Relationship between normal tension glaucoma and Flammer syndrome.

Background: Besides intraocular pressure, vascular factors play a role in the pathogenesis of glaucomatous optic neuropathy. One of these potential vascular factors is Flammer syndrome. The purpose of the present study was to determine in a Korean population whether signs and symptoms of Flammer syndrome occur more often in normal tension glaucoma patients than in control subjects.

Diagnosis of non-exudative (DRY) age related macular degeneration by non-invasive photon-correlation spectroscopy.

Purpose: Photon-correlation spectroscopy (PCS) (quasi-elastic light scattering spectroscopy, dynamic light scattering spectroscopy) allows the non-invasively reveal of local dynamics and local heterogeneities of macromolecular systems. The capability of this technique to diagnose the retinal pathologies by in-vivo investigations of spatial anomalies of retinas displaying non-exudative senile macular degeneration was evaluated. Further, the potential use of the technique for the diagnosis of the macular degeneration was analyzed and displayed by the Receiver Operating Curve (ROC).

The influence of various rehydration protocols on biomechanical properties of different acellular tissue matrices.

Objectives: This study evaluated the influence of different rehydration media and time periods on biomechanical and structural properties of different acellular collagen matrices (ACMs).

Materials And Methods: Specimens of three ACMs (mucoderm®, Mucograft®, Dynamatrix®) were rehydrated in saline solution (SS) or human blood for different time periods (5-60 min). ACMs under dry condition served as controls.

Influence of porcine-derived collagen matrix on endothelial progenitor cells: an in vitro study.

Porcine-derived collagen matrix (PDCM) has been reported as a promising alternative to autogenous soft tissue grafts in periodontal plastic surgery. The aim of this study was to analyze the influence of a novel PDCM on endothelial progenitor cells (EPC) in vitro. EPC were isolated from human peripheral blood, cultured and transferred on the PDCM (mucoderm®).

Treatment posibilities in ectromelia.

Introduction: Ectromelia is a congenital abnormality characterised by limb growth disturbances (aplasia or hypoplasia) during the period from 4th to 8th gestation week.

Case Outline: We present a case of hemimezomelic longitudinal ectromelia of the right upper limb associated with other skeletal abnormalities, surgically treated. An important role in the management of this case is attributed to the complex rehabilitation programme done before and after each surgical intervention.
