Primary cerebral myxofibrosarcoma: clinical, morphologic, immunohistochemical, molecular, and ultrastructural study of an infrequent tumor in an extraordinary localization.

Herein, we describe an intracerebral primary low-grade myxofibrosarcoma occurring in a 9-year-old boy. The lesion measured 7 cm and occupied the left parieto-occipital region. A gross-total removal of the tumor was performed.

Methodological models for in vitro amplification and maintenance of human articular chondrocytes from elderly patients.

Articular cartilage defects, an exceedingly common problem closely correlated with advancing age, is characterized by lack of spontaneous resolution because of the limited regenerative capacity of adult articular chondrocytes. Medical and surgical therapies yield unsatisfactory short-lasting results. Recently, cultured autologous chondrocytes have been proposed as a source to promote repair of deep cartilage defects.

Scanning electron microscopic analysis of acrylic intraocular lenses for microincision cataract surgery.

Purpose: To analyze the surface quality before and after folding of 2 intraocular lens (IOL) models designed for microincision cataract surgery.

Setting: Eye Clinic and Department of Human Pathology and Oncology, University of Florence, Florence, Italy.

Methods: Two IOL models now available for sub-2.

Folding procedure for acrylic intraocular lenses.

Purpose: To compare in vitro the effect of 2 standard methods of folding acrylic intraocular lenses (IOLs) on surface characteristics and bacterial adhesion.

Setting: Eye Clinic and Department of Health-Microbiology Unit, University of Florence, Florence, Italy.

Methods: To evaluate the effect of folding, 2 types of acrylic IOLs were not folded or folded with a forceps or an injector and then processed for scanning electron microscopy (SEM) examination.
