Debridement is a crucial component of wound management. Recent technologies such as hydrosurgery (Versajet), ultrasound therapy (the MIST therapy device), or plasma-mediated bipolar radio-frequency ablation therapy (Coblation) seem to represent interesting alternatives for wound debridement. The purpose of this systematic review was to describe, evaluate, and compare these three recently developed methods for the management of chronic wounds. In January 2016, an electronic database search was conducted of MEDLINE, PubMed Central, and Embase for articles concerning these three innovative methods for the management of chronic wounds. A total of 389 references were identified by our search strategy, and 15 articles were included. We extracted data regarding the number and age of patients, indications, operating time, number of procedures, costs, wound healing time, decrease in exudation, perioperative blood loss, bacterial load, and the occurrence of complications. The 15 articles included studies that involved 563 patients who underwent hydrosurgery (7 studies), ultrasound therapy (6 studies), or Coblation (2 studies). Six randomized controlled trials were included that compared the use of a scalpel or curette to hydrosurgery (2 studies) or ultrasound therapy (6 studies). Hydrosurgery, in addition to being a very precise and selective tool, allows significantly faster debridement. Ultrasound therapy provides a significant reduction of exudation, and improves the wound healing time. No comparative study dedicated to Coblation was identified. Despite the obvious clinical interest of the topic, our review of the current literature revealed a lack of prospective randomized studies comparing these devices with each other or with standard techniques, particularly for Coblation and hydrosurgery.

Objective : The authors conducted a retrospective study to evaluate the preservation rates of serviceable hearing and to determine its prognostic factors after gamma knife stereotactic radiosurgery[GK SRS] in the patient with vestibular schwannomas. Methods : Between December 1997 and March 2005, 54 patients with a sporadic vestibular schwannoma and serviceable hearing [Gardner Robertson grade I-II] were enrolled in this study. Electronic database of medical records and radiological examinations before and after GK SRS were investigated to the last follow up. The mean marginal dose was $12.3{\pm}0.7Gy$. The mean maximum dose delivered to the tumor center was 24.7Gy [$22{\sim}30Gy$]. The median tumor volume was 2cc [$0.1{\sim}9.1cc$]. The median follow-up period of magnetic resonance[MR] imaging was 31 months [$6{\sim}99\;months$], and the mean follow-up period of audiometry was 24 months [$4{\sim}70\;months$]. Results : The tumor control rate was 100% in the patients with the follow up period more than 2 years. The trigeminal and facial nerve preservation rates were 98% and 100%, respectively. Twenty-eight [52%] of the 54 patients preserved serviceable hearing and 16 [30%] patients retained their pre-GK G-R grade level after GK SRS. In the univariate and multivariate analysis, there was no significant prognostic factor in preservation of the serviceable hearing. Conclusion : The hearing preservation rate is still unsatisfactory compared with the results of other cranial nerve preservation and tumor control in the treatment of vestibular schwannoma by GK SRS. More sophisticated strategy during and after GK SRS is necessary to improve long-term hearing preservation.

The purpose of this study is to identify prognostic predictors of postoperative acute renal failure(ARF) for the patient undergoing cardiac surgery. Retrospectively review the electronic hospital database at a A hospital from Jan 2008 to Dec. 2011. 483 patients were included in this study. They were divided into a occurrence of ARF group(n=59) and a non occurrence of ARF group(n=424). ARF occurred in 59 cases (12.2%). Multi-variable logistic regression analysis identified that preoperative risk factors include creatinine(OR 3.92, p=<.001), advanced age(OR 2.142, p=.015), female(OR 2.165, p=.015), hypertension(OR 2.513, p=.005), NYHA(New York Heart Association) class II(OR 3.081, p=.003), and III(OR 6.759, p=.004), and intraoperative risk factor includes blood transfusion(OR 3.753, p=<.001), and postoperative factors include bilirubin(OR 4.541, p=.028), creatine(OR 8.554, p=.003), and cardiac output(OR 0.214, p=.033) as a prognostic predictors. The development of postoperative ARF could be a reason for increase in rate of complication and mortality after cardiac surgery. therefore the prevention of ARF is of paramount importance and treatment strategies are urgently needed.

Data mining plays an important role in knowledge discovery process and usually various existing algorithms are selected for the specific purpose of the mining. Currently, data mining techniques are actively to the statistics, business, electronic commerce, biology, and medical area and currently numerous algorithms are being researched and developed for these applications. However, in a long run, only a few algorithms, which are well-suited to specific applications with excellent performance in large database, will survive. So it is reasonable to focus our effort on those selected algorithms in the future. This paper classifies about 30 existing algorithms into 7 categories - association rule, clustering, neural network, decision tree, genetic algorithm, memory-based reasoning, and bayesian network. First of all, this work analyzes systematic hierarchy and characteristics of algorithms and we present 14 criteria for classifying the algorithms and the results based on this criteria. Finally, we propose the best algorithms among some comparable algorithms with different features and performances. The result of this paper can be used as a guideline for data mining researches as well as field applications of data mining.

Objectives: This research aimed to confirm the efficacy of oriental medicine in sixth cranial nerve palsy and to evaluate the quality of the studies. Methods: Using the medical subject heading (MeSH) keywords "abducens nerve palsy", "abducens nerve paralysis", "sixth nerve palsy", "herbal medicine", "Chinese medicine", "oriental medicine" and "acupuncture", we collected the research papers through an electronic database search in Oriental Medicine Advanced Searching Integrated System (OASIS), National Discovery for Science Leaders (NDSL), PubMed, Cochran Library, and China National Knowledge Infrastructure (CNKI). Results: A total of 136 papers were searched from the databases. Among these, 15 case reports and 8 randomized controlled trials (RCTs) met our criteria. 17 articles were found on the use of acupuncture as the main intervention, 11 on the use of herbal medicine as the main intervention, and 9 on the use of electroacupuncture as the main intervention. The frequently used acupoints were LI4, EX-HN5, GB1, BL2, TE23, LR3, BL1, ST2, GB20, and ST36. All 23 studies confirmed the efficacy of Korean medicine. According to the assessment using the risk of bias, the overall quality of the RCTs was low. Conclusions: Twenty-three papers suggested that Korean medicine treatment for abducens nerve palsy was effective in many cases. Analyzing the potential bias was difficult.
