Intratympanic steroid treatment for sudden deafness: a meta-analysis of randomized controlled trials
No full textBackground: The efficacy of intratympanic steroid (ITS) treatment in sudden deafness (SD) remains controversial. To shed light on this issue, we performed a systematic review of randomized controlled trials to assess the overall efficacy of ITS therapy and to clarify whether it is more suitable as a first-line approach (primary treatment) or as a salvage treatment when traditional systemic agents have failed.Methods: An electronic database search (MEDLINE and PubMed) was performed with the objective of identifying all studies published in the English language between January 1980 and November 2011 on the efficacy of ITS in the treatment of SD. All relevant articles were retrieved, and the related reference lists were reviewed systematically to identify other reports that could be included. Data were synthesized using the Mantel-Haenszel model. Results are expressed as odds ratio (OR) with 95% confidence interval (CI).Results: A total of 11 randomized studies including 472 subjects allocated to ITS and 453 controls were selected. Intratympanic steroid regimens used and treatments administered to controls varied widely across studies. When considering together trials investigating ITS therapy as a primary (n = 4) or salvage (n = 7) treatment, the common OR for recovery was 1.7 (95% CI, 1.3-2.3). When considering them separately, the common ORs for recovery were 0.9 (95% CI, 0.7-1.6) for primary and 2.9 (95% CI, 1.9-4.5) for salvage therapy.Conclusion: Intratympanic steroid therapy seems to confer a certain degree of benefit as a salvage but not as a primary treatment of SD. However, further evidence is needed to clarify some yet uncertain aspects, such as the optimal protocol of therapy
Recurrences of surgery for antrochoanal polyps in children: A systematic review.
No full textObjectives: The main purpose was to evaluate the recurrence rate after surgery for antrochoanal polyps (ACPs) in children; secondly, we have analyzed the rate of recurrence for different types of surgery and the risk factors involved.
Methods: We performed a systematic review searching PubMed and MEDLINE databases including English language published studies from June 1989 to October 2017 regarding surgical treatment of ACPs in children.
Results: We included thirteen studies, eight were retrospective and five prospective, with 285 participants, the mean rate of recurrence after ACPs surgery was 15.0% (95% CI:11.0-20.0). Functional endoscopic sinus surgery (FESS) was the main type of surgery used for primary cases (75.4%) followed by the combined approach i.e. FESS with a transcanine sinusoscopy or mini Caldwell-Luc (14%), the Caldwell-Luc (CWL) (8%) and simple polypectomy (SP) (2.8%). Our analysis has demonstrated a significant reduction of recurrences using the combined approach 0% (95% CI: 0.0-8.0) compared with FESS 17.7% (95% CI: 12.8-23.4) or SP 50% (95% CI:15.7-84.3) (p .05). The analysis of the possible risk factors involved in recurrences are inconclusive.
Conclusion: Recurrences of ACPs in children are still high. The endoscopic sinus surgery is considered the first choice for primary treatment, whilst the external approach may be a valid option in case of recurrence. It seems that the combined approach could reduce recurrence rates in selected patients that cannot be completely managed with endoscopy
Dietary patterns and oesophageal cancer: a multi-country latent class analysis
No full textBackground: The considerable differences in food consumption across countries pose major challenges to the research on diet and cancer, due to the difficulty to generalise and reproduce the dietary patterns identified in a specific population.
Methods: We analysed data from a multicentric case-control study on oesophageal squamous cell carcinoma (ESCC) carried out between 1992 and 2009 in three Italian areas and in the Canton of Vaud, Switzerland, which included 505 cases and 1259 hospital controls. Dietary patterns were derived applying LCA on 24 food groups, controlling for country membership, and non-alcoholic energy intake. A multiple logistic regression model was used to derive odds ratio (ORs) and corresponding 95% CIs for ESCC according to the dietary patterns identified, correcting for classification error.
Results and conclusion: We identified three dietary patterns. The 'Prudent' pattern was distinguished by a diet rich in fruits and vegetables. The 'Western' pattern was characterised by low consumption of these food groups and higher intakes of sugar. The 'Lower consumers-combination pattern' exhibited a diet poor in most of the nutrients, preferences for fish, potatoes, meat and a few specific types of vegetables. Differences between Italy and Switzerland emerged for pattern sizes and for specific single food preferences. Compared to the 'Prudent' pattern, the 'Western' and the 'Lower consumers-combination' patterns were associated with an increased risk of ESCC (OR=3.04, 95% CI=2.12-4.38 and OR=2.81, 95% CI=1.65-4.76)
Global trends in nasopharyngeal cancer mortality since 1970 and predictions for 2020 : Focus on low-risk areas
No full textNasopharyngeal cancer (NPC) mortality shows great disparity between endemic high risk areas, where non-keratinizing carcinoma (NKC) histology is prevalent, and non-endemic low risk regions, where the keratinizing squamous cell carcinoma (KSCC) type is more frequent. We used the World Health Organization database to calculate NPC mortality trends from 1970 to 2014 in several countries worldwide. For the European Union (EU), the United States (US) and Japan, we also predicted trends to 2020. In 2012, the highest age-standardized (world standard) rates were in Hong Kong (4.51/100,000 men and 1.15/100,000 women), followed by selected Eastern European countries. The lowest rates were in Northern Europe and Latin America. EU rates were 0.27/100,000 men and 0.09/100,000 women, US rates were 0.20/100,000 men and 0.08/100,000 women and Japanese rates were 0.16/100,000 men and 0.04/100,000 women. NPC mortality trends were favourable for several countries. The decline was −15% in men and −5% in women between 2002 and 2012 in the EU, −12% in men and −9% in women in the US and about −30% in both sexes in Hong Kong and Japan. The favourable patterns in Europe and the United States are predicted to continue. Changes in salted fish and preserved food consumption account for the fall in NKC. Smoking and alcohol prevalence disparities between sexes and geographic areas may explain the different rates and trends observed for KSCC and partially for NKC. Dietary patterns, as well as improvement in management of the disease, may partly account for the observed trends, too
Prevalence and Determinants of Tinnitus in the Italian Adult Population
No full textBackground: Limited, outdated, and poor quality data are available on the prevalence of tinnitus, particularly in Italy. Methods: A face-to-face survey was conducted in 2014 on 2,952 individuals, who represented the Italian population aged 18 or more (50.6 million). Any tinnitus was defined as the presence of ringing or buzzing in the ears lasting for at least 5 min in the previous 12 months. Results: Any tinnitus was reported by 6.2% of Italian adults, chronic tinnitus (i.e. for more than 3 months) by 4.8%, and severe tinnitus (i.e. which constitutes a big or very big problem) by 1.2%. The corresponding estimates for the population aged ≥45 years were 8.7, 7.4 and 2.0%, respectively. Multivariable analysis on population aged ≥45 years revealed that old age (odds ratio (OR) = 4.49 for ≥75 vs. 45-54 years) and obesity (OR = 2.14 compared to normal weight) were directly related to any tinnitus, and high monthly family income (OR = 0.50) and moderate alcohol consumption (OR = 0.59 for <7 drinks/week vs. non-drinking) were inversely related. Conclusions: This is the first study on tinnitus prevalence among the general Italian adult population. It indicates that in Italy tinnitus affects more than 3 million adults and is felt as a major problem by more than 600,000 Italians, mostly aged 45 years or more
Age-period-cohort analysis of oral cancer mortality in Europe : the end of an epidemic?
No full textOver the last decade, mortality from oral and pharyngeal cancer has been declining in most European countries, but it had been increasing substantially in Hungary, Slovakia and a few other countries of central Europe, reaching rates comparable to those of lung cancer in several western European countries in males. To update trends in oral cancer mortality and further analyse the recent epidemic in central Europe, official death certifications for oral and pharyngeal cancer for 37 European countries were derived over the period 1970-2007, and an age-period-cohort model was fitted for selected countries. Male oral cancer mortality continued to decline in most European countries, including the Russian Federation, and, more importantly, it also started to decline in some of the countries with the highest male rates, i.e. Hungary and Slovakia; persisting rises were, however, observed in Belarus, Bulgaria and Romania. Oral cancer mortality rates for women were lower than in men and showed no appreciable trend over recent periods in the EU overall. Estimates from the age-period-cohort analysis for most selected countries showed a fall in effects for the cohorts born after the 1950s. For the period effect displayed a rise for the earlier periods, an inversion in the 1990 s and a continuous fall up to the last studied period. Only some former non-market economy countries, like Romania, Ukraine and Lithuania, had rising cohort effect trends up to most recent generations. The major finding of this updated analysis of oral cancer mortality is the leveling of the epidemic for men in most European countries, including Hungary and other central European countries, where mortality from this cancer was exceedingly high. These trends essentially reflect the changes in alcohol and tobacco consumption in various populations
The Role of Diet in Tinnitus Onset: A Hospital-Based Case-Control Study from Italy
No full textKnowledge on the role of diet in tinnitus onset is mostly based on few cross-sectional studies. In 2016–2019 we conducted a hospital-based case-control study in northern Italy on 185 incident idiopathic tinnitus cases and 198 controls, providing data on dietary habits through a 37-item food-frequency questionnaire. Odds ratios (OR) for tinnitus risk were derived through unconditional multiple logistic regression models. Moderate-to-high vs. low intake of caffeine (OR, 0.49; 95% confidence interval (CI), 0.24–0.99) and butter (OR, 0.46; 95% CI, 0.23–0.93), and high vs. low intake of poultry (OR, 0.43; 95% CI, 0.23–0.81), prosciutto (OR, 0.44; 95% CI, 0.23–0.85), and legumes (OR, 0.50; 95% CI, 0.28–0.92) were inversely associated with tinnitus onset. Other food items, including cereals, red meat, fish, vegetables, and fruit did not show any statistically significant relationship. The variety of food consumed decreased the risk of tinnitus (OR for at least 20 vs. less than 16 different food items, 0.47; 95% CI, 0.24–0.90). Our findings highlight the importance of diet in tinnitus onset and confirm a potential inverse association of protein-rich food and caffeine on the incidence of tinnitus. Confirmation of our findings in longitudinal studies is necessary before proving any diet recommendations for tinnitus prevention
Prognostic influence of gender in patients with oral tongue cancer
No full textObjectives: The purpose of this study was to evaluate the independent role of gender in affecting prognosis in patients with anterior tongue cancer. Design: Patients recorded in the head and neck cancer registry of Milano-Bicocca School of Medicine between January 1981 and December 1998 were reviewed. Female patients with squamous cell carcinoma of the tongue were identified and matched to men for year of diagnosis, age, TNM classification, histologic grading, and treatment modalities. For each woman, two men were matched. Results: Seventy-one women and 142 men satisfied our selection criteria. The frequency of recurrences was similar in the two study groups. This event occurred in 33 (46%) women and in 78 (55%) men (Fisher exact test, P = 0.25). The survival analysis confirmed that the rate of recurrences did not differ (log-rank test, P = 0.31). The number of cancer-related deaths in women and men was 23 (32%) and 55 (39%), respectively (Fisher exact test, P = 0.45). The survival analysis confirmed that gender did not affect survival (log-rank test, P = 0.34). Conclusion: In this study, gender does not influence prognosis in patients with oral tongue cancer
Inflammatory potential of diet and risk of oral and pharyngeal cancer in a large case-control study from Italy
No full textDiet and inflammation have been suggested to be important risk factors for oral and pharyngeal cancer. We examined the association between dietary inflammatory index (DII) and oral and pharyngeal cancer in a large case-control study conducted between 1992 and 2009 in Italy. This study included 946 cases with incident, histologically confirmed oral and pharyngeal cancer, and 2492 controls hospitalized for acute non-neoplastic diseases. The DII was computed based on dietary intake assessed by a valid 78-item food frequency questionnaire and was adjusted for non-alcohol energy intake using the residual approach (E-DII). Logistic regression models were used to estimate odds ratios (ORs), and 95% confidence intervals (CIs), adjusted for age, sex, non-alcohol energy intake, study center, year of interview, education, body mass index, tobacco smoking, and alcohol drinking. Subjects with higher DII scores (i.e., with a more pro-inflammatory diet) had a higher risk of oral and pharyngeal cancer, the OR being 1.80 (95% CI 1.36-2.38) for the highest versus the lowest DII quartile and 1.17 (95% CI 1.10-1.25) for a one-unit increase (8% of the DII range). When stratified by selected covariates, a stronger association was observed among women (ORquartile4 v.1 3.30, 95% CI 1.95-5.57). We also observed stronger association for oral cancer subsite and a strong combined effect of higher DII and tobacco smoking or alcohol consumption on oral and pharyngeal cancer. These results indicate that the pro-inflammatory potential of the diet, as shown by higher DII scores, is associated with higher odds of oral and pharyngeal cancer
Head-to-head comparison of single-breath and tidal-breath exhaled nitric oxide measurements
No full textBackground:
Exhaled nitric oxide (eNO) is an endogenous gas involved in airway pathophysiology and is determined in orally exhaled air by various techniques. However, traditional single-breath technique (eNOSB) requires active cooperation and is not always easily practicable (especially in young children); simpler techniques including tidal breathing measurements (eNOTB) are not standardized. The aim of this study was to evaluate the possible correlation and correspondence between eNOSB and eNOTB and the impact of potential confounders in children with chronic adenotonsillar disease.
Methods:
Eighty-six children (mean age 8.7 ± 3.2 y) underwent eNO assessment by means of eNOSB and eNOTB. The correlation among eNOTB, eNOSB, and other potential confounders (i.e., gender, age, weight, height, BMI, and passive smoking exposure) were studied.
Results:
The analyses showed a poor correspondence between eNOSB and eNOTB, with the latter underestimating (P < 0.001) mean eNO values: 6.4 parts per billion (ppb) (95% confidence interval (CI): 8.4–11.4 ppb) vs. 9.8 ppb (95% CI: 5.6–7.3 ppb). A greater correlation was found between eNOSB and eNOTB in children younger than 6 y. Only eNOSB and age predicted eNOTB (R2 = 43.6%).
Conclusion:
eNOTB is not a good predictor of eNOSB in children. Constant-flow eNOSB is the technique of choice for eNO assessment in young children
