Continuously recorded bipolar electrograms were obtained simultaneously from epi-, endo-, and mid-myocardial regions of the ischemic and normal zones of cat left ventricle in vivo after coronary occlusion, analyzed by computer, and compared to regional cyclic AMP levels. Regional cyclic AMP content was used as an index of the combined local effects of: (a) efferent sympathetic nerve discharge; ...

The course and prognosis of 16 infants and children with sick sinus syndrome associated with cardiac surgery is reviewed. The dysrhythmia was observed most ofter after extensive atrial reconstructive surgery in patients with transposition of the great arteries and with atrial septal defect. In 12 (75%) of the patients, sick sinus syndrome was detected in the immediate postoperative period. Tach...

UNLABELLED Until now, the literature about the influence of specific comorbid conditions on outcome of emergency abdominal surgery in polish elderly patients is scars. The aim of the study was to determine the prognostic role of comorbidities in patients qualified for emergency abdominal surgery. MATERIAL AND METHODS One hundred and eighty four consecutive patients(98 female and 86 male). 65 ...

BACKGROUND Episodes of paroxysmal atrial fibrillation may be precipitated by the rapid ingestion of ice-cold foods and beverages. This condition has received little research attention, and its true prevalence is poorly described. Treating physicians may not identify cold ingestion as a causal factor of paroxysmal atrial fibrillation, thus compromising both history taking and patient education. ...

Background—No proven neuroprotective treatment exists for ischemic brain injury after cardiac arrest. Mild-to-moderate induced hypothermia (MIH) is effective in animal models. Methods and Results—A safety and feasibility trial was designed to evaluate mild-to-moderate induced hypothermia by use of external cooling blankets after cardiac arrest. Inclusion criteria were return of spontaneous circ...

INTRODUCTION Acute mesenteric ischemia is a surgical emergency that entails complex, multi-modal management, but its epidemiology and outcomes remain poorly defined. The aim of this study was to perform a population analysis of the contemporary incidence and outcomes of mesenteric ischemia. METHODS This was a retrospective analysis of acute mesenteric ischemia in the state of Maryland during ...

Gastric peristaltic contractions are controlled by an intrinsic electrical pacemaker located in the mid-body along the greater curve. This study was undertaken to investigate gastric motility in long-term survivors of neonatal gastric rupture who were surgically deprived of their original pacemaker. Four patients, 1 boy and 3 girls, aged between 6 and 12 years were studied. Physiological activi...

In this paper we review the visual snow (VS) characteristics of a case cohort of 32 patients. History of symptoms and associated co-morbidities, ophthalmic examination, previous investigations and the results of intuitive colourimetry were collected and reviewed. VS symptoms follow a stereotypical description and are strongly associated with palinopsia, migraine and tinnitus, but also tremor. T...
