- BACKGROUND AND PURPOSE: The aim of this study was to conduct a population-based epidemiological survey among young adults aged 18 to 44 years in Northern Sweden and furthermore to gain further insight into the etiology of ischemic stroke in this age group.METHODS: Two studies were done. In the first part, epidemiological data were collected to calculate incidence and mortality from 1991 through 1994. This was based on the World Health Organization Northern Sweden MONICA register of acute stroke events. Eighty-eight first-ever ischemic stroke patients were identified during that period. In the second part, 107 consecutive patients aged 18 to 44 years with ischemic stroke referred to a university hospital were studied prospectively during a 5-year period and were extensively evaluated according to a standardized protocol. On the basis of modified Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria, the patients were classified into eight subtypes of ischemic stroke.RESULTS: The average population-based annual incidence rate for ischemic stroke (cases per 100,000 per year) was 11.3 (95% confidence interval, 6.7 to 16.1). The case-fatality rate was 5.7%. According to the modified TOAST criteria, a probable cause of ischemic stroke was identified in 36% and remained unexplained in 21% of cases. Spontaneous cervical arterial dissection was the leading probable etiology (13%). Patent foramen ovale or atrial septal aneurysm was a possible cause of stroke in 28% of cases. The percentages of ischemic stroke attributed to IgG anticardiolipin antibodies (4.7%), atherothrombotic vasculopathy (3.7%), oral contraceptive use (7%), and migraine (1%) were lower than reported in recent clinical series.CONCLUSIONS: The incidence rate for ischemic stroke was higher than previously reported from most countries in Western Europe. The higher incidence was not explained by a higher prevalence of premature atherosclerotic vasculopathy. Without the additional diagnostic information derived from advanced cardiac imaging, the proportion of indeterminate cases would have constituted 37% of the patients.

- A therapeutic removal of antibodies may be achieved by immunoadsorption (IA) or by plasma exchange (PE). The aim of this prospective randomised study was to compare the efficacy of these different techniques with regard to treatment of patients with rapidly progressive glomerulonephritis (RPG) having at least 50% crescents. Forty-four patients with a RPG were included for treatment either by IA or PE (with albumin as substitution for removed plasma). All patients were additionally treated with immunosuppression. A median of 6 sessions of PEs were performed in 23 patients compared with 6 IAs in 21 patients. Goodpasture's syndrome (GP) was present in 6 patients (PE 3, IA 3). All of them started and ended in dialysis, two died. Among the remaining 38 patients (26 men, 12 women) 87% had antibodies to ANCA. Creatinine clearance for PE versus IA were at a median at start 17.1 and 19.8 ml/min, and at 6 months 49 and 49 ml/min, respectively. At 6 months 7 of 10 patients did not need dialysis (remaining: IA 0/5 and PE 2/5, n.s.). The extent of improvement did not differ between the groups. Three patients died during the observation period of 6 months (IA 2; PE 1, on HD). Although no difference was found between the IA or the PE group this study shows that the protocol used was associated with an improved renal function in most patients (except for Goodpasture's syndrome) whereas 70% of them could leave the dialysis program.

- The article consists in a case report of a patient with rapidly progressive pain in the axillary region and deterioration in his clinical condition during the course of a skin infection, found to have pectoral muscle fascitis, and in whom progressive septic shock was accompanied by multiorgan failure. Blood culture yielded streptococci group A type 1 M1. In addition to conventional intensive care, he was treated with antibiotics, inotropic drugs, plasma exchange, and infusion of antithrombin and immunoglobulin. Surgical intervention such as fasciotomy was avoided initially and later proved unnecessary as the patient recovered well.

- OBJECTIVE: To investigate whether differences in serum lipids, diet, plasma vitamins or other risk factors explain the higher incidence of cardiovascular disease in the northern parts of Sweden, compared to Göteborg on the west coast. DESIGN: A comparison between the two Swedish MONICA populations in northern Sweden (NSW) and in Göteborg (GOT) in 1990. SETTING: Norrbotten and Västerbotten counties in the north of Sweden and the city of Göteborg on the west coast. SUBJECTS: In the north 1583 men and women aged 25-64 years were investigated, and in Göteborg 1574 men and women. Plasma vitamins were examined in a subsample of men aged 40-49 (n = 259). MAIN OUTCOME MEASURES: Serum lipids, blood pressure, anthropometric measurements, smoking habits, physical activity, diet, education, and plasma vitamins. RESULTS: NSW men and women had mean serum total cholesterol of 6.30 (standard deviation 1.23) mmol L-1 and 6.12 (1. 33) mmol L-1, compared to 5.75 (1.14) mmol L-1 and 5.67 (1.24) mmol L-1 in GOT men and women (P = 0.0001). NSW men and women were shorter and had higher body mass index than in Göteborg. Cigarette smoking was slightly more prevalent amongst GOT men and women. Göteborg men and women more often had more than compulsory school education, compared to NSW men and women, whereas there were no differences in physical activity during leisure time. There were no differences in vegetable consumption, whereas fruit was consumed more frequently by NSW women compared to GOT women, with a higher intake of fibre and ascorbate. Consumption of wine and total alcohol consumption were higher in Göteborg, whereas NSW men and women drank significantly more coffee. In the subsample of men (aged 40-49) who had plasma vitamins measured, men in Göteborg had slightly higher mean retinol concentrations (P = 0.005) and lutein and zeaxanthine levels (P = 0.006 and 0.009, respectively) compared to northern men, but there were no differences with respect to alpha- or beta-carotene, ascorbic acid or lipid-adjusted vitamin E. NSW men had slightly higher plasma iron and magnesium concentrations (P = 0.005 and 0.001, respectively). CONCLUSION: The largest and most consistent differences between Göteborg and northern Sweden were found for serum cholesterol, probably reflecting differences in intake of saturated fat. The differences in serum cholesterol may explain a substantial part of the differences in coronary heart disease morbidity and mortality. We found no consistent differences concerning vegetable and fruit consumption. More alcohol was consumed in Göteborg. Differences in education and childhood conditions, as reflected in differences in height, may contribute to the north-south gradient with respect to CHD incidence and mortality.

- Multiorgan failure (MOF) due to intoxication, trauma or sepsis in the progressive late stages always include acute renal failure (ARF). The prognosis of these patients is poor despite adequate dialysis. This study included 27 consecutive patients (20 men and 7 women, age range 15-77 years) with a rapid progress of MOF including ARF, who were treated by plasma exchange as an attempt to reverse the progress of MOF. Twenty-three of the patients suffered from a septic shock. Oliguria or anuria was present in all, dialysis was performed in 16 of them, and mechanical respiratory aid in 17. Plasma exchange was performed 1-10 times and almost exclusively by centrifuge technique, using albumin and/or liquid stored plasma (in a few cases fresh frozen plasma) as colloidal replacement fluid. Twenty-two patients survived (81%) and 5 patients died. The reasons of death were cerebral haemorrhagia, brain abscess, myocardial sudden death, relapsing sepsis from multiple hepatic abscesses and a not drained psoas abscess. All survivors could leave hospital recovered from renal failure with few other sequelae. The plasma exchange technique is easy to perform despite low blood pressures by using a vein to vein access. Plasma exchange, therefore, may be tried to reverse late stages of multiorgan failure.

- BACKGROUND AND PURPOSE: Leptin, important for body weight regulation, may be involved in the pathogenesis of the insulin resistance syndrome, associated with cardiovascular disease. We tested to determine whether leptin is a risk marker for first-ever stroke in a nested case-referent study.METHODS: We identified 113 patients with first-ever stroke (94 with ischemic and 19 with hemorrhagic stroke) who, before the stroke, had participated in population-based health surveys in northern Sweden. Referents were matched for sex, age, date and type of health survey, and geographic region. Blood pressure (BP), body mass index (BMI), and presence of smoking, diabetes, and hypertension were recorded. Total cholesterol, insulin, and leptin were analyzed in stored samples. Risk markers for first-ever stroke were analyzed by conditional logistic regression analysis.RESULTS: Patients with hemorrhagic stroke had higher levels of BMI and systolic and diastolic BPs. Leptin levels were 72% and 59% higher in males and females, respectively, with hemorrhagic stroke versus referents. Patients with ischemic stroke more often had hypertension, diabetes mellitus, and higher fasting glucose and insulin levels. A diagnosis of hypertension and elevated systolic and diastolic BPs were significant risk markers for first-ever hemorrhagic stroke in univariate analysis. High leptin (OR=20.55; 95% CI, 1.12 to 376.7) levels together with hypertension (OR=16.28; 95% CI, 1.49 to 177.3) remained as significant risk markers in a multivariate model. The combination of high leptin and high systolic or diastolic BP were associated with a profoundly increased risk for hemorrhagic stroke (OR=22.11; 95% CI, 1.57 to 310.9). Diabetes, hypertension, and obesity (BMI >/=27), together with high levels of insulin, glucose, systolic and diastolic BP, were significant risk markers for first-ever ischemic stroke in univariate analysis. Hypertension (OR=2.10; 95% CI, 1.14 to 3.86) remained as an independent risk marker in a multivariate model.CONCLUSIONS: Plasma leptin is strongly associated with an increased risk for first-ever hemorrhagic stroke, independent of other risk markers for cardiovascular disease. Leptin may be an important link in the development of cardiovascular disease in obesity.

- The occurrence of different life-style patterns, including marital status, educational level, nutrition, tobacco and alcohol use, and frequency of physical activity, in patients with oral lichenoid reactions (OLR) in total or partial contact with amalgam fillings was examined. When compared with an age- and sex-matched control group, the daily intake of carbohydrates, fibers, and iron was statistically significantly higher in the OLR patients. Regarding marital status, there was a statistically significant difference between the OLR patients and the control subjects, the former group containing more people who were divorced or whose spouse had died. The frequency of physical activity was also statistically significantly higher in the OLR patients than in the control group. Hypothetical mechanisms that may lie behind the results obtained are discussed.
