A cluster of pediatric vaccine-induced immune thrombotic thrombocytopenia-like cases with thrombosis and thrombocytopenia following respiratory infections-case series.

Background: Adenoviral vector COVID-19 vaccine-induced immune thrombotic thrombocytopenia (VITT) is a heparin-independent platelet-activating disorder. An increasing number of VITT-like disorders without previous vaccination are being identified.

Key Clinical Question: To explore the association of the pediatric cluster of postinfectious thrombosis and thrombocytopenia with VITT-like disorders.

Non-inferiority of liquid thyroxine in comparison to tablets formulation in the treatment of children with congenital hypothyroidism.

Objectives: The aim of the current prospective randomized control study was to assess efficacy, safety, and non-inferiority of a new liquid L-thyroxine formulation dissolved in glycerol and water (T4 drops, produced by a Greek pharmaceutical Company, Uni-Pharma, Athens, Greece) in comparison to the standard Tablets form (T4 tablets, Uni-Pharma, Athens, Greece) in the substitutive treatment of children with congenital hypothyroidism (CH).

Methods: Thirty-nine children with CH, aged 3-12 years old, were enrolled in the study, after parental Informed Consent has been obtained, while three patients were lost from follow-up. At baseline, all participants had normal thyroid-stimulating hormone (TSH) and Free T4 values.

Non-alcoholic fatty liver infiltration in children: an underdiagnosed evolving disease.

Non-alcoholic fatty liver disease (NAFLD) constitutes the most common liver disease, one that is still underdiagnosed in pediatric populations (as well as in the general population), this due to the progressive increase in childhood obesity observed both in developed and developing countries during the last few decades. The pathophysiology of the disease has not been thoroughly clarified yet. The condition displays common pathways in adults and children; however, there are age-related differences.

Acute hepatitis in a child heterozygous for the I259V MEFV gene variant.

Familial Mediterranean Fever (FMF) is a systemic auto-inflammatory disease characterized by recurrent episodes of fever accompanied by synovial, serosal and/or cutaneous inflammation. Liver involvement has been described mainly in patients with paired FMF gene mutations, i.e.

Soy- and rice-based formula and infant allergic to cow's milk.

Soy milk formula has limited medical indications for infants feeding, although in several parts of the world it has been used as a source of nutrition in a large number of children. It used to be the main alternative feeding for infants allergic to cow's milk who did not breastfeed before the introduction of extensively hydrolyzed formulas. Although there is a debate, the fact that some children are allergic to soy or some children with cow's milk allergy can present with concomitant soy allergy, restricted the use of soy formulas for treatment of infants allergic to cow's milk.

Flow cytometric analysis of the CD4+ TCR Vβ repertoire in the peripheral blood of children with type 1 diabetes mellitus, systemic lupus erythematosus and age-matched healthy controls.

Background: Data regarding the quantitative expression of TCR Vβ subpopulations in children with autoimmune diseases provided interesting and sometimes conflicting results. The aim of the present study was to assess by comparative flow cytometric analysis the peripheral blood CD4+ TCR Vβ repertoire of children with an organ-specific autoimmune disorder, such as type 1 diabetes mellitus (T1DM), in comparison to children with a systemic autoimmune disease, such as Systemic Lupus Erythematosus (SLE) in comparison to healthy age-matched controls of the same ethnic origin. The CD4+ TCR Vβ repertoire was analysed by flow cytometry in three groups of participants: a) fifteen newly diagnosed children with T1DM (mean age: 9.

The Role of BCL2 Family of Apoptosis Regulator Proteins in Acute and Chronic Leukemias.

The disturbance of apoptosis molecular signaling pathways is involved in carcinogenesis. BCL2 family of proteins is the hallmark of apoptosis regulation. In the last decade, new members of BCL2 gene family were discovered and cloned and were found to be differentially expressed in many types of cancer.

Congenital cataracts, facial dysmorphism, and neuropathy syndrome.

Congenital cataracts, facial dysmorphism, and neuropathy syndrome is a delineated genetic disease exclusively manifested in the Roma population. The pattern of inheritance is autosomal recessive, and a causative mutation is evident in the CTDP1 gene. Affected patients display congenital cataracts, microcornea, peripheral neuropathy, mild facial dysmorphism, hypogonadism, and psychomotor delay.
