Consistency between headache diagnoses and ICHD-3 criteria across different levels of care.

Background: Diagnosing headache disorders poses significant challenges, particularly in primary and secondary levels of care (PSLC), potentially leading to misdiagnosis and underdiagnosis. This study evaluates diagnostic agreement for migraine, tension-type headache (TTH), and cluster headache (CH) between PSLC and tertiary care (TLC) and assesses adherence to the International Classification of Headache Disorders 3rd edition (ICHD-3) guidelines.

Methods: A retrospective, cross-sectional analysis was conducted at Charité - Universitätsmedizin Berlin's tertiary headache center.

Total Serum Immunoglobulin E in a Cohort of Children with Food Allergy.

Background: Total serum immunoglobulin E (TsIgE) has not been examined in children with food allergy.

Objective: Evaluate associations of TsIgE with patient, household, environmental and community-level characteristics among children with food allergy.

Method: Linear mixed effect models of data from 398 Black and/or African American (B/AA) and White and/or European American (W/EA) children with allergist-diagnosed food allergy from the multi-center, observational cohort FORWARD; TsIgE in kU/L was the primary outcome measure.

The Impact of Unilateral Transfemoral Amputation on Lumbar Bone and Muscle Quality.

Objective: To examine the long-term perioperative changes in lumbar bone density, muscle size and fatty atrophy, and facet degeneration after transfemoral amputation (TFA).

Design: All patients who underwent TFA at an academic center between 2002-2022 were retrospectively identified. Patients were required to have preoperative and postoperative CT (>1 year) and regularly utilize a prosthesis.
