    Notes: Abstract Gene amplification is a model of proto-oncogene alterations occasionally observed in human tumors. This amplification can, in some cases, have prognostic value (N-myc in neuroblastoma, c-erbB2 and int-2 in breast cancer, etc.). Amplifications of the proto-oncogenes c-myc, c-erbB2 and int-2 have not yet been report in prostate adenocarcinoma, which, like breast cancer, is hormone dependent. We sought amplifications of these three proto-oncogenes by means of Southern blotting in 15 human prostate adenocarcinoma specimens, most of which were advanced (7 stage C and 6 stage D1 or D2). We confirmed the lack of c-myc and c-erbB2 amplification, regardless of the stage, in contrast to the case of breast cancer. Int-2 amplification was observed in one advanced tumor with bone metastases, out of a total of six stage D tumors. The precise frequency of int-2 amplification and its role in prostate carcinogenesis remain to be determined.

    Notes: Abstract Objective: To evaluate the impact of noninvasive positive pressure mechanical ventilation (NPPV) on ventilator-associated pneumonia (VAP). Design: Prospective observational study. Setting: Medical intensive care unit (ICU) of a university teaching hospital. Patients: Cohort of 320 consecutive patients staying in the ICU more than 2 days and mechanically ventilated for ≥ 1 day. Measurements and results: VAP was diagnosed when, satisfying classical clinical and radiological criteria, fiberoptic bronchoalveolar lavage and/or protected specimen brush grew ≥ 104 and ≥ 103 CFU/ml, respectively, of at least one microorganism. Patients were classified into four subgroups according to the way in which mechanical ventilation was delivered: NPPV then tracheal intubation (TI) (n = 38), TI then NPPV (n = 23), TI only (n = 199), and NPPV only (n = 60). Occurrence of VAP was estimated by incidence rate and density of incidence. Risk factors for VAP were assessed by logistic regression analysis. Twenty-seven patients had 28 episodes of VAP. The incidence rates for patients with VAP were 18 % in NPPV-TI, 22 % in TI-NPPV, 8 % in TI, and 0 % in NPPV (p 〈 0.0001). The density of incidence of VAP was 0.85 per 100 days of TI and 0.16 per 100 days of NPPV (p = 0.04). Logistic regression showed that length of ICU stay and ventilatory support were associated with VAP. Conclusions: There is a significantly lower incidence of VAP associated with NPPV compared to tracheal intubation. This is mainly explained by differences in patient severity and risk exposure.

    Captopril induces correction of postrenal transplant erythremia (1990)

    Notes: Abstract Kidney transplant patients may develop post-transplant erythremia (PTE), and in order to avoid thromboembolism venesection, anticoagulation and native kidney removal have been suggested. We propose captopril as an alternative therapy for PTE. Seven hypertensive PTE patients, aged 42±10 years with stable renal function, were investigated to exclude primary or secondary polycythemia. All patients manifested true erythrocytosis [red blood cells (RBC) mass〉20% of predicted level] with concomitant increases in hematocrit and hemoglobin levels. Captopril was introduced in gradually increasing doses up to 75 mg/day under careful monitoring of blood pressure and renal function. Weekly follow-up was arranged to evaluate drug efficacy. After captopril, a significant reduction with normalization of the RBC mass (42±4 vs 31±5 ml/kg; P〈0.005) was observed. The RBC counts and hematocrit and hemoglobin levels also decreased. One patient had recurrent erythrocytosis after captopril withdrawal. Captopril may be a simple, effective, and non aggressive treatment for postrenal transplant erythremia.
