Neoplasia is characterised by abnormal regulation of the cell cycle. Cyclin D1 is a protein derived from the PRAD1, CCND1 or bcl-1 gene on chromosome 11q13, which is involved in both normal regulation of the cell cycle and neoplasia. In the G1 (resting) phase of the cell cycle, cyclin D1 together with its cyclin dependent kinase (cdk) partner, is(More)
Regulators of the cell cycle such as cyclin E play an important part in neoplasia. The cyclin E protein forms a partnership with a specific protein kinase. This complex phosphorylates key substrates to initiate DNA synthesis. Cyclin-dependent kinase inhibitors (CKIs) are able to suppress the activity of cyclin E. Various substances (including proteins(More)
STUDY DESIGN Case report of a lumbar extradural solitary fibrous tumor. OBJECTIVE To describe the clinical manifestations and successful treatment of a patient with solitary fibrous tumor of the lumbar spine. SUMMARY OF BACKGROUND DATA Solitary fibrous tumor usually occurs on the pleura but has been described in a growing number of sites. Although this(More)
It has been estimated that there may be as many as 150,000 healthcare associated infections (HCAI) in Australia each year, contributing to 7,000 deaths, many of which could be prevented through the implementation of appropriate infection control practices. Contact with contaminated hands is a primary source of HCAI. Intensive care staff have been identified(More)
The rate of nosocomial respiratory syncytial virus (RSV) infection was measured in a large pediatric hospital using an incidence density method. The at-risk days for nosocomial RSV were summed during a defined winter period in which there were 54 admissions with community-acquired RSV infection giving a rate of 2.9 cases per 1,000 at-risk days (95%(More)
Abnormalities of the cell cycle are present in all neoplasms. Cyclin E, which regulates the G1/S phase transition of the cell cycle, plays an important role in many different cancers. To further investigate the role of cyclin E in invasive breast ductal carcinomas in South African women, representative sections from 157 mastectomy and axillary clearance(More)
This study examined variability in handwashing policy between hospitals, variability in handwashing practices in nurses and how practice differed from policy in tertiary paediatric hospitals in Australia and New Zealand. Eight of the possible nine major paediatric hospitals provided a copy of their handwashing and/or central venous access device (CVAD)(More)
A 26 year old woman presented with a 4-year history of a gradually enlarging fluctuant mass on the left labium majus. Histologic examination following excision revealed myxoid liposarcoma. Following the diagnosis, further surgery was performed to ensure complete resection. Routine excision of draining lymph nodes is not advocated. Although rare, myxoid(More)

A 33-year-old woman presented with pruritus of the right ear and on examination was found to have 1 x 1 cm polypoid lesion in the external auditory canal. This was removed and histological examination revealed a well-circumscribed spindle cell lesion arranged in fascicles and whorls. Immunohistochemistry showed the tumor to be EMA-positive but S-100-,(More)
