OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital’s emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor’s office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

PURPOSE: To evaluate the impact of lower urinary tract symptoms (LUTS) on the quality of life (QoL) in a group of elderly men. MATERIALS AND METHODS: Observational clinical study contained 200 men recruited between March-September 2008 in the community and Urology and Geriatrics ambulatories. The data collected included health and sociodemographic conditions; the International Prostate Symptom Score (IPSS); an anxiety/depression inventory; the World Health Organization Quality of Life -Bref and -Old questionnaires (WHOQoL). Participants were classified according to IPSS: Group I (moderate/severe symptoms) and Group II (absence/mild symptoms) and 100 men were included in each group. RESULTS: The groups were statistically similar in sociodemographic, morbidity, and anxiety/depression scores. Both QoL scales showed significant lower median scores in group I in all parameters, except the global subjective self-evaluation of QoL. The domains social and environmental relations presented the most significative differences (p < 0.0005) in both questionnaires, and final mean WHOQoL-OLD score was lower in group I (p < 0.0005). CONCLUSIONS: For elderly men, moderate to severe LUTS do significantly impact almost all parameters of QoL proposed by the WHO, especially social and environmental relations.

JUSTIFICATIVA E OBJETIVOS: A osteoartrose (OA) é a artropatia mais comum e uma das principais causas de dor crônica na população idosa, podendo levar a grande incapacidade funcional nestes indivíduos. Objetivando o tratamento da dor em idosos com OA de joelho utilizou-se o clonixinato de lisina (CL) e avaliou-se a sua efetividade. MÉTODO: Estudo clínico e duplamente encoberto, aleatório e placebo controlado com 109 idosos com dor associada à OA de joelho. Os participantes foram divididos em dois grupos: Grupo CL e P (placebo) que receberam comprimidos para uso três vezes ao dia por 30 dias. Realizadas avaliações iniciais, após 15 dias e ao final do estudo, quanto à intensidade de dor em repouso, ao movimento inicial, à deambulação e à compressão articular; necessidade de analgesia complementar, rigidez matinal; incapacidade funcional associada à dor, aderência, tolerabilidade e avaliação global do tratamento. RESULTADOS: O CL reduziu significantemente a dor ao início do movimento e à deambulação já nos primeiros 15 dias, redução de 30% da dor protocinética e de 31,6% à deambulação, mas os melhores resultados ocorreram com 30 dias, quando as reduções foram de 42,3% e 45,5%, protocinética e à deambulação, respectivamente. A analgesia complementar foi significantemente menor com o CL: 2,6% e 9,5%, grupos CL e P, respectivamente. Não ocorreram diferenças entre os grupos para rigidez matinal e incapacidade funcional. Houve grande aderência e tolerabilidade. A avaliação global foi favorável para o CL, sendo excelente ou boa em 50%. CONCLUSÃO: O clonixinato de lisina foi efetivo no tratamento da dor associada à osteoartrite de joelho em idosos.

BACKGROUND AND OBJECTIVES: Osteoarthritis (OA) is the most common arthropathy and one of the major causes of chronic pain in the elderly population, which may lead to major functional incapacity of these individuals. Aiming at treating pain of elderly patients with knee OA, we have used lysine clonixinate (LC) and have evaluated its effectiveness METHOD: Randomized, double-blind, placebo-controlled clinical trial with 109 elderly patients with knee OA-related pain. Participants were distributed in two groups: Group LC and Group P (placebo), who received tablets to be used three times a day for 30 days. Evaluations were performed initially, 15 days after and at study completion, as to pain intensity at rest, at initial movement, ambulation and joint compression; and the need for additional analgesia, morning stiffness; pain-related functional incapacity, adherence, tolerability and global treatment evaluation. RESULTS: LC has significantly decreased pain at initial movement and ambulation already in the first 15 days, with 30% decrease in protokinetic pain and 31.6% in ambulation, but best results were seen after 30 days, when reductions were 42.3% and 45.5%, respectively. Additional analgesia was significantly lower with LC: 2.6% and 9.5% for groups LC and P, respectively. There were no differences between groups in morning stiffness and functional incapacity. There has been major adherence and tolerability. Global evaluation was favorable to LC, being excellent or good for 50% of patients. CONCLUSION: Lysine clonixinate was effective to treat knee OA-related pain in elderly people.

A influenza (gripe) é doença infecciosa aguda de origem viral que acomete o trato respiratório e a cada inverno atinge mais de 100 milhões de pessoas na Europa, Japão e Estados Unidos, causando anualmente a morte de cerca de 20 a 40 mil pessoas somente neste último país. O agente etiológico é o Myxovirus influenzae, ou vírus da gripe. Este subdivide-se nos tipos A, B e C, sendo que apenas os do tipo A e B apresentam relevância clínica em humanos. O vírus influenza apresenta altas taxas de mutação, o que resulta freqüentemente na inserção de novas variantes virais na comunidade, para as quais a população não apresenta imunidade. São poucas as opções disponíveis para o controle da influenza. Dentre essas, a vacinação constitui a forma mais eficaz para o controle da doença e de suas complicações. Em função das mutações que ocorrem naturalmente no vírus influenza, recomenda-se que a vacinação seja realizada anualmente. No Brasil, segundo dados obtidos pelo Projeto VigiGripe - ligado à Universidade Federal de São Paulo -, verifica-se que a influenza apresenta pico de atividade entre os meses de maio e setembro. Assim, a época mais indicada para a vacinação corresponde aos meses de março e abril. Para o tratamento específico da influenza estão disponíveis quatro medicamentos antivirais: os fármacos clássicos amantadina e rimantidina e os antivirais de segunda geração oseltamivir e zanamivir. Os últimos, acrescentam alternativas para o tratamento da influenza e ampliam as opções disponíveis para o seu controle.

Influenza (flu) is an acute contagious viral infection characterized by inflammation of the respiratory tract that every winter affects more than 100 million people in Europe, Japan and the United States of America, also being responsible for several thousand of excess deaths (data from the United States reveal between 20,000 to 40,000 excess deaths annually). The Mixovirus influenzae is the agent that causes influenza, commonly called flu. There are 3 types of influenza virus: A, B, C, and only types A and B are perceived to be clinically relevant in humans. Due to the segmented nature of its genetic material, the influenza virus is highly mutagenic, causing frequent insertion of new antigenic strains into the community, against which the population presents no immunity. Presently, there are few options for the control of influenza and annual immunization is the most effective means to prevent disease and its complications. In Brazil, according to data collected by the VigiGripe's Project - linked to the Federal University of Sao Paulo -, circulation of the influenza virus also has a seasonal pattern, with peak activity occurring between May and September. Yearly vaccination is, therefore, best indicated on March and April. Currently, there are four medications available for the treatment of influenza viruses: amantadine and rimantadine, and two second generation pharmaceutical products, the neuraminidase inhibitors, oseltamivir and zanamivir. The latter two drugs have set the stage for a new approach to the management and control of influenza infections.

Existem poucos instrumentos psicométricos em português aplicados em grupos bem definidos. Uma versão em português da bateria neuropsicológica CERAD foi aplicada a um grupo controle de 85 idosos saudáveis (GC) (média de idade 75,1/ média de educação 7,9), 31 indivíduos com doença de Alzheimer (DA) classificados pela Classificação Clínica para Demência (CDR) como CDR1 (71,4/ 9,0) e 12 indivíduos com DA CDR2 (74,1/ 9,3). Os pontos de corte foram: fluência verbal -- 11; teste de nomeação de Boston --12; MEEM -- 26; memória da lista de palavras -- 13; praxia construtiva -- 9; evocação de palavras -- 3; reconhecimento de palavras -- 7; evocação da praxia -- 4. Houve uma diferença significativa (p<0,0001) para todos os testes, exceto o de nomeação de Boston (p<0,368). A comparação entre AD-CDR1 e AD-CDR2 mostrou diferença apenas para o MEEM, fluência verbal e teste de nomeação de Boston. O desempenho do GC foi semelhante ao de uma população controle americana pareada para nível educacional. Estes resultados indicam que esta adaptação pode ser útil para o diagnóstico de demência inicial, mas estudos mais detalhados devem ser realizados para determinar os pontos de corte para pessoas analfabetas ou com baixa escolaridade.

There is a limited choice of psychometric tests for Portuguese speaking people which have been evaluated in well defined groups. A Portuguese version of CERAD neuropsychological battery was applied to a control group of healthy elderly (CG) (mean age 75.1 years/ education 7.9 years), 31 Alzheimer disease (AD) patients classified by clinical dementia rating (CDR) as CDR1 (71.4/ 9.0) and 12 AD patients CDR 2 (74.1/ 9.3). Cut-off points were: verbal fluency-11; modified Boston naming-12; Mini-mental State Examination (MMSE) -26; word list memory-13; constructional praxis-9; word recall-3, word recognition-7; praxis recall-4. There was a significant difference between CG and AD-CDR1 (p<0.0001) for all tests. There was a less significant difference for constructional praxis and no difference for Boston naming. Comparison between AD-CDR1 and AD-CDR2 showed difference only for MMSE, verbal fluency, and Boston naming. The performance of CG was similar to that of a US control sample with comparable education level. These results indicate that this adaptation may be useful for the diagnosis of mild dementia but further studies are needed to define cut-offs for illiterates/low education people.
