Dynamic ultrasound evaluation of body fillers and biostimulators in the buttocks of fresh-frozen specimen.

Background: Ultrasound imaging is a useful tool to study the injection of fillers and biostimulators in the body.

Objective: Sonographically evaluate real-time injections of fillers and biostimulators and describe their behavior in the subcutaneous tissue of the buttocks of fresh-frozen specimen.

Methods: injection of two brands of high-density hyaluronic acid (HA), one brand of calcium hydroxyapatite (CaHA), one brand of hybrid injectable (CaHa + HA), one brand of polycaprolactone (PCL) and three brands of poly-l-lactic acid (PLLA) were performed in the subcutaneous tissue of the gluteal region under ultrasonography visualization on a fresh-frozen specimen.

Lenalidomide in the management of eosinophilic dermatosis of hematological malignancy.

Eosinophilic dermatosis of hematological malignancy is a paraneoplastic skin eruption associated with chronic lymphocytic leukemia and other B-cell malignancies. It clinically resembles an insect bite reaction and it can precede the symptoms of the hematological malignancy or be related to a more aggressive course. Different treatments have been proposed, but partial response and recurrence are frequent.

αEβ7 Expression Increases With the Extent of Cutaneous Involvement in Mycosis Fungoides.

Background: Cell adhesion molecules are essential to lymphocyte migration in neoplastic and inflammatory skin diseases. Our aim was to investigate possible differences in cell adhesion molecule expression between mycosis fungoides (MF) and inflammatory skin diseases (drug reactions and allergic contact dermatitis).

Methods: We selected 33 biopsies from patients with MF and 10 biopsies of patients with inflammatory skin diseases from Department of Pathology-Universidade Federal de São Paulo (UNIFESP) from January 1997 to December 2013.

Limitations of DNA sequencing for diagnosis of a mixed infection by two fungi, Phaeoacremonium venezuelense and a Plectophomella sp., in a transplant recipient.

We describe a rare case of a subcutaneous infection by both Phaeoacremonium venezuelense and Plectophomella sp. in a Brazilian male. Sequencing of a beta-tubulin gene fragment allowed us to confirm the identification of the former.
