PURPOSE: The purpose of this study was to analyze the results of treatment and prognosis of Marjolin's ulcer compared with primary squamous cell carcinoma. MATERIALS AND METHODS: Fourteen patients treated for Marjolin's ulcer were analyzed. Twenty patients with primary squamous cell carcinoma treated during the same time period was the control group. Mean age was 61.2 years. There were 24 males and 10 females. The locations, TNM stages, histological grades, recurrence, metastasis, and survival rate were analyzed and compared between two groups. RESULTS: The mean follow-up period was 54.8 months (range, 12-168 months). Local recurrences were found in 6 cases, 5 ones in Marjolin's ulcer patients, and one case in primary squamous cell carcinoma patients. The mean time interval between the initial presentation and occurrence of local recurrences was 9 months (range, 2-20 months). There were 6 metastases. 2 (14.3%) metastases were found in Marjolin's ulcer patients, and 4 (20.0%) metastases in primary squamous cell carcinoma patients. Total events (metastasis or local recurrence) were found in 10 pateients, 6 of them in Marjolin's ulcer group, and the remaining four in primary group. 5-year disease-free survival rate was 64.3% in Marjolin's ulcer group and 95.0% in primary squamous cell carcinoma group. CONCLUSION: Squamous cell carcinomas originating as Marjolin's ulcers revealed higher recurrence rate and lower survival rate despite of aggressive treatment. Therefore, new treatment modalities should be developed for improving outcomes.

This study was performed to evaluate the utilization and outcomes of palivizumab in high risk children born prematurely with chronic lung disease (CLD). A retrospective review of 128 patients was conducted from September 2004 to March 2009 at the Ajou University Hospital. All patients were diagnosed with CLD, were born at < or =35 weeks of gestation, were <2 yr old at the onset of respiratory syncytial virus (RSV) season, and had received medical therapy within six months prior to the RSV season. Fifty-three patients did not receive palivizumab prophylaxis and 75 patients received at least one dose of palivizumab. There were no statistically significant differences between the patients with and without palivizumab prophylaxis with regard to demographic characteristics and risk factors for RSV infection. There were no systemic adverse responses. Compliance with the course of prophylaxis was 92.2%. Hospitalization associated with RSV occurred in 12 cases (22.6%) in the group without prophylaxis and in three cases (4.0%) with prophylaxis. Palivizumab prophylaxis significantly reduced the frequency of RSV-related hospitalization in preterm children with CLD. This is the first retrospective review of palivizumab prophylaxis in Korea. Palivizumab is effective and well tolerated in high risk prematurely born children.

Twenty-nail dystrophy is a distinctive pattern of nail changes, in which all 20 nails are uniformly affected with excessive longitudinal ridging and loss of luster. It occurs at any age ranging from children to adulthood, however, it is most commonly diagnosed in children. It can be idiopathic or caused by other inflammatory dermatoses, but the exact cause and pathogenesis of these changes are so far unknown. Several treatment modalities have been employed for treatment of twenty-nail dystrophy, such as topical steroid, intralesional steroids injection, and topical PUVA, however, without much success. We herein report a case of an adults, patient with twenty-nail dystrophy which was successfully treated with topical 0.025% Tretinoin cream.

We studied the ultrastructural alteration of glomerular anionic sites in 6 patients with minimal change nephrotic syndrome, 5 patients with membranous glomerulonephritis, 4 patients with focal segmental glomerulosclerosis, and 4 patients with IgA nephropathy by staining with polyethyleneimine (PEI) as a cationic probe. The control study was examined by using a nephrectomy specimen of non-glomerular disease which had no proteinuria. This method seems to selectively stain heparan sulphate in the basement membranes and has been widely used to evaluate changes in basement membrane charge in various human diseases as well as in experimental studies. The anionic sites in the lamina rara interna and lamina densa of normal glomerular basement membrane were always less numerous and less regularly distributed than those in the lamina rara externa. Characteristic common findings in these glomeruli showed a marked decrease of glomerular anionic sites in the regions with immune-complex deposits and normal distribution in the regions with focally those being absorbed and newly forming glomerular basement membrane. They were not detected in the gap of the basement membrane and on the area of the detached overlying epithelium using the PEI method. But the foot process fusion of epithelial cells seems not to influence the loss of anionic sites on the glomerular basement membrane.

Hemifacial spasm (HFS) is a clinical syndrome characterized by unilateral facial nerve dysfunction. The usual cause involves vascular compression of the seventh cranial nerve, but compression by an artery passing through the facial nerve is very unusual. A 20-year-old man presented with left facial spasm that had persisted for 4 years. Compression of the left facial nerve root exit zone by the anterior inferior cerebellar artery (AICA) was revealed on magnetic resonance angiography. During microvascular decompression surgery, penetration of the distal portion of the facial nerve root exit zone by the AICA was observed. At the penetrating site, the artery was found to have compressed the facial nerve and to be immobilized. The penetrated seventh cranial nerve was longitudinally split about 2 mm. The compressing artery was moved away from the penetrating site and the decompression was secured by inserting Teflon at the operative site. Although the facial spasm disappeared in the immediate postoperative period, the patient continued to show moderate facial weakness. At postoperative 12 months, the facial weakness had improved to a mild degree. Prior to performing microvascular decompression of HFS, surgeons should be aware of a possibility for rare complex anatomy, such as compression by an artery passing through the facial nerve, which cannot be observed by modern imaging techniques.

Two aged patients who had open tibial fractures with arterial injury caused by high energy accidents underwent emergency arterial reconstruction using a greater saphenous vein and soft tissue repair using free flaps. In the patients, soft tissue necrosis developed and tibias were exposed at postoperative third week. Follow-up angiography through the superficial femoral artery showed occlusion of the anterior tibial artery. The anterior tibial artery was reconstructed using the contralateral greater saphenous vein graft and the latissimus dorsi myocutaneous and rectus abdominis muscle free flaps were transplanted for repair of necrotic soft tissue. The reconstructed arteries showed good perfusion to the new free flaps until union of the tibias occurred. The patients were followed-up for 21 years and 17 years postoperatively, respectively. In management of open comminuted fracture of the tibia, injury of the arterial system must be ruled out by angiography in addition to evaluation of the degree of soft tissue injury.
