Clothing dermatitis frequently goes unrecognized either becaue he clinical picture is mistaken for other disorders, such as seborrheic dermatitis, and prurius, or beacuse it is difficult to trace the causal agent. Contact dermatitis to disperse dyes, especially to azo dyes, has been well known and the most frequent sources of sensitization to dyes are dresses, stockings, and trousers made of synthetic fabrics We described a case of hat band contact dermatitis due to disperse dyes, proven by a patch test. Although chrome was not proven by the diphenylcirbizide method, many dyes known to be contact allergens were proved in different kinds of hat bands.

The pleomorphic adenoma is the most common neoplasm involving both the major and minor salivary glands. It is a benign, slowgrowing tumor, but local recurrences can occur. The pleomorphic adenoma gene 1 (PLAG1), which is a novel zinc finger gene, is frequently activated by reciprocal chromosomal translocations involving 8q12 in a subset of salivary gland pleomorphic adenomas. This experimental study was preformed to observe the translocation patterns between PLAG1 gene and the three translocation partner genes. We also have analyzed the presence of PLAG1 transcripts by RT-PCR. CTNNB1/PLAG1 gene fusion was observed in three of nine pleomorphic adnomas. However, LIFR/PLAG1 and SII/PLAG1 gene fusions were not detectable. All of three gene fusions was not detectable in one Warthin's tumor and three inflammatory salivary gland tissues. PLAG1 transcripts were expressed in all inflammatory salivary gland tissues and tumors except for three pleomorphic adenomas. Of particular one pleomorphic adenoma showing CTNNB1/P AG1 gene fusion did not express PLAG1 transcipt. Our data indicate that gene fusion involving PLAG1 is a frequent event in pleomorphic adenoma, but correlation between gene fusion involving PLAG1 and PLAG1 transcription is not definite.

This study was carried out to investigate the morphologic characteristics and localization of antigenic molecules of Pneumocystis carinii in experimentally induced P. carinii pneumonia in rats. After six weeks of administration of low protein diet and dexamethasone, Sprague-Dawley rats were sacrificed to submit lungs or bronchoalveolar lavage for the study. Monoclonal (092, 900, 902, and 904) and polyclonal (SP-D) antibodies were used for immunohistochemistry and immunoelectron microscopy (ITEM and ISEM). Immunohistochemically P. carinii organisms were well identified as clusters or separated forms in the alveolar spaces being frequently attached to the alveolar walls. Immunoelectron microscopically the adherences of gold particles were observed on the surface of all stages of the P. carinii. Occasionally positive immunogold labeling was observed in the cytoplasm of the trophozoites and on the pellicle of the intracystic bodies within the cysts. The monoclonal antibodies 092, 900, 902, and 904 reacted mainly with pellicles of P. carinii, whereas SP-D labeled on the pellicles, intracystic bodies, cytoplasms of the alveolar macrophages, and free floated surfactant material in the alveolar spaces. The immunogold particles were observed more diffusely and intensely in the cysts than in the trophozoites. These results indicate that antigen is mainly localized on the pellicles, and accumulated during development from the trophozoite to the cyst stages.

ACL plays an important role in stability of knee joint and its injury causes instability of joint which is known as the initiation of problem knee. Reconstruction of the anterior cruciate ligament would be preferred to the primary repair in treatment. And recently with the advance of arthroscopic technique and development of bone-patellar tendon-bone (BPB) graft material, the result of reconstruction is somewhat superior to that of primary repair. Authors compared the results of 20 primary repairs (Group I ) and 20 reconstructions (Group II) among 64 acute ACL injury treated Sung-Ae General Hospital from January 1989 to December 1994. The results were as follows: 1. Most common associated injuries were medial collateral ligament rupture and medial meniscal tear. 2. Group I showed postoperatively 13 negative anterior drawer test, 12 negative Lachmann test and 12 negative pivot shift test and group II showed postoperatively 17 negative anterior drawer test, 15 negative Lachmann test and 17 negative pivot shift test. (p<0.05) 3. In postoperative Lysholm knee scoring scale, group I showed 86 points and group II showed 93 points (p<0.05). 4. In postoperative KT-1000 arthrometer, 12 cases in Group I and 16 cases in Group II showed less than 2mm difference with sound side (p<0.05).

Traumatic dislocation of the hip presents serious problems that may lead to avascular necrosis, nerve palsy, post-traumatic arthritis even when reduction is promptly and adequately carried out. Among them avascular necrosis is the most important prognostic factor, so the early detection of this complication has critical significance for final result. Bone scan has been considered one of early diagnostic test, but recently MRI replaced its role for imaging in the detection of early AVN, treatment monitoring and prediction of prognosis. Authors prospectively studied the early finding of MRI to detect avascular necrosis of the femoral head and to predict prognosis in traumatic hip dislocation and fracture-dislocation. From December 1990 to November 1994, 12 case of dislocation and fracture-dislocation of the hip were studied . In follow up period ranging from 19 months to 65 months, 10 case had excellent or good result. All cases had abnormal MRI finding such as paraarticular edema, capsular bulging, joint effusion, femoral head fracture, but findings such as femoral head signal changes were dectected in only 3 cases. Among the 3 cases, 1 case had developed AVN and 2 cases were uneventful. Other complications were 3 cases of posttraumatic arthritis, 2 cases of incomplete sciatic nerve palsy, and 1 case of heterotrophic ossification. Although early MRI finding at posttrauma 2weeks gave less specific information, it could give good information for risk group and follow up control with more cases. Although it is expensive, MRI can be one of the most reliable reference in early diagnosis of AVN and prediction of prognosis in traumatic dislocation and fracture- dislocation of the hip with non-invasive method.

Acetabular bone deficiencies encountered during the revision hip arthroplasties should be recon- structed to provide the implant stability and to restore the normal center of rotation of hip and the leg length. We revised the loosened acetabular cup by grafting fresh-frozen bulk femoral head and inserting uncemented cup in 17 hips of 15 patients. The average follow-up period was 2 years and 3 months. The acetabular bone deficiencies were type 2A in 6 hips, type 2B in 8, type 3A in 1 and type 3B in 2 by Paprosky's classification. Three blocks of femoral head were grafted in 3 type 3 deficiencies, but only one in type 2 deficiencies. The cup-host bone contact was 41% on the average. However, the cup-host bone contact in the zone I was present only in 12 out of 17 hips and its average was 14%. Incorporation of the allograft into the host bone occurred between 5 months and 1 year and 7 months (average, 8,6 months) after revision surgery. Significant radiographic loosening sign was noted only in 2 hips which had not only type 3B bone deficiencies reconstructed with 3 blocks of femoral head allograft but also no cup-host bone contact in zone I . The bulk allograft of fresh-frozen femoral head demonstrated acceptable results in type 2 acetabular bone deficiencies, although the follow-up period was relatively short. Reconstruction of type 3B acetabular bone deficiencies by using multiple blocks of femoral head allograft had been failed. We presumed that the lack of the graft stability and the intimate contact between the grafts and host bone was the cause of failure.

Fractures of the metacarpal and phalanx of the hand are common occurances and bony union usually occurs without difficulties. If complication of the metacarpal and phalangeal fracture of the hand occurred, it causes significant functional deficit. The authors have reviewed 92 patients, 121 cases of metacarpal and palangeal fracture of the crushed hand which were treated with internal fixation with/without open reduction in the deparment of orthopaedic surgery in Holy Family Hospital from Jan. 1985 to Dec. 1989. The authors obtained the following results ; 1. The incidence of nonunion and delayed union was 12.4% (15/121 cases). 2. The criteriae of nonunion and delayed union are progressive angulation at fracture site after removal of implant, lack of bony union evidence in the radiography more than 12 weeks after injury, tenderness and pain on motion at fracture site and gross pseudomotion. 3. Nonunion and delayed union occurred more commonly in phalangeal fractures, shaft fractures, severely traumatized fractures (open fractures, marked displaced fractures, comminuted fractures and fractures had associated injuries in the same hand) and under-reduced fractures after internal fixation. 4. Mean TAM (total active motion) range at last follow up was 94.5°in thumb and 186.6°in finger and that of nonunion and delayed union cases was 89°in thumb and 153.5°in finger.

The authors report the clinical results of ten cases of complex supracondylar fractures treated by external fixation with a mean follow up of 21 months. Six cases were closed comminuted fracture, and four cases were open fractures. By AO classification six cases were type C2, two type C3, one type Al, and one type A3. Four cases had associated vascular injury. Reduction was performed by closed method in eight cases, and two cases were reduced through open wound. All cases healed at average of 142 days. Final healing of all cases occurred with an average range of motion of 3°-119° except one case which required reapplication due to infected nonunion with a gap. In nine cases of the ten functional results were rated as "good", and one case was "fair" by Iowa Knee Rating Scale. In conclusion, definitive external fixation can be a good alternative treatment modality despite previous recommendations to limit external fixation to temporary application in cases of limb salvage, such as severe comminution or pre-existing infection.
