Cognitive impairment may necessitate use of simplified pain scales or reliance on nonverbal cues to suggest pain. Verbal descriptor scales, numeric scales and faces scales have demonstrated reliability and validity in older adults. Pharmacotherapy is commonly used for persistent pain in older patients, although clinical trials often exclude patients 65 years and older. Propoxyphene has similar efficacy to aspirin and acetaminophen but should be avoided in elderly patients because of drug accumulation, neuroexcitatory effects, ataxia and dizziness. It should be reserved for those who have responded to a diagnostic sequence of local neural blockade and a stimulation trial. Adjuvant pain rehabilitation options include physical and/or occupational therapy, exercise programs directed toward the specific pain condition, ergonomic modifications, and vocational rehabilitation. Cognitive Behavioral Therapy Pain medications do not reverse tissue damage and the pain will return if medication is discontinued in patients with persistent pain. Thus, psychological therapy, including cognitive and behavioral treatments may contribute. Individual cognitive behavioral psychotherapy is insight-based with emphasis on cognitive strategies for life planning, pacing of activities, and acceptance of physical limitations and their emotional consequences. Nonpharmacologic strategies should be strongly considered in elderly patients because of safety, and can be adapted to their level of physical and cognitive function.

Behavioral Traits and Emotional Processes A number of authors opine that the current nosologic characterizations of clinical entities exhibit limits that may force a reformulation of research efforts, with a greater emphasis on normal behaviors or temperamental traits. This reformulation would have the added effect of making the evaluation of environmental (sociocultural) factors more reachable and more accurate. Studies in this new wave focus on both animal and human models of resilience, happiness, fear, shyness, altruism, or love (Alarcуn 2000). Through the use of regression models, he shows that individuals have varying degrees of susceptibility to adversity and that these variations are based, to a large degree, on psychosocial concerns. The concept of resilience exists, of course, across many or all cultures and phenomenologically entails notions such as courage, energy, altruism, resourcefulness, intellectual mastery, compassion ("learned helpfulness"), and vision. It is conceivable that specific research initiatives could be formulated that are aimed at dissecting the sociocultural and biological elements of these attributes. At the other side of the spectrum, the mostly (or purely) biological basis of heavily culturally charged behaviors such as social attachment is described as the result of hormonal variations in adult species of laboratory animals (Insel 1997). Obviously, the integrative approach advocated throughout this chapter would lead one to expect the active consideration of sociocultural (environmental) ingredients in this equation. A multidimensional interactive systemic strategy (aided by the tremendous technological progress of the past decades), rather than a unilinear approach, will make it possible to engage the findings of this type of research with those more traditionally focused on psychopathology per se. The discovery of the crucial moment and the key setting in which the cultural becomes biological and results in new normal, prepathological, or overtly pathological behaviors will add enormous consistency to the diagnostic and therapeutic tasks of mental health professionals. Special Topics Stigmatization and Racism Stigmatization is an overwhelming cultural feature in the social scene in general, and in the health care field in particular. Beyond its historical origins or its symbolic implications, (reaffirmation of beliefs, however wrong or outdated, or invocation of distorted historical assumptions), stigmatization of individuals, groups, or specific conditions effectively stops any attempt at an objective assessment of such subjects. Stigmatization leads to isolation and to the continuous reinforcement of public neglect and social rigidity toward the stigmatized (Penn and Martin 1998; C. Mental illness is one of the most stigmatized human conditions in contemporary life. Stigma creates a stereotyped approach to the examination of patients or, worse yet, contributes to prejudiced, uncritically accepted versions and explanation of behaviors. This conceptual dyad (stigma-stereotype) can result in overestimation or underestimation of a variety of conditions. In the case of minorities and immigrants, stigma car- Beyond the Funhouse Mirrors 255 ries the double jeopardy of being attached to both mental illness and ethnic prejudices. Research is needed to measure the impact of stigmatization and stereotyping on psychiatric diagnoses and, most importantly, to identify methodological and conceptual approaches to the minimization (or elimination) of their consequences (Neighbors et al. To assess their real variance in diagnostic practices would shed some light on their experiential impact on clinicians, other care providers, administrative and clerical personnel, patients, and their relatives (Weiss et al. Public education enterprises could provide the foundation of these research initiatives. Racism is the practice of racial discrimination, segregation, persecution, and domination based on a feeling of racial differences or antagonisms, particularly referred to supposed racial superiority, inferiority, or purity. Racism most usually results from a multitude of biopsychosocial factors that interact with one another in complex ways. However, racism may also be a learned behavior that has no relationship to individual psychopathology. The proponents of the model of racism as a social ill in which cultural patterns are institutionalized and internalized by socialization believe that the solution to racism lies in politics and social change, and not in the diagnostic and interpretive techniques of psychiatry (Fannon 1967; Thomas and Sillen 1972). Racism, as the systematic exaltation of assumed intrapersonal differences based on physiognomic characteristics, establishes the basis of a declared or hidden dominance-submission system in which the oppressor monopolizes the perceptions of the victim (Carter 1994; Pierce 1988, 1992; Shanklin 1998). The latter, coming from different quarters (immigrants, refugees, indigenous people, native-born ethnic minorities, or "sojourners"), may respond in a variety of ways, which would then be deemed clinical or diagnosable by clinicians trained in and by the agencies of the dominant group-the so-called ethnocentric monoculturalism of Western medicine (Kovel 1970; D. The implications of all these issues include consideration of racism as a symptom or as a diagnostic category. Considering racism as a symptom emphasizes that its underlying etiology could be multifactorial. It could be argued that this inattention has encouraged professional disregard for this extremely destructive behavior. Probably the most common form of racism originates in the psychodynamics of narcissism (Bell 1978; Kohut 1972). In this context, it could be considered a variation of narcissistic personality disorder, which may or may not reach clinical significance in terms of functional impairment for the racist individual-especially in a cultural milieu that supports such beliefs. Bell (1980) outlines the possibility that there may be two types of socially misinformed racists: those with an underlying narcissistic personality disorder in which the racist attitudes and behavior are incorporated into the narcissistic pathology, and those who are simply socially misinformed at an early age, and who with adequate education may relinquish their ignorant beliefs.

These ranges were developed since the advent of automated blood cell analysis which has allowed clinical laboratories, large and small, to screen large amounts of blood samples. However, these quantitative results must be combined with the results of an accurate history and physical examination, review of the peripheral blood smear and other, more specific, laboratory tests so that an accurate diagnosis for the cause of anemia is found. In both the inpatient and outpatient settings, anemia is one of the more commonly encountered clinical conditions affecting both children and adults. With respect to the ages at which anemia is encountered, differential diagnoses are often disparate. By and large, anemia in a child is generally because of congenital causes, whereas in adults, anemia is caused by an acquired etiology. In this chapter, we will evaluate some of the more common explanations of anemia, along with their treatments, as well as examine how laboratory measurements may facilitate the diagnosis and subsequent evaluation of therapies. Splenomegaly in children is generally caused by production of blood elements in the spleen when there is inadequate production within the marrow spaces. Examples would include the hemoglobinopathies, such as thalassemia or sickle cell disease, or erythrocyte membrane disorders, such as hereditary spherocytosis. In adults, splenomegaly may be seen in association with autoimmune hemolytic anemia or concomitant malignancy, among other diagnoses. The history will often dictate a focused examination, such as palpation of the thyroid or examination of the urine or feces for blood, in the appropriate clinical situation. Anemia is represented by a hemoglobin (Hgb) of 1315 g/dL or hematocrit (Hct) 42% in men and in women a Hgb 1113 g/dL or Hct 37%. These values vary according to ethnicity and age, but can serve as a guideline in the initial evaluation of anemia. Plasma volume may affect the measured Hgb and Hct which can be appreciated in several common scenarios. Dehydration with a decrease in plasma volume causes hemoconcentration with higher measurements of Hgb and Hct. An acute gastrointestinal bleed with rapid volume loss results in lower Hgb and Hct after plasma volume redistribution, which can take hours to develop. In addition Hgb and Hct, the complete blood count provides measures of the red blood cell count and red blood cell indices. A high reticulocyte count is consistent with rapid release of reticulocytes from the marrow into the peripheral circulation which can be seen in blood loss or hemolysis of red cells. Anemia caused by multiple etiologies may be associated with a low reticulocyte count, even in the presence of blood loss or hemolysis. While this can be due to specific viral infections, this condition frequently presents in young adults and is caused by an autoimmune phenomenon. Platelet counts may be very high (thrombocytosis) in severe iron deficiency, inflammatory conditions, or myeloproliferative disorders. Thrombocytopenia is consistent with sepsis, infiltration of the marrow, or platelet destruction. Table 40-2 provides a list of abnormal characteristics of red cells and associated etiologies. Chronic daily losses of iron occur with subclinical bleeding and normal Chapter 40 / Anemia 433 Table 40-2.

Premenopausal women, as a result of greater blood loss with menstruation, absorb 12 mg/d. Dietary nonheme iron is absorbed in the proximal duodenum under acidic conditions. Heme iron in foods, generally meats, is thought to be absorbed in a similar manner,2 although a greater proportion of dietary heme iron is absorbed than nonheme iron. Antacids and gastric acid blockers (H2-blockers and proton pump inhibitors) decrease iron absorption, whereas vitamin C enhances iron absorption. As red blood cells age, they become less deformable, and are eventually destroyed by the cells in the reticuloendothelial system.

More adult and pediatric patients die from their disease before coming to transplantation than are able to receive transplant. Currently, about 200 pediatric cardiac transplantations occur annually in North America. Survival to the point of transplant is limited primarily by patient-related factors. Long term prognosis refers to survival of both the patient and the transplanted heart. The most common threat to long-term survival is loss of graft (heart function) due to rejection, and coronary artery microvascular disease. The latter can lead to sudden death and is an indication for a second transplant in children affected by it. Periodic cardiac catheterization is routinely used (1) to obtain biopsy specimens of the right ventricular myocardium, looking for histologic signs of rejection, and in (2) coronary arteriography to screen for luminal disease. Long-term quality of life is affected by a balance of medications designed to combat rejection against the toxicity and adverse effects of these drugs (Table 11. Some patients after transplantation have relatively few episodes of clinical rejection (with symptoms). Others have only subclinical rejection that may only be detected using biopsy, but which can nevertheless damage the transplanted heart. Still others have multiple severe episodes of rejection that must be aggressively treated to maintain survival. Long-term survival and quality of life can be excellent, however, and extend for decades beyond transplantation. Some patients can eventually arrive at a point where medical therapy and its potential adverse effects are minimal (Table 11. Chapter 12 A healthy lifestyle and preventing heart disease in children Prevention for children with a normal heart Risk factors for adult-manifest cardiovascular disease Issues for children and young adults with heart disease General considerations Family counseling Additional reading and references General Diet Hyperlipidemia Obesity Tobacco Presports cardiovascular evaluation Altitude and air travel Endocarditis prevention Adults with congenital heart disease 329 329 349 349 350 370 370 370 370 371 371 371 372 372 372 In this chapter, we discuss the prevention of cardiac disease both for patients with cardiac malformations and cardiac disease acquired during childhood and for children and adolescents with a normal heart who may be at risk for the development of atherosclerotic heart disease in adulthood. We discuss the environmental and genetic factors that influence cardiac disease in these two groups of patients. Some factors are more important Pediatric Cardiology: the Essential Pocket Guide, Third Edition. We discuss factors that are generally regarded to have the greatest preventive benefit if effective modification can be achieved early in life. Tobacco Tobacco use is the single most important independent risk factor for the development of atherosclerotic cardiovascular disease that is purely environmental, and thereby potentially modifiable. Smoking and tobacco use the mechanism of adverse cardiovascular effect is related to multiple factors: (1) Endothelial cell dysfunction and injury from various toxins and oxygen free-radicals. Because of the poor rate of recovery from tobacco addiction, prevention of first use of smoking and other tobacco products among children and adolescents is the single most important means of avoiding adverse health effects in adulthood. The long-term abstinence rate among adults without physician-based intervention is less than 5% and yet with intervention it is only about 40%. Passive smoking is risky for children, so family members and household contacts should be counseled not to smoke. The cardiovascular risk is related to both dose and duration, and a safe lower limit of passive exposure has not been determined. Factors in tobacco addiction Nicotine is highly addictive and shares features common to other addictive substances: (1) Psychoactive properties substance use causes pleasurable central nervous system response. Certain individuals may be biologically predisposed to addiction; a familial tendency has been demonstrated. Patients who begin smoking as children or adolescents are more likely to continue smoking as adults. Chemical dependency on other substances is associated with increased rates of tobacco addiction. Cessation management the risk of cardiovascular disease declines after cessation and, after a number of years, may approach the risk level of those who have never smoked. The reported long-term abstinence rate of counseling, psychotherapy, and/or nicotine replacement (chewing gum, transdermal patches, nasal spray, etc.

The risk can be further reduced by taking medications that decrease airway inflammation. Most exacerbations can be prevented by the combination of avoiding triggers and taking anti-inflammatory medications. However, asthma patients should not necessarily avoid all physical exertion, because some types of activity have actually been proven to reduce symptoms. Rather, they should work in conjunction with a doctor to design a proper training regimen including the use of medication. Because asthma symptoms vary throughout the day, the respiratory system may appear normal during physical examination. Clinical signs are more likely to be present when a patient is experiencing symptoms; however, the absence of symptoms at the time of the examination does not exclude the diagnosis of asthma. Which of the following would be the best replacement for the word exacerbations in this passage? Which of the following triggers, albeit surprising, is mentioned as possibly being able to reduce the symptoms of asthma in some patients? Why might a patient with asthma have an apparently normal respiratory system during an examination by a doctor? A smoke-filled room is most likely a breeding ground for viral respiratory infections. Today, food and color additives are more strictly studied, regulated, and monitored than at any other time in history. These petitions must provide evidence that the substance is safe for the ways in which it will be used. Since 1999, indirect additives have been approved via a pre-market notification process requiring the same data as was previously required by petition. The evaluation determines an appropriate level of use that includes a built-in safety margin-a factor that allows for uncertainty about the levels of consumption that are expected to be harmless. In other words, the levels of use that gain approval are much lower than what would be expected to have any adverse effect. If new evidence suggests that a product already in use may be unsafe, or if consumption levels have changed enough to require another look, federal authorities may prohibit the use of that product or conduct further studies to determine if its use can still be considered safe. Medical waste has been a growing concern because of recent incidents of public exposure to discarded blood vials, needles (sharps), empty prescription bottles, and syringes. Medical waste can typically include general refuse, human blood and blood products, cultures and stocks of infectious agents, laboratory animal carcasses, contaminated bedding material, and pathological wastes. Chutes are limited to vertical transport, and there is some risk of exhausting contaminants into hallways if a door is left open during use. Another disadvantage of gravity chutes is that the waste container may get jammed while dropping or broken upon hitting the bottom. The main risk here is that bags may be broken or torn during transport, potentially exposing the worker to the wastes. Advantages include highspeed movement, movement in any direction, and minimal intermediate storage of untreated wastes. Off-site disposal of regulated medical wastes remains a viable option for smaller hospitals (those with fewer than 150 beds). Some preliminary on-site processing, such as compaction or hydropulping, may be necessary prior to sending the waste off-site. Compaction reduces the total volume of solid wastes, often reducing transportation and disposal costs, but it does not change the hazardous characteristics of the waste. However, compaction may not be economical if transportation and disposal costs are based on weight rather than volume. Hydropulping involves grounding the waste in the presence of an oxidizing fluid, such as hypochlorite solution. The liquid is separated from the pulp and discharged directly into the sewer, unless local limits require additional pretreatment prior to discharge. One advantage is that waste can be rendered innocuous and reduced in size within the same system. Disadvantages are the added operating burden, difficulty of controlling fugitive emission, and the difficulty of conducting microbiological tests to determine whether all organic matters and infectious organisms from the waste have been destroyed. On-site disposal is a feasible alternative for hospitals generating two tons per day or more of total solid waste.

Test findings may vary from episode to episode in the same individual, and neither is diagnostically specific. Unfortunately, none of these results have led to the identification of diagnostic markers for anxiety disorders or predictors Neuroscience Research Agenda 33 of response. As described below, genetic investigations of schizophrenia, bipolar disorder, major depressive disorder, and anxiety disorders have failed to identify vulnerability genes that are useful in predicting current and future risk of disorder. Furthermore, very few studies of the neurobiology of major psychiatric disorders have included ethnically or culturally diverse populations in their designs. At the risk of making an overly broad statement of the status of neurobiological investigations of the major psychiatric disorders noted above, it can be concluded that the field of psychiatry has thus far failed to identify a single neurobiological phenotypic marker or gene that is useful in making a diagnosis of a major psychiatric disorder or for predicting response to psychopharmacologic treatment. A primary purpose of this chapter is to review why progress has been so limited and to offer strategic insights that may lead to a more etiologically based diagnostic system. Such an accomplishment would represent a highly laudable achievement for psychiatry and would help move the specialty into the mainstream of modern medicine, where etiology and pathophysiology have replaced descriptive symptomatology as the fundamental basis for making diagnostic distinctions. For example, before the elucidation of its underlying pathophysiology, diabetes mellitus was classified as a single entity in simple descriptive terms. It was only with the understanding of the underlying pathophysiology that diabetes could be divided into two distinct and clinically meaningful entities, based on insulin deficiency versus insulin receptor sensitivity. Current classification in psychiatry therefore resembles the medicine of 50100 years ago, before the underlying pathophysiology of many disease processes was understood. Diagnostic distinctions based on etiology (as opposed to descriptive symptomatology) are more likely to lead to rational treatment selection and more valid prognostications. Despite the importance of this objective, it must be strongly stated at the outset of this discussion that it will be years-and possibly decades- before a fully explicated etiologically and pathophysiologically based classification system for psychiatry exists. Today there is only rudimentary knowledge of the genetic and nongenetic factors that cause the common psychotic, affective, anxiety, and substance use disorders that constitute the large majority of serious psychiatric disturbances. Similarly, very little is known about the molecular and cellular abnormalities that underlie the pathophysiology of psychotic, affective, anxiety, and substance use disorders, and very little specific prognostic information can be given to patients about their disorders. However, virtually all of these treatments were discovered by serendipity a half-century ago, with newer treatments representing refinements of the original mechanism of action of these agents. Thus, the last half-century has seen the development of very few truly new treatments for psychotic, affective, and anxiety disorders, and treatment of most addictions remains highly inadequate for most individuals. There are many reasons for this relative lack of progress in psychiatry compared with other medical specialties. The brain is far more complex than most other organ systems, and it remains relatively inaccessible, which makes the challenge in psychiatry considerably greater. Given the current predicament, then, how can the field develop a pathophysiologically based classification system? Despite several decades of effort, no bona fide psychiatric disease gene has yet been identified with certainty, although the field is getting closer, and new advances in genetics (including the availability of the human genome sequence) portend rapid progress. Brain imaging studies in humans promise, for the first time, to provide detailed information about molecular and cellular substrates in the brain involved in a psychiatric disorder. Although currently available imaging techniques have thus far failed to provide diagnostic tests for psychotic, affective, or anxiety disorders, it is only a matter of time before such techniques have the spatial and temporal resolution and the chemical specificity to study relevant pathophysiological mechanisms. Finally, studies of Neuroscience Research Agenda 35 brain samples obtained at autopsy should permit more detailed molecular analysis of the pathophysiology of psychiatric disorders. Over the last decade, the field has greatly increased the sophistication with which it uses postmortem tissue. There is no question that animal research has vastly expanded the knowledge of normal brain function. It has also been invaluable in identifying the initial protein targets through which most currently used pharmacotherapeutic agents. It has also been possible to develop several animal models that have outstanding predictive value in developing new medications with the same mechanism of action as, but fewer side effects than, the older agents. In the following sections of this chapter we review the current status of genetic, brain imaging, postmortem, and animal model research relevant to elucidating the pathophysiology of mental disorders. This is followed by a set of recommendations for a research agenda that will allow for the eventual adoption of a etiologically and pathophysiologically based diagnostic system. Current Status of the Genetics of Psychiatric Disorders During the past 100 years, there has been considerable interest in examining whether genes play a role in the etiology of mental disorders.

A five point Likert scale was used to measure energy/activity level and food intake. As expected, more girls and boys who were overweight had medical problems or were taking medications that are known to affect weight and/or height (p<0. In contrast, a stable, more normal energy/activity level and amount of food consumed were reported for unaffected siblings. Institute for Medical Research, (5)University of Western Australia Background: Autism is a complex neurobehavioural disorder often occurring with a variety of physical and behavioural abnormalities. This has lead to a variety of mixed and complex phenotypes which has often confounded previous genetic research. Objectives: this research aimed to harness this behavioural, biological and genetic heterogeneity as a method of creating a more powerful study, using latent class analysis to investigate the subtypes of autism. Methods: Information was collected on a cohort of 92 Autistic children (ages 4-18yrs) regarding their family histories and development using a parental report questionnaire covering pregnancy, birth, early physical and behavioural development and abnormalities, other medical conditions, diagnosis, sibling and family conditions. Current behaviour and functioning were assessed using the Vineland Adaptive Behaviour Scales, Social Responsiveness Scales, Developmental Behaviour Checklist, Childhood Communication Checklist-2. Information pertaining to their early development was collected from postnatal and early childhood records. All children were karyotyped and urine amino acid analysis used to screen for a variety of genetic disorders. Wray2, (1)Curtin University of Technology, (2)State Child Development Centre, (3)Princess Margaret Hospital, (4)Western Australian Conclusions: Focusing on conditions comorbid with autism as a clue to distinct latent classes may lead to sub-classifications of autism and thus more powerful phenotypic and genotype studies in the future. These findings were not correlated with any of the psychometric or other biological markers measured. Wray1, (1)Princess Margaret Hospital for Children, (2)Royal Darwin Hospital Background: Various biological observations in children with autism have been reported, but there is limited longitudinal data on the specificity, stability and relationship of the abnormalities with communication and social development. Objectives: To examine the stability over time and the clinical significance of certain biological markers in children with autism. On the communication subscale score, the fathers showed significantly higher scores than the control males, but the mothers did not show a significant group difference. Other subscales were not significantly different between the parents and the controls. Prior to referral major depressive disorder and obsessivecompulsive disorders were the most common psychiatric diagnoses. It has been shown to be valid, reliable, and highly sensitive and highly specific in a limited number of subjects. Two recent peer reviewed publications present the rational, a detailed description, and a clinical research application of the scale. It is now being standardized on a larger number of subjects in an international multi center study. Objectives:,To present the initial findings of the international multi center standardization study. Methods: Clinical data and scale scores are being obtained on the following types of subjects: A. Subjects with an autism spectrum disorder, 1) those diagnosed by research criteria, 2) those with a prior diagnosis by clinician of various professional disciplines, B. To date over 100 autistic spectrum and 300 non-autistic spectrum subjects have been assessed, and more will be added by the time of the presentation. Results: to be determined Conclusions: these will be based on the results of the data available for analyses on May 1, 2008, and presented at the conference. Different neurocognitive and neurobiological mechanisms may be associated with different modes of (complex) inheritance. Wu2, (1)Chiayi Christian Hospital, (2)National Chung Cheng University Background: Early diagnosis of autism in toddlers now is possible after recently vigorous investigation. Methods: We recruited 31 children aged between 24-36 months (male: female= 23: 8, with mean age=29. Conclusions: Our findings confirmed the possibility of early diagnosis of autism in children younger than 3 years old. Chi square analysis was used to compare frequencies of atypical features between groups.

Hepatocellular dysfunction (typically late in the first decade of life) may pre-date development of neurological symptoms, and early chelating therapy may prevent neurological morbidity. Neurological associations of coeliac disease, malabsorption, and inflammatory bowel disease · Can be associated with movement disorder thought to be caused, at least in part, by vitamin E malabsorption (also seen in other malabsorption states such as Crohn disease). Acute presentation: unilateral foot drop due to sacral nerve compression during colonoscopy. Encephalopathy in gastrointestinal/liver conditions · Encephalopathy and seizures are common after liver transplantation. Differential diagnosis is of non-epileptic behaviours including jittering, tremor, dyskinesias, dystonia, startle responses. These include sharp waves, occasional spikes, slowing, D brushes, A bursts, and tracй discontinuй and tracй alternant patterns. The half-life varies from 100 to 300 h in the newborn (400 h in the pre-term) falling to 60 h after 4 weeks. Further management If seizures continue despite triple therapy in adequate doses consider the following in particular. Their reliable identification requires a thorough approach systematically applied. Conditions whose potential treatability makes them particularly important to rule out are identified in blue. Therefore, it is more efficient to treat with pyridoxal phosphate if available, and define the biochemical defect subsequently in more detail if a response is seen. Discontinuation of therapy · Neonatal seizures are usually symptomatic and do not necessarily persist after the acute insult. It is associated with significant mortality (1520%) and permanent neurodevelopmental disability (25%). Hypoxicischaemic encephalopathy this is the neurological consequence of perinatal asphyxia due to lack of oxygen or perfusion to the foetus. In term infants, maternal diabetes and hypertension/toxaemia are also risk factors. Common patterns are: · Focal or multifocal cortical necrosis due to loss of perfusion in one or more vascular territories. Results in cystic encephalomalacia, ulegyria (loss of sulcal depth), or porencephaly depending on the territory, and a pyramidal pattern cerebral palsy. Results particularly in parasagittal and parietoccipital white matter loss and auditory, visuospatial and language deficits. Prolonged partial asphyxia causes diffuse cortical necrosis, epilepsy, and learning disability. Acute total asphyxia may spare cortex but cause thalamic, basal ganglia and brainstem injury, and dyskinetic cerebral palsy. Therapeutic hypothermia is achieved by either selective head, or total body cooling. Metabolic encephalopathies A large number of metabolic, toxic, infectious, and genetic abnormalities may cause a neonatal encephalopathy. The placenta usually clears toxic metabolites so the presentation may be delayed from hours to weeks post-partum (cf. These complications of pregnancy are of unknown (probably heterogeneous) aetiology; however, some of the involved children later manifest fatty acid oxidation disorders. Management of the newborn with a suspected metabolic encephalopathy · Manage cardiorespiratory depression (ventilate). Treat hyperammonaemia if a urea cycle defect suspected with Na benzoate (250 mg/kg load followed by 250 mg/kg/24 h infusion) or arginine 0. Risk factors include non-vertex presentation, large foetal head size, primiparous, or older multiparous mother, instrumental delivery or rapid/ prolonged labour. It is usually clinically silent, but may present with a catastrophic syndrome of rapid neurological deterioration with coma, flaccid tone, tonic posturing, absence of spontaneous movements or a subacute deterioration in alertness and spontaneous movement over hours to days. Embolic stroke · Placental via persistent foetal circulation allowing right to left shunting (note placental condition). Indicates limited in utero movement, which in turn may reflect: · Primary neurological cause of weakness, either central or neuromuscular in origin (for further assessment, see b p. Scoliosis and pooling of secretions with aspiration makes a myopathy (particularly nemaline rod) likely.
