Extra-capsular synovial chondroma is a rare condition in which metaplastic cartilaginous mass is formed by the cartilage nodule within the synovial connective tissue break through the joint capsule and continue to proliferate. The authors have experienced a case of giant extracapsular synovial chondroma, affecting the knee joint of 54 years old woman. A case of giant extra-capsular synovial chondroma is reported with brief review of literature.

The origins of medullary carcinoma and papillary carcinoma of thyroid are embryologically different. We report a case of simultaneous occurrence of medullary carcinoma and papillary carcinoma of the thyroid in the same thyroid gland. In this case, the occurrence of the two tumors may be a coincidence, does not have embryological or genetical significance.

Although the operation for the ventral lesion of craniovrtebral junction and atlantoaxial area is considered difficult to perform, the transoral approach made it safer and easier. The authors report 10 cases(9 patients) treated by the transoral approach for the lesion of craniovertebral junction over the past 13 years at the Ajou University Hospital and the Presbyterian Medical Center. Of these 10 cases, there were 4 odontoid type II fractures, 1 atlantoaxial dislocation, 1 os odontoideum, 1 chordoma at lower clival area, 1 rheumatoid arthritis, 1 epidural abscess and 1 wound revision due to slippage of grafted bone after clivoaxial fusion. The surgical methods included 4 cases of anterior decompression and clivoaxial fusion, 2 cases of anterior decompression and C1-2 interarticular joint fusion, 1 case of anterior decompression and clivoaxial fusion followed by posterior fusion, and 3 cases of anterior decompression and posterior fusion. In nonreducible atlantoaxial dislocation or ventral cord compression le sion, if the clivoaxial angle was less than 120 degree, the transoral approach was selected. The appropriate surgical approach must be selected according to the degree of compression of the neural tissue involving the craniovertebral junction and atlantoaxial dislocation.

Background : Recurrent wheezing in infants is manifested in a number of disease spectrums and gastroesophageal reflux ( GER ) has been known to be associated with apnea, recurrent pneumonia, asthma, chronic cough, and wheezing. The prevalence of GER in infants with recurrent wheezing and the relationship between atopy and GER in infantile asthmatics have not yet been established, but it was hypothesized that microaspiration of food allergen could induce food-induced wheezing. Objective : To evaluate the prevalence of GER in infants with recurrent wheezing episodes, and to determine whether the presence of atopy affects the prevalence of GER in infantile asthmatics. Method : Seventy infants with recurrent wheezing episodes were evaluated for GER using 24 hour continuous esophageal pH monitoring. Patients were classified into five groups, : 12 atopic asthmatics : 20 nonatopic asthmatics : 15 infants with recurrent bronchiolitis : 8 infants with recurrent pneumonia : and 15 infants with chronic lung disease ( CLD ) of prematurity. GER was considered to be prevalent when reflux index was higher than 95 percentile of normal values by Vandenplas, 1991. Result : The prevalence of GER in infants with recurrent wheezing was 21.4%. The prevalence of GER in each group was 25% in atopic asthmatics, 20% in nonatopic asthmatics, 6.7% in infants with recurrent bronchiolitis, 12.5% in infants with recurrent pneumonia, and 40% in infants with CLD of prematurity. There were no significant differences in prevalence of GER between atopic asthmatics and nonatopic asthmatics, between asthmatics with atopic dermatitis and those without, and between asthmatics with family history of allergy and those without. CONCLUSION: The prevalence of GER in infants with recurrent wheezing was high, especially in infantile asthmatics and infants with chronic lung disease of prematurity. The presence of atopy may not affect the prevalence of GER in infantile asthmatics.

STUDY DESIGN: We analyzed the segmental mobility of the lumbar spine after anterior stabilization in the thoracolumbar spinal fractures, and the data were compared with those obtained from an asymptomatic control group. OBJECTIVE: To determine the effects of anterior stabilization on the unfused segments of the lumbar spine. SUMMARY OF LITERATURE REVIEW: Spinal fusions are commenly used to stabilize unstable motion segments and to help the maintenance of correction afforded by the instrumentation applied in surgery for spinal deformity or injuries. How the presence of the fusion effects upon the remaining infused spine is not well understood. MATERIALS AND METHODS: We measured the segmental deformations of the lumbar spine radiologically, from maximum flexion to maximum extension, right and left maximum lateral bending, in 20 asymptomatic volunteers( the control group ) and 30 patients who had the anterior stabilization of the thoracolumbar spinal fractures(the study group). We assessed the percentage of segmental deformations which were obtained by multipling one hundred after the segmental deformation value was divided by the total lumbar deformation value. We made the comparison between the White and Panjabi's results and the control group, between the control group and the study group, between the segmental deformations and the percentage of segmental deformations. RESULTS: In the control group , the segmental deformations were smaller than those of the corresponding segmenus in the White and Panjabi's results. In the flexion-extension rotation of the lumbarspine, the segmental deformations had a tendency to increase from cephalad to caudal in the controland study group. In the residual lumbar spinal mobility, the segmental deformations of the study group had decreased rather than those of the control group. Especially the segmental deformation below the juxtafused segment had increased more than those of the corresponding segment of the control group in the right lateral bending rotation. The residual lumbar spinal mobility tended to decrease from T12 vertebral stabilization to L2 vertebral stabilization. CONCLUSION: The unfused segments had accommodated a greater percentage of segmental deformations in spite of diminishing the segmental deformations in comparison with those of the corresponding control subjects. It suggests that the greater percentage of segmental deformations predisposes to early degeneration of unfused segments.
