Eosinophilic Esophagitis and Cow's Milk: Mechanisms, Challenges, and Treatment Perspectives.

Eosinophilic esophagitis is a chronic, antigen-driven, immune-mediated disease characterized by esophageal dysfunction and significant eosinophilic infiltration. Its rising incidence and prevalence over recent decades reflect both increased clinical awareness and the influence of environmental factors such as dietary patterns and allergen exposure. Among food allergens, cow's milk proteins are the most commonly implicated triggers, contributing to esophageal inflammation through complex immunological pathways involving both IgE-mediated and non-IgE-mediated mechanisms.

Favorable Outcome after Liver Transplantation in an Infant with Liver Failure Due to Deoxyguanosine Kinase Deficiency.

: Deoxyguanosine Kinase (DGUOK) deficiency is a very rare disorder characterized by liver dysfunction, neurological manifestations, and metabolic disorders secondary to severely reduced mitochondrial DNA content. These patients develop early-onset liver failure, and their liver transplantation (LT) indication remains debatable due to the possibility of neurological involvement. : We present the case of a 6-month-old female diagnosed with DGUOK deficiency who developed liver failure.

Challenges in Pediatric Liver Retransplantation: A Technical Perspective.

Background/objectives: Liver retransplantation (reLT) is the only option for pediatric patients experiencing graft loss. Despite recent advancements in surgical techniques and perioperative management, it remains a high-risk procedure. Our aim is to describe our experience in pediatric reLT, focusing on the technical aspects and surgical challenges.

Failure to Rescue Pediatric Recipients of Living Donor Liver Transplantation: A Single-Center Study of Technical Complications in 500 Primary Grafts.

Background: The concept of failure to rescue (FTR) has been used to evaluate the quality of care in several surgical specialties but has not been well-studied after living donor liver transplantation (LDLT) in children.

Methods: This study retrospectively reviewed 500 pediatric LDLT performed at a single center between 1993 and 2022. The recipient outcomes were assessed by means of patient and graft survival rates, retransplantation rates, and arterial/portal/biliary complication rates.

Drugs in focus: Botulinum toxin in the therapy of gastrointestinal disorders in children.

What Is Known: Botulinum toxin (BoNT) causes muscle relaxation by inhibiting acetylcholine release from presynaptic motor neurons at the neuromuscular junction.

What Is New: In children with achalasia, BoNT can be considered only in patients in whom rapid weight gain is important to improve surgical outcomes. BoNT has been suggested for treating cricopharyngeal achalasia and delayed gastric emptying.
