Mixed tumor that occurs in the orbit is very rare but takes a great part of the tumors of the lacrimal glands. It is so pleomorphic that a great deal of confusion exists as to the nature and histogenesis. The tumor appears as a palpable mass in the upper and outer quadrant of the orbit. Usually the tumor is hard, nodular and slightly mobile, lying just underneath the orbital rim. The tumor causes exophthalmos associated with proptosis and some limitation of motion. The treatment of the choice is radical excision of the tumor and followed by x-ray radiation. A 40 year old Korean woman had a hard, nontender mass on the left supraorbital region which had developed for about three years. The encapsulated orbital tumor was removed surgically and found to be a mixed tumor histopathologically.

As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

BACKGROUND: The pathogenesis of atopic dermatitis is still unknown. Many reports have suggested that the house dust mite antigen may play a role in the pathogenesis of atopic dermatitis. The IgG4 allergen-specific subclass has been considered to be involved both in allergic reactions and associated with the appropriate response to allergen-specific immunotherapy. OBJECT: The purpose of this study was to evaluate the positive rate of the allergic prick test to D. farinae and the levels of D. farinae-specific IgE and Ig64. METHODS: We performed the allergy prick test, RAST for D. farinae-specific IgE and ELISA for D. farinae-specific IgG subclasses and compared the values between atopic dermatitis patients and normal controls. RESULTS: 1. D. farinae was the most common allergen in patients with atopic dermatitis and the positive rate of the allergic prick test was 61.0%. The positive rate of the allergic prick test and the positive rate to D. farinae increased as c]inical grading increased. 2. The Positive reaction rate of D. farinae-specific IgE(RAST) in those with atopic dermatitis was 68.8% and increased as the positive reactions of the allergic prick test to D. farinae and chnical grading increased. 3. Among the IgG subclasses, only the level of D. farinae-specific IgG4 was significantly higher in atopic dermatitis than normal controls. 4. The level of D. farinae-specific IgG4 showed a tendency to decrease in accordance with the clinical severity grades. CONCLUSION: These results suggested that D. farinae might play an important role in the development of atopic dermatitis and well-designed studies should continue to be performed in order to delineate the biological significance of IgG4.

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.

Spinal Fractures*

Periprosthetic fractures after total hip arthroplasty or hemiarthroplasty are an uncommon complication. These fractures have problems of fixation of fracture and stability of the femoral component. Ipsilateral femoral fractures after hip arthroplasty occurred in 14 cases (11 patients) out of 510 hip arthroplasties performed between January 1985 and May 1996. These fractures occurred at an average of 3 years and 6 months after primary hip arthroplasty. These fractures were classified by Johansson classification. Nine fractures were treated with plate and cerclage wires. Four fractures were treated with skeletal traction. Bone graft was applied to the fracture site in 9 fractures which were treated by open reduction and internal fixation with plate and cerclage wires. Average follow up period was 21 months. The results were as follows. 1. All but three of the fractures had been developed by low energy trauma. Seven patients had osteolytic lesion around femoral component. Of the seven patients who had osteolytic lesions, six patients had periprosthetic fractures which connected with osteolytic lesions. We think that osteolysis is one of the important factors of the periprosthetic fractures after hip arthroplasty. 2. Four cases were treated by skeletal traction. One case had malunion. Progressive subsidence of femoral component was noted after union of fracture in 3 cases. Therefore these periprosthetic fractures which had an osteolysis and subsidence preoperatively should be managed with operative methods. 3. Nine fractures which had treated with plates and autogenous bone graft showed good hip joint function with stable femoral component. We think that stabilization of periprosthetic fractures with plates and cerclage seemed to be a good method for femoral fractures after hip arthroplasty.

PURPOSE: The objective of this study was to evaluate an immunoassay for urinary nuclear matrix protein (NMP22) as an indicator for transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Three groups of subjects attended the trial of NMP22. First group was 27 patients with transitional cell carcinoma of the bladder, second group was 24 patients with other urinary cancer consisted of prostate cancer and renal cell carcinoma, and third group was 24 healthy volunteers. NMP22 was determined using a commercial test kit, which is based on an enzyme-linked immunosorbent assay. RESULTS: In normal healthy volunteers and other urinary cancer group median NMP22 levels were 2.24 and 3.27 U/ml, respectively. Median urinary NMP22 levels in patients with transitional cell carcinoma of the bladder were 54.30 U/ml. It was significantly greater than other two groups. Median NMP22 levels according to the tumor stage and the tumor grade did not show the significant difference statistically. CONCLUSIONS: Urinary NMP22 is a useful marker that is more specific for bladder cancer thsn for other urinary cancer. Further tests are required to clarify the influence of other spe- cific conditions, such as urinary tract infection, and intravesical drug instillation or procedure.
