Diagnostic and Therapeutic Approach in Pediatric Pulmonary Abscess: Two Cases and Literature Review.

Pulmonary abscess is a rare but serious condition in pediatric patients, caused by severe pulmonary infection that leads to tissue destruction and necrosis. It can be classified as primary or secondary depending on the cause. Establishing an etiology in pediatric pulmonary abscesses is challenging, underscoring the essential role of advanced imaging techniques, such as computed tomography, in achieving an accurate diagnosis and differentiating among various conditions that may mimic lung abscess.

Diagnostic Challenges in Hemophagocytic Lymphohistiocytosis, a Rare, Potentially Fatal Disease: Two Case Studies.

Hemophagocytic lymphohistiocytosis (HLH) is a rare, and potentially fatal, syndrome, characterized by immune system dysregulation, with excessive activation of the macrophages and cytotoxic T cells. It can be classified into primary (genetic) and secondary (acquired) forms. HLH presents with fever, hepatosplenomegaly, cytopenia, and hyperferritinemia, with involvement of various organs.

The Role of Mannose-Binding Lectin and Inflammatory Markers in Establishing the Course and Prognosis of Community-Acquired Pneumonia in Children.

Background: Community-acquired pneumonia (CAP) is one of the most significant childhood diseases worldwide and a leading infectious cause of death in children. This study aimed to evaluate the prognostic value of the inflammatory markers-C-reactive protein (CRP) and procalcitonin (PCT)-and the polymorphic glycoprotein mannose-binding lectin (MBL), deficiency of which is associated with severe infections, in the determination of the optimal type and timing of therapeutic intervention for CAP in childhood.

Methods: Retrospective evaluation was conducted on a cohort of 204 children aged 4 months-17 years hospitalized with CAP.

The role of lung ultrasonography in predicting the clinical outcome of complicated community-acquired pneumonia in hospitalized children.

Aims: This study's objective was to analyze lung ultrasonography (LUS) characteristics in hospitalized pediatric patients with complicated community-acquired pneumonia (CAP). We hypothesized that LUS could be correlated with the clinical outcome in these cases.

Materials And Methods: In this retrospective study, we evaluated the LUS appearances (at admission and five days after the beginning of the treatment) and the progression of complicated CAP.

The Challenging Diagnosis of Pediatric Multisystem Inflammatory Syndrome Associated with Sars-Cov-2 Infection-Two Case Reports and Literature Review.

Severe acute respiratory coronavirus 2 (SARS-CoV-2) is a novel coronavirus discovered in 2019 that caused the coronavirus disease 2019 (COVID19). During the last year, over 70 million people were infected and more than 1.5 million people died.

The Prognostic Value of Mannose-Binding Lectin in Community-Acquired Pneumonia.

Community-acquired pneumonia is among the most widespread health issues in the pediatric population, affecting children around the world. Mannose-binding lectin is a component of the innate immune system that binds to carbohydrate fragments expressed by various microorganisms, thus aiding in their recognition and eventually activating the complement system through a specific pathway called "the lectin pathway". 204 pediatric patients whose mannose-binding lectin levels were evaluated at the beginning of infection were included in the study.

The role of glomerular morphometric features in pediatric podocytopathies - a single center study.

Podocytopathies represent a well-studied subgroup of glomerulopathies, being characterized by proteinuria due to damage or dysfunction of podocytes. Glomerular size in podocytopathies has been studied in different population, but only a few studies take in consideration the pediatric population. There are different methods to assess the glomerular size, but most of the studies report the maximal profile area as being the most accurate one.
