BACKGROUND: When patients with diabetes mellitus (DM) are first referred to a hospital from primary health care clinics, physicians have to decide whether to administer an oral hypoglycemic agent (OHA) immediately or postpone a medication change in favor of diabetes education regarding diet or exercise. The aim of this study was to determine the effect of diabetes education alone (without alterations in diabetes medication) on blood glucose levels. METHODS: The study was conducted between January 2009 and December 2013 and included patients with DM. The glycosylated hemoglobin (HbA1c) levels were evaluated at the first visit and after 3 months. During the first medical examination, a designated doctor also conducted a diabetes education session that mainly covered dietary management. RESULTS: Patients were divided into those who received no diabetic medications (n=66) and those who received an OHA (n=124). Education resulted in a marked decrease in HbA1c levels in the OHA group among patients who had DM for <1 year (from 7.0%±1.3% to 6.6%±0.9%, P=0.0092) and for 1 to 5 years (from 7.5%±1.8% to 6.9%±1.1%, P=0.0091). Those with DM >10 years showed a slightly lower HbA1c target achievement rate of <6.5% (odds ratio, 0.089; P=0.0024). CONCLUSION: For patients who had DM for more than 5 years, higher doses or changes in medication were more effective than intensive active education. Therefore, individualized and customized education are needed for these patients. For patients with a shorter duration of DM, it may be more effective to provide initial intensive education for diabetes before prescribing medicines, such as OHAs.

During civil engineering construction near Sejong-ro, Jongro-ku, Seoul, cultural sites were found that are thought to have been built in the 15th century. This area was home to many different people as well as the leaders of the Yi dynasty. To gain further insight into the life styles of the inhabitants of the old capital, soil samples were collected from various areas such as toilets, water foundations, and drainage ways. Parasite eggs were examined by microscopy after 5 g soil samples were rehydrated in 0.5% trisodium phosphate solution. A total of 662 parasite eggs from 7 species were found. Species with the highest number of eggs found were Ascaris lumbricoides (n=483), followed by Trichuris trichiura (138), Trichuris vulpis (21), Fasciola hepatica (8), Clonorchis sinensis (6), Paragonimus westermani (4), and Metagonimus yokogawai (2). These findings indirectly indicate the food habits of the people in Yi dynasty.

Ursolic acid (UA) supplementation was previously shown to improve skeletal muscle function in resistance-trained men. This study aimed to determine, using the same experimental paradigm, whether UA also has beneficial effects on exercise-induced skeletal muscle damage markers including the levels of cortisol, B-type natriuretic peptide (BNP), myoglobin, creatine kinase (CK), creatine kinase-myocardial band (CK-MB), and lactate dehydrogenase (LDH) in resistance-trained men. Sixteen healthy participants were randomly assigned to resistance training (RT) or RT+UA groups (n=8 per group). Participants were trained according to the RT program (60~80% of 1 repetition, 6 times/week), and the UA group was additionally given UA supplementation (450 mg/day) for 8 weeks. Blood samples were obtained before and after intervention, and cortisol, BNP, myoglobin, CK, CK-MB, and LDH levels were analyzed. Subjects who underwent RT alone showed no significant change in body composition and markers of skeletal muscle damage, whereas RT+UA group showed slightly decreased body weight and body fat percentage and slightly increased lean body mass, but without statistical significance. In addition, UA supplementation significantly decreased the BNP, CK, CK-MB, and LDH levels (p<0.05). In conclusion, UA supplementation alleviates increased skeletal muscle damage markers after RT. This finding provides evidence for a potential new therapy for resistance-trained men.

Pulmonary toxicity is one of the most serious adverse effects associated with a quick course of vincristine, bleomycin, and cisplatin neoadjuvant chemotherapy (NAC-VBP). The aim of this study was to evaluate pulmonary toxicity related to a quick course NAC-VBP. A total of consecutive 61 patients, who underwent at most 3 cycles of NAC-VBP every 10 days in the International Federation of Gynecology and Obstetrics (FIGO) stage IB-IIB cervical cancer from 1995 to 2007, were retrospectively analyzed. Of the 61 study subjects, 7 (11.5%) were identified to have pulmonary toxicity and 2 (3.3%) died of pulmonary fibrosis progression despite aggressive treatment and the use of a multidisciplinary approach. No factor predisposing pulmonary toxicity was identified. Initial symptoms were non-specific, but bronchiolitis obliterans organizing pneumonia and interstitial pneumonitis were characteristic findings by high-resolution computed tomography of the chest. The benefit of steroid therapy was uncertain and was associated with steroid-induced diabetes mellitus requiring insulin therapy in two patients. Fatal pulmonary toxicity is a major concern of a quick course NAC-VBP. In conclusion, these patients require special monitoring for bleomycin-induced pulmonary toxicity.

OBJECTIVE: To define the molecular basis of TGF-beta1 function in cervical carcinogenesis, we explored the expression and mutational status of TGF-beta1, TGF-beta1 receptors, and Smads, the regulators of the TGF-beta1 signaling pathway, in human cervical cancers. METHODS: Expression of TGF-beta1, TGF-beta1 receptors, and Smads transcripts were determined by quantitative reverse transcription-polymerase chain reaction (RT-PCR), and sequence alteration was analyzed using RT-PCR-single-strand conformation polymorphism (SSCP) analysis. Genomic levels of TGF-beta1, TGF-beta1 receptors and Smads was also measured by quantitative genomic PCR. RESULTS: Abnormal overexpression of TGF-beta1 and abnormal reduction of type II TGF-beta1 receptor were identified in 36% (18 of 50) and 20% (10 of 50) of cervical cancer tissues, respectively. 22% (11 of 50) in Smad2 and 14% (7 of 50) in Smad4 revealed tumor specific mRNA reduction less than a half of normal means. In addition, no evidence for sequence alterations of the gene was found by RT-PCR-SSCP analysis. CONCLUSION: Our study demonstrates that disruption of TGF-beta/Smad signaling pathway exist in human cervical cancer, suggesting that abnormal expressions of the member of TGF-beta/Smad signaling pathway might contribute to the malignant progression of human cervical tumors via suppressing the tumor suppression function of TGF-beta1 1's tumor suppression function.

Approximately 5-30% of the ovarian cancers are metastatic malignancies. The prevalence of metastatic ovarian tumors varies with the incidence rates and spread patterns of primary malignancies. We evaluated the prevalence, pre- and postoperative characteristics of metastatic ovarian cancer in Korean women. We reviewed the records for 821 ovarian malignancies with pathological consultation from 1996- 2006 and recorded patient demographical, radiological, histopathological, and survival data. The study included 112 cases of histologically confirmed metastatic ovarian cancer. Metastatic ovarian cancer accounted for 13.6% of all ovarian malignancy, primarily arising from the gastrointestinal tract. The preoperative detection rate with imaging was 75%, and none of the radiological or serological features were useful for differential diagnosis. In multivariate analysis for prognostic variables, the only significant factor was the primary tumor site (p=0.004). Furthermore, extensive resection increased survival for some patients. The differential diagnosis of metastatic ovarian cancer can be problematic, so multiple diagnostic approaches are necessary. The extent of cytoreductive surgery for this type of tumor must be decided on a case-by-case basis.

OBJECTIVE: To evaluate the relationship between single nucleotide polymorphisms (SNPs) in the HER-2 gene and age on the risk and pathologic feature of endometrial cancer. METHODS: We included 125 women with histologically confirmed endometrioid adenocarcinoma who underwent complete surgical staging. The control group consisted of 302 patients with benign gynecologic disease who underwent hysterectomy. Nine SNPs spanning the HER-2 gene were genotyped by SNP-IT assay using SNPstream(r) Genotyping System. Of 9 SNPs, 5 that were either monomorphic or had a lowallele frequency (<10%) in this population were removed, leaving 4 SNPs (SNP1- rs1801200, SNP2- rs1810132, SNP3- rs2517951, SNP4- rs1058808) with allele frequencies > or =10%; these were included in the final analysis. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) after adjustment for BMI. RESULTS: The mean age for endometrial cancer patients was 53.4+/-11.5 (range, 29-81) years. Forty-seven patients (38%) were <50 years of age, and 78 patients (62%) were > or =50 years. Cases had a significantly higher BMI than controls (P<0.001). After adjustment for BMI, there was no significant relationship between HER-2 polymorphism and the risk of endometrial cancer based on age. Furthermore, HER-2 polymorphism did not affect the pathologic features of endometrial cancer based on age. CONCLUSION: Although there is no potential association among HER-2 polymorphisms, age, and endometrial cancer risk, large studies are needed in the future to assess the role of this polymorphism in endometrial cancer and for its combined effect.

OBJECTIVE: Cancer metastasis is a complex process involving a sequential series of multi-step genetic events, which produces an imbalance between stimulatory and inhibitory genes for metastasis. Presently, we examined the expression of metastatic tumor antigen 1 (MTA1) and nonmetastatic protein 23 homologue H1 (nm23-H1) proteins in metastasized epithelial ovarian cancer cells. METHODS: Fifty-one primary epithelial ovarian tumors and corresponding lymph nodes (LNs) were examined immunohistochemically for expression of MTA1 and nm23-H1. Expression of these proteins was statistically evaluated. RESULTS: The frequency of MTA1 expression was 30.3% (10/33) in stage III/IV LNs but was absent (0/18) in stage I/II LNs (p=0.01). MTA1 expression was observed in 50% (6/12) of metastasizing LNs but in only 10.3% (4/39) of non-metastasizing LNs (p=0.01). In contrast with MTA1, nm23-H1 expression was evident in 16 of 18 (88.9%) stage I/II ovarian cancer tissue samples but only in 20 of 33 (60.6%) stage III/IV tissues (p=0.05), and nm23-H1 production was also observed in 75.6% (34/45) of ovarian cancer tissue with residual tumors under 2 cm in diameter, but in 2/6 (33.3%) of cancer tissue with residual tumors exceeding 2 cm in diameter (p=0.03). CONCLUSION: The degree of expression and imbalance of MTA1 and nm23H1 are correlated with ovarian cancer LN metastasis.

OBJECTIVE: The abnormal expression of fragile histidine triad (FHIT) gene has been frequently reported in a variety of epithelial malignancies including cervical carcinoma. Furthermore, in a recent study it was proposed that transcriptional inactivation of FHIT, as a consequence of aberrant 5'-CpG island methylation, plays an important role in the carcinogenesis of human cervical carcinoma. The authors sought to determine whether abnormal FHIT transcription occurs in human cervical carcinoma, and if so, whether this abnormal expression is associated with aberrant 5'-CpG island methylation. In addition, the clinical significance of FHIT inactivation was investigated in Korean women with cervical cancer. METHODS: To examine for abnormal transcripts of the FHIT gene, quantitative RT-PCR, genomic DNA-PCR and nonisotopic RT-PCR-SSCP analysis were performed using the standard method. The methylation status was determined by methylation specific PCR and bisulfite DNA sequencing. RESULTS: The FHIT gene was down-regulated in 15 of 58 (25.9%) cervical carcinomas. FHIT promoter hypermethylation was detected in 15 of 15 (100%) abnormally expression in cervical carcinomas. Bisulfite DNA sequencing confirmed these findings and a significant correlation was found between CpG site hypermethylation and low FHIT expression. However, no significant correlation was found between reduced FHIT expression and clinicopathological characteristics. CONCLUSION: In this study, FHIT inactivation in cervical cancer was found to be strongly correlated with 5'-CpG island hypermethylation rather than a genetic alteration. Furthermore, no significant relation was found between a lack of FHIT expression and the prognostic factors of cervical cancer in our Korean cohort.
