- Thromboembolism during pregnancy is a rare complication with a potential fatal outcome. Very little is known about long-term effects and therefore 104 women with thrombosis during pregnancy or puerperium were identified and their subjective complaints were assessed in a questionnaire. All had their thrombosis diagnosed by objective methods and the median follow-up time was 11 years. In spite of anticoagulant treatment only 22% were without complaints; 4% had ulceration, all occurring in the group with thrombosis during pregnancy. Significantly more women who had had their thrombosis during pregnancy used compression bandages than those who had their thrombosis during puerperium. The severity of the symptoms increased with the increasing number of thromboses. Anticoagulant therapy of the acute episode does not appear to alter the degree of long-term handicap in the lower limbs.

Islet cell antibody reactivity with human fetal pancreatic islets
- 1991
-
Ingår i: Diabetes Research and Clinical Practice. - 0168-8227. ; 14:1, s. 1-7

Tidskriftsartikel (refereegranskat)abstract
- To evaluate the possibility of autoimmune processes against pancreatic islets in fetal life, we tested islet cell antibody (ICA) reactivity with 14 fetal pancreata obtained after abortion at the 15th up to the 19th week of gestation. Pancreatic islets positive for a monoclonal proinsulin antibody but non-reactive with ICA negative control serum were found in 9 14 pancreata and all ( 9 9) of them showed a positive reaction with the ICA standard. It is concluded that ICA reactivity may be detected in fetal human pancreata. Further studies on fetal islet cell antibody reactivity in the development of insulin dependent diabetes mellitus (IDDM) are warranted.

- Objectives. To estimate the incidence of fatal colonic ischaemia (CI) and the cause-specific mortality of CI, and to describe the localization and extension of colonic infarction and quantify the risk factors associated with CI. Material and methods. Between 1970 and 1982 the autopsy rate in Malmo, Sweden, was 87%, creating the possibilities for a population-based study. Out of 23,446 clinical autopsies, 997 cases were coded for intestinal ischaemia in a database. In addition, 7569 forensic autopsy protocols were analysed. In a case-control study nested in the clinical autopsy cohort, four CI-free controls, matched for gender, age at death and year of death, were identified for each fatal CI case in order to evaluate the risk factors. Results. The cause-specific mortality ratio was 1.7/1000 autopsies. The overall incidence of autopsy-verified fatal CI was 1.7/100,000 person years, increasing with age up to 23/100,000 person years in octogenarians. Fatal cardiac failure (odds ratio (OR) 5.2), fatal valvular disease (OR 4.3), previous stroke (OR 2.5) and recent surgery (OR 3.4) were risk factors for fatal CI. Narrowing/occlusion of the inferior mesenteric artery (IMA) at the aortic origin was present in 68% of the patients. The most common segments affected by transmural infarctions were the sigmoid (83%) and the descending (77%) colon. Conclusions. Heart failure, atherosclerotic occlusion/stenoses of the IMA and recent surgery were the main risk factors causing colonic hypoperfusion and infarction. Segments of transmural infarctions were observed within the left colon in 94% of the patients. Awareness of the diagnosis and its associated cardiac comorbidities might help to improve survival.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of the present population-based study was to assess the trends of age- and gender-specific incidence of ruptured abdominal aortic aneurysm (rAAA). Methods. Patients with rAAA from the city of Malmo, Sweden, were studied between 2000 and 2004. An analysis of trends of incidence and mortality of rAAA in Malmo was possible because of a previous population-based study on patients with rAAA between 1971 and 1986 (autopsy rate 85% compared with 25% for the time period 2000 to 2004). The in-hospital registry of Malmo University Hospital and the databases at the Department of Pathology, Malmo, and the Institution of Forensic Medicine, Lund, identified patients with rAAA, and the in-hospital registry identified all elective repairs for AAA. Results. Compared with the time period 1971 to 1986, the overall incidence of rAAA significantly increased from 5.6 (95 % confidence interval [CI], 4.9 to 6.3) to 10.6 (95% CI, 8.9 to 12.4) per 100,000 person-years (standardized mortality ratio, 1.6; 95% CI, 1.0 to 2.1). In men aged 60 to 69 and 70 to 79 years, the incidence increased significantly from 16 (95% CI, 11 to 21) and 56 (95% Cl, 43 to 69) to 46 (95% Cl, 28 to 63) and 117 (95% CI, 84 to 149) per 100,000 person-years, respectively, whereas no increase in the age-specific incidence in women could be demonstrated. The overall incidence of elective repair of AAA increased significantly from 3.4 (95% CI, 2.8 to 4.0) to 7.0 (95% CI, 5.6 to 8.4) per 100,000 person-years and increased most significantly from 12 (95% CI, 3.4 to 32) to 68 (95% CI, 34 to 102) per 100,000 person-years in men aged 80 to 89 years and from 5.1 (95% CI, 2.4 to 9.3) to 28 (95% CI, 15 to 41) per 100,000 person-years in women aged 70 to 79 years. The elective-acute repair ratio in women increased from 2.4 to 5.6 and decreased in men from 2.1 to 1.0. Conclusions: Between 1971 to 1986 and 2000 to 2004, the incidence of rAAA increased significantly, despite a 100% increase in elective repairs and notwithstanding a potential for bias towards underestimation due to lower autopsy rates in recent years. The reason behind this increase is unclear, and further studies are needed to identify risk groups for direction of effective prevention and screening.

Forskningsöversikt (refereegranskat)abstract
- Background. The aims of the present study were to (1) analyze preoperative predictors for outcome suggested by Hardman and surgical mortality after open repair and endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (rAAA), and (2) further evaluate the Hardman index in a systematic review. Methods. Patients operated on for rAAA during a 5-year period between 2000 and 2004 were scored according to Hardman-1 point for either age > 76 years, loss of consciousness after presentation, hemoglobin < 90 g/L, serum creatinine > 190 mu mol/L or electrocardiographic (ECG) signs of ischemia-with blinded evaluation of ECGs by a specialist in clinical physiology. The results were included in a systematic review of studies evaluating the Hardman index. Results: In-hospital mortality after operation was 41% (67/162). There was no difference in in-hospital mortality between open repair (n=106) and EVAR (n=56), whereas the Hardman index was associated with operative mortality in our institution and in the systematic review of 970 patients (P <.001). Mortality rate in patients with Hardman index >= 3 was 77% in the pooled analysis. A full data set of all five scoring variables was obtained in 94 (58%) of 162 patients in our study, and potential underscoring was thus possible in 68 patients. Of the available ECGs, 12 (8.7%) of 138 were judged nondiagnostic. Five studies did not state their missing data on ECG and hemoglobin and serum creatinine concentrations, nor did they specify the criteria for ECG ischermia. Conclusions: A strong correlation between the Hardman index and mortality was found. A Hardman index >= 3 cannot be used as an absolute limit for denial of surgery. The utility of the Hardman index seems to be impeded by variability in scoring resulting from missing or nondiagnostic data.

Safety assessment of new antithrombotic agents : Lessons from the EXTEND study on ximelagatran.
- 2009
-
Ingår i: Thrombosis Research. - : Elsevier BV. - 0049-3848 .- 1879-2472. ; 123:3, s. 488-497

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Ximelagatran, the first oral direct thrombin inhibitor, was shown to be an effective antithrombotic agent but was associated with potential liver toxicity after prolonged administration. OBJECTIVES AND METHODS: The aim of the EXTEND study was to assess safety and efficacy of extended administration (35 days) of ximelagatran or enoxaparin for the prevention of venous thromboembolism after elective hip replacement and hip fracture surgery. A follow-up period, including assessment of liver enzymes (in particular alanine aminotransferase; ALAT), until post-operative day 180 was planned, with visits at days 56 and 180. RESULTS: Randomization and administration of study drugs were stopped following a report of serious liver injury occurring 3 weeks after completion of ximelagatran treatment. At the time of study termination, 1158 patients had been randomized and 641 had completed the 35-day treatment; with 303 ximelagatran and 265 enoxaparin patients remaining in the study through to the day 56 follow-up visit. Overall, 58 patients showed an ALAT increase to >2x upper limit of normal: 31 treated with enoxaparin, 27 with ximelagatran. Three ximelagatran patients also showed symptoms potentially related to liver toxicity. Eleven ximelagatran patients showed an ALAT increase after study treatment ended. The clinical development of ximelagatran was terminated and the drug withdrawn from the market. Evaluation of the relative efficacy of the two treatments as specified in the protocol was impossible due to the premature termination of the study. CONCLUSIONS: Prolonged administration of ximelagatran was associated with an increased risk of liver toxicity. In a substantial proportion of patients, ALAT increase occurred after treatment withdrawal. The findings seen with ximelagatran should be considered when designing studies with new antithrombotic agents.

Alveolar mast cells shift to an FcεRI-expressing phenotype in mild atopic asthma: a novel feature in allergic asthma pathology.
- 2011

Ingår i: Allergy. - : Wiley. - 1398-9995 .- 0105-4538. ; 66:12, s. 1590-1597

Tidskriftsartikel (refereegranskat)abstract
- Background: A unique feature of alveolar mast cells is their low high-affinity IgE receptor (FcεRI) expression. Recent discoveries in uncontrolled asthma suggest that the appearance of FcεRI-expressing alveolar mast cells may be a novel disease-specific feature of allergic asthma. This study investigates whether increased FcεRI-expressing alveolar mast cells are present in patients with mild allergic asthma or even in non-asthmatic allergic rhinitis patients (AR) who have developed bronchial hyperactivity (BHR). Methods: Bronchial and alveolar tissues were obtained from healthy controls, AR patients with or without BHR, and AR patients with concurrent asthma. Samples were processed for immunohistochemical identification of MC(T) and MC(TC) and expression of FcεRI and surface-bound IgE. Results: Bronchial mast cell expression of FcεRI was high in all groups. In contrast, in the alveolar tissue, the expression of FcεRI on mast cells was low in healthy controls and in the AR patient groups, whereas a high expression was present in AR patients with concurrent asthma (P = 0.006 compared to controls). The asthmatics had a 29-fold increase in numbers (P = 0.006) and a 19-fold increase in proportion (P = 0.007) of alveolar mast cells that expressed surface-bound IgE. Conclusions: The present data show that alveolar mast cells in patients with mild atopic asthma, but not atopic patients with AR, have turned into a highly FcεRI- and IgE-expressing phenotype. These data support the hypothesis that increased FcεRI expression on alveolar mast cells is a novel disease-specific feature of allergic asthma that is important for understanding asthma phenotypes and designing new therapeutic strategies.

A population based screening of abdominal aortic aneurysms (AAA)
- 1991
-
Ingår i: European Journal of Vascular Surgery. - 0950-821X. ; 5:1, s. 53-57
-
Tidskriftsartikel (refereegranskat)abstract
- The prevalence of abdominal aortic aneurysm (AAA) in a defined population of elderly men and its correlation to some risk factors were studied in the population cohort "men born in 1914 from Malmo". A total of 499 were invited to attend and 375 (75%) did so. The aorta could be visualised with ultrasound in 364 patients, 39 (10.7%) of whom had aneurysmal changes. The presence of an AAA was related to the findings at a general health examination undertaken 5 years previously. Tobacco and alcohol consumption, impaired lung function and a history of angina pectoris were related to the presence of an AAA. No relationship was found between an AAA and hypertension, hyperlipidaemia or hyperglycaemia. A decreased tissue elasticity as a common denominator for the lung function impairment and development of AAA is discussed.

- AIM: Endovascular skills are an integral part of modern-day vascular surgery. The STRESS machine has been developed to test these skills in vascular surgeons. This study aims to define an optimal pass/fail cutoff value for the STRESS test score. METHODS: The STRESS machine consists of a dry glass model of the abdominal aorta and its tributaries with various stenotic lesions, elongations, and tortuosities. A camera and computer software are used to simulate plain fluoroscopy-mode. The test subjects are given two assignments after which two reviewers use a combination of the ICEPS and MRS to produce the final total score; 43 subjects were tested. According to previous endovascular experience, subjects were classified into four groups: novice-low (no experience, less than 11 performed procedures, less than 50 assisted procedures), novice-high (11-25 performed procedures, more than 50 assisted procedures), intermediate (1-10 performed and >11-25 assisted procedures, 11-25 performed and >1-10 assisted procedures or 25-50 performed procedures) and advanced (more than 50 performed procedures). RESULTS: Test-score and noted experience showed a correlation of 0.794. All intermediate and advanced test subjects scored more than 50 points compared to 4 out of 15 novices. CONCLUSION: We demonstrated that it is possible to determine an optimal cut-off value for competence testing with the STRESS machine.

Abdominal aortic aneurysm and new WHO criteria for screening
- 2013

Forskningsöversikt (refereegranskat)abstract
- Does screening of abdominal aortic aneurysm (AAA) fulfil the recently revised the World Health Organization WHO criteria for screening? Contemporary data from the literature are used to analyze whether the ten recent WHO criteria can be used to motivate AAA screening. Although the prevalence of AAA seems to decrease, at least screening of 65-year old males saves lives and is cost-effective. Ultrasonographic screening for AAA in risk populations fulfils the new WHO criteria for screening.

Abdominal aortic aneurysm--to screen or not to screen

- With the ten WHO criteria for a screening program to be started, screening for abdominal aortic aneurysm is analyzed. Most of the criteria are fulfilled concerning the 65-year old male population, whereas concerning females we need more knowledge. Still the aneurysmal diameter is the most important factor to select patients for treatment meaning that many aneurysms are treated where rupture should never have occurred. Research projects giving more information on pathophysiological processes behind expansion and rupture should have priority.

Tidskriftsartikel (refereegranskat)abstract
- This paper deals with aneurysmal disease, primarily when localized in the abdominal aorta. It is based on the Olof Rudbeck lecture 2009. Aneurysm is a localized widening of an artery, and its definition has become an important issue today when the disease is in focus for screening programmes. Aetiology and pathogenesis are still poorly understood, but a genetic component determining the strength of the aortic wall is important, and there is a strong male dominance. Historically, several attempts have been made to treat the disease, but reconstructive treatment has been possible only since 1951, in an increasing number of cases performed endovascularly. By early detection through screening, and thereby the possibility to treat before rupture, it has now become possible to decrease the total mortality from the disease in the population.

- Antimicrobial treatment to attenuate expansion of abdominal aortic aneurysm has been suggested, especially with the focus on Chlamydophila. In this systematic literature review only four randomized trials were identified. In two small studies there is an indication of an effect of roxithromycin. In conclusion, however, more studies are needed, and they must be properly sized based on power calculations as well as antimicrobially relevant. Such trials are on the way both in Europe and the US, the results being awaited with interest.

- BACKGROUND: StepIt is a device for active movement of the foot that simulates normal walking with calf muscle contractions. METHODS: In 40 healthy volunteers with predominantly office work and sitting conditions, StepIt was used regularly for 1 day, and the volume of the calf, approximated to a truncated cone, was measured before and after using StepIt. One leg was used as a control, and after 5 days, the exercise was repeated, with the other leg as the control. RESULTS: The volume of the leg increased during the day and the increase was significantly smaller in the leg that used StepIt. CONCLUSIONS: By using a device for active foot movement in healthy people, it is possible, in some individuals, to reduce the swelling that occurs during sitting conditions.
