Silicone allergy manifestation in pediatric ventriculoperitoneal shunting: navigating diagnostic challenges and customizing therapeutic approaches. Illustrative case.

Background: A silicone allergy can significantly impact the efficacy of ventriculoperitoneal shunt devices used in hydrocephalus treatment. Its clinical presentation often resembles infectious ventriculitis, characterized by altered cerebrospinal fluid (CSF) parameters, including low glucose levels, elevated protein concentrations, and increased white blood cell counts predominantly comprising eosinophils.

Observations: The authors report the case of an 18-month-old male who experienced recurrent shunt malfunction linked to CSF changes indicative of infectious ventriculitis.

[Concomitant presence of a gastric adenocarcinoma and gastrointestinal stromal tumor: report of one case].

The concomitant presence of a primary gastric adenocarcinoma and a gastrointestinal stromal tumor in the stomach is uncommon. We report a 68-year-old male with an advanced gastric adenocarcinoma. During gastrectomy, a nodular intramural lesion was found.
