Clincal studies were made on 166 cases of spontaneous subarachnoid hemorrhage (SAH), were admitted to the keimyung university Dongsan hospital from January 1981 to March 1984. The age and sex distribution, causes of SAH, clinical symptoms and signs, computed tomographic (CT) findings, aneurysmal site, number and size, comparison between the highest density on CT findings and site of aneurysm confirmed by angiography,relationship between CT class and clinical grade, complication, and relationship between hospital course and clinical grade on admission were analysed. The results summarized as follow. 1. The most prevalent age group was between 41-60 years of age, and above 61 years, 31-40 years and below 30 years of age in the order of frequency. Male to female ratio was 43.4 : 56.6. 2. The most common causes of 100 cases of SAH confirmed by cerebral angiography was cerebral aneurysm (75 cases), and the other causes were unknown cause (16 cases), arteriovenous malformation (6 cases), moyamoya disease (3 cases) in the order of frequency. 3. The clinical symptoms on admission in the order of frequency were headache, nausea and vomiting, brief loss of consciousness, dizziness, seizure, and urinary incontinence. The neurological findings showed stiffneck, hemiparesis, cranial nerve palsies, papilledema and/or hemorrhage on the fundus, and Babinski sign in that order. 4. CT findings (158 cases) revealed typical high densities consistent with SAH in 125 cases (79.1%), associated with the low density (13 cases), and visible cerebral aneurysm (5 cases), while negative findings were 33 cases (20.9%). 5. The most common site of aneurysm among the 75 cases of SAH confirmed by the cerebral angiography was the region of the anterior communicating artery (AcomeA) which accounted for 30 cases (35.3%), and posterior communicating artery (PcomeA) and middle cerebral artery (MCA) 23 cases (27%), respectively, the internal carotid artery 5 cases (5.9%), the anterior ecrebral artery (ACA) 2 cases (2.4%), the posterior inferior cerebellar artery and basilar artery 1 cases (1.2%), respectively in the order of frequency. Among the 75 cases of cerebral aneurysms, single aneurysms were 67 cases (89.3%) and multiple aneurysms were 8 cases (10.7%). The most common size of the aneurysms was 6-10 mm (47 cases), and below 5 mm (30 cases), and above 10 mm (8 cases) in the order of frequency. 6. Sixteen out of 27 cases of AcomA aneurysms present the highest density on CT scan in the anterior hemispheric fissure, 9 out of 22 cases of PcomA aneurysms in syulvian fissure and 6 cases in suprasellar cistern, and all cases of MCA aneurysm (21 cases) in the ipsilateral aneurysmal site. 7. Comparison between CT grade by Davis (1980) and clinical grade by Hunt-Hesse (1968) revealed that the 93 of 94 patients (pts) with CT class 1 or 2 belong to under clinical grade 3, the 17 of 64 pts with CT class 3 or 4 belong to clinical grade IV or V, and the 17 of 18 pts with clinical grade IV or V belong to CT class 3 or 4. 8. The most common complication was the hydrocephalus (30.1%), and cerebral arterial spasm (24.1%), SIADH (8.4%), and rebleeding confirmed by lumbar puncture and/or CT (4.2%), in the order of frequency. 9. One hundred and four pts (62.7%) out of total 166 patient with SAH were improved, whereas 39 pts (23.5%) were not improved or signed out without clinical improvement, and 23 pts (13.8%) were died. The 81 (77.9%) of 104 pts who were improved belong to clinical grade I or II on admission, the 18 (78.3%) of 23 pts who were expired belong to clinical grade III or IV, and the 19 (48.7%) of 39 pts who were signed out without improvement belong to clinical grade III to V.

OBJECTIVE: To understand various morphologic types and locations of the sural nerve (SN) that are important for nerve conduction studies or nerve grafting procedures. The aim of this study was to describe the course and variations of the SN based on ultrasonographic findings for an adequate nerve conduction study. METHODS: A total of 112 SNs in 56 volunteers with no history of trauma or surgery were examined by ultrasonography. The location and formation of the SNs in relation to the medial and lateral sural cutaneous nerve were investigated. We measured the horizontal distance between the SNs and the midline of the calf at the level of 14 cm from the lateral malleolus, and the distance between the SNs and the most prominent part of the lateral malleolus. RESULTS: SN variants was classified into four types according to the medial and lateral sural cutaneous nerve; type 1 (73.2%), type 2 (17.9%), type 3 (8.0%), and type 4 (0.9%). The mean distance between the SN and the midline of the calf was 1.02+/-0.63 cm, the SN and the most prominent part of the lateral malleolus was 2.14+/-0.15 cm. CONCLUSION: Variations in the location and formation of the SN was examined by ultrasonography, and the results of this study would increase the accuracy of the SN conduction study.

PURPOSE: To determine computed tomography (CT) criteria for cardiomegaly. MATERIALS AND METHODS: We analyzed posteroanterior chest radiographs and CT scans of 200 patients (M:F=130:70, mean age 49 years old) that were performed on the same day. On plain radiographs, the cardiothoracic ratio (R) was calculated using a standard method. On CT, we measured the maximal cardiac width (D(c)) and the maximal thoracic width of a patient (D(t1)). A second thoracic width was measured at the same scan level of D(c). Thus, two cardiothoracic ratios were derived in one patient-D(c)/D(t1) (R(1)) and D(c)/D(t2) (R(2)). We analyzed the appropriateness of R(1) and R(2) in the diagnosis of cardiomegaly to establish criteria for the use of the cardiothoracic ratio (ROC curve). RESULTS: When cardiomegaly was defined as a value of R that was greater than 0.5, both R(1) and R(2) were useful indicators of cardiomegaly. For a cut-off value of 0.5 for the cardiothoracic ratio for cardiomegaly, the sensitivity of R(1) and R(2) was 84% and 68%, respectively, and the specificity of R(1) and R(2) was 72% and 86%, respectively. CONCLUSION: The cardiothoracic ratio on CT can be easily obtained by measurement of the maximal cardiac width divided by the maximal thoracic width at the same scan level. When the cardiothoracic ratio on CT is over 0.5, the presence of cardiomegaly can be suggested.

OBJECTIVE: To investigate the shoulder disease patterns for the table-tennis (TT) and archery (AR) wheelchair athletes via ultrasonographic evaluations. METHODS: A total of 35 wheelchair athletes were enrolled, made up of groups of TT (n=19) and AR (n=16) athletes. They were all paraplegic patients and were investigated for their wheelchair usage duration, careers as sports players, weekly training times, the Wheelchair User's Shoulder Pain Index (WUSPI) scores and ultrasonographic evaluation. Shoulders were divided into playing arm of TT, non-playing arm of TT, bow-arm of AR, and draw arm of AR athletes. Shoulder diseases were classified into five entities of subscapularis tendinopathy, supraspinatus tendinopathy, infraspinatus tendinopathy, biceps long head tendinopathy, and subacromial-subdeltoid bursitis. The pattern of shoulder diseases were compared between the two groups using the Mann-Whitney and the chi-square tests RESULTS: WSUPI did not significantly correlate with age, wheelchair usage duration, career as players or weekly training times for all the wheelchair athletes. For the non-playing arm of TT athletes, there was a high percentage of subscapularis (45.5%) and supraspinatus (40.9%) tendinopathy. The percentage of subacromial-subdeltoid bursitis showed a tendency to be present in the playing arm of TT athletes (20.0%) compared with their non-playing arm (4.5%), even though this was not statistically significant. Biceps long head tendinopathy was the most common disease of the shoulder in the draw arm of AR athletes, and the difference was significant when compared to the non-playing arm of TT athletes (p<0.05). CONCLUSION: There was a high percentage of subscapularis and supraspinatus tendinopathy cases for the non-playing arm of TT wheelchair athletes, and a high percentage of biceps long head tendinopathy for the draw arm for the AR wheelchair athletes. Consideration of the biomechanical properties of each sport may be needed to tailor specific training for wheelchair athletes.

The authors diagnosed a 54-year-old male as central mucoepidermoid carcinoma after undegoing clinical, radiologica l and histopathological examinations. The charateristics were as followed : 1. Clinically, the patient complained of the painless unilateral swelling of the left mandibular molar region and had a pus discharge through the fistula. Painful nodule was palpated on the scalp of the left frontal area and it was regarde d as a metastatic lesion. 2. Plain radiographs showed the ill-defined permeative radiolucent lesion. The osteolytic lesions were also detected in the cranial bone, number 9 and 11 ribs, scapula, and vertebral bodies. 3. The mandibular CT and PNS MRI showed the swelling of the left mandible and the enlargement of the several lymph node s of 1.5 cm in size. 4. Histopathologically, many solid epidermoid type cells were mixed with mucus-secreting cells and they were arranged i n duct-like structure. Most of them were epidermoid type, which indicates a high grade tumor. Mucins could be found in mucicarmine staining.

STUDY DESIGN: Retrospective case analysis. PURPOSE: We retrospectively evaluated the clinical and radiological outcomes of posterior sublaminar wiring (PSLW) and/or transarticular screw fixation (TASF) for reducible atlantoaxial instability (AAI) secondary to os odontoideum. OVERVIEW OF LITERATURE: Limited information is available about the surgical outcomes of symptomatic os odontoideum with AAI. METHODS: We examined 23 patients (12 women and 11 men) with os odontoideum and reducible AAI. The average age of the patients at the time of the operation was 44.2 years. The average follow-up duration was 4.5 years. Thirteen patients with anterior AAI underwent PSLW alone, while 10 patients with combined (anterior+posterior) AAI underwent PSLW and TASF. An autogenous iliac bone graft was used for all patients. Nine patients complained of neck or suboccipital pain, and 14 complained of myelopathy. RESULTS: Angulational instability (preoperative 18.7°±8.9° vs. postoperative 2.1°±4.6°, p<0.001), translational instability (16.3±4.9 mm vs. 1.8±2.2 mm, p<0.001), and segmental angle of the C1–C2 joint (23.7°±7.2° vs. 28.4°±3.8°, p<0.05) showed significant improvement postoperatively. Neck Visual Analog Scale score (6.2±2.4 vs. 2.5±1.8, p<0.05) and the modified Japanese Orthopedic Association (9.1±3.1 vs. 13.2±2.6, p<0.05) score also improved, with a recovery rate of 51.8%. Among the three patients who developed nonunion and/or wire breakage, one underwent revision surgery with repeat PSLW and was finally able to achieve fusion. The final fusion rate was 91.3%. CONCLUSIONS: PSLW and/or TASF provided satisfactory clinical and radiological outcomes in reducible AAI secondary to os odontoideum without significant neurological complications. Our results suggest that PSLW and/or TASF can be considered a viable surgical option over segmental fixation in highly selected cases of os odontoideum with reducible AAI.

Systemic sclerosis (SSc) is a chronic systemic disease that affects the skin, lungs, heart, gastrointestinal tract, kidneys, and musculoskeletal system. Although up to 90% of patients with scleroderma have been estimated to have gastrointestinal involvement, liver disease has been reported only rarely. A 51-year-old woman was hospitalized due to esophageal variceal bleeding. Her serum was positive for anti-nuclear antibody and anti-centromere antibody. Sclerodactyly was noted on both hands, and she had recently developed Raynaud's syndrome. Punch biopsy of the hand showed hyperkeratosis, regular acanthosis, and increased basal pigmentation in the epidermis, and thick pale collagenous bundles in the dermis. Liver biopsy showed chronic active hepatitis with bridging fibrosis. Consequently, she was diagnosed with liver cirrhosis due to autoimmune hepatitis (AIH) combined with SSc. AIH had subsided after administration of prednisolone at 40 mg per day. She received 5-10 mg/day of prednisolone as an outpatient, and her condition has remained stable. Patients with either AIH or SSc should be monitored for further development of concurrent autoimmune diseases. The early diagnosis of AIH combined with SSc will be helpful in achieving optimal management.

The term tumoral calcinosis in used to describe the deposition of nodular calcareous masses in the soft tissue around large joints, such as the hips, shoulders, and elbows. Although the cause has not yet been clearly determined, according to the hypothesis, failure of phosphorus metabolism in the proximal tubule in kidney, chronic renal disease and hyperparathyroidism may cause tumoral calcinosis. No cases of tumoral calcinosis treated with surgical resection in chronic renal failure patients on hemodialysis, so called uremic tumoral calcinosis, have been reported in Korea. The authors experienced the case of a 57-year-old woman with chronic kidney disease on hemodialysis who presented with a mass around the hip. We made a diagnosis using plain radiographs, magnetic resonance imaging, and computed tomography of tumoral calcinosis, and treated the patient successfully with surgical resection. We report on a case of uremic tumoral calcinosis with a review of the literature.
