A case of dermatitis herpetiformis resembling atopic dermatitis is reported. The patient is 45 year-o1d male, who 6 months ago developed the pruritic erythematous vesicular eruptions on the left side of back and it gradually spread to the margin. He was treated with steroid but the lession had undergone exacerbation and remissions. Biopsy was performed on the vesicular lesion and revealed non-acantholytic subepidermal bulla with mild inflammatory cells infiltration and then he was treated with DDS for 2 months with good response.

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.

The incidence of retinopathy of prematurity(ROP) was observed in 194 infants admitted in our nursery room, who had birthweighs less than 2000 gm, or who had gestational ages less than 37 weeks and received supplemental oxygen therapy. To minimize the multiple correlation of birthweights and gestational ages with other possible risk factors of ROP, we selected a control group of normal infants whose birthweights or gestational ages were similar to ROP group, and then other risk factors were analyzed statisticully through a case-control study. Among 194 infants, 41 infants(21%) were diagnosed as ROP. The incidence of ROP was 48%(24/50) in infants with birthweights less than 1500 gm , 41%(28/68) in infants with gestational ages less than 32 weeks(p<0.001). In the case-control study, there were statistically significant differences in the duration of oxygen therapy and the maximal oxygen concentration betweenROP and control group, and long duration(>or=5 days) ahd high concentration(>or=40%) were highly associated with ROP(p<0.01). Other statistically significant risk factors included mechanical ventilation duration, 5 minutes Apgar score, apnea of prematurity, blood transfusion, anemia, asphyxia neonatorum, respiratory distress syndrome, xanthine administration, and parity, cesarean section, pregnancy induced hypertension in mother's factors(p<0.05).

BACKGROUND: Hemorrhage itself has been shown to produce abnormalities in immunity, particularly depression of the lymphocyte function. In order to better examine the amount of hemorrhage required to suppress the lymphocyte function, we determined the effect of graded fixed-volume hemorrhage on splenocyte proliferation and the lymphocyte subpopulation. METHODS: Male Sprague-Dawley rats(weight, 350~400g) were anesthetized, subjected to hemorrhages of 7.5ml/kg, 15ml/kg, and 22.5ml/kg by percutaneous cardiac puncture with 26G needles. After 1, 2, 4, and 7 days, animals were killed to obtain the blood and spleen. The splenocyte proliferative capacity was measured by using the tritiated thymidine incorporation technique, and the peripheral lymphocyte subpopulation was determined using flow cytometry with the following monoclonal antibodies: T cell(CD3+), T helper cell(CD4+), T cytotoxic cell(CD8+), and B cell(CD45RA+). RESULTS: Hemorrhage of 7.5ml/kg did not induce depression of splenocyte proliferation. However, for hemorrhage greater than 15ml/kg, the splenocyte proliferative capacity was significantly depressed at 2 days after hemorrhage and recovered at 4 days. Hemorrhage induced no changes in the relative percentage of lymphocyte subpopulations and in the number of each cell in peripheral blood. CONCLUSION: This study suggests that cellular immunity is depressed at 48 hrs after a hemorrhage greater than 15ml/kg without any change in the peripheral lymphocyte subpopulation.

Gastritis cystica profunda (GCP) is an uncommom hyperplastic lesion, which is located within the submucosa. GCP may occur several years after previous gastric surgery. In some reported cases, it was a premalignant condition and may lead to carcinoma of the stomach. We report a case of a 54-year-old man with epigastric pain and dyspepsia. He had undergone peritoneal dialysis for end stage renal disease about 13 years prior. An Upper gastrointestinal endoscopy showed elevated lesion at the gastric antrum, looking like an advanced gastric cancer or gastrointestinal stromal tumor. Endoscopic biopsy results were tubular adenoma with low-grade dysplasia. When followed up 9 months later, the lesion had increased in size and symptoms remained. We therefore performed a subtotal gastrectomy. The final biopsy was adenocarcinoma arising in GCP.

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.
