Acne characteristics in Latin American patients and the potential role of trifarotene.

Background: Individualization of treatment based on acne type and severity, location, disease burden, and patient preference is required to maximize efficacy, safety, and adherence to therapy. Latin American populations have unique attributes that must be considered as part of this process to improve clinical success and achieve patient goals. Acne is more common among patients with darker skin phototypes, in whom it is often associated with postinflammatory hyperpigmentation and scarring-the most important acne sequelae-potentially due to more frequent and more severe underlying inflammatory processes in this population.

Clinical and histological comparative outcomes after injections of poly-L-lactic acid and calcium hydroxyapatite in arms: A split side study.

Background: Although much has been published on the use of poly-L-lactic acid (PLLA) and calcium hydroxyapatite (CaHA) for off-face indications, questions remain regarding their exact mechanisms of action in subcutaneous tissue and their comparative efficacy.

Objective: To present the clinical and histological results of the PLLA and CaHA injections into the opposing arms of the same patients.

Methods: Five women received superficial subcutaneous injections of PLLA into the left arm and CaHA into the right arm.

Comparative study of the prevalence of sepsis in patients admitted to dermatology and internal medicine wards.

Background: Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis.

Do you know this syndrome?

Goldenhar syndrome is a sporadic or inherited genetic syndrome characterized by limbal dermoids, preauricular skin tags and mandibular hypoplasia. Vertebral abnormalities may occur. The incidence of this syndrome ranges from 1 in 5,600 to 1 in >20,000 live births.

Rheumatoid nodules: evaluation of the therapeutic response to intralesional fluorouracil and triamcinolone.

Rheumatoid nodules are the most common extra-articular manifestation of rheumatoid arthritis and are present in around 20-25% of patients. Their etiology is unknown and although the nodules may undergo spontaneous remission during the treatment of rheumatoid arthritis, they usually constitute a therapeutic challenge. The present paper describes a case in which the response of rheumatoid nodules was evaluated by ultrasound following infiltration of triamcinolone acetonide and 5-fluorouracil.

Hematidrosis: a case report and review of the literature.

The authors report the case of a 9 year-old female who had bleeding episodes around the mouth after strenuous exercise or prolonged exposure to heat. Characteristically, bleeding occurred right after sweat drops started appearing on the surface of the skin around the mouth. The bleeding episodes ceased spontaneously.
