Treatment by External Fixation with External Compression Device was used for the displaced fractures of the proximal humerus. Especially in the old aged patient and patient with severe associated injury, this method was excellent for the early, painless motion of the shoulder and then good functional result. This experimental treatment was performed in 8 patients, and its merits were as follows: 1. The technique of operation was relatively easy, and was possible within a short time with minor injury. 2. The quality of reduction was good in all cases. 3. By the compression effect on the fracture site and firm maintenance of reduction during the treatment, solid healing as in internal fixation was possible. 4. Firm maintenance of reduction & minimal injury of soft tissue made possible early painless and wide ROM exercise, and then good functional result.

A fixed drug eruption is a cutaneous reaction caused by various drugs, which include phenazone derivatives, barbiturates, sulfonamides, tetracyclines and phenolphthaleins. An eruption caused by piroxicam is very rare and there have been no previous reports in Korea. A 49-year-old woman was seen with mutiple erythematous patches and some bullae that appeared after oral administration of piroxicam. The patient had had two similar episodes after oral administration of piroxicam. We performed patch test with piroxicam and could confirm a fixed drug eruption caused by this durg.

3.Radiologic Findings of Nail-Patella Syndrome: Case Report.
Journal of the Korean Radiological Society 2004;51(3):341-343
Nail-patella syndrome is a rare autosomal dominant pleiotropic disorder characterized by dysplasia of the nails, patellar aplasia or hypoplasia, iliac horns, and dysplasia or dislocation of the elbow. We experienced a case of nail-patella syndrome. NPS is a relatively uncommon disease; however, an understanding of the typical radiologic findings is useful in establishing the diagnosis and guiding the treatment.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.

OBJECTIVE: Our purpose was to describe the clinical progress and the maternal and fetal outcome in 16 pregnancies complicated by the HELLP(hemolysis, elevated liver enzymes, low platelet). Material: We reviewed the maternal and neonatal charts from 16 consecutive pregnancies complicated by the HELLP syndrome among 302 pregnancies complicated by preeclamsia and eclamsia managed at our hospital during the period of 4 years from June 1994 through June 1998. The HELLP syndrome was defined by previously published laboratory criteria. We assessed the time of onset, presenting symptom, laboratory finding, mode of delivery, fetal and maternal complication in each case. We also reviewed the clinical finding in detail in the case resulted in maternal death. RESULTS: In regards to the time of onset, 15 cases (93.7%) occurred at antepartum period and only 1 case (6.2%) occurred at postpartum period. Among the 15 cases occurred at antepartum period, 13 cases (81.25%) developed at 27 to 36 weeks gestation and 2 cases (12.5%) developed at near term. In regards to the presenting symptom, twelve patients (75%) complained of right upper quardrant or epigastric pain. Of 16 patients, 12 patients (75%) experienced headache and 10 patients (62.5%) complained of nausea, or vomiting and 5 patients (31.2%) had visual disturbance. The laboratory finding of all 16 cases were as follow; the mean level of platelet: 68700/mm3 (range: 48000 to 91700), the mean level of serum asparate aminotransferase: 335 IU/L (range: 62 to 135), the mean level of lactic dehydrogenase: 910 IU/L (range: 558 to 5794), and the mean level of total bilirubin: 2.6 mg/dl (range: 0.7 to 10.4). To review the mode of delivery, cesarean sections were done on 10 patients (62.5%) including 7(43.7%) emergency and 3(18.7%) elective operations. However, 6 patients (37.5%) delivered vaginally. Maternal complications were as follow; abruptio placenta in 1 case (6.2%), DIC in 2 cases (12.5%), pulmonary edema in 3 cases (18.7%), pleural effusion in 4 cases (25%), renal failure in 4 cases (25%), and 1 case of death. Fetal and neonatal outcome was assessed; 9 cases of intrauterine growth retardation (56.2%), meconium stained in 3 cases (18.7%), 2 stillbirth (12.5%), and 2 neonatal death (12.5%). CONCLUSION: HELLP syndrome is associated with serious maternal and fetal morbidity and mortality.

Antiepileptic drug hypersensitivity syndrome (AHS), a delayed immunological reaction, is a relatively rare side effect of antiepileptic drugs and is usually overlooked. An array of symptoms can occur one to eight weeks after treatment with an antiepileptic drug. Symptoms may be as simple as a fever, skin rash, or lymphadenopathy, but may eventually involve internal organs and cause fatal outcomes. Additionally, because the symptoms resemble the features of various arrays of diseases and the reported mortality rate is approximately 10%, the importance of early diagnosis and ability to differentiate AHS from other diseases cannot be overemphasized. We report a case of a 14-year-old girl with AHS caused by lamotrigine, which mimicked atypical Kawasaki disease and infectious mononucleosis.

OBJECTIVES: The primary objective of this study is to compare model performance of machine learning methods with that of a previous study in which a nonlinear mixed effects model was created using NONMEM(R) for the pharmacokinetic and pharmacodynamic data for propofol. The secondary objective was to evaluate if a pharmacodynamic model describing the relationship between the dose of propofol and bispectral index (BIS) outperform that describing the relationship between a pharmacokinetic model derived-predicted concentrations of propofol and BIS. METHODS: Data were collected during a study involving the infusion of propofol into healthy volunteers. Pharmacokinetic and pharmacodynamic models were constructed using artificial neural networks (ANNs), support vector machines (SVMs), and multi-method ensembles and were compared with the nonlinear mixed effects method as implemented by NONMEM(R). Model performance was assessed by goodness-of-fit statistics, paired t-tests between predicted and observed values for each model and scatterplots. RESULTS: In pharmacokinetic analysis, ensemble I, the mean of ANN and NONMEM(R) predictions, achieved minimal error and the highest correlation coefficient. SVM produced the highest error and the lowest correlation coefficient. In pharmacodynamic analysis, ANN exhibited the best performance. An ANNModel describing the relationship between the dose of propofol and BIS was not inferior to an ANN model describing the relationship between predicted concentrations of propofol derived from an ANN pharmacokinetic model and BIS. CONCLUSIONS: In pharmacokinetic analysis, ensemble combined with ANN achieved slightly better performance than NONMEM(R). The relationship between the dose of propofol and BIS can be predicted without considering pharmacokinetics of propofol.
