We undertook this phase II study to evaluate the efficacy and toxicity of epidoxorubicin and ifosfamide in the treatment of locally advanced and/or metastatic soft-tissue sarcomas. We used escalating doses of epidoxorubicin (from 60 to 75 mg/m2) on day 1 and 1.2 g/m2 ifosfamide on days 1-5. Chemotherapy courses were repeated every 3-4 weeks. A total of 16 patients--13 who had not previously been treated and 3 who had undergone prior therapy with anthracyclines--entered the study. In all, 15 patients were evaluable for response and 16, for toxicity. At least two courses of chemotherapy were given. A complete remission (CR) was seen in 1 patient, a partial remission (PR) in 5, and a minor response (MR) in 1, for an objective response rate (CR + PR) of 40% (6/15); this value reached 50% in non-pretreated patients (6/12). Stable disease (SD) was observed in 40% (6/15) of patients. The relative dose intensity of epidoxorubicin ranged from 10 to 23.3 mg/m2 (median, 16.6 mg/m2). The time to objective response ranged from 4 to 12 weeks (median, 8.5 weeks). The duration of response was 4 months for the single CR, and that for the five PRs was 6+ months (range, 4-18 months). Toxicity was evaluated according to WHO criteria in 16 patients; it was mild and consisted mainly of alopecia, nausea and vomiting, and leucopenia. In only three patients did we observe grade 3 leucopenia. In one case an ifosfamide-associated encephalopathy occurred, but it regressed after 24 h. Neither chronic nor acute cardiac toxicity was reported. In this preliminary analysis, the response rate obtained with the combination of epidoxorubicin and ifosfamide was encouraging and the toxicity was acceptable.  相似文献

OBJECTIVE: To examine the efficacy of intravenous porcine secretin for the treatment of autistic disorder. METHOD: Randomized, double-blind, placebo-controlled, crossover design. Fifty-six subjects with autistic disorder received either a secretin or placebo infusion at baseline and the other substance at week 4. Subjects were given the Autism Diagnostic Observation Schedule (ADOS) and other pertinent developmental measures at baseline and at weeks 4 and 8 to assess drug effects. RESULTS: For the primary efficacy analysis, change of ADOS social-communication total score from week 0 to week 4, no statistically significant difference was obtained between placebo (-0.8 +/- 2.9) and secretin groups (-0.6 +/- 1.4; t54 = 0.346, p < .73). The other measures showed no treatment effect for secretin compared with placebo. CONCLUSION: There was no evidence for efficacy of secretin in this randomized, placebo-controlled, double-blind trial.  相似文献

Tumor Associated Glycoprotein 72 (TAG-72) is common to most epithelial tumors. In this study serum levels of TAG-72 were measured in 36 healthy female subjects, in 94 patients with breast cancer, and in 43 others with epithelial ovarian cancer. More particularly, 27 out of the 94 patients with breast cancer had early disease (Stage I-I; or T 0-2b; N 0-1b; M 0), while the remaining 67 had advanced disease (Stage III-IV; or T 0-4; N 0-3; M 0-1). All the 43 subjects with ovarian cancer were at stage III-IV (FIGO Classification), 12 of whom had minimal disease (lesions less than 2 cm) and the other 31 had bulky disease. 3.5 U/ml being the highest value found in the control group, we arbitrarily assumed 3.85 U/ml (mean +/- 3 SD) as the cut-off limit in this preliminary study. Among the patients with breast cancer, 17 out of the 67 subjects with advanced disease (25.3%) and 1 out of the 27 others with early disease (3.7%) exceeded the TAG-72 cut-off limit. Among the patients with ovarian cancer, 2 out of the 12 subjects with minimal disease (16.7%) and 22 out of the others 31 with bulky disease (70.9%) had TAG-72 levels above cut-off limit. High TAG-72 levels were found in all the histotypes of ovarian cancer including the mucinous type. Preliminary data seem to indicate that in ovarian cancer variations in serum levels of TAG-72 are in agreement with the trend of the disease.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

PURPOSE: To describe the procedural details for primary prevention of type II endoleak with fibrin glue injection into the aneurysm sac at the time of endografting. TECHNIQUE: After deployment of the main stent-graft component, the angiographic pigtail catheter is withdrawn, leaving the 0.035-inch standard guidewire between the endograft and the native aorta. Through a brachial-femoral arterial guidewire loop, an 11-cm-long, 6-F introducer is advanced over the wire into the contralateral iliac artery. After deployment of the contralateral iliac extension, a 23-cm, 5-F sheath is advanced over the wire into the aneurysm sac. The wire and vessel dilator are removed, leaving the cannula in the sac. To prevent distal embolization of the sealant, a balloon is inflated in the contralateral limb to secure it to the native vessel before 5 mL of fibrin sealant are injected into the sac via a double-syringe delivery system inserted through the sheath. The balloon is left in place for 1 minute after sealant injection. In 64 consecutive patients in whom this technique has been used, sac embolization has been successful. There have been no intraoperative complications or in-hospital mortality. Over a mean follow-up of 9.3+/-4.4 months (range 1-18), only 1 lumbar endoleak has been detected on surveillance imaging. CONCLUSIONS: This preventive strategy appears to be an effective approach and the best therapeutic choice for preventive management of type II endoleak.  相似文献

Purpose:   This retrospective study aims to review the electroclinical features of patients presenting with eyelid myoclonia (EM) with and without absences.
Methods:   The Italian chapter of the International League Against Epilepsy (ILAE) has been conducting an electroclinical study of patients with EM. Among these, we searched for and selected the patients presenting with both impairment of intellectual functions and a peculiar ictal electroencephalography (EEG) pattern, that is, a discharge of fast generalized polyspikes/polyspikes and waves.
Results:   We found 18 patients matching this electroclinical picture. All the patients were photosensitive. All of them had associated generalized, mostly nocturnal, tonic–clonic seizures. During the evolution, 13 patients presented episodes of EM status. Despite adequate antiepileptic treatment, the patients remained drug resistant for many years or throughout the evolution. The degree of impairment of intellectual functions varied from borderline level to moderate mental retardation.
Discussion:   The patients we described herein can be considered a homogeneous group in the more heterogeneous group of patients presenting with EM. Further clinical and, more probably, genetic studies will clarify whether this condition could be considered a specific and homogeneous condition in the more heterogeneous group of patients presenting with EM.  相似文献

This study aims to define the usefulness of antibiotic prophylaxis of urinary tract infection (UTI) in postmenopausal female undergoing invasive urodynamics (IU). Two hundred sixty-two postmenopausal females underwent IU. Before urodynamics, all females were double blindly randomized in two age stratified groups. Group 1 (130 patients) received oral antibiotic prophylaxis with a single 400-mg dose of norfloxacin. Group 2 (132 patients) received norfloxacin placebo. Statistical analysis was performed by a chi (2) test to evaluate differences between groups for UTI incidence rate. Fifty-four patients of 262 (20.6%) resulted affected by UTI [24 of 130 subjects who received antibiotic prophylaxis (18.4%) and 30 of 132 subjects who received placebo (22.7%)]. There was no statically significant difference (P = 0.242) regarding UTI incidence rate between patients who received and those who did not received antibiotic prophylaxis. UTI incidence rate in postmenopausal women undergoing urodynamics is not affected by administration of antibiotic prophylaxis at the desired level of efficacy.  相似文献

One of the most significant challenges confronting orchid researchers is the lack of specific molecular markers, mainly for species in the Neotropics. Here we report the first set of specific chloroplast microsatellite primers (cpSSR) developed for Neotropical orchids. In total, nine polymorphic cpSSR loci were isolated and characterized in four species occurring in the Brazilian Atlantic Rainforest: Epidendrum cinnabarinum, E. denticulatum, E. fulgens and E. puniceoluteum. Levels of intraspecific polymorphism were characterized using two populations for each species, with 13–20 individuals each. Allele numbers varied from two to three per locus, while the number of haplotypes ranged from three to six per species. Extensive differentiation among the taxa was detected. All markers were successfully cross-amplified in eight other different genera. These cpSSRs markers will enable novel insights into the evolution of this important Neotropical genus.  相似文献

We previously demonstrated that intradermal and intramuscular vaccination with Leishmania amazonensis promastigote antigens (LaAg) increases the susceptibility of BALB/c mice to cutaneous leishmaniasis. In this study, we investigated the role played by serine and cysteine proteases as disease-promoting components of LaAg. Mice were immunized by the intramuscular route with LaAg that was pre-treated with a pool of serine or cysteine protease inhibitors (SPi and CPi, respectively) prior to infection with L. amazonensis. Neutralization of either enzyme type reversed the disease-promoting effect of LaAg, as seen by the slower lesion development. However, the parasite burden was only effectively controlled in mice receiving SPi-treated LaAg. Protection was associated with diminished production of TGF-β and particularly IL-10 in response to parasite antigens by the lesion-draining lymph node cells of vaccinated mice relative to control. In vitro, soluble proteases isolated from LaAg (LaSP-Sol) directly activated IL-4, IL-10 and TGF-β production by immune cells. Like native LaAg, vaccination with LaSP-Sol primed mice to respond to parasite challenge with a strong Jones-Mote cutaneous hypersensitivity reaction, and increased susceptibility to infection. Furthermore, neutralization of serine but not cysteine proteases blocked the capacity of LaAg to sensitize mice for Jones-Mote reaction. Together, these results indicate that soluble serine proteases are key components of LaAg responsible for its disease-promoting immunity.  相似文献
