Silicone gel sheeting is widely used to manage the hypertrophic or keloid scars. Since first reported in 1982 to be an effective treatment for burn scars and contractures, many authors reported its efficacy to treat scars. Chemically silicone gel sheet composed of cross-linked dimethy1 and vinyl enblocked polydimethylsiloxane polymer. The exact mechanism of silicone gel sheet to treat hypertrophic scar was still unknown, but decreasing the water vapor transmission was supposed to level the scar. During out clinical experience, a few patients suffered from skin problems by silicone gel sheeting. So we designed a study to determine the severity of skin hypersensitivity of silicone gel sheeting. Four types of silicone gel sheets were applied to upper arms of 140 healthy voluntees. Resultant skin lesions were analysed 48 and 96 hours later to differentiate the irritation and the true hypersensitivity. About 30 percent of voluteers represented mild skin irritability(48 hours later), but true skin hypersensitivity was not found(96 hours later). The site to be applied with silicone gel sheet is very critical area, so pretesting the irritability of silicone gel sheeting to individuals is an important step to control the hypertrophic scar.

Paget's disease is classified, according to location, as mammary or extramammary disease. Extramammary Paget's disease especially in the vulva is extremely rare. Several hundred cases have been described worldwide. Patients with Paget's disease of the vulva are usually white and postmenopausal. The cause of which remains elusive. A case of vulva Paget's disease is presented with brief review of literature.

BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.
