Down syndrome is the most, well known autosomal trisomy and e large number of abnormal skin features have been reported to occur in patients with Down syndromir. including syringoma. Syringomas occur with increased frequency in patients with Down syringoma, usually limited to the region around the eyes. but few cases of eruptive syringoma with Down syndrome have been reported. We reported the case of familial eruptive syringoma in a 13 years old patient with Down syndrome.

The surgical reconstruction of complex facial injuries have focused on the following; early one-stage repair, exposure of all fracture fragments, precise anatomic rigid fixation, immediate bone grafting, and definite soft tissue management were the main surgical procedures, as in other facial bone injuries. Complex facial bone fractures involving dentition should be managed by the same principles. However, conventional methods can not achieve accurate preinjury occlusion when there are unstable fracture segments, edentulous state, or complex palatal/maxillary and mandibular fractures. Seventeen patients were surgically reconstructed in conjunction with dental impression, model surgery, and fabrication of dental splints to establish better occlusion. Among the facial fractures that had the occlusal problem, maxillary/palatal fractures and complex mandibular fractures, were the major indications for fabrication of acrylic splints. During operation, fracture segments were reduced and repositioned according to dental wear facets of the prefabricated occlusal splint and then temporary intermaxillary fixations were performed. This allowed us to accomplish precise anatomical reduction and rigid intrenal fixations. The postoperative occlusions were acceptible and no complication occurred as direct effects of dental splint. We suggest that fabrication of an acrylic occlusal splint is necessary for the management of complex facial injuries involving dentition.

Ependymomas constitute no more than 5 to 7% of all primary CNS neoplasm and their biologic behavior is difficult to predict by microscopic appearances. Recently, many studies have attempted to correlate biologic behavior with tumor proliferation index, tumor suppressor gene and oncogene using immunohistochemical stains. We evaluated 25 cases of surgically resected intracranial ependymomas for the proliferation activity using Ki-67, and expression of p53 and bcl-2 protein with regard to the prognosis. The cases were divided into 17 ependymomas (WHO Grade II), 3 papillary ependymomas (WHO Grade II), and 5 anaplastic ependymomas. Clinically, the patients were divided into two groups, recurrent (18 cases) or non-recurrent (7 cases). The Ki-67 proliferation index was significantly higher in the recurrent group (p<0.05) and in the younger ages (correlation index=0.534). Although Ki-67 proliferation index was higher in anaplastic ependymoma, it was not significant statistically (p>0.05). p53 protein expression tended to increase in the patients who had anaplastic ependymoma and in the recurrent group. bcl-2 expression was not correlated with histologic grade or recurrence of the tumor. We conclude that Ki-67 proliferation index and p53 expression are important markers for predicting biologic behavior of ependymoma.

Livedo vasculitis clinically shows purpuric papules and recurrent ulcers in the lower extremities, mainly on the ankles, leaving characteristic scars called atrophie blanche after the healing of the ulcers. Its characteristic histopathologic features and clinical evolution indicate that the common pathologic event is occlusion of vessels in the middle and deep dermis. In Korean literature, seven cases of this disease have been reported but the response of the treatment was not, satisfactory. We report three cases of livedo vasculitis cleared by combined ther by of acetylsalicylic acid, dipyridamole and nifedipine, which has not been reported in Korean literatur.

Hydroa Vacciniforme is a rare, chronic, photosensitivity disorder witli onset in childhood that is characterized by recurrent, discrete vesiculation, necrosis and vacciniform scarring limited to sun exposed skin. We report a case of hydroa vacciniforme associated with ocular inwlvment in which vesicles could be induced only with single MED exposure to UVA.

Experimental, epidemiological and clinical studies indicate and important relationship between abnormalities in serum lipoproteins and atherosclerosis. With the introduction in 1965 by Fredrickson and Lees of a system for phenotyping hyperlipoproteinemias, quantitation of pre-and beta-lipoproteins gained much significance, and hence, the development of simple method for studying serum lipids and lipoproteins is needed. In the past, several methods have been proposed for the estimation of serum lipoproteins by electrophoresis. Authors observed serum total lipoprotein, beta-lipoprotein, pre-beta-lipoprotein and alpha-lipoprotein fractions in 80 (male:40, female;40)normal individuals with electrophoesis using cellulose acetate membrane instead of filter paper and concluded as follow: 1) Total lipoprotein and beta-lipoprotein levels had increasing tendency according to aging on both sexes. 2) Serum pre-beta-lipoprotein level also had increasing tendency according to age on both sexes and these features are more conspicious after fifth decade. 3) Electrophoresis using cellulose acetate membrance seem to be convinient method for analysis of serum lipoproteins especially pre-beta-lipoprotein fraction. 4) This method can be likely applied as routine screening test of hyperlipemia.

Although the conclusion is controversial, there has long been an appealing notion that catecholamines may be involved in some way in the pathogenesis of primary hypertension and almost invariably most of hypotensive drugs involve at various sites of the neuron and produce their effect by depletion of norepinephrine in the sympathetic nerve ending. The authors undertook the comparative study on catecholamine depleting action of 3 most effective drugs available for the treatment of hypertension, reserpine, guanethidine and alpha-methyldopa, measuring the plasma catecholamine levels and urinary exceretion of caecholamine by the modified fluorometric method of Weil-Malherbe and Bone during the treatment of hypertension. The results are as follows: 1) Before the administration of hypotensive drugs, mean blood pressure was 180/110mmH, mean psalma epinephrine level was 0.36+/-0.23gamma%, mean plasma norepinephrine level was 0.48+/-0.35gamma%, 24 hours urinary excretion of epinephrine was 3.6+/-0.12gamma/day and 24 hours urinary excretion of norepinephrine was 68.9+/-0.34gamma/day. 2) In group 1 (reserpin administered group), the mean blood pressure was 190/110mmHg before the treatment and which was declined to 155/89mmHg on the last day of 4th week, in group 2 (guanethidine administered group), the mean blood pressure measured before the treatment was 185/110mmHg and which was declined to 150/85mmHg on the last day of 4th week, and in group 3 (alpha-methylodpa administered group), the mean blood measured pressure measured before the treatment was 182/110mmHg and which was declined to 153/88mmHg on the last day of 4th week. 3) After the treatment for 4 weeks with reserpin guanethidine and alpha-methyldopa, the mean plasma epinephrine levels were declined from 0.37+/-0.12gamma% to 0.11+/-0.08gamma% in group 1, from 0.38+/-0.16gamma% to 0.14+/-0.10gamma% in group 2 and from 0.33+/-0.23gamma% to 0.10+/-0.09gamma% in group 3. 4) The mean plasma norepinephrine levels were declined from 0.05+/-0.21gamma% to 0.22+/-0.12gamma% in group 1, from 0.51+/-0.25gamma% to 0.20+/-0.10gamma% in group 2 and from 0.51+/-0.21gamma% to 0.20+/-0.11gamma% in group 3 after the treatment of 4 weeks respectively. 5) Urinary exceretion of epinephine was declined from 32.3+/-0.16gamma/day to 10.4+/-0.10gamma/day in group 1, from 34.5+/-0.34gamma/day to 17.2+/-0.16gamma/day in group 2, and from 28.2+/-0.14gamma/day to 10.3+/-0.11gamma/day in group in group 3 after the treatment of 4weeks duration. 6) The mean value of 24 hours urinary excretion of norepinephrine was declined to from 72.2+/-0.35gamma/day to 28.5+/-0.14gamma/day in group1, from 69.2+/-0.34gamma/day to 22.6+/-0.21gamma/day in group 2 and from 68.6+/-0.34gamma/day to 18.2+/-0.10gamma/day in group 3 after the treatment of 4 weeks duration. 7) From the above result we can summarized as follows: Antihypertensive effect of each drugs was; guanethidine>alpha-methylodopa>reserpin in order but depressing action plasma norepinephrine levels was; alpha-methyldopa>guanethidine>reserpin and depressing effect of urinary norepinephrine excretion was; alpha-methyldopa>guanethidine>reserpin, in order.
