Anaplastic thyroid cancer is a rare disease entity consist 2% of whole thyroid cancer but once diagnosed, it is too fatal to survive. Airway obstruction is a leading cause of death in anaplastic thyroid cancer, which may be caused by both vocal cord palsy, mass effect of the cancer or direct invasion of the cancer itself to the tracheal lumen. Tracheal stent insertion can be a solution for airway compromised cases where surgical excision cannot be performed. The advantage is that the airway problem can be solved without invasive procedure. In this case, we tried expandable tracheal stent insertion for 66 years-old man with anaplastic cancer who visited ER for small amount of hemoptysis and dyspnea. There was severe tracheal narrowing and deviation due to the anaplastic thyroid cancer, ECMO (Extra Corporal Membrane Oxygenation) was used instead of a tracheal intubation for general anesthesia.

Objectives : The aim of this study is to suggest approach of oriental medical management and necessity by research of eastern and western medical literatures for Complex Regional Pain Syndrome(CRPS). Methods : We reviewed the clinical and experimental literatures of eastern and western concerned with CRPS which is related causation, signs and symptoms, diagnosis, etiology and management. Results : 1. CRPS is divided into type I and II by nerve injury. Two types of CRPS have been recognized: type I, corresponds to RSD and occurs without a definable nerve lesion, and type II, formerly called causalgia refers to cases where a definable nerve lesion is present. These conditions can be charaterized clinically by the sensory abnormalities, vascular abnormalities, oedema, sweating abnormalities, motor or trophic changes. 2. CRPS are well known to patients and physicians relatively, but the pathophysiology, causation and treatments are still unclear. 3. CRPS is needed to take the early diagnosis and multidisciplinary approach for significant effect. 4. CRPS can be regarded for obstruction syndrome of Ki and blood(痺證), blood stasis(瘀血), Wei symptom(痿證), numbness(痲木) in the oriental medical management of CRPS. Conclusions : Above the results, it is suggested that further studies and active approach of management of CRPS will be conducted precisely in oriental medicine.

Uterine cervical cancer is the most common malignancy in korean women. In spite of recent development of early diagnostic and therapeutic modalities, about 40% of treated patient will develop relapse. So more aggressive local treatment such as more extensive surgery and higher radiation dose and administration of systemic chemotherapy will promote the curability but treatment related complications can not be avoidable. We used 22 cases of early cervical cancer, treated with surgery and post-operative radiotherapy, clinical data of these patients were analized to determine relationship between clinical parameters and final outcome. Three out of 22 cases revealed relapse and one patient showed rectovaginal fistula and another patient showed small bowel obstruction and the other patient showed rectal obstruction. Two out of three recurrence were stage IIa and the other one case was stage Ib adenocarcinoma with lymphovascular involvement. Nineteen out of 22 cases were followed without remarkable side effect or treatment related complication or sequelae. We concluded that our treatment policy was safe and effective to eradicate high risk postoperative cervical cancer with acceptable side effects or complication.

Background/Aims: Coaxial placement of double pigtail plastic stents (DPPS) through lumen-apposing metal stents (LAMSs) is commonly performed to reduce the risk of LAMS obstruction, bleeding, and stent migration when used for the drainage of pancreatic fluid collections (PFCs). A systematic review and meta-analysis were performed to compare the outcomes of LAMS alone and LAMS with coaxial DPPS placement in the management of PFCs. Methods: A systematic review was conducted to identify studies comparing LAMS and LAMS/DPPS for PFC drainage. Primary outcomes included the rate of clinical success, overall adverse events (AEs), bleeding, infection, occlusion, and stent migration. The pooled effect size was summarized using a random-effects model and compared between LAMS and LAMS/DPPS by calculating odds ratios (ORs). Results: Nine studies involving 709 patients were identified (338 on LAMS and 371 on LAMS/DPPS). LAMS/DPPS was associated with a reduced risk of stent obstruction (OR, 0.59; p=0.004) and infection (OR, 0.55; p=0.001). No significant differences were observed in clinical success (OR, 0.96; p=0.440), overall AEs (OR, 0.57; p=0.060), bleeding (OR, 0.61; p=0.120), or stent migration (OR, 1.03; p=0.480). Conclusions: Coaxial DPPS for LAMS drainage of PFCs is associated with a reduced risk of stent occlusion and infection; however, no difference was observed in the overall AE rates or bleeding.

Objectives: The purpose of this study is to investigate the effect of traditional Korean medical treatment; acupuncture and herb therapy in pediatric allergic rhinitis patients. Methods: This study population was 69 pediatric allergic rhinitis patients who had been treated in ${\bigcirc\bigcirc}$ hospital. All the patients were asked to answer the questionnaires that consist of 10 questions about symptoms of allergic rhinitis. Results: 1. The total scores from the same questionnaire about allergic rhinitis symptoms were significantly improved after the treatment compared to the scores before the treatment(p<0.01). 2. The Nasal symptom, especially, nasal obstruction rhinorrhea had significantly improved in all groups of patients(p<0.01). 3. The effect of the treatment was better with spending more time with acupuncture. Conclusions: Traditional Korean medical treatment is relatively effective in treating pediatric allergic rhinitis.

Objectives : This study was aimed to investigated the effect of Yijin-tang on gastric motility and its mechanism of action in normal intact and partial pyloric obstructed rats. Methods : Gastric emptying was measured by the number of glass beads expelled from the stomach (containing one hundred of glass beads. ${\phi}1mm$) in 1 hour or 2 hours after glass beads and test drugs (normal saline. Yijin-tang 90mg/kg. Yijin-tang 270mg/kg) administration in normal intact and partial pyloric obstructed rats. In another series of experiments to evaluate the mechanism of Yijin-tang 270mg/kg under delayed conditions, normal intact rats were treated with atropine sulfate (1mg/kg,s.c.), cisplatin (10mg/kg,i.p.), quinpirole HCI (0.3mg/kg,i.p.) and NAME (NG-nitro-L-arginine methyl ester. 75mg/ kg,s.c.), respectively. Partial pyloric obstructed rats were modified by wrapping the nonabsorbable rubber ring (D :6mm, W:4mm, T: 1mm) around the 1st portion of the duodenum for 8 weeks. The myoelectrical activity of the gastric smooth muscle was recorded by a bipolar electrode placed at the abdominal surface in normal intact and partial pyloric obstructed rats. The gastric myoelectrical activity was measured for 30 minutes before and after orogastric administration of each solution (normal saline, Yijin-tang 270mg/kg) and expressed as dominant frequency, percent of normogastria and power ratio. Results : Yijin-tang improved gastric emptying more than normal saline in normal intact(p<0.001) and partial pyloric obstructed rats(p=0.002). Under the delayed gastric emptying induced by atropine sulfate, cisplatin, quinpirole HCI and NAME. Yijin-tang enhanced gastric emptying significantly in the cisplatin treated group(p<0.001). but didn't in other treated groups. Administration of Yijin-tang 270mg/kg has no significant effect on the myoelectrical activity of the gastric smooth muscle in both normal intact rats and partial pyloric obstructed rats. Conclusions : Yijin-tang seems to stimulate the gastric motility through suppressing the 5HT3 receptor and promoting the antroduodenal flow. We expect that Yijin-tang would be effective especially in dysmotility-like functional dyspepsia with partial pyloric obstruction or the side effects of cisplatin such as nausea, vomiting, abdominal discomfort, and delay of gastric emptying.

Here, A forty year old patient is presented, showing azoospermia following vasovasostomy. The bilateral testicular biopsies were performed to confirm whether ductal obstruction due to vasovasostomy or testicular failure existed. The finding of biopsy was spermatogenic arrest. After completion of medical testicular stimulation with clomiphene citrate and pentoxifilline for 3 months, repeat vasovasostomy was performed. Semenanaylsis revealed normal sperm parameters after operation. Necessity of testicular biopsy before deciding repeat vasovasostomy, accuracy of testicular biopsy, efficacy of testicular stimulation in the patient with spermatogenic arrest and effect of testicular biopsy on testicular fuction are discussed.

From the viewpoint of the structural design, the principal problem of the heat exchanger is the potentiality of structural instabilities due to the fluid loading effect during operations. Excessive fluid loading may give rise to permanent deformation of tube and would enentually result in collapse of heat exchanger, which would cause an obstruction of the fluid flow in the narrow channels. In this study, a fluid-structural interaction model was developed to investigate analtically the vibration characteristics of thin rectangular tube used in the heat exchanger. The model consists of two flat plates separated by fluid. The effects of the fluid in the tube was stuided. For analyses, the natural frequency coefficients of the model were investigated for the plate aspect ratios, channel heights, and boundary conditions. As conclusions, the natural frequency coefficients of the tube is found to be affected largely by the fluid loading and the channel heights.

Intussusception is common cause of intestinal obstruction in children. Most of intussusceptions can be treated with non-operative reduction using air or barium. However, about 10% patients need operative treatment due to failure of reduction, peritonitis, and recurrence after reduction. We introduce our experience of laparoscopic surgery for intussusception. From April 2010 to March 2013, we reviewed 57 children who diagnosed intussusception. Twelve patients underwent an operation. The cause of operation was 7 of failure of air reduction and 5 of recurrence after air reduction. Median age was 21.5 months (range: 5.0~57.7 months) and 11 children (91.7%) underwent successful laparoscopic reduction. Median operating time was 50 minutes (range: 30~20 minutes) and median hospital days was 4.5 days (range: 3~8 days). One patient had a leading point as a heterotopic pancreas and underwent bowel resection through conversion. There was neither intra-operative nor postoperative complication. Laparoscopic reduction for intussusception can bring an excellent cosmetic effect with high success rate.
