A diagnostic comparison of panoramic and intraoral radiographs

Objective. This study compared panoramic and intraoral radiographic surveys in the evaluation of specific dental pathoses in Air Force personnel.Study design. The radiographs of 30 subjects were read singly and in various combinations: panoramic survey only; periapicals plus bitewings; panoramic survey plus bitewings; and panoramic survey plus periapicals plus bitewings. Three independent, blinded examiners using standardized viewing conditions assessed the radiographs in random order for the presence of caries, periapical pathoses, bone loss, furcation involvement, impacted/unerupted teeth, internal/external root resorption, and retained roots. The consensus radiographic standard of true pathosis was the simultaneous interpretation by the three examiners of all radiographs for each subject.Results and Conclusions. The panoramic survey by itself was shown to have the lowest correlation with the consensus radiographic standard when basic military trainees with generalized dental pathoses were evaluated. The combination of panoramic survey plus bitewing radiographs exhibited a diagnostic yield for specific pathoses that was comparable to that of panoramic survey plus bitewings plus periapicals.     

Systematic review of acupuncture to control hot flashes in cancer patients

Hot flashes (HFs) are a common side effect of cancer treatment. The purpose of this systematic review was to evaluate evidence related to the use of acupuncture for HFs in cancer patients. EMBASE, MEDLINE, Cochrane (all databases), PubMed, the Cumulative Index to Nursing and Allied Health Literature, and Scopus were searched from their inception through December 2014. Included studies had to be randomized controlled trials with a usual‐care and/or placebo comparison group that investigated acupuncture to treat HFs in cancer patients. No language limits were applied. The risk of bias (ROB) was rated as low, high, or unclear according to Cochrane criteria. Both within‐group and between‐group changes were evaluated. Four hundred two items were identified, and 192 duplicates were omitted; this left 210 publications to be screened. Eight studies met the inclusion criteria, and all involved women with breast cancer. All studies showed significant within‐group improvement from the baseline for true acupuncture (TA). One study showed significant improvement in favor of TA over sham acupuncture (SA; P < .001), 1 study found in favor of TA over SA for nighttime HFs only (P = .03), and 1 study found in favor of TA over SA or untreated controls (P < .01 and P < .001, respectively). Between‐group (TA vs SA) effect size (ES) estimates for daytime and nighttime HFs were calculated (ES range, 0.04‐0.9) whenever possible. No studies were rated with a low ROB. In conclusion, the current level of evidence is insufficient to either support or refute the benefits of acupuncture for the management of HFs in cancer patients. Future studies should provide within‐group and between‐group ES estimates in addition to P values. Cancer 2015;121:3948–3958. © 2015 American Cancer Society.     

In memoriam of Alan H. Adams,DC, MS,MSEd:: Health professions educator and chiropractic research pioneer

In this paper we pay homage to Dr Alan H. Adams, who was born on November 3, 1945, and passed away on December 26, 2020. An early adopter of problem-based learning and evidence-based medicine, he contributed substantially to improving chiropractic education, research, and developing an evidence-based practice mindset for chiropractic practice. People who knew Al best recall that he was a fluent instigator of collaborative relationships, and he inspired and advanced many people in their academic and scientific careers. His curiosity, expertise, and mentorship were appreciated by many people and developed numerous interprofessional collaborations.     

Youthful habits of work and recreation and later cancer among physicians

Scores on seven factors derived from a Habits of Work and Recreation Survey administered to 1,038 white male medical students 17 to 35 years ago were used to compare students who subsequently developed some form of major cancer with those who did not. With the Type I error rate controlled through use of multivariate analysis of variance and age and smoking ruled out as possible confounding variables, the two groups were significantly differentiated, primarily in terms of intellectual interests—cancer cases having fewer. Students at or below the overall mean on the intellectual interests measure were more than three times as likely to develop cancer as were students with scores above the mean. In this population, the results appear interpretable in terms of the stamina concept, in which few intellectual interests may reflect an absence of stamina and spontaneity and/or failure to meet subcultural expectations—factors possibly associated with increased cancer risk.
