Malignancies in patients with psoriasis during and after biological therapy: A single-center experience.

Over a 14-year period from 2010 to 2023, we treated 86 psoriasis patients with various biological agents at Asahikawa City Hospital, and 12 malignancies occurred in 11 of the patients. The numbers of malignancies by organ were as follows: four urogenital, three hematological, two gastrointestinal, one breast, one thyroid, and one lung. In two patients without cancer-related symptoms, elevated serum Krebs von den Lungen-6 levels led to the detection of intrahepatic cholangiocarcinoma or thyroid cancer, and they did not have interstitial lung disease.

Impairment of ciprofloxacin absorption by calcium polycarbophil.

The effect of calcium polycarbophil on the absorption of ciprofloxacin, a broad-spectrum antibacterial agent, was evaluated in an in vitro and in vivo study. In the in vitro study, the release of ciprofloxacin from the cellulose membrane in the presence or absence of metal cations was measured using the dissolution test procedure. In the in vivo study, male ST Wistar rats and male volunteers were employed.
