- The aim of this cohort study was to evaluate the stability after multi-segmentation of the maxilla for correction of anterior open bite deformities. A total of 33 patients who underwent segmented maxillary osteotomy between 1994 and 2006 were included in the study. Rigid fixation with plates and postsurgical intermaxillary fixation for 6 weeks was applied to each patient. All patients were then followed in a standardized examination procedure at months 6, 12, 18 and up to 30 months postoperatively. Vertical and horizontal relation of the incisors was measured both clinically and on cast models. The main finding was that statistically significant relapse was found vertically, whereas the horizontal relationship to the mandible was unchanged. The vertical relapses were predominantly seen in patients with severe open bite evident preoperatively.

Konferensbidrag (refereegranskat)abstract
- We use a 3.3 µm high-power continuous wave pump and a 1.67 µm comb probe to detect transitions in the 3ν3 ← ν3 range of methane with sub-Doppler resolution over 6 THz of bandwidth. We achieve high absorption sensitivity for the comb probe using an enhancement cavity and a Fourier transform spectrometer with auto-balanced detection.

Nedfall och avrinning av metaller, svavel och kväve i närheten av Rönnskärsverken från 1986/87 - 2020/21 : Årsrapport 2022
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I denna rapport redovisas mätresulaten från det hydrologiska året 2020/21 vad gäller metaller, svavel och kväve i deposition och avrinning i närheten av Boliden Mineral AB:s smältverk vid Rönnskär. I rapporten redovisas även jämförelser med tidigare års resultat, sedan mitten av 1980-talet, för svavel och kväve vid andra relevanta lokaler med liknande mätningar inom Krondroppsnätet i norra Sverige samt för metaller vid bakgrundsstationer inom nationell miljöövervakning. Depositionen vid Holmsvattnet jämförs också med emissioner av vissa metaller från Rönnskärsverken, Sverige och EU27 + UK.

Tidskriftsartikel (refereegranskat)abstract
- Aim: Surgical corrections of dentofacial deformities have both physical and psychological impact on quality of life (QoL). The objectives of the present study were to evaluate the impact of oral health related problems on QoL before and after a combination of orthodontic treatment and orthognathic surgery. Additionally, the study aimed to identify correlations between different dentofacial patterns and possible improvements due to treatment. Material and methods: In a prospective study, we evaluated fifty patients before start of treatment, 6 weeks and 6 months postoperatively. The questionnaires used were: OHIP-14 (Short Form Oral Health Impact Profile), a condition-specific QOL approach (Orthognathic Quality of Life Questionnaires; OQLQ) and a social-demographic questionnaire. Results: There was a statistically significant improvement in the OHIP domains from baseline to 6 months follow-up and for the OQLQ the improvement was significant both at 6 weeks and 6 months in relation to the baseline data. Conclusion: Significant improvement of quality of life over time is proved by both OHIP-14 and OQLQ in the present study. Socio-demographic and holistic considerations are important when evaluating treatment outcome after combined orthodontic and orthognatic surgery. However, longer follow-up would be beneficial.

Human papillomavirus and cervical carcinoma in situ : implications for future screening
- 2000
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The principal aim of this thesis was to study the temporal relationship between human papillomavirus type 16 (HPV 16) infection and cervical carcinoma in situ, particularly focusing on the effect of viral load. Other aims were to study the role of additional factors, especially smoking and oral contraceptive use, in cervical carcinogenesis. We conducted a case-control study, nested within a population-based cohort of women participating in cytological screening in Uppsala county in Sweden during 1969 to 1995. All incident cases of cervical carcinoma in situ during this period were identified. For each case, one or two controls, matched by age and date of entry to the cohort, were selected randomly from the cohort. A sensitive PCR assay was used to detect and quantitate HPV 16 load in repeatedly taken smears during Lip to 26 years before diagnosis in cases and their matched controls. Altogether 2553 archival smears from 495 cases and 2164 smears from 649 controls were tested. In addition, detailed information on sexual practice, smoking habits and oral contraceptive use were collected through telephone interviews with 422 cases and 422 controls. We developed a single-tube nested PCR-based system for detection of 19 different genital HPV types in archival smears. Our detection system had a high sensitivity, comparable to the most commonly used PCR-based HPV typing systems. We found an age-dependent increased risk of cervical carcinoma in situ in relation to current smoking, especially confined to women younger than 45 years. An increased risk was further demonstrated with increasing tobacco consumption (duration, intensity, pack-years). Current use of oral contraceptives was positively associated with the risk of cervical carcinoma in situ, with a monotonic increase in risk with increasing duration of use. The number of sexual partners was significantly, positively associated with risk among HPV 16/18-negative but not among HPV 16/18-positive women. We failed to demonstrate any increased risk in relation to age at first intercourse or parity. The prevalence of HPV 16 positivity among cases was 56% at the time of diagnosis. Having an HPV 16-positive smear at entry to the cohort was associated with a moderately increased risk, whereas having persistent infection with HPV 16 in two subsequent smears was strongly associated with risk of cervical carcinoma in situ. We estimated that among HPV 16-positive women the median incubation period from first detected HPV infection to cervical carcinoma in situ was between 7 and 12 years. Among cases, we found a consistently increased load of HPV 16, detected already 13 years before diagnosis, and often when the smear was still cytologically normal. Women with a high load of HPV 16, were at an over thirty-fold relative risk compared to HPV 16-negative women more than a decade prior to diagnosis. Women with the 20% highest viral load in their first smear, taken on average 7.8 years before diagnosis, had a sixty times higher risk compared to women negative for HPV in their first smear. We further estimated that approximately 114 of women infected with a high viral load before age 25 years, developed cervical carcinoma in situ within 15 years.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Young people in low and middle income countries (LMICs) in societal transitions with rapidly changing norms face an increased risk of suicide. This study explores how young people in Cambodia understand the impact on suicidal behaviour from societal attitudes, media and religion.MATERIAL: Focus group discussions were held with school students from a suburban area. Thematic analysis was used to interpret the data.DISCUSSION: Participants perceived the prevailing suicide-stigmatizing societal attitudes, the double-edged media and suicide-ambiguity in Buddhist religion as challenging. Globalization was recognized as contradicting with traditional Cambodian norms and values.CONCLUSION: Suicide prevention programmes should take into consideration the complex picture of suicide that young people are exposed to.
