RESUMO

Chemo-induced oral mucositis (OM) is associated with significant symptoms, treatment delays and increased costs. This pilot randomised controlled trial aimed at evaluating the safety, tolerability and compliance with propolis in breast cancer patients receiving doxorubicin and cyclophosphamide, testing preliminary clinical efficacy of propolis in the prevention of OM, and prospectively evaluating the incidence of OM. Sixty patients were randomised to receive either a dry extract of propolis with 8%-12% of galangin plus mouth rinsing with sodium bicarbonate (experimental arm), or mouth rinsing with sodium bicarbonate (control arm). OM was evaluated with the NCI-CTCAE v4.0 after 5, 10, 15 and 21 days of treatment. Compliance with, tolerability of propolis and adverse events were recorded. The incidence of OM was also prospectively evaluated for 6 months. Two patients (6.7%) manifested a suspected skin reaction to propolis. No patient in the experimental arm developed OM > G1, while in the control arm OM > G1 was 16.7% (p = .02). The incidence of OM ≥ G1 at the end of cycles 2-8 was higher at the second (25%) and fifth cycles (45.8%). Propolis plus bicarbonate was safe, well tolerated and promisingly effective in the prevention of OM in patients with breast cancer.

RESUMO

We show how strong light-mediated resonant dipole-dipole interactions between atoms can be utilized in a control and storage of light. The method is based on a high-fidelity preparation of a collective atomic excitation in a single correlated subradiant eigenmode in a lattice. We demonstrate how a simple phenomenological model captures the qualitative features of the dynamics and sharp transmission resonances that may find applications in sensing.

RESUMO

BACKGROUND: Cervical spine instability is a clinical entity whose biomechanical and radiological features have been widely discussed by many authors. On the other hand, the subject of delayed post-traumatic cervical instability is often surrounded by confusion due to its difficult nosologic framing; the aim of this study is to contribute to the matter. METHODS: A cooperative study was organized by the Study Group for Spinal Surgery of the Italian Society of Neurosurgery to evaluate cervical trauma patients surgically treated more than 20 days after the traumatic event. From a total number of 172 patients, twenty-five were admitted to the study, because neuroradiological investigations performed during the acute phase had shown either an absence of traumatic lesions or only minimal lesions judged to be stable. For this reason these 25 patients had not been treated by either surgery or immobilization in a halo vest. Some time after trauma, this group of patients clearly demonstrated evidence of unstable lesions requiring surgical treatment, following the appearance of new clinical signs or on neuroradiological follow-up. RESULTS: Re-examination of the neuroradiological investigations performed during the acute phase made it possible to identify elements that might have led us to suspect the presence of ligamental lesions: microfractures, dislocations less than 3 mm, and inversion of physiological lordosis. CONCLUSIONS: This review clearly indicates that patients with even mild cervical trauma must be scrupulously evaluated during the acute phase and that in some cases it is advisable to perform a more detailed neuroradiological investigation.
