Background: Evaluation of lesions of the biliary tract are essential to diagnose given the dismal outcomes of cholangiocarcinoma. Historically, these diagnoses were made using brush biopsies obtained under Endoscopic Retrograde Cholangiopancreatography (ERCP). To increase the accuracy of biliary biopsies, SpyGlassTM Discover cholangioscopy guided biopsy has been developed, providing greater tissue yield and direct visualization of the biliary epithelium.

Parkinson's Disease (PD) is the second most prevalent neurodegenerative disease worldwide due to loss of dopaminergic neurons projecting from the basal ganglia (BG). It is associated with various motor symptoms that are grouped into subtypes, each with different clinical presentations and disease progressions. Neuroimaging biomarkers focusing on regions a part of motor circuits projecting from the BG can distinguish and improve overall subtyping.

Article Synopsis
  • Acquired benign tracheoesophageal and bronchoesophageal fistulas (TEFs) are often linked to granulomatous infections, primarily caused by medical interventions, with rare organisms like Candida albicans and Actinomyces involved.
  • A case study describes a patient experiencing symptoms like cough and weight loss, leading to the discovery of a fistula and complications such as actinomycetoma and broncholithiasis due to the dual infection.
  • The report emphasizes the importance of recognizing this uncommon co-infection and provides a diagnostic algorithm to aid healthcare professionals in identifying and treating TEs effectively.

Article Synopsis
  • Ciliated hepatic foregut cyst (CHFC) is a rare and generally benign liver cyst that comes from embryonic foregut epithelium and is often asymptomatic, though some may have vague abdominal symptoms.
  • Although imaging techniques are not enough for a correct diagnosis—since they can resemble other serious conditions like intrahepatic cholangiocarcinoma—histologic confirmation is necessary for a definitive diagnosis to rule out the potential for malignant transformation, especially in larger cysts.
  • The article discusses a specific case of CHFC and includes a literature review, along with a proposed algorithm for accurately diagnosing these cysts.
