Even when you go through the right door antibiotic names medicine generic bactrim 960mg fast delivery, you may have bad luck because some of your energy may have gone in the left door virus alert 960mg bactrim sale. Thus antimicrobial disinfectant buy bactrim in united states online, you need to touch eight things using your right hand to prevent bad things from happening antibiotics for acne in south africa order bactrim 960mg free shipping. Managing discomfort differently At the beginning of this chapter antibiotics for uti uti order bactrim amex, we talk about the way most people automati cally respond when they hear a sneeze infection from bug bite purchase bactrim master card. People struggle for years and suffer significant discomfort when attempting to quit smoking, partly because smoking is a habit and partly because nicotine is highly addictive, which compounds the problem. But persistence and willingness to tolerate discomfort will eventually break them down. Consider reading Chapter 9 on mindfulness for ideas about how to tolerate discomfort. However, most people will experience greater success if they work in collaboration with a mental-health professional trained in this approach. For example, wishing someone good luck is not necessarily a bad thing and it conveys a positive sentiment. You can either make multiple copies of the page and slowly destroy each one, or you can continue to cross the words out, over and over. Try to stay with the exercise until your feelings come down by 50 percent or more. For exam ple, some people with hit-and-run issues who fear running someone over with their car may count compulsively while driving in order to shut out their obsessive images. Each of these four types of behaviors can be treated using a two-step approach that involves changing how the behaviors are done and then not doing them! Those who have this problem count all kinds of things, such as: Books on a bookshelf Cars passing Change and money Letters in words, names, sentences, or paragraphs Highway markings and signs Lines in the sidewalk Streetlights Some people count consecutively; others like to count in sets of specific numbers, such as groups of four or seven. Or a woman may look out the window and feel compelled to count cars in sets of five until she has logged six sets. When counting gets out of control, however, the person cannot focus on work or other important life tasks. Jot down notes about what it is you actually find yourself counting and when you usually do it. Thus, you could skip counting a few steps, count one step as three, or count totally out of order. If you attempt this technique, be sure to Miscount for ever increasingly large blocks of time. Expect some discomfort and rate that discomfort (see Ugh Factor Rating in Chapter 10) each time you miscount. However, unlike most other compulsions, counting crops up almost anywhere, anytime. In Chapter 8 and elsewhere, we warn about not attempting to suppress obsessive thoughts because they will merely increase if you do. However, counting is a mental compulsion that is designed to decrease anxiety and distress. Troubling touching can consist of constant tapping of fingers in certain sequences, touching every third railing and needing to go back if one is missed, tapping wood ritualistically, rubbing smooth or rough surfaces over and over, or complicated combinations of foot tapping and hand movements. Motor tics involve quick, uncontrollable movements of various types, but are usually not accompanied by obsessive thoughts. Spend a day or two noticing all the ways in which you ritualistically touch, tap, or rub various items or surfaces. Expect some discomfort at first, and be aware that the discomfort is highly likely to decrease as you continue. You will probably find it useful to start by not engaging in your compulsive touching for an hour or so. Compulsive doodlers sometimes have favorite themes for their doodling, such as circles, weapons, or mazes. Those with a doodling problem often become so wrapped up in their doo dling that the rest of the world is shut out. Some office workers doodle their days away and run into trouble with their supervisors for a lack of productivity. The techniques for doing away with doodling look much like the strategies we outline for counting and touching earlier in this chapter. Doodling in different ways Change your doodling patterns in every way you can think of. Most people who doodle compulsively have preferred pens, pencils, paper, designs, and patterns for their doodling. The strategy of just saying no to doodling demands increasing amounts of time in which you consciously resist the urge to doodle. You slowly build up your tolerance while taking notes, working on your tasks, and so on. Getting ready for work can require two or three hours, making you chronically late for work. Typically, their slowness represents an attempt to reduce their doubts and uncertainty and/or obtain perfection. A few neurological disorders include symptoms of motor slowness as a prominent feature. If you or someone you love demonstrates problems with compulsive slowness, check it out with your family doctor, who may choose to refer you to a neurologist. However, you can address the issues of doubting, uncertainty, and perfectionism (which frequently drive this problem) by working carefully through Chapter 8. However, most people who live in slow motion are looking for certainty and perfection. He is gifted, but graduated from high school with only mediocre grades because of his compulsive slowness. However, this note-taking strategy prevents him from getting much of the important material on paper. He passed high school because he was bright enough to get away with this inefficiency. His slowness also bogs him down because he reads and rereads all his textbook assignments out of fear of not understanding everything. Then write down the average of their reports and make it your goal to meet or beat those lengths of time. Review your own particular slowness issues and try to design some common-sense solutions. Tics are repetitive, rapid vocalizations or movements that are difficult to suppress. Such noises include grunts, groans, barks, and swear words, whereas movements may involve rapid head jerks, eye blinks, facial grimaces, and so on. However, some people with these habits report engaging in them as a way of reducing distress, so the distinction may not hold for everyone. In this chapter, we review the primary strategies for undoing these problem atic behaviors and habits. Most importantly, we tell you about a treatment that was developed in the 1970s by Drs. We conclude with a discussion of important thinking habits to acquire in order to succeed and maintain your gains. These problem areas include body dysmorphic disorder, eating disorders, patho logical gambling, kleptomania, hypochondriasis, pyromania, and various paraphilias. If one of these problems seems to apply to you, we recommend that you seek professional help. They are well-ingrained habits, and most people have them for years before they attempt to change them. Many people report that they are almost completely unaware of when they have tics, pull their hair, or pick at their skin. Learning how to relax as a way of handling stressors that sometimes set off problematic behaviors and habits. Some professionals used to believe that if you eliminated problematic behav iors such as tics and hair pulling, you would simply find another bad habit to replace it.

Still another type of eating disorder is rumination disorder in which infant or child regurgitates and rechews food after it has been swallowed treatment for sinus infection toothache discount bactrim 960mg on-line. Each of these disorders lasts for a month and is not associated with transient stomach distress virus informaticos order bactrim with visa. Tic Disorders: Tic is defined as a rapid antibiotic for sinus infection and sore throat generic 960mg bactrim with amex, recurring involuntary movement or vocalization bacterial bloom order 960 mg bactrim mastercard. Some important tics include motor ticks such as eye blinking antibiotics low blood pressure trusted bactrim 960 mg, facial twitches and shoulder shrugging antibiotics for sinus infection during breastfeeding purchase bactrim without a prescription. Besides motor movements, tics can also involve vocal tics such as coughing, grunting, snorting, coprolalia (uttering of obscenities) and tongue clicking. In some cases individuals engage in complex bodily movements involving touching, squatting, twirling or retracing steps. Individuals with this disorder also have obsessive-compulsive symptoms, speech difficulties and atentional prblems. Elimination Disorders: In this disorder children have difficulties in gaining control over their toilet. Some children with this disorder do not initiate social interactions or respond when it is inappropriate. Frequent changes in the caregiver, such as frequent parental divorce followed by remarriages or change in the care giver, etc. Stereotypic Movement Disorder: Children with this disorder engage in repetitive behaviours such as waving, body rocking, head banging, self-biting, etc. Selective Mutism: In selective mutism, the child consciously refuses to talk in certain situations, usually when there is an expectation for interaction such as at school. It requires considerable skills and a multiple approaches which takes in to account, biological, psychological and social factors. There is considerable debate among researchers and clinicians as to whether separate diagnostic categories should exist for children for development-related disorders or other disorders. Cognitive functions include processing of thought, memory capacity and ability to pay attention. The cognitive disorders that we will discuss in the following pages have following three central characteristics: It involves impairment of thoughts Loss of or problems in memory Difficulties in attention Impairment can result due to brain trauma, disease or exposure to toxic substances (including drugs). Impairment of cognitions can be assessed through neurophysiological testing and through development of new neuroimaging technologies. However inspite of advancements in sophisticated diagnostic tools, neuropsychological assessment has assumed greater importance to determine as to whether cognitive disorder is a result of organic impairment or whether it is a result of psychological factors. In delirium individual experiences cognitive 226 changes in which their memory is foggy and they are disoriented. A person in a state of delirium may forget what he or she had eaten for lunch only an hour earlier or be unaware of the day of the week or even the season of the year. The speech of the individual experiencing delirium may be rambling or incoherent as they shift from one topic to another. Some other major characteristics of delirium are as follows: Individuals having delirium may experience delusion, hallucinations or illusions as well as emotional disturbances such as anxiety, euphoria or irritability. Delirious individuals may do things that are physically dangerous, such as walking in to traffic or falling down the stairs. Delirium can be caused by substance intoxication or withdrawal, head injury, high fever, vitamin deficiency, etc. Delirium can occur at any age but it is more common among medically or psychiatrically hospitalized older adult patients, particularly among surgical patients with pre-existing cognitive impairment and depressive symptoms. Psychomotor disturbances related to delirium can be either hyperactive or hypoactive. Hypoactive individuals are slowed down, acting in ways that reflect their feelings of lethargy and stupor. Hallucinations, delusions and agitation are more likely to occur in the hyperactive phase. Patients and their relatives must be educated about its symptomatology, early prevention and diagnosis. Awareness about delirium and early intervention can help the patients to overcome many negative consequences. People with amnestic disorders are unable to recall previously learned information or to register new memories. The inability to incorporaterecent events into memory or to recall important information can be very disturbing, because an individual loses a sense of personal identity. In amnestic disorder an individual may try to cover up social problems caused by memory loss through denial or confabulation, the fabrication of facts or events to fill a memory void. Wide variety of medical conditions such as head trauma, loss of oxygen, or herpes simplex or environmental toxins like lead, mercury, pesticides, industrial toxins, etc. Memory loss, due to any reason in this disorder can result from damage to subcortical regions of the brain responsible for consolidating and retrieving memory 13. Intense pressure to head as a result of fall, automobile accident sports injury, combat, etc. It is estimated that in war, such as Afghanistan War and Iran War about 22 % of the soldiers suffered from brain injury. Some important brain injuries that result due to brain trauma include: Concussions It is caused by a blow to the head. Contusions Cereberal infarcations (cutting off of blood) Intrusion in to brain by fragments of bullets, instruments, iron rods,e tc. Some important symptoms of Traumatic Brain Injury include: headaches, sleep disturbances, sensitivity to light and noise and diminished cognitive performance on tests of attention, memory, language and reaction time. Symptoms also include depression, anxiety, emotional outbursts, mood changes or inappropriate affect. Individuals suffering from Traumatic Brain Injury often experience subtle changes that are note easily observable to themselves or to others. Post-Concussion Syndrome: It is a disorder arising out of concussions in which a constellation of physical, cognitive or emotional symptoms persists from weeks to years. Physical Cognitive Symptoms Emotional Symptoms Symptoms Headaches Confusion Irritability Dizziness Concentration Mood Sleep difficulties swings disturbance Impaired Depression Sensitivity to judgment light and Amnesia noise 228 13. Besides cognitive changes people with dementia experience changes in personality and emotional state. Some important characteristics of dementia are as follows: Initially in the earlier stages the disorder may begin with mild forgetfulness that is only slightly noticeable and annoying. Gradually their symptoms become increasingly obvious and severe As their condition worsens, they gradually loose their capacity to care for themselves. As their conditions worsen they are unable to remember even the basic facts about themselves and their lives. The individual knows the rules of sentence construction and can grasp the meaning of language, but he/she is unable to produce complete sentences In Apraxia a person has lost the ability carry out coordinated bodily movements that he or she could previously perform without difficulty. This is not due to physical weakness or decreased muscle tone, but due to brain deterioration. Disturbances in Executive Functioning: Dementia also leads to disturbances in executive functioning, which includes cognitive abilities, such as abstract thinking, planning, organizing or carrying out behaviours. The term senile is sometime, mistakenly, used to refer to this disorder, or more generally to the process of growing old. In Mumbai alone there are an estimated of about 40,000 individuals having this disorder. Alois Alzheimer At a scientific meeting in November 1906, German physician Alois Alzheimer presented the case of Frau Auguste D. Auguste had developed problems with memory, unfounded suspicions that her husband was unfaithful, and difficulty speaking and understanding what was said to her. Under the microscope, he also saw widespread fatty deposits in small blood vessels, dead and dying brain cells, and abnormal deposits in and around cells. The condition entered the medical literature in 1907, when Alzheimer published his observations about Auguste D. In 1910, Emil Kraepelin, a psychiatrist noted for his work in naming and classifying brain disorders, proposed that the disease be named after Alzheimer. The resulting symptoms start with memory loss and other cognitive deficits, advancing to major personality changes and eventual loss of control over bodily functions. Forgetting recently learned information is one of the most common early signs of dementia. A person begins to forget more often and is unable to recall the information later. Individuals may lose track of the steps involved in preparing a meal, placing a telephone call or playing a game. They may be unable to find the toothbrush, for example, and instead ask for "that thing for my mouth. They may show poor judgment, like giving away large sums of money to telemarketers. They may become extremely confused, suspicious, fearful or dependent on a family member. Physical conditions such as infectious diseases such as neurosyphilis, encephalitis, tuberculosis, meningitis or localized infections in the brain can result in dementia. People who experience kidney failure may have symptoms of dementia as a result of toxic accumulation of substances that the kidneys cannot cleanse from the blood. People with certain types of brain tumors also experience cognitive impairments and symptoms of dementia. Environmental toxins or ingestion of substances such as drugs can also lead to dementia, such dementia is called as Substance-induced persisting dementia. People who are severely undernourished are prone to develop a deficiency of folate, a critical nutrient, which can lead to progressive cerebral atrophy. It is caused by the accumulation in neurons of unusual proteins deposits called pick bodies. Individuals with this disease are socially inhibited, have memory loss, they act impulsively or inappropriately. About 60 % of the individuals who are older and are in the advanced stage of the disease experience dementia. Lewy body Dementia is diagnosed when lewy bodies are found more diffusely dispersed throughout the brain.

Processos de fabricacao para biofarmaceuticos sao altamente complexos e requerem centenas de passos de purificacao e isolacao especificas vyrus 987 c3 4v purchase bactrim 960 mg overnight delivery. Dessa forma infection quality control order bactrim 480 mg with mastercard, e impossivel produzir uma copia exata de um biofarmaceutico m4sonic - virus generic 960mg bactrim fast delivery, visto que mudancas na estrutura da molecula podem ocorrer com mudancas no processo de producao antibiotic resistance hsc buy bactrim 480mg amex. Uma proteina pode ser modificada de varias maneiras: cadeias laterais podem ser adicionadas antibiotic resistance journal buy bactrim with mastercard, o produto pode ter alteracoes em sua estrutura quartenaria ou terciaria atraves de ma dobradura da proteina entre outras antibiotics for sinus infections in adults discount bactrim 960mg without prescription. Como o protocolo de fabricacao e geralmente 33 uma propriedade da companhia de origem, e impossivel para um fabricante de biosimilar duplicar o processo. Isso torna o processo de fabricacao extremamente desafiador, visto que diferentes processos de fabricacao podem invariavelmente conduzir a diferencas estruturais no produto final. Por sua vez, essas diferencas podem levar a mudancas na eficacia e, mais essencialmente, em sua habilidade de acionar respostas imunes em pacientes. Avaliando a biosimilaridade Copias exatas de farmacos sinteticos (pequena molecula) podem ser sintetizadas e consideradas equivalentes se tiverem a mesma estrutura quimica, composicao e perfis farmacocineticos das drogas originais. Atraves de um processo de producao inteiramente diferente, os fabricantes de biosimilares so podem usar uma molecula que e similar, mas nao identica ao produto de origem. Um desafio para os fabricantes de biosimilares e demonstrar que seus produtos tem suficiente semelhanca com o produto original, alem de mostrar consistencia de qualidade entre diferentes sequencias de producao durante a fabricacao. A manutencao de uma eficacia consistente do produto e tambem importante para evitar super-dosagem do produto e riscos concomitantes de eventos adversos incidentes. Biofarmaceuticos podem ser tao extensos quanto centenas de kilodaltons, e seus pesos moleculares podem variar ate 1000 daltons. Varios testes in vitro sao comumente utilizados para comparar os aspectos estruturais de biosimilares com suas moleculas originais incluindo determinacoes de sequencias de aminoacidos, carga e propriedades hidrofobicas. Apesar das similaridades em tamanho e estrutura, pode haver diferencas significativas na atividade biologica. Alem disso, atividade biologica in vivo pode tambem ser afetada na formulacao do produto e acondicionamento, alem de manuseio de cadeia fria, visto que esses parametros podem influenciar a presenca de impurezas e agregados da proteina. Alem disso, a atividade biologica e dificil de determinar adequadamente, visto que poucos (se alguns) modelos animais sao capazes de fornecer dados que possam ser extrapolados para uma previsao apurada de atividade biologica em humanos. Em ultima analise, testes 34 clinicos controlados permanecem sendo os meios mais seguros de demonstrar similaridade entre uma molecula biosimilar e o produto original na pratica clinica. Entretanto, os testes clinicos podem ser subpotencializados para detectar complicacoes iatrogenicas infrequentes. Os problemas da imunogenicidade A preocupacao mais critica com seguranca relacionada aos biofarmaceuticos e a imunogenicidade. Todos os biofarmaceuticos sao moleculas biologicamente ativas derivadas de celulas vivas e tem o potencial para evocar uma resposta imune. Embora o potencial imunogenico nao possa ser previsto atraves de analises estruturais ou quimicas dos biofarmaceuticos, varios fatores conhecidos afetam o potencial imunogenico do produto. A presenca de impurezas no produto final, modificacoes estruturais como resultado do processo de fabricacao e/ou condicoes de estocagem podem aumentar a imunogenicidade. Procedimentos de controle de qualidade integrados no processo de fabricacao sao de suma importancia para assegurar a fabricacao de produtos seguros de qualidade consistente. Os riscos de imunogenicidade podem ser reduzidos atraves de testes rigorosos do biofarmaceutico durante seu desenvolvimento. Muitos dos testes sao realizados in vitro, mas alguns modelos animais sao empregados sabendo-se que muitas reacoes imunogenicas sao especificas da especie. Todos esses testes podem dar uma ideia do potencial antigenico de um biofarmaceutico, mas nao podem prever seus efeitos imunogenicos num paciente individualmente. Para uma comparacao consistente de resultados, todos os ensaios usados precisam ser padronizados de acordo com normas e recomendacoes internacionais. O unico meio de estabelecer seguranca de um biofarmaceutico e atraves de testes clinicos. O monitoramento a longo prazo dos efeitos em pacientes deve ser empreendido para avaliar adequadamente 35 os efeitos imunogenicos de qualquer biofarmaceutico introduzido no mercado. A imunogenicidade ja provou ser problematica para alguns biofarmaceuticos ja introduzidos no mercado. Um exemplo que ilustra as graves consequencias de pequenas mudancas no processo de fabricacao e a que envolve a epoetina alfa. Este medicamento e utilizado para o tratamento de pacientes com anemia secundaria a doenca renal cronica, visto que esses individuos sao incapazes de produzir quantidades consideraveis de eritropoetina endogena. Uma minima mudanca na formulacao desse produto de epoetina alfa resultou no desenvolvimento de anticorpos neutralizadores, nao apenas a droga em si, mas tambem a eritropoetina nativa em alguns pacientes. Muitos pacientes desenvolveram anticorpos anti epoetina que neutralizaram ambas, a eritropoetina endogena e a epoetina injetavel tornando a medula ossea aplastica para as celulas progenitoras eritropoeticas. Embora a causa real dessa reacao imunogenica permaneca desconhecida, uma hipotese e que lixivias resultantes de interacoes entre tampoes de borracha descobertos e um novo estabilizador utilizados na formulacao do produto poderiam ter levado a producao de anticorpos em alguns pacientes. Seja qual for a causa verdadeira, esse caso realca o potencial impacto catastrofico que minimas mudancas na fabricacao podem causar e as dificuldades na producao e formulacao de biofarmaceuticos. Se as moleculas biosimilares sao fabricadas utilizando-se um processo completamente diferente daquele dos produtos originais, resultando em diferencas bioquimicas e estruturais na molecula original, como pode a seguranca delas ser garantida sem um extenso teste clinico Pacientes que substituem o medicamento biologico original para um produto similar, mas nao identico, podem ter consequencias importantes. Quando defrontados com a possibilidade de substituir uma droga original por um produto biosimilar, e importante considerar cuidadosamente os riscos potenciais para o paciente por exemplo, aqueles relacionados a uma resposta imunogenica para uma molecula diferente. Fabricantes e medicos sao encorajados a fornecer informacao a todos os depositarios (incluindo pacientes, farmaceuticos e outros cuidadores) fornecendo uma avaliacao clara dos riscos envolvidos na troca de um produto estabelecido para seu biosimilar equivalente. A tolerancia de risco dependera provavelmente de fatores socioeconomicos e individuais, tais como a gravidade da doenca em questao e a politica de reembolso de saude local. Reducao no preco da droga pode ser um fator importante a se considerar em paises em desenvolvimento, ao passo que a seguranca do paciente e lealdade a marca podem ser os principais fatores em paises desenvolvidos. Conclusoes Ao contrario de drogas genericas, biosimilares nao sao identicos aos seus produtos de origem. A natureza altamente imprevisivel de respostas imunes aos biofarmaceuticos solicita testes apropriados aos biosimilares baseados em fundamento cientifico e evidencia experimental rigorosa. A entrada de biosimilares no mercado farmaceutico como opcao terapeutica alternativa permanece aberta a especulacao. Medicos, farmaceuticos, convenios de saude e pacientes precisarao comparar possiveis economias nos custos de medicacoes biosimilares versus o risco de complicacoes iatrogenicas. Neste artigo de revisao, os autores detalham alguns problemas terapeuticos que surgem quando uma paciente com epilepsia em tratamento fica gravida e precisa do controle adequado das crises bem como de atencao para a seguranca fetal. Epidemiologia: A prevalencia de mulheres com epilepsia e gestantes pode atingir ate 0. Entretanto, a exposicao fetal as medicacoes antiepilepticas tem aumentado uma vez que estas medicacoes vem sendo utilizadas para outras patologias como disturbios psiquiatricos, cefaleia e alteracoes neuropaticas dolorosas. Efeitos da gestacao na epilepsia: A gestacao nao afeta o controle das crises na maioria das mulheres com epilepsia. As flutuacoes na frequencia de crises observadas durante a gestacao podem ser secundarias as alteracoes na farmacocinetica das medicacoes neste periodo. Efeitos das crises na gestacao: As crises tonico-clonicas generalizadas podem aumentar a pressao sobre o utero e levar ao trauma se a paciente cair. Entretanto, provavelmente a maior causa de morbimortalidade nesta populacao e a interrupcao do uso da medicacao. Estudos indicam que as crises nao contribuem para uma maior taxa de anormalidades congenitas. Cesariana e necessaria geralmente quando ocorrem frequentes crises tonico-clonicas generalizadas ou quando as crises comprometem a cooperacao da paciente durante o trabalho de parto. Este risco aumenta quando o tratamento e realizado em politerapia e os riscos com a monoterapia parecem ser dose dependente. Em especial, o valproato esta associado a uma maior incidencia de teratogenese grave (defeitos do tubo neural) principalmente quando utilizado em altas dosagens. No entanto a suspensao abrupta desta medicacao nao e aconselhada, uma vez que na maioria das vezes o fechamento do tubo neural ja ocorreu quando a gravidez e percebida. Como monitorizar o tratamento e alterar doses: As concentracoes das medicacoes antiepilepticas diminuem com o decorrer da gravidez. O aumento das dosagens deve ser considerado precocemente se houver sinais clinicos de piora no controle das crises. Planejamento gestacional: Gestacoes nao planejadas geralmente sao tardiamente descobertas (posterior a 5-11 semanas). Deste modo, nestas circunstancias nao ha necessidade de alterar a medicacao antiepileptica. O uso de acido folico (ate 5mg/dia) e recomendado antes da concepcao ate o fim do primeiro trimestre. Manuseio obstetrico e amamentacao: Devido ao risco (apesar de pequeno) de teratogenese das medicacoes antiepilepticas, estas mulheres necessitam de um pre-natal mais cuidadoso especialmente quando apresentam crises refratarias. Utilizando a ultra sonografia, quase todos os defeitos do tubo neural podem ser diagnosticados com 12-22 semanas de gestacao. Introducao: O sono exerce influencia bem conhecida sobre as descargas epileptiformes. Entretanto, o efeito desta influencia sobre o valor localizatorio das descargas ictais ainda foi pouco investigado. Alguns relatos indicam que em pacientes com epilepsia de lobo temporal, as crises durante o sono apresentam maior tendencia a generalizacao secundaria. Introducao: Com o desenvolvimento das tecnicas de investigacao de pacientes com epilepsia, sobretudo a ressonancia magnetica de alta resolucao o diagnostico de displasia cortical focal passou a ser mais frequente. Alguns estudos descrevem taxas de remissao de crises apos o tratamento cirurgico desta patologia variando de 40 ate 86%. Este estudo descreve a avaliacao a longo prazo em pacientes com a mesma histopatologia. Dos 49 pacientes incluidos, 23 pacientes (47%) estavam completamente sem crises desde a cirurgia e 4 (8%) pacientes apresentavam apenas auras. Durante os 10 anos de seguimento, a proporcao de pacientes com evolucao satisfatoria diminuiu, principalmente dentro dos 3 primeiros anos. Durante o seguimento a longo prazo, 48% pararam com o tratamento medicamentoso, 34% receberam habilitacao para dirigir e 57% encontraram emprego. Conclusao: O tratamento cirurgico de epilepsias secundarias a displasia cortical focal e bem sucedido tanto a curto como a longo prazo. Este indice de sucesso permanece constante principalmente apos o terceiro ano de seguimento. Entretanto, estes resultados nao estao necessariamente associados a uma melhor carreira profissional ou melhora na qualidade de vida. Trata-se de um excelente artigo de revisao sobre o uso do corticoide nas distrofias musculares no qual o autor faz uma revisao historica dos ensaios clinicos e da evidencia de beneficio do uso do corticoide nesta patologia. Nas criancas que mantem sua capacidade de deambular e naquelas em cadeiras de rodas, o corticoide mostrou-se eficaz na melhoria da forca muscular e em varios parametros funcionais, tais como manutencao da capacidade de deambular. Alguns meninos tiveram sua capacidade deambulatoria mantida por anos alem do que seria esperado na evolucao natural da doenca. Os efeitos foram semelhantes, porem o deflazacort esteve menos associado a efeito colateral, principalmente o ganho de peso. Nao se sabe exatamente qual o mecanismo de acao do corticoide mas postula-se que seja capaz de regular a transducao do sinal nuclear com acao em alvos genomicos e proteomicos ainda nao identificados. Outra acao possivel seria reducao de necrose e inflamacao e a possibilidade ainda de induzir a proliferacao de mioblastos auxiliando na regeneracao muscular. A dose estabelecida como eficaz nos diferentes estudos foi a de 0,75 mg / Kg de peso para a prednisona e de 0,9mg/Kg para o deflazacort. Os efeitos colaterais sao revistos e um guia para prevencao do surgimento dos mesmos e fornecido, e baseado principalmente no controle dietetico, suplementacao com vitamina D, calcio, e atencao ao peso, altura, pressao arterial e niveis glicemicos, entre outros. O autor termina fazendo uma revisao das novas possibilidades terapeuticas, que sao: terapia genica, inibicao da miostatina por anticorpos especificos, upregulation da urotropina, uso de celulas pluripotenciais, terapias essas em fase I de estudo, ou anterior, sendo apenas o corticoide o padrao ouro atual para o tratamento desta condicao. Geralmente ocorre em topografia bifrontal e acompanha-se de alargamento da fissure interhemisferica, sendo os ventriculos de tamanho normal ou levemente aumentado. Portanto, espera-se uma resolucao do aspecto radiologico do quadro atraves do amadurecimento destas vilosidades por volta de 18-24 meses de idade, embora em geral a crianca permaneca macrocefalica ao longo da vida. A recorrencia familiar da macrocefalia e um dado que deve ser valorizado nestes casos benignos, ocorrendo muito frequentemente. Excepcionalmente as criancas que apresentam o quadro podem cursar com um leve atraso motor transitorio devido ao aumento do segmento cefalico. Considera que para evitar interpretacoes erroneas, o radiologista deve estar atento ao estado de hidratacao e nutricao, alem eventual concomitancia com hipomagnesemia, bem como com cortico ou quimioterapia. O diagnostico precoce de algumas destas entidades e muito importante para aquelas nas quais novas estrategias terapeuticas estao surgindo, tais como algumas formas de mucoplissacaridoses e aciduria glutarica tipo I. Apesar do progresso cientifico que tornou as vacinas cada vez mais eficazes e seguras, continua a existir na midia uma publicidade negativa que tem afetado a taxa de vacinacao das criancas e expondo-as ao possivel efeito devastador de algumas doencas infecciosas. Em relacao as vacinas utilizadas na atualidade, a incidencia de crises febris e mais baixa e nao ha indicios conclusivos de que sejam inerentemente epileptogenicas ou causem encefalopatias. Esta revisao avalia tres situacoes que relacionam as vacinas com efeitos neurologicos adversos: o risco de crises epilepticas desencadeadas pela vacinacao, a encefalopatia pos-vacinal e as alteracoes de comportamento do espectro do autismo que comumente se associam a crises epilepticas e tem sido atribuidas a determinados esquemas vacinais. O autor enfatiza que nao ha ainda uniformidade entre os estudos que avaliam os efeitos adversos das vacinas porque nos paises em desenvolvimento, devido a problemas de custo, ainda nao existe amplo acesso as novas e mais seguras vacinas que estao sendo utilizadas nos ultimos 15 anos, tais como o esquema triplice no qual o componente anti-pertussis inclui o antigeno acelular e o esquema polivalente difteria/tetano/ pertussis acelular/hepatite B/polio inativado/Haemophilus influenzae tipo B, no qual foram aperfeicoados numero e concentracao de antigenos, bem como dos componentes aditivos. O calculo do risco de crises febris ocorrendo nas primeiras 72 horas apos a vacinacao deve levar em conta a possibilidade de se tratar de criancas ja predispostas e em uma idade em que ha alta possibilidade de episodios infecciosos febris ocorrendo independentemente da vacinacao em si. Nao ha estudos comparando o risco de crises febris em criancas em estado pos-vacinal e em criancas que estao febris por outras causas. Adicionalmente, o novo esquema acelular da vacinacao antipertussis tem diminuido substancialmente a ocorrencia de febre pos-vacinal e o risco de crises febris passou de 1:2250 com o antigo preparado para 1: 20000 com o novo tipo. O risco de recorrencia das crises febris ou de desenvolvimento de epilepsia bem como 48 de afeccoes neurologicas posteriores e o mesmo em criancas que tiveram a primeira crise febril com e sem associacao com a vacinacao. O diagnostico de crises febris nao deve ser considerado contra-indicacao para a vacinacao, embora a febre possa desencadear uma crise. Entretanto, em criancas que estejam apresentando um quadro neurologico em evolucao e ainda nao diagnosticado, a vacinacao antipertussis costuma ser adiada ate ocorrer estabilidade do quadro, embora nao haja evidencias concretas para esta recomendacao.

Deep muscle-relaxation training and pairing of relaxation and imagined scenes are depicted. Part of a series of case histories, this video explores the symptoms and experience of being obsessive-compulsive. The film uses compulsive behavior to illustrate how irrational thinking leads to self-defeating behavior and exaggerated fears. Defense mechanisms are shown, as well as means for exploring and facing them so as to reduce neurotic symptoms. A disturbed office worker experiences panic and terror when he is unable to suppress his hostilities. Judith Rapport, author of the book by the same title considers symptoms, diagnosis, and possible cures. Dissociative disorders dissociative amnesia, dissociative fugue, dissociative identity disorder (multiple personality), and depersonalization disorder A. Most are rare, but reports of dissociative identity disorder in United States have increased B. Dissociative amnesia: partial or total loss of personal information (due to traumatic event) 1. Dissociative fugue: dissociative amnesia plus travel; usually incomplete change of identity; recovery usually abrupt and complete D. Characteristics a) Two or more independent personalities exist in one person b) One personality evident at a time; usually amnesia in personality that is not present, although personalities may have awareness of other personalities c) Often opposite personalities d) More prevalent in women in United States, but no gender differences found in Switzerland e) Conversion symptoms, depression, and anxiety are common 2. Hard to separate faking from real; reliable diagnostic methods do not currently exist 2. Behavioral perspective a) Avoidance of stress by indirect means b) Iatrogenic or therapist-produced G. Three-part group format a) Psychoeducation b) Use of group resources c) Develop cognitive and social skills 3. Depersonalization disorder has slower rate of spontaneous remission, so treatment focuses on relieving anxiety, depression, or fear of going insane 5. Undifferentiated somatoform disorder: not fully meeting criteria, but at least one physical complaint for six months 3. Overall prevalence rate of 2 percent; more prevalent among females and African Americans C. Differentiate from physical by lack of atrophy in paralyzed extremity, neurological impossibility (glove anesthesia), relation to stress 3. Characteristics: severe or excessive pain with no physiological basis or long after injury has healed 2. Pain is complex phenomenon with both physiological and psychological bases, but descriptions of the pain and its location are vague. Characteristics: preoccupation with health, anxiety and depression; reassurance has no impact 2. Predisposing factors: history of physical illness, parental attention to somatic symptoms, low pain threshold, greater sensitivity to somatic cues F. Diagnostic problems a) Normal dissatisfaction with appearance high (46 percent of college students have some preoccupation with appearance) b) Overlap with delusional disorder or obsessive-compulsive disorder G. Diathesis-stress: hypervigilance and sensitivity to body sensations followed by stressor 2. Psychodynamic perspective a) Repression of conflict converted to physical b) Primary gain: protected from anxiety c) Secondary gain: attention and dependency needs met 3. Behavioral perspective a) Assume sick role for reinforcement/avoidance b) Modeling important c) Fordyce (1988) reports physicians unwittingly reinforce; male patients with supportive wives experience more pain when wife is present 4. Biological perspective a) High arousal levels, higher sensitivity to bodily sensations H. Psychodynamic treatment a) Psychoanalysis to relive feelings associated with repressed event b) Hypnotherapy 2. Discuss the fundamental characteristics involved in dissociative disorders, and list the four types of dissociative disorders. Discuss the characteristics of the four types of dissociative amnesia and the process by which they occur. Describe the characteristics of dissociative fugue and depersonalization disorder. Describe the characteristics of dissociative identity (multiple personality) disorder and its prevalence. Discuss and distinguish the psychodynamic, behavioral, and iatrogenic (therapist-produced) explanations for dissociative disorders. Discuss the treatment of dissociative amnesia and fugue, depersonalization disorder, and dissociative identity disorder. Describe the basic characteristics of somatoform disorders and distinguish them from malingering and factitious disorders. List and describe the five subtypes of somatoform disorder, including somatization disorder, conversion disorder, pain disorder, hypochondriasis, and body dysmorphic disorder. Describe and discuss the causes of somatoform disorders from the psychodynamic, behavioral, sociocultural, and biological perspectives, and the diathesis-stress model. Describe and discuss the treatment of somatoform disorders with psychoanalytic, behavioral, and family systems therapies. Dissociative identity disorder (multiple personality) is a favorite topic for discussion and evaluation because it is so bizarre and dramatic. One way of clarifying the difference is to draw a set of partially interconnected circles on the board to show the relatively distinct components that make up multiple personality and a dotted circle next to these to indicate the fractured nature of schizophrenia, where not even one intact personality is found. Once these differences are established, it is useful to examine the functions of separate personalities for a person who has endured prolonged physical or sexual abuse. The cases of Billy Milligan (Keyes, 1981), Sybil (Schreiber, 1973), and Jonah (Ludwig et al. Ask the class to imagine the events that might produce such dissociated personalities. Students who are skeptics of psychoanalysis are often impressed with this tripartite split among personalities. It even seems that Eve (who had some 21 faces before she was successfully treated) had personalities that came out in groups of three (Sizemore & Pittillo, 1977). Students can better understand the behavioral and family systems view on somatoform disorder by looking at the positive consequences of making somatic complaints. Ask students how many of them when they were younger faked or exaggerated illnesses to get out of difficult academic or interpersonal situations. Chapter 6: Dissociative Disorders and Somatoform Disorders 91 these complaints, and what effect did the reactions have If parents helped these children avoid responsibilities, we can expect that illness complaints increased in frequency. On the other hand, if parents routinely ignored such complaints, children probably learned to face responsibility. This discussion should raise questions about soft and hard-heartedness and the danger of parents wrongly suspecting fakery. This mirrors the dilemma of the physician or psychologist with a client who repeatedly complains of pain or other problems in the absence of a physiological explanation. Instructors can suggest a reasonable middle ground: that complaints need to be thoroughly checked out for possible physical causes before one assumes that there are other reasons. Even so, it is dangerous to assume that medical assessment has reached the zenith of accuracy. Therapists tend to spend more time thinking about these clients, consulting books and colleagues to better understand them, and paying attention to their subtle verbal and nonverbal messages. Like other people, clinicians become enthused by puzzles they have trouble solving. In some ways, it may be a disappointment to find an interesting case becoming an ordinary case, so some clinicians may inadvertently influence clients to exaggerate the symptoms of multiple personality. The opposite of this effect may also occur with clients whose problems seem more pesky than interesting. Conversations with hypochondriacal clients are continuous battles to steer the topic away from their health concerns. Boon and Draijer (1993) gave the Structured Clinical Interview for Dissociative Disorders, the Structured Trauma Interview, and the Dissociative Experiences Scale to 71 patients being treated for dissociative identity disorder. For each item, the percentage of the sample reporting or qualifying for that item is given. Multiple personality disorder in the Netherlands: A clinical investigation of 71 patients. Structured interview data on 102 cases of multiple personality disorder from four centers. Rabinowicz (1989) describes a way of demonstrating dissociative identity disorder in the classroom. Students take the Imagination Potential Scale, and the top three scorers are given the task of playing a serial killer interviewed by a court-appointed clinician. The role play is based on the Hillside Strangler murder case and highlights the issues of differentiating multiple personality from faking, as discussed in the text. Creating the multiple personality: An experiential demonstration for an undergraduate abnormal psychology class. The first controlled therapy outcome study on body dysmorphic disorder was published in 1995. Rosen, Reiter, and Orosan (1995) randomly assigned 54 body dysmorphic disorder subjects with to cognitive behavioral therapy or to a no-treatment control group. Their beliefs concerning the importance of physical appearance were challenged, they monitored and modified their thoughts about body dissatisfaction, and they practiced techniques for eliminating body checking. An exposure/response prevention component of treatment put subjects in situations they normally avoided because of concern over their appearance. Checking and intrusive thoughts were significantly reduced in treated subjects, and in 82 percent of cases the disorder was eliminated at posttreatment. Clearly this study indicates that cognitive-behavioral therapy can be useful in the treatment of body dysmorphic disorder. However, further studies comparing different approaches to treatment are needed to see if more effective and efficient methods can be found. When clinicians assume that somatic complaints are the result of somatoform disorders, they must be quite certain of their diagnosis. A false negative (failing to see an existing physiological condition) is a much more serious mistake than a false positive (claiming that a physiological condition exists when there is none). The wise psychologist makes sure that every conceivable medical test and specialist has been used prior to concluding that conversion disorder is the correct diagnosis. Consider this case presented by Fishbain and Goldberg (1991): A young man was in a fight when he was hit over the head with a bottle. He was reassured by hospital personnel and when given the direct suggestion that he was able to move the arm and leg, he moved them. Over a period of time, the patient continued to complain of an inability to move his left limbs, was reassured that he could, and showed movement.
