[Maternal lupus diagnosed through skin lesions of a newborn].

Directly after birth a newborn was found to have distinctive skin lesions on her face. The lesions were suspicious for neonatal lupus. Her asymptomatic mother tested positive for anti-SSA/Ro and anti-SSB/La antibodies.

"It's not lupus". A placental site trophoblastic tumor presenting as a lupus-like paraneoplastic syndrome. A grand round case.

Placental site trophoblastic tumor (PSTT) is a rare subtype of gestational trophoblastic disease. Association of PSTT and nephrotic syndrome is exceedingly rare and has been described in 8 cases thus far. In all cases hysterectomy was performed within months after onset of symptoms, leading to immediate remission of nephrotic syndrome, except for one patient who died of complications of PSTT.

Post-hepatectomy liver regeneration in the context of bile acid homeostasis and the gut-liver signaling axis.

Background: Liver regeneration following partial hepatectomy (PHx) is a complicated process involving multiple organs and several types of signaling networks. The bile acid-activated metabolic pathways occupy an auxiliary yet important chapter in the entire biochemical story. PHx is characterized by rapid but transient bile acid overload in the liver, which constitutes the first wave of proliferative signaling in the remnant hepatocytes.
