Impact of storage conditions on the fracture reliability and physical properties of a dental resin-based composite.

This study investigated the impact of 'storage condition' and 'period of storage' on selected physico-mechanical properties and fracture reliability of a resin-based composite (RBC). Specimens, prepared from a nanofilled RBC (Filtek Z350 XT; 3M ESPE), underwent tests for degree of conversion (DC), flexural strength (σ), flexural modulus (E), and hardness. The specimens were initially grouped into dry storage at 37°C or wet storage in distilled water at 37°C.

Spontaneous retroperitoneal biloma in a patient with choledocholithiasis: Presentation of case.

Introduction And Importance: Spontaneous perforation of the biliary tree, resulting in retroperitoneal biloma in adults is an extremely rare condition, and may unfold to a potentially fatal outcome, particularly when the diagnosis and definitive treatment are delayed.

Case Presentation: We report a case of a 69-year-old male who presented to the emergency room with abdominal pain, localized to the right quadrants, associated with jaundice and dark-coloured urine. Abdominal imaging including CT scan, ultrasound and magnetic resonance cholangiopancreatography (MRCP) revealed a retroperitoneal fluid collection, a distended gallbladder with wall thickening and lithiasis, as well as a dilated common bile duct (CBD) with choledocholithiasis.

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.
