RESUMO
OBJECTIVES: To evaluate the presence of ET-1 in patients with scleroderma and its correlation with the level of disease activity; to verify if the levels of endothelin are associated with the clinical profile and autoantibodies of scleroderma, and even if there is an association with microvascular injury detected by nailfold capillaroscopy. METHODS: A total of 74 patients, 37 patients with scleroderma, the remaining being controls, were subjected to measurement of ET-1 by ELISA. Patients with scleroderma were evaluated through a questionnaire about characteristics of the disease and determination of autoantibodies. Disease severity was defined by the criteria of Medsger and microvascular disease was accessed through nailfold capillaroscopy. RESULTS: Of the 37 patients with scleroderma, three (8.1%) were men and 34 (91.89%) women, with a mean age of 48.97 ± 13.36 years and mean disease duration of 42.54 ± 13, 35. The amounts of ET-1 in the controls was 0.41 to 5.65 pg / ml (median of 2.26 pg / ml) and, in the scleroderma group, from 0.41 to 8.82 pg / ml (median, 0.41 pg / ml), with p = 0.0007. There was no correlation with disease duration, patient age and the degree of skin involvement. No correlation was found between serum levels of ET-1 and disease severity (p = 0.13). Higher levels of ET-1 were observed in the form of overlap (1.49 to 6.82 pg / ml). CONCLUSION: The levels of ET-1 in scleroderma were inferior to controls. There was no association of ET-1 levels with the variables studied.

A leucemia representa numericamente cerca de 3% de todos os tipos de câncer. As leucemias agudas têm como principal característica o acúmulo de células jovens (blásticas) anormais na medula óssea, que substituem as células sanguíneas normais. No presente estudo, durante o período de julho de 2009 a julho de 2011, analisaram-se 29 prontuários de pacientes com leucemias agudas, internados no Hospital Universitário Evangélico de Curitiba. Avaliaram-se os seguintes dados nos prontuários: sexo, idade, cor, profissão, queixa principal, data do diagnóstico, classificação da leucemia, hemograma de admissão e de saída, mielograma, protocolo de quimioterapia, complicações, antibioticoterapia, óbito e causa mortis. Encontrou-se uma prevalência de 75,9% (n=22) casos de LMA (leucemia mieloide aguda) sobre 24,1% (n=7) casos de LLA (leucemia mieloide aguda). A idade média encontrada foi 39,7 anos. Houve uma predominância de pacientes do sexo feminino e brancos. A queixa principal encontrada com maior frequência foi astenia/fraqueza (51,7%). Foram detectados blastos no sangue periférico de 58,6% dos pacientes no momento da admissão. A taxa de mortalidade correspondeu a 51,7%, sendo choque séptico a causa mais comum
Leukemia is numerically about 3% of all cancers. The acute leukemia has as main characteristic the accumulation of immature white blood cells (blast) abnormal bone marrow, replacing normal blood cells. During the period of July 2009 to July 2011 there were analyzed medical records of 29 patients with acute leukemia admitted in a University Hospital in Curitiba. We evaluated the following information on the medical records: sex, age, race, profession, chief complaint, date of diagnosis, classification of leukemia, blood counts of entry and exit, bone marrow, chemotherapy protocol, complications, antibiotic therapy, death and cause of death. We found a prevalence of 75.9% (n = 22) cases of AML, over 24.1% (n = 7) cases of ALL. Mean age was 39.7 years. There was a predominance of females and white race. The chief complaint found more frequently was asthenia / weakness (51.7%). Blasts were detected in peripheral blood of 58.6% of patients on admission. The mortality rate amounted to 51.7%, and septic shock was the most common cause.
RESUMO
OBJECTIVE: To evaluate the intima-media thickness of the common carotid artery in patients with and without scleroderma; to verify a possible association with disease severity; to assess the relationship of intima-media thickness with known cardiovascular risk factors. METHODS: In a case-control study, were selected 30 patients with scleroderma and 30 without the disease and matched according to age, sex and cardiovascular risk factors such as hypertension, diabetes mellitus and hypercholesterolemia. The age ranged from 17 to 79 years (mean 49). All patients underwent carotid artery evaluation by high-resolution vascular Doppler in order to measure the intima-medial thickness of the carotid 2 cm from the bifurcation. In all the analysis was considered the greatest value of intima-media thickness in right and left carotid arteries. RESULTS: The sample consisted of 30 patients, being 29 (96.67%) women and one man (3.3%). In this sample, 11/30 (36.67%) had high blood pressure, 5/30 (16.67%) had diabetes mellitus, 6/30 (20%) had dyslipidemia and 2/30 (6.67%) were smokers. Comparing the measure of the increased risk (maximum intima-media thickness between the left and right side), was obtained an average of 0.77 mm for group scleroderma and a value of 0.70 mm for the control group (p = 0.21). In assessing the association between disease severity and carotid intima-media thickness, was found no significant association (p= 0.925). CONCLUSION: Was found a slight increase in intima-medial thickness of common carotid artery in patients with scleroderma but without statistical significance. Regarding the severity of the disease and intima-medial thickness of common carotid artery, there was no significant difference.

OBJETIVO: Avaliar a presença da ET-1 em pacientes portadores de esclerodermia e a sua correlação com o nível de atividade da doença; verificar se os níveis de endotelina estão associados com o perfil clínico e de autoanticorpos da esclerodermia e, ainda, se há associação com lesão microvascular detectada pela capilaroscopia periungueal. MÉTODOS: Um total de 74 pacientes, sendo 37 portadores de esclerodermia e o restante controle, foram submetidos à dosagem de ET-1 por meio de teste de ELISA. Pacientes com esclerodermia foram analisados através de um questionário sobre características da doença e pesquisa de autoanticorpos. A gravidade da doença foi definida pelos critérios de Medsger e a doença microvascular foi acessada através de capilaroscopia periungueal. RESULTADOS: Dos 37 pacientes com esclerodermia três (8,1%) eram homens e 34 (91,89%) mulheres, com idade média de 48,97 ? 13,36 anos e tempo médio de doença de 42,54 ? 13,35 anos. Os valores da ET-1 nos controles foram de 0,41 a 5,65 pg/ml (mediana de 2,26 pg/ml) e nos com esclerodermia de 0,41 a 8.82 pg/ml (mediana de 0,41 pg/ml) com p de 0,0007. Não houve correlação com o tempo de doença, idade do paciente e com o nível de acometimento cutâneo. Não encontrou-se correlação entre nível de ET-1 sérica e gravidade da doença (p=0,13). Níveis maiores de ET-1 foram observados na forma de superposição (1,49 a 6,82 pg/ml). CONCLUSÃO: Os níveis de ET-1 em esclerodérmicos mostraram-se inferiores aos controles. Não houve associação dos níveis de ET-1 com as variáveis estudadas.

OBJETIVO: Avaliar a espessura da camada médio-intimal da artéria carótida comum em pacientes com e sem esclerodermia e verificar possível associação com sua gravidade. MÉTODOS: Em estudo caso-controle, foram selecionados 30 pacientes com esclerodermia e 30 sem a doença e pareados de acordo com a idade, sexo, hipertensão arterial sistêmica, diabete melito e hipercolesterolemia. Todos os pacientes foram submetidos à avaliação das artérias carótidas pela ultrassonografia vascular de alta resolução e realizada a medida do espessamento da camada médio-intimal das carótidas comuns a 2cm da bifurcação carotídea. Em toda a análise foi considerado o maior valor da camada médio-intimal nas artérias carótidas direita e esquerda. RESULTADOS: A amostra foi composta de 30 pacientes estudados, sendo 29 (96,67%) mulheres e um homem (3,3%) com idade de 17 a 79 anos (média de 48 anos). Nesta amostra existiam 11/30 (36,67%) com hipertensão arterial, 5/30 (16,67%) com diabete melito, 6/30 (20%) com dislipidemia e 2/30 (6,67%) fumantes. Ao comparar a medida do maior risco (espessura máxima entre o lado esquerdo e o lado direito), obteve-se média de 0,77mm para o grupo esclerodermia e valor de 0,70mm para o grupo controle (p=0,212). Ao avaliar a associação entre gravidade da doença e a camada médio-intimal da carótida, não se encontrou associação significativa (p=0,925). CONCLUSÃO: Encontra-se discreto aumento do espessamento da camada médio-intimal da artéria carótida comum em pacientes com esclerodermia, mas sem significância estatística. Com relação à gravidade da doença e o espessamento da camada médio-intimal da carótida comum, não foi verificada diferença.
