PURPOSE: A laterally spreading tumor (LST) has its own characteristic features and growth pattern. Information about LST is scanty in Korea, therefore this study was designed in order to contribute to the literature. METHODS: In this study, 43 patients with LSTs were included. The diagnoses were made by colonoscopy in all cases. Treatment options included endoscopic resection, transanal excision, and surgical resection. In reviewing and analyzing the cases, we made a special emphasis on size, classification, histology, and treatment. RESULTS: The most frequent location was the rectum, followed by the sigmoid colon and the ascending colon in that order. Lesions smaller than 20 mm accounted for 69.8%. Granular homogeneous LSTs, 41.9%. Lesions larger than 20 mm, except granular homogeneous LSTs, showed an abrupt increase in malignancy rate. Tubular adenomas accounted for 65.1%. The overall malignancy rate was 20.9%, and the submucosal cancer rate, 9.3%. There were no malignancies in the granular homogeneous LSTs. The malignancy rate for the mixed-nodule type lesions was 33.3% (4/12), and the nongranular LSTs, 38.5% (5/13). Polypectomy was done in 37.2% of the lesions, endoscopic mucosal resection (EMR) in 16.3%, and endoscopic piecemeal mucosal resection (EPMR) in 16.3%. The overall endoscopic resection rate was 83.7% (36/43). EMR was applicable to lesions smaller than 20 mm, and EPMR to those larger than 20 mm. Transanal resection was done in 2 cases with lesions. Five cases were resected surgically. Four of them were submucosal invasive lesions, and one, a mucosal lesion which was wide and had initially been thought to be a submucosal cancer. There were two recurrences during the average 15-month follow-up period. The follow-up rate was 81.4% (35/43). Of these 2 recurring cases, one patient was treated endoscopically and the other, transanally. CONCLUSIONS: LSTs show different behavior depending on the endoscopic classification. Granular homogeneous LSTs are seldom larger than 30 mm and are good candidates for endoscopic treatment. The mixed-nodule type and the nongranular type show a marked predisposition to malignancy when they are over 20 mm, and nongranular-type LSTs have a higher rate of submucosal invasive cancers. Thus, in the cases of the mixed-nodule and nongranular types, careful consideration should be given for deciding between endoscopic treatment and surgical resection. Complete resection should be assured to prevent recurrence, and follow-up surveillance is required in all lesions for more than 3 to 5 years.

This study is performed to evaluate usefulness of dermal measurement of benzidine and benzidine based dye as one of the occupational exposure assessment method for these compounds. We selected one benzidine manufacturing factory and one dye manufacturing factory in Incheon area. Eleven workers were for benzidine manufacturing factory and twenty four for dye. We analyzed relationships among air level, amount on skin and concentration of urinary metabolites for these compounds. Airborne levels of benzidine and dye were measured by NIOSH 5509, 5013 methods. Amount of these compounds on skin was measured with skin wipe method. Concentration of benzidine metabolites in urine was measured by High Performance Liquid Chromatography after alkaline hydrolysis. The amount of benzidine on hand skin was 25.05( - 233.2) ng/ur, and the amount of the neck was 2.01 ( - 11.9) ng/cm2 in the benzidine dihydrochloride manufacturing factory. The amount of benzidine on hand and neck skin has positive correlation with concentration of urinary monoacetyl benzidine (r=0.644, p < 0.05) . The amount of benzidine based dye on hand skin was 55.75( - 457.7) ng/cm2, and the amount of the neck skin was 18( - 284.7) ng/cm in benzidine based dye manufacturing factory The amount of dye on hand and neck skin has positive correlation with concentration of urinary benzidine for dye workers (r=0.467, p < 0.05). When assessing the exposure of workers who deal with benzidine, the amount of benzidine on skin should be measured for an accurate exposure assessment.

6.Ureterosciatic hernia causing obstructive uropathy successfully managed with minimally invasive procedures

Ureterosciatic hernia is extremely rare. In ureteral herniation, ureter prolapses occur through either the greater or lesser sciatic foramen. Atrophy of the piriformis muscle, hip joint diseases, and defects in the parietal pelvic fascia are predisposing factors for the development of ureterosciatic hernia. Most symptomatic patients have been treated surgically, with conservative treatment reserved only for asymptomatic patients. To the best of our knowledge, long-term follow-up outcomes after ureterosciatic hernia management are sparse. In this paper, we report the case of a 68-year-old woman who presented with colicky left abdominal pain. After computed tomography (CT) scan and anterograde pyelography, she was diagnosed ureterosciatic hernia with obstructive uropathy. We performed ureteral balloon dilatation and double-J ureteral stent placement. After this minimally invasive procedure, CT scan demonstrated that the left ureter had returned to its normal anatomical position without looping into the sciatic foramen. The patient remained asymptomatic with no adverse events 7 years after the minimally invasive procedures. This brief report describes ureterosciatic hernia successfully managed with minimally invasive procedures with long-term follow-up outcomes.

BACKGROUND: The effect of arterial carbon dioxide tension (PaCO2) during ischemia and reperfusion has been a controversial issue. In this study, the effect of PaCO2 during ischemia and reperfusion was evaluated by 31P magnetic resonance spectroscopy (MRS). METHODS: Incomplete global cerebral ischemia was induced by ligation of carotid artery under lowered mean blood pressure (mean blood pressure= 40 mmHg) for 30 minutes followed by 2 hours of reperfusion. Eighteen cats were divided into 3 groups: For group 1 (n=6) (control group), animals were subjected to normocarbia (PaCO2=28~33 mmHg) during ischemia and reperfusion, for group 2 (n=6), animals were subjected to hypocarbia (PaCO2=18~23 mmHg) during ischemia and reperfusion, and for group 3 (n=6), animals were subjected to normocarbia during ischemia and hypocarbia during reperfusion. RESULTS: For group 1, the energy metabolism measured by [PCr/Pi] was recovered about 74.7 6.4%. For group 2, the energy metabolism failed to be completely recovered by 120 minutes of reperfusion (69.3 7.3%), whereas for group 3, the energy matabolism was completely recovered by 120 minutes of reperfusion (97.6 2.4%). There were statistically significant differences between group 1 and group 3 (p<0.05). The changes in pH were not significantly different among the groups. CONCLUSION: In this study, a condition of hypocarbia during reperfusion seems better for the energy metabolism after incomplete global ischemia of cats.

In this study, the ontogeny of the dopamine D1 and D2 receptors on fetal rat retina was investigated by using in situ hybridization technique. The expression of the D1 and D2 receptor mRNAs showed different pattern of appearance, distribution and density. At gestational day(GD) 13.5, D1 receptor was first detected in neuroepithelium of the retina. Both D1 and D2 receptors were detected at GD 15.5 in the ventricular layer and ganglion cell layer of developing retina of the rat, and D1 receptor showed more strong density than that of D2 receptor. At GD 17.5, Both D1 and D2 receptors were detected in the ganglion cell layer, ventricular layer and pigment epithelium. The labelling density of D1 receptor was higher than that of D2 receptor. At GD 19.5, both D1 and D2 receptors were additionally detected in the optic nuclear layer and plexiform layer. These results imply that D1 and D2 receptor may mediate different important function of the retina.
