The author analysed foreign body in the airway, divided into two groups vegetable foreign body group(VFBG) and non-vegetable foreign body group(N-VFBG), according to the nature, in 88 patients aged from 5 months to 15 years who were diagnosed and treated under ventilating bronchos-copy at Department of Pediatrics and Otolaryngology, Pusan National University Hospital from 1980 to 1990. Of the 88 patients analysed, 13 were followed for review, which comprised clinical assessment, chest radiography, and perfusion lung scan. The follwing results were obtained. 1) The highest incidence was seen in the age group of 1 to 3 years old especially in VFBG, bur no difference in incidence among each age group was observed in N-VFBG, The ratio of incidence between male to female was 2:1 ein total and, in N-VFBG, the incidence of male 8 times higher than female. 2) A wide variety of foreign bodies was recovered, with peanut being by far the most common (50%) and the ratio of incidence between VFBG and N-VFBG was 6 to 4. 3) The time interval of less than 24 hours between aspiration and admission was most frequently seen in 38% and of more than 3 weeks in 11%. The time interval in VFBG and the group with left bronchial lodging was longer than of N-VFBG and the group with right bronchial lodging, each respectively but no statistical difference was observed. The time interval in the group with bronchial lodging was significantly longer than of the group with laryngeal and tracheal lodging. 4) Frequent symptoms and signs were coughing, dyspnea, fever, decreased air entry, coarse breathing sound and rales. In total, clinical manifestations were more common in VFBG, especially in the incidence of fever, decreased air entry, coarse breathing sound and rhonchi. 5) The roentgenographic findings on admission were emphysema, pneumonia and atelectasis in the order of frequency. The incidence of emphysema and complex roentgenographic findings were more common in VFBG whereas in N-VFBG radioopaque foreign body normal roentgenographic findings were more common. 6) The prevalence of bronchial lodging was over 70% regardless of age group. No difference of predilection was observed between right and left bronchial lodging before 7 years old, but after 7 years old right bronchial lodging was significantly seen. 7) The longer the time lag before admission after aspiration, the longer the duration of hospitalization was in VFBG but with no statistical significance. However, no correlation between time lag and the duration o hospitalization was observed in N-VFBG. The group with bronchial lodging had significantly longer duration of hospitalization compare to that of the group with laryngeal and tracheal lodging, The group with left bronchial lodging had longer duration of hospitalization compare to that of the group with right bronchial lodging but with no statical significance. 8) Of the 13 cases reviewed, one had abnormal lung perfusion scan in spite of normal clinical assessment and chest X-ray, who was treated on 20 days days after aspiration of peanut in the right bronchus.

The hydrophobicity assay and DNA probe hybridization assay were compared for analysis of enterotoxigenic Escherichia coli(ETEC), heat-labile enterotoxin(LT) and heat-stable enterotoxin (ST). The ETEC isolated from diarrheal patients were serotyped and investigated for the presence of colonization factor antigens CFA/1, CFA/II, CFA/III and CFA/IV with the expression of mannose-resistant hemagglutination(MRHA) and the levels of surface hydrophobicity. The following results were obtained. 1. Out of these 48 strains, 34 strains were found to be positive for LT production by DNA probe hybridization assay. Out of 34 strains, 1 strain was ST producer, 25 strains were LT producers, and 8 strains were produced both ST+LT producers by DNA probe hybridization assay. 2. Out of 34 strains of positive DNA probe hybridization test, 31 strains was positive in the hydrophobicity test. Among strains of positive hydrophobicity test, 20, 1, and 7 strains produced only LT, only ST and both ST-LT, respectively. Screening efficiency for identifying ETEC by salting out test was 82.4% in sensitivity and 78.6% in specificity. For ETEC detection, the hydrophobicity assay was the least sensitive but was simple, rapid and a good substitute for the DNA probe hybridization assay. 4. CFAs were identified in 43.8% of ETEC strains; 2.1% of the CFAs strains with CFAs harbored CFA/I, 29.2% carried CFA/II, 16.7% carried CFA/III and CFA/IV. And 35.4% expressed none of these CFAs. CFA/I was found in ETEC of serotype 0128: K67, CFA/II was 0128: K67, 0142: K+ and 0159: K+, CFA/III was 086a: K15 and 0128: K67, CFA/IV was 0 86a: K15, 0128: K67, 0125: K70 and 0148: K+.

Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.

We have experienced automated and computerized perimetry using a Humphrey Field Analyzer in our Glaucoma Services. To evaluate its clinical efficacy, we report the results of the Armaly central field screening test in comparison with those of central 30-2 threshold test of the Humphrey Field Analyzer. One hundred fortythree eyes of 83 cases of normotensives, ocular hypertensives and glaucoma patients with open-angle or narrow-angle were enrolled in this study. Fiftyfour out of 61 patients (88.5%) and 73 out of 81 eyes (90.1 %) with visual field defect were detected by the screening test of the Humphrey Field Analyzer. Eight out of 81 eyes (9.9%) with visual field defect detected by the screening test were confirmed as false positive. All points of false positive were solitary, which tended to occur more frequently on superior vusual field. False negative of 8 eyes (12.9%) detected by the screening test were confirmed by the threshold test. The point of false negative was more frequent on superior field and showed to locate more peripherally from the fixation point. There was no significant difference in either central sensitivity or age of the false ring.

Six patients with exfoliation syndrome were seen in our glaucoma clinic. Four patients presented unilateral ocular involvement and the other 2 patients were bilaterally involved. Eight eyes had exfoliation material on the anterior surface of the lens and pupillary border, and 7 eyes exhibited it on the anterior chamber angle. Sampaolesi`s line was detected in 4 eyes. Five patients (6 eyes) of 6 patients (8 eyes) with exfoliation exhbited an elevated intraocular pressure (IOP) exceeding 21 mmHg. Among them, 3 patients (3 eyes) had an extremely high maximum IOP over 47 mmHg, and 2 patients (3 eyes) had a slightly elevated IOP less than 26 mmHg during the follow-up period. Argon laser trabeculoplasty (ALT) was performed twice on each unilateral eye of the 2 patients on whom the inital trabeculectomy failed. However, longterm IOP control after laser treatment was not obtained in either case, which might be due to the extremely high prelaser lOP level, in exoess of 40 mmHg.

The first comprehensive clinical description of exfoliation syndrome was published by Vogt. The appearance is described as a deposition of white granular fluffy material on the anterior lens surface, pupil margin, zonule, ciliary body and anterior chamber angle, and floating free in the aqueous. At past, this syndrome was thought to be rare outside of the Scandinavian countries, but the relatively high prevalence has been noted in many other countries outside of Scandinavia. The clinical significance of this syndrome is high frequency of glaucoma. Six cases in this report illustrate some of typical clinical features of exfoliation syndrome. The purpose of this study is to concentrate our attention upon the presence of this syndrome in Korea.

To determine the effect of apraclonidine hydrochloride on the acute intraocular pressure (IOP) rise after argon laser iridotomy (ALI), a double-masked comparative study was carried out. Twenty-nine eyes (20 patients) with angle-closure glaucoma underwent ALI. Eighteen eyes were treated with apraclonidine, and the remainder received a placebo 1 hour before and immediately after ALI. The mean IOP increase in the apraclonidine group was lower than that in the placebo group at each postlaser interval (p < 0.01). Although the average value of the maximal increases of IOP after ALI in the apraclonidine group was 4 mmHg, that in the placebo group was 16 mmHg. In the placebo group, 27.3% (3 out of 11 eyes) experienced an IOP rise > or = 10 mmHg. However, that kind of IOP rise was not found in the apraclonidine group (0 out of 18 eyes) (p < 0.01). Ocular or systemic side effects were not found in a series of examinations in both groups. Therefore, apraclonidine proved to be effective in lowering the IOP rise after ALI.
