A Case of Multisystem Inflammatory Syndrome in Children Presenting as Acute Appendicitis and Pancreatitis.

Multisystem Inflammatory Syndrome in Children (MIS-C) is characterized by an inflammation with fever, elevated inflammatory markers, conjunctivitis, rash, impaired coagulation, gastrointestinal symptoms and cardiac abnormalities that may progress to multiorgan failure. The presence of a positive COVID-19 antigen via a PCR test, serological testing for antibodies or close contact with a person diagnosed with COVID-19 helps differentiate MIS-C from other diseases. Gastrointestinal symptoms are recognized to be associated with COVID-19 infection or MIS-C in children, presenting as abdominal pain, gastrointestinal infection with watery stools, appendicitis, ileitis, pancreatitis and hepatitis, confusing the diagnosis with other gastrointestinal diseases.

Adverse Reactions to Intravenous Immunoglobulins - Our Experience.

Background: Adverse reactions to intravenous immunoglobulins (IVIG) are divided by organ system involved, or by timing of onset-immediate which occur during infusion usually rate-related, true IgE-mediated anaphylaxis and delayed reaction which occur hours to days after the infusion.

Aim: To describe the adverse events of patients given IVIG infusions.

Methods: Total number of patients receiving IVIG was 41 with 25 males (60.

Gene Alterations in Children Born Small for Gestitional Age (SGA).

Background: Small for gestational age (SGA)-born children are a heterogeneous group with few genetic causes reported. Genetic alterations in the IGF1 receptor (IGF1R) are found in some SGA children.

Aim: To investigate whether alterations in gene are present in SGA born children.

Gene Alterations in Small for Gestational Age (SGA) Children.

Background: Small for gestational age children (SGA) is born on term with BW and or BL of -2.0 standard deviation score (SDS). SGA children have an increased risk of being short, developing DM, and cardiovascular and cerebrovascular disease.

Metabolic Profiles in Obese Children and Adolescents with Insulin Resistance.

Background: In the past several decades, the increasing frequency of overweight and obese children and adolescents in the world has become a public health problem. It has contributed significantly to the already high tide of diabetes, cardiovascular and cerebrovascular diseases.

Aim: To investigate the frequency of insulin resistance and to evaluate the metabolic profile of insulin resistant and non-insulin resistant obese children and adolescents.

Genetic and demographic features of X-linked agammaglobulinemia in Eastern and Central Europe: a cohort study.

Primary immunodeficiency disorders are a recognized public health problem worldwide. The prototype of these conditions is X-linked agammaglobulinemia (XLA) or Bruton's disease. XLA is caused by mutations in Bruton's tyrosine kinase gene (BTK), preventing B cell development and resulting in the almost total absence of serum immunoglobulins.
