Length of Recovery From Sports-Related Concussions in Pediatric Patients Treated at Concussion Clinics
Conclusions: High symptom scores at injury and initial visit, time to initial clinical presentation, presence of 2 or more previous concussions, and female sex are associated with prolonged concussion recovery. Further research should aim to establish objective measures of recovery, accounting for treatment received during the recovery. Clinical Relevance: The median length of recovery is 17 days among pediatric sports–related concussion patients treated at concussion clinics. Only 16.3% of patients recovered within one week, whereas 26.4% took longer than 4 weeks to recover. (Source: Clinical Journal of Sport Medicine)

First-Aid Treatment for Friction Blisters: “Walking Into the Right Direction?”
Conclusions: Wide area fixation dressing decreased time of treatment application by 2 minutes (4.5%) when compared with adhesive tape. However, because of lower effectiveness and a trend toward lower satisfaction, we do not recommend the use of wide area fixation dressing over adhesive tape in routine first-aid treatment for friction blisters.

Bilateral Anterior Knee Pain in a High School Cross-Country Runner: An Atypical Etiology
Abstract: Anterior knee pain is a common complaint found in distance runners, and can be the end result of a variety of benign processes. A 17-year-old female cross-country runner presented to a sports medicine clinic with insidious onset of bilateral patellofemoral pain (PFP). In the workup of the significant quadriceps weakness discovered on her initial examination, a principal contributing cause of her PFP, she was found to have a form of spinal muscular atrophy, an uncommon neurodegenerative disease that typically requires multidisciplinary medical care. Her case provides a good example for clinicians to consider, at t...

Abdominal Aortic Dissection and Cold-Intolerance After Whole-Body Cryotherapy: A Case Report
We present the case of a 56-year-old patient who developed an abdominal aortic dissection after receiving 15 sessions of WBC. The patient had no other strong risk factors for aortic dissection. Exposure to cold temperatures, including WBC, has multiple hemodynamic effects, including increases in blood pressure, heart rate, and an adrenergic response. We suggest that these changes could act as a trigger for the onset of aortic dissections. This could be the first reported cardiovascular complication associated with WBC.

Trunk Muscle Function Deficit in Youth Baseball Pitchers With Excessive Contralateral Trunk Tilt During Pitching
Conclusions: Excessive CLT may be a strategy that young pitchers learn to achieve higher ball velocity but also may be associated with imbalance between the oblique muscles on dominant and nondominant side, which may be acquired from repetitive pitching. Strengthening and emphasizing the use of dominant side oblique muscles may keep pitchers from leaning excessively during pitching and thus decrease joint loading.

Early Screening for Cardiovascular Abnormalities With Preparticipation Echocardiography: Feasibility Study
Objective: The traditional history and physical (H&P) is a poor screening modality to identify athletes at risk for sudden cardiac death. Although better than H&P alone, electrocardiograms (ECG) have also been found to have high false-positive rates. A limited portable echocardiogram by a frontline physician (PEFP) performed during preparticipation physical examination (PPE) allows for direct measurements of the heart to more accurately identify athletes with structural abnormalities. Therefore, it is worthwhile to assess the feasibility of incorporating limited PEFP as part of PPEs. The aim of this study was to in...

Triple Fracture of the Intra-Articular Second Metacarpal Head, Intra-Articular Fourth Metacarpal Base, and Ulnar Styloid of An Ice Hockey Player: A Case Report
We present a case of simultaneous ipsilateral fractures at the intra-articular second metacarpal head, intra-articular fourth metacarpal base, and ulnar styloid. These fractures were caused by the peculiar condition of a blow to the fist during an ice hockey game; the hand was struck while it was gripping a stick. The specific combination of these fractures has not been previously reported in the literature.

To the best of our knowledge, this is the only report of partial ECU subluxation due to a split in the ECU tendon presented in the literature. This case illustrates the importance of proper diagnosis and treatment of such a lesion. We also emphasize that dynamic ultrasound is an excellent and cost-effective imaging modality that can help with the diagnosis of partial ECU subluxation.
