Thorough writeup on work risks at postharvest wheat operations.
DCO diagnosis should be considered in cases with unresolving shoulder pain.
DCO can be difficult to diagnose given its limited etiological understanding, low incidence, and poor radiographic sensitivity. DCO diagnosis should be considered in cases with unresolving shoulder pain.
This study describes the radiographic diagnosis and nonoperative chiropractic management for a case of a chronic calcaneonavicular coalition in an adult patient.

Calcaneonavicular coalition is a congenital/acquired condition of the tarsal bones often diagnosed in individuals 8-12 years old. Considering its rare presentation (less than 1% of the population), there remains little literature on the conservative management of this condition.

Chronic calcaneonavicular coalition in a 35-year-old recreational athlete is presented.

Following radiographic diagnosis, the patient was placed in a walking boot for four-weeks. After removal of the boot, the patient was managed nonoperatively. They reported a full resolution of symptoms with noted return to all pre-injury activities.

Presentation of calcaneonavicular coalition may be dependent on many factors, including age, medical history, and chronicity of the condition. Previous medical background may include recurrent inversion ankle sprains, aggravated with activity, and alleviated with rest. Nonoperative management of calcaneonavicular coalition may be considered as a viable intervention.

To present the diagnostic, clinical, and radiological features of pigmented villonodular synovitis (PVNS), create awareness of this rare condition, and provide guidance for conservative healthcare practitioners for further referral and appropriate management.

We present the case of a 41-year-old recreational runner who presented to the clinic with anterior hip pain of one year duration. Following a clinical history and examination, the patient was diagnosed with clinical femoroacetabular impingement. Radiographs taken at that time displayed mild degenerative joint disease of the left hip joint with coxa profunda. After four weeks of conservative care, the patient reported no improvement in symptoms. The patient was then referred for an MRI, while conservative care continued. Cpd 20m cell line Ten weeks later, the patient's symptoms and functional abilities had worsened. The MRI was obtained and the diagnosis of PVNS was made.

PVNS is a rare disease that can mimic mechanical hip pain. A high index of suspicion should be utilized when symptoms worsen despite conservative care. Referral for advanced imaging is critical for appropriate diagnosis of PVNS.

Vertebral osteomyelitis (OM) is an infectious condition of bone caused by an infecting organism, most commonly Staphylococcus aureus (S. aureus). Though rare in adolescents, it is important to remember that this population has vascularized intervertebral discs prior to skeletal maturity and, therefore, is more susceptible to an osteodiscitis infection.

To determine the possible factors that lead to a delayed diagnosis of osteodiscitis compared to an early diagnosis in an adolescent athlete.

This case provides a unique example of osteodiscitis in an adolescent rowing athlete where an infected heel blister was the only indication toward a diagnosis. Early diagnosis and successful management of osteodiscitis are dependent on recognizing constitutional and non-constitutional signs and symptoms of infection.

In sport, when skin barriers may be compromised more readily, the risk of infection should be considered in the differential diagnosis of unprovoked back pain.

We present a case of an elite cyclist that hesitated to follow the medical advice from her practitioners, as she was determined to train and compete resulting in delayed diagnosis and management of a rare hip pathology.

A 51-year old elite female cyclist had a history of years of hip pain with insidious onset. The chiropractor in this case observed a lack of response to treatment, and advised the patient to get an MRI with suspicion of a labral tear. She eventually agreed to further investigations and was diagnosed with Non-Hodgkin's follicular lymphoma and a labral tear.

Elite athletes are not immune to serious pathology. Chiropractors should be vigilant and ensure to investigate any patients with a lack of response to conservative management. Chiropractors should be aware of the risk of athletic patients that continue to train and compete when advised not to.

This study aims to determine whether manipulative therapy of the hip joint can increase range of motion (ROM) and/or decrease pain in individuals experiencing symptomatic hip pain.

Non-disabled young adults were recruited on campus of a chiropractic college for this randomized crossover study. Subjects' hip active and passive ROM and pain perception were measured. Subjects then received a drop-piece hip manipulation (DPHM) or an alternative treatment, followed by measurement of active and passive ROM and pain.

Eight males and 12 females (n=20) between the ages of 21-32 years completed the study. Statistically significant improvements in numeric pain scale (NRS) and passive abduction were observed for the manipulation group when compared to the alternative treatment. No significant change was observed for all other hip ranges.

DPHM of the symptomatic hip joint in a small sample of young adults resulted in statistically significant improvements in pain and passive abduction when compared to sham manipulation. Due to low sample size, further research is recommended.

To identify sports-focused research priorities to inform the development of a research agenda for sports chiropractors.

A qualitative description study was conducted using semi-structured interviews with 20 sports chiropractic researchers from 8 different countries and focus group interviews with 12 sports chiropractic leaders from Canada.

150 research priorities were identified, and three main themes emerged area of research, research actions, and research methodology. Six areas of research were identified basic science and mechanism research, clinical research, health services research, population health, specific conditions and topics in sport, and chiropractic research in sport. Collaboration in research and contributing to the broader sports research effort were two subthemes identified as research actions, and the remaining codes were related to research methodology.

The research priorities identified can be utilized to plan future research prioritization studies to inform a research agenda for the sports chiropractic field.

To investigate the degree of knowledge North American chiropractors have in regards to concussion diagnosis and management.

A Concussion Knowledge Assessment Tool (CKAT) survey was administered to North American chiropractors through SurveyMonkey.com. This survey was sent to all practicing members of the American Chiropractic Association (ACA) and Canadian Chiropractic Association (CCA).

1321 surveys were completed and analyzed (response rate of 3.3%). The average score of the CKAT amongst North American Chiropractors was 4.82 out of 9. Using our modified scoring method, chiropractors scored 39.44 out of 48.

North American chiropractors who participated in this study demonstrated concussion knowledge and management using the CKAT tool. Further investigation is recommended in order to address learning gaps and updating the CKAT based on current literature and guidelines.

1) To determine which characteristics of adolescent athletes with SRC are associated with 'early' versus 'late' presentation for multimodal treatment; 2) to build a propensity score to investigate the effects of treatment timing during the management of SRCs.

Associations between early (0-7 days) versus late (8-28 days) presentation for treatment and pre-specified sociodemographic, pre-injury and injury characteristics were investigated in a historical cohort study of 2949 multi-sport athletes across Canada aged 12-18 years diagnosed with a SRC in community-based healthcare clinics.

Early presentation was associated with being male, completing a pre-injury baseline assessment, and responding 'yes' or 'no' to having a diagnosed learning disability. Older athletes who reported previous SRCs were less likely to present early. The propensity score demonstrated an area under the curve of 0.71 (95% CI, 0.69 to 0.73).

Male athletes with a completed baseline assessment were more likely to seek early treatment following a SRC, and older athletes who reported a greater number of previous SRCs were less likely to present early. External validation of the propensity score is needed before examining the impact of treatment timing on adolescent athlete recovery outcomes.

To determine the influence of induced fatigue on dynamic balance in healthy athletes.

Systematic review.

PUBMED, MEDLINE, CINAHL, Sports Discus, and the Cochrane library from onset to May 28, 2019.

Eligible studies included any study examining the effects of induced-fatigue on dynamic balance, as measured by the SEBT/YBT, in healthy athletic populations. Studies with a low risk of bias were considered scientifically admissible for a best evidence synthesis.

Fifteen studies with low risk of bias were included - seven investigated recreational athletes while eight focused on competitive athletes. In the recreational population, five of the studies found significant decrease in dynamic balance following the fatiguing intervention. However, the remaining two concluded with insignificant changes. As for the competitive population, three studies showed significant effects of induced fatigue on dynamic balance, while five showed no effects.

There are conflicting results regarding the effects of induced fatigue on dynamic balance.
