Partial knee ankylosis is a recognized complication following open operative procedure, trauma and disease processes about the knee. It can result from the formation of intraarticular adhesion and contracture of the capsule as well as the shortening or adhesion of the quadriceps mechanism. Physical therspy and occasionally manipulation under the anesthesia may improve the results, but performed late, these methods will be useless. This is a review of 30 patients who had severe limitation of motion in the knee joint following open operative procedures or trauma about the knee and who were treated by the percutaneous release of adhesions under the arthroscopic control. The following results were obtained; There were 17 males and 13 females, and the age of release ranged from 23 to 69 years old (av. 42.8years old). The interval between arthroscopic adhesiolysis and the last follow-up evaluation ranged from 6 months to 5 years and 7 months(av. 23 months). The interval between the last open operative procedure or trauma and arthroscopic adhesiolysis ranged from 3 months to 4 years(av. 15 months). The average preoperative knee ROM was 38.8°the postoperative ROM was 121.1°and the average final knee ROM at follow-up was 102.6°So the average loss of ROM was 18.5°The arthroscopic adhesiolysis seems to be applied to the various conditions of the partial knee ankylosis and the results are better than the other surgical procedures when it was performed early enough.

This is to report the technique of reversed iliac leg stent-graft in endovascular treatment for isolated internal iliac artery (IIA) aneurysm, which had significant size discrepancy between the common iliac artery (CIA) and external iliac artery (EIA) in 3 patients from different hospitals. Three patients were a 85- and two 82-year-old men. Treated were right IIA aneurysms, sized 6.5x6.2 cm, 5.0x4.0 cm, and 4.1 cm in longest diameter, respectively. The diameters of the right CIA and right EIA measured 21 mm/11 mm, 15 mm/11 mm, and 20 mm/10 mm, respectively. In all cases, reversed iliac leg stent-grafts were prepared on-site; unsheathed and mounted upside-down manually, and deployed in each right CIA. Post-stent-graft angiograms showed complete exclusion of the aneurysms, except for minimal type 1 endoleak in one case. This technique is a useful treatment option in patients with isolated IIA aneurysm.

To evaluate left ventricular diastolic function in patients with coronary artery disease, gate radionuclide ventriculography was performed prospectively in 42 patients who were admitted to Seoul National University Hospital from November 1985 to August 1986 because of anterior chest pain. All patients had no valvular heart disease, congenital heart disease, cardiomyopathy and arrhythmia, and no abnormal vall motion in gated nuclide ventriculography and contrast left ventriculography. 25 patients with more than 50% of stenosis in coronary arteriography were compared with 17 control subjects without stenosis. The following results were obtained; 1) There were no significant differences between normal controls and patients with coronary artery disease in the analysis of the parameters of the left ventricular systolic function, such as ejection fraction (EF), peak ejection rate (PER), time to peak ejection rate (TPER) and ejection time (TES, TES/BCL). 2) Same results were found with those of the left vnetricular diastolic function, such as peak filling rate (PFR), diastolic time interval (DTI, DTI/BCL), rapid diastolic filling interval and time to late diastolic filling (TLDF). 3) The percent contribution of late diastolic filling to stroke volume (%LDF/SV) was more increased in patients with coronary artery disease than the normal control subjects (38.2+/-12.4% vs 28.3+/-7.8%, P<0.01). 4) As the results of above, it can be concluded that the percent contribution of late diastolic filling to stroke volume (%LDF/SV) obtained by using the non-invasive method of gated radionuclide ventriculography can be a sensitive parameter for early evaluation of the left ventricular diastolic dysfunction in coronary artery disease.

BACKGROUND: Multi-drug resistant (MDR) Acinetobacter baumannii has emerged as a significant infectious agent in hospitals worldwide. The purpose of this study was to determine the molecular characterization of MDR A. baumannii clinical isolates. METHODS: Two hundred eighty-five strains of non-duplicated A. baumannii collected from March to November 2011 from a university hospital laboratory located in the Wonju area of the Gangwon province of Korea were analyzed for MDR genes. RESULTS: All of the 285 imipenem-resistant A. baumannii isolates were encoded by a blaOXA-23-like gene, and all isolates with the blaOXA-23-like gene had the upstream element ISAba1. The 16S rRNA methylase gene armA was detected in 153 (50.2%) clinical isolates, but rmtA, rmtB, rmtC, rmtD and npmA were not detected in any isolates in the present study. The gene encoding aac(6')-Ib was the most prevalent aminoglycoside-modifying enzyme. The sequencing data for the quinolone resistance-determining region of gyrA and parC revealed the presence of Ser (TCA) 83 to Leu (TTA) and Ser (TCG) 80 to Leu (TTG) substitutions. All but one of the 285 A. baumannii isolates showed similar band patterns on repetitive extragenic palindromic-PCR profiles. CONCLUSION: The molecular characteristics of the resistance genes of MDR A. baumannii isolates obtained from the Wonju area of Gangwon province were similar to those of other areas in Korea.

BACKGROUND: Tracheal intubation can cause sympathetic stimulation such as hypertension and tachycardia. Many drug are used for reducing the incidence of hypertension and tachycardia induced by intubation. Among these drugs, fentanyl can be used with good result. The purpose of this study was to find the appropriate fentanyl injection time before intubation when a small dose (3 microgram/kg) was used. METHODS: We studied 82 ASA class 1 2 patients, scheduled for gynecological elective surgery, randomized into 5 groups. Group 1 received no fentanyl before intubation, and groups 2, 3, 4 and 5 received 3 microgram/kg fentanyl at 7 min, 5 min, 3 min and 1 min before intubation, respectively. The blood pressure and heart rate were checked at preinduction and post-intubation periods for 5 minutes. RESULTS: The increase of the heart rate was significantly lower in groups 2 and 3 than in group 5 just after intubation. Furthermore the increase of the mean blood pressure was significantly lower in groups 2, 3 and 4 than in group 5 just after intubation. The incidence of tachycardia and hypertension was significantly lower in groups 2, 3 and 4 than in group 5 just after intubation. CONCLUSIONS: When a small dose of fentanyl was used to blunt the intubation induced sympathetic stimulation, the appropriate time was prior to 3 minutes before intubation.

BACKGROUND: Sevoflurane, desflurane, and propofol are widely used in pediatric anesthesia because of their rapid recovery. However, emergence agitation is more reported with sevoflurane or desflurane than with propofol. Our clinical experience indicates emergence agitation with propofol is also frequent. We tested the hypothesis that depth of anesthesia could lead to frequent emergence agitation with propofol. METHODS: Sixty children, ASA 1, aged 3-12 years, undergoing general anesthesia for adenotonsillectomy were randomized to receive maintenance anesthesia with sevoflurane, desflurane, or propofol. The bispectral index was monitored and maintained within 40-65. Time to extubation, duration of postanesthetic care units stay, bispectral index just before stopping the anesthetic agent, anesthetic time, early and late postoperative Pediatric Anesthesia Emergence Delirium Scale (PAEDS), and Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) were compared among the 3 groups. Data were analyzed using ANOVA (demographic data, measured time interval, BIS) and Kruskal-Wallis test (PAEDS and CHEOPS). The Spearman correlation coefficient was used to confirm the correlation between the two scales. RESULTS: Although desflurane resulted in the fastest extubation, other scales were not statistically different. PAEDS and CHEOPS for sevoflurane showed a positive correlation in the early recovery period, but desflurane and propofol did not. CONCLUSIONS: With the same depth of anesthesia, emergence agitation among desflurane, sevoflurane, and propofol was not different in children.

BACKGROUND: The p38 mitogen-activated protein kinases (p38Map kinases) are a family of prolinedirected serine/threonine kinases. At least four isoforms of p38Map kinases have been identified; however, their physiological significances remain to be understood. Recently, the role of p38Map kinase in insulin-stimulated glucose uptake has been suggested. The present study aimed to investigate which isoform(s) were responsive to insulin stimulation. In addition, the activities of p38 Map kinase isoforms that may participate in the insulin's antiapoptotic function in CHO-IR cells were also determined. METHODS: Chinese hamster ovary cells, expressing wild- or mutated human insulin receptors (CHO-IR cells), were used to investigate whether insulin can stimulate any of the isoform(s) of the p38Map kinases. The p38Map kinase activity was determined by measuring the degree of 32P-labelling of ATF-2 protein, a specific substrate of p38Map kinase. A DNA laddering assay was performed to examine the degree of apoptosis and a RT-PCR analysis to determine which isoform(s) of the p38Map kinases were expressed in response to insulin. RESULTS: p38Map kinase activation by insulin was sharply suppressed in only the CHO-IR/A1018K cells, which lack the intrinsic tyrosine kinase activity of insulin receptors. Insulin stimulation of p38Map kinase was insensitive to SB203580, an inhibitor of the alpha(alpha)-and beta(beta)-isoforms of p38Map kinases. Moreover, orthovanadate, known as a specific stimulator of the gamma(gamma)-and delta(delta-) isoforms, stimulated the p38Map kinase activity in CHO-IR cells. Insulin increased the degree of mRNA expression of the delta-isoform, but not that of the alpha-isoform p38Map kinase. Interestingly, PD98059, an inhibitor of ERK, suppressed p38Map kinase stimulation, as well as the antiapoptotic protection of cells by insulin. As insulin was found to still protect ERK-lacking cells (CHO-IR/ SOS) from apoptosis, any substantial role(s) of ERK might be excluded. CONCLUSION: Our data suggest that insulin may stimulate the activity and expression of the-isoform of p38Map kinase in a MEK1/2-dependent manner. The involvement of the delta-isoform of p38Map kinase in insulin's antiapoptotic protection was also suggested, but remains to be investigated further to clarify the nature of its mechanism of action
