In postanesthetic period, infants and children have a risk of hypoxemia due to decreased functional residual capacity(FRC) and increased alveolar-arterial O2 tension gradient(A-a DO2). We measured arterial oxygen saturation(SaO2) with a pulse oximeter in 60 ASA class 1 infants and children. Group 1 was breathing with supplemental oxygen(4L/min) by mask and Group 2 was breathing with room air in recovery room after general anesthesia. SaO2 was measured on arrival in the recovery room, 2,4,6, 8,10,15, and 20 minute after arrival The results were as follows: 1) Postanesthetic SaO2 measured on arrival in the recovery room had decreased significantly(p<0.05) to preanesthetic SaO2 2) SaO2 measured in room air had decreased significantly compared with SaO measured in supplemental oxygen. As a result of the study, it is thought to be safe that supplemental oxygen is administered to patient on transfer and in recovery room.

Displaced intra-articular fractures of the calcaneus result in serious and prolonged disability. These injuries continue to pose a therapeutic challange and there remains a great deal of controversy regarding treatment, operative versus nonperative. The lateral approach for open reduction, popularized by Palmer, has been used by many authors, with high percentage of excellent results. We treated 21 displaced intra-articular fractures of the calvaneus in 18 patients by open reduction and internal fixation through the lateral approach from July 1990 to May 1992 and the patients have been followed from 12 to 36 months from the time of their injury. The clinical and radiographic analyses were as follows; 1. The most common cause of injury was falls from a height: 19 fractures in 16 patients(88.8%), Spine fracture was most commonly associated injury : 5 patients (27.8%). 2. Fracture was classified according to classification of Paley and Hall. Eight fractures were tongue type(no comminution 4, with comminution 4), 12 joint depression type(no comminution 8, with comminution 4), and a comminuted type. 3. The average bohler tuber-joint angle was

In cases of L4-5 spinal fusions, L5-S1 segment used to be included in the fusion traditionally for fear of progressive deterioration of the lumbosacral motion segment after fusion above. The purpose of this study was to evaluate the advisability of extension to L5-S1 segment in cases of L4-5 fusion for an isolated pathologic condition in L4-5 sement. A retrospective review of 72 patients with spinal fusion for an isolated pathologic condition in L4-5 segment was undertaken to compare the clinical results and adverse effects in two groups. One group consisted of 39 patients with floating L4-5 fusion(SF), and the other group consisted of 33 patients with L4-S1 fusion(LSF). The age, pathologic condition at L4-5, and the fusion method(lateral fusion) were matched in two groups. The mean follow-up period was 43.6 months(ranging 24-69 months). Comparisons were made for operative problems, post-operative complications, the amount of changes in angular motion at the adjacent segments to fusion at the last follow-up compared to the pre-operative motion, and the clinical results of treatment. The LSF group took 38 more minutes and lost 245 grams of more blood in averages to complete the additional surgical procedures compared with those in SF group. Several considerable post-operative complications were one deep infection in SF group and three metal failures of sacral fixation with subsequent two fusion failures in LSF group which were mostly concerned with the sacral fixations. The changes of angular motion at follow up compared to pre-operative motion in SF group were 1.5° gain in average (ranging 3° loss-6° gain) in L3-4 segment and 0.6° gain in average (ranging 5° loss-5° gain) in the L5-S1 segment. Those in L3-4 segment of LSF were 2.8° gain in average (ranging 2°-loss 9° gain). Therefore the higher stress and subsequent degeneration are more likely expected above the L4-S1 fusion rather than below the L4-5 fusion. The satisfactory clinical results were 89.7% in SF group and 87.9% in LSF group without significant difference between two groups. In conclusion there is no need to include the L5-S1 segment in the L4-5 fusion when the pathology is limited to L4-5 segment.

PURPOSE: Bronchial asthma is a disorder that is characteized by symptoms of reversible airway obstruction and increased responsiveness of the bronchus and to quantify the degree of br onchial hyperresponsivenes can be very helpful in determing the severity of disease and the prognosis. But the Methacholine provocation test is not always easy to be performed in all patients. Thus we designed this trial to know the relationship between the degree of bronchial hype rresponsiveness by Methacholine and the severity of asthma symptoms, pulmonary function te st and atopic findings. METHODS: Methacholine provocation test was performed on 60 clinically stable asthma patients who visited the pediatric allergy clinic of Taegu Fatima Hospital from July, 1992 to June, 1 993. All patients were free of URI for at least 6 weeks and medications were withhold for 2 weeks for corticosteroid or beta receptor agonist and at least 2 days for theophylline. All subjects ha d FEV1 more than 70% of predicted value, and more than 20% of reversible obstruction. Disease severity score(DSS) was compared by the number of asthmatic attacts, clinical picture, therapeutic medications and the Airway reactivity score(ARS) was measured on the number of nonspecipic irritants provoking the bronchial hyperresponsivess. Methacholine provocation test was performed as follows; Normal saline was inhaled 5 times by tidal breath through De Vilbiss 646 inhaler and FEV1 was measured as baseline. According to Chai standardized method, Mathacholine was diluted to 0.075-25mg/ml concentration and inhaled 5 times and accumulated Methacholine was graded 0.375-225.0 Breath Units(One BU = 1 inhalation of 1 mg/ml). PD20 was determined to the concentration at which the FEV1 faIled to 20% below the baseline. RESULTS: 1) PD20 were distributed variably between 0.375 BU and 225.0 BU 2) Bronchial hyperresponsiveness was high on asthma with allergic rhinitis(p<0.05). 3) Bronchial hyperresponsiveness by Methacholine provocation test had significant correlation both DSS(r= -0.473; p<0.01) and ARS(r= -0.32; p<0.05). 4) Bronchial hyperresponsiveness by Methacholine provocation test had significant correlation to baseline FEV1/FVC ratio(r= -0.63; p<0.01). 5) Bronchial hyperresponsiveness by Methacholine provocation test had no statistical significant correlation to serum IgE value(r= -0.24; p<0.05). CONCLUSIONS: The severity of bronchial hyperresponsiveness by Methacholine provocation t est had significant correlation with DSS and ARS, and there was a close relation BHR to the baseline FEV1/FVC1 ratio too. Thus exact history about clinical pictures, medications, provocating irritants in asthmatic patients and baseline FEV1/FVC ratio can be very helpful in assessing the bronchial hyperresponsiveness.

The purpose of this study is to examine the change of enzymeimmuno-assay for prostaglandinE2 in the synovial fluid lavage specimen of patients with mandibular fracture patients without condylar fracture. For this study, fourteen patients (eight males, six females) with mandibular fractures without condylar fracture was investigated to analyse the synovial fluid from upper temporomandibular joint cavities. Synovial fluid was collected from TMJ cavities of mandibular fracture patients before open reduction and after one week of open reduction, and then stored in liquid nitrogen tank after centrifuge. Two synovial fluid lavage samples of TMJs of 2 asymptomatic served as normal controls referred from other data. The concentrations of PGE2 were measured by use of PGE2 EIA system (Amersham). The following results were obtained: 1) In nine patients, the concentrations of PGE2 are lower after open reduction than before. 2) In three patients, the concentrations of PGE2 are higher after open reduction than before. 3) There was no statistical significant between the preoperative group and postoperative 7 days (p>0.05), but there was some difference between the two groups. In conclusion, the results suggest that PGE2 probably does not play as important role in the harm of TMJ.

BACKGROUND/AIMS: Patient compliance and resistance to antibiotics are main factors determining the success of Helicobacter pylori eradication. This study provides basic data to verify the efficacy of currently implemented eradication therapy and reports changes in H. pylori resistance to all antibiotics used at Asan Medical Center, Seoul, Korea from 2004 to 2010. METHODS: We investigated the resistance rates to amoxicillin, clarithromycin, metronidazole, ciprofloxacin, and levofloxacin in 88, 100, and 47 strains isolated from adult patients without H. pylori eradication history in 2004, 2007, and 2010. RESULTS: The resistance rate to amoxicillin increased from 5.0% in 2007 to 10.6% in 2010. The resistance rate to clarithromycin increased from 10.2% in 2004 and 11.0% in 2007 to 14.8% in 2010. However, no difference was observed in the resistance rate to metronidazole, and strains resistant to tetracycline were not detected at all in this study. The resistance rates to quinolone lingered at 15-17% for 3 years. The non-resistant strains to antibiotics accounted for 56% of the total in 2004 and 62% in 2007. In contrast, a decreasing tendency was found for those strains in 2010 (43%). No significant differences were shown in the multi-drug resistance rate or the co-resistance rates of amoxicillin and clarithromycin over the 3 years. CONCLUSIONS: We showed increased resistance rates to clarithromycin and amoxicillin over the last 7 years, aligning with the results of previous studies performed domestically. Efforts are needed to inhibit the increase in resistant bacteria to maintain the effectiveness of eradication therapy.

Sir James Paget described the first case of Paget's disease of the breast in 1874, and Du-breuilh, in 1901, reported the first case of extramammary Paget's disease of the vulva. Paget's disease of vulva is a rare intraepithelial neoplasm of uncertain histogenesis. Recently we expe-rienced a case of Paget's disease of the vulva that we present a brief review of literature.
