Self-expanding metallic stent insertion has been widely applied for the palliative treatment of malignant esophageal strictures. Although it is known as an easy, safe, and effective procedure, complications are well known and include things such as stent migration and esophageal stent occlusion caused by tumor ingrowth. However, metallic stent fractures have been rarely reported in the esophagus, especially for nitinol stents. We report a case of a stent fracture associated with migration in a patient with a malignant esophageal stricture near the gastroesophageal junction. It is highly probable that the stent fracture was due to chemical erosion of the stent caused by gastric juice.

Elastofibroma dorsi is a rare, slow-growing, ill defined soft tissue tumor that's typically found between the inferior scapula and chest wall. The characteristic findings on ultrasonography, MRI and CT usually allow the correct diagnosis and so prevent unnecessary surgical procedure. We experienced a case of bilateral elastofibroma dorsi in an 87-year-old man, and we report on this case along with a review of the literature.

OBJECTIVES: Apoptosis may play a major role in determining the growth and progression of the tumors. Certain oncogenes and tumor supressor genes are known to modulate apoptosis. The aim of study was to investigate whether apoptosis is related to the degree of differentiation, MIB-1 indicies, and expression of mutated p53 and bcl-2 in cervical neoplasms. MATERIALS AND METHODS: We examined 57 samples of normal, premalignant(i.e. mild, moderate and severe dysplasia and carcinoma in situ), malignant cervical tissue to evaluate whether differences in the apoptotic activity. Apoptotic cells and bodies were visualized by 3' end labelling. Simultaneously, quantitative immunostaining was performed for bcl-2 and p53, two known regulators of apoptosis. RESULTS: The cell proliferation index as determined by MIB-1 immunohistochemistry increased with progression from normal to cervical intraepithelial neoplasm and invasive cancer. The apoptotic index(AI) also increased with grade of lesion and was significantly associated with cell proliferation. However, the extent of apoptosis did not correlate with the expression of p53 and bcl-2. CONCLUSIONS: These results suggest that the elevation of AI in cervical neoplasm is associated with cell proliferation activity but is independent of the expression of p53 and bcl-2. It is likely that the effects on apoptosis of bcl-2 and p53 are countered by those of other oncogene products and/or additional factors that regulate apoptosis in vivo.

The absence of the inferior vena cava is an uncommon congenital anomaly that has recently been identified as an important risk factor contributing to the development of deep venous thrombosis. Congenital agenesis of the right hepatic lobe is a rare anomaly which is found incidentally in radiologic examinations. We present a case of a congenital absence of the infrarenal inferior vena cava, combined with agenesis of the right hepatic lobe in a 62-year-old man presented with symptoms of deep venous thrombosis.

Because nonspecific colonic ulcer is an unusual condition and varies markedly in clinical presentation and course, preoperative clinical diagnosis of nonspecific colonic ulcer is very difficult, But now, preoperative clinical diagnosis can he made by advent of colonofiberscopy. And, it is very important to diagnose this disease early, because late diagnosis make a poor prognosis. We report a case of nonspecific colonic ulcer diagnosed by repeated colonofiberscopy and treated with surgery.

BACKGROUND AND OBJECTIVES: It was reported that external nasal dilators (ENDs) can reduce snoring and obstructive sleep apnea (OSA) in white people by dilating the nasal valve area and then, improving nasal breathing. However, there are no available data on Asians, whose geometry of nasal cavities is different from that of white people. The aim of this study is to evaluate the effects of ENDs on snoring and OSA in Korean adults. MATERIALS AND METHODS: Twelve simple snorers (3 female and 9 males, aged 19 to 44 years) and 35 OSA patients (35 males, aged 22 to 65 years) without nasal diseases were included in this study. Polysomnography including measurement of snoring intensity was performed at two separate nights, one with and the other without an END. Averaged maximum snoring intensity, apnea index (AI), respiratory disturbance index (RDI), ratio of deep sleep (stage 3 and 4) to total sleep time, and minimum arterial oxygen saturation (SaO2) with and without an END were measured and compared. RESULTS: Snoring intensity was reduced in 6 (50.0%) of 12 simple snorers and 16 (45.7%) of 35 OSA patients. In overall, snoring improved significantly in both groups. In OSA patients, AI and RDI improved significantly, but ratio of deep sleep time and minimum SaO2 did not. There were no significant correlations between change of snoring intensity and change of AI or RDI in OSA patients. CONCLUSION: These results suggest that ENDs are helpful to improvement of snoring and respiration during sleep, but the sleep stages remain almost unchanged by ENDs in Korean adults with snoring and/or OSA.

BACKGROUND: Genistein and daidzein are two major soybean isoflavones. They have received increasing attention because of their possible roles for cancer prevention. However, their mechanisms of action and molecular targets on the human colon cancer cells are not fully understood. METHODS: Human colon cancer HCT-116 cells were treated with genistein and daidzein to investigate their effects on the cell growth and this was analyzed with MTT assay. TUNEL assay and Hoechst33342 stain were carried out to identify apotosis. RESULTS: Daidzein was able to inhibit cell proliferation and induce apoptosis of the HCT-116 cells, but genistein didn't affect the cell growth. The ER antagonist ICI182780 didn't attenuate the antiproliferative and proapoptotic effects of daidzein: this means the effect of daidzein on the HCT-116 cells may not be dependent on the ER pathway. The other soybean isoflavone, genistein, attenuated the effects of daidzein on the HCT-116 cells and its mechanism should be elucidated. CONCLUSIONS: These data suggest that daidzein may act as a preventive agent on human colon cancer, and its mechanism of action doesn't involve the ER-dependent pathway.

OBJECTIVE: While the prognostic factors of survival for patients with hepatocellular carcinoma (HCC) who underwent transarterial chemoembolization (TACE) are well known, the clinical significance of performing selective TACE for HCC patients has not been clearly documented. We tried to analyze the potential factors of disease-free survival for these patients, including the performance of selective TACE. MATERIALS AND METHODS: A total of 151 patients with HCC who underwent TACE were retrospectively analyzed for their disease-free survival (a median follow-up of 23 months, range: 1-88 months). Univariate and multivariate analyses were performed for 20 potential factors by using the Cox proportional hazard model, including 19 baseline factors and one procedure-related factor (conventional versus selective TACE). The parameters that proved to be significant on the univariate analysis were subsequently tested with the multivariate model. RESULTS: Conventional or selective TACE was performed for 40 and 111 patients, respectively. Univariate and multivariate analyses revealed that tumor multiplicity, venous tumor thrombosis and selective TACE were the only three independent significant prognostic factors of disease-free survival (p = 0.002, 0.015 and 0.019, respectively). CONCLUSION: In our study, selective TACE was a favorable prognostic factor for the disease-free survival of patients with HCC who underwent TACE.
