OBJECTIVES: The aim of this study was to investigate Korean Wechsler Intelligence profiles and specific abilities related to attention problem of children with attention-deficit hyperactivity disorder (ADHD). METHODS: The Korean Wechsler Intelligence Scale for Children-fourth edition (K-WISC-IV) and Advanced Test of Attention (ATA) were administered to 91 children and adolescents (age 8.5+/-2.6 years, 73 boys) with ADHD. Pearson correlation and independent t-tests were used. RESULTS: The means of Working Memory Index (WMI) and Processing Speed Index (PSI) showed a score of low average in K-WISC-IV. WMI scores for the K-WISC-IV showed clinically significant correlations with omission errors, commission errors, and response time variability on auditory ATA. PSI scores also showed significant correlations with response time and variability on visual ATA. In addition, significantly lower digit span backward scores were observed in hyperactive-impulsive/combined subtypes compared to inattentive subtype (t=3.60, p<.001). CONCLUSION: Children with ADHD showed significantly lower scores in WMI and PSI which were clinically correlated with ATA scores, and hyperactive-impulsive/combined subtypes showed poorer working memory functions in WMI. Follow-up studies are proposed.

An excess of amyloid beta (Aβ) led to a rise in ROS production, which in turn caused inflammatory reactions and mitochondrial dysfunction, both of which accelerate the progression of Alzheimer’s disease (AD).Natural flavonoids are proposed as possible agents for neurodegeneration. Pectolinarin is an important flavone mainly found in Cirsium species. In this study, we explored the potential neuroprotective effect of pectolinarin in Aβ25-35 -induced SH-SY5Y cells. The result demonstrated that pectolinarin enhanced cell viability. Pectolinarin treatment inhibited Aβ25-35 -induced ROS generation. Pectolinarin also suppressed NO generation by inhibiting the translocation of NF-ĸB and downregulating protein expression of iNOS and COX-2. Moreover, the expression of Bcl-2 increased while BAX protein decreased when the cells were exposed to pectolinarin, resulting in a decrease in the BAX/Bcl-2 ratio. Pectolinarin treatment also increased BDNF and its receptor TrkB protein expression. In conclusion, pectolinarin neuroprotected Aβ25-35 -induced inflammation and apoptosis. These findings suggest that pectolinarin may be a promising neuroprotective functional food in the protection of the neurodegenerative diseases, including AD.

PURPOSE: The aims of this study are to evaluate psychological impact and quality of life according to the cancer diagnosis and mutation status in Korean families with BRCA mutations. MATERIALS AND METHODS: Seventeen affected carriers (AC), 16 unaffected carriers (UC) and 13 healthy non carriers (NC) from 13 BRCA mutation families were included in the study. Outcomes were compared with regard to depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory, STAI), optimism (Reevaluation of the Life Orientation test, LOT-R), knowledge of hereditary ovarian cancer, and quality of life (QoL) (SF-36v2 Health Survey, physical component score [PCS], mental component score [MCS]) among three groups. RESULT: Level of depression, optimism, and PCS were similar in AC, UC, and NC. Anxiety score was elevated in all three groups. MCS was significantly low in AC than in UC and NC (P =0.009, P =0.017). Knowledge of hereditary breast and ovarian cancer was high in AC than NC (P =0.001). MCS was significantly related to whether patient was affected by cancer (P =0.043) and has occupation (P = 0.008) or not in multivariable analysis. CONCLUSION: From this cross sectional study, psychological adverse effect was not related to the carrier status of BRCA mutation. Elevated anxiety in BRCA family members was observed but, independent to affection and the type of genetic mutation. AC showed low mental QoL. Further effort to understand psychological impact and QoL of genetic testing in BRCA family members is required for follow-up in clinical aspects.

PURPOSE: This study aimed to evaluate the survival benefit of different adjuvant chemotherapy regimens in patients with T1-2N0 triple-negative breast cancer. METHODS: Of 67,321 patients who were registered in the Korean Breast Cancer Society nationwide database between January 1999 and December 2008, 4,033 patients with T1-2N0 triple-negative breast cancer were included. The overall survival of patients who did not receive adjuvant chemotherapy was compared with those treated with adjuvant anthracycline and cyclophosphamide (AC), 5-fluorouracil, anthracycline, and cyclophosphamide (FAC), or cyclophosphamide, methotrexate, and 5-fluorouracil (CMF). RESULTS: The median follow-up was 52.5 months. Chemotherapy was used in 87.4% of patients; it was used more commonly in patients with T2 tumors, those who were younger, had a higher histologic grade, and who showed lymphovascular invasion. The 5-year cumulative overall survival rate was 95.4%. Younger age, breast-conserving surgery, and adjuvant chemotherapy were significantly associated with improved overall survival. The 5-year cumulative overall survival rate of patients who did not receive adjuvant chemotherapy and those treated with AC, FAC, and CMF were 92.5%, 95.9%, 95.3%, and 95.9%, respectively. On multivariate analysis, the administration of any adjuvant chemotherapy regimen was significantly associated with improved overall survival (p=0.038). No significant difference in survival benefit was observed among the three different treatment groups. CONCLUSION: A standard adjuvant chemotherapy regimen with the least drug-related toxicity might be a reasonable treatment for patients with T1-2N0 triple-negative breast cancer.

Clear cell tumor of borderline malignancy has been reported to account for 5 to 8% of all clear cell neoplasms, and <1% of borderline malignancies of the ovary. Borderline clear cell fibroadenoma with or without microinvasion mostly occurs in women with middle age, and the presenting symptoms associated with this tumor are non-specific. The clinico-pathologic features of borderline clear cell fibroadenoma are not well known because of its rarity. Furthermore, there is no consensus for treating the disease. Thus, we report a case of borderline clear cell fibroadenoma presenting as ovarian fibroadenoma with a review of literature.
