The Tempofilter II is a widely used temporary vena cava filter. Its unique design, which includes a long tethering catheter with a subcutaneous anchor, facilitates the deployment and retrieval of the device. Despite this, the Tempofilter II has been used only in the inferior vena cava of patients with lower extremity deep venous thrombosis. In this article, we present a case of superior vena cava filtering using the Tempofilter II in patients with upper extremity deep venous thrombosis.

OBJECTIVE: To compare the clinical outcomes of patients with vitrified-thawed embryos transferred using either the 0.25 mL straw method and the pull and cut straw (PNC) method. To evaluate the clinical outcomes of patients with transferred embryos that underwent assisted hatching at the cleaved embryo (day 3) or the blastocyst (day 5) stage. METHODS: The study population consisted of women who underwent vitrified-warmed embryo transfer between May 2000 and December 2011 and assisted hatching was performed after warming of embryos. Cycles of thawing between assisted hatching treated and non treated groups were compared for survival and pregnancy rates. RESULTS: The PNC vitrification method improved survival and pregnancy rates in partial lysed embryos. While assisted hatching did not affect the developmental and clinical pregnancy rates of the vitrified-warmed blastocyst group, it did increase the pregnancy rate of poor quality vitrified-warmed cleaved embryos. CONCLUSION: These results suggest that PNC may increase the number of clinical pregnancies via the vitrification of both cleaved embryos and blastocysts. In addition, selective assisted hatching treatment of embryos that show a poor prognosis after warming may increase the rate of clinical pregnancy.

Glass Fiber is manufactured from typical glass-making raw materials, silicon dioxide with various metals and other elements. There are three distinct types of commercial glass fiber products: glass wool, an entangled mass of interlocking fibers; continuous glass filament, a product with a more ordered arrangement of fibers; and special-purpose glass fiber, a small-diameter fiber (less than 3 um) . We report a case of glass fiber-induced health hazard due to continuous glass filament from fiber reinforced plastics (FRF) as car interior material. A 40 years old man complained a sudden onset of severe itching on whole body, especially neck and forearms while driving a new car. He also complained burning of eyes, sore throat and productive cough. We diagnosed the glass fiver-induced skin lesion by placing skin scraping on a slide glass and examining the specimen under a microscope. We found same fibers from the air samples in the car and from the material of the interior surface of the car by the microscopic examination. Therefore we confirmed that the patient's symptoms and signs were induced by glass fiber.

PURPOSE: We wanted to describe the MR imaging findings of endometrial cancer in patients with a history of prior radiation therapy for cervical cancer (ECRT) and we compare them to the MR imaging findings of patients with spontaneously occurring endometrial cancer (SEC). MATERIALS AND METHODS: Twenty-two patients with endometrial cancer that was diagnosed by operation or endometrial biopsy were included in the study. The patients were divided into two groups according to the presence of past RT for cervical cancer: ECRT (n = 4) and SEC (n = 18). The MR images were retrospectively analyzed by consensus of two experienced radiologists. The MR imaging findings were analyzed by the size, shape and signal intensity of the mass, distension of the uterine cavity, the presence of cervical stenosis and the nature of the fluid collection. RESULTS: For the mass shape, all the ECRT lesions were polypoid masses. However, the SEC patients had 5 polypoid masses and 13 wall thickenings. The maximal diameter, signal intensity and enhancement pattern of the masses were not different between the ECRT and SEC patients. The width of the endometrial cavity varied between 3.9 cm in the ECRT patients and 0.4 cm in the SEC patients (p =0.002). All the ECRT patients had cervical stenosis. However, none of the SEC patients had cervical stenosis. CONCLUSION: MR imaging of ECRT patients demonstrated prominent distension of their uterine cavity and cervical stenosis, which may be the result of radiation fibrosis in the uterus.

The liver has a unique dual blood supply through the portal vein and the hepatic artery. There are several communications between these two vessels under various conditions such as in hepatic tumors, trauma and liver cirrhosis, vascular compromise, among others. When vascular compromise occurs, this dual blood supply system can cause changes in the volume of blood flow in individual vessels or even in the direction of blood flow. With rapid image acquisition and increased resolution available in multislice CT and MR imaging, hepatic perfusion disorders are now more frequently encountered than in the past. Familiarity with imaging findings of these perfusion disorders will be helpful in characterizing focal hepatic lesions and will also help to avoid false positive diagnoses.

Multidetector CT (MDCT) gastrography has been regarded as a promising technique for the preoperative imaging of gastric cancer. It has the ability to produce various three-dimensional (3D) images. Because 3D reconstruction images are more effective and intuitive for recognizing abnormal changes in the gastric folds and subtle mucosal nodularity than two-dimensional images, 3D MDCT gastrography can enhance the detection rate of early gastric cancer, which, in turn, contributes to the improvement of the accuracy of preoperative tumor (T) staging. In addition, shaded surface display and tissue transition projection images provide a global view of the stomach, with the exact location of gastric cancer, which may replace the need for barium studies. In this article, we discuss technical factors in producing high-quality MDCT gastrographic images and present cases demonstrating the usefulness of MDCT gastrography for the detection and T staging of gastric cancer while emphasizing the significance of preoperative localization of gastric cancer in terms of surgical margin.

OBJECTIVE: To examine whether the presence of high risk-human papilloma virus (HR-HPV) after conization of the cervix was a risk factor for persistence or recurrence of cervical intraepithelial neoplasia (CIN) and whether HR-HPV test could be a guideline for post-therapy surveillance. METHODS: The study retrospectively analyzed data from 243 patients who underwent LLETZ or CKC of the cervix due to CIN. RESULTS: A positive HR-HPV test result which was performed between 3 and 6 months after procedure was a risk factor for persistent or recurrent cytological (p<0.001, odds ratio [OR]=22.51, 95% confidence interval [CI]=9.74-52.02) and pathological (p<0.001, OR=18.28, 95% CI=5.55-60.20) abnormalities. CONCLUSION: HR-HPV positive patients between 3 and 6 months after procedure should undergo frequent and meticulous post-therapy surveillance, while HR-HPV negative patients do not require such high-level surveillance and could undergo routine surveillance.

PURPOSE: To assess the performance of contrast-enhanced three-dimensional(3-D) magnetic resonance venography (MRV) of the pelvis and lower extremities in patients with varicose veins. MATERIALS AND METHODS: Ascending and MR venography were performed in seven legs of seven patients, and duplex Doppler sonography and MR venography in 15 legs of 12 patients, all referred for evaluation of varicose veins. For analysis, the venous system as revealed by ascending and MR venographic images was divided into 13 segments. For detection of reflux to the great saphenous vein, duplex Doppler sonography and MRV were performed. RESULTS: In ascending venography and MRV, 91 venous segments were potentially visible; both modalities depicted 78 of these, but failed to detect four. Ascending venography and MRV detected 17 and 19 varices, respectively. When two tourniquets were placed around the ankle and knee using the Valsalva maneuver, MRV and duplex Doppler sonography detected reflux in 8 of 11 and 13 of 15 legs, respectively. CONCLUSION: Contrast-enhanced 3-D MRV comprehensively displays the venous system of the lower extremities and permits assessment of varicose veins. MRV using the Valsalva maneuver allows assessment of reflux to the great saphenous vein.

PURPOSE: An appendiceal mucocele refers to an abnormal dilatation of the appendiceal lumen by mucus. It is a rare clinical entity with a reported prevalence rate of 0.2~0.3% of all appendectomies. The purpose of our study was to identify the clinical characteristics of and the proper surgical management for appendiceal mucoceles. METHODS: The hospital records of 24 eligible patients were reviewed. We analyzed demographic data, and pathological and clinical data. RESULTS: There was a significant difference in size (P<0.009) between simple mucoceles (mean, 1.95 cm) and cystadenomas (mean, 3.6 cm). While ultrasonography was the most commonly used test to establish the diagnosis (14 patients), computed tomography and colonoscopy also provided fundamental information in 5 and 2 patients, respectively. An appendectomy was performed in most cases (20 cases, 83%). A cecectomy was performed in 3 cases, and an ileocecal resection was performed in only one case. Among the cases requiring a cecectomy, a laparoscopic cecectomy was performed in one case. A synchronous tumor was present in 5 cases. Three patients had gastric cancer, 1 patient had gallbladder cancer, the other one had endometriosis. CONCLUSIONS: Our study shows that appendiceal mucoceles most frequently present as acute appendicitis and that preoperative diagnosis is difficult to make. All mucoceles should probably be removed to eliminate the chance of progression to malignancy. Also of note was the elevated incidence of associated neoplasms, especially gastrointestinal carcinomas. Some recommend surveillance colonoscopy in patients with a diagnosis of an appendiceal mucocele. We had three cases accompanied by gastric malignancy. Therefore, we suggest that surveillance gastrofiberscopy may be indicated.
