Seckel syndrome is a rare, autosomal recessive disorder of severe growth retardation and distinct craniofacial, orodental, and skeletal anomalies. We report hereby the first two Korean cases of typical Seckel syndrome who had characteristic symptoms of intrauterine growth retardation, small head, large eyes, sharp facial features (beaked nose, dysplastic ears and narrow face) with underdeveloped chin, dwarfism, severe mental retardation, and other malformation. We report two cases of Seckel syndrome with a brief review of related literatures.

BACKGROUND: After the World-Wide-Web(www) appeared, history has abruptly fallen in the new era of the Internet. In Korea, after the first medical internet site appeared, there was a major development in the WWW. But the quality and quantity of the web-page remains in infancy. Therefore, through the analysis of the Korean medical internet sites on present status, directions for development of Korean medical internet sites can be made. METHODS: From April 1st, 1999 to June 30th, 1999 in the Korean web sites, we visited 1044 sites. They included "Medmark Korea" representing medical search engine, "Eulji medical library" in the Eulji Medical College Hospital, and the medical sites of the "Yahoo Korea", "naver.com", and "simmani.com". Through this internet search, the information about locations, first publication year, classification by characteristics of homepage, speciality, web service form was obtained. Among these sites, acquireing from insufficient source further, questions were sent to the webmasters of 143 websites by e-mail. The questions included 7 items on the characteristic of webmasters, 8 items on the general characteristics of internet sites, 8 items on the contents, and their own comments. RESULTS: The occupation of webmasters was as follows: were physicians 94.4%, were male. According to age distribution, those in their thirties was 48.2%, and forties, 33.3%. Amone the 521 websites confirmed, there were 44 sites in 199 151 in 1996, 237 in 1997, and 79 in 1999. According to the distribution of location, metropolitan areas including Seoul, Inchon, Kyonggi occupied 68.9% among total. The main portion of the intentional visitors was ordinary people comprising 39.2%, members 9.8%, and physicians 7.7%. Concerning the purposes of publication, 38.7% of websites intended for health education to citizens, 31.0% for publicity of hospital or organizations, and 15.5% for exchange of information between members. For the most significant contents, 26.6% focused on the common-sense health issues, 35.7% on exchange of special medical information, 8.4% on education data for medical students, and 13.3% on publicity of hospitals. For the update interval, 22.0% renewed their sites within 1 week, 22.7% in 1 month, 23.4% in 3 months, and 20.6% in 6 months. For the effectiveness of homepage, the rate of `good' and `very good' response was 52.8%. CONCLUSION: Our investigation, showed that medical internet sites are lead by those in their thirties and forties. Web sites was concentrated to metropolitan areas where informational infrastructure was well developed. It is emphasized that efforts to informationalization by are needed by, governmental medical database systems should be established, and that the guidelines which enables validity of medical information should be set forth.

PURPOSE:The pathogenesis of short stature in growth hormone(GH) deficiency is believed to be based on the growth failure of growth plate chondrocytes by reduced growth hormone dependent insulin-like growth factor- I (IGF- I ) level in serum. Therefore, author studied the growth promoting effect of IGF- I purified from human serum on the chondrocytes, cultured from rat rib cartilage. METHODS:Rat rib cartilage were treated with type II collagenase and hyaluronidase and were cultured in Ham's F-12 culture media containing 10% fetal calf serum. Growth promoting effect of IGF- I was measured by MTT dye by adding 20ng/ml IGF- I purified by protein-diol 120 column(YMC Co, Japan) from human serum, to 1*104 cultured chondrocytes separated into each of 96 well culture vessel. RESULTS: 1) When elution time of biotin labeled IGF- I by protein pak 300sw column was compared to elution time of standard molecular weight, IGF- I exists as large complex of 150Kd and small complex of 50Kd with free 7Kd form in serum before acid treatment. After acid treatment, IGF- I exists as small complex of 50Kd with free 7Kd form. 2) IGF- I purified from blood samples, as compared to genetic engineering product standard IGF- I , showed good parallelism in competition inhibition curve by purity analysis utilizing IGF- I antibody, and thus it is assumed that complex protein as inhibiting factor for purified IGF- I does not exist. Furthermore, complex protein was not present on the Western ligand method using biotin-labeled IGF- I ligand after purified IGF- I transferred to nitrocellulose paper following SDS-PAGE electrophoresis. 3)IGF- I of 20ng/ml showed 30% growth promoting effect, when rat rib chondrocyte culture with Dulbeco's modified Eagles medium(DMEM) is considered to show maximum growth promoting effect, while with pure culture medium, DMEM, showing minimum effect. CONCLUSIONS:The results of this study suggest that IGF- I purified by this method assumes the role of growth promoting effect on the chondrocytes, and that the described method of radioimmuno assay of IGF- I also could effectively remove inhibiting protein complex, therefore allowing more accurate assay.

PURPOSE: To evaluate the clinical outcomes, complications and surgically induced astigmatism (SIA) after scleral fixation in patients with intraocular lens (IOL) or crystalline lens dislocation. METHODS: The present study retrospectively investigated the postoperative best corrected visual acuity (BCVA), refractory change, corneal astigmatism, clinical outcomes, and influencing factors of SIA in 57 eyes of 55 patients with a follow-up of 6 months after the IOL scleral fixation. RESULTS: In comparison of preoperative and postoperative 6 months, BCVA, spherical equivalent and astigmatism were significantly improved but corneal astigmatism was not and SIA (diopter, D) improved from 2.10 +/- 1.88 D to 0.86 +/- 0.73 D (p = 0.002). 4 eyes having redislocation were repositioned and 4 eyes having tilted IOL, 6 eyes having elevated intraocular pressure, 3 eyes having exposure scleral knots, 1 eye having endophthalmitis, and 1 eye showing macular edema were observed. At postoperative 3 months, the SIA of a large incision size (>3 mm) and small incision size (< or =3 mm) was significantly differented (p = 0.041). According to the location of scleral fixation, SIA at postoperative 1 month was significantly different but, was not different at postoperative 6 months. CONCLUSIONS: Surgical management of dislocated IOLs or crystalline lens resulted in significant improvement of visual acuity and absence of influencing SIA factors. However, location of scleral fixation and small incision size influenced corneal astigmatism.
