Features of umbilical and paraumbilical hernias. Paraumbilical hernias are situated just above the umbilicus, and unlike umbilical hernias, have no potential for spontaneous closure.

Schematic representation of the behavioural spectrum in Tourette’s syndrome: the size of each area is proportional to the estimated prevalence of the symptoms; the background colour intensity is proportional to the complexity of the clinical presentation

Diagram depicting emmetropic (normal), myopic, and hypertropic eyes. In myopia, light focuses in front of the retina, usually because of a long axial length, a steep corneal curvature, or a combination of the two. In hypermetropia, the converse is true—light focuses behind the retina, usually because of a short axial length, a flat corneal curvature, or a combination of both

Pathogenesis of type 2 diabetes with obesity. Genetic/environmental factors confer susceptibility to weight gain, insulin resistance, and pancreatic β cell dysfunction. Excess adiposity promotes insulin resistance, which is initially compensated for by increased insulin concentrations. When these are unable to overcome the insulin resistance then hyperglycaemia develops. Continued deterioration of β cell function causes further impairment of glucose homoeostasis into type 2 diabetes
