PURPOSE: The purpose of this experiment was to evaluate the diagnostic ability of a CCD-based digital system (CDX-2000HQ) in the detection of incipient dental caries. MATERIALS AND METHODS: 93 extracted human teeth with sound proximal surfaces and interproximal artificial cavities were radiographed using 4 imaging methods. Automatically processed No. 2 Insight film (Eastman Kodak Co., U.S.A.) was used for conventional radiography, scanned images of conventional radiograms for indirect digital radiography were used. For the direct digital radiography, the CDX-2000HQ CCD system (Biomedisys Co. Korea) was used. The subtraction images were made from two direct digital images by Sunny program in the CDX-2000HQ system. Two radiologists and three endodontists examined the presence of lesions using a five-point confidence scale and compared the diagnostic ability by ROC (Receiver Operating Characteristic) analysis and one way ANOVA test. RESULTS: The mean ROC areas of conventional radiography, indirect digital radiography, direct digital radiography, and digital subtraction radiography were 0.9093, 0.9102, 0.9184, and 0.9056, respectively. The diagnostic ability of direct digital radiography was better than the other imaging modalities, but there were no statistical differences among these imaging modalities (p> 0.05). CONCLUSION: These results indicate that new CCD-based digital systems (CDX-2000HQ) have the potential to serve as an alternative to conventional radiography in the detection of incipient dental caries.

The Warthin tumor is a benign neoplasm that occurs mostly in the parotid gland. The tumor frequently occurs in the tail of the parotid gland. A 75-year-old man was referred to Wonkwang dental hospital with a chief complaint of swelling on the right submandibular area. Numerous salivary stones were observed in the right submandibular gland on computed tomography(CT). And the two tumorous lesions were incidentally found in the parotid gland bilaterally. The tumorous lesions showed homogeneous enhancement on the CT and intermediate signal intensity on both T1- and T2-weighted magnetic resonance (MR) images. This tumorous lesions also showed contrast enhancement on fat suppressed T1 weighted MR images. We report common CT and MR features of this case of Warthin tumor in the parotid gland with literature review.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

Among 334 thoracolumbar spinal injury patients who were admitted to this hospital from June 1972 to June, 1982, 66 patients with fracture and fracture dislocation of thoraco-lumbar spine which were defined as unstable clinically and radiologically were treated with surgical measures. The ratio between male and female was 7.3:1, the majority was found in third and fourth decade (46 cases, 69%), and the most common cause of injury was falling from a height (38 cases, 58%). The most common site of the injury was lumbar spine (29 cases, 44%) and the most common mechanism of injury was flexion-rotation (29 cases, 44%). Our surgical measures were Harrington rod instrumentation with either anterior or posterior fusion (25 cases, 38%), posterior wiring and fusion (14 cases, 21%), anterior decompression and anterior fusion (14 cases, 21%), posterior fusion (4 cases, 6%), anterior fusion and posterior fusion (3 cases, 5%) and etc. The average correction of displacement was 65% and the average correction of kyphotic deformity was 50%. The most remarkable correction was found at the cases of Harrington rod instrumentation (71%, 74%). Neurological deficit had already developed in 43 cases(65%) prior to operation, and the recovery was observed in 18 cases(42%). Most excellent recovery of neural deficit was found also at the cases of Harrington rod instrumentation (11 cases, 52%). We have analysed the results of these treatment and obtained following conclusions. 1. For the unstable fracture and fracture-dislocation of thoraco-lumbar spine with or without neural involvement, immediate surgical treatments were valuable to expect restoration of anatomical reduction and promotion of every possible recovery of neural function with spinal stability and fewest complication. 2. Fixation with Harrington rod instrumentation appears to provide better reduction and stability with neural improvement than other methods, and therefore early undertaking of rehabilitation activities is possible. 3. For the patients who are seriously compromised or require anterior decompression, immediate posterior reduction and fixation with Harrington rod instrumentation followed anterior decompression and anterior fusion of the involved segments at the eariest feasible time, we feel, is the treatment of choice.

There was increasing tendency to stabilize unstable cervical spine injuries surgically with the benefit of good stability of the spine, easy nursing care, early mobilization and therefore early rehabilitation. A clinical study was performed on 47 patients with fractures and dislocations of the cervical spine treated at the department of orthopedic surgery, Inje Medical College, Paik Hospital from Jan. 1975 to Dec. 1981. Following is the summery of the our findings. 1. The prevalent age distribution was between 3rd and 6th decade and the ratio between males and females was 10:1. The most common cause of injuries was automobile accident (70%). 2. The most common site of the injuries was C5-6 (34%) and the most frequent mechanism of injury was flexion-rotation type (47%). 3. In overall patients, neurologic damage was found at first examination in 73% and among these, complete paralysis below the injured level in 26%, incomplete paralysis in 11% and nerve root injury in 35%. 4. Among 47 patients, conervative treatment was performed on 9 patients, anterior spinal fusion on 8 patients, anterior spinal fusion with Halo application on 4 patients, posterior wiring with posterior spinal fusion on 16 patients and posterior wiring with anterior spinal fusion on 8 patients. 5. In the several methods of treatment, the posterior wiring with anterior spinal fusion revealed the best results, the correction rate of displacement was 92%, the correction rate of angular deformity 98% and neural recovery rate 72%. 6. The posterior wiring with posterior spinal fusion revealed good results in correction of displacement and angular deformity but required rigid external support for a long time. The anterior spinal fusion revealed poor results in correction of displacement(67%) and angular deformity(38%) and required rigid external support for a long time and had increasing tendency of kyphotic angle after operation. 7. In the treatment of unstable cervical spine injury, we thoughy that early posterior reduction with posterior wiring and followed anterior spinal fusion was ideal for accurate reduction, rigid stability and early mobilization with simple external support.
