BACKGROUND: There are a few methods, including primary intention, deleyed primary closure and secondary intention, to irpair several types of defects. But commonly-used primary intentional repair of a defect after surgical removal of a skin cancer by graft, flap or simple closure has several limitations such as the need of a skillful technique and various complications. OBJECTIVE: We undertook a secondary intention using occlusive dressing with a polyurethane film after skin cancer surgery instead of a primary repair and evaluated its efficacy, particularly in points of simplicity and safety, and cosmetic results. METHODS: We randomly chose 14 cases of skin cancers in 13 patients who had undergone simple surgical excision or Mohs micrographic surgery and then undertook secondary intention with polyurethane film after informed consent. Postsurgical wound care included cleansing with normal saline or boric acid, then covering the defect with antibiotic ointment, gauze and film a at regular intervals.

The t(3;21) (q26;q22) is associated with chronic myelogenous leukemia in blast crisis, leukemia evolving from therapy-related myelodysplasia, and with leukemia following other hematopoietic proliferative diseases. The t(3;21) is rare secondary aberration in blast crisis of Philadelphia(Ph)-positive chronic myeloid leukemia, which may be restricted to patients entering myeloid blast crisis. We report here in one case of chronic myeloid leukemia in blast crisis which reveals both t(9;22) (q34;q11), and t(3;21) (q26 ;q22). A 62-year-old male was diagnosed as chronic myeloid leukemia 5 years ago, received hydroxyurea therapy, and admitted because of gingival bleeding and fever. On examination, splenomegaly and leukocytosis with proliferated blasts(91%) in peripheral blood were noted. Bone marrow aspirate showed hypercellularity with severe blast proliferation(92.5%) which revealed all negative in peroxidase and PAS stain. Cytogenetic study of bone marrow cells showed the karyotype 46, XY, t(3;21) (q26;q22), t(9;22) (q34;q11), which might be suspected as myeloid blast crisis. Above finding was confirmed by the result of immunophenotyping(CD13 43.6%, CD34 68.2%, HLA-DR 91.6%). He received intensive chemotherapy, but still sustained proliferation of blasts was noted . The follow up cytogenetic study was as follows: 46, XY, 4(3;21) (q26:22), t(9;22) (q34;q11)/46, XY, t(3;21)(q26;q22), del(8) (q22), t(9:22) (q34,q11)/46, XY (16/3/1). He died soon from severe pancytopenia and sepsis.

PURPOSE: To describe CT findings and differential points of cystic thymic lesions. MATERIAL AND METHOD: We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. RESULTS: All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n=2), thick internal septa and calcifications(n=l). The cysts of teratomas manifested thick walls(n=9), internal septa(n=4), calcifications(n=6), fat components(n=4), and solid components(n=4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. CONCLUSION: The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, .and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

Body fluid Lactate dehydrogenase and its isoenzyme Measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudates in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudates and the activity of LD4 isoenzyme was also incereased compared with that of serum (P<0.05). 3. The inflammatory exudates of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity statistically compared with that of serum and malignant exudates (P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

During the period of 4 years from May, 1981 to April, 1985, 71 cases of obstructing subinfundibular muscular bundles of the right ventricle in congential cardiovascular anomalies were diagnosed by cariac catheterization and angiography at Hanyang University. The finding of right ventricular angiogram and degree of the right ventricular outflow obstruction, clinical data, electrocardiographic data and hemodynamic data were correlated irrespectively. The summary of this article is as follows. 1) The age of patients was ranged from 1 to 22 years old with a mean age of 8 years old. There were 39 males and 32 females with M:F ratio of 1.2:1. The incidence of obstructing subinfundibular muscular bundles of the right ventricle in congenital cardiovascular anomalies was higher with increasing age. 2) The associated cardic anomalies were as follows: 40 cases (56%) of isolated ventricular septal defect(VSD), 13(18%) of tetralogy of Fallot physiology, 7(10%) of patent ductus arteriosus(PDA), 3(4%) of pulmonary stenosis, 1 aortic stenosis, 1 double outlet of right ventricle(DORV), 1 trilogy, 1 ostium secundum defect, etc. The incidence of VSD with or without other associated cardiovascular anomalies was 56 cases(79%) out of 71 cases. 3) Maximum systolic pressure gradient between proximal and distal chamber of the right ventricle were under 25 mmHg in 32 cases, between 25 and 50 mmHg in 13 and above 50 mmHg in 26. Pressure gradients of all 7 cases with PDA were under 25 mmHg. 4) Correlative assesment of angiographic manifestation(2 indicies:Diameter of right ventricular outflow tract(systolic phase)/diameter of tricuspid valvular annulus(diastolic phase)=OT/TV, Diameter of right ventricular outflow tract(systolic phase)/Length of right ventricular diaphragmatic surface(systolic phase)=OT/RV) according to pressure gradient, OT/Tv and OT/RV values were lower the increasing pressure gradient, between proximal and distal chamber of the right ventricle. These were reverse correlations but coefficients of correlation(r) were-0.49and -0.48. Therefore, the degree of right ventricular outflow obstruction could be predicted, using 2 indices of right ventricular angiogram in individual cases, but could not be calculated accurately. 5) This indicated that pressuer gradient was also affected by technical errors, variable cardic anomalies, development of sinusoid, age and the other factors. 6) We assumed that non-invasive Doppler echocardiography could be useful in making the diagnosis and follow up of the patient with obstructing subinfundibular muscle bundles in right ventricle.

PURPOSE: The purpose of this study was to evaluate and compare the scintigraphic findings and diagnostic accuracy of double-phase Tc-99m sestamibi scan in primary and secondary hyperparathyroidism (HPT). MATERIALS AND METHODS: We retrospectively reviewed 16 cases of primary (18 lesions) and 11 cases of secondary HPT (44 lesions) who underwent Tc-99m-sestamibi scan before the surgical intervention. Scan was performed using LEM camera (Siemens, Germany) after the injection of 740MBq of Tc-99m sestamibi. Routine image consisted of baseline and 3-hour delayed images and each image was obtained using both parallel and pine hole collimator. The study population was 27 patients (male/female=5/22, age: 49.1+/-10.8). RESULTS: Eighteen lesions of primary HPT consisted of 13 adenomas and 5 hyperplasias, while all lesions of secondary HPT were hyperplasias. Among the case of primary HPT, we could detect all the lesions of 13 adenomas but only 2 lesions of 5 hyperplasias (40%) could be detected by double phase scintigraphy. Three cases of primary lesion showed decreased uptake in delayed images compared with baseline. The sensitivity, specificity, positive predictive value and accuracy of primary and secondary HPT were 58.8% (10/17), 83.3% (10/12), 83.3% (10/12), 75.9% (22/29), and 37.5% (15/40), 50% (2/4), 88.2% (15/17), 38.6% (17/44), respectively. Overall sensitivity, specificity, positive predictive value and accuracy were 43.9% (25/57), 75% (12/16), 86.2% (25/29), and 53.4% (39/73). There were no statistical difference between the weight of primary and secondary HPT lesion (p>0.05). CONCLUSION: Tc-99m sestamibi scan is fairly good modality to detect parathyroid lesion in patient with primary HPT before the surgical intervention. However, since some of cases may reveal decreased uptake in delayed image, a careful attention to the findings of baseline images may be helpful. Still the low accuracy of sestamibi scan in diagnosis of secondary HPT prohibits routine use of it for this disease.
