1.Therapeutic Efectivity of Intralesional Injection of 5 - Fluorouracil to Basal Cell Carcinomas.
Korean Journal of Dermatology 1994;32(2):337-341
Basal cell carcinomas(BCCs) are usually treated with ablative proccdures, but a nonsurgical treatment would conserve tissue and obtain a better cosmetic out come as well as treat patients who refuse surgery or those who are not good surgical candidates. Because of inadequate drug penetration, low cure rates, high recurence rates, and adverse reactions, such as contact dermatitis, topical 5-fluorouracil(5-FU) is unsaitble to treat nodular BCCs. But, int,ralesional 5-FU has been reported to be effective for nodular BCCs. The efficacy and safety of intralesional injection of 5-FU have been evaluated for treatment of BCCs. The results revealed that intralesional injection of 5-FU seems to be effective in the treatment of various premalignant and malignant skin lesions as well as BCCs without side effects.

Twenty-three cases of the scaphoid fracture which were treated at the Department of the Orthopaedic Surgery, Catholic University Medical College during the period of december 1978 to december 1987 were analysed. The main purpose of this study was to clarify the significant factors affecting the union rate of the scaphoid fracture. The results obtained were as follows ; 1. The great majority of 23 cases was male with mean age 31. 2. Ulnar deviated stress oblique view with msking a fist was the most reliable means for diagnosing the fracture, location of fracture and stability of wrist after scaphoid fracture. 3. Union rate was obtained from 88.8% in undisplaced fresh fracture, 85.7% in displaced fresh fracture and 71.4% in old neglected fracture. 4. The union rate and associated factors affecting the prognosis after scaphoid frscture seems to be depended on the location of fracture, the severity of initial displacement of fracture fragments, time elapsed of treatment after fracture and accompanied injuries around the ipsilateral wrist.

PURPOSE: To verify the usefulness of left portal vein angle (LPVA) on CT scan in the diagnosis of liver cirrhosis and to compare its diagnostic value with that of caudate to right lobe ratio (C/RL ratio). MATERIALS AND METHODS: LPVA, an angle formed by a vertical line and a line connecting the center of the vertebral body to the umbilical point of the left portal vein, and C/RL ratio were measured on CT scans of 100 cirrhotic and 100 normal livers. Diagnostic values of LPVA and C/RL ratio were compared statistically. RESULTS: The mean of LPVA was 18.9 degrees(SD; 7.6) for normal livers and 25.8 degreesSD; 8.4) for cirrhotic livers (P<0.001). The mean of C/RL ratio was 0.47(SD; 1.10) for normal livers and 0.58(SD;0.14) for cirrhotic livers (P<0.001). When LPVA was greater than 30 degreesliver cirrhosis was diagnosed with 36% sensitivity and 92% specificity. When C/RL ratio was greater than 0.60, the diagnose of liver cirrhosis was with 41% sensitivity and 90% specificity. There was no significant difference of the diagnostic accuracy between LPVA and C/R L ratio in ROC analysis. CONCLUSION: Both LPVA and C/RL ratio are useful diagnostic indices of liver cirrhosis on CTscan. LPVA is more convenient to measure than C/RL ratio.

Journal of the Korean Surgical Society 1999;56(1):143-151
BACKGROUND: A desmoid tumor is a rare neoplasm of a mature fibroblast within an extensive collagen matrix. These tumors are classified pathologically as aggressive fibromatosis with local invasiveness, showing recurrences after surgical treatment, although they do not metastasize. Complete surgical excision without leaving a remnant tumor seems to be the primary treatment option, but these tumors often recur after resection. Therefore, alternative treatment strategies, including radiation therapy, nonsteroidal anti-inflammatory agents, anti-estrogen compounds, and cytotoxic chemotherapy, have been employed. METHOD: The authors report the clinical characteristics and prognoses after treatment for seven patients who were diagnosed as having desmoid tumors and who underwent surgical excision for therapy during the ten-year period from 1986 to 1997 at Keimyung University Dongsan Medical Center. RESULTS: There were two males and five females. The most common chief complaint was a slowly growing painless mass. The duration of the symptom before diagnosis was quite different from patient to patient. The locations in the trunk were scattered diffusely: the shoulder, the chest wall, the abdominal wall, the retroperitoneum, and the pelvic cavity. The tumors were well visualized by imaging techniques such as ultrasonograms, CT scans, and MRI. Four of the seven patients experienced recurrent tumors after surgical excision; two are dead. The tumors in the recurrent patients were excised incompletely at initial surgery. CONCLUSION: Although the uncommon, solid desmoid tumors which develop in the musculoaponeurosis of the trunk are benign pathologically, they were recurrent after surgical excision when the resection margin is incomplete. Therefore, complete excision is the only curative therapeutic modality.

To clarify the exact role of endomyocardial biopsy in the diagnosis and monitoring of adriamycin-induced cardiotoxicity and to observe the actual relationship between pathologic changes and cardiac dysfunction, a cross-sectional clinical study was conducted. Echocardiography was used to evaluate cardiac dysfunction in 18 patients who had received chemotherapy including adriamycin(mean dose : 410mg/m2 of B.S.A.) without clinical evidence of congestive heart failure, and in 19 normal controls. Six patients receiving adriamycin underwent 7 transfemoral endomyocardial biopsy procedures, and the specimens were evaluated by light and electron microscopy for evidence of drug-related cardiotoxicity. Indexes of cardiac systolic function obtained by M-mode echocardiography(left ventricular dimension, excursion of interventricular septum and left ventricular posterior wall, shortening fraction and ejection fracton) did not show any statistically significant difference between patients who received adriamycin and normal controls. In transmitral flow-velocity curves recorded by Doppler echocardiography with a 2.25MHz probe, the patients showed less E peak velocity and decreased E/A ratio compared with normal controls, which suggests left ventricular diastolic dysfunction in the patients who received adriamycin. All the specimens of the endomyocardial biopsy showed significant pathologic changes of adriamycin indnced cardiotoxicity which was characterized by myofibrillar loss and vacuolization of the cytoplasm. In 2 specimens, pathologic grade was II, while 5 specimens showed pathologic changes of grade III and further chemotherapy with adriamycine was not done in thse 5 cases. From these results it is suggested that pathologic changes precede the clinical onset of congestive cardiomyopathy in the patients receiving adriamycin and left ventricular diastolic dysfunction occurrs before ejection fraction falls to subnormal levels. We conclude that sequential endomyocardial biopsy is absolutely indicated for exact diagnosis and monitoring of adrinamycin-induced cardiotoxicity to prevent the development of irreversible and often fatal cardiomyopathy.

Aneurysms of the ascending aorta are relatively uncommon disorders which are located in ascending portion of the thoracic aorta. The commenest cause of aneurysms of the ascending aorta is arteriosclerosis, but syphilis, marfan syndrome, cystic medial necrosis, trauma, and aging of the aorta must also be noted as causes. We report a case with a aneurysm of the ascending aorta, 23 years old female, who was performed the open heart surgery because of ventricular septal defect with aortic insufficiency about 10 years ago.

Background:
Low-density lipoprotein cholesterol is an important marker highly associated with cardiovascular disease. Since the direct measurement of it is inefficient in terms of cost and time, it is common to estimate through the Friedewald equation developed about 50 years ago. However, various limitations exist since the Friedewald equation was not designed for Koreans. This study proposes a new low-density lipoprotein cholesterol estimation equation for South Koreans using nationally approved statistical data.
Methods:
This study used data from the Korean National Health and Nutrition Examination Survey from 2009 to 2019. The 18,837 subjects were used to develop the equation for estimating low-density lipoprotein cholesterol. The subjects included individuals with low-density lipoprotein cholesterol levels directly measured among those with high-density lipoprotein cholesterol, triglycerides, and total cholesterol measured. We compared twelve equations developed in the previous studies and the newly proposed equation (model 1) developed in this study with the actual low-density lipoprotein cholesterol value in various ways.
Results:
The low-density lipoprotein cholesterol value estimated using the estimation formula and the actual low-density lipoprotein cholesterol value were compared using the root mean squared error. When the triglyceride level was less than 400 mg/dL, the root mean squared of the model 1 was 7.96, the lowest compared to other equations, and the model 2 was 7.82. The degree of misclassification was checked according to the NECP ATP III 6 categories. As a result, the misclassification rate of the model 1 was the lowest at 18.9%, and Weighted Kappa was the highest at 0.919 (0.003), which means it significantly reduced the underestimation rate shown in other existing estimation equations. Root mean square error was also compared according to the change in triglycerides level. As the triglycerides level increased, the root mean square error showed an increasing trend in all equations, but it was confirmed that the model 1 was the lowest compared to other equations.
Conclusion
The newly proposed low-density lipoprotein cholesterol estimation equation showed significantly improved performance compared to the 12 existing estimation equations. The use of representative samples and external verification is required for more sophisticated estimates in the future.
