The sunscreening effect can be varied according to the vehicles. Therefore the purpose of this study is to compare the effect of vehicles(bases) on sun protection in p-aminobenzoic acid, cinnamate and benzophenone sunscreens with same concentration (2.5%), We included ointment (white petrolatum), cream (hydrophilic), milky lotion and alcohol as the sunscreen vehicles. The test results can be summarized as follows: We could not recognize a sunscreening effect of sunscreen vehicles which did not contain sunscreening agent. In the case of p-aminobenzoic acid, the mean sun protection factor was higher in the sequence of cream, milky lotion, alcohol, ointment, each showing 9, 95+/-3.67, 8.09+/-2.56, 5.14+/-1.45, 4.35+/-1.46 respectively. In the case of cinnamate, the mean sun protection factor was higher in the sequence of cream, ointment, milky lotion, alcohol, each showing 6 46+/-1.89, 5.42+/-1.49, 4.82+/-1.84, 4.05+/-1.45 respectively. 4. In the case of benzophenone, the mean sun protection factor was higher in the sequence of cream, alcohol, ointment, milky lotion, each showing 5 .26+/-1.56, 4.94+/-1.24, 4.56+/-1.71, 4.18+/-1.23 respectively.

We report a case of atrophie blanche which was accompanied by cryoglobulinemia. The patient, 17-year-old female, have had recurrent painful ulcerations and ivory-white atrophic scars with telangiectases surrounded by hyperpigmentation. On histological examination, vessel wall thickening and hyalinization of the intima, partial vascular occlusion, vascular proliferation and mild perivascular chronic inflammatory cells infiltration and hemorrhage in the upper dermis were noted. The patient had been treated with dipyridarnol(Persantin) and acetylsalicylic acid hut the lesions had been waxed and waned.

Although a higher incidence of ectopic pregnancy has been reported after in vitro fertilization(IVF) and embryo transfer(ET), five ectopic pregnancies in one patient is very rare. We experienced a case of combined interstitial and intrauterine pregnancy as fifth ectopic pregnancies after in vitro fertilization and embryo transfer in one patient with history of bilateral salpingectomy due to previous four tubal pregnancies. Repeated transvaginal ultrasound examinations confirmed heterotopic pregnancy. In IVF-ET, bilateral salpingectomy does not remove the risk of interstitial or cornual pregnancy.

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

We report a case of multiple eccrine hidrocystoma (MEH) in a 57-year-old woman who had asymptomatic, discrete, skin-colored, shiny, firm papulovesicles on the face. These lesions enlarged during summer or when the patient did housework, and decreased in sue during winter or rest. Histologic examination showed a dilated, unilocular, cystic, invaginated structure within the middle dermis. The wall of the cyst generally consisted of two layers of Rat or cuboida1 epithelial cells. Decapitation secretion and myoepithelial cells were not observed. The lesions improved markedly with 1% topical atropine sulfate.

We report a rare case of glomangiomyoma in a 25-year-old man who had an asymptomatic, 1.5 × 1.5cm sized, round, skin-colored, soft mass on the right cheek. Histopathologically, the lesion was consistent with glomangiomyoma which showed irregularly dilated vessels lined by endothelial cells and several outer layers of glomus cells, and smooth muscles distributed within the tumor. The tumor cells were characterized immunohistochemically by the presence of smooth muscle actin, muscle specific actin, and vimentin. To our knowledge, this is the first case report of glomangiomyoma on the facial location in the Korean literature.

Author have experienced 3 cases of intractable total traumatic hyphema on conservative medical treatment and have good results after surgical management by using Model 800(A) Ocutome vitrectomy instrument. For evacuation of blood clot in anterior chamber. The conclusion were as follow; 1. We experienced no significant intraoperative complication. 2. All 3 cases achieved intraocular presure controls in early post operative state and these controls were sustained till now without any antiglaucomatous agent. 3. Good final visual acuity was obtained in pure total hyphema in which there was no other associated intraocular injury at the time of trauma.

OBJECTIVE: To evaluate the perinatal prognosis of fetuses with a single umbilical artery. METHODS: From 1992 to 1998, nineteen cases with single umbilical artery(SUA) was observed in 8,704 deliveries at Chonnam University Hospital. RESULTS: Out of nineteen fetuses, thirteen fetuses with single umbilical artery were detected by antenatal ultrasonographic examination and six fetuses were detected after birth. The male to female ratio was 0.9: 1. Congenital malformations were observed in 8 babies(42.1%) and included leg deformity, esophageal atresia, imperforated anus, ventriculomegaly, meningocele, hydronephrosis, ventricular septal defect, joint contracture, cleft lip and palate, toe anomaly, imperforated anus, kyphosis, no urethra and testis, clubfoot, patent ductus arteriosus and rnild mitral regurgitation. Among 10 cases of karyotyping analysis three cases were diagnosed as trisomy 18. Fourteen fetuses(77.8%) showed growth restriction at delivery. Antenatal obstetric complications were hydramnios(n = 3), oligohydramnios(n =2), and severe preeclampsia(n = 3). CONCLUSION: Careful ultrasonographic evaluation for the identification of a SUA is necessary because of its frequent association with congenital anomaly, growth restriction and cytogenetic abnormality.

Infantile hemangiopericytoma deserves separate consideration from adult form of hemangiopericytoma in that it has a benign clinical behavior and distinct histology. We herein report a case of infantile hemangiopericytoma in a 80-day-old male. He had multiple tender subcutaneous nodules on buttock and lower extremities which disappeared spontaneously in 10 months. Microscopically, well circumscribed multiple tumor nodules were seen in the dermis and subcutis and the nodules were consisted of haphazardly packed cells around endothelium-lined vascular slits. Infantile hemangiopericytoma is usually soliitary and spontaneously healed case has not been reported yet.
