FIRST CASE OF HUMAN INFECTION BY Bertiella studeri (Blanchard, 1891) Stunkard,1940 (Cestoda; Anoplocephalidae) IN BRAZIL

SUMMARY Cestodes of the Bertiella genus are parasites of non-human primates found in Africa, Asia, Oceania and the Americas. Species Bertiella studeri and Bertiella mucronatacould, accidentally, infect human beings. The infection occurs from ingestion of mites from the Oribatida order containing cysticercoid larvae of the parasite. The objective of this report is to register the first case of human infection by Bertiella studeri in Brazil. Proglottids of the parasite, found in the stool sample of a two-and-a-half-year-old child, were fixed, stained and microscopically observed to evaluate its morphological characteristics. Eggs obtained from the proglottids were also studied. The gravid proglottids examined matched the description of the genus Bertiella. The eggs presented a round shape, with the average diameter of 43.7 µm, clearly showing the typical pyriform apparatus of B. studeri. The authors concluded that the child was infected with Bertiella studeri,based on Stunkard's (1940) description of the species. This is the fifth case of human Bertiellosis described in Brazil through morphometric analysis of the parasite, the third in Minas Gerais State and the first diagnosed case of Bertiella studeriin Brazil.

FIRST REPORT OF CUTANEOUS LEISHMANIASIS CAUSED BY Leishmania (Leishmania) infantum chagasi IN AN URBAN AREA OF RIO DE JANEIRO, BRAZIL

SUMMARY American tegumentary leishmaniasis (ATL) is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL) are caused by Leishmania (Viannia) braziliensis, while cases of visceral leishmaniasis (VL) are caused by Leishmania (Leishmania) infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L.) infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L.) infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement). We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.

Adequate Seal and No Endoleak on the First Postoperative Computed Tomography Angiography as Criteria for No Additional Imaging Up to 5 Years after Endovascular Aneurysm Repair

OBJECTIVE: Intensive image surveillance after endovascular aneurysm repair is generally recommended due to continued risk of complications. However, patients at lower risk may not benefit from this strategy. We evaluated the predictive value of the first postoperative computed tomography angiography (CTA) characteristics for aneurysm-related adverse events as a means of patient selection for risk-adapted surveillance. METHODS: All patients treated with the Low-Permeability Excluder Endoprosthesis (W. L. Gore & Assoc, Flagstaff, Ariz) at a tertiary institution from 2004 to 2011 were included. First postoperative CTAs were analyzed for the presence of endoleaks, endograft kinking, distance from the lowermost renal artery to the start of the endograft, and for proximal and distal sealing length using center lumen line reconstructions. The primary end point was freedom from aneurysm-related adverse events. Multivariable Cox regression was used to test postoperative CTA characteristics as independent risk factors, which were subsequently used as selection criteria for low-risk and high-risk groups. Estimates for freedom from adverse events were obtained using Kaplan-Meier survival curves. RESULTS: Included were 131 patients. The median follow-up was 4.1 years (interquartile range, 2.1-6.1). During this period, 30 patients (23%) sustained aneurysm-related adverse events. Seal length <10 mm and presence of endoleak were significant risk factors for this end point. Patients were subsequently categorized as low-risk (proximal and distal seal length ≥10 mm and no endoleak, n = 62) or high-risk (seal length <10 mm or presence of endoleak, or both; n = 69). During follow-up, four low-risk patients (3%) and 26 high-risk patients (19%) sustained events (P < .001). Four secondary interventions were required in three low-risk patients, and 31 secondary interventions in 23 high-risk patients. Sac growth was observed in two low-risk patients and in 15 high-risk patients. The 5-year estimates for freedom from aneurysm-related adverse events were 98% for the low-risk group and 52% for the high-risk group. For each diagnosis, 81.7 image examinations were necessary in the low-risk group and 8.2 in the high-risk group. CONCLUSIONS: Our results suggest that the first postoperative CTA provides important information for risk stratification after endovascular aneurysm repair when the Excluder endoprosthesis is used. In patients with adequate seal and no endoleaks, the risk of aneurysm-related adverse events was significantly reduced, resulting in a large number of unnecessary image examinations. Adjusting the imaging protocol beyond 30 days and up to 5 years, based on individual patients' risk, may result in a more efficient and rational postoperative surveillance.

Short QT Syndrome Presenting As Syncope: How Short Is Too Short?

We report the case of a 52-year-old man who presented to our emergency department (ED) after three episodes of syncope in the seven hours before admission. During his stay in the ED he had recurrent ventricular tachycardia (VT) requiring external electrical cardioversion. A 12-lead electrocardiogram (ECG) showed a short QT (SQT) interval (270 ms, QTc 327 ms), with frequent R-on-T extrasystoles triggering sustained polymorphic VT. After exclusion of other precipitating causes, the patient was diagnosed as having SQT syndrome (SQTS) according to the Gollob criteria. To our knowledge, this is the first known documentation of an SQT-caused arrhythmic episode on a 12-lead ECG, as well as the first reported case of SQTS in Portugal. The patient received an implantable cardioverter-defibrillator and was discharged. At a follow-up assessment 14 months later he was symptom-free, interrogation of the device showed no arrhythmic events, and the ECG showed a QT interval of 320 ms (QTc 347 ms).

The MPs of the First Portuguese Republic: A prosopographic study

This paper summarises the results of the first systematic, detailed prosopographic study of the MPs – the deputados of the Lower Chamber - of the First Portuguese Republic (1910-1926). Data are presented both by legislature and for the overall period. Two kinds of background variables are explored: sociodemographic (birthplace, age, education and profession) and political (previous experience in other elite positions). Regime change in 1910 resulted in the replacement of the former political elite by homines novi. Most MPs of the Republican regime were born in small towns and communities, had carried out higher educational studies (with prevalence for law training), were mainly drawn from the professions (practising lawyers and doctors) and the Army, and were elected for the first-time at relatively young ages. Parliamentary turnover was high (two-thirds of the representatives held just one mandate) and a large proportion of MPs had a consistent connection (birth, family ties, occupation) to the constituencies to which they had been elected.

Contribuição para a adaptação cultural do Neck Disability Index e caraterização da prática de fisioterapia em pacientes com dor crónica cervical

RESUMO: Objetivo: Este trabalho teve como objetivo contribuir para o processo de adaptação cultural do Neck Disability Index (NDI), através da análise da sua unidimensionalidade e do estudo da sua fiabilidade (consistência interna e fiabilidade teste-reteste), validade de constructo e poder de resposta. De igual forma pretendeu-se caraterizar a intervenção realizada pela fisioterapia e os resultados obtidos em pacientes com Dor Cervical Crónica (DCC). Introdução: A dor cervical é um problema cada vez mais comum nos países industrializados, constituindo uma das três condições mais frequentemente reportadas por queixas de origem músculo-esquelética. A sua incidência é um fenómeno em crescimento, com custos implicados para a sociedade. Desta forma reconhece-se a importância de um instrumento que monitorize a evolução da incapacidade funcional associada à DCC. O NDI é atualmente o instrumento de avaliação mais recomendado para avaliar a incapacidade funcional associada à dor cervical. Foi traduzido e adaptado à língua portuguesa, mas à data não foi realizada nenhuma avaliação das suas propriedades psicométricas. Por outro lado, apesar de a literatura referir que os serviços de Fisioterapia são extremamente procurados por indivíduos com DCC, em Portugal, a informação sobre a sua prática nesta condição clínica é escassa ou mesmo inexistente. Assim, e sendo a incapacidade nas atividades funcionais uma das variáveis de maior impacto da DCC e ao mesmo tempo um dos resultados principais da intervenção da Fisioterapia, importa por um lado possuir instrumentos capazes de avaliar o nível de incapacidade funcional e a sua mudança, e por outro, aferir qual a intervenção realizada pela Fisioterapia e quais os resultados obtidos. Metodologia: Realizou-se um estudo de coorte prospetivo com uma amostra de conveniência, do tipo não probabilístico, constituída por 88 pacientes com DCC de origem músculo-esquelética e causa não traumática referenciados para 6 serviços de fisioterapia / medicina física e de reabilitação de clínicas e centros de reabilitação, sendo elegíveis todos os pacientes que cumprissem os critérios de inclusão e exclusão estabelecidos. Os pacientes foram avaliados em três momentos pré-definidos: antes do início das sessões de fisioterapia ou na 1ª semana de tratamento; 4 a 7 dias após a 1ª avaliação; e 7 semanas após o início da fisioterapia. Para verificação da unidimensionalidade do NDI, procedeu-se a uma Análise Fatorial Exploratória. As propriedades psicométricas do NDI avaliadas foram a Fiabilidade (consistência interna e fiabilidade teste-reteste), a Validade de Constructo e o Poder de Resposta. Posteriormente procedeu-se à caraterização da prática da fisioterapia quanto às modalidades utilizadas, número de sessões de tratamento e duração do episódio de cuidados. Adicionalmente descreveu-se os resultados obtidos após a intervenção da fisioterapia ao nível da dor e incapacidade. Resultados: os resultados obtidos foram positivos e significativos, com a confirmação da unidimensionalidade do NDI, sendo que em todos os critérios seguidos o fator mínimo retido foi de um. Na avaliação da consistência interna o valor obtido foi acima do mínimo aceitável (α Cronbach = 0,77), enquanto o valor de fiabilidade teste-reteste foi elevado (CCI =0,95). De igual forma, os resultados foram positivos para a validade de constructo, obtendo-se uma associação positiva do NDI com a Escala Numérica da dor (END). O valores de poder de resposta reportaram uma Área Abaixo da Curva de 0,63 (IC 95%=0,51-0,75), com valor de Diferença Mínima Clinicamente importante de 5,5 pontos (sensibilidade = 69,6%; especificidade = 43,6%). Relativamente á intervenção de fisioterapia em casos de DCC verificou-se que as características da prática da fisioterapia reportadas neste relatório são de difícil comparação ou análise dada a escassez ou inexistência de trabalhos publicados sobre este assunto em pacientes com DCC. No entanto, neste estudo, encontraram-se reduções significativas na intensidade da dor e incapacidade funcional após a intervenção de fisioterapia (z= -7,16; p<0,001 e t= 10,412, p<0,05, respetivamente). Conclusão: Os resultados do presente estudo revelam que o NDI-VP possui uma boa Fiabilidade, Validade de Constructo e Poder de Resposta. Revela ainda que a intervenção da fisioterapia em casos de DCC, apesar da escassez de trabalhos publicados, proporciona uma redução significativa dos níveis de dor e incapacidade em pacientes com DCC.--------------- ABSTRACT:Objective: the aim of this study was to contribute for the process of cultural adaption of the Neck Disability Index (NDI), through the analysis of his unidimensionality and the study of his reliability (internal consistency and test-retest reliability), construct validity and responsiveness. At the same time it pretends to characterize the intervention performed by physical therapy and the results in patients with Chronic Neck Pain (CNP). Introduction: neck pain is a common problem in the industrialized countries, since is one of the three most reported conditions by complaints with musculoskeletal origin. His incidence is a growth phenomena that implicate great costs to society. Therefore the importance of an instrument that monitories the evolution of the functional disability associated to CNP is recognized. Nowadays, NDI is the instrument most recommended to evaluate functional disability associated to neck pain. It has been translated and adapted to portuguese but, till now, no evaluation of his psychometric proprieties has been completed. In the other hand, despite literature refers that physical therapy services are extremely searched by patients with neck pain, in Portugal, the information about practice in this clinical condition is very few or inexistent. Therefore, and since disability in the functional activities is one of the variables with most impact of CNP and, at the same time, one of the main results of physical therapy interventions, it’s important to have instruments capable of evaluate the level of functional disability and his change, and also calculate which intervention of physical therapy is most appropriate and his results. Methodology: it was used a prospective cohort study with a convenience sample, non-probabilistic, consisting of 88 patients with CNP of musculoskeletal origin and non-traumatic cause, referred to 6 physical therapy services of clinics and rehabilitation centers, and fulfilled the inclusion and exclusion criteria established. Patients were evaluated in three pre-defined moments: before the beginning of physical therapy or during the first week of treatment; 4 to 7 days after the first evaluation; and 7 weeks after beginning of physical therapy. To verify NDI unidimensionality, we run an Exploratory Factorial Analysis. NDI psychometric proprieties evaluated were reliability (internal consistency and test-retest reliability), construct validity and responsiveness. Subsequently, it was proceeded the characterization the practice of physical therapy regarding to the modalities used, the number of treatment sessions and duration of the episode of care. Additionally it was described the results obtained after the intervention of the physical therapy, the level of pain and the disability. Results: results were positive and significant, with the confirmation of the NDI unidimensionality, since in every followed criteria the minimal retained factor was one. In the evaluation of internal consistency the value was above the minimal accepted (α Cronbach = 0,77), and the test-retest reliability value was high (CCI =0,95). Results were positive to construct validity, with an positive association of the NDI with Numeric Rating Scale (NRS). Responsiveness values reported an Area Under Curve (AUC) of 0,63 (IC 95%=0,51-0,75) with a Minimal Important Detectable Change (MIDC) of 5,5 points (sensitivity = 69,9%; specificity = 43,6%). Regarding physical therapy interventions in CNP, it was verified that the physical therapy characteristics reported are difficult to compare or analyze since there are very few published studies about this topic. However, in this study, significant reductions were founded in pain intensity and functional disability after intervention(z= -7,16; p<0,001 and t= 10,412, p<0,05, respectively).Conclusion: present study results reveals that NDI has an good reliability, construct validity and responsiveness. It also reveals that physical therapy intervention in CNP, beside few studies published, result in a significant reduction of pain and disability levels in patients with CNP.

The vaccination of h uman beings with live avirulent vaccine of Trypanosoma cruzi: A two year follow-up of the first two cases

A two year follow-up of the first two volunteers vaccinated icith the live PF Trypanosoma cruzi strain demonstrated that the parasitological and clinical test were negative during and after that period. Of the serological tests employed, the CFT presented, in only one case, conflicting results, particulary in one laboratory and among different laboratories. However negative results were greater than all doubtful and positive one combined. The IFT icere negative in both patients. Some comments are made about the sensibility and specificity of these tests. The author concluded that the vaccine, in spite of the very large dose used in these cases, seems to be safe for human beings.

First Diabetic Retinopathy Prevalence Study in Portugal: RETINODIAB Study-Evaluation of the Screening Programme for Lisbon and Tagus Valley Region

BACKGROUND/AIMS: In Portugal, so far, there is no study or even accurate data on the prevalence of diabetic retinopathy (DR), based on a large representative sample and on a long-term follow-up. The objective of our study was to determine the prevalence of DR based on a national screening community-based programme. METHODS: A 5-year retrospective analysis of the RETINODIAB screening programme results was implemented in Lisbon and Tagus Valley area between July 2009 and October 2014. We estimated the prevalence of retinopathy for all patients with type 2 diabetes and studied the association between known risk factors and retinopathy emergence at their first screening. RESULTS: Throughout this period, from a total of 103 102 DR readable screening examinations, 52 739 corresponded to patients who attended RETINODIAB screening at entry. Globally, DR was detected in 8584 patients (16.3%). Of these, 5484 patients (10.4%) had mild non-proliferative (NP) DR, 1457 patients (2.8%) had moderate NPDR and 672 (1.3%) had severe NPDR. Finally, 971 patients (1.8%) had proliferative DR requiring urgent referral to an ophthalmologist. The presence of any DR, non-referable DR or referable DR was strongly associated with increasing duration of diabetes and earlier age at diagnosis. CONCLUSIONS: The prevalence rate of DR in our study (16.3%) was slightly lower than other published international data. The RETINODIAB network proved to be an effective screening programme as it improved DR screening in Lisbon and Tagus Valley surrounding area

Long-Term Survival (>25 Years) of Deceased Donor Kidney Transplant Recipients: a Single-Center Experience

INTRODUCTION: The aim of this preliminary work is to analyze the clinical features of 52 patients with a functional transplanted kidney for >25 years (all first transplant and all deceased donor recipients) and to compare with a similar though more complete study from Hôpital Necker-Paris 2012. METHODS: The mean graft survival at 25 years is 12.7% and at 30 years is 10%. The actual mean serum creatinine concentration is 1.3 mg/L. We analyzed recipient age (mean, 35.9 years) and gender (29 men and 23 women). Donor age was 26.7 ± 10.3 years. Seven patients (13.4%) were transplanted with 1 HLA mismatch, 42.3% with 2 mismatches, and 44.2% with 3 mismatches. Mean cold ischemia time was 15.45 ± 7.7 hours. Of the recipients, 76% had immediate graft function; 38% experienced 1 acute rejection episode and 4 patients had 2 rejection crises. The initial immunosuppressive regimen was azathioprine (AZA) + prednisolone (Pred) in 14 patients, cyclosporin (CSA) + Pred in 13 patients, and CSA + AZA + Pred in 25 patients. Of these patients, 19% maintained their initial regimen, and 54% (28 patients) were very stable on a mixed CSA regimen for >25 years. RESULTS: We present the major complications (diabetes, neoplasia, and hepatitis C virus positivity). CONCLUSION: Our results in deceased donor kidney recipients for >25 years are similar to the mixed population (deceased donors and living donors) presented by the Necker group, although 54% of our patients remain on CSA immunosuppression, contradicting the idea that its use is not compatible with good long-term kidney function in transplant recipients.

Renal Transplantation in HIV-Infected Patients: The First Portuguese Review

INTRODUCTION: With the introduction of combination antiretroviral therapy (cART), prognosis of human immunodeficiency virus (HIV) infection has been improved and kidney transplantation (KT) in HIV-positive patients became possible. METHODS: We reviewed the demographic, clinical, laboratory, and therapeutic data of all the HIV-infected patients who underwent KT between 2009 (first KT in Portugal in a HIV-infected patient) and May 2014. Case accrual was through all Portuguese KT centers where a KT in an HIV-infected patient was performed. Patients were transplanted following the American and Spanish guideline recommendations that included maintenance on cART, undetectable plasma HIV RNA copies, and absolute CD4 counts of ≥ 200 cells/μL in the last 6 months. RESULTS: Fourteen KT were performed on men and 3 on women. The mean age of patients at the time of transplantation was 49.9 ± 11.7 years. HIV status was known for 12 ± 5 years. Eight patients had AIDS in the past and all patients received grafts from deceased donors. Twelve patients (64.7%) underwent induction therapy with basiliximab and 2 patients experienced early graft loss. In 2 patients, humoral rejection was diagnosed and in 3 patients, cellular rejection. Two patients died and an additional patient had early graft loss. CONCLUSION: KT is a possible, but challenging, renal replacement therapy in selected HIV-positive patients. Even in those with AIDS criteria in the past, when the disease is controlled, and after the reconstitution of the immune system with cART, KT can be performed. Nevertheless, the risk-benefit ratio for each patient needs to be taken in consideration.
