Assessment of memory complainers in São Paulo, Brazil: Three-year results of a memory clinic.

Memory clinics were established in the USA and European countries as services to attend patients who complain of cognitive deficits, referred by primary care doctors, specialists and other hospitals. OBJECTIVE: We aimed to describe the clinical and cognitive profile of consecutively evaluated subjects during the initial three years of service of a memory clinic from a university hospital. METHODS: Subjects were submitted to a clinical work-up for dementia, which included laboratory exams, cranial computerized tomography, cognitive tests, and a comprehensive neuropsychological battery. Diagnosis was made according to ICD-10 criteria. RESULTS: We evaluated 104 subjects (67.3% females and 32.7% males), with mean age of 59.1 years, 88.8% aged 50 years or above. Mean schooling was 9.9 years. Patients were classified into 10 different primary diagnostic categories, namely Depression (26.9%), Alzheimer's disease (17.3%), Memory complaints without objective impairment (17.3%), Mild Cognitive Disorder - MCD (14.4%), and Anxiety (12.5%) the most frequent diagnosis. Comparing patients with dementia, MCD, Depression or Anxiety and Memory complainers, by age (below and above 60 years), dementia was more commonly diagnosed in older subjects, while a higher frequency of memory complainers was found in the younger group. CONCLUSIONS: This preliminary report from an outpatient group of referred patients with cognitive complaints showed a higher frequency of psychiatric disorders in this sample. The memory clinic approach should be considered as a model of service which can evaluate subjects with cognitive complaints effectively and improve the quality of care delivered to this patient group.

Clínicas de memória foram estabelecidas nos EUA e em países europeus como serviços para atender pacientes que se queixam de déficits cognitivos, encaminhados por médicos em cuidados primários, especialistas e outros hospitais. OBJETIVO: Nós pretendemos descrever o perfil clínico e cognitivo de sujeitos consecutivamente avaliados nos primeiros três anos de funcionamento de uma clínica de memória de um hospital universitário. METÓDOS: Os sujeitos foram submetidos a avaliação clínica para demência, incluindo exames laboratoriais, tomografia computadorizada de crânio, testes cognitivos e uma bateria neuropsicológica completa. Diagnóstico foi feito segundo critérios da CID-10. RESULTADOS: Nós avaliamos 104 sujeitos (67,3% mulheres e 32,7% homens), com idade média de 59,1 anos, 88,8% com mais de 50 anos de idade. A escolaridade média era de 9,9 anos. Pacientes foram classificados em 10 categorias diagnósticas primárias diferentes, sendo Depressão (26,9%), doença de Alzheimer (17,3%), Queixas de memória sem comprometimento objetivo (17,3%), Transtorno cognitivo leve ­ TCL (14,4%), e Ansiedade (12,5%) as mais freqüentes. Comparando pacientes com demência, TCL, Depressão ou Ansiedade e aqueles com Queixa de memória, por idade (abaixo e acima de 60 anos), demência foi mais comumente diagnosticada nos idosos, enquanto maior freqüência daqueles com queixa de memória foi encontrada nos mais jovens. CONCLUSÕES: Este relato preliminar de pacientes ambulatoriais encaminhados com queixas cognitivas mostrou uma freqüência elevada de transtornos psiquiátricos nesta amostra. A abordagem da clínica de memória deveria ser considerada como um modelo de serviço para avaliar efetivamente sujeitos com queixas cognitivas, podendo melhorar a qualidade do cuidado prestado a estas pessoas.

Comparison of repetitive transcranial magnetic stimulation and electroconvulsive therapy in unipolar non-psychotic refractory depression: a randomized, single-blind study.

Repetitive transcranial magnetic stimulation (rTMS) can induce significant antidepressant effects and, for some patients, might be an alternative to electroconvulsive therapy (ECT). The results of studies comparing the efficacy of rTMS and ECT are mixed and, therefore, comparison of these two therapies needs to be further explored. Forty-two patients aged between 18 and 65 yr, referred to ECT due to unipolar non-psychotic depression refractoriness entered the trial. They were randomly assigned to receive either rTMS or ECT. Depressive symptom changes were blindly measured by Hamilton Depression Rating Scale, Visual Analogue Scale and Clinical Global Impression at baseline, after 2 wk and after 4 wk of treatment. There was no difference in the antidepressant efficacy of ECT and rTMS. Response rates were relatively low in both groups (40% and 50% respectively), with no significant difference between them (p=0.55). Remission rates were also low for both groups (20% and 10% respectively), also with no significant difference (p=0.631). There was no significant difference in the neuropsychological test performance after either one of these therapies. Both treatments were associated with a degree of improvement in refractory depression and therefore add to the literature that rTMS can be an effective option to ECT as it is a less costly treatment and is not associated with anaesthetic and other ECT risks.

Comparison of two regimens of a monthly injectable contraceptive containing dihydroxyprogesterone acetophenide and estradiol enanthate.

INTRODUCTION: This study compared two regimens of a monthly injectable contraceptive containing dihydroxyprogesterone acetophenide 150 mg and estradiol enanthate 10 mg (Perlutan) over 12 cycles of use. METHODS: Three hundred sixty-five adolescents were randomized into two groups. The patients in Group 1 received an initial injection of Perlutan on the 1st-5th day of their menstrual cycle and subsequent injections every 30 +/- 3 days, whereas those in Group 2 followed the traditional schedule of administration in which the first injection is administered between Days 7 and 10 of their menstrual cycle and subsequent injections 7-10 days after Day 1 of withdrawal bleeding. This schedule may result in an irregularity in the timing of injections. RESULTS: No significant difference was found between the two groups regarding tolerability or pregnancy (two in Group 1 and three in Group 2). CONCLUSION: Monthly administration limits the annual number of injections to a maximum of 12, thus frequently reducing the total annual dose while maintaining efficacy and tolerability similar to those obtained with the traditional regimen.

Transcranial magnetic stimulation accelerates the antidepressant effect of amitriptyline in severe depression: a double-blind placebo-controlled study.

BACKGROUND: Transcranial magnetic stimulation (TMS) is a noninvasive method to stimulate the cortex, and the treatment of depression is one of its potential therapeutic applications. Three recent meta analyses strongly suggest its benefits in the treatment of depression. The present study investigates whether repetitive TMS (rTMS) accelerates the onset of action and increases the therapeutic effects of amitriptyline. METHODS: Forty-six outpatients meeting DSM-IV criteria for nonpsychotic depressive episode were randomly assigned to receive rTMS (n = 22) or sham repetitive TMS (sham) (n = 24) during 4 weeks over dorsolateral prefrontal cortex (DLPFC) in this double-blind controlled trial. All patients were concomitantly taking amitriptyline (mean dose 110 mg/d). The rTMS group received 20 sessions (5 sections per week) of 5 Hz rTMS (120% of motor threshold and 1250 pulses per session). Sham stimulation followed the same schedule, however, using a sham coil. The efficacy variables were the Hamilton Depression Rating Scale-17 items (HAM-D/17), the Montgomery-Asberg Depression Rating Scale (MADRS), a Visual Analogue Scale (VAS), and the Clinical Global Impression (CGI). Tolerability was assessed by clinical examination and a safety screening of TMS side effects. RESULTS: Repetitive TMS had a significantly faster response to amitriptyline. There was a significant decrease in HAM-D/17 scores, already after the first week of treatment (p < .001 compared with baseline and p < .001 compared with sham). The decrease in HAM-D/17 scores in the rTMS group was significantly superior compared with the sham group throughout the study (p < .001 at fourth week). CONCLUSIONS: Repetitive TMS at 5 Hz accelerated the onset of action and augmented the response to amitriptyline.

Double-blind study to evaluate efficacy and safety of meloxicam 7.5 mg and 15 mg versus mefenamic acid 1500 mg in the treatment of primary dysmenorrhea.

OBJECTIVE: Assessment of efficacy and safety of meloxicam 7.5 mg and 15 mg once a day (o.a.d.) compared with mefenamic acid 500 mg three times a day (t.i.d.), over a treatment period of 3-5 days, during three menstrual cycles, for primary dysmenorrhea. STUDY DESIGN: Multicenter, multinational, double-blind, double-dummy, three parallel groups, randomized trial, phase IIb, 337 patients. Treatment group comparisons of continuous variables were carried out using the Kruskal-Wallis test and Wilcoxon signed rank tests. Efficacy was analyzed using Fisher and chi(2)-tests. RESULTS: Meloxicam 7.5 mg and 15 mg showed a similar profile in pain reduction and dysmenorrhea symptoms when compared with mefenamic acid. Thirty-five subjects presented with gastrointestinal (GI) adverse events (AEs). Two-thirds of those 35 subjects were in the mefenamic acid group. There were no differences between the safety profiles of the two meloxicam dosages. Laboratory abnormalities did not differ in incidence among the treatment groups. CONCLUSION: Both of the daily doses of meloxicam tested were comparable to 500 mg mefenamic acid t.i.d. in relieving dysmenorrhea symptoms, and meloxicam seems to have a better gastrointestinal tolerability profile.

Estimulação magnética transcraniana de repetição associada a antidepressivo: início e intensidade da resposta antidepressiva / Repetitive transcranial magnetic stimulation associated with antidepressant: start and intensive of the antidrepressant answer

OBJETIVOS: Avaliar diferentes estudos que analisam o grau de eficácia da resposta antidepressiva entre a associação de estimulação magnética transcraniana de repetição (EMTr) com antidepressivos em pacientes deprimidos graves. MÉTODOS: Os autores revisaram vários estudos em que a EMTr foi usada concomitantemente a antidepressivos em pacientes deprimidos graves. Adicionalmente, relatou-se um estudo feito no Instituto de Psiquiatria do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Estudo duplo-cego, randomizado, unicêntrico, placebo-controlado com 46 pacientes atendendo aos critérios diagnósticos da DSM-IV para episódio depressivo severo. Os pacientes estavam em uso de amitriptilina. RESULTADOS: De forma geral, a maioria dos estudos mostra que a EMTr apresenta boa eficácia antidepressiva quando associada a antidepressivos. Há grande diversidade de parâmetros técnicos utilizados, tipos de bobina, diferentes técnicas de placebo e uso de diferentes antidepressivos. O estudo realizado no Instituto de Psiquiatria mostrou que o emprego da EMTr de alta freqüência aumentou a resposta antidepressiva à amitriptilina e diminuiu o tempo para o início da resposta antidepressiva em relação ao grupo placebo. CONCLUSÕES: EMTr é um método novo, promissor e com grande potencial para o tratamento da depressão. Apesar disso, observa-se que não há ainda uniformidade no emprego dos parâmetros técnicos, nem tampouco das técnicas de placebo. O estudo realizado no Instituto de Psiquiatria do HC- FMUSP mostrou grandes taxas de resposta e remissão em relação ao grupo com estimulação sham e amitriptilna.

Eficácia e segurança do uso do inibidor seletivo da COX-2 versus antiinflamatório não esteróide clássico no tratamento sintomático da dismenorréia primária / Efficacy and safety of COX-2 selective inhibitor versus non selective NSAID in the symptomatic treatment of primary dysmenorrhea

Objetivo:Observação da eficácia e segurança do meloxican ( inibidor seletivo da COX-2) com ácido mefenâmico ( AINE clássico), por um periodo de três a cinco dias, durante três ciclos menstruais, para o tratamento da dismenorréia primária. Materiais e Métodos: Multicêntrico, internacional, duplo cego, paralelo, três grupos, randomizado, fase III b, 337 pacientes. AS variáveis contínuas dos grupos comparados foram analisadas através do teste de Kruskal-Wallis e Wilcoxon. Na avaliação da eficácia se utilizou o teste de Fisher e o qui-quadrado. Resultados : Meloxican 7,5 mg, 15 mg exibiu um perfil semelhante na redução da dor e dos sintomas da dismenorreia primário em comparação ao acido mefenamico. Quarenta e nove indivíduos apresentaram eventos adversos. Quase metade desses 49 pacientes eram do grupo que usou acido mefenamico. Não houve diferenças entre os perfis de segurança entre as duas dosagens de meloxican. As anormalidades laboratoriais não se diferenciaram entre os grupos estudados. Este estudo demonstrou que um AINE inibidor seletivo da COX-2 apresenta a mesma eficiência que um AINDE clássico porém com melhor perfil de tolerabilidade gastrintestinal.

Estimulação magnética transcraniana de repetição: potencializando o efeito de antidepressivos / Repetitive transcranial magnetic stimulation: augmenting the antidepressant drugs effect

Objetivos: O atraso no início da resposta terapêutica dos antidepressivos permanece como um problema no tratamento da depressão.A estimulação magnética transcraniana (EMT) é um método não invasivo que foi desenvolvido com a finalidade de explorar possíveis alterações comportamentais ligadas à estimulação cerebral e o tratamento de sintomas depressivos.Vários autores ao redor do mundo têm se dedicado ao estudo e na análise dos efeitos da EMT sobre os sintomas da depressão uma vez que alguns dos resultados dessa técnica ainda permanecem inconclusivos nessa indicação.Foi avaliada a ação antidepressiva e a diminuição do tempo para o início da resposta antidepressiva em 46 pacientes usando concomitantemente amitriptilina / OBJECTIVE: The delayed onset of therapeutic response to antidepressants remains a major problem in the treatment of depression. Transcranial magnetic stimulation (TMS) has been developed as a noninvasive method to explore brain-behavior relationships, and the treatment of depression is one of its potential therapeutic applications. The role of TMS in the treatment of depression has been studied by an increasing number of authors in the last decade. However, results from trials remain limited and inconclusive, and large scale studies are needed to establish the efficacy of TMS in the treatment of depression. We evaluated the short-term efficacy, safety and augmentation effect of repetitive pulses of TMS in 46 outpatients taking amytriptilin...

Electrocardiographic and blood pressure alterations during electroconvulsive therapy in young adults.

OBJECTIVE: To study cardiovascular alterations in young patients with no apparent organic disease who underwent electroconvulsive therapy. METHODS: The study comprised 47 healthy patients (22 males and 25 females) with a mean age of 30.3 years, who underwent electroconvulsive therapy. Ambulatory blood pressure monitoring and continuous electrocardiographic monitoring (Holter monitor) were performed during 24 hours. Blood pressure and heart rate were assessed 4 hours prior to electric shock administration, during electric shock administration, and 3 hours after electric shock administration. Arrhythmias and alterations in the ST segment in 24 hours were recorded. RESULTS: On electroconvulsive therapy, a significant increase in blood pressure and heart rate was observed and the measurements returned to basal values after 25 minutes. Three females had tracings with depression of the ST segment suggesting myocardial ischemia prior to and after electroconvulsive therapy. Coronary angiography was normal. No severe cardiac arrhythmias were diagnosed. CONCLUSION: 1) Electroconvulsive therapy is a safe therapeutic modality in psychiatry; 2) it causes a significant increase in blood pressure and heart rate; 3) it may be associated with myocardial ischemia in the absence of coronary obstructive disease; 4) electroconvulsive therapy was not associated with the occurrence of severe cardiac arrhythmias.
