Previous observations have demonstrated that fibronectia (FN) is deposited high abundance in basal cell carcinoma (BCC) stroma. Since FN is a glycoprotein which promotes interaction between cells and extracellular matrix, it may been important component of slowly expansile carcinoma such as BCC. Furthermore, BCCs aggressiveness varies with it's histologic appearance. The authors investigated distribution of plasma FN (pFN) in 8 BCC cases with various histologic types (3 nodulocystic type, 2 infiltrative type, 2 keracotic type, 1 adenoid type) and 4 squamous cell carcinomas (SCC), which have a more aggrcisive biologic behavior than BCC using immunohistochemical staining. In normal skin, pFN was strongly positive at the clenzoepidermal junction and perivascular area with a linear pattern, and in the papillary dermis with a reticular pattern, and was weakly positive in the reticular dermis. In BCC, pFN was strongly positive in nodulocystic BCC, with the highest concentration along the periphery of the tumor island in a filamentous pattern, .hereas, it was moderately positive in adenoid, keratotic, infiltrative BCC stroma. In SCC, pFN was weakly positive around tumor the margins with a thin, coarse deposition These results show that with epidermal tumors, the degree of the pFN expression in stroma is propotional to their aggressiveness.

PURPOSE:Hypochondroplasia is a skeletal dysplasia characterized by poor childhood growth and an inadequate pubertal growth spurt. Final height attainment of hypochondroplasia has been reported to range between 120 and 152cm. Increased availability of growth hormone with the introduction of recombinant human growth hormone has allowed for clinical trials in a number of growth hormone sufficient children with growth problems. The purpose of this study was to assess the growth promoting effect of human growth hormone in children with hypochondroplasia. METHODS:Five patients with hypochondroplasia diagnosed by clinical and radiological findings between 1993 and 1997 at our hospital was aged 3 and 1/2 -11 and 1/2 years. Each patients continuously received human growth hormone 0.6-0.7U/Kg/week, intramuscularly or subcutaneously in 6-7 divided dose for 2 years. Standard auxologic assessment was carried out every 3 month interval in the first year after commencement of therapy and then same assessment was 6 monthly. Bone age was assessed 6 monthly using Gleurich-Pyle method. RESULTS:Mean height velocity of pretreatment and year 1 and 2 of GH treatment were 3.9+/-0.7, 6.5+/-1.8 and 5.7+/-1.5cm/year, respectively. Mean height standard deviation score for chronological age of pretreatment and year 1 and 2 of GH treatment were -2.7+/-0.3, -2.4+/-0.3 and -2.2+/-0.4, respectively. The increase in the height velocity diminishes over the subsequent year. The increment of bone age after GH treatment were same as the increments of chronological age. CONCLUSION: Short-term GH therapy increases the height velocity of children with hypochondroplasia, but the effect of GH therapy on final height remains unknown.

Glucose-6-phosphate dehydrogenase(G6PD) deficiency is the most common X- linked inherited disorder and is estimated to affect 400 million people worldwide. But the incidence of this disease is very rare in far-east Asia, especially in Korea. Many drugs and infections cause hemolytic anemia in patients with G6PD deficiency. We experienced a case of G6PD deficiency with chronic hepatitis B. The diagnosis was made by clinical symptoms, laboratory data including serologic test and bone marrow findings. We report a case of G6PD with chronic hepatitis with a brief review of related literatures.

PURPOSE: Thyroid disease is the most common endocrine disease in childhood. Thyroid hormone has critical effects on growth and development, especially in childhood. We survey the prevalence, sex and age distribution, symptoms and thyroid function states of thyroid diseases in childhood. METHODS: Three hundred ninety one children who were diagnosed as having thyroid disease at department of pediatrics, St. Mary's hospital from Jan. 1987 to Dec. 1998 enrolled in this study. RESULTS: 1) The ratio between male and female patients was 1: 5.3. Age distribution was puberty, school age and infancy in their order of frequency. 2) The results of thyroid function tests showed normal function in 210 cases (53.7%), increased function in 95 cases(24.3%), and decreased function in 86 cases (22%). 3) Simple goiter, Graves disease, and chronic lymphocytic thyroiditis were the most common diseases in euthyroid, hyperthyroid, and acquired hypothyroid state, respectively. 4) The most common sign and symptom was goiter in euthyroid(100%), hyperthyroid(98.8%) and acquired hypothyroid state(96.2%). Forty of 68 cases(58.8%) with congenital hypothyroidism were detected by neonatal screening. CONCLUSION: Simple goiter, chronic lymphocytic thyroiditis and Graves disease were common acquired thyroid diseases in childhood, and goiter is the most common clinical manifestation in acquired thyroid disease. Recently, increasing number of congenital hypothyroidism was detected by neonatal screening test.

Adrenal cortical carcinoma is a rare disease both in adults and in children. Most of these tumors are functional, especially in children, producing endocrine syndromes such as virilization, Cushing syndrome, hyperaldosteronism or feminization. We experienced a case of adrenal cortical carcinoma in a 7yr old boy who showed features of virilization such as rapid growth rate, penile enlargement, and pubic hair. This case was diagnosed with typical hormonal findings and abdominal MRI and confirmed by pathologic findings. He was successfully treated by total left adrenalectomy and has been followed up without problem over eight months.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

To elucidate the funcion of arachidonic acid as a secondary brain edema facotr, the infusion edema model was constucted using adult cats with studies of somatosensory evoked potentials, regional cerebral blood flow of white matters, brain water contents, magentic resonance images and histological findings. Among 50 cats, 6 cats were used as sham poerated group without infustion and in 45 cats solutions of various concentrations of arachidonic acid and physiologic saline were infused into the left and right frontal white maters respectively. According to the different concentrations of arachidonic acid, three groups were named as group A(0.1mg/ml), group B(1mg/ml), group C(10mg/ml). During 4 hours of slow infusion of the infusates(average 0.5ml in each side totally) central conduction time(CCT) was measured every an hour with contralateral median nerve stimulation bilaterally and cerebral blood flow(CBF) of white matter was measured by hydrogen clearance method every 2 hours. Finally the cats were sacrificed and specimens of edematous white matter obtained bilaterally at the coresponding points. Water contents were measured with vacuum freeze drying method. T2-weighted magnectic resonance images(MRI) and light microscopic studies were performed in a cat of each groups. The results were as followed ; 1) MRI and histologic findings showed that the infusion brain edema technique was efective in inducing interstitial edema, but the differences in the degree of edema formation between the right and the left sides were not siginificant in all groups. 2) There were no statistically significant difference between the water contents of the right and that of left in all groups. 3) Either infusion of arachidonic acid or physiologic saline in the white matter did not change regional white matter CBF in all groups. 4) The I-N1 interpeak latency was labelled as central conduction time(CT), and the baseline CCT was 5.83+/-0.52msec. 5) The differences of CCT between infusion group and noninfusion group were statistically significant in group C at 2, 3, 4hours(p>0.01) and the differerences of cct between arachidonic acid and physiologic saline infustion sites were statistically significant in group B at 4 hors, group C at 1 hour(p>0.05) and group C at 2, 3, 4hours(p>0.01) after eginning of infusion and the differences increased with time in group C(p>0.01). The results indicate that arachidonic acid does not have edemogenic properties during 4 hours infusion but may induce neurologic dysfunction as to increase the CCT in somatosensory evoked potential studies if it exists in the edema fluid of brain white matter.

A total of 72 cases of internal biliary drainage procedure has been done percutaneously at Departement ofRadilogy, Seoul Natinal Universtiy Hospital for recent 4 and half years since August 1981. Five different types ofinternal drainage including endoprosthesis were applied to various conditions with different obstruction levels.The different method of procedure in each type of internal drainage was described and the results were analysed.1. Among the clinical diagnosis in 72 cases, carcinoma of bile duct was in 37 cases as the most frequent one. Thenext was pancreas head carcinoma in 16 cases, followed by metastatic carcinoma and other disease. 2. Type Iinternal drainage, classical internal and external type with distal end in duodenum, was applied in 43 cases asthe most comon one. Type II, modification of type I with distal end in CBD, was applied in 17 cases. Type III,endoprosthesis distal end into duodenum, was applied in 7 cases. Type IV, endoprosthesis just across theobstruction in bile duct, was applied in 2 cases, Type V, combined type of any internal drainage with externaldrainage, was applied in 3 cases. 3. According to various obstruction level, prefered type could be selected. Forproximal obstruction type II and IV were preferred and for distal obstruction type III was chosen. However, type Icould be applied in any situation. 4. Early complication occurred in 9 cases(12.5%). Clinical imporvement withdecrease in bilirubin level was observed 17 of 21 cases in which follow-up data was available over 2 months. 5.Though the experience with those 72 cases it is recommended that appropriate type of internal biliary drainageshould be selected according to prognosis, obstruction level and clinical findings of each patient.
