- Objectives To present hearing results after successful primary myringoplasty surgeries registered in the Swedish Quality Registry for Myringoplasty and to evaluate the chance of hearing improvement and the risk of hearing loss. Design A retrospective nationwide cohort study based on prospectively collected registry data between 2002 and 2012. Settings Registry data from secondary and tertiary hospitals performing myringoplasty. Participants Patients with healed tympanic membrane after primary myringoplasty surgery performed from 2002 to 2012 in Sweden. Main outcome measures Postoperative hearing results, hearing gain and air-bone gap (ABG). Results In 2226 myringoplasties, air conduction audiograms were recorded, and the average preoperative pure tone average (PTA(4)) of the group was 28.5 dB, which improved postoperatively to 19.6 dB with an average of 8.8 dB improvement. Bone conduction was measured for 1476 procedures. Closure of the ABG to 10 dB or less was achieved in 51% of the ears and to less than 20 dB in 89% of the ears. Sixty-one percent of patients with preoperatively deteriorated hearing experienced improved hearing, but 3% of all patients experienced deteriorated hearing. After the surgery, 93% of the patients were satisfied. Conclusions Hearing results after successful myringoplasty surgery are often favourable, but although the tympanic membrane is healed, hearing improvement is not guaranteed, and hearing deterioration can also occur.

Molecular Characterization of Diffuse Large B-cell Lymphoma and Aspects of Transformation
- 2004

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Lymphomas are a heterogeneous group of neoplasias originating from B- or T-lymphocytes. In this thesis, we determined the genetic and immunophenotypic characterization of DLBCL and their prognostic impact. Moreover, genomic alterations associated with the transformation to DLBCL from Hodgkin lymphoma (HL) and follicular lymphoma (FL) were elucidated. In order to outline the impact of cytogenetic as well as immunophenotypic prognostic markers in DLBCL, we firstly studied a series of 54 DLBCL tumors using comparative genomic hybridization (CGH) and we identified several frequently occurring chromosomal imbalances. Loss of 22q was more often found in the diagnostic tumors with a more advanced clinical stage, while gain of 18q21 was more commonly identified in relapses. Secondly, we correlated the expression patterns of CD10, bcl-6, IRF-4 and bcl-2 with clinical parameters in a series of 173 de novo DLBCL patients. Patients with a germinal center (GC) phenotype displayed a better survival than the non-GC group. Expression of bcl-6 and CD10 was correlated with a better survival while bcl-2 expression was associated with a poor prognosis.In approaching the HL transformation, two novel B-cell lines (U-2932 and U-2940), derived from patients with DLBCL following HL, were characterized. Interestingly, a translocation with materials from 2q and 7q as well as loss of material on 6q was found in both cell lines. For FL transformation, we assessed chromosomal alterations in a panel of 28 DLBCL patients with a previous history of FL. The DLBCL tumors displayed more chromosomal imbalances compared to FL tumors. Loss of 6q16-21 and gain of 7pter-q22 were more commonly found in the DLBCL counterparts, suggesting the chromosomal location of putative genes that may be involved in the transformation process.

- OBJECTIVES/HYPOTHESIS: Data from patients registered for myringoplasty during 2002 to 2012 in the Swedish National Quality Registry for Myringoplasty.STUDY DESIGN: Both conventional myringoplasty and fat-graft techniques were used aimed at healing the tympanic membrane in noninfected ears.METHODS: Analysis was performed on data in a national database collected from 32 ear, nose, and throat clinics. Surgical procedures and outcomes, and patient satisfaction from a questionnaire were studied.RESULTS: The database was comprised of 3,775 surgical procedures, with follow-up available for analysis. One-third were children under the age of 15 years. The most common indication for surgery was infection prophylaxis. The overall healing rate of the tympanic membrane after surgery was 88.5%, with a high mean patient satisfaction. Complications registered were postoperative infection, tinnitus, or taste disturbance that occurred in 5.8% of patients.CONCLUSIONS: Swedish results for a large number of patients who completed myringoplasty are presented. The success rate in this study is comparable to other studies, and good patient-reported outcome measures of myringoplasty are presented. Databases for surgical procedures and clinical audits are systematic processes for continuous learning in healthcare. This study shows that clinical databases can be utilized to analyze national results of surgical procedures.LEVEL OF EVIDENCE: 2b Laryngoscope, 127:2389-2395, 2017.

- This qualitative study describes how reflection can be supported by using reflective tools in group education in type 2 diabetes. The changed conditions for living with a long-term illness may lead to increased anxiety and new demands that affect one’s current life situation. The didactic model, ‘The challenge – to take charge of one’s life with long-term illness’, has been developed into ‘Taking responsibility in life with type 2 diabetes – a model for group education in primary care’. Specialized diabetes nurses and dieticians received training, a manual and continuous guidance in applying the model. Reflection diaries, notes and interviews both from the patients and the caregivers were analyzed using a phenomenological hermeneutic method. The results show that using images as reflective tools engages thoughts and feelings in a way that appears to be important for one’s learning in life with a chronic illness. The images contribute to allowing a distance from one’s situation, actions, thoughts and feelings, which seems fruitful for investigating and discovering new ‘things’ about oneself. With the support of reflective tools and guiding questions, reflection is led to a deeper existential level where both caregivers and patients contribute by asking questions that support the reflection process.

- Aims: To investigate the prognostic value of cyclin E in relation to tumour growth pattern by analysing stage II primary breast cancers from premenopausal women not subjected to any further adjuvant treatment. To analyse the value of cyclin E as a predictor of tamoxifen response, by comparing untreated and treated patients with oestrogen receptor positive tumours. Methods: Breast cancer samples, assembled in tissue microarrays, were immunohistochemically stained for cyclin E and evaluated regarding the presence of nuclear staining. The overall growth characteristics of each tumour were assessed using whole tissue sections. Results: Tumours displaying a pushing margin phenotype were strongly associated with high cyclin E levels, lymph node negative disease, a high histological grade and oestrogen receptor negativity, and exhibited a better prognosis compared to tumours with an infiltrative growth pattern. In the total cohort of non-treated patients (n = 187), cyclin E was not associated with recurrence free survival (RFS). However, when analysing the subgroup of tumours lacking a pushing growth pattern (n = 141), cyclin E was significantly associated with RFS, independent of histological grade and node status. There was no significant difference in tamoxifen response with regard to different cyclin E levels. Conclusion: The prognostic value of cyclin E in premenopausal breast cancer is limited to patients with breast carcinomas exhibiting an exclusively infiltrative growth pattern. This limitation could be explained by the presence of a small but distinct subgroup of cyclin E-high breast cancers with a pushing margin phenotype and a more favourable outcome.

- OBJECTIVE: The aim of this study was to investigate whether homocysteine is linked to atherothrombotic (AT) events in patients with rheumatoid arthritis (RA). METHODS: Analysis of homocysteine (Hcy) levels was carried out in 235 consecutive RA patients. They were followed-up for 6.5 years or until death, with analysis of AT risk factors and the type and length of DMARD and corticosteroid treatment. The disease history before inclusion was collected. Six categories of AT events were defined. In addition, the diagnosis of the patients at follow-up was co-analyzed with the nationwide population-based Swedish Inpatient Register and Death Register to certify all events. RESULTS: The Hcy level was found to be higher in males (p<0.05) and increased with age (p<0.001). Patients with folic acid supplementation had significantly lower levels, while those on corticosteroids had higher levels. High Hcy levels predicted AT events (n=48) during a 6.5-year follow-up adjusted for age and male sex in a logistic regression analysis. CONCLUSION: In this study, RA patients on folic acid had lower Hcy levels. High Hcy levels (in addition to age, sex and diabetes) predicted AT event prospectively.
