11/42. Skeletal and dental fluorosis: two case reports.Two case reports from a high fluoride (10 ppm) rural community. They presented with severe degrees of dental fluorosis, hyper-sensitivity of teeth and skeletal fluorosis all arising from the ingestion of high amount of fluoride in water over a long period of time. Both cases had deformities of the upper and lower limbs. However, the deformities were more pronounced in the lower limbs than in the upper limbs, resulting in knock knee. Radiological finding showed osteosclerosis of the axial bones while the appendicular bones exhibited osteoporosis. There was marked change of bone structure observed as osteomalacia, and course trabecular bone pattern. osteoporosis was also associated with cortical thinning. Periosteal bone apposition was observed in the bones: and genu valgum of the limbs. Biochemical tests revealed normal values for serum calcium and inorganic phosphate. However, the serum alkaline phosphatase was elevated. This may be an indication of a pathological condition where there are possible compensatory mechanisms to maintain normal levels of serum calcium and inorganic phosphate. One case which had undergone corrective surgical intervention of the lower limbs four years earlier, had continued to live in the same environment using drinking water with 10 ppmF after corrective surgery, and showed no improvement.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
12/42. Digital subtraction angiography in musculoskeletal tumors and other conditions.One hundred and forty consecutive DSA examinations of various musculoskeletal diseases were analyzed with respect to the contributions and/or limits of this modern diagnostic imaging modality. angiography remains the imaging tool of choice for many benign and malignant orthopedic conditions of bones and soft tissues, mainly when MRI is still not generally available. It remains indispensable for embolization and/or local chemotherapy. DSA has the advantage of being less invasive and it also surpasses analog arteriography in better visualization of vascular patterns hidden in hyperostosis, sclerosis, and metallic shadows. Angiographic investigations, when necessary, should therefore start with DSA.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
13/42. Case report 594: Osseous sarcoidosis (osteolytic) of lumbar spine and pelvis.A case of destructive osseous sarcoidosis involving the lower lumbar spine, sacrum, and pelvis has been presented. The pattern of multiple small lytic lesions without sclerosis in this distribution has not been described previously. Identification of these lesions was only possible by computed tomography and differentiation from metastatic disease required open biopsy.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
14/42. Total osteolysis of the mandibular condyle in progressive systemic sclerosis.This report calls attention to the complete resorption of the mandibular condyle in progressive systemic sclerosis (scleroderma), a previously unreported finding. This was associated with osteolysis of the ipsilateral coronoid process, both mandibular angles, and autoamputation of the fingertips. The Panorex provides a simple, effective method for studying the mandible in systemic sclerosis. Similar mandibular osteolysis with vinyl chloride exposure is noted.- - - - - - - - - - ranking = 6keywords = sclerosis (Clic here for more details about this article) |
15/42. Lymphographic patterns in systemic mastocytosis with diffuse bone involvement and hematological signs.lymphography revealed the nature of diffuse lymph node involvement in systemic mastocytosis with diffuse bone involvement and hematological signs, similar to that seen in some malignant hematological diseases or in osteomyelosclerosis. The final stages of transformation into acute lymphoblastic leukemia must also be considered.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
16/42. plasma cell sclerosis of bone: a spectrum of disease.We describe the clinical, radiographic, and pathologic manifestations of a group of disorders characterized by osteosclerosis in association with plasmacytic infiltration of bone marrow. These conditions include multiple myeloma, plasma cell granuloma, sternocostoclavicular hyperostosis, the poems syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes), and chronic symmetric plasma cell osteomyelitis of childhood. Although clinically unrelated in many respects, features shared by these diseases support the existence of a specific factor linking the plasma cell to local osteogenesis.- - - - - - - - - - ranking = 5keywords = sclerosis (Clic here for more details about this article) |
17/42. Osteopathia striata, cranial sclerosis with cleft palate and facial nerve palsy.Osteopathia striata (OS) is a rare bone dysplasia characterized by longitudinal sclerotic striations of the long bones. It is of no clinical importance, but OS associated with cranial sclerosis represents a separate entity with a high incidence of palatine malformations and deafness. Only 19 cases of this entity have been reported in the literature. One patient of this series also had facial nerve paralysis. This paper presents a second case of OS, cranial sclerosis, palatine pathology and recurrent facial nerve paralysis. This incidence of 2/20 (10%) does not seem to be coincidental but raises the possibility that facial nerve palsy is one of the clinical manifestations of this specific bone abnormality.- - - - - - - - - - ranking = 6keywords = sclerosis (Clic here for more details about this article) |
18/42. erdheim-chester disease. Case report and review of the literature.erdheim-chester disease is a distinctive pathologic and radiographic entity characterized by bilateral, symmetric sclerosis of the metaphyseal regions of long bones and infiltration of foamy, lipid-laden histiocytes. Clinically, it ranges from an asymptomatic, focal process to a fatal, systemic disease. All previously reported cases of erdheim-chester disease are reviewed and a new case with diabetes insipidus, partial hypopituitarism, histiocytic skin lesions, and retro-orbital tumors is presented. An 11-year follow-up reveals progression from a benign, limited process to a progressive, systemic disease. patients with erdheim-chester disease show markedly disparate clinical courses and some features similar to hand-Schuller-Christian disease. They need careful monitoring and further attempts at treatment.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
19/42. Sternocostoclavicular hyperostosis. A case report and review of the literature.Sternocostoclavicular hyperostosis (SCCH) or intersternocostoclavicular ossification is a recently recognized disorder of unknown origin. SCCH is characterized by painful, condensing hypertrophy of the sternum, both clavicles, and the upper ribs. Since its original description by Sonozaki in 1974, approximately 40 cases have been reported, mainly in the Japanese literature. This peculiar hyperostotic syndrome is often misdiagnosed. The differentiation from osteitis deformans can be difficult. Clinically, the disease produces a swelling in the upper chest area with persistent, pulling pain exacerbated by cold and dampness. The condition is a nonspecific inflammatory syndrome. Radiographs usually show symmetric hyperostosis of the sternal portions of the clavicles, synostosis of the sternoclavicular joints, a thickened sternum, and varying degrees of involvement of the upper ribs and intercostoclavicular space. biopsy specimens reveal hyperostotic sclerosis of the cancellous bone. Although the cause of the syndrome is unknown, clinical, radiologic, and histologic findings indicate that it represents a distinct entity. The treatment of SCCH remains symptomatic.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
20/42. Skeletal complications of gaucher disease.gaucher disease is a collection of related disorders of sphingolipid catabolism caused by the deficiency of a specific beta-glucosidase. The inefficiency of this enzyme, glucocerebrosidase, to degrade its natural substrate leads to the accumulation of the complex lipid glucocerebroside in tissue macrophages. The pathogenesis of the disease is, as yet, poorly understood. The manifestations of the disease are protean with hepatosplenomegaly and bone deterioration frequently the predominating signs. The disease most frequently causes disability because of its effects on the skeleton. This review seeks to summarize the current clinical understanding of these complications. Experience with 327 patients reveals that the bone disease in this disorder is extremely variable. The severity of the problems range from asymptomatic persons with neither radiographic, scintigraphic, nor histologic evidence of bone involvement to those whose skeleton is completely devastated by a process of osteopenia, osteonecrosis, and osteosclerosis. These severely affected individuals show the most bizarre deformities in their bones and are subject to pathologic fracture. Most patients fortunately, are less profoundly affected, but many are plagued by bone pain of an arthritic nature or by an acute prostrating bone crisis probably best described as a bone infarction. The accepted etiology that these crises are a result of vascular compromise produced by occlusion of vessels by Gaucher cells is not supported by scintigraphic or histologic studies. Moreover, the vascular hypothesis does not explain the variety of lesions of the skeleton seen in this multifocal bone disease. Preliminary metabolic and endocrinologic studies suggest that this is not a systemic disorder of metabolism which affects bone uniformly. On the contrary, the lesions are multiple and localized, and sometimes much of the skeleton is preserved. These observations suggest that bone is affected because of collections of Gaucher cells scattered throughout its substance and may be the result of a toxic process around these foci. Alternatively, the storage of glucocerebroside in tissue macrophages may disturb the generation of competent osteoclasts and thus result in a failure to maintain a healthy skeleton. Further research is needed to delineate the pathogenesis of this disorder before any effective therapy can be developed.- - - - - - - - - - ranking = 1keywords = sclerosis (Clic here for more details about this article) |
