Between sept. 1982 and June 1985, the authors have performed arthroscopic debridement on 32 knees of 30 patients with primary osteoarthritis of the knee. Operative procedures including lavage, partial meniscectomy, excision of shelf, partial or total synovectomy of the anterior compartment, debridement of the articular cartilage, removal of loose bodies and multiple drilling of the articular cartilage were variously combined case by case. The follow-up period was between 18 and 52 months, with on average of 30.6 months. Clinical results were evaluated with the modified method of Sprague, III and were classified “Excellent”. “Good”, “Fair” and “Poor”. The data were analyzed by Fishers exact test to clarify the relationship between clinical results and various preoperative factors. The results were as follows: l. Of the total 32 knees, results were “excellent” in 17(53.1%), “good” in 9(28.1%), “fair” in 3 (9.4%) and “poor” in 3(9.4%) knees respectively. Satisfactory results, including “excellent” and good, were achieved in more than 3/4 cases(81.2%) . 2. Of the 3 “poor” cases, 2 cases seemed to be affected by major depression and the other one case had no specific cause to be considered. 3. The unsatisfactory cases, including “fair” and “poor” cases, commonly had degenerative changes of patellofemoral joint arthroscopically although the correlation between it and the results were not significantly proved statistically(P>0.05). 4. The correlation between amount of effusion, degree of degeneration of articular cartilage and amount of fibrinoid debris were not significantly proved statistically(P>0.05). 5. The correlation between clinical results and amout of effusion. degreq or site of degeneration of articular cartilage, degree of flexion contracture, meniscal tear, synovectomy, debridement of articular cartilage and number of operative procedures could not be significanly proved statistically. In conclusion, arthroscopic treatment of the primary osteoarthritis of the knee shows relatively satisfactory results in most cases with fewcomplications and a short rehabilitation period, and the procedure could be recommended as a process inbetween conservative treatment and definitive treatment such as total knee replacement. But any specific relationship between clinical results and various preoperative factors could not be proved statistically. The clinical results seemed to be attected by individual unknown factors and further precise analysis and long term follow-up will be necessary to clarify them.

Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

A total of 110 computed tomographic scans of the brain in pediatric population were reviewed. They wereretrospectively analyzed focusing on the ventricular dilatation, widening of subdural space in frontal region andprominence of cerebral sulci in hemisphere. The results were compared with clinical recored. In the measurementbicaudate ventricular index waas above 0.18, which ws considered ventricular dilatation. The subdural space in thefrontal region and teh prominent cerbral sulci in the hemisphere were visualized among the cases aged over twoyears with clinical evidence of cerbral problem is pediatric population. The diagnostic application of CT to thecases of cerebral disorder in pediatric population is highly recommended.

STATEMENT OF PROBLEM: Accurate impression is essential to success of implant prostheses. But there have been few studies about the accuracy of fixture-level impression techniques in internal connection implant systems. PURPOSE: The purpose of this study was to compare the accuracy of two fixture-level impression techniques in two conditions (parallel and divergent) and to assess the effect of tightening sequences and forces on stresses generated on superstructures in internal connection implant system (Astra Tech). MATERIAL AND METHODS: Two metal master frameworks made from two abutments (Cast-to Abutment ST) each and a corresponding, passively fitting, dental stone master cast with four fixture replicas (Fixture Replica ST) were fabricated. Ten dental stone casts for each impression techniques (direct unsplinted and splinted technique) were made with vinyl polysiloxane impressions from the master cast. Strain gauges for each framework were fixed midway between abutments to measure the degree of framework deformation on each stone cast. Pairs of strain gauges placed opposite each other constituted one channel (half Wheatstone bridge) to read deformation in four directions (superior, inferior, anterior, and posterior). Deformation data were analyzed using one-way ANOVA and the Tukey test at the .01 level of significance. And the effect of tightening sequences (right-to-left and left-to-right) and forces (10 Ncm and 20 Ncm) were assessed with ten stone casts made from parallel condition by the splinted technique. Deformation data were analyzed using paired t-test at the .01 level of significance. CONCLUSIONS: Within the limitations of this study, the following conclusions could be drawn. 1. Frameworks bent toward the inferior side on all casts made by both direct unsplinted and splinted impression techniques in both parallel and divergent conditions. 2. There was no statistically significant difference of accuracy between the direct unsplinted and splinted impression techniques in both parallel and divergent conditions (P>.01). 3. There was no statistically significant difference of stress according to screw tightening sequences in casts made by the splinted impression technique in parallel condition (P>.01). 4. Greater tightening force resulted in greater stress in casts made by the splinted impression technique in parallel condition (P<.01).
