ABSTRACT: Glanders is an infectious disease of equids caused by Burkholderia mallei, a facultative intracellular non-mobile Gram-negative bacterium that can be transmitted to other animals and humans. This study described glanders cases reported in the state of Maranhão, located within an Amazon-Cerrado transition region in northeastern Brazil, from 2007 to 2017. A database in an electronic spreadsheet (Microsoft Excel 2010) was developed containing information on the number of positive animals according to age, sex, purpose, year and month, municipality and mesoregion of origin of the animal. The descriptive analyzis was performed on data provided by the State Agency for Agricultural and Livestock Protection of the state of Maranhão (AGED), and by the official private laboratory. As the database did not have information data about negative animals, possible risk factors could not be evaluated. Among the total of 62,555 equids were evaluated by means of the complement fixation test (CFT), 59,036 were horses, 2,981 mules and 538 donkeys. Thirty-five samples (0.06%) reacted in the CFT. Five additional samples were by the western blot technique and three of them were positive. All the reactive horses (Equuscaballus) were from rural areas. Results presented here indicate that glanders may be endemic in the state of Maranhão and is a public health concern.

RESUMO: O mormo é uma doença infecciosa de equídeos causada por Burkholderia mallei, uma bactéria Gram-negativa intracelular, não móvel e facultativa que pode ser transmitida a outros animais e humanos. O objetivo deste estudo foi descrever os casos de mormo relatados no estado do Maranhão, em uma região de transição Amazônia-Cerrado do Nordeste do Brasil, no período de 2007 a 2017. Um banco de dados em uma planilha eletrônica (Microsoft Excel 2010) foi desenvolvido contendo informações sobre o número de animais positivos de acordo com a idade, sexo, finalidade, ano, mês, municípios e mesorregiões de origem do animal. A análise descritiva foi realizada sobre os dados fornecidos pela Agência Estadual de Defesa Agropecuária do Estado do Maranhão (AGED), e pelo laboratório privado oficial. Como o banco de dados não possui informações sobre animais negativos, possíveis fatores de risco não puderam ser avaliados. Entre o total de 62.555 equídeos foram avaliados com o teste de fixação do complemento (CFT), 59.036 eram cavalos, 2.981 mulas e 538 jumentos. Trinta e cinco (0,06%) amostras reagiram ao CFT. Cinco amostras adicionais foram testadas pela técnica de western blot e três foram positivas. Todos os animais positivos foram cavalos (Equus caballus) da área rural. Os resultados indicam que o mormo pode ser endêmico no estado do Maranhão e uma preocupação de saúde pública.

SUMMARY OBJECTIVE: The objective of this study was to investigate the reliability and construct validity of the Self-Estimated Functional Inability because of Pain questionnaire for workers in a sample of Brazilian workers with musculoskeletal pain. METHODS: This is a questionnaire validation study. Workers with musculoskeletal pain were included. Besides the Self-Estimated Functional Inability because of Pain questionnaire for workers, we used the following instruments to perform construct validity: the Work Ability Index and the Numerical Pain Rating Scale. A subsample answered the Self-Estimated Functional Inability because of Pain questionnaire for workers in two moments to calculate reliability by means of the intraclass correlation coefficient and internal consistency by means of the Cronbach’s alpha. RESULTS: A total of 190 Brazilian workers were included. Regarding the construct validity, we observed a correlation with magnitude above 0.50 between the Self-Estimated Functional Inability because of Pain questionnaire for workers and the Numerical Pain Rating Scale, given that these two instruments have similarity in the construct, and correlations above 0.30 between the Self-Estimated Functional Inability because of Pain questionnaire for workers and the domains 2, 3, and 4 of the Work Ability Index. Regarding reliability, we observed adequate reliability (intraclass correlation coefficient=0.864) and internal consistency (Cronbach’s alpha=0.807). CONCLUSION: The Self-Estimated Functional Inability because of Pain questionnaire for workers is a reliable and valid instrument to be used in Brazilian workers with musculoskeletal pain.

Abstract Due to the small number of records of Streblidae on bats, despite extensive study on these mammals in the state of Rio de Janeiro, a survey was carried out in an area of the Atlantic Forest. The present study was carried out at Bom Retiro Farm Natural Heritage Private Reserve. We captured 401 bats of 17 species, 13 genera, and four families; bat flies infested 221 bats of only four species. Carollia perspicillata (Linnaeus, 1758) has the highest fly diversity, with seven fly species: Trichobius joblingi (Wenzel, 1966) (n = 23), Megistopoda proxima (Séguy, 1926) (n = 15), Strebla guajiro (García & Casal, 1965) (n = 15), Aspidoptera falcata (Wenzel, 1976) (n = 6) Paratrichobius longicrus (Miranda Ribeiro, 1907) (n = 8), Paraeuctenodes similis (Wenzel 1976) (n = 3), and Trichobius anducei (Guerrero, 1998) (n = 1). Two species infested Platyrrhinus lineatus (É. Geoffroy, 1810): Aspidoptera falcata (n = 1) and Anastrebla caudiferae (Wenzel, 1996) (n = 1). Paradyschiria parvula (Falcoz, 1931) (n = 11) infested Noctilio leporinus (Linnaeus, 1758) and M. proxima (n = 12) and Trichobius uniformis (Curran, 1935) (n = 1) infested Sturnira lilium (É. Geoffroy, 1842). Sturnira lilium has the highest infestation rate, with ten out of 46 captured individuals parasitized, followed by Carollia perspicillata, with 33 out of 164 captured parasitized, and by P. lineatus with only two parasitized individuals out of ten. Among 97 streblid flies captured, M. proxima was the most abundant (27.83%), followed by T. joblingi (23.71%), and S. guajiro (15.46%). All remaining bat fly species represented 33%. Paradichyria parvula has the first record for Rio de Janeiro State.

Resumo A síndrome da costela cervical ocorre quando o triângulo intercostoescalênico é ocupado por uma costela cervical, deslocando o plexo braquial e a artéria subclávia anteriormente, o que pode gerar dor e espasmo muscular. O objetivo deste estudo é discutir sobre o diagnóstico da síndrome da costela cervical e as possibilidades de tratamento. Este desafio terapêutico descreve a condução clínica e cirúrgica de uma paciente de 37 anos com obstrução arterial em membro superior causada por costela cervical.

Abstract The cervical rib syndrome occurs when the interscalene triangle is occupied by a cervical rib, displacing the brachial plexus and the subclavian artery forward, which can cause pain and muscle spasms. The objective of this study is to discuss diagnosis of the cervical rib syndrome and treatment possibilities. This therapeutic challenge describes clinical and surgical management of a 37-year-old female patient with upper limb arterial occlusion caused by a cervical rib.

Resumo Contexto Pacientes com doença venosa crônica avançada são mais propensos a exigir outros procedimentos para recidiva de veias varicosas. Ainda não está estabelecido se a gravidade da insuficiência venosa é um fator que influencia a taxa de oclusão de veias safenas tratadas por endolaser. Objetivos Analisar a taxa de oclusão dos segmentos venosos tratados com endolaser e correlacionar com o Venous Clinical Severity Score (VCSS) e a classificação Clínica-Etiológica-Anatômica-Patológica (CEAP) dos pacientes. Métodos Análise retrospectiva de coorte de pacientes operados com endolaser 1.470 nm entre novembro/2012 a março/2020. Foram realizadas estatística descritiva e curva de sobrevida de Kaplan-Meier com regressão de Cox para grupos de VCSS e CEAP. Resultados Foram analisados 170 pacientes e 180 segmentos venosos; a idade média foi de 44,3 ± 9,2, sendo a maioria do sexo feminino (71%). A densidade de energia média utilizada na veia safena magna foi 49,2 ± 8,3 J/cm. As principais complicações foram dor no trajeto da safena (12,2%) e parestesias após 6 meses (17,2%). Não houve diferença na taxa de oclusão venosa entre grupos com VCSS ≤ 7 e VCSS > 7 (p = 0,067). O grupo de pacientes com CEAP agrupada C4-C5-C6 teve taxa de oclusão menor em relação ao grupo C2-C3 [hazard ratio (HR) = 3,22; intervalo de confiança (IC) 1,85, 5,61; p = 0,001]. Conclusões As taxas de oclusão de segmentos venosos tratados com endolaser foram menores na presença de classificações CEAP avançadas. Nesses pacientes, provavelmente deve-se despender mais energia para o tratamento eficaz das safenas.

Abstract Background Patients with advanced chronic venous disease are more likely to need additional procedures for relapsed varicose veins. It has not yet been established whether severity of venous insufficiency is a factor that influences the occlusion rate of saphenous veins treated with endolasers. Objectives To analyze occlusion rate of venous segments treated with endolaser and correlate it with patients’ Venous Clinical Severity Score (VCSS) and Clinical-Etiological-Anatomical-Pathological (CEAP) classification. Methods Retrospective analysis of a cohort of patients operated using a 1,470 nm endolaser from November 2012 to March 2020. Descriptive statistics were calculated and Kaplan-Meier survival curves were plotted with Cox regression for groups stratified by VCSS and CEAP. Results A total of 180 venous segments were analyzed in 170 patients. Mean age was 44.3 ± 9.2 and the majority of patients were female (71%). Mean energy density used in the great saphenous vein was 49.2 ± 8.3 J/cm. The most common complications were pain along the course of the saphenous vein (12.2%) and paresthesias at 6 months (17.2%). There was no difference in venous occlusion rate between groups with VCSS ≤ 7 and VCSS > 7 (p = 0.067). A group of patients classified as CEAP classes C4, C5, or C6 had a lower occlusion rate than a group at classes C2 or C3 (hazard ratio [HR] = 3.22; confidence interval [CI] 1.85, 5.61; p = 0.001]. Conclusions The occlusion rates of venous segments treated with endolaser were lower in patients with higher CEAP classes. It is probably necessary to use more energy in these patients to achieve effective treatment of saphenous veins.

ABSTRACT: Seedling production is an important step in the lettuce production system. However, there is a tendency to apply excessive irrigation at this stage. The aim of this study was to test the use of the Simplified Irrigation Controller (SIC) under two conditions: first, with the sensor installed in the substrate (measuring the soil water tension) and second, in the atmosphere (“atmospheric” - responding to vapor demand in the atmosphere) to control the irrigation of lettuce seedlings. The performance of the SIC was evaluated by monitoring plant traits. The lettuce seeds of the Regina cultivar were sown in styrofoam trays with commercial organic substrate. Both experiments were conducted under greenhouse conditions and evaluated under different SIC activation tensions. Shoot fresh weight and dry weight, height, number of leaves, leaf length, leaf area, water use efficiency (WUE) (ratio between the dry mass of plant produced by the volume of water applied), chlorophyll content, stomatal conductance and chlorophyll a fluorescence were assessed. In the experiment with the substrate sensor, the tension of 11.5 kPa caused death in 94 % of the seedlings and was disregarded in the statistical analysis. All biometric and physiological traits evaluated decreased as the SIC tensions increased. Thus, tensions of 4.0 (substrate sensor) and 3.5 kPa (atmospheric sensor) showed greater potential for producing vigorous seedlings, with WUE average values of 1.86 and 1.37 g L−1, respectively. Cultivation of lettuce seedlings proved viable under both conditions when the SIC was used, with the emergence of a number of practical advantages of the atmospheric sensor over the substrate one.

RESUMO: Objetivando conhecer a situação da tuberculose ovina no Maranhão, avaliaram-se 343 ovinos da região sudoeste do estado, 247 fêmeas e 96 machos, com idade acima de 6 meses, por meio do teste cervical comparativo (TCC), com inoculação de tuberculinas na região cervical direita. Cranialmente, injetou-se derivado proteico purificado (PPD) aviário; e caudalmente, PPD bovino, em doses individuais de 0,1 mL. Todos os animais apresentaram resultado negativo para tuberculose, entretanto, 65 ovinos apresentaram reação à tuberculina bovina superior à aviária. Para investigar a possibilidade de baixa sensibilização ou anergia em animais com tuberculose avançada, foi necropsiado um ovino caquético, idade acima de quatro anos, com resultado negativo ao TCC, porém, com reação à tuberculina aviária e linfonodos aumentados com consistência endurecida. Os resultados indicaram infecções por C. pseudotuberculosis, Actinomyces pyogenes, Staphylococcus aureus e Mycobacterium sp. A cultura e o isolamento resultaram em Pseudomonas aeruginosas e Bacillus sp. Não foram visualizadas estruturas bacterianas compatíveis com bacilo álcool ácido resistente (BAAR). Os resultados confirmam ausência de animais reagentes ao M. bovis, pressupondo inexistência da tuberculose em ovinos na região estudada.

ABSTRACT: In order to know the situation of ovine tuberculosis in Maranhão, Brazil, we evaluated 343 sheep in the southwest region of the state, of both sexes (247 females and 96 males), aged over six months, through the comparative cervical test (TCC), with tuberculin inoculation in the right cervical region. Cranially, avian purified protein derivate (PPD) was injected; and caudally, beef PPD was injected, in individual doses of 0.1 mL. All animals were negative for tuberculosis; however, 65 sheep had higher reactions to bovine tuberculin than to the avian one. To investigate the possibility of low awareness or anergy in animals with advanced tuberculosis, one cachectic sheep was necropsied, aged four years, with negative results for TCC, but with reaction to avian tuberculin and enlarged hardened lymph nodes. The results indicated C. pseudotuberculosis, Actinomyces pyogenes, Staphylococcus aureus and Mycobacterium sp infections. Culture and isolation resulted in Pseudomonas aeruginosa and Bacillus sp. No bacterial structures compatible with acid-fast bacteria were found. The results confirmed the absence of animals reactive to M. bovis, assuming no tuberculosis in sheep in the study area.

Objective This study aims to estimate the prevalence of thyroid diseases and anti-TPO status. We searched for an association among presence of immune reconstitution and use of stavudine, didanosine and protease inhibitors with thyroid diseases. Materials and methods A cross-sectional study was performed to analyze the records of 117 HIV-infected patients who had their CD4+ cell count, viral load, anti-TPO, TSH and free T4 levels collected on the same day. Immune reconstitution was considered in those whose T CD4+ count was below 200 cells/mm3, but these values increased above 200 cells/mm3 after the use of antiretrovirals. The odds ratio obtained by a 2x2 contingency table and a chi-square test were used to measure the association between categorical variables. Results The prevalence of thyroid disease was 34.18%; of these, 4.34% were positive for anti-TPO. There was an association of risk between stavudine use and subclinical hypothyroidism (OR = 4.19, 95% CI: 1.29 to 13.59, X2 = 6.37, p = 0.01). Immune reconstitution achieved protection associated with thyroid disease that was near statistical significance OR = 0.45, 95% CI: 0.19 to 1.04, X2 = 3.55, p = 0.059. Conclusion The prevalence of thyroid disease in the sample studied was higher than what had been found in the literature, with a low positive anti-TPO frequency. The historical use of stavudine has an association of risk for the presence of subclinical hypothyroidism, and immune reconstitution has trends towards protection for the presence of thyroid diseases.

A trombectomia mecânica tem a vantagem de levar à rápida remoção dos trombos. Permite a desobstrução venosa e a redução do tempo de infusão de trombolíticos. A aspiração dos trombos pode levar a complicações, principalmente embolia pulmonar e hemólise. Algo que não está definido é a validade do uso de filtros de veia cava durante a trombectomia, com o objetivo de evitar a TEP maciça. Os autores relatam um caso de embolia pulmonar maciça associada a AVC isquêmico, em uma paciente que apresentava forame oval patente. Não havia o diagnóstico prévio da PFO. A paciente evoluiu com insuficiência respiratória e déficit neurológico logo após a trombectomia. Neste caso, questiona-se o valor da trombectomia para o tratamento da trombose venosa proximal, devido aos riscos deste procedimento. Os autores discutem sobre a necessidade de filtro de veia cava e sobre a pesquisa de forame oval nos pacientes que serão submetidos à trombectomia.

Mechanical thrombectomy offers the advantage of rapid removal of venous thrombi. It allows venous obstructions to be removed and requires shorter duration of infusion of thrombolytic agents. However, aspiration of thrombi can lead to complications, particularly pulmonary embolism and hemolysis. The validity of using vena cava filters during thrombectomy in order to avoid embolism has not yet been established. The authors report a case of massive pulmonary embolism associated with ischemic stroke in a patient with a hitherto undiagnosed patent foramen ovale. The patient developed respiratory failure and neurological deficit after thrombectomy. This case raise questions about the value of the thrombectomy for the treatment of proximal vein thrombosis due to the risks of this procedure. The authors also discuss the need for vena cava filters and ruling out a patent foramen ovale in patients undergoing thrombectomy.

INTRODUÇÃO: O pseudoaneurisma femoral é complicação descrita em até 8% dos procedimentos percutâneos. Dentre os tratamentos, a injeção de trombina guiada por ultrassom tem alta taxa de sucesso e boa tolerância pelos pacientes. O uso da trombina associada ao fibrinogênio, chamado selante de fibrina, forma um coágulo estável que pode ser usado para o tratamento do pseudoaneurisma, principalmente aqueles de anatomia complexa e maiores. OBJETIVO: Comparar os resultados do tratamento do pseudoaneurisma femoral em dois grupos: Grupo T, tratado com trombina isoladamente, e Grupo T+F, tratado com selante de fibrina (trombina+fibrinogênio). MÉTODO: Análise retrospectiva dos casos de pseudoaneurisma femoral tratados entre janeiro/2005 e dezembro/2012. RESULTADOS: Foram tratados 28 pacientes, 21 com trombina isolada e sete com selante de fibrina. Houve sucesso no tratamento de todos os pacientes do grupo T e somente em quatro casos do grupo T+F (57,1% no Grupo T+F, p<0,01). Os três casos de insucesso no grupo T+F necessitaram cirurgia, sendo que, em um deles, a causa foi embolização para a bifurcação femoral. Os pseudoaneurismas tratados com selante de fibrina apresentaram maior tamanho (25 cm3 no Grupo T e 57,7 cm3 no Grupo T+F, p=0,02) e houve necessidade de maior volume de trombina (0,5 mL no Grupo T e 1,0 mL no Grupo T+F, p<0,01). Houve uma complicação no Grupo T e duas no Grupo T+F (p<0,01). CONCLUSÃO: Apesar do número reduzido de casos, o tratamento com trombina isolada foi superior ao selante de fibrina, levando a poucas complicações e à maior eficácia para resolução do pseudoaneurisma.

INTRODUCTION: Femoral pseudoaneurysms are a complication that occurs in connection with up to 8% of percutaneous procedures. Of the available treatments, ultrasound guided thrombin injection has a high success rate and is well-tolerated by patients. The combination of thrombin and fibrinogen known as fibrin sealant forms a stable clot and can be used to treat pseudoaneurysms, particularly those with complex anatomy and larger size. OBJECTIVE: To compare the results of treating femoral pseudoaneurysm in two ways: Group T was treated with thrombin alone and Group T+F was treated with fibrin sealant (thrombin+fibrinogen). METHODS: A retrospective analysis was conducted of femoral pseudoaneurysm cases treated between January 2005 and December 2012. RESULTS: Twenty-eight patients were treated, 21 with thrombin alone and seven with fibrin sealant. All patients in group T were treated successfully, but only four patients in group T+F were treated successfully (57.1% success rate in Group T+F, p<0.01). The three cases of failure in group T+F needed surgery and in one of these cases the complication was embolization to the femoral bifurcation. The pseudoaneurysms that were treated with fibrin sealant were larger (25 cm3 in Group T and 57.7 cm3 in Group T+F, p=0.02) and required larger volumes of thrombin (0.5 mL in Group T and 1.0 mL in Group T+F, p<0.01). There was one complication in Group T and two complications in Group T+F (p<0.01). CONCLUSIONS: Irrespective of the small number of cases reviewed, treatment with thrombin alone was superior to treating with fibrin sealant, since it caused few complications and was more effective at correcting pseudoaneurysms.

A trombose venosa profunda é uma entidade clínica potencialmente grave, responsável por elevada morbimortalidade. A ecografia vascular representa o método propedêutico de escolha no diagnóstico e acompanhamento dos pacientes com essa doença. Entretanto, várias questões permanecem controversas, tais como a abordagem inicial do paciente com suspeita de trombose venosa profunda, os tipos de protocolo a serem usados, o tempo para a realização do exame e a trombose no plexo de panturrilha. O objetivo dessa revisão é discutir esses assuntos à luz dos conhecimentos atuais.

Deep vein thrombosis is a potentially serious clinical entity, responsible for high morbidity and mortality. The vascular ultrasound is the diagnostic methods of choice in the diagnosis and monitoring of patients with this disease. However, several issues remain controversial, such as the initial approach of patients with suspected deep vein thrombosis, protocols to be used, the time for the exam and thrombosis in the calf plexus. The objective of this review is to discuss these issues in light of current knowledge.

Em 2004, segundo Costa-Santos e cols., p.W406R e p.R362C correspondiam a 50% e 32% dos alelos mutantes do gene CYP17A1, respectivamente, em 24 pacientes de 19 famílias brasileiras com deficiência da 17α-hidroxilase. Apresentamos os dados clνnicos e moleculares de seis pacientes de três famílias consanguíneas brasileiras com deficiência da 17α-hidroxilase. Todas as pacientes apresentavam hipogonadismo, amenorreia e hipertensão ao diagnóstico. Duas irmãs tinham cariótipo 46,XY, ambas com gônadas palpáveis na região inguinal. Todas tinham hipogonadismo hipergonadotrófico, com nível aumentado de ACTH (> 104 ng/mL), atividade de renina plasmática suprimida, baixos níveis de potássio (< 2,8 mEq/L) e progesterona aumentada (> 4,4 ng/mL). Três delas, incluindo duas irmãs, apresentaram homozigose para a mutação p.W406R e as outras três (duas irmãs e uma prima) foram homozigotas para a mutação p.R362C. A recorrência das mutações p.W406R e p.R362C no gene CYP17A1 aqui relatada em famílias adicionais confirma que essas são as mais frequentes causadoras do fenótipo completo da deficiência combinada de 17α-hidroxilase/17,20-liase em pacientes brasileiros.

In 2004, Costa-Santos and cols. reported 24 patients from 19 Brazilian families with 17α-hydroxylase deficiency and showed that p.W406R and p.R362C corresponded to 50% and 32% of CYP17A1 mutant alleles, respectively. The present report describes clinical and molecular data of six patients from three inbred Brazilian families with 17α-hydroxlyse deficiency. All patients had hypogonadism, amenorrhea and hypertension at diagnosis. Two sisters were found to be 46,XY with both gonads palpable in the inguinal region. All patients presented hypergonadotrophic hypogonadism, with high levels of ACTH (> 104 ng/mL), suppressed plasmatic renin activity, low levels of potassium (< 2.8 mEq/L) and elevated progesterone levels (> 4.4 ng/mL). Three of them, including two sisters, were homozygous for p.W406R mutation and the other three (two sisters and one cousin) were homozygous for p.R362C. The finding of p.W406R and p.R362C in the CYP17A1 gene here reported in additional families, confirms them as the most frequent mutations causing complete combined 17α-hydroxylase/17,20-lyase deficiency in Brazilian patients.
