[Resistance to vitamin K antagonist revealing interaction with soy lecithin].

Vitamin K antagonists (VKA) are difficult to use because of a narrow therapeutic index and of a marked inter- and intra-individual variability among patients in the required dosage. This drug may interact with many other drugs and same with certain food compounds. We report the case of potential interaction between soy lecithin and Vitamin K antagonists in a 46 years-old woman.

Molecular Identification of Malassezia Species in Patients with Malassezia folliculitis in Sfax, Tunisia.

Aim: Malassezia folliculitis is caused by the invasion of hair follicles by large numbers of Malassezia cells. Several Malassezia researches still use cultures, morphology and biochemical techniques. The aim of this study was to identify Malassezia species isolated from patients diagnosed with folliculitis, at the Parasitology and Mycology Laboratory of Sfax University Hospital, and to explore the genetic diversity of Malassezia by using PCR-RFLP and PCR-sequencing targeting the rDNA region of the Malassezia genome.
