PURPOSE: The major source of acute peripheral arterial occlusion has been embolization from the heart. However overall improvement in medical care have increased life spans, resulting in significant increase in the incidence of systemic atherosclerosis and thrombotic occlusion of peripheral vessels. Recently, occlusion from in situ thrombosis has surpassed occlusion from embolization as the major cause of acute arterial occlusion. The introduction of the balloon catheter technique in 1963 dramatically simplified the technical aspect of surgical therapy for acute arterial occlusion and it became the main modality of the therapy. Recently, numerous reports have documented increased identification of intraluminal defects after arterial surgery using angioscopy as compared with those using intraoperative arteriography, and for this reason, the use of intraluminal angioscopy has grown in popularity. METHODS: We analyzed clinical characteristics and treatment results in patients with acute arterial occlusion. The variables studied include location, etiology, time interval from occurrence of occlusion to performance of thromboembolectomy. RESULTS: There were 41 men and 4 women and most prevalent age group was in 7th decades. The causes of acute arterial occlusion were embolism in 21 cases (46.7%), thrombosis in 24 cases (53.3%). The primary source of embolism was heart in 20 cases as a result of ischemic heart disease (n=11, 52.4%) and atrial fibrillation (n=9, 42.9%). Two patients in embolic group died of cardiogenic shock and were in shorter duration group (<24 hours). Iliac arterial occlusion group was associated with highest amputation rate (23.1%). Amputation rates were 12.5% for thromboembolectomy performed within 24 hours of onset of symptoms, and 17.4% when performed after 48 hours. We used angioscopic technique in limited cases of 5 patients to detect residual thrombus, intimal flap and other intraluminal defects. CONCLUSION: To improve outcome, early diagnosis and early treatment are essential. Direct visualization of the arterial lumen with angioscopy during thromboembolectomy procedure would provide a more reliable method of assessing luminal morphologic characteristics than angiography alone.

PURPOSE: To evaluate the results of autologous chondrocyte implantation with a concomitant injury. MATERIALS AND METHODS: Sixty-seven chondral defects (39 cases, 36 patients), which were treated with autologous chondrocyte implantation, were analyzed with a minimum follow-up of 2 years. The cases were divided into the following five groups: 4 cases of a single chondral defect (group I), 3 cases of multiple chondral defects (group II), 5 cases of osteochondritis dissecans (group III), 9 cases of a single chondral defect with a concomitant injury (group IV), and 18 cases of multiple chondral defects with a concomitant injury (group V). The clinical outcomes were evaluated using the International Knee Documentation Committee (IKDC) subjective and objective scores and the International Cartilage Repair Society (ICRS) functional evaluation system. Arthroscopic examinations were performed on 12 cases and 21 chondral defects. RESULTS: The mean IKDC subjective score was 39.8 preoperatively, which improved to 64.1 postoperatively, and the IKDC objective score was C in 54% and D in 46%, which improved to A in 74%, B in 23% and C in 3%. The ICRS functional evaluation system was III in 82% of cases, and IV in 18% preoperatively, which improved to I in 15% and II in 85%, postoperatively. At the arthroscopic evaluation, the results of the ICRS system were I in 9%, II in 67%, and III in 24%. There was no significant difference between the single chondral defect and chondral defects with a concomitant injury. CONCLUSION: In the treatment of the multiple chondral defects with a concomitant injury, autologous chondrocyte implantation produced similar excellent clinical results to those of a single chondral defect.

Fibroadenoma is a rare lesion of the vulva. It has been proposed that the origin of the tissue is either ectopic breast tissue or vulvar mammary-like glands (MLG). We report a case of vulvar fibroadenoma in a 33-year-old woman with a right vulvar mass presenting clinically as vulvar cyst. The cut surface of the tumor showed a white and homogenous appearance that was 2.5 cm in maximum dimension. Microscopically, the lesion was well-circumscribed but non-encapsulated. It revealed nodular, glandular and stromal proliferation, consistent with fibroadenoma of breast. Immunohistochemical staining for the estrogen receptor and progesteron receptor revealed nuclear positivity in the epithelium. Smooth muscle actin confirmed the presence of a myoepithelial cell layer. Staining for pancytokeratin showed epithelial cytoplasmic positivity.

BACKGROUND: There is strong evidence for the efficacy of stroke unit (SU) care, which has become a common practice in other developed countries but is available only in a small number of centers in Korea. This late introduction of SU care in Korea can be at least partly attributed to doubts about its benefits on patient outcomes compared to general ward (GW) care in our routine practice. METHODS: Based on a prospective stroke registry, we identified 1,300 acute stroke patients hospitalized in either SUs (n=195) or GWs (n=1,105) from January 2004 to June 2008. Clinical outcomes such as fatality and disability rates were compared using propensity score matching in the total cohort. Additional statistical adjustments were performed using stepwise logistic regression analyses with the backward elimination method for potential confounders. RESULTS: The baseline characteristics did not differ significantly between patients admitted to SUs (n=195) and their matched controls (n=386). The 3-month dependency rate was 17.4% in SUs and 21.0% in GWs (p=0.31), and the case fatality rates were 1.5% and 8.0% (p<0.001), respectively. Adjusted odds ratios for SU care were 0.49 for dependency (95% confidence interval [CI]=0.22-1.08) and 0.17 for death (95% CI=0.04-0.83). CONCLUSIONS: This study showed that SU care reduces fatality rates and improves functional outcomes, which indicates the need to implement more SUs in Korea.

The squamous cell carcinoma of ovary is very rare in the ovarian malignancy. The majority of squamous cell carcinomas of ovary are considered to be associated with mature cystic teratoma, Brenner tumor and malignant degenerated endometriosis. Therefore, pure ovarian squamous cell carcinoma is extremely rare. The pathogenesis, prognosis and proper treatment guideline of this malignancy are still unknown, because of it's rarity. Recently we experienced a case of primary squamous cell carcinoma without previously commented disease condition. After nearby cytoreductive surgery, postoperative chemotherapy with radiotherapy has been undergoing. We report this malignancy with a brief review of literature.

Primary squamous cell carcinoma of the endometrium is very rare. In 1928 Flumann suggested three criteria for diagnosis: (1) no coexisting endometrial adenocarcinoma, (2) no connection between the endometrial squamous cell carcinoma and squamous epithelium of the cervix, and (3) no cervical squamous cell carcinoma. In 1975, the World Health Organization (WHO) updated Flumann's criteria by adding that the tumor must contain clear evidence of squamous differentiation, such as the presence of intercellular bridges and/or keratin. Most patients with endometrial squmamous cell carcinoma have had poor prognosis regardless of their stages of disease or treatment. In this report we present the clinical and pathological findings of a case of a primary squamous cell carcinoma that developed in the endometrial cavity of a 65-year-old patient with a review of the concerned literatures.

OBJECTIVE: To evaluate the effects of rehabilitation-start critical pathway (Rehab-CP) based on modified Rankin scale (mRS) on stroke outcomes. METHOD: We compared stroke outcome between before and after the carrying into effect of Rehab-CP by retrospective medical record review. First-onset stroke patients admitted to neurology department, and transferred to rehabilitation department were included in the analysis. Hospital length of stay (LOS), home discharge rate, functional outcome such as mRS, Brunnstrom stage, Korean version of modified Barthel index, Fugl-Meyer scale, mini-mental status examination, Berg Balance scale at discharge and 3 months after onset were analyzed. RESULTS: Thirty-nine patients before the commencement of Rehab-CP and 46 patients after the Rehab-CP were compared. Length of stay in neurology department were 2.5 days shorter in after Rehab-CP group as compared to before Rehab-CP group (p=0.056) and total LOS were 1.9 days shorter in after Rehab-CP group (p=0.485), although this did not reach statistical significant difference. There were no differences in home discharge rate, and other functional outcomes between two groups (p>0.05). CONCLUSION: Rehabilitation-start CP based on mRS may decrease LOS without affecting functional outcome, and this result primarily comes from the shortening of stay in neurology department before transfer to rehabilitation ward.

BACKGROUND AND PURPOSE: Health-related quality of life (HRQoL) is a multidimensional concept that signifies a subjective evaluation of perceived health; hence, it has gained wide acceptance in geriatrics. However, its application has not been tested in patients with post-stroke cognitive impairment with no dementia (PSCIND). We investigated whether PSCIND interferes with HRQoL measured by EQ-5D, compared the findings to those of healthy people with normal cognition, and evaluated the influence of each cognitive domain on this score. METHODS: In total, 1,528 subjects were identified who had undergone neuropsychological assessment using the 60-min protocol of the Korean version of Vascular Cognitive Impairment Harmonization Standards, EQ-5D, and magnetic resonance imaging at the stroke prevention clinic. Fifty PSCIND patients were matched to 50 post-stroke dementia (PSD) patients and 50 normal age- (+/-3 years) and sex-matched controls. The effects of PSCIND, PSD, and control groups upon the EQ-5Dindex score were tested by generalized estimating equation modeling. RESULTS: Estimated means+/-standard errors of EQ-5Dindex scores were as follows: 0.94+/-0.06 (control group), 0.86+/-0.08 (PSCIND group), and 0.61+/-0.32 (PSD group); and the difference among the three groups was statistically significant (P<0.0001). Pairwise comparisons showed that EQ-5Dindex scores in the PSCIND group differed from those in the PSD and control groups (both P<0.01). No cognitive domain was specifically associated with EQ-5Dindex scores after adjusting for functional status. CONCLUSIONS: This study shows that PSCIND may interfere with the quality of life in stroke victims.
