RESUMO
PURPOSE: To evaluate the association between dry eye disease (DED) symptoms and daily beverage intake among adults in Saudi Arabia. PATIENTS AND METHODS: In this cross-sectional, questionnaire-based study, we distributed an online questionnaire to men and women older than 18 years living in Saudi Arabia. The questionnaire consisted of items related to the sociodemographic characteristics of the participants and two validated indices: the Ocular Surface Disease Index (OSDI) and the brief 15-item Beverage Intake Questionnaire (BEVQ-15). Participants were excluded if they were aged less than 18 years; wore contact lenses; had existing eye disease (excluding refractive errors), history of eye surgery (including corrective eye surgeries), or autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome); or were currently taking specific medications including antidepressants, antihistamines, and diuretics. RESULTS: After applying the study exclusion criteria, a total of 615 participants were included in the statistical analysis. The majority of participants were 18-34 years old (450, 73.2%), and men (381, 62%) exceeded women (234, 38%) by approximately 1.5-fold. OSDI scores showed that 344 participants (55.9%) had DED symptoms, 145 (23.6%) had mild dry eyes; and 106 (17.2%) and 93 (15.1%) had moderate and severe dry eyes, respectively. There was a significant association between sex and DED symptoms (p = 0.012); the frequency of DED symptoms in women exceeded that in men. However, no significant differences were observed with other demographic data such as age and location of residence. Although beverage intake was moderately correlated to OSDI score (R = 0.27), we found no significant association between beverage intake and DED symptoms. CONCLUSION: This is the first study to highlight the association between DED symptoms and daily beverage intake. We found a significant association between DED symptoms and female sex. However, no significant association was found between DED symptoms and other demographic characteristics or beverage intake.
RESUMO
OBJECTIVES: A limited number of publications from the Middle East have focused on neuroblastoma, a common childhood malignancy. This study describes the clinical characteristics and survival outcome of Omani children with neuroblastoma treated at the National Oncology Centre, Oman, between 2010 and 2017. METHODS: From January 2010 to December 2017, data on Omani children aged less than 13 years with neuroblastoma were retrospectively collected. Survival data were statistically correlated with known prognostic factors, including age, stage of disease, MYCN profile and presence of metastasis. RESULTS: A total of 56 Omani children were included. in this study. The male to female ratio was 1:1. The mean age at presentation was one year and 10 months. The two most common presenting complaints were body masses (48.2%) and constitutional symptoms (33.9%). Approximately, 54.5% were high risk, 35.7% were intermediate risk and 9.8% were low risk. High-risk neuroblastoma was mainly found in children older than one year (76.6%), with low risk mainly observed in children less than one year of age (80%). The overall survival of all groups combined was 74% (P <0.05); the event-free survival (EFS) was 67% (P <0.05). The overall survival rates over five years for the high-risk, intermediate-risk and low risk groups were 60%, 88% and 100%, respectively, and the EFS was 51%, 79% and 100%, respectively. CONCLUSION: Omani children with neuroblastoma mainly presented with masses or constitutional symptoms and had an advanced disease at presentation which was associated with inferior survival. The survival outcomes were reasonably similar to published international data.
