Comparing oil based ointment versus standard practice for the treatment of moderate burns in Greece: a trial based cost effectiveness evaluation

<p>Abstract</p> <p>Background</p> <p>The local treatment of burn wounds has long been a subject of debate. The objective of this study was to compare the cost and the effectiveness of Moist Exposed Burn Ointment -MEBO versus a combination of <it>povidone iodine </it>plus <it>bepanthenol </it>cream for partial thickness burns.</p> <p>Methods</p> <p>The study was carried out in the Burn Center of a state hospital in Athens, Greece. 211 patients needing conservative therapy were prospectively selected according to the depth of the burn wound. The treatment was allocated according to the Stratified Randomization Design. The outcomes measured were mean cost of in-hospital stay, rate of complications, time of 50% wound healing, pain scores, in hospital stay diminution. We have adopted a societal perspective.</p> <p>Results</p> <p>In the total groups MEBO presented lower cost, (although not significantly different: p = 0.10) and better effectiveness. The data suggest that MEBO is the dominant therapy for superficial partial burn wound with significantly lower costs and significantly higher effectiveness due to a lesser time of recovery and consequently lower time of hospitalization and follow-up. MEBO presented similar percentages of complications with the comparator, lower pain levels and smaller time of no healthy appearance of the burn limits for superficial partial thickness burns.</p> <p>Conclusions</p> <p>The data suggested that topical application of MEBO may be considered for further investigation as a potential first-line treatment modality for superficial partial thickness burns.</p> <p>Trial registration</p> <p>The trial has been registered on the International Standard Randomised Controlled Trial Number Register (ISRCTN) and given the registration number <a href="http://www.controlled-trials.com/ISRCTN74058791">ISRCTN74058791</a>.</p

Multi-Sample Stochastic Filtering of OCT Skin Images

In order to suppress the noise due to chaotic scattering and improve the quality of the optical tomography image (OCT), we propose an improvement of our previous filter. The main idea of the new filter is based on the use of several images obtained by the OCT probing head from the same location on the skin surface. The efficiency of the multi-sample filtering algorithm is demonstrated on test examples and on real OCT images.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Original Article - The efficacy of moisture retentive ointment in the mangement of cutaneous wounds and ulcers: A multicenter clinical trial

Local management of chronic wounds and ulcers remains one of the most costly unsolved problems in health care today. With proper clinical management, most chronic wound healing problems can be resolved and healing expected, though recurrence may be common. The recent logarithmic growth in our knowledge about wound healing and the appreciation of the importance of a moist environment in optimal wound healing has led to the introduction of new and exciting therapeutic modalities. In view of the many practical disadvantages as well as the serious complications of currently available moisture retentive dressings when applied to chronic contaminated wounds, a prospective multicenter clinical trial was conducted from December 1999 to November 2000 to evaluate the safety and efficacy of a newly introduced moisture retentive ointment (MEBO: Moist Exposed Burn Ointment) (Julphar – Gulf Pharmaceutical Industries, UAE) in the local wound care of problematic non-healing wounds. The active component of the ointment is ß-sitosterol in a base of beeswax, sesame oil and other components. Though it was not a comparative study, the ointment was found to induce rapid reduction in ulcer size even after a prolonged stagnant state with other therapeutic modalities without complications such as skin maceration, unmanageable excessive exudation, and wound infection. As expected with such chronic wounds, the healing potential of local ointment application is limited by the mere size of the original defect and the underlying pathologies and associated diseases. however, the safety and practicality of simple ointment application was found to be a valid alternative treatment for local management of chronic wounds

Effect of genetically modified Schwann cells with increased motility in end-to-side nerve grafting

International audienceTaking into account that Schwann-cell (SC) motility is a prerequisite for myelination during peripheral nerve regeneration, the present study was designed with the intention to increase SC motility in vitro and to evaluate the effect of transduced SC on nerve regeneration in vivo, through silicone tubes after end-to-side nerve repair. Our in vitro study demonstrated that SC transduction with the pREV-HW3 retrovirus, encoding for sialyl-transferase-X (STX), significantly increased their motility compared to the control. In the in vivo study, 45 Wistar rats were randomized into three groups of 15 each. In all animals, the left peroneal nerve was severed, and a 10-mm segment was removed. The distal stump of the peroneal nerve was connected end-to-side to a perineurial window in the ipsilateral tibial nerve with either a silicone tube lined with SC (group A) or a silicone tube lined with STX-transduced SC (groups B and C). Fluorescence and light microscopy in group C showed that SCs were viable the first critical 15 postoperative days. After 90 days, light microscopy in group B demonstrated that STX-transduced SCs with increased motility ensured nerve regeneration, through silicone tubes, in all cases. Furthermore, STX-transduced SCs increased significantly fiber diameter and myelin thickness, and most importantly enhanced significantly the functional outcome compared to nontransduce

Randomized Phase III Study of 1 Month Versus 1 Year of Adjuvant High-Dose Interferon Alfa-2b in Patients With Resected High-Risk Melanoma

Purpose A high-dose interferon alfa (IFN-alpha) regimen as reported in E1684 was unique for the incorporation of an induction phase of maximally tolerated dosages of intravenous (IV) therapy for the initial 4 weeks. This is the only trial that has shown prolongation of overall survival and relapse-free survival (RFS) in comparison with observation. Analysis of the hazard curves for RFS and overall survival (OS) in E1684 revealed separation of the high-dose and observation arms, suggesting that the induction phase may represent a critical component of this regimen, although this has not been tested prospectively. Patients and Methods We conducted a prospective randomized study of IV induction therapy versus a full year of high-dose IFN, with primary end points of RFS and OS for patients with stage IIB, IIC, and III melanoma, within 56 days of curative surgery. Patients were randomly assigned to receive IFN-alpha-2b 15 x 10(6) U/m(2) IV x 5/7 days weekly x 4 weeks (arm A) versus the same regimen followed by IFN-alpha-2b 10 x 10(6) U (flat dose) administered subcutaneously three times a week for 48 weeks (arm B). Results Between 1998 and 2004, 364 patients were enrolled (353 eligible: arm A, n = 177; arm B, n = 176). At a median follow-up of 63 months (95% CI, 58.1 to 67.7), the median RFS was 24.1 months versus 27.9 months (P = .9) and the median OS was 64.4 months versus 65.3 months (P = .49). Patients in arm B had more grade 1 to 2 hepatotoxicity, nausea/vomiting, alopecia, and neurologic toxicity. Conclusion There were no significant differences in OS and RFS between the regimens of 1 month and 1 year of treatment
