Setting, Structure, and Timing of the Preparticipation Examination: The Wilderness Adventure Consultation
This article outlines the goals of the PPE along with identification of various risk factors that can influence a trip. Most injuries and rescues occur from underestimating the risks from extrinsic, environmental factors, and/or overestimating one's intrinsic skills. By matching the patient's fitness and skill level to the environment, the physician can help reduce the risk of serious injury. (Source: Clinical Journal of Sport Medicine)

Lateral Pectoral Nerve Injury Mimicking Cervical Radiculopathy
Abstract: The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are rare. Here, we present a case of an isolated LPN lesion confused with cervical radiculopathy. A 41-year-old man was admitted to our clinic because of weakness in his right arm. Previous magnetic resonance imaging (MRI) examination revealed right posterolateral protrusion at the C6-7 level. At the initial assessment, atrophy of the right pectoralis major muscle was evident, and mild weakness of the right shoulder adductor, internal rotator, and flexor muscles was observed. Therefore, electrodiagnostic ...

Baseline SCAT2 Assessment of Healthy Youth Student-Athletes: Preliminary Evidence for the Use of the Child-SCAT3 in Children Younger Than 13 Years
Conclusions: Normative values for total SCAT2 and subscale scores show differences in concentration between ages, whereas symptoms, BESS, and immediate memory differed between sexes. We also found that 12 year olds have increased difficultly with the advanced concentration tasks, which lends support to the development of a separate instrument, such as the Child-SCAT3. The presence of developmental differences in the younger age groups suggests the need for annual baseline testing. Clinical Relevance: Subtle differences between age and sex have been identified in many components of the SCAT2 assessment. These differences ma...

Body Weight, Serum Sodium Levels, and Renal Function in an Ultra-Distance Mountain Run
Conclusions: There was a 2% incidence of EAH in this study. Serum [Na] change during an 85-km mountain run was inversely correlated with the volume of fluid consumed. The results provide further evidence that EAH is a dilutional hyponatremia caused by excessive consumption of hypotonic fluids. Drinking to thirst represents a safe hydration strategy for runners in a wilderness environment. Clinical Relevance: Drinking to thirst during endurance running events should be promoted as a safe hydration practice. (Source: Clinical Journal of Sport Medicine)

Concussion Management in Collegiate Student-Athletes: Return-To-Academics Recommendations
Abstract: Concussions in collegiate athletics can affect student-athletes both on the field and in the classroom. As policies are made to outline return-to-play decisions and timelines, this article will make the case that return-to-academics should also be included and follow a step-wise protocol. Complete cognitive rest is a cornerstone of concussion recovery and slow reintroduction to academics should precede return-to-play. The college structure allows for student-athletes to begin small doses of cognitive activity after the recommended complete cognitive rest. It is recommended that return-to-academics involves a team...

Brain or Strain? Symptoms Alone Do Not Distinguish Physiologic Concussion From Cervical/Vestibular Injury
Conclusions: Symptoms after head injury, including cognitive symptoms, have traditionally been ascribed to brain injury, but they do not reliably discriminate between physiologic PCD and cervicogenic/vestibular PCD. Clinicians should consider specific testing of exercise tolerance and perform a physical examination of the cervical spine and the vestibular/ocular systems to determine the etiology of postconcussion symptoms. Clinical Relevance: Symptoms after head injury, including cognitive symptoms, do not discriminate between concussion and cervical/vestibular injury. (Source: Clinical Journal of Sport Medicine)
