Cranial ultrasound performance assessment tool: development and validation.

AIM: A standard assessment tool for direct evaluation of procedural skills to ensure proficiency of trainees is necessary for cranial ultrasound (US) in clinical practice. This study created and validated an assessment tool for cranial US performance by radiologists. MATERIAL AND METHODS: An initial evaluation tool for cranial US using criteria was developed based on existing literature. The assessment form was modified using a three-round Delphi process by an expert panel, conducted between January 2021 and April 2021. Rubric scales for grading were added once consensus regarding generated items was reached. Experts confirmed the final assessment tool using a rubric scale. Two raters evaluated cranial US performance of 27 residents in video clips using the tool. Reliability and percent agreement were assessed. RESULTS: Seventeen pediatric radiologists working in different settings participated in the expert panel. The content validation of the proposed evaluation tool was enabled by expert pediatric radiologists. Following three rounds of the Delphi process, the initial 14-item assessment form became a final 15-item form. A three-part rubric scale was used in the final form (preparation, US machine operation, and cranial US performance). Interrater reliability was evaluated with Cohen's Kappa. The Kappa value and percent interrater agreement for most items was moderate to almost perfect (0.42-0.93 and 77.8-100%, respectively). The Cronbach's alpha values for both raters were 0.856 and 0.891. CONCLUSIONS: This study produced the first validated cranial US assessment tool using a modified Delphi method. The final assessment form is a simple and reliable tool.

Pancreaticopleural fistula in a Thai boy with SPINK1 c.101A>G substitution variant-related chronic pancreatitis: a case report and literature review.

Background: Chronic pancreatitis is the most common etiology of pancreaticopleural fistula (PPF) in children, and underlying genetic variations are now widely known, accounting for most chronic pediatric pancreatitis. Case report: We describe a case of previously undetected chronic pancreatitis and PPF with a SPINK1 variation in a 10-year-old Thai boy who presented with massive left pleural effusion. Magnetic resonance cholangiopancreatography (MRCP) revealed disruption of the pancreatic duct, which was communicating with a large pancreatic pseudocyst with mediastinal extension. The patient subsequently underwent endoscopic intervention with improved clinical symptoms. We also reviewed the imaging findings of 12 other reported cases of pediatric PPF. Conclusions: Massive pleural effusion due to PPF can be an atypical manifestation in children with chronic pancreatitis. MRCP is the preferable imaging study for PPF due to the production of highly detailed images of pancreatic duct disruptions and anatomy, and the imaging is helpful to guide for appropriate treatment. Tests for genetic variation are also recommended in a child with chronic pancreatitis.
