OBJECTIVE To analyze perpetrator and medical evidence collected during investigations of infant abusive head trauma (IAHT), with a view to (a) identifying cases where injuries were induced by shaking in the absence of any impact and (b) documenting the response of infant victims to a violent shaking event. METHOD A retrospective study was undertaken of IAHT cases investigated by the Queenslan...
The authors investigated the mechanisms underlying the head shaking shown by some patients with congenital nystagmus (CN). In order to improve visual function by head shaking, a patient with CN must have some visual acuity loss due to retinal image motion created by the nystagmus; an abnormal vestibulo-ocular reflex (VOR); and the head shaking must be correlated with the nystagmus. The authors ...
The role of alpha-1 adrenergic mechanism in the shaking stress-induced adrenocorticotropic hormone (ACTH), and plasma noradrenaline secretion and pressor response were investigated using conscious rats. We also studied whether or not central corticotropin releasing hormone (CRH) is involved in the shaking stress-induced ACTH secretion. The shaking stress caused significant elevations of plasma ...
The ontogenetic course of two cholinergically mediated central neuropharmacological effects, yawning and potentiation of head-shaking induced by D-amphetamine (5 mg/kg), was explored in developing rats. Physostigmine (0.1 mg/kg) and pilocarpine (4 mg/kg) evoke stereotyped yawning in neonatal rats, the effect declining in the middle of the second week of life. Both cholinomimetic drugs strongly ...
The shaking-B2 mutation was used to analyze synapses between haltere afferents and a flight motoneuron in adult Drosophila. We show that the electrical synapses among many neurons in the flight circuit are disrupted in shaking-B2 flies, suggesting that shaking-B expression is required for electrical synapses throughout the nervous system. In wild-type flies haltere afferents are dye-coupled to ...
This study examines people's response actions in the first 30 min after shaking stopped following earthquakes in Christchurch and Wellington, New Zealand, and Hitachi, Japan. Data collected from 257 respondents in Christchurch, 332 respondents in Hitachi, and 204 respondents in Wellington revealed notable similarities in some response actions immediately after the shaking stopped. In all four e...
