Dysplasia epiphysealis multiplex is a rare syndrome, first discribed by Fairbank in 1935, but numerous publications have made it a well-recognized entity. The syndrome is caused by a congenital developmental error of unknown etiology, characterized by changes in the developing epiphyses, dwarfism and stubby digits in children of normal intelligence. Diagnosis is mainly by roentgenographic apperences of the epiphyses before fusion to the shaft. The centers of ossification of the epiphyses are late in appearing, slow in developing, deformed in shape and irregular in density. The spine is never affected, blood and biochemicaI studies show no abnormality. A case of dysplasia epiphysealis multiplex which revealed typical roentgenographic pictures is presented with a brief review of a literature.

Bone grafts are used in the repair of segmental bone loss caused by severe trauma, bone tumors and infection, and to enhance bone healing in ununited fractures. Autograft is the most frequently used and the most effective method, but because of inadquate supply and additional operative morbidity, allograft or heterograft could be used. Heterograft has been shown to be poorly tolerated by the host and ineffective in providing an osteogenic system. The objective of this study is to observe healing process of a segmental defect of long bone following to heterograft, and to compare the difference of histologic process between autograft and hetero graft. Twenty-four white rabbits weighing 1,000 to 2,000 grams were used for the experiment. A segment measuring three times the diameter of the ulna shaft (1.5 to 2cm) of rabbit was resected with its periosteum. Twenty-four white rabbit were divided into three groups (control, autograft, heterograft group) according to graft methods, each group comprising of eight rabbits. The animals were sacrificed at 2, 4, 8 and 12 weeks after the experimental procedures and were periodically evaluated by radiographs and histology. The obtained results were as follows: 1. The results of the radiological evaluation showed that no ungrafted ulnar defects (control group) healed. In the heterograft group, partial union was observed from 8 weeks and complete union was obtained on 12 weeks. In the autograft group, partial union was observed on 2 weeks and complete union was obtained on 4 weeks. 2. The results from histological examination showed that the ungrafted ulnae did not heal across the defect but some immature trabeculae were founded on the edges of the defect. In the heterograft group, immature trabeculae were appeared from 4 weeks and defects were substituted with mature trabeculae on 12 weeks. In autograft group, defects were substituted with immature trabeculae on 2 weeks and with mature trabeculae on 4 weeks. As seen in the results of the experiment, union could be obtained with the heterograft, but needed more long time than autograft. Though the autograft is the most effective graft method in bone defect or non-union, above results suggest the heterograft as the alternative method in the treatment of large bone defect, in a multioperated patient, or in the children or the elderly, combined with autograft or alone.

Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.

Enlargement of the extraocular muscles may cause diplopia and exophthalmos. The most common cause of the exophthalmos is thyroid associated ophthalmopathy(TAO), followed by inflammatory diseases and orbital tumors. TAO has the classical features of proptosis and lid retraction. However, the diagnosis is frequently confused with other eye diseases due to various symptoms and signs. Therefore, measurement of the size of extraocular muscles in both normal and TAO patients will make diagnosis and treatment plan easier in TAO and other muscular diseases of the orbit. For the clinical application, we measured the size of muscle with and without magnification and the results were compared. Normal mean values of cross sectional length and thickness of the extraocular muscles measured by CT scan showed 8.83x 3.60 in the inferior rectus, 9.20x3.20 in the superior muscle group, 9.45x 3.48 in the medial rectus and 9.65x3.23 mm in the lateral rectus muscle with no sex differences. All four muscles showed statistically significant enlargement in TAO and the thickness showed greater increase than the length. Superior muscle group(superior rectus and levator muscle)was the most frequently involved in TAO in both sexes. There was no significant statistical difference in the methods of measurement.
