- Children with Down syndrome (DS) and myeloid leukaemia have a significantly higher survival rate than other children, but they also experience considerable treatment-related toxicity. We analysed data on 56 children with DS who were treated on the Nordic Society for Paediatric Haematology and Oncology-acute myeloid leukaemia (NOPHO-AML)88 and NOPHO-AML93 protocols and reviewed the literature. In the dose-intensive NOPHO-AML88 protocol, 8 out of 15 patients (53%) experienced an event. In the less dose-intensive NOPHO-AML93 protocol, 7 out of 41 patients (17%) had an event. Therapy was reduced in 29 patients (52%) with in average 75% and 67% of the scheduled dose of anthracycline and cytarabine, respectively. Treatment-related death occurred in seven who all received full treatment. Relapse and resistant disease occurred at a similar rate in those receiving full and reduced treatment. Review of major series of myeloid leukaemia of DS showed no clear relationship between dose and survival; however, it appears that both a reduction in treatment dose and a less intensively timed treatment regimen improved the outcome. Further studies are needed to define the optimal regimen for treating myeloid leukaemia of DS.

- In the Nordic Society for Paediatric Haematology and Oncology paediatric study acute myeloid leukaemia (AML) 93, event-free survival was 50% and overall survival was 66%, indicating that many patients were cured following relapse. Factors influencing outcome in children with relapsed AML were investigated. The study included all 146 children in the Nordic countries diagnosed with AML between 1988 and 2003, who relapsed. Data on disease characteristics and relapse treatment were related to outcome. Sixty-six percentage achieved remission with survival after relapse (5 years) 34 +/- 4%. Of 122 patients who received re-induction therapy, 77% entered remission with 40 +/- 5% survival. Remission rates were similar for different re-induction regimens but fludarabine, cytarabine, granulocyte colony-stimulating factor-based therapy had low treatment-related mortality. Prognostic factors for survival were duration of first complete remission (CR1) and stem cell transplantation (SCT) in CR1. In early relapse (<1 year in CR1), survival was 21 +/- 5% compared with 48 +/- 6% in late relapse. For children receiving re-induction therapy, survival in early relapse was 29 +/- 6% and 51 +/- 6% in late. Patients treated in CR1 with SCT, autologous SCT or chemotherapy had a survival of 18 +/- 9, 5 +/- 5 and 41 +/- 5%, respectively. Survival was 62 +/- 6% in 64 children given SCT as part of their relapse therapy. A significant proportion of children with relapsed AML can be cured, even those with early relapse. Children who receive re-induction therapy, enter remission and proceed to SCT can achieve a cure rate of 60%.

Tidskriftsartikel (refereegranskat)abstract
- Background Autoimmune polyendocrine syndrome type 1 (APS-1) is a multiorgan autoimmune disorder caused by mutations in AIRE, the autoimmune regulator gene. Though recent studies concerning AIRE deficiency have begun to elucidate the molecular pathogenesis of organ-specific autoimmunity in patients with APS-1, the autoantigen responsible for hypoparathyroidism, a hallmark of APS-1 and its most common autoimmune endocrinopathy, has not yet been identified. Methods We performed immunoscreening of a human parathyroid complementary DNA library, using serum samples from patients with APS-1 and hypoparathyroidism, to identify patients with reactivity to the NACHT leucine-rich-repeat protein 5 (NALP5). Subsequently, serum samples from 87 patients with APS-1 and 293 controls, including patients with other autoimmune disorders, were used to determine the frequency and specificity of autoantibodies against NALP5. In addition, the expression of NALP5 was investigated in various tissues. Results NALP5-specific autoantibodies were detected in 49% of the patients with APS-1 and hypoparathyroidism but were absent in all patients with APS-1 but without hypoparathyroidism, in all patients with other autoimmune endocrine disorders, and in all healthy controls. NALP5 was predominantly expressed in the cytoplasm of parathyroid chief cells. Conclusions NALP5 appears to be a tissue-specific autoantigen involved in hypoparathyroidism in patients with APS-1. Autoantibodies against NALP5 appear to be highly specific and may be diagnostic for this prominent component of APS-1.

- Acromegaly [overproduction of GH (growth hormone)] is associated with cardiovascular disease. Transgenic mice overexpressing bGH (bovine GH) develop hypertension and hypercholesterolaemia and could be a model for cardiovascular disease in acromegaly. The aims of the present study were to investigate the effects of excess GH on vascular function and to test whether oxidative stress affects endothelial function in bGH transgenic mice. We studied the ACh (acetylcholine)-induced relaxation response in aortic and carotid rings of young (9-11 weeks) and aged (22-24 weeks) female bGH transgenic mice and littermate control mice, without and with the addition of a free radical scavenger {MnTBAP [Mn(III)tetrakis(4-benzoic acid)porphyrin chloride]}. We also measured mRNA levels of eNOS (endothelial nitric oxide synthase) and EC-SOD (extracellular superoxide dismutase). Intracellular superoxide anion production in the vascular wall was estimated using a dihydroethidium probe. Carotid arteries from bGH transgenic mice had an impaired ACh-induced relaxation response (young, 46 +/- 7% compared with 69 +/- 8%; aged, 52 +/- 5% compared with 80 +/- 3%; P < 0.05), whereas endothelial function in aorta was intact in young but impaired in aged bGH transgenic mice. Endothelial dysfunction was corrected by addition of MnTBAP in carotid arteries from young mice and in aortas from aged mice; however, MnTBAP did not correct endothelial dysfunction in carotid arteries from aged bGH transgenic mice. There was no difference in intracellular superoxide anion production between bGH transgenic mice and control mice, whereas mRNA expression of EC-SOD and eNOS was increased in aortas from young bGH transgenic mice compared with control mice (P < 0.05). We interpret these data to suggest that bGH overexpression is associated with a time- and vessel-specific deterioration in endothelial function, initially caused by increased oxidative stress and later by other alterations in vascular function.

- Aim: To investigate the characteristics of severe abuse of children and possible differences in comparison with less severe abuse. Method: Cases of abuse reported to the police within a single police district (n = 142) in Sweden were studied. The severe cases were compared to all the remaining cases. Results: Severe abuse constituted 14% of the total cases and was reported by agencies to a greater degree than minor cases. The suspected perpetrators were socially disadvantaged people in both groups. Half of the most serious cases led to conviction in the courts, compared to 8% in the reference group. The children who had been subjected to abuse were often already known to social services and reports of child abuse had frequently been made. Conclusion: In comparison between cases of severe and minor child abuse reported to the police, the results did not show any crucial differences except the pattern of reporting and a higher occurrence of prosecution/conviction in the severe cases. This finding places a responsibility on agencies outside of the justice system to consider all cases of reported abuse as serious warning signals and to make independent evaluations to identify risks and the possible need for child protection.

- Patients come to the emergency department (ED) with complex medication and some patients present symptoms of adverse drug effects. Drug treatment is a complex process for physicians to handle. The aim of this study was to explore how a group of ED physicians view their work in relation to patients’ drug treatment. Three semi-structured focus group discussions with 12 physicians in an ED in Sweden were conducted and analysed thematically. The core theme was ‘‘limit work to here and now’’. Three descriptive themes were identified in relation to the main theme; (1) focussing to cope with work; (2) decision making on limited patient-specific information; and (3) actively seeking learning moments. The findings show that the physicians actively seek learning moments in work. Signing their own notes in the computerized medical record is a way of getting feedback on the treatment they have initiated and it was seen as a large part of their clinical education. If we want to support the physicians with new technology for safer drug treatment, such as a computerized drug prescribing support system, the support system should be adapted to the different learning styles and needs.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: A majority of doctor-patient meetings result in the patient getting a prescription. This underlines the need for a high-quality prescription process. While studies have been made on single therapeutic drug groups, a complete study of the physicians' general thought process that comprises the prescription of all drugs still remains to be made. OBJECTIVE: To identify variations in ways of understanding drug prescribing among GPs. METHODS: A descriptive qualitative study was conducted with 20 Swedish physicians. Informants were recruited purposively and their understandings about prescribing were studied in semi-structured interviews. Data were analysed using a phenomenographic approach. RESULTS: Five categories were identified as follows: (A) GP prescribed safe, reliable and well-documented drugs for obvious complaints; (B) GP sought to convince the patient of the most effective drug treatment; (C) GP chose the best drug treatment taking into consideration the patient's entire life situation; (D) GP used clinical judgement and close follow-up to minimize unnecessary drug prescribing and (E) GP prescribed drugs which are cheap for society and environmentally friendly. The categories are interrelated, but have different foci: the biomedical, the patient and the society. Each GP had more than one view but none included all five. The findings also indicate that complexity increases when a drug is prescribed for primary or secondary prevention. CONCLUSIONS: GPs understand prescribing differently despite similar external circumstances. The most significant factor to influence prescribing behaviour was the physician's patient relation approach. GPs may need to reflect on difficulties they face while prescribing to enhance their understandings.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Although research in business ethics has of late received increased attention from researchers and practitioners, little has been written on the practical effects of its implementation.The aim of the present study is, therefore, to explore the meaning and implications of business ethics from a practical perspective. To these ends, a qualitative study, mainly based on a grounded theory approach, has been carried out. The target of analysis is a corpus material derived from informants from 9 companies ranging from different sectors: 2 from the manufacturing sector, 1 company from the pharmaceutical sector and 6 companies from the financial sector.The results show that almost all the companies under consideration have set up some ethical structures for implementing their ethical practices, and lived up to the embraced ethical values in their business conduct. The results also indicate that the companies have actually responded favorably to the requirements and demands of various stakeholders.Furthermore, the emerging structures constitute the basis of a fully operative concept for organizing and implementing an ethical business conduct in organizations. This concept mainly consists of the following categories: ethics, rules, institutionalization, observing and abiding. These can all be applied separately or as a whole and as such be an instrument for measuring an organizations ethical level.
