Electrocardiographic findings in 18 cases of hypertrophic obstructive cardiomyopathy(HOCM) were compared with those in 20 hypertensives with disproportinate septal hypertrophy(DSH) and in 20 normal controls. In conventional 12 leads electrocardiograms, abmormal Q waves were seen only in 6 cases of HOCM and none in the remadinder. The R waves were tallest in leads V4 in 6 cases(33%) of HOCM, 3(15%) hypertensives with DSH, and 4(20%) of the controls. The correlations of the QRS voltages with echocardiographically measured left ventricular dimension, interventricular septal thickness and left ventricular mass were significant in the hypertensives with DST and normal controls, but insignificant in patients with HOCM. We conclude that these electrocardiographic differences in patients with HOCM from the others would be caused by uneven distribution of hypertrophied muscle mass in the left ventricule and/or by the altered depolarization in hypertrophied cardiac muscles.

In order to observe the development of ventricular arrhythmia during regional myocardial ischemia and reperfusion, especially under the presence or absence of ST-T electrical alternans on epicardial EKG. The proximal left descending coronary artery(LAD) was ligated for 20 minutes and then reperfused suddenly in twenty-three cats. Standard lead EKG(Lead??, chest lead EKG and epicardial lead EKG were recorded simultaneously during the occlusion and reperfusion respectively. During the ligation of LAD, STEA was observed in thirteen cats(56.5%). In occlusion period, the incidence of ventricular tachycardia in STEA positive group was significantly higher than in the negative group(p<0.01) and arrhythmic score was significantly higher(p<0.005) also In the reperfusion period the incidence of vefntricular fibrillation in STEA positive group was significantly higher than in the negative group(p<0.025). But there was the tendency to be higher in arrhythmic score of STEA positive group. There were no differences in heart rate, systolic left ventricular pressure, ST elevation and ST width in both groups. Most forms of ST-T of sinus rhythm before and after development of ventricular premature beat was low form(L). It was concluded that at the presence of STEA on EKG, the incidence of ventricular arrhythmia was more prevalent. So, STEA can be available as a marker of ventricular arrhythmia and prognostic factor.

A 62-year-old female was adrnitted to the Catholic University Hospital of Taegu-Hyosung with an intracerebral hemorrhage. She was operated on successfully, but developed bacterial pneumonia. She was then treated with sulperazone, tobramycin, and metronidazole for 1 month. After the antibiotic treatment, she suffered from a fever and bloody, mucoid diarrhea for 3 days, and was examined with a sigmoidoscope. The sigmoidoscopic examination revealed yellow patches of ulcerations and swelling covered with thick sero- sanguinous exudate in the distal transverse colon and sigmoid colon. A latex agglutination test for C. was performed on her stool, whereby difficile cytotoxin was negative, however, metronidazole resistant C. perfringens was isolated from anaerobic culture of the biopsied colon tissue. She recovered with 15 days using oral vancomycin treatment. The possibility of C. perfringens as a causative organism of pseuclomernbraneous colitis was discussed.

This study investigated the boundary of anserine bursa with the recommended injection site and shape on the insertion area of pes anserinus (PA), with the aim of improving clinical practice. Eighty six legs from 45 Korean cadavers were investigated. The mixed gelatin solution was injected to identify the shape of anserine bursa, and then the insertion site of the PA tendons was exposed completely and carefully dissected to identify the shape of the PA. The sartorius was inserted into the superficial layer and gracilis, and the semitendinosus was inserted into the deep layer on the medial surface of the tibia. The number of the semitendinosus tendons at the insertion site varied: 1 in 66% of specimens, 2 in 31%, and 3 in 3%. The gracilis and semitendinosus tendons were connected to the deep fascia of leg. Overall, the shape of the anserine bursa was irregularly circular. Most of the anserine bursa specimens reached the proximal line of the tibia, and some of the specimens reached above the proximal line of the tibia. In the medial view of the tibia, the anserine bursa was located posteriorly and superiorly from the tibia's midline, and it followed the lines of the sartorius muscle. The injection site for anserine bursa should be carried out at 20degrees from the vertical line medially and inferiorly, 15 or 20 mm deeply, and at the point of about 20 mm medial and 12 mm superior from inferomedial point of tibial tuberosity.

Right sided aortic arch is an uncommon congenital anomaly. It can be classified into three types, depending on the left aortic arch's degenerating pattern and the branching pattern of the great vessels. It can be associated with major congenital heart disease, depending on the type of right sided aortic arch. We report a case of an 18-years-old female who has right sided aortic arch with atrial septal defect (ASD). In our case, the patient had a right sided aortic arch and aberrant left subclavian artery, also she had ASD (ostium secundum) and moderate tricuspid regurgitation with pulmonary hypertension. The patient was successfully performed patch closure of ASD and tricuspid valve annuloplasty via midline sternotomy. The patient had uneventful postoperative course.

Adrenal myelolipomas are rare, benign tumors cornposed of mature fat and bone marrow elements. Most are small, asymptomatic tumors found incidentally at postmortem examination, Fine needle aspiration biopsy can be used to confirm the diagnosis and avoid an unnecessary operation. We report a case of adrenal myelolipoma confirmed by fine needle aspiration biopsy. A 77-year-old woman with complaining of upper abdominal pain for 2 days was found to have an adrenal mass. She took dexamethasone frequently for 3 years due to multiple arthralgia. Ultrasono-graphy showed a 6cm-sized, suprarenal mass and a stone in the gall bladder with thickened wall. Computed tomography and magnetic resonance imaging scan also presented a suprarenal mass. Endocrinologic results were within normal limits. Adrenal myelolipoma was confirmed by computed tomography-guided fine needle aspiration biopsy without surgery.

BACKGROUND AND OBJECTIVES: Non-invasive detection and characterization of plaque composition may constitute an important step in risk stratification and monitoring of the progression of coronary atherosclerosis. Multislice computed tomography (MSCT) allows for accurate, non-invasive detection and characterization of atherosclerotic plaques, as well as determination of coronary artery stenosis. The aim of this study was to determine the usefulness of MSCT for characterizing non-calcified coronary plaques previously classified by intravascular ultrasound (IVUS). SUBJECTS AND METHODS: Seventy-one plaques were evaluated in 42 patients undergoing MSCT and IVUS. Coronary plaques were classified as hypoechoic or hyperechoic based on IVUS echogenicity. On MSCT, CT attenuation was measured using circular regions of interest (ROI) and represented as Hounsfield units (HU). RESULTS: MSCT attenuation in hypoechoic plaques was significantly lower than it was in hyperechoic plaques (52.9+/-24.6 HU vs. 98.6+/-34.9 HU, respectively, p<0.001). When comparing CT attenuation between hypoechoic and hyperechoic plaques, 60.2 HU was the cut-off value for differentiating between the two, with a 90.7% sensitivity and a 78.6% specificity. CONCLUSION: MSCT might be a useful tool for non-invasively evaluating the characteristics of coronary artery plaques.

BACKGROUND: Mild iron deficiency anemia is known to be asymptomatic in most of the cases. In view of this, we studied response of the mild anemics to the maximal exercise loading test to learn whether or not they respond similarly to the normals. METHODS: The maximal exercise loading tests by Bruce's protocol were carried out in 22 female asymptomatic anemics with hemoglobin level of between 10.0gm/dL and less than 12.0gm/dL, and the results were compared with those of 44 non-anemic matched controls with mean hemoglobin level of 13.1gm/dL. The ages in both groups were in their 30's to 40's, and even the anemics were otherwise normal clinically and on various laboratory tests. RESULTS: There were no significant difference between two groups in VO2 max, HR max, VCO2 max and VE max and their derivatives including VT/VC and VE/MVV. CONCLUSIONS: Our results indicate that in patients with mild iron deficiency anemia, the cardiorespiratory response to maximal exercise loading is not different from the normals, and suggest that oxygen transport to tissues is not affected even at maximal exercise. probably by adaptive compensatory mechanism.
