Acute renal infarction (ARI) is a rare condition associated with poor prognosis in most cases. Due to non-specific clinical symptoms and abnormalities in lab results, as well as equivocal results of imagining scans, diagnosis of ARI is often delayed. Anabolic-androgenic steroids (AAS) intake in contribution to heavy weight-lifting workout are among the risk factors for hypercoagulable state. AAS are responsible for a number of haemostatic defects, including higher platelet number, enhanced platelet aggregation, increased synthesis of procoagulant factors and impaired fibrinolysis. Increasing number of AAS intake among amateur and professional athletes observed in recent years require consideration of these drugs as possible cause for thrombotic events in young patients. Yet, only few case studies have been published describing an occurrence of venous or artery thrombosis in athletes who had been using anabolic steroids. In this case report, authors present a case of right renal artery thrombosis in a 34-old bodybuilder who had been using unknown anabolic steroids to increase his performance. Due to bleeding complications after selective intra-arterial thrombolysis treatment, he required urgent nephrectomy and was released from hospital with significantly elevated azotemia parameters. This highlights the importance of careful medical history being taken with respect to AAS and illicit drug abuse for the prevention and fast, accurate diagnosis of thrombotic episodes in young athletic patients.

We report a case of a 14-year-old soccer player with Iselin’s disease. Iselin’s disease is a benign adolescent growth disturbance, called apophysitis, of the base of the fifth metatarsal caused by traction of the m. peroneus brevis tendon. This type of apophysitis is extremely rare. A review of the literature revealed only 17 cases of Iselin’s disease. The diagnosis can be confirmed by radiographic features. A review of the literature offers a better comprehension of clinical and radiographic characteristics, differential diagnosis, treatment and prognosis of Iselin’s disease.

Background: An ankle sprain is a very common sport-related injury and can reduce participation in sports and employment. It can also create further complications in the function of the joint.

Purpose: To evaluate the effectiveness of different functional treatments and to ascertain which functional treatment is the most effective method for acute ankle sprains.

Study Design: Systematic review.

Methods: The design of this systematic review was developed in accordance with PRISMA-P 2015 statement and performed according to its guidelines. A computerized literature search was performed from PubMed Central, MEDLINE via OVID and Cochrane library. Randomized controlled trials or quasi-experimental studies, published within a ten-year period (2007 to 2017), in peer-reviewed journals, with full-text articles and written in English were included in this study. Any type of functional treatments being applied to treat acute ankle sprains were considered as an intervention and only adult participants were included in this review. Surgical methods, unpublished trials, not written in the English language or not experimental research were excluded.

Results: From the pooled data of this review, the stocking was more effective at improving pain, swelling, functional outcomes, range of motion, and return to sport/work, and had higher patient satisfaction than the bandage. There was no evidence that the taping and lace-up brace were more effective than other functional interventions in the treatment of acute ankle sprains. Furthermore, the prevalence of complications was greatest for the taping and lace-up brace interventions. The semi-rigid or posterior rigid support group had a better functional recovery and higher patient satisfaction, but some complications were present.

Conclusion: The semi-rigid or posterior rigid support group and stocking were the most effective functional interventions for acute ankle sprain treatment.

What is known about this subject: The functional treatments are becoming popular due to being effective, inexpensive and simplistic to apply. Different types of functional interventions have been used according to the choice of clinicians and patients in the treatment of ankle sprains. According to the previous researches, semi-rigid support, ankle braces, bandage and lace-up supports have greater advantages than other functional treatments from different perspectives (Example. the elastic bandage had a slower recovery rate than semi-rigid brace but less complications than taping, the lace-up support was better in swelling management than other functional treatments).

What this study adds to existing knowledge: This study found that the stocking is an effective treatment for managing acute ankle sprains. It is valuable for the patient because the cost of the stocking is considerably cheaper than other functional treatments and it is very easy to wear. Some popular functional treatments like lace-up support; taping and semi-rigid braces were shown to have some complications.

Objective: In the Australian Football League (AFL) an injury is only recorded when it causes a player to miss a match. This recording method indicates a predominance of lower limb injuries, although the Victorian Injury Surveillance Unit has shown the upper limb to be involved almost twice as commonly as the lower limb. We hypothesize that hand, finger and wrist injuries in AF are an under-recognized entity due to the ability of players to continue play without missing subsequent games. The aim of this study is to estimate the true incidence of hand, finger and wrist injuries in elite AF players, through a prospective study of all hand, finger and wrist injuries at a professional AFL club during an entire season.
Methods: This is a prospective cohort study of all senior and rookie players at an AFL club examining the incidence and epidemiology of hand, finger and wrist injuries during the 2015 AFL season.
Results: An incidence of 25.0 injuries per season requiring treatment in 27 players was recorded during the 2015 AFL schedule. A total of two games were missed due to metacarpal fracture. All other players continued to play with their injury during the season with three players requiring surgery post season. A hand, finger and wrist injury incidence of 43.8 per 1000 exposures was recorded, equating to 22.6 injuries per 1000 contact hours.
Conclusion: Hand, finger and wrist injuries in AF are an under-recognized entity due to the ability of players to continue play without missing subsequent games. This study highlights a tendency to minimize the impact of hand, finger and wrist injuries within AF and the scientific literature, and raises further questions regarding injury reporting and management within professional sports. We recommend the adoption of more detailed

Objective: This study aimed to conduct a survey of coaches of youth athletes (e.g. middle school, high school, and university students) on the current state of and their attitudes towards anti-doping education, and on their level of familiarity with sports pharmacists (pharmacists with specialized knowledge on doping). A secondary aim was to examine the future directions of anti-doping education, including the roles of sports coaches and points at which they may intervene to resolve these issues.
Methods: Sports coaches who taught health and physical education or coached extracurricular activities were asked to complete a questionnaire. In addition to general information such as the respondent’s age, their affiliated educational organization, number of years’ experience of teaching and/or coaching, the types of sports they were involved in, and their level of athletic competition, data were collected on participants’ experience with anti-doping education, their degree of familiarity with sport pharmacists, and their attitudes concerning the necessity of antidoping education and sports pharmacists.
Results: Responses were obtained from 211 coaches. In response to a question that asked about their level of familiarity with sports pharmacists, 62.1% of the respondents said that they did not know of this profession. In response to a question on whether or not they had experience conducting classes on anti-doping, only 32.6% of coaches (n=31) said that they had such experience. On the other hand, responses to a question that asked about the necessity of anti-doping lectures showed that over 90% of coaches felt that they were needed. Furthermore, in response to questions on whether or not they would like to make use of antidoping teaching materials, should they be available, approximately 90% of coaches said that they would.
Conclusion: Although coaches of youth athletes recognize the importance of anti-doping education, only a few coaches actually deliver such education. The results also revealed that coaches’ level of familiarity with sports pharmacists was low. In the future, activities aiming to disseminate knowledge on anti-doping practices, not only to athletes but also to their coaches, will be necessary; these could include measures such as holding seminars and developing anti-doping teaching materials.
