Noncompaction of the ventricular myocardium is a rare congenital cardiomyopathy caused by arrest of normal endomyocardialembryogenesis. Isolated right ventricular noncompaction (IRNC) is an even rarer form of this disease. We report herein on a 68year-old male diagnosed with IRNC who presented with right-sided heart failure, without involvement of the left ventricle. Diagnosis was achieved with the aid of echocardiography and ventriculography. Medical treatment including prescription of diuretics,a calcium channel blocker, and digitalis, improved both the symptoms and right ventricular function.

Erythromycin 및 Rifamycin 두 종의 항생물질 발효 부산물의 농업적 이용에 대한 검토를 위하여 발효 부산물 자체의 이화학적 성질의 조사와 함께 경기도 벽제 소재 일반 농가의 논과 밭토양을 이용하여 수도 및 토마토를 표식작물로 하여 두 종 시험물질은 시용효과를 조사한 결과는 다음과 같다. 1) 항생물질 발효균제 두 종은 모두 중성물짙(pH 6.8∼7.4)로서 다량의 유기물(21.6∼24.2%), 인산 (2900∼4600 ppm) 및 치환성 염류(55.4∼138.3meq/100g)를 함유하였다. 2) 두 종의 항생물질 부산물은 일반토양 보다 높은 등전점(pH 7.0∼8.0)을 가짐과 동시에 양전하의 발달이 급격하여 음 ion의 흡착용량이 큰 것으로 나타났다. 3) 수도에 대한 두 종 항생물질 부산물의 시용효과는 삼요소 단용구 및 기타 유기질 비료의 시용효과와 대응하였으며 반당 40㎏ 시용에서 최대의 정조 수량을 나타내었다. 4) 토마토에 대한 두 종 항생물질 부산물의 시용효과도 수도에 대한 결과와 유사한 경향을 보여 평균적으로 기타 비료 시용효과와 대등하였다. 5) 생육상황 중 수도는 식물체 초장, 건물중 및 유효 분얼 주당 수수, 그리고 토마토에 있어서는 묘목수장과 생체중이 각기 수량과 유사한 결과를 나타내어 이들이 수량증가에 관계가 있음을 나타내었다. In order to evaluate the applicability of two kinds of antibiotic fermentation residues on rice and tomato growth, yield, yield components, and some indicators for plant growing status were checked including analysis of physico-chemical properties of these two antibiotic fermentation residues. The results obtained are as follows: 1) These two antibiotic fermentation residues contain high organic matter (21.6∼24.2%), phosphorus (2900∼4600 ppm) and exchangeable cations (55.4∼138.3 meq/100 g,), showing their pH values of 7.0∼8.0 range. 2) Both have developed net positive charge rather high and stiffly that exhibits high negative ion adsorption capacities, accordingly showing higher zero point of charges(pH 7.0∼8.0) than those of common soils. 3) The effect of the two kinds of antibiotic fermentation residues on rice growth was more or less the same comparable to the effect of the other fertilizers applied, showing the maximum yield at the application rate of 40 ㎏/10 a. 4) The effect of these antibiotic fermentation residues on tomato growth was also similar to effects on rice plant showing the yield increment upon fertilizer application including two antibiotic fermentation residues but no significant differences among fertilizers. 5) According to the plant growing status, plant height, dry matter, number of effective tillers and grain number per panicle of rice and plant height and fresh weight of plant of tomato showed similar trend with yield of both plants.

To evaluate geriatric anesthetic experience, 1,441 cases of patients aged over 60 years, out of 29,692 surgical cases admitted to St. Mary's Hospital from January 1971 to December 1980 were analyzed according to age, sex, surgery, preoperative condition, technique of anesthesia, duration of anesthesia, anesthetics, and mortality. The results were as follows: 1) The percentage of geriatric cases were 4.9% in average which ranged between 3.9% and 6.0% and showed steady numbers in this period. The distribution of the number of patient according to the age were 1,150 cases (79.8%) in the group of 60-69 years, 262 cases (18.2%) in 70-79 years, 29 cases (2.0%) over 80 years. 2) There were 833 male (57.8%) and 608 female (42.2%) cases. 3) 833 cases (57.8%) were in general surgery; the most prevalent diagnosis were empyema of gallbladder and cholelithiasis which amounted to 196 cases (13.6%0 4) The rates of elective to emergency surgery were 75.4% (1086 cases)to 24.6% (355 cases). 5) Premedicants were mainly atropine with sedatives (785 cases, 61.2%) and atropine with analgesics (220 cases, 17.1%). 6) Preoperative hemoglobin level ranged between 10.1 and 12.0 gm/dl in 40.1% of the patients. 7) The techniques of anesthesia were (1.234 cases, 85.6%) general anesthesia, (75 cases, 5.2%) intravenous anesthesia and spinal anesthesia (60 cases, 4.2%). 8) The duration of anesthesia (500 cases, 34.7%) were 1-2 hours in average. 9) The inhalation anesthetics were Halothane (1,110 cases, 90.0%), Methoxyflurane (112 cases, 9.1%), N_2O (6 cases, 0.5%), and Ether (6 cases, 0.5%). 10) The preoperative chest X-ray and clinical signs showed that 963 cases (64.3%) were normal, 159 cases (10.6%) had emphysems, 152 cases (10.1%) had pulmonary tuberculosis and 41 cases (2.7%) had bronchitis. 11) The preoperative EKG and clinical symptom revealed that 952 cases (62.1%) were normal in cardiovascular aspect, 232 cases (15.1%) showed hypertension, 124 cases (8.1%) had arrhythmia, and 79 cases (5.2%) had myocardial ischemia. 12) During the surgical procedure cardiac arrest were experienced in 5 cases (0.3%) and sudden hypotensivee pisods in 18 cases, which successfully resucitated. There were no operative mortalities within 48 hours. In summary, the patients over the 60 to 80 age group had a poor surgical risk but they were able to withstand this risk when properly managed with modern anesthesia.

목적: 골다공증성 압박 골절 후 새롭게 나타나는 압박 골절을 조사하여 위험인자를 알아보고자 하였다. 대상 및 방법: 다기관 후향적 연구로, 세 개의 병원에서 골다공증성 급성 압박 골절에 대한 치료를 시행하고, 1년째 척추 영상을 얻을 수 있었던 135명을 조사하였다. 1년째 새롭게 발생된 척추 골절의 유무를 조사하여 골절이 발생한 군과 발생하지 않은 군으로 나누어 각각 군별로 대상 환자들의 연령, 성별, 동반 질환 여부, 골밀도, 급성 압박 골절의 부위, 기존 척추 골절의 유무, 골다공증 약물복용률, 치료방법의 차이에 대해서 조사하였다. 결과: 1년째 새로운 척추 골절은 총 25명(18.5%)에서 발견되었으며, 새로운 척추골절이 발생한 군과 그렇지 않은 군 간의 비교에서 연령, 성별, 동반 질환 여부, 급성 압박 골절 부위, 기존 압박 골절의 빈도에는 유의한 차이는 없었다. 새로운 척추 골절은 성형술을 시행한 경우(p=0.003, odds ratio=4.71)와 대퇴 경부의 T-score가 -2.5 이하인 경우에 유의하게 높은 빈도를 보였다(p=0.013, odds ratio=3.47). 결론: 골다공증성 압박 골절 후에 발생된 새로운 척추 골절의 위험 인자는 척추 성형술이나 풍선 성형술, 대퇴 경부 T-score -2.5 이하였다. Purpose: To evaluate the risk factors for subsequent vertebral fracture following acute osteoporotic vertebral compression fracture. Materials and Methods: This was a multicenter retrospective study. We recruited 135 patients treated for acute osteoporotic compression fracture with available spine image taken at the 1-year follow-up mark in 3 different hospitals. The patients were divided into 2 groups in accordance with the occurrence of subsequent vertebral fracture. Variables including age, sex, bone mineral density, medical comorbidity, acute fracture level, presence of prior vertebral fracture, osteoporosis medication, and treatment method were analyzed and compared between the 2 groups. Results: The new subsequent vertebral fractures were detected in 25 patients (18.5%). There were no significant differences between the 2 groups with respect to age, sex, medical comorbidity, presence of prior vertebral fracture, and acute fracture level, as shown by univariate analysis. However, in the group with subsequent vertebral fracture, more patients were treated by vertebroplasty or kyphoplasty and had a femur neck T-score of ≤-2.5, as well as poor compliance of osteoporosis medication with significant difference (p<0.05). According to the multivariate analysis, subsequent vertebral fractures were significantly influenced by vertebroplasty or kyphoplasty (p=0.003, odds ratio=4.71) and femur neck T-score of ≤-2.5 (p=0.013, odds ratio=3.47). Conclusion: Subsequent vertebral fractures were found in 19% at the 1-year mark after the treatment of acute osteoporotic compression fracture. The two risk factors for subsequent vertebral fractures were vertebroplasty or kyphoplasty and femur neck T-score of ≤-2.5.
