Five cases of inflammatory or fibrous lesions of stomach wall which had resulted in a swelling of the wall, and clinically arose a suspicion for malignancy, had been reviewed and analyzed again, and the following conclusions are obtained. 1) Most patients are male(4/5), average age is 30 years. 2) Clinically recognized pyloric stenosis are found in 2 cases out of five. One of the two had a two years' history indicating a mild stenosis. 3) There are 3 cases of eosinophilc granuloma, one case of plasma cell granuloma and one case of fibroid polyp. One of the three eosinophilia(10%) in peripheral blood, and in the gastric lesion there was an Anisakis larva(partial gastrectomy was done five days after the onset of the disease). 4) Length of the clinical history were each 5 days, 3 months, 6 months, 6 months, and 2 years. The latter case had a Fibroid polyp in the antrum. 5) Fibroid polyp showed an ucler and a sessile polyp at the mucosal surface of the lesion. 6) Basic pathologic change is an inflammation, for this reason, majority of this lesion may have an ability for natural healing, esp. if the lesion is small in size. Scar tissue which these lesions may leave behind, will accompany and ucler or polypoid lesions later. Also, they may provide a chance to produce a so-called ucler-cancer or scar-cancer at the vicinity of the scar of the stomach.

Potter's syndrome was originally described as combination of bilateral renal agenesis and unique progeric facial characteristics in 1946 by Potter. In cases of severe renal maldevelopment such as bilateral polycystic kidney or marked hypoplasia, similar facial features has been also associated. At 1963, Potter and Osathanondth reported classification of polycystic kidney as Type I-IV by microdissection study. Recently authors experienced an autopsy case of polycystic kidney with characteristic potter face, and other combined malformations such as; absence of both ureters and urinary bladder, pulmonary hypoplasia, undescended testes and oligohydramnios, fetal growth retardation and breech presentation. According to the classification of polycystic kidney of Potter and Osathanondth, this presenting case is compatible with type IIB.

Epidemiology, pathology, diagnosis and treatment of gastric carcinoma has been revised recently. The authors analysed 3,170 cases of gastric carcinoma which were diagosed with fiberoptic biopsy or resected specimens from 1968 to 1988 in Pusan area. The specimen were collected from Pusan National University Hospital, Pusan Paik Hospital and other general hospitals in Pusan city. The results obtained were summarized as follows; 1) The time trend indicated that difference in the annual fluctuation of requency of gastric carcinoma during last 21 years was not statistically significant. But it was noticed that by comparing the following the two decades (1970~1979 and 1980~1988) the frequency of gastric carcinoma decreased in male, in middle age and in intestinal type. 2) Morbidity of gastric carcinoma increased in both sexes by aging, and this tendency was more marked in male and in intestinal type in female and in diffuse type. 3) In general the gastric carcinoma involved more frequently distal portion than proximal portion of the stomach was characterized predominantly by male, older patients and intestinal type. 4) Carcinoma with Borrmann type I and II were characterized predominantly by male, older patients and intestinal type. With Borrmann type III and IV, female, young patients and diffuse type were found more frequently. From the above results, the authors concluded that the pathological and epidemiological findings of gastric carcinoma among Koreans in Pusan area showed a transition moving from high risk to low risk area of gastric carcinoma.

The growth pattern of 137 cancers of surgically removed stomach specimen were studied in relation to histological type and stromal reaction, namely, the degree of lymphocytic infiltration and fibrosis, and several characteristies were noted. Generally, stromal fibrosis increased more in the expanding type of growth of the cancer while the degree of lymphocytic infiltration did not. As an invasive growth pattern of cancer 5 directly affect on the prognosis of the stomach cancer, a graph was designed which can be used to help to predict the degree to which the cancer may be experted to have a greater tendency to expand locally or invade deeper. However, an increase in the number of metastatic lymph node parallels an increase in the size of the cancer.

Stomach of 34 year old man showed an early stage of the cancer with slight involvement of the superficial part of the inner muscle layer and accompanied with one metastatic lymph node. The cancer is that of medium differentiated adenocarcinoma. There is an heavy infiltration of lymphocytes mixed with histiocytic mononuclear cells and multinucleated giant cells. Some giant cells appear as Langhans' type suggesting phagocytic cells of their origin containing PAS positive materials in the cytoplasma. In other places, they appear as atrophic cancer nests suggesting that these tumor nests were arrested and undergone to regressive cellular process because of the over-whelming immunological pressure by the host.

BACKGROUND: The emergence of metronidazole (MTZ) resistance among Helicobacter pylori (H. pylori) isolates has compromised the efficacy of the triple therapy. Therefore, special attention should be given toward reliable methods for determining the in vitro susceptibility. But susceptibility testing of H. pylori is not yet either standardized or routinely performed. The purpose of this study was to establish more reliable, but simple to perform and cost-effective antimicrobial susceptibility testing method. METHODS: With 135 clinical isolates of H. pylori, antimicrobial susceptibility tests for MTZ and clarithromycin (CLR) were performed by antibiotic gradient method (E test, AB BIODISK, Sweden) and disk diffusion method (disk method), and the results were compared with the reference modified broth microdilution method (broth method). RESULTS: Resistant rates of Korean isolates of H. pylori for MTZ and CLR were 46.2% and 2.2%, respectively. There was 100% agreements between the E test, disk method and the broth method for CLR. For MTZ, however, agreements between the results obtained by the three methods were variable. Between the E test and broth method, the agreements were 85.1% in terms of susceptibility categories, 80.5% between the disk and broth method, and 93.1% between the E test and disk method. CONCLUSIONS: Routine susceptibility testing of H. pylori to MTZ seems to be required in Korea. The broth method is recommended for MTZ until more accurate, simple and practical alternative method become available. For the CLR, the disk method is recommended, because it is reliable, simple, and economical.
