The first myelography with air was carried out by Walter Dandy in 1919, and the myelography with positive contrast medium was done by Sicard and Forestier in 1922. Since Pantopaque was adopted as a contrast material by University of Rochester group in 1944, it has been rapidly popularized. Although higher diagnostic accuracy has been made with a development of the diagnostic aids such as electromyography, discography, epidural venography and computerized tomography, myelography has been popularized in our country with electromyography. The authars have seen and studied 107 cases of herniated lumbar disc with respect to the diagnostic accuracy of myelographic examination from January, 1976 to December, 1981 at the department of Orthopedic Surgery, Yonsei University College of Medicine. The results were as follows: l. Of the 107 cases, 59 were found in the age of 20 to 40 years and the ratio of male and female was 2:l. 2. Fifty eight cases (54.2%) had no history of back injury, but 40 cases (37.4%) had sprain of the back and 9 cases had direct trauma history. 3. In all cases, plain X-ray and myelogram were taken. Among them 55 cases showed narrowing of intervertebral space in plain film, and 100 cases showed positive myelographic findings such as lateral indentation of dural sac (41 cases), hour-glass defect (30 cases), root sleeve defect (12 cases), block defect (10 cases) and combined defects (7 cases). 4. Sixty one cases which confirmed by operation, the most frequent level of disc herniation was in L4-5 space. Clinical diagnosis was correct in 57.4%, and myelographic accuracy was coincided with operative finding in 80.3%. 5. Twelve (19.7%) of the 61 cases showed discrepancy between myelographic and operative findings, and these 12 cases consisted of 5 cases of level discrepancy, 3 cases of false positive and 4 cases of false negative.

In 1960 Jacobson and Suarez introduced the operating microscope to vascular surgery and demonstrated the superiority of small vessel repair using magnification. The first clinical replantation of an arm in the western world was performed by Malt in 1962, and Komatsu and Tamai reported the successful replantation of a completely amputated thumb in 1965. To perform a digit or hand replantation, microsurgical anastomosis of blood vessels is absolutely essential to revascularize the severed part. Without accurate repair of bone, nerves and tendons in addition to vascular anastomosis, however, it is impossible to gain functional success when replanting a digit or hand. This is a difficult task because all structures must be reconstructed at the same level and time. Even if the repair of some structures has been postponed, the secondary reconstruction may also be troublesome due to circular scarring at the replantation level. Since replantation surgery has been popularized throughout the world in recent years, the replantation sucess rate has increased and the surgeons interest in functional reconstruction of replanted digits or hands has been stimulated. The authors have seen and studied 6 cases of upper Jimb and 20 cases of finger replantation from May, 1980 through January, 1982 at the department of orthopedic surgery, Yonsei University College of Medicine. The results were as follows: I. The average age was 20 years and the male to female sex ratio was 4.5:1. 2, The causes of injury are detailed as follows: electric saw(6); cutting machine(5); roller(4}; presser(2); stone(2); others(3). 3. The level of amputation in 26 replantations was as follows: thumb, 3 cases; index finger, 4 cases; middle finger, 9 cases; ring finger, 4 cases; palm, I case, wrist, 3 cases; forearm, 1 case; upper arm, 1 case. 4. The maximum ischemic times for successtul results were 16 hours in limb replantation and 22 hours in finger replantation. 5. Six limbs, with four complete and two incomplete amputations, have been replanted and all six limbs survived: Twenty digits, with nine complete and eleven incomplete amputations, have also been replanted and 6.5 cases of nine complete amputations and 10 cases ot eleven incomplete amputations survived. A total of 22.5 cases(86.5%) of replanted limbs and digits survived. 6. The results of joint motion, two point discrimination, sensory recovery and status of sweating due to recovery ot sympathetic nervous function following replantation were satisfactory. 7. In the early stage of our series, postoperative systemic heparinization was used in some cases, but recently we have achieved good recults without it. 8. Main causes of reattachment failure were tissue crushing and secondary thrombosis of the anstomosed vessels.

The term “non-ossifying fibroma of bone” was introduced by Jaffe and Lichenstein in 1942 to describe a distinctive benign lesion occuring near the ends of the long bones in young people, and the lesion was subsequently described by Hatcher as a developmental defect rather than a true tumor. This lesion was presented as a clear-cut entity on the basis of pathological, clinical and roentgenographic manifestations. The diagnosis of non-ossifying fibroma was made by the histopathological findings of the curetted tissues. The authors have seen and studied 5 cases of non-ossifying fibroma from February 1976 to September 1981. The average duration of follow up was 2.2 years, with a range from 0.8 to 5 years, and the results of treatment were as follows: l. Of the five cases, two were associated with pathologic fractures. 2. The sites of the lesions in all cases were the long bones in the lower extremity. 3 In all cases, the complaints were of only a few days or weeks duration before admission to the hospital, and no cases were discovered incidentally by roentgenographic examination. 4. Good results were obtained by treatment with curettage and bone graft.

Seborrheic dermatitis is a chronic recurrent inflammatory disorder presumed to be caused by increased sebaceous gland secretion, metabolic changes in the cutaneous microflora, and changes in the host immune function. Stellate ganglion block (SGB) is known to increase the blood flow rate without altering the blood pressure, heart rate, or cardiac output, to stabilize hypertonic conditions of the sympathetic nerves, and to affect the endocrine and immune systems. It is used in the differential diagnosis and treatment of autonomic nervous system disorders of the head, neck, and upper limbs. The authors report the first case of successful treatment of a patient with seborrheic dermatitis through repeated SGB trials.

PURPOSE: To evaluate the usefulness and diagnostic accuracy of turbo spin-echo(TSE) proton-density andT2-weighted images of meniscal tears of the knee. MATERIALS AND METHODS: We retrospectively evaluated thesensitivity, specificity, and accuracy of TSE proton density and T2-weighted images of meniscal tears confirmedarthroscopically or surgically in 47 patients(98 menisci). The routine TSE parameters used in all patients werethe dual echo sequence with sagittal proton density and T2-weighed images(4000/16, 90/5/2 [TR/effectiveTE/ETL/NEX]), and fat-suppressed coronal proton density and T2-weighted images. The chi-square test was used forstatistical analysis. RESULTS: The sensitivity, specificity, and accuracy of TSE proton density images for thedetection of meniscal tears were 93.9%, 93.8%, and 93.9%, respectively, in the medial meniscus, and 92.9%, 91.4%,and 91.8% in the lateral. On T2-weighted images the corresponding figures were 87.9%, 93.8%, and 89.8%,respectively, in the medial meniscus, and 64.3%, 91.4%, and 83.7 % in the lateral. CONCLUSION: With regard tosensitivity and accuracy, TSE proton density images of meniscal tears were superior to TSE T2-weighted images.

Developing Cushing's syndrome during pregnancy is rare because menstruation is irregular and hypercortisolism causes infertility. Developing Cushing's disease during pregnancy is very rare because there is even less ovulation than those with the adrenal adenoma. The clinical manifestations of Cushing's syndrome may easily be missed during pregnancy as the features of weight gain, hypertension, and hyperglycemia overlap with those that occur during a pregnancy. Diagnosing Cushing's syndrome during a pregnancy is complex because the biochemical features are obscured by the natural changes in the hypothalamic-pituitary-adrenal axis that occur during pregnancy. Having Cushing's syndrome during a pregnancy results in increased fetal and maternal complications, so early diagnosis and treatment are critical. We report the clinical and endocrine findings of a pregnant women with Cushing's disease who underwent transsphenoidal surgery after delivery.

PURPOSE: The purpose of this study was to describe the MR imaging and CT findings of intracranial inflammatory pseudotumors. MATERIALS AND METHODS: We reviewed the MR imaging (n=8) and CT (n=4) studies of eight patients (M:F = 4:4, mean age: 41 years) with pathologically proven intracranial inflammatory pseudotumor. The findings were then evaluated with regard to location, shape, MR signal intensity, CT density and degree of contrast enhancement of the lesion, surrounding parenchymal edema, adjacent bone change and the location of accompanying extracranial lesion. RESULTS: In two patients, the parietal convexity was involved unilaterally, with no extracranial mass, and in the other six, the middle cranial fossa was involved unilaterally and extracranial mass was present. The lesion also involved the tentorium in four cases, the cavernous sinus in four, the anterior cranial fossa in one, and the posterior cranial fossa in one. The location of extracranial mass was the mastoid and middle ear cavity in two cases, the infratemporal fossa in two, both the infratemporal fossa and paranasal sinuses in one, and the orbit in one. MR images showed diffuse dural thickening in all eight cases, leptomeningeal thickening in four, and focal meningeal-based mass in two. As seen on T1-weighted images, the lesions were isointense to gray matter in eight cases, and on T2-weighted images were hypointense in seven cases and isointense in one. Marked homogeneous contrast enhancement was seen in all eight cases. The lesions seen on brain CT, performed in two cases, were isodense. Adjacent brain parenchymal edema and the destruction of adjacent bones were each seen in five cases. CONCLUSION: The characteristic MR findings of intracranial inflammatory pseudotumors are(1) diffuse dural thickening;(2) a focal meningeal-based mass which on T2-weighted images is seen as hypointense; and marked (3) contrast enhancement : these findings are, however, nonspecific. In order to differentiate these tumors, an awareness of these findings is, however, useful.
