Multisystem Inflammatory Syndrome in Children (MIS-C), Possibly Due to COVID-19 mRNA Vaccination.

Multisystem inflammatory syndrome in children (MIS-C) is a potentially life-threatening childhood disease caused by SARS-CoV-2 infection, manifested by the persistence of fever and multi-organ dysfunction, elevated inflammatory markers, and the lack of an alternative diagnosis. It is still unknown if vaccination can precipitate or abrogate MIS-C or if a natural infection preceding or occurring at the time of vaccination plays any role. We present one case of MIS-C in a 16-year-old girl who was fully immunized against COVID-19 (Pfizer), with the second dose received three weeks prior to onset of the disease.

Coincidental or mimicking acute appendicitis secondary to MIS-C associated with SARS-CoV-2: A case report.

The predominant organic system involved in multisystem inflammatory syndrome in children associated with COVID-19 is the gastrointestinal system, which is observed in almost 90% of patients. Gastrointestinal symptoms can mimic acute appendicitis. There have been a few cases of misdiagnosed multisystem inflammatory syndrome in children associated with SARS-CoV-2 as appendicitis, and a few concomitant cases of a multisystem inflammatory syndrome associated with acute appendicitis during the COVID-19 pandemic.

Aseptic meningitis in multisystem inflammatory syndrome in children associated with coronavirus disease 2019: a case report.

Background: As the coronavirus disease 2019 infections are still ongoing, there is an increasing number of case reports and case series with various manifestations of life-threatening multisystem inflammatory syndrome in children . Our case aims to remind all providers to scrutinize for clinical manifestations, including neurological symptoms, which may mimic aseptic meningitis.

Case Presentation: A 5-year-old Albanian male child with obesity was admitted to the pediatric intensive care unit due to persistent fever, headache, vomiting, abdominal pain, mucocutaneous manifestations, and fatigue.

Peripheral primitive neuroectodermal tumor: a case report.

Background: Primitive neuroectodermal tumors are extremely rare and highly aggressive malignant small round cell tumors that arise from the primitive nerve cells of the nervous system or outside it. These tumors share similar histology, immunohistologic characteristics, and cytogenetics with Ewing's sarcoma. Peripheral primitive neuroectodermal tumors of the chest wall are rare malignant tumors seen in children and young adults.

Celiac Disease in Kosovar Albanian Children: Evaluation of Clinical Features and Diagnosis.

Background: Celiac disease is an immune-mediated disorder characterized by variable clinical manifestations, specific antibodies, HLA-DQ2/DQ8 haplotypes, and enteropathy.

Objectives: The aim of this study was to present the clinical spectrum and patterns of celiac disease in Kosovar Albanian children.

Methods: A cross-sectional retrospective study was performed with Albanian children aged 0-18 years, treated for celiac disease in the Pediatric Clinic, University Clinical Center of Kosovo from 2005 to 2016.
