Intestinal metaplasia (IM) have long been thought to play a role in the pathogenesis of gastric intestinal adenocarcinoma, but not in that of diffuse cancer. We studied 20 normal gastric mucosa, 90 IM, 39 atypia (dysplasia or adenoma), and 51 adenocarcinoma to evaluate the expression of p53, erb B2, and H-ras p21 proteins and to assess the correlation with IM (esp. type III IM, revealing positive HID-AB/PAS for sulfomucin). Positive rate of HID-AB staining revealed an increased trend in comparison between IM, atypia and adenocarcinoma. It was the highest in mucinous carcinoma, but it was not correlated with positive oncoprotein expressions. Positive rates of oncoproteins revealed increased trends in comparison between IM, dysplasia or adenoma and adenocarcinoma in c-erb B2 and p53 (P<0.01). The positive rates were highest in intestinal adenocarcinoma (50.0% and 54.2%, respectively). Rates were lowest in biopsy tissue of IM (4.4% and 8.7%, respectively). The expression of H-ras p21 was not significant in gastric carcinogenesis. There was no significant correlation between oncoproteins and other clinical parameters, such as depth of invasion, differentiation, size and nodal metastasis of the tumors. Therefore, we suggest that p53 and erb B2 may play a role in the carcinogenesis of gastric intestinal adenocarcinoma.

This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

Wiskott-Aldrich syndrome is an X-linked combined immunodeficiency disorder characterized by severely decreased number of platelets which are small in size, eczema resembling atopic dermatitis and recurrent infection. The serum of the patient contains elevated concentrations of IgA and IgE, whereas the IgG level is usually normal and IgM level is decreased. The patients also shows skin test anergy and progressive T-lymphocytopenia. Bleedings and recurrent infections are the main causes of death and the patients usually die before age 10. Bone marrow transplantation is accepted to be the only radical therapy. We experienced a case compatible with Wiskott-Aldrich syndrome in a 5 year old male child who accompanied above clinical manifestations and laboratory findings.

Purpose: The results of a more than 10-year follow-up after total hip arthroplasties with circumferential and proximal porous-coated femoral stems were evaluated. Materials and Methods: Seventy-six patients (80 hips), who were operated on between Aug. 1991 and July 1994, were followed for more than 10 years after primary total hip arthroplasties using Multilock stems. The mean age at the time of the operations was 47.3 years old and the mean duration of follow-up was 12.3 years. The clinical results and radiological findings were evaluated. Results: The mean Harris hip scores improved from 54.7 points to 88.5 points at the time of the 10-year follow up. On the last follow-up radiograph, endosteal bone formation was observed in 70 hips (90%) and all femoral stems were biologically stable. Femoral osteolysis, which was linear in Gruen zone I and VII and mostly restricted to the proximal zones, was observed in 67 hips (84%), and no hip had distal osteolysis in the femur. There was no loosening, migration, or revisions of the stems. Conclusion: Total hip arthroplasties using circumferential and proximal porous coated Multilock femoral stems demonstrated stable osseous fixation and no distal osteolysis for a minimum 10-year follow-up; therefore, all stems were reported to have satisfactory outcomes. With improvement of cup design and liner wear, circumferential and proximal porous coating designs of femoral stems can be an alternative answer to mechanical failure due to aseptic loosening.

PURPOSE: We evaluated clinical results and incidence of exposures of orbital implants according to operative methods (enucleation or evisceration) and types of orbital implants. METHODS: We retrospectively reviewed the charts of 222 patients who underwent hydroxy apatite or Medpor(R) implantation after enucleation or evisceration and were followed up for more than 3 months from July, 1992 to November, 2001 at department of ophthalmology, Busan Paik hospital. RESULTS: In 222 eyes of 222 patients, who underwent hydroxyapatite and Medpor(R) implantaion, the exposure of implants occurred in 21 eyes (9.5%). In these cases, the exposure of implants occurred in 16 (12.8%) of 125 eyes with hydroxyapatite implantation and 5 (5.2%) of 97 eyes with Medpor(R) implantation. The exposure of implants occurred in 6 (7.1%) of 84 eyes after enucleation and in 15(10.8%) of 138 eyes after evisceration. The exposure of implants occurred in 12 (12.2%) of 98 eyes that used standard evisceration and in 3 (7.5%) of 40 eyes that used modified evisceration. CONCLUSIONS: The exposure of Medpor(R) implants was less than that of hydroxyapatite implants. But, it was influenced by types of orbital implants as well as operator and operative skill. There are few differences of exposure rate between the modified evisceration and enucleation.
