PURPOSE: We studied results of the communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate in the elderly. MATERIALS AND METHODS: We studied 29 cases of communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate from April 2009 to April 2013. Fracture was classified according to AO/OTA classification. Postoperative clinical evaluation was performed with measurement of wrist range of motion (ROM) at last follow-up, modified Mayo wrist scoring system (MMWS), and visual analogue pain scale (VAS). Radiologic evaluation was performed with measurement of radial length on immediate postoperation and last follow-up, radial inclination, volar tilt and ulnar variance checked at the last follow-up using Sarmiento criteria. RESULTS: Using the MMWS, 13 cases were classified as 'good', 10 'fair', and 5 'normal'. The average wrist ROM was 88.5% for flexion, 92.2% for extension, 90.5% for adduction, and 94.0% for abduction. The average VAS was 1.7. On the last follow-up, average radius length, radial inclination and volar tilt did not show statistically significant improvement (p>0.05) compared to immediate post operation measurements, and according to Sarmiento criteria, 5 cases were classified as 'good', 14 'fair', and 7 'normal'. CONCLUSION: Treatment of severe communited distal radius fracture accompanied by bone defect with volar locking plate and allogenic cancellous bone graft is a satisfying and effective treatment method in the elderly.

Acinetobacter species encounters frequently with clinical specimens and now accounts for a substantial proportion of endemic nosocomial infections in Korea. Recent trends indicate that the antimicrobial resistant strains of Acinetobacter species are increasing. Sixty-one strains were isolated from specimens of patients suspected of nosocomial infections during 1991 to 1996. At present, phenotypic identification of Acinetobacter using biochemical test may not be reliable and resulted in the difficulty to clarify the source of infections and epidemiological study of hospital-acquired infections. Aware of the importance of rational taxonomic proposal for these isolates, correct species identification of these organisms by molecular typing method was carried out. A total of fifty-four strains of A. calcoaceticus-A. baumannii complex species which were identified to genospecies 2 and 13 by biochemical characteristics was subjected to identify by ribotyping using restriction endonuclease EcoRI, ClaI, and SalI. Of fifty-four strains, twenty-five strains were identified as A. baumannii (genospecies 2) and twenty-one strains as genospecies 13, and six strains changed to genospecies 3, and the rest two strains were confirmed as A. haemolyticus (genospecies 4). This result suggests that the ribotyping may be of value for identification of genospecies and epidemiological information of Acinetobacter strains.

The X-ray synchrotron is quite different from conventional radiation sources. This technique may expand the capabilities of conventional radiology and be applied in novel manners for special cases. To evaluate the usefulness of X-ray synchrotron radiation systems for real time observations, mouse fetal skeleton development was monitored with a high resolution X-ray synchrotron. A non-monochromatized X-ray synchrotron (white beam, 5C1 beamline) was employed to observe the skeleton of mice under anesthesia at embryonic day (E)12, E14, E15, and E18. At the same time, conventional radiography and mammography were used to compare with X-ray synchrotron. After synchrotron radiation, each mouse was sacrificed and stained with Alizarin red S and Alcian blue to observe bony structures. Synchrotron radiation enabled us to view the mouse fetal skeleton beginning at gestation. Synchrotron radiation systems facilitate real time observations of the fetal skeleton with greater accuracy and magnification compared to mammography and conventional radiography. Our results show that X-ray synchrotron systems can be used to observe the fine structures of internal organs at high magnification.

OBJECTIVES: This study was to investigate the prevalence of cognitive impairment and depressive symptomatology among the long-term institutionalized elderly people. METHODS: Mini-Mental state Examination-Korean version(MMSE-K), short portable Mental State Questionnaire(SPMSQ), Short version of Geriatric Depression Scale(SGDS), and the Center for Epidemiologic Studies Depression(CES-D) were administered to 169 elderly residents in an institution, 'Got Dong Rae'. RESULTS: One hundred fifty-three(males=72, females=79, and missing=2) completed the entire examination. Age ranged from 60 to 102 years and the mean of age was 74.17+/-8.27(males 71.76+/-8.14,females 76.14+/-7.78)years. Duration of education ranged from 0 to 16 years and the mean of duration of education was 3.04+/-3.93(males 4.13+/-4.23,females 2.01+/-3.38)years. The prevalence of cognitive impairment was estimated as 56.2% by MMSE-K < or = 23 and 26.1% by SPMSQ < or = 6. The prevalence of relatively definite cognitive impairment defined by MMSE-K < or = 19 was 25.5%, which was similar to the result achieved by using SPMSQ < or = 6. The prevalence of depressive symptomatology was estimated as 19% by SGDS > or = 10 and 23.5% by CES-D > or = 25. In the case of using SGDS > or = 8 as cutoff-point to screen mild as well as severe depressive symptomatology, the prevalence was 39.2%. It was identical to the result achieved by using CES-D > or = 20. Significant correlations were observed between MMSE-K and SPMSQ, between SGDS and CES-D, between MMSE-K and CES-D, between MMSE-K and SGDS, and between SPMSQ and SGDS. CONCLUSION: The prevalences of cognitive impairment and depressive symptomatology were high in institutionalized elderly people. This results suggests that more intensive mental health care in needed for long-term institutionalized elderly people.

BACKGROUND: Carotid cavernous fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus. The pathogenesis of spontaneous CCF remains unclear, although sinus thrombosis is known to be a predisposing factor for dural arteriovenous fistula. Because spontaneous CCFs are mainly of the dural type, we considered that thrombogenic conditions, such as, protein S deficiency might be associated with CCF. CASE REPORT: A 42-year-old woman complained of conjunctival injection and retro-orbital pain that first appeared 1-month before visiting our hospital. She had no history of head trauma or intracranial surgery. Exophthalmos and chemosis were observed in her left eye, which also had lower visual acuity and higher intraocular pressure than the right eye. Magnetic resonance images and cerebral angiography revealed a left dural CCF. Her protein S was low, at 41% (normal range: 70-140%), but other hematologic values related to coagulation were normal. Her symptoms were relieved after initial transvenous coil embolization. However, a newly developed sixth-nerve palsy was detected 4 days after initial embolization. Follow-up angiography revealed a minimal shunt, and thus transvenous coil embolization was repeated. Two days later, the ophthalmoplegia started reducing, and 1-month later it had almost disappeared. CONCLUSIONS: To the best of our knowledge, this is the first report of spontaneous dural CCF in a Korean patient with concurrent protein S deficiency. Interestingly, transient sixth-nerve palsy developed after transvenous coil embolization in this patient. This additional symptom caused by the residual fistula was relieved after additional transarterial embolization.

PURPOSE: To determine whether an analysis of two-phase spiral CT features provides a sound basis for differential diagnosis between gallbladder carcinoma and cholecystitis. MATERIALS AND METHODS: We reviewed a total of 89 cases of gallbladder carcinoma (n=35) or cholecystitis (n=54) in patients who had undergone two-phase spiral CT. For this, a GE Highspeed Advantage scanner (GE Medical Systems, Milwaukee, U.S.A.) was used. A total of 120ml of contrast material was injected at a rate of 2 -3 ml/sec. Arterial and venous phase scans were obtained 35 and 65 seconds, respectively, after the initiation of contrast infusion. All cases of gallbladder carcinoma and 468 of cholecystitis (of a total of 482) were confirmed by histopathology. We reviewed the two phase spiral CT features, analyzing and assessing thickness of the lesion, the enhancement pattern seen during the arterial and the venous phase, invasion of the liver, pericholecystic fat infiltration, dilatation of intrahepatic ducts, and other associated findings. RESULTS: Mean wall thickness was 12.6 mm in the gallbladder carcinoma group, and 7.2 mm in the cholecystitis group. The common enhancement patterns seen in gallbladder carcinoma were a highly enhanced thick inner wall layer during the arterial phase which became iso attenuated with adjacent liver parenchyma during the venous phase (16/35; 45.7%), and 2) a highly enhanced thick inner wall layer during both the arterial and the venous phase (8/35; 22.9%). The most common enhancement pattern in cholecystitis cases was an iso attenuated thin inner wall layer during both the arterial and the venous phase (44/54; 81.5%). Findings of intrahepatic mass formation by direct invasion (9/35), lymph node enlargement (12/35), and metastasis to other organs (7/35) occurred only in cases of gallbladder carcinoma. Dilatation of intrahepatic ducts was more frequent in cases of gallbladder carcinoma (18/35, 51.4%) than of cholecystitis (10/54, 18.5%). The incidence of pericholecystic fat infiltration and fluid collection was not significantly different between the gallbladder cancer and cholecystitis groups. CONCLUSION: Gallbladder carcinoma and cholecystitis varied in terms of wall thickness, enhancement pattern, and intrahepatic ductal dilatation, as seen on two phase spiral CT. Findings of liver invasion, lymph node enlargement and distant metastasis strongly suggested gallbladder carcinoma. These results suggested that gallbladder carcinoma and cholecystitis can be distinguished by analysis of their two phase spiral CT features.

Inflammatory myofibroblastic tumor in the lung is a rare tumor. The etiology is not clear. This tumor in children is a benign tumor rarely presented with local invasiveness, recurrence, distant metastasis or malignant changes can occur. The complete surgical resection is chosen as the optimal management. A 12-years-old boy visited the outpatient clinic with a 4 cm sized pulmonary mass in left upper lung field. The patient underwent left upper lobectomy. Histopathologically, inflammatory myofibroblastic tumor was confirmed. The patient was discharged without any problems and there was no evidence of recurrence during 3 months follow-up.
