PURPOSE: We studied CT findings of bronchioloalveolar carcinoma that manifestated varied clinical and radiologic characteristics. MATERIALS & METHODS: We studied presenting radiographic patterns and their characteristics and secondary findings of histologically proven 30 cases of bronchioloalveolar carcinomas on chest CT scan. RESULTS: Bronchioloalveolar carcinoma appeared radiologically as a solitary nodule(19 cases), consolidation (7 cases), and multinodules(4 cases). A solitary nodular type shows irregular or spiculated borders, peripheral or subpleural location, heterogenous density, pleural tags, pseudocavitation, and sometimes rim-enhancement of mass. A consolidation type shows air-brochogram, pseudocavitation and CT anglogram within homogenous low attenuated consolidated lung. Hilar and mediastinal lymphadenopathy as secondary findings of bronchioloalveolar carcioma appeared frequently(43.3%). Even in a solitary nodular form, hilar & mediastinal lymphadenopathy was noted in 36.8% and follow-up study in 6 cases showed lung-to-lung metastasis with 14.7 months in mean metastasis duration. CONCLUSION: It is difficulty in diagnosis of bronchioloalveolar carcioma with clinical or plain radiographic features alone because of theis variability. We found that CT scan can help the diagnosis of this tumor. We also found out that a solitary form of bronchioloalveolar carcioma as well as diffuse form does not have a good prognosis.

PURPOSE:Chronic autoimmune thyroiditis is the most common thyroid disease in children and adolescents, and also is the most common cause of hypothyroidism in children and adolescents. We studied the clinical manifestations and natural courses of chronic autoimmune thyroiditis in children and adolescents. METHODS:We analyzed retrospectively twenty one children and adolescents who were diagnosed as chronic autoimmune thyroiditis before 15 years of age. The diagnoses were made from July 1997 to February 2004 at Ajou Univesity Hospital. We reviewed the clinical manifestations and thyroid functions of these patients. RESULTS:Nineteen patients were female and two were male. The mean age at diagnosis was 9.95+/-3.1 years, the mean duration of follow up was 23.52+/-22.98 months. At diagnosis, the most common chief complaint was goiter (15 patients/21 patients) and the others were short stature, easy fatigue, cardiac murmur and weight loss. Eighteen patients had goiters at diagnosis. Four had familial history of thyroid disease, Three of them had maternal history of thyroid disease and one had paternal history of thyroid disease. At diagnosis, Seven patients were euthyroid and four patients were hyperthyroid, eighteen patients had antithyroglobulin antibody, seventeen patients had antimicrosomal antibody, fourteen patients had both of them. At last follow-up, eight patients were euthyroid and ten patients were hypothyroid, three patients were hyperthyroid. CONCLUSION: Chronic autoimmune thyroiditis in children and adolescents can have the various important influences on the metabolism including the growth. The clinical manifestations and thyroid functions should be monitored in children and adolescents with chronic autoimmune thyroiditis.

Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.

Proximal femoral nail anti-rotation (PFNA) with a lag screw that is shaped like a spiral blade shape is an orthopedic implant to fix trochanteric fractures of the proximal femur. In addition the reason of the biomechanical advantages, PFNA widely been used recently. We report an 83-year-old man with excessive sliding of the helical blade and a femoral neck fracture after AO/OTA type A2 intertrochanteric fracture, which was fixed with a PFNA.
