Association of colon adenomas and skin tags: coincidence or coexistence?
Findings of the present study may show a co-existence of colonic polyps and ST. Although previous studies have indicated that insulin resistance may play a role in the pathogenesis of both lesions in diabetic and obese patients, we found no indication of a relationship in nondiabetic and nonobese patients with increased levels of EGF in patients with ST, suggesting an alternative pathogenesis in this patient group.
Our findings demonstrate that arginine metabolism by arginase promotes fibrosis of muscle in muscular dystrophy and contributes to kyphosis. Our findings also show that long-term, dietary supplementation with arginine exacerbates fibrosis of dystrophic heart and muscles. Thus, commonly-practiced dietary supplementation with arginine by DMD patients has potential risk for increasing pathology when performed for long periods, despite reports of benefits acquired with short-term supplementation.
