Role of optical coherence tomography in the early detection of macular thinning in rheumatoid arthritis patients with chloroquine retinopathy.

Background: Chloroquine and hydroxychloroquine are drugs that are primarily used for the treatment of malaria and are also recommended for treating connective tissue disorders, autoimmune diseases, and some dermatological and inflammatory diseases. Treatment with these drugs has potential risk for the development of retinopathy, clinically characterized by bilateral pigment changes in the macula, as one serious ocular complication. The aim of this research was to evaluate the parafoveal and perifoveal macular retinal thickness, as central foveal thickness in adult patients with rheumatoid arthritis (RA) on chloroquine therapy using optical coherence tomography (OCT).

Canine and human Dirofilaria infections in the Balkan Peninsula.

Dirofilaria immitis and Dirofilaria repens infections are mosquito-borne diseases, mainly of dogs. Both parasites are zoonotic, and they sometimes cause serious infections in humans. The aim of this short review was to examine the situation in the Balkan Peninsula, from where it is not always easy to obtain suitable data, often reported in journals and other publications difficult to be retrieved and with poor or no visibility.
