Summary
Pediatricians identified a unique cluster of symptoms in children, later recognized as Kawasaki disease. Early recognition was challenging due to its novelty in medical literature.
Area of Science:
- Pediatrics
- Rheumatology
- Infectious Diseases
Context:
- The study details the initial encounters with a novel pediatric illness characterized by a unique symptom complex.
- The author, a pediatrician, observed patients with symptoms not matching existing medical literature.
- The initial cases were seen between 1961 and 1962 in Tokyo, Japan.
Purpose:
- To document and describe a previously unrecognized clinical syndrome in children.
- To highlight the diagnostic challenges posed by this new disease entity.
- To lay the groundwork for the formal description and naming of the condition.
Summary:
- The author encountered several pediatric patients exhibiting a consistent and unusual set of clinical signs and symptoms.
- These symptoms did not align with any known diseases described in medical texts at the time.
- The author's observations led to the eventual identification and publication of the 'Infantile Acute febrile Muco-cutaneous lymph node syndrome', now known as Kawasaki disease.
Impact:
- This work led to the formal recognition and naming of Kawasaki disease, a significant vasculitis affecting children.
- It provided the foundational clinical description for future research and diagnostic criteria.
- The early case series was crucial for raising awareness among the medical community about this distinct pediatric condition.

Receptor Tyrosine Kinases
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
cAMP-dependent Protein Kinase Pathways
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...
Transducer Mechanism: Enzyme-Linked Receptors
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

Receptor Downregulation in MVBs
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR activation may...

Diabetic Ketoacidosis l: Introduction
DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...
Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
