Osteochondral fracture of the patella is very rare in comparison to the other types of the patellar fracture. The mechanism of the most patellar fracture is dashboard or indirect injury. By sudden violent quadriceps contraction. But that of the patellar oeteochondral fracture is quite different from the mechanism of other types of patellar fracture, in that this fracture is frequntly caused by patellar subluxation or dislocation. We experienced one case of patellar osteochondral fracture, which at first was diagnosed as tibial spine avulsion fracture.

Two hundred and eleven patients with lumbar disc herniation at 242 levels were divided into 5 groups by their appearances on magnetic resonance imaging(MRI), and the findings at operation were compared to assess the accuracy of the MRI classification. There were no negative disc explorations. There was 92% sensitivity, 91% specificity, 91% specificity and 92% accuracy for MRI in distinguishing protruded discs from other forms of lumbar disc herniation. For sequestrated discs there was a 92% sensitivity, 99% specificity and 97% accuracy. In the extruded subligamentous type there was 71% sensitivity, 82% specificity and 79% accuracy, and 52% sensitivity, 92% specificity and 81% accuracy in the extruded transligamentous type. The overall accuracy of MRI predicting the types of herniated lumbar intervertebral disc was 85%. High resolution MRI is sensitive in detecting disc disease and specific in characterizing various subgroups of disc herniation, especially those which are sequestrated.

본 논문은 복강경 자궁근종절제술을 받은 여성에서 정맥 내 아스코르브산 주입이 피로에 미치는 영향 알아보고자 하였다. 우리는 무작위 배정 양측맹검 위약대조 임상시험의 2차 평가변수의 결과를 분석하였다. 복강경 자궁근종절제술을 받은 환자 50명은 수술 중 아스코르브산 (2g)이나 위약을 수술 중 투여받았다. 환자 비율은 임의로 1:1 비로 하였다. 수술 후 2일차에는 간이 피로 평가지 (Brief Fatigue Inventory-Korean version, BFI-K)을 사용하여 피로수준을 평가하였다. 대상자가 동의를 철회하거나 수술을 취소한 경우 또는 평가변수가 측정되지 않은 5명은 제외되어 총 45명(시험군 23명, 대조군 22명)을 대상으로 분석하였다. 분석에 포함된 대상자의 임상적 특성은 실험군과 대조군간의 차이가 없었으며, 전체 피로도 점수도 실험군 (4.56 ± 2.63). 대조군 (5.21 ± 2.02 P = 0.351)으로 두 군간에 차이를 보이지 않았다. 그러나 대조군의 피로도 점수는 대부분의 영역에서 대조군의 피로도 점수보다 낮은 경향을 보였다. 결론적으로 복강경 자궁근종절제술을 시행받은 여성에서 정맥 내 아스코르브산 주입은 피로도를 크게 줄이지 못했으며, 추가적인 연구가 필요하다. We assessed the effects of intravenous (IV) ascorbic acid administration on fatigue in women undergoing laparoscopic myomectomy. We analyzed the secondary endpoint results of a randomized, double-blind, placebo-controlled trial . Fifty patients undergoing laparoscopic myomectomy received IV ascorbic acid (2g) or placebo (randomly 1:1 ratio) intravenously during surgery. On day 2 post-surgery, we measured the level of fatigue using the Brief Fatigue Inventory-Korean version. Forty-five women (experimental arm 23, control arm 22) were eligible for analysis after 5 women (experimental arm 2, control arm 3) were excluded due to withdrawal of consent, cancellation of surgery or non-measurement of the endpoints. The baseline and operative characteristics were similar between arms and the global fatigue score of the experimental arm (4.56 ± 2.63) was not significantly different from that of the control arm (5.21 ± 2.02, P = 0.351). However, the fatigue score of the experimental arm tended to be lower than that of the control arm in most domains. IV ascorbic acid administration did not significantly reduce the level of fatigue in women undergoing laparoscopic myomectomy as compared to placebo. More research is needed to better understand the effects of ascorbic acid on fatigue in surgical patients.

Pyogenic, nontuberculous, spondylitis is relatively rare but has a clinical importance due to delay in diagnosis, severe morbidity, long period for treatment, etc. The prupose of this study is to outline a pattern of clinical features, treatment and prognosis to make guidelines for treatment. A clinical analysis was performed on 14 adult patients who were confirmed bacteriologically and histologically as pyogenic spondylitis and were treated at Asan Medical Center from September 1991 to May 1994. The follow-up period was 14 months in minimum and 23.5 months on average. The results were as follows. 1. All but one patient were over 47 years in age(55.6 years on average). 2. The interval between onset of symptoms and diagnosis was 48.7 days on average. 3. The lumbar spine was invooved most frequently. The numbers of cases of vertebral levels involved were 3(21.4%) at cervical spine, 1(7.2%) at thoracic spine and 10(71.4%) at lumbar spine. 4. The associated diseases or infections were diabetes mellitus(2 cases), gall stone(1 case), urinary tract infection(1 case) and infective endocarditis(1 case). 5. The causative organisms were isolated in 10 cases (71.4%) : Staphylococcus aureus in five, Streptococcus viridans in two, Streptococcus viridans and Enterococcus in one, Escherichia coli in one and Salmonella typhi in one. 6. Spontaneous bony fusion occurred in 3 among 7 patients who were treated conservatively and surgical fusion occurred successfully in all of the 7 patients who were treated operatively. 7. According to the Frankel's scale, there were 1 patient with Grade C paralysis ; 6 with Grade D ; and 7 with Grade E before treatment. After conservative or operative treatment, nevrological symptoms improved to Grade E in all but one patient whose symptoms lasted in grade D. 8. In conclusion, to minimize possible complications and sequelae in pyogenic spondylitis, early definitive diagnosis including successful culture and appropriate treatment, as indicated, are required.
