Abstract

To carry out a review of clinical characteristics, laboratory profiles, management and outcomes of patients with Kawasaki disease (KD) and macrophage activation syndrome (MAS). Medical records of patients treated for KD and MAS between January 1994 and December 2019 were reviewed. Patient demographics, clinical signs, laboratory values, coronary artery abnormalities, treatments and outcomes of patients with KD and MAS were recorded. We also performed a review published studies on the subject. Of the 950 cases with KD, 12 (1.3%; 10 boys, 2 girls) were diagnosed with MAS. The median age at diagnosis was 4 years (range 9 months-7.5 years). The median interval between onset of fever and diagnosis of KD was 11 days (range 6-30). Thrombocytopenia was seen in 11 patients. The median pro-brain natriuretic peptide value was 2101 pg/ml (range 164-75 911). Coronary artery abnormalities were seen in 5 (41.7%) patients; 2 had dilatation of the left main coronary artery (LMCA), 1 had dilatation of both the LMCA and right coronary artery (RCA), 1 had dilatation of the RCA and 1 had bright coronary arteries. All patients received IVIG as first-line therapy for KD. MAS was treated with i.v. methylprednisolone pulses followed by tapering doses o...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
