Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased form 109mOsmol/Kg to 327mOsmol/Kg (300%). Brain MRI showed a thickened pituitary stalk and at hot bone CT.CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes, The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.

<B>Objective:</B><P>This study was performed to evaluate the efficacy and feasibility of electrosurgical conization and cold coagulation as definitive treatments for patients with International Federation of Gynecology and Obstetrics stage IA1 squamous cell carcinoma of the cervix and a resection margin free from (micro)invasive carcinoma after conization.</P><B>Methods:</B><P>Patients with stage IA1 cervical squamous cell carcinoma without lymphovascular space invasion who had been treated by electrosurgical conization and cold coagulation and who wanted to preserve fertility (or only undertake conservative treatment) were followed up without further surgical intervention. Patients with invasive or microinvasive carcinoma at resection margins or positive endocervical resection margins were excluded from the study. Cervicovaginal smears and colposcopic examination were performed at regular intervals. Disease recurrence was defined as a histologic diagnosis of cervical intraepithelial neoplasia 2 or higher-grade lesions.</P><B>Results:</B><P>A total of 85 patients enrolled were deemed eligible to be involved in the study. The median follow-up period was 81.0 months (range, 13-127 months). Nineteen of the 85 patients had exocervical resection margins. There was one case of recurrence, which was node-positive invasive cancer recurrence (1.2%, 1/85), in patients with negative resection margins.</P><B>Conclusions:</B><P>These results suggest that electrosurgical conization with cold coagulation is a feasible treatment and could be used as a definitive therapy for patients with stage IA1 cervical squamous cell carcinoma without lymphovascular space invasion. In addition, patients having cervical intraepithelial neoplasias 2 and 3 at exocervical resection margins could be followed up carefully without further treatment after conization and cold coagulation.</P>

<P>A micro-alloyed non-heat-treated material does not need post heat treatment processes such as quenching and tempering after the forming process in production stages. This material can be called a green material since it can reduce industrial costs and harmful pollutants generated from post heat treatments. In this paper, near-net-shape forming processes were studied in order to make an automotive part using a micro-alloyed material. The cold forging technique using a former was utilized for the main shaping, and the cold incremental forming technique using a cross wedge rolling machine was adopted for the enhancement of strength and the final shaping of the part. In order to get more adequate process, the cross wedge rolling process is compared to the swaging process for the micro-alloyed steel and general carbon steels through experiments.</P>

<P>Background: Cytomegalovirus (CMV) colitis can contribute to an unfavorable outcome of acute severe ulcerative colitis (ASUC). The purpose of this study was to evaluate the clinical outcomes of ASUC according to the CMV status and identify risk factors for CMV colitis in patients with ASUC. Methods: We retrospectively analyzed patients with ASUC from 2011 to 2014 according to the criteria of Truelove and Witts. CMV colitis was diagnosed by histopathological and/or immunohistochemical analysis of tissue samples. The risk factors for CMV colitis were investigated and clinical outcomes were assessed using the rate of rescue therapy and colectomy. Results: Of 149 patients with ASUC, 50 (33.6%) were diagnosed with CMV colitis. During admission, 16 of 149 patients (10.7%) underwent colectomy: 7 of 50 (14.0%) in the ASUC-CMV group versus 9 of 99 (9.1%) in the ASUC-only group (P = 0.364). The need for rescue therapy was 2.28-fold higher in the ASUC-CMV group than in the ASUC-only group in multivariate analysis (95% confidence interval, 1.10-4.72). Multivariate analysis also revealed that recent use of high-dose steroids (odds ratio, 3.30; 95% confidence interval, 1.33-8.19) and a higher Mayo score (odds ratio, 1.58; 95% confidence interval, 1.05-2.38) were risk factors for CMV colitis. Conclusions: CMV colitis often occurs in ASUC, particularly in patients who have recently been treated with high-dose steroids and have a higher Mayo score on admission. Patients with ASUC and CMV colitis seem to have a poorer prognosis, as indicated by the greater need for rescue therapy.</P>

<P>Abstract</P><P><B><I>Aim:</I></B> To evaluate prognostic factors in Korean patients with endometrial cancer. <B><I>Methods:</I></B> A retrospective analysis was conducted on 248 patients who were staged surgically at the Samsung Medical Center between 1995 and 2004. Survival data were analyzed using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression method. <B><I>Results:</I></B> The median age was 51 years (range 21–75), which was younger than in previous studies in Western patients, and the age of 50 years was the cutoff to predict survival. More than half (55.6%) were normal weight or underweight (BMI <25). Multivariate analysis revealed that age, Fédération Internationale de Gynécologie et d’Obstétrique (FIGO) stage, and histopathology were independent predictors of disease-free survival, and FIGO stage and p53 mutation were independent prognostic factors for disease-specific survival (DSS). The 5-year DSS for patients with stage I, II, III and IV disease was 95.6, 93.8, 69.8 and 50%, respectively. The 5-year DSS rate for patients with a p53 mutation was 84.4%, compared with 97.1% for patients without. <B><I>Conclusions:</I></B> Korean patients with endometrial cancer were younger and had a lower BMI than previously reported. Furthermore, age greater than 50 years was predictive of a poor outcome. Age, FIGO stage, histopathology and a p53 mutation were independent prognostic factors for survival.</P><P>Copyright © 2012 S.

<P>We studied the efficacy and safety of acarbose in comparison with voglibose in type 2 diabetes patients whose blood glucose levels were inadequately controlled with basal insulin alone or in combination with metformin (or a sulfonylurea). This study was a 24-week prospective, open-label, randomized, active-controlled multi-center study. Participants were randomized to receive either acarbose (n=59, 300 mg/day) or voglibose (n=62, 0.9 mg/day). The mean HbA<SUB>1c</SUB> at week 24 was significantly decreased approximately 0.7% from baseline in both acarbose (from 8.43% ± 0.71% to 7.71% ± 0.93%) and voglibose groups (from 8.38% ± 0.73% to 7.68% ± 0.94%). The mean fasting plasma glucose level and self-monitoring of blood glucose data from 1 hr before and after each meal were significantly decreased at week 24 in comparison to baseline in both groups. The levels 1 hr after dinner at week 24 were significantly decreased in the acarbose group (from 233.54 ± 69.38 to 176.80 ± 46.63 mg/dL) compared with the voglibose group (from 224.18 ± 70.07 to 193.01 ± 55.39 mg/dL). In conclusion, both acarbose and voglibose are efficacious and safe in patients with type 2 diabetes who are inadequately controlled with basal insulin. (ClinicalTrials.gov number, NCT00970528)</P>

본 논문에서는 연소 성능이 다른 이종의 열가소성 추진제를 적용하고 부스터와 서스테이너의 연소표면적을 다르게 하여 각각의 요구 추력이 발생하도록 하는 이중추력 프로파일을 갖는 추진기관을 개발하고 그 개발과정을 기술하였다. 개발한 추진기관은 크게 연소관, 추진제 그레인, 노즐, 토출관으로 구성되며 지상연소시험을 통해 성능을 검증하였다. 개발한 추진기관은 지상연소시험 결과, 부스터와 서스테이너의 추력비는 약 14:1, 총 역적 편차는 2% 이내의 성능을 보였다. This paper describes the development process of dual thrust rocket motor which is developed by LIGNEX1. The motor was realized by using two types of thermoplastic propellants whose burning rates and the area of burning surfaces are different from one another. The developed motor consisted of combution chamber, propellant grain, nozzle and blast tube and its performance were investigated by conducting several ground tests. The test results showed that thrust ratio of booster and sustainer was 14:1 and the deviation of total impulse was below 2%.
