Development of mammalian cultured neurons following exposure to anticonvulsant drugs. Febrile seizures are now recognized as a relatively benign, age-dependent epilepsy syndrome and the most prevalent form of seizure in early life. This definition is useful because it emphasizes age specificity and the absence of underlying brain abnormalities. It also implies that febrile seizures are not true epilepsy, because affected individuals are not predisposed to recurrent afebrile episodes. Intracranial infection may not be readily apparent, especially in very young infants. Although few medical practitioners advocate extensive testing in a healthy child with a brief nonfocal febrile seizure, an infant or child in febrile status epilepticus requires immediate medical attention. Familiarity with the clinical manifestations and long-term prognosis of febrile seizures is essential in caring for affected individuals. Epidemiologic studies have been especially useful in identifying features of the seizure or the patient that involve adverse consequences. Understanding these factors forms the basis of proper seizure management and family counseling. Coexistence of febrile seizures and epilepsy increases the risk for both disorders in siblings (8). Temporal lobe seizures are more likely to begin early but remit permanently if a firstdegree relative has experienced a febrile seizure (11). A single gene is held responsible, because the siblings of patients with temporal lobe and febrile seizures have a similar incidence of febrile seizures alone. The incidence of febrile seizures also varies according to geographic region and race. Parents and siblings of Asian children are at considerably higher risk for febrile seizures than are Western families. The difference in frequency of febrile seizures in Asian compared with European or North American families suggests a strong, genetically determined population effect (12).

This effect has been proposed for heparin, administered systemically during dialysis, with resultant activation of lipoprotein lipase (17). Hepatic blood inflow by the portal vein, hepatocellular mass, and functional capacity primarily determine the effects of liver disease on drug handling. At least five categories of liver disease affect drug disposition: (i) chronic liver disease; (ii) acute hepatitis; (iii) druginduced hepatotoxicity; (iv) cholestasis; and (v) hepatic infiltrative/neoplastic disease. In addition, medications must be classified not only by protein binding but also by the capacity of the liver to extract drug as blood flows through the organ: flow limited, capacity limited with high protein binding, and capacity limited with low protein binding (19). Flow-limited drugs have high extraction rates, and clearance is limited primarily by blood flow. Most anticonvulsants are capacity-limited drugs, as their extraction ratios are low (0. The rate of metabolism of capacity-limited drugs depends on the concentration of free drug at hepatic enzyme receptor sites and thus on the extent of protein binding. Capacity-limited, binding-sensitive drugs, such as phenytoin, valproic acid, and carbamazepine, are greater than 85% bound to plasma proteins at therapeutic concentrations; therefore, alterations in plasma protein concentration and binding characteristics can significantly alter their hepatic clearance (23,24). Capacity-limited, bindinginsensitive drugs, such as ethosuximide, have a low affinity for plasma protein (usually less than 30% at therapeutic concentrations), and clearance is only minimally affected by changes in protein binding. The following model, combining the principles of intrinsic metabolic capacity and blood flow, has been proposed (25): Clh = Q * Fb * Clint Q + Fb * Clint stant. The extraction ratio (E) may be derived by dividing hepatic blood flow into total hepatic clearance (27): Cl = E Q When combined hepatic and renal clearance occurs, clearances are additive. Although hypoalbuminemia is frequently a feature of liver disease, drug binding to plasma proteins may be decreased even without measurable changes in albumin concentration (Table 47. Mechanisms similar to those causing decreased protein binding in renal insufficiency have been suggested (28,29). Because intrinsic clearance varies with the type and duration of liver disease, the effects of changes in protein binding in capacity-limited, binding-sensitive drugs are complex. If hepatic disease lowers binding without changing intrinsic clearance, total drug concentration will ultimately fall because the rate of metabolism of these drugs depends on the free fraction. If liver disease reduces intrinsic clearance, total drug concentration may remain the same or increase as the free concentration increases. This can result in enhanced response or toxic effects at lower than expected drug levels and may explain the increased incidence of adverse reactions to medications such as valproic acid in liver disease (30). Capacity-limited, binding-insensitive drugs can be considered relatively pure indicators of intrinsic clearance. However, tissue binding to substances such as ligandin may contribute where Clh is the volume of blood cleared by the liver per unit time, Q is total hepatic blood flow, Fb is the fraction of drug bound to protein and cells, and Clint is the intrinsic metabolic clearance (23,24,26). High Low Unknown High Contraindicated Considerable Unknown Unknown Dosage adjustment Unnecessary or slight reduction Unnecessary or slight reduction Unnecessary or slight reduction Unknown Unknown Reduction Unnecessary Reduction Reduction Contraindicated Reduction Reduction/Contraindicatedb Reduction T, Reduced; -, unchanged; c, increased. The effect of liver disease on the content and function of such binding proteins is poorly understood. Tissue binding can be affected by secondary pathologic changes of liver disease, such as alterations in tissue and plasma pH level (24,31­33) or by ascites (34,35). Because of various types of drugs and stages of liver disease, as well as interindividual variation, predicting changes in drug kinetics in patients with hepatic insufficiency remains difficult. Studies have identified additional discrepancies between observed changes and those suggested by pharmacokinetic predictions (12,23,36). Another variable is the potential for autoinduction of microsomal enzymes after long-term drug administration. Phenobarbital and carbamazepine and their active metabolites have this potential, with resultant temporal variability in drug levels and efficacy, increased complexity of drug interactions, and the potential increased risk of liver dysfunction. For concentrations less than 10 mg/L, elimination is exponential; at high levels, it is dose dependent (40). Effects of Renal Disease Phenytoin is the most extensively studied anticonvulsant in renal dysfunction. Uremic plasma has lower binding capacity for phenytoin than plasma in healthy subjects, with unbound fractions as high as 30%, compared with the usual 10% to 15% (28,41­43).

The relief device and trap must be supported so that they are not dislodged or thrown due the thrust resulting from sudden venting. In the case of a system protected by a spring-loaded relief device, the maximum operating pressure should be from 5 to 25% lower than the rated working pressure, depending on the type of safety valve and the importance of leak-free operation. Vent pressure-relief devices that may discharge toxic, corrosive, flammable, or otherwise hazardous or noxious materials in a safe and environmentally acceptable manner such as scrubbing or diluting with nonflammable streams. Do not install valves or other shutoff devices between pressure-relief devices and the equipment they are to protect. Similarly, do not install shutoff valves downstream of the relief device and take care to ensure that the relief vent is not blocked or restricted. Tubing and piping downstream of such devices must be at least the same diameter as the fitting on the vent side of the relief device. Only qualified persons should perform maintenance work on pressure-relief devices. Gas manifolds, compressors, and other sources of high-pressure gas used to supply an apparatus, and which can be isolated from the apparatus by valving, should also be protected by a properly designed pressure-relief device. Generally, select a gauge with a range that is double the working pressure of the system. A pressure gauge is normally a weak point in any Copyright © National Academy of Sciences. Prudent Practices in the Laboratory: Handling and Management of Chemical Hazards, Updated Version 168 the event of breakage. Mass flowmeters are available that can replace rotameters in desired applications. Only use materials that are appropriately rated or recommended for that particular service. Tygon and similar plastic tubing have quite limited applications in pressure work. These materials can be used for hydrocarbons and most aqueous solutions at room temperature and moderate pressure. However, loose tubing under pressure can cause physical damage by its own whipping action. Details of permissible operating conditions must be obtained from the manufacturer. Because of their very large coefficients of thermal expansion, some polymers have a tendency to expand greatly on heating and to contract on cooling. This behavior can create a hazard in equipment subjected to very low temperatures or to alternating low and high temperatures. Plastic tubing may also disrupt electrical grounding and thus present a static electricity hazard. The use of plastic tubing with flammable gases or liquids is not recommended if grounding is an issue. The materials of construction (metal, elastomer, and plastic components) must be compatible with the gases and solvents being used. Ball valves are preferred over needle valves because their status (on/ off) can be determined by quick visual inspection. Use metering or needle valves only when careful flow control is important to the operation. Micrometers can sometimes be used with needle valves to allow quick determination of the status. Consider their use especially if large quantities or large cylinders of these gases are in use. Make sure the monitor is properly rated for the intended purpose as some detectors are subject to interference by other gases.

For best results, be sure that the engineers, trained laboratory personnel, and the vendors understand how the chemical hoods are intended to be used. Prudent Practices in the Laboratory: Handling and Management of Chemical Hazards, Updated Version 232 · the nature of the materials that must be controlled compared to the filter media provided with the recirculating hood. Individuals using recirculating hoods need training on the use and limitations of the recirculating hood. Each ductless chemical hood should have signage explaining the limitations, how to detect whether the filter media are working, and the filter maintenance schedule. Spills will be caught in the cupsink by the standpipe for later cleanup and disposal. A lip on the cupsink could be used as an alternative to a standpipe to prevent spills from getting into the sink. The word "walk-in" is a misnomer; one should never actually walk into a chemical hood when it is operating and contains hazardous chemicals. If the personnel are required to enter the hood during operations where hazardous chemicals are present, 9. The sash can be a vertical-rising or a horizontal-sliding type or a combination of the two. Normally, the work surface is dished or has a raised lip around the periphery to contain spills. Sinks in chemical hoods are not recommended because they encourage laboratory personnel to dispose of chemicals in them. It may include respirators, chemical splash goggles, rubber gloves, boots, suits, and self-contained breathing apparatus. They are usually accessed through a horizontal sliding sash from the front and rear. Because their configuration precludes the use of baffles and airfoils, they may not provide a suitable face velocity distribution across their many openings. A ventilated enclosure is any site-fabricated chemical hood designed primarily for containing processes such as scale-up or pilot plant equipment. Most do not have baffles or airfoils, and most designs have not had the rigorous testing and design refinement that conventional mass-produced chemical hoods enjoy. Working at the opening of the devices, even when the plane of the opening has not been broken, may expose personnel to higher concentrations of hazardous materials than if a conventional hood were used. These materials become pyrophoric when they dry or dehydrate (see also Chapter 6, section 6. Special water spray systems are used to wash down all interior surfaces of the hood, duct, fan, and stack, and special drains are necessary to handle the effluent from the washdown. Water spray heads are usually installed in the top, behind the baffles, and in the interior. The water spray should be turned on whenever perchloric acid is being heated in the chemical fume hood. The ductwork should be fabricated of plastic, glass, or stainless steel and fitted with spray heads approximately every 10 ft on vertical runs and at each change in direction. The fan and stack should be fabricated of plastic, fiberglass, or stainless steel. Welded or flanged and gasketed fittings to provide airtight and watertight connections are recommended. Several safety supply companies offer portable disposable glovebag containment chambers with sufficient space to conduct the work and then dispose of them in accordance with applicable nuclear regulatory standards. Polypropylene hoods burn easily, melt quickly, and may become fully involved in a fire. There are fireretardant polypropylene and other thermoplastics available, but they cost more. A drain and waste valve on the water supply piping that allows it to drain when not in use is helpful.

Primidone Primidone (2-deoxyphenobarbital), structurally related to phenobarbital, is not significantly bound to plasma proteins. It is partially converted by the liver to the active forms phenobarbital and phenylethylmalonamide. Effects of Renal Disease Although little information is available on the use of primidone in renal disease, accumulation with resultant toxicity has been reported, presumably from delayed renal excretion and prolongation of the phenylethylmalonamide half-life. In one report (63), phenylethylmalonamide levels were proportionately higher than those of primidone or phenobarbital and thus were hypothesized to be responsible for clinical toxicity. Another patient showed evidence of intoxication, with high phenylethylmalonamide levels and moderate elevation of phenobarbital in association with renal failure (64). Effects of Liver Disease Valproic acid disposition studies in patients with alcoholic cirrhosis and those recovering from acute viral hepatitis (70) noted variably decreased protein binding (from 88. Total drug plasma clearance remained unimpaired in both groups, but free drug clearance decreased in cirrhotic patients. Reduced protein binding also increased the entrance of free valproic acid into blood cells and lowered metabolism by limiting substrate concentration. Therefore, liver diseases studied appeared to result in reduced metabolic capacity for valproic acid that was compensated for by decreased protein binding. However, another study (68) of patients in acute stages of viral hepatitis showed increased half-life of valproic acid from 14. Effects of Liver Disease As primidone is metabolized to active compounds by the liver, little difference can be anticipated in a short course of therapy in liver disease. With long-term administration, changes similar to those seen with phenobarbital may be expected. No results from experimental investigation of primidone in liver disease are available. Clinical Recommendations Because primidone is metabolized to three active compounds, determination of plasma concentrations may help in assessing intoxications. Although it is unclear whether primidone may be removed by dialysis, its metabolite phenobarbital certainly will be. A case resembling Reye syndrome in a 7-year-old reported significantly increased formation of three monounsaturated and four double-unsaturated metabolites in plasma (58% to 71% of valproic acid compounds compared with a maximum of 15% in controls) and in urine (34% to 61% compared with a maximum of 10% in controls) (71). Serum-free carnitine, as well as the main oxidation metabolite 3-ketovalproic acid, decreased despite serum valproic acid concentration at the upper limit of the therapeutic range in a 3-year-old with valproic acid-induced Reye syndrome (72). Autopsy of a set of twins with a progressive hepatic encephalopathy revealed hepatic necrosis only in the sibling who had received valproic acid, indicating that the drug may have aggravated pre-existing hepatic pathology (73). This idiosyncratic reaction usually occurs during the first 6 months of treatment, and most cases have been reported in children. Other suggested associated risk factors for this condition include developmental delay and polytherapy. Histologic changes are variable, including cholestasis, centrilobular necrosis, and fatty changes. Clinical symptoms, such as nausea, vomiting, malaise, and breakthrough seizures, often appear before liver function tests become abnormal (75). Valproic acid causes metabolic changes because of the inhibition of enzymes involved in intermediary cell metabolism. Moderate elevations of blood ammonia are common in patients receiving valproic acid and usually do not require treatment in the absence of clinical symptoms (76). Effects of Renal Disease Hooper and associates (78) found no evidence of reduced protein binding in patients with renal disease. Because only 1% of carbamazepine is eliminated unchanged in urine, accumulation of parent drug or the epoxide metabolite is unlikely. No studies are available on the effects of dialysis on the drug or its metabolites. Effects of Liver Disease Significant reduction in the percentage of carbamazepine bound to protein occurred in patients with mild liver disease (78). No clear correlation between any laboratory parameter and the degree of impairment could be determined. Clinical Recommendations Dose adjustment is not needed in either renal disease or dialysis. However, close monitoring of serum levels of carbamazepine and the 10,11-epoxide should be maintained, especially with long-term administration in patients with liver dysfunction.

These efforts must be supported by an increase in the amount of attention given to communication, for example in the form of compelling advocacy to those policy makers capable of mobilizing resources. It is equally important to foster strategic alliances, reach agreement on priority target groups, and support behavioral change. The social marketing perspective is also critical for iron, particularly when new and affordable iron-containing products are introduced in a society or group. The main challenge in food fortification is to enable universal fortification of staple foods or condiments with meaningful levels of iron. This involves systematic planning and collaboration with the food processing industry in addressing issues of coverage, cost, effectiveness, benefits, and risk in relation to gains, performance of the technology within the environmental, socioeconomic and cultural context of the recipient population, the identification of intended beneficiaries, their needs, and their social and economic circumstances. Parallel with improving bioavailability of iron compounds (including encapsulated forms of iron), development of other strategies to effectively improve iron utilization from the diet also needs increased attention. In the area of iron supplementation, in addition to timely supply of good quality supplements and effective delivery systems, there is also the challenge of ensuring high compliance for the supplementation programs to be successful. Ensuring effectiveness through improved programming and assured provision of higher quality supplements to target groups and addressing factors that limit motivation to take supplements have the largest potential to improve program effectiveness. The potential of the food industry to create nutritious complementary foods for young children has hardly been tapped and has yet to be developed. A basic yet formidable challenge is putting iron on the agenda of policy makers and development agencies nationally and globally. Creating awareness, building alliances, and mobilizing actors at all levels and sectors is critical. While the starting point is to address key issues and propose consensus statements that provide clarity to policy makers and program planners in order to strengthen and expand programs, the information that a policy maker needs does not flow automatically from scientific consensus and technological feasibility. We need to build much better bridges between those that have the science and technology, those that deliver the the case for urgent action to address nutritional anemia 17 tionally adequate diet for infants (complementary to breast milk and home-prepared complementary foods)­especially to meet the micronutrient requirements of infants for iron and zinc. Beyond having a superior micronutrient content to that of home-prepared rice porridge and other traditional infant foods, industrially fortified complementary foods also have the advantages of delivering higher bioavailability of micronutrients, higher energy density, and higher protein quality, all in a safe and convenient manner. From the food technology perspective, the challenge is to increase both the energy density of complementary foods and levels of iron and other nutrients (and eliminate absorption-inhibiting factors) at an affordable price. From the public health perspective, we need a combination of proper regulation that protects infant health yet supports industrial innovation, and strong public education on appropriate practices of feeding and caring for infants and young children. Large and rapid growth in the production and consumption of fortified complementary foods will be possible only through an effective public-private social marketing partnership to increase the percentage of infants and young children who are fed fortified complementary foods and promote the use of fortified complementary foods only in the latter half of infancy and the second year of life. A combination of interventions need to be universally advocated and implemented including supplementation of at-risk groups, universal and targeted fortification, dietary modification, parasitic disease and malaria control, and vitamin A interventions, in addition to overall education of policy makers, professionals and the public. Programmatically, the priority in global efforts to increase the iron intakes of vulnerable populations almost certainly should be given to national scale programs for: · Fortification of staple foods, condiments, and complementary foods with bioavailable forms of iron (care is needed in selecting the compound and the level of fortification); · Iron supplementation programs for the highest priority population groups: pregnant women, children under two and adolescent girls. Country strategies must be tailored to suit specific national paradigms, combining complementary and effective interventions that will result in the most cost-effective model. In the wider picture there is certainly need to establish and scale up effective technologies (especially in using iron compounds that do not impart color or react with food matrices while offering a good bioavailability). Issues of demand, supply and logistics, communications and community participation, partnership building across a wide spectrum of players ­ public and private ­ are equally important to ensure the success and sustainability of efforts to eliminate anemia and iron deficiency in large populations.

The pial dissection along the olfactory nerve is then carried anteriorly to avoid disruption of the nerve. The remaining gyrus rectus is then aspirated with the posterior removal limited by the internal carotid artery. The deep white matter and mesial frontal gyri are removed in subpial fashion by a dissection plane marked by the anterior aspect of the frontal horn starting below the prior dissection of the genu of the corpus callosum. This dissection is carried out through the caudate nucleus along the course of the anterior cerebral artery to where it joins the internal carotid artery. Special care should be taken after the hemisphere is removed to ensure complete removal of the basal­posterior­frontal lobe. Once all the pial surfaces and white matter tracts have been cut, the draining veins to the sinuses are circumferentially coagulated and divided and any bleeding points packed with hemostatic agent. At this point the entire hemisphere can be removed in one anatomic piece and sent for pathologic study. The remaining amygdala­hippocampus bloc is then removed as the last portion of the procedure. The insular cortex can be removed if so desired by subpial aspiration using the ultrasonic aspirator or suction coagulation. As the middle cerebral artery has already been controlled, arterial injury is of less concern than in the functional hemispherectomy operation. Care must be taken to limit resection to the insular gyri to avoid injury to deeper thalamic/brainstem structures. Perhaps stereotactic imaging would be useful at this stage, although a practical approach is to stop the dissection when underlying white matter is reached. The classic anatomic hemispherectomy is supplemented by a muscle plug in the foramen of Monro on the resection side and by folding down the stripped dura of the convexity bone onto the falx, central block (composed by basal ganglia and thalamus and middle fossa cavity). Using this technique, there seems to be a higher rate of infection, but the rate of hydrocephalus seems to be reduced, compared to the classic anatomic resection (8). Functional Hemispherectomy and Other Disconnection Techniques Classic Functional Hemispherectomy this technique was first described in Montreal by Rasmussen and colleagues in an effort to prevent the late hemorrhagic complications described after anatomical hemispherectomy, mainly hemosiderosis (5­7,28). It is unclear if late hemosiderosis was caused by chronic insidious bleeding into the remaining ventricular cavity or by chronic hydrocephalus, since the description of such complication was 40 to 50 years ago, before computerized tomography. Chapter 84: Hemispherectomies, Hemispherotomies, and Other Hemispheric Disconnections 953 observed, even in patients with more than 20 years in followup. In the functional hemispherectomy procedure, the same T-shaped scalp incision is performed. The craniotomy is smaller than in the anatomical hemispherectomy, especially in the anterior­posterior orientation, and is mainly centered in the topographic location of the insula. The dura is open at the same matter as it has been described for the anatomical hemispherectomy. The overall goal of the functional hemispherectomy is to disconnect the frontal lobe from an incision that is placed just anterior to the genu of the corpus callosum and to disconnect the parietal and occipital lobe through a posterior incision, and then to remove the temporal lobe and its mesial structures. The fiber tracts projecting from the remaining parts of the frontal, parietal, and occipital lobes to the brainstem and spinal cord are then transected. The first cortical incision is made along the upper margin of the sylvian fissure, by coagulating and incising the pia and its blood vessels, dissecting down into the frontal and parietal operculum, down to the plane of the insular cortex. From the anterior and posterior ends of this dissection, a central resection is performed, exposing the entire limitans sulcus of the insula and, consequently, the insula cortex. The incisions are extended to the medial surface to the level of the cingulate gyrus, which is preserved at this stage to protect the pericallosal artery, but removed later. By deepening the dissections in the superior limitans sulcus of the insula, the body of the lateral ventricle is entered and the central bloc of tissue removed. The temporal lobe is removed by coagulating and dividing the pia and its vessels along the superior temporal gyrus, back to the posterior limb of the upper resection, and anteriorly around the temporal pole, down to the uncus. The roof of the temporal horn is entered and then the lateral portion of the temporal lobe is removed through the collateral sulcus. The hippocampus is dissected and removed through the coagulation of the hippocampus sulcus. The deep white matter of the medial and inferior aspects of the frontal lobe is divided in the coronal plane, from the central resection area to the most basal and posterior area of the frontal lobe, just rostral to the anterior perforated substance and medial and lateral olfactory striae.

Process of soliciting international input on proposed changes from gender identity professionals and the transgender community; 3. Smoller1,2,3 Abstract Genome-wide association studies have identified many variants that each affects multiple traits, particularly across autoimmune diseases, cancers and neuropsychiatric disorders, suggesting that pleiotropic effects on human complex traits may be widespread. However, systematic detection of such effects is challenging and requires new methodologies and frameworks for interpreting cross-phenotype results. In this Review, we discuss the evidence for pleiotropy in contemporary genetic mapping studies, new and established analytical approaches to identifying pleiotropic effects, sources of spurious cross-phenotype effects and study design considerations. We also outline the molecular and clinical implications of such findings and discuss future directions of research. For example, twin and family studies have long provided evidence for genetic correlations among diseases (such as major depressive disorder and generalized anxiety disorder 10, or rheumatoid arthritis and systemic lupus erythematosus 11), suggesting a role for pleiotropic genetic effects. In addition, the co-occurrence of multiple diseases in the same individual (for example, type 1 diabetes and autoimmune thyroid disease12) also point to shared genetic causes. In some cases, the same variants show association with multiple traits; in other cases, although the same overall region is implicated, distinct nearby markers show signals of association with different traits. Distinguishing the associations that represent genuinely shared effects of single variants from those that represent the effects of colocalizing but independent variants is crucial, as they imply different notions of pleiotropy and mechanistic models of shared function. In brief, biological pleiotropy refers to a genetic variant or gene that has a direct biological influence on more than one phenotypic trait. Mediated pleiotropy occurs when one phenotype is itself causally related to a second phenotype so that a variant associated with the first phenotype is indirectly associated with the second. Studies in which hundreds of thousands (or millions) of genetic markers are tested for association with a phenotypic trait; they are an unbiased approach to survey the entire genome for disease-associated regions using common variation. Complex traits Traits controlled by a combination of many genes and environmental factors. Spurious pleiotropy encompasses various sources of bias that cause a genetic variant falsely to appear to be associated with multiple phenotypes. Overall, we conclude that despite various conceptual and technical challenges, the identification and characterization of this widespread pleiotropy is crucial for a comprehensive biological understanding of complex traits and disease states. Heritability the proportion of phenotypic variance attributed to genetic differences among individuals in a population. Such observations have usually been incidental, and studies of different traits have independently led to discoveries of associations with the same marker or region. The first examples of cross-disease metaanalyses (using methods described later) have discovered even higher levels of overlap: Cotsapas et al. In each scenario, the observed genetic variant (S) is associated with phenotypes 1 Nature Reviews Genetics and 2 (P1 and P2). In some cases, the causal variant may be identified directly and the figures can be simplified accordingly. The various figures correspond to the unobserved underlying pleiotropic structure. Colocalizing Different genetic variants in high linkage disequilibrium located in the same gene that affect different phenotypes. Single-nucleotide polymorphisms Single-nucleotides in the genome that vary across individuals in the population. Copy number variants Regions of the genome in which the copy number is polymorphic (for example, deletions and duplications) across individuals. Finally, studies using aggregate measures of genetic variation (such as polygenic genetic risk scores) have been used to demonstrate genetic covariation between two or more disorders. However, the misclassification rate must be quite high94 to have a substantial impact on the genetic correlation. In the cases of schizophrenia and bipolar disorder, the misclassification rate would need to be larger than 20% to generate the genetic correlation (0. These sources of bias are relevant for both multivariate and univariate analytical approaches (see the main text) and can be avoided with careful study design.

Participants with asthma, however, had higher baseline inflammation than healthy participants (Holgate et al. Both groups of volunteers had enhanced production of total immunoglobulin E (IgE) in the nose (Diaz-Sanchez et al. Studies of allergic response in mice and rats (generally sensitized and challenged with ovalbumin as the allergen) have used different protocols for administering the allergen, different timing of the diesel exposure relative to the administration of the allergen, and different route of exposure. Findings of adjuvant effects in humans, however, need to be validated in studies with more relevant exposure conditions. Also, there is some evidence in animals that other particles, such as Kanto loam dust, fly ash, carbon black, and alum (Maejima et al. However, conclusions about the studies in animals are difficult to generalize to humans because different effects can be observed when different animal species or study protocols are used. Other changes included a dose-related increase in mucus-cell metaplasia and lung inflammation. The effects reported in offspring exposed in utero included delayed or disturbed differentiation of the testis, ovary, and thymus (Watanabe and Kurita 2001) and delayed gonadal maturation and lower weight gain in the group exposed in utero to 3 mg/m3 (Tsukue et al. No effects on the weight of the testis, epididymis, or adrenal glands were observed. Daily sperm production was also decreased, but no dose­ response relationship was observed for any of these effects.

The International League Against Epilepsy (2) describes reflex epilepsies as "epilepsies characterized by specific modes of seizure precipitation. Reflex seizures may be classified as occurring in generalized or in focal epilepsy syndromes (4). Reflex seizures may not differ in semiology from those encountered in other forms of epilepsy but understanding of the seizure trigger is important in the management of the patient and study of the mechanisms of epileptogenicity. Seizures triggered by factors such as alcohol withdrawal are not included among reflex seizures. Arguing that no reflex arc is involved in reflex epilepsy, others proposed terms such as sensory precipitation (6,7) or stimulus sensitive epilepsies (8). Wieser (9) noted that sensory precipitation epilepsy is a misnomer because some reflex seizures are not precipitated by sensory stimuli. Although some investigators restrict the term reflex epilepsy to cases in which a certain stimulus always induces seizures (10), it may include cases in which spontaneous seizures also occur or instances in which the epileptogenic stimulus does not invariably induce an attack (11), which often occurs in patients taking antiepileptic drugs. The term "epilepsy with reflex seizures," although more cumbersome, perhaps better reflects clinical reality and more accurately describes cases with reflex and spontaneous attacks. Apart from epileptic photosensitivity to flickering light, cases of reflex epilepsy are relatively rare and permit glimpses into the mechanisms of epileptogenesis and the organization of cognitive function. The epileptogenic trigger must occur often enough in everyday life so that the patient suspects its relation to the resulting seizures. If the trigger is ubiquitous, however, the seizures appear to occur by chance or with no obvious antecedent. This chapter reviews the neurophysiology of reflex epilepsy from the available human and animal studies. We also discuss clinical features of reflex seizures classified by the triggering stimulus. In the first, irritative cortical lesions are created and their activation by specific stimuli is studied.
