The p53 gene is believed to play an important role through the mutation and overexpression in the progression of various human malignant tumors. The type IV collagenase (matrix metalloproteinase: MMP-2) initiates the degradation of the extracellular matrix, and consequently may play a role in the tumor invasion and metastasis. To investigate the correlation between clinicopathologic features of the colorectal adenocarcinomas and benign tumors and expression of p53 and MMP-2 proteins, we performed an immunohistochemical study on 40 colorectal adenocarcinomas, 20 adenomas and 20 hyperplastic polyps by using the antibodies to p53 and MMP-2 proteins. The positive expression rate of the p53 protein in adenocarcinomas was 62.5% and significantly higher than in benign tumors. The positive expression rate of the MMP-2 protein was 47.5% in adenocarcinomas, but there was no expression of MMP-2 protein in benign tumors. The difference in p53 and MMP-2 expression rates between malignant and non-malignant tumors was statistically significant. The positive expression rate of p53 protein in the non-metastatic and metastatic adenocarcinomas was 59.1 and 66.7%, respectively. The positive expression rate of MMP-2 protein in the non-metastatic and metastatic adencarcinomas was 45.5 and 50.0%, respectively. The correlation between several clinicopathologic features and expression of p53 and MMP-2 protein was not statistically significant, but the rate of positive MMP-2 immunoreactivity showed a statistically significant difference between Astler-Coller stage B1 C1 group and B2 C2 group of adenocarcinoma (p=0.0431). We concluded that the expression of p53 and MMP-2 protein contributes to the cancer development and MMP-2 may play a certain role in the invasiveness of the colorectal tumor. p53 and MMP-2 protein expression is not correlated with lymph node metastasis.

OBJECTIVE: To analyze 543 cases of amniocentesis with indications, cytogenetic results. METHOD: This study includes 543 cases cytogenetic study results which amniocentesis to detect fetal chromosomal abnormality in the Cytogenetic Laboratory at Eun Hospital in Kwang-Ju from August 1996 to December 2000, as gestational ages, indications of amniocentesis, maternal age distributions, chromosome aberrations with cytogenetic results. The cytogenetic results of chromosome aberration was identified by parents inheritance and de novo karyotypes as parents periperal blood cytogenetic study. RESULTS: Amniocentesis performed mostly from 15 weeks to 20 weeks of gestaional ages. Requested indication of amniocentesis presents abnormal maternal serum screening (37%), infertility (23%) and maternal old age (> or =35) (17%). Chromosome aberration according to amniocentesis indication was suspected fetal anomaly by ultrasonogram (8.6%), previous family history (5.7%). Chormosome aberration following maternal ages, more 40 years old women were found highly 7.9%. The frequency of chromosome aberration was 5.5% but de novo chromosome aberration was 2.2%. Numerical aberration was overall new karyotypes (1.3%). Structural aberration was inheritance karyotypes (3.3%) and de novo karyotypes (0.9%). CONCLUSION: Amniocentesis is a effective diagnostic tools in fetal chromosome aberration. Indication of fetal chromosomal anormality by ultrasonography and advanced maternal ages is an important diagnostic method with chromosome aberrations. Prenatal fetal chromosome aberrations included inheritance and de novo karyotypes. Especially, identification of de novo chromosome aberrations may predict fetal anomaly and counsel the fetus for pregnant parents.

PURPOSE: Streptococcus pyogenes is an important cause of invasive diseases in children. We aimed to describe the clinical characteristics of invasive infections due to S. pyogenes in children in Korea. METHODS: A retrospective study of children under 18 years of age with invasive infections due to S. pyogenes at Seoul National University Children's Hospital between March 1992 and December 2012, and Seoul National University Bundang Hospital between March 2003 and December 2012 was conducted. Demographic factors, clinical characteristics, laboratory findings, treatment, mortality and morbidity of all patients were reviewed. RESULTS: A total of 30 among 36 cases identified as invasive disease due to S. pyogenes were available for review. There was a predominance for male subjects (male:female=2.75:1). The median age was 50 months (range 12 days to 15 years) and 53.3% were under 5 years of age. Skin and soft tissue infections (9/30, 30.0%), bacteremia without identified focus (4/30, 13.3%) and bone and joint infections (6/30, 20.0%) were the most frequent clinical presentations. Streptococcal toxic shock syndrome (3/30, 10.0%) pulmonary, abdomen and central nervous system infections (2/30, 6.7%) were also seen. There was a peak in number of patients in year 2012 (9/30, 30.0%). There were no cases of mortality. Erythromycin and clindamycin resistance rates were low by 3.8% and 7.5%, respectively. CONCLUSION: We studied the clinical presentations of invasive infections due to S. pyogenes during the past 20 years in Korean children. The findings of this study help us understand the characteristics of the disease, enhancing early recognition and prompting adequate antibiotic therapy which is important in reducing morbidity and mortality.

OBJECTIVE: The main purposes of this study were to understand the correlations among Modified Barthel Index (MBI), Functional Independence Measure (FIM), and ESCROW (Environment, Social support, Cluster of family members, Resources, Outlook, Work or School status) Profile, and to establish the more appropriate assessment standards to check patient's conditions in the hospital and in their homes and society. METHOD: Thirty-four patients, who received the rehabilitation treatment and home visiting at the Presbyterian Medical Center, were evaluated for their functions by MBI, FIM, and ESCROW Profile. RESULTS: The mean scores of assessment measures by home visiting were all higher than in the hospital showing an improvement of the patients' functions after discharge from the hospital. The results of MBI and FIM in the hospital and home visiting showed a significant correlation, while the results of MBI and Cognitive FIM measure indicated a relatively low correlation coefficient. Although each result of MBI, FIM, and ESCROW provided a low correlation when the patients were in the hospital, the result for home visiting revealed very significant correlations. Especially, the items of environment, social support, outlook, and work status of ESCROW showed very significant correlations with MBI and FIM. CONCLUSION: The results showed that MBI and FIM measurements were very useful in observing and following up the functional conditions of the patients, while ESCROW profile was more appropriate to evaluate the familial and social rehabilitation status.

Melkersson-Rosenthal (M-R) syndrome consists of a triad of (1) recurrent peripheral facial nerve paralysis which develops alternatively on both sides of face, (2) non-inflammatory facial edema, and (3) furrowed tongue. Since the cause of M-R syndrome is unknown, various forms of therapy have been tried, but there were no conclusive evidence that they altered the course of the disease. A 27-year-old female and a 44-year-old male patient with recurrent facial nerve paralysis were diagnosed with M-R syndrome. We report the two cases of M-R syndrome with the brief review of literatures.

PURPOSE: The purpose of this study was to describe and explore the experience process of life of patients with Crohn's disease. METHODS: Using a grounded theory methodology, 24 interviews were performed with 7 men and 5 women, 17-47 years of age, suffering from Crohn's disease. RESULTS: 'Tuning of two conflicting lives' was identified as the core category, and 5 subcategories were identified and they were integrated into the core category. The identified outcomes were 'Living a withdrawn life', 'coping flexibly', 'drifting with tangled emotions' and 'maintaining long-term remission'. CONCLUSION: When caring for these patients, it is important to identify needs, allow patients to express what they want at that moment and support them in maintaining a daily life that can be perceived as normal.

A case of clear cell adenocarcinoma arising in the female urinary bladder, which is accompanied by endometriosis of the urinary bladder and the uterus, is reported. The carcinoma protruded into the vesical lumen as a fungating mass, and had a tubulocyotic pattern. The tumor cell had intracytoplasmic glycogen and electron microscopically short microvilli on their surface, resembling clear cell acenocarcinoma of the female genital tract including ovary. This is the fourth case report of clear cell adenocarcinoma complicating vesical endometriosis, and may support the view that clear cell carcinome arises from endometriosis which, in turn, from the Mullerian remnant.
