Hyperreactio luteinalis is a rare disease characterized by marked cystic enlargement of the ovary due to multiple benign theca lutein cyst. The cause of this disease is not well known but is believed to be induced by high serum levels of human chorionic gonadotropins (hCG). It occurs usually in gestational trophoblastic disease, multiple pregnancies, and rarely in normal pregnancy. In nature, hyperreactio luteinalis is a benign condition. Therefore, the appropriate management is conservative, but surgical intervention is definitely indicated to remove infarcted tissue, control hemorrhage, or decrease androgen production in virilized patients. Here we report a case of hyperreactio luteinalis which was diagnosed at 11 weeks gestation. Lower abdominal pain was developed and progressed. Emergent right wedge oophorectomy and left salpingoophorectomy was performed due to probable torsion of left ovarian cyst and the pregnancy maintained. Theca lutein cysts were confirmed on pathologic examination.

MRI(Magnetic Resonance Imaging) have provided for greater image resolution, detailed tissue contrast without use of contrast media and images acquired in any plane. The purpose of this study was to examine the anatomy and dimension of the epidural space using MRI(Magnetic Resonance Imaging) and to compare the information obtained with that from other investigative technique. The anatomy of the lumbar epidural space was studied retrospectively using lumbar MRI scans of 90 patients. The epidural width(E.W.) is divided into three distance between the anterior surface of the ligamentum flavum and the dura at the caudal end of the lumbar segment(A), at the mid point of the ligamentum flavum(B) and at the cranial end of the lumbar segment(C). The distance from skin to supraspinous ligament(S-L) and from supraspinous ligament to epidural space(L-E) were measured. And then with adding both the distance, We measured the distance from skin to epidural space(S-E). Results were as follows; I) Posterior to the dural sac, epidural fat which is of high signal(white) on Tlw(T1 weighted) image is demonstrated at levels Tl I-T12 to L5-Sl giving 'Saw toothed' pattem to the epidural space. The fat is divided into segments by the interposing laminar, and the epidural space is deeper at cranial end than caudal end. 2) It was the relatively wide epidural space in L2-3 and L3-4 level, and the narrowest epidural space in L5-Sl level. 3) The distance from skin to supraspinous ligament was noted marked variation(2-40mm) according to the individual disparity. And the distance from supraspinous ligament to epidural space is 17-43mm. In distance from skin to epidural space, the most narrow place is Ll-21evel (37.95+/-7.65mm). The most deep place is IA-5 level(46.35+/-7.20mm). As the age increase, epidural width is decreased at L3-4 level (p<0.05).

The purpose of this study was to evaluate the effect of immediate or delayed composite resin filling on dentinal microtensile bond strength (microTBS) after applied the adhesive. The coronal dentin of human third molars was exposed. Single-Bond or One-Step was applied on the dentin surfaces, and composite resin were constructed immediately (group 1) or 5 min., 10 min., 15 min., 20 min. and 30 min. (groups 2-6) after an adhesive was applied. The specimens were sectioned and made bar-shaped. Each surface area of them was about 1mm2. The microTBS test was performed by EZ test. The results were analysed by One-way ANOVA and Tukey's test at 95% significance level. The results suggested that the microTBS of Single-Bond to dentin was decreased when the composite resin was constructed 20 min. and 30 min. after Single-Bond was applied. But the microTBS of One-Step was not affected by delayed composite resin filling.

Vascular injury caused by a central venous catheter (CVC) has been reported to be a rare complication, especially delayed vascular injury due to CVC has a few cases and it can be fatal because of delayed recognition and more serious complications. A 59-year-old woman with no available medical history was admitted for treatment of ovarian cancer. For the surgery, a triple-lumen CVC was placed through the left subclavian vein. Parenteral nutrition through the CVC was used for postoperative nutritional management in the first postoperative day. On the sixth postoperative day (POD), the patient suddenly complained of dyspnea. The CT revealed bilateral pleural effusion and irregular soft tissue density and air bubble in anterior mediastinum suggesting migration of the distal portion of the CVC into the anterior mediastium. In the intensive care unit (ICU) bilateral thoracentesis and percutaneous drainage were performed. She was discharged from the ICU in 3 days later and transferred to the general ward. This case emphasizes the possibility of the delayed vascular injury related to CVC and some strategies for prevention of vascular injury.

Hantavirus pulmonary syndrome(HPS) is a systemic disease that is caused by a newly discorved and characterized virus of the Hantavirus genus, which is most frequently referred to as the sin nombre virus. The clinical syndrome resembles other hantavirus syndromes worldwide, except that it is characterized by a brief prodromal illness followed by rapidly progressive, noncardiogenic edema, and that it is more deadly than any previously recognized hantavirus infection. The clinical manifestations of HPS are characterized by four clinical phases prodrome, pulmonary edema and shock, diuresis, and convalescence. Mortality is greatest in the first 24 hours of the pulmonary edema and shock phase of the illness. These phases are strikingly similar to the clinical phases of Hemorrhagic fever with renal syndrome(HFRS) induced by Hantaan virus, except that HPS has not been associated with renal failure and Disseminated intravascular coagulation(DIC). We here report a case of hantavirus pulmonary syndrome developed in a 58 year-old man. He had a flu-like illness followed by the rapid onset of respiratory failure due to noncardiogenic pulmonary edema. HPS was diagnosed by clinical manifestations, identification of high titer antibody to Hantaan virus antigen and histologic finding of transbronchial lung biopsy (TBLB) specimen. The patient was treated with mechanical ventilation and initial corticosteroid pulse therapy resulting in successful outcome.

In microarray technology, many diverse experimental features can cause biases including RNA sources, microarray production or different platforms, diverse sample processing and various experiment protocols. These systematic effects cause a substantial obstacle in the analysis of microarray data. When such data sets derived from different experimental processes were used, the analysis result was almost inconsistent and it is not reliable. Therefore, one of the most pressing challenges in the microarray field is how to combine data that comes from two different groups. As the novel trial to integrate two data sets with batch effect, we simply applied standardization to microarray data before the significant gene selection. In the gene selection step, we used new defined measure that considers the distance between a gene and an ideal gene as well as the between-slide and within-slide variations. Also we discussed the association of biological functions and different expression patterns in selected discriminative gene set. As a result, we could confirm that batch effect was minimized by standardization and the selected genes from the standardized data included various expression pattems and the significant biological functions.
