An analysis and CT findings in 21 adult patients of spontaneous intracerebral hematoma(SICH) mixed with CSF who were admitted to the Fatima Hospital from December 1986 to May 1989. The following results were obtained; 1) We could differentiated SICH that have inhomogenous density and thought that it is composed of blood, CSF and blood-CSF mixture. 2) Previously reported pathways that intracerebral hematoma rupture into the ventricle are caudate nucleus and thalamus but intracerebral hematoma can be mixed with CSF through the subarachnoid space of Sylvian fissure as an another route. 3) Intracerebral hematoma mixed with CSF was removed easily, safely and enoughly with simple aspiration method as like resoluted hematoma in subacute or chronic phase. 4) The prognosis of patients with SICH mixed with CSF was very good unlike to that of patients with pure intracerebral hematoma and/or ventricular hemorrhage.

Three cases of chronic subdural hematoma superimposed on posttraumatic subdural hygroma are presented, with discussion of the development of the chronic subdural hematoma particularly. In all of these three cases the chronic subdural hematoma had occurred consequently to the posttraumatic subdural hygroma, but these diagnoses were done in variable periods of 20 days to 60 days. Therefore, it is suggested that the posttraumatic subdural hygroma have, at least, some relation to the genesis of the chronic subdural hematoma.

BACKGROUND: Although operative outcome is progressing due to the development of operative techniques and myocardial protection, some patients face an increased morbidity and mortality. Therefore, it has become increasingly important to predict the operative morbidity and mortality. MATERIAL AND METHOD: This retrospective study reports the results of risk factor analysis of morbidity and mortality of 137 consecutive patients who were underwent coronary artery bypass graft surgery (CABG). Preoperative variables were age, sex, preoperative myocardial infarction, operative priority, left ventricular ejection fraction, obesity and triple vessel disease. Postoperative morbidities were arrhythmia, wound infection, cerebral infarction, prolonged postoperative hospitalization, pneumonia, acute renal failure, prolonged use of ventilator and operative death. RESULT: The mean age of total patients was 56.7 years, from 27 to 74. The overall mortality was 6.6% (9 of 137) with the mortality of 3.9% (5 of 128) for elective operation, and 44.4% (4 of 9) for emergent or urgent cases. The morbidity of patients over 65 years was stastistically higher than that of under 65 years. Sex distribution showed no difference in morbidity, however operative mortality rate was slightly higher in women (5/41, 12.19%) than in men (4/96, 4.17%). Morbidity of emergent or urgent operation was 100%, much higher than that of the elective operation. Mortality of the patients whose left ventricular ejection fraction was under 50% was higher than that of those over 50%. CONCLUSION: We concluded that the risk factors of morbidity after CABG were old age above 65 years and emergent or urgent operation, and that risk factors of mortality were low left venticular ejection fraction under 50% and emergent or urgent operation.

BACKGROUND: Hypertension is the most common cause of left ventricular hypertrophy(LVH). Increased left ventricular mass(LVM) carries independent risk for congestive heart failure, coronary artery disease, sudden death, reduction of coronary reserve. The importance of treatment in systemic hypertension for cardiovascular morbidity and mortality has been estabilished. Regression of LVM occurs with a number of antihypertensive drugs. This study was designed to explore the relation between blood pressure control, LVM and left ventricular filling dynamics. METHODS: Twenty five patients (12 men, 13 women) with estabilished hypertension were studied. No patients had a previous history of antihypertensive therapy. We obtained the basal echocardiography at the diagnosis which were disclosed no definite LVH, and the follow-up echocardiography after 6 months antihypertensive therapy with angiotension converting enzyme inhibitor, fosinopril, in patients with untreated essential hypertension. RESULTS: 1) Baseline blood pressure was 150/125mmHg and fell to 104/85mmHg (p<0.001). There was no siginificant reduction in heart rate. LVM were reduced from 153gr/m2 to 129gr/m2. 2) Peak E velocity and Peak A velocity was 82.9cm/sec, 74.9cm/sec and reduced to 67.2cm/sec, 62.3cm/sec, (p<0.001). 3) Time velocity integral dimension E (Ei) and time velocity integral dimension A (Ai) was 13.0cm, 9.0cm and reduced to 8.6cm, 4.5cm respectively. But there was no significant inteval change in peak E/A velocity. Ei/Ai was increased from 1.7 to 2.1 (p<0.01). CONCLUSIONS: These results suggested that antihypertensive therapy with ACE inhibitor for 6 months reduced significantly the left ventricular mass in patients with untreated essential hypertension.

The perforator flaps are based on cutaneous vessels which are originated from a main pedicle and penetrate fascia or muscle to reach the skin. The lateral lower leg is one of the most suitable areas for harvesting perforator flaps because a number of perforator vessels exist. The authors applied peroneal perforator flaps in nine patients. Five flaps were reverse island flaps based on peroneal artery and septocutaneous perforator, and four flaps were free flap based on musculocutaneous perforator only. The recipient site was the posterior ankle in three patients, posterior heel in three patients, lateral malleolus, anterolateral ankle, and foot dorsum in one patient each. The flap size ranged from 5 to 12cm long, from 3 to 5cm wide, and the primary closure of the donor site was possible in most cases. All flaps, except for the flap in two patients in the reverse island flap series, survived completely. The peroneal perforator flap is a very thin, pliable flap with minimal donor site morbidity and is suitable for the reconstruction of small and medium sized superficial skin defects. Also, this flap may be considered as an alternative to radial forearm flap or other perforator flaps.

PURPOSE: The purpose of this study was to evaluate the oncologic outcomes of parosteal osteosarcoma (POS) and to ascertain the fates of patients after local recurrence (LR). MATERIALS AND METHODS: The authors retrospectively reviewed 22 POS patients with an average follow-up of 114 months (range: 36-235 months). Seven of the 22 patients were referred after LR. There were 17 Stage IB and 5 Stage IIB (G2, 2; dedifferentiation, 3). Tumors were located in the femur (11) and in other locations (11). Initial surgical margins were wide in 10, marginal in 5, and intralesional in 7. Correlations between clinico-pathologic variables and LR and clinical courses after LR were evaluated. RESULTS: The 10-year overall survival rate was 85.7%. Three (14%) patients developed distant metastasis and all of them succumbed to the disease. Nine (41%) patients developed LR. Tumor location, resection type, and surgical margin were found to be correlated with LR. At final follow-up, 7 of the 9 patients that experienced local failure achieved no evidence of disease. CONCLUSION: A substantial risk of misdiagnosis exists, especially for POS in other than a femoral location. Recurrent tumor re-excision is possible in most cases; however, patients with an aggressive recurrence pattern deserve special attention.

PURPOSE: The goal of periodontal regenerative therapy is to replace bone, cementum, and periodontal ligament on a previously diseased root surface, which has suffered the loss of these supporting structures. To accomplish the regeneration, a number of surgical procedures have been advocated throughout the years. There seems to be a potential for some spontaneous periodontal tissue regeneration in the bottom of periodontal defect following open flap debridement alone. The aim of this study was to analyse the radiographic bone changes over 2-year after flap operation. MATERIAL AND METHODS: Patients attending the department of periodontics of Kyungpook National University Hospital were studied. Patients had clinical and radiographic evidence of infrabony defect(s). forty two sites of 33 patients aged 26 to 65 (mean age 45.5) were treated by flap operation with or without osseous surgery. Baseline and over 2-year follow-up radiographs were collected and evaluated for this study. Radiographic assessment includes a bone fill, bone crest change, defect resolution, and % of defect resolution. Pre- and post-treatment differences between variables (maxilla and mandible, gender, defect depth, defect angle) using the paired t-test were examined. RESULT: We observed 0.74 mm of bone fill, 0.66 mm of crestal resorption, 1.40 mm of defect resolution, and 27% of percentage of defect resolution. Mandible, women, deeper initial defect depth, narrower initial defect angle showed greater bone fill, defect resolution, and % of defect resolution. CONCLUSION: The results of this study suggest that the use of flap operation did enhance the outcome in terms of radiographically detectable bone fill. Both treatment resulted in some loss of crestal bone height.

OBJECTIVES: To integrate the results of studies which assess an association between blood lead and blood pressure. METHODS: We surveyed the existing literature using a MEDLINE search with blood lead and blood pressure as key words, including reports published from January 1980 to December 2000. The criteria for quality evaluation were as follows: 1) the study subjects must have been workers exposed to lead, and 2) both blood pressure and blood lead must have been measured and presented with sufficient details so as to estimate or calculate the size of the association as a continuous variable. Among the 129 articles retrieved, 13 studies were selected for quantitative meta-analysis. Before the integration of each regression coefficient for the association between blood pressure and blood lead, a homogeneity test was conducted. RESULTS: As the homogeneity of studies was rejected in a fixed effect model, we used the results in a random effect model. Our quantitative meta-analysis yielded weighted regression coefficients of blood lead associated with systolic blood pressure and diastolic blood pressure results of 0.0047 (95% confidence interval [CI]: -0.0061, 0.0155) and 0.0004 (95% CI: -0.0031, 0.0039), respectively. CONCLUSIONS: The published evidence suggested that there may be a weak positive association between blood lead and blood pressure, but the association is not significant.

BACKGROUND: This study was designed to compare the usual self-checked blood pressure measuring methods by hypertensive patients with standardized methods. METHODS: From May to August 2002, we surveyed 137 hypertensive patients who performed self blood pressure measurements with a self-administered questionnaire. We defined 14 standard methods from the six most frequently recommended guidelines. We asked patients how often they calibrated their sphygmomanometer, and how they learned to measure blood pressure. Also, their upper arm circumferences were measured. RESULTS: The percentage of correct preparations for BP measurement was over 80%, but that of correct technique was low. For example, 'reading from the arm with higher BP by more than 10 mmHg' (4.4%), 'placing midline of the bladder over the arterial pulsation' (21.5%), and 'waiting 2 or more minutes between readings' (21.9%). Only 11.2% of the patients have ever had calibrated their sphygmomanometers. In 20.2% of hypertensive subjects, upper arm circumferences were greater than 30 cm which made blood pressure measurement with a 24 cm-sized bladder incorrect. CONCLUSION: As shown in previous studies, the methods of blood pressure measurement were incorrect in many aspects. Therefore, systematically educating hypertensive patients to measure blood pressure by correct methods and recommending to use a proper-sized cuff are essential.
