Contribution of general medicine to perioperative and consultative care: an Australian metropolitan teaching hospital experience.

Little is known about the contribution of general medicine to perioperative and consultative care in Australia. A descriptive observational study was undertaken at a quaternary institution to evaluate the characteristics of perioperative and nonoperative consultations undertaken by general medicine. Results demonstrated patterns of engagement within a 'traditional' model of perioperative care and highlighted several opportunities for a redesign to a more proactive and collaborative cross-disciplinary model.

The family name as socio-cultural feature and genetic metaphor: from concepts to methods.

A recent workshop entitled "The Family Name as Socio-Cultural Feature and Genetic Metaphor: From Concepts to Methods" was held in Paris in December 2010, sponsored by the French National Centre for Scientific Research (CNRS) and by the journal Human Biology. This workshop was intended to foster a debate on questions related to the family names and to compare different multidisciplinary approaches involving geneticists, historians, geographers, sociologists and social anthropologists. This collective paper presents a collection of selected communications.

Use of the emotional Stroop to assess psychological trauma following traumatic brain injury.

PRIMARY OBJECTIVE: A modified Stroop task was used to investigate the hypothesis that implicit memory may be a possible mechanism for the development of acute stress disorder (ASD) in patients who have suffered a closed head injury. RESEARCH DESIGN: Three groups of hospital patients were compared within 1 month post-trauma: road traffic accident (RTA) patients with a brain injury (n = 15), RTA patients without a brain injury (n = 13) and a control group of orthopaedic and plastics patients (n = 15). METHODS AND PROCEDURES: Participants named colours of five types of words: RTA-related words, words related to hospitalization, obsessive-compulsive disorder (OCD) words, positive words and neutral words. Participants were also administered the Acute Stress Disorder Interview and the State-Trait Anxiety Inventory. MAIN OUTCOMES AND RESULTS: Both RTA patients with and without a brain injury demonstrated significant interference on words related to an RTA. Significant interference was unexpectedly observed for OCD words in RTA patients. Control patients did not display significant interference effects. CONCLUSIONS: Findings suggested that patients, both with and without explicit recall for an RTA, responded similarly on a task involving implicit memory for trauma. Possible implications for ASD and Post-traumatic Stress Disorder are discussed.

Triphasic MRI of pelvic organ descent: sources of measurement error.

PURPOSE: To identify sources of error when measuring pelvic organ displacement during straining using triphasic dynamic magnetic resonance imaging (MRI). MATERIALS AND METHODS: Ten healthy nulliparous woman underwent triphasic dynamic 1.5 T pelvic MRI twice with 1 week between studies. The bladder was filled with 200 ml of a saline solution, the vagina and rectum were opacified with ultrasound gel. T2 weighted images in the sagittal plane were analysed twice by each of the two observers in a blinded fashion. Horizontal and vertical displacement of the bladder neck, bladder base, introitus vaginae, posterior fornix, cul-de sac, pouch of Douglas, anterior rectal wall, anorectal junction and change of the vaginal axis were measured eight times in each volunteer (two images, each read twice by two observers). Variance components were calculated for subject, observer, week, interactions of these three factors, and pure error. An overall standard error of measurement was calculated for a single observation by one observer on a film from one woman at one visit. RESULTS: For the majority of anatomical reference points, the range of displacements measured was wide and the overall measurement error was large. Intra-observer error and week-to-week variation within a subject were important sources of measurement error. CONCLUSION: Important sources of measurement error when using triphasic dynamic MRI to measure pelvic organ displacement during straining were identified. Recommendations to minimize those errors are made.
