OBJECTIVES: Over the last 30 years, despite the increasing sophistication in medical care, the mortality of acute renal failure(ARF) has remained virtually unchanged at 40-50%, but the reasons remain unknown. This study intend to identify prognostic risk factors influencing survival and predict the mortality in ARF patients. METHODS: We retrospectively analyzed 152 patients with ARF who required renal replacement therapy, or whose serum creatinine level above 5 mg/dl, from Jan. 1988 to May. 1995. Multiple factors which may influence mortality were evaluated by univariate and multivariate analysis. RESULTS: 1) Of the 152 patients, 97 were male and 55 were female. The mean age was 47 years and the overall mortality was 36.8%. 2) Based on the univariate analysis, age>60 years, cause of ARF, APACHE II score, number of failing organs, peak serum creatinine level, PaO2, coma, hypotension, ARDS, GI bleeding, ventilatory support, need for antiarrhythmics, DIC, cardiovascular failure, pulmonary failure, neurological failure, and gastrointestinal failure were all significant factors discriminating between survivors and nonsurvivors(p<0.05) 3) By multivariate analysis, hypotension, coma, ventilatory support, and age over 60 years were significant independent predictors influencing survival in ARF patients and logistic equation and logit score were as follows : z=-2.04+1.32(age over 60)+2.18(hypotension)+2.88 (ventilatory support) + 3.28(coma) P=ez/(1+ ez) 4) In ROC(receiver-operating characteristic)curve, when the cutoff point was 0.2, maximum sensitivity was 75% and maximum specificity was 82%. CONCLUSION: In ARF, prognostic risk factors for mortality were age over 60 years, hypotension, assisted ventilation and coma. The logit score by multiple analysis is a reliable predictor of mortality in ARF patients, however the further studies are required to confirm these results.

The use of interlocking intramedullary nail is accepted one of treatment choices in the comminuted fractures of humeral shaft. The insertion of distal interlocking screws remains technically problematic. The use of intrageon's hands during the procedure. In order to reduce technical difficulty and radiation exposure, it is necessary to compare the rigidity of intramedullary nail according to the number of distal interlocking screws. The purpose of study is to compare the stability of interlocking intramedullary nail according to the number of distal screws by means of torsional compliance measurements in the simulated humeral shaft fractures. Simulated fractures were made in 20 humora from 10 cadavera at the mid-junction of humeral shaft. All humora were fixated with titaium humeral nail system. Interlocking screws were placed at proximal and distal screw holes by standard procedure. Group I consisted of 10 humora fixated with one distal interlocking screw and group II consisted of 10 humora fixated with two distal intterlocking screws. Torsional compliance was measured with single-end of 10 humora fixated with two distal interlocking screws. Torsional compliance was measured with single-end double arm torquing machine. The torsional compliance analog was 0.0294+/-0.0033 mm/N mm for one screw and 0.0241+/-0.0045 mm/N mm for two distal screws. The torsional compliance analog between two groups was found to be statistically insignificant(p=0.23). In conclusion, One distal interlocking screw was not inferior to two interlocking screws in terms of biomechanical characteristics, especially torsional compliance analog.

Nitrous oxide is the most commonly used inhaled anesthetic in the part of anesthesia and used up to 75% of concentrations. Diffusion hypoxia among the disadvantages or harmful damages due to nitrous oxide exposure must be prevented by moderate flow (4-6 liters/minute) of oxygen for a few minutes. This study was investigated the effect of the amount of oxygen flow on the speed of removal of exposed nitrous oxide followed by oxygen flow rate of 2, 4, and 6 liters/minute when halted the administration of nitrous oxide. These variables were taken in 57 patients of 16 to 60 years old, who were performed the elective surgery. All patients were anesthetized with the 0.5-1.5 MAC of enflurane or isoflurane combined with nitrous oxide(2 liters/minute) and oxygen(2 liters/minute), and paralyzed with IV route pancuronium 0.07-0.08 mg/kg. Ventilation was controlled with Ohmeda 7000 ventilator (BOC Health Care Inc, Madison, USA), using a constant tidal volume of 10 ml/Kg of ideal body weight. Ventilatory rate was adjusted 12 times/minute to maintain the end-tidal CO2 of 20-35 mmHg. After 60 to 90 minutes of anesthesia, the nitrous oxide/oxygen mixture was changed to 100% oxygen, but ventilation being held constant. The results were as follows; 1) After the first 30 seconds, the end-tidal nitrous oxide concentration was 39.6+/-+3.7% in 2 liters/minute of oxygen flow, 28.2+/-5% in 4 liters/minute and 23.4+/-6.3% in 6 liters/minute. 2) After the 2 minutes, the end-tidal nitrous oxide concentration was 29.1+/-3.6% in 2 liters/minute of oxygen flow, 14.4+/-3.2% in 4 liters/minute and 10.13+/-2% in 6 liters/minute. 3) After the 5 minutes and 30 seconds, the end-tidal nitrous oxide concentration was 16.4+/-3.3% in 2 liters/minute of oxygen flow, 5.5+/-1.9% in 4 liters/minute and 4.0+/-1.7% in 6 liters/minute. 4) After 15 minutes, the end tidal nitrous oxide was 7.5+/-2.1% in 2 liters/minute of oxygen flow, 2.3+/-0.7% in 4 liters/minute and 2.0+/-0.8% in 6 liters/minute. In conclusion, the larger size of oxygen flow, the more rapid elimination of nitrous oxide. The removal rate of nitrous oxide was greatest at first 30 seconds after halting the nitrous oxide administration in all cases.

Korean Journal of Dermatology 2003;41(1):123-126
Cold urticaria and cholinergic urticaria are considered to be distinct disorders in which mediator release and hives can be induced by different stimuli. Cold urticaria can be induced by cold stimuli, and cholinergic urticaria, characterized by micropapular wheals, by exercise, emotional stimuli, or other stresses that increase the body temperature. While neither cold urticaria nor cholinergic urticaira is rare, it is unusual to see both disorders occurring in the same patient. Also, our case presents atypical urtication to cold exposure, similar to classic cholinergic urticarial lesions, called "cold-induced cholinergic urticaria". We present a 20-year-old man with 4-year history who experienced generalized micropapular wheals induced by cold exposure as well as exercise and hot environment.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 2001;28(4):408-412
Plagiocephaly is a premature unilateral coronal craniosynostosis consisting of flattening of the involved frontal region and low-set orbit in affected side and compensatory occipital bulging in contralateral side with resultant facial asymmetry. The authors experienced a 20-year-old male having frontal and posterior palgiocephaly with asymmetric mid-facial appearance in left side who had undergone the strip craniectomy of the coronal suture when he was 100 days old. We performed total intracranial total calvarial remodeling including occipital region followed by two-jaw operation seven months later. Cranial vault was cut into three transverse bone flaps; anterior bi-frontal bone flap, posterior bi-fronto-parietal bone flap, and bi-parieto-occipital bone flap. Unilateral supra-orbital bar advancement with tongue-in-groove arrangement was performed. To restore contour of occipital region, the transposition cranioplasty was done after mid-sagittal osteotomy of posterior bone flap. Seven months later, Le Fort I osteotomy and BSSRO was performed to correct jaw asymmetry and cross-bite. We believe that total correction of orbito-fronto-occipital vault including jaw surgery in plagiocephaly is mandatory for more excellent aesthetic result and effectiveness.

Choledochocele is a kind of choledochal cyst and represents a prolapse or herniation of the intramural segment of the distal common bile duct into the duodenal lumen. It is rare congenital anomaly and, easlily overlooked due to non-specific clinical symptoms, signs, and non-characteristic radiologic features. The cause of choledochocele remains uncertain and it was suggested that thete are two distinct types in the pathogenesis of it, i.e., congenital and acquired. Recently, many cases of choledochocele were reported, which diagnosed by ERCP and safely treated with endoscopic unroofing and EST followed by continued observation as well as interval ERCP and/or endoscopic ultrasonography. We present here four cases of symptomaatic choledochoceles that had been managcd by end- oscopic therapy and continucd observation.

Several studies have shown that curcumin, which is derived from the rhizomes of turmeric, possesses antimicrobial, antioxidant and anti-inflammatory properties. The antitumor properties of curcumin have also now been demonstrated more recently in different cancers. This study was undertaken to investigate the modulation of cell cycle-related proteins and the mechanisms underlying apoptosis induction by curcumin in the SCC25 human tongue squamous cell carcinoma cell line. Curcumin treatment of the SCC25 cells resulted in a time- and dose-dependent reduction in cell viability and cell growth, and onset of apoptotic cell death. The curcumin-treated SCC25 cells showed several types of apoptotic manifestations, such as nuclear condensation, DNA fragmentation, reduced MMP and proteasome activity, and a decreased DNA content. In addition, the treated SCC25 cells showed a release of cytochrome c into the cytosol, translocation of AIF and DFF40/CAD into the nuclei, a significant shift in the Bax/Bcl-2 ratio, and the activation of caspase-9, caspase-7, caspase-6, caspase-3, PARP, lamin A/C, and DFF45/ICAD. Furthermore, curcumin exposure resulted in a downregulation of G1 cell cycle-related proteins and upregulation of p27KIP1. Taken together, our findings demonstrate that curcumin strongly inhibits cell proliferation by modulating the expression of G1 cell cycle-related proteins and inducing apoptosis via proteasomal, mitochondrial, and caspase cascades in SCC25 cells.
