Antibacterial Susceptibility Testing of in Acne Vulgaris Patients.

Introduction: Combination therapy is widely used for the treatment of acne vulgaris (AV), including local anti-inflammatory drugs containing antimicrobials, such as clindamycin or erythromycin, to inhibit () growth and at the same time reduce the production of inflammatory mediators. The aim of the study is to compare the antibacterial susceptibility of to clindamycin and erythromycin in AV patients compared with healthy patients in the control group (CG).

Methods: The prospective study included 56 patients with clinically diagnosed AV symptoms and 12 patients were included in the CG who did not have AV.

Rubeosis faciei diabeticorum is not associated with oxidative stress and skin autofluorescence.

Background: Rubeosis faciei diabeticorum is a persistent facial erythema in patients with diabetes mellitus. The actual pathogenesis has not been studied. However, it is speculated to be a cutaneous diabetic microangiopathy.

Comparison of single-spot technique and RGB imaging for erythema index estimation.

A commercially available point measurement device, the Mexameter(®), and an experimental RGB imaging prototype device were used for erythema index estimation of 50 rosacea patients by analysing the level of skin redness on the forehead, both cheeks and both sides of a nose. Results are compared with Clinician's Erythema Assessment (CEA) values given by two dermatologists. The Mexameter uses 568 nm and 660 nm LEDs and a photodetector for estimation of erythema index, while the used prototype device acquired RGB images at 460 nm, 530 nm and 665 nm LED illumination.
