PURPOSE: Prompt operative management of patients with peripheral artery embolism remains the treatment of choice for this malady. The clinical status of the limb, rather than the elapsed time from the onset of occlusion, was recently determined to be the best predictor of limb salvage. We investigated the clinical features, therapeutic modalities and treatment results of popliteal artery embolism compared with that of ilio-femoral artery embolism. METHODS: A retrospective review was carried out for 21 cases that were treated for lower extremity arterial embolism, from March 2000 to June 2006. The patients were classified into two groups; Group A (ilio-femoral artery embolism, n=11) and Group B (popliteal artery embolism, n=10). We analyzed the interval time from the onset of symptoms to starting treatment (the interval time), the degree of limb ischemia, the therapeutic modalities and the treatment results. RESULTS: The average interval time was 16.2+/-16.9 hours in the total 21 cases; the average interval time for Group A was 7.7+/-2.9 hours and that for Group B was 25.5+/-20.9 hours (P<0.05), and the incidence of severe limb ischemia (class IIb according to the SVS/ISCVS reporting standard) was 72.7% vs 20.0%, respectively (P<0.05). For the therapeutic modalities, surgical thromboembolectomy was performed in all cases of Group A and for 3 cases of Group B. Seven cases of Group B received radiologic intervention (3 cases percutaneous aspiration embolectomy only, and 4 cases of additional thrombolytic therapy). CONCLUSION: This study shows that the interval time for popliteal artery embolism is longer than that for ilio-femoral artery embolism. In other words, it is suggested that the symptomatic progression of popliteal artery embolism is slower than that of ilio-femoral artery embolism. Therefore, we can have more chances for variable therapeutic options such as surgical thromboembolectomy, percutaneous aspiration embolectomy and/or thrombolytic therapy in patients suffering with popliteal artery embolism.

PURPOSE: We analyzed the survival and failure patterns of cervix cancer patients treated with irradiation alone to evaluate our treatment method and to compare with the others. METHODS AND MATERIALS: Two hundred and twenty cervical cancer patients, Stage IB, IIA, and IIB who completed the planned treatment between May 1987 and December 1991 were analyzed retrospectively. The Stage IB patients were restaged to the Stage IB1 and IB2 by the recently revised FIGO classification. Patients were treated with a combination of external irradiation and the intracavitary brachytherapy. Determination of the tumor control was done at the time of 6 months postirradiation. The follow-up time was ranged from 3 to 115 months and the mean was 62 months and the follow-up rate was 93.6%(206/220). RESULTS: The overall 5-year survival rate of Stage IB1(N=50), IB2(N=15), IIA(N=58), and IIB(N=97) was 94%, 87%, 69%, and 56%, respectively. In the univariate analysis of prognostic factors,stage(0.00), initial Hg level (p=0.00), initial TA-4(tumor-associated) antigen level(p=0.02), initial CEA level(p=0.02), barrel-shaped tumor(p=0.02), whole cervical involvement (0.00), pelvic lymphadenopathy(LAP) in CT(p=0.04), and post-irradiation adjuvant chemotherapy(p=0.00) were statistically significant in survival analysis. In a while, multivariate analysis showed that the stage was the most powerful prognostic indicator and the post-irradiation chemotherapy factor also showed the statistical significance. The overall local control rate was 81% and by the stage, 100% in Stage IB1, 86.7% in Stage IB2, 84.5% in Stage IIA, and 68.1% in Stage IIB, respectively. The overall tumor recurrence rate was 15.5%(27/174) and by the stage, 8%(4/50) in Stage IB1, 0%(0/13) in Stage IB2, 22.4%(11/49) in Stage IIA, and 19.4%(12/62) in Stage IIB, respectively. CONCLUSIONS: We obtained the similar treatment results to the other's ones in early stage cervical cancer patients. But in Stage IIB, the local control rate was lower than that of the other institutes and also the survival was poorer. So it seems to be necessary to reevaluate the treatment method in advanced cervical cancer patients.

PURPOSE: The adjuvant postoperative radiotherapy has been usually applied to the patients with unfavorable prognostic factors after radical operation in early cervical cancer. We focused on the evaluation of the survival status and failure patterns of the patients with postoperative radiotherapy. MATERIALS AND METHODS: We retrospectively analyzed ninety patients with FIGO stage IB and IIA cervix cancer who received postoperative pelvic irradiation at Chonnam University Hospital between August 1985 and December 1988. Seventy-eight patients had adequate follow-up information for survival anlysis. Median follow-up time of these patients was 64 months. RESULTS: The 5 year overall and disease free survival rate of ninety patients was 80.0% and 80.2% respectively. The prognostic significance to the survival was determined by multivariate analysis. Adequacy of resection margin(p=0.005) and lymph node status(p=0.005) appeared to be independent prognostic factors. Recurrence occurred in 13 Patients, 5 in the pelvis and 8 at distant sites. He median time to recurrence was 19 months(range;3-39 months). The pelvic recurrence was more prevalent in the group of patients with adenocarcinoma, depth of stromal invasion more that 10mm and use of chemotherapy. The distant failure was more prevalent in the group of positive resection margin or positive lymph node with statistical significance. CONCLUSION: Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group in this analysis and should be considered as candidates for some form of adjuvant therapy.

STUDY DESIGN AND OBJECTIVE: Tumor necrosis factor-alpha(TNF-alpha), a key inflammatory mediator, has been demonstrated in spinal cord injury (SCI). However, the expression of TNF receptors following SCI remains to be identified. To elucidate the expressions of TNF receptor I (TNFRI), TNFRII, XIAP, and their function in SCI, in situ hybridization and RT-PCR were performed in a SCI model. MATERIAL AND METHODS: Sprague-Dawley rats were anesthetized with halothane and laminectomized at the level of the eleventh and twelfth thoracic vertebra. Using a modified New York University Impactor, SCI was induced by dropping a 10 gm weight from a height of 20 mm. The rod of the impactor had a constant circular surface, 3 mm in diameter. After induction of the injury, rats were placed in a temperature and humidity-controlled chamber overnight. RESULTS: The TNFRI gene was not detected in the control rats, but the TNFRII gene was expressed in the neurons in the control rats. The TNFRI gene expression was maximally increased in the spinal cord 1 day after the SCI; however, that of the TNFRII gene occurred 3 days after the SCI. In the white matter, both the TNFRI and TNFRII genes were increased in the oligodendrocytes 3 days after the SCI. The XIAP gene was increased in neurons of the gray matter 1 and 3 days after the SCI, but was not detected in the white matter after the SCI. CONCLUSION: Up-regulation of the expression of TNFRII occurs later than that of TNFRI in the spinal cord after a SCI. TNFR may be related to neuronal survival considering its similar expression pattern to that of XIAP. The results from these studies may lead to alternative therapeutic targets of TNF receptors in spinal cord injury, providing the basis for developing agonist and antagonist systems for TNF receptor subtypes and also for encouraging better strategies for the treatment of spinal cord disorders related to trauma.

Adult intussusception is a rare disease and it differs from childhood intussusception in its presentation, cause and treatment. Most of the cases have an underlying lesion within the intussusception that requires surgical resection. Making the diagnosis can be delayed because of the nonspecific and chronic symptoms, and many cases are diagnosed during performance of emergency laparotomy for treating the obstructive symptoms. A computed tomography (CT) scan is most useful for making the diagnosis of adult intussusception and is helpful in revealing the underlying lesion, although a barium enema can help to diagnose colonic intussusceptions. Surgical resection remains the recommended treatment for nearly all cases, but there is controversy about whether or not the intussusception should be initially reduced before resection. Gastrointestinal lipomas are rare benign tumors that can occur anywhere along the gut, and the small bowel is the second most common site for gastrointestinal lipomas after the colon. Intussusception of the ileum by a lipoma is very rare. We report here on a case of ileo-ileal intussusception that was caused by a lipoma of the ileum in a 35-year-old man who complained of abdominal pain of one week duration. The diagnosis of an ileo-ileal intussusception caused by a lipoma of the ileum was suspected preoperatively according to the typical CT findings, so we tried to initially reduce the intussusception during laparotomy. But manual reduction was impossible due to the edema of the lesion, and an ileum of some length had to be resected.

PURPOSE: The prognosis of patients with advanced non-small-cell lung cancer (NSCLC) is extremely poor. Many prospective randomized trials on patients with advanced NSCLC suggested systemic chemotherapy improves both the survival and quality of life. A phase II trial was conducted to evaluate the efficacy and safety profile of the combination chemotherapy of gemcitabine and cisplatin in advanced NSCLC. MATERIALS AND METHODS: Forty-four patients with locally advanced or metastatic NSCLC were enrolled. The patients received a cisplatin, 75 mg/m(2), infusion over 30 minutes on days 1, followed by a gemcitabine, 1, 250 mg/m(2), infusion over 30 minutes on days 1 and 8 every 3 weeks. RESULTS: The median age of the patients was 64 years (range: 27~75). Forty-one patients were assessable for response and toxicity analyses. The overall response rate was 53.6%, but with no complete remissions. The median time to progression was 5.6 months (range: 1~15.4). The median survival was 14.2 months (95% confidence interval (CI), 13.8~22.5). A total of 179 cycles were administered, with a median of 4 cycles of chemotherapy, ranging from 2 to 9 cycles. The most common hematological toxicities were NCI grades 3/4 neutropenia (24%) and thrombocytopenia (7.8%). The most common non-hematological toxicity was fatigue (42.4%). There were no life-threatening toxicity or treatment related mortalities. The median duration of follow up was 9.4 months, ranging from 1.6 to 30.3 months. CONCLUSION: In this trial, the combination of gemcitabine and cisplatin showed significant activity, with acceptable and manageable toxicities as a first-line regimen for patients with advanced NSCLC.

Green nail syndrome is characterized by greenish discoloration of the nail. It is caused by Pseudomas aeruginosa which is an aerobic gram-negative rod found in moist environment. The most common predisposing factors are frequent exposure to water and trauma history. Herein, we report two cases of green nail syndrome who developed greenish discoloration of finger nails, which were treated by systemic levofloxacin and gentian violet application.

Purpose: Although protein-induced vitamin K absence or antagonist II (PIVKA-II) has been used as a diagnostic tool for hepatocellular carcinoma (HCC), its prognostic value remains unclear. Methods: This was a nationwide multicenter study using the database of the Korean Liver Cancer Association. Patients with hepatitis B-related HCC who underwent liver resection as the first treatment after initial diagnosis (2008–2014) were selected randomly. Propensity score matching (1:1) was performed for comparative analysis between those with low and high preoperative PIVKA-II. Univariable and multivariable Cox proportional-hazards regression were used to identify prognostic factors for HCC-specific survival. Results: Among 6,770 patients, 956 patients were included in this study. After propensity score matching, the 2 groups (n = 245, each) were well balanced. The HCC-specific 5-year survival rate was 80.9% in the low PIVKA-II group and 78.7% in the high PIVKA-II group (P = 0.605). In univariable analysis, high PIVKA-II (>106.0 mAU/mL) was not a significant predictor for worse HCC-specific survival (hazard ratio [HR], 1.183; 95% confidence interval [CI], 0.76–1.85; P = 0.461). In multivariable analysis, hyponatremia of <135 mEq/L (HR, 4.855; 95% CI, 1.67–14.12; P = 0.004), preoperative ascites (HR, 4.072; 95% CI, 1.59–10.43; P = 0.003), microvascular invasion (HR, 3.112; 95% CI, 1.69–5.74; P < 0.001), and largest tumor size of ≥5.0 cm (HR, 2.665; 95% CI, 1.65–4.31; P < 0.001), but not preoperative high PIVKA-II, were independent predictors for worse HCCspecific survival. Conclusion Preoperative PIVKA-II is not an independent prognostic factor for HCC-specific survival after liver resection for hepatitis B-related HCC.

BACKGROUND: Pitted keratolysis is a superficial bacterial infection which usually affects the pressure bearing areas of the feet. Some bacterial organisms were identified as etiologic agents, including Corynebacterium species, Micrococcus species and Dermatophilus congolensis. However, in Korea, studies to prove the causative organisms have not been performed. OBJECTIVE: We performed this study to identify causative organisms of pitted keratolysis in Korea. METHOD: Twelve normal healthy men and 27 pitted keratolysis patients were enrolled. We cultured the scraped specimens of the stratum corneum and identified the cultured organisms. We compared the cultured organisms of pitted keratolysis group with those of control group. We also compared the distribution of cultured organisms in pitted keratolysis with and without tinea pedis. RESULT: Micrococcus species and Corynebacterium species were identified in pitted keratolysis group much more frequently than in normal control group. In most cases of pitted keratolysis combined with tinea pedis, the identified organisms were Micrococcus species. CONCLUSION: Micrococcus species and Corynebacterium species are thought to be the major causative organisms of pitted keratolysis in Korea. Micrococcus species might play a certain antagonistic role, especially in patients of pitted keratolysis with tinea pedis.
