SBS: Useful references to development of terminology

Shaken baby syndrome theory, by whatever name it morphs into, which holds that a small dead child displaying certain limited soft tissues pathologies but no other injuries was shaken to death by the last person who held the child when he or she was conscious. Of all the questioned forensic theories and practices, this is the one I would put at the top of the list for the threshold examination. Of all the currently questioned practices, this is the only one asserted by a respectable minority of specialists to be completely invalid. While a vitriolic dispute continues between the pro and con groups, defendants continue to be sentenced to exceedingly long prison terms based on the theory. While the theory’s supporters accuse the doubters of profiting from defending baby-killers, the doubters label the supporters as zealots lacking any knowledge of physics or of the scientific method. It is long past time that an authoritative body outside the adversarial system examined the underpinnings of the theory and published its results.

Response:

The Shaken Baby Syndrome is a fabricated diagnosis. It was fabricated by doctors who do not understand the pathophysiology of haemostasis and osteogenesis.
Editor,
Vitamin K is a fat soluble vitamin and is a co-factor for an enzymatic conversion of
glutamic acid (Glu) to γ-carboxyglutamic acid (Gla) by γ-glutamyl-carboxylase  and
along with other essential nutrients including Vitamins C and D is  necessary for the
biological activity of the blood coagulation factors and the formation of bone.
A reduction or abnormality of Vitamin K is known to cause  Haemorrhagic Disease of the New Born and fractures in children with Cystic Fibrosis.
Subdural and retinal hemorrhages, encephalopathy and fractures in children which have hitherto been attributed to Shaken Baby Syndrome, Non-accidental injury, Abusive Head Trauma or Inflicted Brain Injury are features of Vitamin K and/or C deficiency and other essential nutrients – Innis’ Syndrome would be an appropriate name change for this combination of signs and symptoms.
Commencing in the mid 20th Century with the publication of a report by an American Radiologist on fractures and haemorrhages in infants1  a Neurosurgeon in England suggested that the cause of the lesions was  violent shaking of the infant by an adult2  a claim echoed by the Radiologist3.  This was the first mention of the “Shaken Baby Syndrome”.
When it was realized that skull fractures could not be explained by shaking, a Professor of Paediatrics in England suggested that a violent impact of the skull against a hard object was the most probable cause of this type of fracture4.  The Shaken Baby Syndrome morphed into “Shaken –Impact  Syndrome”.
Retinal haemorrhages  seen in these children were claimed to be conclusive proof of abuse and Ophthalmologists  added  acceleration –deceleration of the head  as it is violently rotated by the abuser as the cause of the retinal haemorrhages5.
Throughout Academia the current teaching is,  it is the  triad of subdural and retinal haemorrhage with brain damage, as well as the characteristics of each of these components that allow a reconstruction of the mechanism of injury, and assessment of the degree of force employed. Academics claim it is the application of rotational acceleration and deceleration forces to the infant’s head which causes the brain to rotate in the skull. Abrupt deceleration, it is claimed, allows continuing brain rotation until bridging veins are stretched and ruptured, causing a thin layer of subdural haemorrhage on the surface of the brain6-17.
Maguire et al;17  claim that their review, the largest of its kind, offered for the first time, a valid “statistical probability of Inflicted Brain Injury” when certain key factors are present. The “key factors”  included retinal hemorrhages and apnoea both of which are known to be associated with vitamin K deficiency18,19 .
