[Rosacea-like demodicidosis and chronic blepharitis].

Demodicidosis is a parasitic skin disease caused by the follicle mites Demodex sp. In this article, we present a case of rosacea-like demodicidosis, discuss the clinical features of Demodex infestation in man and review their diagnosis and therapeutic modalities. A 37-year-old woman presented in our department with chronic blepharitis present for one year.

Immunohistochemical analysis of vascular endothelial growth factor (VEGF) and p53 expression in pterygium from Tunisian patients.

A pterygium is characterized by abnormal fibrovascular corneoconjunctival tissue. A number of investigations have attempted to elucidate this incompletely understood pathology. Since vascular endothelial growth factor (VEGF) and p53 are known to participate in tumor vascularization, our purpose was to study VEGF and p53 expression in active primary and recurrent pterygium from Tunisian patients.

Immunohistochemical analysis of cellular adhesion molecules (ICAM-1, VCAM-1) and VEGF in fibrovascular membranes of patients with proliferative diabetic retinopathy: preliminary study.

Purpose: Diabetic fibrovascular membranes are the main pathological changes of proliferative diabetic retinopathy that can cause serious complications leading to blindness. Since the mechanism of fibrovascular membrane development is still unknown, the aim of our study was to identify potential biomarkers for this pathology. To this end, we analyzed the simultaneous expression of ICAM-1, VCAM-1 and VEGF within tissues of diabetic fibrovascular membranes.

[Drusen in children: three case studies].

We report three cases of optic disc drusen in children. The children were 5 months, 10 years, and 11 years old. Two of them were male.

[Expression of Bax and Bcl-2 apoptotic factors in the conjunctiva of diabetic patients: a preliminary study].

Introduction: Apoptosis, or programmed cell death, is necessary to multicellular organism survival, in contrast to involuntary necrosis that is devastating for tissue. It is positively or negatively regulated by proteins of the Bcl-2 family. The aim of our study was to analyze the expression of apoptotic factors Bax and Bcl-2 in the bulbar conjunctiva of diabetic patients without retinopathy and to compare it to the expression of these factors in nondiabetic patients.
