Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modication of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease. This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. Decisions about whether to initiate specic preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord ing to simple predictions of absolute cardiovascular risk. Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances. Prevention of recurrent heart attacks and strokes in low and middle income populations. This proportion is equal to that due to infectious diseases, nutritional deciencies, and maternal and perinatal conditions combined (1). It is important to recognize that a substantial pro portion of these deaths (46%) were of people under 70 years of age, in the more productive period of life; in addition, 79% of the disease burden attributed to cardiovascular disease is in this age group (2). Between 2006 and 2015, deaths due to noncommunicable diseases (half of which will be due to cardiovascular disease) are expected to increase by 17%, while deaths from infectious diseases, nutritional deciencies, and maternal and perinatal conditions combined are projected to decline by 3% (1). Almost half the disease burden in low and middle-income countries is already due to noncommunicable diseases (3). In doing so, it placed noncommunicable diseases on the global public health agenda. However, population wide public health approaches alone will not have an immediate tangible impact on cardiovascular morbidity and mortality, and will have only a modest absolute impact on the disease burden (3, 4). A combination of population-wide strategies and strategies targeted at high risk individuals is needed to reduce the cardiovascular disease burden. In this context, it is imperative to target the limited resources on those who are most likely to benet. The objective is to reduce the incidence of heart attacks, strokes, and renal failure associated with hypertension and diabetes, as well as the need for amputation of limbs because of ischaemia, by reducing the cardiovascular risk. The focus is prevention of disability and early deaths and improvement of quality of life. This document should be considered as a framework, which can be adapted to suit different political, economic, social, cultural and medical circumstances. Interpretation and implications of recommendations (13, 14) the recommendations included here provide guidance on appropriate care. As far as possible, these are based on clear evidence that allows a robust understanding of the benets, tolerabil ity, harms and costs of alternative patterns of care. Recommendations can be dened as being strong when it is certain that their application will do more good than harm or that the net benets are worth the costs. Strong recommendations apply to most patients in most circumstances, and can be adopted as policy in most situations. Introduction 3 Recommendations can be dened as weak when it is uncertain that their application will do more good than harm or that the net benets are worth the costs. In this guide, such recommendations include the words suggest or should probably. Policy making related to weak recommendations requires substantial debate and the involvement of a range of stakeholders. Development of the guidelines this guide was developed on the basis of the total risk approach to prevention of cardiovascu lar disease, elaborated in the World Health Report 2002 (2). Development of the risk prediction charts started in 2003, followed by preparations for the development of this guide in 2004, using an evidence-based methodology. Tables were compiled, summarizing the available scientic evidence to address key issues related to primary prevention. A revised draft was then sent for peer review (see Annex 7 for a list of reviewers). The rate of progression of atherosclerosis is inuenced by cardiovascular risk factors: tobacco use, an unhealthy diet and physical inactivity (which together result in obesity), elevated blood pres sure (hypertension), abnormal blood lipids (dyslipidaemia) and elevated blood glucose (diabetes). Continuing exposure to these risk factors leads to further progression of atherosclerosis, resulting in unstable atherosclerotic plaques, narrowing of blood vessels and obstruction of blood ow to vital organs, such as the heart and the brain. The clinical manifestations of these diseases include angina, myocardial infarction, transient cerebral ischaemic attacks and strokes. Given this con tinuum of risk exposure and disease, the division of prevention of cardiovascular disease into primary, secondary and tertiary prevention is arbitrary, but may be useful for development of services by different parts of the health care system. The concept of a specic threshold for hyper tension and hyperlipidaemia is also based on an arbitrary dichotomy. The total risk of developing cardiovascular disease is determined by the combined effect of cardio vascular risk factors, which commonly coexist and act multiplicatively. Many people are unaware of their risk status; opportunistic and other forms of screening by health care providers are therefore a potentially useful means of detecting risk factors, such as raised blood pressure, abnormal blood lipids and blood glucose (18). The predicted risk of an individual can be a useful guide for making clinical decisions on the intensity of preventive interventions: when dietary advice should be strict and specic, when sug gestions for physical activity should be intensied and individualized, and when and which drugs should be prescribed to control risk factors. Such a risk stratication approach is particularly suitable to settings with limited resources, where saving the greatest number of lives at lowest cost becomes imperative (19). In patients with a systolic blood pressure above 150 mmHg, or a diastolic pressure above 90 mmHg, or a blood cholesterol level over 5. Therefore, targeting patients with a high risk is the rst priority in a risk stratication approach. Thus the use of guidelines based on risk stratication might be expected to free up resources for other compet ing priorities, especially in developing countries. It should be noted that patients who already have symptoms of atherosclerosis, such as angina or intermittent claudication, or who have had a myocardial infarction, transient ischaemic attack, or stroke are at very high risk of coronary, cerebral and peripheral vascular events and death. Risk stratication charts are unnecessary to arrive at treatment decisions for these categories of patients. Thus, it seems reasonable to assume that the evidence related to lowering risk factors is also applicable to people in different settings. Complementary strategies for prevention and control of cardiovascular disease In all populations it is essential that the high-risk approach elaborated in this document is comple mented by population-wide public health strategies 1) (11). Although cardiovascular events are less likely to occur in people with low levels of risk, no level of risk can be considered safe (32). Population-wide strategies will also support lifestyle modication in those at high risk. The extent to which one strategy is emphasized over the other depends on achievable effectiveness, cost-effectiveness and resource considerations. If resources allow, the target population can be expanded to include those with moderate levels of risk; however, lower ing the threshold for treatment will increase not only the benets but also the costs and potential harm. People with low levels of risk will benet from population-based public health strategies and, if resources allow, professional assistance to make behavioural changes. Ministries of health have the difficult task of setting a risk threshold for treatment that balances the health care resources in the public sector, the wishes of clinicians, and the expectations of the public. For example, in England, a 30% risk of developing coronary heart disease over a 10-year period was dened as high risk by the National Service Framework for coronary heart disease (34). This threshold would apply to about 3% of men in the population aged between 45 and 75 years. When the cardiovascular risk threshold was lowered to 20% (equivalent to a coronary heart disease risk of 15%), a further 16% of men were considered high risk and therefore eligible for drug treatments. Ministries of health or health insurance organizations may wish to set the cut-off points to match resources, as shown below for illustrative purposes. In a state-funded health system, the government and its health advisers are often faced with making decisions about the threshold at which drug and other interventions are affordable. In many health care systems, such decisions must be made by individual patients and their medical practitioners, on the basis of a careful appraisal of the potential benets, hazards and costs involved. Countries that use a risk stratication approach have tended to reduce the threshold of risk used to determine treatment decisions as the costs of drugs, particularly statins, have fallen and as adequate coverage of the population at the higher risk level has been achieved. In low-income countries, lowering the threshold below 40% may not be feasible because of resource limitations. Nevertheless, use of risk stratication approaches will ensure that treatment decisions are transparent and logical, rather than determined by arbitrary factors or promotional activity of pharmaceutical companies. Risk prediction charts: Strengths and limitations Use of risk prediction charts to estimate total cardiovascular risk is a major advance on the older practice of identifying and treating individual risk factors, such as raised blood pressure (hypertension) and raised blood cholesterol (hypercholesterolemia). Since there is a continuous relationship between these risk factors and cardiovascular risk the concept of hypertension and hyperlipidemia introduces an arbitrary dichotomy. The total risk approach acknowledges that many cardiovascular risk factors tend to appear in clus ters; combining risk factors to predict total cardiovascular risk is consequently a logical approach to deciding who should receive treatment. The risk charts and tables produced use different age categories, duration of risk assessment and risk factor proles. The current New Zealand (43) and Joint British Societies charts (40, 41) are similar in concept. Risk scores have different accuracy in different populations, tending to overpredict in low-risk populations and underpredict in high-risk populations. The threshold for high risk is dened as a risk of death of 5% or greater, instead of the composite fatal and non-fatal coronary endpoint of 20%. The evidence that underpins the use of risk factor scoring and management comes from a range of sources. There is now increasing evidence that cardiovascular risk factors are associated with clinical 10 Prevention of cardiovascular disease events in a similar way in a wide range of countries (31). Finally, there is strong evidence from clinical trials that reducing the levels of risk factors has benecial effects. Risk factor scoring and management have now been widely taken up in cardiovascular prevention guidelines in most high-income countries (36, 41, 43, 44). The risk factors included in current scoring systems are drawn from those used in the original Framingham score. It is possible that, as more epidemiologi cal data become available for low and middle-income countries, a new generation of risk scoring systems may emerge that have greater predictive accuracy. Older age and male sex are powerful determinants of risk; consequently, it has been argued that the use of the risk stratication approach will favour treatment of elderly people and men, at the expense of younger people with several risk factors and women. However, while younger people gain more life years if they have a non-fatal event, older people are a lot more likely to die from an event. When discounting is taken into consideration, the quality adjusted life years gained by preventing events in young people are very similar to those gained in old people (Table 3) (50). Concern about the metabolic syndrome, characterized by central obesity, elevated blood pressure, dyslipidaemia, and insulin resistance (51, 52), has raised the question of whether identifying people with this syndrome should be a priority. There is, as yet, insufficient evidence to justify using metabolic syndrome as an additional risk prediction tool (63, 64). There is insufficient evidence from randomized trials to support more specic management of dyslipidaemias (81). In summary, the great strength of the risk scoring approach is that it provides a rational means of making decisions about intervening in a targeted way, thereby making best use of resources available to reduce cardiovascular risk. Alternative approaches focused on single risk factors, or concepts such as pre-hypertension or pre-diabetes, have been popular in the past, often because they represented the interests of specic groups in the medical profession and professional societ ies. Such an approach, however, leads to a very large segment of the population being labelled as high risk, most of them incorrectly.

Children with minor illnesses menstruation girls buy generic cabergoline on-line, such as upper respiratory tract infec tion womens health editor purchase cabergoline now, may be immunized (see Vaccine Safety women's health clinic john flynn order generic cabergoline pills, p 41). However, if other manifestations suggest a more serious illness, the child should not be immunized until recovery has occurred. Immunocompromised patients with disorders associated with increased severity of viral infections should not receive live-virus rubella vaccine (see Immunocompromised Children, p 74). If possible, children receiving biologic response modifers, such as anti tumor necrosis factor-alpha (see Biologic Response Modifers, p 82), should be immu nized prior to initiating treatment. The risk of rubella expo sure for patients with altered immunity can be decreased by immunizing their close susceptible contacts. Although small amounts of virus are shed after immunization, no evidence of transmission of vaccine virus from immunized children has been found. For patients who have received high doses of corticosteroids (2 mg/kg or greater or more than 20 mg/day) for 14 days or more and who otherwise are not immunocompromised, the recommended interval before immunization is at least 1 month (see Immunocompromised Children, p 74) after steroids have been discontinued. The most common illness associated with nontyphoidal Salmonella infection is gastroenteritis, in which diarrhea, abdominal cramps, and fever are common manifestations. Sustained or intermittent bacteremia can occur, and focal infections are recognized in as many as 10% of patients with nontyphoidal Salmonella bacteremia. Salmonella enterica serotypes Typhi, Paratyphi A, Paratyphi B, and certain other uncommon serotypes can cause a protracted bacteremic illness referred to , respectively, as typhoid and paratyphoid fever and collectively as enteric fevers. The onset of enteric fever typically is gradual, with manifestations such as fever, constitutional symptoms (eg, headache, malaise, anorexia, and lethargy), abdominal pain and tenderness, hepato megaly, splenomegaly, dactylitis, rose spots, and change in mental status. In infants and toddlers, invasive infection with enteric fever serotypes can manifest as a mild, nondescript febrile illness accompanied by self-limited bacteremia, or invasive infection can occur in association with more severe clinical symptoms and signs, sustained bacteremia, and meningitis. More than 2500 Salmonella serotypes have been described; most sero types causing human disease are classifed within O serogroups A through E. Salmonella serotype Typhi is classifed in O serogroup D, along with many other common serotypes including serotype Enteritidis. In 2009, the most commonly reported human isolates in the United States were Salmonella serotypes Enteritidis, Typhimurium, Newport, Javiana, and Heidelberg; these 5 serotypes generally account for nearly half of all Salmonella infections in the United States ( The major food vehicles of transmission to humans include food of animal origin, such as poultry, beef, eggs, and dairy products. Other food vehicles (eg, fruits, vegetables, peanut butter, frozen pot pies, powdered infant formula, cereal, and bakery products) have been implicated in outbreaks, presumably when the food was contaminated by contact with an infected animal product or a human carrier. Other modes of transmission include ingestion of contaminated water; contact with infected reptiles or amphibians (eg, pet turtles, iguanas, lizards, snakes, frogs, toads, newts, salamanders) and rodents or other mammals. Unlike nontyphoidal Salmonella serotypes, the enteric fever serotypes (Salmonella serotypes Typhi, Paratyphi A, Paratyphi B) are restricted to human hosts, in whom they cause clinical and subclinical infections. Chronic human carriers (mostly involving chronic infection of the gall bladder but occasionally involving infection of the urinary tract) constitute the reservoir in areas with endemic infection. Infection with enteric fever serovars implies ingestion of a food or water vehicle contaminated by a chronic carrier or person with acute infection.

In the current taxonomy, only 2 species are recognized, Salmonella enterica and Salmonella bongori. S enterica has 6 subspecies, of which subspecies I (enterica) contains the overwhelming majority of all Salmonella pathogens that affect humans, other mam mals, and birds. Serotypes are now written nonitalicized with a capital frst letter (eg, Typhi, Typhimurium, Enteritidis). The serotype of Salmonella is determined by its O (somatic) and H (fagellar) antigens and whether Vi is expressed. Consequently, typhoid fever and paratyphoid fever infections in residents of the United States usually are acquired during international travel. Age-specifc incidences for nontyphoidal Salmonella infection are highest in children younger than 4 years of age. Most reported cases are sporadic, but widespread outbreaks, includ ing health care-associated and institutional outbreaks, have been reported. The incidence of nontyphoidal Salmonella gastroenteritis has diminished little in recent years, in contrast to other enteric infections of bacterial etiologies. Every year, nontyphoidal Salmonella organisms are one of the most common causes of laboratory-confrmed cases of enteric disease reported by the Foodborne Diseases Active Surveillance Network (FoodNet [ A potential risk of transmission of infection to others persists for as long as an infected person excretes nontyphoidal Salmonella organisms. Twelve weeks after infection with the most common nontyphoidal Salmonella serotypes, approximately 45% of children younger than 5 years of age excrete organisms, compared with 5% of older children and adults; antimicrobial therapy can prolong excretion. Approximately 1% of adults con tinue to excrete Salmonella organisms for more than 1 year. Diagnostic tests to detect Salmonella antigens by enzyme immunoassay, latex agglutination, and monoclonal anti bodies have been developed, as have assays that detect antibodies to antigens of enteric fever serotypes. Gene-based polymerase chain reaction diagnostic tests also are available in research laboratories. The sensitivity of blood culture and bone marrow culture in children with enteric fever is approximately 60% and 90%, respectively. The combination of a single blood culture plus culture of bile (collected from a bile-stained duodenal string) is 90% in detecting Salmonella serotype Typhi infection in children with clinical enteric fever. Resistance to these antimicrobial agents is becoming more common, especially in resource-limited countries. In areas where ampicillin and trimethoprim-sulfamethoxazole resistance is common, a fuoroquinolone or azithromycin usually is effective. However, fuoroquino lones are not approved for this indication in people younger than 18 years of age (see Fluoroquinolones, p 800). Once antimicrobial susceptibility test results are available, ampicillin or ceftriaxone for susceptible strains is recommended for at least 4 to 6 weeks. Drugs of choice, route of administration, and duration of therapy are based on susceptibility of the organism (if known), knowledge of the anti microbial susceptibility patterns of prevalent strains, site of infection, host, and clinical response. Multidrug-resistant isolates of Salmonella serotypes Typhi and Paratyphi A and strains with decreased susceptibility to fuoroquinolones are common in Asia and are found increasingly in travelers to areas with endemic infection. Invasive salmonel losis attributable to strains with decreased fuoroquinolone susceptibility is associated with greater risk for treatment failure. Salmonella serotypes Typhi and Paratyphi A and nontyphoidal Salmonella isolates with ciprofoxacin resistance or that produce extended spectrum beta-lactamases occasionally are reported. Empiric treatment of enteric fever with ceftriaxone or fuoroquinolone is recommended, but once antimicrobial sus ceptibility results are known, therapy should be changed as necessary. Azithromycin is an effective alternative for people with uncomplicated infections. Aminoglycosides are not recommended for treatment of invasive Salmonella infections. The chronic carrier state may be eradicated by 4 weeks of oral therapy with ciprofoxacin or norfoxacin, antimicrobial agents that are highly concen trated in bile. High-dose parenteral ampicillin also can be used if 4 weeks of oral fuo roquinolone therapy is not well tolerated (see Fluoroquinolones, p 800). Cholecystectomy may be indicated in some adults if antimicrobial therapy alone fails. These drugs should be reserved for critically ill patients in whom relief of manifestations of toxemia may be life saving. The usual regimen is high-dose dexamethasone given intravenously at an initial dose of 3 mg/kg, followed by 1 mg/kg, every 6 hours, for a total course of 48 hours. In children with typhoid fever, precautions should be continued until culture results for 3 consecutive stool specimens obtained at least 48 hours after cessation of antimicro bial therapy are negative. Notifcation of public health authorities and determination of serotype are of primary importance in detection and investigation of outbreaks. Specifc strategies for controlling infection in out-of-home child care include adherence to hygiene practices, including meticulous hand hygiene and limiting exposure to reptiles and rodents (see Children in Out-of-Home Child Care, p 133). When nontyphoidal Salmonella serotypes are identifed in a symptomatic child care attendee or staff member with enterocolitis, older children and staff members do not need to be excluded unless they are symptomatic. Stool cultures are not required for asymptomatic contacts or for return to child care following resolution of illness. Antimicrobial therapy is not recommended for people with asymptomatic nontyphoi dal Salmonella infection or uncomplicated diarrhea or for people who are contacts of an infected person. When Salmonella serotype Typhi infection is identifed in a child care staff member, local or state health departments may be consulted regarding regulations for length of exclusion and testing, which may vary by jurisdiction. Resistance to infection with Salmonella serotype Typhi is enhanced by typhoid immunization, but currently licensed vaccines do not provide complete protec tion. Vaccine is selected on the basis of age of the child, need for booster doses, and possible contraindications (see Precautions and Contraindications, p 640) and reactions (see Adverse Events, p 640). Risk is greatest for travelers to the Indian subcontinent, Latin America, Asia, the Middle East, and Africa who may have prolonged exposure to contaminated food and drink. Such travelers need to be cautioned that typhoid vaccine is not a substitute for careful selection of food and drink (see Children (6 years of age and older) and adults should take 1 enteric-coated capsule every other day for a total of 4 capsules. The capsules should be kept refrigerated, and all 4 doses must be taken to achieve maximal effcacy. Commercially Available Typhoid Vaccines in the United States Minimum Age of Booster Adverse Typhoid Receipt, No. Results of 2 feld trials suggest that Ty21a may provide partial cross-protection against Salmonella serotype Paratyphi B. In circumstances of continued or repeated exposure to Salmonella serotype Typhi, periodic reimmunization is recommended to maintain immunity. Continued effcacy for 7 years after immunization with the oral Ty21a vaccine has been demonstrated; however, the manufacturer of oral Ty21a vaccine recommends reimmunization (completing the entire 4-dose series) every 5 years if continued or renewed exposure to Salmonella serotype Typhi is expected. No data have been reported concerning use of one vaccine administered after primary immunization with the other. The oral Ty21a vaccine produces mild adverse reactions that may include abdominal discomfort, nausea, vomiting, fever, headache, and rash or urticaria. No data are available regarding effcacy of typhoid vaccines in children younger than 2 years of age. The oral Ty21a vaccine requires replication in the gut for effectiveness; it should not be administered during gastrointestinal tract illness. Studies have demonstrated that simultaneous administration of either mefoquine or chlo roquine with oral Ty21a results in an adequate immune response to the vaccine strain. However, if mefoquine is administered, immunization with Ty21a should be delayed for 24 hours. Also, the antimalarial agent proguanil should not be administered simultane ously with oral Ty21a vaccine but, rather, should be administered 10 or more days after the fourth dose of oral Ty21a vaccine. Antimicrobial agents should be avoided for 24 or more hours before the frst dose of oral Ty21a vaccine and 7 days after the fourth dose of Ty21a vaccine. In older children and adults, the sites of predilection are interdigital folds, fexor aspects of wrists, extensor surfaces of elbows, anterior axillary folds, waistline, thighs, navel, genitalia, areolae, abdo men, intergluteal cleft, and buttocks. In children younger than 2 years of age, the erup tion generally is vesicular and often occurs in areas usually spared in older children and adults, such as the scalp, face, neck, palms, and soles. The eruption is caused by a hyper sensitivity reaction to the proteins of the parasite. Characteristic scabietic burrows appear as gray or white, tortuous, thread-like lines. Excoriations are common, and most burrows are obliterated by scratching before a patient is seen by a physician. Occasionally, 2 to 5-mm red-brown nodules are present, particularly on covered parts of the body, such as the genitalia, groin, and axilla. These scabies nodules are a granulomatous response to dead mite antigens and feces; the nod ules can persist for weeks and even months after effective treatment. Studies have demonstrated a cor relation between poststreptococcal glomerulonephritis and scabies. Crusted (Norwegian) scabies is an uncommon clinical syndrome characterized by a large number of mites and widespread, crusted, hyperkeratotic lesions. Crusted scabies usually occurs in debilitated, developmentally disabled, or immunologically compromised people but has occurred in otherwise healthy children after long-term use of topical corticosteroid therapy. Larvae emerge from the eggs in 2 to 4 days and molt to nymphs and then to adults, which mate and produce new eggs. S scabiei subspe cies canis, acquired from dogs (with clinical mange), can cause a self-limited and mild infestation usually involving the area in direct contact with the infested animal that will, in humans, resolve without specifc treatment. Because of the large number of mites in exfoliating scales, even minimal contact with a patient with crusted scabies may result in transmission.

Comparison and correlation of surface lobe seizures with scalp/sphenoidal recordings pregnancy halloween shirts quality 0.5mg cabergoline. Hughlings Jackson was the first to theorize that focal seizures are caused by a sudden and excessive discharge of gray matter in some part of the brain and that the clinical manifestations of the seizure depend on the seat of the discharging lesion (2 generations women's health center boca raton order cabergoline 0.5mg mastercard,3) women's health clinic denton tx buy cabergoline line. During the second half of the 19th century breast cancer volleyball shirts discount cabergoline 0.5 mg with amex, Fritsch and Hitzig pioneered stimulation of the brain in animals (4) menstrual vs pregnancy cramps purchase cabergoline visa. They discovered that electrical stimulation of the exposed cerebral cortex produced contralateral motor responses in dogs (5 breast cancer vs testicular cancer buy cabergoline no prescription,6). Experimental faradic stimulation of the human cerebral cor tex was first performed by Bartholow in 1874 (7). In 1909, Cushing reported that faradic stimulation of the postcentral gyrus could be used to determine the anatomic relationship of the sensory strip to an adjacent tumor (8). Motor responses elicited by electrical stimulation in humans were first described by Krause in the beginning of the 20th century (9), and by Foerster more than 70 years ago (2). The stippled area illustrates the supplementary sensorimotor cortex on the mesial aspect. The term prefrontal extent of interconnected neural networks underlying motor cortex is used to define the extensive part of the frontal lobe control (14). This concept has influenced our understanding of the various motor manifestations of seizures (17). Each level of motor control retains a somatotopic organization and receives peripheral sensory information that is used to modify the motor output at that level (18). The cerebral cortex exerts its motor control by way of the corticospinal and corticobulbar pathways. About three-fourths of the corticospinal fibers cross the mid Brainstem Motor Efferents line in the pyramidal decussation at the junction of the the brainstem gives rise to several descending motor path medulla and spinal cord and descend in the spinal cord as the ways, which are divided into ventromedial and dorsolateral lateral corticospinal tract (19). The lateral and ventral divi the ventral columns of the spinal cord and terminates predom sions of the corticospinal tract terminate in approximately inantly in the medial part of the ventral horn, which contains the same regions of spinal gray matter along with corre the motor nuclei controlling proximal limb and axial muscle sponding brainstem-originating pathways. In contrast, the dorsolateral system descends in the corticospinal tract terminals project on spinal interneurons. Thus, the dorsolateral motor system places its these anatomic arrangements of descending tracts underlie emphasis on muscles devoted to fine motor control. Motor Cortex Efferents the axons that project from layer V of the cortex to the Motor Cortex Afferents spinal cord run together in the corticospinal tract (a massive the major cortical inputs to the motor areas of cortex are bundle of fibers containing approximately 1 million axons). Other corticocortical internal capsule to reach the ventral portion of the brainstem inputs arrive from the opposite hemisphere through the cor and send collaterals to the striatum, thalamus, red nucleus, pus callosum. Many of these relationships well as homologous areas of the two hemispheres (28,29). In the brainstem, the corti from the thalamus, where separate nuclei convey modulating cobulbar fibers terminate bilaterally in cranial nerve motor inputs from the basal ganglia and the cerebellum (27). These areas are considered a part of the cortical inhibitory motor system, the epileptic activation of which may give rise to focal inhibitory motor seizures (also referred to by some authors as akinetic seizures). One seed region is placed in one motor area and the target region is placed in the effects of functional localization and effects of electri the contralateral motor area. Computed tracts course across the cor cal stimulation in the three broad motor areas are briefly dis pus callosum as expected. The tracts are displayed as a red 3D overlay cussed below: on black and white anatomic cut-planes. On the basis the motor cortex and other eloquent brain cortical areas are of cytoarchitectonic criteria, area 4 is recognized primarily by afforded by direct cortical stimulation. The cen mental model that can be used to reproduce the effects of cor tral sulcus marks the border between the agranular motor cor tical activation after an ictal discharge (30). The latter becomes apparent only if the patient engages in spe There are several characteristic features identifying the cen cific tasks during stimulation. In areas such as the supplemen tral sulcus, three of which are shown in the cartoon of Fig tary motor cortex, both positive responses in the form of bilat ure 13. The patient matory feature of the hand knob on the sagittal plane is unaware of the effects of stimulation unless asked to per is that it appears as if forming a backwards hook (see form the specific function integrated by the stimulated cortical. To distinguish the two negative motor areas, investiga aided by demarcation of the pre and postcentral sulci. Shown as overlaid white line segments are the omega of the hand knob (left image) and the pars marginalis smile (middle image). The middle image also demonstrates the architecture of the superior frontal gyrus termi nating posteriorly in the precentral gyrus. When local anesthesia right pars marginalis assume the characteristic appearance that is used, motor responses are usually evoked with currents of resembles a smile or bracket, which can be seen on multiple axial sections, making identification easy. Electrical cortical stimulation studies uncover the individual variability in the topographic organization of sensori motor maps in humans with structurally normal anatomy (48). The importance of direct cortical stimulation studies in patients the left and right ascending rami appear on axial images as with lesions and/or epileptogenic foci encroaching on the senso bilaterally paired paramedian features that together form the rimotor cortex cannot be overemphasized (49). This characteristic appearance is often preserved over multiple axial slices and can be used to identify the central sulcus, and differentiate it Supplementary Sensorimotor Area from the adjacent postcentral sulcus. In contrast to area 4, area 6 does not contain altered during motor learning or after injury (43). Muscle groups involved in fine movements feature a disproportionately large representation. Images are provided in coronal oblique reformatted planes that are roughly parallel to the motor strip. The toe, knee, shoulder, and finger tasks employed flexion/extension or tapping at a rate of about 2 per second, using the right-sided limb only. The eye blink, lip (pursing), and tongue (pressing against palate) tasks were bilateral motions performed at a similar rate. Right lower extremity movements are clearly localized along the left superior-medial cortical surfaces, with right upper extremity movements localized along left superior-lateral cortical surfaces. Note bilateral motions from eyes, lips, and tongue show corresponding bilateral activation. Recent quantitative architectonic and neurotransmitter With the advent of subdural electrodes, the Cleveland Clinic studies have corroborated the presence of similar topographic series of extraoperative stimulation studies showed that positive boundaries in the human brain (37,65). The rostral subdivision motor responses were not restricted to the mesial aspect of the covers the anterior part of the precentral gyrus, and its caudal superior frontal gyrus, but could also be elicited from its dorsal counterpart resides in the posterior part of the superior and mid convexity, the lower half of the paracentral lobule, and the pre dle frontal gyri, in front of the precentral sulcus (70). The the lower extremities represented posteriorly, head and face most divergence is largely caused by the methodological differences of anteriorly, and the upper extremities between these two regions neuroimaging and electrical cortical stimulation studies. This section reviews the elementary motor phenomena result ing from a variety of focal motor seizures. The terms patients with epilepsy who were between the age of 16 and 66 localization-related or partial seizures have been used to years, 18% had simple partial seizures (79). It may, therefore, be seizures, sensory phenomena were observed in approximately difficult to ascertain the level of consciousness in several one-third of patients exhibiting focal motor seizures (81). In the past, the presence or Postictally, patients may experience a transient functional absence of altered awareness was used to dichotomize seizures deficit, such as localized paresis (Todd paralysis), which may of focal onset into simple partial and complex partial. This is now proposed to move away from this dichotomy, which interesting clinical phenomenon of postepileptic paresis is seems to have lost its meaningful precision (76). Bentley Todd, who first described it in the mid-19th Seizures (75) divides focal motor seizures into those with or century (82). Todd paralysis is believed to result from persis without a march, versive, postural, and phonatory seizures. The diagnostic scheme proposed in 2001 is based on the use of Postictal Todd paralysis is a clinical sign of substantial value in a system of five axes (levels) intended to provide a standardized lateralizing the hemisphere of seizure onset (83). Axis 2 now defines the epileptic seizure type or types experienced by the patient. These movements recur at regular with focal negative myoclonus, and, finally, with inhibitory intervals of less than 1 to 2 seconds. The addition of axis 1 allows for the systematic brief and last for less than 1 or 2 minutes. During this period, description of ictal semiology observed during seizures utilizing clonic movements may remain restricted to one region or a standardized glossary of descriptive terminology (77). The majority of focal motor motor phenomena may be subdivided into elementary motor seizures tend to involve the hand and face, although any body manifestations (such as tonic, clonic, dystonic, versive) and part may potentially be affected (85). Automatisms consist of a more or less co attributed to the large cortical representation of the hand and ordinated, repetitive motor activity (such as oroalimentary, face area. The typical manifestation of a localized discharge manual or pedal, vocal or verbal, hyperkinetic or hypokinetic) within the precentral gyrus is clonic twitching of specific con (77). Somatotopic modifiers may be added to describe the tralateral muscle groups, as determined by their proportionate body part producing motor activity during seizures. Another recent seizure classification is based on the clinical the clonic movements are usually limited to the corre symptomatology and is independent of electroencephalo sponding area of the body, but may spread during the attack. The term Jacksonian seizures was proposed by Charcot in 1887 to Many types of myoclonic phenomena. Typically, myoclonic jerks are arrhythmic observations, which provided the basis for his revolutionary compared with clonic motor activity. But from the focus discharging primar ily the discharge spreads laterally to the adjacent healthy foci. Video recordings can be helpful, but cannot replace spreads toward a more proximal part. The term myoclonic seizure is described three variants: (i) fits starting in the hand (most reserved for epileptic seizures, whose main components are often in the thumb or both), (ii) fits starting in one side of single or repeated epileptic myoclonias (92). Gastaut distin the face (most often near the mouth), and (iii) fits starting guished epileptic myoclonic events into generalized, segmen in the foot (nearly always in the great toe) (3). Typically, tal, and focal, according to whether the seizures affected the consciousness remains intact and secondary generalization of entire body, one or more limbs, ipsilateral body parts/ Jacksonian seizures is uncommon. At times, the march may segments, or only one part of a single limb, respectively (93). Others view focal cortical children and found that the majority (25 out of 60) began in myoclonus as one manifestation of focal motor seizures, given the face (eight in the periocular and five in the perioral that myoclonus in this instance results from a hypersynchro region), 17 in the hand, seven in the arm, two in the shoulder, nous discharge arising from a distinct population of cortical and nine in the leg and foot (88). Focal corti Lastly, the term hemiconvulsions refers to unilateral clonic cal myoclonus has been described in patients with focal seizures. In a report of hemiparesis are described in the childhood syndrome of four children with perirolandic cortical dysplasia presenting hemiconvulsion-hemiplegia-epilepsy. In the last 3 years, she has been experiencing daily very brief seizures involving the muscles of the lower face on the right side without alteration of awareness. A: Clinical onset in the middle of this 10-second page punctuated by tonic contraction of the right facial musculature with involun tary right eye closure and deviation of the jaw towards the right, associated with voluntary reactive tensing of the entire face, as evidenced by the wide spread and asymmetric tonic muscle A artifact. Because of its very high voltage, the artifact appears widespread on this printed page. Note that in this instance, the terminal muscle jerk is indeed associated with myogenic artifact primarily involving the right-sided derivations. It becomes evident that different Finally, the paradoxical term negative myoclonus is types of tonic seizures utilize different neuroanatomical reserved for cases of sudden, brief relaxations in tonic muscle pathways, which is hardly surprising given that tonic contraction (89). Negative myoclonus (which also encom seizures may be a common clinical manifestation resulting passes the phenomenon of asterixis typically seen in toxic from a variety of different pathophysiologies underlying metabolic encephalopathies) is a nonspecific manifestation symptomatic and less frequently idiopathic epilepsies. Nonepileptic focal tonic symptoms can result from sub Epileptic negative myoclonus can be either unilateral or cortical pathology. In addition, erogeneous epilepsies ranging from the benign idiopathic paroxysmal tonic phenomena may be seen as part of certain epilepsies to severe epileptic encephalopathies (96). Tonic Seizures Tonic seizures consist of sustained muscle contractions that Oculocephalic Deviation usually last for more than 5 to 10 seconds and result in pos and Versive Seizures turing of the limbs or whole body (97). From the standpoint of clinical semiology, tonic seizures can be described according Foerster and Penfield first described versive seizures in 1930. Generalized tonic seizures involve axial and limb contraction of head and eye muscles (105). Unequal or sciousness is often lost by the time a patient experiences ver asynchronous contraction of muscle groups involving both sion, occasionally patients may be aware of the forced, invol sides of the body results in bilateral asymmetric tonic seizures. Contraction restricted to a portion of the body on one side As discussed, cortical stimulation studies have confirmed only gives rise to focal tonic seizures (98). Stimulation of more posterior points focal tonic seizures are attributed to activation of Brodmann (closer to the central sulcus) elicited contralateral, ipsilateral, area 6 (and the mesial frontal region in particular), some over or upward eye movements. Head rotation was usually seen in lap in symptomatology occurs, with ictal involvement of the conjunction with contralateral eye rotation.
