OBJECTIVE: The aim of the study is to evaluate the changes of the respiratory patterns associated with swallowing in the brain-injured patients. METHOD: Twenty brain-injured patients(6 bulbar lesions, 14 pseudobulbar lesions) and fifteen normal subjects were selected for this study. Each subject swallowed 5cc of water for ten times in a upright sitting position and a submental electromyography recording and respirography by pneumobelt on mid-abdomen were recorded simultaneously. RESULTS: 1) Most swallows occured during the late expiratory phase in both brain-injured patients and controls. 2) In brain-injured patients, the incidence of swallowing during inspiration was significantly higher than the controls(p<0.05). 3) In brain-injured patients, the postdeglutitive inspiration was significantly higher than the controls(p<0.05). 4) In patients with a bulbar lesion, the postdeglutitive inspiration was significantly higher than patients with a pseudobulbar lesion(p<0.01). 5) Postdeglutitive swallowing relatively correlates with the abnormalities in clinical findings and Video Fluoroscopic Swallowing Study(VFSS) findings. CONCLUSION: The respiratory patterns associated with the swallowing in brain-injured patients were different from that of the normal adults and the postdeglutitive inspiration could be the most valuable predictor of the aspiration.

The lymphoepithelial cyst (LEC) rarely occurs in the thyroid gland. The LEC has been thought to be related to developmental rest, namely solid cell nest, which is derived from ultimobranchial body. We report a case of lymphoepithial cyst in a 34- year-old woman clinically diagnosed with Hashimoto's thyroiditis. The cyst was located in mid to lower portion of the left lobe. It was a single unilocular cyst, which for the most part was lined with squamous epithelium, and at certain foci with ciliated columnar epithelium. The cyst wall showed a dense lymphocytic infiltration, numerous lymphoid follicles with germinal centers and admixed thyroid follicles. This morphology is similar to the branchial cleft cyst, with the exception of the thyroid follicles in the cyst wall. Near the cyst were several solid epidermoid cell nests. Immunohistochemical stain of this cyst-lining epithelium and solid cell nests showed CEA positivity. In view of the similarity in histomorphology and CEA positivity to branchial cleft cyst of the lateral neck, the LEC of the thyroid could also have been of branchial origin. However, the admixed thyroid follicles in the cyst wall suggests that the LEC of the thyroid gland might have derived from another branchial cleft as a ultimobranchial body, because it has the potential for thyroid follicular differentiation.

Between Feb. 1992 and Apr, 1995, the authors have performed arthroscopic abrasion arthroplasty in 78 knees of 76 patients with degenerative osteoarthritis. The followup period was between 24 and 58 months, with on an average of 41 months. All patients had Zarins grade IV articular cartilage change. The results were as follows. 1. Of the total 78 knees, results were excellent in 25(32%), good in 33(42A), fair in 12(17%), poor in 8(10%) knees respectively. 2, The best results were obtained patellofemoral abrasion arthroplasty. 3. The poor results were obtained in patients with the both femoral condyle, lesion. 4. The results were much better in young age group (below 40 years). Aroscopic abrasion arthroplasty is not a curative but palliative method. But it could be an appealing altemative to total knee arthroplasty or high tibial osteotomy or can be performed postoperated after these reconstructive proeedures.

This study was designed to investigate whether sectioning of the transverse carpal ligament (TCL) modifies the biomechanical behavior of the finger flexion in respect to dynamic changes of the wrist. Changes of work, load, and excursion of the flexor tendons were measured using fresh frozen cadaver hands with the wrist in 30° flexion, neutral, and 30° extension before and after division of the TCL. Change in work efficiency between intact and cut TCL groups was noted most with the wrist in flexed position (12.5%) compared to 3% in neutral wrist position and no change in wrist extension. The extended wrist group as a whole had greatest increase in the efficiency of work and load with greater than 16.2% and 14.8% changes, respectively. The significant decrease in the excursion efficiency of the flexor tendons was demonstrated when the wrist was in the flexed position. This effect was accentuated when the TCL was divided causing the bow-stringing phenomenon. The increase in the excursion of the flexor tendons could clinically result in decreased grip strength when the wrist is flexed. Furthermore, the effects of TCL division were least significant when wrist position was in extension. One could conclude from this that post-operative management after carpal tunnel release procedures should include placing the wrist in moderate extension.

Trichinellosis is a parasitic zoonosis of public health importance. It is caused by Trichinella spiralis which has a wide host range including humans. In the present communication, the ELISA technique was employed on a total of 803 blood samples from 7 selected pig breeding farms in 1996 for diagnosis and surveillance of trichinellosis. Out of the entire 803 samples, nine were found to be suspected while one was positive by ELISA. But western blot analyses employed for further confirmation have shown that all of 10 samples did not react to larval excretory-secretory product antigens. These results indicate that pig breeding farms included in the present study are free from trichinellosis. However, it does not mean Korea is free from trichinellosis since human trichinellosis has recently been reported. The necessity of continued surveillance for trichinellosis in both pigs and wild animals was discussed.
