RESUMEN
PURPOSE: The Sino-Nasal Outcome Test-22 (SNOT-22) is the most commonly used disease-specific quality of life questionnaire in rhinology. The purpose of this prospective study was to translate and validate SNOT-22 into Finnish. METHODS: The validation process followed the guidelines proposed for cross-cultural adaptation of health-related measures of quality of life. The study consisted of three groups: rhinologic out-patients (N = 96), FESS patients (N = 49) and healthy controls (N = 79). Out-patient and FESS groups completed the questionnaire twice (answers A and B), out-patients after two weeks and FESS patients after 3 months. Validity, reliability and responsiveness were evaluated. RESULTS: The mean SNOT-22 sum score of the out-patient questionnaires were 35.3 points (answer A) and 32.4 points (answer B). ICC in out-patient group was 0.879. For the FESS patients, the mean pre- and postoperative (answer A and B) SNOT-22 sum scores were 46.8 and 21.9 points, respectively (p < 0.0001). The mean SNOT-22 of healthy controls was 8.9 points. The out-patients (answer A) and healthy controls had statistically significant difference in SNOT-22 scores (p < 0.0001). CONCLUSIONS: The results of our study show that the validated Finnish version of the SNOT-22 questionnaire demonstrates good validity, reliability and responsiveness.

PURPOSE: To explore factors related to pathogenesis of rhegmatogenous retinal detachment (RRD) and development of proliferative vitreoretinopathy (PVR), vitreous levels of angiopoietin-1 and -2 (Ang-1 and -2), previously undefined in RRD, transforming growth factor-(TGF) ß1, vascular endothelial growth factor (VEGF), erythropoietin (EPO) and proteolytic mediators of extracellular matrix remodelling (MMP-2 and -9) were compared in eyes with RRD and eyes with idiopathic macular hole or pucker. METHODS: Vitreous samples were collected from 117 eyes with RRD (study group) and 40 eyes with macular hole or pucker (control group). Growth factors were measured by ELISA and matrix metalloproteinases (MMPs) by gelatin zymography. RESULTS: The mean vitreous concentrations of Ang-2, MMP-2, and MMP-9 were higher (all p < 0.01), whereas concentration of VEGF was lower (p = 0.01) in eyes with RRD relative to controls. Logistic regression analysis identified Ang-2 concentration as a novel marker of RRD (p = 0.0001, OR 48.7). Ang-1, EPO, and total TGF-ß1 levels were not significantly different between the groups. However, TGF-ß1 and MMP-2 were increased in eyes with total RRD compared to those with local RRD (p ≤ 0.05). In eyes with PVR, no differences were observed in any studied marker as compared with non-PVR eyes. CONCLUSIONS: Current results reveal Ang-2 as a key factor upregulated in RRD. It may co-operate with fibrosis-associated factors and contribute to vascular complications such as breakdown of blood-eye barrier and PVR development.

Articulatory proficiency of /r/ and /s/ sounds, voice quality and resonance, speech intelligibility, and intraoral sensation were examined prospectively before operation, and at four time points during a 1-year follow-up after microvascular transfer. Forty-one patients with a large oral or oropharyngeal carcinoma undergoing tumor resection and free-flap reconstruction usually combined with radiotherapy participated in the study. Articulation, voice, and resonance were investigated both live and from recorded speech samples by two trained linguistic examiners. The patients completed a self-rating of their speech intelligibility and were assessed for anterior intraoral surface sensation by means of 2-point moving discrimination. Misarticulations of /r/ and /s/ increased significantly after the therapy. Voice quality and resonance remained essentially normal. Speech intelligibility deteriorated significantly. Intraoral sensation decreased postoperatively but was not related to speech outcome. Sensate flaps did not prove to be superior in relation to speech tasks. A multidisciplinary approach is advocated in assessment of speech outcome after cancer surgery. Speech therapy is strongly recommended, even in the absence of a gross articulatory handicap.

Swallowing and intraoral sensation outcome were investigated prospectively after microvascular free-flap reconstruction. Forty-one patients with a large oral or oropharyngeal carcinoma underwent free-flap surgery usually combined with radiotherapy. The patients completed modified barium swallow, self-rating of swallowing, and 2-point moving discrimination preoperatively and at four time points during the 12-month follow-up period, and a plain chest X-ray one year after operation. Swallowing was impaired with respect to an objective and subjective measure after therapy. Rates for nonsilent and silent aspiration increased during the follow-up. Intraoral sensation deteriorated. Swallowing outcome was not related to sensation. One year after surgery, 86% of the patients ate regular masticated or soft food. Microvascular transfers offer a reasonable option for oral reconstruction. This study does not support the need for sensate flaps. Swallowing problems should be routinely sought and patients rehabilitated during a sufficiently long follow-up with videofluorography regardless of the patient's perception of swallowing.

PURPOSE: Angiogenesis in diabetic retinopathy (DR) is a multifactorial process regulated by hypoxia-induced growth factors and inflammatory cytokines. In addition to the angiogenic switch, the proteolytic processing and altered synthesis of the extracellular matrix are critical steps in this disease. This study was performed to evaluate the levels of matrix metalloproteinase-2 and matrix metalloproteinase-9 (MMP-2 and MMP-9), angiopoietin-1 and angiopoietin-2 (Ang-1 and Ang-2), vascular endothelial growth factor (VEGF), erythropoietin (EPO) and transforming growth factor-ß1 (totalTGFß1) in the vitreous of diabetic eyes undergoing vitrectomy compared with control eyes operated because of macular hole or pucker. METHODS: Prospective consecutive controlled observational study performed in the unit of vitreoretinal surgery in Finland during the years 2006-2008. Vitreous samples were collected before the start of the conventional 3-ppp vitrectomy. Vitreous MMP-2 and MMP-9, Ang-1 and Ang-2, VEGF, EPO and TGFß1 concentrations were measured from 69 patients with Type 1 or 2 diabetes and 40 controls. RESULTS: Comparison of eyes with DR with controls revealed that the mean vitreous concentrations of proMMP-2 (p = 0.0015), totalMMP-2 (p = 0.0011), proMMP-9 (p = 0.00001), totalMMP-9 (p < 0.00001), Ang-2 (p < 0.00001), VEGF (p < 0.00001), EPO (p < 0.00001) and totalTGFß1 (p = 0.000026) were significantly higher in the former group. A multivariate logistic regression analysis suggested intravitreal Ang-2 concentration being the key marker of PDR (p = 0.00025) (OR = 1507.9). CONCLUSION: The main new finding is that the intravitreal concentrations of Ang-2 correlated significantly with MMP-9, VEGF, EPO and TGFß1 levels in diabetic eyes undergoing vitrectomy. Thus, these factors could promote retinal angiogenesis synergistically.
