From predictive algorithms to generative intelligence: a decadal bibliometric mapping of global research frontiers in AI-driven mental health (2016-2025).

Foreign body ingestion in pediatrics is one of the most frequent emergencies []. The most commonly found foreign bodies worldwide are coins, followed by magnets, button batteries, pins, and organic foreign bodies [,]. To date, the first reported case of toothbrush ingestion was in 1882, and of all the cases reported in subsequent years, none involved spontaneous expulsion []. Patients with mental illnesses or eating disorders are the most prone to the accidental ingestion of unusual objects. In these patients, ingestion may be inadvertent and therefore untreated, increasing the risk of complications [, , , ]. Diagnosis can be made through medical history and radiological tests, which allow detection of the location, size, shape, and quantity of foreign bodies. Although sometimes they may not be visible as they appear as radiolucent images []. While endoscopy is a safe and effective technique for foreign body removal, in some cases it is not the first option []. We report the first case in our health unit of a 13-year-old male patient who ingested a toothbrush, which was successfully removed via upper gastrointestinal endoscopy. A 13-year-old patient was admitted to the emergency department with mild abdominal pain and nausea, without vomiting, after ingesting a toothbrush 3 hours prior to admission. On physical examination, his heart rate was 97 beats/minute, temperature 35.2°C, blood pressure 100/58 mmHg, and oxygen saturation 98%. His abdomen was distended, nontender, without any palpable masses, and slightly tender to palpation in the left hypochondrium. During re-interviewing, the patient was uncommunicative and easily choked. He reported having an eating disorder for the past 4 months, as he had previously induced vomiting with his toothbrush. An abdominal X-ray was performed in the upright and lateral views (), revealing a radiopaque image below the left costal margin, apparently located in the stomach, consistent with the bristles of the toothbrush. Since a specialist was unavailable that evening and the patient presented no abdominal alarm symptoms, the patient was admitted and kept NPO (nothing by mouth) until evaluation by gastroenterology the following morning.
