Langerhans Cell Histiocytosis Presenting as a Lesser Trochanter Fracture in an Adolescent: A Case Report.

Case: We present the case of an 18-year-old man with right hip pain who was found to have a lytic lesion of the lesser trochanter of the right femur with cortical destruction and a lytic lesion of the left inferior pubic ramus. Additional imaging and pathology testing confirmed a diagnosis of multifocal, single-system Langerhans cell histiocytosis (LCH) of the bone.

Conclusion: LCH is a rare pediatric disease most commonly diagnosed in toddlers and young school-age children.

Resistance Training for Children and Adolescents.

Resistance training is becoming more important as an integral part of comprehensive sport training regimens, school physical education classes, and after-school fitness programs. The increasing number of youth who are involved in sport activities, coupled with the health problems of inactivity and being overweight, have resulted in increased interest in resistance training. Secular declines in measures of muscular fitness in modern-day youth highlight the need for participation in youth resistance training for nonathletes as well as athletes.

Preliminary Use of the Physical and Neurological Examination of Subtle Signs for Detecting Subtle Motor Signs in Adolescents With Sport-Related Concussion.

Sensitive examination tools are needed to optimize evaluation after sports-related concussion. The Physical and Neurological Examination of Subtle Signs was preliminarily examined for sensitivity to motor changes in a pilot cohort of adolescents aged 13-17 yrs with sports-related concussion. A total of 15 adolescents (5 female adolescents) with sports-related concussion were evaluated up to three times: within 2 wks of injury, approximately 1 mo later (mean, 35 days between visits), and for those not recovered at the second visit, again after clinical recovery (mean, 70 days between the first and last visits for all participants).

Proximal Radial Head Fractures in Young Gymnasts: A Case Series of Newly Described Overuse Injuries.

We report a case series of unilateral Salter-Harris IV fractures of the proximal radial heads in young female gymnasts. To date, there are no previous reports of such injuries in gymnastics. In all 3 athletes, no significant injury preceded presentation or diagnosis.

Epidemiology of Injuries in Women's Lacrosse: Implications for Sport-, Level-, and Sex-Specific Injury Prevention Strategies.

Objective: By the end of 2013, the United States had an estimated 278 000 female lacrosse players, with half of those participating at the youth level. The effects of the sport's rapid growth on injury rates have yet to be determined. The purpose of this clinical review is to synthesize the available published data on injuries that have occurred in the sport of women's lacrosse.

Epidemiology of injuries in men's lacrosse: injury prevention implications for competition level, type of play, and player position.

Objective: The growth in participation in men's lacrosse has increased the likelihood of sport-specific injuries, yet there continues to be a need for specific epidemiological data concerning lacrosse injuries. The purpose of this literature review is to aggregate available published data on injuries that occur in the sport of men's lacrosse at the youth, high school, collegiate, and professional levels.

Methods: A comprehensive literature search was performed in PubMed, High Wire Press, SPORTDiscus, Google Scholar, and Ovid, using the keywords Lacrosse Injuries, Epidemiology Lacrosse Injuries, Lacrosse Injury, Lacrosse AND Injury and limited to 1990-2016.

Amenorrhea in the Female Athlete: What to Do and When to Worry.

Functional hypothalamic amenorrhea is a diagnosis of exclusion that is common in female athletes, particularly those participating in aesthetic sports (ballet, other dance genres, figure skating, and gymnastics) and endurance sports (cross-country running). Although common, it should be considered abnormal even in the high-level elite athlete. Amenorrhea in combination with low energy availability and low bone density is labeled "the Female Athlete Triad.

Position statement on youth resistance training: the 2014 International Consensus.

The current manuscript has been adapted from the official position statement of the UK Strength and Conditioning Association on youth resistance training. It has subsequently been reviewed and endorsed by leading professional organisations within the fields of sports medicine, exercise science and paediatrics. The authorship team for this article was selected from the fields of paediatric exercise science, paediatric medicine, physical education, strength and conditioning and sports medicine.

Injury initiates unfavourable weight gain and obesity markers in youth.

Objective: The purpose of this study was to examine the association of knee injuries with subsequent changes in body mass index and body composition during maturation in young females.

Methods: A prospective longitudinal study design was employed to evaluate young females active in soccer or basketball (N=862). Participants who completed at least 1-year follow-up to provide consecutive annual measures of BMIZ and %fat were included in the study analysis to determine the effect of knee injuries on the trajectory of these obesity markers in youth.

Case report: bilateral proximal epiphyseal clavicular stress-related lesions in a male gymnast.

Background: Stress lesions of the upper extremity are relatively uncommon, and physeal stress lesions of the clavicle are rare. We present a case of bilateral physeal stress-related lesions of the proximal clavicular growth plate near the sternoclavicular joint in an adolescent male gymnast.

Case Description: A 13-year-old gymnast presented with a 3-week history of insidious onset of pain in the proximal clavicular area of his left shoulder.

Athletic participation by children and adolescents who have systemic hypertension.

Children and adolescents who have hypertension may be at risk for complications when exercise causes their blood pressure to rise even higher. The purpose of this statement is to update recommendations concerning the athletic participation of individuals with hypertension, including special populations such as those with spinal cord injuries or obesity, by using the guidelines from "The 36th Bethesda Conference: Eligibility Recommendations for Competitive Athletes with Cardiovascular Abnormalities"; "The Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents"; and "The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure."

Strength training in children and adolescents: raising the bar for young athletes?

Context: Strength training in children, in combination with plyometric and/or agility training, has become an increasingly popular tactic for athletes to gain a competitive edge during the off-season. The present review clarifies some common myths associated with strength training in children, and it outlines the most current recommendations.

Evidence Acquisition: Relevant studies on strength training in children and adolescents were reviewed (search results included studies indexed in PubMed and MEDLINE from 1980 through 2008).

Strength training by children and adolescents.

Pediatricians are often asked to give advice on the safety and efficacy of strength-training programs for children and adolescents. This statement, which is a revision of a previous American Academy of Pediatrics policy statement, defines relevant terminology and provides current information on risks and benefits of strength training for children and adolescents.
