The purpose of this study was to investigate the effect of Treadmill Training on WISCI level, walking velocity, walking endurance, motor score and gait cycle of spinal cord injury patient with incomplete. Four subjects with spinal cord injury participated in this study. They took walking excercise 5 times per week for 8 weeks. One time excercise spent 30minutes. The theraputic effect was evaluated by WISCI level, walk 10 meters test, walk for 12 minutes test, motor score and gait cycle. Four subjects were examined before, after 8 week, walking training. Collected data were statistically analyzed by SPSS PC for Wilcoxon signed rank test. The results of this study are as follows; 1) In WISCI level, walking velocity, walking endurance and motor score, post - treatment score were higher compared to pre-treatment score with statistical significance(p<0.05). 2) In Rt SLS, DLSII and Lt SLS, post-treatment percentage were higher compared to pre-treatment percentage with statistical significance(p<0.05). but DLSI were not statistical significance(p>0.05). The findings suggest that spinal cord injury patients with incomplete can improve their WISCI level, walking velocity, walking endurance, motor score and gait cycle through Treadmill gait training.

One hundred and twenty patients with brain metastases were seen and evaluated in the Dept. of Therapeutic Radiology, Seoul National University Hospital between 1979 and 1983. Of these, 90 Patients received whole brain irradiation with 2,000 ra4 in 1 week or 3,000 rad in 2 weeks for Palliative Purpose and 30 patients failed to complete the planned treatment. Carcinoma of the lung(44 cases), choriocarcinoma(11 cases), breast(8 cases) were common Primary tumors of 90 patients receiving planned treatment. Symptomatic subjective response was obtained in $92\%$ of Patients and meurologic functional improvement was obtained in $42\%$ of patients. Median survival was 6.4 months in patients with complete treatment an·d less than 2 months in Patients with incomplete treatment, overall survival rate at 1 year and 2 year were $26\%,\;16\%$ in Patients with complete treatment and $8\%,\;0\%$ in patients with incomplete treatment. Primary site, extent of metastases and interval from diagnosis of primary tumor to brain metastases were identified as prognostic factors.

Observational data with missing or incomplete data are common in biomedical research. Multiple imputation is an effective approach to handle missing data with the ability to decrease bias while increasing statistical power and efficiency. In recent years propensity score (PS) matching has been increasingly used in observational studies to estimate treatment effect as it can reduce confounding due to measured baseline covariates. In this paper, we describe in detail approaches to competing risk analysis in the setting of incomplete observational data when using PS matching. First, we used multiple imputation to impute several missing variables simultaneously, then conducted propensity-score matching to match statin-exposed patients with those unexposed. Afterwards, we assessed the effect of statin exposure on the risk of heart failure-related hospitalizations or emergency visits by estimating both relative and absolute effects. Collectively, we provided a general methodological framework to assess treatment effect in incomplete observational data. In addition, we presented a practical approach to produce overall cumulative incidence function (CIF) based on estimates from multiple imputed and PS-matched samples.

This paper discusses how to use projections for the analysis of data from balanced incomplete block designs. A model is suggested as a matrix form for the interblock analysis. A second set of treatment effects can be found by projections from the suggested interblock model. The variance and covariance matrix of two estimated vectors of treatment effects is derived. The uncorrelation of two estimated vectors can be verified from their covaraince structure. The fitting constants method is employed for the calculation of block sum of squares adjusted for treatment effects.

We report a case of large radicular cyst progression related to endodontic origin to emphasize proper intervention and follow-up for endodontic pathosis. A 25 yr old man presented with an endodontically treated molar with radiolucency. He denied any intervention because of a lack of discomfort. Five years later, the patient returned. The previous periapical lesion had drastically enlarged and involved two adjacent teeth. Cystic lesion removal and apicoectomy were performed on the tooth. Histopathological analysis revealed that the lesion was an inflammatory radicular cyst. The patient did not report any discomfort except for moderate swelling 3 days after the surgical procedure. Although the patient had been asymptomatic, close follow-ups are critical to determine if any periapical lesions persist after root canal treatment.

Purpose: Endoscopic resection is widely accepted as standard treatment for early gastric cancer (EGC) without lymph node metastasis. The procedure is minimally invasive, safe, and convenient. However, surgery is sometimes needed after endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) due to perforation, bleeding, or incomplete resection. We evaluated the role of surgery after incomplete resection. Materials and Methods: We retrospectively studied 29 patients with gastric cancer who underwent a gastrectomy after incomplete EMR/ESD from 2006 to 2010 at Korea University Hospital. Results: There were 13 incomplete resection cases, seven bleeding cases, three metachronous lesion cases, three recurrence cases, two perforation cases, and one lymphatic invasion case. Among the incomplete resection cases, a positive vertical margin was found in 10, a positive lateral margin in two, and a positive vertical and lateral margin in one case. Most cases (9/13) were diagnosed as mucosal tumors by endoscopic ultrasonography, but only three cases were confirmed as mucosal tumors on final pathology. The positive residual tumor rate was two of 13. The lymph node metastasis rate was three of 13. All lymph node metastasis cases were submucosal tumors with positive lymphatic invasion and no residual tumor in the gastrectomy specimen. No cases of recurrence were observed after curative resection. Conclusions: A gastrectomy is required for patients with incomplete resection following EMR/ESD due to the risk of residual tumor and lymph node metastasis.

Purpose : This study is to see how much proportion of the patients receiving radiation therapy drop out during radiation therapy and to analyze the reason for the incomplete treatment. Materials and Methods : The base population of this study was 1,100 patients with registration numbers 901 through 2,000 at Department of Radiation Oncology, Samsung Medical Center, Seoul, Korea. Authors investigated the incidence of incomplete radiation therapy, which was defined as less than 95$\%$ of initially planned radiation dose, and the reasons for incomplete radiation therapy. Results : One hundred and twenty eight patients (12$\%$) did not complete the planned radiation therapy. The performance status of the incompletely treated patients was generally Poorer than that of the base population, and the aim of radiation therapy was more commonly palliative. The most common reason for not completing the planned treatment was the patients' refusal of further radiation therapy because of the distrust of radiation therapy and/or the poor economic status. Conclusion : Careful case selection for radiation therapy with consideration of the socioeconomic status of the patients in addition to the clinical indication would be necessary for the reduction of incomplete treatment, especially in the palliative setting.

Objective : This study is performed to evaluate the procedural complications, aneurysm occlusion rate, and mid-term outcome of endovascular treatments in intracranial aneurysms. Methods : We retrospectively investigated 135 patients with 161 cerebral aneurysms who were treated by endovascular means at our institute from March 1999 to December 2004. We statistically analyzed overall outcome, occlusion rate, and occurrence of complications according to the location, size, rupture history, and neck size of aneurysms. Results : Forty-nine patients [36.3%] had experienced acute intracranial or extracranial complications related to the procedure. Among these, there were 13cases of perforation of the aneurysm, 9 of local vasospasm, 8 of thromboembolism, 4 of coil migration, 3 of occlusion of parent vessels due to coil protrusion, and 1 of seizure. Extracranial complications occurred in 14cases including alopecia [9cases], femoral artery thrombosis [2cases], acute renal failure [2cases], and hypovolemic shock [1case]. One hundred twenty-six aneurysms [78.3%] had complete occlusion of the aneurysm and 35 [21.7%] incomplete occlusion at 6months angiographic follow-up. Postembolization clinical follow-up ranged from 1 to 60months [mean, 14.2months]. Seven of the 161 aneurysms underwent additional embolization and 2 incomplete embolized aneurysms required subsequent surgery. Conclusion : The procedural complications and incomplete occlusion rates are substantial. Therefore, endovascular treatment needs close and continued neurosurgical and neuroradiological concerns for the therapy of intracranial aneurysms.
