Iridocorneal endothelial syndrome is a disease characterized by corneal endothelial degeneration, corneal edema, peripheral anterior synechia, iris stromal change, and secondary glaucoma. This syndrome is considered to have three major variations: Chandler's syndrome, progressive (essential) iris atrophy, and Cogan-Reese syndrome. We experienced three cases of iridocorneal endothelial syndrome with transient intraocular pressure elevation.

PURPOSE: The aim of the present study was to evaluate the effect of Bio-Oss on bone formation in terms of healing period and type of membrane so that determine the most suitable condition for implant fixation in grafted maxilla. MATERIAL AND METHOD: Forty-five biopsy specimens from graft site were evaluated. Sinus lift was performed in the patients with reduced alveolar bone height(less than 5mm). The specimen was taken at the time of implant fixation, which was performed at least 5 months after the sinus lift procedure. All specimens were stained with HandE and Trichrome staining and evaluated histomorphometrically. RESULT: The results showed that Bio-Oss particle was in direct contact with newly formed bone in all cases. In the present study, the amount of newly formed bone and the residual bone substitute material were not statistically different according to various membrane and different healing period. There was no difference between the histological feature of the specimen of 5 and 31 months. No statistical significance was detected between male and female. CONCLUSION: The result implies that Bio-Oss does not seem to be resorbed over time regardless of the type of the membranes. The further investigation is needed to clarify this issue with the extended period of follow-up.

To investigate the risk factors and clinical characteristics of postrenal transplant diabetes mellitus (PTDM), we reviewed the records of 177 renal allograft recipients in Maryknoll Hospiatal whose allografts had functioned longer than 6 months. Nineteen patients (10.7%) developed PTDM at 5.0+/-7.8 (1-52) months; 9 (47%) of these within 1 month. PTDM patients were older than nondiabetic renal transplants (42+/-2 vs 37+/-1 years, P<0.05). Body mass index tended to be higher in PTDM (23.5+/-1.0 vs 21.8+/-0.3kg/m2, P=0.09). Number of acute rejections (0.6+/-0.2 vs 0.5+/-0.1) and serum creatinine at 1 year after transplantation (1.2+/-0.8 vs 1.3+/-0.3mg/dL) were not different. Fasting (103.6+/-10.4 vs 84.4+/-1.6mg/dL, P<0.05) and postprandial (189.2+/-24.8 vs 118.6+/-2.3 mg/dL, P<0.01) blood sugars, measured before transplantation, were higher in PTDM. CsA blood level at 1 month posttransplantation was higher in PTDM (350+/-34 vs 279+/-8ng/mL, P<0.05). Fasting serum insulin was significantly higher (28.2+/-12.2 vs 7.3+/-2.0 microunit/dL, P<0.05) and serum C-peptide tended to be higher in PTDM patients compared with euglycemic renal recipients (6.3+/-1.6 vs 3.8+/-0.9ng/dL, P=0.08). All the PTDM patients were treated by either insulin or oral agent; 15 of 19 required no treatment after 4.7+/-6.9 months. In conclusion, prevalence of PTDM was 10.7%. PTDM patients were older. Body mass index was tended to be higher. Fasting and postprandial blood sugars, measured before transplantation, were higher in PTDM. Faslting serum insulin was higher and C-peptide tended to be higher in diabetics. These results suggested that increased insulin resistance plays a major role in the pathogenesis of PTDM.

To understand the role of IGF2 gene in development of human ovary, IGF2 expression was detected by monoclonal antibody for IGF2 to its producted protein with immunohistochemical technique on human ovarian tissues. The results was as follows. IGF2 was highly expressed in ovum of mature follicle, IGF2 expression, however, was not high in granulosa and the cells. IGF2 was not highly expressed in ovum of primary follicle. Highly expressed IGF2 was found on corpus luteum and no expression of IGF2 was found in stroma and epithelial cells. These results suggest that IGF2 is important role in ovulation and in production of progesterone. Abnormal IGF2 expression may be concerned to carcinogenesis of ovarian tumor because most of all tumor from ovary is originated from epithelium.

OBJECTIVES: Extension of the standard model while retaining compliance with it is a challenging issue because there is currently no method for semantically or syntactically verifying an extended data model. A metadata-based extended model, named CCR+, was designed and implemented to achieve interoperability between standard and extended models. METHODS: Furthermore, a multilayered validation method was devised to validate the standard and extended models. The American Society for Testing and Materials (ASTM) Community Care Record (CCR) standard was selected to evaluate the CCR+ model; two CCR and one CCR+ XML files were evaluated. RESULTS: In total, 188 metadata were extracted from the ASTM CCR standard; these metadata are semantically interconnected and registered in the metadata registry. An extended-data-model-specific validation file was generated from these metadata. This file can be used in a smartphone application (Health Avatar CCR+) as a part of a multilayered validation. The new CCR+ model was successfully evaluated via a patient-centric exchange scenario involving multiple hospitals, with the results supporting both syntactic and semantic interoperability between the standard CCR and extended, CCR+, model. CONCLUSIONS: A feasible method for delivering an extended model that complies with the standard model is presented herein. There is a great need to extend static standard models such as the ASTM CCR in various domains: the methods presented here represent an important reference for achieving interoperability between standard and extended models.

The authors report a case of posterior fossa dural arteriovenous malformation with increased intracranial pressure. It was fed left occipital artery, posterior auricular artery, posterior meningeal branch of vertebral artery, and meningohypophyseal artery of left internal carotid artery. Treatment has been tried with transcatheter embolization using gelfoam and ivalon, intracranial clipping of feeders, ligation of external carotid artery, and radiation therapy. The unusual clinical manifestations such as visual disturbance and hearing impairment are discussed.

PURPOSE: The clinical effectiveness of monocanalicular or bicanalicular intubation with sequential probing was evaluated in patients over the age of 24 months with congenital nasolacrimal duct obstruction. METHODS: Patients over 24 months of age with congenital nasolacrimal duct obstruction who underwent monocanalicular intubation with sequential probing (19 patients, 20 eyes) or bicanalicular intubation with sequential probing (22 patients, 22 eyes) were studied. Success rates and complications were evaluated. Silicone tube was removed 6 months after surgery. Success was defined as no epiphora and no retention on fluorescein dye disappearance test. RESULTS: The success rate was 95.0% (19 eyes / 20 eyes) in the monocanalicular intubation group and complications included 7 cases of early tube dislodgement, which achieved successful outcome. The success rate was 82.6% (19 eyes / 22 eyes) in the bicanalicular intubation group and complications included 4 cases of punctal slitting, and 3 cases of tube extrusion. The success and complication rates were not significantly different between the 2 groups (p = 0.608, p = 1.000, respectively). CONCLUSIONS: In congenital nasolacrimal duct obstruction, the monocanalicular tube intubation group had similar success and complication rates to the bicanalicular tube intubation group. Silicone tube maintenance for 2 months in the monocanalicular group and for 3 months in the bicanalicular group was sufficient.
