The development of clinical indicators for a consultation-liaison service

OBJECTIVE: The aim of this paper is to describe the development and implementation of clinical indicators in the consultation-liaison service at Royal Melbourne Hospital (RMH). METHOD: A working party lead by the University of Melbourne was established in 1998 to develop clinical indicators and a database for the RMH consultation-liaison service. Core parameters for measuring service functioning and six clinical indicators were developed. The system was implemented using a data collection form and computerised database operating within a system of regular clinical reviews. RESULTS: The clinical indicators, database and review system were found to be a feasible, useful and efficient addition to a consultation-liaison service at a major general hospital. CONCLUSIONS: Clinical indicators may be used within specialist psychiatry services to enhance clinical care and aid in service development and teaching.     

Virtual lesions and the not-so-modular brain.

Because lesions usually affect contiguous areas of the brain, cognitive neuropsychology has generally posited modularity of brain function, assuming that specific regions of the brain have specific dedicated functions. However, a review of 36 published functional neuroimaging studies suggests that functions are distributed over multiple regions. Or, in other words, specific brain regions are usually multifunctional. By a technique of "virtual lesions," I measure the contribution that regions of the brain make to tasks imaged in 36 PET experiments, and propose a new and more detailed interlink between neuropsychology and functional neuroimaging.     

Early report: comparison of breath-hold MR excretory urography, Doppler ultrasound and isotope renography in evaluation of symptomatic hydronephrosis in pregnancy

AIM: To compare assessment by MR excretory urography (MREU), Doppler ultrasound and isotope renography of women with symptomatic hydronephrosis in pregnancy and to define its cause.MATERIALS AND METHODS: Eleven women at 19-34 weeks of gestation were studied prospectively with gadolinium-enhanced breath-hold gradient echo MREU and transabdominal Doppler ultrasound compared with a 'gold standard' of isotope renography employing frusemide challenge. All studies were performed within 24 h, were reported independently in a blinded fashion and employed clearly defined criteria. Obstetric and infant outcomes were obtained.RESULTS: There were no adverse reactions to gadolinium administration in pregnancy and no adverse obstetric or infant outcomes. Three of the 11 women were unable to tolerate the complete MREU protocol. Ultrasound indices could not be used to predict ureteric obstruction as shown by isotope renography. MREU agreed with renographic findings in five of the six cases with obstruction and in two without obstruction. MREU directly demonstrated hydronephrosis to result from extrinsic compression of the ureter between the gravid uterus and iliopsoas muscle. CONCLUSION: MR excretory urography is a promising technique which affords equivalent functional and additional anatomical information to isotope renography. It is more accurate than Doppler ultrasound in the assessment of ureteric obstruction in pregnancy.Spencer, J. A. (2000). Clinical Radiology55, 446-453.     

Creation, Evaluation, and Continuing Assurance of Excellence of the Certified Surgical Specialist

A position paper on the subject of certified surgical specialists was published in 1966 under the direction of Professor Charles Wells of Liverpool, England. President John Terblanche of the International Federation of Surgical Colleges brought together leaders in surgical education from four nations (Australia, Japan, South Africa, United States) to update current “state-of-the art” views. Presentations were made at the 38th Congress of the International Society of Surgery, August 18, 1999 in Vienna, Austria. After careful review of the four presentations, it was clear that surgeons all over the world have made great improvements in the many facets of surgical education. Yet the advances remain spotty, with gaps noted when viewed from an international perspective.     

Skp2 protein expression in soft tissue sarcomas.

BACKGROUND: p45 S phase kinase-associated protein-2 (p45(skp2)), a member of the F-box family of proteins, is an important component of the Skp1-Cullin-F-box protein (SCF) ubiquitin-ligase complex (SCF(skp2)). The latter has been implicated in the ubiquitination and degradation of p27(kip1) (p27) and G(1)-S cell cycle progression. The expression and prognostic role of Skp2 in a large series of soft tissue sarcomas has not been previously investigated. METHODS: Clinicopathologic features and immunohistochemical expression of Skp2, p27, and Ki-67 proteins were studied in 182 cases of soft tissue sarcomas (American Joint Committee on Cancer stages II and III). Survival analyses were performed using the Kaplan-Meier method and the Cox regression model. RESULTS: The male to female ratio was 1.2:1, and the median age at the diagnosis was 53 years. The tumors were predominantly located in the lower extremities (n = 163; 90%) and had a median size of 9 cm. High Skp2 expression (> or = 10% of the cells) was identified in 68 tumors (37%), and was correlated with high grade histology (P =.002) and Ki-67 proliferative index (r = 0.44; P <.0001), but not with p27 expression (r = -0.02; P =.80). By univariate analysis, high Skp2 expression was associated with decreased metastasis-free, disease-free, and overall survival. In a multivariate model, high Skp2 expression was an independent predictor for decreased local recurrence-free, disease-free, and overall survival. CONCLUSION: These results indicate that Skp2 expression is associated with cell proliferation and a worse prognosis in soft tissue sarcomas. The lack of an inverse correlation between Skp2 and p27 suggests that additional molecular events associated with either Skp2 expression or p27 proteolysis may be operating in these tumors.     

Perceptions of social stigma and its effect on interpersonal relationships of young males who experience a psychotic disorder

Background:  People with psychotic disorders experience high levels of disability and impairment as a result of their illness. Difficulty in the area of social relationships poses a substantial problem with the majority of people with psychosis being socially isolated. Many of them experience an unmet need for services.
Methods:  A focus group was conducted with the aim of investigating the perceived experience of six young men who had a psychotic disorder to gain an understanding of the impact this had on interpersonal relationships.
Results:  The major themes identified were: (i) a significant decrease in the internal and external control of one's life at the onset of illness; (ii) the effects of labelling and stigma on interpersonal relationships; and (iii) the change in self perception that these effects bring.
Conclusion:  The implications of the findings for rehabilitation interventions are presented, specifically psychosocial group interventions addressing interpersonal relationships.     

Pediatric electrocardiograph abnormalities following Centruroides limpidus tecomanus scorpion envenomation.

Scorpionism is an endemic public health problem in Mexico [Hoffmann, C.C., 1936. La distribucion geografica de los alacranes peligrosos en la Republica Mexicana. Bol. Inst.

Scorpionism and serotherapy in Mexico. Toxicon 32 (9), 1015-1018]. In this prospective study, we assess cardiovascular disorders in children via electrocardiographic (ECG) recordings following envenomation by scorpion species Centruroides limpidus tecomanus found in the state of Colima, Mexico. We analyzed 113 cases between the ages of 5 and 14 years. Among the most frequent symptoms presented included local pain (99.1%) and paresthesia (75.2%), pruritus (36.3%), sialorrhoea (35.4%), and nystagmus (24.8%). Cardiovascular disorders were observed in 39.8% of cases, 71% of which were rhythm abnormalities. We find a significant association between the frequency of ECG alterations and age, whereby 8-9-year-old children are more likely to experience ECG alterations when compared with other tested age groups.
