intramuscular cavernous hemangiomas represent less than 1% of all hemangiomas. typical presentation is a soft-tissue mass and/or pain without cutaneous changes. whereas calcification of hemangiomas is common; ossification of these lesions is very rare. we describe a case of ossified intramuscular hemangioma of quadriceps presented with painless knee extension contracture and thigh mass.

Skeletal animation is a concept that has been used in the areas of motion pictures and computer games to create realistic motion for the animation of articulated characters. Recent work has applied skeletal animation techniques from inverse kinematics to the field of graph interaction. The previous work introduced an interesting idea suggesting a skeletal graph interaction system would be intui...

Glucocorticoid-induced osteoporosis is the most frequently occurring type of secondary osteoporosis. Antagonists of β-adrenergic receptors are now considered to be potential drugs under investigation for osteoporosis. The aim of the present study was to investigate the effects of propranolol, a nonselective β-receptor antagonist, on the skeletal system of mature male rats and on the development...

incontinentia pigmenti (ip) is an x-linked dominant genodermatosis characterized by typical skin lesions along blaschko's lines and associated with ocular, dental, nails, hair, skeletal, central nervous system and cardiovascular anomalies. we report a 5-year-old boy with cutaneous hyperpigmentation along blaschko's lines, atrophic streaks, strabismus and mental retardation. he showed the charac...

parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (phpt). skeletal system is significantly affected by phpt. brown tumors are known to have affinity for 99mtc-mibi. we report a rare case of phpt presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99mtc-pertechnetate/9...

Case report. A 56-year-old woman was being treated for dryness of her skin, prunitus and attacks of flushing. She was noted to have marked cyanosis of her hands and feet. Routine investigations revealed that she was in mild renal failure and an intravenous urogram showed multiple sclerotic bone lesions in the lumbar spine and right femoral neck (Figs 1 and 2). A skin biopsy stained with Giemsa,...

It has become clear that complex interactions underlie the relationship between the skeletal and immune systems. This is particularly true for the development of immune cells in the bone marrow as well as the functions of bone cells in skeletal homeostasis and pathologies. Because these two disciplines developed independently, investigators with an interest in either often do not fully apprecia...

Aging is an inevitable biological process that is characterized by a general decline in the physiological and biochemical functions of the major systems. In the case of the neuromuscular system, reductions in strength and mobility cause a deterioration in motor performance, impaired mobility and disability. At the cellular level, aging is caused by a progressive decline in mitochondrial functio...

Two different proliferation assays have been used to measure the proliferative Potential of IgG-fractions from 57 patients with nontoxic goiter of an iodine-deficient area: primary human thyroid epithelial cells (TEC) and the thouroughly investigated FRTL-5 cell line. IgGfractions from patients with nontoxic goiter (n = 30), nontoxic recurrent goiter (n = 8), toxicnodular goiter (n = 15) and Ca...
