PURPOSE: The purpose of this study was to identify the therapeutic effect of orbital reconstruction by transcaruncular approach on old medial orbital wall fracture. METHODS: We performed retrospective study on 23 eyes of 23 patients, who underwent orbital reconstruction with transcaruncular approach over six weeks after injury from July 1999 to August 2001. RESULTS: Nineteen cases had enophthalmos, preoperatively; five cases; 2 mm, seven cases; 3 mm, six cases; 4 mm, and one case; 5 mm, respectively. Postoperatively, we obtained enophthalmos less than 1 mm in 17 cases(89%). The exophthalmometry revealed that enophthalmos improved from 3.2+/-0.9 mm, preoperatively to 0.9+/-0.7 mm, postoperatively. Twelve cases had diplopia on the primary and downgaze, preoperatively. However, ten cases of them(83%) disappeared diplopia, postoperatively. Of the remaining two cases, one had persistent diplopia on the downgaze and the other had paralytic strabismus. CONCLUSIONS: We believe that the medial orbital wall repair through transcaruncular approach was a good way to correct enophthalmos and diplopia on old medial orbital wall fracture.

We report a case of reversible pituitary enlargement due to hypothyroidism in a 3-year-old male. OnT1-weighted images, the mass was located in the anterior lobe of the pituitary gland, and the signal intensity ofthe mass was equal to that of brain cortex. Gd-DTPA enhanced T1-weighted images showed homogeneous enhancement ofthe mass. After supplemental therapy with thyroid hormone for 8 months, MRI showed that the pituitary gland wasmarkedly smaller.

PURPOSE: Soft tissue or muscle adhesion to the Porous Polyethylene Sheet Implant (PPSI) can cause postoperative extraocular motility disturbance after orbital fracture repairs using PPSI. This study was designed to examine the efficacy of amniotic membrane transplantation in the suppression of fibrosis between orbital connective tissue and PPSI. METHODS: Twelve New Zealand white rabbits were grouped as A, B, and C and conventional PPSI were implanted between orbital connective tissue and orbital floor in group A; PPSI with a barrier surface (PPSI-B) in group B; PPSI with amniotic membrane transplantation in group C. The implants were harvested at 8 weeks postoperatively, and stained with Masson trichrome and hemaoxylin and eosin staining techniques. RESULTS: In group A, the PPSI demonstrated dense adhesion on both the soft tissue implant and the bone implant interfaces. A lot of fibroblasts were observed on the surface of PPSI. In group B, the PPSI-B demonstrated less fibrosis over the barrier surface, and less fibroblasts than in group A. In group C, the PPSI with amniotic membrane transplantation manifested least fibrous adhesion among three groups. CONCLUSIONS: In orbital fracture repair, amniotic membrane transplantation could reduce the fibrosis between orbital connective tissue and PPSI, and might prevent the postoperative extraocualr motility disturbance.

OBJECTIVE: To test if the intake of H2 receptor antagonists (H2-RAs) increases the risk of gastric cancer in the elderly. METHODS: The source population for this study was drawn from the responders to a questionnaire survey administered to the Korea Elderly Pharmacoepidemiological Cohort (KEPEC), who were beneficiaries of the Korean Medical Insurance Corporation, were at least 65 years old, and residing in Busan in 1993. The information on H2-RAs exposure was obtained from a drug prescription database compiled between Jan. 1993 and Dec. 1994. The cases consisted of 76 gastric cancer patients, as confirmed from the KMIC claims data, the National Cancer Registry and the Busan Cancer Registry. The follow-up period was from Jan. 1993 to Dec. 1998. Cancer free controls were randomly selected by 1:4 individual matching, which took in to consideration the year of birth and gender. Information on confounders was collected by a mail questionnaire survey. The odds ratios, and their 95% confidence intervals, were calculated using a conditional logistic regression model. RESULTS: After adjusting for a history of gastric ulcer symptoms, medication history, and body mass index, the adjusted OR (aOR) was 4.6 (95% CI=1.72-12.49). The odds ratio of long term use (more than 7 days) was 2.3 (95% CI=1.07-4.82). The odds ratio of short term use was 4.6 (95% CI=1.26-16.50). The odds ratio of parenteral use was 4.4 (95% CI=1.16-17.05) and combination use between the oral and parenteral routes (aOR, 16.8; 95% CI=1.21-233.24) had the high risk of gastric cancer. The aOR of cimetidine was 1.7 (95% CI=1.04-2.95). The aOR of ranitidine was 2.0 (95% CI=1.21-3.40). The aOR of famotidine was 1.7 (95% CI=0.98-2.80). CONCLUSION: The intake of H2-RAs might increase the risk of gastric cancer through achlorhydria in the elderly.
