“…Radiographic findings for paranasal sinuses are usually assessed by otorhinolaryngologists using standard computed tomography [5,6]. However, computed tomography places a higher risk on the patient due to high doses of radiation, and the use of CT in patient management has increased the overall radiation burden [7]. Cone beam computed tomography (CBCT) was first described in 1980 and was first applied to dentomaxillofacial radiology in 1998 [8][9][10][11].…”

Correlation of cone beam computed tomography (CBCT) findings in the maxillary sinus with dental diagnoses: a retrospective cross-sectional study

et al. 2011

This study was conducted to assess the coincidence of mucosal hyperplasia in the maxillary sinus and related clinical diagnoses of posterior maxillary teeth found in cone beam computed tomography (CBCT) scans. A total of 204 patients who underwent CBCT examinations between 2006 and 2008 were evaluated retrospectively. Clinical and CBCT findings were correlated using patient records. Absolute frequencies, odds ratios (OR), and 95% confidence intervals (95% CI) were calculated for statistical evaluations. There was a pronounced association between periodontitis and radiological signs of sinusitis. Basal mucosal wall thickening was more likely in patients with decayed and non-vital teeth compared to patients with sound teeth (OR = 5.2; 95% CI = 1.2-23.1). Basal mucosal wall thickening was also more likely than total mucosal thickening (OR = 10.4; 95% CI = 2.6-42.2). Patients with decayed and endodontically treated teeth were more likely to exhibit involvement of the basal wall (OR = 9.2; 95% CI = 3.3-25.2) than were patients with healthy teeth. CBCT examinations revealed a correlation between basal mucosal thickening in the maxillary sinus and decayed posterior maxillary teeth or periodontitis. Chronic symptoms involving the sinuses are one of the most common reasons for patients to consult physicians. One reason for chronic orofacial pain is the prevalence of undiagnosed sinus conditions.

“…First, ionizing radiation in young children may have potential late adverse effects. [8][9][10] Second, the lack of findings on CR does not rule out the diagnosis if there is a strong suspicion of pneumonia. 3 Finally, although a chest computed tomography (CT) scan has a higher level of diagnostic accuracy than CR, it is almost never used for the diagnosis of pneumonia because of higher ionizing radiation exposure, difficulty in patient cooperation, frequent need for sedation, and cost.…”

Lung Ultrasound for the Diagnosis of Pneumonia in Children: A Meta-analysis

et al. 2015

BACKGROUND AND OBJECTIVE: Pneumonia is the leading cause of death of children. Diagnostic tools include chest radiography, but guidelines do not currently recommend the use of lung ultrasound (LUS) as a diagnostic method. We conducted a meta-analysis to summarize evidence on the diagnostic accuracy of LUS for childhood pneumonia. METHODS:We performed a systematic search in PubMed, Embase, the Cochrane Library, Scopus, Global Health, World Health Organization-Libraries, and Latin American and Caribbean Health Sciences Literature of studies comparing LUS diagnostic accuracy against a reference standard. We used a combination of controlled key words for age ,18 years, pneumonia, and ultrasound. We identified 1475 studies and selected 15 (1%) for further review. Eight studies (765 children) were retrieved for analysis, of which 6 (75%) were conducted in the general pediatric population and 2 (25%) in neonates. Eligible studies provided information to calculate sensitivity, specificity, and positive and negative likelihood ratios. Heterogeneity was assessed by using Q and I 2 statistics.RESULTS: Five studies (63%) reported using highly skilled sonographers. Overall methodologic quality was high, but heterogeneity was observed across studies. LUS had a sensitivity of 96% (95% confidence interval [CI]: 94%-97%) and specificity of 93% (95% CI: 90%-96%), and positive and negative likelihood ratios were 15.3 (95% CI: 6.6-35.3) and 0.06 (95% CI: 0.03-0.11), respectively. The area under the receiver operating characteristic curve was 0.98. Limitations included the following: most studies included in our analysis had a low number of patients, and the number of eligible studies was also small. Dr Pereda conceptualized and designed the study, reviewed all abstracts and selected articles to be included in the meta-analysis, was responsible for data collection, and drafted the initial manuscript; Dr Chavez conceptualized and designed the study, reviewed all abstracts and selected articles to be included in the meta-analysis, was responsible for data collection, led the analysis, and drafted the initial manuscript; Dr Hooper-Miele participated in analysis and interpretation of results, critically revised ultrasound methods used by selected studies, and reviewed and revised the manuscript; Drs Gilman, Steinhoff, Ellington, and Tielsch participated in the analysis and interpretation of results and reviewed and revised the manuscript; Ms Gross and Ms Price conducted the literature search and reviewed and revised the manuscript; Dr Checkley conceptualized and designed the study, contributed equally to the analysis, drafted the initial manuscript, and had ultimate oversight over the study conduct, analysis plan, and writing of the manuscript; and all authors approved the final manuscript as submitted and agree to be accountable for all aspects of the work.www.pediatrics.org/cgi

“…Children are even more radiation sensitive. It is estimated that a 1-year-old infant is 10 to 15 times more likely to develop cancer due to a radiation dose than an adult who receives the same dose (Mazrani et al 2007, p. 1127. Cf.…”

Radiation Protection—Sorting Out the Arguments

This is a response to an article by Wade Allison in which he argues that we should accept drastically higher doses of ionizing radiation than what we currently do (Philosophy and Technology 24:193-195, 2011). He employs four arguments in defence of his position: comparisons with background radiation, the positive experiences of radiotherapy, the presence of biological defence mechanisms against radiation, and a concession by Swedish authorities that their approach to reindeer meat after the Chernobyl fallout was unnecessarily strict. It is shown that each of the four arguments is fallacious. In conclusion, the traditional weighing of risks against benefits in radiation protection is defended.
