Objective: To examine the concordance of pediatric radiograph interpretation between emergency medicine residents (EMRs) and radiologists.
Methods: A prospective, observational study was performed in a university pediatric ED with an annual census of 60,000 visits. Radiographs ordered by EMRs from December 1993 through October 1994 were initially interpreted solely by the EMR, with subsequent unmasked final review by attending radiology staff. Misinterpreted radiographs were placed into 3 categories. The groupings included overreads, underreads with no change in treatment, and underreads that required a change in treatment.
Results: A total of 415 radiographs were interpreted by PGY1-3 residents. Overall concordance was found for 371 radiographs (89.4%). There were 44 misinterpretations (10.6%), with 24 (5.78%) overreads, 13 (3.13%) underreads, and 7 (1.69%) underreads that required follow-up interventions. Misinterpretations were similar for the different levels of training: [table: see text] The 5 most frequently ordered radiographs were chest (28%), ankle (7%), foot (6%), wrist (5%), and hand (5%). The most frequently misinterpreted radiographs were sinus, foot, shoulder, facial, and hand.
Conclusion: 89.4% of all the radiographs interpreted by PGY1-3 residents were read correctly. Only 1.69% of the misinterpreted radiographs led to a change in management. Level of training did not significantly correlate with radiograph misinterpretation rates.

Iodoform, a halogenated organic compound, has been a cornerstone in surgical practice due to its potent antiseptic and antimicrobial properties. This comprehensive review examines the historical evolution, mechanism of action, clinical applications, and safety profile of iodoform across various surgical disciplines. Historically significant formulations like Whitehead's varnish and bismuth iodoform paraffin paste (BIPP) demonstrated remarkable efficacy in wound healing during the late 19th and early 20th centuries.

Objectives: This study evaluated the number and quality of working length (WL) and master cone (MC) radiographs taken during root canal treatment by dental undergraduates, and their associations with the technical quality of root canal fillings (TQRCF) and endodontic outcomes (EO).
Methods: A retrospective evaluation of radiographs from 303 root canal-treated teeth in 231 patients was conducted, with 72 patients attending recall visits to assess EO. The chi-square and one-way analysis of variance tests were performed.
Pedicle ossification following mandibular reconstruction using fibular free flap in a patient with osteoradionecrosis of the jaw: a case report.

Article Synopsis
- Pedicle ossification is a rare complication that can occur after using a fibular free flap (FFF) for mandibular reconstruction, potentially simulating tumor recurrence and leading to diagnostic challenges.
- A case study of a 38-year-old male with squamous cell carcinoma highlighted how postoperative complications led to the need for FFF reconstruction, and over 4 years, CT scans showed ossification in the flap's vascular pedicle, yet the patient remained asymptomatic.
- Regular imaging and clinical assessments are key to distinguishing ossification from tumor recurrence, with surgery usually only considered if symptoms arise.
Cancers not detected in one-view breast tomosynthesis screening-characteristics and reasons for non-detection.

Radiology Diagnostics, Department of Translational Medicine, Lund University, Skåne University Hospital, Malmö, Sweden.
Objectives: Limited understanding exists regarding non-detected cancers in digital breast tomosynthesis (DBT) screening. This study aims to classify non-detected cancers into true or false negatives, compare them with true positives, and analyze reasons for non-detection.
Materials And Methods: Conducted between 2010 and 2015, the prospective single-center Malmö Breast Tomosynthesis Screening Trial (MBTST) compared one-view DBT and two-view digital mammography (DM).
Paediatric Hand Fractures - A Review.

Paediatric hand fractures account for approximately 25% of hand-related emergency department visits, making them the second most common childhood fractures after distal forearm fractures. These injuries are more prevalent in boys and peak ages between 9 and 14 years. Hand fractures in children are primarily caused by crushing injuries and, increasingly in older children, by sports-related activities.
