Hypercalcemia is a significant complication in cancer patients, primarily caused by parathyroid hormone-related peptide (PTHrP) and, rarely, by parathyroid hormone (PTH) production from tumors. We report a case of severe hypercalcemia in a woman with uterine cancer who exhibited elevated PTH and PTHrP levels. Surgical intervention revealed dedifferentiated endometrial carcinoma.

Article Synopsis
- A 78-year-old man displayed symptoms including fever, arthralgia, and skin lesions, and was diagnosed with relapsing polychondritis and myelodysplastic syndromes after appropriate tests.
- Despite initial treatment with high-dose prednisolone leading to remission, he experienced a relapse and developed an arteriovenous fistula related to an iliac artery aneurysm.
- Further genetic testing confirmed a diagnosis of VEXAS syndrome, suggesting that arteriovenous fistulas can occur as complications, highlighting the need for timely surgical intervention and awareness among physicians.
Intercalation of naphthoic acid into Zn/Al layered double hydroxide.
J Nanosci Nanotechnol
January 2009
Zn/Al Layered Double Hydroxide (Zn/Al LDH) consists of positively charged metal hydroxide sheets with anions located between the layers to compensate charges. By the reaction of carbonate Zn/Al LDH (CO3(2-)) with 2-naphthoic acid, two intercalation compounds were obtained indicating the occurrence of ion exchange reaction. Interlayer spacing increased from 0.
