Between Aug. 1982 and Aug. 1983, computed tomographies of 52 patients with low back pain or low back pain with sciatica were performed at the Department of Orthopaedic Surgery, Korea University Medical College Hospital. All scans for patients were done on the Siemens Somatom II in the supine position. The auther studied level of hemiated disc, the measurement of herniation of the nucleus pulposus and buldging of the annulus fibrous in the midsagittal line. The results obtained are as follows: 1. Of all 52 patients with low back pain, 34 patients(65.4%) are interpreted as revealing herniated nucleus pulposus or buldging of the annulus, and the others demonstrated the different abnormality of lumbar spine. 2. Among 34'patients with buldging or herniated nucleus pulposus, 16 cases are noted at L4-L5, 12 at L5-S1, 6 at L4-L5 and L5-S1, respectively. 3. Mean size of herniated nucleus pulposus or buldging annulus in patients diagnosed as HNP are 1.04±0. 600 mm at L3-L4, 2.83±1.345 mm at L4-L5, 2.32±1.207 mm at L5±S1 and in patients diagnosed as other different diseases are 0.98±0.668 mm at L4-L5 1 .04+ 0.689 mm at L4-L5,1.03±0.489 mm at L5-S1.

5.Usefulness of PTFE Graft in Above-Knee Femoropopliteal Artery Bypass.
Journal of the Korean Surgical Society 2009;77(6):410-416
PURPOSE: Which graft material is appropriate for the above-knee femoropopliteal (AK fem-pop) bypass has been a controversy. We were to evaluate the usefulness of PTFE graft in AK fem-pop bypass by comparing the results of autogenous vein graft in below-knee femoropopliteal bypass. METHODS: This was a retrospective study of data for Fem-Pop bypass from August 1999 to August 2008. The median follow-up was 59.9+/-27.3 months. The demographic data, patency rate, secondary procedures, and amputation rate were compared, and statistical comparison was performed by Kaplan-Meier method, Log-rank test, and Chi-square test. RESULTS: Seventy-three bypasses were performed in 63 patients: PTFE graft in 48 cases (Group A), autogenous vein in 25 cases (Group B). Sixty-one patients (96.81%) were men. The mean age was 67.3+/-8.0 years. The indication for surgery was intermittent claudication in 27 cases (37.0%), critical limb in 46 cases (63.0%). The 6-yr primary patency rates were 28.1%; 60.3%, the 6-yr secondary patency rates were 37.2+/-8.4%, 67.0+/-14.7% in Group A and Group B, respectively (P<0.05). The number of secondary procedures was 31 and 3, respectively (P<0.05). Major amputation at later periods was not needed in Group B, but there were 9 cases in group A (P<0.05). CONCLUSION: PTFE graft for above-knee femoropopliteal bypass shows poor long-term patency with a large number of secondary procedures and a higher amputation rate than vein graft in BK Fem-Pop bypass. PTFE graft should be limited to patients with high operative risk, or poor venous graft.

Neonatal lupus erytematosus is a distinct subset of lupus erythematosus. It is characterized by cutaneous findings exhibiting the morphology of subacute cutaneous lupus erythematosus, congenital heart block, and anti-Ro/SSA and/or anti-La/SSB autoantibodies which result from the transplacental passage of maternal autoantibodies. We report a case of a 12-week-old female infant who presented with characteristic clinical and histopathological features of cutaneous neonatal lupus erythematosus but without evidence of congenital heart block. Initial serological studies reveled the presence of anti-La/SSB anti-bodies and antinuclear antibodies. 5 months later, follow-up serology was negative in accordance with a clinical remission.

A 38-year-old man presented with a black pigmented patch overlying his upper lip, a part of the gingiva and the hard palate. An intradermal tumor mass was palpated at the central portion of the pigmented patch of the upper lip. Diphenylcyclopropenone (DPCP) is a potent contact sensitizer that could stimulate non-specific immunity. We report a case of desmoplastic malignant melanoma (DMM) in which an atypical lentiginous pigmentation disappeared with topical DPCP immunotherapy and the dermal tumor mass was removed by a surgical wedge-shaped excision. Though an atypical lentiginous pigmentation of DMM sometimes undergoes extensive spontaneous regression, in our case it could be attributed to the therapeutic effect of topical DPCP immunotherapy rather than a spontaneous regression.

9.A Stent Graft Placement in a Focally Progressed Dissection in the Superior Mesenteric Artery.
Journal of the Korean Surgical Society 2010;78(2):127-131
Focal aneurysmal change after spontaneous superior mesenteric artery (SMA) dissection has been reported rarely. A stent graft implantation can exclude false lumen and possibly make major abdominal operation avoidable. A 52-year-old male patient was admitted due to abdominal pain for 10 days. A CT scan showed severe narrowing of the true lumen of SMA, approximately a 7 cm segment from the origin, due to compression by the thrombosed false lumen. Five days after admission, abdominal pain aggravated progressively. The follow-up CT revealed focal aneurysmal dilatation of the dissected SMA segment. I report here an endovascular treatment with stent graft implantation for a focal aneurysmal change after SMA dissection.

Minimally invasive surgery has gained wide acceptance as a method of reducing postoperative pain and curtailing the convalescence period. We have devised a modified surgical technique of laparoscopy-assisted surgery through minilaparotomy. It is a hybridized form of conventional open and laparoscopic surgery and it combines the benefits of both techniques by reducing postoperative pain and scarring as in laparoscopy, but at the same time maintaining the safety of conventional open surgery. From January 1992 to September 1999, we performed laparoscopy-assisted surgery through minilaparotomy in 167 patients. The operative time for laparoscopy-assisted surgery through minilaparotomy ranged from 79 to 290 minutes (mean 125). There was no conversion to open surgery, no peri- or postoperative complications, and only 3 patients needed a blood transfusion at any stage. Pain was significant on the first day but resolved quickly. All patients resumed consistent oral intake on the second day. All patients commenced ambulation by the second postoperative day and were able to resume full ambulatory activity by the fourth postoperative day. The final would size did not exceed 10 cm in size and all patients expressed satisfaction with their wounds. In conclusion, we believe that laparoscopy-assisted minilaparotomy surgery is a truly minimally invasive technique maintaining the advantages of conventional surgery. Our method could become a first-line approach for simple nephrectomy, living donor nephrectomy and radical nephrectomy, as well as surgery for kidney and ureter stones.
