Sexual dysfunction and dissatisfaction in chronic hepatitis C patients

IntroductionThe prevalence of sexual dysfunction (SD) and dissatisfaction with sexual life (DSL) in patients with chronic hepatitis C virus infection (CHC) was jointly investigated via a thorough psychopathological analysis, which included dimensions such as fatigue, impulsiveness, psychiatric comorbidity, health-related quality of life (HRQL) and sociodemographic and clinical characteristics.MethodsMale and female CHC patients from an outpatient referral center were assessed using the Brief Fatigue Inventory, the Barrat Impulsiveness Scale, the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale (HAM-A), and the World Health Organization Quality of Life Scale-Brief Version (WHOQOL-BREF). Structured psychiatric interviews were performed according to the Mini-International Neuropsychiatric Interview. SD was assessed based on specific items in the BDI (item 21) and the HAM-A (item 12). DSL was assessed based on a specific question in the WHOQOL-BREF (item 21). Multivariate analysis was performed according to an ordinal linear regression model in which SD and DSL were considered as outcome variables.ResultsSD was reported by 60 (57.1%) of the patients according to the results of the BDI and by 54 (51.4%) of the patients according to the results of the HAM-A. SD was associated with older age, female gender, viral genotype 2 or 3, interferon-α use, impulsiveness, depressive symptoms, antidepressant and benzodiazepine use, and lower HRQL. DSL was reported by 34 (32.4%) of the patients and was associated with depressive symptoms, anxiety symptoms, antidepressant use, and lower HRQL.ConclusionsThe prevalence of SD and DSL in CHC patients was high and was associated with factors, such as depressive symptoms and antidepressant use. Screening and managing these conditions represent significant steps toward improving medical assistance and the HRQL of CHC patients.

Evaluation of constitutive and inducible resistance to clindamycin in clinical samples of Staphylococcus aureus from a tertiary hospital

IntroductionInfections caused by methicillin-resistant Staphylococcus aureus (MRSA) have become common in hospitals and the community environment, and this wide resistance has limited patient treatment. Clindamycin (CL) represents an important alternative therapy for infections caused by S. aureus. Antimicrobial susceptibility testing using standard methods may not detect inducible CL resistance. This study was performed to detect the phenotypes of resistance to macrolides-lincosamides-streptogramin B (MLSB) antibiotics, including CL, in clinical samples of S. aureusfrom patients at a tertiary hospital in Santa Maria, State of Rio Grande do Sul, Brazil.MethodsOne hundred and forty clinical isolates were submitted to the disk diffusion induction test (D-test) with an erythromycin (ER) disk positioned at a distance of 20mm from a CL disk. The results were interpreted according to the recommendations of the Clinical and Laboratory Standards Institute (CLSI).ResultsIn this study, 29 (20.7%) of the 140 S. aureus samples were resistant to methicillin (MRSA), and 111 (79.3%) were susceptible to methicillin (MSSA). The constitutive resistance phenotype (cMLSB) was observed in 20 (14.3%) MRSA samples and in 5 (3.6%) MSSA samples, whereas the inducible resistance phenotype (iMLSB) was observed in 3 (2.1%) MRSA samples and in 8 (5.8%) MSSA samples.ConclusionsThe D-test is essential for detecting the iMLSBphenotype because the early identification of this phenotype allows clinicians to choose an appropriate treatment for patients. Furthermore, this test is simple, easy to perform and inexpensive.

Mental health and neuroscience. A perspective from the magazine market

Mental health awareness has been rising worldwide, motivated by its social and economic costs. Despite the investment in research in neuroscience in the recent years, little is known about the underlying mechanisms in the brain that are correlated with psychiatric conditions. This project, through two feature articles suitable to be published in magazines, provides perspectives onto mental health research. First it presents an example where psychiatry joins forces with neuroscience and computer science in an interdisciplinary effort to improve the life of those affected by mental disorders. The second article gathers opinions which claim that mental health research priorities should be set by patients themselves, or even that people with lived experience of mental health issues should have an active role in that research. This project was planned and researched while I was an Erasmus student at Nottingham Trent University, in the United Kingdom.

Clinical conditions associated withintestinal strongyloidiasis in Rio de Janeiro, Brazil

INTRODUCTION: Strongyloides stercoralis is a soil-transmitted helminth that produces an infection that can persist for decades. The relationships between certain clinical conditions and strongyloidiasis remains controversial. This study aims to identify the clinical conditions associated with intestinal strongyloidiasis at a reference center for infectious diseases in Rio de Janeiro, Brazil. METHODS: The clinical conditions that were assessed included HIV/AIDS, HTLV infection, cardiovascular diseases, diabetes, obstructive respiratory diseases, viral hepatitis, tuberculosis, cancer, chronic renal disease, nutritional/metabolic disorders, psychiatric conditions, rheumatic diseases and dermatologic diseases. We compared 167 S. stercoralis-positive and 133 S. stercoralis-negative patients. RESULTS: After controlling for sex (male/female OR = 2.29; 95% (CI): (1.42 - 3.70), rheumatic diseases remained significantly associated with intestinal strongyloidiasis (OR: 4.96; 95% CI: 1.34-18.37) in a multiple logistic regression model. With respect to leukocyte counts, patients with strongyloidiasis presented with significantly higher relative eosinophil (10.32% ± 7.2 vs. 4.23% ± 2.92) and monocyte (8.49% ± 7.25 vs. 5.39% ± 4.31) counts and lower segmented neutrophil (52.85% ± 15.31 vs. 61.32% ± 11.4) and lymphocyte counts (28.11% ± 9.72 vs. 30.90% ± 9.51) than S. stercoralis-negative patients. CONCLUSIONS: Strongyloidiasis should be routinely investigated in hospitalized patients with complex conditions facilitate the treatment of patients who will undergo immunosuppressive therapy. Diagnoses should be determined through the use of appropriate parasitological methods, such as the Baermann-Moraes technique.

Implementation progress of mental health services in Rwanda: Bugesera district case

RESUMO: O Ministério da Saúde do Governo do Ruanda identifica a saúde mental como uma área de prioridade estratégica para a intervenção em resposta à alta carga dos transtornos mentais no Ruanda. Ao longo dos últimos 20 anos após o genocídio, o sector público reconstruiu sua Resposta Nacional de Saúde Mental com base no acesso equitativo aos cuidados, através do desenvolvimento de uma Política Nacional de Saúde Mental e novas estruturas de saúde mental. A política de Saúde Mental do Ruanda, revista em 2010, prima pela descentralização e integração dos serviços de saúde mental em todas as estruturas nacionais do sistema de saúde e ao nível da comunidade. O presente estudo de caso tem como objetivo avaliar a situação do sistema de saúde mental de um distrito típico de uma área rural no Ruanda, e sugerir melhorias, incluindo algumas estratégias para monitoras as mudanças. Os resultados do estudo permitirão ao Ruanda reforçar a sua capacidade para implementar o Plano Nacional de Saúde Mental ao nível dos distritos. O relatório também será útil para monitorar o progresso da implementação de serviços de saúde mental nos distritos, incluindo a prestação de serviços de base comunitária e a participação dos usuários, suas famílias e outros interessados na promoção, prevenção, assistência e reabilitação em saúde mental. Este estudo também procurou avaliar o progresso da implementação dos cuidados de saúde mental a nível descentralizado, com vista a compreender as implicações em termos de recursos desses processos. Foi realizada uma análise situacional num local do distrito, baseado em entrevistas com as principais partes interessadas responsáveis, usando o Instrumento de Avaliação de Sistemas de Saúde Mental da Organização Mundial da Saúde (WHO-AIMS). Os resultados sugerem que os recursos humanos para a saúde mental e serviços de base comunitária de saúde mental no distrito continuam a ser extremamente limitados. Os profissionais de saúde mental são adicionalmente limitados na sua capacidade para oferecer intervenções de emergência a pacientes psiquiátricos e garantir a continuidade do tratamento farmacológico a pacientes com condições crônicas. Para planejar efetivamente, de acordo com as necessidades da comunidade, sugerimos que o sistema de saúde mental deve envolver também os representantes das famílias e dos usuários no processo de planificação de modo a melhorar a sua contribuição no processo de implementação das atividades de saúde mental. Este estudo de caso do Distrito de Bugesera oferece a primeira análise de nível distrital dos serviços de saúde mental no Ruanda, e pode servir como uma mais-valia para a melhoria do sistema de saúde mental, incluindo a advocacia para a melhoria da qualidade dos cuidados de saúde mental a este nível, aumentando o financiamento para a implementação de serviços clínicos de saúde mental e os recursos humanos disponíveis para a prestação de cuidados de saúde mental, principalmente a nível dos cuidados primários.--------------------- ABSTRACT: To deal with the high burden of mental health disorders resulting from consequences of the 1994 genocide against Tutsis, the Rwanda Ministry of Health (MoH) considers mental health as a priority intervention. For the last 20 years, Ministry of Health focused on rebuilding a national and equity-oriented mental health program responding to the population needs in mental health. Mental health services are now decentralized and integrated in the national health system, from the community level up to the referral level. This study assessed the situation of mental health services in one rural district in Rwanda. It was aimed at assessing the progress of implementation of mental health care at the decentralized level, focusing on resource implications and processes. This study is based on interviews conducted with key stakeholders, using the World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS). Findings show that human resources for mental health care and community-based mental health services of the assessed district remain extremely limited. Mental health professionals face limitation regarding the ability to provide emergency management of psychiatric patients and to ensure continuity of psychopharmacological treatment of patients with chronic conditions. To improve the implementation process of mental health interventions and activities, a planning process based on community needs and the involvement of representatives of families and users in planning process should be considered. The Bugesera case study on the situation of mental health services can serve as a baseline for improvement of the mental health program in Rwanda, in terms of quality care services, infrastructure and equipment, human and financial resources.

Perfil imunológico de grávidas atópicas versus grávidas saudáveis

RESUMO: A prevalência das doenças atópicas tem vindo a aumentar, em especial ao nível dos países ocidentalizados. Vários fatores têm sido apontados para justificar este aumento de prevalência,destacando-se o reduzido tamanho das famílias, o elevado uso de antibióticos, a melhoria das condições sanitárias, bem como a diminuição quer das infeções de helmintas, quer da contaminação orofecal. Alguns estudos têm também avaliado a influência do ambiente pré-natal no desenvolvimento de atopia e asma. Da análise da literatura, parece inegável a importância deste período para o desenvolvimento do sistema imunitário. Neste âmbito, a transmissão de atopia à descendência em mulheres atópicas, e concretamente com asma alérgica, poderá ser moldada desde este período. A possibilidade de identificar marcadores de risco precoces para o desenvolvimento de atopia poderá ser o primeiro passo para o desenvolvimento de estratégias de prevenção para os indivíduos em risco. Este trabalho pretendeu abordar o sistema imunitário materno de forma a enriquecer a sua caraterização desde o terceiro trimestre da gravidez até ao fim do puerpério. Para além da exploração de perfis celulares e citocínicos maternos (nos quais se incluiu sobretudo a avaliação de diferentes populações de células T e B, com funções efetoras e reguladoras), foi também considerada a sua eventual relação com o desenvolvimento de atopia nas crianças. Foram recrutadas 135 mulheres com critérios para serem incluídas num dos 4 grupos do estudo: grávidas atópicas – GA (n=24), não grávidas atópicas – NGA (n=32), grávidas saudáveis – GS (n=44) e não grávidas saudáveis – NGS (n=35). Foram caraterizadas por Citometria de Fluxo populações de leucócitos e linfócitos, com particular interesse nos perfis maturativos de linfócitos T e B, bem como nas subpopulações de células T e B reguladoras. Foi ainda efetuada uma análise funcional, para avaliar a capacidade de produção de citocinas pelos linfócitos T e B. Foram igualmente avaliadas as concentrações de citocinas séricas por ensaios imunoenzimáticos. Estes parâmetros imunológicos maternos foram acompanhados desde o terceiro trimestre de gestação, até depois do puerpério (primeiras 6 semanas pós parto), e aos seis meses de idade, foi efetuada uma avaliação clínica das crianças. As mulheres não grávidas atópicas apresentaram contagens celulares mais elevadas para a generalidade das populações leucocitárias e linfocitárias (em relação a mulheres não grávidas saudáveis). Destaca-se ainda uma maior presença de eosinófilos nas mulheres NGA (p=0,0009; teste de Mann-Whitney U), que tinham igualmente os seus compartimentos linfocitários T e B mais ricos em células de memória, em relação às mulheres NGS. Para os perfis de regulação, verificou-se que as células T reguladoras se encontravam percentualmente aumentadas (p≤0,003; teste de Mann-Whitney U), tal omo as células T produtoras de IL10 após estimulação (p≤0,03; teste de Mann-Whitney U) em mulheres NGA. Também se observou uma maior expressão de Foxp3 (p=0,0002; teste de Mann-Whitney U), e ainda a diminuição dos níveis séricos de IFN-γ nas mulheres NGA (p=0,0019; teste de Mann-Whitney U), em relação a mulheres NGS. De um modo geral, as alterações verificadas nos parâmetros imunológicos de mulheres grávidas atópicas no terceiro trimestre da gravidez foram semelhantes às observadas em mulheres grávidas saudáveis. Comparadas com mulheres NGA, nas mulheres grávidas atópicas ocorreu uma alteração substancial da fórmula leucocitária, com um importante incremento de neutrófilos (p<0,0001; teste de Mann-Whitney U) e diminuição dos valores das restantes populações leucocitárias. A diminuição nas contagens de linfócitos totais estendeu-se a grande parte das subpopulações linfocitárias caraterizadas. Nos compartimentos linfocitários T e B foi possível observar uma diminuição das subpopulações de células de memória. Verificou-se igualmente na gravidez uma menor expressão de Foxp3 em mulheres GA (p<0,0001; teste de Mann-Whitney U) e ainda menos células B CD24HiCD38Hi circulantes (p=0,0012; teste de Mann-Whitney U). Ocrreu ainda uma diminuição relativa das células T CD4 produtoras de IFN-γ em mulheres GA (p≤0,024; teste de Mann-Whitney U), e uma maior presença de células T CD8 produtoras de IL17 (p=0,0172; teste de Mann-Whitney U), em relação ao observado em mulheres NGA. Depois do puerpério, no compartimento T de mulheres do grupo GA, verificou-se um aumento das populações de células de memória. Em comparação com a gravidez, após o puerpério o compartimento B, apresentou nas mulheres GA um aumento significativo da subpopulação de células B de transição (p<0,0001; teste de Wilcoxon). Verificou-se, igualmente em mulheres GA após o puerpério, uma maior expressão de Foxp3 nas células T reguladoras (p<0,0001; teste de Wilcoxon) e o aumento das populações de células T circulantes produtoras de IFN-γ (p≤0,0234; teste de Wilcoxon). As modulações das populações T e B desde a gravidez até depois do puerpério ocorreram de forma semelhante nas mulheres dos grupos GA e GS. Apesar de as mulheres GA manterem um perfil imunológico próximo do das mulheres GS depois do puerpério, aconteceu também neste período um processo de reaproximação ao perfil observado nas mulheres NGA. As mulheres GA com manifestações de risco para atopia na descendência (comparadas com mulheres GA sem manifestações de risco para atopia na descendência até aos 6 meses de vida) apresentaram uma maior proporção de células T e menor proporção de células B, percentagens mais elevadas de células T CD8 de memória efetoras, de células B de transição e de células B CD24HiCD38Hi, e contagens mais baixas de células B de memória. Na avaliação destes parâmetros como marcadores de risco para o desenvolvimento de atopia verificou-se que o parâmetro com melhor desempenho foi a percentagem de células B de transição, com uma Odds-Ratio de 54,0 [IC 95%: 4,2-692,9; (p=0,0005)], sensibilidade de 90,0% [IC 95%: 55,5 – 99,8] e especificidade de 85,7% [IC 95%: 57,2 – 98,2]. Este estudo foi pioneiro em Portugal, e no mundo, no que se refere ao acompanhamento do compartimento linfocitário B circulante, abordando o seu perfil de maturação, e em particular as células B com funções reguladoras, desde a gravidez até ao fim do puerpério, em mulheres atópicas e não atópicas. A este nível, encontram-se estudos na literatura a documentar a alteração do compartimento B durante a gravidez. O presente trabalho reporta agora que alterações, como a diminuição do número de células B em circulação, são impostas também na mulher atópica. Em suma, demonstrou-se a existência de um perfil imunológico caraterístico em mulheres atópicas, que sofre alterações significativas durante a gravidez, tendendo os parâmetros imunológicos a normalizar após o puerpério. O compartimento T, para o qual a literatura é mais rica em estudos e abordagens, demonstrou também neste trabalho oscilações caraterísticas entre o período pré e pós-natal. Verificaram-se sobretudo variações nos compartimentos de células T de memória, sem grandes alterações ao nível das células Treg no que se refere à sua presença em circulação. Apenas a registar a menor expressão de Foxp3 nas células Treg durante a gestação observada em mulheres atópicas, tal como em mulheres saudáveis (como também já foi relatado em estudos anteriores). Apesar de muitos dos dados se encontrarem em concordância com a literatura, quer no que se refere às subpopulações de células de memória, quer no que se refere às células Treg, também se encontram resultados discordantes, por exemplo documentando variações numéricas nas células Treg em circulação em mulheres atópicas e mulheres atópicas grávidas. A importância de harmonizar protocolos e fenótipos, parece crucial na abordagem de estudos futuros. Ao nível do risco para a atopia na descendência de mulheres atópicas, acrescentou-se ainda a possibilidade de definir marcadores não invasivos para a criança, em particular as células B de transição. Estas células, cuja maior presença em circulação no recém-nascido foi recentemente associada com manifestações alérgicas subsequentes, são agora apontadas já na mulher atópica, grávida do terceiro trimestre, como um elemento de risco para o desenvolvimento de atopia. Os marcadores de risco descritos, para além de facilmente poderem vir a ser englobados no âmbito dos normais rastreios maternos durante a gravidez, apresentam ainda a vantagem da precocidade do diagnóstico, permitindo não só a possibilidade de prevenção pós-natal, mas estendendo esta possibilidade ao período gestacional.----------------------------ABSTRACT: The prevalence of atopic diseases has been increasing, especially in Westernized countries. Several factors have been suggested to justify this increase in prevalence, as the small size of families, the high use of antibiotics, the improvement in sanitation conditions, as well as the reduction of both helminth infections, and orofecal contamination. A few studies have adressed the influence of prenatal environment on the development of atopy and asthma. From literature, it seems undeniable the importance of the prenatal period for the development of the immune system. In this context, the transmission of atopy to the progeny in atopic women, and specifically in women with allergic asthma, can be modulated from this period on. The ability to detect early risk markers for the development of atopic diseases may be the first step in the development of prevention strategies for individuals at risk. This study aimed to approach the maternal immune system in order to enrich its characterization from the third trimester of pregnancy until the end of the puerperium period. In addition to the evaluation of the maternal cellular profiles (in which, mostly, diferente populations of T and B cells with effector and regulatory functions were included) and citokines, the relation between these profiles and the development of atopy in the progeny was also assessed. 135 women were recruited for this study, and fullfiled the inclusion criteria necessary to be included in one of the four groups preset: atopic pregnant women - GA (n = 24), atopic nonpregnant women - NGA (n = 32), healthy pregnant women - GS (n = 44) and healthy nonpregnant women - NGS (n = 35). Populations of leukocytes and lymphocytes, and particularty maturation profiles of T and B lymphocytes, as well as subpopulations of T and B cells with regulatory functions, were characterized by flow cytometry. Functional assays were also performed, to assess the ability of cytokine production by T and B lymphocytes. Serum cytokine concentrations were assessed as well by enzymatic immunoassays. These maternal imune parameters were monitored since the third trimester of pregnancy until the end of the puerperium period (first six weeks after delivery). A clinical evaluation of all the newborn children was performed at the age of six months. Non-atopic pregnant women presented higher cell counts for most leukocyte and lymphocyte populations (compared to healthy non-pregnant women). We should also highlight the increased presence of eosinophils in NGA women (p = 0,0009; Mann-Whitney U test). Again compared to NGS women, NGA women showed increased memory cells within the circulating T and B lymphocyte compartments. Considering the regulatory profiles, NGA women presented higher percentages of regulatory T cells (p≤0,003; Mann-Whitney U test) and IL10 producing T cells after stimulation (p≤0,03; Mann Whitney U), as well as increased expression of Foxp3 (p = 0,0002; Mann-Whitney U test), and also decreased serum levels of IFN-γ (p = 0,0019; test Mann-Whitney U test) compared to NGS women. In general, the changes observed in immune parameters of atopic pregnant women in the third trimester of gestation were similar to those observed in healthy pregnant women. Comparing pregnant and non-pregnant atopic women, an important change in leukocyte subsets was observed, with a significant increase of neutrophils (p <0,0001; Mann-Whitney U test) and the consequent diminution of the remaining leukocyte populations in the GA group. The decrease in total lymphocyte counts was extended to most of the lymphocyte subsets characterized. It was possible to detect a decrease in memory cell subsets within the T and B lymphocyte compartments, also. During pregnancy, a lower expression of Foxp3 was reported in GA women (p <0,0001; Mann-Whitney U test) and, besides, lesser CD24HiCD38Hi B cells were present in circulation in these women, compared to NGA women (p = 0,0012; Mann-Whitney U test). There was still a decrease in the percentages of IFN-γ-producing CD4 T cells in GA women (p≤0,024; Mann-Whitney U test) and a greater presence of IL17-producing CD8 T cells (p = 0,0172; Mann-Whitney U test), compared to the levels observed in NGA women. At the end of the puerperium, there was an increase in memory cell subpopulations within the T cell compartment of GA women. Compared with the pregnancy evaluation, after puerperium, the B cell compartment showed a significant increase in the transitional subpopulation (p<0,0001; Wilcoxon test), in GA women. Moreover, after puerperium, GA women exhibited a greater expression of Foxp3 in Treg cells (p <0,0001; Wilcoxon test) and there was an increase in circulating IFN-γ-producing T cells (p≤0,0234; Test Wilcoxon). The modulations of T and B cell subpopulations from pregnancy until the end of puerperium were similar in women of GA and GS groups. Although at the end of puerperium, GA women still kept an immune profile close the one observed in GS women, at this time point, there were also signs of rapprochement between the immune profiles observed in women of GA and NGA groups. GA women with atopic manifestations in the offspring (compared to GA women without atopic manifestations in the offspring at the age of 6 months) presented higher proportions of T cells and lower proportions of B cells, higher percentages of effector memory CD8 T cells, transitional B cells and CD24HiCD38Hi B cells, and, finally, lower absolute counts of memory B cells. In the evaluation of these parameters as risk markers for the development of atopy, the parameter which presented the best performance was the percentage of transitional B cells, with an Oddsratio of 54,0 [95% CI: 4,2 to 692,9; (p = 0,0005)], sensitivity of 90,0% [95% CI: 55,5 to 99,8] and a specificity of 85,7% [95% CI: 57,2 to 98,2]. This study was a pioneer in Portugal, and in the world, in what concerns the monitoring of the circulating B cell compartment, addressing not only the maturation profile, but, in particular, B cells with regulatory functions, from pregnancy untill after puerperium, in atopic and non-atopic women. Literature presents evidence of a typical change in circulating B cells during pregnancy. This study now reports that changes, such as the decrease in the number of circulating B cells,/ are also imposed by pregnancy in atopic woman. In brief, it demonstrated the existence of a characteristic immune profile in atopic women, which undergoes significant alterations during pregnancy, tending to normalize after the puerperium. As for the T cell compartment, for which the literature is richer in studies and approaches, this study also showed characteristic fluctuations between the pre- and postnatal periods. There were variations mostly in the memory subsets within the T cell compartment, without major changes in regulatory T cells regarding their presence in circulation. Only the expression of Foxp3 in Treg cells presented lower levels during pregnancy, in both atopic and healthy women (as previously reported in other studies). Although much of the data now reported are in agreement with literature, regarding either memory cell subsets or regulatory T cells, there are also conflicting results, for example documenting changes in the numbers of regulatory T cells circulating in atopic pregnant and atopic non-pregnant women. The importance of harmonizing protocols and phenotypes seems crucial for the establishement of future studies. Considering the risk for atopy in the offspring of atopic women, this study added the possibility to define non-invasive markers for the child, in particular transitional B cells. These cells, whose greater presence in circulation in newborns has recently been associated with subsequent allergy development, are here identified in atopic pregnant women in the third trimester of gestation as a risk factor in the development of atopy in their progeny. The risk factors described, besides having the capacity to easily become integrated within the normal maternal screening protocols during pregnancy, also have the advantage of an early diagnosis, allowing not only the possibility of postnatal prevention but extending this possibility to the prenatal period.

Indicators of inflammation and cellular damage in chronic asymptomatic or oligosymptomatic alcoholics: correlation with alteration of bilirubin and hepatic and pancreatic enzymes

Biochemical and hematimetric indicators of inflammation and cell damage were correlated with bilirubin and hepatic and pancreatic enzymes in 30 chronic male alcoholics admitted into psychiatric hospital for detoxification and treatment of alcoholism. Aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, and total bilirubin were altered, respectively, in 90%, 63%, 87%, 23% and 23% of the cases. None of the indicators of inflammation (lactic dehydrogenase, altered in 16% of the cases; alpha-1 globulin, 24%; alpha-2 globulin, 88%; leucocyte counts, 28%) was correlated with alterations of bilirubin or liver enzymes. Lactic dehydrogenase was poorly sensitive for detection of hepatocytic or muscular damage. Alterations of alpha-globulins seemed to have been due more to alcohol metabolism-induced increase of lipoproteins than to inflammation. Among indicators of cell damage, serum iron, increased in 40% of the cases, seemed to be related to liver damage while creatine phosphokinase, increased in 84% of the cases, related to muscle damage. Hyperamylasemia was found in 20% of the cases and significantly correlated with levels of bilirubin, alkaline phosphatase and gamma-glutamyltransferase. It was indicated that injuries of liver, pancreas, salivary glands, and muscle occurred in asymptomatic or oligosymptomatic chronic alcoholics.

Liver synthesis function in chronic asymptomatic or oligosymptomatic alcoholics: correlation with other liver tests

Liver function and its correlation with bilirubin and hepatic enzymes were evaluated in 30 male chronic asymptomatic or oligosymptomatic alcoholics admitted into the psychiatric hospital for detoxification and treatment of alcoholism. Hypoalbuminemia, lowered prothrombin activity, hypotransferrinemia and hypofibrinogenemia were detected in 32 %, 32 %, 28 %, and 24 % of patients, respectively. Transferrin was elevated in 8 %. Greater prevalence of hyperbilirubinemia was found in patients with lowered prothrombin activity, hypofibrinogenemia, or hypotransferrinemia. No correlation was found between serum bilirubin or aminotransferase levels and normal or elevated albumin levels, time or activity of prothrombin, and fibrinogen levels. Serum alkaline phosphatase was elevated in normoalbuminemics and gamma-glutamyltransferase in patients with lowered prothrombin activity. Hypoalbuminemia was associated with hypofibrinogenemia, hypotransferrinemia with elevated aspartate aminotransferase or gamma-glutamyltransferase, and hypertransferrinemia with elevation of alanine aminotransferase. These data indicated the occurrence of hepatic dysfunction due to liver damage caused directly by alcohol or by alcoholism-associated nutritional deficiencies.

Depression and dementia of cerebrovascular origin

We report the case of a patient who presented various psychiatric syndromes at the time of evaluation - partial complex epileptic seizures, personality change, and severe depression, which eventually progressed to dementia - resulting from multiple cerebral infarctions of probable neuro-angiopathic origin, of unknown etiology. Aspects related to depression following cerebrovascular accidents, as well as how cerebrovascular accidents can result in different disorders depending on the variables, are discussed based on the data from current literature.

Electroconvulsive therapy in treatment-resistant mania: case reports

Electroconvulsive therapy is known to be effective in the treatment of mood disorders, more specifically for depression and mania. Although a large body of evidence confirms the efficacy of electroconvulsive therapy in the treatment of mania, few prospective studies have been done to assess its effectiveness in treatment-resistant manic episodes. These case reports describe the initial results of a study that is being conducted to evaluate the efficacy of Electroconvulsive therapy among treatment-resistant bipolar patients. METHODS: Three manic patients (according to DSM-IV criteria) who were considered treatment-resistant underwent a series of 12 bilateral Electroconvulsive therapy sessions. Before the treatment and then weekly, they were evaluated with the following rating scales: Young Mania Rating Scale, Hamilton Rating Scale for Depression, Brief Psychiatric Rating Scale, and Clinical Global Impressions-Bipolar Version. RESULTS: The 3 patients showed a satisfactory response to Electroconvulsive therapy, although some differences in the course of response were observed. CONCLUSION: These case reports suggest that Electroconvulsive therapy needs further evaluation for the treatment of resistant bipolar patients.

Pathological gambling in women: a review

Pathological gambling was only recently recognized as a psychiatric disorder (DSM-III, APA, 1980). Most studies of pathological gambling include only male subjects. Despite the paucity of information, it is likely that at least one-third of pathological gamblers are women. The objective of this article is to review clinical and epidemiological characteristics of female gamblers as compared to their male counterparts. MEDLINE and PsycINFO were searched for investigational studies and reviews of the past 10 years on clinical (sociodemographic, course and progression, psychiatric comorbidities, genetics, and personality) and epidemiological aspects of female gamblers. Other relevant articles were also selected from reference lists. It is concluded that the current literature indicates some common characteristics in female and male gamblers, but it also indicates the possibility that each gender may carry etiopathogenic differences that when better understood should lead to improved treatment and prevention strategies.

Impact of alcohol intoxication and withdrawal syndrome on social phobia and panic disorder in alcoholic inpatients

PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV) and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval). RESULTS: Only 1 (2.4%) patient presented panic disorder throughout life, and 9 (21.9%) had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39%) alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.

Prevenção terciária em saúde mental : novas respostas em Portugal

RESUMO - Apresenta-se a caracterização e a descrição das novas respostas, bem como dos dispositivos que as permitiram organizar, quanto à prevenção terciária em saúde mental em Portugal. Detalha-se a Região de Lisboa e Vale do Tejo por ser a que mais estruturas criou e que foi alvo do estudo das autoras. Até ao final de 2001 beneficiavam 754 pessoas desta oferta de serviços no nosso país, das quais 473 na Região de Lisboa e Vale do Tejo. A maior parte destes beneficiários, 299, participa em actividades de fórum sócio-ocupacional, estando 99 pessoas inseridas em estruturas residenciais. Daí que se entenda que houve uma melhoria quanto à cobertura de necessidades em termos de prevenção terciária/ reabilitação no nosso país. Considera-se, contudo, que ainda muito está por fazer, uma vez que se continua muito aquém dos ratios de oferta de serviços internacionalmente recomendados. Considera-se desejável que se alargue e aprofunde este projecto, enquadrado com mais rigor em termos de diagnóstico de necessidades nacionais e com uma coordenação mais centralizada que potencie uma melhor gestão do seu quadro de exigências.
