Deregulation of G1 cyclins has been reported in several human and rodent tumors including colon cancer. To investigate the expression pattern of G1 cyclins in 1,2- dimethyl-hydrazine dihydrochloride (DMH)-induced rat colon carcinogenesis, we studied the expression of cyclin D1 and cyclin E by quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis and immunohistochemistry (IHC). The mRNA level of cyclin D1 was increased 1.2-fold in adenocarcinomas but not significantly in adenomas, when compared with normal rat colonic mucosa (p<0.05). The cyclin E mRNA level was increased 2.7-fold in adenomas and 3.3-fold in adenocarcinomas (p<0.05). The PCNA mRNA level was also increased 1.9-fold in adenomas and 1.8-fold in adenocarcinomas (p<0.05). Immunohistochemical staining revealed exclusive nuclear staining of the neoplastic cells for cyclin D1, cyclin E and PCNA. Cyclin D1 expression was detected in 56.3% of the adenomas and in 61.5% of the adenocarcinomas examined, whereas cyclin E expression was detected in 87.5% of the adenomas and in 92.3% of the adenocarcinomas. Overall, cyclin D1, cyclin E and PCNA expression was significantly increased at both the mRNA and protein levels in normal colonic mucosa, adenomas and adenocarcinomas, but there was no significant difference in the degree of expression of these genes in adenomas and adenocarcinomas. Our results indicate that the overexpression of cyclin D1 and cyclin E may play an important role during the multistage process of rat colon carcinogenesis, at a relatively early stage, and may disturb cell-cycle control in benign adenomas, and thereafter, participate in tumor progression.

Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

BACKGROUND/AIMS: Periostin is an extracellular matrix protein and is known to be related to the metastatic potential and prognosis of cancer. However, few studies have investigated the expression level of periostin and its association with prognoses in hepatocellular carcinoma. Therefore, we analyzed periostin overexpression in hepatocellular carcinoma and its implication for prognoses. METHODS: We evaluated 149 patients who underwent surgical resection between 2006 and 2010. Tissue microarrays were constructed from hepatocellular carcinoma tissue and adjacent nontumor tissue, and immunohistochemistry was performed. RESULTS: A high periostin level was observed more frequently in cases of multiple tumors (odds ratio [OR], 2.826; 95% confidence interval [CI], 1.224 to 6.527; p=0.013), positive microvascular invasion (OR, 2.974; 95% CI, 1.431 to 6.181; p=0.003), and advanced stage disease (OR, 3.032; 95% CI, 1.424 to 6.452; p=0.003). Patients with high periostin expression had significantly (p=0.002) lower overall survival rates than those with low periostin expression (90.3%, 66.1%, and 56.2% vs 97.7%, 85.1%, and 77.5% at 1, 3, and 5 years). CONCLUSIONS: We found that a combination of periostin overexpression and microvascular invasion in hepatocellular carcinoma was correlated with a poor prognosis and can be a good prognostic marker for hepatocellular carcinoma.

Neointimal hyperplasia mainly develops within several months of coronary stent deployment, after which it stabilizes. Although it was widely accepted, particularly during the bare-metal stent (BMS) era, that in-stent restenosis (ISR) generally does not present as an acute coronary syndrome (ACS), but rather as a gradual recurrence of angina symptoms, recent data have shown that a substantial number of patients with ISR present as ACS. There has also been consistent postmortem evidence of plaque rupture secondary to atherosclerotic change within the neointima of a BMS. We report here a case of ACS in which intravascular ultrasound and optical coherent tomographic assessments revealed neointimal atherosclerotic change and ruptured plaque 10 years after BMS deployment.

BACKGROUND: Chemerin is a novel adipokine that is associated with inflammation and adipogenesis. However, it remains unclear whether chemerin is involved in patients with cardiovascular disease. We investigated whether the serum chemerin levels of Korean patients with coronary artery disease correlated with specific cardiometabolic parameters. METHODS: In total, 131 patients, all of whom had coronary artery stenosis exceeding 50%, participated in this study. Their serum chemerin levels and cardiometabolic parameters were measured. The serum chemerin levels of two groups of patients were compared; those with one stenotic vessel (n=68) and those with multiple stenotic vessels, including left main coronary artery disease (n=63). RESULTS: Serum chemerin levels correlated positively with the degree of coronary artery stenosis and fasting glucose, triglyceride, total cholesterol, low density lipoprotein cholesterol, and high sensitive C-reactive protein levels. The group with multiple stenotic vessels, including left main disease, had higher chemerin levels than the group with one stenotic vessel (t=-2.129, P=0.035). Multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease (odds ratio, 1.018; confidence interval, 0.997 to 1.040; P=0.091). CONCLUSION: Serum chemerin levels have a significant correlation with several cardiometabolic risk factors and the degree of coronary artery stenosis in Korean patients with coronary artery disease. However, multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease. Additional investigations are necessary to fully elucidate the role of chemerin in cardiovascular disease.

PURPOSE:This study was performed to investigate clinical characteristics and the etiology of cervical lymphadenopathy in children. METHODS:A clinical review of 240 cases of children under the age of 18 who were admitted with cervical lymphadenopathy from January 2002 to December 2007. RESULTS:Cervical lymphadenopathy was diagnosed as follows:clinically diagnosed lymphadenitis (52.1%), abscess (15%), necrotizing lymphadenitis (7.9%), reactive hyperplasia (5.4 %), tuberculous lymphadenitis (4.2%), Kawasaki disease (2.9%) and malignancy (2.5%). Abscess was presented as an acute lesion (94.1%) with less than 2 weeks of fever (69.4 %) and tuberculous lymphadenitis was presented as a chronic lesion (62.5%) without fever (90 %). Malignant disease (100%) and necrotizing lymphadenitis (62.5%) were found in chronic lesion of older children with systemic symptoms (40% and 37.5%, respectively). Leukopenia (57.9%) with various duration of fever occured in case of necrotizing lymphadenitis. CONCLUSION:Clinically diagnosed lymphadenitis (52.1%), abscess (15%), necrotizing lymphadenitis (7.9%), reactive hyperplasia (5.4%), tuberculous lymphadenitis (4.2%), Kawasaki disease (2.9%) and malignancy (2.5%) were found in cervical lymphadenopathy. Although cervical lymphadenopathy was commonly caused by a benign infectious process, a more serious disease was not rare, which may have different clinical characteristics including age, duration of fever and disease, previous or accompanying symptoms, or white cell counts. Meticulous combination of clinical characteristics, history, physical examination and workup as well as follow-up may be the most important for the proper approach on cervical lymphadenopathy in children.

BACKGROUND/AIMS: Hilar cholangiocarcinoma is a tumor with poor prognosis although curative surgical resection is known to be the most effective treatment. To obtain negative resection margin is still a challenging problem for surgeons. We designed this study to investigate further the treatment strategies of the hilar cholangiocarcinoma by comparing the prognosis of patients managed by different modalities with special emphasis on the polarity of the resection margin. METHODS: A retrospective clinical study was performed at the Inha University Hospital for 70 patients managed for hilar cholangiocarcinoma from June 1996 to May 2002. RESULTS: The patients consisted of 45 men and 25 women. The average age of the patients was 66.4 years old. The survival rate for 1 year and 3 years and the median survival period were investigated. For the negative resection margin sub-group, those were 100%, 28.6% and 23 months respectively, while those for the positive resection margin sub-group were 70.6%, 10.8% and 19 months respectively. For the palliative bypass surgery sub-group, those were 0%, 0%, and 5 months, for the biliary stent sub-group, those were 5.3%, 0% and 5 months and for the intraductal radiotherapy sub-group, those were 20%, 0% and 7 months respectively. When the patients were divided between the resection and the non- resection groups, those figures were 79.2%, 12.1% and 20 months for the resection group while for the non-resection group, those were 11.9%, 0% and 6 months respectively. Statistical analysis showed that the survival rates for the resection and the non-resection groups were different (p=0.0001). However, the survival difference for the negative and the positive resection margin sub-groups were insignificant (p= 0.2401). For the three sub-groups of the non-resection group, the survival difference for each sub-groups were also insignificant (p=0.2979). Postoperative complication was observed in 12 patients (38.7%). Three patients died and the postoperative mortality rate was 9.7%. CONCLUSION: To improve the survival of the hilar cholangiocarcinoma patients, it is believed that the best treatment is the aggressive resection of the tumor even if it is difficult to obtain negative resection margin. Considering the high morbidity and mortality rate of extensive surgery and comparable survival of the positive resection margin patients, further extension of the extent of resection to obtain negative resection margin should be performed in selected patients.
