Introduction: We report a case of a lost metal platelet from a radiofrequency ablation probe (VAPR VUE Radiofrequency System, Cool Pulse 90, DePuy, Synthes, Switzerland) in the shoulder joint during elective arthroscopic cuff repair. To the best of our knowledge, this kind of an incident during elective arthroscopy has not been described in the literature so far. In addition, we present an algorithm on how to deal with such an incident. Case Report: A 69-year-old woman underwent an arthroscopic subacromial decompression and rotator cuff repair for a torn supraspinatus tendon. While performing the subacromial decompression and after swapping the portals from lateral to posterior, the metal platelet of the electrocautery device got detached from the instrument and lost in the operation field. Several attempts to visualize the lost platelet with the camera failed. Finally, intraoperative fluoroscopic imaging was used to detect the platelet. To confirm the definitive whereabouts of the platelet, two spinal needles were positioned perpendicular to another under x-ray control, both pointing at the missing platelet. After determining the exact location, the platelet could finally be visualized with the camera and removed. Due to this incident, the operation time was extended extensively, and the patient as well as the theatre team was exposed to an unnecessary amount of radiation. Conclusion: This report indicates that an extraordinary incident such as the detachment of a component of the arthroscopic equipment during surgery is possible and should be kept in mind by the surgeon. Therefore, we believe that it is essential to perform a test of integrity at least at the end of every operation. In addition, we are presenting an algorithm on how to deal with the situation of a lost foreign body during arthroscopy, which can be applied to any joint.

Objectives: Despite widespread use of behavioural observations to evaluate child feeding behaviours in research and clinical practice, few studies have comprehensively characterised mealtimes or identified features that differentiate children with and without disordered feeding; these were the aims of the current study. Methods: Mealtime observations were conducted for 18 children with Avoidant Restrictive Food Intake Disorder (ARFID) and 21 typically developing children. Observations were coded inductively, and associations between disorder and observed mealtime actions were examined. Results: Most behaviours were observed across both clinical and non-clinical mealtimes, and many did not differ in frequency between children with and without ARFID. However, significant group differences were observed in the frequencies of behaviours relating to food intake, visual and physical engagement with feeding, and movement during mealtimes. Conclusions: The comparability of behaviours across clinical and non-clinical groups suggests that eating behaviours exist on a continuum from ‘normal’ to ‘abnormal’, with group differences relating to frequency rather than type of behaviour. The behavioural differences observed in this study suggest that identification of children with ARFID should focus on child engagement with food and restlessness during mealtimes. Reliance on emotional and escape-maintained behaviours will lead to under-recognition of families in need of clinical support.
