Antibiotic-resistant Propionibacterium acnes on the skin of patients with moderate to severe acne in Stockholm.

The objective was to study the prevalence and antibiotic susceptibility patterns of Propionibacterium acnes strains isolated from patients with moderate to severe acne in Stockholm, Sweden and to determine the diversity of pulsed-field gel electrophoresis types among resistant P. acnes strains. One hundred antibiotic-treated patients and 30 non-antibiotic-treated patients with moderate to severe acne participated in the investigation.

Malassezia furfur in infantile seborrheic dermatitis.

Malassezia furfur is important in the pathogenesis of a number of dermatologic diseases including seborrheic dermatitis in adults. It has also recently been suggested that M. furfur might be the etiologic agent in infantile seborrheic dermatitis (ISD).

Potentiometric and voltammetric detection using a two-channel fountain cell.

The design and use of a two-channel fountain cell in potentiometric and voltammetric detection is described. The two flows produced two distinct sectors inside the thin layer region and one of the sectors was used as the internal electrolyte of a reference electrode built into the cell body and the other as the indicator/counter electrode section. The behavior of the flowthrough Ag/AgCl reference electrode was first investigated and found satisfactory and it was then employed as the reference electrode in the subsequent experiments.
