The authors studied depression, using Zung's Self-Rating Depression Scale (SDS) in the subjects of 3,499 male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of SDS during the periods from January to February, 1986, and applied ANOVA and t-test on depression scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total depression scores between male and female students: male students scored 35.68+7.46, female students scored 38.93+7.26 (P<0.01). The depression scores relating to the items of indecisiveness, psychomotor retardation, decreased libido, and diurnal variation were relatively higher in both groups. One hundred and sixty-one male students (4.6%) showed seriously high degree depression scores of 50 or higher, while one-hundred and seventeen female students (8.8%) showed the same scores. Female students attending in liberal arts showed higher level of depression scores (P<0.01). There was a strong tendency toward higher depression scores in the students who were dissatisfies with their home atmosphere, college, department and familiarity of parents and those who had pessimistic views of self in the past, present or future in both groups (P<0.001).

Six patients with twenty histologically proven neurilemmomas of the extremities were studied using magnetic resonance(MR) imaging. The size, number, signal intensity on spin-echo T1WI(TR 500-650ms/TE 14-25ms)and gradient -echo (TR 200-600ms/TE 14-20ms; flip angle 25-30)image, enhancement pattern, detectability of nerve of origin, nerve-lesion relationship, and presence of a capsule were analyzed. The masses ranged from 1 to 12cm in longitudinal diameter and originated from the median nerve, ulnar nerve, sciatic nerve, radial nerve, and tibial nerve. All the nerve tracts except for those of 5 lesions, which could not be detected due to their small diameter, were visualized as low intensity tubular structures. All visible nerve tracts were situated along the periphery of the lesion and this finding was considered to be specific for neurilemmona. All neurilemmomas were isointense with the surrounding muscle on spin-echo T1WI and hyperintense on gradient-echo image. After a GD-DTPA injection, all masses showed moderate or marked enhancement and more prominent inhomogeneity than that on nonenhanced scan. In 19 out of 20 lesions(95%), a low signal intensity capsule surrounding the masses could be seen. Four of the six patients showed multiple masses, which was unusual as neurilemmoma usually arises as a solitary mass. In conclusion, the MR findings, especially the eccentric location of the mass lesion from the nerve of origin and the presence of a capsule, were useful in making a diagnosis of neurilemmoma of the extremity and that multiple neurilemmomas were not uncommon.

Now that ankylosing spondylitis is known to be relatively common, it is important that mild cases should be diagnosed earlier to avoid inappropriate investigation and unhelpful non-specific therapy and to improve social rehabilitation. However, difficulties in the diagnosis of ankylosing spondylitis are often encountered. To establish the clinical values of SPECT in ankylosing spondylitis, a study of radiologic evaluation, quantitative bone scan and SPECT have been carried out in 34 patients who were firmly suspected as having ankylosing spondylitis by other tests. This study showed that SPECT could improve the applicability of the imaging modality in the diagnosis and the assessment of disease activity and the capacity of early diagnosis in patients with ankylosing spondylitis. We believe that improved three dimensional localization in and around the sacroiliac joints by SPECT might overcome several diagnostic difficulties. Especially when radiographic abnormalities are not present in the early period, the diagnostic values of SPECT may be more potential.

STUDY DESIGN: The authors retrospectively analysed the difference of clinical natures in contained vs. ruptured HIVD. OBJECTIVE: To compare contained HIVD with ruptured HIVD in respect of clinical symptoms, signs and the result after surgery. SUMMARY OF LITERATURE REVIEW: In contained disc herniation, the disc material remains beneath tile intact outer annulus. But, once disc material penetrates through the limit of posterior annulus, it is a ruptured herniation or disc extrusion/sequestration. There is few report concerning the clinical characteristics related to type of herniation. MATERIALS AND METHODS: Forty-six patients, treated by open discectomy from March 1990 to December 1994, were followed up for minimum two years. The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR, and severity of radiating pain were periodically followed up on the predesigned protocol. Result: Twenty patients had contained disc and remaining 26 had ruptured disc. The mean age of contained disc was 31.4 years and that of ruptured disc was 43.3 years. In preoperative examination, 18/26 cases of patients with ruptured discs, developed pain in less than 3 months, compared with 7/20 cases of does with contained ones. Motor deficit was positive in 25/26 cases (96.2%) of ruptured discs and 12/20 cases (60%) of contained ones. 23/26 cases (80.8%) of patients with ruptured discs, had sensory deficit compared with 12/20 cases (60%) of those with contained ones. There was no significant difference in SLR and DTR change between ruptured and contained disc. CONCLUSIONS: Factors such as age, motor and sensory deficits and duration of symptoms had correlation with the type of herniation, but SLR and DTR change showed no statistical difference in this study. Clinical outcome showed no significant difference between two groups, but in ruptured group, the results were getting worse with the time goes. On the basis of this study, we concluded that the clinical symptoms and signs were different between the two groups, but surgical results showed no statistical difference.

We report the results of field operation of TELEACE system between Kyung-Pook National University Hospital and Ul-Jin Goon Health Care Medical Center from December, 1990 to September, 1991, which had been operated as a kind of Integrated Services Digital Nework projects by KOREA TELECOMMUNICATION Inc. Ul-Jin Goon Health Care Medical Center transmitted 414 plain radiographs to our hospital in speed of 9600BPS. Each image was composed of 1024X1024 pixelsX8 bits/pixel. In our hospital, the image files were displayed on high resolution monitor (1280×1024 pixets). Text files of image interpretations were transmitted to the health care medical center. The two radiologists who had interpreted the transmitted images, went to the health care medical center and read radiographic film with blind test method. We obtained the following results: false negative rate of 6.3%, false postitve rate of 2.4%, mean sensitivity of 81.4%, mean specificity of 96.3%, and mean accuracy of 91.3%. In predictive value of 0.05, there was no significant difference between results of these two types of radiographs. In conclusion, TELEACE system was valuable to the clinicians isolated from services of radiologists.

Purpura fulminans is a potentially disabling and life-threatening disorder characterized by acute onset of progressive cutaneous hemorrhage and necrosis on distal extremities, and disseminated intravascular coagulopathy. We experienced a case of purpura fulminans due to Streptococcus pneumoniae. A 42-year-old women presented with skin petechiae, ecchymosis and gangrene on distal extremities with laboratory evidence of DIC. The latex agglutination test with CSF was positive at Streptococcus pneumoniae. To our knowledge, this is the first report of purpura fulminans caused by Streptococcus pneumoniae in Korea.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.
