Extensive tendon ossification is thought to be rare and is hypothesised to occur due to cell-mediated tissue remodelling. Literature outlining risk factors for the development of an ossified segment, and then a consequent fracture is limited to case reports and case series. A woman in her fifties with a background of several autoimmune disorders presented to a sports and exercise medicine clinic with posterior ankle pain following a bout of brisk walking a month prior. CT and MRI imaging demonstrated a fractured extensively ossified segment of the corresponding Achilles tendon. Conservative treatment was trialled for six months, however, was unsuccessful. Surgical excision of the calcified fragment and flexor hallucis longus tendon transfer were suggested as a potential solution. This case is compared with and builds on current literature surrounding pathophysiology and optimal treatment of extensively ossified segments of the Achilles tendon.

OBJECTIVE: Physical inactivity is a significant contributor to many acute and chronic medical conditions. While the dangers of physical inactivity (PA) are well understood and physicians have the desire to address them, a lack of education in exercise prescription (ERx) may be a barrier to properly prescribing exercise to patients. The aim of this research was to determine the effectiveness of an ERx medical education lecture and provide evidence for the need for formal ERx education among students and physicians in training with a secondary goal of further exploring medical student and resident habits and beliefs about PA and ERx.
METHODS: A one-hour education session was developed based on the American College of Sports Medicine principles of ERx. Pre- and postsurveys were administered immediately before and after the curriculum session to Wayne State University School of Medicine medical students and residents to assess perceived ERx knowledge level and confidence levels for prescribing aerobic and resistance exercise to patients. Virtual curriculum sessions were held over Zoom.
RESULTS: A total of 144 presurvey and 119 postsurvey results were analyzed. The mean perceived ERx knowledge level significantly increased from 4.67/10 ± 1.98 to 7.35/10 ± 1.56 (P < .001). Mean confidence level discussing PA with patients, ability to answer exercise-related questions, confidence level in ability to prescribe aerobic exercise, and ability to prescribe resistance exercise significantly increased in all groups and overall (P < .001).
CONCLUSIONS: A one-hour session to educate medical students and residents on how to write an ERx improved perceived knowledge and confidence in this subject matter. Although further study is needed to determine long-term knowledge retention and the impact on ERx behavioral practice in a patient care setting, this study provides preliminary evidence to justify its inclusion as a regular component of the medical school curriculum.

Acute avulsion fracture of the base of the first metatarsal is a rare occurrence, caused by an eccentric contraction of the peroneus longus tendon insertion. A number of case reports have been published outlining various treatment strategies for treating this rare injury. Management plans range from conservative to operative options and include both acute and delayed operative treatments.We present our operative management strategy of an acute avulsion fracture of the base of the first metatarsal. It includes a step-by-step approach including intraoperative clinical photographs and intraoperative image intensifier images. We explain the rationale behind our operative approach and provide insight on the importance of recognising and treating this injury. Initially, this avulsion fracture might seem innocuous but if left untreated may result in disabling functional foot problems.

McArdle disease is a glycogen storage disease that results in rhabdomyolysis during intense exercise. A number of different triggers have been described. We evaluated a patient with McArdle disease who presented with rhabdomyolysis after recreational scuba diving. There was no concern for barotrauma or decompression sickness. His symptoms resolved with standard-of-care management for non-diving-related rhabdomyolysis. Features of his experience provoked questions about the diving-related factors contributing to his presentation. We present the case and explore possible mechanisms of diving-related injury in patients with McArdle disease, including the possible effects of hyperoxia, hyperbaria, hypothermia and strenuous activity.

Sacral stress fractures (SSFs) in physically active young patients are frequently misdiagnosed due to the lack of specificity of signs and symptoms. Over the last years, these injuries have been described as rare, although some studies report that the incidence of an SSF in athletes may be as high as 20%.We describe a case of a male long-distance runner in his late 20s with a 1-month undiagnosed SSF. The patient complaints included insidious right low back and buttock pain without trauma that started after running a marathon. MRI revealed an extensive area of bone marrow oedema in the right sacral ala consistent with an SSF.This case highlights the importance of investigating SSF in young-athlete patients who were otherwise healthy, using appropriate imaging modalities to assess the presence and morphology of a fracture.

An adolescent female presented to the emergency room with pain, swelling and a palpable lump in the right axilla following activity on a rowing ergometer. The differential diagnosis at the time of presentation was deep vein thrombosis, mass compression and cellulitis. An ultrasound scan revealed an occlusive thrombus of the right axillary and subclavian veins, basilic vein and proximal cephalic vein. The patient underwent pharmacomechanical thrombolysis followed by catheter-directed thrombolysis. Dynamic venogram testing revealed venous thoracic outlet syndrome (VTOS) and a transaxillary first rib resection was performed to decompress the costoclavicular space. Genetic testing revealed the patient was heterozygous for factor V Leiden. Two rounds of balloon dilatation plasty were performed to relieve recurring symptoms due to scarring and persisting compression, 1 and 3 years post rib resection. After extensive shared decision-making, the patient returned to sport, reporting only intermittent symptoms of post-thrombotic syndrome. This case sheds light on the importance of early diagnosis of VTOS for successful return to sport.

We document a case of a transient global amnesia (TGA)-like syndrome following open water swimming. This case was atypical for TGA, in that symptoms were prolonged and ischaemic infarct was considered within the differential. MRI did not demonstrate any changes associated with acute ischaemia although did show a mild degree of small vessel change. With amnesia taking greater than 24 hours to resolve, we have labelled this case to be a TGA-like syndrome, provoked by the commonly reported TGA precipitant of cold water immersion. The possibility of a tiny, strategic infarct causing these symptoms was considered and antiplatelet therapy commenced.

UNASSIGNED: Male amateur marathon runners represent a unique subset of the population who may be at increased risk of cardiovascular disease (CVD) due to their underlying risk factors and their involvement in vigorous exercise such as marathon running.
UNASSIGNED: To assess the modifiable risk factors (MRFs) of CVD in experienced male amateur marathon runners and health interventions on CVD risk factors.
UNASSIGNED: CINAHL, Cochrane Library, Embase, Medline, and SPORTDiscus.
UNASSIGNED: Studies selected according to the inclusion criteria.
UNASSIGNED: Systematic review.
UNASSIGNED: Level 3.
UNASSIGNED: The publication dates included were from June 1, 2008 to February 29, 2020.Published primary epidemiological, observational, randomized controlled trial (RCT) and/or non-RCT studies assessing the MRFs of CVD and health interventions on CVD risk factors in male amateur marathon runners aged ≥18 years and written in the English language were included in the review.
UNASSIGNED: Five studies met the inclusion criteria for analysis. These included male amateur marathon runners (n = 862), aged 42 to 77 years. Hypertension, hyperlipidemia, smoking, and alcohol use were MRFs positively associated with an increased risk of coronary atherosclerosis found in a subset of male marathon runners. No studies examined health interventions on CVD risk factors in any of the included studies. All 5 studies were of good quality from the National Heart, Lung, and Blood Institute quality assessment tools used. The risk of bias was low to moderate.
UNASSIGNED: There is a paucity of observational studies evaluating the CVD MRFs. Negative lifestyle behaviors exist within this population despite their engagement in physical exercise through marathon running. Marathon running does not negate the long-term effects caused by past negative lifestyle behaviors. This systematic review identifies that this population may not be aware of their possible risk of atherosclerosis and, consequently, CVD.
