Analysis of maternal mortality in Berlin, Germany - discrepancy between reported maternal mortality and comprehensive death certificate exploration.

Objectives: The Organisation for Economic Cooperation and Development (OECD) estimates an average maternal mortality rate (MMR) of around 3.4 maternal deaths per 100,000 live births for 2019-2021, based on relevant diagnoses on death certificates. However, Germany does not currently have a registry for recording the number of maternal deaths.

Organ-specific symptom patterns during oral food challenge in children with peanut and tree nut allergy.

Background: Peanut and tree nut allergies are common in childhood and often severe in nature. The clinical picture shows a wide variety of symptoms.

Objective: To analyze the distribution of clinical symptoms and severity during oral food challenges (OFC) in children.

Different Patterns of Foods Triggering FPIES in Germany.

Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food allergy mainly affecting infants and young children. Allergic FPIES reactions differ from IgE-mediated food allergies, for example, regarding elicitors and clinical course.

Objective: The aim of our study was to describe causative agents and development of tolerance in German children with FPIES.

Scout-guided needle placement-a technical approach for dose reduction in CT-guided periradicular infiltration.

Purpose: To develop and evaluate a technical approach for CT-guided periradicular infiltration using quantitative needle access and guidance parameters extracted from CT scout images.

Methods: Five 3D-printed phantoms of the abdomen mimicking different patients were used to develop a technical approach for scout-guided periradicular infiltration. The needle access point, puncture depth, and needle angulation were calculated using measurements extracted from anterior-posterior and lateral CT scout images.

Characterization of office laser printers for 3-D printing of soft tissue CT phantoms.

The purpose of our study is to develop and evaluate a method for radiopaque 3-D printing (R3P) of soft tissue computed tomography (CT) phantoms with office laser printers. Five laser printers from different vendors are tested for toner CT attenuation. A liver phantom is created by printing CT images of a patient liver on office paper.
