Epidermal growth factor receptor (EGFR) is an intergral membrane protein. Overexpression or mutation of EGFR may play a role in careinogenesis. Recently, many molecular biologic techniques have been used to study expression of oncogenes. One of them, in situ mRNA hybridization, using paraffin embedded blocks, offers a unique means to allow precise localization within histological preparations, and also overcomes problems relating to translation defects and abnormal translation. In order to confirm the usefulness of epidermal growth factor receptor as a tumor marker, and to compare the expression of EGFR between in situ MRNA hybridization and an immunohistochemical study, in situ MRNA hybridization was performed along with an immunohistochemical study for EGFR in paraffin sections of 84 uterine cervix carcinomas. A positive reaction for EGFR was observed mairdy in the cytoplasm of tumor cells. The vascular muscle layer and uterine muscle tissue around the cancer nest revealed a positive reaction in immunohistochemical stain for EGFR, with a negative reaction for EGFR mRNA. In the cancer nests, the immunohistochemical positive reaction for EGFR was strong in differentiated cells and keratin pearls, but a strong positive reaction for EGFR mRNA was localized in undifferentiated cells. The overall positive of immunostaing for EGFR was 77% for uterine cervix carcinoma; 71 % for carcinoma in situ, 71 % for microinvaseve carcinoma, and 89% for invasive carcinoma. The overall positivity of EGFR from in situ MRNA hybridization was 94% of the uterine cervix carcinoma; 93% for carcinoma in situ, 93% for microinvasive carcinoma, and 96% for invasive carcinoma. From these results, EGFR is a useful tumor marker for uterine cervix carcinoma, and in situ mRNA hybridization has greater sensitivity and specificity than immunohistochemistry.

2.Development and Evaluation of a School Adjustment Model for Juvenile Delinquents.
Journal of the Korean Society of Maternal and Child Health 2017;21(3):182-192
PURPOSE: The aim of this study was to develop and evaluate a structural model including relevant factors to identity the variables that affect school adjustment in juvenile delinquents. On the basis of a review of the literature on school adjustment of juvenile delinquents and on Bronfenbrenner's bio-ecological model, a hypothetical model was developed by setting home environmental factors (e.g.,economic conditions, parent child communication, parenting attitudes, peer relationships, and academic stress) as exogenous variables, and personal factors (e.g., ego identity and psychological well-being) as endogenous variables. METHODS: Data were collected from January 29 to March 3, 2015 by a survey of 206 students attending junior high and high schools in City B. The collected data were analyzed using the SPSS and Amos 22.0 software. RESULTS: The verification of the hypothetical model indicated a good fit for the model: χ²=0.009 df=13, χ²/df=2.161, GFI=0.97, AGFI=0.90, RMESA=0.07, CFI=0.98, TLI=0.95, and RMR=0.01. CONCLUSION: The results suggest that ego identity and parent-child communication do not directly affect school adjustment of juvenile delinquents but influence it depending on the psychological well-being of delinquents. High levels of psychological well-being, better economic conditions, better parent-child communication, and low academic stress were abserved to contribute to better school life. Therefore, to improve the school adjustment of juvenile delinquents, appropriate measures need to be taken and programs need to be designed for improving ego identity and parent-child communication, thus promoting psychological well-being.

Fibrohistiocytic tumors are a diverse group of benign and malignant soft tissue lesions, including dermatofibroma, dermatofibrosarcomaprotuberans, and malignant fibrous histiocytoma. On the clinical point of view, the distinction between benign and malignant lesions and malignancy grading is far more important. Therefore, we investigated 23 fibrohistiocytic tumors, using PCNA (PC10) which was a useful marker of proliferating activity, to differentiate the benign lesions from the malignant and correlate with other prognostic factors including tumor necrosis. cellularity, histologic grade, and mitotic counts. The results obtained were as follows 1) Positive tumor cells were clearly identified by the characteristic diffuse or granular nuclear staining. 2) The number of PCNA-positive tumor cells were 2.16+/-2.39% in dermatofibroma, 16.12+/-7.38% in dermatofibrosacoma protuberans, and 28.02+/-17.47% in the malignant fibrous histiocytoma. The numbers of PCNA-positive tumor cells in the malignant lesions higher than in the benign (p<0.001). 3) Deep seated, large size (>5 cm) and recurred or metastatic cases of MFH were more the high PCNA index (more than 20%) than the low index (less than 20%) groups. 4) PCNA index in MFHs had positive correlation with the number of mitotic counts (r=0.7582, p<0.001), cellularity (r=0.5908, p<0.05) and histologic grade (r=0.4164, p<0.05). These results suggested that reactivity on PCNA might assist in the distinction between benign and malignant lesions in fibrohistiocytic tumors, and could be a useful prognostic factor in the patients with malignant fibrous histiocytoma.

PURPOSE: This study was designed to investigate the difference of oral mucositis in hospitalized cancer patients receiving chemotherapy according to characteristics. METHODS: Data were collected from March 1 to April 25 2012 using questionnaires, and the participants were 177. The Oral Assessment Guide (OAG) by observation and The Oral Mucositis Daily Questionnaire (OMDQ) by self-report were used to measure oral mucositis. The data were analyzed using SPSS 18.0. RESULTS: Moderate to severe oral mucositis measured by OAG observation were 94.9% in hospitalized cancer patients receiving chemotherapy, frequently complaints of mouth and throat soreness measured by OMDQ was 42.4%, and intensity of mouth and throat soreness measured by OMDQ was 0.65 out of 10. There were statistically significant differences in the prevalence of oral mucositis according to nutrition state, frequency of chemotherapy, experience of oral examination, combination treatment, and number of chemotherapeutic agents. CONCLUSION: Many hospitalized cancer patients receiving chemotherapy experienced oral mucositis. Cancer patients receiving chemotherapy with poor nutritional status, more frequent chemotherapy and combination treatments should have a more meticulous oral care. So there needs to be an appropriate assessment tool and prevention protocol for oral mucositis that considers related factors.

Primary hepatic sarcoma is a rare tumor, with fewer than 60 previously reported cases. It is thought to arise from hepatic connective tissue or vascular channels. The tumor is located usually in the intrahepatic area. Pedunculated or bulging lesion is also reported. We report a case of primary leiomyosarcoma of the liver occuring in a 62-year-old Korean woman. A pedunculated, 21 16 cm sized mass is located in the left lateral segment of the liver. Microscopically, the tumor is hypercellular and composed of elongated, partly pleomorphic spindle cells with blunt-ended nuclei, which are focally reactive for muscle specific actin. Mitotic figures are 5/10 high power fields (HPFs). No other primary site is recognized on clinical study.

Asian Oncology Nursing 2016;16(1):9-19
PURPOSE: The objective of this study was to analyze effect size of the intervention studies for posttraumatic growth in patients with cancer. METHODS: A total of 871 studies published between 2000 and 2014 were identified by searching Ovid-Medline, CINAHL, PubMed, Scopus, PsycARTICLES, Cochrane library, RISS, and KISS. 15 studies were selected for inclusion in the meta-analysis. Data were analyzed using the Comprehensive Meta-Analysis (CMA) Ver. 3 program and the effect sizes were shown using Hedges's g score. RESULTS: Intervention studies included 5 studies on Cognitive Behavioral Stress Management (CBSM), 4 studies for Mindfulness-Based Stress Reduction (MBSR), 2 studies for couple-based intervention, and 1 study each for health coaching, building resilience, yoga and painting intervention. The overall controlled effect size was 0.335 (95% CI=0.231, 0.438), using a fixed effects model. The most effective intervention was the couple-based intervention (0.368, 95% CI=-0.146, 0.883), followed by MBSR (0.340, 95% CI=0.172, 0.508) and CBSM (0.314, 95% CI=0.139, 0.490). CONCLUSION: Cancer is one of the most significant traumatic events that affect patients' lives, a few cancer patients have been known to have posttraumatic growth. Therefore it is necessary to consider nursing interventions to increase posttraumatic growth for cancer patients such as couple-based intervention, MBSR and CBSM.

Congenital self-healing reticulohistiocytosis (CSHRH) typically presents at birth or in the first few weeks of life as a widespread eruption of cutaneous red-brown papulonodules that resolve spontaneously without involvement of other organs. While multiple lesions are common, a solitary lesion is rare. We describe a solitary type of CSHRH in a full-term, male neonate. He had an erythematous papule with a yellowish crust on the left heel without any systemic symptoms. Four weeks later, the skin lesion had disappeared spontaneously.

9.Uterine Leiomyoma with Massive Lymphocytic Infiltration.
Korean Journal of Pathology 2003;37(1):71-73
Uterine leiomyoma with massive lymphocytic infiltration is known to be associated with Gona-dotropin releasing hormone (GnRH) agonist treatment. The lymphocytic cells in those cases were composed predominantly of T-lymphocytes. We report an unusual case of uterine leiomyoma with massive lymphocytic infiltration, composed predominantly of B-lymphocytes, without a history of GnRH agonist treatment. A 59-year-old woman underwent a transvaginal hysterectomy for uterine leiomyomas. Microscopically, the leiomyoma showed a massive infiltration of the lymphocytes, histiocytes, and also showed scattered plasma cells and many lymphoid follicles. The lymphocytic infiltrates were confined to the leiomyoma. These lymphocytic cells mainly represented the B-cell phenotype. She had no history of GnRH agonist treatment. To the best of our knowledge, This is the first reported case in Korea.

Immunohistochemical staining on paraffin sections for S-100 protein improved diagnostic accuracy for melanocytic tumor. But specificity of S-100 protein in the diagnosis of melanocytic tumor is very low, because S-100 protein was also expressed in neurogenic tumor and salivary gland tumor. To investigate a specific tumor marker for the malignant melanoma, immunohistochemical staining for HMB-45 and S-100 protein was performed on the paraffin sections of 25 cases of malignant melanoma and 46 cases of nevi. Positive reaction for HMB-45 and S-100 protein was diffusely identified in the cytoplasm of tumor cells. Positive ratio for HMB-45 was 100% in malignant melanoma, 92% in junctional component of compound nevus and 0% in intradermal nevus. Positive ratio for S-100 protein was 92% in malignant melanoma, 100% in compound nevus and 100% in intradermal nevus. The sensitivity and specificity for HMB-45 in malignant melanoma were 100%, but those for S-100 protein were 92% in sensitivity and 86.7% in specificity. These results indicate that HMB-45 has a high sensitivity and specificity for malignant melanoma cells and it can be quite useful for the histopathological diagnosis of malignant melanoma.
