Changes in portal hypertensive gastropathy after endoscopic variceal band ligation and correlation with serum nitric oxide level

We studied 20 patients with Liver Cirrhosis and Portal Hypertension. The aim of the work was to access the impact of endoscopic variceal band ligation on changes in portal hypertensive gastropathy, and to correlate changes with changes in nitric oxide level. Significant improvement in the mucosal wall thickness, number of vessels, total vascular area despite non significant variation in nitric oxide level

Cutaneous changes in diabetic foot lesion: clinicopathological study and ultrastructural changes in peripheral nerves

Forty five diabetic patients were submitted to this study. They were allocated into 2 groups: Group A comprised 30 patients with diabetic foot lesion [DFL], and group B included 15 diabetic patients without DFL as a control group. A skin biopsy from the edge of the lesion in group A and from medial border of the foot in group B were obtained. There was no significant difference between the incidence of hyperkeratosis, thick collagen, nerve lesion or vascular lesion in group A cases. However, there was high significant difference between group A and B in the incidence of cutaneous changes. Consequently, cases of group B with hyperkeratosis, thick collagen, neuropathy and vascular lesion would be considered at risk to develop DFL
