BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

PURPOSE: The cross-protection of 7-valent pneumococcal conjugate vaccine (PCV7) against vaccine-related serotypes has been controversial. We investigated the serological properties of cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A induced in young children aged 12-23 months after booster immunization of PCV7. METHODS: IgG and IgM antibody concentrations and opsonic index (OI) against vaccine serotypes 6B and 19F and vaccine-related serotypes 6A, 6C, and 19A were measured by ELISA and opsonophagocytic killing assay (OPA) in 4 selected immunesera. The serological properties and antigenic specificity of protective antibodies were determined by IgM depletion of immunesera, OPA, and competitive OPA against serogroup 6 and 19 pneumococci. RESULTS: Compared to pre-IgM depleted immunesera, OI of IgM-depleted immunesera against 6B and 19F decreased and OI against 6A, 6C, and 19A decreased, too. In competition OPA, free 6B and 19F polysaccharide completely inhibited the immune protection against vaccine-related serotypes 6A, 6C, and 19A as well as vaccine types 6B and 19F. CONCLUSIONS: The booster immunization of PCV7 certainly induced cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A with both IgG and IgM isotypes. Furthermore, IgM antibodies are more highly contributed to opsonophagocytic activity against vaccine-related serotypes as well as most of vaccine types than do IgG antibodies. Further studies are needed for the more immunized sera in the children as well as adults.

Solitary fibrous tumors (SFTs) most often involve the pleura and also may encompass the peritoneum and nonserosal sites. They occur as solitary encapsulated tumors and pursue a relatively benign clinical course. The usual criteria for malignancy are high cellularity, mitotic activity (more than 4 per 10 high-power fields), cellular pleomorphism, hemorrhage and necrosis as well as infiltrative growth. We report a case of malignant SFT of pleura who presented with an anterior mediastinal mass. Grossly, it was a 10x8x6.5 cm sized, encapsulated and well-demarcated, solid neoplasm with areas of extensive necrosis. Microscopically, parallel or haphazard arrangement of spindle cells with variable degrees of collagenous background were noted. Storiform fascicle formation, hemangiopericytoma-like pattern, and epithelioid cell clusters were often intermingled. Nodular areas with high cellularity and mitotic activity (> or =10/10 HPFs) were scattered throughout the neoplasm, however no definite cellular pleomorphism was encountered. Tumor cells were immunoreactive for vimentin and CD-34, which distinguished them from the mesothelial cells. Electron microscopically, they revealed fibroblastic and myofibroblastic differentiation.

Intestinal tuberculosis is an infectious disease which is still prevalent in the developing countries including Korea. It may occur insidously, have a vague clinical marofestation, and take a chronic course. We have analyzed 101 cases of intestinal tuberculosis. proven by clinical and histopathologic diagnosis for 10yrs since 1977. The results are as follows: 1) Intestinal tbc was prevalent in the age of 20-30 and the male to female ratio was 1:1.7. 2) Among clinical manifestations, abdominal pain, and tenderness, general malaise and abdominal mass were observed in order of frequency. 3) Active pulmonary lesion was associated in 73 cases (73.3%). 4) Ileocecal region was the most frequent site of involvement in barium study and in colonoscopy. 5) The most frequent colonoscopic finding was multiple ulceration and pseudopolyposis and chronic granulomatous inflammation was noted in 58% on hitopathology. 6) Ulcerative type was the most common type 45.4% by intestinal x-ray and colonofiberscopic examination

BACKGROUND: The multifactorial hypothesis is proposed as a working hypothesis which encompass both the genetic and environmental factors known to participate in the etiology of congenital heart anomalies. So, at the moment, it is believed that avoidance of suspected environmental factors in early pregenancy is most certain preventive measure of congenital heart anomalies. This study has been undertaken in order to find the possible environmental risk factors for congenital heart anomalies in Korea. METHOD: A total of 320 mothers of infants with congenital heart anomalies diagnosed at Seoul National University Hospital were included in this study as case group. And 413 mothers of healthy infants, who visited well baby clinic at the hospital during the same period of 2 years from 1987, comprised the control group. Data related to environmental risk factors including drug use during the first trimester of pregnancy, any other confounders were collected by direct interview using questionmaires. RESULT: There were positive associations for lower educational level of mother, indoor smoking habit of father, number of pregnancy, and of experience of previous abortion of mother, and multiple(or twin) birth. Relative risk estimates for the first trimester exposure to anti-emetics and herb medicine were 2.1(p<0.006) and 1.4(p<0.044), respectively. Data showed a positive association between anti-inflammatory drug exposure and congenital anomalies of pulmonary valve(OR=22.7, p<0.01), and between anti-histamine exposure and coarctation of aorata(OR=12.7, p<0.017). CONCLUSION: Environmental factors such as smoking habit of father, certain drugs used in early pregnancy, plays a role in the etiology of congenital heart anomlaies. Further studies, designed to focus on specific drug and to differentiate the effect of the suspected drug and to differentiate the effect of the suspected drug form that of the underlying conditions prompting its use, should be called upon.
