- Fourteen adult Fischer 344 rats were inoculated in vivo unilaterally in the caudate nucleus in the brain with malignant RG 2 glioma cells. By 3 weeks a tumor with a diameter of 3-6 mm normally develops. Ten animals which survived the repeated periods of anesthesia and thallium (Tl) injections (intratumorally three times of 201Tl, 15-23 days after inoculation) showed a prolonged retention of radioactivity at the site of injection with no uptake in other organs except for the kidneys. Singular circumscribed necroses were found post-mortem at the site of injection, comprising malignant glioma tumor tissue, which in six animals was absent, in three animals was markedly reduced in size compared with controls and in one animal had the expected size. In four animals metastases were found in distant locations in the brain; in three of these cases there was a retention of radioactivity in the tumor. The selective necrotizing effect on the tumor cells is interpreted as mainly due to emission of Auger electrons from intracellularly accumulated 201Tl, giving rise to very high energy deposition in the vicinity of the cell nucleus. The results should also have implications for the treatment of human malignant gliomas.

- This study was undertaken to investigate the prevalence of coeliac disease in children and adolescents with Turner syndrome. Eighty-seven children and adolescents with Turner syndrome were screened for IgA- antiendomysium antibodies (EMA) and IgA-antigliadin antibodies (AGA), 5% (4/87) being found to be EMA-positive, and 15% (13/87) to have AGA levels above normal. Of the 10 patients who were either AGA- or EMA-positive and further investigated with intestinal biopsy, four manifested villous atrophy (i.e. all three of the EMA-positive patients, but only one of the seven AGA- positive patients). The results suggest EMA-positivity to be a good immunological marker for use in screening for coeliac disease, and such screening to be justified in patients with Turner syndrome.

- Serotonergic receptors were classified in the isolated human uterine artery with intact endothelium, using agonists and antagonists for 5-hydroxytryptamine (5-HT) receptors. The efficacy for different agonists rated: alpha-methyl-5-HT (5-HT2) = 5-HT (non-selective) = 2-methyl-5-HT (5-HT3) >> sumatriptan (5-HT1), and the potency as: sumatriptan = 5-HT > 5-HT > alpha-methyl-5-HT > 2-methyl-5-HT. The contractile effects of 5-HT and alpha-methyl-5-HT were antagonized by the 5-HT2 receptor antagonist ketanserin and the non-selective antagonist methiothepin. The efficacy of sumatriptan was comparatively low. No interaction was encountered between 2-methyl-5-HT and MDL72222, suggesting an absence of 5-HT3 receptors. The results indicate that the contractile serotonergic receptor population in the human uterine artery mainly comprises 5-HT2 receptors, although a minor contribution of contractile 5-HT1 receptors cannot be excluded.

- The study was performed to characterize pharmacologically the contractile 5-hydroxytryptamine (5-HT) receptors in the circular smooth muscle of the isolated human umbilical artery. Effects of agonists and antagonists for different 5-HT receptor subtypes were studied in intact endothelium vessel segments. All agonists induced concentration-dependent circular smooth muscle contractions. The potency was in declining order 5-HT > alpha-methyl-5-HT > sumatriptan >/= 2-methyl-5-HT. The effects of 5-HT and alpha-methyl-5-HT were antagonized by ketanserin, as well as methiothepin. The contractile effect of sumatriptan was antagonized by methiothepin but not by ketanserin. The 5-HT3 receptor antagonist, MDL 72222, did not affect the contraction by any of the agonists, including 2-methyl-5-HT. It is concluded that the 5-HT-induced contraction in the circular smooth muscle of the human umbilical artery seems to be mediated by a mixed population of 5-HT1-like receptors and 5-HT2 receptors.

Ny mätmetod för käkmuskulaturen kan finna orsaken till tinnitus : Slutrapport Nutek 92-11904
- 1997
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Tinnitus är en åkomma som i lindrigare eller allvarligare former drabbar 17% av västvärldens befolkning. Ca 85 000 svenskar har tinnitus på invalidiserande nivå. Förutom mänskligt lidande orsakar tinnitus samhällskostnader på ca 1.5 miljard kr årligen. Orsaken är till största delen okänd.Vissa tecken tyder på ett samband mellan tinnitus och funktionsstörning i en käkmuskel. Några olika icke–invasiva metoder för mätning av muskelstörning i M Pterygoideus Lateralis har utvärderas. Två av dessa är intressanta för fortsatta studier.Termografi användes för att diagnosticera muskelstörningar på ytligt liggande muskler. Vi såg åtskilliga varma områden på ytliga käk– och nackmuskler på de patienter som hade käkledsstörningar, samt möjligen tecken på onormal värme från M Pterygoideus Lateralis. Mätförhållandena var dock ej ideala.En metod att mäta EMG med adaptiv noise cancelling provades. EMG från en ryggmuskel, stört av en “EKG–signal” från hjärtat användes. Metoden fungerade bra. Fortsatt metodutveckling på t.ex. ryggmuskler borde göras.

Impact of chronic pain on health care seeking, self care, and medication : results from a population-based Swedish study
- 1999

- STUDY OBJECTIVE: To explore individual and social factors that could predict health care utilisation and medication among people with chronic pain in an unselected population. DESIGN: A mailed survey with questions about pain and mental symptoms, disability, self care action, visits to health care providers, and medication. SETTING: General populations in two Swedish primary health care (PHC) districts. Medical care was given in a state health system. PARTICIPANTS: A random sample (from the population register) of 15% of the population aged 25-74 (n = 1806). MAIN RESULTS: Among people reporting chronic pain 45.7% (compared with 29.8 of non-chronic pain persons, p < 0.05) consulted a physician and 7.2% (compared with 1.2%, p < 0.05) a physiotherapist during three months. Primary health care was the most frequent care provider. High pain intensity, aging, depression, ethnicity, and socioeconomic level had the greatest impact on physician consultations. Alternative care, used by 5.9%, was associated with high pain intensity and self care. Use of self care was influenced by high pain intensity, regular physical activity, and ethnicity. Alternative care and self care did not imply lower use of conventional health care. Women reporting chronic pain consumed more analgesics and sedatives than corresponding men. Besides female gender, high pain intensity, insomnia, physician consultation, social network, and self care action helped to explain medication with analgesics. Use of herbal remedies and ointments correlated to self care action, visit to an alternative therapist, high pain intensity, and socioeconomic level. CONCLUSIONS: The presence of chronic pain has an impressive impact on primary health care and medication. Various therapeutic actions are common and are partly overlapping. The use of health care among people with chronic pain depends above all on pain perception and intensity of pain but is also affected by ethnicity, age, socioeconomic level, and depressive symptoms. Among people with chronic pain use of analgesics is common in contrast with other types of pain relief (acupuncture, physiotherapy) suitable for treating chronic pain symptoms.

- OBJECTIVE: To study the relations between population prevalence of chronic pain and pain-related diagnoses (musculoskeletal and headaches) in primary health care (PHC) and to examine longitudinal variations in these diagnoses. DESIGN: A population-based mailed survey to catch prevalence data and continuous computerised diagnosis registration in PHC. SETTING: General population in a well-defined Swedish PHC district. SUBJECTS: A random sample of 15% of the population aged 25-74, n = 1101. Annual visitors to district physicians at the health centre. MAIN OUTCOME MEASURES: Rates of pain-related diagnoses in PHC in relation to population prevalence of chronic pain. Comparisons of the number of individuals (annual visiting rates) with pain-related diagnoses 1987-1996. RESULTS: Population pain prevalence and pain-related diagnoses in PHC corresponded as regards the magnitude and distribution of chronic pain by age and partly by pain location. Compared to low-back and widespread pain, neck-shoulder pain and headaches were less frequent in PHC in relation to reported prevalence. From 1987 to 1996 we found an increasing number of individuals seeking primary care with pain-related diagnoses. The increase was mainly assigned to the groups of fibrositis/myalgia and headache. CONCLUSION: Pain-related diagnoses in PHC reflect partly the occurrence of self-reported chronic pain symptoms in the population. The observed increase in visits with pain-related diagnoses in the last 10 years is due to an increased number of individuals with soft-tissue rheumatism and headaches. Future studies will have to elucidate whether these findings are due to an increase in morbidity or changes in care-seeking and social conditions.

Tidskriftsartikel (refereegranskat)abstract
- Haemophilia is a rare and potentially life-threatening disease. In Sweden, with a population of approximately 8.5 million, about 350 people suffer from the more severe forms of haemophilia or von Willebrand disease. Meticulous management is important if the patients are to be spared chronic disability and serious treatment complications. The disease is lifelong and affects psychosocial aspects of life among patients and their families. With the help of a grant from the Swedish Board of Halth and Welfare, a care programme has been designed to guarantee Swedish haemophiliacs comparable and optimal care. The programme has been drawn up by representatives of the three haemophilia centres in Sweden (at University Hospital, Malmo, Sahlgrenska University Hospital, Gothenburg, and Karolinska Hospital, Stockholm) in co-operation with the World Federation of National Haemophilia Organisations. To ensure optimal individual application of the programme, individualised management strategies and patient information leaflets have been prepared.
