This paper describes the evaluation method of the gait motion in walk rehabilitation. We assume that the evaluation consists of the classification of the measured data and the prediction of the feature of the gait motion. The method may enable a doctor and a physical therapist to recognize the condition of the patients more easily, and increase the motivation of patient further for rehabilitation. However, it is difficult to divide the gait motion into discrete categories, since the gait motion continuously changes and does not have the clear boundaries. Therefore, the self-organizing map （SOM） that is able to arrange the continuous data on the almost continuous map is employed in order to classify them. And, the feature of the gait motion is predicted by the classification. In this study, we adopt the gravity-center fluctuation （GCF） on the sole as the measured data. First, it is shown that the pattern of the CCF that is obtained by our developed measurement system includes the feature of the gait motion. Secondly, the relation between the pattern of the GCF and the feature of the gait motion that the doctor and the physical therapist evaluate by visual inspection is considered using the SOM. Next, we describe the prediction of following features measured by numerical values： the length of stride, the velocity of walk and the difference of steps that are important for the doctor and the physical therapist to make a diagnosis of the condition of the gait motion in walk rehabilitation. Finally, it is investigated that the position of a new test data that is arranged on the map accords with the prediction. As a consequence, we confirm that the method using the SOM is often useful to classify and predict the condition of the patient.

Radiofrequency Ablation-Associated Delayed Diaphragmatic Hernia Treated with the Thoracolaparotomy Approach: A Case Report

引用

Case Reports in Clinical Medicine 2016年第12期5卷 541-547页

Background: Radiofrequency ablation (RFA) is an effective treatment for hepatocellular carcinoma (HCC). However, rare but serious complications may occur after RFA. We describe a case of diaphragmatic hernia associated with RFA. Case Presentation: A 68-year-old man with a history of hepatitis C-related liver cirrhosis was admitted to our hospital because of lower abdominal pain. Three years earlier, he underwent RFA for HCC in segment 8. Computed tomography revealed that the intestine was intruding into the right thoracic cavity through a diaphragmatic hernia. On the basis of the diagnosis of right diaphragmatic hernia with a strangulated ileus, an emergency operation was performed. Perforation of the strangulated transverse colon into the right thoracic cavity was suspected, and a combined approach of laparotomy and thoracotomy was utilized. The operative findings showed that the diaphragmatic hernia was 3.5 × 2.0 cm in diameter, and it was simply sutured with a nonabsorbable suture material. Resection of the intruded ischemic transverse colon was completed, and a covering ileostomy was performed. The patient was discharged without any complications. Conclusions: RFA is widely used for the treatment of HCC. Reports of early- and late-phase complications indicate that heat damage contributes to the fragility of neighboring organs. The occurrence of diaphragmatic hernia after RFA is one of the delayed complications. Although it rarely occurs, this complication requires emergency surgery. In conclusion, if perforation of the intestine into the thoracic cavity is suspected, thoracolaparotomy should be considered as a treatment option to prevent postoperative massive empyema.

Recently, the incidence of Candida infections has substantially increased. Conventional identification methods for Candida species are technically difficult to conduct and cannot accurately distinguish each species. The purpose of the present study was to design primers to identify and detect simultaneously eight medically important Candida species using one-step multiplex PCR. PCR primers were designed based on partial sequences of intergenic spacer (IGS) and internal transcribed spacer (ITS) genes of eight medically important Candida species. These primers were able to distinguish each Candida species and did not display cross-reactivity with representative Candida species other than the eight Candida species. Moreover, our developed one-step multiplex PCR method is accurate, specific, cost-effective, time-saving, and worked without requiring DNA extraction.

Standardized technique for single-incision laparoscopicassisted stoma creation

引用

World Journal of Gastrointestinal Endoscopy 2016年第15期8卷 541-545页

To describe the procedure, efficacy, and utility of singleincision laparoscopic-assisted stoma creation(SILStoma) for transverse colostomy. Using single-incision laparoscopic surgery, we developed a standardized technique for SILStoma. Twelve consecutive patients underwent SILStoma for transverse colostomy at Osaka Medical Center for Cancer and Cardiovascular Diseases from April 2013 to March 2016. A single, intended stoma site was created with a 2.5-3.5 cm skin incision for primary access to the intra-abdominal space, and it functioned as the main port through which multi-trocars were placed. Clinical and operative factors and postoperative outcomes were evaluated. Patient demographics, including age, gender, body mass index, and surgical indications for intestinal diversion were evaluated. SILStoma was performed in nine cases without the requirement of additional ports. In the remaining three cases, 1-2 additional 5-mm ports were required for mobilization of the transverse colon and safe dissection of abdominal adhesions. No cases required conversion to open surgery. In all cases, SILStoma was completed at the initial stoma site marked preoperatively. No intraoperative or postoperative complications greater than Grade Ⅱ(the Clavien-Dindo classification) were reported in the complication survey. Surgical site infection at stoma sites was observed in four cases; however, surgical interventions were not required and all infectionswere cured completely. In all cases, the resumption of bowel movements was observed between postoperative days 1 and 2. SILStoma for transverse loop colostomy represents a feasible surgical procedure that allows the creation of a stoma at the preoperatively marked site without any additional large skin incisions.
