  • This study aims to examine the background to the rise of Rei Kawakubo, a Japanese designer who achieved fame by suggesting the concept of deconstruction and recombination of clothes, and to look at environment of the time, the formative characteristics of her design and the Japanese aesthetic sense inherent in her design. As the method of research, collections that Kawakubo unveiled over the past 10 years starting in 2004 were examined, and a survey of the literature was conducted to describe the background of her growth and the Japanese aesthetic sense inherent in the design. According to the study, Kawakubo grew up in the ruins of a war, and went through a time of great tumult, when Western culture was mixing with Japan's traditional culture. She taught herself a method of creation involving the deconstruction of clothes, and their recombination. For this reason, her design from the beginning was inevitably focused on deconstructing clothes before they could be recombined. Through analyses of her collections, it was found that the formative characteristics of her design were characterized by asymmetry, incompleteness, humor and hybridity. Kawakubo created clothes under the influence of an ethnicity that was shrouded in individuality and a traditional aesthetic sense, and the formative characteristics of her design defined by asymmetry, incompleteness, humor and hybridity were closely related to the hybridity represented by Wabi (わび), Yugen (幽玄), Okashi (をかし) and Zakyo (雜居).

  • Background: Helicobacter pylori (H. pylori) is one of the risk factors for gastric cancer (GC). Any prognostic effect of HER-2 status in gastric lymph node metastasis in H. pylori positive cases is unknown. Materials and Methods: A total of 74 patients, 47 (64%) male, and 27 (34%) female, who had subtotal or total gastrectomy and also positive lymph nodes, were included in the study. Age range was 29-87 years, and median age was 58 years. HER-2 expression was assessed in both gastric resection samples and lymph node material with carcinoma metastasis of the same patient by immunohistochemistry (IHC) and silver in situ hybridization (SISH) methods. H. pylori status was examined in gastric materials of all patients. Relationships between HER-2 status in gastric cancers and lymph nodes and H. pylori status were investigated. Results: H. pylori was positive in 40 cases (54%), and negative in 34 (46%). While in the primary tissues of H. pylori positive cases, SISH positivity for HER-2 was observed in 13 cases (86%), SISH negativity was observed in 2 (14%), in metastatic lymph nodes 21 cases (72%) were SISH positive and 8 cases (28%) were SISH negative (P=0.005 and P=0.019, respectively). Initial CEA values were high in 18 cases (78%) with positive H. pylori and in 5 cases (22%) with negative H. pylori (P=0.009). While SISH data of patients were negative in 59 cases (80%) and positive in 15 cases (20%) in primary tissues, they were negative in 56 cases (75%) and positive in 18 cases (25%) in lymph nodes. Discrepancy between primary tissue and lymph node results was detected in 3 cases, in which SISH was negative in the primary tissue and HER-2 expression was positive in the lymph nodes. Conclusions: Clinical progression was poor in H. pylori positive cases with HER-2 negativity in primary gastric tissue, but HER-2 positivity in the lymph nodes. SISH positivity can be expected in H. pylori positive cases, and it may be predicted that these cases can benefit from trastuzumab treatment.

  • Background: To evaluate the location of tumor relapse and imaging modality for detection according to the breast cancer subtype: luminal A, luminal B, HER2 positive luminal B, nonluminal HER2 positive, and triple negative. Materials and Methods: A total of 1244 patients with breast cancer with known estrogen receptor (ER), progesterone receptor (PR), Ki-67 and human epidermal growth factor receptor 2 (HER2), who underwent breast surgery from 2009 to 2012 were analyzed. Patients were classified into the following categories: luminal A (n=458), luminal B (n=241), HER2 positive luminal B (n=227), nonluminal HER2 positive (n=145) and triple negative (n=173). A total of 105 cases of relapse were detected in 102 patients: locoregional recurrence (n=46), recurrence in the contralateral breast (n=28) and distant metastasis (n=31). Comparison of proportions was used to determine the difference between subtypes. Results: Relapse rates by subtypes are as follows: luminal A 23 of 458 (5.02%), luminal B 19 of 241(7.88%), HER2 positive luminal B 15 of 227 (6.61%), nonluminal HER2 postive 19 of 145 (13.10%) and triple negative 29 of 173(16.76%). Luminal A tumors had the lowest rate of recurrence and had significantly lower recurrence rate in comparison with nonluminal HER2 postive (p=0.0017) and triple negative subtypes (p<0.0001). Compared with all other subtypes except nonluminal HER2 positive, triple negative tumors had the highest rate of tumor recurrence (p<0.01). Triple negatives were most likely to develop contralateral recurrence against all subtypes (p<0.05). Detection rate of locoregional and contralateral tumor recurrence were 28.3% on mammography (n=17/60). Conclusions: Luminal A tumors are associated with a low risk of recurrence while triple negative lesions have a high risk. In case of triple negative tumors, the contralateral breast has much more recurrence as compared with all other subtype. In terms of detection rates, breast USG was the best modality for detecting tumor recurrence, compared with other modalities (p<0.05). Subtyping of breast tumors using a molecular gene expression panel can identify patients who have increased risk of recurrence and allow prediction of locations of tumor recurrence for each subtype.

  • To generate a biobetter that has improved therapeutic activity, we constructed scFv libraries via random mutagenesis of several residues of CDR-H3 and -L3 of hu4D5. The scFv clones were isolated from the phage display libraries by stringent panning, and their antiproliferative activity against HER2-positive cancer cells was evaluated as a primary selection criterion. Consequently, we selected AH06 as a biobetter antibody that had a 7.2-fold increase in anti-proliferative activity ($IC_{50}$: 0.81 nM) against the gastric cancer cell line NCI-N87 and a 7.4-fold increase in binding affinity ($K_D$: 60 pM) to HER2 compared to hu4D5. The binding energy calculation and molecular modeling suggest that the substitution of residues of CDR-H3 to W98, F100c, A101 and L102 could stabilize binding of the antibody to HER2 and there could be direct hydrophobic interactions between the aromatic ring of W98 and the aliphatic group of I613 within HER2 domain IV as well as the heavy and light chain hydrophobic interactions by residues F100c, A101 and L102 of CDR-H3. Therefore, we speculate that two such interactions were exerted by the residues W98 and F100c. A101 and L102 may have a synergistic effect on the increase in the binding affinity to HER2. AH06 specifically binds to domain IV of HER2, and it decreased the phosphorylation level of HER2 and AKT. Above all, it highly increased the overall level of p27 compared to hu4D5 in the gastric cancer cell line NCIN82, suggesting that AH06 could potentially be a more efficient therapeutic agent than hu4D5.

  • Background: This study was performed to evaluate the amplification of HER-2/neu in patients with melanoma. Materials and Methods: Amplification of HER-2/neu was evaluated in a group of patients with melanoma, referred to two referral centers in Tehran, using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) techniques. Results: Forty patients with mean age $57.9{\pm}19.5years$ were enrolled in this study. The most frequent type of melanoma was acral, while lower limbs were the most frequent sites. The amplification of HER2/neu was negative in 97.5% of patients with IHC and in 100% of patients with CISH technique. Only one case (2.5%) shows weak positive staining (+2) in IHC method. Fifty five percent of melanoma was ulcerative, and the most common stages of tumors were stages 4b and 3b. More than 47% of cases were in Clark level III, while the mean of Breslow thickness was $3.56{\pm}2.87mm$. The stage of the case that showed weakly positive staining (2+) in IHC was 4b. Conclusions: The amplification of HER2/neu biomarker was negative in patients with melanoma, using both CISH and IHC techniques.

  • Purpose: This study evaluates the association of estrogen receptor(ER), progesterone receptor(PR), Her-2, COX-2, and survivin with the clinicopathological features and outcomes in young Korean women with breast cancer using recently developed tissue microarray(TMA) technology. Materials and Methods: A cohort of 212 young patients with breast cancer diagnosed at the age of 45 years or younger from March 1994 to August 2005, were enrolled in this study. The age range of patients was $23{\sim}45$ years(median age, 39 years). The minimum and median follow-up periods were 24 months and 60 months, respectively. Serial sections of primary tumors were processed by the use of a TMA for immunohistochemical staining for five biomarkers. The correlation of these five biomarkers and the clinicopathological features and outcomes were analyzed by statistical methods. Results: The majority of the patients were stage T1(90 patients) or T2(101 patients), and 105 patients(49.5%) had an axillary node metastasis. The 5-year overall and relapse free survival rates for all of the patients were 90.4% and 82.3%, respectively, and 36 patients had a locoregional or distant metastasis as a first event. Positive expression of ER, PR, Her-2, COX-2, and survivin was determined in 38.2%, 45.3%, 25.9%, 41.5%, and 43.4%, of the tumor samples, respectively. Tumor stage, nodal status, age, as well as expression of ER, PR, and HER-2 status were significantly associated with the disease free survival rate. Tumor stage, nodal status, as well as expression of ER, PR, and HER-2 were significantly related with the overall survival rate. Expression of COX-2 and survivin were not single independent prognostic factors for the disease free and overall survival rate although co-expression of HER-2 and COX-2 had a tendency as a poor prognostic factor. By multivariate analysis, only T stage and lymph node status were significant prognostic factors, and ER status was a marginally significant prognostic factor(p=0.075). Conclusion: Expression of ER, PR and HER-2 were significant prognostic factors for the relapse free and overall survival rate. Expression of COX-2 and survivin were not prognostic factors for young women with breast cancer.

  • Objective: The optimal duration of adjuvant trastuzumab treatment in patients with HER2-positive breast cancer is not known. The aim of this study was to evaluate the efficacy of 6 months of adjuvant trastuzumab treatment in patients with stage II or III HER2-positive breast cancer. Methods: The records of patients with HER2-positive stage II or III breast cancer who were admitted to the Breast Center of Taipei Medical University Hospital and Yuan's General Hospital between 2000 and 2008 were reviewed. All patients received adjuvant trastuzumab at an initial dose of 4 mg/kg followed by a maintenance dose of 2 mg/kg/week for 22 weeks in combination with chemotherapy. Results: A total of 51 patients were included with a mean age of 46.9 years. Approximately 55% of the patients had stage III disease. The mean follow-up time from initiation of treatment was 45.2 months (range, 0.9 to 85 months). During follow-up, 46 patients (90.2%) did not experience tumor recurrence. The mean estimated disease free survival was 80.2 months. The estimated 1-, 2-, 5-, and 7-year survival rates were 97.9%, 93.1%, 93.1%, and 93.1%, respectively. The most common adverse effects were gastrointestinal symptoms (21.6%), chills (17.6%), dizziness (9.8%), and bone pain (7.8%). No cardiac or hematologic adverse events occurred. Conclusion: Adjuvant therapy with trastuzumab for 6 months resulted in a clinical benefit in patients with HER2-positive breast cancer.

  • This study explored a sandplay therapy case of a woman maturing through conflicts with an adolescent son. The goal of the therapy was to relieve her from conflicts with going through individuation process under a free and protected space in sandplay therapy. Forty-six therapy sessions were held. The client exhibited that she needed a conversation with her feminity and maternity in the initial phase of therapy (1-5, regression). In the intermediate phase of therapy (6-43, struggle), she displayed the scenes of meeting of opposites, shadow, death, nurturing and integration of opposites. In the final phase of therapy (44-46, transformation), she showed the acception of her life with leaving her situations to God. Through sandplay therapy in the free and protected space, this study showed the effectiveness of sandplay therapy since the client achieved individuation by showing the acceptance of her life and could control her enraged feelings.

  • Hyponatremia, the most common electrolyte disorder, has been rarely reported as causing rhabdomyolysis. Osmotic demyelination syndrome (ODS), a demyelinating disease of the central pons and/or other areas of the brain, is infrequently reported as associated with rapid correction of hyponatremia. This paper reports a case of ODS after correction of severe hyponatremia complicated by rhabdomyolysis. A 47-year-old female with a history of chronic alcoholism presented herself at the hospital with altered consciousness after three days of nausea and vomiting. She was on a thiazide diuretic for essential hypertension. Her blood tests upon her hospital admission showed hyponatremia ($Na^+$ 98 mEq/L), hypokalemia ($K^+$ 3.0 mEq/L), and elevation of her serum creatine phosphokinase (3,370 IU/L) with an increase in her serum myoglobin level 11,267 ng/mL). She was treated with intravenous fluid therapy that included isotonic and hypertonic salines along with potassium chloride. She became more alert, and her neurological condition gradually improved after the first five days of her therapy. On the ninth day after her admission, she developed progressive quadiaresis associated with dysarthria, dysphagia, and dystonia despite the resolution of her hyponatremia. Magnetic resonance imaging of her brain on 16th day revealed symmetrical areas of signal hyperintensity in her central pons, basal ganglia, and precentral gyrus in T2-weighted images, which are consistent with ODS. Her neurological symptoms steadily improved after six weeks with only supportive treatment and rehabilitation.
