The diving response is initiated by apnea and facial immersion in cold water and includes, besides bradycardia, peripheral vasoconstriction, while cerebral perfusion may be enhanced. This study evaluated whether facial immersion in 10 degrees C water has an independent influence on cerebral perfusion evaluated as the middle cerebral artery mean flow(More)
AIMS/HYPOTHESIS Reports on a putative synergism between poor glycaemic control and carriage of the angiotensin II type 1 receptor (AGTR1) C1166-allele and risk of diabetic nephropathy have been conflicting. Therefore, we investigated the interaction between long-term glycaemic control and three polymorphisms in the genes coding for AGTR1 (A1166-->C),(More)
INTRODUCTION Ischemic preconditioning enhances ergometer cycling and swimming performance. We evaluated whether ischemic preconditioning of one forearm (four times for 5 min) also affects static breath hold and underwater swimming, whereas the effect of similar preconditioning on ergometer rowing served as control because the warm-up for rowing regularly(More)
The article documents that among patients with saphenofemoral reflux inadequate surgery on the saphenofemoral junction was the cause of recurrence in 40% and 43% respectively of patients treated at hospitals and in out-clinics, but in only 14% when operation was performed by a specialized vascular surgeon. The causes of recurrence are described in the(More)
Venous gas embolism is common after laparoscopic surgery but is only rarely of clinical relevance. We present a 52 year old woman undergoing laparoscopic treatment for liver cysts, who also underwent cholecystectomy. She was successfully extubated. However, after a few minutes she developed cardiac arrest due to a venous carbon dioxide (CO2) embolism as(More)
Free diving is associated with extreme hypoxia. This study evaluated the combined effect of maximal static breath holding and underwater swimming on plasma biomarkers of tissue hypoxemia: erythropoietin, neuron-specific enolase and S100B, C-reactive protein, pro-atrial natriuretic peptide, and troponin T. Venous blood samples were obtained from 17 competing(More)
The risk of complications to acute myocardial infarction (AMI), such as cardiogenic shock, is 5-10%. The cause is often left heart failure and sometimes right heart failure, but it can be mechanical AMI complications (MCA) in the form of rupture of the left ventricle and papillary muscle rupture. This risk of MCA can be reduced by sufficient(More)
