OBJECTIVE: The present study was designed specifically to assess the relationship between brain morphology and outcome in schizophrenia. METHOD: Fifty-six schizophrenic patients and a matched group of 32 healthy subjects were studied with magnetic resonance (MR) imaging scans. Clinical assessment included the Krawiecka-Manchester Scale (K-MS) and the Outcome scale by Strauss and Carpenter. RESULTS: Along several neuromorphological measures the patients differed from controls only for right and left ventricular volumes. The 'poor outcome' patients had a left and right ventricular enlargement when compared to the 'good outcome' patients and healthy controls. A regression analysis showed that right ventricle volume, left temporal lobe volume and left hippocampal volume entered into the regression equation, accounting for a 27% of the outcome measure. CONCLUSION: The outcome does not seem to be predicted by one particular morphological site but involves different brain regions; however, the ventricular enlargement identifies a subgroup of patients with poor outcome. 相似文献

BACKGROUND: Ozone is a photochemical oxidant pollutant that is an important public health hazard. Although the inflammatory response that occurs in response to ozone inhalation is well characterized, the mechanisms underlying epithelial cell activation are not well understood. OBJECTIVE: Because the epidermal growth factor receptor (EGFR) is a central regulator of epithelial function, we tested the hypothesis that nasal epithelial cells respond to ozone-induced oxidant stress by modulating expression of the EGFR and its ligands, EGF and transforming growth factor-alpha (TGF-alpha). METHODS: Normal volunteers were exposed to air or 400 parts per billion ozone for 2 hours, and then nasal biopsy specimens were harvested 6 hours later for immunohistochemical analysis of EGFR, EGF, and TGF-alpha. Nasal epithelial cell cultures were exposed in vitro to ozone or TNF-alpha; mediator release was measured by ELISA and cellular EGFR expression by immunoblotting and fluorescence-activated cell sorting analysis. RESULTS: Epithelial expression of the EGFR, EGF, and TGF-alpha were all significantly (P <.05) increased in the nasal biopsy specimens after ozone exposure, and there was a significant positive correlation between EGFR expression and the increase in neutrophil numbers in the nasal epithelium (P =.001, rho = 0.87). In vitro exposure of primary nasal epithelial cell cultures to ozone had no effect on EGFR expression, even though IL-8 release was enhanced. In contrast, exposure to TNF-alpha caused EGFR levels to increase significantly. CONCLUSION: These data suggest that the ozone-induced increase in EGFR expression observed in vivo is indirect, perhaps mediated by neutrophil-derived TNF-alpha. 相似文献

The results are presented of a retrospective clinical study carried out on 341 patients affected with cancer of the uterine cervix, with lymphography in the pretreatment diagnostic work-up, treated in our Institute from January 1961 to December 1976. The clinical classification of the patients studied was: 157 cases in Stage I (46.0%), 95 cases in Stage II (27.9%), and 89 cases in Stages III and IV (26.1%). During the period considered, the therapeutic approach for carcinoma of the cervix was practically constant and in line with the therapeutic policy most frequently followed for these neoplasms. For the early stages (9/341 patients or 27.6%) preference was given to a radical surgery and postoperative radiotherapy combination; for borderline cases and "bulky" and "barrel-shaped" lesions, radiotherapy usually preceded surgical treatment to enlarge its indications and improve its results (36/341 patients or 10.5%). The cases that were more developed locally or that presented contraindications to surgery received radiological treatment alone (211/341 patients or 61.9%). Radiotherapy treatment consisted of radium therapy performed with a single application of 226Ra conventional sources, followed by percutaneous irradiation with 60Co-teletherapy in the more developed cases and/or in the presence of lymph node metastases. All the patients were submitted to diagnostic lymphography at the onset of the treatment and 92 (26.9%) had lymph node metastases. In the framework of this clinical review, the 5-year disease-free survival from onset of the treatment varied from 88.2% for the cases at Stage Ib occult, 72.5% for the cases at Stage Ib, 63.8% for the Stage II cases, to 40.5% for the cases at Stage III and IV. The presence of a pathologic report at lymphography makes a considerable difference in terms of disease-free, long-term survival after treatment 相似文献

Bronchial hyperresponsiveness and airway inflammation markers in nonasthmatics with allergic rhinitis. 总被引:10,自引:0,他引:10

Bronchial hyperresponsiveness (BHR) is a characteristic feature of asthma which is often associated with airways inflammation. However, some patients with allergic rhinitis and no clinical evidence of asthma also exhibit BHR. This study therefore investigated whether inflammatory cell infiltrate is present in the induced sputum of nonasthmatic subjects with allergic rhinitis during the pollen season and examined its relationship with airway hyperresponsiveness to inhaled methacholine and adenosine 5'-monophosphate (AMP). Twenty subjects (12 allergic rhinitis, eight nonallergic controls) underwent methacholine and AMP challenge and sputum induction with hypertonic saline on separate days. Cell differentials were calculated from whole sputum samples. A significantly greater number of eosinophils was found in the sputum of nonasthmatic subjects with allergic rhinitis compared to that of nonallergic controls, their median (range) percentages being 17.5 (4-47) and 1.5 (0-5) (p<0.001) respectively. Although sputum eosinophilia failed to be significantly associated with methacholine responsiveness (r(s)=-0.50; p=0.095), the provocative concentration of AMP causing a 20% fall in forced expiratory volume in one second correlated strongly and significantly with the absolute number of eosinophils (r(s)= -0.73; p=0.007). Eosinophil cationic protein levels in the sputum of rhinitic subjects were significantly elevated compared to controls and correlated with eosinophil number (r(s)=0.67; p=0.017). These findings support the view that bronchial eosinophilia alone is insufficient to cause asthmatic symptoms. Diverse agonists for assessing bronchial hyperresponsiveness are selectively associated with airway inflammation in allergic rhinitis. 相似文献

Forensic pathologists are often asked to provide evidence of asphyxia death in the trial and a histological marker of asphyxiation would be of great help. Data from the literature indicate that the reaction of lung tissue cells to asphyxia may be of more interest for forensic purposes than migrating cells. The lungs of 62 medico-legal autopsy cases, 34 acute mechanical asphyxia (AMA), and 28 control cases (CC), were immunostained with anti-P-selectin, anti-E-selectin, anti-SP-A, and anti-HIF1-α antibodies, in order to verify if some of them may be used as markers of asphyxia death. Results show that P- and E-selectins expression in lung vessels, being activated by several types of trigger stimuli not specific to hypoxia, cannot be used as indicator of asphyxia. Intra-alveolar granular deposits of SP-A seem to be related to an intense hypoxic stimulus, and when massively present, they can suggest, together with other elements, a severe hypoxia as the mechanism of death. HIF1-α was expressed in small-, medium-, and large-caliber lung vessels of the vast majority of mechanical asphyxia deaths and CO intoxications, with the number and intensity of positive-stained vessels increasing with the duration of the hypoxia. Although further confirmation studies are required, these preliminary data indicate an interesting potential utility of HIF1-α as a screening test for asphyxia deaths. 相似文献

OBJECTIVE: To determine whether additional physiotherapy increases botulinum toxin type A effects in reducing spasticity in patients with multiple sclerosis. DESIGN: A single-blind, randomized, controlled pilot trial with a 12-week study period. SUBJECTS: Thirty-eight patients with progressive multiple sclerosis affected by focal spasticity and who were observed at the Multiple Sclerosis Centre operating in the S. Andrea Hospital in Rome. INTERVENTIONS: For intervention all patients received botulinum toxin type A; the treatment group also received additional physiotherapy to optimize management through passive or active exercise and stretching regimens. MAIN MEASURES: To measure objective and subjective level of spasticity, patients were assessed at baseline, 2, 4 and 12 weeks post treatment by Modified Ashworth Scale and visual analogue scale. RESULTS: When compared with the control group, we found a significant decrease of spasticity by Modified Ashworth Scale (P < 0.01 by t-test) in the treatment group at week 2 (2.73 versus 3.22), week 4 (2.64 versus 3.33) and week 12 (2.68 versus 3.33). The mean (%) difference in Modified Ashworth Scale score between baseline and the end of follow-up was -0.95 (26.1) in the treatment group and -0.28 (7.7) in the control group (P < 0.01). The combined treatment proved also to be more effective by visual analogue scale (P < 0.01) at week 4 (6.95 versus 5.50) and at week 12 (7.86 versus 6.56) but not at week 2 (5.18 versus 5.50; P = 0.41). CONCLUSIONS: Our data suggest that physiotherapy in combination with botulinum toxin type A injection can improve overall response to botulinum toxin. 相似文献
