A analysis was performed on 1716 pediatric surgical patients, who were supposed to receive elective operations at Seoul National University Childrens Hospital from March 2, 1991 to June 29, 1991. The results can be summarized as follows; 1) Overall cancelled ratio was 19.6%. 2) Departmental distribution of delayed/cancelled elective operations, Plastic surgery 27.0%, pediatric surgery 26.1%, neurosurgery 20.3%, cardiothoracic surgery 18.1%, orthopedic surgery 18.0%, ENT 15.6 ophthalmology 13.9% and urology 13.8%. 3) Major causes of delay/cancellation of elective operatios; Abnormal history and physical examination 54.3 , non-medical 35.0% and abnormal laboratory data only 10.7%. 4) Detailed causative factors of delay/cancellation of elective operations, URI 30.6%, notadmitted 27.9%, heavy schedule 5.9%, abnormal LFT 5.3%, FUO 4.2%, abnormal PTT/PT 2.4%, arrhythmia and cardiac disease 2.4% and further diagnostic evaluation needed 1.8%.

Disseminated superficial porokeratosis (DSP) is a rare variant of porokeratosis, which is characterized histologically by cornoid lamella and clinically by central atrophy with elevated borders. DSP is usually associated with immunosuppressive states and hematopoietic malignancies, but rarely with malignancies of visceral organs. A 65-year-old male presented with numerous brownish macules with elevated borders on the trunk and limbs that had been present for 1 year. Before the visit to our clinic, gastric cancer was diagnosed at about the same time the skin lesions suddenly increased in size and number. Clinical and histopathological examination revealed that the lesions were consistent with DSP. We herein report a rare case of disseminated superficial porokeratosis that occurred in association with gastric cancer.

The reason for undertaking a special study of pediatric anesthesia is that children and especially infants differ sharply from adult patients. We know the important factors are psychogenic, anatomic, pharmacologic, physiologic and pathologic differences. Although the most apparent contrast in the neonate is his size, immature enzymatic activity probably could prove a greater problem to an uninformed anesthetist. So it seems worthwhile for us to analyze our past pediatric anesthetic experiences(8,600 cases) from 1970 to 1979. The following was obtained from this clinical analysis. 1) Total number of pediatric anesthesias given has been increasing year by year, especially under the age of one year. 2) General inhalation anesthesia has shown increasing numbers, but spinal anesthesia has been decreasing in numbers. 3) Flammable agents such as cyclopropane and ether was disappeared completely from our operating theater in spite of their excellent qualities. However, balanced anesthesia with Innovar has been increase. 4) Pediatric cardiac patients among 8,600 cases have sharply increased from 0.5% in 1970 to 4.7% in 1975 and 11.6% in 1979.

PURPOSE: To evaluate the axial displacement of implant-abutment assembly after cyclic loading in internal tapered connection system. MATERIALS AND METHODS: External butt-joint connection implant and internal tapered connection implant were connected with three types of abutment for cement-retained prostheses, i.e. external type abutment (Ext group), internal tapered 1-piece abutment (Int-1 group), and internal tapered 2-piece abutment (Int-2 group). For each group, 7 implants and abutments were used. The implantabutments assemblies were clamped into the implant holder for vertical loads. A dynamic cyclic loading was applied for 150 +/- 10 N at a frequency of 4 Hz. The amount of axial displacement of the abutment into the implant was calculated at each cycle of 0, 5, 10, 50, 100, 1,000, 5,000, and 10,000. A repeated measures analysis of variance (ANOVA) for the overall effect of cyclic loading and the pattern analysis by linear mixed model were used for statistical analysis. Differences at P<.05 were considered statistically significant. RESULTS: The mean axial displacement after 10,000 cycles were 0.714 +/- 0.488 microm in Ext group, 5.286 +/- 1.604 microm in Int-1 group, and 11.429 +/- 1.902 microm in Int-2 group. In the pattern analysis, Int-1 and Int-2 group showed continuous axial displacement at 10,000 cycles. There was no declining pattern of axial displacement in the Ext group. CONCLUSION: The pattern of linear mixed model in Ext group showed no axial displacement. There were continuous axial displacements in abutment-implant assemblies in the Int-1 and Int-2 group at 10,000 cycles. More axial displacement was found in Int-2 group than in Int-1 group.

Aniridia or iridremis is a Clinical term denoting absence of the iris in whole or in part. Actually, total absence has not been reported, as there has been rudimentary iris tissue in all cases reported in the literature. Because of its extra ordinary propensities as a dominant characteristic, occasionally an irregular dominant, and because of its stricking appearance which facilitates investigation, it has received extensive study by geneticists. Indeed, so interesting are its hereditary and pathologic aspects that these have received for more attention that have therapeutic measures for aniridic cases. I have experienced a case of aniridic family, a 40 years old women and her two sons, without other disturbances during their life saving, except poor vision, which was not significant of in correction for visual acuity.

The arterial and venous differences of thiopental. pharmacokinetics and its impact on the onset of pharmacologic effect were examined in 6 male surgical patients with normal renal and hepatic functions during short time period of 6hrs post-intravenous bolus injection over 5 second(5 mg/kg). Arterial and venous blood samples were withdrawn from radial artery and subclavian vein, respectively at the time of right before and after injection(0), 5, 10, 20, 30, 45 (sec), l, 2, 5, 10, 30(min), 1, 2, 3, 4, 5, 6(hrs). Serum concentrations of thiopental were determined by reverse-phase, high performance liquid chromatography and the clinical endpoint of anesthesia induction were interpreted as the time of loss of consciousness by observing spontaneous closing of eyes and loss of eyelash reflex. As the results, significant differences between arterial and venous concentrations were noted during early phase lasting up to 10 minutes. Arterial data was best fitted to tri-exponential decay model. In analysing pharmacokinetic parameters with serum data of 6 hrs duration, there were no significant differences in AUCo-(area under curve), AUCO-t, and clearance(P <0.05), but significant difference in peak concentrations(arterial: 103.97+/-12.15, venons:17.487+/-5.206ug/ml), and times to peak(arterial: 0.67+/-0.037, venous: 1.653+/-0.712min), AUMC O-t, MRT (mean residence time), apparent T 1/2(terminal half-life) and apparent Vdss(steady-state volume of distribution). Spontaneous eye closures were observed within 20 seconds(10-20sec) after the end of injection where arterial concentrations were at peak(n=3) or right after peak(n=3) and otherwise, venous concentrations were at low or even almost at zero(n=3), reflecting the fact that arterial eoncentrations are directly correlated to the clinical efficacy and more important in pharmaco-kinetic and dynamic aspect of drug.
