Between May 1982 and October 1983, arthroscopic meniscectomy had been performed in 54 knees between ages of 11 and 70 years. There were 32 male patients and 22 female patients in this series. The mean follow-up was 20 months, ranging from 15 months to 33 months. Postoperative complications developed were retropatellar tenderness and effusion. No infection, thrombophlebitis or instability occurred postoperatively. The aim of this study was to evaluate the effect of the various possible prognostic factors upon the developtnent of the above mentioned complications. The factors included were 1) shape of tear, 2) ligamentous injury, 3) degenerative arthritia, 4) discoid lateral meniscus, 5) quadriceps atrophy, 6) sites of meniscus(medial or lateral) & extent of excision, 7) preoperative retropatellar tenderness and 8) method of rehabilitation. The findings were statistically analyzed by the Chi-square test (df-1) & Fisher's direct probability method. The results obtained were as follows; 1. The rate of development of postoperative effusion was significantly high in cases of quadriceps atrophy (P<0.01) and preoperative retropatellar tenderness(P<0.01). 2. The rate of deveopment of postoperative retropatellar tenderness was significantly high in case of discoid lateral meniscus (P <0.01). 3. There was no significant correlation between complications and other factors including shape of tear, preoperative degerative arthritis, site of meniscus & extent of excision and methods of rehabilitation.

Hysterosalpingography and Hysteroscopy have been used for the detection of intraute-rine pathology such as polyps, submucous myomas, intrauterine adhesion and endometrial hyperplasia or cancer. Recently the ultrasound has also been utilized for the detection of uterine pathology. Therefore the purpose of this study was to evaluate the diagnostic efficacy of SonoHysterography in detection of intrauterine pathology compared with HSG and Hysteroscopy. 32 patients underwent Sono-Hysterography and Hysteroscopy for the evaluation of the uterine pathology from september 1995 to January 1996. Nine of 32 patients had infertility problem and HSG performed prior to Sono-Hysterography and Hysteroscopy. The results are as follows : 1. The patients' ages ranged from 20 to 50 years(median 37.9). 2. All 9 patients with infertility who had positive HSG findings in uterine cavity showed the intrauterine pathology in Sono-Hysterography as well as Hysteroscopy. The detail findings are as follows :septated uterus(n=2), intrauterine adhesion :IUA(n=3), endometrial polyp(n=3), and IUA combined endmetrial hyperplasia(n=1). 3. Twenty two of 23 patients with abnormal uterine bleeding showed the intrauterne pathology and one patient had negative finding in Sono-Hysterography. However, Hysteroscopy revealed positive intrauterine pathology in 22 patients who had abnormal uterine bleeding. One patients who had positive finding in Sono-Hysterograply showed negative by Hysterography. In contrast, one patient who had negative finding in Sono-Hysterography had positive uterine pathology with polyp in Hysteroscopy. The histologic pathology in all 23 patients reported endometrial polyp(n=12), placental polyp(n=2), submucous myoma(n=1), endometrial hyperplasia(n=5), endometrial cancer(n=1), normal endometrial finding(n=2). 4. Sono-Hysterography, therefore, has a sensitivity and positive predictive value of 96.6%, 93.5% respectively. Our study showed a positive Sono-Hysterography is very predictive of the intrauterine pathology. Sono-Hysterography is safe, quick and minimal invasive procedure. So it is an invaluable technique in the evaluation of uterine cavity.

Sixty schizophrenia patients who committed homicide and detained after January 1, 1993 were divided in two groups, depending on whether their victim was a family member or not. Below conclusions were deduced from the comparison of the two groups in terms including demographic characteristics, onset and duration of illness, IQ score, suicidal attempts, history of alcohol/drug abuse or past crime, neuropsychiatric ward admission history, living circumstance, conflict with the victim, and adolescent conducting behavior. 1. More in the family homiciding patients (FHP) group lived alone due their unmarried, divorced, or separated marital status than those in the non-family homiciding patients (NFHP) group. More in the FHP group were in married state than those in NFHP group. 2. More in the NFHP group stayed alone apart from their family, while more in the FHP group lived with their family. 3. Those in the NFHP group show more frequent suicidal attempts than those in the FHP group, implying they have difficulties in the control of their impulsive behaviors. 4. To prevent the crime, it is essential for the government to practice the systematic support and care of the schizophrenia patients who are living alone, especially those without relative.

PURPOSE: The purposes of this study were to analyze the MR findings of medulloblastoma, and to evaluate the subarachnoid dissemination and the significance of contrast enhanced MR of brain and spine for tumor.. MATERIALS AND METHODS: The preoperative brain MR studies of 18 patients (9 males, 9 females;mean age, 9.4 years) with surgically proved medulloblastomas were retrospectively reviewed to characterize these neoplasms with regard to their location, size, MR signal intensity, appearance after contrast enhancement, presence of cyst and necrosis, subarachnoid dissemination, and other associated findings. In 14 patients postoperative spine MR studies were evaluated for staging and therapeutic planning. RESULTS: The most frequent location of medulloblastoma was the inferior vermis and the mean tumor size was 4.1 x 3.6 x 3.9 cm. On Tl-weighted image, medulloblastomas generally had low to intermediate signal, predominantly hypointense relative to white matter. On T2-weighted image, medulloblastomas showed modetately high signal, hyperintense relative to white matter. Inhomogeneous contrast enhancement was demonstrated in 13 patients(72.2%) after injection of gadopentetate dimeglumine(Gadolinium). Cyst and necrosis within the tumor were visualized in 15 patients(83.3%). Subarachnoid disseminations of medulloblastomas were noted in 11 patients(61.1%), of which 6 demonstrated intracranial and 2 intraspinal dissemination. Three had both intracranial and intraspinal dissemination. In nine cases with intracranial lesions, there were intraparenchymal mass formation(7), subarachnoid nodules(5), infundibular lesions(2) and diffuse gyral enhancement(I). In five cases with intraspinal lesions, there were extramedullary intradural small nodules(3), central canal nodules(2), intradural masses(I)and fine nodular and sheet-like leptomeningeal enhancement(1). Other associated findings included intratumoral hemorrhage(11.1%), per/tumoral edema(44.4%), tonsillar herniation(44.4%), hydrocephalus(88.9%) and calcification(44.4%). CONCLUSION: Medulloblastomas revealed low to intermediate signal intensity on Tl-weighted image and intermediate to moderately high signal intensity on T2-weighted image, relative to cerebellar white matter. Medulloblastomas were solid tumors with cystic necrosis, which showed inhomogeneous enhancement and subarachnoid disseminations to the intracranial and intraspinal spaces after Gd-DTPA enhancement. Gd-enhanced MR of brain and spine was an useful diagnostic modality in preoperative diagnosis and in staging of postoperative cases of medulloblastomas, which was superior to postcontrast CT or precontrast MR.

PURPOSE: To examine the fate of muscle-derived stem cells (MDSC) after injection into different host conditions and provide an insight for their mechanism of action. MATERIALS AND METHODS: MDSCs differentiated in vitro towards the endothelial lineage and transfected with lentivirus tagged with green fluorescent protein (GFP) were injected into two animal models mimicking vascular diseases: hindlimb ischemia and carotid injury models. Injected cells were tracked at the site of injection and in remote organs by harvesting the respective tissues at different time intervals and performing immunofluorescent histological analyses. Stem cell survival was quantified at the site of injection for up to 4 weeks. RESULTS: MDSCs were successfully tagged with fluorescent material GFP and showed successful implantation into the respective injection sites. These cells showed a higher affinity to implant in blood vessel walls as shown by double fluorescent co-stain with CD31. Quantification of stem cell survival showed a time-dependent decrease from day 3 to 4 weeks (survival rate normalized against day 3 was 72.0% at 1 week, 26.8% at 2 weeks and 2.4% at 4 weeks). Stem cells were also fo und in distant organs, especially the kidneys and liver, which survived up to 4 weeks. CONCLUSION: MDSCs were successfully tracked in different vascular disease models, and their fate was assessed in terms of cell survival and distribution. Better understanding of the donor cell properties, including their interaction with the host conditions and their mechanism of action, are needed to enhance cell survival and achieve improved outcomes.

9.Body Composition Changes in Korean Children and Adolescents.
Journal of Korean Society of Pediatric Endocrinology 2010;15(1):7-13
The term body composition describes the percentages of fat, bone, and muscle in the human body; it reflects the nutritional or growth status in children and adolescents. Further, its evaluation is clinically important to assess the nutritional abnormalities, growth failure, progress of chronic diseases, or treatment measures for these conditions. Body composition parameters such as total body fat and fat distribution are risk factors for metabolic disease not only in adults but also in children and adolescents. Inadequate bone mineral acquisition and failure to achieve peak bone mass is a risk for subsequent osteoporosis. Therefore, measuring the body composition is important to ascertain the natural course of metabolic diseases and to develop strategies for their prevention because the body composition of children and adolescents is predictive of their body composition as adults. This article will review the basic concept and methods of measuring body composition. This review also deals with the evaluation of body composition in Korean children and adolescents. Because the body composition of individuals differs with age, body weight, puberty, sex, race, and ethnicity, it is important for pediatricians to know the characteristics of the body composition change in Korean children and adolescents.

Emphysematous cystitis is a rare condition characterized by gas collection in the wall and lumen of the bladder. We experienced three cases of emphysematous cystiris. All patients were female; one was associated with a long term history of diabetes mellitus and another with urinary indwelling catheter. All of the cases were easily diagnosed on plain radiograph and CT scan, and were successfully treated with antibiotic therapy. In one of the cases, however, associated abscess due to perivesical extension of inflammation was treated by combined external drainage.
