The effects of aminophylline on renal function in 10 premature infants with idiopathic apnea are evaluated. The percent increases in creatinine clearance (128 +/- 339%, mean +/- SD) and sodium clearance (196 +/- 304%, mean +/- SD) are variable while the percent increase in fractional sodium excretion (69 +/- 109%, mean +/- SD) is significant. This effect is postulated to be at the proximal tubule and may be modified by the effects of postnatal age and infusion of albumin. Gestational age, birth weight, heart disease, water and sodium intake and ventilatory support did not appear to influence the results. Hyponatremia is a potential consequence of theophylline therapy for apnea.

The predictive value of 15 pre- and peroperative parameters upon survival after portacaval shunt was analyzed in a retrospective investigation of 134 elective operations. A multiple linear regression model was used. Survival was measured at three different points of time: one month, one year and five years after the operation. Survival at one month was influenced by the parameters bilirubin/s and ascites only. Survival at one year was influenced by albumin/s, sex, bilirubin/s, BSP, heart disease history and ascites Survival at five years was influenced by albumin/s, alkaline phosphatase/s, history of alcohol abuse, and globulin/s. These findings indicate that prediction of survival after portacaval shunt is an intricate process and that considerable improvement of the child criteria is possible.

The cardiac cavities and large vessels were studied by radioisotope angiocardiography with 99mTc-labelled albumin, using a gamma-camera linked to Med-II, with subsequent digital scanning and analysis by coloured video unit (VDP2) of the areas of iso-activity. The results are illustrated of 8 cases selected from the aggregate case histories of 78 patients (1 normal, 4 congenital heart disease, 2 rheumatic, 1 cor pulmonale chronicum). The direct observation of the course of the bolus and the activity/time curves in areas of interest in the cardiac cavities and the lungs, together with the representation of the areas of iso-activity, were useful for diagnosis and physiopathological evaluation of the heart conditions in the patients.

Decreased serum albumin levels are commonly observed in patients with carcinoid tumor, who also show several characteristic clinical and biochemical abnormalities. A large comparative study on a group of 96 carcinoid patients was performed with the purpose of identifying some of the mechanisms leading to hypoalbuminemia in patients with this form of cancer, and thereby to shed light on the cause of hypoalbuminemia of cancer in general. Serum albumin values were compared with a number of clinical parameters (including extent of liver metastases, severity of diarrhea, degree of right heart failure, and extent of gastrointestinal surgery) and of laboratory data (prothrombin time, BSP retention, serum transferrin concentration, hematocrit value, and daily urine excretion of 5-hydroxy-indoleacetic acid). In several patients the gastrointestinal protein loss was assessed by the 51Cr-albumin technique, whereas albumin renewal and distribution were evaluated by the use of 125I-albumin. The data obtained showed that the main factors in determining decreased serum albumin levels in patients with carcinoids are both reduced synthesis and increased loss of the protein. The hepatic synthetic defect appears to be related to a progressive decrease in the number of functioning liver cells; the origin of the gastrointestinal protein loss may be related to the obvious tumor involvement of the gut wall, as well as to the pharmacologically-induced diarrhea. Right heart failure occurring as a result of the carcinoid heart disease may be an additional cause for gastrointestinal protein loss in patients with carcinoid tumor.

The nutritional status of nine patients with end-stage heart disease who were supported by a left ventricular assist device (LVAD) for more than 30 days while awaiting cardiac transplantation was evaluated. Nutritional status was indicated by the following scale: 0-2, adequate nourishment; 3-5, moderate malnourishment; greater than 5, severe malnourishment. This scale was based on serial assessments of albumin, transferrin, total lymphocyte count, percentage of ideal body weight, midarm circumference, triceps skinfold, and arm muscle circumference. Each variable was compared with established standards before implantation and before transplantation times and assessed 1 point if less than the normal value and 0 points if within the normal range. At the time of LVAD implantation, 5 patients had a score of 0-2, 3 patients had a score of 3-5, and 1 patient had a score greater than 5. At the time of cardiac transplantation, 7 patients had a score of 0-2, 2 patients had a score of 3-5, and no patients had a score greater than 5. The patients who were able to meet at least 50% of their daily caloric and protein requirements by oral intake alone were noted. At LVAD implantation, only 2 patients (22%) met this requirement; however, 6 patients (67%) met this requirement at the time of cardiac transplantation. All 9 patients underwent cardiac transplantation, and 8 survived. Thus, it appears that extended LVAD support and maintenance of hemodynamic stability allow patients to regain the desire and ability to achieve adequate nutritional status, which may considerably reduce their perioperative transplant risks.

Hemodynamic measurements were performed before, during and after surgery of aneurysmal patients. Fifty non-ruptured infrarenal aneurysmal patients undergoing elective aortic reconstructions were studied. Patients who had no evidence of heart disease were divided into two groups by age. The older group consisted of 22 patients older than 70 years of age, and the younger group consisted of 28 patients younger than 70 years. The results may be summarized as follows: (1) Hemodynamics before surgery (volume loaded test): For 500 ml albumin infusion within 30 minutes, cardiac indices of the older group kept below 4.0 l/min/m2, whereas in the younger group there was an increase from 3.66 to 4.42 l/min/m2. (2) Hemodynamics during surgery: Peripheral resistance increased by cross-clamping of the aorta, and decreased after removal of the aorta, and decreased after removal of the cross clamp in both groups. Cardiac indices dropped during cross-clamping of the aorta. The older group dropped more noticeably compared with the younger group, for instance, at one minute after cross-clamping, the older group was 2.04 +/- 0.56, and the younger group was 2.44 +/- 0.56 l/min/m2. Mean pulmonary wedge pressure increased gradually during surgery in both groups. (3) Hemodynamics after surgery: The older group kept lower cardiac indices compared with the younger group, but not so noticeably. These results indicated that older patients have low cardiac function for preload and afterload change. We will be confronted by an increasing number of older patients in the near future. Hemodynamic managements of aortic reconstructions in the elderly might become important.

In this article, we reported the analysis of two severe diseases complicating pregnancy: 1,918 cases of heart disease in last 36 years and 22 cases of severe hepatitis in last 16 years. The conclusion was that on active therapy and close cooperation with cardiologist, pregnancy complicated with heart disease of grade III-IV cardiac function can be taken as an indication of Cesarean section. This operation performed at a proper time is good for the mother and also the baby. The traditional idea that Cesarean section could only be done for an obstetrical reason is not quite adequate. For primiparas with severe hepatitis, a supportive therapy with fresh blood transfusion, albumin and Cesarean section under local anesthesia might be the method of choice, its mortality rate being much lower than a vaginal delivery.

Poor weight and length gain of infants with congenital heart disease is generally considered to be related to inadequate nutritional intake, but no longitudinal data on growth and nutritional intake of such infants are available. We compared weight, length, subscapular and triceps skinfold thickness, energy and protein intake (24-h dietary intake records) as well as serum prealbumin and albumin of infants with cyanotic heart disease (n = 8) or isolated left-to-right shunt (n = 8) with those of healthy infants aged (n = 8) 45-365 days. Weight, length, and combined (subscapular and triceps) skinfold thickness of the two groups with congenital heart disease (CHD) were significantly less from 183 through 365 days of age. However, energy and protein intake was similar to that of the control group from 45 through 365 days of age. Normal serum prealbumin and albumin in the infants with CHD ruled out protein-calorie malnutrition. It is concluded that a low level of food intake was not the main cause of inadequate growth and of small subcutaneous fat stores in these two small, but homogeneous, groups of infants with CHD.

Cardiovascular and Renal function were examined in two populations of long-term insulin-dependent diabetics, those with microalbuminuria, a sign of early, subclinical nephropathy and those with clinically manifest diabetic nephropathy. In addition, clinical variables of possible importance for the occurrence and prognosis of diabetic nephropathy were analyzed. Microalbuminuria - a mean of three over-night urinary albumin excretion rates greater than 20 micrograms/min - was found in 16% of Albustix-negative, normotensive, insulin-dependent diabetics. The microalbuminurics had higher supine blood pressures than normoalbuminurics. The albumin excretion rate in microalbuminurics correlated to blood pressure at rest but not to glycosylated haemoglobin. The cardiovascular responses to five different test manoeuvres revealed more evident signs of autonomic nerve dysfunction in microalbuminurics than in normoalbuminurics. The circulatory reactions during mental stress however, were almost identical in the two subgroups. Despite similar glomerular filtration rate and renal plasma flow the albumin excretion during mental stress increased in microalbuminurics, but remained unchanged in normoalbuminurics. It is postulated that a disturbance of glomerular basement membrane permeability is a pre-requisite for the elevated albumin excretion seen in microalbuminurics. Inability to regulate glomerular haemodynamics, due to autonomic nerve dysfunction, may also be a contributing factor. Such dysfunction perhaps even explains why microalbuminurics have higher blood pressures at rest compared with normoalbuminurics. In manifest diabetic nephropathy the rate of renal functional decline correlated to arterial blood pressure, while glycemic control showed no such relation. Patients with rapidly progressive nephropathy showed higher values of growth hormone than slow progressors. In patients with diabetic renal failure, cardiac catheterization revealed reduced stroke work and elevated left ventricular end-distolic pressure during exercise. Autonomic nerve dysfunction and arterial hypertension possibly contributed to the impaired cardiac performance. The existence of a specific diabetic cardiopathy must even be considered. There was a male predominance both in subclinical and manifest diabetic nephropathy. Age at onset of diabetes was lower in micro- as compared to normoalbuminurics. Duration of diabetes had no prognostic implication in subclinical or manifest nephropathy. The mortality rate was high in patients with manifest nephropathy.(ABSTRACT TRUNCATED AT 400 WORDS)

A series is presented of 83 patients surgically explored for massive bowel infarction. Old men with previous heart disease and symptoms of peripheral atherosclerosis were primarily affected. Clinical presenting features were abdominal pain (100 per cent), peritonitis (57 per cent), shock (34 per cent) and hypothermia (26 per cent). A third-space syndrome with metabolic acidosis and uraemia was the most common physiological derangement. Age was the only factor that appeared to have influenced the surgeon's decision to perform massive bowel resection (71 years in non-resected versus 64 years in resected patients, P less than 0.006). The overall mortality rate was 71 per cent. Forty-four patients underwent massive bowel resection (mean length of remaining small bowel 60 +/- 40 cm) and twenty-four (54 per cent) survived the procedure. Axillary temperature was higher in survivors (36.7 degrees C versus 36.1 degrees C, P less than 0.03). Early postoperative total plasma protein and albumin concentrations were also higher in survivors (57 versus 46 g/l, P less than 0.005; 27 versus 22 g/l, P less than 0.02). Patients with previous symptoms of atherosclerotic disease and high pre-operative blood urea levels also had a bad prognosis. Survivors had a mean hospital stay of 57 days and parenteral nutrition had to be maintained for a mean of 34 days. The survival rate achieved with massive resection justifies this surgical approach in selected patients with massive bowel infarction.
