Objective: To investigate the incidence of acute injuries and soccer-related chronic pain from long-term training and during matches in adolescent players using natural grass turfs (NT) and artificial turfs (AT).
Design: Case-controlled prospective study.
Setting: Institutional-level Fédération Internationale de Football Association Medical Centre of Excellence.
Participants: Youth soccer players (12-17 years of age) from 6 teams, with a predominant tendency to train on either NT or AT, were included. Of 332 players enrolled in this study, 301 remained to completion.
Interventions: Medically diagnosed acute injuries and chronic pain were recorded daily by team health care staff throughout 2005, and reports were provided monthly to the authors.
Assessment Of Risk Factors: Noninvasive prospective study.
Independent Variables: Age and turf type.
Main Outcome Measures: Acute injuries per 1000 player hours on each surface and chronic complaints per 1000 player hours were evaluated according to frequency of surface used > or = 80% of the time. Incidence rate ratio (IRR) of acute injuries and chronic complaints during play on NT and AT was calculated.
Results: There was no significant difference in the incidence of acute injuries between the 2 surfaces during training and competition. However, the AT group showed a significantly higher incidence of low back pain during training (IRR, 1.62; 95% confidence interval, 1.06-2.48). Early adolescence and prolonged training hours were factors associated with an increased incidence of chronic pain in the AT group.
Conclusion: Adolescent players routinely training on AT for prolonged periods should be carefully monitored, even on AT conforming to new standards.

Objectives: A recent coronavirus-related factory shutdown led to a global shortage of iodinated contrast. The authors evaluated how the contrast shortage impacted percutaneous coronary interventions (PCI).
Methods: Using a statewide database incorporating CathPCI registry data from 19 hospitals, the authors evaluated 2 time periods: pre-shortage (May 1, 2021 - April 30, 2022) and during the shortage (May 1, 2022 - October 31, 2022).
Fracture-related infection (FRI) is a serious complication that occurs primarily in surgically treated fractures. FRIs occur when bacteria enter the site of bony injury and alter the healing inflammatory response within the bone. This can prevent bone regeneration and can lead to long-lasting complications such as chronic infection, pain, nonunion, and amputation.

Lateral epicondylitis is a common condition that can be very frustrating to patients. Many patients will improve without any acute interventions.

These injuries often result in acute weakness and have widely differing treatment options depending on the severity and the location of the injury within the upper extremity. Zone I injuries can often be treated nonoperatively with the potential for pinning of any large bony avulsion fragments.
