Efficacy of High-Ozonide Oil in Prevention of Cancer Relapses Mechanisms and Clinical Evidence.

BACKGROUND: Cancer tissue is characterized by low oxygen availability triggering neo angiogenesis and metastatisation. Accordingly, oxidation is a possible strategy for counteracting cancer progression and relapses. Previous studies used ozone gas, administered by invasive methods, both in experimental animals and clinical studies, transiently decreasing cancer growth. This study evaluated the effect of ozonized oils (administered either topically or orally) on cancer, exploring triggered molecular mechanisms. METHODS: In vitro, in lung and glioblastoma cancer cells, ozonized oils having a high ozonide content suppressed cancer cell viability by triggering mitochondrial damage, intracellular calcium release, and apoptosis. In vivo, a total of 115 cancer patients (age 58 ± 14 years; 44 males, 71 females) were treated with ozonized oil as complementary therapy in addition to standard chemo/radio therapeutic regimens for up to 4 years. RESULTS: Cancer diagnoses were brain glioblastoma, pancreas adenocarcinoma, skin epithelioma, lung cancer (small and non-small cell lung cancer), colon adenocarcinoma, breast cancer, prostate adenocarcinoma. Survival rate was significantly improved in cancer patients receiving HOO as integrative therapy as compared with those receiving standard treatment only. CONCLUSIONS: These results indicate that ozonized oils at high ozonide may represent an innovation in complementary cancer therapy worthy of further clinical studies.

Multidisciplinary management of spontaneous spinal infections: is there a correlation between timing, type of treatment and outcome?

BACKGROUND: Spontaneous spinal infections (SSIs) represent a rare and serious pathological entity. We tried to study a correlation between type of treatment, timing of treatment and clinical outcome through a multivariate analysis of an observational cohort study with the aim to define what is the optimal clinico-therapeutic management. METHODS: We performed a retrospective observational cohort study on all consecutive patients observed in our Institute in a period of 13 years; from 2001 to 2014 we enrolled 50 consecutive patients with symptomatic spontaneous spinal infections (no previous surgery or recent infection in other site), confirmed with diagnostic imaging. The inclusion parameters were: diagnostic imaging, signs and symptoms positive for SSI, no history of recent infection or surgery. Of each parameter analyzed, we calculated mean and standard deviation and when necessary correlation (ρ), covariance (σ) and relation coefficient between type of treatment, timing of treatment and clinical outcome. RESULTS: Our results suggest that an increase of one day from the onset of symptoms and the start of therapy leads to an increase in the Oswestry Disability Index Scale both at 6 months than at 1 year, with a statistical relevance, so our experience shows a statistically significant correlation and a positive co-variance between timing and outcome at 6 months and 1 year. CONCLUSIONS: SSI are rare, very difficult to diagnose and represent a significant clinical problem. If not properly managed, they may lead to significant impact in the quality of life. The most relevant problem is not the treatment, conservative or surgical, but early diagnosis, so a careful physical, laboratory and imaging examination is fundamental, with an important help provided by isolation of the pathogen and histology. In our experience early diagnosis has a fundamental role. In the light of this, current treatment protocols may require a prompt and multidisciplinary management including infectivologists, neuroradiologists and spine surgeons.

Autologous Skull Bone Flap Sterilization After Decompressive Craniectomy: An Update.

OBJECTIVE: To report new results with ethylene oxide sterilization and new experiences with autogenous bone flaps autoclaved at a high or low temperature for preservation of a bone flap after decompressive craniectomy. METHODS: In 45 patients who underwent a decompressive craniectomy, we determined bone flap preservation with ethylene oxide and with high- or low-temperature autoclave sterilization. RESULTS: The bone flap was repositioned after a mean of 10 weeks in the ethylene oxide group and after 6 weeks in the other sterilization groups. A bone flap infection developed in 1 patient (2%), which required removal and subsequent methyl methacrylate cranioplasty. In 1 child, the bone flap had partially reabsorbed after 12 months. In all other patients, esthetic results were good after an average follow-up of 42 months. At follow-up, computed tomography or magnetic resonance imaging of the bone flap showed preservation of structural features with apparent fusion and revitalization at the bone flap margins. CONCLUSIONS: Ethylene oxide and high- or low-temperature autoclave bone sterilization techniques for the preservation of autologous bone flaps after decompressive craniectomy were safe, rapid, and inexpensive.
