BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

PURPOSE: We applied lateral lithotomy position to the severe ureteral stricture cases supposed to fail with only retrograde approach. MATERIAL AND METHODS: From October 1997 to April 1999, 13 patients with severe ureteral stricture (lenghth>2cm or complete obstruction) supposed to fail with only retrograde approach and one patient with study. The causes of ureteral strictures were pelvic malignancy in 5, tuberculosis in 4, trauma in 2 and others in 2. The patient's ipsilateral shoulder was rotated and fixed like lateral position. And ipsilateral pelvis was elevated with sandbag or pad and rotated about 45 degrees, too. The retrograde approach was tried at first, if fail, antegrade approach was combined. RESULTS: We could insert ureteral stent via retrograde approach only in 3 patients and we needed aid of antegrade approach for passage through ureteral stricture in the other 11 patients (79%). Percutaneous antegrade approaches were combined in those 11 patients and we could pass the guide wire and indwell the stent in 10 of 11 patients (91%) using this position. CONCLUSIONS: The lateral lithotomy position was very helpful to the simultaneous retrograde and antegrade approach in severe fibrotic or malignant ureteral strictures.

PURPOSE: To evaluate the effects of wearing rigid gas permeable (RGP) contact lenses on the topographic changes in keratoconus. METHODS: Seventy-seven keratoconic eyes that wore multicurve RGP contact lenses and 30 keratoconic eyes that wore no contact lenses were retrospectively analyzed. The mean follow-ups were 22.6 and 20.5 months in the lens-wearing and control groups, respectively. Visual acuity, comfort, daily wearing time, and corneal staining were evaluated for both groups. The changes in topographic indices were compared between the lens-wearing and control groups. RESULTS: Multicurve RGP lens corrected logarithm of the minimum angle of resolution visual acuity of the lens-wearing group significantly improved from -0.016+/-0.065 to -0.032+/-0.10 at follow-up (p=0.05). In the lens-wearing group with advanced keratoconus, the Sim Kmax, Sim Kmin, apical power, astigmatic index, and anterior elevation significantly decreased from 57.68+/-4.26 diopter (D), 50.50+/-2.32 D, 62.79+/-5.11 D, 7.20+/-0.55 D and 67.36+/-16.30 microm to 55.51+/-4.28 D, 49.62+/-3.26 D, 60.31+/-5.41 D, 5.90+/-0.51 D and 60.61+/-16.09 microm, respectively (paired t-test, p<0.05). The irregularity index of 3 mm did not significantly change. Meanwhile, in the control group, the apical power and irregularity index increased from 55.56+/-7.25 D and 3.06+/-1.68 D to 57.11+/-7.75 D and 3.25+/-1.71 D, respectively (paired t-test, p=0.008, p=0.01). CONCLUSIONS: Properly fitted multicurve RGP contact lenses are not likely to contribute to the progression of keratoconus.

BACKGROUND: Residual pleural thickening is frequently seen following treatment for tuberculous pleurisy, and pleural decortication is performend occasionally in patients with severe residual pleural thickening. However, predictive factors for the development of residual pleural thickening are uncertain at the initial diagnosis of the tuberculous pleurisy. Therefore, the purpose of this study was to identify the associated factors for residual pleural thickening at initial diagnosis. METHODS: We separated 63 patients diagnosed as tuberculous pleurisy into two groups; group 1 consisted of patients without residual pleural thickening and group 2 comprised patients with residual pleural thickening at the end of tuberculous pleurisy treatment. We analyzed the clinical characteristics, radiological findings, pleural biopsy and characteristics of pleural fluid between group 1 and group 2. RESULTS: The study population and clinical symptoms of the two groups were not significantly different and the duration of symptoms before treatment and the peripheral WBC were similar between the two groups. The presence of pulmonary tuberculosis, pleural fluid loculation or the amount of pleural effusion sid not differ significantly between the thwo groups. The incidence of positive AFB staining(group 1 : 8%, group 2 : 38%) and granuloma(group 1 : 30%, group 2 : 62%) on pleural biopsy specimens was significantly higher in group 2 than in group 1. Pleural fluid WBC and differential count, adenosine deaminase level, pH, preotein level or glucose level did not differ between the two groups. However, group 2 had higher LDH levels (1370±208mg/dl) than group 1 (860±71mg/dl, p<0.05). CONCLUSION: In tuberculous pleurisy, patients with residual pleural thickening following treatment demonstrated a higher incidence of posivive AFB staining and granuloma on the pleural biopsy specimens or higher LDH level in the pleural fluid than patients wihtout residual pleural thickening From these results, we speculate that the amonut of tuberculous bacilli and granuloma are probably correlated with residual pleural thickening in the tuberculous pleurisy.
