BACKGROUNDs: A retrospective study was performed to define objective radiologic parameters in diagnosing epiglottitis on soft-tissue lateral neck radiographic study. METHODS: Parameters of soft-tissue structures(epiglottis width, third vertebral body width, ratio of epiglottic width to third vertebral body width) in 30 adult patients compared with those of age and sex-matched controls with foreign body in throat whose radiographic reading was normal. RESULTS: Epiglottis width of more than 11mm, ratio of epiglottis width(EW) to the third vertebral body width(C3W) of more than 0.5 were, respectively, found to be 100% sensitive and specific in differentiating between patients with and without epiglottitis. CONCLUSION: These preliminary results suggest that EW/C3W ratio of more than 0.5, EW of more than 11mm, respectively, may be useful in the diagnosis of epiglottitis in adult patients.

A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.

PURPOSE: We performed this study to evaluate the changes of total leukocytes and leukocyte types in CSF and peripheral blood (PB) in the early course of aseptic meningitis. METHODS: One hundred and eighty-nine children with aseptic meningitis, who were admitted to the Pediatric Department of Dong-A University Hospital during the period from June 1996 to October 1997 were included. Patients were divided into 4 groups by 12-hour intervals according to the time between the onset of illness and initial diagnostic lumbar puncture. We analyzed clinical pictures, total leukocytes and leukocyte types in CSF and peripheral blood (PB) in each group. RESULTS: 1) There was no significant difference in average total leukocyte counts in CSF between each group, and all groups were considered to be acute stage of illness. 2) The PMNL proportion of CSF leukocytes was 57.0+/-31.6% in group I, 44.1+/-32.3% in group II, 39.4+/-33.1% in group III and 26.9+/-27.9% in group IV. The PMNL percentage was significantly higher in group I than group III and IV and the proportion of patients with a predominance of PMNL was higher in group I than group III and IV (p<0.05) 3) The proportion of neutrophils in PB was highest in group I (76.5+/-15.7%) and significantly higher in group I and II than group III and IV (p<0.05). 4) Significant correlations were found between the proportion of PMNL in CSF and PB of patients (r=0.62, p<0.001) CONCLUSION: The change from a predominance of PMNL to a predominance of mononucler leukocytes was occurred 12-24 hours after onset, and there was a strong correlation between the proportion of neutrophils in CSF and PB.

Although many approaches have been attempted in the evaluation of liver size such as measurement of length,area and volume, the linear measurements have been used most frequently because of simplicity. We measured theliver size using 4 linear measurements for evaluation of hepatic pliability on plain abdominal film in the erectand the supine position. Our cases consisted of 125 persons who have no symptom or signs clinically and havenormal liver function test. The results were as follows: 1. The measurements of the liver size using diagonaldiameter(DD), oblique diameter of right lobe(OD), midline vertical diameter(MD) and height of right dome of theliver(HD) were ; 19.6+-1.8cm, 13.7+-1.6cm, 2.03+-0.4cm in the supine position; and 20.5+-2.1cm, 21.9+-2.1cm,15.4+-2.1cm, 1.87+-0.4cm in the erect position, respectively. 2. The differences of each diameter between erectand supine position were 0.9+-1.0cm in DD, 0.9+-1.0cm in OD and 1.7+-1.4cm in MD, and they were longer in thesupine position (p<0.001). 3. The HD was slinghtly longer in the supine position than in the erect position(p<0.001). 4. Among the 4 measurements, the largest difference of linear diameter between the erect and the supineposition was by MD. 5. We found the change or size and shape of the normal liver in the different position.

Six cases of nasal septum perforation were found among welders during periodic physical checkup in 1997. Considering the size, shape and margin, the perforations were assumed to have been occurred several years before of which the diameter were 8~15 mm. To investigate the cause of perforation, we reviewed the past history of preemployment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt, and analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we presupposed that the nasal septum perforations of welders were due to chronic exposure to low level hexavalent chromium and/or nickel, and report these cases with literatures review.

Objective: To investigate the incidence and survival rates of primary uterine carcinosarcoma (UCS) in Korea. Methods: From the Korea Central Cancer Registry, we identified patients diagnosed with primary UCS between 1999 and 2018 and collected their information, including age at diagnosis, Surveillance, Epidemiology, and End Results (SEER) summary stage, and treatment. Age-standardized incidence rates (ASRs) and annual percent changes (APCs) were calculated. Baseline characteristics and overall survival (OS) were compared by study periods, ages, and stages at initial diagnosis. Results: Overall, the incidence rate of primary UCS increased markedly during the time period: ASRs, 0.02 per 100,000 in 1999 and 0.25 per 100,000 in 2018 (APC, 13.9%; p<0.001). No difference in OS was observed between patients diagnosed in 1999–2008 and those diagnosed in 2009–2018 (5-year survival rate, 46.0% vs. 48.6%; p=0.871). Considering the mean patient age at diagnosis of UCS, we divided the study population into 2 groups. Patients aged ≥60 years had a more frequent prior radiation history, received less multi-modality treatment, and showed worse OS than those aged <60 years (5-year survival rate, 42.7% vs. 53.6%; p=0.001). In multivariate analysis, both old age at diagnosis (≥60 years) and the SEER summary stage were identified as independent poor prognostic factors for OS, whereas radiation history before the diagnosis of UCS was not. Conclusion The incidence rate of UCS in Korea increased significantly from 1999 to 2018. Advanced stage and old age (≥60 years) at diagnosis might be poor prognostic factors for survival, but not prior radiation history.

PURPOSE: To assess the accuracy of magnetic resonance(MR) arthrography in the diagnosis of anterior labral tear of the shoulder. MATERIALS AND METHODS: Between Semptember 1996 and February 2000, MR arthrography of the shoulder was performed in 281 patients with a history of shoulder pain or instability. Among this total, only 157 shoulders in 154 patients who underwent arthroscopy or open surgery 0 to 230 (average, 20.9) days after MR arthrography were included in this study; the subjects comprised of 150 males and 4 females with an average age of 23.3 years. MR arthrographs of these 154 patients were analyzed for the presence of anterior labral tears, and the findings were correlated with the arthroscopic and surgical findings. Anterior labral tear was classified as A to D according to its location, as determined by arthroscopy and surgery. (A=4 to 6 o 'clock direction, anteroinferior; B=2 to 4 o 'clock direction, central; C=12 to 2 o 'clock direction, anterosuperior; D= SLAP lesions). The retrospective analysis of MR arthrographs showing false-positive and negative findings was also undertaken. RESULTS: In the diagnosis of anterior labral tear, MR arthrography showed a sensitivity of 94%, a specificity of 90% and an accuracy of 91%. Anterior labral tears were confirmed by arthroscopy or surgery in 62 of the 157 shoulders (39%). Among 62 lesions, two (3%) were observed in area A, 32(52%) in area A+B, nine (15%) in area A+B+C, one(2%) in area A+B+D, 13(21%) in area A+B+C+D, two (3%) in area B+C, one(2%) in area B+D, and two(3%) in area C. Among ten false-positive cases, seven were focal lesions (two, three and two lesions in area A, B and C, respectively), and in the remaining three cases, located in area A+B, MR arthrography revealed thickening and deformation. All four false negatives were focal lesions (two in area A and two in area C). CONCLUSION: Other than in focal lesions, in which accuracy was relatively low, MR arthrography showed high sensitivity, specificity and accuracy in the diagnosis of anterior labral tear of the shoulder.

Massive pulmonary embolism is a major cause of morbidity and death in hospital. Most episodes of acute pulmonary embolism occurred from multiple emboli. When pulmonary embolism is suspected, the definitive diagnosis is pulmonary arteriography, but high degree of certainty can also be achieved with ventilation-perfusion scanning. The therapeutic modalities available for patients with acute pulmonary embolism are prophylatic and definitive therapy. Prophylatic therapy including anticoagulant with heparin is used to prevent further emboli episodes that might be fatal. Definitive therapy for pulmonary embolism including thrombolytic agents and pulmonary embolectomy attempts to dissolve and remove the resolution of the pathophysiologic sequelae of pulmonary embolism. We experienced a case of acute massive pulmonary embolism which occupied the pulmonary arteries bilaterally. Patient with orthopedic surgery one month before developedd dyspnea and chest tightness. Eventhough continuing enough amount of anticoagulant therapy, rapid hemodynamic deterioration and severe hypoxia occurred progressively. Urgent pulmonary embolectomy was succeeded and he has been followed up at out patient department.
