RESUMO
BACKGROUND AND AIM: Breech presentation is a condition that occurs in rare cases in pregnancy. Although guidelines recommend a cesarian section or an external cephalic version in case of breech, alternative procedures like acupuncture, are also available. Information on this approach is mostly found by patients through social media; we aimed to study content quality and the reliability of information present on YouTube™ (Google LLC, Mountain View, California, United States), one of the most popular. METHODS: Two gynecologists and an anesthesiologist, who was qualified as an acupuncturist, rated the reliability and the content quality of 23 of the first 100 results from YouTube. Normal data distribution was tested with the Shapiro-Wilk test. General features of videos, reliability, and content quality were compared with the Wilcoxon-Mann-Whitney test (continuous variables) and the Chi-square test (categorical variables). All tests were two-sided, and the statistical significance level was determined at p<0.05. RESULTS: Concerning reliability, all videos were rated poorly while only one was judged as sufficiently high in quality content. Lower scores in terms of reliability and content quality resulted from the reviewers' evaluation with no videos reported as suggestable to patients. Two videos were considered fit to be suggested to patients by the gynecologist reviewers. CONCLUSIONS: Information about the role and the success rate of acupuncture for converting breech presentation found on YouTube are poorly reliable, low-quality, and not valid for patients. It should be a physician's duty to provide correct information to patients.
RESUMO
Diffuse alveolar hemorrhage (DAH) is a clinical condition characterized by the rapid onset of dyspnea, hemoptysis and acute respiratory failure (ARF). It is commonly caused by autoimmune systemic vasculitis, pulmonary infections, drugs and tumors. Here, we report a case of DAH caused by frequent cannabis smoking. A 16-year old boy presented with hemoptysis, dyspnea and ARF soon after laparoscopic surgery for varicocele in general anesthesia. The suspected diagnosis of DAH emerged from the initial chest radiography, and it was then confirmed by CT scan findings and the bronchoalveolar lavage. His general conditions completely recovered after only 24 h of oxygen supplementation and after intravenous corticosteroid and antibiotic therapy. This is the first pediatric case of DAH related to smoking marijuana, even though the inhalational anesthetic agent sevoflurane might have also been involved in this pathogenesis. Other possible causes of DAH have been considered. Negative-pressure pulmonary edema could be ruled out because no clinical evidence of upper airway obstruction was observed during general anesthesia and throughout the surgery. In addition, a possible causative role of cannabis additives/contaminants could not be excluded. Given the high prevalence of cannabis smoking in young people and that DAH can be a complication in cannabis smokers, a careful history and high index of suspicion are recommended as part of the pre-operative assessment before these patients are proceeded to receive general anesthesia.
