The uterus with rudimentary horn occurs as a result of a lack of development during fetal life of the middle and lower parts of one of the Miillerian ducts, in which there is a failure of fusion of the two ducts, The incidence of this uterine anomaly is rare. Many cases of rudimentary uterine horn are not discovered since they do not become involved in a pregnancy, and thus remain symptomless and uncomplicated, and the diagnosis usually being made only with pregnancy with rupture. In this presentation, we describe a case of diagnosis and management of unruptured non-communicating rudimentary uterine horn pregnancy at the third trimester. The patient diagnosed by ultrasonography and MRI, was hospitalized for further evaluation and delivery under the impression of unruptured non-communicating rudimentary horn pregnancy. A living male infant weighing 1,930 gm was delivered by cesarean section at 33+l weeks due to impending preterm labor. Some articles concerned this subject were reviewed briefly to discuss relevant method of diagnosis, treatment, and clinical characteristics.

PURPOSE: Yearly many children attend hospital with burns. Most of them are injured to face and neck. In palliative ways, dressing with vaseline gauze, it is thick and tight to absorb the exdute and maintain, but patients are inconvinient in eating and speaking. Especially, in pediatric face and neck burn patients, cooperation is impossible, so there is increased risk of secondary infection by wound exposure and physician should make dressing more frequently. In case of using dressing material, it is not far different in palliative dressing, we should use a tape or elastic bandage to keep wound surface and dressing material in contact. Versiva(R) is combination dressing materials of hydrocolloid, hydrofiber, a polyurethane foam. Authors have used Versiva(R) in a treatment of pediatric face and neck burn, and we experienced that maintenance of dressing is convenient and nutrition supply is easy through oral feeding. METHODS: Between from 2006 January until 2008 December, we performed dressings with Versiva(R) in 20 pediatric second degree face and neck burn patients. Until postburn 2 nd or 3 rd day, we exchanged dressing daily, and after this, exchanged in 2~3 days according to amount of exudate. RESULTS: Versiva(R) had enough absorbing capacity and adhesive strength at the same time. With this slight and thin dressing material, there was considerable decrease in discomfort of patient, frequency of secondary infection and keeping dressing were convenient. Oral feeding was easy due to waterproof surface of the Versiva(R). In comparison with effort and time in palliative dressing, there was a significant reduction of labor force. CONCLUSION: In Treatment of pediatric second degree face and neck burn patient, Versiva(R) dressing was effective method because of decreased hospital day, convinience, labor reduction, decreased patient discomfort, easy to oral feeding.

Uterine rupture in the second trimester is rare, but it is a surgical emergency. Also it results rapid deterioration of patient and high mortality despite of prompt therapy and massive transfusion. Radiologic studies often do not allow definitive diagnosis of it, so clinical judgement is critical for optimizing patient care. We present a case of spontaneous uterine rupture with fetal death in 17 weeks of pregnancy due to placenta percreta with brief review of the literature.

Primary ovarian ectopic pregnancy has remained a rare event. It is difficult preoperatively to diagnose and differentiate ovarian pregnancy from hemorrhagic ovarian cyst and tubal ectopic pregnancy. However, improved diagnosis of acute hemoperitoneum of ovarian origin may reveal a higher incidence than reported earlier. The diagnostic criteria were described in 1878 by Spiegelberg, which comprise that the pregnancy is in the ovary and does not involve the tube. Ovarian pregnancy occurs within the ovary and on the corpus luteum, usually with rupture of the ovary and a massive hemoperitoneum. We report a relatively intact primary ovarian pregnancy with a brief review of the literatures.

This study was designed to clarify the cytotoxic effects of 6-hydroxydopamine (6-OHDA) on the dopaminergic neurons and astrocytes in the dorsal raphe nucleus (DRN), and to investigate neurodegenerative changes by immuno-histochemistry. Adult male rats (Sprague-Dawley strain) weighing from 250 to 350 g were used as experimental animals. 6-OHDA (100 micrometer dissolved in 0.1% ascorbic acid) was injected into the lateral ventricle of the rat brain with the Hamilton syringe. The control rats were treated with the similar volume of 0.1 % ascorbic acid. The rats were sacrificed at the 3rd, 5th, 10th and 20th day, respectively, after the injection of 6-OHDA. The cytotoxicity of 6-OHDA resulted in severe neurodegeneration of the dopaminergic neurons in the DRN. In the 3rd day, the dopaminergic fibers were dilated. In the 5th and 10th days, the dopaminergic fibers were depleted, and dopaminergic cell bodies were shrunken. In the 20th day, the dopaminergic cell bodies were almost completely disappeared. Astroglial reactions induced by 6-OHDA were also observed in the DRN. In the 5th day, astrocytes were significantly increased as compared with that of the control value. The value were reached at its maximum by the 20th day. Based on the present results, it suggests that 6-OHDA may act as a specific neurotoxin to dopaminergic neurons in the DRN, and induce severe neurodegenerative changes. Also, it suggests that the astroglial reaction in the DRN is gradually activated during the neurodegerative changes.

BACKGROUND: In Korea, the number of liver transplantation (LT) center is still changing. Many more centers are performing liver transplantations than that during the past decades. But several centers have stopped liver transplantation, while some centers have newly started performing liver transplantation. We present our initial experience in a newly built center as an example for any center that is considering performing LT. METHODS: A total of 33 consecutive adult LTs that were performed from June 2006 to October 2009 were analyzed by comparing the first 11 living donor liver transplants (LDLTs) performed with the help of an outside experienced team (group 2) with the second 11 LDLTs (group 3) and the 11 deceased donor liver transplantations (DDLTs) cases (group 1) that were independently performed in our center. RESULTS: There was no operative mortality for the donors and there were two operative mortalities for the recipients. During a mean follow-up of 27.1 months (range: 2 days~61 months), there were two cases of late mortality for the recipients. There were no re-operations and no major complications for the donors. The warm ischemic time was significantly longer in group 1 than that in groups 2 and 3. Otherwise, there was no significant difference in the operative outcomes among the three groups. CONCLUSIONS: Thorough preparation and the valuable assistance of an experienced liver transplantation team at the beginning can facilitate a more rapid learning curve and bring about good outcomes even in a small, newly established institution.

Exclusively dopamine producing retroperitoneal paragangliomas are extremely rare. We have experienced the first Korean case managed successfully based on the proper evaluation. A 26-year-old female patient came to our attention after the accidental detection of an adrenal mass. She had no symptoms and denied any family history. Laboratory evaluations were normal but serum dopamine (425 ng/L) and 24-hour urine dopamine levels (1,565.3 microg/day) were elevated. She underwent laparoscopic right adrenalectomy. Histopathological diagnosis was a paraganglioma. After operation, dopamine levels in serum and 24-hour urine dropped to 0.09 ng/L and 388.4 microg/day. Dopamine producing paraganglioma elicit no clinical symptoms. Only the dopamine level is elevated in serum and 24-hour urine samples. Surgical resection without using preoperative alpha blockage is the treatment of choice. The prognosis for patients with this tumor tends to be poor because the diagnosis is usually delayed due to lack of symptoms.

Earlier report showed that expression of a splice variant of CD99 transmembrane protein increases invasive ability of human breast cancer cells. Cell motility was also significantly enhanced by the CD99 splice variant expression. In an effort to identify the cellular components that mediate a signal transduction pathway triggered by the CD99 splice variant, known signal path inhibitors were examined for their effects on the motility of the CD99 splice variant-transfected MDA-MB-231 breast cancer cells. Phenylarsine oxide, an inhibitor of phosphatase specific for focal adhesion kinase, and PP1, an inhibitor of src kinase family, significantly suppressed motility of the cells. Among different types of src transfectant clones generated, kinase-negative mutant src transfectant cells were 80% less motile than the mock cells transfected with an empty-vector, while v-src and c-src transfectants exhibited cell motility levels at or slightly above the mock transfectant. These results suggest that src and focal adhesion kinase mediate the intracellular signaling pathway of a CD99 splice variant for the induction of motility of human breast cancer cells.

OBJECTIVE: To compare quantitative and qualitative image quality parameters in pediatric abdominopelvic dual-energy CT (DECT) using noise-optimized virtual monoenergetic image (VMI) and conventional VMI at different kiloelectron volt (keV) levels. MATERIALS AND METHODS: Thirty-six consecutive abdominopelvic DECT scans were retrospectively included. Noise-optimized VMI and conventional VMI were reconstructed at seven energy levels, from 40 keV to 100 keV at 10 keV intervals. The contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) of the liver, pancreas, and aorta were objectively measured and compared. Image quality was evaluated subjectively regarding image noise, image blurring of solid organ, bowel image quality and severity of beam-hardening artifacts. Optimal monoenergetic levels in keV for both algorithms were determined based on overall image quality score. RESULTS: The maximal CNR and SNR values for all investigated organs were observed at 40 keV in noise-optimized VMI (CNR and SNR of liver, pancreas, aorta in order [CNR; 20.93, 17.34, 46.75: SNR; 37.39, 33.80, 63.21]), at 60–70 keV and at 70 keV in conventional VMI (CNR; 8.12, 5.67, 15.97: SNR; 19.57, 16.66, 26.65). In qualitative image analysis, noise-optimized VMI and conventional VMI showed the best overall image quality scores at 60 keV and at 70 keV, respectively. Noise-optimized VMI at 60 keV showed superior CNRs, SNRs, and overall image quality scores compared to conventional VMI at 70 keV (p < 0.001). CONCLUSION: Optimal energy levels for noise-optimized VMI and conventional VMI were 60 keV and at 70 keV, respectively. Noise-optimized VMI shows superior CNRs, SNRs and subjective image quality over conventional VMI, at the optimal energy level.
