We report our experience with the diagnosis and treatment of 60 patients with American cutaneous leishmaniasis. They were infected in Panama (55), Brazil (4) or Colombia (I). Among 35 patients with a 3 week exposure in Panama, the mean maximum incubation period was 33 days (range 4-81 days). Diagnosis was delayed an average of 93 days after onset of skin lesions, due to the patient's delay in seeking medical attention (31 days), medical personnel's delay in considering the diagnosis (45 days), and the laboratory's delay in confirming the diagnosis (17 days). Forty-four patients (73%) developed ulcers typical of cutaneous leishmaniasis. Sixteen additional patients (27%) had atypical macular, papular, squamous, verrucous or acneiform skin lesions that were diagnosed only because leishmanial cultures were obtained. Of the 59 patients treated with pentavalent antimonial drugs, only 34 (58%) were cured after the first course of treatment. Lesions which were at least 2 cm in diameter, ulcerated, or caused by Leishmania braziliensis were less likely to be cured after a single course of treatment than were lesions smaller than 2 cm, nonulcerated or caused by Leishmania mexicana or Leishmania donovani.

RESUMO: Os psicofármacos desempenham um papel central no tratamento das doenças mentais. Apesar das divergências verificadas nos padrões de prescrição de psicofármacos intra e inter países, diversos estudos têm alertado para os riscos da polifarmácia e da sobredosagem, particularmente de antipsicóticos. Em Portugal, o Plano Nacional de Saúde Mental 2007-2016 prevê a monitorização periódica do padrão de prescrição de psicofármacos. No entanto, apenas existem dados relativos à utilização de psicofármacos em ambulatório, faltando dados relativos ao padrão de prescrição nos cuidados especializados. Este estudo teve como principal objetivo estabelecer o Padrão de Prescrição de Psicofármacos em Unidades de Internamento Agudo de Serviços de Psiquiatria em Portugal e determinar a prevalência da polifarmácia e sobredosagem antipsicótica, de modo a recolher dados que possam servir de base para posteriores monitorizações. Métodos: “Censo de 1 dia” da prescrição de psicofármacos em 12 Unidades de Internamento Agudo de Psiquiatria em Portugal, num total de 272 doentes. Resultados: A larga maioria (94,1%) dos doentes incluídos estava medicada com mais do que um psicofármaco. Apenas 1,1% dos doentes não tinham qualquer psicofármaco prescrito e 4,8% encontravam-se em monoterapia. A média de psicofármacos prescritos por doente era de 3,2±1,3, significativamente superior nos indivíduos do sexo feminino, naqueles com antecedentes de acompanhamento em consulta de psiquiatria, nos que tinham internamentos prévios e nos que estavam internados voluntariamente. As classes de psicofármacos mais prescritas de modo regular eram os antipsicóticos (prescritos a 87,5% dos doentes), as benzodiazepinas (81,2% dos doentes), os antidepressivos (39% dos doentes) e os estabilizadores de humor (31,6% dos doentes). Dos doentes medicados com antipsicóticos, 41,6% tinham prescritos pelo menos 2 antipsicóticos em associação e esta prescrição combinada era significativamente superior nos doentes com internamento prévio e naqueles que tinham prescrito um antipsicótico injetável de ação prolongada. Excluindo as prescrições em SOS, encontraram-se prescritas doses de antipsicóticos superiores às recomendadas em 13,9% dos doentes, os quais eram significativamente mais novos. A sobredosagem antipsicótica era significativamente superior nos doentes do sexo masculino, nos desempregados e reformados, naqueles com internamento prévio, nos que estavam internados compulsivamente, naqueles com diagnóstico de “esquizofrenia ou outra psicose”, naqueles medicados com antipsicóticos em associação e nos que faziam antipsicóticos injetáveis de ação prolongada. Incluindo as prescrições de antipsicóticos em SOS, presentes em mais de metade dos doentes, a percentagem de doentes em sobredosagem antipsicótica atingia os 49,2%. Conclusão: Os resultados são indicadores de práticas de prescrição divergentes das recomendadas, o que pode ter implicações clínicas e económicas. Parece imperativo otimizar a prescrição de psicofármacos nas unidades de internamento agudo de psiquiatria em Portugal, no sentido de melhorar a qualidade dos serviços prestados ---------------- ABSTRACT: Psychotropic drugs play a central role in the treatment of mental disorders. Despite the variation in patterns of psychotropic prescription within and between countries, several studies have warned about the risks of prescribing more than one psychotropic drug at a time and “high-doses”, particularly antipsychotics. The Portuguese National Mental Health Plan (2007–2016) includes regular monitoring of patterns of psychiatric drug prescription. However, there is only available data on the pattern of use in outpatients, but no information regarding prescribing patterns at the level of specialized care. This study aimed to establish psychotropic drug prescribing patterns in acute psychiatric wards across Portugal and to determine the prevalence of antipsychotic polypharmacy and “high-doses” treatment, in order to collect data that can serve as a baseline for future monitoring. Methods: "One day census" of psychotropic drug prescribing in 12 Acute Inpatient Psychiatry Units in Portugal, in a total of 272 patients. Results: The majority (94.1%) of patients were treated with more than one psychotropic drug. Only 1.1% of patients had no psychotropic drugs prescribed and 4.8% were on monotherapy. The average prescribed psychotropics per patient was 3.2 ± 1.3, significantly higher in females, in patients with a psychiatry history, in patients with previous admissions and in patients admitted voluntarily. The most commonly prescribed classes of psychotropic drugs on a regular basis were: antipsychotics (87.5% of patients), benzodiazepines (81.2% of patients), antidepressants (39% of patients) and mood stabilizers (31.6% of patients). Of patients taking antipsychotics, 41.6% had at least 2 antipsychotics prescribed in combination, and this prescription combination was significantly higher in patients with previous hospitalization and those who had been prescribed a long-acting injectable antipsychotic. Excluding p.r.n. prescriptions, we verified higher than recommended antipsychotic doses in 13.9% of patients, which were significantly younger. Antipsychotic “high-doses” was significantly higher in males, unemployed and pensioner patients, patients with previous hospitalization, involuntary admitted patients, those diagnosed with "schizophrenia or other psychosis", patients with a combination of 2 or more antipsychotics and in patients with long-acting injectable antipsychotics. Including antipsychotics p.r.n. prescriptions, present in more than a half of patients, the percentage of those on antipsychotic “high-doses” reached 49.2%. Conclusion: These results are indicative of prescribing practices divergent of those that are recommended, and this may have clinical and economic implications. It seems imperative to optimize the prescription of psychotropic drugs in Portuguese Acute Inpatient Psychiatry Units, in order to improve the quality of services provided.

Atypical P. vivax cases reported in Manaus municipality led us to detect a genetic isolate of P. vivax. Variable regions of SSUrRNA were examined from the initial time of infection and in the two recrudescences/relapses from a patient exhibiting chloroquine and primaquine resistance. A unique isolate, found at all stages of infection, suggests the presence of a clonal expansion.

Verapamil, was assayed to record its modulating effect upon Brazilian Plasmodium falciparum isolates resistant to chloroquine. Other cardiovascular drugs known to be modulating agents in resistant malaria and/or multidrug-resistant neoplasias, including nifedipine, nitrendipine, diltiazem and propranolol, were also evaluated. Concentrations similar to those for cardiovascular therapy were used in the in vitro microtechnique for antimalarial drug susceptibility. Intrinsic antiplasmodial activity was observed from the lowest concentrations without a significant modulating action. Other reported modulating agents, such as the antipsychotic drug trifluoperazine and the antidepressants desipramine and imipramine, demonstrated similar responses under the same experimental conditions. Results suggest a much higher susceptibility of Brazilian strains, as well as an indifferent behaviour in relation to modulating agents.

The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV) and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001), showed a higher frequency of weight loss >10 kilos (p <0.001), had a higher rate of non-reaction result to the tuberculin skin test (p <0.001), a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001) and negative sputum culture for Mycobacterium tuberculosis (p = 0.001). Treatment failure was more common in those who were HIV positive (p <0.000). No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407). Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

RESUMO: OBJECTIVO: Avaliar as necessidades, incapacidade, qualidade de vida, satisfação com os serviços e as características sociodemográficas numa amostra de pacientes com esquizofrenia num Serviço de Psiquiatria, em Cabo Verde. MÉTODOS: Realizou-se estudo transversal com 122 doentes com recurso a instrumentos estruturados para as necessidades (CAN), incapacidade (WHODAS II), qualidade de vida (WHOQOL-BREF) e satisfação com os serviços (VSSS) e uma ficha para recolha de dados sociodemográficos. RESULTADOS: Os doentes eram maioritariamente do sexo masculino (73,8%) com uma idade média de 35,23 anos, uma escolaridade baixa (59,8%), solteiros (81.1%), residindo em meio urbano (72,1%) e desempregados (63,2%). A maioria estava a tomar medicação antipsicótica (97,5%), tinha história de internamento (76.2%), uma média de início da doença aos 23,43 anos e uma duração média de 11,80 anos. As necessidades referidas foram baixas e as facetas mais identificadas foram a informação, os subsídios e benefícios sociais, as actividades diárias, os contactos sociais e sofrimento psicológico. Cerca 20% dos participantes manifestaram uma incapacidade, sobretudo no domínio da da participação na sociedade (47,2%). A média da qualidade de vida foi 65,08 (desvio-padrão: 21,35), com o domínio psicológico a apresentar o valor mais alto (74,21, desvio-padrão: 14,87) e o ambiental o mais baixo (59,27, desvio-padrão: 15,15). A satisfação com os serviços foi avaliada de forma positiva nas dimensões satisfação global e competência dos profissionais. As dimensões informação, envolvimento dos familiares, eficácia e acesso tiveram avaliação insatisfatória. Os tipos de intervenções, com vários serviços pouco disponibilizados, tiveram uma satisfação relativa. DISCUSSÃO: Num contexto de carência, os resultados revelaram-se mais satisfatórios do que esperados, mas com grandes insuficiências no processo de cuidados. CONCLUSÃO: O estudo permitiu conhecer o processo de cuidados aos doentes com esquizofrenia e disponibilizou elementos para programas de cuidados.-----------ABSTRACT: OBJECTIVE: Assess needs, disability, quality of life, satisfaction with the services and the socio-demographic characteristics in a sample of patients with schizophrenia in a Psychiatric Service in Cape Verde. MATHODS: It was carried out a cross-sectional study with 122 patients using the structured instruments for the needs (CAN), disability (WHODAS II), quality of life (WHOQOLBREF),satisfaction with the services (VSSS) and socio-demographic data collection. RESULTS: The patients are mainly of the male sex (73.8%) with average age of 35.23 years old, low education level (59.8%), single (81.1%), living in urban area and unemployed (63.2%). Most of them were taking antipsychotic medication (97.5%), had a history of hospitalization (76.2%), an average of disease onset at 23.43 years old and an average duration of 11.80 years. The needs mentioned were low and the most identified facets were information, subsidies and social benefits, daily routines, social contacts and psychological distress. Around 20% of the participants expressed one disability, especially at the domain of the participation in the society (47.2%). The average quality of life was 65.08 (standard deviation: 21.35), with the domain of the psychological presenting the highest value (74.21, standard deviation: 14.87) and environmental the lowest (59.27, standard deviation: 15.15). The satisfaction with services was positively assessed in the dimensions of overall satisfaction and competency of the professionals. The dimensions information, family involvement, effectiveness and access had positive evaluation. The types of intervention with services poorly available had a relative satisfaction. DISCUSSION: In a context of shortage, the results were considered more satisfactory than expected, but with many inadequacies in the process of care. CONCLUSION: This study allowed to know the process of care to the patients with schizophrenia and provided elements for the programs of care.

Currently, Angola portrays a notorious economic growth and due to recent innovative legislations, it has become the major investment attracting pole, especially in Sub-Saharan Africa, having, thus, an extraordinary potentiality for a rapid and sustainable development, likely to place her in outstanding positions in the world economic ranking. Yet, such economic growth entails demanding levels of intensive investment in infrastructure, what has been reported of the Angolan Government to be unable to respond to, save if recurring to very high index of external debt, poisoning, in this way, the future budgeting of the country. Due to these infrastructure investment shortages, the cost of production remains highly onerous and the cost of life extremely unaffordable. On this account, the current study disserts about the contract of Project Finance; an alternative finance resource given as a viable solution for the private financing of infrastructure, aiming to demonstrate that such contractual figure, likewise the experience of several emerging economies and others, is a contract bid framework to take into account in today’s world. It refers to a financing technique – through which the Government may satisfy a common need (for example, the construction of a public domain or public servicing), without having to pay neither offer any collateral – based on a complex legal-financial engineering, arranged throughout a coalition of typical and atypical agreements, whereby it is mandatory to look back at the basic concepts of corporate law. More than just a simple financial study, the dissertation at stake analyses the nature and legal framework of Project Finance, which is a legally atypical and innominate contract, concluding that there is a relevant need for regulating and devoting a special legal regime in the Angolan jurisdiction for this promising legal form in the contemporary corporate finance world.

INTRODUCTION: Staphylococcal species are pathogens that are responsible for outbreaks of foodborne diseases. The aim of this study was to investigate the prevalence of enterotoxin-genes and the antimicrobial resistance profile in staphylococcus coagulase-negative (CoNS) and coagulasepositive (CoPS) isolates from black pudding in southern Brazil. METHODS: Two hundred typical and atypical colonies from Baird-Parker agar were inoculated on mannitol salt agar. Eighty-two mannitol-positive staphylococci were submitted to conventional biochemical tests and antimicrobial susceptibility profiling. The presence of coagulase (coa) and enterotoxin (se) genes was investigated by polymerase chain reaction. RESULTS: The isolates were divided into 2 groups: 75.6% (62/82) were CoNS and 24.4% (20/82) were CoPS. The biochemical tests identified 9 species, of which Staphylococcus saprophyticus (37.8%) and Staphylococcus carnosus (15.9%) were the most prevalent. Antimicrobial susceptibility tests showed resistance phenotypes to antibiotics widely administered in humans, such as gentamicin, tetracycline, chloramphenicol, and erythromycin. The coa gene was detected in 19.5% (16/82) of the strains and 4 polymorphic DNA fragments were observed. Five CoNS isolates carrying the coa gene were submitted for 16S rRNA sequencing and 3 showed similarity with CoNS. Forty strains were positive for at least 1 enterotoxin-encoding gene, the genes most frequently detected were sea (28.6%) and seb (27.5%). CONCLUSIONS: The presence of antimicrobial resistant and enterotoxin-encoding genes in staphylococci isolates from black pudding indicated that this fermented food may represent a potential health risk, since staphylococci present in food could cause foodborne diseases or be a possible route for the transfer of antimicrobial resistance to humans.

Introduction Nine cases of visceral leishmaniasis occurred recently in Barra Mansa, State of Rio de Janeiro, with a high mortality rate. Methods We reviewed the medical records of the patients. Results Eight were male; 7 were adults. Patients who died progressed to death quickly and presented with aggravating factors: systemic steroid therapy before diagnosis, bleeding, severe liver involvement, infection, and/or refusal to receive transfusion. Conclusions We warn clinicians to be aware of the emergence of visceral leishmaniasis in new areas and to keep in mind the possibility of atypical clinical pictures and aggravating factors, so timely diagnosis can be made and prompt and adequate treatment can be initiated.

INTRODUCTION: Friedreich's ataxia is a neurodegenerative disorder whose clinical diagnostic criteria for typical cases basically include: a) early age of onset (< 20 or 25 years), b) autosomal recessive inheritance, c) progressive ataxia of limbs and gait, and d) absence of lower limb tendon reflexes. METHODS: We studied the frequency and the size of expanded GAA and their influence on neurologic findings, age at onset, and disease progression in 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia - 19 typical and 6 atypical - using a long-range PCR test. RESULTS: Abnormalities in cerebellar signs, in electrocardiography, and pes cavus occurred more frequently in typical cases; however, plantar response and speech were more frequently normal in this group when the both typical and atypical cases were compared. Homozygous GAA expansion repeats were detected in 17 cases (68%) - all typical cases. In 8 patients (32%) (6 atypical and 2 typical), no expansion was observed, ruling out the diagnosis of Friedreich's ataxia. In cases with GAA expansions, foot deformity, cardiac abnormalities, and some neurologic findings occurred more frequently; however, abnormalities in cranial nerves and in tomographic findings were detected less frequently than in patients without GAA expansions. DISCUSSION: Molecular analysis was imperative for the diagnosis of Friedreich's ataxia, not only for typical cases but also for atypical ones. There was no genotype-phenotype correlation. Diagnosis based only on clinical findings is limited; however, it aids in better screening for suspected cases that should be tested. Evaluation for vitamin E deficiency is recommended, especially in cases without GAA expansion.

Cystic fibrosis is a genetic disease usually diagnosed by abnormal sweat testing. We report a case of an 18-year-old female with bronchiectasis, chronic P. aeruginosa infection, and normal sweat chloride concentrations who experienced rapid decrease of lung function and clinical deterioration despite treatment. Given the high suspicion ofcystic fibrosis, broad genotyping testing was performed, showing a compound heterozygous with deltaF508 and 3849+10kb C->T mutations, therefore confirming cystic fibrosis diagnosis. Although the sweat chloride test remains the gold standard for the diagnosis of cystic fibrosis, alternative diagnostic tests such as genotyping and electrophysiologic measurements must be performed if there is suspicion of cystic fibrosis, despite normal or borderline sweat chloride levels.

Keratoacanthoma generally occurs on the skin; it is rarely found in the conjunctiva. A case of a 34-year-old woman with a rapidly growing conjunctival mass is reported. The tumor was excised with a safety margin to exclude squamous cell carcinoma. Histopathologically it was crateriform and consistent with atypical keratoacanthoma. There has been no recurrence in 2 years of follow-up. Conjunctival keratoacanthoma is rare; differential diagnosis of conventional squamous cell carcinoma and keratoacanthoma can be difficult. We recommend complete surgical excision and careful follow-up of crateriform squamous proliferations.

The purpose of the present work is to analyse and provide kixikila legal framework under Angolan law. Kixikila, despite being a legally atypical agreement, is a socially typical contract, governed essentially by the practices and customs in Angola and concluded throughout the country. With the above purpose in mind, this thesis is structured in five chapters: the first one aims at better understanding its features and, therefore, it describes the kixikila in accordance with oral research, direct observation and the contributions of scholars that have examined this matter. The second chapter aims at qualifying the kixikila as a legal transaction. For this purpose, we have analysed its requirements, formation stages, content and form, characteristics, rights and obligations of the parties, effects and compliance. We have also covered the reasons that explain why this type of agreement shall be legally protected in line with the protection conferred upon other legal agreements, taking into account its economic and social function. The third chapter covers the vicissitudes which may occur during the term of the kixikila agreement, as well as the enforcement mechanisms in face of breach and its termination. The fourth chapter aims at qualifying this agreement by comparing its most relevant characteristics with those of typical agreements, with a view to determining its legal nature based upon the similarity with other contractual types. This chapter further makes a comparative synthesis between the contracts in analysis. The fifth chapter analyses the legal nature and legal framework applicable to kixikila taking into account mixed-purpose contracts and sui generis contracts. We conclude that practices and customs in Angola take precedence as regards kixikila. Lastly, we attach additional information, such as excerpts of interviews with some individuals intervening in kixikila, the functional structure of kixikila and examples of kixikila, as well as demonstrative lists of countries where this type of agreement takes place and the obligations arising therefrom.

From May to December, 1992 we studied the earthworm activity, as part of the ECOFIT Program at Surrão ( 30km from Boa Vista), verifying the duration of the activity and quantifying it through the casts deposited on the soil surface. Three transects were stablished: a 100m long in the savanna, a 40m in the transitional area and 100m long in the forest. Specimens were collected monthly along the transects according to the method proposed by TSBF and the casts were collected from the squares previously placed on the transects. Two earthworm species were found in the three areas: Pontoscolex roraìmensis and Pontoscolex corethrurus. The first species depositing its casts on the soil surface. Rainy season wich usually occurs from April to August, determined the duration of activity for the two species (however, 1992 was atypical in that rainy season, only started in May). P. roraìmensis produced casts in the three areas from May to August followed by aestivation. In the savanna, P. corethrurus started aestivation in the same period as P. roraìmensis but remained active until November in the two other areas. P. roraìmensiswas found up 50m from the forest border, being associated to the presence of Curatella americana and Byrsonima sp, two typical savanna bushes.
