  • Picture Archiving and Communication System (PACS) has been planted as one of the key infrastructures with an overall improvement in standards of medical informationization and the stream of digital hospitalization in recent days. The kind and data of digital medical imagery are also increasing rapidly in volume. This trend emphasizes the medical image compression for storing large-scale medical image data. Digital Imaging and Communications in Medicine (DICOM), de facto standard in digital medical imagery, specifies Run Length Encode (RLE), which is the typical lossless data compressing technique, for the medical image compression. However, the RLE is not appropriate approach for medical image data with bilateral symmetry of the human organism. we suggest two preprocessing algorithms that detect interested area, the minimum bounding rectangle, in a medical image to enhance data compression efficiency and that re-code image pixel values to reduce data size according to the symmetry characteristics in the interested area, and also presents an improved image compression technique for brain CT imagery with high bilateral symmetry. As the result of experiment, the suggested approach shows higher data compression ratio than the RLE compression in the DICOM standard without detecting interested area in images.

  • Congenital bilateral idiopathic hyperplasia of the coronoid processes presents with limited mouth-opening without visible maxillofacial deformity or temporomandibular joint dysfunction / disorder. According to Blanchard et al and McLoughlin et al, it was lnitially described in 1853 by Langenbeck, and the first cases were reported by Holmes in 1956. Since then, there have been regular reports of a certain number of cases. In 1995, McLoughlin et al recorded 79 published cases of bilateral hyperplasia of the coronoid processes. Among them, Fabie et al have found only 3 published cases relating to children younger than 8 years, and have presented the first case of objectively diagnosed restricted mouth opening from birth by pediatricians. Authors have experienced 2 child patients with mouth opening limitation who was diagnosed congenital bilateral idiopathic hyperplasia of the coronoid processes without any other TNJ morphology in Dept of Oral and Maxillofacial surgery, Seoul National University Dental Hospital in 2004. Coronoidectomy was performed and postoperative active mouth opening exercise is indicated. Authors report 2 cases of congenital bilateial idiopathic hypeiplasia of the coronoid processes with literature liview.

  • Purpose: The anatomical anomaly of the rectus abdominis muscle and it's fascia is very rare. No case of the absence of the linea alba below the umbilicus has yet been reported. During breast reconstruction with pedicled TRAM flap, we experienced one case of absence of linea alba. Methods: The patient was a 38-years old female who underwent immediate breast reconstruction with pedicled TRAM flap after Right modified radical mastectomy in June 2010. While the TRAM flap was being elevated, bilateral twitching of the rectus abdominis muscle occurred when electrocautery was applied, and we found the absence of the linea alba below the umbilicus. Results: When the rectus abdominis muscle was exposed, the linea alba below the umbilicus was not observed, and the bilateral rectus abdominis muscle was indistinguishably fused in a gross observation. In addition, bilateral twitching of rectus abdominis muscle was simultaneously observed as one muscle unit when electrocautery was applied. As with both rectus abdominis muscles was bluntly dissected with scissors, the scanty fatty tissues were observed between the both rectus muscles, and the bilateral rectus abdominis muscle was easily separated. The flap was transposed into the corresponding defect to make breast mound. Midline fascia was fixed to the posterior rectus sheath to reconstruct smilar anatomic linea alba. Abdominal defect was reinforced by suturing between remaining anterior rectus sheath. Conclusion: As the unexpected anatomical anomaly may affect the operation outcome, surgeons should be careful when they unexpectedly encounter the anatomical anomaly during an operation. Here, we report a rare case of absence of the linea alba seen at the time of pedicled TRAM flap elevation for breast reconstruction.

  • A seven-year-old Yorkshire terrier 2.1 kg was admitted with a 2 months history of sever bilateral forelimb lameness and joint instability. Examination and radiographs revealed caudal luxation of bilateral antebrachiocarpal joint. Luxation of bilateral antebrachiocarpal (ABC) joint in a toy breed dog was treated with pancarpal arthrodesis. Modified external skeletal fixator (ESF) (type IIb) with polymethylmethacrylate (PMMA) was utilized in this case. Porcine cancellous bone graft (PCBG) was inserted to fill the joint space in carpus. The clinical and radiographic assessments of joint after the surgical procedure proved that PCBG can be used a promising alternative to Autogenous cancellous bone graft (ACBG).

  • An 11 year-old intact female Yorkshire Terrier weighing 3.5 kg was presented with the complain of having a perineal mass, fecal incontinence and tenesmus. Physical examination revealed reducible bilateral ventral perineal mass, enlarged mammary gland and vaginal discharge. Bilateral ventral perineal hernia (BVPH) and pyometra were diagnosed based on the clinical and radiographic findings. Ovariohysterectomy was performed after general anaesthesia to treat pyometra. The BVPH was repaired by herniorrhaphy with semitendinosus muscle transposition along with colopexy and cystopexy. The postoperative radiographs and CT revealed a good correction of the BVPH. The patient showed good activity after 10 days and no complications were observed during a one year follow up period. BVPH can be successfully surgically managed by herniorrhaphy with semitendinosus muscle transposition along with cystopexy and colopexy in the dog.

  • The world trading system has been under many changes in recent years. One notably important development is that much attention away from the multilateralism-oriented World Trade Organization towards FTA(Free Trade Agreement). The Free Trade Agreement signed between korea and chile formally have been come effective for free trade in goods and services as from April 1, 2004. During Free Trade Agreement negotiations between both countries. This study aims at presenting the suggestion for the Korea to make the WTO rules and FTA by analyzing The interpretation of FTA under WTO System. It was founded by the investigation of WTO rules, most of the provisions are similar with other FTA, but a little provisions different from other FTA's. It is an appearance from the contracting party's peculiar circumstances such as state of industrial development or future prospect, conditions around international trade. The whole world has entered the new stage of bilateral and multilateral FTA. The essential or new generation or bilateral and multilateral FTA is creating more trade opportunities, promoting all factors, commodity, service, capital, technology and talent freely flow through canceling the trade barriers between FTA, in order to develop together within the regions. It shows that the cooperations transfer form the whole region into FTA. FTA makes not only the free trade smooth ,but also takes place the trade distortion effect. especially as the agriculture has a speciality each country, should it is ignored in negotiation, many reactions will be occurred in the process of fta Therefore Korea needs to deliver the message that Korea's hub is an essential ingredient for an efficient FTA and WTO system in a bilateral and multilateral win-win framework. Consequently Korea should have criterions about the rules of FTA and WTO system for peculiar circumstances of Korean economy and international trade.

  • Background: Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. Materials and Methods: The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. Results: The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (p<0.05). There was no significant survival difference between patients with unilateral and bilateral hydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (p<0.05). Conclusions: Hydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

  • Background: The clinical significance of bilateral breast cancer is unclear and its influence on prognosis is controversial. Materials and Methods: Between 2005 and 2009 we identified 110 cases of bilateral breast cancer (BBC) ; 49 patients had synchronous (duration between the occurrence of carcinoma in both breasts was less than 12 months) and 61 had metachronous (duration was more than one year with no ipsilateral local recurrence). We compared the patient characteristics including age, menopausal status, clinical stage, tumor size, histological classification, lymph node status, and hormone receptor and Her-2 status. We also compared the treatment given and overall and disease free survival (DFS) of both groups. Results: Synchronous cases tend to present more aggressively than metachronous cases and age at first presentation adversely affects survival. The 5 year overall survival was 78.7% for metachronous and 60% for synchronous. Patients with positive hormonal status had better five year disease free survival in metachronous compared to synchronous cases, at 76% and 63%, respectively. Age at first presentation >45years had better DFS (65%) compared to those with age ${\leq}45$ years (52%) at 5 years follow up. Conclusions: Patients with synchronous breast cancer may have worse prognosis. Young age and hormone receptor negative were risk factors in our study. Close follow up and early detection of contralateral breast cancer is mandatory.

  • Granulocytic sarcoma is a manifestation of myelogenous leukemia, which means a solid mass consisting of primitive precursors of the granulocytic series of white blood cells. We present CT and MR imaging findings of bilateral sino-orbital granulocytic sarcoma in a 22-month-old boy. The mass involved bilateral orbital fossa which resulted in bilateral proptosis. Moreover, the mass extended to the almost skull base including paranasal sinuses, maxilla, temporal bone, zygomatic bone, sphenoid bone, ethmoid, and palatine bone. The adjacent dura was continuously thickened and the lower half of cavernous sinus was also involved. The patient was diagnosed as AML (M5) with t(8,21) translocation through a chromosome study from the bone marrow.
