Aneurysmal benign fibrous histiocytoma(ABFH) is a relatively rare variant and has a distinctive histopathological features, that is collections of capillaries, foci of hemorrhage, siderophages, and foamy macrophages surrounding cleft-like and cavernous blood filled spaces in the tumor. But, in spite af the distinctive features, it is not infrequently confused with malignant melanoma, angiomatoid malignant fibrous histiocytoma, and vascular tumors such as spindle cell hemangioendothelioma, nodular Kaposi's sarcoma and angiosarcoma. We report a case of ABFH developed on the left upper extremity of a 41-year-old man.

Primary varicella infection usuelly runs a benign clinical course in the helthy population. However, hemorrhagic chicken pox presents with a very extensive eruption of hemorrhagic vesicles in patients with decreaed platelets or impaired immunity and is accompanied by severe constitutional symptoms. A 7-year-old male was admi due to abdompal pain for 1 day and peneralized vesicular eruption for 5 days. The eruption first appeared on the trunk and then spread to involved face, scalp and extrsmities. The skin rash was compatable with varicella but despite the administration of acclovir intravenously, the vesicular eruption became hemorrhagic. Ten days after admission, having experienced cardisc arrest twice and with his mental state in coms, he was diseharged as his situation was hopelesa. We have experienced a giatient diagnosed as having hemorrhagie, chicken pox complicated by encephalopathy.

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: Hydration, the water content of the stratum corneum, is an important factor in both the appearance and the barrier function of the skin. Many non-invasive methods have been developed in order to assesa the hydration state of the skin and the effect of various moisturizers. The hydrometer and carneometer are commercially available instruments which are widely used in dermatologic research. OBJECTIVE: Our purpose was to compare the measuring usefulnes of both instruments on normal subjects with a wide range of hydration states of the hornylayer. METHODS: We measured the conductance with the hydrometer and the capacitance with the corneometer in various hydrating eonditions and compared both insruments. RESULTS: Conductance had a non linear correlation with capacita ice. Capacitance measured with the corneometer had a high sensitivity to moisture in a wide range of hydration levels. On the other hand, conductance guaged with the hydrometer showed a few sensitivity to moisture at a low level. When the hydretion level was measured after a moiturizer was added, 10 % urea cream showed a sharp increase by 256% in terms of conductanae, and H-base by 97.8%. Mineral oil decreased by 41.5% and petrolatum by 62% respectively. On the other hand, when measured in terms of capacitance under the same conditions as above, 38.9 increase in 10% urea cream, 19.3% increase in H-base, 20% decrease in mineral oil, and 43.5 % decrease in petrolatum were reported. Conductance showed a higher hygroscopicity and a lower water holding capacity than capacitance did. When the measurement of the moisture level iri virious parts of the human body is performed, the corneometer provided us with more stable alies than the hydrometer. While the hydrometer can not the available and appropriate under the condition of insulation, the corneometer can measure moisture levels even down at the depth of 250mm. When measured after the oily surface of the forehead was cleansed with soft tissue, conductance and capacitance revealed higher values of moisture levels than before the eleanin. However, there is no statistical significance in these values. CONCLUSION: The hydrometer is a more appropriate tool for the measurement of moisture at a high level, and the corneometer at a low moisture level. The hydrcmeter is a more sensitive method of measuring the increase and the decrease in the moisture level.

Nevus flammeus is a benign but cosmetically devascating congenital inalformation involving mature capillaries. The copper vapor laser is a therapeutic device which had been newly applied to this. Yellow copper vapor light is absorbed by the intraluminal oxyhemoglobulin mo ecules, leading to the destruction of blood vessels. This study was undertaken to evaluate the histobigic findings in a patient with nevus flammeus according to the sequential time after copper vapor laser therapy. The results were as followed, One hour after treatment, nonspecific damages to the epidermis and upper part of the dermis were observed. The specific damage to the vessels which showed thrombi formations and partial disruption of the vessel walls was prominent. One cay after treatment, degeneration of the epidermis and sepaiation of the dermoepidermal junction were apparent. Three days after treatment, extravasations of a small amount of erythrocytes and inflanimatory cell infiltrations were present, especially around the vessels. Seven days after treatment, the capillaries showed a deposition of fiorinoid material around themselves. Partial disappearance of the vessel walls was seen. There was hisi ologic evidence of the replacement of abnormal ectatic vessels by normal appearing vessels with small uminal diameters, surrounded by endothelial cells.

BACKGROUND: Insulin resistance syndrome shows extreme insulin resistance and is associated with acanthosis nigricans. We can differentiate it into type A insulin resistance that has insulin receptor defect, and type B insulin resistance due to insulin receptor autoantibody. Type B insulin resistance was firstly described by Kahn in 1976. It was often found in adult female and showed autoimmune characteristics. As clinical characteristics, there are hyperglycemia, hypoglycemia, hyperinsulinemia, extreme insulin resistance and acanthosis nigricans. METHODS: We investigated 17 insulin receptor autoantibody positive cases and 8 cases of normal control who had visited Wonju Christian Hospital from October 1994 to December 1995. Among insulin receptor autoantibody positive subject, male was 4 cases and female 13 cases. Their mean age was 42.2. We compared patients who had insulin receptor antibody positive acanthosis nigricans(IRA) with normal controls. IRA patients were 6 cases(35.3%) of nomal glucose tolerance, 11 cases(64.7%) of abnormal glucose tolerance including overt diabetes mellitus. RESULTS: The 11 cases(64.7%) among IRA patrents were obese and 13 cases(76.5%) had hyperininsulinemia. In IRA patients, mean serum insulin concentration during oral glucose tolerance test was 202.1mU/mL and it was greater than 46.3 of normal controls. Insulin sensitivity in 1.79mg/L * mM * xmU * min normal controls was higher than 0.74mg/L * mM * min of IRA patients. CONCLUSION: IRA patients showed abnormal glucose tolerance including overt diabetes millitus, severe insulin resistance, hyperinsulinemia and obesity.
