With thanks to Geoff Ferguson, Director of the Parent Infant Centre (www.infantmentalhealth.com) for the following explanation of the Acquarone scales:
The Acquarone Detection Scales for Early Relationships are observational scales that provide a powerful tool for assessing an infant’s capacity to form relationships and a mother’s ability to respond to her infant. The scales have been developed during several decades of clinical practice by Dr Stella Acquarone, who is also the author of several books on infant development and parent infant psychotherapy and Principal of the Parent Infant Clinic. The Parent Infant Clinic is a private service but does have some subsidised places for families with limited financial resources.
There are two scales, a 25 item scale for observations of the infant and a 13 item scale for observations of the mother. In each case observations are divided into four domains: interpersonal, sensorial, motor and affect. Within each domain observers are asked to note the frequency of certain behaviours. For example, when observing ‘calling’ the observer is looking for ‘facial expressions, noises or gestures that seek to produce an affectionate response from the partner’.
A concern about the infant or the mother might be raised if a particular behaviour was never observed, perhaps showing a difficulty in relating, or was constantly observed, perhaps showing a defensive repetitiveness. The scales can be used to establish a thorough observational benchmark against which later changes can be compared.

Steroids vs Steroids & Antivirals for Bell ’s Palsy
by Dr Tom Waterfield
Bell’s palsy is an idiopathic facial nerve palsy first described by Sir Charles Bell in 1830. It typically presents with a sudden onset of unilateral facial palsy. It presents as a unilateral lower motor neurone weakness ie. the forehead is also involved (if the forehead is not involved, this is an upper motor neurone weakness with a different aetiology and needs prompt referral for further investigation). The prognosis in true Bell’s is typically good with up to 90% of children recovering by 3 months of age1. The mainstay of management in children is supportive (artificial tears/patching). The convention – at least in adults – is for the early (within 72 hours of onset) use of oral prednisolone at a dose of 2mg/kg (max 60-80mg) for 5 days followed by a 5 day tapering dose2. The evidence base for this comes from large randomised controlled studies in adults3,4.
Evidence for the use of steroids alone
Two large double blind randomised control studies looking at over 1300 patients demonstrated that early use of Prednisolone orally significantly improved symptoms at 3 months (p<0.001) with a NNT of around 53,4. There are no similar studies in children and it is worth considering that children typically have a better prognosis than adults. Whilst prednisolone orally would be appropriate and safe for most children there may be instances where the risks of oral steroids could be considered too great to justify their use i.e. in a poorly controlled diabetic patient (which is a group in whom Bell’s palsy is more prevalent).
Evidence for the use of combined steroids and antivirals
In the last decade there has been an ongoing debate around the use of oral antiviral agents such as Aciclovir in the management of Bell’s Palsy. It is widely believed that Bell’s Palsy is due to an underlying Herpes Simplex infection and PCR studies have demonstrated concurrent HSV infection at the facial nerve in adult patients with Bell’s Palsy5. Despite this, good quality, large scale studies looking at the efficacy of oral antiviral agents have failed to demonstrate a benefit3,4.
The current evidence base for the medical management of Bell’s palsy comes predominantly from adult data3,4. Children typically have a milder illness with a quicker recovery than adults irrespective of the treatment chosen1. UpToDate would have us believe that the mainstay of medical management is the use of oral steroids at a dose of 2mg/kg(max 60-80mg) for 5 days followed by a 5 day taper. Additional antiviral treatment appears to be unnecessary with large-scale, high quality studies not showing a benefit. Smaller, lower quality studies have suggested additional antivirals may be useful and these could be considered on a case by case basis6,7. For example in a severe case (complete paralysis) with clinical evidence of concurrent Herpes Simplex infection it may be worth considering additional antiviral medication such as oral Aciclovir.
