summary: The canid subfamily Caninae comprises all of the residing canids and their most up-to-date fossil family members. Their sister taxon is the Borophaginae with which they percentage an enormous amendment of the reduce carnassial, specifically the presence of a bicuspid talonid, which provides this the teeth an extra functionality in mastication. Contributing to this functionality is the growth of the posterolingual cingulum of M1 and improvement of a hypocone. The Caninae diverged from the Borophaginae within the narrowing and elongation of the premolars separated by way of diastemata and put in a shallow ramus and slim muzzle. those latter gains enable the Caninae to be well-known within the fossil checklist as early because the starting of the Oligocene (34 Ma) and represent facts that they signify a monophyletic staff

Z Associated with a degree of developmental delay (although most milestones are reached eventually). z Mild to moderate learning difficulties (IQ variable, but usually > 80). z Early feeding difficulties may be encountered. z There is an increased incidence of congenital anomalies (particularly cardiac lesions and duodenal atresia). z Some people with DS attend normal school initially and live fulfilling lives, including employment and relationships. z Life expectancy is reduced (particularly if there are associated congenital anomalies), but people with DS can now live into their fifties.

Children are not small adults Key differences are: z Size: This changes rapidly in the first year of life. An average birth weight of 3 kg increases to 10 kg by 1 year. Between the ages of 1 year and 10 years, weight can be predicted by the formula: Weight (kg) = 2 × (age [years] + 4). z Anatomy: younger children have a short, soft neck: the upper airway tends to obstruct if the neck is overextended in resuscitation. z Physiology: Normal physiological parameters (pulse, respiratory rate, blood pressure) change with age.

Z Septicaemia, meningitis and urinary tract infection are difficult to diagnose on history in infants, and should be considered in all young children with acute severe illness. Answers 41 z Diarrhoea and vomiting needs assessment of the duration and frequency of symptoms, fluid intake, urine output and presence of bile or blood in vomit or stool. z A history of consanguinity or previous sudden death in childhood may suggest an inborn error of metabolism. Q4: What clinical examination would you perform, and why?
