PURPOSE: This study was done to verify effects of a positive psychotherapy program on depression, self-esteem, and hope in patients with major depressive disorders. METHODS: A nonequivalent control group pre-post design was used. Participants were 53 people (control group=27 and experimental group=26) who were diagnosed with a major depressive disorder and received psychiatric outpatient treatment. The data were collected from July 1 to December 30, 2013. The experimental group received the positive psychotherapy program 8 times over 8 weeks. Data analysis was conducted using chi2-test, Fisher's exact test and t-test. RESULTS: As the result of the intervention, depression (p<.001), self-esteem (p<.001) and hope (p<.001) improved significantly in the experimental group compared to the control group. CONCLUSION: The results suggest that the positive psychotherapy program can be widely utilized as one of the nursing intervention programs for depressive patients.

BACKGROUND: Although adult immunization is as important as childhood immunization, is being inadequately performed. However, previous studies concerning adult immunization could not be sufficiently evaluate because studies were restricted to the residents in rural area or those who have visited a doctor. METHOD: We conducted a study by telephone interview which included 201 household(375 adult family members) selected by systematic sampling from the yellow pages of Kangnam-gu and Sungbuk-gu districts of Seoul. The types of immunization covered in this study were immunizations against hepatitis B, influenza, pneumococcus, and hemorrhagic fever with renal syndrome(HFRS). Immunization status of all adult household members, cognition of the feed for immunization and of interviewees were surveyed. Sex, age, area of residency, education medical history of study subjects were considered as factors related to the cognition of the need for immunization and immunization performance. RESULT: The cognition rates of immunization were as follows: hepatitis B 85.1%, influenza 45.8% pneumonra 38.3%, and HFRS 38.3%. In the people over 65 years old, the cognition rate against influenza and pneumococeus were 6.25%, 6.25% respectively and for those she have chronic disease.80.0%, 20.0%, respectively. The cognition rates of immunization was significantly higher among those subject who were young, well educated, and those residing in Kangnam-gu district. The immunization performance rate of hepatitis B was 6.5%, influenza 5.6%, pneumonia 0.8%, and HFRS 1.1%. 75.5% of subjects vaccinated against hepatitis B had received at least three titles. The immunization performance rate of influenza and pneumococcus by the immunization indication are as follows 8.0%, 0.0%, respectively in the subjects over 65 years old, and 11.1%, 0.0,% respectively in the people who have chronic disease. The immunization performance rate of hepatitis B was higher among young, well educated subjects living in Kangnam-gu district. But age, education, area of residency played no apparent role in the case of other types of immunization. The immunization performance rate of those who felt the need for immunization as significant1y higher then that of those who did not. To assess the factors which re]ate to the correct cognition for immunization necessity, we used a multiple logistic regression test. For all types of immunization surveyed, sex(femals) and age (young) seemed to be significantly related to the correct necessity cognition. Medical history of chronic disease was also related to the correct necessity cognition for immunization against hepatitis B and influenza. CONCLUSION: This study reveals that among living in urban area the immunization performance rate and the correct cognition rate concerning the necessity for adult immunization was generally very low. Therefore, an active publicity and pubic education will be needed to increase the level of correct necessity cognition for immunization in which the disease status, sex, and age of vaccinee are considered. And more active effort to increase the cognition for immunization necessity performance is required.

OBJECTIVES: Late-onset schizophrenia (LOS, age at first onset ≥40 years) is characterized by including predominance of women, better premorbid social adjustment and lower severity of positive/negative symptoms. However, few studies have been conducted on LOS, especially in Asian countries. This study aimed to examine the clinical features of LOS in comparison with early-onset schizophrenia (EOS). METHODS: By retrospectively reviewing medical records, we assessed demographic data and clinical features of 76 LOS (20 males) and 357 EOS (144 males) who admitted to the psychiatric ward of a general hospital. RESULTS: The mean ages of onset were 47.3±5.1 (LOS) and 25.7±6.5 (EOS) years. There were significantly more women in LOS (73.7%) than EOS (59.6%). Significantly more LOS patients had a marital (88.2% vs. 25.8%) and employment history (28.9% vs. 13.1%) than EOS. Patients with LOS had fewer negative (14.3±9.0 vs. 19.9±9.3), general psychopathology score (36.9±11.1 vs. 42.3±13.9) than EOS patients. CONCLUSION: In line with previous studies, this study demonstrated that LOS patients have better premorbid social adjustment. Our finding also replicates previous findings that LOS patients differ from EOS in predominance of women and relative lack of negative symptoms. These results suggest that LOS may be a distinct subtype of schizophrenia.

Background: Larger middle molecules are important substances associated with cardiovascular complications in end- stage renal disease. Unfortunately, larger middle molecules are not reliably removed by a high-flux dialyzer. A medium cut-off (MCO) membrane could effectively remove larger middle molecules. This study aimed to identify the long -term effect of the MCO membrane for changes of larger middle molecules. Methods: Thirty-four patients were prospectively analyzed for 12 months. The enrolled patients were divided into control and MCO groups. We measured the plasma levels of growth differentiation factor 15, sclerostin, and fibroblast growth factor 23 in larger middle molecules and those of biomarkers including small solutes. Single-pool Kt/V (spKt/V) and reduction ratios also were evaluated. Results: Plasma sclerostin did not increase significantly in patients using the MCO dialyzer (135.3 [–637.7 to 908.3], p = 0.715). And there was a significant difference in change of plasma sclerostin level between the two groups (–1,646.9 [–3,015.2 to –278.7], p = 0.033). Furthermore, a negative association between calcium and sclerostin was not observed in the MCO group (r = –0.142, p = 0.587). Solute clearance of larger middle molecules in the MCO group was significantly higher. Moreover, spKt/V values for patients in the MCO group were significantly increased without albumin loss. Values are presented as mean (95% confidence interval [CI]) or adjusted mean (95% CI). Conclusion The MCO dialyzer can increase dialytic adequacy and suppress the increase in plasma sclerostin level without significant albumin loss in patients with end-stage renal disease.

PURPOSE: The morphologic characteristics and adhesion complex formation of cultured limbal epithelium of rabbit on amniotic membrane, in vitro and in vivo. METHODS: Rabbit limbal explants were cultured in vitro on amniotic membrane for 4 weeks. In the in vivo culture, the rabbit corneal epithelium was removed. Next, a tunnel was created at the limbus and, the edge of amniotic membrane was secured in the tunnel and cultured for 4 weeks. The proliferation of epithelium on the amniotic membrane was observed for 4 weeks at 1 week intervals. RESULTS: AE-5 immunohistochemical staining was positive and PAS staining was negative for cultured rabbit limbal epithelium, in vitro and in vivo. Hematoxylin and Eosin staining showed the morphologic characteristics of normal rabbit corneal epithelium in both groups. Transmission electron microscopy performed at an interval of 1 week showed adhesion complex by 3 weeks of in vitro culture, and no significant change was seen until week 4. The formation of the adhesion complex was shown starting at week 1 of in vivo culture and increased until week 4. CONCLUSIONS: The morphology of corneal limbal epithelium of rabbits cultured on amniotic membrane in vitro and in vivo, did not differ significantly compared with normal rabbit epithelium. In vivo culture resulted in more a normal-looking adhesion complex compared with the in vitro culture.

BACKGROUND: The yeasts of the genus Malassezia are members of the normal flora on human skin and they are found in 75~80% of healthy adults. Since its association with various skin disorders have been known, there have been a growing number of reports that have implicated Malassezia yeast in atopic dermatitis (AD). OBJECTIVE: The aim of the present study is to isolate the various Malassezia species from AD patients by using 26S rDNA (ribosomal Deoxyribonucleic acid) PCR-RFLP and to investigate the relationship between a positive Malassezia culture and the severity of AD. METHODS: Cultures for Malassezia yeasts were taken from the scalp, cheek, chest, arm and thigh of 60 patients with atopic dermatitis. We used a rapid and accurate molecular biological method 26S rDNA PCR-RFLP, and this method can overcome the limits of the morphological and biochemical methods. RESULTS: Positive Malassezia growth was noted on 51.7% of the patients with atopic dermatitis by 26S rDNA PCR-RFLP analysis. The overall dominant species was M. sympodialis (16.3%). M. restricta was the most common species on the scalp (30.0%) and cheek (16.7%). M. sympodialis (28.3%) was the most common species on the chest. The positive culture rate was the highest for the 11~20 age group (59.0%) and the scalp showed the highest rate at 66.7%. There was no significant relationship between the Malassezia species and SCORing for Atopic Dermatitis (SCORAD). CONCLUSION: The fact that the cultured species was different for the atopic dermatitis lesion skin from that of the normal skin may be due to the disrupted skin barrier function and sensitization of the organism induced by scratching in the AD lesion-skin. But there was no relationship between the Malassezia type and the severity score. The severity score is thought to depend not on the type, but also on the quantity of the yeast.

Blastic natural killer (NK) cell lymphoma is a rare neoplasm characterized by blastoid tumor cells expressing CD4 and CD56, with predominant skin involvement. Although this tumor has been regarded as a neoplasm related to NK cell, recent studies suggested that it is derived from plasmacytoid dendritic cells, but not from NK cell. Herein we report 4 cases of CD4+CD56+ lineage marker- blastic NK cell lymphomas with a review of literatures. The patients were 3 men and one woman. Three of them were young (17, 18, and 22 yr old). Three patients had skin lesions, at initial presentation in two patients and during the course of disease in other patient. Histologically, tumors consisted of monotonous medium to large blastoid cells showing no necrosis, angiocentric growth or epidermotrophism. All four tumors were CD4+ and CD56+. Three expressed CD68 antigen. Lineage specific markers for B- and T cell were negative. All tumors did not express myeloperoxidase. T-cell receptor gene rearrangement, EBV, CD13 and CD33 were negative. In one patient, tumor cells arranged in Homer-Wright type pseudorosette and expressed terminal deoxynucleotidyl transferase(TdT). Despite the standard lymphoma chemotherapy, the tumors, except one lost during follow-up, progressed and relapsed. The patients died 8-60 months after diagnosis.

BACKGROUND: Persistent organic pollutants (POPs) are toxic materials that cannot be broken down naturally and that easily accumulate in the body. Although several studies have attempted to reveal the effects of POPs on the endocrine and nervous system and on cancer, few studies focus on the relationship between low-dose POPs and public health. We attempted to find a relationship between the level of POPs and common gastrointestinal symptoms, including abdominal discomfort, diarrhea, and constipation. METHODS: We recruited 121 subjects who visited Kyungpook National University Hospital for a health screening. Plasma concentrations were evaluated for 40 kinds of POPs including 17 types of polychlorinated biphenyls and 23 types of organochlorine pesticides. Furthermore, the Korean version of the Rome III criteria was used to identify gastrointestinal symptoms. RESULTS: Our results showed that abdominal discomfort had an inverse relationship with several polychlorinated biphenyls. Moreover, an inverted U-shaped relationship was observed between abdominal discomfort and several other organochlorine pesticides including p,p'-dichlorodiphenyldichloroethane and p,p'-dichlorodiphenyltrichloroethane, and the effects of these pesticides on abdominal discomfort were similar to that of organochlorine pesticides on obesity and metabolic syndrome. CONCLUSION: Our results suggest that mild and unspecified gastrointestinal symptoms with no clear cause could be related to POPs levels.

METHODS: We recruited 121 subjects who visited Kyungpook National University Medical Center for health screening. Plasma concentrations were evaluated for 40 kinds of POPs including 17 types of polychlorinated biphenyls (PCBs) and 23 types of organochlorine pesticides (OCP). Furthermore, the Korean version of the Rome III criteria was used to identify gastrointestinal symptoms. RESULTS: Based on our results, abdominal discomfort showed an inverse relationship with several PCBs and an inverted U-shaped relationship with several other OCPs including pp-DDD and pp-DDT. The effects of pp-DDD and pp-DDT on abdominal discomfort were similar to those of OCPs on obesity and metabolic syndrome. CONCLUSION: Our results suggest that mild and unspecified gastrointestinal symptoms with no clear causes could be related to POP levels.
