1.Effect of decorin on tensile strength of healing flexor tendon.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2000;27(1):83-86
Adhesion formed between tendon and its sheath after repair often impairs functional recovery. There have been many attempts to reduce adhesion around a repaired tendon, but most results have been unsatisfactory or impractical in clinical application. Moreover, most attempts were focused on extrinsic tendon healing. whereas studies on the intrinsic tendon healing are sacrce in the literature. We have previously reported that fibrotic tendon adhesion after repair was decreased by decorin, a natural inhibitor of TGF-beta. Accordingly, the serial tensile strength was measured after complete tensection and repair of the tendon severance in order to confirm the effect of decorin inhibition of intrinsic healing capability. Forty White Leghorn chickens were subject to complete transection and repair of the third toe flexor digitorum profundus tendon in Zone II. In the experimental group, 0.5ml of diluted decorin(50microgram/ml) was injected around the repaired site, and the same volume of saline solution in the control group. Tendons were harvested at 1, 3, 5 and 7 weeks. The disrupting force of the repair site was analyzed using tensiometry(LLOYD LR 30K, U.K). The tensile strength of repaired tendon was similar in both groups for all postoperative periods. This indicates that intrinsic healing proceeds normally within the decorin group in spite of the blockade of TGF-betaactivity. Decorin, a natural inhibitor of TGF-beta, showed a significant inhibitory effect on reducing post-repair tendon adhesions, without disruption of intrinsic healing in the chicken flexor tendon injury model. Therefore, decorin is expected to be a useful agent for preventnion on tendon adhesion after the repair in clinical usage.

BACKGROUND AND OBJECTIVE: The clinical manifestation of Henoch-Schonlein purpura and existance of renal involvement may influence on its course and prognosis. To verify prevention with early administration of steroid, we studied the efficacy of corticosteroid treatment. MATERIAL AND METHOD: We analysed 65 children under 15 years of age with Henoch-Scho nlein purpura according to their age, sex, and seasonal incidence. Forty children showed typical skin lesions, arthralgia and abdominal pain. We have divided them two groups. Group A consisted of 20 children who received 1 mg/kg of prednisolone/perday for 2 weeks and group B did not. We carried out their physical examination and urinalysis monthly for a year. RESULT: The main clinical manifestations were skin rash(100% ), abdominal symptoms(41.5 %), joint symptoms (49.2%), and renal involvement(34%). As for gastrointestinal symptoms, abdominal pain(66.7% ) was most commonly observed one and others were nausea or vomiting (44.7%) and melena(25.9%). The joint involvement was observed mostly in knee(56.3%) and ankle joint(31.3% ), Hematuria was observed in all cases with renal involvement and proteinuria, in 28% of them. The improvement of renal manifestations were noted in 84.2% of them within 4 months. Mild elevation of IgA was more frequently observed in renal involvement group than non-involved group (p< 0.01). There were no significant differences in immonologic parameters such as IgG, IgM, IgE, duration of the acute phase and severity of cutaneous symptoms between two growps. None of steroid treated growp showed progression of nephropathy. Of the 20 non-steroid treated growp, 2(10%) developed nephropathy. Conclusion We may suggest that existance of renal involvement in Henoch-Schonlein purpura influences its course and prognosis.

We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.

Phakomatosis pigmentova.scularis is a disease complex with dermal melanocyto sis such as nevus of Ota, nevus of Ito, or Mongolian spots and extensive hemangiomatous change such as nevus flammeus, which are associated with systemic organ involvement. We report a 23-year-old female, who showed bilateral nevus of Ota and nevus of Ito with widespread nevus flammeus and Mongolian spots since birth. She was also associated with megalocornea due to congenitol glaucoma and cataract.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

OBJECTIVES: The multiple sleep latency test (MSLT) is commonly used as a valid objective measure of sleepiness. The procedure of MSLT is well standardized but the sleep onset criterion is somewhat variable. One epoch of stage 1 sleep is the most commonly used criterion, and the criterion of three epochs of stage 1 sleep is also used. The purpose of this study was to compare the two criteria used to determine sleep onset. METHODS: We retrospectively analyzed 60 consecutive MSLT that were performed according to a standaridized protocol. We scored each test using the two different criteria for sleep onset and then statistically analyed the results. RESULTS: Using the different criteria, 20 patients among 60 showed changes in mean sleep latency (33.3%). The extent of change ranged from 1.3% to 38.5% (mean 15.9%). Non-narcoleptic patients showed a significantly higher incidence of change than other sleep disorder patients. CONCLUSION: Changes in mean sleep latency occurred according to the different criteria of sleep onset. But the difference arising from different criteria was statistically not significant in patients with moderate to severe sleepiness. Considering that 1 epoch criterion for sleep onset is more sensitive in detecting clinically significant sleepiness, the authors suggest that the 1 epoch criterion is more reliable than the 3 epochs criterion.

Cavernous angiomas are considered to be congenital in origin. Patients under age of 14 years usually does not require imaging because they are likely to have a benign abducens nerve palsy, unless they develop additional signs or symptoms of neurologic disease during observation. Here we report a case of an isolated abducens nerve palsy caused by overt hemorrhage from de novo formation of cavernous angioma in the pons. Cavernous angiomas of the brain stem should be considered as a possible cause of isolated abducens nerve palsy in young adult and MRI, including gradient-echo sequences should be performed.
