Tono-pne and Perkins tonometer have been widely accepted to measure the intraocular pressure(IOP) of children under the general anesthesia because of their portability. We evaluated the difference of IOP between two devices and the IOP variability in 39 children(77 eyes) under age 13 who had undergone surgery for strabismus or entropin under the general anesthesia. One observer measured the IOP three times alternately, and the order of measurement was randomized. Only 5% of Tono-pens coefficient of variance was considered valuable. The range of Tono-pen IOPs was 9~22mmHg, and the average was 15.41+/-3.23mmHg. The range of Perkins IOPs was 4~20 mmHg, with the average of 12.47+/-3.31mmHg. The difference between two methods on average was 2.94mmHg. Tono-pen IOPs were significantly greater than those recorded by Perkins tonometer, but both were within normal range. The IOP variability was not significantly different between two devices. Therefore both methods can be applied effectively in a clinical setting after sedation or general anesthesia of uncooperative children.

Tear film consists of lipid layer, aqueous layer, and mucinous layer, and it acts as protection of cornea, nutritional supply, and refraction. The assumption of this study is that the use of contact lens may induce the rapid drainage of tear film, and may make it become thin, and may affect the function of corneal epithelium, and may induce several complication. The author analysed 168 volunteers of medical students. The volunteers consisted of junior and senior grades in Ewha Womans University were classified into two groups. One group was the users of contact lenses(70), and the other group was non-users of contacts lenses who have not any other ocular problems control group(98). The purpose of this study was to evaluate the influence of tear secretion in fitting contact lens. The results were as follows; 1. Mean value and standard deviation of Schirmer test showed; contact lens group was 20.5 +/- 8.0mm/5min, and control group was 21.2 +/- 8.2mm/5min. There was no statistical significance between two groups. 2. The author could not obtain the statistical difference the users of soft contact lenses and the users of hard contact lenses, because the number of the users of hard contact lenses was so small in contrast to that of the users of soft contact lenses. 3. There was no significant correlation between daily wearing time and the result of Schimer test. 4. The correlation between the wearing period of contact lens and the result of Schirmer test showed; the longer wearing period of contact lens was, the longer wetting length of Schirmer test paper was, but it was not statistically significant. The authors concluded that the use of contact lens does not affect the secretion of tear.

The authors have been developed a menu-driven FoxBASE system for surgical pathology reporting and automatic encoding in Systematized Nomenclature of Medicine. The system requires no prior knowledge of FoxBASE and is readily installed on any IBM or it's compatible personal computer. Working sheet generation is automatically accompanied by data from previous cases on the same patient. Important data which include patient name, age, sex, surgical number, hospital unit number and encoded diagnoses, are stored on the hard disk permanently; complete reports are saved on floppy diskettes. Cases can be retrieved by patient name, surgical number, hospital unit number and SNOMED codes within 0.1 second. Daily work lists and listings of incomplete cases are easily obtained. This FoxBASE system has been in use for 1 year and 6 months and resulted in increased efficiency of retrieval and gathering of basic information for specific study, cost effectiveness, markedly diminished workload of typist and very short wasting time during complete restoration of data file for hard disk failure.

We analysed retrospectively pharmacokinetic parameters of gentamicin and amikacin in 44 and 58 Korean pediatric patients, respectively, with normal renal function. Pharmacokinetic parameters were calculated from two concentrations in serum by method of Sawchuck. There was wide individual variation in peak serum concentrations of gentamicin and amikacin, Administration of the usually recommended doses yielded subtherapeutic concentrations in 47% and 82%, respectevely, of patients in the peak concentrations of gentamicin and amikacin. The volumes of distribution of gentamicin and amikacin in children of over 1 year of age were 0.37+/-0.13L/kg and 0.41+/-0.13L/kg which are greater than those reported from the western countries. We conclude that the wide individual variation and high frequency of subtherapeutic levels in the peak concentrations of gentamicin and amikacin obtained by usually recommended dosage as well as the narrow safety margin of these drugs necessitate monitoring of serum concentration and adjustment of individual dosage regimen early in the course of treatment with aminoglycosides.

PURPOSE: We compared CT findings of thickened wall-type gallbladder cancer with those of complicated cholecystitis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of ten patients with thickened wall-type gallbladder cancer and eight patients with complicated cholecystitis, from March 1991 to November 1995. RESULTS: CT findings of thickened wall-type gallbladder cancer showed diffuse or focal wallthickening. Wall thickness was 5.3-18.0 mm(mean value, 12.2mm ; n=10). Gallbladder wall thickness of complicatedcholecystitis was 3.0-14.0mm (mean value, 6.6mm ; n=8). Statistical significance was noted between thickened wall-type gallbladder cancer and complicated cholecytitis(p<0.0029). Irregular wall thickening was noted in 7/10cases of thickened wall-type gallbladder cancer(70%). Regular wall thickening was noted in 6/8 cases of complicated cholecystitis(75%). The luminal diameter of thickened wall-type gallbladder cancer was 3.3-5.4cm (meanvalue, 4.2cm ; n=10). The luminal diameter of complicated cholecystitis was 5.2-8.0cm (mean value, 6.5cm ; n=8).Statistical significance was noted between thickened wall-type gallbladder cancer and complicated cholecystitis(p<0.0003). The halo sign was noted in only 3/8 cases of complicated cholecystitis(38%). Secondary findings of thickened wall-type gallbladder caner was lymphadenopathy in 3/10 cases(30%), and liver invasion in 2/10 cases(20%). Secondary findings of complicated cholecystitis were liver abscess in 2/8 cases(25%), and RLQ abdominal fluid collection and pleural effusion in 4/8 cases(50%). CONCLUSION: Differential factors of thickened wall-type gallbladder cancer from complicated cholecystits are gallbladder wall thickness, regularity of wall thickness, halo sign, secondary findings and luminal distention.

Right intrathoracic stomach associated with organoaxial torsion is a rare form of congenital hiatal hernia. We report the radiologic findings in two cases of complete or partial right intrathoracic stomach secondary to congenital hiatal hernia. The barium meal test demonstrated the presence of complete or partial right intrathoracic stomach and non-obstructive organoaxial torsion with the greater curvature lying against the right chest wall. The esophagogastric junction was located above the diaphragm. CT revealed a cystic mass in the right posterior mediastinum. This cystic lesion should be differentiated from other congenital mediastinal cysts.
