Successful treatment of severe accidental hypothermia with cardiac arrest for a long time using cardiopulmonary bypass - report of a case

Accidental hypothermia is defined as an unintentional decrease in body temperature to below 35°C, and cases in which temperatures drop below 28°C are considered severe and have a high mortality rate. This study presents the case of a 57-year-old man discovered drifting at sea who was admitted to our hospital suffering from cardiac arrest. Upon admittance, an electrocardiogram indicated asystole, and the patient's temperature was 22°C. Thirty minutes of standard CPR and external rewarming were ineffective in raising his temperature. However, although he had been in cardiac arrest for nearly 2 h, it was decided to continue resuscitation, and a cardiopulmonary bypass (CPB) was initiated. CPB was successful in gradually rewarming the patient and restoring spontaneous circulation. After approximately 1 month of rehabilitation, the patient was subsequently discharged, displaying no neurological deficits. The successful recovery in this case suggests that CPB can be considered a useful way to treat severe hypothermia, particularly in those suffering from cardiac arrest

Resectable adenocarcinomas in the pancreatic head: the retroperitoneal resection margin is an independent prognostic factor

Pancreatic cancer is a lethal disease, and even after assumed margin-free pancreatoduodenectomy, most patients die within few years. The aims were to evaluate the importance of standardised histopathologic assessment for adequacy of reporting and survival estimates, and to report on prognostic factors in a setting of standardised histopathologic assessment. We performed immunohistochemical evaluation, slide review, and review of histopathologic reports from all pancreatoduodenectomies at Rikshospitalet University Hospital in 1980–2004. Reports from 1998-2004 at this institution were compared with reports from all other Norwegian institutions in the same period. Standardised histopathologic assessment and reporting was found necessary to avoid underestimation of poor prognostic factors, and to avoid misdiagnosis of tumours originating from non-pancreatic tissue (ampulla, distal bile duct, duodenum). Standardised histopathology was more important than surgical volume for completeness of reporting and for reliability of survival estimates, particularly with respect to lymph node evaluation. Immunostaining for MUC1 and MUC4 identified a subgroup of patients with particularly poor prognosis. Standardised histopathologic evaluation should be a first prerequisite to assure adequate histopathology after pancreatoduodenectomy. Immunostaining may identify tumour markers potentially targetable in future adjuvant treatments for pancreatic cancer
