Um estudo de follow up em psicoterapia psicanalítica de casais

Por 11 anos desenvolvemos uma pesquisa envolvendo uma proposta interventiva com famílias que buscam atendimento em um serviço-escola, com demanda localizada na criança. Por meio da psicoterapia psicanalítica com o casal procuramos atingir a remissão dos sintomas do(s) filho(s). O objetivo deste estudo é refletir sobre a manutenção das mudanças psíquicas ocorridas nesse tipo de clínica, que abrange a esfera conjugal e familiar, ao longo do tempo. Com base na metodologia de estudo de caso e no referencial psicanalítico, foram analisados dois casos clínicos enfatizando-se as sessões de follow up: dois casais que estiveram em processo terapêutico, respectivamente, por três anos e por dois anos e meio, sendo realizadas duas sessões de acompanhamento após o término da terapia. Esse tipo de intervenção mostrou-se efetiva para a elucidação de conflitos conjugais latentes e como promovedora de um ambiente saudável e favorecedor do desenvolvimento emocional da criança.

Vírus respiratório sincicial humano em crianças hospitalizadas por infecções agudas das vias aéreas inferiores

OBJETIVO: Avaliar a prevalência e a sazonalidade do vírus respiratório sincicial humano (VRSH) em crianças de 0 a 6 anos hospitalizadas por infecção aguda das vias aéreas inferiores (IVAI) em São José do Rio Preto (SP) e a associação entre faixa etária, diagnóstico e VRSH. MÉTODOS: Entre maio de 2004 e setembro de 2005, foram estudados 290 episódios consecutivos de IVAI adquiridos na comunidade em crianças de 0 a 6 anos internadas no Hospital de Base de São José do Rio Preto. Para identificação do VRSH, foram coletadas amostras de secreção de nasofaringe e realizou-se análise molecular por meio da técnica de RT-PCR. RESULTADOS: A prevalência de VRSH foi de 29,3% nos episódios de IVAI hospitalizados. A IVAI foi frequente em lactentes (mediana de idade = 13,5 meses). O VRSH foi mais frequente nos casos de bronquiolite (64%) e no primeiro ano de vida (35%). Os episódios de infecção por VRSH ocorreram entre o outono e a primavera, com frequência maior em 2004 do que em 2005. Os critérios clínicos e radiológicos não foram suficientes para o diagnóstico de infecção pelo VRSH. Em 78,8% dos episódios de VRSH, houve tratamento com antibiótico. CONCLUSÕES: A prevalência do VRSH em crianças de 0 a 6 anos hospitalizadas por IVAI foi elevada, com predomínio nas mais jovens ou com bronquiolite. A circulação do vírus variou nos dois anos estudados. Os resultados sugerem necessidade de diagnóstico laboratorial do VRSR na prática clínica.

Avaliação do consumo alimentar e da ingestão de nutrientes na prática clínica

A avaliação do consumo alimentar na prática clínica é realizada com a finalidade de fornecer subsídios para o desenvolvimento e a implantação de planos nutricionais. Fatores como condições do estado geral do indivíduo/paciente, evolução da condição clínica e os motivos pelos quais o indivíduo necessita de orientação nutricional direcionam a escolha do método de avaliação do consumo alimentar. O método escolhido deve fornecer informações que permitam ao profissional orientar uma alimentação que vise promover a saúde, prevenir outras intercorrências e adequar o estado nutricional do paciente. Apesar de a literatura nacional disponibilizar informações abrangentes sobre métodos e técnicas para estimativa do consumo alimentar, o ambiente de atuação profissional ainda está permeado de dúvidas a respeito dos métodos mais adequados para essa avaliação na prática diária. O presente artigo se propôs a apresentar uma análise crítica, no contexto da aplicabilidade clínica, dos métodos disponíveis de inquéritos alimentares e suas características.

Tecnologias para investigação da DAC: relação entre publicações científicas e utilização clínica

FUNDAMENTO: Apesar de algumas evidências sugerirem associação entre a exposição de uma tecnologia na literatura científica e sua difusão na prática clínica, poucos estudos avaliaram essa associação. OBJETIVO: O objetivo deste estudo é analisar se o padrão de publicação científica sobre duas tecnologias competitivas utilizadas na avaliação da doença arterial coronária (DAC) reflete o que ocorre na prática clínica. MÉTODOS: Avaliou-se o número de artigos científicos publicados anualmente na literatura médica (interesse científico global na tecnologia) sobre duas tecnologias utilizadas na avaliação da doença arterial coronária: tomografia computadorizada por feixe de elétrons e tomografia computadorizada com múltiplos detectores. Foi também analisado o número de países que publicam anualmente artigos científicos sobre essas tecnologias (interesse geográfico na tecnologia). RESULTADOS: A tomografia computadorizada por feixe de elétrons (electron beam computed tomography - EBCT) apresentou ápice de "interesse científico global" em 2001, com 127 artigos publicados. Após esse ápice, o "interesse científico global" diminuiu cerca de 50% em 2008. Em oposição, o "interesse científico global" pela tomografia computadorizada com múltiplos detectores (multidetector computed tomography - MDCT) aumentou progressivamente até 2007, com 454 artigos publicados nesse ano. O "interesse científico geográfico" pela EBCT teve ápice em 2002, com 14 países publicando sobre essa tecnologia. Após esse ápice, "o interesse científico geográfico" declinou em quase 25% até 2008, com 11 países publicando artigos sobre essa tecnologia. Em oposição, o "interesse científico geográfico" pela MDCT aumentou progressivamente até 2008, com 37 países publicando artigos sobre ela. CONCLUSÃO: A literatura científica médica é compatível com a substituição da EBCT pela MDCT na avaliação da DAC.

Deficiência androgênica na mulher

As evidências sugerem que a deficiência androgênica na mulher exibe como principal manifestação clínica a disfunção sexual, especialmente a queda da libido. Entretanto, outros fatores podem também estar implicados na gênese da disfunção sexual, como o relacionamento interpessoal, os estressores sociais, o sedentarismo e o próprio fator masculino. A prevalência da disfunção sexual feminina oscila entre 9 por cento e 43 por cento e recentemente muitos estudos têm mostrado que a reposição com androgênios não só melhora o desempenho sexual, mas também os distúrbios do humor e sintomas vasomotores. Por isso, o profissional de saúde deve sempre incluir no diagnóstico diferencial da disfunção sexual a Síndrome de Deficiência Androgênica, mesmo em mulheres com concentrações séricas normais de estrogênios. O presente artigo tem como objetivo revisar os aspectos práticos da Síndrome de Deficiência Androgênica, enfocando especialmente o diagnóstico e tratamento. Para tanto, nos valemos da análise de 105 artigos publicados em revistas indexadas no PUBMED nos últimos 51 anos (até maio de 2010), incluindo consensos e opiniões de especialistas. Como conclusão, a Síndrome de Deficiência Androgênica na mulher é negligenciada, existindo ainda muitas controvérsias quanto ao seu diagnóstico e terapêutica, especialmente no tocante à escolha do androgênio, a via de administração e o tempo de duração de uso

Highlights from the I international symposium of thrombosis and anticoagulation in internal medicine, October 23–25, 2008, Sao Paulo, Brazil

Abstract The importance of thrombosis and anticoagulation in clinical practice is rooted firmly in several fundamental constructs that can be applied both broadly and globally. Awareness and the appropriate use of anticoagulant therapy remain the keys to prevention and treatment. However, to assure maximal efficacy and safety, the clinician must, according to the available evidence, choose the right drug, at the right dose, for the right patient, under the right indication, and for the right duration of time. The first International Symposium of Thrombosis and Anticoagulation in Internal Medicine was a scientific program developed by clinicians for clinicians. The primary objective of the meeting was to educate, motivate and inspire internists, cardiologists and hematologists by convening national and international visionaries, thought-leaders and dedicated clinician-scientists in Sao Paulo, Brazil. This article is a focused summary of the symposium proceedings

O Ginecologista obstetra e a internet

OBJETIVOS: identificar a influência do uso da internet na prática e ambiente de trabalho médico e verificar como estas mudanças vêm acorrendo entre médicos ginecologistas e obstetras. MÉTODO: foram enviados 1.120 questionários para médicos ginecologistas e obstetras da cidade de São Paulo, dos quais retornaram 152, o correspondente a 13,6 por cento da amostra ou 6,1 por cento do total dos médicos cadastrados na SOGESP. A análise quantitativa do comportamento do médico quanto ao uso da internet foi realizada por meio de proporções, médias, cálculos de desvios-padrão e do teste de associação de qui-quadrado. Através da técnica de Cluster Analysis, foram determinados 4 grupos segundo o perfil dos profissionais relacionado ao uso desta ferramenta. RESULTADOS: não se observou relação de idade, sexo, locais de trabalho e desenvolvimento de apenas uma das especialidades Ginecologia ou Obstetrícia quanto à utilização da internet na prática médica. Observou-se uma tendência de uso mais freqüente entre médicos com doutorado. Quanto aos serviços médicos prestados por e-mail, receber e devolver exames foram as atividades mais realizadas pelos sujeitos da pesquisa. CONCLUSÃO: os ginecologistas obstetras pesquisados utilizam a internet na prática médica para própria atualização, para comunicação com pacientes ou para oferecer serviços às mesmas com diferentes assiduidades. Entretanto, este uso é ainda parcial, talvez relacionado ao receio de interferências negativas na relação com o paciente, além de preocupações quanto à implicações legais, éticas e principalmente econômicas relacionadas à prática profissional

Time-resolved fluorescence spectroscopy of white-spot caries in human enamel

The objective is to differentiate noncavitated caries enamel through time-resolved fluorescence and to find excitation and emission parameters that can be applied in future clinical practice for detection of caries lesions that are not clearly visible to the professional. Sixteen human teeth with noncavitiated white-spot caries were selected for this work. Fluorescence intensity decay was measured by using an apparatus based on the time-correlated single-photon counting method. An optical fiber bundle was employed for sample excitation (440 nm), and the fluorescence collected by the same bundle (500 nm) was registered. The average lifetime for sound enamel was 7: 93 +/- 0: 09, 2: 46 +/- 0: 04, and 0: 51 +/- 0: 02 ns, whereas for the carious enamel the lifetimes were 4: 84 +/- 0: 06, 1: 35 +/- 0: 02, and 0: 16 +/- 0: 01 ns. It was concluded that it is possible to differentiate between carious and sound regions by time-resolved fluorescence and that, although the origin of enamel fluorescence is still uncertain, the lifetime values seem to be typical of fluorophores like collagen I.

ESPECTRA: Searching the Bipolar Spectrum in Eating Disorder patients

Background: Bipolar Disorder (BD) is a chronic, recurrent and highly prevalent illness. Despite the need for correct diagnosis to allow proper treatment, studies have shown that reaching a diagnosis can take up to ten years due to the lack of recognition of the broader presentations of BD. Frequent comorbidities with other psychiatric disorders are a major cause of misdiagnosis and warrant thorough evaluation. Methods/Design: ESPECTRA (Occurrence of Bipolar Spectrum Disorders in Eating Disorder Patients) is a single-site cross-sectional study involving a comparison group, designed to evaluate the prevalence of bipolar spectrum in an eating disorder sample. Women aged 18-45 years will be evaluated using the SCID-P and Zurich criteria for diagnosis and the HAM-D, YOUNG, SCI-MOODS, HCL-32, BIS-11, BSQ, WHOQoL and EAS instruments for rating symptoms and measuring clinical correlates. Discussion: The classificatory systems in psychiatry are based on categorical models that have been criticized for simplifying the diagnosis and leading to an increase in comorbidities. Some dimensional approaches have been proposed aimed at improving the validity and reliability of psychiatric disorder assessments, especially in conditions with high rates of comorbidity such as BD and Eating Disorder (ED). The Bipolar Spectrum (BS) remains under-recognized in clinical practice and its definition is not well established in current diagnostic guidelines. Broader evaluation of psychiatric disorders combining categorical and dimensional views could contribute to a more realistic understanding of comorbidities and help toward establishing a prognosis.

High-Dose Antipsychotic Medication; A Practical Pocket Checklist

There is evidence that a significant number of patients with schizophrenia and other chronic psychotic psychosis are prescribed high-dose antipsychotic drugs despite the fact that clinical guidelines recommend the routine use of a single antipsychotic drug in a standard dose. The prescriptions for high-dose and combined antipsychotic drugs are relatively common in clinical practice. This occurs despite the fact that results of published trials of high-dose antipsychotic drug treatment for schizophrenia provide little evidence to support effectiveness of using high-dose antipsychotic treatment and most importantly such strategy is not recommended. Moreover, there is mounting evidence of higher incidence of side effects and mortality associated with high dose antipsychotic treatment. Therefore we are presenting a practical pocket checklist which is aimed at minimizing predicted and unpredicted side effects during such treatments.

Severity of Oral Mucositis in Patients Undergoing Hematopoietic Cell Transplantation and an Oral Laser Phototherapy Protocol: A Survey of 30 Patients

Background Data and Objective: Oral mucositis (OM) is one of the worst cytotoxic effects of chemotherapy and radiotherapy in patients undergoing hematopoietic cell transplantation (HCT), and it causes severe morbidity. Laser phototherapy has been considered as an alternative therapy for prevention and treatment of OM. The aim of this study was to describe the incidence and severity of OM in HCT patients subjected to laser phototherapy, and to discuss its effect on the oral mucosa. Patients and Methods: Information concerning patient age and gender, type of basic disease, conditioning regimen, type of transplant, absence or presence of pain related to the oral cavity, OM grade, and adverse reactions or unusual events were collected from 30 patients undergoing HCT (allogeneic or autologous). These patients were given oral laser phototherapy with a InGaAIP laser (660 nm and 40 mW) daily. The data were tabulated and their frequency expressed as percentages. Results: In the analysis of those with OM, it was observed that 33.4% exhibited grade I, 40% grade II, 23.3% grade III, and 3.3% grade IV disease. On the most critical post-HCT days (D+5 and D+8), it was observed that 63.3% of patients had grade I and 33.3% had grade II disease; no patients had grade III or IV disease in this period. This severity of OM was similar to that seen in other studies of laser phototherapy and OM. Conclusion: The low grades of OM observed in this survey show the beneficial effects of laser phototherapy, but randomized clinical trials are necessary to confirm these findings.

Investigation of mast cells in human gingiva following low-intensity laser irradiation

Objective: The aims of the present study were to investigate the effect of low-intensity laser irradiation on the total number of mast cells as well as the percentage of degranulation in human gingiva. Blood vessel dilation was also evaluated. Background Data: It has been proposed that low-intensity laser irradiation can ameliorate pain, swelling, and inflammation. In periodontal tissue, mast cells may influence either the destructive events or the defense mechanism against periodontal disease via secretion of cytokines and through cellular migration to improve the healing process. Mast cells play an important role in the inflammatory process. Methods: Twenty patients with gingival enlargement indicated for gingivectomy were selected. Gingival fragments were obtained from each patient and divided into three different groups before surgery. One fragment was removed without any irradiation. The two others were submitted to punctual irradiation with an energy density of 8 J/cm(2) at an output power of 50 mW at 36 Hz for 36 sec before gingivectomy. Nondegranulated and degranulated mast cells were counted in five areas of the gingival fragment connective tissue. Major and minor diameters of the blood vessels were also measured. Results: Both red and infrared radiation promoted a significant increase in mast cell degranulation compared to controls; however, no statistically significant differences (p > 0.05) were observed between the irradiated groups. No significant differences among the groups were observed regarding blood vessel size. Conclusion: The results suggests that red and infrared wavelengths promote mast cell degranulation in human gingival tissue, although no dilation of blood vessels was observed. The effects of premature degranulation of mast cells in human tissue and the laser radiation protocol applied in this study encourage further investigations to extend these results into clinical practice.

Viability of fibroblasts cultured under nutritional stress irradiated with red laser, infrared laser, and red light-emitting diode

Phototherapy is noninvasive, painless and has no known side effect. However, for its incorporation into clinical practice, more well-designed studies are necessary to define optimal parameters for its application. The viability of fibroblasts cultured under nutritional stress irradiated with either a red laser, an infrared laser, or a red light-emitting diode (LED) was analyzed. Irradiation parameters were: red laser (660 nm, 40 mW, 1 W/cm(2)), infrared laser (780 nm, 40 mW, 1 W/cm(2)), and red LED (637 +/- 15 nm, 40 mW, 1 W/cm(2)). All applications were punctual and performed with a spot with 0.4 mm(2) of diameter for 4 or 8 s. The Kruskal-Wallis test and analysis of variance of the general linear model (p <= 0.05) were used for statistical analysis. After 72 h, phototherapy with low-intensity laser and LED showed no toxicity at the cellular level. It even stimulated methylthiazol tetrazolium assay (MTT) conversion and neutral red uptake of fibroblasts cultured under nutritional stress, especially in the group irradiated with infrared laser (p = 0.004 for MTT conversion and p < 0.001 for neutral red uptake). Considering the parameters and protocol of phototherapy used, it can be concluded that phototherapy stimulated the viability of fibroblasts cultured under nutritional deficit resembling those found in traumatized tissue in which cell viability is reduced.

Analysis of pelvic floor musculature function during pregnancy and postpartum: a cohort study

Aim. To compare the measurements of women`s pelvic floor musculature strength (PFMS) during pregnancy and postpartum period. Background. Pregnancy and childbirth can have an influence on the muscles and pelvic floor and can cause morbidities of women`s genito-urinary tract. Design. A prospective cohort study. Methods. There were included 226 primigravidae women, attended by community health services in the city of Itapecerica da Serra, Sao Paulo, Brazil. The participants were followed in four stages: (1) within 12 weeks of pregnancy; (2) between 36-40 weeks of pregnancy; (3) within 48 hours after childbirth; (4) 42-60 days after childbirth. Data were collected from February 2007-August 2008. The pelvic floor musculature strength was evaluated by perineometry and digital vaginal palpation in stages 1, 2 and 4. The final sample included 110 women who completed all four stages of the study. Results. The pelvic floor musculature strength of the women did not change significantly during pregnancy or after delivery (anova: p = 0 center dot 78). In all three examined stages, a low-intensity pelvic floor musculature strength was prevalent (in mmHg: stage 1 = 15 center dot 9; stage 2 = 15 center dot 2, stage 4 = 14 center dot 7), with scores from 0-3 on the Oxford scale. The pelvic floor musculature strength did not differ in relation to maternal age, skin colour, conjugal status, dyspareunia, stool characteristics, type of delivery, or conditions of the perineum. An interaction between maternal nutritional state and newborn`s weight may affect the pelvic floor musculature strength (manova: p = 0 center dot 04). Conclusion. Pregnancy and childbirth did not reduce significantly pelvic floor musculature strength. The perineometry and digital vaginal palpation used to assess the pelvic floor musculature strength were well accepted by the women. Relevance to clinical practice. In clinical practice, digital vaginal palpation is effective for supporting the diagnosis of urinary, intestinal and sexual dysfunctions. Perineometry use is particularly important together with the performance of perineal exercises with biofeedback in the treatment these disorders.

Pressure Ulcer Knowledge Among Nurses in a Brazilian University Hospital

To facilitate the implementation of evidence-based skin and pressure ulcer (PU) care practices and related staff education programs in a university hospital in Brazil, a cross-sectional study was conducted to evaluate nurses` knowledge about PU prevention, wound assessment, and staging. Of the 141 baccalaureate nurses (BSN) employed by the hospital at the time of the study, 106 consented to participate. Using a Portuguese version of Pieper`s Pressure Ulcer Knowledge Test (PUKT), participants were asked to indicate whether 33 statements about PU prevention and eight about PU assessment and staging were true or false. For the 33 prevention statements, the average number answered correctly was 26.07 (SD 4.93) and for the eight assessment statements the average was 4.59 (SD 1.62). Nurses working on inpatient clinical nursing units had significantly better scores (P = 0.000). Years of nursing experience had a weak and negative correlation with correct PUKT scores (r = -0.21, P = 0.033) as did years of experience working in the university hospital (r = -.179, P <071). Incorrect responses were most common for statements related to patient positioning, massage, PU assessment, and staging definitions. The results of this study confirm that nurses have an overall understanding of PU prevention and assessment principles but important knowledge deficits exist. Focused continuing education efforts are needed to facilitate the implementation of evidence-based care.
