Chest-to-arm (CTA) tunneling has been described recently as a technique that allows an optimal exit site at mid-arm even in chronically ill patients with complex clinical issues and challenging problems of vascular access.
We adopted CTA tunneling in oncologic and in non-oncologic patients, in totally implanted and in external devices, for both medium and long-term intravenous treatments. We report our experience with 60 cases of CTA tunneling 19 patients requiring a totally implantable device, who had bilateral contraindication to venous access at the arm and bilateral contraindication to placement of the pocket in the infra-clavicular area; 41 patients requiring an external central venous catheter, who had bilateral contraindication to insertion of peripherally inserted central catheters or femoral catheters, as well as contraindication to an exit site in the infraclavicular area. All venous access devices were inserted with ultrasound guidance and tip location by intracavitary electrocardiography, under local anesthesia.
There were no immediate or early complications. Patients with CTA-ports had no late complications. In patients with CTA-tunneled external catheters, there were two dislodgments, four episodes of central line associated blood stream infections, and one local infection. There were no episodes of venous thrombosis or catheter malfunction.
Our experience suggests that CTA tunneling is a safe maneuver, with very low risk of complications, and should be considered as an option in patients with complex venous access.

Our study explored how individual differences in personality and communication styles affect the evaluation of literal and nonliteral language in the context of assumptions made by the Tinge Hypothesis (Dews & Winner, 1995). Participants watched videos of social interactions focusing on positive, negative, sarcastic, and jocular statements. They evaluated speaker intentions and social impressions and completed several personality and communication style questionnaires. Individual differences in empathy, defense style, and sarcasm use correlated with the accuracy of identifying speaker intent. Additionally, positive statements were rated as friendlier when compared to jocular statements, thereby supporting the Tinge Hypothesis. However, literal negative statements were rated as more friendly than sarcastic statements, which is inconsistent with the Tinge Hypothesis. The current results provide novel evidence for the Tinge Hypothesis using multimodal, dynamic stimuli and highlight the role of the individual personality of the recipient in evaluating sarcasm and jocularity.
Cannulation of the radial artery can be extremely challenging in infants. Scale ultrasound can provide accurate arterial location and guidance for operators. We hypothesized that scale ultrasound helps increase the initial success rate of radial artery cannulation in this population.
Seventy-six infants aged 0-3 months who needed arterial puncture after general anesthesia were randomly divided into two groups (11 ratio) the scale ultrasound group and the traditional ultrasound group. The primary endpoints were the success rate of the first attempt and the total success rate of arterial cannulation. The secondary endpoints were the time during arterial puncture and the incidence of vascular complications.
The success rate of the first attempt and the total success rate of arterial cannulation were 92.1% (35/38) versus 50% (19/38) and 100% (38/38) versus 86.8% (33/38) in the scale ultrasound and traditional ultrasound group (
< 0.005), respectively. The median time to ultrasound location, needle entry into the radial artery, and successful cannulation in the scale ultrasound group were significantly shorter than those in the traditional ultrasound group 10 (8.0, 17.2) s, 15 (11.7, 20) s, and 65 (53.8, 78.5) s vs 30 (26.5, 43.5) s, 35 (23, 51) s, and 224.5 (123.5, 356) s (
< 0.001), respectively. The incidence of hematoma was higher in the traditional group (
< 0.005).
Scale ultrasound-guided radial arterial cannulation can significantly improved initial success rate and overall success rate, shorten puncture time in infant, compared with that achieved with the use of traditional ultrasound guidance.

This study aimed to review level I and II therapeutic studies on boxer's fractures to measure variation in quality among the highest level study designs.
We used quantitative measures of study quality to evaluate prospective randomized controlled trials (RCTs) of treatments of boxer's fractures. A search of PubMed, using terms "boxer's fracture" and "fifth metacarpal neck fracture" identified 164 articles from 1961 to 2019. From this list, we identified 6 RCTs. Calpeptin Two observers classified each trial according to 3 systems the Oxford Levels of Evidence, the modified Coleman Methodology Score, and the revised Consolidated Standards of Reporting Trials (CONSORT) score.
The 2 reviewers were consistent in their use of the Oxford Levels of Evidence (100% agreement). The differences between the average modified Coleman Methodology scores and the average CONSORT scores assigned by the 2 observers were not significant (46.2 vs 45.3 points, κ = 0) and (13.7 vs 14.3 points, κ = 0.33), respectively. Both observers rated all the studies as level I and as unsatisfactory according to the Coleman Methodology Score (100% and 100%), and less than half as unsatisfactory according to the CONSORT score (50% and 17%). Areas of deficiency included randomization, blinding, group comparability, clinical effect measurements, and allocation into treatment arms.
Classifying orthopedic scientific reports according to the levels of evidence implies a degree of respect for level I and II studies that may not always be merited. Our data suggest that the quality of higher level studies, namely those involving boxer's fractures, varies and may often be unsatisfactory when critically evaluated.
