RESUMO

von Willebrand factor (vWF) is a protein that mediates platelet adherence to the subendothelium during primary hemostasis. High plasma vWF concentrations have been reported in patients with various types of cancer, such as head and neck, laryngeal and prostatic cancer, probably representing an acute phase reactant. In the present study we determined the plasma levels of vWF antigen (vWF:Ag) by quantitative immunoelectrophoresis in 128 female patients with breast cancer as well as in 47 women with benign breast disease and in 27 healthy female controls. The levels of vWF:Ag were 170.7 + or - 78 U/dl in patients with cancer, 148.4 + or - 59 U/dl in patients with benign disease and 130.6 + or - 45 U/dl in controls (P<0.005). We also detected a significant increase in the levels of vWF:Ag (P<0.0001) in patients with advanced stages of the disease (stage IV = 263.3 + or - 113 U/dl, stage IIIB = 194.0 + or - 44 U/dl) as compared to those with earlier stages of the disease (stage I = 155.3 + or - 65 U/dl, stage IIA = 146.9 + or - 75 U/dl). In conclusion, vWF levels were increased in plasma of patients with malignant breast disease, and these levels correlated with tumor progression

RESUMO

BACKGROUND: The high frequency of alcohol related problems highlights the importance of its approach. The association of both the alcohol-abuse and alcohol related diseases has been pointed in the literature and are often the main reason for hospitalization. Physicians use different tools to detect abusive drinkers, and one of them is the CAGE-test, validated by Mayfield et al. in 1974. OBJECTIVES: To study the association between the result of the CAGE-test and the perception and registration of alcohol abuse by the medical staff and the nurses in charge of inpatients of Hospital de Clínicas de Porto Alegre, southern Brazil. MATERIAL AND METHOD: The design involved three phases. First, the application of the CAGE-test to the 385 eligible patients. Second, review of all 51 CAGE-positive patients' records as well the controlled evaluation of 51 randomized CAGE-negative patients, to seek alcoholic habits and alcohol-related diseases. Third, interview with the medical staff to find out their perception about these subjects. RESULTS: We found 51 patients CAGE-positive (prevalence = 13%). When evaluated through the registration and through a standardized interview, medical staff and nurses were not aware of more than half of CAGE-positive patients. No significant differences were found between medical staff registration and perception; the prevalence of alcohol related diseases was the same for both: 26 and 27% (p = .861). The prevalence of alcohol related diseases was higher among CAGE-positive patients (p = .0003). CONCLUSIONS: In spite of the high prevalence among our patients, alcohol abuse is not pursued by our health teams as it should be. As for the future, there is reason to envision a continuing alcoholism rapprochement.

RESUMO

Objetivo. Avaliar a associaçao entre o resultado do teste CAGE aplicado em pacientes internados num hospital geral universitário (Hospital de Clínicas de Porto ALegre - HCPA) e a percepçao e registro de abuso de álcool e de doenças relacionadas pelas equipes de saúde. Pacientes e Métodos. O delineamento envolveu três fases: a) aplicaçao do teste CAGE aos 385 pacientes adultos e adolescentes internados considerados elegíveis para o estudo; b) revisao dos prontuários dos pacientes CAGE-positivo e de um número igual de pacientes CAGE-negativo, estratificados por área de internaçao e sorteados, para identificar hábitos alcoólicos e a presença de doenças relacionadas ao uso de álcool; c) entevista com os membros das equipes médicas responsáveis para avaliar sua percepçao sobre o hábito alcoólico em seu paciente. As diferenças encontradas foram analisadas através do teste Qui-quadrado e do teste t de Student, com significância estatística em nível de 5 por cento bicaudal. Resultados. Foram encontrados 51 pacientes CAGE-positivo (13 por cento). A equipe médica registrou abuso de álcool no prontuário de 51 por cento dos pacientes CAGE-positivo e 10 por cento dos CAGE-negativo, e a equipe de enfermagem fez este registro no prontuário de 31 por cento dos pacientes CAGE-positivo e 8 por cento dos CAGE-negativo (p=.724). Nao houve diferença entre o registro e a percepçao da equipe médica (p=.184). A prevalência de doenças relacionadas ao abuso de álcool foi 27 por cento quando se examinou os prontuários médicos e 26 por cento quando se entrevistou a equipe médica (p=.861), sendo maior entre os pacientes CAGE-poistivo (43 por cento) do que entre os CAGE-negativo (10 por cento) (p=.0003). Conclusoes. O abuso de bebidas alcoólicas e a presença de doenças associadas ao mesmo sao condiçoes prevalentes nos pacientes admitidos ao HCPA. Entretanto, mais de metade dos casos nao foram detectados pela equipe de saúde, havendo correspondência entre os registros de prontuário e a entrevista.

RESUMO

Large cell calcifying Sertoli cell tumor of the testis is an extremely rare type of sex cord tumor with low malignant potential that occurs in the first and second ecades of life. Twenty-eight cases have been reported in the literature and, to our knowledge, only 2 had an aggressive behaviour. Patient age, tumor size, histological malignant patterns such as pleomorphism and high mitotic rate seem to heavy influence the future neoplasm malignancy. Ultrasonography imaging of the large cell calcifying has described in only 6 cases. We report an experience with a large cell calcifying Seroli cell tumor of the testis and point out the unusual sonographic findings. Moreover, if histologic examination suggests no malignant features, we suggest local excision as ideal therapy for the preservation of testicular parenchyma.

RESUMO

OBJECTIVE: Antibiotic prophylaxis in prosthetic surgery was administered prospectively according an original protocol. Routine pre-operative preparation included also scrupulous, repeated disinfection of the skin of the genital and perineal region. METHODS: Vancomycin 500 mg i.v. every 6 h on the day of surgery and gentamicin 1 mg/kg i.v. every 8 h on the day of surgery and for the following 48 h were administered to 75 consecutive patients. Overall 87 prosthetic devices were implanted. The patients were evaluated at 6 weeks and at 6 months after surgery. RESULTS: No infection was observed. CONCLUSION: Support from this study to antibiotic prophylaxis in penile prosthetic surgery is uncertain. The importance of scrupulous routine pre-operative preparation is probably underestimated.
