Elective open operation for abdominal aortic aneurysm in octogenarians--survival analysis of 105 patients.

OBJECTIVES: To study early mortality and long-term survival of patients more than 80 years of age having elective open repair for abdominal aortic aneurysm (AAA). DESIGN: Retrospective multicenter cohort study. MATERIAL: One hundred and five patients, 23 women and 82 men, with a median age of 82 years, operated at three Norwegian hospitals during the period 1983-2002. METHOD: Survival analyses were based on data from medical records and the Norwegian Registrar's Office of Births and Deaths. Expected survival was based on mortality rates of the general population, matched by age, sex, and calendar period. Relative survival was calculated as the ratio between the observed and the expected survival. RESULTS: During the study period there has been a 10 fold increase in octogenarians treated with open operation for AAA. Early mortality (30-day) for the whole group of patients was 10.5% (95% confidence interval (95% CI) 5.3-18.0), and similar for both genders. The 5-year survival rate was 47% (95% CI 35.9-57.4), and not significantly different from that of a matched group in the general population. Patients aged 84 years or more had a median survival time of 35 months (95% CI 18.5-51.6). CONCLUSION: The number of AAA operations in octogenarians has increased considerably during 20 years. Octogenarians operated electively for AAA has higher 30-day mortality as compared to younger patients. Their long-term survival appears similar to a matched control group. The benefit of surgery must be carefully considered against the perioperative risk, especially for the oldest octogenarians.     

Confrontations with reality: Crisis intervention services for traumatized families after a school bus accident in Norway

In August 1988 a Swedish schoolbus with 23 children and 11 adult passengers crashed into a tunnel wall in Norway. Twelve children and four parents died, 18 of the passengers survived. The victims' relatives (parents, spouses, siblings, and others) were transported to Norway and given a confronting support program at the University hospital in Bergen. The crisis intervention program is described: how the relatives were helped to confront and actively cope with some of the stressful situations from which traumatized families very often are protected. One year later 42 of the relatives answered a questionnaire evaluating the confronting support program that was offered during their stay in Norway. A majority of the respondents did not regret their participation in the program. The answers indicate that passivity and helplessness can be counteracted through a combination of confrontation with reality and emotional support.The study has received financial support from Skandia Insurance Co. (Sweden), Haukeland University Hospital and Norwegian Research Council for Science and the Humanities (377.92/021).     

Multicenter phase II study of Nordic fluorouracil and folinic acid bolus schedule combined with oxaliplatin as first-line treatment of metastatic colorectal cancer.

PURPOSE: This Nordic multicenter phase II study evaluated the efficacy and safety of oxaliplatin combined with the Nordic bolus schedule of fluorouracil (FU) and folinic acid (FA) as first-line treatment in metastatic colorectal cancer. PATIENTS AND METHODS: Eighty-five patients were treated with oxaliplatin 85 mg/m(2) as a 2-hour infusion on day 1, followed by a 3-minute bolus injection with FU 500 mg/m(2) and, 30 minutes later, by a bolus injection with FA 60 mg/m(2) every second week. The same doses of FU and FA were also given on day 2. RESULTS: Fifty-one of 82 assessable patients achieved a complete (n = 4) or partial (n = 47) response, leading to a response rate of 62% (95% CI, 52% to 72%). Nineteen patients showed stable disease, and 12 patients had progressive disease. Thirty-eight of the 51 responses were radiologically confirmed 8 weeks later (confirmed response rate, 46%; 95% CI, 36% to 58%). The estimated median time to progression was 7.0 months (95% CI, 6.3 to 7.7 months), and the median overall survival was 16.1 months (95% CI, 12.7 to 19.6 months) in the intent-to-treat population. Neutropenia was the main adverse event, with grade 3 to 4 toxicity in 58% of patients. Febrile neutropenia developed in seven patients. Nonhematologic toxicity consisted mainly of neuropathy (grade 3 in 11 patients and grade 2 in another 27 patients). CONCLUSION: Oxaliplatin combined with the bolus Nordic schedule of FU+FA (Nordic FLOX) is a well-tolerated, effective, and feasible bolus schedule as first-line treatment of metastatic colorectal cancer that yields comparable results compared with more complex schedules.     

Determination of paralytic shellfish poisoning toxins in Norwegian shellfish by liquid chromatography with fluorescence and tandem mass spectrometry detection.

A novel extraction and clean-up method has been developed for the determination of paralytic shellfish poisoning (PSP) toxins in shellfish samples. Raw shellfish material was extracted with an acidic acetonitrile/water (80:20, v/v) solution, whilst being homogenised. During the homogenisation the sample extraction solution was cooled with ice water. Subsequently, the extract was frozen at -20 degrees C for at least 4h. During freezing, two layers were formed, only the lower predominantly aqueous layer was used for the determination. The final extract solution was cleaned-up using a combination of Oasis HLB and Carbograph activated carbon SPE columns. The developed extraction and clean-up methods combined with gradient elution liquid chromatography (LC)-mass spectrometry/mass spectrometry (MS/MS) has resulted in a method which can determine the analogs GTX 1-5, C1-2, DcGTX 2-3, DcSTX, Neo, STX in a single analysis with an overall detection limit of 313mug STXdiHCL-eq./kg shellfish meat. The use of the developed extraction method with post-column high performance liquid chromatography (HPLC) with fluorescence detection (FLD) method provided an overall limit of detection of 89mug STXdiHCL-eq./kg shellfish meat for the same toxins. Both post-column HPLC-FLD and LC-MS/MS was used to investigate the Norwegian PSP toxin profile. It was found that the PSP toxins could be detected in shellfish samples from the Norwegian coastline for 10 months of the year, from March till December. The toxin profile consisted mainly of the carbamate toxins, GTX 1-4, Neo and STX, in terms of both concentrations and contribution to the overall toxicity. In addition, several of the n-sulfo-carbamoyl toxins were either detected in the samples at relatively low concentrations or their presence in the samples were indicated but could not be confirmed by the post-column HPLC-FLD and LC-MS/MS analyses.

Breaking the speed of the sound of loneliness: Sexual partner change and the fear of intimacy

Following a thematic analysis of responses, a qualitative study of sexuality and alcohol use was undertaken in three bars/clubs in Oslo. Interviews with two persons (one male, one female) with high rates of sexual partner change were selected for detailed interpretative and contextual analysis, the aim being to examine the underlying motives for this mode of action. The principal motivations underpinning the man's behaviour linked to sex drive, impulsivity, and opportunity. He expressed cynicism, distance, loneliness and an element of narcissism. The woman's sexual activity on the other hand was motivated by intoxication, chance, the desire to offer care, arousal, and love. The data suggest that much more than sexual pleasure is being sought in the kinds of encounters described. A basic motive underpinning this behaviour appears to be a fear of intimacy mixed with the search for a sense of self-worth.
