RESUMO
INTRODUCTION: Despite the potential of social media to influence public health and generate insights, the process of monitoring and analyzing the dissemination of health care messages on social media has been described as difficult and in need of improvement. OBJECTIVES: The objective of this study was to describe and demonstrate a reproducible methodology for cataloging and analyzing health care-related social media comments and provide insight into how clinicians and members of the general public respond to health care messaging on social media. METHODS: We collected social media comments related to the American Dental Association's 2016 "Evidence-Based Clinical Practice Guideline for the Use of Pit-and-Fissure Sealants" between April 10, 2017, and October 31, 2017, from Facebook, Twitter, LinkedIn, Reddit, and online message boards for the New York Times, FiveThirtyEight, and Dentaltown. Using data provided in the comments, we conducted engagement analysis as well as content, network, and sentiment analysis across 8 categories. RESULTS: We collected 671 comments. Among our findings, Facebook (472 of 671) was the most popular platform among commentators; almost half of all comments (335 of 671) aligned with the recommendations of the 2016 American Dental Association sealants guideline; clinicians were more likely than the general public to like a comment that suggested an improvement to the guideline; and >75% of comments (521 of 671) were supported by anecdotal evidence. CONCLUSION: As the prevalence of anecdotes on social media suggests, the likelihood of falsehoods spreading on social media is high. Insights gleaned from the methodology described in this research could help combat the spread of such misinformation by providing disseminators of health care messaging with insight into their target audiences. Armed with this knowledge, disseminators can craft health care messages that more effectively engage clinicians and the general public. KNOWLEDGE TRANSFER STATEMENT: The methodology used in this research provides a reproducible strategy for tracking social media engagement with health care messages. Engagement results can assist future delivery of health care messages to key stakeholders and ensure better implementation and adoption of these communications.

An analogy based on the likenesses of the APH-6 aviator's protective helmet and the hangman's noose has some interesting relationships to aircraft accident investigation and to the associated traumatic pathology. A superficial examination of the similarities might propose that the inferior edge of the helmet, when considered part of the continuous circle completed by the nape strap and the chin strap, forms a loop which can be likened to a hangman's noose. The analogy might be extended to the comparison of lesions made about the neck by the straps or the edge of the helmet compared with abrasions and contusions that might be associated with a rope encircling the same structures. Such a hangman's noose, when the knot is at the side of the head (subaural), produces fractures of the base of the skull tending to extend bitemporally through the basisphenoid. When the knot is anterior and beneath the chin (submental), the hangman's noose causes a fracture dislocation at the axis. Characteristically, the posterior arch is fractured and, interestingly enough, the odontoid process is not involved. Many of us anticipate that a fractured, displaced odontoid process is the prototype lesion which so precariously endangers the patient with cervical cord compromise and death similar to the hangman's fracture. More recent assessments of the mortality of the odontoid fracture suggest less than 10%.

Laparoscopic deroofing of the solitary non parasitic cysts of the liver is a safe and effective procedure. This technique allows a wide access for surgical treatment of cysts localized in segments II, III, IVb, V, and VIII of the liver. On the contrary, the posterior segments, VI and VII, and the segment IVa, are difficult to approach laparoscopically. This report describes a laparoscopic technique used in treating 3 cases of symptomatic solitary cysts of the posterior segments of the liver. The patients were placed in the left lateral position. The fenestration treatment was easy and the mobilization of the right hepatic lobe was not required. At one year follow-up, neither postoperative complications nor recurring episodes were observed.

BACKGROUND: This study aimed to compare the safety, efficacy and clinical benefits of laparoscopic splenectomy (LS) to open splenectomy (OS) in patients with hematologic disorders. EXPERIMENTAL DESIGN: prospective study; SETTING: II Department of Surgery, Santa Maria Nuova Hospital, Reggio Emilia and III Department of Surgery, Santo Spirito Hospital Pescara; PATIENTS: 48 consecutive adult patients underwent splenectomy; 30 patients under-went LS and 18 OS. Perioperative characteristics, outcomes, complications and costs were comparatively analyzed. RESULTS: Mean age was 35.3 years in the LS group, and 40.8 in the OS group. Mean spleen size was 11.7 cm in the LS group and 15.2 cm in the OS group. Accessory spleens were found in 5 patients in the LS group and in 4 patients in the OS group; 4 conversions to laparotomy occurred in the LS group. A total of 4 complications occurred in 3 patients of the LS; 9 complications occurred in 5 patients of OS group. Mean surgical time was 141.5 minutes for LS and 89.7 minutes for OS (p<0.005). Mean postsurgical stay was 5.8 days in the LS group and 8.5 days in the OS group (p<0.005). Response rates were similar in both groups. CONCLUSIONS: LS is comparable to OS in terms of efficacy and safety and it is associated with a shorter hospital stay. LS should become the technique of choice for treatment of intractable benign hematologic disease.

Plasma renin activity (PRA) and plasma aldosterone concentrations (PAC) were determined in fifty normal newborns during the first 72 h of life. PRA was elevated in all cases and tends to increase from the first (6.79 +/- 0.69SE ng/ml/h) to the third day of life (8.24 +/- 0.96SE ng/ml/h). PAC was also elevated and rose from 24.06 +/- 3.23SE ng/dl on the first day to 39.20 +/- 4.25SE ng/dl on the third day. No significant correlation was observed between PRA and PAC. Serum sodium was within the normal range, whereas serum potassium was slightly elevated during the first 48 h of life. The physiological significance of the high levels of PRA and PAC in newborns is not clear at present. Many factors may be involved in the increased activation of the renin-angiotensin-aldosterone system: low blood pressure, hypersensitivity of the macula densa to catecholamines, relative insensitivity of the immature kidney to aldosterone, hyperkalaemia and other control mechanisms for aldosterone secretion all of which probably operate simultaneously during the first days of life.
