BACKGROUND: The pediatric CPR is rather uncommon practice than adult CPR in emergency room. Therefore, few interest and studies were focused in pediatric CPR. The object of this study is to make an analysis about pediatric CPR performed within hospital setting. METHOD: From January 1. 1990 to December 31. 1996, a total of 59 patients, less than 15-year-old, who received cardiopulmonary resuscitation were subject of this study. The study was done retrospective chart analysis for sex, age, weight, the place of cardiac arrest, initial EKG rhythms, endotracheal tube size, the causes of arrest, CPR time, ROSC, the amount and types of CPR drugs used during resuscitation. Wilcoxon rank sum test and chi2 test were used to compare the dose of drugs during CPR in each group. RESULTS: There were no statistical difference between ROSC and non-ROSC group in place of arrest, initial EKG rhythms, CPR time, dosage of CPR drugs. CONCLUSION: The uniform reporting guideline of pediatric advanced life support should be used for future pediatric CPR study, such as Utstein style guideline in pediatric CPR.

BACKGROUND: Activated charcoal has been widely used as an adsorbent for the management of drug intoxicated patients in the emergency department(ED). Although there are several commercial ready-mixed charcoal suspension preparations in the market, we are using custom-made suspension from hospital grade bulk charcoal powder. We designed this study to compare the adsorptive capacity of the Actidose Aqua(R), which is a commercial charcoal product, Fuller's earth, and custom-made activated charcoal used in our ED. METHODS: First, we performed modified USP methylene blue adsorption test which is a standard adsorption test for activated charcoal. Then, the drug adsorption test for phenobarbital, acetaminophen, salicylate, and aminophylline was done. Graded amount of three adsorptives were added to the stock solutions of each drugs. The adsorption test were performed as follows: The vials containing drugs and adsorptives were shaken for 30 minutes to ensure adsorption equilibrium, then the suspension was filtered through in-line filter. The filtrates were analyzed by ultraviolet spectroscopy to determine the residual drug concentrations. Finally we examined and compared the surface area and the structure of activated charcoal and Fuller's earth using scanning electron microscopy. RESULTS: In methylene blue adsorption test, the adsorption rate was 60.1% in Actidose Aqua(R) and 59.0% in custom-made charcoal, and 70.2% in Fuller's earth. For the phenobarbital, acetaminophen, and sallcylate, the adsorption rate of Actidose Aqua(R) and custom-made charcoal was greater than 90% with the ratio o adsorptives to drugs over 10:1. For aminophylline, two charcoal products showed excellent adsorption in 5:1 ratio. But Fuller's earth showed poor adsorption in all rages. CONCLUSION: Custom-made activated charcoal showed a comparable adsorption capacity to Actidose Aqua(R). Fuller's earth showed a poor performance to be used as a substitute for activated charcoal in acute drug poisoning otherwise paraquat.

The prognosis of symptomatic bilateral internal carotid artery occlusion is extremely poor. To our knowledge, there are few reports regarding the proper management of this catastrophic event. We present two cases of progressive stroke with acute internal carotid artery occlusion and contralateral chronic carotid occlusion, who were treated by urgent recanalization using stents. In two cases, complete recanalization was achieved and the clinical outcomes were favorable. We suggest that early endovascular treatment using stents may salvage the occluded vessel and may also offer a more successful clinical outcome. Further study will be necessary in order to define the proper management of this catastrophic event.

OBJECTIVE: This study assesses the hypothesis that preeclampsia is associated with the change of oxidative system balance by measuring the lipid peroxidation and antioxidant activity in preeclampsia. METHOD: Venous blood samples were collected from twenty women with preeclampsia and twenty women with uncomplicated pregnancies. Total lipid peroxidation, total antioxidant activity, antioxidant enzyme activity and antioxidant concentration were measured using flow injection-chemiluminescent method. RESULTS: 1. Total lipid peroxidation(PCOOH) was higher in preeclampsia(717.22+/-93.08 pmol/ml) than in normal pregnant(486.86+/-43.15 pmol/ml) (P<0.05). 2. Total antioxidant activity was significantly higher in preeclampsia(46.02+/-5.95 % inhibition) than in normal pregnant(38.59+/-7.57 % inhibition) (P<0.05).3. Antioxidant enzyme, catalase activity in RBC was lower in preeclampsia(346.59+/-82.84 unit/gHb) than in normal pregnant(440.62+/-72.8 unit/gHb) (P<0.05).4. Antioxidant, alpha-tocopherol concentration in RBC was slightly lower in preeclampsia(33.21+/-7.82 ng/gHb) than in normal pregnant(36.06+/-6.86 ng/gH), but there was no statistically significant difference (P<0.05). CONCLUSION: This data seems to show that preeclampsia is associated with an imbalance between the lipid peroxidation and the antioxidant system.

Epidermal cysts slowly growing, intradermal or subcutaneous tumors that usually cease growing after having reached 1 to 5 cm in diameter. We report a case of giant epidermal cyst on the scapular region with the appearance of well delineated huge mass measured 19×17×14cm in size. Its clinical and surgical management are illustrated.
Epidermal Cyst

Epidermoid cyst originating within the diploic space of the bony orbit is rare. The authors describe two cases of epidermoid cyst of the orbit. The clinical presentation was dependent on the location of the slowly expanding epidermoid cyst. Proptosis caused by intraorbital extension of the mass was the presenting sign in both case. The finding in orbit CT scan appeared to be specific for intradipolic epidermoid cyst. Their clinical presentations and surgical management were briefly discussed.

In gliomas, the most frequently studied tumor suppressor gene is the p53 gene which has been found to be mutated in a considerable fraction of astrocytomas and glioblastomas. Mutations that alter the function of the p53 gene product are thought to play a critical role in glial tumorigenesis. The murine double minute 2(MDM2) gene has been shown to code for a cellular protein that forms a complex with the p53 tumor suppressor gene product and inhibits its function. The fact that MDM2 can negatively regulate p53 suggests MDM2 could function as an oncogene when overexpressed. We investigated the expression of p53, MDM2 and proliferative activity of the tumor cells in 71 cases of gliomas(17 cases of differentiated astrocytomas. 25 cases of anaplastic astrocytomas and 29 cases of glioblastomas). Their paraffin-embedded tissue sections were immunostained with monoclonal antibody(p53 and PCNA, proliferating cell nuclear antigen) and polyclonal antibody(MDM2) for detection of p53, MDM2 and PCNA respectively. The results were as follows: The p53 staining was positive in 28 cases(39.4%) and MDM2 staining in 5 cases(7.0%) of 71 gliomas. The p53 positive-staining was detected in 2 cases(11.8%) of 17 differentiated astrocytomas, 9 cases(36.0%) of 25 anaplastic astrocytomas and 17 cases(58.6%) of 29 glioblastomas. The p53 expression was associated with malignancy grade(p<0.005) and proliferative activity was strongly associated with malignancy grade(p=0.0001). The p53 expression was closely associated with proliferative activity : p53-positive tumors had significantly higher median PCNA-labeling index than p53-negative tumors(40.6+/-10.1% versus 19.6+/-15.0%)(p=0.0001). But, MDM2 expression was not associated with proliferative activity(p=0.4575). The proportion of p53 immunoreactivity had significant association with proliferaive activity: the more the proportion of p53 immunoreactivity increased, the higher PCNA-labeling index elevated(p=0.0001). None of the tumors with MDM2 expression showed immunoreactivity for p53. These results suggest that the mutation of p53 gene plays a critical role in malignant transformation in glioma and it could be the prognostic factor for histologically same grade gliomas and that a subset of human gliomas escapes from p53-regulated growth control by amplification and overexpression of MDM2. Therefore gene study targeting these genes may be useful for the management of human glioma as a diagnostic modality.
