- A steep increase of small papillary thyroid cancers (sPTCs) has been observed globally. A major risk factor for developing PTC is ionizing radiation. The aim of this study is to investigate the spatial distribution of sPTC in Sweden and the extent to which prevalence is correlated to gamma radiation levels (Caesium-137 (Cs-137), Thorium-232 (Th-232), Uranium-238 (U-238) and Potassium-40 (K-40)) using multiple geospatial and geo-statistical methods. The prevalence of metastatic sPTC was associated with significantly higher levels of Gamma radiation from Th-232, U-238 and K-40. The association is, however, inconsistent and the prevalence is higher in densely populated areas. The results clearly indicate that sPTC has causative factors that are neither evenly distributed among the population, nor geographically, calling for further studies with bigger cohorts. Environ-mental factors are believed to play a major role in the pathogenesis of the disease.

- Objectives: Little is known about the biological processes causing aortic aneurysm rupture. Chronic Chlomydophila pneumoniae infection has been suggested as a possible contributing factor to the development and expansion of abdominal aortic aneurysm (AAA). The importance of infection in AAA may be related to the previous pathogen burden, that is, the number of significant titres of antibodies against infectious pathogens rather than to single infectious agents. The aim of this study was to examine the relationship between infectious burden and AAA rupture. Methods: In a case-control study, 119 patients with abdominal aortic aneurysm and 36 matched controls without aneurysm were prospectively investigated for specific. IgG class antibodies against C. pneumoniae, Helicobacter pylori, Cytomegalovirus, and Herpes simplex virus. Results: Patients with ruptured AAA have similar levels of pathogen burden as patients with nonruptured electively operated AAA, small AAA, and controls without aneurysm. Conclusion: The present study fails to demonstrate a connection between infectious burden and abdominal aortic aneurysm rupture. (C) 2008 European Society for Vascular Surgery.

- Ruptured abdominal aortic aneurysm (AAA) is associated with a high mortality despite surgical management. Earlier reports indicate that a major cause of immediate intraoperative death in patients with ruptured AAA is related to hemorrhage due to coagulopathy. Acidosis is, besides hypothermia and hemodilution, a possible cause of coagulopathy. The aim of the present study was to investigate the incidence of coagulopathy and acidosis preoperatively in patients with ruptured AAA in relation to the clinical outcome with special regard to the influence of shock. For this purpose, 95 consecutive patients who underwent surgery for AAA (43 ruptured with shock, 12 ruptured without shock, and 40 nonruptured) were included. Coagulopathy was defined as prothrombin time (international normalized ratio [INR]) >= 1.5 and acidosis was defined as base deficit >= 6 mmol/L. Mortality and postoperative complications were recorded. The present study shows a state of acidosis at the start of surgery in 30 of 55 patients with ruptured AAA. However, only in 7 of 55 patients with ruptured AAA a state of preoperative coagulopathy was demonstrated. Furthermore, in our patients with shock due to ruptured AAA only 2 of 12 deaths were due to coagulopathy and bleeding. Indeed, our results show a relatively high incidence of thrombosis-related causes of death in patients with ruptured AAA, indicating a relation to an activated coagulation in these patients. These findings indicate that modern emergency management of ruptured AAA has improved in the attempt to prevent fatal coagulopathy.

- Material and methods Ultra-high molecular weight polyethylene cups with a titanium mesh molded on the outside were subjected to wear using a hip simulator. Before and after wear, they were (1) imaged with a CT scanner using a phantom model device, (2) measured using a coordinate measurement machine (CMM), and (3) weighed. CMM was used as the reference method for measurement of femoral head penetration into the cup and for comparison with CT, and gravimetric measurements were used as a reference for both CT and CMM. Femoral head penetration and wear vector angle were studied. The head diameters were also measured with both CMM and CT. The repeatability of the method proposed was evaluated with two repeated measurements using different positions of the phantom in the CT scanner. Results The accuracy of the 3D CT method for evaluation of linear wear was 0.51 mm and the repeatability was 0.39 mm. Repeatability for wear vector angle was 17 degrees A degrees. Interpretation This study of metal-meshed hip-simulated acetabular cups shows that CT has the capacity for reliable measurement of linear wear of acetabular cups at a clinically relevant level of accuracy.

- Traumatic brain injury (TBI) has long-lasting consequences not only for the individual with the injury but also for family members. The aim of this study is to elucidate the meaning of family members' experiences of living with an individual with moderate or severe TBI. The data have been collected by means of qualitative research interviews with 8 family member participants. A phenomenological hermeneutic interpretation (Ricouer, 1976) of the data reveal that family members struggle with their own suffering while showing compassion for the injured person. Their willingness to assume care for the injured person is derived from their feeling of natural love and the ethical demand to be responsible for the other. Hope and natural love from close relatives, the afflicted person, and other family members give the family members strength. It is important that professionals pay more attention to the suffering of close relatives.

- We conducted a qualitative inquiry in order to describe the meaning of women's experiences of living with multiple sclerosis (MS). Multiple sclerosis is a chronic autoimmune disease of the central nervous system. The majority of persons living with MS are women. Living with MS has been described as difficult because of the uncertainty of the illness. Ten women with MS were interviewed and the interviews were analyzed with a phenomenological hermeneutic interpretation. In this study, we suggest that the meaning of living with MS for women can be understood as trying to maintain power and living with an unrecognizable body. The bodies of women with MS serve as hindrances in everyday life. Bodily changes evident to others impose feelings of being met in a different way, which can be understood as an expression of a violated

- OBJECTIVE: To investigate sex differences in symptoms, structure of symptoms, disability and life satisfaction 3 years after mild traumatic brain injury. Secondary aims were to find risk factors for adverse outcome.DESIGN: Population-based cohort study.Patients: The cohort comprised 137,000 inhabitants at risk in a defined population served by a single hospital in northern Sweden. Patients attending the emergency department following a mild traumatic brain injury in 2001 were included.METHODS: Of 214 patients aged 18–64 years, 163 answered a questionnaire on symptoms, disability, and life-satisfaction 3 years post-injury. The instruments were analysed with descriptive statistics. A principal component analysis of the Rivermead Post-Concussion Symptoms Questionnaire was conducted. Risk factors were identified using logistic regression.RESULTS: Post-concussion syndrome was found in 50% of the women and 30% of the men. Disability was found in 52% of the women and 37% of the men, and 57% of the women and 56% of the men were satisfied with their lives. For both genders, high frequency of symptoms was a risk factor for disability and low life satisfaction. Back pain was a risk factor for disability. Living alone was a risk factor for low levels of life satisfaction. The principal component analysis revealed differences between the sexes.CONCLUSION: There are sex differences in outcome 3 years after mild traumatic brain injury. Women and men should be analysed separately.

- INTRODUCTION: Abdominal aortic aneurysm is a common condition with high mortality when rupturing. However, the condition is also associated with nonaneurysmal cardiovascular mortality. A possible contributing mechanism for the thrombosis related cardiovascular mortality is an imbalance between the activation of the coagulation system and the fibrinolytic system. The aim of the present study was to investigate haemostatic markers in patients with nonruptured abdominal aortic aneurysm with special regard to the influence of aneurysm size and smoking habits. METHODS: Seventy-eight patients with infrarenal aortic aneurysm and forty-one controls without aneurysm matched by age, gender and smoking habits were studied. Thrombin-antithrombin (TAT), prothrombin fragment 1+2 (F 1+2)--markers of thrombin generation, and von Willebrand factor antigen (vWFag)--considered as a reliable marker of endothelial dysfunction--were measured. Plasma levels of tissue plasminogen activator antigen (tPAag), and plasminogen activator inhibitor type 1 (PAI-1) were measured as markers of fibrinolytic activity. D-dimer, a marker of fibrin turnover, was also measured. RESULTS: There were significantly higher levels of TAT and D-dimer in patients with abdominal aortic aneurysm. The highest level of TAT and D-dimer were detected in patients with large compared to small AAA. CONCLUSIONS: The present data indicate a state of activated coagulation in patients with abdominal aortic aneurysm which is dependent by aneurysm size. The activated coagulation in AAA patients could contribute to an increased cardiovascular risk in patients also with small AAA. The possible impact of secondary prevention apart from smoking cessation has to be further evaluated and is maybe as important as finding patients at risk of rupture.
