There is increasing need for network connecting personal computers(PC) together. Thus Local Area Network(LAN) emerged, which was designed to allow multiple computers to access and share multiple files and programs and expensive peripheral devices and to communicate with each user. We built PC-LAN in our department that consisted of 1) hardware-9 sets of personal computers(IBM compatible 80386 DX, 1 set:80286 AT, 8sets) and cables and network interface cards (Ethernet compatible, 16bits) that connected PC and peripheral devices 2) software - network operating system and database management system. We managed this network for 6 months. The benefits of PC-LAN were 1) multiuser (share multiple files and programs, peripheral devices) 2) real time data processing 3) excellent expandibility and flexibility, compatibility, easy connectivity 4) single cable for networking ) rapid data transmission 6) simple and easy installation and management 7) using conventional PC's software running under DOS(Disk Operating System) without transformation 8) low networking cost. In conclusion, PC-LAN provides an easier and more effective way to manage multiuser database system needed at hospital departments instead of more expensive and complex network of minicomputer or mainframe.

Fusional amplitudes can be measured using various clinical techniques and targets. But the vergence ranges are different according to the used instruments and the environmental conditions. Currently, measurement with the prism is usually llsed but this method have wide vardabele ranges by the used targets and environmental settings. The authors measured the vertical and horizontal fusional amplitudes of 135 normal Korean men with rotary prism in a well-lit office and compared the group using dim light targer with the group using small letter target. In the group using dim light target, true far convergence value was 14.67 +/- 6.24 delta, true far divergence was 6.64 +/- 3.48 delta, true near convergence was 24.96 +/- 7. 33 delta, true near divergence was 11.05 +/- 5.13delta, far vertical vergence was 2.93 +/-0.95 delta, and near vertical vergence was 3.40 +/- 1.15 delta, There was no statistical differences among are groups(p>0.05), and between the groups using small letter target and dim light target in true near and far convergence amplitudes (p>0.05). This study shows that the method using dim light target is simple and valuable method in measuring the fusional vergences.

Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because freque from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change

Objective: The optimal treatment for inhomogeneous chronic subdural hematoma (CSH) remains unclear. This study thus aimed to compare single burr hole drainage with minicraniotomy in the treatment of inhomogeneous CSH, including complication and recurrence rates. Methods: The clinical and radiologic data of 240 patients with inhomogeneous CSH who underwent surgery between January 2005 and January 2021 were retrieved. A total of 111 patients were included in this study. Clinical and radiological outcomes were compared between the groups undergoing different surgery types. Results: A total of 102 (91.8%) patients showed clinical improvement after surgery; 81 (93.1%) and 21 (87.5%) patients showed improvements in clinical symptoms in the single burr hole and minicraniotomy groups, respectively. A total of 102 (91.9%) patients showed favorable radiological findings after the surgery, including inhomogeneous CSH disappearance in 64 (73.6%) burr hole and 13 (54.2%) minicraniotomy patients, and inhomogeneous CSH improvement in 17 (19.5%) burr hole and 8 (33.3%) minicraniotomy patients. There were no significant differences in the patient characteristics or surgical outcomes between the groups. Conclusion Single burr hole drainage showed a slightly better improvement in clinical and radiologic findings and lower recurrence and complication rates than minicraniotomy. There were no statistically significant differences between the two groups.

BACKGROUND: Catheter ablation using radiofrequency energy has been established as the most important mode of treatment in patients with accessory pathway. However the ablation of midseptal accessory pathways had been recognized as being more difficult to ablate than other located pathway because of the low incidence and the difficult localization of ablation site. This paper describes the electrophysiologic characteristics of successfully ablated midseptal accessory pathway using radiofrequency energy. METHOD: Routine electrophysiologic studies were performed in 13 patients with midseptal accessorypathway. Guided by the recording of VA interval, the ablation catheter was positioned in all patients in an area bounded anteriorly by the tip electrode of the His bundle catheter and posteriorly by the coronary sinus ostium. Local electrograms during orthodromic atrioventricular reentrant tachycardia or right ventricular apical pacing were compared for 13 patients with midseptal accessory pathway and consequent 13 patients with posteroseptal accessory pathway. RESULT: 13 patients with midseptal accessory pathway; eight with constant Wolff-Parfinson-White syndrome, one with intermittent Wolff-Parkinson-White syndrome and four with concealed bypass track underwent attempts at ablation of their pathway using radiofrequency energy. 11 accessory pathways were successfully ablated without complication during the firstsession. A second attempt at ablation was made in two patients with success(one; recurred case, the other one; failed case at the first session). In the surface 12-Lead ECG, all eight patientswith constant Wolff-Pakinsin-White syndrome had not shownen Qrs complex at lead 3. Two patient with midseptal accessory pathway had transient left bundle branch block during orthodromic tachycardia. The VA interval during left bundle branch block was not change compared to that during narrow complex tachycardia in both. In all patients with midseptal accessory pathway, the VA interval in his bundle electrogram were almost similar to that in the coronary sinus ostial electrogram, which was not observed in the patients with posteroseptal accessory pathway. CONCLUSION: We suggest that VA interval during orthodromic tachycardia and right ventricular apcial pacing is the most reliable market for identifying midseptal accessory pathway, especially distinguishing from posteroseptal accessory pathway.

Supernumerary tooth, named mesodens, occur between the maxillary central incisors are generally found in pairs, although it is sometimes found singly. An inverted mesiodens may move toward the nasal cavity and erupt in the floor of the nose. Approximately 90% of all supernumerary tooth usually appear in the area of the maxilla, where they disrupt the position and eruption of normal teeth. A supernumerary tooth may closely resemble the teeth of the group to which it belongs, i.e., molars, premolars or anterior teeth.

PURPOSE: In recent years, single-port laparoscopic appendectomy (SPLA) has been gaining in popularity and there have been many reports on the results of SPLA. The purpose of this study is to investigate feasibility, safety, and cosmetic satisfaction with SPLA in treatment of perforated appendicitis. METHODS: From September 2012 to March 2015, 227 patients underwent SPLA at Damsoyu hospital. The patients were divided into the simple and gangrenous appendicitis group (the S & G group) and the perforated appendicitis group (the P group). Operation time, hospital stay, drain insertion rate, surgical complication, and cosmetic satisfaction were evaluated. RESULTS: A total of 227 patients consisted of 32 patients in the P group and 195 patients in the S & G group. There were no significant differences in the demographic data of the patients. The operation time and hospital stay were significantly longer in the P group (p=0.002 and p<0.0001, respectively). The rate of drain insertion was also higher in the P group (p=0.0002). However, no differences in postoperative complications (p=0.281) and cosmetic satisfaction (p=0.090) were observed between the two groups. CONCLUSION: SPLA for perforated appendicitis is a feasible, safe, and cosmetically acceptable procedure. However, longer operation time and hospital stay and higher drain insertion rate should be considered for patients undergoing SPLA for perforated appendicitis.
