Esophageal Mucosal Impedance Assessment for the Diagnosis of Gastroesophageal Reflux Disease.

Background/aims: Diagnosing gastroesophageal reflux disease (GERD) is sometimes challenging because the performance of available tests is not entirely satisfactory. This study aims to directly measure the esophageal mucosal impedance during upper gastrointestinal endoscopy for the diagnosis of GERD.

Methods: Sixty participants with typical symptoms of GERD underwent high-resolution esophageal manometry, 24-hour multichannel intraluminal impedance-pH monitoring, upper gastrointestinal endoscopy, and mucosal impedance measurement.

Lupus mastitis: A rare breast cancer differential diagnosis.

Lupus mastitis is an uncommon SLE breast manifestation. Clinically, it can present itself as a malignant-like mass. Therefore, a tissue biopsy is warranted to confirm the diagnosis.

Henrique Dumont: how a traumatic brain injury contributed to the development of the airplane.

The life and death of Henrique Dumont (1832-1892) is little known, being usually remembered as Alberto Santos-Dumont's father. This report describes the history of this Brazilian engineer, also known as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic.

Atypical Presentation of PHACE Syndrome: Hidden Facial Hemangioma.

PHACE(S) syndrome is a neurocutaneous syndrome with a wide array of presentations. The most known and present trait is facial hemangioma > 5 cm. The name is an acronym for Posterior fossa malformations, infantile Hemangiomas, Arterial anomalies, aortic Coarctation, Eye abnormalities, and middle-line malformations of the Sternum.
