MRI (magnetic resonance imaging ) had been the most up-to-dated modality in evaluating white matter disease in recent years, whereas US (ultrasonogram) has been used extensively in diagnosis of neonatal PVL(periventricular leukomalacia) conventionally. We evaluated the diagnostic value of MRI by reviewing the MR findings and correlation of MR and US of PVL in II preterm infants. Evaluation criteria were MR signal intensity and discrimination of PVL on each pulse sequences land comparision between MR and US findings performed simultaneously, on the extent of PVL, size of the largest cyst and detectability of hemorrhagic lesion. MR findings of 11 cases of PVL were of low signal patterns on T1WI (T1weighted image) in 7, low signal patterns of PDWI (proton density weighted image) in 9, iso signal patterns on T2WI(T2weighted image) in 8 and low signal patterns on STIR(short time inversion recovery) in 7 cases. The lesions of 11 PVL were well discriminated in all 11 cases of T1WI, 7 cases of STR, 5 case of PDWE and 2 cases of T2WI. The lateral ventricle was diffuse dilated (n=1) and focally dilated (n=3) in atrial area. In the comparative study, MR presented more extensive lesions in 7 cases, larger cysts in 6 cases out of 7 PVL and more definitive hemorrhage in 3 cases out of 4 cases than sonography. In conclusion MR was more valuable than sonography in evaluating the extent of lesions, size of the largest cystic lesion and detetion of hemorrhage. TIWI and STIR images were more useful in detection of PVL than T2WI and PDWI.

It is difficult to distinguish an islet tumor originating from heterotopic pancreas tissue from the other submucosal tumors. Although the malignant transformation of a heterotopic pancreas, including islet cell tumor, is extremely rare, it remains an important consideration in the differential diagnosis of duodenal submucosal masses. We have demonstrated the radiologic appearance and the clinical-pathologic findings of a highlighted, rare case of islet cell tumor arising from a heterotopic pancreas in the duodenal wall.

OBJECTIVE: The aim of the present study was to evaluate the impact of previous abdominal surgery on surgical outcomes of single-port access (SPA) total laparoscopic hysterectomy (TLH). METHODS: We reviewed the medical records of 111 women who underwent SPA-TLH at the Department of Obstetrics and Gynecology, CHA Gangnam Medical Center, CHA University between January 2010 and December 2010. Women were classified according to their history of previous abdominal surgery. RESULTS: Of 111 women undergoing SPA-TLH, 74 women (66.7%) without history of previous abdominal surgery and 37 women (33.3%) with history of previous abdominal surgery were classified. There was no significant difference in surgical outcomes including operative time, estimated blood loss, change in hemoglobin, uterine weight, perioperative complications, transfusion, and additional port insertion between two groups. CONCLUSION: In our experience, previous abdominal surgery has no significant impact on SPA-TLH.

OBJECTIVE: To examine the therapeutic outcomes of methotrexate (MTX) in the treatment of unruptured interstitial pregnancy. METHODS: We reviewed the medical records of patients who were diagnosed with interstitial pregnancy and received MTX as first-line treatment between January 2003 and July 2014 at CHA Gangnam Medical Center. The treatment success rates and subsequent pregnancy outcomes were examined. RESULTS: Ninety-seven patients were diagnosed with interstitial pregnancy between January 2003 and July 2014. Of them, 38 initially received MTX treatment. The diagnosis was made at a median of 6+3 weeks (5+0 to 11+3 weeks). Thirty patients received a systemic MTX injection, while the other 8 received a local MTX injection. Systemic treatment composed of an 8-day alternating MTX regimen, single-dose regimen, or high-dose regimen (100 mg/m2 + 200 mg/m2 intravenously over 12 hours). The local injection consisted of a direct MTX injection into the gestational sac with or without systemic MTX injection. Twenty-one patients (55.3%) were successfully treated with MTX. However, MTX therapy failed in 17 patients (44.7%), who required surgery. Mode of MTX treatment was the only predictive variable of MTX treatment success (P=0.039). Treatment success was seen in 7 of 8 patients (87.5%) in the local MTX group vs. 14 of 30 patients (46.7%) in the systemic MTX group. After treatment, 13 patients attempted a successive pregnancy; of them, 10 patients had a confirmed clinical pregnancy and healthy live birth. CONCLUSION: Combined MTX treatment including a local injection might be an initial approach to the treatment of interstitial pregnancy.

BACKGROUND/AIMS: Recent studies have suggested an important role of adipokines in the development of insulin resistance and diabetes mellitus. The clinical relevance of adipokines on long-term outcomes in patients with diabetes and chronic kidney disease is uncertain. The purpose of this study was to identify a predictable factor in patients with long-term diabetic complications. METHODS: A total of 161 diabetic individuals were followed-up from 2002 to 2013. Circulating plasma levels of adiponectin, glypican-4, irisin, visfatin, and visit-to-visit glucose variability were measured in diabetic patients. Associations among adipokines and variable metabolic parameters and microvascular, and macrovascular complications were evaluated. RESULTS: Plasma adiponectin and glypican-4 levels were significantly increased in patients with renal insufficiency. These adipokines were negatively associated with estimated glomerular filtration rate and positively associated with urinary albumin excretion. The relative risk of renal progression to dialysis increased independently with increasing level of adiponectin. Glypican-4 and visfatin were not predictive of any microvascular or macrovascular complications. Glucose variability increased the risk of diabetic nephropathy and cerebrovascular complications. CONCLUSIONS: Adiponectin and glypican-4 were associated with renal function and might be able to predict renal progression. Glucose variability was a predictable factor for diabetic nephropathy and cerebrovascular complications.

OBJECTIVE: To assess retrospectively the feasibility of intraoperative intraperitoneal (IP) chemotherapy with cisplatin in epithelial ovarian cancer. METHODS: IP chemotherapy during optimal staging surgery was performed in 10 patients who were diagnosed with primary epithelial ovarian cancers between April 2008 and February 2011. Cisplatin (70 mg/m2 in 1 L normal saline solution) was administered in the abdominal cavity for 24 hours postoperatively and then adjuvant chemotherapy was started 2-4 weeks after surgery. Perioperative toxicity of the combined treatment was evaluated until the initiation of postoperative adjuvant chemotherapy. RESULTS: A total of 23 adverse events were observed in 9 of 10 patients (grade 1, 7; grade 2, 13; grade 3, 3; grade 4, 0). In descending order of frequency, adverse events affected the gastrointestinal system (n=14), hematologic system (n=6), pulmonary system (n=2), and genito-urinary system (n=1). The adverse events did not affect adjuvant systemic chemotherapy schedules. One patient experienced disease recurrence in the liver 16 months after surgery. The remaining 9 patients have been well controlled by chemotherapy and/or observation during the follow-up period of 4 to 39 months after surgery. CONCLUSION: Intraoperative IP chemotherapy with cisplatin during surgical procedures is considered feasible for the treatment of primary epithelial ovarian cancer. Further studies, including long-term, prospective and comparative trials, are needed to validate the efficacy of this combined therapy.

Neurofibromatosis type I is an autosomal dominant disorder with varied manifestations in bone, soft tissue, the nervous system and skin. This is characterized by cafe-au-lait spots, neurofibromas, Lisch nodules, optic glioma, bony displasia, and intertriginous freckling. One of the more serious aspect of the disease relates to the arterial involvement. Vascular changes in neurofibromatosis may occur in any arterial tree from the proximal aorta to the small arteries but these changes are most common in the renal arteries, aorta, celiac arteries and mesenteric arteries. Of the many complications observed in neurofibromatosis type I, cerebrovascular lesions may be the least appreciated. About 40 cases of neurofibromatosis type I associated with occlusive cerebrovascular disorders have been reported in the literature, but MRI and angiographic findings typical of moyamoya disease are rarely described. We experienced a case of moyamoya disease associated with neurofibromatosis type I in a 3-year-old girl who of complained gait disturbance and paraparesis and showed findings typical of moyamoya disease on MRI and carotid angiogram.

OBJECTIVE: To evaluate the performance and reproducibility of a computer-aided detection (CAD) system in mediolateral oblique (MLO) digital mammograms taken serially, without release of breast compression. MATERIALS AND METHODS: A CAD system was applied preoperatively to the full-field digital mammograms of two MLO views taken without release of breast compression in 82 patients (age range: 33-83 years; mean age: 49 years) with previously diagnosed breast cancers. The total number of visible lesion components in 82 patients was 101: 66 masses and 35 microcalcifications. We analyzed the sensitivity and reproducibility of the CAD marks. RESULTS: he sensitivity of the CAD system for first MLO views was 71% (47/66) for masses and 80% (28/35) for microcalcifications. The sensitivity of the CAD system for second MLO views was 68% (45/66) for masses and 17% (6/35) for microcalcifications. In 84 ipsilateral serial MLO image sets (two patients had bilateral cancers), identical images, regardless of the existence of CAD marks, were obtained for 35% (29/84) and identical images with CAD marks were obtained for 29% (23/78). Identical images, regardless of the existence of CAD marks, for contralateral MLO images were 65% (52/80) and identical images with CAD marks were obtained for 28% (11/39). The reproducibility of CAD marks for the true positive masses in serial MLO views was 84% (42/50) and that for the true positive microcalcifications was 0% (0/34). CONCLUSION: The CAD system in digital mammograms showed a high sensitivity for detecting masses and microcalcifications. However, reproducibility of microcalcification marks was very low in MLO views taken serially without release of breast compression. Minute positional change and patient movement can alter the images and result in a significant effect on the algorithm utilized by the CAD for detecting microcalcifications.

BACKGROUND: To ensure safety of blood transfusion, accuracy in performance of blood grouping tests (BGT) is essential. External proficiency testing (PT) for BGT has not been conducted in Korea. The first PT for BGT in domestic blood centers was conducted in order to evaluate the domestic status of accuracy of BGT in blood centers and to aid in improving the quality of blood centers. METHODS: Whole blood survey specimens consisting of three panels for ABO grouping and two panels for Rh typing were sent to 81 blood centers. Evaluation criteria for BGT were as follows: 'Good' for answers with 100% referee consensus, 'Acceptable' for correct answers other than those of the referee, and 'Unacceptable' for answers other than those of 'Good+acceptable' as correct answers. RESULTS: Rates of correct answers on three panels for ABO grouping were all 100%; however, that of cell typing for the panel with BW was 61.7%, and 31 blood centers incorrectly reported normal 'B' type as an answer. The rate of correct answers for the Rh negative panel was 100%; however, that for the weak D panel was 84%, and 13 blood centers incorrectly reported Rh negative type as an answer. CONCLUSION: Findings from this study demonstrated that some hospital blood centers were not able to correctly detect blood groups with weak antigens. Therefore, to improve the quality of blood centers, intensive education for blood center staff and continued PT for BGT should be required.
