The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.

Myocardial bridge is not a rare congenital malformation of the coronary artery which takes an intramural course. Most of the lesions are found in proximal half of the left anterior descending coronary artery, but one which occurs in the left circumflex artery is extremely rare. During systole, the intramural coronary artery is compressed by contraction of over bridging ventricular muscle, therefore blood flow distal to the lesion in impaired and angina pectoris or acute myocardial infarction may occur. We experienced a 54-year-old man who complained of severe precordial pain during exercise and at rest for several months, and was diagnosed as myocardial bridging in the left circumflex coronary artery by coronary arteriography. Thus we report this case with literature review.

A new angiotensin converting enzyme inhibitor, enalapril, was administered in 20 hypertensive patients (7 mild, 6 moderate and 7 severe hypertensives) for 8 weeks or longer in order to see the blood pressure lowering effects. Additionally the left ventricular mass index was measured by 2-D guided M-mode echocardiography before and after enalapril therapy, and subjective symptoms and laboratory findings were also followed. The results were as follows: 1) After 8 weeks of enalapril treatment (the doses form 10 mg to 20mg once a day) blood pressure were lowered markedly in 10, moderately in 4, mildly in 4 cases, but the blood pressures were not lowered in 2 cases with severe hypertension. The means of the blood pressures of the group were lowered form 182.1+/-19.2 to 148.0+/-26.0mmHg in systolic and from 111.9+/-14.7 to 95.1+/-17.1mmHg in diastolic after 8 weeks of treatment (p<0.001). 2) Heart rates were not changed significantly with enalapril. 3) The symptoms of insomnia and headache were reported to be improved after enalapril in 13 cases. 4) No discernable changes in CBC and serum level of creatinine were observed. But the random urine protein was decreased in 6 cases with proteinuria in routine urinalysis. The serum lipid profile was not significantly changed, but in the 2 cases in which the ratio of total to HDL-cholesterol was above 5.0, the ratio fell to below 5.0. 5) There was no significant EKG change after enalapril. 6) In 9 cases out of 13 cases with the left ventricular mass index (LVMI) above 125g/m2 BSA, LVMI was followed by echocardiography after enalapril. LVMI was significantly decreased in 8 of 9 cases and mean values after enalapril was decreased from 183.1+/-88.0g/m2 BSA to 150.8+/-61.3g/m2 BSA (p<0.0025). 7) Side effects after enalapril administration were transient dizziness in 4 cases and ageusia in 2 cases. Above results suggest that the enalapril could be an initial choice in the treatment of essential hypertension as a single oral agent in once a day regimen resulting in good antihypertensive effects, improvement of subjective symptoms, regreassion of the left ventricular hypertrophy and few side effects.

For the evaluation of the left ventricular diastolic function in mild to moderate hypertensive patients without left ventricular hypertrophy, 15 hypertensive patients (group A) and 15 normotensive subjects (group B) were examined by 2-D guided M-mode echocardiography. Various systolic and diastolic indices were derived from computer-assissted analysis of differential curves of left ventricular dimension and posterior wall thickness. The systolic and diastolic function indices of each of the two groups were compared. The results were as follows : 1) There were no significant differences in ejection fraction, left ventricular peak ejection rate and posterior wall thickening rate between two groups. 2) There were no significant differences in % ventricular A wave, left ventricular peak filling rate and posterior wall peak relaxation rate between two groups. 3) One third filling rate was 2.07+/-0.41 EDD/sec in group A and which was significantly lower than 3.29+/-0.88 EDD/sec of group B. Above result suggests that computer-assisted analysis of differential curves of left ventricular dimension and posterior wall thickness could be helpful in the early detection of diastolic dysfunction, and that left ventricular diastolic dysfunction in its early filling period may develop in the mild to moderate hypertensive patients even before left ventricular hypertrophy develops.

Catopril, an angiotensin converting enzyme inhibitor, was administrated in 30 hypertensive patients(mild 8, moderate 12, severe 10 cases)for 12 weeks or longer in order to observe the hypertensive effects. Changes in quality of life, side effects, electrocardiogram and left ventricular mass index(LVMI) by 2D-guided M-mode echocardiography were also evaluated before and after captopril. 1) After 12 weeks treatment with 25 to 150mg of captopril alone, blood pressures were lowered markedly in 16(53%), moderatly in 5(17%) and midly in 2(7%), while the addition of 25mg hydrochlorthiazide to captopril in the patients who showed no satisfactory responses the blood pressure were lowered markly in 21(70), moderately in 6(20%) and mildly 3(10%) out of 30 patients studied. The average of blood pressure of the 30 subjects were systolic 180.7+/-20.7mmHg(M+/-SD) and diastolic 113.2+/-12.5 before treatment, which were lowered to 148+/-15.8 and 92.5+/-8.0mmHg respectively after 12 weeks(P<0.005). 2) Heart rates were not changed with captopril and/or hydrochlorothiazide. 3) Quality of life improved markedly in 5(17%) and slightly in 12(40%) out of 30 subjects. 4) Complete blood cell count, urinalysis and serum enzymes followed revealed no significant changes. 5) By electrocardiographic follow-up studies 1 out of 13 subjects with LVH, 1 out of 4 LAH, 1 out of 2 ST-T changes were revealed to improved to normal. 6) In 25 out of 30 cases left ventricular mass indices(LVMI) were above 125g/m2 before treatment, among which 15 cases were followed with satisfactoriness good quality of the echocardiographic recorings and the LVMI was reduced from 169.6+/-40.7 to 141.7+/-40.9g/m2(P<0.01). 7) Undesirable side effects were dry cough 3, skin rash 2, dysgeusia 1 and renal dysfunction 1. 8) Considering the blood pressure lowering effects, life quality changed and side effects together the captopril was considered very useful in 8(27%) and useful in 16(53%) out of 30 subjects. Above results suggest that captopril can be prescribed as an effective initial single agent or with in combinations with thiazide for the treatment of hypertensive of various severities with acceptably low side effects.

A 15 year-old boy who was supposed to have had rheumatic myocarditis manifested acute heart failure and transient left ventricular hypertrophy in the early phases of the disease process. Serial echocardiographic examination was very helpful to follow the clinical course and observe the anatomic and functional changes of the heart in conjunction with the clinical status.

PURPOSE: Antenatal steroid(ANS) therapy in premature infants is an effective therapeutic strategy in reducing the incidence of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and patent ductus arteriosus. For premature infants to gain improved survival, adequate weight loss during early postnatal days and maintenance of electrolyte balance is important, however, it is uncertain that ANS affect them. We hypothesized that ANS augment fluid and electrolyte balance and dinical outcome of very low birth weight(VLBW) who had received restricted fluid regimen. METHODS: Mechanically ventilated VLBW infants who survived over 30 days were selected. We reviewed medical records to compare weight loss, urine output, electrolyte concentration, blood pressure during five days of life and clinical outcome between premature infants who received ANS(n=15) and who were not(n=58). RESULTS: Gestational age, birth weight were similar between two groups. Volume of administered fluid, urine output, and initial weight loss during first five days of life were similar, however, weight loss on postnatal day five were lower in study group than control group(p=.039). Blood pressure, serum sodium concentration, serum potassium concentration, and urine specific gravity were similar between two groups. Incidence of respiratory distress syndrome was lower in study group(20%) than control group(48%)(p=.041), however, incidence of sepsis were greater in study group(33%) than control group(7%)(p=.029). CONDUSION: ANS did not affect fluid and electrolyte balance of very low birth weight(VLBW) infants who had received restricted fluid regimen. ANS decreased the incidence of respiratory distress syndrome in this population, however, increased the incidence of sepsis.
