[Myocarditis following mRNA vaccine].

This article presents the case of a 15-year-old adolescent presenting with myocarditis 4 days after receiving the 2nd dose of BNT162b2 mRNA vaccine (Comirnaty®) with no other identifiable cause. The main clinical symptom at presentation was chest pain. We found an elevated level of Troponin‑I with preserved left ventricular systolic function.

Changes on magnetic resonance tomography in the knee joints of marathon runners: a 10-year longitudinal study.

Objective: The aim of the study was to evaluate long-term damage in the internal structures of the knee joints of recreational long-distance runners.

Materials And Methods: Ten years after their participation in a baseline study concerning their knee joints, seven long-distance runners and one who had given up long-distance running were invited to participate in a repeat magnetic resonance imaging (MRI) investigation. The same evaluation criteria and the same technical equipment were used, and the results of the two investigations were compared.

Frequency and risk factors for meningioma in clinically healthy 75-year-old patients: results of the Transdanube Ageing Study (VITA).

Background: The prevalence of clinically silent intracranial tumors in specific populations is poorly researched. It is known that, in advanced age groups, the number of clinically manifest meningiomas constitute a small proportion of the actual number of cases. The goals of the current study were to determine the frequency of asymptomatic patients with meningioma in advanced age and to identify risk factors for meningiomas in this population.
