Pseudopolyps represent discrete areas of mucosal inflammation and regeneration that are seen in a variety of inflammatory bowel disease including ulcerative colitis and Crohn's disease. These polyps are typically short, measuring less than 1.5 cm in height. Rarely, localized giant pseudopolyposis can occur, i.e., a collection of larger inflammatory pseudopolyps giving rise to a mass lesion within the colon. The most serious problem concerned with pseudopolyposis is a confusion with carcinoma. We experienced a case of localized giant pseudopolyposis causing partial large bowel obstruction. Right hemicolectomy was done for a preoperative diagnosis of ascending colon carcinoma. The resected specimen contained a circumferential lesion, which was composed of numerous interconnecting cylindrical villi, measuring 12 cm in length and 3 cm in height. Microscopically, these polypoid lesions were inflammatory pseudopolyps. Several deep fissure-like ulcerations were noted with multifocal microabscess, lymphoid hyperplasia and an area of noncaseating granuloma.

When coexistence of carcinoma with similar histologic type is present in female genital tract, it is difficult to differentiate independent primary tumor from metastasis. Most of them are endometrial and ovarian tumors, but coexistence of uterine cervical and ovarian tumor with similar histologic type is rare. We experienced an independent primary tumor of ovarian mucinous cystadenocarcinoma associated with mucinous adenocarcinoma of uterine cervix. The patient was a 50-year-old woman. She had a lower abdominal mass which was detected as a huge cyst on ultrasonography. Although the ovarian lesions were bilateral, features that preferred to consider independent primary tumor are listed as; absence of lymphatic or vascular invasion, absence of ovarian surface implant, superficial invasion of cervical tumor, absence of tumor in abdominal cavity, and disease free follow-up after removal of the tumor.

PURPOSE: Having been disappointed with standard anticoagulation therapy for acute deep vein thrombosis (DVT) in lower extremity, we started catheter-directed thrombolytic therapy. And the aim of this study was to evaluate the effects on venous function of catheter-directed thrombolytic therapy by noninvasive venous tests such as Air plethysmography (APG) and duplex ultrasonography. METHOD: 36 patients with DVT of less than 3 weeks after development into two groups according to treatment modality:Group 1; catheter-directed thrombolysis with Urokinase followed by low-molecular weight heparin (LMWH) and coumadin therapy (n=19, men; 11, women; 8, mean age 47.6 years), Group 2; conventional anticoagulation with LMWH followed by coumadin therapy (n=17; men; 12, women; 5, mean age 47.1 years). The results of lytic therapy were examined by complete phlebography on time of removal of catheter. The location and extent of thrombotic changes were followed-up with duplex scan and venous function was examined with APG. RESULT: Complete clot resolution by lytic therapy was obtained in 12 cases out of 19 cases (63.2%) in Group 1. The residual thrombi at follow-up around 1 year were detected in 4 cases in Group 1, in 11 cases in Group 2. APG parameters that were significantly different (P<0.05) between the two groups were the venous filling index:(Group 1; 1.63+/-1.36 ml/sec, Group 2; 2.66+/-1.58 ml/sec), residual volume fraction (Group 1; 27.54+/-17.40%, Group 2; 49.19+/-20.45%) and outflow fraction (Group 1; 37.79+/-7.05%, Group 2; 32.36+/-6.31 %). The parameters of APG and ultrasonography in Group 1 revealed lesser degree of reflux and smaller amount of residual thrombi. CONCLUSION: Catheter-directed thrombolytic therapy shows better results in complete resolution rate of the acute DVT, reducing remnant thrombi, and preserving venous function such as venous filling index, residual volume fraction and outflow fraction. APG and duplex scanning seem to be useful methods for a complete follow-up evaluation of limbs with DVT.

Surgical intervention in the posterior maxillary region requires detailed knowledge of maxillary sinus anatomy and the possible anatomical variations. This study evaluated the incidence, location of maxillary sinus septa by using radiographic (panoramic radiography and computed tomography) findings and comparison of panoramic radography with CT in antral anatomical variation. This study was based on data from 70 sinuses in partial dentate maxilla. The sample consisted of 61 patients(25 women and 36 men, with ages ranging between 19 and 77 years and a mean age of 49.4+/-11.3 years) who were being treatment-planned to receive implant-supported restorations. First, the panoramic images were examined for the presence of antral septa by radiologist and examiner who don't know about CT findings. And incidence of antral septa was evaluated using an axial plane of CT image. The incidence of septa was compared between panoramic radiography and CT. The accuracy of the incidence was compared between radiologists and dentists. A total of 20 septa were found in 70 sinuses on CT image and the prevalence of one or more septa per sinus was found to be 28.6%. The assumed incidence of septa on panoramic radiography was 27.6%+/-2.2% in radiologist and 31.9%+/-5.8% in dentists. Erroneous diagnosis rate was 11.42% in radiologist and 15.96% in dentists. 40% of antral septa were located in the anterior(premolar) region, 30% of septa were located in the middle(first molar) and posterior(second molar) region separately. Prior to implant placement, it seems appropriate to consider panoramic radiography as a standard radiographic examination and periapical radiographs may be used to complete the findings in regions not sharply depicted in the panoramic radiograph. And cross-sectional imaging should be used in sites with severe bone loss and close proximity of the maxillary sinus.

PURPOSE: Studies concerning the relationship between gene polymorphisms and potentially implicated cardiovascular disease have produced conflicting findings, in part due to differences in ethnic background between populations. These led us to evaluate the impact of polymorphisms in the ACE and E-selectin genes on peripheral artery atherosclerosis in a Korean population. METHODS: We studied 92 male patients (median age: 65.9, range: 48~82) with severe peripheral atherosclerosis documented by angiography and ABI (ankle brachial index). The control group comprised 290 healthy persons (male 216, female 64, median age 61.3, range 20~90) without symptoms for peripheral vascular disease. The blood samples were stored at -20oC until DNA was ready to be extracted. The inorganic procedure for DNA extraction was based on the method described by Miller et al. The ACE and E-selectin polymorphisms were detected by polymerase chain reaction (PCR) amplification. RESULTS: The distribution of ACE genotypes of the patient group was as follows: II, 34 (37.0%); ID, 46 (50.0%); and DD, 12 (13.0%). It was not significantly different from that of the control subjects: II, 104 (37.1%); ID, 133 (47.6%); and DD, 43 (15.3%) (P=0.80). The allele frequencies of the patient group were as follows: I, 114 (62.0%); and D, 70 (38.0%). It was not significantly different from that of the control subjects: I, 341 (60.9%); and D, 219 (39.1%) (P= 0.80). The frequencies of E-selectin genotypes in the patient group were as follows: Ser/Ser 85 (93.4%); Ser/Arg, 6 (6.6); and Arg/Arg, 0 (0%). It was not significantly different from that of the control subjects: Ser/Ser, 262 (93.6%); Ser/Arg, 18 (6.4%); and Arg/Arg, 0 (0%) (P=0.95). In addition, the allele frequencies of the patient group were as follows: Ser, 176 (96.7%); and Arg, 6 (3.3%). It was not significantly different from that of the control subjects: Ser, 542 (96.8%); and Arg 18 (3.2%) (P=0.95). CONCLUSION: The I/D polymorphism of the ACE gene and E-selectin S128R polymorphism were not significantly different between the atherosclerotic patient group and the normal control group in Koreans.

Persistent sciatic artery (PSA) is a continuation of the internal iliac artery into the popliteal-tibial vessels and this structure provides the major blood supply to the lower limb bud during early embyrologic development, Its remnants participate in the formation of the inferior gluteal, deep femoral, popliteal, peroneal and pedal vessels. When the femoral artery develops, the PSA then involutes. In rare circumstances it persists and so provides the only major blood supply to the lower limb. The PSA was first reported by Green in 1832 and until now, only about 100 cases have been reported in the world literatures. This rare vascular anomaly is associated with aneurysmal formation in 15% to 46% of cases and it has a bilateral location in 22% of PSA cases. In more than 40% of cases, PSA is asymptomatic. When present, such non-specific symptoms as gluteal pain and painful buttock mass are presented. However, the most frequent clinical finding is lower limb ischemia because in 25% of such cases, the presented symptoms are limb threatening. We describe here the case of a 54 year-old female affected with PSA occlusion, and she was treated with a combination of thrombolysis and thromboembolectomy.
