While the gross mechanical abnormalities contributing to posttraumatic osteoarthritis (PTOA) have been well described, new research is demonstrating that these insults to the articular cartilage may also initiate changes in the joint microenvironment that seed the development of PTOA.

A growing amount of literature has identified key biomarkers that exhibit altered expression in the synovial fluid following a knee injury, with a portion of these molecules remaining elevated in the years following an injury.

These biomarkers have the potential to aid in the early detection of PTOA before radiographic evidence becomes apparent. Furthermore, deciphering the processes that occur within the articular microenvironment after trauma may allow for better identification of therapeutic targets for the prevention and earlier treatment of PTOA.

Carpal tunnel steroid injection is a nonoperative intervention for the treatment for idiopathic carpal tunnel syndrome (CTS). The antifibrotic, anti-inflammatory, and antiedematous properties of steroids account for their therapeutic effects in the context of CTS; however, their relative contribution has not been clarified.

Fibroblasts from subsynovial connective tissues (SSCT) were intraoperatively collected from patients with idiopathic CTS and were incubated with or without the steroid triamcinolone acetonide (TA) for 1, 3, and 7 days; the expression of fibrosis-related genes and inflammatory cytokines was evaluated using quantitative reverse transcription-polymerase chain reaction. A clinical prospective study was conducted with patients who received carpal tunnel TA injections. We performed clinical and electrophysiological evaluations before and 1, 3, and 5 months after TA injection; and we compared the median nerve, flexor tendon, and SSCT areas and the median nerve flattening ratio before and 1 month after TA injection using 3-T magnetic resonance imaging (MRI).

TA induced downregulation of the fibrosis-related genes Col1A1 (collagen type I alpha 1 chain), Col1A2, and Col3A1 but not the inflammation-related genes. The nerve flattening ratio did not change after TA injection according to the MRI-based observation of the median nerve, flexor tendon, and SSCT areas.

The therapeutic effects of injected TA are apparently mediated by its antifibrotic rather than its anti-inflammatory and antiedematous properties. TA probably alters the properties but not the morphology of SSCT.

To evaluate whether ultrasound can differentiate between cellulitis and angioedema from insect bites in pediatric patients.

A prospective, pre-post study in an urban pediatric emergency department of patients younger than 21 years with soft tissue swelling from insect bites without abscesses were enrolled. Treating physician's pretest opinions regarding the diagnosis and need for antibiotics were determined. Ultrasound of the affected areas was performed, and effects on management were recorded. Further imaging, medications, and disposition were at the discretion of the enrolling physician. Phone call follow-ups were made within a week of presentation.

Among 103 patients enrolled with soft tissue swelling secondary to insect bites, ultrasound changed the management in 27 (26%) patients (95% confidence interval [CI], 18-35%). Of the patients who were indeterminate or believed to require antibiotics, ultrasound changed management in 6 (23%) of 26 patients (95% CI, 6%-40%). In those patients who were belie.
Adverse events (AEs) in health care are a public health issue. Although mandatory, error disclosure is experienced by health providers as a difficult task.

In this prospective study, the primary objective was to assess performance in disclosing AEs to simulated parents using a validated scale before and after training among a pediatric residents' population. Secondary objectives were to assess correlation with year of residency, sex, and previous experience and to analyze gain in knowledge (theoretical pretest/posttest scores) and satisfaction. Two evaluation simulations (simulation [SIM] 1 and SIM 2) were scheduled at 3-week interval. In the intervention group, mastery learning was offered after SIM 1 including a didactic approach and a training session using role-playing games. For the control group, the course was carried out after SIM 2. Assessments were performed by 2 independent observers and simulated parents.

Forty-nine pediatric residents performed 2 scenarios of AE disclosure in front of simulresidents. IDE397 It is important to train residents for these situations to avoid traumatic disclosure generating a loss of confidence of the family regarding physicians and possible lawsuits.
Stridor is a common presenting symptom for children in emergency departments (EDs) and usually represents an infectious process, such as croup, or aspiration of a foreign body. We present the case of an otherwise healthy 5-year-old girl with episodic increased work of breathing for several months that was initially diagnosed as asthma by her primary care physician. She subsequently presented to the ED with acutely worsening noisy breathing and dyspnea. Patient and parent denied any recent foreign body ingestions or choking episodes. We gave multiple doses of racemic epinephrine in the ED without symptom improvement. A lateral neck x-ray showed an occlusive subglottic airway mass. Otolaryngology (ENT) evaluation demonstrated an 85% airway occlusion. The mass was partially resected, resolving all of her respiratory symptoms. Although primary airway tumors in children are rare, they must be considered on the differential diagnosis of new noisy breathing or respiratory distress. Failure to diagnose these tumors distress. Failure to diagnose these tumors in a timely manner can be life-threatening.
While hardware removal may improve patient function, the procedure carries risks of unexpected outcomes. Despite being among the most commonly performed orthopaedic procedures, scant attention has been given to its complication profile.

We queried the American Board of Orthopaedic Surgery (ABOS) de-identified database of Part II surgical case lists from 2013 through 2019 for American Medical Association Current Procedural Terminology (CPT) implant-removal codes (20680, 20670, 22850, 22852, 22855, 26320). Hardware removal procedures that were performed without any other concurrent procedure ("HR-only procedures") were examined for associated complications.

In the 7 years analyzed, 13,089 HR-only procedures were performed, representing 2.1% (95% confidence interval [CI], 2.1% to 2.2%) of the total of 609,150 surgical procedures during that period. A complication was reported to have occurred in association with 1,256 procedures (9.6% [95% CI, 9.1% to 10.1%]), with surgical complications reported in associand nerve damage were reported to have relatively low rates of occurrence, and associated life-threatening complications occurred rarely, surgeons and patients should be aware that hardware removal carries a definite risk.

This report presents a logical and effective technique for removing a bullet from the sacroiliac joint (SIJ). The surgery involved a fluoroscopy-guided anterior extraperiosteal lateral window approach. Other than a transient femoral nerve neuropraxia, there were no complications. A literature review identified 3 reports on bullet removal from the SIJ of adult patients.

An anterior extraperiosteal approach for removing bullets from the SIJ in pediatric patients provides satisfactory results. When deciding whether to remove a bullet from the SIJ, the location, joint diastasis, and patient's age should be considered.

A full-term neonate presented with right lower extremity ischemia at birth because of spontaneous thrombosis of the right common iliac artery. He was initially managed with supportive treatment, anticoagulation, and dressings; however, advanced gangrenous changes precluded salvage of the ischemic limb. A guillotine amputation was performed at day 15 of life, and the stump went on to heal well by secondary intention.

Thromboembolic events occurring in infancy are well-recognized phenomena; however, it is far rarer to encounter a neonate born with "congenital gangrene". We discuss the etiology, approach to diagnosis, and treatment of this rare but devastating condition.

Flap-based limb salvage surgery balances the morbidity and complexity of soft tissue transfer against the potential benefit of preserving a functional limb when faced with a traumatized extremity with composite tissue injury. These composite tissue injuries are well suited for multidisciplinary management between orthopaedic and plastic surgeons. Thus, it makes intuitive sense that a collaborative, orthoplastic approach to flap-based limb salvage surgery can result in improved outcomes with decreased risk of flap failure and other complications, raising the question of whether this orthoplastic team approach should be the new standard of care in limb salvage surgery.

(1) Is there an association between increased annual institutional volume and perioperative complications to include free and local flap failure (substantial flap viability loss necessitating return to the operating room for debridement of a major portion or all of the flap or amputation)? (2) Is an integrated orthoplastic collaborative appromplex extremity trauma in the civilian setting, suggest a benefit to free tissue coverage to treat complex extremity trauma with adequate practice volume and collaboration. We demonstrated that flap failure and flap-related complications are inversely associated with institutional experience regardless of flap type. Additionally, a collaborative orthoplastic approach was associated with decreased flap failures. However, these results must be interpreted with consideration for potential confounding between the increased case volume coinciding with more frequent collaboration between orthopaedic and plastic surgeons. Given these findings, consideration of an orthoplastic approach at high-volume institutions to address soft tissue coverage in complex extremity trauma may lead to decreased flap failure rates.
