It has been reported that the number of optic nerve fibers decrease with age, and the C/D ratio increases as the optic disc size increases. Consequently, the normal values of the optic disc parameters measured by an optic disc analyser may change according to the optic disc size or age. We attempted to investigate the effect of individual variations in optic disc size or age on interpretation of optic disc parameters. Topographic disc parameters of 104 normal subjects aged 40 to 69 were measured using a confocal scanning laser ophthalmoscope (TopSSTM , Laser Diagnostic Technologies, Inc.). Fourteen parameters were evaluated according to the optic disc size or age. Statistical analysis was done by regression analysis. With an increase in optic disc size, the increase in cup shape, effective area, 1/2 depth area, C/D ratio, neuroretinal rim area, volume above, volume below, and 1/2 depth volume were statistically significant (p<0.05). However, contour variation, mean contour depth, average depth, maximum depth, average slope, and maximum slope were not affected (p>0.1). Age did not show any statistically significant influence on optic disc parameters (p>0.1). In conclusion, optic disc size, but not age, should be considered in the interpretation of optic disc parameters.

Although traumatic bowing of one or both bones of the forearm in children following acute trauma was reported by some authors, traumatic bowing of the ulna with dislocation of the radial head was described by only a few reports. We experienced one case of traumatic bowing of ulna associated with dislocation of the radial head and it was managed with open reduction of the dislocation of radial head and closed management of the bowing of the ulna. The result 1 year 10 months after treatment was very good, so we report this a case with related literatures.

Plaster of Paris is an effective ancillary treatment in the surgery of infected cavities in bone. It is well tolerated and spontaneously absorbed over the period of weeks to months, being replaced by bone of normal architecture. When the antibiotics incorporated into plaster of Paris, the antibiotics are capable of prolonged local release in bactericidal concentrations. Therefore it is proposed that antibiotics loaded plaster of Paris might be a simple adjuvant technique after good surgical debridement for the treatment of bone infection. The authors carried out an experiment to study the effect of plaster of Paris containing antibiotics for a prevention of experimental osteomyelitis, using 45 rats, which were divided into 3 groups. In the Group 1, a defect was made at the proximal metaphysis of the tibia, inoculated by Staphylococcus aureus sensitive to Cephradine and Tobramycin and then filled with plaster of Paris pellet. In the Group 2, a defect was filled with Cephradine loaded plaster of Paris pellet. In the Group 3, a defect was filled with Tobramycin loaded plaster of Paris pellet. Then we observed the healing process of the bone defect in the point of view of the gross findings, radiologic findings and histologic findings at 4th, 8th and 12th week after operation. The results of this study were as follows:l. In the control Group;all 30 cases were infected. 2. In the Group 2;only 4 of 30 cases were infected. 3. In the Group 3;all 30 cases were not infected. 4. The plaster of Paris filled into the defect was absorbed continuously and stimulated the new bone formation.

STUDY DESIGN: A retrospective analysis was performed on 40 patients who had had previous lux bar spine surgeries. OBJECTIVE: To determine what factors most influenced surgical outcome and to analyze results in a series of revision lumbar surgeries. SUMMARY OF BACKGROUND DATA: Satisfactory surgical outcome of the revision lumbar surgery range from 28% to 82% and are rarely comparable to primary surgery. Many factors predicting outcome from repeat lumbar surgery haute been listed. METHODS: Forty patients were analyzed who had had previous lumbar surgeries. The patients were classified into 5 groups according to diagnosis: 3 Infection,5 instability,8 nonunion, 14 HNP and 10 spinal stenosis. of 40 patients,33 patients(82.5%) underwent fusion with instrumentation for repeat surgery. Their clinical course was followed for a minimum of 1 year. The number of surgery on each mpatient was 1.3 times on an average. RESULTS: Overall, 80% of patients had a satisfactory result. Obviously extruded or sequestrated HNP in MRI findings, complete block of contrast with severe radiculopathy and/or myelopathy in spinal stenosis, complete decompression, neurolysi s and fusion with instrumentation, and longer than 6 month pain relief after precious surgery were correlated with satisfactory outcome. However, the number of precious operation, age, repair of pseudarthrosis , no abnormality at surgery and combined multiple degenerative joint disease were significantly correlated with poor surgical outcome. The most common complication during repeat surgery was dural tear in 5 cases(12.5%). CONCLUSIONS: Success rate of revision surgery was low as compared to primary operation. Therefore, erroneous diagnosis and faulty surgical technique understandably lead to failure, and precise attention to preoperative and intraoperative detail can minimize these sources of error.

Fetal hydrops is often serious and associated with a high perinatal motality rate. Cardiac causes of fetal hydrops include congenital heart diseases and rhythm disturbances. An irregular fetal heart rate may indicate atrial fibrillation and atrial flutter with variable AV conduction. Fetal atrial flutter is characterized by the pressence of flutter waves which are regular sawtooth undulations in the baseline that are larger than p waves. Authors experienced a case of fetal atrial flutter with hydrops fetalis at 30 week's gestation which was confirmed by fetal M-mode echocardiogram and electrocardiography. A new born infant had shown to have atrial flutter in utero and after delivery was successfully converted to normal sinus rhythm with digoxin and quinidene.

Various kinds of bone cements mixed with antibiotics have been widely used for treatment and prevention of infections, especially combined with bone defects. But bone cements have some disadvantages in that they are rather expensive and capable of incurring some complications such ss fibrosis of surrounding soft tissue or local erosion of bone, and furthermore, they must be removed after infection is controlled for bone graft to fill up the defects because they do not have properties of osteoconduction or osteoinduction. So we have come to the idea of using theoretically advantageous plaster of paris to take place of bone cements, and performed in-vitro experiment upon the effectiveness of plaster of paris pellets containing antibiotics, then obtained good results comparable to those from many experimental studies using bone cements. By this, we think that it would be possible in the future to treat and prevent infections supervening bone defects with plaster of paris mixed up with antibiotics. The results are as follows : 1. Sustained release of large amount of antibiotics from plaster of paris enough to exert inhibitory activity on abcterial growth, and there was a direct relationship between concentrations of eluted antibiotics and diameters of inhibitory zones. 2. Tobramycin was capable of inhibiting the growth of S. aureus, E. coli, and Ps. aeruginosa for 7 days at maximum. 3. Cephradine inhibited the growth of S. aureus and E. coli but did not affect that of Ps. aeruginosa. 4. The maximum antibacterial activity wss reached within first 24 hours from the start of elution of antibiotics from plaster of paris.

Although several histopathological changes have been developed in frozen shoulder, frozen shoulder is mostly accompanied by the changes of the rotator cuff which has the most important function in movement and has a role in stabilizing the shoulder joint. The changes of the rotator cuff in frozen shoulder have not been reported in Korea yet, but Simon reported that there was an attenuation of the rotator cuff in frozn shoulder. Accordingly, we observed the changes of the rotator cuff in frozen shoulder by ultrasonography, which has no rsdiation exposure and is non-invasive. The authors practiced the shoulder ultrasonography on 36 patients with a pain and limitation of motion in shoulder at the Dept. of Orthopedic Surgery, Hangang Sacred Heart Hospital, Hallym University, from March in 1988 to August in 1988. The results are as follows ;1) Ultrasonography is thought to contribute a great deal in detection of the changes of the rotator cuff, especially of the thickness of the rotstor cuff. 2) Among 36 patients, the thickness of the rotator cuff of 35 patients was 6.494+1.008 mm (M+SD) in the affected shoulder and 6.475+1.052 mm(M+SD) in the unaffected shoulder. In only one pstient, the thickness of the rotator cuff was 1.68+0.58 mm(M+SD) in the affected shoulder and 553+1.16mm(M+SD) in the unaffected shoulder. Theres no significant change in the thickness of the rotator cuff measured by ultrasonography in frozen shoulder. 3) Ultrasonography is an excellent diagnostic method in detecting the rupture of the rotator cuff in frozen shoulder.
