Malignant MCA(middle cerebral artery) infarction is one of the leading cause of fatal stroke. It is usually caused by occlusion of the ipsilateral MCA or ICA(internal carotid artery). We report a 62-year-old man with posterior circulation stroke(distal basilar artery occlusion) which was later developed in malignant MCA infarction. MRI(magnetic resonance imaging) revealed high signal intensities in more than 2/3 of the right hemispheres and also in the bilateral thalamus, occipital cortices extending to the midbrain, pons and right SCA(superior cerebellar artery) territory of the cerebellum. Ipsilateral ICA and MCA of the infarcted hemisphere were not visible but ipsilateral PCA(posterior cerebral artery) seemed to be relatively prominent compared with the contralateral side in MR Angiography. From the pont of view of the initial pathologic brainstem sign and MR findings, we suggest that embolic occlusion of the distal basilar artery might be responsible for malignant right MCA infarction in this patient, from which the right PCA had dominantly supplied the most of the ipsilateral hemisphere.

PURPOSE: The goal of this study was to estimate development of secondary sex characters and genitalia including testicular volume, penile length and girth, and prevalence of varicocele. In addition, we evalua ted the relationship between testicular volume and presence of varicocele. MATERIALS AND METHODS: A cross sectional study was conducted on 893 school boys between the ages of 14 to 15 years, 3rd grade middle school in Chonju city during the period september to October, 1999. The testicular volume was measured in the upright posture using Prader's orchidometer and penile length and girth were estimated with a ruler. Varicocele was evaluated by dubin's method. RESULTS: The testis volume (mean+/-SD) was 10.20+/-2.6ml on right and 9.93+/-2.6 on left and penile length (mean+/-SD) was 10.9+/-1.6cm and penile girth (mean+/-SD) was 8.0+/-0.8cm. The prevalence of varicocele was 38.2% (342/893) in left side, 16%(146/893) in right side. The difference in testicular volume between right and left testis was statistically significant in students with unilateral varicocele than the students without varicocele (0.78+/-1.06ml v/s, 0.54+/-1.01ml, p=0.004). CONCLUSIONS: In this study, we obtained mean testicular volume, penile length and girth and higher incidence rate of varicocele on adolescent school age group in Chonju area. The difference in testicular varicocele. The reduction of the testicular volume with varicocele correlated with the severity of grade of varicocele need following up to disclose the effect of the varicocele on the testicular growth and fertility potential.

The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

Clinical observation was performed on the 84 hips of 72 patients which were replaced by total hip, who were treated at Department of Orthopedic Surgery, College of Medicine, Busan National University, from March 1978 to March 1981. The follow-up period of each case varied from 1 to 4 years. The results obtained were as follows: 1. The peak age incidence ranged from 51 to 60 years, which comprised 37.1% (23 patients) of total cases. 2. The causes of the hip diseases were; 25 cases of post-traumatic avscular necrosis of the head, which comprised highest incidence, 19 osteoarthritis, 14 primary avscular necrosis of the head, 4 ankylosing spondylitis, and 3 rheumatoirl arthritis. 3. The most commonly used prosthesis was Muller type in 64 cases (88.9%); Trapezoidal-28 in 3 cases; Ceramic-metal type in 4 cases; and modified Muller type by Japanese in 1 case. 4. Anterolateral approach was used in all cases except for the 3 cases in whom anterior approach was made. In most cases, greater trochanter osteotomy was not performed except for the 9 cases in whom operative field were poorly exposed without osteotomy. 5. Several complications developed; perforation of femur shaft and acetabulum during the operation in 1 case each, Post-operative deep seated infection in 2 cases, thrombophlebitis in 1 case, wire breakage in 2 cases, stem failure in 1 case, and femoral shaft fracture in 1 case. 6. Postoperative functional evaluation by the Merle d'Aubigne and Postel method was done; pain relief in 92.4%, mobility recovery in 71.6% and functional inprovement in 70.1% belonged to grade 5 and 6. Relief of pain is the most prominent effect of the total hip rep1acement surgery in this series.
