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.

There has been considerable controversy in the treatment of acute grade 3 injuries of acromioclavicular joint. Neviaser reported that the possibility of a latent degenerative arthritis occurring in the acromioclavicular joint as the result of passing Kirschner wire through the joint was more theoretical than real and any changes that may take place in the acromioclavicular joint were the result of trauma. The acromioclavicular joint and the articular disc were not disturbed at the time of operation in Neviaser technique, but we excised the articular disc that were torn for the purpose of preventing acromioclavicular joint from degenerative arthritis. We had treated 26 cases of grade 3 injuries of acromioclavicular joint with modified Neviaser technique from June 1990 to May 1994 at the Pohang St. Mary’s Hospital. The results were as follows. 1. The clinical results by Weitzman were consisted of 18 cases(69%) of excellent, 6 cases(23%) of good, 2 cases(8%) of fair and 0 case(0%) of poor. 2. Loss of reduction was 1.6mm by stress views of final reviews and didn’t affect to functional result. 3. There were no cases of redislocation of acromioclavicular joint after removal of Kirschner wires. 4. There were no cases of degenerative arthritis of acromioclavicular joint in final review. There result suggest that excision of the articular disc that were torn may be helpful in preventing acromioclavicular joint from degenerative arthritis.

BACKGROUND: Recent DNA polymorphism analysis using numerous DNA markers has been used to determine the parental origin of the extra chromosome 21 in Down syndrome. In this study we used seven dinucleotide repeat polymorphisms on chromosome 21 to characterize a case of rea(21q21q) and to know whether it is consistent with an isochromosome or a true Robertsonian translocation. METHODS: Cytogenetic investigation was done by conventional G banding DNA was extracted from whole blood of a proband and her parents and was amplified by PCR using seven sets of (GT)n repeat dinucleotide markers located on the long arm of chromosome 21 After electrophoresis of the PCR product in polyacrylamide gel and silver staining the parental origin and number of DNA copy were determined by visual comparison of the band intensities within and between individuals. RESULTS: Conventional cytogenetics showed that the proband had a 46.XX.re(21q21q) chromosome pattern. Parental chromosome studies were normal, therefore, the rearrangement was a de novo event. All seven DNA markers showed one or two alleles, demonstrating rea(21q21q) to be an isochromosome. For D21S215 and D21S156 markers both parents were heterozygous and the proband inherited one copy of paternal allele and two copies of maternal allele which both parents did not share. This finding was consistent with a maternally derided isochromosome. CONCLUSION: Use of dinucleotide repeat DNA polymorphisms after PCR amplification will be very useful to detect the parental origin of additional chromosome 21 or rearrangement of chromosome 21 in Down syndrome. Besides employing siltier staining of a PCR product we will be able to avoid using of radioisotopes and apply to clinical laboratory diagnosis.

INTRODUCTION: Several methods, including loss of eye lash (eyelash) reflex and loss of verbal contact, have heen used as criteria for estimating the optimal hypnosis for anesthesia induction. However, these methods are too objective. We examined the hypnotic dose response of etomidate, using a bispectral index as a more subjective criterion for anesthesia induction. METHODS: Fourty-Five ASA I or II adult patients scheduled for elective orthopedic surgery were randomly allocated to three groups according to induction dose of etomidate. They were Group 1: 0.1 mg/kg ; Group 2: 0.15 mg/kg; Group 3: 0.2 mg/kg (n = 15 for each group), respectively. Etomidate diluted as 10 ml in a syringe injected through an 18G forearm intravenous catheter, using a syringe pump at the rate of 20 ml/min. Observer's Assessment of Alertness/sedation (OAA/S) scale of 1 was considered optimal for hypnosis. Bispectral index, OAA/S scale, and vital signs were checked every minute until spontaneous eye opening after end of drug infusion. Also, the correlation coefficient between BIS and OAA/S scale was checked for evaluating the bispectral index; this was a useful tool for estimating the degree of hypnosis. RESULTS: BIS and OAA/S showed their lowest scores around 60 sec. after the etomidate injection, which was very different from time to peak effect known to be the 2 min. The correlation coefficient (r) between BIS and OAA/S was 0.84 on average, suggesting the BIS as an good subjective indicator of optimal hypnosis for anesthesia induction. Vital signs were stable in all groups. Hypnotic ED50 and ED95 were 0.12 and 0.19 mg/kg, respectively. CONCLUSIONS: Bispectral index can be a useful tool for estimating the optimal hypnosis for anesthesia induction. Hypnotic ED50 of etomidate was 0.12 mg/kg.

A 73-year-old woman with chronic hepatitis C was hospitalized with proximal muscle weakness and generalized muscle pain. The patient was diagnosed as rhabdomyolysis with myoglobinuric acute renal failure. But there was no history of muscle compression, ingestion of drugs which can cause rhabdomyolysis, or alcohol abuse. The initial clinical features and laboratory findings showed no evidence of infectious myopathy or electrolyte abnormality. The electromyography and muscle biopsy was performed and polymyositis was diagnosed. Polymyositis, an idiopathic inflammatory myopathy, can cause rhabdomyolysis, but myoglobinuric acute renal failure due to polymyositis is very rare. We report a case of myoglobinuric acute renal failure caused by polymyositis with review of the literatures.
