BACKGROUND: The incidence of colorectal polyps have been reported to be increasing in those aged 30-40 years who consume fast food, have low physical activity, and use alcohol and cigarettes. We analyzed the characteristics and risk factors of colorectal polyps in asymptomatic adults in Jeju Island. METHODS: Data on 1700 individuals who underwent a screening colonoscopy from 1 July, 2010 to 30 June, 2012 were analyzed based on age, gender, body mass index (BMI), blood pressure, blood tests, and behavioral habits including alcohol use, smoking, and exercise. RESULTS: The prevalence of colorectal polyps, including adenomatous and hyperplastic, is 43.1% and is higher in males (P<0.001). The prevalence according to age group shows increasing by age (P for trend<0.001). The most common histologic type of polyp is adenomatous in the <50 years and >50 years age groups, 27.3% and 45.3% respectively. And the percentage of adenomatous polyps has shown an increasing trend along with increasing number and size of polyps (P for trend<0.001). BMI, waist circumference (WC), fasting blood sugar, and triglyceride were higher in males with polyps than males in the control group. BMI and WC were higher and HDL-cholesterol was lower in females with polyps. The incidence of colorectal polyps was higher in male and female smokers (P<0.001 and P=0.035 respectively). CONCLUSIONS: Our results showed that older age, male gender, obesity, and smoking are risk factors for colorectal polyps. The prevalence of colorectal adenomatous polyps is 27.3% in <50 yrs, 33.4% in the 40s. For early detection and treatment, we recommend a screening colonoscopy for those with risk factors.

BACKGROUND: Prolonged extracorporeal circulation entails tremendous threats of red cell lysis, severe bleeding problems due to platelet injury and activation, and endothelial damages by sequestered leukocytes. In consideration of these problems, a new centrifugal pump was developed and tested clinically to evaluate its effectiveness. METHODS: We compared the effects of a centrifugal pump with those of a roller pump on hematological responses during cardiopulmonary bypass (CPB) in 20 coronary artery bypass surgery patients. The patients were divided into two groups of 10 each. The studied parameters included WBC counts, platelet counts, plasma Hb and D-dimer. Blood samples were taken after sternotomy, at 60 min, 120 min and 180 min after CPB start, and at 2 hr after CPB stop. RESULTS: No differences between the groups were found in bypass time, aortic cross clamp time, extracorporeal circulation flow and hematocrit. The centrifugal pump group demonstrated less platelet depletion (p<0.05), hemolysis (plasma Hb, p<0.05) and fibrinolysis (D-dimer, p<0.05). These differences were CPB time dependent and became statistically significant after 120 min bypass. CONCLUSION: We conclude that roller pump still can be safely used for standard cardiac procedures with bypass time less than 120 minutes and the centrifugal pump has significant potential to be safely applied to CPB for long ypass time in order to avoid postperfusion syndrome.

Multiple minute digitate hyperkeratosis (MMDH) is a rare disorder of keratinization characterized clinically by multiple, tiny, spiky, keratotic papules. Herein, we report a new case of MMDH. There was no family history of similar lesions or a personal history of underlying disease. The lesions were limited to the face and associated with acne vulgaris. We consider this case as a postinflammatory type of MMDH.

The purpose of this study was to elucidate the origin and cellular composition of retrocorneal membranes (RCMs) associated with chemical burns using immunohistochemical staining for primitive cell markers. Six cases of RCMs were collected during penetrating keratoplasty. We examined RCMs with hematoxylin and eosin (H&E), periodic acid-Schiff (PAS) staining and immunohistochemical analysis using monoclonal antibodies against hematopoietic stem cells (CD34, CD133, c-kit), mesenchymal stem cells (beta-1-integrin, TGF-beta, vimentin, hSTRO-1), fibroblasts (FGF-beta, alpha-smooth muscle actin), and corneal endothelial cells (type IV collagen, CD133, VEGF, VEGFR1). Histologic analysis of RCMs revealed an organized assembly of spindle-shaped cells, pigment-laden cells, and thin collagenous matrix structures. RCMs were positive for markers of mesenchymal stem cells including beta-1-integrin, TGF-beta, vimentin, and hSTRO-1. Fibroblast markers were also positive, including FGF-beta and alpha-smooth muscle actin (SMA). In contrast, immunohistochemical staining was negative for hematopoietic stem cell markers including CD34, CD133 and c-kit as well as corneal endothelial cell markers such as type IV collagen, CD133 except VEGF and VEGFR1. Pigment-laden cells did not stain with any antibodies. The results of this study suggest that RCMs consist of a thin collagen matrix and fibroblast-like cells and may be a possible neogenetic structure produced from a lineage of bone marrow-derived mesenchymal stem cells.
