ABSTRACT

Abstract Introduction: Members of the Herpesviridae family have been described in patients with systemic lupus erythematous (SLE), but the clinical impact on renal function is not well known. Methods: HSV1, HSV2, VZV, EBV, CMV, HHV-6, HHV-7, and HHV-8 were evaluated by molecular biology on admission in blood samples from 40 consecutive SLE patients hospitalized for lupus activity. Results: Patients were 90.0% female, 77.5% non-white, with average age of 32.7 ± 13.6 years. We found positivity for EBV (65.0%), CMV (30.0%), HSV-1 (30.0%), HHV-6 (12.5%), and HHV-7 (7.5%). For all viruses, age, SLEDAI, hematological tests, ferritin, LDH, C-reactive protein, and erythrocyte sedimentation rate (ESR) were not significant. However, EBV positivity was a significant factor for higher serum creatinine (3.0 ± 2.8 vs. 0.9 ± 0.8; P = 0.001) and urea (86 ± 51 vs. 50 ± 46; P = 0.03). Moreover, positive cases for EBV only or with combined co-infections (66.7%-CMV; 58.3%-HSV-1) or negative for EBV only were evaluated by Kruskal-Wallis test again showed statistical significance for serum creatinine and urea (both P ≤ 0.01), with posttest also showing statistical differences for renal dysfunction and EBV presence (alone or in combined co-infections). The presence of EBV viral load was also significant for nephrotic-range proteinuria, renal flare, and the need for hemodialysis. Conclusion: Members of the Herpeviridae family (mainly EBV, HSV-1 and CMV) are common on hospital admission of SLE patients, reaching 65% for EBV, which seems to be associated with renal dysfunction and could reflect a previous association or overlapping disease, which is not well understood.


Resumo Introdução: Membros da família Herpesviridae tem sido descritos em pacientes com lúpus eritematoso sistêmico (LES), mas o impacto clínico na função renal não é bem conhecido. Métodos: Avaliou-se HSV1, HSV2, VZV, EBV, CMV, HHV-6, HHV-7, HHV-8 por biologia molecular na admissão em amostras sanguíneas de 40 pacientes com LES consecutivos hospitalizados por atividade lúpica. Resultados: Pacientes 90,0% mulheres, 77,5% não brancos, idade média 32,7 ± 13,6 anos. Encontramos positividade para EBV (65,0%), CMV (30,0%), HSV-1 (30,0%), HHV-6 (12,5%), HHV-7 (7,5%). Para todos os vírus, idade, SLEDAI, exames hematológicos, ferritina, LDH, proteína C reativa, velocidade de hemossedimentação não foram significativos. Entretanto, positividade para EBV foi estatisticamente significativo para creatinina (3,0 ± 2,8 vs. 0,9 ± 0,8; P = 0,001) e ureia (86 ± 51 vs. 50 ± 46; P = 0,03) séricas mais elevadas. Ademais, casos positivos para EBV isolado ou com coinfecções combinadas (66,7%-CMV; 58,3%-HSV-1) ou negativos apenas para EBV foram avaliados pelo teste Kruskal-Wallis e novamente mostraram significância estatística para creatinina e ureia séricas (ambas P ≤ 0,01), com pós-teste mostrando também diferenças estatísticas para disfunção renal e presença de EBV (sozinho ou em coinfecções combinadas). A presença de carga viral do EBV também foi significativa para proteinúria de faixa nefrótica, inflamação aguda, necessidade de hemodiálise. Conclusão: Membros da família Herpeviridae (principalmente EBV, HSV-1, CMV) são comuns na admissão de pacientes com LES, chegando a 65% para EBV, que parece associar-se à disfunção renal podendo refletir associação prévia ou doença sobreposta, o que não é bem compreendido.

ABSTRACT

Introduction : Multi slice Computed Tomography Pulmonary Angiography (CTPA) in dynamic pitch (Volume Helical Shuttle-VHS) mode is an evolving method to visualize pulmonary arteries including the peripheral pulmonary vasculature. The purpose of this study is to evaluate CT Pulmonary Angiography in dynamic pitch mode (Volume Helical Shuttle) for pulmonary embolism in comparison with standard pitch mode. Methods : We have done a multicentric analytical comparison study with study group involving patients undergone CTPA in dynamic pitch mode-Volume Helical Shuttle (VHS) and comparison group involving patients undergone CTPA in standard pitch mode. Results : Optimal contrast enhancement phase of the pulmonary artery in the study group in Phase I to III were 22.6%, 43.4% and 34%. The best phases were the last two phases in our study. Study Group main pulmonary artery mean signal intensity is 423.83±75.94 HU and comparison groups mean signal intensity is 361.74±98.28HU (P value = 0.039). The percentages of analyzable segmental arteries were 91.6% in study group and 87.3% in comparison group (P value-0.008). The percentages of analyzable sub segmental arteries were 89.5% in study group and 84% in comparison group (P value-0.004). The study group shows less percentage of motion artefacts and higher image quality than the comparison group, however it was not statistically significant (P value >0.05). Conclusions : Multislice CTPA in dynamic pitch mode using Volume Helical Shuttle (VHS) technology increase the ability to obtain the Optimal contrast enhancement in pulmonary arteries, improves the overall image quality, obviate the need for breath holding.

ABSTRACT

Abstract: objective: to detect the presence of infection by EBV (Epstein-Barr Virus), CMV (Cytomegalovirus) and HSV-1 (Herpes Simplex Virus type 1) in subgingival samples from HIV- positive patients under HAART (High Activity Antiretroviral Therapy), HIV- positive patients without HAART, HIV-negative patients with chronic periodontitis and healthy controls. Methodology: Crevicular fluid samples of 11 HIV+ patients on therapy were evaluated, 6 without antiretroviral therapy, 7 HIV- negative subjects with chronic periodontitis and 7 periodontally-healthy controls. PI (Plaque index), GI (Gingival Index), PD (probing depth) and CAL (Clinical Attachment Loss) were registered at six sites per each tooth in all teeth and subgingival plaque samples of a tooth were collected per quadrant. Nested PCR was used to detect EBV and endpoint PCR to detect infection by CMV and HSV-1. Results: Clinical parameters showed statistically significant differences between HIV-positive patients and subjects with chronic periodontitis compared with the control group (p<0.05). DNA of EBV was detected mainly in HIV-positive patients under HAART, 91 percent (10/11). DNA of CMV was detected mainly in patients without HAART, 67 percent (4/6), while HSV-1 was observed in 27 percent (3/11) of patients under HAART. In the control group no virus was detected. Coinfection was observed in 50 percent of HIV patients without HAART, 36 percent of HIV patients with HAART and 14 percent of HIV-negative with chronic periodontitis. Conclusion: Viral infection was prevalent in HIV patients under HAART and EBV was the primary viral infection detected in HIV-positive patients with chronic periodontitis.

ABSTRACT

La infección por el HIV-1 cursa con enfermedades oportunistas asociadas. En referencia a los virus herpes, la asociación más conocida es con el HVS-2. La coinfección HIV-1, HVS-1 y P. jiroveci constituye un cuadro clínico de alta morbilidad y baja frecuencia. Caso clínico: una paciente de 17 años de edad fue derivada a la consulta con sintomatología compatible con gingivoestomatitis herpética recurrente resistente a la terapia con aciclovir p.o. 200 mg cada 5 hs y tratada con amoxicilina-clavulánico p.o. (875 mg-125 mg) cada 12 hs por 20 días. Al ingreso presentaba adenitis cervical, odinofagia, disnea, fiebre (38.2ºC), pulso: 120/min, presión arterial: 120/75 mm Hg, frecuencia respiratoria: 24/min y deterioro generalizado. Se solicitó hacer la serología para el HIV y estudio RX de tórax. La serología para HIV-1 resultó positiva y los valores de CD4+ y carga viral fueron 320/mm3 y 25.000 copias/ml, respetivamente. El estudio RX de tórax reveló neumonía por P. jiroveci que se confirmó posteriormente por fibrobroncoscopía. Se realizó el tratamiento farmacológico de la infección herpética con foscarnet (i.v) 60mg /kg cada 12 hs. durante 3 días, mientras que la neumonía se trató con trimetropima 160 mg y sulfametoxazol p.o. 800 mg cada 6 horas durante 14 días. La remisión de la sintomatología bucal se oservó a los 15 días postratamiento. Conclusión: la población femenina adolescente evidencia una mayor vulnerabilidad biológica y social en relación a la transmisión del HIV. El odontólogo responsable deberá calibrarse en el reconocimiento y diagnóstico precoz de las manifestaciones bucales de dicha infección viral. Ante la presencia de cepas de HVS-1 aresistentes deberá contemplarse la posibilidad de otras infecciones oportunistas simultáneas

ABSTRACT

The VHS and CTR were assessed using computerized thoracic radiographs of ten clinically healthy tufted capuchin monkeys (five males and five females) from the Wild Animal Screening Center in São Luís (Centro de Triagem de Animais Silvestres de São Luís-MA-CETAS). Radiographs were taken in laterolateral and dorsoventral projections to calculate the cardiothoracic ratio (VHS) and vertebral heart size (CTR). The VHS showed mean values of 9.34±0.32v (males) and 9.16±0.34v (females) and there was no statistical difference between males and females (p>0.05). The CTR showed mean values of 0.55±0.04 (males) and 0.52±0.03 (females) and there was no statistical difference between the sexes (p>0.05). There was positive correlation between VHS and CTR (r=0.78). The thoracic and heart diameters showed mean values of 5.70±0.48cm and 2.16±0.40cm in the males, respectively. In the females they measured 5.32±0.39cm and 2.94±0.32cm. There was no statistical difference between the sexes. Our results show that the high correlation found between VHS and CTR permitted the verification with similar clinical precision between the two methods to estimate alterations in the heart silhouette by radiographic examination of tufted capuchin, making it an easy technique to apply that can be considered in the investigation of heart problems for this wild species...


Para a avaliação do VHS e ICT foram utilizadas radiografias torácicas computadorizadas de 10 macacos-prego (05 machos e 05 fêmeas) clinicamente saudáveis, oriundos do Centro de Triagem de Animais Silvestres de São Luís-MA-CETAS. Foram tomadas radiografias em projeções laterolaterais e dorsoventrais, para cálculo do Vertebral Heart Scale (VHS) e Índice Cardiotorácico (ICT). O VHS evidenciou valores médios de 9,34±0,32v (machos) e 9,16±0,34v (fêmeas), não ocorrendo diferença estatística entre machos e fêmeas (p>0,05). O ICT evidenciou valores médios de 0,55±0,04 (machos) e de 0,52±0,03 (fêmeas), não sendo verificada diferença estatística entre sexos (p>0,05). Verificou-se correlação positiva entre VHS e ICT (r=0,78). Os diâmetros torácico e cardíaco demonstraram valores médios de 5,70±0,48cm e 3,16±0,40cm nos machos, respectivamente. Nas fêmeas mediram 5,32±0,39cm e 2,94±0,32cm. Não houve diferença estatística entre os sexos (p>0,05). Os nossos resultados demonstraram que a alta correlação encontrada entre o VHS e o ICT permitiu verificar precisão clínica semelhante entre os dois métodos, para estimar alterações da silhueta cardíaca ao exame radiográfico de macacos-prego, constituindo-se como uma técnica de fácil aplicação, poddevendo ser considerada na investigação de problemas cardíacos para esta espécie silvestre...

ABSTRACT

O MicroSed-System® (Vital diagnóstico, Itália) é um analisador automático para a determinação da velocidade de hemossedimentação (VHS) que oferece coleta de sangue avácuo em tubos fechados de vidro, com leitura automatizada de ponto final, após 30 minutos. A dificuldade para aquisição dos tubos padronizados para o equipamento tem forçado muitos laboratórios a confeccionar seus próprios tubos, durante suas rotinaslaboratoriais. O objetivo deste trabalho foi avaliar a utilização de tubos confeccionados no laboratório para o equipamento MicroSed-System®, com o método de Westergren preconizado pelo Conselho Internacional de Padronização em Hematologia-ICSH (1988). Paralelamente, foi realizada uma correlação dos valores da VHS de um grupo de pacientes com valores quantificados da proteína C-reativa (PCR). Foram coletadas 139 amostrasde pacientes ambulatoriais e internados no Hospital de Guarnição de Santa Maria (HGuSM, Brasil, RS), de ambos os sexos, com idade variando entre 18 e 78 anos. Cada amostra ensaiada para VHS foi analisada no equipamento MicroSed-System® e pelométodo de Westergren, após diluição com uma solução de citrato de sódio 0,129 M. Os resultados dos valores obtidos para a VHS, no equipamento MicroSed-System® e pelo método de Westergren, indicaram boa correlação entre os métodos com coeficiente decorrelação, segundo Pearson, igual a 0,984 (p<0,001). Para a comparação dos valores da VHS e PCR, foi observada uma menor correlação, sendo o coeficiente igual a 0,791(p<0,0001), segundo Pearson. Assim, pode-se concluir que os tubos para MicroSed-System® confeccionados no laboratório podem ser utilizados como um método alternativo na determinação da VHS. Comparando os resultados da PCR e VHS foi observadamenor correlação.

ABSTRACT

The agouti is a species intensively hunted throughout the Amazon and the semi-arid regions of northeastern Brazil. Considering the current trend in conservation management of wild species, the aim of this study was to determine the morphometric reference to the heart of agouti raised in captivity, based on thoracic and cardiac measurements in these animals. Thirty adult agoutis, 1 to 3 years of age, without clinical signs of cardiac disease were selected. The animals were physically restrained and radiographies in laterolateral (LL) and ventrodorsal (VD) recumbence were produced. The following measures were taken: the apicobasilar length of the heart (at the most cranial height of the Carina region to the heart apex) (AB), maximum width of the heart perpendicular to AB (CD), heart inclination angle (AIC), trachea inclination angle (AIT), distance from the right heart wall (DPTd), distance from the left heart wall (DPTe) and vertical depth of the thorax, and the ventral face of the vertebral column to the dorsal border of the sternum at the level of the trachea bifurcation (H). The ratios between AB/CD, AB/H and CD/H were also analyzed. To calculate the vertebral heart scale (VHS), the AB and CD measurements were laid over the thoracic vertebra starting at T4. Radiographic evaluation showed values consistent with those reported in small animals and some wild and exotic species. The main biometric values in the chest cavity and heart of agouti are arranged as follows: (1) The ratios between AB/H ratio and CD/H were not sensitive for identifying heart increases (p>0.05), while the ratio AB/CD was more sensitive in this identification (p<0.05); (2) AIC: 21.2±6.4º (mean between male and famale); (3) AIT for males and females: 9.93±3.23° and 8.4±3.94°; (4) DPTd and DPTe for males: 0.97±0.40cm and 0.7±0.30cm; (5) DPTd and DPTe for females: 1.12±0.42cm and 01.02±0.43cm; (6) VHS for males and females: 7.75±0.48v e 7.61±0.34v; (7) The caudal vena cava (CVC) was visualized dorsal-cranially and located right of the midline. The data obtained allowed the acquisition of the first reference values for biometry of the heart of agoutis, contributing to better understanding of cardiac morphology and identification of cardiomyopathy in these animals.


A cutia é uma espécie intensamente caçada em toda a Amazônia e nas regiões semi-áridas do Nordeste do Brasil. Considerando a tendência atual em gestão de conservação das espécies selvagens, o objetivo deste estudo foi determinar referências morfométricas para o coração de cutia criadas em cativeiro, com base em medições torácicas e cardíacas desses animais. Foram selecionados 30 cutias adultas, sem sinais clínicos de doença cardíaca, com idade entre 1 a 3 anos. Os animais foram contidos fisicamente e realizadas projeções radiográficas laterolaterais e (LL) e ventrodorsais (VD). As seguintes medidas foram tomadas: O comprimento apicobasilar do coração (na altura mais cranial da região carina até o ápice do coração) (AB); a largura máxima coração perpendicular a AB (CD); o ângulo de inclinação do cardíaca (AIC); ângulo de inclinação da traquéia (AIT); a distância a partir da parede direita do coração (DPTd); a distância a partir da parede esquerda do coração (DPTe) e profundidade vertical do tórax, da face ventral da coluna vertebral até à borda dorsal do esterno, no nível da bifurcação da traqueia (H). As relações entre AB/CD, AB/H e CD/H também foram analisadas. Para calcular o "vertebral heart scale" (VHS), as medidas AB e CD foram colocadas sob as vértebras torácicas a partir de T4. A avaliação radiográfica demonstrou valores consistentes com aqueles relatados em pequenos animais e algumas espécies selvagens e exóticos. Os principais valores biométricos mensurados na cavidade torácica e cardíaca da cutia, estão dispostas da seguinte forma: (1) As relações entre AB/H e CD/H não foram sensíveis para identificar aumento do coração (p> 0,05), enquanto a proporção AB/CD foi mais sensível nesta identificação (p <0,05); (2) AIC: 21,2 ± 6.4º (média entre machos e fêmeas); (3) AIT para machos e fêmeas: 9.93 ± 3.23° and 8.4±3.94°; (4) DPTd e DPTe para os machos: 0,97 ± 0,40 cm e 0,7 ± 0,30, (5) DPTd e DPTe para as fêmeas: 1,12 ± 0,42 e 01,02 ± 0,43; (6) VHS para machos e fêmeas: 7.75±0.48v e 7.61±0.34v; (7) A veia cava caudal (CVC) foi visualizada dorso-cranialmente e localizada à direita da linha média. Os dados obtidos permitiram a obtenção dos primeiros valores de referência para a biometria do coração de cutias, contribuindo para uma maior compreensão da morfologia cardíaca e identificação de cardiomiopatia nestes animais.

ABSTRACT

Determinou-se valor médio do vertebral heart size (VHS) em cães da raça Yorkshire Terrier. Foram selecionados 30 cães clinicamente normais, com média de peso de 2,42±0,64kg e idades entre um e seis anos. Os animais foram submetidos ao exame radiográfico do tórax nas projeções lateral direita, ventrodorsal e dorsoventral. Foram feitas mensurações para avaliação cardíaca e da profundidade e largura torácicas. O valor médio de VHS foi de 9,9±0,6 vértebras na projeção lateral, 10,1±0,6 vértebras na projeção ventrodorsal e 10,0±0,6 vértebras na projeção dorsoventral. Não houve diferença entre esses valores. Cinco animais (16,7 por cento) apresentaram VHS acima de 10,5 vértebras, valor sugerido como limite superior para a maioria das raças, em projeção lateral. Os valores de VHS correlacionaram-se com peso corporal nas projeções lateral e ventrodorsal. A razão profundidade:largura torácica apresentou valor médio de 0,75±0,06. Não foi observada correlação entre a qualidade do tórax e o VHS.


The mean vertebral heart size (VHS) was established for Yorkshire Terrier dogs. Thirty clinically normal dogs with mean weight of 2.42±0.64kg and ages varying from one to six years of age, were studied. The animals were submitted to right lateral, ventrodorsal and dorsoventral thoracic radiographs. The Buchanan e Bücheler method was applied to the cardiac silhouette and thoracic depth and width. The VHS was 9.9±0.6 vertebrae on lateral, 10.1±0.6 on ventrodorsal and 10.0±0.6 on dorsoventral radiographs. There was no difference among these values. Five animals (16.7 percent) presented VHS values exceeding 10.5, the value suggested as upper limit for most breeds in lateral view. However, 95 percent of the animals in this study provide VHS values below the upper limit, and this should be equal to 11 vertebrae. The VHS values had significant correlation with body weight on lateral and VD radiographs. The mean depth:width ratio was 0.75±0.06. There was no correlation among VHS and depth:width ratios.

ABSTRACT

Diversos virus afectan el sistema nervioso central (SNC) ocasionando encefalitis, principalmente en la edad pediátrica. Determinar la implicación de agentes virales en infecciones del sistema nervioso central (SNC) en niños del estado Zulia, Venezuela durante el año 2007. Se recolectaron 109 muestras de líquido cefalorraquídeo(LCR) y suero, provenientes de pacientes entre 1 día de nacido a 14 años, que presentaron sintomatología clínica sugestiva de afectación del SNC y cuyo estudio bacteriológico convencional de LCR resultó negativo. Se determinó la relación albúmina LCR/suero a fin de descartar contaminación, resultando 24 pares óptimos para la determinación por la técnica de ELISA de anticuerpos IgM específicos para los virus Herpes Simple (VHS), Epstein Barr (VEB), Dengue, Rubéola, Sarampión y Encefalitis Equina Venezolana (EEV). De los 24 casos analizados, 15 (62,5%) resultaron positivos. Los agentes causantes de encefalitis fueron: 11 casos de Dengue (45,8%) (p<0,05), 3 de VHS (12,5%) y un caso de VEB (4,2%). No se detectaron casos de Rubéola, Sarampión, ni EEV. La pleocitocis con predominio de linfocitos fue el hallazgo más frecuente en los casos con encefalitis viral (EV) confirmada, sin diferencias significativas al relacionarlo con el agente viral infectante. Se evidencia que una proporción significativa de los niños con encefalitis es debida a agentes virales y se destaca un incremento en los casos de dengue con afectación del SNC en la región


Various viruses affect the central nervous system (CNS) causing encephalitis, mainly in pediatric patients. To determine the involvement of viral agents for central nervous system (CNS) infections in children in the State of Zulia, Venezuela during the year 2007. 109 samples of cerebrospinal fluid (CSF) and serum were collected from patients between 1 day and 14 years of age, who presented clinical symptoms suggestive of CNS involvement and whose conventional CSF bacteriological study proved negative. The CSF Albumin /serum relation ship was determined in order to rule out contamination, resulting in 24 optimal pairs for determining the IgM and IgG antibodies specific for herpes simplex virus (HSV), Epstein Barr (EBV), Dengue fever, rubella, measles and Venezuelan Equine Encephalitis (VEE) using the ELISA technique. Of the 24 cases examined, 15 (62.5%) were positive. The causative agents for encephalitis were 11 cases of Dengue (45.8%) (p<0.05), 3 VHS (12.5%) and 1 case of EBV (4.2%). There were no cases of rubella, measles or VEE. Pleocytosis with lymphocyte predominance was the most common finding in cases with confirmed viral encephalitis (VE), without significant differences related to the infecting viral agent. Results show that a significant proportion of encephalitis in children is due to viral agents, highlighting an increase in dengue cases with CNS affection in the region
