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.

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.

8.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.

BACKGROUND: Photodynamic therapy(PDT) is a type of photochemotherapy that is designed to kill targeted tumor cells. OBJECTIVE: The Clinical effects of PDT were analysed for response rates, post-treatment healing and adverse effects on several cutaneous carcinoma in situ. METHOD: PDT with topical 5-aminolevulinic acid-based irradiation of corresponding 630+5nm light was performed in 6 carcinoma in situ patients who had actinic keratosis, Bowen' disease or cutaneous squamous cell carcinoma. RESULT: In all patients the clinical results were exellent with respect to initial complete responses and cosmetic outcome. CONCLUSION: PDT might be chosen as a first line treament for cutaneous carcimoma in situ.

Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.
