Anisakiasis is a parasitic disease of the gastrointestinal tract caused by ingestion Of raw or undercooked fish containing the marine nematode larvae belong to the subfamily Anisakinae. The adult worms are intestinal parasites of marine mammals. Eggs are passed in the feces of these mammals and develop to the second stage larvae in the sea water. They are eaten by crustaceans in which the larvae develop to the third stage. When fish or squid eat the infected crustaceans the larvae migrate to the body cavity or the muscle. The infected fish or squid is eaten by marine mammals the larvae attach to the wall of the stomach and then undergo adult worm. In Korea, human anisakiasis is not rare. The clinical manifestations are variable and depend on the involving site of gastrointestinal tract. The frequent sites are stomach and small intestine, and large intestine is rarely involved. Recently we experienced two cases of ileal anisakiasis occurred in 54-year-old female and 46-year-old female patients. The symptoms were upper and lower abdominal pain, nausea, and vomiting. The resected ileums in case I and 2 measured 12.5 x 2.5 cm and 15.0 x 2.0 cm, respectively. The mucosa and submucosa were thickened. In case 1, submucosal penetration of a white thread-like parasite was seen. The ileum showed submucosal edema, and extensive infiltration of eosinophils, neutrophils, lymphocytes, histiocytes, and plasma cells from mucosa to mesentery with or without mucosal ulceration. The Anisakis larvae are found in the submucosa and propria muscle. They have thick multilayered smooth cuticle, many somatic muscle cells, triradiated esophagus with numerous tall columnar cells, renette cell, and Y-shaped lateral chords. Reproductive organ is absent. In Korea, the previously reported 14 cases and present 2 cases of the intestinal anisakiasis mainly involved ileum, but the cause was not mentioned.

The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC (80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported data were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers (SNOMED code micro glossary), and certain disease entities on very short duration.

Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis. Their radiologic appearance is relatively distinct and well defined. Recently we experienced 3 cases of sclerosing hemangioma of the lung in 54, 52, 51 years old women. The light microscopic findings are similar to the features reported by Liebow and Hubbell (1956).

Lymphomatoid papulosis is an enigmatic disease entity which is clinically benign and histologically malignant. Although sporadic cases have been reported, we could not find any comprehensive report on the combined clinical and histologic features of lymphomatoid papulosis in the literature. Perhaps the most controversial aspect of lymphomatoid papulosis is its pathogenesis and categorization as a benign versus a malignant entity. To date, there are no reports on p53 and bcl-2 protein expression in lymphomatoid papulosis. We analysed the clinico-pathological findings of 18 cases with lymphomatoid papulosis during the 10 year period from 1984 to 1995 and examined the prevalence of immunoreactivity for CD30(DAKO, Ber-H2), p53(DAKO, DO-7), and bcl-2(DAKO, 124) using an immunohistochemical(ABC) method. The results obtained are summarized as follows. 1) Age distribution ranged from 20 to 65, with a mean age of 45 years and a sex distribution which showed a male predominence(8:1). The lesions were located on the trunk and extremities(8cases), extremities (7cases), and trunk(3 cases). The morphology of the lesions were papules or plaques(12 cases), and nodules(6 cases). 2) Histopathologic types were classified into 3 types: type A(4 cases), type B(8 cases) and mixed type (6 cases). 3) Positive immunoreactivity for CD30 was seen in 17%(3 of 18cases): type A(2 of 3) and mixed type(1 of 3). 4) The positive immunoreactivity for p53 and bcl-2 was observed in 29%(5 of 18) and 11%(2 of 18), respectively. 5) Cases showing positive immunoreactivity for P53 were type A(1 of 5), type B(1 of 5), and mixed type(3 of 5). 6) Cases showing positive immunoreactivity for bcl-2 were mixed type(2 of 2). One case developed into Ki-1 lymphoma. These results support the idea that lymphomatoid papulosis and Ki-1 lymphoma represent a continuum. The role of p53 gene mutation and bcl-2 activation in the development of lymphomatoid papulosis is currently unknown. But, our results suggest that p53 gene mutation and bcl-2 activation are not a critical step in the development of lymphomatoid papulosis. Further studies are needed to elucidate the role of p53 gene mutation and bcl-2 activation in the development and progression of lymphomatoid papulosis.

This study was conducted to evaluate the expression of p53 and c-erbB-2 using immuno-histochemical methods in 145 primary breast carcinomas and to correlate it with other histo-pathological prognostic factors. Invasive ductal carcinoma represented 129 of the cases. Expression of p53 protein and c-erbB-2 oncoprotein was present in 48% (62/129) and 30% (39/129) of invasive ductal carcinomas, respectively. The expression of p53 protein was stongly associated with a high score of degree of differentiation (p<0.05), nuclear pleomorphism (p<0.05), mitotic index (p<0.05), SBR grade (p<0.05) and MSBR grade (p<0.05), but it was not associated with patient's age, size of tumor or axillary node metastasis. The overexpression of c-erbB-2 C-erbB-2 oncoprotein was strongly associated with a high score of nuclear pleomorphism and a high SBR grade (p<0.05), but not associated with patient's age, size of tumor, axillary node metastasis, degree of differentiation, mitotic index or MSBR grade. An inverse relationship between the expression of p53 protein and estrogen receptor status was found, but the expression of c-erbB-2 was not associated with estrogen receptor status. It is concluded that p53 protein and c-erbB-2 oncoprotein are important prognostic factors in breast cancers, and that the aberrant expression of p53 protein is the most useful prognostic factor becausd of strong association of known histopathological prognostic factors and negative estrogen receptor status.

PURPOSE: Suprapubic vibrating stimulus may improve the urinary symptom in patients with neurogenic bladder. We attempted to evaluate the suprapubic vibration effect on urodynamic study in patient with voiding dysfunction. MATERIALS AND METHODS: From October 1997 to July 1998, We have performed urodynamic studies(UDS) on 30 patients(13 males, 17 females). They had intact suprapubic sensation without lower urinary tract obstruction, who visited under the chief complaints of voiding dysfunction(frequency, voiding difficulty etc.). All patients were checked UDS before and after using a vibrating device(frequency 120Hz, mechanical output 0.081mm), which was placed on the 2?3cm above the pubic symphysis. Results of detrusor pressure were compared pre- and post-vibration at 150ml bladder filling and at strong desire to void and maximum bladder capacity. The most common underlying disease was peripheral lesions(11 cases). Results of UDS were grouped into three. Group I consisted of 11 patients with hyperactive bladder. Group II consisted of 6 patients with normal bladder, and group III consisted of 13 patients with hypoactive bladder. RESULTS: Changes of detrusor pressure at the 150ml bladder filling in group I couldn`t be measured due to early urine leakage. In group II&III, the average detrusor pressure changes of pre- and post-vibration were from 4.2+/-.6cmH2O to 3.8+/-.2cmH2O(p>0.05) and from 5.7+/-.8cmH2O to 6.7+/-.2cmH2O(p>0.05) respectively. Detrusor pressure at strong desire to void was changed from 39.0+/-8.6cmH2O to 40.0+/-0.0cmH2O in group I(p>0.05), 25.3+/-2.8cmH2O to 19.0+/-2.2cmH2O in group II(p>0.05), and from 15.0+/-.9cmH2O to 19.5+/-2.3cmH2O in group III(p<0.05). Changes of maximum bladder capacity were from 222.7+/-8.4ml to 187.5+/-1.7ml in group I(p>0.05), from the 402.0+/-2.8ml to 399.3+/-4.5ml in group II(p>0.05), and from 547.5+/-9.5ml to 520.1+/-9.6ml in group III(p<0.05). In group III, ten of the 13 patients(77%) showed the increase of detrusor pressure at strong desire to void(mean: 6.6cmH2O) and nine of the 13 patients(69%) showed the decrease in maximum bladder capacity(mean: 46.4ml)(p<0.05). CONCLUSIONS: These results suggest that the use of suprapubic vibrator may be an ancillary therapeutic tool in selected patients of voiding dysfunction with hypoactive bladder.

A total of 53 gastric adenomas from endoscopically biopsied gastric mucosa were examined histopathologically. The average age at the time of endoscopic biopsy was 59 years, and gastric adenomas were found to be more frequent in the aged, particularly above the age of 50. The majority of adenomas occurred at the antrum. Concerning the shape of the adenomas, Yamada type II was more frequent (55%). All adenomas were accompanied by varying degree of intestinal metaplasia, and this findings suggest that gastric adenoma develops from intestinal metaplasia. In adenomas with severe atypia (grade III), endocrine cells (argyrophil and argentaffin cells) were markedly decreased or absent. Gastric adenocarcinomas coexistent with adenoma were seen in 5 (9.4%) out of 53 cases, and were more frequent in male than female patients (sex ratio, 4:1) and the average age was 61.4 years. It is suggested that there is a necessity of thorough follow-up study for definitive correlation between gastric adenoma and adenocarcinoma.

OBJECTIVE: To determine the effect of lowering the cutoff values of 3-hour oral glucose tolerance test (OGTT) for gestational diabetes mellitus (GDM). METHODS: Patients with an abnormal 50 gm glucose challenge test (GCT) of more than 130 mg/dL at 24-28 weeks of gestation underwent a 3-hour OGTT at 28-32 weeks of gestation. Patients were divided into four groups according to the criteria recommended by Carpenter-Coustan or National Diabetes Data Group (NDDG) (Control: 50 gm GCT negative [n=268], Borderline: 2 or more abnormal values met or exceeded Carpenter-Coustan criteria but not the NDDG criteria [n=100], NDDG I: 2 or more abnormal values met or exceeded NDDG criteria, [treated, n=70], NDDG II: [not treated, n=42]). Obstetric and perinatal outcomes were analyzed retrospectively. RESULTS: Of 5,827 pregnant women screened for GDM, 112 (1.9%) met the NDDG criteria, whereas 212 (3.6%) met the Carpenter-Coustan criteria. The incidences of poor maternal outcomes were 20.1%, 28.0%, 47.1%, 21.4%, and the incidences of poor neonatal outcomes were 3.7%, 6.0%, 14.3%, 16.7% in the four groups (p<0.05). Multivariable logistic regression analysis showed that 1) NDDG I showed an independent risk factor for poor maternal outcome (OR, 3.37), but the borderline group did not, 2) NDDG I showed an independent risk factor for poor neonatal outcome (OR, 3.87), but the borderline group did not, 3) the borderline group showed an independent risk factor for preterm delivery (OR, 2.67). CONCLUSION: Lowering the cutoff values would increase the number of pregnant women with GDM, while only minimally affecting the perinatal outcomes. Further large-scale prospective studies for Korean pregnant women may be needed.

This study was carried out to evaluate the aberrant expression of p53 protein using immunobistochemical method in 54 surgically resected liver cell carcinomas and to correlate it with clinical and pathological findings. Twenty five out of 54 cases(46%) showed positive reaction in the nucleus of liver cell carcinoma and negative reaction in associated 30 cases of cirrhosis, one case of adenoma and two cases of adenomatous hyperplasia. The p53 protein expression was associated with alpha-FP level(p<0.05), but not associated with HBsAg positivity. It was significantly associated with WHO classification, Edmondson-Steiner grade and nuclear grade p53(p<0.05), but not associated with tumor size, capsule formation, portal vein invasion, cirrhosis in surrounding tissue, Eggel classification, special cell type and mitosis. In conclusion, our results suggest that the aberrant expression of p53 protein can be an advisory factor, at least, for prognosis evaluation.
