INTRODUCTION: The Lund-MacKay score (LMS) correlates poorly with chronic rhinosinusitis (CRS) symptom severity. Patients with CRS also tend to report relatively lower levels of mental wellbeing. Our purpose was to determine if there is a correlation between socio-economic status (SES) and CRS severity as measured by the LMS, and if there is an association between depression symptoms and the severity of CRS using the LMS.
METHODS: A total of 127 patients diagnosed with CRS were prospectively recruited and assessed with a sinonasal assessment questionnaire (SNAQ-11), and the Patient Health Questionnaire (PHQ-9) for depression. Each patient’s education level, family income, and smoking behavior were determined. The sinus CT scan was scored using the LMS. The data were analyzed using ordinary least squares (OLS) regression techniques.
RESULTS: Having a highschool education or less was associated with higher SNAQ-11 scores while being a daily smoker was associated with higher SNAQ-11 scores. There was no significant relationship between educational attainment, financial income or daily smoking and sinus CT score. Including depression scores in the SNAQ-11, regression equations indicated a significant and positive relationship between depression severity and SNAQ-11 score. CRS with polyps was negatively associated with SNAQ-11 scores but, as expected, it was positively associated with a higher LMS.
CONCLUSIONS: Lower SES status is a negative modifying factor of subjective CRS severity but it has no impact on the LMS. Depression symptoms are associated with increased subjective CRS severity but they have no effect on the LMS. How SES and depression impact on a patient’s self-reported disease severity requires further study.

Olfactory dysfunction appears to be one of the earliest signs of several age-related neurodegenerative disorders, including Alzheimer’s disease (AD) or Parkinson’s disease (PD). To rate performance and olfactory deficits in patients with cognitive disorders, various olfactory tasks have been used such as odor detection, discrimination, recognition memory, identification and naming but no study has been focused on just noticeable difference (JND), a sensitive tool of detection. The aim of this study was to investigate and compare variations in JNDs in healthy elderly and in patients with cognitive disorders associated with dementia. The results showed significantly higher olfactory JNDs in a population with cognitive disorders associated with dementia - i.e. a lower olfactory detection performance - compared to a control population paired in age, gender and education level. Additionally, the findings of the present study showed strong correlations between cognitive performances and JND scores in the control population contrary to the patient population. These findings are discussed in relation to the relevance of using olfactory JNDs in the diagnosis of dementias.

Photodynamic therapy has been used in treating immune-mediated dermatological conditions such as psoriasis and atopic dermatitis. There are emerging reports on the efficacy of intranasal phototherapy in allergic rhinitis. The aim of this review was to assess intranasal phototherapy in the treatment of allergic rhinitis, with particular emphasis on clinical efficacy, scientific basis and safety. A structured search of the U.S. National Library of Medicine (PubMed), the Cochrane Collaboration library, Google Scholar and ISI Web of Knowledge database was undertaken using MeSH terms ‘phototherapy’ and ‘rhinitis.’ Fourteen full-text articles were available for review. Three different phototherapy medical devices were assessed: (1) Bionase™, (2) Allergy Reliever SN206 and (3) Rhinolight®. Light wavelength used in these devices ranged from red light to ultraviolet. Clinical use of intranasal phototherapy appears to be safe and well tolerated. Most studies demonstrated symptomatic improvement and quality of life scores. No improvement in objective measures of nasal airflow was demonstrated. Beneficial effects of phototherapy on inflammatory markers remain equivocal. Phototherapy treatment results in DNA damage but does not appear to predispose to carcinogenesis. However, long-term prospective studies are required to verify this. The quality of published studies was variable and thus the current strength of recommending intranasal phototherapy is currently weak.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a T helper-2 (Th2) inflammatory disease with considerable impact on the quality of life. Staphylococcus aureus enterotoxins (SAEs) can induce and/or amplify inflammation. In this study, we investigated the immunomodulatory effect of SAEs on cytokine production by T cell obtained from nasal polyps (NPs) and examined whether neutralizing interleukin 5 (IL-5) can reverse the immunological effect mediated by those toxins.
METHODS: NP tissues were obtained from all patients who underwent endoscopic sinus surgery for CRSwNP. NP cells were isolated and stimulated in vitro with SAEs in the presence or absence of anti-IL-5. Flow cytometry (FACS) analyses were performed to measure specific T lymphocyte cytokine production.
RESULTS: Seventeen patients (mean age 48 years) were enrolled. SAEs significantly increased the IL-4, IL-5 (Th2) and interferon (INF)-γ (Th1) cytokines released from T lymphocytes of NPs. The addition of anti-IL-5 suppressed IL-4 and INF-γ release, which was most evident on NP tissue with high basal levels of IL-5.
CONCLUSIONS: Neutralizing IL-5 is a potential therapeutic modality in patients with NPs, the effect of which is dependent on IL-5 levels.

BACKGROUND: Intestinal-type sinonasal adenocarcinoma (ITAC) is an epithelial cancer of the sinonasal sinuses that shows histological similarity to colorectal cancer (CRC) and share chronic inflammation as a possible etiological factor. The Wnt-pathway is one of the most important tumourigenic pathways in CRC. The aim of this study was to investigate if the Wnt-pathway is activated in ITAC.
METHODOLOGY: Protein expression profiles of E-cadherin, β-catenin, c-myc and cyclin D1 were analysed by immunohistochemistry in 83 samples of ITAC, organized into tissue microarray blocks.
RESULTS: Nuclear β-catenin expression was observed in 31% of the cases and was twice as frequent in papillary/colonic ITAC compared to solid/mucinous subtypes. Loss of membranous β-catenin staining occurred in 24% and loss of membranous E-cadherin in 6% of the cases and this was more prominent in mucinous types. Strong c-myc and cyclin D1 expression was observed in 30% and 4% of the cases, respectively. Nuclear β-catenin expression was significantly related to poor clinical outcome, independent from established factors as tumour stage and histological type.
CONCLUSION: The presence of nuclear β-catenin in 31% of patients with ITACs indicated that in a subset of patients, the Wnt-pathway is active and conveys a worse prognosis.
