Cardiac arrest associated with hyperkalemia during red blood cell transfusion is a rare but fatal complication. Herein, we report a case of transfusion-associated cardiac arrest following the initiation of extracorporeal membrane oxygenation support in a 9-month old infant. Her serum potassium level was increased to 9.0 mEq/L, soon after the newly primed circuit with pre-stored red blood cell (RBC) was started and followed by sudden cardiac arrest. Eventually, circulation was restored and the potassium level decreased to 5.1 mEq/L after 5 min. Extracorporeal membrane oxygenation (ECMO) priming is a relatively massive transfusion into a pediatric patient. Thus, to prevent cardiac arrest during blood-primed ECMO in neonates and infants, freshly irradiated and washed RBCs should be used when priming the ECMO circuit, to minimize the potassium concentration. Also, physicians should be aware of all possible complications associated with transfusions during ECMO.

We analyzed the clinical manifestations and results of 29 patients with orbital bone fracture who were repaired with Supramid(R) plate. The time interval between the day of injury and the operation averaged 84 days. Only 7 patients(25%) were operated within two weeks after trauma. The site of fractures were the orbital floor in 11 patients, the medial wall in 7 patients, both the medial and inferior wall in 10 patients, and the three walls of the roof, the medial, and the infereior wall in one patIent. During the average follow-up period of 9.4 months, there were significant improvement of symptoms and signs in patients on whom operations were performed within two weeks. Twenty-five percent of patients who were operated more than 2 weeks after recelvmg trauma showed no improvement of diplopia and imbalance of extraocular muscles. One patient showed optic nerve damage as postoperative complication, which was improved to the preoperative visual acuity three months after operation. No other complications such as implant extrusion or infection developed.

This study was carried out to investigate pathogenesis of E. coli-induced cystitis by light and electron microscopy with immunocytochemistry. A group of ICR mice was intravesically given 0.3ml of E. coli DIE 174 lysate( 1000000000/ml). Another group was given E. coli lysate after acid solution(pH 4.5) washing for 30 minutes. The urinary bladders were observed at 2 hours and 24 hours after E.coli lysate irrigation. On light microscopy, submucosal edema, congestion, and perivascular neutrophilic infiltration occurred 2 hours after E. coli lysate irrigation. The congestion and acute inflammation were more pronounced 24 hours after. In cases of acid washing and E. coli lysate irrigation, mucosal acute inflammatory infiltration with edema and congestion was marked at early stage. Necrosis of transitional cells developed with time. On immunostain for E. coli, surface of transitional cells was stained 2 hours after E. coli lysate irrigation. At 24 hours after irrigation, intercellular spaces of transitional cells were stained. In cases of acid washing and E. coli lysate irrigation, entire mucosa was stained at early stage. Electron microscopically, transitional cells revealed increase of cytoplasmic processes, enlargement of cytoplasmic vesicles, and widening of intercellular spaces. There were large amounts of various shapes of lysosomes in neutrophils and monocytes infiltrated in the mucosa in acid washing groups. According to the above results, it is concluded that E. coli lysate may easily penetrate into the bladder mucosa and that the mucosal mucopolysaccharide plays as a barrier against bacterial invasion.

For the successful surgical treatment of genuine stress urinary uncontinence many procedures have been applied. We report on 36 cases of stress incontinence surgically treated by the tansvaginal procedure (19 cases) and retropubic procedure(17 cases) during the period from November, 1981 to October, 1991. The patient varied in age from 34 to 65 years in the transvaginal procedure and 26 to 68 years in the retropubic procedure(total mean age was 47.2 years). The surgical procedures were performed by Pereyra`s method 17 cases. Stamey`e method 2 cases. MMK's method 11 cases. Montague`s method 1 case. Burch`s method 5cases. Clinical symptom classification (grade I - Grade IV)of stress incontinence reported by Ball was used. There were symptom distribution of Grade I, 3 cases ; Grade II, 14 cases; Grade III, 2 cases in the transvaginal procedure. Grade I, 3 cases; Grade II, 11 cases : Grade III, 3 cases were done by the retropubic procedures. The success rate was 84% in the trensvaginal procedure and 89% in the retropubic procedure with minimum follow up of six months. Postoperative complications were urinary retention 8 cases, bladder perforation 1 case, vaginitis 1 case (total 59%) in the transvaginal procedures, while urinary retention10 cases. wound infection 1 case (total 70%) in the retropubic procedures. The values of post-operative days on catheter, operative time and postoperative hospitalization in the transvaginal procedures were 6.8+/-2.1 days. 91.6+/-23.2 minutes and 7.2+/-0.5 days, and in the retropubic procedures 6.9+/-3.2, 123.5+/-21.5 and 7.8+/-0.6 respectively (p<0.01). On the basis of the results we concluded that the transvaginal procedure had advantages including operative simplicity, extensive indication, rarer postoperative complication, compared with retropubic procedures.

Total knee arthroplasty is indicated for painful joints, with or without deformity, secondary to rheumatoid arthritis, osteoarthritis, traumatic arthritis, and certain other forms of nonseptic arthropathy. Many patients with arthritic knees have symetrical involvement and thus require a bilateral operation. Staged bilateral arthroplastis were performed with many drawbacks such as prolonged hospitalization, repeated anesthetic risks, and increased cost. Simultaneous bilateral arthroplasty under one anesthesia by two teams offers several advantages over staged procedure. We studied the results of 145 total knee arthroplasties, performed over a five-year period, to compare unilateral(group I;45 knees), staged bilateral(group II; 24 knees), and simultaneous bilateral arthroplasties(group III; 76 knees) by 2 team approach. Duration of mean follow-up was 1 year and 9 months. The results are as flollows; 1. The mean anesthetic times were 189 minutes, 312 minutes, and 218 minutes for the group I,II,III, respectively. 2. The mean blood loss was 1075ml for the group I, 1644ml for the group II, and 1902ml for the group III. 3. The hospitalization period was 74.1 days in two stage procedures, while it was 48.6 days in simultaneous bilateral procedures. 4. Knee scores by Knee Rating Scale of Hospital for Special Surgery were increased to 85.3 points, 80.7 points, and 85.4 points for group I,II,III, respectively. 5. There were no difference in complication among three groups. 6. Group III had advantages such as reduced anesthetic risk, reduced rehabilitation period, and decreased cost.
