PURPOSE: The purpose of this study is to describe the anglographic findings of collateral vessels in cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of anglographic assessmant needed before embolization. MATERIALS AND METHODS: We retrospectively reviewed 10 cervicofacial vascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous realformation with carotid cavernous fistula. The previously ligated arteries are proximal external carotid artery (n=5), branches of external carotid artery (n=2) and common carotid artery (n=3). Common carotid artery or internal carotid artery (n=9), vertebral artery (n=5), ipsilateral external carotid artery (n=4), contralateral external carotid artery (n=5), costocervical trunk (n=2), thyrocervical trunk (n=2) were assessed by conventional angiography. Angiography of both carotid and vertebral arteries was performed in 5 cases. RESULTS: The collateral vascular channels were inferolateral trunk of internal carotid artery (n=8), vertebral artery (n=5), contralateral external carotid artery (n=5), ipsilateral external carotid artery (n=4), deep cervical artery (n=2) and ascending cervical artery (n=l). Embolizations were performed in 9 cases with operative cannulation(n=4), embolization via collateral branches of ipsilateral external carotid artery (n=l), embolization via collateral branches of contralateral external carotid artery (n=3) and balloon occulusion via direct puncture (n=l). CONCLUSION: The collateral channels in cervicofacial vascular lesions with previouly ligated carotid artery were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervical artery and ascending cervical artery on angiography. Complete anglographic assessment of possible collateral channels is mandatory for the effective and safe embolization.

Malignant epithelial neoplasm usually occurs in postmenopausal women, with less than 10% of cases occurring in women under the age of 20. In patients below this age, the majority of ovarian tumors are of germ cell origin and malignant ovarian epithelial tumors are uncommon. We report US & CT imaging in a case of mucinous cystadenocarcinoma in a 17-year-old nullipara who complained of amenorrhea for 45 days and a palpable mass.

PURPOSE: Urethral diverticulum in female can be easily detected by physical examination but sometimes the diagnosis can be difficult. Difficulty in prompt diagnosis and treatment arises from the constellation of nonspecific urinary symptoms. Furthermore, treatment may be unsuccessful and result in persistent or recurrent troublesome symptoms. We reviewed our experience with managing symptomatic diverticula for the prompt diagnosis and the definite cure. MATERIALS AND METHODS: We reviewed 33 cases of urethral diverticulectomy performed at our institution for the last 10 years. At presentation patient age ranged from 24 to 57 years (mean 39 years). Two women (6.0%) were nulliparious and average parity was 1.9 births (0-5). Investigations included voiding cystourethrogram, excretory urogram, cystourethroscopy, urodynamic studies and recently transvaginal ultrasound. Transvaginal diverticulectomy was performed using a 3-layer closure (urethral wall, periurethral fascia, vaginal wall) in all women. Concomitant bladder neck suspension was performed in 1 woman. RESULTS: Voiding cystourethrography adquately demonstrated the diverticulum in 11 of the 14 women (78.6%). Transvaginal ultrasound was performed in 21 women and identified the diverticulum in 19 women (90.5%). Of 33 women 32 were cured (97.0%) and secondary transvaginal diverticulectomy was performed for incomplete excision of diverticulumin in 1 woman. According to McGuire's classification 13 cases were classified as pseudodiverticulum which is a mucosal herniation through a periurethral fascial defect, and the rest 20 cases as true diverticulum. This classification had no influence on the surgical success rate. Complications of diverticulectomy included 2 cases of de novo stress urinary incontinence and 1 urethrovaginal fistula. CONCLUSIONS: Preoperative radiographic imaging helps to delineate diverticular anatomy and transvaginal ultrasound is useful test because of absence of ionizing radiation, reduced risk of infection, less invasiveness and higher detection rate than voiding cystourethrogram. With meticulous excision and 3-layer repair, definitive cure can be achieved with a single operation.

Although Crohn's disease is usually found in the ileum and colon, it can be located in the whole gastrointestinal tract from the oral cavity to the anus. The frequency of gastroduodenal Crohn's disease is rare and is reported to range between 0.5% and 4.0% in Crohn's disease. And when Crohn's disease does involve the upper gastrointestinal tract, there is nearly always concomitant disease in the small bowel and colon. Very rarely, isolated Crohn's disease of the stomach and duodenum may occur. Definite diagnosis requires histologic confirmation, however, endoscopic biopsies often fail to reveal granuloma. Thus, if absence of definite histologic findings, combining clinical, radiologic and endoscopic findings suggest this condition. We experienced a first case of Crohn's disease confined to stomach and reported with review of the literature.

BACKGROUND: Autophagy is an important adaptive mechanism in normal development and in response to changing environmental stimuli in cancer. Previous papers have reported that different types of cancer underwent autophagy to obtain amino acids as energy source of dying cells in nutrient-deprived conditions. However, whether or not autophagy in the process of lung cancer causes death or survival is controversial. Therefore in this study, we investigated whether nutrient deprivation induces autophagy in human H460 lung cancer cells. METHODS: H460, lung cancer cells were incubated in RPMI 1640 medium, and the starved media, which are BME and RPMI media without serum, including 2-deoxyl-D-glucose according to time dependence. To evaluate the viability and find out the mechanism of cell death under nutrient-deprived conditions, the MTT assay and flow cytometry were done and analyzed the apoptotic and autophagic related proteins. It is also measured the development of acidic vascular organelles by acridine orange. RESULTS: The nutrient-deprived cancer cell is relatively sensitive to cell death rather than normal nutrition. Massive cytoplasmic vacuolization was seen under nutrient-deprived conditions. Autophagic vacuoles were visible at approximately 12 h and as time ran out, vacuoles became larger and denser with the increasing number of vacuoles. In addition, the proportion of acridine orange stain-positive cells increased according to time dependence. Localization of GFP-LC3 in cytoplasm and expression of LC-3II and Beclin 1 were increased according to time dependence on nutrient-deprived cells. CONCLUSION: Nutrient deprivation induces cell death through autophagy in H460 lung cancer cells.

BACKGROUND: Most lung cancer patients receive systemic chemotherapy at an advanced stage disease. Cisplatin-based chemotherapy is the main regimen for treating advanced lung cancer. Recently, autophagy has become an important mechanism of cellular adaptation under starvation or cell oxidative stress. The purpose of this study was to determine whether or not autophagy can occurred in cisplatin-treated lung cancer cells. METHODS: H460 cells were incubated with RPMI 1640 and treated in 5 micrometer or 20 micrometer cisplatin concentrations at specific time intervals. Cells surviving cisplatin treatment were measured and compared using an MTT cell viability assay to cells that underwent apoptosis with autophagy by nuclear staining, apoptotic or autophagic related proteins, and autophagic vacuoles. The development of acidic vascular organelles was using acridine orange staining and fluorescent expression of GFP-LC3 protein in its transfected cells was observed to evaluate autophagy. RESULTS: Lung cancer cells treated with 5 micrometer cisplatin-treated were less sensitive to cell death than 20 micrometer cisplatin-treated cells in a time-dependent manner. Nuclear fragmentation at 5 micrometer was not detected, even though it was discovered at 20 micrometer. Poly (ADP-ribose) polymerase cleavages were not detected in 5 micrometer within 24 hours. Massive vacuolization in the cytoplasm of 5 micrometer treated cells were observed. Acridine orange stain-positive cells was increased according in time-dependence manner. The autophagosome-incorporated LC3 II protein expression was increased in 5 micrometer treated cells, but was not detected in 20 micrometer treated cells. The expression of GFP-LC3 were increased in 5 micrometer treated cells in a time-dependent manner. CONCLUSION: The induction of autophagy occurred in 5 micrometer dose of cisplatin-treated lung cancer cells.
