RESUMO
Anatomy Academy is a simultaneous service-learning experience for preprofessional school undergraduate students and preclinical professional students acting as classroom paraprofessional teachers (Mentors), and engaged-learning experience for fourth to sixth grade elementary school children (Students). Using didactic and kinesthetic active learning teaching strategies in small-group classroom environments, Mentors taught anatomy, physiology, and nutrition concepts to Students. In this study of the program's early years (2012-2014), overall objectives of improving Mentors' pedagogical confidence; and Students' science interest, science knowledge, and exercise self-efficacy were assessed. Mentors showed (89% response of 595 surveyed) improvement in content delivery (P < .001), student engagement (P < .001), classroom management (P < .001), and professionalism (P = .0001). Postprogram Mentor reflections were categorized into 7 major themes that demonstrated personal growth through the service-learning opportunity: (1) realization of an ability to make a difference in the world now; (2) acknowledgment of the importance of listening in teaching; (3) recognition that lives can and will change with "a little love"; (4) insight into the effectiveness of guiding Students through material rather than lecturing; (5) awareness of the value of respect in the learning environment; (6) cognizance of the power of individualized attention to motivate Students; and (7) reflection of one's own personal growth through the open influence of Students. Students showed (88% response of 1259 surveyed) improvement in science knowledge (P = .014) and exercise self-efficacy (P = .038), but not science interest (P = .371). Thus, while Students are learning more science and becoming more aware of their health, we need to be more overt in our presence as scientists in the educational arena.
RESUMO
Background: Open reduction and internal fixation (ORIF) methods, primarily plates and screws, remain the standard of treatment for distal fibular fractures. This study evaluates the use of a cannulated intramedullary screw as a minimally invasive treatment method for distal fibular fractures, which has not been reported in the current literature. Methods: This retrospective study included 45 patients with distal fibular fractures treated with cannulated intramedullary screw fixation. All patients included in the cohort had a soft-tissue condition and/or comorbidity. The mean age was 54 years. The Weber classification system was used to assess the type of fracture. Average time to union, average time to weight bearing, and complications were monitored. Results: Reduction quality criteria were collected using previously published guidelines. Accordingly, reduction was determined to be good in 25 cases, fair in 15, and poor in 5. A low complication rate of 4% was reported. Average time to union was 10 weeks (range = 8-36 weeks), whereas average time to weight bearing was 14 weeks (range = 8-40 weeks). Conclusion: Cannulated intramedullary screw fixation can serve as a minimally invasive, safe, and satisfactory treatment for distal fibular fractures with resulting high union rates and low complication rates. Levels of Evidence: Level IV: Retrospective, case series.

BACKGROUND: Ankle fractures involving syndesmosis disruption cause severely unstable joint conditions. Traditional invasive operations put certain patient groups at an increased risk of infection. There is limited literature discussing the outcomes of minimally invasive fixation of severe ankle fractures including syndesmotic injury, as clinicians may be tempted to treat these difficult cases with open reduction internal fixation (ORIF). METHODS: A retrospective case-control study was conducted on patients treated at a level one trauma center. Patients were divided into 2 groups based on presence of diabetes and/or obesity (body mass index ≥30.0 kg/m2). Those with either comorbidity were defined as high infection risk patients and placed in a comorbidity group. Patients were further divided into subgroups based on the operation's invasiveness; either traditional ORIF or percutaneous cannulated screw fixation. RESULTS: Comorbid patients (N = 67) were more likely to sustain Weber C fractures compared to noncomorbid patients (N = 43) (59.70% to 37.21%, P = .019). Additionally, patients receiving minimally invasive fixation procedures experienced fewer infections than those receiving ORIF (0 vs 11 incidences, P = .01), without effect on union rates, fracture reduction, pain, need for revision surgery, or time to full weightbearing. CONCLUSIONS: Diabetic and obese patients are at an increased risk of experiencing severe ankle fractures. The use of minimally invasive fixation methods can reduce the risk of postoperative infection without sacrificing other surgical outcomes, even with fractures involving syndesmotic injury. LEVELS OF EVIDENCE: Therapeutic, Level III: Retrospective comparative study.

Superficial CD34-positive fibroblastic tumor is a low-grade mesenchymal neoplasm of superficial soft tissues characterized by fascicles of spindle to epithelioid cells displaying nuclear pleomorphism and strong diffuse CD34 immunoreactivity. The intraoperative imprint cytology preparations (ICP) of a superficial CD34-positive fibroblastic tumor from a 50-year-old female are described. To the best of our knowledge, there is no report of the cytologic findings of superficial CD34-positive fibroblastic tumor in the English medical literature. The ICP, differential diagnosis, tissue correlation, and ancillary studies of this fascinating entity are discussed. Diagn. Cytopathol. 2016;44:926-930. © 2016 Wiley Periodicals, Inc.

BACKGROUND: The role of each surgical approach on the outcomes of pilon fractures has not been investigated in a systematic review. METHODS: This systematic review was conducted with a thorough literature search on PubMed using the keywords ("pilon" OR "plafond") "fracture." Only articles written in the English language that have been published within the past 15 years and discussed the surgical approach were considered. RESULTS: A total of 733 patients were included in this review. All the fractures were either OTA Type B or C fractures: 157 were Type B and 576 were Type C. Anterior and medial approaches have some of the best results in the literature with respect to complication rate. The posterolateral and anteromedial approaches have markedly higher complication rates. CONCLUSIONS: The anterolateral group had the largest number of patients-comprising one third of the entire study population. The anterior approach had one of the lowest complication rates with a patient base that had a high proportion of OTA Type C fractures. The medial approach produced a low complication rate over a larger patient base that had a higher proportion of OTA Type B fractures. LEVELS OF EVIDENCE: Therapeutic, Level IV: Systematic review.
