Immunoglobulin G4 (IgG4)-associated autoimmune hepatitis (AIH) is a very rare subtype of autoimmune hepatitis and characterized by marked elevated serum IgG and hepatic infiltration of IgG4-expressing plasma cells. Pathologic confirmation of hepatic IgG4-expressing plasma cells is usually required for the final diagnosis of IgG4-associated AIH. Herein, we report the case of a 47-year-old female diagnosed with autoantibody-negative IgG4-associated AIH mimicking lymphoproliferative disorders.

We prove a functional central limit theorem for a linear random field generated by negatively associated multi-dimensional random variables. Under finite second moment condition we extend the result in Kim, Ko and Choi[Kim,T.S, Ko,M.H and Choi, Y.K.,2008. The invariance principle for linear multi-parameter stochastic processes generated by associated fields. Statist. Probab. Lett. 78, 3298-3303] to the negatively associated case.

Objectives: In the USA, certain races and ethnicities have a disproportionately higher gastric cancer burden. Selective screening might allow for earlier detection and curative resection. Among a USA-based multiracial and ethnic cohort diagnosed with non-cardia gastric cancer (NCGC), we aimed to identify factors associated with curable stage disease at diagnosis. Methods: We retrospectively identified endoscopically diagnosed and histologically confirmed cases of NCGC at Mount Sinai Hospital in New York City. Demographic, clinical, endoscopic and histologic factors, as well as grade/stage of NCGC at diagnosis were documented. The primary outcome was the frequency of curable-stage NCGC (stage 0-1a) at diagnosis in patients with versus without an endoscopy negative for malignancy prior to their index exam diagnosing NCGC. Additional factors associated with curable-stage disease at diagnosis were determined. Results: A total of 103 racially and ethnically diverse patients were included. Nearly 38% of NCGC were stage 0-Ia, 34% stage Ib-III, and 20.3% stage IV at diagnosis. A significantly higher frequency of NCGC was diagnosed in curable stages among patients who had undergone an endoscopy that was negative for malignancy prior to their index endoscopy that diagnosed NCGC, compared to patients without a negative endoscopy prior to their index exam (69.6% vs. 28.6%, p=0.003). A prior negative endoscopy was associated with 94.0% higher likelihood of diagnosing curable-stage NCGC (p=0.003). No other factors analyzed were associated with curablestage NCGC at diagnosis. Conclusions: Endoscopic screening and surveillance in select high-risk populations might increase diagnoses of curable-stage NCGC. These findings warrant confirmation in larger, prospective studies.

The relation of parents' emotion socialization to emotionality in their 5-year-old children was studied in 106 mothers and 105 fathers. They reported on their own family-related emotional expressiveness and on their children's negative emotions by questionnaires; mothers rated children on both positive and negative emotionality. Results showed that mothers expressed positive and negative emotions more frequently, and mothers showed more distress, expressive encouragement, and problem-focused reactions to children's negative emotions than fathers. Mothers' emotional expressiveness was related to children's emotionality, whereas only fathers' negative emotional expressiveness was related to children's negative emotionality. Mothers' distress and punitive reactions were associated with children's positive and negative emotionality. Mothers' problem-focused and emotion-focused and fathers' problem-focused reactions were associated with children's positive emotionality.

In this paper, the weak laws of large numbers for sums of asymptotically almost negatively associated random vectors in Hilbert spaces are investigated. Some results in Hien and Thanh ([3]) are generalized to asymptotically almost negatively random vectors in Hilbert space.

The purpose of this study is to examine the gender differences in the level of work/family spillover and factors explaining the spillover. Data are gathered from 1,236 Korean men and women aged between 30 to 59, using the structured questionnaire. The main results of this study are as follows. First, both men and women perceive moderate levels of negative and positive spillover from work to family. Second, the levels of negative family to work spillover are higher than then of positive family to work spillover. Third, men report higher levels of positive family to work spillover, but lower levels of negative family to work spillover than women. Sander differences in the levels of negative and positive spillover from work to family are not found. Fourth, only job characteristic factors are associated with four types of spillover of women, while the level of household labor sharing and spousal support are associated with work family spillover of men. Band on these findings, theoretical implications in terms of work-family research and gender norms are discussed.

Group A Streptococcus strain ST4529 is a provisional new ems type which has been recently reported in Malaysia (Jomal, et al. 1999. Energ. Infect . Dis. 5,10-14). This strain was found to be opacity factor (OF) negative with a Tl phenotype. Usually, OF negative strains with T1 phenotypes are associated with acute rheumatic fever. However, strain ST4529 was isolated from the blood of a patient with septicemia. Comparison of the deduced amino acid sequence of the mature hypervariable N-terminus of ST4529 showed only 43% identity with that of M5, the closest matched OF negative strain with a T1 phenotype. Thus, ST4529 most probably encodes a new serospecifically unique M protein which is associated with septicemia rather than pharyngitis infections. The strains with these phenotypes are very important because their sequences should be considered for developing any anti-streptococcal vaccines.

Antagonism between the Youngnam and Honam regions of Korea as expressed by adolescents and their parents was studied in 167 parent-adolescent pairs (total 334) of Youngnam residents. Adolescents were middle school students 71 (42.5%) and high school students 96 (57.5%), 90 boys (53.9%), 77 girls (46.1%). The instruments were subjects' self-reported social distance and stereotypes. Data were analyzed by t-test, paired t-test, Pearson's Correlation, and hierarchical regression. Major findings were that : (1) adolescents' social distance was positively associated with adolescent and parent negative stereotypes. (2) Adolescent positive/negative stereotypes were positively associated with parent positive/negative stereotypes. (3) Adolescent negative stereotypes exerted an indirect effect on social distance, controlled by parents' negative stereotypes.

Subjects of this study were 621 children selected from 5th and 6th grades of elementary schools in Pusan. Factors associated with parents and peers varied by type of peer maladjustment(aggressive type and withdrawn type, compared with a control group). Particularly, the level of factors associated with peers varied from the control group by peer maladjusted types(aggressive types and, withdrawn types). Causal relationships of parents' rejection, victimization, negative representation by parents and by peers on child？s maladjustment varied by behavior types. Negative representation of peers had a direct effect only on withdrawal. On the other hand, negative representation of peers had no effect on aggression. Victimization had a first total effect on both withdrawal and aggression.
