Clinical and epidemiological study of leprosy cases in the University Hospital of Brasília: 20 years - 1985 to 2005

Hansen's disease, also known as leprosy, is an infectious disease still prevalent in Brazil. It is a chronic illness with acute immunological phenomena known as leprosy reactions. In the Federal District of Brazil, the University Hospital of Brasília is the reference centre for leprosy care. The study aimed to characterize the clinical and epidemiological profile of Hansen's disease patients at the University Hospital of Brasília, by descriptive, retrospective analysis of 1,124 patients over the period from 1985 to 2005. The pattern of leprosy in this study demonstrated that type 2 leprosy reactions were common, especially in the lepromatous form and presented a direct correlation with the bacilloscopic index. The prevalence and frequency of severe complications, such as leprosy reactions, emphasize the importance of the ongoing study of leprosy and the need for continual improvement in the scope of knowledge concerning its treatment.

Advanced megaesophagus (Group III) secondary to vector-borne Chagas disease in a 20-month-old infant

The authors report the case of a female infant with Group III (or Grade III) megaesophagus secondary to vector-borne Chagas disease, resulting in severe malnutrition that reversed after surgery (Heller technique). The infant was then treated with the antiparasitic drug benznidazole, and the infection was cured, as demonstrated serologically and parasitologically. After follow-up of several years without evidence of disease, with satisfactory weight and height development, the patient had her first child at age 23, in whom serological tests for Chagas disease yielded negative results. Thirty years after the initial examination, the patient's electrocardiogram, echocardiogram, and chest radiography remained normal.

A consumer research project as the basis for the development of a marketing plan for a new spirit brand producing gin in Germany

This work project is about developing a marketing plan for a new gin brand in Germany. It is based on consumer and market research, including Portugal as a trend market for the qualitative research. For the undertaking it is seen as fundamental to understand the industry as well as the consumer needs, attitudes and preferences. Furthermore, it is important to consider the estimation of opinion leaders and trendsetters in the industry. In this context it turned out that barkeepers have a key-influencing role for the stimulation of demand. Based on the insights from this research as well as on the gained market knowledge, the marketing plan was developed. The goal is to convince other brand users to switch brands.

Orifice diseases project - experience of the "Hospital das Clínicas" University of São Paulo Medical Center in day-hospital of anorectal disease

The treatment of malignant or benign colorectal pathologies that require more complex management are priorities in tertiary hospitals such as "Hospital das Clínicas" University of São Paulo Medical Center (HCFMUSP). Therefore, benign, uncomplicated orifice conditions are relegated to second place. The number of patients with hemorrhoids, perianal fistulas, fissures, condylomas and pilonidal cysts who seek treatment at the HFMUSP is very great, resulting in over-crowding in the outpatient clinics and a long waiting list for recommended surgical treatment (at times over 18 months). The authors describe the experience of the HCFMUSP over an eight-day period with day-hospital surgery in which 140 patients underwent surgery. Data was prospectively taken on the patients undergoing surgery for benign orifice pathologies including age, sex, diagnosis, surgery performed, immediate and late postoperative complications, and follow-up. 140 patients operated on over eight days were studied. 68 were males (48.75%) with ages ranging from 25 to 62 (mean 35.2 yrs.). Hemorrhoids was the most frequent condition encountered (82 hemorrhoidectomies, 58.6%), followed by perineal fistula (28 fistula repairs, 20.0%). The most common complication was headache secondary to rachianesthesia occurring in 9 patients (6.4%). One patient (0.7%) developed bleeding immediately PO that required reoperation. Mean follow-up was 104 days. Day-surgery characterized by quality care and low morbidity is feasible in tertiary public hospitals, permitting surgery for benign orifice pathologies on many patients within a short period of time.

Renal and urinary findings in 20 patients with Williams-Beuren syndrome diagnosed by fluorescence in situ hybridization (FISH)

PURPOSE: Williams-Beuren syndrome is a rare multiple anomalies/mental retardation syndrome caused by deletion of contiguous genes at chromosome region 7q11.23. The aim of this work was to determine the frequency and the types of renal and urinary tract anomalies in 20 patients with Williams-Beuren syndrome. METHODS: The fluorescence in situ hybridization test using a LSI Williams syndrome region DNA probe was performed for all 20 patients to confirm the diagnosis of Williams-Beuren syndrome. A prospective study was performed in order to investigate renal and urinary aspects using laboratory assays to check renal function, ultrasonography of the kidneys and urinary tract, voiding cystourethrogram and urodynamics. RESULTS: Deletion of the elastin gene (positive fluorescence in situ hybridization test) was found in 17 out of 20 patients. Renal alterations were diagnosed in 5 of 17 (29%) the patients with the deletion and in 1 of 3 patients without the deletion. Fourteen patients with the deletion presented dysfunctional voiding. Arterial hypertension was diagnosed in 3 patients with deletions and 1 of these presented bilateral stenosis of the renal arteries. CONCLUSIONS: Due to the high incidence of renal and urinary abnormalities in Williams-Beuren syndrome, performing a systematic laboratory and sonographic evaluation of the patients is recommended.

Rendimento e condições de desdobro de 20 espécies de madeiras da Amazônia

Neste trabalho, procedeu-se à avaliação do rendimento e condições de desdobro de espécies de madeiras tropicais provenientes da área de construção da UHE-Balbina e da reserva florestal ZF-2. Utilizou-se o mínimo de 5 toras por espécie para a coleta das informações sobre diâmetro médio das toras, grau de conicidade das toras, grau de dificuldade corte, índice de durabilidade do fio, rendimento e densidade básica. O rendimento médio das espécies estudadas variou entre 41,9 e 61,8%, sendo que 6 espécies (caroXXX, cedrorana, cupiúba, louro aritu, madioqueira e quarubarana), apresentaram rendimento médio acima da faixa normal de 45 a 55%, considerada para madeiras tropicais. Entre as espécies estudadas, as toras de Brasimum rubescens (pau rainha) e as Manilkara huberi (maçarandba), foram as que apresentaram maior grau de dificuldade de corte das toras entre as diferentes espécies. As fórmulas apresentadas neste trabalho permitem estimar o volume de madeira serrada produzido a partir das toras de uma determinada espécie.

On project finance and the first road concession in Portugal

In broad sense, Project Financing1 as a mean of financing large scale infrastructural projects worldwide has had a steady growth in popularity for the last 20 years. This growth has been relatively unscathed from most economic cycles. However in the wake of the 2007 systemic Financial Crisis, Project Financing was also in trouble. The liquidity freeze and credit crunch that ensued affected all parties involved. Traditional Lenders, of this type of financial instrument, locked-in long-term contractual obligations, were severely hit with scarcity of funding compounded by rapidly increasing cost of funding. All the while, Banks were “rescued” by the concerted actions of Central Banks and other Multi-Lateral Agencies around the world but at the same time “stressed” by upcoming regulatory effort (Basel Committee). This impact resulted in specific changes to this type of long-term financing. Changes such as Commercial Banks’ increased risk aversion; pricing increase and maturities decrease of credit facilities; enforcement of Market Disruption Event clauses; partial responsibility for project risk by Multilateral Agencies; and adoption of utility-like availability payments in other industrial sectors such as transportation and even social infrastructure. To the extent possible, this report is then divided in three parts. First, it begins with a more instructional part, touching academic literature (theory) and giving the Banks perspective (practice), but mostly as an overview of Project Finance for awareness’ sake. The renowned Harvard Business School professor – Benjamin Esty, states2 that Project Finance is a “relatively unexplored territory for both empirical and theoretical research” which means that academic research efforts are lagging the practice of Project Finance. Second, the report presents a practical case regarding the first Road Concession in Portugal in 1998 ending with the lessons learned 10 years after Financial Close. Lastly, the report concludes with the analysis of the current trends and changes to the industry post Financial Crisis of the late 2000’s. To achieve this I’ll reference relevant papers, books on the subject, online articles and my own experience in the Project Finance Department at a major Portuguese Investment Bank. Regarding the latter, with the signing of a confidentiality agreement, I’m duly omitting sensitive and proprietary bank information.

Investigação do potencial antioxidante e anticolinesterásico de 20 espécies da família Lauraceae

Lauraceae é uma das famílias mais importantes na floresta amazônica. Diversas de suas espécies apresentam em sua composição substâncias com pronunciadas atividades biológicas. Nesse trabalho, os extratos obtidos em etanol de galhos e folhas de 20 espécies de Lauraceae foram coletados na Reserva Florestal Ducke e avaliados quant o às atividades antioxidante frente ao radical livre 2,2-difenil-1-picrilhidrazila(DPPH) e inibidora da enzima acetilcolinesterase. O extrato dos galhos de Licaria martinianal apresentou a maior capacidade de sequestro do radical DPPH (6,96 µg.mL-1),mas os extratos de Ocotea iminor foram os mais ativos na inibição da enzima acetilcolinesterase, apresentando também pronunciada atividade antioxidante. O perfil de atividade antioxidante e anticolinesterásico destes extratos está sendo relatado pela primeira vez neste trabalho.

Comparative leaf morphological analysis of 20 species of Chrysobalanaceae

Morphological studies focusing on vegetative traits are useful in identifying species when fertile material is not available. The aim of this study was to assess the application of comparative leaf morphology to identify species of the Chrysobalanaceae family. The morphological observations were made with a stereomicroscope. We used the diaphanization technique for viewing venation details. It is shown the descriptions of the leaf morphology, illustrations and an identification key for 20 species from genera Couepia, Licania and Parinari (Chrysobalanaceae) occurring in the Adolpho Ducke Forest Reserve, Manaus, AM, Brazil. The key was constructed using the DELTA (DEscription Language for TAxonomy) software. Leaf traits such as the presence of intersecondary venation and the type of insertion of secondary veins were recorded for each species. These morphological leaf traits are reliable for identifying species of Chrysobalanaceae

Programa de tratamento assertivo na comunidade (PACT) e gerenciamento de casos (case management): revisão de 20 anos da literatura

OBJETIVO: Realizar uma revisão de estudos sobre programa de tratamento assertivo na comunidade (PACT) e case management para verificar se os resultados demonstram desfechos mais favoráveis quando tais modelos são implementados na rede comunitária de assistência para portadores de doença mental grave e persistente. MÉTODOS: A coleta de artigos - publicados entre 1985 e 2005 - foi realizada em duas etapas: a primeira, na base de dados PubMed, com expressões-chave mental health, community care, services evaluation e seleção de artigos cuja temática era PACT e case management, e a segunda, no banco de dados da revista Psychiatric Services, com palavras-chave assertive community treatment, PACT e case management. Foram desconsiderados estudos que analisavam serviços exclusivos para crianças, idosos e pacientes com diagnóstico único de abuso de álcool/drogas; abordavam unicamente os custos da intervenção e se referiam exclusivamente a serviços hospitalares. RESULTADOS: A partir da leitura dos 73 estudos selecionados, os autores descreveram oito categorias nas quais os artigos foram agrupados, visto que um artigo poderia pertencer a mais de uma categoria. CONCLUSÕES: O PACT e o case management são estratégias importantes e reconhecidamente mais eficazes, quando comparados a outros modelos de cuidado, em trazer evoluções favoráveis para indivíduos com doença mental grave e persistente.

Intrauterine ductus arteriosus constriction: analysis of a historic cohort of 20 cases

OBJECTIVE: To describe the relative incidence, presentation, and evolvement of fetuses with early ductus constriction. METHODS: Twenty fetal echocardiograms indicating ductus constriction were reviewed in a population of 7000 pregnants. RESULTS: The cases were divided into group A (related to maternal use of cyclooxygenase inhibitors [n=7] and group B (idiopathics [n=13]). Mean gestational age was 32.5±3.1 (27-38) weeks and maternal age was 28.2±8.5 (17-42) years. Mean systolic velocity in the ductus was 2.22±0.34 (1.66-2.81) m/s, diastolic velocity 0.79±0.28 (0.45-1.5) m/s, and pulsatility index 1.33±0.36 (0.52-1.83). Two cases of ductal occlusion were noted. In 65% of the cases, an increase occurred in the right cavities; in 90% of the cases, tricuspid or pulmonary regurgitation, or both, occurred, with functional pulmonary atresia in 1 case. Diastolic velocity was greater in group A (1.13±0.33) than in group B (0.68±0.15) (P=0.008). The other data were similar in the 2 groups. The evolvement was not favorable in 4 patients from group B, including 1 death and 2 cases of persistent pulmonary hypertension. CONCLUSION: The high incidence of idiopathic constriction of the ductus arteriosus suggests that its diagnosis is underestimated and that many cases of persistence of fetal circulation in newborns may be related to constriction of the ductus arteriosus not diagnosed during intrauterine life. Group B had a lower severity but a risk of an unfavorable evolvement, suggesting a distinct alteration.
