Mean platelet volume, in predicting severity of mitral regurgitation and left atrial appendage thrombosis.

The incidence of thromboembolism is higher in mitral regurgitation. Mean platelet volume (MPV), which is calculated automatically in the complete blood count tests, indicates platelet production, function and activation. Elevated MPV levels in cardiovascular diseases and some heart valve diseases have been shown before.

Introduction: Diabetic retinopathy (DR) is the most common complication and cause of visual impairment in diabetes patients. The pathogenesis is not fully understood, but several studies have suggested that inflammation plays an important role. The neutrophil-to-lymphocyte ratio (NLR) was defined as a novel potential marker to determine inflammation.

Non-syndrome patient with bilateral supernumerary teeth: Case report and 9-year follow-up.

The presence of supernumerary teeth, also known as hyperdontia, is the condition of having teeth in addition to the regular number of teeth. The occurrence of multiple supernumerary teeth is often found in association with syndromes such as Gardner syndrome, Anderson-Fabry disease, Ellis-van Creveld syndrome, Ehlers-Danlos syndrome, incontinentia pigmenti, and Tricho-rhino-phalangeal syndrome. Only a few examples of nonsyndromic multiple supernumerary teeth have been reported in literature.
