Echocardiographic Findings in Children with Multisystem Inflammatory Syndrome from Initial Presentation to the First Years after Discharge.

Objective: We aimed to evaluate clinical and echocardiographic features of the children diag- nosed with multisystem inflammatory syndrome related to severe acute respiratory syndrome coronavirus-2 infection and determine early and mid-term cardiovascular outcomes.

Materials And Methods: We retrospectively evaluated 38 children who were diagnosed with multisystem inflammatory syndrome in our hospital between November 2020 and November 2021. Cardiovascular evaluations were performed during hospitalization, at the first, the second, and the third months after discharge, and then cardiac evaluation was repeated at 3-month intervals until a median of 24 weeks (range: 9-56 weeks).

A newborn with aortico-left ventricular tunnel mimicking sinus of valsalva aneurysm.

Aortico-left ventricular tunnel (ALVT) is a rare congenital cardiac anomaly and constitutes less than 0.1% of all congenital cardiac defects (1). ALVT is described as an abnormal connection between the ascending aorta and the left ventricle which originates commonly above the right sinus of valsalva.

Comparison of Sublingual and Intramuscular Administration of Vitamin B12 for the Treatment of Vitamin B12 Deficiency in Children.

Background: In most countries, contrary to some disadvantages, such as pain, relatively higher cost, and poor adherence to treatment, intramuscular (IM) route is still the primary treatment method for Vitamin B12 (VB12) deficiency. In recent years, because of these difficulties, new treatment methods are being sought for VB12 deficiency.

Objectives: We aimed to compare sublingual (SL) and IM routes of VB12 administration in children with VB12 deficiency and to compare the efficacy of methylcobalamin and cyanocobalamin therapy in these children.
