OBJECTIVES: Paraoxonase is a high-density-lipoprotein- associated enzyme capable of hydrolysing lipid peroxides. Thus it might protect lipoproteins from oxidation. It has two isoforms, which arise from a glutamine (A isoform) to arginine (B isoform) interchange at position 192. More recently, Ruiz et al. investigated the relationship between the paraoxonase genetic polymorphism and coronary heart disease in a case-control study of NIDDM in France. We investigated the correlation between the polymorphism of paraoxonase gene and cardiovascular disease in Korean diabetic patients. METHODS: Of 106 patients with NIDDM, 50 had confirmed cardiovascular disease (coronary heart disease or ischemic stroke). The other 56 patients had no history of such disease and ECG abnormality. An additional control group of non-diabetic, healthy subjects (N=55) was selected. The polymorphism of paraoxonase gene was assessed by PCR-RFLP in their blood leukocytes DNA. RESULTS: The healthy control revealed paraoxonase genotype frequencies of 18.1% AA, 36.4% AB and 45.5% BB. The NIDDM group revealed paraoxonase genotype frequencies of 11.3% AA, 39.6% AB, 49.1% BB. The genotype frequencies did not differ between healthy control with diabetic group. The genotype frequencies did not differ between diabetic group with coronary heart disease and diabetic control group (AA ; 8.4% vs 12.5%, AB ; 45.8% vs 37.5%, BB ; 45.8% vs 50.0%). There was also no difference in genotype frequencies between diabetic group with ischemic stroke and diabetic control (AA ; 11.5% vs 12.5%, AB ; 38.5% vs 37.5%, BB ; 50.0% vs 50.0%). In multiple logistic regression analysis with other risk factors, hypertension emerged as the most related factors for cardiovascular disease, but paraoxonase genotype was not associated with the presence of cardiovascular disease. CONCLUSION: In Korean diabetic patients, the polymorphism of paraoxonase gene might not be associated with the presence of coronary heart disease or ischemic stroke.

BACKGROUND AND OBJECTIVES: Koufman described a pseudocyst of the vocal folds for the first time in 2001. A pseudocyst in all parts of the body and that is related to secretory glands is already well known, but such a lesion of the vocal folds has only been mentioned a few times. It is unclear whether or not to define a pseudocyst of the vocal folds as a benign lesion of the vocal folds. The objective of this study was to introduce the demographic and clinical findings of pseudocyst and to discuss our diagnostic and therapeutic strategies. SUBJECTS AND METHOD: We carried out a retrospective review of all the medical records, the preoperative voice lab results and the operation records from 2006 to 2009. All the patients underwent laryngomicrosurgery due to benign vocal folds lesions. We select 11 cases that showed subepithelial lesion without a definite capsule. RESULTS: Seven patients had had the history of voice abuse. One patient has been a smoker, another was an ex-smoker and the others were non-smokers. According to aerodynamic assessment, the maximum phonation time was 14.6 seconds and the mean airflow was typically increased. On laryngoscopy, all were translucent and spherical or fusiform subepithelial lesions. The preoperative stroboscopic findings showed a uniform feature of damping on the vocal fold lesion. Both the unroofing technique and the microflap technique were used. CONCLUSION: A pseudocyst would be a subepithelial lesion without a definite epithelial lining that contains serous discharge. We suggest that a pseudocyst of the vocal fold is a new benign lesion.

BACKGROUND AND OBJECTIVES: Regional recurrence of head and neck squamous cell carcinoma (HNSCC) is the most common single type of treatment failure, and thus a challenging problem for the clinician. When planning management of regional recurrence, the grave outcome of the recurrence itself, and benefits and morbidity owing to the intervention must be taken into account. We analyzed the factors affecting salvage treatment outcomes of regional recurrence in head & neck squamous cell carcinoma. SUBJECTS AND METHOD: A retrospective analysis of medical records over a 10 year period (1994-2003) was conducted. Sixty-two patients with regional and locoregional recurrence were identified. Patients with local recurrence or distant metastasis were excluded. RESULTS: The median age of the population was 62 years. Sixty percent of the cases were regional, and the remainders were locoregional recurrences. The median time of recurrence was 16 months with an overall survival rate of 46.1%. Recurrence in a surgically virginal neck was associated with a favorable outcome. Factors associated with poor outcomes were node positive at initial presentation, neck dissection at initial treatment, recurrence at contralateral neck, incorporation of chemotherapy for salvage treatment, and subsequent recurrence after salvage treatment. CONCLUSION: In the management of patients with regional recurrence of HNSCC, the factors mentioned above should be taken into consideration regarding patient selection, salvage management plan, and patient counseling.

PURPOSE: Thymidylate synthase (TS) is a critical enzyme in the DNA synthesis and an important target of cancer chemotherapeutic agents, such as 5-fluorouracil (5-FU). Recent studies suggest that TS expression is related to the prognosis of various cancers and the mechanism of chmotherapeutic drug resistance. This retrospective study was performed to determine whether TS expressions in primary colorectal tumors influence the overall survival and recurrence for patients with colorectal cancer. METHODS: Intratumoral TS expression was evaluated by immunohistochemical staining using TS-106 monoclonal antibody in primary colorectal cancers of 64 patients who had undergone surgery from July, 1995 to June, 1999. The relationship between TS expressions and patients' survival was evaluated statistically. The median follow-up period was 25.7 months. RESULTS: Overall positive TS expression rate was relatively high (54.7%) in colorectal cancers, and overall disease-free survival rate was significantly higher in the TS positive group (P=0.0204). But there was no statistically significant differences in overall survival rates (P=0.249) and tumor recurrence rates (P=0.732) between positive TS group and negative TS group. CONCLUSIONS: These results suggest that TS expression status in the colorectal cancer tissue is only related to the overall disease-free survival rates, not the overall survival rates and tumor recurrence rates. More objective method and long term follow up study will be required for accurate assessment of clinical importance of TS expression in colorectal cancers.

Objectives: . We aimed to assess the genetic differences between cases of early-stage tongue cancer that were positive or negative for lymph node metastasis. Methods: . In total, 35 cases of tongue cancer with RNA sequencing data were enrolled in this study. The gene expression profile of the following two groups was compared: N0 group (T stage 1 or 2 with N0 stage) and N+ group (T stage 1 or 2 with N+ stage). Using the R and limma packages in the Bioconductor program, we extracted the differentially expressed genes (DEGs). Gene ontology and pathway enrichment analysis were performed using the Database for Annotation, Visualization and Integration Discovery (DAVID) online tool. Immune cell infiltration was analyzed using the CIBERSORT online program. Immunochemical staining of the cancer tissue was evaluated and The Cancer Genome Atlas (TCGA) data were analyzed to validate the identified DEGs. Results: . No significant differences were found in the infiltration of 22 types of immune cells. Among a total of 51 identified DEGs, 14 genes were significantly upregulated, while 37 genes were significantly downregulated (P<0.01; fold change >2). Pathway analysis revealed significant associations with the arachidonic acid metabolism-related pathway, calcium signaling, and the muscle contraction pathway. The following DEGs were the most significantly different between the two groups: DEFB4A, SPRR2B, DEFB103B, SPRR2G, DEFB4B, and FAM25A. TCGA data showed that DEFB4A and DEFB103B were more highly expressed in the N0 group than in the N+ group, although the difference did not achieve statistical significance. Immunochemical staining of cancer tissue revealed significantly higher expression of defensin in the N0 group. Conclusions . Defensin (DEFB4A, DEFB103B, DEFB4B) may be a novel biomarker for early regional metastasis in T1/2 tongue cancer.
