Repeated magnetic resonance imaging and cerebral performance after cardiac arrest--a pilot study.

Resuscitation 2011 May 1;82(5):549-55. Epub 2011 Mar 1.

Department of Anaesthesia and Intensive Care, Haukeland University Hospital, Bergen, Norway.

Aim Of The Study: Prognostication may be difficult in comatose cardiac arrest survivors. Magnetic resonance imaging (MRI) is potentially useful in the prediction of neurological outcome, and it may detect acute ischemia at an early stage. In a pilot setting we determined the prevalence and development of cerebral ischemia using serial MRI examinations and neurological assessment.

Methods: Ten witnessed out-of-hospital cardiac arrest patients were included. MRI was carried out approximately 2h after admission to the hospital, repeated after 24h of therapeutic hypothermia and 96 h after the arrest. The images were assessed for development of acute ischemic lesions. Neurophysiological and cognitive tests as well as a self-reported quality-of-life questionnaire, Short Form-36 (SF-36), were administered minimum 12 months after discharge.

Results: None of the patients had acute cerebral ischemia on MRI at admission. Three patients developed ischemic lesions after therapeutic hypothermia. There was a change in the apparent diffusion coefficient, which significantly correlated with the temperature (p < 0.001). The neurophysiological tests appeared normal. The patients scored significantly better on SF 36 than the controls as regards both bodily pain (p = 0.023) and mental health (p = 0.016).

Conclusions: MRI performed in an early phase after cardiac arrest has limitations, as MRI performed after 24 and 96 h revealed ischemic lesions not detectable on admission. ADC was related to the core temperature, and not to the volume distributed intravenously. Follow-up neurophysiologic tests and self-reported quality of life were good.

Comorbidity in restless legs syndrome among a sample of Swedish adults.

Sleep Med 2007 Nov 6;8(7-8):768-72. Epub 2007 Sep 6.

Sleep Disorders Center, Avesta Hospital, SE-774-82 Avesta, Sweden.

Background: Restless legs syndrome (RLS) is a neurological movement disorder, which often causes sleep problems. However, the comorbidity of this disorder is not well known. This study aimed to document the prevalence of RLS in the general population of Sweden and to identify factors associated with this condition.

Methods: A cross-sectional study was performed in Sweden. One thousand subjects aged 18-90 years old underwent telephone interviews. The questionnaire assessed such factors as sleep variables, depressive mood, treatment of diabetes mellitus, and treatment with drugs for depression during the previous four-week period. RLS was diagnosed based on the minimal criteria provided by the International RLS Study Group.

Results: The prevalence of RLS was 5% (5.7% in women, 3.5% in men). Severe or very severe RLS symptoms during the previous week were noted by 64% of the RLS subjects. Factors associated with RLS were insomnia, excessive daytime sleepiness, periodic limb movements in sleep, and depressed mood. Those affected by RLS were not more often consumers of drugs for depression than non-RLS subjects.

Conclusions: RLS is prevalent in the general population in Sweden. RLS negatively influenced sleep and was associated with depressed mood. Antidepressive drug treatment was not associated with RLS.

Prevalence, severity and risk factors of restless legs syndrome in the general adult population in two Scandinavian countries.

Sleep Med 2005 Jul;6(4):307-12

Department of Public Health and Primary Health Care, University of Bergen, Kalfarveien 31 N-5018, Bergen, Norway.

Background And Purpose: To estimate prevalence and severity (using the International Restless Legs Syndrome Study Group Rating Scale (IRLS)) and to identify risk factors of restless legs syndrome (RLS).

Patients And Methods: Population-based cross-sectional study; 2005 randomly selected adults 18 years and above participated in a telephone interview in Norway and Denmark, employing the next-birthday technique.

Results: Of the cross-section, 11.5% fulfilled the diagnostic criteria for RLS. Half of these reported the symptoms as moderate to very severe. Mean duration of the complaint was 10 years. Prevalence was higher in females than in males (13.4 vs 9.4%) and lowest in the youngest age group (18-29 years, 6.3%). From 30 years and above, no clear age-related difference was seen. Main predictors of RLS were insomnia (odds ratios: 1.71-3.16) and symptoms of periodic limb movements in sleep (3.20-7.85). The response rate was 47%, making the results less reliable.

Conclusions: This study indicates that there is a high occurrence of RLS among adults. Main predictors are insomnia and periodic limb movements in sleep.

[Neurologic decompression sickness in sports divers].

Tidsskr Nor Laegeforen 2002 Jun;122(17):1649-51

Nevrologisk avdeling, Haukeland Sykehus 5021 Bergen.

Background: Sports diving is a popular recreational activity. Sports divers presenting with acute decompression sickness may exhibit residual neurologic and neuropsychological symptoms during follow-up, in spite of appropriate treatment.

Material And Methods: A retrospective review of medical records was carried out for sports divers admitted to the department of neurology at Haukeland University Hospital during 1997.

Results: 11 out of 20 divers experienced residual neurological symptoms after treatment. Five responded poorly to treatment, with 50% or more residual clinical score. These patients tended to be older, had performed deeper dives, and more repetitive diving. Seven divers had increased slow wave activity in EEG on initial recording, in two the EEG changes persisted after treatment.

Interpretation: In this small series of sports divers with decompression sickness and arterial gas embolism, most neurologic symptoms responded to hyperbaric treatment. However, more than one half of the divers had residual neurological symptoms on discharge. Sensory loss and asymmetrical reflexes were the most common residual findings.

[Spasticity treated with selective posterior rhizotomy].

Tidsskr Nor Laegeforen 2002 May;122(12):1190-1

Nevrologisk avdeling, Haukeland Sykehus 5021 Bergen.

Background: Spasticity is often seen in patients with central nervous lesions. Some patients with severe spasticity are not optimally treated with physiotherapy and medication.

Material And Methods: We present a case history of a 41-year-old woman with multiple sclerosis and severe painful spasticity in her lower limbs. Her spasticity did not respond to treatment with physiotherapy, spasmolytic medication, botulinum toxin A, intrathecal baclofen or epidural spinal cord stimulation.

Result: The patient was treated with selective posterior rhizotomy S1-L1. Section of 60% of the rootlets on the right side and 40% on left the side resulted in a good outcome with less spasticity and pain. Finally her contractures were treated with tenotomy and myotomy, also with good functional result.

Interpretation: Patients suffering from severe painful spasticity and who do not respond to physiotherapy in combination with other spasmolytic medication should be considered for surgical treatment. In some patients posterior rhizotomy is the treatment of choice.
