A retrospective study of zygomatico-orbital complex and/or zygomatic arch fractures over a 71-month period

Background/Aim: The aim of this retrospective study was to evaluate the epidemiology, treatment, and complications of zygomatico-orbital complex (ZOC) and/or zygomatic arch (ZA) fractures either associated with other facial fractures or not over a 71-month period. Material and methods: This survey was performed in three hospitals of Ribeirao Preto in Sao Paulo, Brazil, from August 2002 to July 2008. The records of 1575 patients with facial trauma were reviewed. There were 140 cases of ZOC and ZA fractures either associated with other facial fractures or not. Data regarding gender, age, race, addictions, day of trauma, etiology, signs and symptoms, oral hygiene condition, day of initial evaluation, hospital admission, day of surgery, surgery approach, pattern of fractures, treatment performed, post-operative antibiotic therapy, day of hospital discharge, and post-operative complications were collected. The data were subjected to descriptive statistical analyses. Results: The most frequent fractures affected Caucasian men and occurred during the fourth decade of life. The most frequent etiology was traffic accident, and symptoms and signs included pain and edema. Type I fractures were the main injury observed, and the treatment of choice was always rigid internal fixation. Post-operative antibiotic therapy was solely employed when there was an indication. Complications were observed in 13.1% of the cases. Conclusions: The treatment protocol yielded suitable post-operative results and also showed success rates comparable to published data around the world.

ON THE COMPOSITE OF THREE IRREDUCIBLE MORPHISMS IN THE FOURTH POWER OF THE RADICAL

We study here the nonzero composite of three irreducible morphisms between indecomposable modules lying in the fourth power of the radical.

Architectural expression of liturgy and doctrine in the Eastern churches of the fourth to sixth centuries: towards a theologically contextual typology

Many scholars of Byzantine architecture have theorised about the reasons for church form and structure, with most relating them to sources in pagan architecture or local traditional construction methods (Krautheimer, Crowfoot, Ward-Perkins, Mango and Hill); to aspects of provincialism, regional independence or location peripheral to empire (Megaw, Delvoye, Wharton), or to environmental constraints such as frequent earthquakes (Curcic). But just as the wording of the various creeds and ecumenical statements responded to aspects of contemporary non-orthodox beliefs or "heresies", so did the theological debate inform the liturgical practices and consequently church planning. It could be expected that these responses would also be reflected in the architectural approach to form and symbolism. Thus a contextual typological framework is proposed, based on the association of different architectural approaches to church planning and form in the 4th to the 6th centuries with the contemporary doctrinal disputes over the true nature of Christ.

Depression and bone mineral density in a community sample of perimenopausal women: Geelong Osteoporosis Study

Objective: Reduced bone mineral density (BMD) in women with a history of depressive disorders has been shown in some, but not all studies. This study investigated the association between self-reported depression and BMD in an age-stratified community sample of perimenopausal women residing in the South-Eastern region of Australia.

Design: Symptoms of depression in the year between July 2000 and July 2001 were ascertained by a self-report questionnaire based on Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. Women in the perimenopausal group who had undergone a BMD total hip and spine assessment within the 12-month period after the depression assessment were included in the analysis, resulting in a sample of 78 women aged 45 to 60 years.

Results: In this sample, 14 women were identified as depressed. There was no difference in age, hormone therapy (HT) use, or unadjusted BMD at the total hip or spine between the depressed and nondepressed women (P = 0.14, 0.89, 0.57, and 0.70, respectively), but the depressed women tended to be heavier [depressed (median weight, interquartile range = 80 kg, 66-94) vs nondepressed (72 kg, 61-80) P = 0.06]. Whereas there was no significant difference in age-, HT-, and weight-adjusted BMD at the spine [depressed (mean ± SE = 1.21 ± 0.05) vs nondepressed (1.28 ± 0.03 g/cm2) P = 0.18], adjusted BMD at the total hip for the depressed women was 7.8% lower than for the nondepressed [depressed (mean ± SE = 0.957 ± 0.038) vs nondepressed (1.038 ± 0.023 g/cm2) P = 0.04].

Conclusions: These results suggest that in perimenopausal women, self-reported depression is associated with lower BMD at the hip.

Warrock collection: original line drawings by fourth year Deakin University architecture students of the Warrock Homestead, a local heritage listed property in Victoria

This collection includes the original line drawings by fourth year Deakin University architecture students of a well known local heritage listed property, the Warrock homestead. The Warrock homestead consisted of detailed original timber structures of the 19th century. The drawings are the result of a conservation project funded by the Commonwealth Government of Australia National Estate Grants program. In 1999 a further deposit of original reports relating to individual buildings on the property was received. The collection consists of monographs, photographs and photograph negatives, architectural drawings, VHS tapes and ephemera.

Australia's health 1994 : the fourth biennial report of the Australian Institute of Health and Welfare

Australia's Health is the most comprehensive and authoritative source of national information on health in Australia. Australia's Health is published mid-year in even-numbered years and provides national statistics and related information that form a record of health status, service provision and expenditure in Australia.
