Abstract
Coronavirus disease 2019 (COVID‑19), caused by severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), was identified in December, 2019 in Wuhan, China. Since then, it has continued to spread rapidly in numerous countries, while the search for effective therapeutic options persists. Coronaviruses, including SARS‑CoV‑2, are known to suppress and evade the antiviral responses of the host organism mediated by interferon (IFN), a family of cytokines that plays an important role in antiviral defenses associated with innate immunity, and has been used therapeutically for chronic viral diseases and cancer. On the other hand, OncoTherad, a safe and effective immunotherapeutic agent in the treatment of non‑muscle invasive bladder cancer (NMIBC), increases IFN signaling and has been shown to be a promising therapeutic approach for COVID‑19 in a case report that described the rapid recovery of a 78‑year‑old patient with NMIBC with comorbidities. The present review discusses the possible synergistic action of OncoTherad with vitamin D, zinc and glutamine, nutrients that have been shown to facilitate immune responses mediated by IFN signaling, as well as the potential of this combination as a therapeutic option for COVID‑19.

Abstract
Bone Marrow Oedema Syndrome during childhood is a rare benign transient condition without clear pathophysiology. It usually resolves after conservative treatment, but resolution may exceed up to 8 months. A 12-year-old child with bone marrow oedema of the left foot which was diagnosed by magnetic resonance imaging (MRI) is reported. She presented with a six week subacute pain and mild swelling on the dorsal surface of the foot. Routine plain radiographs, blood tests, biochemical and serological tests were normal with the exception of serum Vitamin D levels that were reduced. The management of the child included partial weight-bearing, administration of anti-inflammatory drugs and supplementation of Vitamin D due to insufficient Vitamin D intake. After six months the child did not have any clinical symptoms and MRI showed complete resolution of the oedema. This is the first report of a juvenile bone marrow oedema correlated with hypovitaminosis D that was successfully treated with Vitamin D administration.
