INTRODUCTION Maffucci syndrome is a rare clinical entity (approximately 200 cases have been reported in the medical literature) with a combined occurrence of multiple enchondromas and vascular tumors. CASE PRESENTATION The case of a 43-year-old Japanese man with multiple chondromas and hemangiomas (Maffucci syndrome) is reported. One of the hemangiomas was removed and examined pathologically....

Synovial osteochondromatosis of the hip is a rare condition, and the surgical treatment approach for this condition requires complete removal of loose bodies combined with synovectomy. While these, procedures are generally accepted as the optimal treatment method, this is still controversial topic. Recent studies have reported that open surgical procedures remain acceptable for synovial osteoch...

Two experiments were conducted to compare a sample of calcium citrate-malate (CC-M) with a sample of commercial-grade limestone in starting broiler chick diets. In the first experiment, with 0.7 or 0.9% calcium from limestone or CC-M, no differences in bone development (dry fat-free tibia, tibia weight, tibia ash, or tibia calcium) were observed due to calcium source. However, chicks fed the di...

The effects of age vs. diet, potassium level, tetramethylthiuram disulfide (thiuram), and ionophores in the diet on the development of tibial dyschondroplasia in broilers was investigated. Changing broiler chicks from a diet that induced tibial dyschondroplasia to one that reduced the disease or vice versa caused a change in the incidence in the direction of the last-fed diet; however, in most ...

1314 deformity with mesomelic dwarfism of both upper and lower limbs. It is. the commonest variety of mesomelic dwarfism(3). Madelung deformity may also be seen associated with diverse disorders such as mucopolysaccharidosis, Turner's syndrome, achondroplasia, dyschondroplasia (Ollier's disease), multiple exostosis and multiple epiphyseal dysplasia. Madelung's original description of the lesion...

Defects in cartilage homeostasis can give rise to various skeletal disorders including osteochondromas. Osteochondromas are benign bone tumors caused by excess accumulation of chondrocytes, the main cell type of cartilage. The extracellular signal-regulated kinase (ERK) pathway is a major signaling node that functions within chondrocytes to regulate their growth and differentiation. However, it...

Synovial osteochondromatosis is a benign metaplasia of the synovium resulting in the formation of osteocartilaginous nodules within the synovial lining. At presentation, radiographs typically reveal these nodules to have broken free from the synovial lining, becoming loose bodies residing in the free space of the affected joint. These fragments readily receive the necessary nutrients for contin...

Several excellent reviews regarding nutrition and skeletal disorders have appeared in the last 20 yr. This review will cover several areas of vitamin D research, the area of feed deprivation, and bone abnormalities, because there has been considerable interest in these areas during the past 10 yr. Studies indicate that the quantitative requirement for cholecalciferol (D3) for broiler chickens i...
