The elbow joint is the most commonly dislocated-joint in the body except for the shoulder, and in children less then 10 years old, it is the most frequently dislocated articulation. The injury and the treatment are well described in most standard textbooks, but the characteristic findings and follow-up evaluations are not generally recognized. Authors have clinically analyzed 45 cases of traumatic fracture and dislocation of the elbow joint which are treated between January, 1975 and June, 1985 at the Department of Orthopedic Surgery, Wonju Medical College of Yonsei University. The results were as follows; 1. The age incidences were in even distribution except in the old ages where the incidence was low and the male to female ratio was 7: 3. 2. The major cause of the injury of the elbow was fall down (60%). 3. Posterior and posterolateral dislocations were about 60% of all cases. 4. Associated fractures were 35.6% of all the elbow dislocations, of which medial epicondyle fracture had the highest incidence. 5. Complications including ulnar nerve injury (3 cases), median nerve injury(1 case), radial nerve mjury(1 case), rupture of brachial artery(2 cases), recurrent dislocation(1 case) and calcification of ligament(2 cases) were observed. 6. Pure elbow dislocation occurred in 13 cases (28.9%). 7. The average immobilization period for patient with non-operative treatment (45%) and operative treatment(55%) were 7 days and 3 weeks, respectively, and much better results were seen in patients with non-operative treatment than in operative treatment and in shortened immobilization period.

Shortening and angular deformities in children are one of important orthopedic management problem. Conceptually, lengthening of the short side in treatment of limb length inequality is, in most instance, the most attractive approach to this problem. Throughout the evolution of lengthening procedures, the method that has remained most consistently acceptable is osteotomy followed by gradual distraction. However, the idea of increasing the length of or modifying the axis of s bone during growth by means of distraction of the grwoth plate is relatively new. Recently, Monticelli and Spinelli have had experience with a new and novel method of lower limb lengthening by physeal distraction. We have studied the results of effect of distraction epiphysiolysis and the use of nonsteroidal anti-inflammatory agents to impede bone bridge as well as premature epiphyseal closure. There are some reports in which indomethacin could prevent reformation of a bone bridge between the epiphysis and metaphysis without inhibiting normal growth and bone remodeling. For this study, a total of 30 rabbits with an initial weight of about 600 gram was used. At operation two K-wires(l.lmm in diameter) were drilled percutaneously on parallel trscks through the epipaysis and diaphysis of proximal tibia. Epiphyseal distraction of Turnbuckle type designed at our school was applied on each side of K-wire insertion at the tibia. The correct position of pin was confirmed by radiography and the rate of distraction is 0.5–1mm per day. Distrsction was continued for 3–6 weeks and radiographs was taken every 2 weeks. Some rabbits was sacrified sfter removal of distractor. Through these examination, following results were obtained. 1. Seperation of the epiphysis from the metaphysis occurred after average 3 days, and it always occurred in the zone of provisional calcification. 2. Short term results of growth plate distraction looked promising and longer limbs were seen, but long term results were unsstisfactory with premature epiphyseal closure and bone bridge formation occuring in many cases. 3. The role of indomethacine to impede bone bridge formation across the seperated growth plate could be observed, and was found that shortening could be possibly decreased. 4. Distraction epiphysiolysis would be one of valuable leg lengthening procedure at an age when the subjects bone growth is nearly complete, and also the administration of indomethacin with growth plate distraction might be effective to diminish the significant Change of shortening or angulation in high-risk juvenile fractures.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

We report herein a case of subcutaneous granuloma annulare occured in a 3-year-old girl who had 7 subcutaneous nodules on the scalp, lumbar area, buttock, right tibial area and both ankles. liistopathologically, multiple foci of complete and incomplete collagen degeneration surrounded by histiocytes in a palisading arrangement were seen in the subcutaneous layer. Some vessel walls were thickened and infiltrated with inflammatory cells and many eosinophils were scattered among the inflamrnatory cell infiltrate around the palisaiing granuloma. Five of the lesions disappeared spontaneously and other s decreased in size without specific treatment in 2 months.

Subungual exostosis are not uncommon, however, they are infrequently mentioned in the dermatologic literature. We report herein a rase of subungual exostosis in the great toe of 16-year-old female student which was confirmed by histopathologic and radiologic findings. Histopathologic examination showed that the mass was ooeered by a dense fibrous tissue which merged into a fibrocartilage cap and bone. Computed tomography showed a well defined, oval shaped, radiopacity of bony density capped by a radiolucency.

This study was performed to determine the effects of nitric oxide on human sperm cell function. Semen samples were obtained from normal healthy volunteers. Motile spermatozoas collected by swim-up method were incubated up to 24 hours in Ham's F-10 medium supplemented with a various concentration of sodium nitroprusside (nitric oxide releasing agent). Sperm motility, hyperactivation, acrosome reaction rate, and acrosin activity were determined. The results are as follows; 1. 1mM of SNP resulted in a significant decrease in sperm motility (44.8%+/- 8.9%:78.1%+/-6.3%, and hyperactivation (10.4%+/-6.4%:477%+/-9.5%) after incubation for 3 hours compared with the control group (Ham's F-10 alone), but had no effect on acrosome reaction. 2. At 100muM SNP, sperm motility was reduced after incubation for 6 hours (54.8%+/- 3.2%) compared with that of the control group (82.7% +/- 8.9%), but hyperactivation and acrosome reaction were not affected. 3. However, a lower concentration (less than 101M) of SNP had no effect on sperm motility and hyperactivation for 8 hours of incubation but significantly decreased them when incubation periods were increased up to 24 hours compared with the control group. On the other hand, 1muM and l0muM SNP significantly increased the acrosome reaction rate in both acrosomal status (17.3%+/-5.2%,23.5%+/-4.7%, respectively) and acrosin activity (34.3muIU+/- 10.5muIU, 45.6muIU+/-5.6muIU, respectively) as compared with the control group (7.0%+/-4.0%, 9.5muIU+/-3.4muIU). These results indicate that SNP, NO releasing agent, has a dose-dependent effects on the sperm cell function. Therefore it may positively affect the fertilization by promoting acrosomal reaction at a lower concentration (less than 101M).

7.Acute Nontraumatic Spinal Epidural Hematoma at Cervical Spine.
Journal of Korean Neurosurgical Society 2003;34(3):268-270
The authors report a case of acute nontraumatic spinal epidural hematoma which extending from C4 to C6. A 70-year-old woman was presented with neck pain and left hemiparesis. T1-weighted magnetic resonance image revealed a mass isointense to the spinal cord and the mass was slightly enhanced after administration of gadolinium. T2-weighted images revealed high signal in the left posterolateral part of the spinal canal at the level of C4-C6. Evacuation of an epidural hematoma was performed with laminectomy. The pathological examination did not reveal any malformation within this hematoma. The patient showed complete recovery of the deficits. Medical investigation yielded thrombocytopenia and splenomegaly derived from liver cirrhosis. Thrombocytopenia and mechanical factor may be considered as etiologic factors in this case.

PURPOSE: The aim of this study was to investigate treatment results, toxicity and efficacy of hyperfractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. MATERIALS AND METHODS: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hyperfractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 5 1 years. Initial FlGO stage was 1 stage IB1, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recur rent disease with superior margin at T 12, and inferior margin was between L5 and S 1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m to 30 mg/m (median, 25 mg/m'), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. RESULTS: Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75% and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30% and 3 7 months, respectively. At 1 month after treatment, 4 (40%) achieved a complete response and 6 (63%) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence in 2 patients after paraaortic node irradialion. There was 2 patients with grade 3 to 4 leukopenia and 8 patients with grade 1 to 2 nausea/ vom ting which was usually tolerable with antiemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. CONCLUSION: Hyperfractionated radiation therapy combined with paclitaxel as a radiosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer. Therefore, present results suggest that hyperfractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.

STUDY DESIGNS: A retrospective study. OBJECTIVES: To analyze the clinical and radiological outcomes of spontaneous reduction via minimally invasive transforaminal lumbar interbody fusion (Mini-TLIF) as the treatment for low-grade symptomatic spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Although minimally invasive transforaminal lumbar interbody fusion is technically demanding, this procedure is an effective method for spontaneous reduction of low grade spondylolisthesis. MATERIALS AND METHODS: We analyzed consecutive series of 41 patients with low grade spondylolisthesis who underwent minimally invasive transforaminal lumbar interbody fusion, between April 2008 and July 2009. The minimum follow-up period was 2 years. Clinical evaluation was performed by an analysis of Visual Analogue Scale and Oswestry Disability Index. For the radiological evaluation, disc space height, slip percentage, and slip angle were analyzed. At the final follow-up, the fusion rate was analyzed according to the Bridwell's anterior fusion grade. RESULTS: For the evaluation of clinical outcomes, the Visual Analogue Scale for back pain decreased from 6.8+/-1.2 to 2.0+/-1.1, and that for radiating pain decreased from 7.9+/-1.3 to 1.7+/-1.1. Oswetry Disability Index decreased from 38.5+/-8.4 to 13.4+/-6.1. For the radiological evaluation, disc space height increased from 8.4+/-2.14mm to 11.8+/-1.54mm(P<0.05), slip percentage was reduced from 18.4+/-5.1% to 13.3+/-3.1%(P<0.05) and slip angle decreased from 10.6+/-4.5degrees to 6.2+/-3.4degrees (P<0.05). At the final follow-up, radiological union was obtained in 38 cases (92.7%). CONCLUSIONS: We conclude that minimally invasive transforaminal lumbar interbody fusion appears to be an effective method for spontaneous reduction of low grade spondylolisthesis if the surgeon becomes familiar with this method.

We evaluated the renal function could be estimated by the visual analysis of the perfusion images of Tc-99m DTPA renal scan. Renal scan, creatinine clearance(CCr) and serum creatinine(s-Cr) were obtained in 105 patients. Intensity of renal activity(RA) at 6 sec perfusion image after the first visualization of abdominal aortic activity(A or A) was considered as the parameter for estimating renal function. Intensity of RA was scored from grade(Gr.) 1 to 3(Gr. 1: RAsplenic activity(SA), Gr. 2: RA
