The partogram's result and neonatal outcome.

The aim was to investigate to what extent low Apgar scores are linked to the partogram's result and, more specifically, if the action line should be set 3 rather than 4 h parallel and right to the alert line. Some 24.0% of all labours evolved left to the alert line and 26.3% of the labours right to the alert line crossed the 4-h action line. An Apgar score of 相似文献   

Die „kleine“ Handverletzung im BGlichen Heilverfahren

Only a small percentage of “minor” hand injuries are treated by surgeons with a specialist training in hand surgery, partly because they are so frequent. In most cases this does not prejudice the outcome. There are, however, still patients whose treatment takes an unexpectedly long time and who are not successfully rehabilited but are left with lasting problems justifying early retirement. To face up to these problems, which are often the result of inadequate or inappropriate treatment, a model hand surgery project established as part of the treatment plan by several of the regional branches of the German employers’ liability insurance associations (Southwest Germany, Berlin, Brandenburg, Mecklenburg-Upper Pomerania, and Northwest Germany) has been in place since spring 2002. This project and the experience recorded in patients treated according to the procedures laid down for it are presented in this paper.     

Dysfunctional schemas and psychopathology in referred obese adolescents

Objective: Referred obese adolescents often display psychological problems. The present study aimed at investigating whether Young's schema theory constitutes a comprehensive framework to understand psychopathology in youth in general and in referred obese adolescents in particular. Methods: 91 youngsters referred for obesity treatment and 91 normal weight controls (all between 12 and 18 years of age) filled out the Young Schema Questionnaire and the Youth Self‐Report. Parents were asked to complete the Child Behavior Checklist. Results: The obese youngsters displayed an overall greater severity of dysfunctional schemas than normal weight controls. The obese group scored significantly higher for the schemas Emotional Deprivation, Social Isolation/Alienation, Defectiveness/Shame, Failure to Achieve, Dependence/Incompetence and Subjugation. Social Isolation/Alienation and Vulnerability to Harm/Illness were highly predictive for internalizing symptoms in youth. The schemas Entitlement and Dependence/Incompetence were predictive for externalizing symptoms in youth. Conclusion: Referred obese individuals display high levels of maladaptive schemas and these are generally related to internalizing and externalizing symptoms.

Endogenous brain Na pumps, brain ouabain-like substance and the alpha2 isoform in salt-dependent hypertension.

An endogenous ouabain-like substance (OLS) plays a critical role in the etiology of experimental models of human hypertension induced by a high salt diet. Early on, evidence for a role of this Na, K-ATPase inhibitor in blood pressure regulation was provided mainly by correlations of blood pressure with the levels of circulating Na, K-ATPase inhibitor. However, over the past decade, numerous studies have shown that endogenous Na pump inhibitors in the brain mediate salt-dependent hypertension in a variety of experimental models, including Dahl salt-sensitive (Dahl-S) and spontaneously hypertensive (SHR) rats on a high-salt diet. Other forms of hypertension that are known to be mediated by endogenous ouabain-like substances include steroid/salt- (e.g., DOCA-salt) and ACTH-induced hypertension. Even when exogenous ouabain is peripherally administered and/or the plasma ouabain/OLS level is increased in rats, the resulting hypertension is of CNS origin. After peripheral ouabain administration, ouabain levels increase in the plasma and the inhibitor subsequently accumulates in the brain. The ensuing hypertension is abolished by the intracerebroventricular (icv) administration of an anti-ouabain antibody (but not by the same antibody dose given iv), by discrete excitotoxic lesions in the brain or by ganglionic blockade, demonstrating that the response is neurally mediated. The pressor response to stimuli that increase the brain OLS (high salt diet, icv sodium) or to icv ouabain is abolished by icv losartan, demonstrating that the brain OLS activates the brain renin-angiotensin system (RAS) downstream. There are three isoforms of the catalytic alpha subunit of the Na, K-ATPase in the brain and cardiovascular system (alpha1, alpha2 and alpha3), but it is not known which brain isoform(s) mediate the hypertensive effects of circulating/CNS ouabain. Preliminary studies in gene-targeted mice suggest that the alpha2 isoform plays a critical role.     

Dopamine compared with dobutamine in experimental septic shock: relevance to fluid administration

The hemodynamic effects of dopamine and dobutamine (at doses of 6 micrograms X kg-1 X min-1) were compared during fluid resuscitation from septic shock induced by endotoxin (3 mg/kg) in the dog. In the first part of the study, when a standard amount of saline solution was infused (in 24 dogs), dopamine infusion resulted in higher cardiac filling pressures than did dobutamine infusion, whereas dobutamine infusion resulted in higher cardiac output. In the second part of the study, when fluid infusion was titrated to maintain pulmonary artery balloon-occluded pressure at constant level (in 24 dogs), the total amount of fluids was significantly greater with dobutamine than when dopamine was used (109 +/- 13 vs 71 +/- 10 ml/kg). The combination of dobutamine with fluids resulted in significantly greater stroke volume (39.6 +/- 3.8 vs 21.0 +/- 4.0 ml, P less than 0.05) and oxygen consumption (194 +/- 18 vs 144 +/- 8 ml/min, P less than 0.05). The different effects of dopamine and dobutamine on cardiac filling pressures can be due to differences in effects on myocardial contractility, ventricular afterload, and cardiac compliance. This experimental study indicates that when fluid therapy is combined with adrenergic agents in resuscitation from septic shock, dobutamine can be associated with higher cardiac output and oxygen transport and can result in higher tissue oxygen consumption than dopamine.     

Tight nuchal cord and neonatal hypovolaemic shock.

Two neonates who went into acute hypovolaemic shock due to a tight nuchal cord were successfully resuscitated. The occurrence of this life threatening complication in two low risk pregnancies emphasises the importance of having staff trained in resuscitation immediately available in the delivery unit.
