[Spinal cord infarction]. / Mænudrep.

Spinal cord infarction is a rare disease. The disorder is well known as a result of aorta atherosclerosis or complication of aorta surgery. The disorder can mimic other diseases and be difficult to diagnose. We describe a special case of a patient with idiopathic spinal cord infarction. Symptoms and prognosis of the disorder will also be discussed. Key words: Spinal cord infarct, case report, MRI, spinal cord diseases.

Incidence of multiple sclerosis in Iceland, 2002-2007: a population-based study.

BACKGROUND: We conducted a study to determine the incidence of multiple sclerosis (MS) among the whole Icelandic population during a 6-year period (2002-2007). METHODS: We included all Icelandic residents diagnosed with MS during the study period. Cases were identified from records of the only neurology department in Iceland, plus the records of all practicing neurologists and all radiology departments. All patients had experienced at least two confirmed MS relapses (i.e. clinically definite MS) or had primary progressive MS as defined by the Poser criteria. RESULTS: We identified 136 individuals who met the inclusion criteria, including 102 (75%) women. The mean age at diagnosis was 36.3 years (women 35.7 years, men 38.3 years). Average annual incidence was 7.6 per 100,000 population. All but one patient (99%) had an MRI study done at diagnosis and 61% of these (83/135) fulfilled the Barkhof criteria for diagnosis of MS; one had a normal MRI. A visual evoked potential test was done in 68% (93/136) at the time of diagnosis and 44% (41/93) were abnormal. Spinal fluid was obtained from 78% (106/136), and 75% (80/106) had oligoclonal bands. CONCLUSION: A total population study is the most reliable method of determining the spectrum of clinical symptoms and the results of investigations in MS patients at diagnosis.

[The effect of maternal weight on pregnancy outcome]. / Áhrif þyngdar verðandi mæðra á meðgöngu, fæðingu og nýbura.

OBJECTIVE: To examine the frequency of adverse outcome during pregnancy and delivery and neonatal complications among normal weight, overweight and obese women at the beginning of pregnancy. MATERIAL AND METHODS: The study is a retrospective cohort study of 600 women, divided in 3 groups on the basis of maternal body mass index (BMI) at the beginning of pregnancy; 300 normal weight women (BMI 19.0-24.9), 150 overweight women (BMI 25.0-29.9) and 150 obese women (BMI ≥ 30). Maternal and neonatal complications were compared between groups. RESULTS: Obese women have a significantly increased risk of; essential hypertension prior to pregnancy (p<0.001), developing gestational hypertension (p=0.03), pre-eclampsia (p=0.007), gestational diabetes (p<0.001), musculoskeletal symptoms (p=0.04), requiring induction of labour (pp=0.006) and being delivered by cesarean section (p<0.001), both emergent (pp=0.012) and elective (pp=0.008) compared to mothers of normal weight and overweight. Neonates of obese mothers have significantly higher birth weight (pp=0.004), larger head circumference (p<0.001) and are more likely to require admission to neonatal ward compared with neonates of normal weight and overweight mothers (pp=0.004). CONCLUSIONS: Obesity carries a significant risk to maternal and neonatal health. During pregnancy maternal complications are increased causing adverse effects for both mother and infant. Women of reproductive age need counselling regarding the adverse effects of obesity on pregnancy outcome.

[Multiple sclerosis--symptoms, diagnosis and treatment]. / Multiple sclerosis--yfirlit um einkenni, greiningu og medferd.

Multiple sclerosis is an inflammatory disease of the central nervous system and a common cause of disability among young people. MS is thought to be an autoimmune disease involving both inheritance and environmental factors. The disease is characterized by relapses and the symptoms and course are highly variable. The diagnosis is primarily clinical and supported by results of diagnostic studies. The importance of timely diagnosis has increased with the availability of effective treatment. The purpose of this article is to review symptoms, signs, diagnosis and treatment of multiple sclerosis.
