Aggressive angiomyxoma to 57-year old man.

Aggressive angiomyxoma is a rare mesenchymal tumor occurring usually in women of reproductive age in pelvic-perineum region. These myofibroblastic tumors rarely affect men and non-pelvic-perineum anatomical sites. There are few literature references for aggressive angiomyxoma in men.

Articular cartilage generation applying PEG-LA-DM/PEGDM copolymer hydrogels.

Background: Injuries to the human native cartilage tissue are particularly problematic because cartilage has little to no ability to heal or regenerate itself. Employing a tissue engineering strategy that combines suitable cell sources and biomimetic hydrogels could be a promising alternative to achieve cartilage regeneration. However, the weak mechanical properties may be the major drawback to use fully degradable hydrogels.

Injectable and photopolymerizable tissue-engineered auricular cartilage using poly(ethylene glycol) dimethacrylate copolymer hydrogels.

In this study we investigated the histological, biochemical, and integrative features of the neocartilage using swine auricular chondrocytes photoencapsulated into two poly(ethylene glycol) dimethacrylate (PEGDM) copolymer hydrogels of a different degradation profile: degradable (PEG-4,5LA-DM) and nondegradable (PEGDM) macromers in molar ratios of 60:40 and 70:30. Integration of the engineered tissue with existing native cartilage was examined using an articular cartilaginous ring model. Experimental group samples (total n=96) were implanted subcutaneously into nude mice and harvested at 6, 12, and 18 weeks.

Brucella cervical spondylitis complicated by spinal cord compression: a case report.

A case of 65-year-old farmer who presented with Brucella-related cervical spondylitis is described. Because of the advanced form of the infection resulted in neurological impairment, cervical vertebra corpectomy and debridement of the paravertebral granulomatous tissue deposits were performed followed by stabilization with anterior plating and bone grafting. In addition, double antimicrobial chemotherapy regimen was administered for 12 weeks.

Histomorphologic study of discoid meniscus.

Purpose: The purpose of this study was to investigate the matrix collagen network of the discoid lateral meniscus in comparison with normal lateral meniscus.

Methods: Discoid meniscus samples obtained arthroscopically from 10 patients with a diagnosis of intact complete-type discoid lateral meniscus by a technique of excision in 1 piece were examined histomorphologically regarding the integrity of both main collagen fiber systems, radial and circular, because they have been described in the structure of normal knee meniscus. As a control group, intact lateral menisci excised during knee arthroplasty procedures were used.

Engineering cartilage in a photochemically crosslinked collagen gel.

This study's purpose was to investigate whether photochemically crosslinking collagen gel to encapsulate chondrocytes (articular, auricular, costal) would permit new cartilage formation in vivo, and to determine whether this neocartilage had the ability to integrate with existing native cartilage. Chondrocytes from swine were embedded in collagen gel that was photochemically crosslinked using riboflavin and visible light. Controls were collagen gels containing cells that were not crosslinked.

Epidemiologic, clinical and arthroscopic study of the discoid meniscus variant in Greek population.

This retrospective study was aimed to investigate the epidemiologic, clinical and arthroscopic features of discoid meniscus variant in Greek population. We reviewed the cases of 2,132 patients who underwent knee arthroscopy between 1986 and 2004 and diagnosis of discoid lateral meniscus was established in 39 patients with mean age of 31.7 +/- 9.
