The influence of selective vitamin D receptor activator paricalcitol on cardiovascular system and cardiorenal protection

The ubiquitous distribution of vitamin D receptors in the human body is responsible for the pleiotropic effects of vitamin D-receptor activation. We discuss the possible beneficial effects of a selective activator of vitamin D receptor, paricalcitol, on the cardiovascular system in chronic heart failure patients and chronic kidney patients, in light of new trials. Paricalcitol should provide additional clinical benefits over the standard treatment for chronic kidney and heart failure, especially in cases of cardiorenal syndrome.

A Foreign Body (Toothbrush) in the Esophagus of a Patient with Hiatal Hernia

Toothbrush ingestion is rare and most commonly seen in patients with psychiatric comorbidities and in young women with a medical history of eating disorders who try to induce emesis. Long ingested objects, such as a toothbrush, cannot pass the gastrointestinal tract spontaneously and require endoscopic removal or even a surgical approach in cases of unsuccessful endoscopic removal or complication development. We present a case of a 71-year-old male with hiatal hernia without psychiatric or neurological comorbidity who accidentally ingested a toothbrush during oral hygiene routine. After X-ray confirmation, the toothbrush was removed endoscopically.
