The blow-out fracture can be reconstructed by various autogeneous and alloplastic material. Particulate, nonresorbable hydroxyapatite is currently one of the choice of implant material available for reconstruction of blow-out fracture. Hydroxyapatite is radiopaque ceramic, physically and chemically similar to enamel and cortical bone. It is a biomaterial derived from natural corals to use as a bone graft substitute. And we looked into the clinical usefulness of 2 type of hydroxyapatite with their advantages and disadvantages in reconstruction of blow-out fracture. 183 patients with blow-out fracture who underwent surgical reconstruction with two types of hydroxyapatite from March 1933 to July 1977 have been analyzed the results of surgical reconstructions, and have been followed up for more than a year. And the condition of formerly inserted hydroxyapatite was observed in the patients who needed 2nd surgical reconstruction due to the enophthalmos. The disadvantages of hydroxyapatite are fragility, size and contour limitations. In spite of these demerits, hydroxyapatite can be one of the prospective materials to reconstruct orbital floor. Through the clinical experiences for 5 years, we have not found any of complications of exposure, infection, and foreign body reaction. Low rates of diplopia, limitation of ocular movement, and enophtalmos was observed. Hydroxyapatite was well adherent to adjacent orbital bone in most patients who needed secondary reconstruction for enopthalmos. In conclusion, our study shows that the availability of hydroxyapattite in reconstruction of blow-out fracture is recommendable, with low complication rates. Hydroxyapatite important appears to be well tolerated, and provides useful alloplastic prosthesis with few problems in reconstruction of blow-out fracture.

PURPOSE: We observed the short-term outcome and associated complications of transscleral diode laser photocoagulation (TSDL) for acute proliferative retinopathy of prematurity (ROP) to evaluate the efficacy and safety. METHODS: 20 eyes of 10 infants with acute ROP were treated with transscleral diode laser photo-coagulation through conjunctiva by a single surgeon. Anatomical results and postoperative complications were main outcomes. Follow-up ranged from 11 to 40 weeks. RESULTS: In 1 eye (5%), there was a macular temporal dragging. In 19 eyes (95%), regression occurred after a single laser treatment with a flat retina. No significant anterior or posterior segment complications were occurred, even though there was a small amount of preretinal hemorrhage in 1 eye after laser photocoagulation. CONCLUSIONS: The results suggest that transscleral diode laser photocoagulation is a safe and effective alternative to cryotherapy or transpupillary diode laser photocoagulation in the treatment of ROP.

Aniridia is a relatively rare congenital anomaly and its incidence is about 1:100, 000.Main features of aniridia include congenitally partial or nearly complete absence of the iris and hypoplasia of optic disc and fovea. It is almost bilateral and occurred as an autosomal dominant trait.However, some patients develop both sporadic nonfamilial aniridia and Wilms 'tumor, and another group of patients is transmitted as an autosomal recessive trait. We observed aniridia in two generations, as mother and two daughters. They had cataract, nystagmus, neovascularization of corneal margin and pannus formation, as well as aniridia.We also found hypoplasia of optic disc and fovea in mother. We have operated on mother with phacoemulsified lens aspiration and posterior chamber IOL implantation in both eyes consecutively.The postoperative visual acuity following lens extraction improved, but was not corrected. In addition, intraocular pressure decreased.

A total of 48 cases of tuberculous lesion in the lymph nodes (43 cases), lung (3 cases) and soft tissue (2 cases), was subjected to fine needle aspiration cytology(FNAC). The age of the patients ranged from 19 to 77 year-old (average 33.6 years in age) and the male to female ratio was 1: 4. Thirty-four cases (70.8%) demonstrated distinct granulomatous reaction with or without caseation necrosis, nine cases (18.8%) showed no granulomas, but large amount of necrotic debris with numerous polymorphonuclear cells and histiocytes, and five cases (10.4%) revealed acellular material only. The overall AFB positivity in smears was 62.5%. In areas associated with granulomatous reaction and necrosis, AFB positivity was 55.8%, while it was 80.0% in cases with acellular necrotic material. There were 2 cases of parasitic infestation which could not be easily differentiated from tuberculosis based on aspiration smears only.

The PFC (Press Fit Condylar) knee was first implanted clinically in 1984 with retention of posterior cruciate ligament. Thereafter PFC modular version had been developed at 1988 with option of posterior cruciate ligament substitution and minor design changes. We classified the 170 patients, 252 knees which underwent the PFC total knee arthroplasty in the period from January 1988 to May 1995 into three groups. In group I, 62 patient. Had 93 total knee arthroplasties with insertion of the original PFC total knee prosthesis with retention of posterior cruciate ligament from January 1988 to October 1991. In group Iia, 51 patients had 74 total knee arthroplasties with insertion of the modular PFC total knee prosthesis with retention of posterior cruciate ligawient from November 1991 to May 1995. In group III, 57 patients had 85 total knee arthroplasties with insert.ion of the modular PFC total knee prosthesis with substitution of posterior cruciate ligament from November 1991 to May l995. Average follow-up periods were 7 years 5 months in group I and 3 years 2 months in group Iia and Ilb. Clinical and radiographic results were similar among the group I, Iia and llb except slight better scores in group Iia and Iib than group I, even though group IlI and IlI had short follow-up periods, Postoperative implant wear was developed at 5 knees in group I, 1 knee in group Iia and not developed in group Ilb. Implant loosening was developed at 1 knee only in group 1. Revisional arthroplasty was performed to 7 knees in group I, 1 knee in group Iia and not in group 1Ib. In conclusion, posterior cruciate ligament substitution group had no difference in functional results with the retention group. In the problem of implant wear, posterior cruciate ligament substitution group was superior to the retention group but similar in loosening.

It has been well known that variable complications oecur in multiple organs in chronic renal failure patients. Of them gastrointestinal complications are also variable including nausea, vomiting, gastritis, peptic ulcer, gastrointestinal bleeding, hepatitis, pancreatitis, telangiectasia, angiody- splasia etc. Of such complications the incidence of peptic ulcer had been known to be high, but after endoscopic study, the incidence of nonulcer mueosal lesion has been more common. So we evaluated tbe upper gastrointestinal mucosal lesion in chronic renal failure patients by endoscopic examination. 129 subjects(mean age, 42 years, creatinine clearance ratio<10 ml/min) participated in this study. After overnight fasting the subjects were premedicated with simethicon and benoxinate. The mucosal lesion was diagnosed by two endoscopists with observing the TV monitor of electronic endoscope Fujinon EVG-FP. Of the 129 patients, 78 patients(76%) were revealed to abnormal endoscopic finding. Of the abnormal findings, the incidence of gastritis was most common in 34.9%, and then gastic erosion, duodenal erosion, gastric petechiae, gastric telangiectasia, duodenitis, gastric ulcer, gastric xanthoma, esophageal erosion, duodenal ulcer, esophageal uicer in orders. There was no difference in abnormal finding according to therapeutic type. From our study, we conclude that the incidence of nonulcer mucosal lesion is higher than ulcer disease in chronic renal failure patient, moreover those lesion can be diagnosed only by endoseopy. So we think that upper gastrointestinal endoscopy is necessory for evaluation of upper gastrointestinal tract in chronic renal failure patient.

BACKGROUND: Obesity is the most common nutritional disorder in Western society as well as in Korea. Obesity results from a combination of genetic, environmental, and behavioral factors. MATERIALS AND METHODS: In an attempt to investigate the association of obesity with its candidate genes, beta3 adrenergic receptor (beta3AR) and uncoupling protein 2 (UCP2), we analyzed polymorphisms of beta3AR Trp64Arg and UCP2 -866G/A by PCR-RFLP analysis and the obesity-related phenotypes, including body mass index (BMI), fasting glucose concentration, and plasma lipid profiles in 750 subjects. RESULTS: The Trp64Arg polymorphism in the beta3AR gene was not statistically associated with the BMI. The UCP2 -866G/A polymorphism was significantly higher in obese than in non-obese subjects (P<0.05). However, the UCP2 -866A/A polymorphism was higher in the non-obese subjects. CONCLUSION: These results suggest that the UCP2 -866G/A polymorphism might be more useful for the prediction of obesity and obesity-associated diseases in Korean patients than the beta3AR Trp64Arg polymorphism.

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.
