Coronary artery disease is a global challenge for healthcare systems. Early diagnosis is a key issue to improve quality of life and reduce morbidity and mortality. Diagonal earlobe crease, a wrinkle extending obliquely across the earlobe, was linked by many authors to various atherosclerotic diseases. This systematic review aimed at summarizing the diagnostic accuracy of diagonal earlobe crease for diagnosis of chronic and acute coronary syndromes in adults. Cochrane’s recommendations for systematic reviews of diagnostic test accuracy studies were followed. The protocol was registered on PROSPERO. Seven electronic databases were searched up to April 2021. The risk of bias and applicability were assessed using the QUADAS-2 tool. Meta-analysis was not performed. Finally, 13 cross-sectional studies evaluating 3951 patients were analyzed, all of which focused on chronic coronary syndromes defined as anatomically significant coronary stenosis. Invasive coronary angiography was used as a reference in most studies, except one which utilized computed tomography angiography. Sensitivity ranged from 26% to 90%, and specificity from 32% to 96%. Positive likelihood ratios varied from 1.11 to 7.03, but most results were below 2. Negative likelihood ratios were from 0.84 to 0.30, but most values exceeded 0.5. Diagnostic accuracy of diagonal earlobe crease for the detection of chronic coronary syndromes is insufficient. It only slightly changes pre-test probability, and its mere presence or absence should not affect the clinical management of the patients. However, for its feasibility and easy interpretation, Frank’s sign could be considered as a part of physical examination.

Perioperative care and follow-up after bariatric surgery (BS) engage various medical professionals. It is key for them to be well informed about these procedures. However, knowledge and attitudes may be not satisfactory enough to provide proper care. We aimed to assess knowledge and perceptions of BS among diabetologists and internists. A total of 34 diabetologists and 30 internists completed the electronic questionnaire. There were no differences in self-estimated knowledge between them, except regarding items related to the treatment of diabetes and metabolic control. Several misconceptions were identified in the questions testing the understanding of key issues in BS. Most participants considered BS effective in weight loss and metabolic control. A total of 75% highlighted the lack of appropriate equipment for dealing with morbidly obese patients. Interestingly, in a multivariable linear regression model, self-estimated knowledge was the only variable associated with frequency of referrals to bariatric surgeons. A total of 92% of respondents were interested in broadening their knowledge. Guidelines for long-term follow-up and funding were the most frequently chosen topics to explore. The study showed a positive attitude of diabetologists and internists towards surgical treatment of obesity and identified some significant gaps in knowledge. The results may be helpful in planning trainings to provide the best care for patients suffering from morbid obesity.
