A clinical application of the arthroscopy to the three hundred symptomatic knees were performed, and seven knees with a symptomatic seprated suprapatellar bursa were successfully managed and followed by arthroscopic surgery at the Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital from May 1983 to May 1985. The results obtained are as follows; 1. Separated suprapatellar bursa may cause some internal derangement of the knee. 2. The incidence of the separated suprapatella bursa in our view was 5% that is, of 300 symptomatic knees. 3. Separated suprapatellar bursa may have to be excised under arthroscopy.

BACKGROUND: Atracurium is a benzylisoquinolium nondepolarizing neuromuscular blocking drug. It releases histamine upon the rapid administration of more than 2 x ED95. Cisatracurium is about three to four times more potent than atracurium, less likely to release histamine, and has weaker cardiovascular or autonomic effects. Mivacurium releases histamine to about the same degree as atracurium at the same dose. This study was undertaken to reevaluate the experimental model for the evaluation of effects on the autonomic nervous system, and to determine the neuromuscular blocking profiles and the vagolytic effects of atracurium, cisatracurium and mivacurium in cats. METHODS: Cats, either sex, anesthetized with pentobarbital, were used. Neuromuscular blocking effects were assessed using the effects on the anterior tibialis muscle twitch evoked with supramaximal stimuli (0.2 ms-duration, 0.1 Hz). Inhibition of the parasympathetic nervous system was assessed in response to bradycardia to vagal nerve stimulation with ten-second trains of square-waves (0.5 ms-duration, 20 Hz). The dose-response curves for both neuromuscular blocking and vagolytic actions were determined for each animal. The dose-response curves were constructed in cumulative fashion. The response for vagal stimuli was measured two minute after each dosing. Vagal ID50 (The doses that produced 50% inhibition of the response to vagus nerve stimulation) were determined. RESULTS: NMB ED95 and NMB ED50, respectively, were 102.0 +/- 28.3 and 143.7 +/- 40.5 microgram/kg for atracurium, 81.4 +/- 13.3 and 110.7 +/- 18.8 microgram/kg for cisatracurium, and 56.8 +/- 17.4 and 74.2 +/- 25.0 microgram/kg for mivacurium. Vagal ID50 was 2,654 +/- 1,651 microgram/kg for atracurium, 655 +/- 389 microgram/kg for cisatracurium, and 606 +/- 182 microgram/kg for mivacurium. The vagal ID50/NMB ED95 and vagal ID50/NMB ED50 were 18.5 and 26.0 for atracurium, 5.9 and 8.1 for cisatracurium, and 8.2 and 10.7 for mivacurium. CONCLUSIONS: Atracurium has a wider margin of safety only for vagal stimulation as compared with cisatracurium and mivacurium. However, we couldn't exclude that either sympathetic stimulation or histamine release might contribute to heart rate.

BACKGROUND: To determine the natural progression of conservatively treated rotator cuff tears, we evaluated changes in radiologic and clinical parameters in patients whose recalcitrant tears were neglected after conservative treatment. METHODS: A total of 73 patients with recalcitrant rotator cuff tears in spite of conservative treatment were included in this study. We measured changes in tear size and in the extent of fatty infiltration of the rotator cuff by comparing the initial and final follow-up magnetic resonance imagings (MRIs). To determine factors influencing the change in tear size, we collected the medical history of patients taken at the time of initial admission. RESULTS: The average follow-up period was 20.1 months, and the average increase in tear size across this period was 6.2 mm. In terms of steroid injection, we found that the increases in tear size of the steroid injection group (p=0.049) and of the sub-group that had received more than three steroid injections (p=0.010) were significantly greater than that of the non-steroid injection group. CONCLUSIONS: We found that the increase in cuff tear size was on average 6.2 mm across the follow-up period, indicating that neglecting cuff tears may cause them to progress into more severe tears. We also observed that a history of steroid injection might be a possible risk factor for a worse prognosis of cuff tears. Therefore, we suggest that patients with rotator cuff tears and a history of steroid injection are recommended aggressive modes of treatment such as surgery.

BACKGROUND: Lyme disease, an infection caused by Borrelia(B.) burgdorferi, has been reported in many countries. But in Korea, only 5 cases of serologically diagnosed lyme disease have been reported. Because several strains of B. burgdorferi were isolated from Ixodes ticks which were captured in Kangwon and Chungbuk province, there might be more cases of serologically undiagnosed lyme diseases presenting with erythema migrans. OBJECTIVE: To understand the clinical patterns and laboratory findings of erythema migrans in Korea. METHODS: A clinical survey was retrospectively performed on 9 patients with erythema migrans which occurred after tick bites. RESULTS: Among 9 patients with erythema migrans, 3 patients were male and 6 patients were female. The onset age of erythema migrans ranged from 26 to 71 years old (mean, 51.3 years old). The mean duration of erythema migrans after tick bite was 26.4 days and the diameter of the lesion ranged from 6 to 34 cm (mean, 18.3 cm). All cases developed from May to September and systemic symptoms such as fatigue, fever and/or chills, myalgia, palpitation, headache, arthralgia and dyspnea were present at the time of hospital visits of 3 patients. Clinically, 3 patterns of erythema migrans were seen; typical target pattern, homogenous and erythematous plaque pattern, and linear solitary plaque pattern with central postinflammatory pigmentation. Only 2 of the 7 patients (28.6%) were seropositive for IgM and IgG antibody titers by enzyme-linked immunosorbent assay in consecutive serologic tests. PCR for Borrelia DNA in paraffin-embedded tissue showed full negativity in 6 patients with erythema migrans. CONCLUSION: Although lyme disease is not endemic in Korea, some patients with erythema migrans might be undiagnosed as lyme disease serologically with erythema migrans. To take into consideration false negative serelogic results in early erythema migrans, early oral tetracycline therapy should be included through clinical and historical diagnosis.

We aimed; 1) to determine the validity of the EuroQol 5D (EQ-5D) for the health-related quality of life (HRQOL) of Korean patients with type 2 diabetes, and 2) to identify associated factors of the HRQOL of these patients. Follow-up surveys were conducted for consecutive patients with type 2 diabetes. HRQOL was assessed using the EQ-5D and the Short Form-36 (SF-36). The validity of EQ-5D was assessed with the perspectives of known group, convergent and discriminant validity. Additionally, a linear mixed model using a backward elimination was used for identify associated factors. Of the 1,072 patients included in the first survey, 858 (80.0%) completed the questionnaires in the follow-up. In the known group validity, the problem rates in each EQ-5D dimension were highest among women, elderly people, and less-educated subjects. The Spearman's rho between the EQ-5D and the SF-36 scales were larger in the comparable dimensions than those in the less comparable dimensions. In the final model, we found that sex, age, education, body mass index, atrial fibrillation, stroke, and retinopathy were statistically significant. Our data suggest that the EQ-5D is a valid tool for Korean patients with type 2 diabetes and that various factors could affect their HRQOL.

PURPOSE: To observe MR findings of vascular abnormality in Sturge-Weber syndrome and to determine the value of MRI in diagnosis. MATERIALS AND METHODS: Ten patients with Sturge-Weber syndrome (age : 3 months-32 years)were evaluated by MR imaging ; in six and four cases, respectively, the results were correlated with those of CT and angiography. We retrospectively analysed changes in the cortical vein and deep venous system, including the medullary and subependymal vein, as well as an largement of the choroid plexus, leptomeningeal enhancement, and changes in diploic space. RESULTS: In all cases except one, in which non-contrast enhanced study had been performed, varying degrees of leptomeningeal enhancement were seen. In nine cases the cortical vein became smaller; enlargement of the choroid plexus was seen in eight cases, change in the diploic space in seven (including three in which there was angiomatous involvement), and enlargement of the deep venous system in seven. In younger patients, collateral pathways were less developed and leptomeningeal angiomatous changes were more pronounced than in those who were older. CONCLUSION: MRI is a useful modality for the evaluationn of vascular changes in Sturge-Weber syndrome. These changes vary according to a patient's age and the duration of the disease.

BACKGROUND: Cisatracurium is a nondepolarizing muscle relaxant. It less likely release histamine and has better cardiovascular stability. It presumably undergoes pH and temperature- dependent, nonenzymatic chemical process, Hofmann reaction. In vitro studies, Hofmann reaction was enhanced with increasing pH, but, in vivo the influence of acid-base imbalance is not well defined. METHODS: To evaluate the effects of acid-base imbalance on the neuromuscular blockade of cisatracurium in the cat, we induced acid-base imbalance and performed cumulative dose-response studies. RESULTS: ED50 of the cisatracurium was significantly reduced in all groups. Dose-response curves from all acid-base imbalance groups did not have significant differences in slopes. But, all showed shift-to-left when compared with control curve, showing decreased ED50. Duration of action was not affected. Recovery index was significantly changed in respiratory and metabolic alkalosis. CONCLUSIONS: It may be concluded that acid-base imbalance significantly augmented the potency of cisatracurium, but, changes of recovery index in this study may be resulted from systemic instability such as unstable hemodynamic state by the prolonged experiment.

Apraxia of lid opening is a nonparalytic motor abnormality characterized by difficulty in initiating the act of lid elevation. It has been reported in various extrapyramidal disorders(Parkinson's disease, Huntington's chorea, progressive supranuclear palsy), right middle cerebral infarction and Wilson's disease. We report a case of apraxia of opening in Wilson's disease, 34-year-old man was noted to have resting tremor and voluntary eye opening difficulty. Wilson's disease without Kayser-Fleisher ring was diagnosed by serum Cu, serum ceruloplasmin and liver biopsy. He was treated with D-penicillamine anticholinergics, amantadine, and levodopa.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It's rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.
