BACKGROUND: Rosacea is characterized by erythema of the central face that persists for several months or longer. Reports of the histological changes in rosacea are scarce, and few attempts have been made to correlate such changes with clinical findings and pathophysiology. OBJECTIVE: This study aimed to elucidate the clinical manifestations of rosacea and investigate its histological features. METHODS: We performed a retrospective analysis of 278 patients with histologically confirmed rosacea who visited the Department of Dermatology at the Catholic Medical Center between January 2008 and May 2013. Clinical subtypes, disease severity, and precipitating factors were evaluated. In 115 randomly selected patients, histopathological features were evaluated as well. RESULTS: The ratio of males to females was 1:1.8. The age distribution showed a peak incidence in the fifth decade. The most common subtype was papulopustular rosacea (52.9%) followed by erythematotelangiectatic rosacea (34.9%), ocular rosacea (4.0%), and phymatous rosacea (2.9%). Granulomatous rosacea accounted for 5.4% of rosacea cases. Precipitating factors included hot weather (54.7%), stress (51.8%), sun exposure (37.4%), alcohol (37.4%), and hot baths (33.1%). Histological analysis of skin biopsies from 115 patients revealed solar elastosis in 62 patients (53.9%) and telangiectasia in 85 patients (73.9%). CONCLUSION: In this study, Korean rosacea patients were predominantly female with a peak age in the fifth decade and the majority suffered from the papulopustular and erythematotelangiectatic types of rosacea. Histological observations pertaining to each rosacea type were also discussed.

Telomerase play a key role in the maintenance of telomere length and chromosome integrity. We have evaluated the association between telomerase activity and the risk of lung cancer in peripheral blood. Telomerase activity in peripheral blood mononuclear cells was measured by a PCR-designed telomeric repeat amplification protocol in 63 lung cancer patients and 190 healthy controls that were matched for age, gender, and smoking status. Telomerase activity was significantly lower in the lung cancer patients than in controls (mean +/- standard deviation; 1.32 +/- 1.65 vs 2.60 +/- 3.09, P < 1 x 10(-4)). When telomerase activity was categorized into quartiles based on telomerase activity in the controls, the risk of lung cancer increased as telomerase activity reduced (Ptrend = 1 x 10(-4)). Moreover, when the subjects were categorized based on the median value of telomerase activity, subjects with low telomerase activity were at a significantly increased risk of lung cancer compared to subjects with high telomerase activity (adjusted odds ratio = 3.05, 95% confidence interval = 1.60-5.82, P = 7 x 10-4). These findings suggest that telomerase activity may affect telomere maintenance, thereby contributing to susceptibility to lung cancer.

PURPOSE: Due to the availability of serum prostate specific antigen (PSA) testing, the detection rate of insignificant prostate cancer (IPC) is increasing. To ensure better treatment decisions, we developed a nomogram to predict the probability of IPC. MATERIALS AND METHODS: The study population consisted of 1,471 patients who were treated at multiple institutions by radical prostatectomy without neoadjuvant therapy from 1995 to 2008. We obtained nonrandom samples of n = 1,031 for nomogram development, leaving n = 440 for nomogram validation. IPC was defined as pathologic organ-confined disease and a tumor volume of 0.5 cc or less without Gleason grade 4 or 5. Multivariate logistic regression model (MLRM) coefficients were used to construct a nomogram to predict IPC from five variables, including serum prostate specific antigen, clinical stage, biopsy Gleason score, positive cores ratio and maximum % of tumor in any core. The performance characteristics were internally validated from 200 bootstrap resamples to reduce overfit bias. External validation was also performed in another cohort. RESULTS: Overall, 67 (6.5%) patients had a so-called "insignificant" tumor in nomogram development cohort. PSA, clinical stage, biopsy Gleason score, positive core ratio and maximum % of biopsy tumor represented significant predictors of the presence of IPC. The resulting nomogram had excellent discrimination accuracy, with a bootstrapped concordance index of 0.827. CONCLUSION: Our current nomogram provides sufficiently accurate information in clinical practice that may be useful to patients and clinicians when various treatment options for screen-detected prostate cancer are considered.

We investigated the clinical significance of large difference (> or = 2 points) between biopsy-derived (bGS) and post-prostatectomy Gleason scores (pGS). At 14 medical centers in Korea, 1,582 men who underwent radical prostatectomy for prostate cancer were included. According to the difference between bGS and pGS, the patients were divided into three groups: A (decreased in pGS > or = 2, n = 30), B (changed in pGS < or = 1, n = 1,361; control group), and C (increased in pGS > or = 2, n = 55). We evaluated various clinicopathological factors of prostate cancer and hazards for biochemical failure. Group A showed significantly higher mean maximal percentage of cancer in the positive cores (max%) and pathological T stage than control. In group C, the number of biopsy core was significantly smaller, however, tumor volume and max% were significantly higher and more positive biopsy cores were presented than control. Worse pathological stage and more margin-positive were observed in group A and C than in control. Hazard ratio for biochemical failure was also higher in group A and C (P = 0.001). However, the groups were not independent factors in multivariate analysis. In conclusion, large difference between bGS and pGS shows poor prognosis even in the decreased group. However it is not an independent prognostic factor for biochemical failure.

BACKGROUND/AIMS: In Korea, few studies have examined primary cardiac tumors, which have a reported incidence of 0.0017~0.19% in autopsy series. This study surveyed the status of primary cardiac tumors over the past 7 years in one region. METHODS: A retrospective review examined all patients with primary cardiac tumors, except for confirmed thrombus, using hospital medical records from 2000 to 2006 at six community hospitals. Identified cases undergoing biopsy and surgery were selected for the study. RESULTS: The operative mortality was 7.7%. Of the 71 patients (26 males) with identified primary cardiac tumors, 65 (91.5%) tumors were benign and 6 (8.5%) were malignant. The benign tumors were myxoma (78.9%), rhabdomyoma (4.2%), fibroelastoma (2.8%), fibroma (1.4%), and leiomyoma (1.4%). Two of the myxomas were present at multiple locations. The malignant tumors included sarcomas (67%) and lymphomas (33%). Most of the tumors were located in the left atrium (76%). The majority of patients presented with chest pain and dyspnea. During follow-up for an average of 26.8+/-21.3 months, all but one patient with benign tumors was alive; one myxoma patient died perioperatively (1.5%). Four of the patients with malignant tumors (67%) died. CONCLUSIONS: Cardiac myxomas and sarcomas were the most common primary benign and malignant tumors, respectively. Benign tumors had excellent postoperative survival rates, while malignant tumors had high mortality.

We developed a nomogram to predict the probability of extracapsular extension (ECE) in localized prostate cancer and to determine when the neurovascular bundle (NVB) may be spared. Total 1,471 Korean men who underwent radical prostatectomy for prostate cancer between 1995 and 2008 were included. We drew nonrandom samples of 1,031 for nomogram development, leaving 440 samples for nomogram validation. With multivariate logistic regression analyses, we made a nomogram to predicts the ECE probability at radical prostatectomy. Receiver operating characteristic (ROC) analyses were also performed to assess the predictive value of each variable alone and in combination. The internal validation was performed from 200 bootstrap re-samples and the external validation was also performed from the another cohort. Overall, 314 patients (30.5%) had ECE. Age, Prostate specific antigen (PSA), biopsy Gleason score, positive core ratio, and maximum percentage of biopsy tumor were independent predictors of the presence of ECE (all P values <0.05). The nomogram predicted ECE with good discrimination (an area under the ROC curve of 0.777). Our nomogram allows for the preoperative identification of patients with an ECE and may prove useful in selecting patients to receive nerve sparing radical prostatectomy.

BACKGROUND: Considering the unhealthy lifestyle observed in divorced men, we planned this study to compare the lifestyle and cardiovascular risk factors between married and divorced man. METHODS: A total of 11,855 male workers took a health check-up in a University Hospital in Ulsan from March to December 2004. One hundred eight workers were recognized to have checked affirmative on "divorced" check item on the marital status and 400 workers were matched for age and randomly selected from the "married" 10,177 workers. Comparison was performed between the two groups with the results of the main laboratory data and self-recorded life style questionnaire. RESULTS: The divorced men were shorter in height than the married men (P = 0.022), and showed significantly higher diastolic blood pressure (P = 0.033) and gamma-glutamyl transferase (P = 0.001). In lifestyle, the divorced men had significantly lower educational level, lower monthly household income, higher smoking rate, and more frequent irregular meals than the married men. Divorcing had 1.88 times the odds of having higher diastolic blood pressure compared to staying married. CONCLUSION: The divorced men had poorer lifestyle and higher diastolic blood pressure than the married men.

BACKGROUND: According to previous epidemiologic studies, the metabolic syndrome, dietary and lifestyle factors were associated with colon polyps. The aim of this cross-sectional study was to assess the relationship between the risk of the colorectal adenoma incidence and the individual components of the metabolic syndrome with lifestyle factors such as drinking, cigarette smoking and physical activity. METHODS: Sigmoidoscopic examination for colon cancer screening was performed from January 2002 to December 2003 at the Health Promotion Center of Ulsan University Hospital in Ulsan, Korea. A total of 1,565 subjects underwent satisfactory sigmoidoscopy. The subjects with a history of colon cancer or polyps or inflammatory bowel disease were excluded from the study. Alcohol consumption, cigarette smoking and other confounding factors were included as covariates in the models. RESULTS: After adjusting for age, physical activity,smoking and alcohol intake, the subjects of metabolic syndrome (> or =3 vs. 0 components) combined with cigarette smoking had a positive association with colorectal adenoma incidence (OR 3.63, 95% CI 1.49~8.89). Physical activity was negatively associated the risk of the colorectal adenoma incidence (OR 0.60 95% CI 0.44~0.81). CONCLUSION: These results suggest that clustering of components of the metabolic syndrome combined with cigarette smoking significantly increased the colorectal adenoma risk, but physical activity reduced the risk of colorectal adenoma incidence in Korean adult males after multivariate adjustment.

Kaposi sarcoma is a rare tumor originated from skin in patients with immune suppressive illness like as acquired immunodeficiency syndrome (AIDS) or organ transplantation. It may be widely disseminated internally such as digestive or respiratory organ. In Korean patients with AIDS, Kaposi sarcoma is rarely seen rather than western countries. The reason is unknown. Although few cases of Kaposi sarcoma in patients with AIDS had been described in the Korean literatures, multi-organ involved cases were extremely rare. We describe a case of old AIDS patient in whom Kaposi sarcoma had affected multi-organs including esophagus, stomach, duodenum, colon, bronchi and skin.

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.
