The objective was to examine the psychometric properties of two questionnaires in Norwegian for the self-assessment of satisfaction following cochlear implantation. The International Outcome Inventory for Hearing Aids adapted for cochlear implants (IOI-CI) and two revised subscales from the Norwegian translation of the Abbreviated Profile of Hearing Aid Benefit (APHAB) were applied. Internal consistency was tested using Cronbach's α. Testing of psychometric properties included the calculation of inter-item correlations and corrected item-total correlations. Spearman's rho was used to investigate associations. Exploratory principal component analyses with Kaiser normalisation were performed. One hundred and twenty-one patients (51 males) with cochlear implants (27–88 years, M = 59). For IOI-CI, Cronbach's α was 0.79. Corrected item-total correlations ranged from 0.29 to 0.69. The factor analysis revealed two components. For APHAB, Cronbach's α was 0.91. Two components were revealed by the factor analysis. Corrected item-total correlations for the two subscales "communication in quiet situations" and "communication in adverse situations" were 0.47–0.81 and 0.58–0.80, respectively. The convergent validity of the questionnaires was adequate as reflected by a Spearman's coefficient of 0.67. Both questionnaires show good psychometric properties. [ABSTRACT FROM AUTHOR]

To assess the psychometric properties of a Norwegian translation of the Tinnitus Handicap Inventory (THI-NOR). A survey was sent by post to patients referred with tinnitus as their main complaint to an audiology department. Patients completed a Norwegian version of the Tinnitus Handicap Inventory (THI-NOR), a Norwegian translation of two revised subscales of the Abbreviated profile of hearing aid benefit (APHAB), the General Health Questionnaire (GHQ-12) as well as questionnaires measuring coping expectancies (TOMCATS) and neuroticism (EPI). Ninety-nine persons with tinnitus. No associations were found between THI-scores or pure-tone audiometry, gender or age. The proposed subscales of the original THI were not formed by responses from responders. The total scale shows good psychometric properties. Significant correlations were found between distress as measured by the GHQ-12, coping expectancies as measured by TOMCATS and neuroticism as measured by EPI and THI scores. THI-NOR has psychometric properties similar to those of the Danish translation (THI-DK), from which it was adapted, and to the original THI. THI-NOR seems to be a valid measure of the impact of tinnitus on a person's everyday life. Findings show that the suggested subscales of the questionnaire should be interpreted with caution.

Objective: To investigate the relationship between hearing loss (HL) and general quality of life (QoL) in adults seeking hearing aids (HAs). Design: The patients completed the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire's general part and a questionnaire measuring self-assessed communication ability (Abbreviated Profile of hearing Aid Benefit—APHAB). These responses were compared with EORTC scores from a general population and patients with former head and neck cancer. Study sample: One-hundred and fifty-eight adults with HL were recruited prior to hearing aid (HA) fitting with one half seeking renewal of their HA. Results: General QoL scores among patients with HL were similar to those in the general population, but higher than in many chronic serious diseases. Patients with unilateral HL reported slightly worse social function and more fatigue than patients with bilateral HL. Self-assessed communication ability correlated with general QoL scores. Also, we found that best ear pure tone average (PTA), cognitive and physical QoL function predicted APHAB scores. Conclusion: In the investigated HL group, general QoL scores seem to be relatively close to those seen in the general population. [ABSTRACT FROM AUTHOR]

Background: Oropharyngeal squamous cell carcinoma (OPSCC) positive for human papillomavirus (HPV) increases wolrd wide. Aims/objectives: The objective for this study has been to evaluate tumor phenotypes and tumor host responses with respect to five-year disease-specific survival (DSS) in HPV(+) and HPV(−) patients. Material and methods: Two hundred patients with OPSCC have been treated between 1992 and 2010. Histopathology slides from these patients have been morphologically evaluated in formalin-fixed, paraffin-embedded (FFPE) stained with hematoxylin-eosin (HE). From HE-stained sections tumor phenotype (keratinization, fraction of mature cancer cells and pattern of invasion) and tumor host responses (inflammation and stromal desmoplasia) were evaluated with respect to five years DSS. Results: High tumor inflammatory response and low stromal desmoplasia had an independent effect predicting better five-year DSS among all patients and when analyzed separately in the HPV(−) and HPV(+) cohort of patients using a Cox regression survival analysis that also included standard clinical prognostic variables among OPSCC patients. Conclusion: Tumor host responses, inflammation and stromal desmoplasia may become part of routine work-up in OPSCC patients due to prognostic value. Significance: We present a method, accessible in most clinical locations and would give important additional information about prognosis in OPSCC patients. [ABSTRACT FROM AUTHOR]

Conclusions: Patients with human papillomavirus (HPV)-positive tumours had better 5-year disease-specific survival (DSS) than HPV-negative patients. TNM score only predicted prognosis among HPV-negative patients. A previous history of smoking and age at diagnosis predicted DSS among HPV-positive patients whereas operability at diagnosis predicted DSS among both HPV-positive and HPV-negative patients. Objectives: HPV is a risk factor for oropharyngeal squamous cell carcinoma (OPSCC). The extent to which smoking, age and operability could play a role in HPV-positive surgically treated head and neck SCCs has not been extensively addressed previously and this study aimed to evaluate these factors. Methods: We identified 232 patients with OPSCC, of which 186 from the tonsil or base of the tongue region were treated in the period 1992-2008 in Western Norway. The 5-year DSS was recorded. Details on smoking history and whether the lesion was operable or not, as well as clinical information, were obtained retrospectively from the hospital records. Results: TNM stage predicted survival only among HPV-negative patients. A previous smoking affected prognosis only among HPV-positive patients (relative risk (RR) = 2.5; confidence interval (CI) = 1.0-6.2; p = 0.05). Increasing age of the patient had a negative effect on survival in HPV-positive patients only, especially among the oldest quartile (RR = 4.4; CI = 2.0-9.0; p < 0.001). Whether the tumour was operable or not uniquely predicted DSS both among HPV-positive (RR = 0.34; CI = 0.13-0.93; p < 0.05) and HPV-negative (RR = 0.25; CI = 0.10-0.66; p < 0.01) patients with tonsil/base of the tongue SCC.

Conclusions: We determined that 55% of the patients with oropharynx squamous cell carcinoma (OPSCC) had human papilloma virus (HPV)-positive tumors. We demonstrated that HPV-positive patients had better 5-year disease-specific survival (DSS) than the HPV-negative counterparts. This was also primarily true for cancers originating in the tonsil or base of the tongue with T3 and/or N2 tumors. Objective: Urogenital high risk (hr) HPV is an important risk factor, and probably causative agent, for OPSCC. The study investigated these factors. Methods: We identified 232 patients with OPSCC, of which 186 lesions were from the tonsil or base of the tongue region, treated in the period 1992-2008 in Western Norway. Five-year DSS was recorded for all patients. Results: In all, 124 of 226 patients had HPV-positive tumors. All except five HPV-positive patients had HPV-16-positive tumors; 69% of the patients with tonsil or base of the tongue SCC had HPV-positive tumors, whereas 14% of remaining OPSCC patients had HPV-positive tumors. Five-year DSS with HPV-positive tumor was 77% compared with 53% with an HPV-negative tumor ( p < 0.001), also valid with adjustment for age, gender, and TNM stage, but primarily determined with patients with the specific tumor sites tonsils and base of the tongue with TNM stages T3 or N2.

Conclusion: Our findings indicate a unique survival prediction from general health questionnaire (GHQ) sum scores in successfully treated head and neck squamous cell carcinoma (HNSCC) patients and also to some extent with inclusion of health-related quality of life (HRQoL) scores. Objective: To examine the survival prediction from the level of distress, measured by GHQ scores obtained from at inclusion successfully treated HNSCC patients. Methods: Structured interviews were conducted for 135 successfully treated cognitive functioning HNSCC patients 67 ± 31 (mean ± SD) months after diagnosis following a regular follow-up visit. GHQ scores, alcohol consumption history, smoking status, present comorbidities, level of neuroticism, choice of psychological coping with the cancer disease, and HRQoL scores (EORTC QLQ-C30 and -H&N35) were determined. The TNM stage, treatment provided and tumour site were obtained from the hospital records. Forty-three deaths were noted during a minimum 8.5 years of observation. Results: The GHQ sum scores predicted survival in univariate ( p < 0.05) and multivariate analyses with the above-mentioned covariates included ( p < 0.01). Using clinically relevant cut-off levels, GHQ scores predicted survival in both univariate (hazard ratio (HR) 1.9; p = 0.05) and multivariate Cox regression analyses (HR 3.8; p = 0.001). We also demonstrated survival prediction from GHQ scores when adjusted by HRQoL scores. [ABSTRACT FROM AUTHOR]

Conclusion: Our results show a significant difference between skin and cholesteatoma biology in vitro. Objectives: Cholesteatoma disease is a process of destruction characterized by uncontrolled growth of squamous epithelial cells in the middle ear or temporal bone. The pathophysiology behind the cholesteatoma development is controversial, and the mechanisms driving the cholesteatoma growth, migration and destructive properties is still unclear. We aimed to provide a method to study the effect of various compounds on cholesteatoma and skin tissue growth, as well as to further investigate the biological differences between normal skin and cholesteatoma tissue. Methods: We have established a method to study cholesteatoma biopsy tissue in vitro. Cholesteatoma tissues from patients undergoing surgery for chronic otitis were grown in culture medium and compared to growth patterns and behaviour of normal retroauricular skin. Conditioned medium was analysed for various secreted cytokines. Results: We found a radial outgrowth of keratinocyte epithelium from the circular biopsies. After 5 days of culture we found a significant growth of both cholesteatoma and skin-derived cells. Cholesteatoma samples showed higher growth rate as compared with skin control cultures from the same patient. Moreover, the cholesteatoma cells showed higher production of monocyte chemoattractant protein-1 (MCP-1) and interleukin (IL)-6 as compared with normal skin. [ABSTRACT FROM AUTHOR]

Monocyte fragment (F)-spheroid-stimulated and F-spheroid IL-6 and monocyte chemotactic protein (MCP)-1 secretion are related to inflammatory state, macrophage density and the TNM stage of patients with head and neck squamous cell carcinoma (HNSCC). Fragment (F)-spheroids from HNSCC patients in vitro secrete and stimulate autologous monocytes to secrete IL-6 and MCP-1. The aim of this investigation was to study this cytokine secretion in relation to other cytokines, spheroid composition and host factors. In series I ( n =14) the densities of epithelial cells, fibroblasts and macrophages were determined in sections from F-spheroids and donor tissue. In series II ( n =17) the TNM stage, donor inflammatory state, macrophage density and the secretion of F-spheroid- and monocyte F-spheroid-stimulated IL-6, MCP-1 and tumor necrosis factor (TNF)-α were determined. Epithelial cells were partly replaced by interstitial tissue during spheroid formation. Malignant (M) F-spheroids secreted more MCP-1 than benign (B) F-spheroids. No F-spheroid secreted measurable amounts of TNF-α. Monocytes secreted more IL-6 when co-cultured with MF- compared to BF-spheroids. Monocyte IL-6 MF- and MCP-1 MB-spheroid-stimulated secretion correlated with macrophage density. In addition, there was an association between MF- and BF-spheroid-stimulated monocyte cytokine secretion, as well as between BF- and MF-spheroid-stimulated MCP-1 secretion. An inverse relation was also noted between the erythrocyte sedimentation rate at monocyte harvest and the monocyte MCP-1 F-spheroid responses. [ABSTRACT FROM AUTHOR]

Conclusions At diagnosis, control patients had the lowest depression levels and anxiety scores, followed by those with limited HNSCC disease and these with extended HNSCC disease.Anxiety and depression levels at diagnosis predicted prognosis via an association with extent of disease. Sense of humor, but not anxiety score or depression level, predicted lower QoL and depression levels at follow-up. Objective To study the association between anxiety score, depression level and sense of humor at diagnosis in head and neck squamous cell carcinoma (HNSCC) patients versus TNM stage, prognosis and depression level/quality of life (QOL) 6 years following diagnosis. A control group of patients with benign HN disease was also included. Material and methods Male patients with newly diagnosed HNSCC (n=78) or benign HN (n=61) disease completed the following questionnaires: the Beck Depression Inventory, the Spielberger Trait Anxiety Inventory (state) and the Svebak humor questionnaire. Patients with cachexia or those aged >80 years were excluded. In the HNSCC patients, TNM stage, prognosis and QOL/depression level (n=27) were determined following successful therapy. Results HNSCC patients reported higher anxiety scores and lower depression levels than control patients, although there was overlap between the groups. N stage was associated with high anxiety scores and depression levels, whereas T stage was only associated with depression levels. Both anxiety scores and depression levels at diagnosis predicted prognosis through an association with TNM stage. Sense of humor, but not depression levels or anxiety scores, at diagnosis predicted QoL and depression level at follow-up. [ABSTRACT FROM AUTHOR]

Objective—We aimed to study whether personality scores, as measured using the Eysenck Personality Inventory (EPI), are associated with the risk and prognosis of head and neck squamous cell carcinoma (HNSCC). Material and methods—A total of 78 male patients with newly diagnosed HNSCC and 61 male patients with benign HN disease completed the EPI, which assesses the following: neuroticism, extraversion and lie score. The TNM stage, prognosis, diagnostic delay, level of education and smoking and alcohol consumption histories of the patients were also recorded. Patients with cachexia and those aged > 80 years were excluded. Results—The cancer patients had higher neuroticism scores (10.7 ± 0.5 vs 8.3 ± 0.6; p < 0.01) than the control patients. This association was shown to be secondary to the fact that neuroticism is associated with increased alcohol consumption. The personality trait scores were not associated with the length of diagnostic delay. It was also suggested that a low lie score predicted disease-specific death in the HNSCC patients (p = 0.02). Total survival also seemed to be predictable (p < 0.05). Conclusion—Neuroticism is probably associated with a risk of HNSCC as a result of increased alcohol consumption. If the prognostic results can be replicated, a potentially important association between this personality trait and the prognosis of HNSCC is suggested. [ABSTRACT FROM AUTHOR]

We have previously shown an increased T lymphocyte and monocyte responsiveness in peripheral blood mononuclear cells (PBMC) from patients with head and neck squamous cell carcinoma (HNSCC) compared with PBMC from control patients. This study reports T lymphocyte function of PBMC of 81 patients with HNSCC dependent on disease stage and prognosis. Males with HNSCC under 80 years of age without cachexia, with no auto-immune disease or previous cancer and on no immuno-active medication were included at the time of diagnosis of disease. The follow-up was for at least 18 months. When cells from patients with early vs late stage disease according to the T, N or T+N stage of HNSCC were compared, decreased in vitro mitogen-stimulated and spontaneous T cell proliferation was seen with increasing tumour stage. When patients were studied according to disease-specific survival, a decreased T lymphocyte mitogen-stimulated proliferation was observed to be associated with a poorer prognosis. No changes in prognosis were noticed related to decreased γ-IFN, IL-2 or IL-4 level of the supernatants of the T lymphocyte-stimulated PBMC in vitro cultures. With stratification for disease stage, we determined that PBMC in vitro T lymphocyte-stimulated proliferation predicted outcome for the HNSCC patients. The results were similar for both laryngeal and oral cavity/pharyngeal cancers. The present investigation provides evidence to support the idea that the relationship between HNSCC and the immune system of the host may provide clinically useful information about prognosis.
