Holter ECG monitoring is a continuous tape recording of a patient's electrocardiogram during ordinary activities and picks up hidden abnormalities in rate, rhythm or conduction. The authors delineated the types and incidence rates of arrhythmia in 32 normal Koreans by utilizing medical personnels and patients without evident heart diseases or symptoms, or significant systemic illness. Tracings and analysis were performed using 24 hour Holter monitoring processor(SCM 240, Fukuda, japan), auto-analyser (SCM-25), casette recorder(SM 24) and chrome tape. Results are as follows: 1) Portable 24 houre Holter ECG monitoring was performed in 32 persons(age range of 21 to 35) without cardiovascular disease, as defined by normal clinical and noninvasive cardiovascular examination. 2) During exercise, maximal heart rates ranged from 125.0+/-12.1/min and minimal rates from 96.7+/-5.8/min. During normal activity period, maximal and minimal heart rates were, respectively, 95.4+/-16.2/min and 62.6+/-6.3/min. Maximal sleep rates were 90.3+/-26.6/min and minimal sleep rates 57.4+/-12.4/min. 3) P-R interval decreased as heart rate increased. Transient first degree AV block was noted in 3 subjects(9.4%) and Wenckebach type second degree AV block in 2 subjects(6.3%). 4) Sinus tachycardia and bradycardia were observed in all subjects and sinus arrhythmia was more frequently noted during waking periods. Three subjects had episodes of sinus pause with maximum duration of 3.24 seconds. 5) In 13 persons(40.6%) having supraventricular premature beats, the frequency was 50.01+/-49.36/hr and in 14 persons having(44%) ventricular premature beats the frequency 26.33+/-18.83/hr. Transient ventricular tachycardia of 3 seconds' duration was observed in one subject under the extreme stressful environment. 6) ST segment elevation over 1mm was noted in 5 subjects(15.6%), of whom one had a nocturnal chest pain and ST segment depression over 1mm in 2 subjects. T wave inversion was also found during exercise(3.1%) and during sleep(9.4%).

The authors investigated serial changes of bacillary and granularity indices from 49 previously non-treated lepromatous leprosy patients under DDS therapy during 24 month period, and the following results were obtained. 1) Pretreatment bacillary index was highest on eye brows, and chins, ear lobes, arms, legs, backs in decreasing order. The proportion of fall of B.I. during therapy showed similar tendencies in each site of smears, the average decrease being 1. 2 in the first year and 0. 8 in the second year. 2) The average granularity index before therapy was 2. 5, the rise of G.I. was rapid during first 12 months, slower during next 6 months, and no significant changes were seen during last 6 months. 3) The changes of G.I. were faster and more sensitive to therapy than that of B.I. Therefore, it. seems more valuable assesing the response of therapy, drug resistance, prognosis, etc 4) 300 mg of DDS per week appears to be sufficient for maintaining the therapeutic dosage.

30 patients with essential hypertension were treated with diltiazem (Herben(R))significantly decreased both systolic and diastolic blood pressuer and heart rate. Mean decrease in systolic & diastolic blood pressuer were 38.0+/-4,5mmHg and 16.3+/-2.3 mmHg respectively and mean drop in heart rate was 17+/-2 beats/mm. The side effects of diltiazem (Herben(R)) were mild headache, fatigue and pruritus, but those were insignificant. Diliazem may be of benefit to hypertensive patients, and particularly useful when hypertension occurs in association with coronary artery disease.

6 cases of nevus sebaceus of Jadassohn were reported and its literatures were reviewed. It is thought to be rather rare disease in this country. Two of the cases were seen within the age of 2 years and showed the clinical pictures of early stage. The remaining 4 cases were the clinical pictures of late stage showing verrucous lesions. All cases developed the lesions in the scaIp except case 6 which appeared on anterior neck. One of thc cases was associated with syringocystadenoma papilliferum but none of the cases show any association of basal cell carcinoma.

Hypereosinophilic syndrome is characterized by marked eosinohia and eosinopbilic infiltrition of various organ-systems without any identifiable underlyin sathologic conditions such as hypersensitivity, drug eruption, parasitic infestat,ion, malignant tuinc, and autoimrnune and infectious d iseases. A 31 year-old male had weight loss, abnormal peripheral cirrultiction both extremities and two distinct skin lesions. One showed rice sized, erythematous follicular popules on both extremit.ies and trunk and the other showed a walnut sized, gangrenous ulcer on the left 2nd finger tip. The patients skin lesions and circulation defect. improved after retrnent with steroid and the blood eosinophilia returned to normal.

Left ventricular hypertrophy is a compensatory response to hemodynamic overload secondary to an increased systemic resistance. This increase, however, is not the only cause of hypertrophy, and there are other factors which can have a significant effect on its incidence. To determine whether chronic antihypertensive therapy by enalapril modifies the cellular and subcellular changes of left ventricular hypertrophy observed in spontaneously hypertensive rats(SHR), 20-weeks-old SHR were treated for 22 weeks with enalapril(2mg/kg) and compared with normotensive Wister-Kyoto rats and not-treated SHR. Systolic blood pressure in enalapril-treated SHR was significantly lowered after 22 weeks compared with that of untreated control SHR group. Myocytes were reduced in size and fibrination seen in cardiac muscle fibers of control SHR was decreased in treated SHR group. Myofibrils appeared to be irregular in shape and myofilaments are decreased in control SHR but in enalapril-treated SHR the diameter and length of the myofilament became turned to regular forms. These results suggest that, enalapril, angiotensin converting enzyme inhibitor, may regress hypertrophy and some subcellular changes may be modified by enalapril.

BACKGROUND: This is a retrospective, descriptive study, evaluating the observed agreement between 1996 & 2002 Centers for Disease Control and Prevention (CDC) definitions of nosocomial pneumonia (NP) for medical intensive care unit (MICU) and surgical intensive care unit (SICU) patients. METHODS: A total of 476 adult patients who were over 15 years of age and had been admitted to the MICU & SICU of a university hospital between August 1, 2005 and August 1, 2007 were enrolled. Data were collected from electronic medical records according to the 1996 & 2002 CDC definitions of NP. RESULTS: According to the 1996 CDC definitions of NP, there were a total of 116 NP cases and incidence rate was 11.6 per 1,000 patient-days; when analyzed with the 2002 CDC definitions of NP, 75 cases met the criteria and the incidence rate was 7.5 per 1,000 patient-days. Kappa value measuring agreement between the two definitions was 0.67 (95% confidence interval 0.601-0.706). When 1996 CDC definitions were compared with 2002 CDC definitions, sensitivity, specificity, positive predictive value, and negative predictive value were 93.3, 88.5, 60.3, and 98.6%, respectively. CONCLUSION: Even though the aforementioned NP criteria had been applied to the same study population, the number of patients that met the definitions changed depending on which criteria had been used. Therefore, it is necessary to consider the differences when making a comparison.
