Kyphoplasty is a minimally invasive procedure that is used to augment vertebral body strength. This technique has been commonly used to treat osteoporotic, vertebral body compression fractures. The technique was also used to augment painful metastatic vertebral fractures. ⋯ It can restore VBH and correct the kyphosis angle. While the increased amount of the injected PMMA led to its leakage, it did not contribute to restoration of the VBH or kyphosis correction. Therefore, one should avoid injection of excessive amounts of PMMA.

Non-accidental head injury ("shaken baby syndrome") is a major cause of death and disability in infants and young children, but it is uncertain whether shaking alone is sufficient to cause brain damage or an additional head impact is required. Accordingly, we used manual shaking in an ovine model in an attempt to answer this question since lambs have a relatively large gyrencephalic brain and weak neck muscles resembling a human infant. ⋯ Neuronal perikaryal APP was widely distributed in the brain and spinal cord, the first time such a diffuse neuronal stress response after shaking has been demonstrated, but axonal immunoreactivity was minimal and largely confined to the rostral cervical spinal cord at the site of maximal loading. No ischaemic-hypoxic damage was found in haematoxylin and eosin-stained sections.

We report a patient with McCune Albright syndrome with acromegaly and features predictive of difficult airway except a class I upper lip bite (ULB) test. Our patient, a 33-year-old woman, had a history of polyostotic fibrous dysplasia. ⋯ Our report suggests that the ULB test in people with acromegaly may act as an indicator of easy intubation in spite of other poor predictive signs. However, this finding needs further corroboration by a large study to evaluate the role of the ULB test in people with acromegaly.

Phrenic nerve stimulation is a technique whereby a nerve stimulator provides electrical stimulation of the phrenic nerve to cause diaphragmatic contraction. The most common indications for this procedure are central alveolar hypoventilation and high quadriplegia. This paper reviews the available data on the 19 patients treated with phrenic nerve stimulation in Australia to date. ⋯ Three patients had revisions due to mechanical failure. The remaining patients' notes were incomplete. These data suggest that phrenic nerve stimulation can be used instead of mechanical ventilators for long-term ongoing respiratory support.

Harvey Cushing and some Australian connections: part 1 - early life and work.
Before World War 1 both the United States of America and Australia had rather rudimentary medical systems. Enterprising practitioners in both countries tended to look to continental Europe (especially Germany) and the United Kingdom as places of medical renown. The outbreak of World War 1 changed this but also enabled doctors from both the United States and Australia to work in military hospitals in Europe. ⋯ Examples of these were the experiences of Harvey Cushing, a burgeoning American neurosurgeon, which he recounted in his diary. His commentary merits close inspection and analysis. An account of some of Cushing's Australian connections post World War 1 is given in Part 2 (in press).
