AI Article Synopsis

  • Corticosteroid injections (CSIs) are frequently used to treat carpal tunnel syndrome, but recent studies have raised concerns about their association with a higher risk of postoperative infections in orthopedic surgeries.
  • A study conducted from 2010 to 2019 analyzed patients who underwent carpal tunnel release (CTR) and found that those who received preoperative CSIs had a significantly higher rate of postoperative infections compared to those who did not.
  • The research revealed that 41% of patients with infections had received a CSI prior to surgery, suggesting a link between the timing of the injection and the infection risk, although further investigation is needed to explore other contributing factors like dosage and patient comorbidities.

Article Abstract

Purpose: Corticosteroid injections (CSIs) are commonly used in carpal tunnel syndrome; however, recent literature has demonstrated risk of postoperative infection associated with preoperative CSIs in other orthopedic fields. The aim of this study was to assess the relationship of CSIs and postoperative infection following carpal tunnel release (CTR).

Methods: A single-center retrospective review was conducted from 2010 to 2019 to identify patients who underwent CTR with subsequent antibiotic prescription for chart-documented wound infection. A demographically-matched cohort of 100 patients was identified for comparison. Information on patient demographics, comorbidities, injection history, and presence of postoperative infection was collected.

Results: Thirty-nine patients (0.67% of all CTR patients) were identified with postoperative infections, 3 of which (0.05% of all CTR patients) were deep infections. In the infection cohort, 16 of 39 (41%) patients received an injection prior to surgery, whereas 16 of 100 (16%) patients in the control cohort received an injection. History of CSI was significantly more common in patients with postoperative infection, and patients in the infection cohort had a significantly shorter average time from injection to surgery by approximately 55 days.

Conclusions: Corticosteroid injections in the preoperative period are associated with postoperative infection after CTR. Proximity of injection to time of surgery plays a role, although comorbidities, the corticosteroid dose, and frequency of injection require further study to determine risk contribution.

Type Of Study/level Of Evidence: Prognostic III.

Abdominal hernia repair is a common surgical procedure, involving in most cases the use of textile meshes providing a mechanical barrier to consolidate the damaged surrounding tissues and prevent the resurgence of the hernia. However, in more than half cases postoperative complications such as adhesions and infections occur at the surface of the mesh, leading to chronic pain for the patient and requiring the removal of the implant. One of the most promising strategies to reduce the risk of postoperative adhesions and infections is to add a physical barrier between the mesh and the abdominal walls.

Objective: To quantify the otolaryngologic diagnoses encountered in outpatient clinics by otolaryngology-head and neck surgery (OHNS) residents during their 5 years of postgraduate training.

Methods: This is a retrospective review at a single institution following 5 consecutive graduating resident cohorts throughout their training. The electronic health record was queried for OHNS clinic encounters from 2013 through 2022 during which the resident physicians were included as the visit provider or assistant to an attending physician.

BACKGROUND Perineal injuries affecting the scrotum and penis are rare in pediatric patients, owing to the protective anatomy of the male genitalia. However, when such injuries do occur, timely surgical intervention is crucial. This kind of damage might not be life-threatening but could cause functional disorders and have a huge impact on the patients' psychological condition if not treated appropriately, especially as they enter puberty.

Introduction: This study compared the clinical outcomes of allogenic cultured limbal epithelial transplantation (ACLET) and cultivated oral mucosal epithelial transplantation (COMET) in the management of limbal stem cell deficiency (LSCD).

Methods: Forty-one COMET procedures in 40 eyes and 69 ACLET procedures in 54 eyes were performed in the Corneoplastic Unit of Queen Victoria Hospital, East Grinstead. Data were examined for demographics, indications, ocular surface stability, absence of epithelial defect, ocular surface inflammation, visual outcomes, and intra- and postoperative complications.
