulting from tissue movement, for instance due to vessel wall motion. Filter frequency can usually be altered by the user, for example, to exclude frequencies below 50, 100 or 200 Hz. Doppler signals are obtained from all vessels in the path of the ultrasound beam (until the ultrasound beam becomes sufficiently attenuated due to depth). Continuous wave Doppler ultrasound is unable to determine the specific location of velocities within the beam and cannot be used to produce color flow images. Relatively inexpensive Doppler ultrasound systems are available which employ continuous wave probes to give Doppler output without the addition of B-mode images. Continuous wave Doppler is also used in adult cardiac scanners to investigate the high velocities in the aorta. Doppler ultrasound in general and obstetric ultrasound scanners uses pulsed wave ultrasound. Pulsed wave ultrasound is used to provide data for Doppler sonograms and color flow images. When pulses are transmitted at a given sampling frequency (known as the pulse repetition frequency), the maximum Doppler frequency? A similar effect is seen in films where wagon wheels can appear to be going backwards due to the low frame rate of the film causing misinterpretation of the movement of the wheel spokes. Figure 4 : Aliasing of color doppler imaging and Figure 5 : Reduce color gain and increase pulse artefacts of color. The time interval between sampling pulses must be sufficient for a pulse to make the return journey from the transducer to the reflector and back. If a second pulse is sent before the first is received, the receiver cannot discriminate between the reflected signal from both pulses and ambiguity in the range of the sample volume ensues. As the depth of investigation increases, the journey time of the pulse to and from the reflector is increased, reducing the pulse repetition frequency for unambiguous ranging. The longer interval between pulses allows the scanner a better chance of identifying slow flow. Aliasing will occur if low pulse repetition frequencies or velocity scales are used and high velocities are encountered (Figure 4,5 and 6). Conversely, if a high pulse repetition frequency is used to examine high velocities, low velocities may not be identified.
