Successful Outcome in an Adolescent with Artery of Percheron Occlusion who was Treated with Tissue Plasminogen Activator.

Background: Ischemic stroke is relatively rare in children, leading to a low level of suspicion and delayed diagnosis, particularly in cases of posterior circulation occlusion when symptoms are less indicative. Occlusion of the artery of Percheron (AOP) results in nonspecific neurologic symptoms, including drowsiness, aphasia or dysarthria, ophthalmoplegia, ataxia, and dysmetria. Previous reports, mainly in adults, described late diagnosis and severe residual disability.

Retained metal fragments following esophageal button battery impaction.

Button battery (BB) impaction in the esophagus requires immediate endoscopic removal and meticulous follow-up, including serial cross-sectional imaging, preferably with magnetic resonance imaging (MRI). However, BBs quickly degrade in the esophagus, and metallic fragments may remain in the injured mucosa following removal. This metallic debris can cause thermal injury during MRI, potentially aggravating local injury.

Automatic linear measurements of the fetal brain on MRI with deep neural networks.

Purpose: Timely, accurate and reliable assessment of fetal brain development is essential to reduce short and long-term risks to fetus and mother. Fetal MRI is increasingly used for fetal brain assessment. Three key biometric linear measurements important for fetal brain evaluation are cerebral biparietal diameter (CBD), bone biparietal diameter (BBD), and trans-cerebellum diameter (TCD), obtained manually by expert radiologists on reference slices, which is time consuming and prone to human error.

[Long-term results of excision of anal fissure in combination with lateral subcutaneous sphincterotomy].

One hundred and seventeen patients with anal fissure underwent fissure excision in combination with lateral subcutaneous sphincterotomy. The mean follow-up after treatment was 4.3 years.
