We analysed 58 patients who were admitted to the Department of Pediatrics, Yonsei University College of Medicine due to infectious mononucleosis from January 1986 to August 1992. Of 58 patients who had responses to IgM to EBV viral capsid antigen and/or heterophil antibody, 35 patients had hapatitis. Of 35 hepatitis patients, group I consisted of 22 patients who had only EBV infection and group II consisted of 13 patients who had hepatitis B markers or cytomegaloviral markers. The results were as follows: 1) Sex distribution revealed males to females to be 1.1:1. In the age distribution, the proportion of patients with 1 to 3 years of age occupied 40.9% for group I and 30.8% for group II. In non-hepatitis group, 73.9% of patients were in 2 months to 3 years of age. 2) The common presenting symptoms and signs of hepatitis group included hepatomegaly in 24 cases (68.6%), fever in 19 (54.3%), anorexia in 17 (48.6%), throat injection in 16 (45.7%), splenomegaly in 5 (42.9%), and cervical lymphadenopathy in 10 cases (28.6%) etc. 3) In group I, complications or combined diseases included pneumonia in 4 case, disseminated intravascular coagulation in 2 and 1 case in acute pancreatitis. Group II included 1 case of iron deficiency anemia, acute renal failure, peritonitis and pulmonary hemorrhage respectively. 4) Anemia (Hb: <10g/dl) was found in 3 cases (13.6%) for group I, and in 2 cases (15.4%) for group II. Leukocytosis above 10,000/mm3 was demonstrated in 15 cases (68.2%)for group I and in 3 cases (23.1%)for group II. The higher percentage (>15%)of atypical lymphocytes were found in 3 cases (13.6%)for group I and in 1 case(7.7%) for group II. Thrombocytopenia (platelet: <100,000/mm3) was detected in 1 case (4.5%) for group I and in 3 cases (23.1%)for group II. Total bilirubin above 1.0mg/dl was found in 6 cases (27.3%)for group I and in 5 cases(58.1%)for group II. 5) AST level of 100~500IU/L was found in 10 cases(45.4%)for group I, and in 5 cases (38.5%) for group II. AST level above 500IU/L was demonstrated in 1 case (4.5%) and in 3 cases (23.1%) respectively. The mean values of AST level were 253.4 455.3IU/L and 316.7 102.4 IU/L, respectively. 6) Elevated ALT level of 100~500 IU/L was found in 9 cases (40.9%)for group I and in 9 cases(69.2%)for group II. ALT level above 500IU/L was detected in 5 cases (22.7%)for group I and in 3 cases (15.4%)for group II. The mean values of ALT level were 356.9 561.2IU/L and 308.3 259.1IU/L, respectively. 7) Elevated ALT levels returned to normal values within 3 weeks in 14 cases (82.4%) for group I and in 6 cases (66.7%)for group II. The mean duration of normalization of ALT level were 17.3 14.1 days for group I and 19.9 14.8 days for group II. Our results suggest that it AST/ALT levels are elevated and hepatitis A, B, C markers are negative, or if sudden elevated AST/ALT levels are noted in hepatitis B carriers or a patient with cytomegaloviral hepatitis, Epstein-Barr virus infection should be suspected.

The plasma cholesterol, TG,LDG,HDL of 101 Korean hypertensive patients were measured to compare with plasma cholesterol, TG,LDL,HDL level of healthy people(control group). The plasma cholesterol level in hypertensive patients was 189.6+/-39.5mg% and was 188.7+/-33.7mg% in healthy people(P>0.5). The plasma TG level in hypertensive patients was 200.5+/-154.2mg% and was 116.1+/-32.4mg% in healthy people(P<0.05). The plasma HDL level in hypertensive patients was 44.6+/-15.5mg% and was 45.1+/-9.8mg% in healthy people(P>0.05). The plasma LDL level in hypertensive patients was 119.0+/-68.6mg% and was 98.1+/-53.4mg% in healthy people(P>0.05). The serum level of the total cholesterol, HDL and LDL cholesterol in the hypertensive patients group were not significantly different from the control group, but the serum level of the TG was significantly increased in the patients group. We thought that this difference of plasma TG level is due to exogenous TG in hypertensive patient group but further evalution in properties of TG is required.

Computerized Tomography can make accurate diagnosis in most of the mediastinal tumors and cysts by assessingtheir location, shape and internal architecture. Authors analysed and present CT findings of 89 surgically provenmediastinal tumpors and cysts that were studied and treated in Seoul National University Hospital during recent 5years. The results are as follows; 1. The most common tumor was teratoma(25 cases). Neurogenic tumor (20 cases),thymic tumor or cyst (16 cases), lymphoma(7 cases), bronchogenic cyst (6 cases), intrathoracic goiter (6 cases),pericardial cyst(3 cases) and cystic hygroma(2 cases) were next in order of frequency. 2. The most constant findings of teratoma was thick walled cystic area(100%), while pathognomonic fat and calcified density were seenonly in 52% and 48% of cases, respectively. 22 cases were located in anterior mediastinum, 2 cases were inposterior mediastinum and a case is in middle mediastinum. 3. There were 20 cases of neurogenic tumor consiting of6 neurilemmomas, 7 ganglioneuromas, 4 neurofibromas, 1 ganglioneuroblastoma, 1 neuroblastoma and 1 malignantschwannoma. Most of them were located in posterior mediastinum with exception of 2 neurilemmomas arising from leftvagus nerve and left recurrent laryngeal nerve in middle mediastinum. Cystic change was seen in 2 cases ofneurilemmoma and in a case of ganglioneuroma. Calcification was seen in 3 cases, of neuroblastoma, aneurilemmoma,and a ganglioneuroma. 4. There were 11 cases of thymoma showing homogeneous solid mass with speckeldcalcification in 4 cases and irregular cystic change in 3 cases. 2 cases were invasive thymoma and myastheniagravis was present in 4 cases. A case of thymolipoma and a case of thymic cyst were included. 5. Lymphoma(2Hodgkin's and 4 non-Hodgkin's) appeared as lobulated, matted mass in anterior mediastinum especially inprevascular area expnading bilaterally. 6. Intrathoracic goiter appeared as slingtly high density mass within termingled calcification and cystic area in 5 cases of secondary goiter and homogeneous high densitymass(100-110 H.U. in precontrast scan) in a case of primary goiter. 7. Among the 6 bronchogenic cysts, 3 werelocated in subcarinal area, 2 were above carina and one was in left hilar area. 3 cases showed high CT number morethan 70 H.U. and others showed water density. 8. 3 cases of pericardial cyst were located in right cardiophrenicangle and all of them showed water density. 9. 2 cases of cystic hygroma were located in superior mediastinum,with extension to lower neck and all of them showed water density.

Congenial mitral stenosis may be defined as a develpment abnormality of the mitral valve leaflets,commissures, interchordal spaces, papillary muscle,s annulus or immediate supravalvular area producing obstructionto left ventricular filling. Authors had experience of nine cases of congenital mitral stenosis confirmed by twodimenstional echocardiography, angiocardiography and surgery in recent 5 years since 1979, and analyzed them withemphasis on the angiographic findings. The results are as follows; 1. Among 9 cases, 6 patients were male and 3 were female. Age distribution was from 4 months to 11 years. 2. The types of congenital mitral stenosis were 1typical congenital mitral stenosis, 5 cases of parachute mitral valve and 3 cases of supramitral ring. 3. Angiographically typical congenital mitral stenosis showed narrowing of mitral valvular opening, parachute mitralvalve displayed single large papillary muscle with narrowed valvular opening and supramitral ring disclosedsemilunar shaped filling defect between left atrium and ventricle. 4. Associated cardiac and extracardiacanomalies of congenital mitral stenosis, as frequency wise, were ventricular septal defect, patent ductusarteriosus, coarctation of aorta, supra and subvalvular aortic stenosis, mitral regurgitation and double outletright ventricle. 5. Cardiac angiography is essential to diagnose congenital mitral stenosis, but the need of two dimensional echocardiography cannot be ignored.

Using immunohistochemical methods, the authors investigated the distribution of tubulin in normal skin and 31 skin tumors, including 11 benign skin tumors and 20 malignant skin tumors, In normal skin, tubulin was strongly expressed in basal cells of the epidermis, sebaceus celis and dermal nerves. Myoepithelial cells, ductalI cells of sveat ducts and outer root sheath cells of hair follicles stained moderat,ely. Lermal fi broblasts showed no staining. In benign tumors including keratoacanthoma, trichoepithelioma, and nevocellular nevus the strornal fibroblast.s were entirely tubulin negative as well as the turnor cells. In basal cell carcinoma, the stromal fibroblasts were negative',whereas tumor cells were weakly positive. In squarnous cell carcinoma(SCC), tumor cells weri, tubulin positive weakly, the degree of tubulin expression of its stroma1 fibroblasts tencied to be in proportional to the grade of malignanr.u. Tumor cells of malignant melanoma and nevocellular nevus were tubulin positive moderately bist the stromal fibrobla.sts were strongly positive only in the cases of malignant melanoma. These results show that the degree of the tubulin; expression in adjacent, stromal cells of epidermal tumors is in proportiona.l to that of their malignancy, These suggest that the expression of tubulin in fibroblasts surrounding tumor cells of malignant melanoma and SCC reflects a stromal alt,eration that might contribute to tumor in vasion, and play a role for cellular motility.

Patients with severe congestive heart failure due to rheumatic heart disease generally have both reduced cardiac output and increased pulmonary and systemic venous pressures. A study was therefore made of the use of vasodilator therapy with orally administered hydralazine, which acts on arteriolar resistance vessels and thus reduces afterload. 55 children aged from 4 years old to 15 year old were divided into two groups. Group I received oral hydralazine(4mg/kg/kay in 4 divided doses) in addition to digoxin therapy for mean duration of 10.5 months. Group II received oral digoxin only. The hemodynamic results using M-mode echocardiography, chest X-ray, and EKG between two groups were analyzed. 1) 4(78%) of 55 patients had only mitral valve involvement and another 12 patients had double valve involvement and all the patients belonged to functional class III or IV fo New York heart Association. 2) Left venticular end-diastolic dimensions and the height of R in V6 on EKG were not changed significantly in both groups. 3) Shortening fraction, LPEP/LVET, and RPEP/RVET were markedly improved in both groups, but the degree of improvement in group I was more significant than in group II. 4) 21(80%) of 26 patients in group I showed significant improvement in functional class(t=1.92, 0.05 Adolescent ; Cardiac Output ; Child* ; Child, Preschool ; Digoxin ; Echocardiography ; Electrocardiography ; Estrogens, Conjugated (USP)* ; Heart ; Heart Failure* ; Hemodynamics ; Humans ; Hydralazine ; Mitral Valve ; Rheumatic Heart Disease ; Thorax ; Venous Pressure

Partial lipodystrophy is an uncommon disorder primarily affecting women, with onset usually in childhood, characterized by slowly progressive, symrnetrical loss of aubcutaneous fat from the upper half of the body. We present a case of partial lipodystrophy in a 43-year-old woman with multiple depressed lesion on the face and reticulated atrophic lesions on the upper trunk and u]pper extremities. Typically, her face was the first part of the body so affected, giving it a characteristic cadeverous appearance, and gradu ally spreaded to the upper half of t2e body. Sirnultaneously, there was an accumulation of fat over the lower part of the body. She was generally otherwise well, although there had been an association with hyperpigmentation, hirsutism, arthralgia, thyroid disoraer, and low serum CR(45mg/dl), Riopsy specimens of iace and back showed lack of subcutaneous fat, but in the other section of the face showed hydropic degeneration of basal cells and inflammatory infiltrate in the dermis.

Keratosis punctata of palmar creases has been considered an uncommon variant of keratosis punctata, which itself is considered rare condition. Clinically our case, 32-year-old seaman, shows cup-shaped depression of the epidermis of varying size, from 1-3mrn in diameter, limited to the large flexor creases of the palms and digit. The histologic features are hyperkeratotic and slight acanthotic central epidermal depression without parakeratosis and loss of granular layer. A sparse mononuclear infilterate are seen arround the capillaries in the dermal papillas. No relationship to arsenical agents, syphilis, or genetic factors can be ascertained by history.

BACKGROUND: Extended-spectrum beta-lactamase-producing (ESBL) Klebsiella pneumoniae is an important cause of nosocomial infections in neonatal intensive care units (NICUs). This study aimed to reduce ESBL-producing K. pneumoniae in the NICU by using infection control measures. METHODS: We performed prospective surveillance cultures, monitoring, and education for infection control in the NICU between May and August 2011. Specimens were collected from all infants and the environment including stethoscopes, thermometers, ventilators, incubators, etc. The anterior nares and hands of healthcare workers were also screened. We inspected infection control practices and provided feedback. The level of infection control awareness was measured using a questionnaire. RESULTS: The level of awareness and performance of hand washing increased significantly after intervention (both P<0.001). The environmental management of healthcare providers also improved significantly (P=0.001). The yield of ESBL-producing K. pneumoniae from clinical specimens decreased gradually throughout the study period (30.4% in May to 12.6% in August). Central catheter-related K. pneumoniae bacteremia decreased from 1.3/1000 to 0/1000 catheter-days. CONCLUSION: Infection control measures including education, monitoring, and surveillance can lower the incidence of ESBL-producing K. pneumoniae in the NICU.
