Effect of epidemic influenza on ketoacidosis, pneumonia and death in diabetes mellitus: a hospital register survey of 1976-1979 in The Netherlands.

The influence of epidemic influenza on hospitalizations because of influenza, pneumonia and diabetic acidosis in patients with diabetes mellitus was investigated. Data on the weekly incidence of influenza-like illness were obtained from the Continuous Morbidity Registration and the cumulative data on hospitalizations in short-stay hospitals were obtained from the National Medical Registration. Patients with duodenal ulcer were used as a control population.

Elevated serum tumor markers in patients with testicular cancer after induction chemotherapy due to a reservoir of markers in cystic differentiated mature teratoma.

Elevated serum tumor markers in patients with testicular cancer after induction chemotherapy indicate in most instances the presence of residual malignant disease. We describe 2 patients with elevated tumor markers after chemotherapy and before retroperitoneal lymph node dissection who did not prove to have residual malignant disease but cystic differentiated mature teratoma with a high content of alpha-fetoprotein and beta-human chorionic gonadotropin, respectively, in the cysts. It is postulated that leakage of the contents of these cysts to the plasma compartment was responsible for maintaining elevated serum tumor marker levels.

Estimation of myocardial ischemic injury during ventricular fibrillation with total circulatory arrest using high-energy phosphates and lactate as metabolic markers.

Study Objective: To define the time course of myocardial ischemic injury using high-energy phosphate (HEP) depletion and the cessation of lactate production as metabolic markers.

Setting: Data were collected in a laboratory animal model.

Type Of Participants: Ten immature mixed breed swine weighing 23.

No evidence for the enhanced production of insulin autoantibodies after confrontation with common viral antigens in insulin dependent diabetes mellitus.

The production of insulin autoantibodies (IAA) was studied after common viral infections in 12 children with type 1 diabetes mellitus and in their 18 healthy siblings. In addition, the production of IAA was measured after influenza vaccination with booster in 39 patients with type 1 diabetes mellitus and in 39 healthy controls. In 7 of the 12 diabetic children 13 viral infections were serologically confirmed.

Hemodynamic effects of 1-[3,4-dihydroxyphenyl]-1,2-diaminoethane versus norepinephrine during ventricular fibrillation and cardiopulmonary resuscitation.

We hypothesized that substitution of the hydroxyl group (OH) on the beta carbon of norepinephrine (NE) with an amino group would yield a compound, 1-(3,4-dihydroxyphenyl)-1,2-diaminoethane (DHPDAE), that would maintain the hemodynamic properties of NE during CPR, but would decrease the rate of post-defibrillation dysrhythmias. Six mixed breed swine weighing greater than 28 kg were studied. The animals were instrumented for cerebral (CBF) and myocardial blood flow (MBF) measurements.

[Fetal and neonatal outcome prolonged ruptured membranes in a gestational age of less than 24 weeks].

The view appears to be generally held that the survival chances of fetuses in cases of very early rupture of the membranes are low. We report a retrospective study of 12 pregnancies with prolonged rupture of the membranes less than or equal to 24 weeks menstrual age. There was no significant maternal morbidity.

The effectiveness of bystander CPR in an animal model.

Several clinical studies have yielded conflicting results in examining the effectiveness of bystander CPR (BCPR). The purpose of this pilot study was to determine the effectiveness of BCPR in an animal model of cardiac arrest and resuscitation. Ten swine were instrumented for hemodynamic and regional blood flow measurements with tracer microspheres.

Influenza infection and diabetes mellitus. Case for annual vaccination.

Herein, epidemiological data on influenza pneumonia and mortality, results of clinical studies, and the outcome of influenza vaccination trials are reviewed. All excess mortality studies that specify for underlying disease list diabetes as one of the major risk factors. During influenza epidemics, death rates among patients with diabetes mellitus may increase by 5-15%.

Effect of high dose norepinephrine versus epinephrine on cerebral and myocardial blood flow during CPR.

Several animal studies have demonstrated an improvement in cerebral blood flow (CBF) and myocardial blood flow (MBF) after the administration of epinephrine (E) 0.20 mg/kg during closed chest CPR. The administration of norepinephrine (NE) in doses of 0.

Very early prolonged premature rupture of membranes and survival.

Fetal survival is possible even with very premature rupture of membranes followed by persisting oligohydramnios, secondary Potter facies and limb deformities. A case history is given with continuous amniotic fluid loss starting at 11+4 weeks, without development of pulmonary hypoplasia.

Economic behaviour of heroin users and effects of policy measures.

The object of this study is to describe the behaviour of heroin users from an economic point of view in such a way as to enable tracing the influence of policy measures. In order to describe the heroin users' behaviour, data have been collected regarding relevant variables and relations between variables by interviewing 80 heroin users in the Netherlands. Based on these data a computer model has been developed.

Feline mammary carcinomas as a model for human breast cancer. II. Comparison of in vivo and in vitro adriamycin sensitivity.

Feline mammary carcinomas were tested for their in vitro and in vivo sensitivity to Adriamycin. In vitro, twenty randomly chosen tumor islands were studied to test the effect of concentrations of the drug ranging from 0.25-2.

Effects of splenectomy on hemodynamic performance in fixed volume canine hemorrhagic shock.

Studies of canine hemorrhagic shock commonly use a splenectomized fixed-pressure model. Splenectomy is recommended in this model to avoid variable degrees of autotransfusion that reduce the reliability of mortality estimates and blood volume measurements. The effects of splenectomy on a non-lethal fixed-volume canine hemorrhage have not been established.
