In 1988, a new fascioutaneous flap, the Lateral supramalleolar flap, was introduced by Masquelet and Roman. The flap is designed on the lower third of the aspect of leg, and supplied by a cutaneous branch from the perforating branch of the peroneal artery. This perforating branch continues distally deep to the fascia along the anterior ankle and into the foot. This can be use as either proximally based rotation flap or distally based reversed pedicle island flap giving the flap an arc of rotation that allows coverage of the dorsal, lateral and plantar aspects of the foot, the posterior heel and the lower medial portion of the leg. The authors have recently used this flap for 13 cases of foot and ankle soft tissue defect reconstruction and all the cases, except two partial marginal necrosis, good postoperative course. In our opinion, this flap is useful for reconstruction of foot and ankle soft tissue defect which does not need nerve innervation. The main advantages of the flap are as follows 1. It may be a rather large flap(15× 9cm2 ). 2. The pedicle is long(8cm) and easy to dissect. 3. The pivot of the pedicle is distal(sinus tarsi) and allows great local possibilities of coverage. 4. It does not require the sacrifice of a main artery.

OBJECTIVE: bjective: By identifying the unknown substance responsible for binding with nebulin SH3 domain within the sarcomeric Z-line, we tried to find out Z-line structure which plays an important role on muscle contraction and maintenance of muscle funtion. METHOD: First, the bait plasmid was made by binding the DNA binding domain of Gal4 protein of yeast and the SH3 domain. Second, library plasmid was made by binding activation domain and human skeletal cDNA library. Then, the base sequence of the clone, produced by combining the two proteins expressed by transgenically converted plasmid in yeast, was analyzed. RESULT: We screened out six true positive clones and analyzed the base sequence of the two of six clones. We identified them to be alpha-actinin2. CONCLUSION: We can theorize that Neublin SH3 domain and alpha-actinin2 plays a vital role for the integration of Z-line. Thus, this is an important data in further studying muscle functions, mechanisms, and muscular disease as well.

BACKGROUND: The glomerulonephritis appears in various clinical presentations. Renal biopsy is important diagnostic tool for treatment decision and prognosis prediction of glomerulonephritis. We tried to study on the clinical presentations of glomerulonephritis through histopathological findings and treatment responses in elderly patients. METHODS: We made an retrospective analysis in elderly patients aged over 60 years performed renal biopsy in our medical center from January 1991 to February 2005. RESULTS: Of all the 42 patients, the mean age of the patients was 64.6+/-3.5 years, 24 male and 18 female patients were included(1.3:1). Patients aged 60-64 years (n=26, 62%) were majority. On clinical indications of renal biopsies, 17 patients had nephrotic syndrome, 10 had asymptomatic urinary abnormality, 5 had gross hematuria, and 5 had acute azotemia. The results of renal biopsies presented that 30 patients (71%) had primary glomerulonephritis, 9 patients (22%) had secondary glomerulonephritis. Among primary glomerulonephritis, membranous nephropathy (n=10) was most common, followed by IgA nephropathy (n=7),focal segmental glomerulos-clerosis (n=3), membranoproliferative glomerulonephritis (n=2), and mesangioproliferative glomerulonephritis (n=2). In secondary glomer-ulonephritis, there were diabetic nephropathy (n=2), lupus nephritis (n=2), cancer-related nephritis (n=2), poststreptococcal glomer-ulonephritis (n=1), Henoch-Schonlein nephritis (n=1), amyloidosis (n=1). In the cases of nephrotic syndrome, primary nephrotic syndrome (n=12, 71%) is more prevalent than secondary nephrotic syndrome (n=3, 18%). The most common cause of primary nephrotic syndrome was membranous nephropathy (n=8). The causes of asymptomatic urinary abnormality were IgA nephropathy (n=4), lupus nephritis (n=2), membranous nephropathy (n=1), mesangioproliferative glomerulonephritis (n=1). By the complications of renal biopsy, only a few patients presented new-onset hematuria, hematoma, aggravation of hypertension, but, severe complication including an infection or a death was none. 8 of 12 patients with primary nephrotic syndrome were treated, 5 patients of those were shown complete response (n=3) or partial response (n=2). CONCLUSION: Various clinical presentations of glomerulonephritis were shown to elderly patients. Number of complications after renal biopsies were relatively small, and good responsiveness to treatment could be expected in the elderly patients. Therefore it is reasonable to perform a renal biopsy if indicated.

BACKGROUND: Multi-drug resistant (MDR) Acinetobacter baumannii has emerged as a significant infectious agent in hospitals worldwide. The purpose of this study was to determine the molecular characterization of MDR A. baumannii clinical isolates. METHODS: Two hundred eighty-five strains of non-duplicated A. baumannii collected from March to November 2011 from a university hospital laboratory located in the Wonju area of the Gangwon province of Korea were analyzed for MDR genes. RESULTS: All of the 285 imipenem-resistant A. baumannii isolates were encoded by a blaOXA-23-like gene, and all isolates with the blaOXA-23-like gene had the upstream element ISAba1. The 16S rRNA methylase gene armA was detected in 153 (50.2%) clinical isolates, but rmtA, rmtB, rmtC, rmtD and npmA were not detected in any isolates in the present study. The gene encoding aac(6')-Ib was the most prevalent aminoglycoside-modifying enzyme. The sequencing data for the quinolone resistance-determining region of gyrA and parC revealed the presence of Ser (TCA) 83 to Leu (TTA) and Ser (TCG) 80 to Leu (TTG) substitutions. All but one of the 285 A. baumannii isolates showed similar band patterns on repetitive extragenic palindromic-PCR profiles. CONCLUSION: The molecular characteristics of the resistance genes of MDR A. baumannii isolates obtained from the Wonju area of Gangwon province were similar to those of other areas in Korea.

BACKGROUND AND OBJECTIVES: Percutaneous occlusion of patent ductus arteriosus (PDA) has become increasingly attractive with the evolution of devices and techniques. We reviewed results for percutaneous occlusion of PDA using various devices in a single center. SUBJECTS AND METHODS: A retrospective review was done for 118 consecutive procedures performed in 111 patients with PDA between January 1996 and December 2007. RESULTS: The median age of the patients was 4.5 years (0.9 to 60.3 years); body weight was 16.9 kg (6.8 to 74.7 kg). The median PDA diameter at the pulmonic end was 3.8 mm (0.7 to 10 mm); mean pulmonary artery pressure was 21.0 mmHg (7 to 60 mmHg). Complete occlusion occurred in 76/111 (68.4%) immediately after implantation and in 100/111 (90.0%) at one year of follow-up. Second procedures for residual shunts were done in 7 patients. After the year 2001, the complete closure rate was 95.2% compared to 71.4% before 2001. Complications associated with the procedure were left pulmonary artery narrowing (all <20 mmHg) in 14, arrhythmia in 2, and death in 1. CONCLUSION: Evolution of devices, cumulative experience, and health insurance covering the cost of devices have contributed to good outcomes in our center for percutaneous occlusion of PDA. Our results have improved over the years, particularly with the use of the Amplatzer duct occluder.

BACKGROUND: All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. METHODS: Five hundred seventy-three fixtures on the maxilla posterior were included for this study from all the patients who underwent an installation of the dental implant fixture from January 2010 to December 2014 at the Department of Oral and Maxillofacial Surgery in Pusan National University Dental Hospital (Yangsan, Korea). The postoperative implant stability quotient (ISQ) value, fixture diameter and length, presence of either bone graft or sinus lift, and graft material were included in the reviewed factors. The width and height of the bone bed was assessed via preoperative cone beam CT image analysis. The postoperative ISQ value was taken just before loading by using the OsstellTM mentor® (Integration Diagnostics AB, Gothenburg, Sweden). The t test and ANOVA methods were used in the statistical analysis of the data. RESULTS: Mean ISQ of all the included data was 79.22. Higher initial bone height, larger fixture diameter, and longer fixture length were factors that influence the implant stability on the posterior edentulous maxilla. On the other hand, the initial bone width, bone graft and sinus elevation procedure, graft material, and approach method for sinus elevation showed no significant impact associated with the implant stability on the posterior edentulous maxilla. CONCLUSIONS: It is recommended to install the fixtures accurately in a larger diameter and longer length by performing bone graft and sinus elevation.

Individual identification procedure is one of the most improtant part in medicolegal fields. Recently, radiolegal investigation methods have been widely applicated to the medicolegal field for the purpose of individual identification. So authors attempted to determine sex and calculate stature by using roentgenographic findings of long bones of 248 subjects the living materials. In orthoscanographic study for long bones, we measured total length, midshaft width, epiphyseal width, cortical width, head diameter of each bones The total length, midshaft width, cortical width, condylar breath, horizontal & vertical head diameter of femur show statistically significant differentiation between two sexes, in tibia, total length, midshaft, cortical width, proximal and distal epiphyseal width show statistically significant. In fibula, Humerus, radius and ulna, total length is only statistically significant. And other wresults are statistically insignificant. Using femoral and fibial lengths (mm) with "Regression Analysis method" in SAS program, we derived the following fomulae. Height (cm)=95.62±0.148×Total length of Femur. (mm) Height(cm)=82.07±0.22×Total length of Tibia. (mm). In conclusion, radiologic measurement of long bone might be one of the useful methods in individual identification of unknown subject in Korea.
