PURPOSE: To evaluate the usefulness and radiologic findings of CT in the diagnosis of orbital blow-outfracture. MATERIALS AND METHODS: Forty-four patients with orbital blow-out fractures diagnosed by clinicalfindings and CT were evaluated retrospectively. On CT images, we evaluated the site and frequency of fracture,herniation of orbital fat, extraocular muscle abnormality, intraorbital hematoma, and intrasinus hemorrhage. RESULTS: Forty-eight sites of orbital wall fractures were seen. Of these, 25(52.1%) were observed at the medialwall and 18(37.5%) at the inferior wall. Combined fracture of the medial and inferior wall was seen in fivecases(10.4%), and orbital fat herniation to adjacent sinuses in 25. Associated extraocular muscle abnormalitieswere seen at the medial rectus (n=20) and inferior rectus muscle(n=18). Intrasinus hemorrhage was seen in 15cases, and intraorbital hematoma in five. CONCLUSION: CT is a useful diagnostic modality for the evaluation oforbital blow-out fracture and associated soft tissue abnormalities.

BACKGROUND: Improvement of additional immunization rate is indicated as an important factor for effective immunization of diseases. In this study, the relationship between retention of mother and child health handbook and additional immunization rate of Japanese encephalitis and tetanus was examined. METHODS: A survey via questionnaire was performed against parents of students of middle schools in Gwangmyeong-si, Gyeonggi-do, and elementary schools in Seoul. Among 350 copies of the questionnaire delivered via post mail, 261 copies were collected and used in the analysis. The questionnaire included general features of subjects and their children, retention of the mother and child health handbook, and recognition of additional immunization of the Japanese encephalitis and tetanus vaccine. RESULTS: It was found that 80.8% of subjects answered affirmative to retaining the mother and child health handbook, and the group retaining the handbook had higher recognition rate of the need for additional immunization than the group that did not, for the Japanese encephalitis vaccine (83.2% vs. 51.2%, P < 0.001) and for the tetanus vaccine (66.5% vs. 31.7%, P < 0.001). Although the group retaining the handbook had a significantly higher additional immunization rate of the tetanus vaccine of 48.6% vs. 17.1% (P = 0.001), the immunization rate of the Japanese encephalitis vaccine did not show a significant difference (P = 0.231). The group recognizing the need for additional immunization of the Japanese encephalitis and tetanus vaccine had a significantly higher additional immunization rate than the counterpart (P < 0.001). CONCLUSION: It was considered that retention of the mother and child health handbook was related to recognition and execution of additional immunizations.

BACKGROUND/AIMS: The serum cytokeratin-18 (CK-18) has been suggested to be a surrogate marker of non-alcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the correlation between CK-18 and metabolic parameter in NAFLD patients. Correlation between CK-18 and macronutrient composition was also assessed. METHODS: A total of 212 subjects were recruited. Blood chemistry including fasting glucose, cholesterol level, AST, ALT, and CK-18 were compared. Data on calorie intake and carbohydrate consumption were acquired by five-day-diet diary using 24 hour recall method. RESULTS: Plasma CK-18 were markedly increased in patient with NAFLD compared with control group (420.4+/-282.3 vs. 313.6+/-179, p<0.001). Plasma CK-18 were positively correlated with systolic blood pressure (r=0.130), ALT (r=0.503) and negatively correlated with HDL cholesterol (r=-0.246). NAFLD patients with metabolic syndrome had higher CK-18 level than those without metabolic syndrome (484.0 vs. 372.1 U/L, p=0.021). When NAFLD patients were subdivided into two groups with CK-18 cut-off value of 400 U/L, patients with CK-18 level over 400 U/L showed higher body mass index (28.0+/-4.5 vs. 25.5+/-4.3), subcutaneous abdominal fat (283.5+/-172.2 vs. 195.7+/-147.8), AST (52.7+/-26.3 vs. 40.7+/-23.5) and ALT (102.0+/-52.6 vs. 61.2+/-32.2). Calorie intake (r=0.301) and carbohydrate intake (r=0.305) also showed positive correlation with CK-18. CONCLUSIONS: Plasma CK-18 showed positive correlation with metabolic parameters as well as calorie and carbohydrate intake when its cut-off value of greater than 400 U/L was used.

BACKGROUND: Nonspecific elevations of CK-MB, cTnT have been well known in patients with chronic renal failure(CRF) on maintenance hemodialysis. It has been suggested that recently developed cTnI seldom shows nonspecific elevations in these patients. Status of CRF patients can be divided into three groups: predialysis group, hemodialysis group and peritoneal dialysis group. Until now, most researchers have studied CK-MB, cTnT and cTnI only in CRF patients receiving maintenance hemodialysis. No previous studies have ever compared the differences of the nonspecific positivity of CK-MB, cTnT and cTnI according to the different status of CRF patients. METHODS: Nonspecific positive ratios of cTnI, cTnT, & CK-MB in were evaluated 20 predialysis patients, 13 CAPD patients and 20 hemodialysis patients. No one had had any evidence of myocardial ischemia during the previous 3 months before the study entry. The predialysis group was again divided into two groups according to the cut off level of serum creatinine of 3.0 mg/dl. Authors also compared the nonspecific positive ratios of cTnI, cTnT, CK-MB between diabetic CRF group and non diabetic CRF group. The sensitivity, specificity and false positive ratios of each enzymes were examined on and 6 hours after arrival in 21 CRF patients who visited the emergency room with the complaint of chest pain. RESULTS: 1) There were no nonspecific significant elevations of cTnI in CRF patients regardless of the status of CRF. But there were significant nonspecific elevations of CK-MB, cTnT in them. It was more marked in cTnT especially with the cut-off value of 0.1 ng/ml. 2) Nonspecific positive ratios of cTnT was significantly increased in diabetic CRF patients. 3) The sensitivity and specificity of cTnI were 100% and 93.3% each, which were significantly higher than those of CK-MB(83.3%, 66.7%) & cTnT(66.7%, 53.3%). CONCLUSION: In CRF patients, the nonspecific positive ratios of CK-MB, cTnT were higher than that of cTnI, and only cTnI did show significant specific elevations in all the CRF patients with acute myocardial infarction. It is likely that the status of CRF patients, dialysis mode, the sampling time point would not give significant changes in the nonspecific positive ratios of CK-MB, cTnT and cTnI.

Pichia ohmeri is a very rare pathogen of human infection. To date, two cases of P. ohmeri infection were reported worldwide. We have experienced a case of catheter-related P. ohmeri fungemia. The patient had been admitted due to cerebrovascular accident in rehabilitation center since August 1998. He had been bedridden due to previous cerebrovascular accident and undergone several episodes of nosocomial infection. Multiple antimicrobial agents had been used with central venous catheter for parenteral nutrition. On February 1999, he had developed fever and dyspnea. Vancomycin and imipenem were administered empirically and central venous catheter was removed on the impression of central venous catheter related infection. Blood culture and catheter tip culture grew P. ohmeri. He developed septic shock and finally led to death before the administration of amphotericin B.

Purpose: To derive the optimized intraocular lens (IOL) constants from automated and manifest refraction after cataract surgery in Korean patients, and to evaluate whether there is a difference in optimized IOL constants according to the refraction method. Methods: This retrospective multicenter cohort study enrolled 4,103 eyes of 4,103 patients who underwent phacoemulsification and in-the-bag IOL implantation at 18 institutes. Optimized IOL constants for the SRK/T, Holladay, Hoffer Q, and Haigis formulas were calculated via autorefraction or manifest refraction of samples using the same biometry and IOL. The IOL constants derived from autorefraction and manifest refraction were compared. Results: Of the 4,103 eyes, the majority (62.9%) were measured with an IOLMaster 500 followed by an IOLMaster 700 (15.2%). A total of 33 types of IOLs were used, and the Tecnis ZCB00 was the most frequently used (53.0%). There was no statistically significant difference in IOL constants derived from autorefraction and manifest refraction when IOL constants were optimized with a large number of study subjects. On the other hand, optimized IOL constants derived from autorefraction were significantly smaller than those from manifest refraction when the number of subjects was small. Conclusions It became possible to use the IOL constants optimized from Koreans to calculate the IOL power. However, if the IOL constant is optimized using autorefraction in a small sample group, the IOL constant tends to be small, which may lead to refractive error after surgery.
