RESUMO
Adhesive capsulitis following vaccination is a rare complication secondary to improper intramuscular (IM) deltoid vaccine administration. It is considered a subset of the broad category known as shoulder injury related to vaccine administration (SIRVA). SIRVA typically results from improper shoulder anatomic localization prior to injection, leading to erroneous placement of the needle into the glenohumeral joint capsule or subacromial space. This can trigger a wide array of pathologies, including adhesive capsulitis. We present the first known case of adhesive capsulitis following improper tetanus-diphtheria (Td) vaccine administration. The patient, a previously healthy middle-aged female, began experiencing significant anterior left shoulder pain the day following a Td booster vaccination. She remarked receiving the injection "higher up" in the shoulder than normal. Over the next two weeks, she began noting significant shoulder stiffness, which was followed by a progressive loss of shoulder range of motion. Her symptoms persisted for four months without definitive diagnosis or treatment. After four months of symptoms, the patient visited an outpatient sports medicine clinic where the diagnosis of adhesive capsulitis was made. Although the patient was referred for physical therapy, focusing on gentle range of motion (ROM) and stretches, followed by a planned isometric strengthening program once ROM improved, she was eventually lost to follow-up, and her recovery is unclear. Given the rarity of the diagnosis, it is unclear if adhesive capsulitis, secondary to improper IM vaccination, follows the same temporal course as "classic" adhesive capsulitis or results in a different timeframe of recovery. Further studies are needed on this subject.
RESUMO
Stress fractures are a common and significant source of pain and burden that can require long periods of rest from physical activity to allow adequate healing. Specifically in athletes or those with physically demanding occupations, the prolonged period of rest and the potential for requiring surgical intervention in the case of poor or delayed healing can have devastating impacts on these individuals' careers and socioeconomic well-being. In this population, successful healing, in addition to a quicker healing time and a sooner return to activity, are important outcomes when faced with treating stress fractures. The use of low-intensity pulsed ultrasound (LIPUS) to accelerate bone healing has been a topic of investigation, though little research has explored the use of LIPUS specifically in the physically active population. The purpose of this study was to review the existing literature on the use of LIPUS for stress fracture healing in the physically active population with the outcome of a quicker return to sport or physical duties. The PubMed and Embase databases were screened for relevant articles using defined Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Two independent researchers screened articles using PICOS criteria for inclusion in the review. Data were independently extracted regarding study and population characteristics as well as outcome measures, including time to healing of fractures and time to return to sport or physical activity. Five studies were ultimately included in the systematic review. One study investigated the use of LIPUS in pediatric athletes with spondylolysis, while four studies investigated lower extremity stress fractures in adult populations. All reported the outcomes of either rate or time to healing and ability to return to sport or activity. One study found a statistically significant improvement in the rate of bone union in the intervention group undergoing LIPUS compared to the control. Two studies found a statistically significant decrease in the time to resolution of symptoms, allowing an earlier return to sport or physical duties. Two studies found no difference in the time to healing or success rate of healing between the LIPUS group and the control group. This review of the literature suggests that the use of LIPUS for the treatment of stress fractures in the athletic or physically active population has the potential to expedite the resolution of symptoms and return to activity. Due to the heterogeneity of the existing studies, more research is needed to definitively determine the most appropriate clinical application of LIPUS and its most effective ultrasound settings. Further research should be directed toward more controlled studies specifically investigating the athletic and physically active population.

The following fictional case is intended as a learning tool within the Pathology Competencies for Medical Education (PCME), a set of national standards for teaching pathology. These are divided into three basic competencies: Disease Mechanisms and Processes, Organ System Pathology, and Diagnostic Medicine and Therapeutic Pathology.
