Sebaceous carcinoma is a particularly common malignant tumor of the eyelid. Therefore, this lesion is important to ophthalmologist. Recently, there appears to have been an increased incidence or recognition of sebaceous carcinomas of the eyelid, which had been previously believed to be very rare. Frequently mistaken for a recurrent chalazion, invasion by sebaceous carcinoma is frequently enhanced by repeat curettage and forms of therapy that obscure the true diagnosis. This tumor is difficult to completely resect due to intraepithelial widespread, so its prognosis is poor. The authors experienced two cases of sebaceous carcinoma of the eyelid. One was a 57 year old female patient who was treated with surgical resection and the other was a 71 year old male with cervical lymph node metastasis. He was treated with surgical resection, but he rejected radiotherapy.

BACKGROUND: Although a magnetic resonance imaging (MRI) is highly sensitive for changes associated with ischemic stroke, the detection of an acute ischemic lesion is usually impossible within 6 hours of the stroke onset on a conventional MRI. The perfusion MRI is a new imaging technique for diagnosing acute ischemic stroke. We evaluate the clinical usefulness of the perfusion MRI in predicting the final infarct extent in 18 patients with acute middle cerebral artery (MCA) territory ischemic stroke. METHOD: The perfusion MRI was performed within 6 hours after the stroke onset in all patients with a single-section dynamic contrast-enhanced T2*-weighted imaging in conjunction with a conventional routine MRI and MR angiography. Time-concentration curves and cerebral blood volume (CBV) maps were calculated from the dynamic MR imaging data by using numerical integration techniques. We compared findings of CBV maps with infarction on a follow-up CT or MRI. RESULTS: In 14 of 18 patients, the CBV in the occluded MCA territory were decreased. In the remaining 4 patients with a reversible ischemic neurologic deficit (RIND) or transient ischemic attack (TIA), the CBV were increased in 3 and normal in 1. Out of 14 patients with a decreased CBV, two had focal regions of increased CBV within the affected territory, indicating reperfusion hyperemia. The regions of increased or decreased CBV were eventually converted to infarction on follow-up images in all 14 patients. Out of 4 patients with RIND or TIA, one showed focal infarction in centrum semiovale on a follow-up image. CONCLUSIONS: The perfusion MRI was useful for the assessment of hemodynamic change about cerebral perfusion and may predict the extent of final infarction in acute MCA territory ischemic stroke. These results suggest that the perfusion MRI may play an important role in the diagnosis and management of acute ischemic stroke.

Two patients were presented with painful unilateral oculomotor nerve palsy and one of them was combined with trochlear nerve palsy. First case was initially thought to have diabetic opthalmoplegia, and second case was thought to have posterior communicating or distal internal carotid aneurysms. But both had, in fact dural carotid cavernous fistula, draining posteriorly into inferior petrosal sinus. Embolization was done in these two cases, which was followed by clinical improvement in one case.

PURPOSE: To assess the usefulness of 0.5 %-methylcellulose as oral contrast agent in spiral CT examinationsfor the evaluation of anastomotic site and remnant stomach in patients who have undergone subtotal gastrectomy dueto stomach cancer. MATERIALS AND METHODS: Twenty-seven patients who underwent subtotal gastrectomy for stomachcancer and were referred for the evaluation of anastomosis recurrence and lymph node metastasis wereprosepectively analyzed by spiral CT. They were divided into two groups: before scanning, group A patients drank0.5 %-methylcellulous 500ml as oral contrast agent, while those in group B drank diluted gastrografin 500ml. Threepatients were examined twice. Anatomic delineation of the anastomosis site was graded by two radiologists asexcellent (3), good (2), fair (1), or poor (0). To evaluate the degree of distension, maximal transverse andanterior-posterior diameter of remnant stomach and anastomotic sites were measured. RESULTS: In Group A, anatomicdelineation of the anastomotic site was very much better than in group B (mean score: 2.93 vs 1.80, p<0.05). Inaddition, the maximum diameters of remnant stomach and anastomotic site were significantly larger in group A thanin group B (transverse A-P remnant stomach and anastomosis site: 87.5 +/-14.7mm, 103.3 +/-20.1mm, 17.6 +/-2.9mm vs57.6 +/-20.1mm, 69.9 +/-3 5 . 0 m m , 10.7 +/-7 . 2 m m ) CONCLUSION: In patients who had undergone subtotalgastrectomy, the use of 0.5 %-methylcellulose as oral contrast agent for spiral CT showed excellent anatomicdelineation of the anastomotic site and distension of remnant stomach.

PURPOSE: We sought to evaluate the clinical usefulness of decision making by a multidisciplinary heart team for identifying potential candidates for transcatheter aortic valve implantation (TAVI) in patients with symptomatic severe aortic stenosis. MATERIALS AND METHODS: The multidisciplinary team consisted of two interventional cardiologists, two cardiovascular surgeons, one cardiac imaging specialist, and two cardiac anesthesiologists. RESULTS: Out of 60 patients who were screened as potential TAVI candidates, 31 patients were initially recommended as appropriate for TAVI, and 20 of these 31 eventually underwent TAVI. Twenty-two patients underwent surgical aortic valve replacement (AVR), and 17 patients received only medical treatment. Patients who underwent TAVI and medical therapy were older than those who underwent surgical AVR (p<0.001). The logistic Euroscore was significantly highest in the TAVI group and lowest in the surgical AVR group (p=0.012). Most patients in the TAVI group (90%) and the surgical AVR group (91%) had severe cardiac symptoms, but only 47% in the medical therapy group had severe symptoms. The cumulative percentages of survival without re-hospitalization or all-cause death at 6 months for the surgical AVR, TAVI, and medical therapy groups were 84%, 75%, and 28%, respectively (p=0.007, by log-rank). CONCLUSION: TAVI was recommended in half of the potential candidates following a multidisciplinary team approach and was eventually performed in one-third of these patients. One-third of the patients who were initially considered potential candidates received surgical AVR with favorable clinical outcomes.

PURPOSE: The adverse effects of obesity on short-term surgical outcomes after laparoscopic colorectal surgery have been reported. However, the influence of obesity on long-term oncological outcomes after laparoscopic surgery in Asian patients has not been well understood. The aim of this study was to evaluate the effect of obesity on long-term oncologic outcomes in patients who underwent laparoscopic surgery for colorectal cancer. METHODS: Overall, 424 consecutive patients who underwent laparoscopic resection for colorectal cancer between January 2005 and July 2012 were included in this retrospective study. Patients were classified as non-obese (body mass index [BMI] <25.0 kg/m²) and obese (BMI ≥25.0 kg/m²) according to the categories proposed by the International Obesity Task Force. A survival analysis was performed using clinicopathologic characteristics, including obesity. RESULTS: Of the 424 patients, 325 (76.7%) were classified as non-obese and 99 (23.3%) as obese. The clinicopathologic characteristics of the obese and non-obese groups were similar, except that there were more underlying comorbidities, a lower frequency of smoking, and fewer tumors in rectum in the obese group. Results of the multivariate analysis showed that older age, elevated serum carcinoembryonic antigen, high-grade histology, advanced tumor stage, and perineural invasion were associated with poorer disease-free survival and overall survival. Obesity was not significantly associated with disease-free survival (hazard ratio [HR], 1.196; 95% confidence interval [CI], 0.686~2.086; p=0.528) or overall survival (HR, 1.156; 95% CI, 0.584~2.289; p=0.677). CONCLUSION: Laparoscopic surgery for colorectal cancer seems to be safe and feasible for obese patients in terms of long-term oncologic outcomes.

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) is now considered as an alternative treatment option for severe aortic stenosis (AS) patients who cannot undergo surgical aortic valve replacement (AVR). CASE REPORT: We describe the first Korean case of transaortic TAVI with mini-sternotomy using CoreValve. A 83-year-old woman with severe AS and recent history of non-ST elevation myocardial infarction was referred to our institution for TAVI intervention. There was no amenable peripheral vascular access for transfemoral or trans-subclavian approach. Considering the relatively high procedural risk of transapical approach in this patient, we performed transaortic TAVI with mini-sternotomy. CONCLUSION: The present case suggests transaortic approach may be an effective and safe strategy for TAVI in high risk severe AS patients without eligible femoral or subclavian access routes.

Transcatheter aortic valve implantation (TAVI) is indicated as an alternative treatment modality to surgical aortic valve replacement for high risk patients. The standard retrograde approach through the femoral artery is not feasible in the case of unfavorable iliofemoral anatomy or severe peripheral arterial disease (PAD). However, patients with aortic stenosis (AS) have a higher prevalence of for PAD because both diseases are consequences of atherosclerotic degenerative changes. Transsubclavian, transapical, and direct access to the ascending aorta by thoracotomy are alternative routes for the TAVI procedure. In this report, we present the first Korean patient with symptomatic severe AS and bilateral iliofemoral artery disease who was successfully treated with TAVI using a CoreValve (Medtronic, Minneapolis, MN, USA) by transsubclavian approach.
