  • Plasma oxytocin and personality traits in psychiatric outpatients
  • 2015
  • Ingår i: Psychoneuroendocrinology. - 0306-4530. ; 57, s. 102-110
  • Tidskriftsartikel (refereegranskat)abstract
    • The oxytocin system is regarded as being of relevance for social interaction. In spite of this, very few studies have investigated the relationship between oxytocin and personality traits in clinical psychiatric populations. We assessed the relationship between personality traits and plasma oxytocin levels in a population of 101 medication-free psychiatric outpatients (men = 37, women = 64). We used the Karolinska Scale of Personality (KSP) and diagnostic and symptomatic testing. Plasma oxytocin levels were analysed with a specific radioimmunoassay at inclusion and after one month for testing of stability. Plasma oxytocin levels were stable over time and did not differ between patients with or without personality disorders, nor were they related to severity of depressive or anxiety symptoms. The KSP factors Impulsiveness and Negative Emotionality were significant independent predictors of plasma oxytocin. A subscale analysis of these personality factors showed significant positive correlations between baseline plasma oxytocin and the KSP subscales monotony avoidance and psychic anxiety. The significant association between the KSP factor Impulsiveness and oxytocin levels observed at baseline was observed also one month later in men. These findings suggest that personality traits such as Impulsiveness and Negative emotionality which are linked to social functioning in several psychiatric disorders seem to be associated with endogenous plasma oxytocin levels. These variations in oxytocin levels might have an impact on social sensitivity or social motivation with possible gender differences.

  • Client perceptions of the Tree Theme Method: a structured intervention based on storytelling and creative activities.
  • 2010
  • Ingår i: Scandinavian Journal of Occupational Therapy. - Taylor & Francis. - 1651-2014. ; 17:3, s. 200-208
  • Tidskriftsartikel (refereegranskat)abstract
    • The Tree Theme Method (TTM) is an intervention based on sessions involving creative activities and life storytelling/story-making, in which the client paints trees representing various periods of his/her life. The aim of this study was to investigate clients' experiences of participating in a TTM intervention and their perceptions of the therapeutic relationship. Thematic interviews were undertaken. Twenty clients attending general outpatient mental healthcare units were recruited after having participated in the intervention. A qualitative content analysis resulted in six categories: "From feeling a pressure to perform to becoming focused and expressive", "Expressing oneself and one's life situation led to awakening of memories and feelings", "New perspectives of self-image, everyday life and relations to others", "Story-making led to shaping and reconstructing one's life story", "Interaction was of importance when reconstructing one's life story" and, finally, "The attitude of the occupational therapist was of importance for the development of the therapeutic relationship". There seemed to be a close association between the intervention and the therapeutic relationship in starting a process of opening up new perspectives on everyday life, but there is a need for further studies including therapists' experience of using the TTM and their perception of the client-therapist relationship.

    • Aim: To determine if the use of alcohol-based hand-disinfection as a complement to regular hand washing at daycare centers (DCCs) can reduce the childhood rate of absenteeism. Methods: Children aged 0-6 years attending DCC were studied in a cluster randomized controlled trial during 30 weeks. Thirty matched pairs of DCCs were included in the study, where one of the DCCs was randomized to intervention and the other to control within each pair. The intervention consisted in children and staff using alcohol-based oily disinfectant gel containing 70% ethanol after regular hand washing. The main outcome was the rate of episodes of absence from DCC due to infection. A regression model was fitted at the individual level and controlling several possible confounders for illness. Absences were reported by the parents. Results: Differences in missing absence reports between the two groups led to only evaluating those 29 DCCs (1431 children) that were able to provide complete reports. In the multivariate regression, the intervention significantly reduced the rate of absenteeism of a child by 12% compared to a child in a control DCC (IRR 95% CI: 0.799-0.965). Conclusion: Hand-disinfection used by children and staff significantly decreased childrens absences due to infections in Swedish DCCs.

  • Ett kvartssekel med föräldragrupper i barnhälsovården - var står vi idag?
  • 2005
  • Ingår i: Läkartidningen. - Swedish Medical Association. - 0023-7205. ; 102:39, s. 6-2754
  • Tidskriftsartikel (refereegranskat)abstract
    • En trygg föräldrarelation, präglad av värme och rimliga gränser, är en viktig förutsättning för barns hälsa och välfärd och för att de senare i livet ska kunna samspela förtroendefullt med omgivningen. Inom hälso- och sjukvården finns idag en omfattande verksamhet, exempelvis öppna föräldragrupper, vars syfte är att ge stöd i föräldraskapet. En aktuell rapport från Folkhälsoinstitutet visar att en stor del av denna verksamhet fortfarande saknar vetenskaplig evidens, men också att tillgången på evidens ökat dramatiskt under de senaste 10–15 åren. Här redovisas resultaten från tre lokala studier av föräldragrupper inom barnhälsovården, vilka exemplifierar resultaten i Folkhälsoinstitutets rapport.

  • What is good parental education?
  • 2004
  • Ingår i: Scandinavian Journal of Caring Sciences. - Wiley-Blackwell. - 1471-6712. ; 18:1, s. 82-89
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the study was to highlight the experiences and expectations of Swedish parents with respect to general parental education within child healthcare. Interviews were carried out with 25 parents who had attended education sessions. With a few exceptions the fathers did not take part, and those mothers who did comprised a relatively highly educated group; their views therefore predominate in this study. Socially vulnerable parents such as the unemployed and immigrants took part more sporadically in the meetings, which is why less material is available from these groups. The arrangement and analysis of the material was done using qualitative content analysis. We identified two main categories of importance: 'parental education content' and 'parental education structure'. The parents were on the whole satisfied with the content with respect to the child's physical and psychosocial development. On the other hand, first-time parents expressed a degree of uncertainty with respect to the new parent roles and parent relation and they thought that the education should place more emphasis on the interplay between the parents and between child and parents. The degree of confidence in the nurse as group leader was mainly high. The parents thought that the groups functioned well socially and were satisfied with the organization of the meetings. They did, however, demand clearer structure and framework with respect to the content. Since the aim of legally established parental education is to improve the conditions of childhood growth and to provide support to parents, it must be considered especially important to provide resources so that the socially vulnerable groups in the community may also be reached.

  • Prolyl-leucyl-glycinamide shares some effects with oxytocin but decreases oxytocin levels
  • 2004
  • Ingår i: Physiology & Behavior. - 0031-9384 .- 1873-507X. ; 83:3, s. 475-481

    • Oxytocin treatment in rats induces long-lasting antistress and growth promoting effects. This study investigated whether prolyl-leucyl-glycinamide (PLG) (the c-terminal tripeptide of oxytocin) or tocinoic acid (the ring structure of oxytocin) could induce some of these effects in male rats. For this purpose, PLG (2 or 10 mg/kg, s. c.) or tocinoic acid (1 mg/kg, s. c.) was administered to rats once a day for 3 or 5 days. Blood pressure, heart rate, spontaneous motor activity, nociceptive thresholds, and the survival of ischaemic musculocutaneous flaps were measured. In addition, endogenous oxytocin levels and plasma levels of some hormones known to be influenced by oxytocin were determined. PLG (2 mg/kg, s.c., but not 10 mg/kg, s.c.) decreased diastolic blood pressure (p<0.05) and locomotor activity (p<0.05). PLG (10 mg/kg, s.c.) decreased gastrin (p<0.05) and endogenous oxytocin levels in plasma (p<0.01). Tocinoic acid decreased locomotor activity (p<0.05), but did not affect any of the other parameters measured. In conclusion, this study showed that both PLG and tocinoic acid decrease locomotor activity. In addition, PLG also induced some other effects similar to those induced by oxytocin treatment but when administered in high doses it decreased oxytocin levels. (C) 2004 Elsevier Inc.

    • Aim: Atypical odontalgia(AO) is a chronic pain condition located in the teeth and jaws. It has been suggested, that AO is best regarded as a neuropathic pain condition, but knowledge regarding the etiology, diagnostics, and management of AO is not yet satisfactory. This pilot study evaluates the clinical usefulness of more recently developed imaging methods for intraoral pain conditions. The aim is to compare the diagnostic findings using magnetic resonance imaging(MRI) and cone beam computed tomography(CBCT) with the findings from conventional radiography in patients with atypical odontalgia(AO) and symptomatic apical periodontitis(SAP). Material and methods: 12 patients (9 F, 3 M) mean age 50,25 years, range 36 - 63 years participated in the study. The patients were referred to the Orofacial Pain Unit or the Department of Endodontics, Faculty of Odontology, Malmö University. Inclusion criteria for AO were chronic pain (>6 months) located in a region where a tooth had been endodontically or surgically treated, pain with no pathological cause detectable in clinical or radiological examinations. For SAP, the inclusion criteria were recurrent pain from a tooth diagnosed with apical periodontitis in a clinical and radiographic examination. Ten of the patients in the study were diagnosed with AO and two with SAP. The patients were clinically assessed with a qualitative somatosensory examination, a dental examination, an examination of the masticatory system(RDC/TMD), and panoramic and intraoral radiographs. A questionnaire was used to gather information about pain characteristics, psychosocial status(SCL-90), and quality of life. Besides these measures, each patient underwent a CBCT(3D-Accuitomo, J Morita Co) examination and a MRI(Siemens Sonata Vision 1.5 T) examination with and without contrast enhancement. Contrast was enhanced by injections of Magnevist (469 mg/ml, Schering Nordiska). Bone destruction, sclerosis, and signs of inflammation were the main parameters studied. Results: In the preliminary results, average pain intensity was 6.3 on a numerical rating scale(NRS) and average pain duration was 3,6 years. 83% exhibited somatosensory abnormalities. Bone destruction not visible in the intraoral and panoramic radiographs was detected with CBCT in 40% (4/10) of the patients diagnosed with AO, and signs of inflammation were detected in the MRIs of 20% (2/10) of the patients diagnosed with AO. Conclusion: Preliminary findings indicate that CBCT and MRI can provide additional information to conventional radiography in the diagnosis of intraoral orofacial pain. Further studies with larger sample sizes of AO and SAP patients are necessary to determine the clinical relevance of these findings.

  • Diagnostic yield of conventional radiographic and cone-beem computed tomographic images in patients with atypical odontalgia
  • 2011

    • Abstract AIM: To investigate whether the additional diagnostic yield of a cone-beam computed tomography (CBCT) examination over conventional radiographs in patients primarily suspected of having atypical odontalgia (AO) improves differentiation between AO and symptomatic apical periodontitis (SAP) in patients with severe chronic intraoral pain. METHODOLOGY: In this clinical study, 25 patients (mean age 54 ± 11 years, range 34-72) participated; 20 were diagnosed with AO and 5 with SAP. All patients were recruited from the clinics of the Faculty of Odontology, Malmö University. AO inclusion criteria were chronic pain (>6 months) in a region where a tooth had been endodontically or surgically treated, with no pathological cause detectable in clinical or radiologic examinations. SAP inclusion criteria were recurrent pain from a tooth diagnosed with apical periodontitis in clinical and radiographic examinations. Assessments comprised a self-report questionnaire on pain characteristics, a comprehensive clinical examination and a radiographic examination including panoramic and intraoral radiographs and CBCT images. The main outcome measure was periapical bone destruction. RESULTS: Sixty per cent of patients with AO had no periapical bone destructions detectable with any radiographic method. Overall, CBCT rendered 17% more periapical bone destructions than conventional radiography. Average pain intensity in patients with AO was 5.6 (± 1.8) on a 0-10 numerical rating scale, and average pain duration was 4.3 (± 5.2) years. CONCLUSION: Cone-beam computed tomography improves identification of patients without periapical bone destruction, which may facilitate differentiation between AO and SAP.
