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: The median effective dose, ED(50), of rocuronium bromide for inserting the laryngeal mask airway (LMA) in children was not known. The purpose of this study was to determine the clinical ED(50) (cED(50): median value of rocuronium dose of 6 set of crossing success and failure by Dixon's up-and-down method) of rocuronium to insert a LMA in pediatric patients. METHODS: Children aged 2 to 12 years (n = 21) and scheduled for urologic, orthopedic, plastic or ophthalmic surgery lasting less than 2 hr under general anesthesia were enrolled in this study. After applying a standard cardiorespiratory monitor, all patients received thiopental sodium 5 mg/kg for induction of anesthesia. Insertion of LMA was attempted 90 seconds after administration of rocuronium and manual ventilation with 8 vol% of sevoflurane. We recorded the movement of patients, blood pressure and heart rate. The initial dose of rocuronium was 0.3 mg/kg, and in accordance with Dixon's up-and-down method, the rocuronium concentration for consecutive patients in each patient was varied with increments or decrements of 0.05 mg/kg based on the result of previous patient. RESULTS: The cED(50) of rocuronium required to insert a LMA was 0.09 mg/kg with 8 vol% sevoflurane. With isotonic regression, cED95 of rocuronium was 0.13 mg/kg (95% confidence intervals 0.096-0.14 mg/kg). CONCLUSIONS: This study demonstrated that the cED(50) and cED(95) of rocuronium were 0.09 mg/kg and 0.13 mg/kg in children respectively. It provides satisfactory conditions for LMA insertion in anesthetized children and decreases the excessive hemodynamic change.

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.

A 44-year-old man, who had a history of myocardial infarction (MI) due to thrombotic occlusion of right coronary artery (RCA) aneurysm, visited emergency department presenting with ST-segment elevation myocardial infarction (STEMI). The patient had been on oral anticoagulant therapy (warfarin) from the first thrombotic event, but the medication had been recently changed to aspirin 4 months before the second event. Emergent coronary angiography revealed thrombotic total occlusion of RCA with heavy thrombotic burden from middle RCA to the ostium of the posterior descending branch. Combination pharmacotherapy was performed with anticoagulants (heparin), fibrinolytics (urokinase), and Glycoprotein IIb/IIIa antagonists (abciximab), in addition to mechanical thrombosuction. However, on hospital day 2, the patient complained recurrent chest pain and again underwent coronary angiography, which revealed distal embolization of large thrombus to the posterior lateral branch. Coronary flow was recovered after repeated mechanical thrombosuction was performed. This case has shown the importance of aggressive combination drug therapy, accompanied by mechanical thrombosuction in patient with myocardial infarction due to thrombotic occlusion of coronary artery aneurysm and the importance of unceasing life-long anticoagulant therapy in those particular patients.

Skeletal muscle involvement has been well documented and muscular symptoms are common in patients with polyarteritis nodosa (PAN). However, the level of muscle enzyme is uncommonly elevated and overt rhabdomyolysis is very rare. We report a case of PAN presenting as rhabdomyolysis. A 22-year-old man was admitted because of fever, severe myalgia and swelling in all extremities. Laboratory investigations showed markedly increased levels of serum creatine kinase and myoglobin. There was diffusely increased muscular uptake in bone scan. Muscle biopsy from the right deltoid revealed vasculitis involving medium-sized vessel with ischemic necrosis of muscle. On angiography, saccular aneurysms were found in multiple arterities. Therapy with methylprednisolone pulse therapy and cyclophosphamide was followed by improvement of his symptoms.
