OBJECT Patients with high-grade gliomas have poor prognoses following standard treatment. Generally, malignant brain tumors have a decreased blood flow that results in increased resistance to radiation and reduced delivery of chemotherapeutic agents and oxygen. The aim of the present study was to assess the effect of spinal cord stimulation (SCS) on(More)
Tumor hypoxia is an adverse factor for chemotherapy and radiotherapy. Ozone therapy is a non-conventional form of medicine that has been used successfully in the treatment of ischemic disorders. This prospective study was designed to assess the effect of ozone therapy on tumor oxygenation. Eighteen subjects were recruited for the study. Systemic ozone(More)
BACKGROUND Progressive radiation-induced cystitis can become a serious clinical problem the therapeutic solution of which is limited and almost invariably aggressive. Ozone therapy is a nonconventional therapy that has been reported to offer benefits in late-onset wound healing and ischemic disorders. This report describes a patient with progressive(More)
Malignant brain tumors have been shown to decrease O2 and blood flow resulting in hypoxia and low perfusion that in turn reduce radiation sensitivity and access by chemotherapeutic agents. Spinal cord stimulation (SCS) is a procedure that has been used quite successfully in the treatment of pain and ischemic syndromes. In the present study the authors(More)
PURPOSE Radiation-induced brain injury (RBI) is an insidious side-effect of radiotherapy mediated by vascular alterations, inflammation and ischaemia. In previous studies we had shown potential increases in loco-regional blood flow and glucose metabolism in brain tumours by using electrical cervical spinal cord stimulation (SCS). In this preliminary report(More)
Haemoglobin concentrations and tumour-pO(2) were evaluated pre-therapy in 30 patients with head and neck cancers. Anterior tibialis muscle-pO(2) was additionally measured in 16 of these patients. Tumour-pO(2) was lower in the most anaemic patients (P=0.032) and correlated with muscle-pO(2) (r=0.809, P<0.001). These results suggest that haemoglobin(More)
PURPOSE To assess the expression of IGF-1R in cervix carcinoma patients treated by radiotherapy and concomitant chemotherapy, its relation to clinical and pathologic prognostic factors and its role in predicting clinical outcome. MATERIALS AND METHODS Sixty consecutive patients suffering from localized cervix carcinoma were prospectively included in this(More)
5031 Background: Sequential measurements of CA125 have been used in a longitudinal algorithm to assess the risk of ovarian cancer. Rising CA125 followed by transvaginal sonography can achieve high specificity (99.6%) and positive predictive value (36%), but as 20% of ovarian cancers do not express CA125, sensitivity will not be optimal for preclinical(More)
Three immunohistochemically different myelomonocytic subtypes, i.e. MRP8, MRP14 and 27E10 were quantitatively evaluated in the intraalveolar, alveolar-interstitial and alveolar-intracapillary lung compartments. Lung sections from 5 major groups with defined causes of death, i.e. drowning and death during immersion (DI), cerebral/intracranial haemorrhages(More)
