[Allergic contact dermatitis to cosmetics].

Introduction: Contact dermatitis to cosmetics is a common problem in the general population, although its prevalence appears to be underestimated. We reviewed cases of allergic contact dermatitis to cosmetics diagnosed in our dermatology department over a 7-year period with a view to identifying the allergens responsible, the frequency of occurrence of these allergens, and the cosmetic products implicated.

Methods: Using the database of the skin allergy department, we undertook a search of all cases of allergic contact dermatitis to cosmetics diagnosed in our department from January 2000 through October 2007.

[Chronic cutaneous fistula secondary to mandibular osteomyelitis].

Cutaneous fistulas and sinuses in the maxillofacial region secondary to osteomyelitis rarely appear in clinical practice. The most frequent cause of mandibular osteomyelitis is a dental infection, but it may also be hematogenic in origin. The diagnostic criteria for bacterial osteomyelitis are suppuration and osteolytic changes in the radiological study.
