1.Cardiovascular Diseases in Korea.
Korean Circulation Journal 1976;6(2):1-15
Statistical observation was made on the 1949 patients with cardiovascular diseases who had been treated in Dept. of Internal Medicine, Seoul national University Hospital during the period of four years, from jan. 1972 to Dec. 1975. 1) The patients wth cardiovascular diseases accounted for 20.2% out of total 9,638 medical inpatients. The incidence for the consecutive years was not apparently variable. 2) The diseases occured most frequently in the sixth decades and the incidence decreased in the order of fifth and seventh decades. 3) The disease was more prevalent in male than female with ratio of 1.3 of 1. 4) The hypertension was the most common disease among cardiovascular diseases, accounting for 67.5% of patients with cardiovascular diseases and 13.6% of total medical inpatients. The disease occurred most frequently in the sixth decades and the incidence decreased in the order of fifth and seventh decades with male preponderance. 81.8% of patients with hypertension was essential hypertension and 18.2% was secondary hypertension. Secondary hypertension was caused by parenchylmal renal diseases in most patients and there were only several patients with renovascular and endocrine hypertension. 40.2% of patients with essential hypertension had no complications, 38.6% had cerebral vascular accidents, 12.1% had uremia and 9.1% had congestive heart failure. The patients with malignant hypertension was 9.6% of total patients with hypertension. 5) Rheumatic heart disease was 14% of patients with cardiovascular diseases, being second in incidence. It was more prevalent in female than male with ratio of 1 male to 1.3 female and affected the mitral valve in most of the cases, whereas involvement of aortic valve was rare. 6) The coronary heart disease was 5.3% of patients with cardiovascular diseases, being third in incidence. It occured most frequently in seventh and sixth decades and affected male two times more frquently than female. 7) The congenital heart disease was 2.9% of patients with cardiovascular diseases, of which atrial septal defect was highest in incidence. 8) The cor-pulmonale was 1.4%, pericarditis 1.4%, endocarditis 0.9%, postpartum heart disease 1.2%, myxedematous heart disease 0.2%, arrhythmia 2.1%, peripheral vascular disease 1.1% and miscellaneous 0.6% of patients with cardiovascular diseases. 9) Postpartum heart failure and endocarditis was remarkably decreased in incidence recently and there were one patients with beriberi heart disease and one patient with syphilitic heart disease during those years of this study.

One of the commonest and most serious problems of the injured hand is flexion contractures of the fingers. Such deformities not only functionally impair the digit, but also reduce or restrict the functional capability of the entire hand. We reviewed 150 digits of 73 patients with flexion contractures of the fingers which had been treated at National Medical Center from Jan. 1976 to Dec. 1985. The results were as follows: 1. The duration of flexion contractures which were scattered from 4 months to 17 years and average duration of contracture was 20.6 months. 2. The methods of treatment were Z-plasty, adhesiolysis, capsulotomy, excision of both collateral ligaments, stripping of extensor mechanism and volar plate and release of flexor tendon sheath according to injury mechanism and duration of contracture. 3. The postoperative results showed up 32 (21.3%) excellent, 78 (52%) good, 24 (16%) fair and 16 (10.7%) poor. 4. The postoperative results of burned injury which showed up-8 excellent, 11 good out of 20 cases they are supposed to have satisfactory results. 5. Crushing injury which had intraarticular fracture or comminution show up unsatisfactory results. 6. It seems obvious that the early active motion of interphalangeal joint is important to improve joint function. 7. The arc of motion was retained in a more functional position postoperatively than preoperatively.

PURPOSE: We measured pulmonary epithelial permeability by Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. MATERIALS AND METHODS: We performed ' Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asym-ptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). Tc-DTPA clearance half-time (T1/2) was calculated, then compared with the result of chest radiography and pulmonary function test. RESULTS: Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with micraangiopathy were significantly older (p<0.05). The T1/2of normal subjects and asyrnptomatic smokers were significantly different (65.2+23.7min vs 39.6+9.8min, p<0.05). For diabetic patients with microangiopathy, the T, was 90 5+46.5min and significantly delayed when compared with those of normals and asymptomatic smokers (p<0.05). However, the T1/2of diabetic patients without microangiopathy, 70.0+12.7 min, was not significantly different from those of normals or asyrnptomatic smokers (p>0.05). No significant correlation was found between the T1/2and spirometric parameters including DLcc>, FVC, FEV>, FEV(/FVC (%) and FEF)5-75g in all subjects, and between the T1/2 and duration of diabetes in diabetic patients. CONCLUSION: Eventhough the influence of age cant be excluded, delayed Tc-DTPA clearance half-time (T1/2)in diabetic patients with microangiopathy indicates decreased pulmonary cspillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy.

PURPOSE: To implement evidence-based nursing, it is important to know where and how to find the best available evidence. This study was conducted to identify the results of a search from Ovid MEDLINE and to compare the results from Ovid MEDLINE with those from PubMed MEDLINE. METHODS: Four different approaches via Ovid MEDLINE were used to search for guidelines on preventing catheter-associated urinary tract infections. Outcomes of this study were the number of records and relevant literature, and the sensitivity and precision of the search methods via Ovid MEDLINE. RESULTS: The number of retrieved items ranged 23 to 6,005 and that of relevant studies, 5 to 8 of 8. Simple searches resulted in the highest sensitivity of 100.0%. When using MeSH terms and limits feature, the precision was highest (21.7%) among four approaches for literature searches. Simple searches in Ovid had higher sensitivity and lower precision than those in PubMed. CONCLUSION: Simple searches in Ovid may be inefficient for busy clinicians compared to PubMed. However, to ensure a comprehensive and systematic literature search, using Ovid MEDLINE in addition to PubMed is recommended.

Congenital pericardial defect is relatively rare and two different types, partial and complete, of different clinical significance have been recognized. Most reported defects are complete type and left-sided lesion. Most patients are asymptomatic or complain of vague chest pain. Partial pericardial defect can be potentially fatal due to cardiac herniation and strangulation or coronary insufficiency. Plain chest reontgenography shows abnormal prominence along the cardiac border. 2-D echocardiography demonstrates a drop-off of pericardial echo and protruding cardiac chamber through the defect. Because of the potential fatality, surgical repair is recommended for the partial pericardial defect. We report a case of congenital partial left pericardial defect, which was diagnosed by plain chest reontgenography and 2-D echocardiography, with related literatures.

PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

BACKGROUND: The risk of bleeding during extracorporeal membrane oxygenation (ECMO) is a potential deterrent in performing tracheostomy at many centers. To evaluate the safety of surgical tracheostomy (ST) in critically ill patients supported by ECMO, we reviewed the clinical correlation between preoperative coagulation status and bleeding complication-related ST during ECMO. METHODS: From April 1, 2012 to March 31, 2016, ST was performed on 38 patients supported by ECMO. We retrospectively reviewed and analyzed the medical records including complications related to ST. RESULTS: Heparin was administered to 23 patients (60.5%) for anticoagulation during ECMO, but 15 patients (39.5%) underwent ECMO without anticoagulation. Of the 23 patients administered anticoagulation therapy, heparin infusion was briefly paused in 13 prior to ST. The median platelet count, international normalized ratio, and activated partial thromboplastin time before ST were 126 ×109/L (range, 46 to 434 ×109/L), 1.2 (range, 1 to 2.3) and 62 seconds (27 to 114.2 seconds), respectively. No peri-procedural clotting complications related to ECMO were observed. Two patients (5.3%) suffering from ST-related major bleeding required surgical hemostasis. Minor bleeding after ST occurred in two cases (5.3%). No significant difference was found according to anticoagulation management (P = 0.723). No fatality was attributable to ST. CONCLUSIONS: The complication rates of ST in the patients supported by ECMO were low. Therefore, ST performed by an experienced operator, and with careful optimization of coagulation status, is a relatively safe procedure; the use of ST with ECMO should thus not be dismissed on account of the potential for bleeding caused by the administration of anticoagulants.

For the purpose of elucidating relation between red cell electrolyte concentrations and serum digoxin level, measurement of red cell electrolyte concentrations and seum digoxin level by radioimmunoassay were done in 46 normal controls and 63 patients of CHF including 8 patients with digitalis intoxication. The results obtained were as follows: 1. Red cell sodium concentration and ratio of red cell sodium to red cell potassium concentration in normal males were significantly higher than those of females, and red cell potassium concentration in normal males was significantly lower than that of normal females. 2. Red cell potassium concentration in patients of CHF was significantly higher than that of normal controls, but there was no difference in the red cell sodium concentration between the groups. 3. There was no relation between red cell electrolyte concentrations and serum digoxin level, and red cell electrolyte concentration did not exactly estimate serum digoxin level. 4. Red cell electrolyte concentrations in the patient of CHF were valuable in detecting digitalis toxicity.
