1.Change in Pre-, Postoperative Endocrine Function and Growth Pattern in Patients with Craniopharyngioma.
Journal of Korean Society of Pediatric Endocrinology 1998;3(2):198-205
PURPOSE:Craniopharyngioma is one of the most important intracranial tumors in pediatric age which causes multiple pituitary hormone deficiencies. We have studied clinical characteristics in patients with craniopharyngioma, focusing on changes of endocrine function, change of growth pattern, and change of body mass index before and after surgery. In addition, we wanted to know the effect of growth hormone therapy on growth velocity and body mass index, and to identify contributing factors for spontaneous growth in spite of growth hormone deficiency. METHODS:A total number of 17 patients who were diagnosed as having craniopharyngioma at the Department of Pediatrics, Asan Medical Center during the period of January, 1991 to December, 1997 were included in this study. Retrospectively, we reviwed medical records as to their endocrine function tests and auxoloogical data before, after surgery. RESULTS: 1)The number of patients of male and female were 9 and 8 respectively. Mean age was 7.3+/-4.3 years. 2)Preoperatively, 3 patients were thyroid hormone deficient, 3 patients were corticosteroid deficient, and 3 patients suffered from diabetes inspidus. 3)Postoperatively, GH and TSH deficiency were found in 100%, ACTH in 88.2%, ADH in 82.3%, and LH/FSH in 60%, 53% respectively. 4) Mean growth velocity in 14 GH deficient patients without growth hormone treatment for 2 years were 3.5+/-2.4cm/year during the 1st year and 3.1+/-1.7cm/year during the 2nd year. Although height standard deviation score(Ht. SDS) was decreasing trend as -0.24+/-2.19 at diagnosis, -0.94+/-1.73 at 1 year later, and -0.76+/-1.76 at 2 years later, it was not statistically significant. To our suprise, 4 out of 14 patients achieved greater growth velocity than nomal in spite of growth hormone deficiency during the 1st year after operation. 5) Although the mean body mass index of 14 GH deficient patients without GH treatment was increasing trend as 17.9+/-3.5 at diagnosis, 19.0+/-4.5 at 1 year later, and 19.9+/-4.8 at 2 year later, it was not statistically significant. 6) The mean Ht. SDS increased significantly in 7 patients treated with growth hormone(P<0.05) for 2 years, but change of body mass index was not significant. 7) Comparision of postoperative serum prolactin levels and changes of body mass index between spontaneous growth and stunted growth group did not reveal significant difference. CONCLUSION: Since most patients with craniopharyngioma become multiple pituitary hormone deficient after operation, it is important to predict and detect pituitary dysfunction to manage it effectively. Although patients with postoperative GH deficiency responded well to GH treatment, further study is needed to clarify what are the main contributing or prognostic factors for spontaneous growth without growth hormone treatment.

2.Etiological Classifications of Children with Chief Complaint of Short Stature.
Journal of Korean Society of Pediatric Endocrinology 1997;2(1):1-9
Purpose : As the recombinant human growth hormone has been widely available, a lots of parents having short statured children are interested in promoting growth of them whatever the etiologies of short stature they have. However, the growth hormone therapy for growth-promoting effect is only justified in well-established indications such as growth hormone deficiency, fumer syndrome, and chronic renal insufficiency. This study was undertaken to classify the children with chief complaint of short stature by its cause and giving the basic epidemiologic data for it so that the size of population in which growth hormone is indicated can be estimated. Methods : According to Ranke's etiologic classification, we categorized the 579 children who visited our pediatric endocrinology clinic with chief complaint of short stature during the period of March 1994 to August 1996. In this prospective study, history regarding growth was taken, physical examination and laboratory tests including bone age, thyroid function, blood chemistry were carried out. The auxological data were analyzed. Additional chromosomal study or growth hormone provocative tests were performed when needed. Results : Out of 579 patients, 360(62.2%) were classified as normal and 127(21.9%) were classified as normal variants which consist of familial [74(12.8%)], constitutional [48(8.5%)], and mixed familial & constitutional short stature[5(0.9%)]. Pathologic short stature was found in only 80(13.8%). Those are growth hormone deficiency(28), Tumer syndrome(16), intrauterine growth retardation(14) in order. Other etiologies list varieties of dysmorphism, skeletal dysplasia, chromosomal disorders. Conclusions : This results suggest the vast majority of children with chief complaint of short stature are normal or normal variants. Only 7.8% of children who visited our clinic were indicated for growth hormone therapy.

3.Clinical Features and Natural Course of Hashimoto's Thyroiditis.
Journal of Korean Society of Pediatric Endocrinology 1999;4(1):94-99
PURPOSE:Although Hashimoto's thyroiditis is the most common cause of goiter in children and adolescents, it is not clear what proportion of patients become hypothyroid and which tests are the best predictors of this state. To determine whether these kinds of variations occur in the course of Hashimoto's thyroiditis and whether the size of the thyroid gland or immunologic markers correlate with the course or outcome of Hashimoto's thyroiditis are main objects of our study. METHODS:A total number of 48 patients who were diagnosed as having Hashimoto's thyroiditis at the Department of Pediatrics, Asan Medical Center during the period of January, 1992 to December, 1997 were included in this study. Retrospectively, we reviewed medical records as to their clinical and labaratory data. RESULTS:Thyroid function status at initial diagnosis of Hashimoto's thyroiditis were euthyroidism(33.3%), compensatory hypothyroidism(33.3%), overt hypothyroidism (27.1%), hyperthyroidism(8.3%) in order. Positivity of antithyroglobulin antibodies and antimicrosomal antibodies were 77.1% and 66.7% respectively. In 33 patients, 12(36.4 %) were on remission status after 3 years from initial diagnosis. Antithyroglobulin antibody titer was significantly decreased after 2-year follow up in remission group. Initial antithyroglobulin antibody titer and thyroid function status were not related to remission status after 3-year from diagnosis. CONCLUSION: About 36% of patients with Hashimoto's thyroiditis can be in remission after 3-year from diagnosis. Decrease of antithyroglobulin antibody titer is related to remission status. Further study is necessary to know what can be the predicting factors for early remission, for example, initial thyroid function status, initial antithyroid antibody titier, circulating immune complex, age, sex and size of thyroid.

A cross-sectional survey was conducted to determine the prevalence rate of scoliosis in elementary, middle and high school boys in May 1988. The study population included 1,393 male students in Pusan ; 463 students of 4th grade in two elementary schools, 543 students of 1st grade in one middle school and 387 students of 1st grade in one high school. The students of elementary school were screened with inspection by two physicians at the same time and the students of middle and high schools were screened with both inspection by the same physicians and 70mm chest X-ray. Positive students in any one of the two screening tests were measured for height and body weight and asked for the shoulder side on which he carries the school bag. The angle of curvature on X-ray film was measured by Cobb's method. The number of positive students in any one of the two tests were 15(3.2%) in elementary schools, 174(32.0%) in middle school and 92(23.8%) in high school. However, positive rates in both tests were only 2.2% for the middle school students and 2.6% for the high school students and among these students 1.1% out of total middle school students and 2.3% of high school students had a curvature equal to or greater than 5 degrees of Cobb's angle on 70mm chest X-ray film. There was a statistically significant association between the direction of spinal curve and the shoulder side on which one carries school bag among positive students in both screening tests (p<0.05). Mean height and body weight of 281 positive students in any one of two screening tests were compared with the Korean standard for the same age. Mean weight of elementary school students was nearly the same as the standard weight but the height was slightly shorter than the standard. However, both mean height and weight of the middle school students were lower than the standard while those of the high school students were higher. The prevalence rate of scoliosis for the 2nd 3rd grades of high school is presumed to be higher than that of the 1st grade of high school and the rate for girls will be even higher than the rate for boys of the same age. Thus, scoliosis seems to be an important school health problem. To prevent scoliosis, it is recommended to reduce the weight of school bag, educate the students to keep a right posture and exercise periodically.

Synovial sarcoma is a highly malignant tumor which arises from synovial tissue derived from mesothelium and its occurrence is very rare. Furthermore, congenital synovial sarcoma which developed from aggressive deposition of tumor cells during intra-uterine fetal life is extremely rare. Authors present a case of congenital synovial sarcoma which is found in the right ankle of one month old boy, because of its rarity of occurrence.

8.Funagating Malipant Melanoma after Rupture of the Globe.
Journal of the Korean Ophthalmological Society 1986;27(5):955-959
Malignant melanoma is a rare disease. On the average it occurs in from 0.02 to 0.06 of all eye-patients, that is, from 2 to 6 per 10,000. Malignant melanoma is rare among Negroes; the ratio of Caucasian to non-caucasian patients is 250: 1(Hogan and Zimmerman). The sex incidence shows a slight excess of males. Bilater al cases are exceptional. Hereditary influences are little in evidence. The very early stages of a neoplasm are difficult to come upon, but early growths have been found accidentally in eyes enucleated for other reasons. Extraocular entension may take place at a very early stage in the evolution of a malignant melanoma(when it was 2 X 3mm, Schultz-Zehden, 1905), but occurs most readily from the diffuse type of flat or ring-shaped growth. This does not usually occur directly through the sclera which forms a relatively efficient barrier unless the tumor becomes necrotic and the sclera participates in this process. As a general rule extraocular extension takes the path of least resistance along the channels made by the perforating vessels and nerves. A 42 year old Korean man was seen in our outpatient clinic complaining of a dark rapidly growing mass without pain OD for one month period. He was told that he may have intraocular tumor OD of unknown etiology by some ophthalmologist about 3 years ago. But since then he has never consulted with eyespecialist. Right eyeball including large mass was removed under general anesthesia and reported histopathologically to be malignant melanoma of epithelioid cell type. After surgery he received radiation therapy. Total 4,500 rad x-ray irradiation was applied on the right orbital area for 4 weeks.

Studies on the correlation between proliferative activity of biopsied specimen and pathologic findings of resected specimen have been carried out to find the prognostic factors. To estimate the proliferative activity, 100 cases of biopsied specimen of gastric adenocarcinoma were tested for the PCNA (proliferating cell nuclear antigen) and the AgNOR (argyrophilic nucleolar organizer region) by the immunohistochemical and histochemical stainings, respectively. The resected tumors classified by histologic type, differentiation, depth of invasion, and nodal metastatic status were followed by cell cycle analysis using flow cytometry. The PCNA LI (labelling index) were higher in well or moderately differentiated tumors (P<0.01) than the poorly differentiated ones and the aneuploid tumors (P<0.05) more than in diploid ones. However, there were no correlations among histologic types, depth of invasion, nodal metastatic status and PCNA LI. The AgNOR counts were higher in advanced tumor than in the EGC (early gastric cancer) (P<0.01). In cases with nodal metastasis, most of them showed the AgNOR counts higher than those without nodal metastasis. There were no correlations between the AgNOR counts and the DNA ploidy, histologic type, or differentiation. High PCNA LI and high AgNOR counts were shown in cases with advanced tumors (P=0.000) and nodal metastasis (P<0.05). No correlation was shown with the histologic type or differentiation. The results show that proliferative activity of the biopsied specimen of gastric adenocarcinoma is correlated with the differentiation and the invasion depth of resected specimen. Especially, better correlation is obtained by analyzing both the PCNA LI and the AgNOR counts than by analyzing each.

The blood bank of the Seoul National University Hospital has joined the U.K. National External Quality Assessment Scheme(NEQAS) for Blood Group Serology since 1992. We reported correct answers on all occasions for thirty-six samples tested for ABO, RhD typing, and direct antiglobulin test. Among 36 antibody screening and antibody,,identification tests, we missed one anti-S. Among 96 crossmatchings, we made 4 major errors and one minor error. It was interesting that all of the major errors we made were from the sample delivered in mid-summer. Since the items included in the domestic program for the external quality control of blood group serology are very limited in Korea, joining any international quality control program will be necessary for larger blood banks to assure quality of varirous blood bank tests being performed.
