Morphologically, kyphosis is devided into two groups, pure kyphosis and kyphoscoliosis, according to whether or not scoiiosis is combined. Or kyphosis can be devided into round kyphosis or angular kyphosis. The examples of round kyphosis are Scheuermanns kyphosis or ankylosing spondylitis. Acute angular kyphosis are of congenital kyphosis or old healed tuberculosis. The purpose of surgical correction of fixed kyphosis is to correct deformity as well as to prevent or to recover from paraplegia. The operation also improve respiratory and digestive function by diminishing compression of abdomen. However, the correction of this deformity is more dangerous in eliciting paraplegia than any other spinal deformity. In considering surgical correction of kyphosis we have to decide which approach is the best for that particular patient at that particular time. Usually majority of patient need combined anterior and posterior approach. The extent of fusion depends upon the flexibility of the kyphosis. Anterior fusion should encompass at least the rigid and inflexible portion of the kyphosis as determined by the hyperextension x-ray of the spine. Posterior fusion should encompass the full extent of the kyphosis. The purpose of this study is to report our results for surgical correction and to find the operative procedure which shows the best result. We hereby report surgically corrected 14 cases of fixed kyphosis who were hospitalized here from April 1988 to February 1995.

The cardiac performance is regulated by the intergration of preload, afterload, contractility (inotropism), heart rate and synergy of ventricular contraction, which are the major determinants that govern the stroke volume and cardiac output. Valvular heart disease may be considered to impose two different types of stress on the cardiac chamber proximal to the lesion. There are either pressure overload(increased after load) or volume overload(increased preload). The compensatory mechanism of the pressure overload and volume overload offer to hypertrophy and dilatation of the chamber. Hypertrophy, increased muscle mass, calls upon the development of greater systolic force. Dilatation, overfilled chamber volume enables increased strength and extent of shortening by Frank Starling's mechanism. In these view, we shall discuss the hemodynamic parameters; cardiac output, stroke volume, ventricular end-diastolic pressure, and the rate of ventricular pressure rise(peak dp/dt), mitral valve gradient and pulmonary circulation. The authors had an opportunity to study 40 cases of mitral valvular heart disease which were accepted during the left ventricular angiography at the cardiac catheterization room and at the fields of operative findings during the period Jan. 1977, throught Sept. 1980, at the Department of Internal Medicine, National Medical Center. The following conclusions were drawn: 1) Cardiac index was 2.65 L/min/m2in average, among 18 cases with mitral stenosis and 2.54 L/min/m2 in average, among 15 cases with mitral valve area of less than 1.0 cm2. Cardiac index was 2.58 L/min/m2in average, among 19 cases with mitral stenoinsufficiency and 3.43 L/min/m2 in average, among 3 cases with pure mitral insufficiency. 2) The mean right ventricular end-diastolic pressure elevated more than 0-8 mmHg were found in 12 cases with mitral stenosis out of 18 cases and mean miral valve area was 0.8m2. The mean left ventricular end-diastolic pressure was also elevated more than 0-12 mmHg in 6 cases out of 12 cases with mitral stenosis in addition to right ventricular failure. These 12 cases of mitral stenosis had cardiac function more than class III clinically. 3) 15 cases with mitral valve area, less than 1.0cm2 demonstrated left ventricular diastolic filling pressure gradient (MVG) of 17.3mmHg in average, the pulmonary vascular resistance of 568 dyndsecd cm(-5) in average, and the right ventricular peak systolic pressure of 72mmHg in average respectively. In all instances, the right ventricular end-diastolic pressure was 11.2mmHg in average and right ventricular peak dp/dt was 571mmHg in average. 4) Among 22 cases with mitral insufficiency, and/or mitral stenoinsufficiency 16 cases showed mean left ventricular end-diastolic pressure elevated more than 0-12mmHg. 10 cases out of these 16 cases disclosed also right ventricular end-diastolic pressure elevated more than 0-8 mmHg. These 16cases of mitral insufficiency and/or mitral stenoinsufficiency had cardiac function more than class III clinically. 5) 16 cases with mitral insufficiency and/or mitral stenoinsufficiency who had mean left ventricular end-diastolic pressure more than 0-12 mmHg showed pulmonary vascular resistance, 358 dyndsecd cm(-5) in average, systemic vascular resistance, 1621 dyne/sec/cm5 in average and left ventricular peak dp/dt, 768-2102mmHg/sec in range. 6) Pulmonary hypertension elevated more than 50mmHg of pulmonary arterial systolic pressure was found in 14 cases out of 18 case with mitral stenosis and in 10 cases out of 22 cases with mitral stenoinsufficiency and/or mitral insufficiency. Pulmonary vascular resistance, however, was markedly variable.

The frequency of medical care utilization per household in a one month period was 4.6 in the poor area and 4.3 in the control area. The average number of days of utilization was 12.9 in the poor area and 12.5 in the control area. The averge monthly income of a househlod in the poor area was 848,600 Won compared to the control area's 1,752,300 Won. The average monthly consumption expenditure of a household in the poor area was 568,800 Won and that in the control area 1,238,400 Won. The average medical care monthly expenditure per household was 34,500 Won in the poor area and 58,400 Won in the control area. The proportion of the medical care expenditure to monthly income and to monthly consumption expenditure was 4.1% and 6.1% respectively in the poor area, and 3.3% and 4.7%, respectively in the control area. The premium of medical insurance was 1.5% in both areas. The proportion of cost for drug was 57.4%, for medical appliance was 1.2%, and for medical treatment was 41.1% in the poor area and in the control area 52.4%, 1.9%, 45.7%, respectively. The highest proportion of medical care expenditures in the poor area was herb clinic utilization (36.9%). while hospital and clinic (37.8%) was the highest proportion in the control area.

Hypertensive encephalopathy is an acute clinical syndrome that shows central nerve dysfunction with sudden and marked elevation in blood pressure. But its pathophysiologic mechanisms, clinical courses and prognosis are still not clear. In order to study clinical manifestations and response to treatment in patients with hypertensive encephalopathy, we reviewed 45 patients with hypertensive encephalopathy who were admitted in Dept. of Internal Medicine, National Medical Center, from January 1975 to December 1984. The following results were obtained: 1) The ratio of male to female was 1.1:1. The peak age of incidence was in the 6th and 7th decade with mean age of 57.5 years. 2) Among 45 patients, only 29 had known history of hypertension and the average duration of hypertension was 8.1+/-3.6 years. 3) The most common sympotm was severe headache (68.9%). And altered consciousness, nausea and/or vomiting, focal neurologic signs and visual disturbance were also common symptoms in decreasing order of frequency. 4) Funduscopic examination showed hypertensive retinopathy in 20 of 24 (91.7%) patients and lumbar puncture revealed increased CSF pressure in 12 of 20 (60%) patients. 5) In most patients, the mean interval to symptomatic improvement was 2.1 days after administration of anti hypertensive agents, but in 6 patients with initial mean arterial blood pressure above 170mmHg, 4 patients showed delayed response and 2 patients were expired.

Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. The various hypothesis and classification are proposed. Type V in Frieden's classification, which is associated with fetus papyraceus or placental infarcts, occurs as a large cutaneous defect on the trunk and extremities. We experienced the patient had skin defect affecting the lower abdomen symmetrically, with no family history of the any disorders or chromosomal anomalies and associated anomalies. A twin fetus was died in utero. We report a case of aplasia cutis congenita associated with fetus papyraceus with the review of the associated literatures.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.
