RESUMO
INTRODUCTION: The aim of the study was to assess, compliance with maintenance treatment in patients with persistent asthma in clinical practice. METHODS: This observational, cross-sectional, prospective, multicenter study was conducted in metropolitan France on patients with persistent asthma under the care of a representative sample of general practitioners and pneumologists. Compliance was determined via access to the Health Insurance database allowing comparison between the actual consumption of medications and the corresponding theoretical consumption related to prescription. Additional compliance data were obtained using the validated Morisky questionnaire. RESULTS: Eighty one physicians included 488 patients, mean age of 51 years, 55% women. The statement of consumption (SC) was available for 35% of patients however the Morisky questionnaire (present for 85% of patients) showed a similar compliance between patients with or without SC. The good compliance rate (compliance ≥80%) was observed in 51% based on the SC and in 38% based on the Morisky questionnaire. Among possible predictive factors, only obesity was associated with a bad compliance (19% vs 7%, P<0.05). Patients with poor compliances displayed more severe symptoms and a higher rate of non-control (21.7% vs 5.7%, P<0.01). CONCLUSIONS: The statement of consumption is a useful tool to provide quantitative measurement of compliance in daily practice.

Many reports have been published concerning the efficacy of hyperthermic antiblastic perfusion (HAP) for the treatment of recurrent limb melanoma. In terms of tumour response, loco-regional control and survival, the results vary greatly even in patients with the same disease stage treated with the same technique. The aim of the present report was therefore to compare the experiences of two institutes, the Regina Elena National Cancer Institute of Rome and the National Tumour Institute of Milan, in treating a total of 327 patients with stage IIIA and IIIAB melanoma with HAP. The study also examined whether, and to what extent some prognostic factors influence the course of the disease. The tumour temperature proved to be the most important parameter for obtaining a complete tumour response which, in turn, positively affected survival. A direct relationship was found between the rates of complete tumour response and the clinical status of the patients. The complete response rates obtained in patients with no evidence of disease were 62.5% at the Rome institute and 70.1% at the Milan institute as opposed to 23.6% and 39%, respectively, in patients who died of the disease.

The role of surgery in the treatment of primary gastric lymphoma has been recently re-evaluated. We report the results of a series of 37 operated patients for primary gastric lymphoma (PGL). All patients underwent gastrectomy with D2 lymphadenectony and bilateral liver biopsies. Postoperative histopathological classification was compared to preoperative staging data. No mortality and low morbidity were observed in this series of patients. We found a high incidence of mixed grading of tumors and a relatively high incidence of lymph node metastases in low grade lymphoma. Relying on preoperative biopsies and imaging techniques could lead to preoperative staging inaccuracy and therefore to inappropriate treatment planning. For these reasons we advocate systematic primary surgery in PGL. Surgery could be useful for staging purposes and seems to be curative in stage IE.

MR Cholangiopancreatography (MRCP) and MR Urography (MRU) are promising recent imaging modalities. Oral magnetic particles (Abdoscan, Nycomed SA, Oslo, Norway) is an oral negative contrast agent eliminating signal intensity of the gastro-intestinal tract thus improving image quality at MRCP and MRU.

Gadodiamide injection (Gd-DTPA-BMA) is a new non-ionic paramagnetic contrast agent for which the safety at the dose 0.1 mmol/kg was evaluated during a European multicentre study on a large population of adult patients who had an MR examination of the central nervous system with contrast medium. The safety analysis was performed on 2,102 patients by recording the adverse events observed during injection and up to 24 hours after the injection. Adverse events due or probably due to gadodiamide injection were observed in 102 patients (4.4%) with injection-site associated discomfort (heat, coldness, pain at the injection site) in 37 patients (1.8%) and adverse events other than discomfort (headache, nausea, vomiting) in 35 patients (3.1%). No adverse events of severe intensity or death were reported during the trial. Gadodiamide injection was shown to be safe and well tolerated and represents a non-ionic alternative to the current products in the field of MR imaging of the central nervous system.

BACKGROUND: Patients with thrombotic thrombocytopenic purpura (TTP), Moschowitz's disease, run a high risk of perioperative bleeding and need intensive hematologic support. In some patients, TTP is associated with cancer but the surgical role in these patients is still unclear. To illustrate the surgical problems and outcome we present the case histories of three patients with TTP observed in our emergency department. MATERIALS AND METHODS: Two patients had TTP secondary to cancer and one patient with primary TTP (no evidence of neoplasia) had emergency operation for gastric hemorrhage, occlusion and TTP unresponsive to plasmapheresis. RESULTS: The first two patients who had not radical resection of cancer and no splenectomy, died for TTP complications. The third patient who underwent emergency splenectomy, had an uneventful postoperative course and TTP completely regressed. CONCLUSIONS: These case reports suggest that patients with TTP should be screened to rule out cancer. In patients with acute cancer-related complications emergency surgery should aim to resect the cancer. An associated splenectomy may increase the effectiveness of postoperative hematologic therapy.

Eighty patients with locally advanced, high grade soft tissue sarcoma of the extremities were studied prospectively in order to determine the efficacy of hyperthermic antiblastic perfusion (H.A.P.) as the first step of a combined multimodality therapy. All of the patients have been evaluated in terms of functional results, loco-regional control and survival according to the different treatment schedules adopted. The first clinical trial employed H.A.P., followed by surgery alone. Because the results obtained were unsatisfactory, the protocol was modified to include a continuous intra-arterial (i.a.) infusion of doxorubicin (dx) or radiotherapy before surgery. The best results have been obtained with the radiotherapy-including protocol showing a conservative surgery rate of 100% and a 94% rate of loco-regional control. The disease-free, distant disease-free and overall survival rates were 68%, 75% and 70%, respectively. The importance of the treatment protocol has been confirmed in a multivariate analysis which demonstrated that the treatment protocol adopted is one of the prognostic factors with an independent value (p = 0.06).

Thirty-two patients with recurrent (skin) or metastatic (skin, node, or both) melanoma have been treated with a hyperthermia-cisplatin regimen. The hyperthermic treatment was carried out for 60 minutes at 43 degrees C with the MHS-SMA and the Sapic SVO3 ALENIA devices once a week. When the tumor temperature reached 42 degrees C, cisplatin was administered at a dosage of 50 mg/m2 given by intravenous bolus infusion. The treatment was repeated four times and the tumor response evaluated 4 weeks after the last treatment. Significant systemic or local toxicity was not seen. In terms of results, there were 9 patients with complete responses (28.1%), 13 with partial responses (40.6%), 8 with no change (25.0%), and two with disease progression (6.3%). The objective response rate was 68.7%. The response duration for those with complete responses ranged from 4 to 49 months (median 20 months). The median time to progression for patients with partial responses and those with no change was 6 and 5 months, respectively, with ranges of 1-7 and 1-10 months, respectively. The 4-year actuarial survival rates were 47.6% and 20.3% for the complete and incomplete responders, respectively. These results can be considered satisfactory, taking into account that most patients were pretreated with radiotherapy, chemotherapy or both, confirming the therapeutic potential of the hyperthermia and cisplatin regimen.

PURPOSE: The evaluation of lymphocyte subsets by using monoclonal antibodies in neoplastic patients has provided different results, partly in relation to the stage of the disease. Therefore, as a preliminary study of cancer patients treated with immunomodulating drugs, an analysis of lymphocyte subsets was performed in colorectal carcinoma patients. METHODS: In this study, a flow cytometric evaluation of lymphocyte subsets was performed in 33 patients affected by colorectal carcinoma, with or without metastases. RESULTS: A significant reduction of hemoglobin concentrations and hematocrit was observed in all of these subjects, associated with an evident increase of white blood cells, platelets, and HLA DR-positive T lymphocytes, whereas CD 3-CD 4-positive and CD 20-positive lymphocyte concentrations were decreased. Subjects without metastases showed an evident decrease of hemoglobin concentrations and an increase of white blood cells, platelets and CD 3-HLA DR-positive lymphocytes, while patients with disseminated disease also had reduced mean values of hematocrit, red blood cells, CD 3-CD 4-positive, and CD 20-positive lymphocytes. CONCLUSIONS: The main differences between colorectal carcinoma patients with or without metastases were represented by a decrease of red blood cells, CD 3-CD 4-positive, and CD 20-positive lymphocyte concentrations in the latter group.
