Preliminary experience of allied health assessments delivered face to face and by videoconference to a residential facility for elderly people

We investigated whether allied health assessments carried out via videoconferencing were comparable to assessments carried out face to face. Five allied health therapists (in dietetics, occupational therapy, physiotherapy, podiatry and speech pathology) conducted an assessment of 12 high-dependency residents both face to face and by videoconferencing. On a five-point Likert scale, the therapists' mean ratings for the efficiency and suitability of videoconferencing for assessment were significantly lower than for face to face. Their mean rating for the adequacy of their care plans was also significantly lower for videoconferencing than for face to face. However, in each case the dietician's assessments did not differ significantly between the two modalities. In 35 cases out of 60, two independent raters agreed that the therapists' care plans after the videoconferencing and face-to-face assessments were the same. However, the level of agreement between raters was only moderate (kappa=0.31). Despite the therapists' (natural) preference for face-to-face working, care plans formulated via videoconferencing were reasonably similar to those formulated in face-to-face assessment. Allied health assessments carried out by videoconferencing would therefore seem to be feasible.

Vascular endothelial growth factor-B and retinal vascular development in the mouse

Purpose: Vascular endothelial growth factor-A (VEGF-A) is crucial to retinal vascular growth, both normal and pathological. VEGF-B, recently characterized, is reported to be expressed in retinal tissues, but the importance of VEGF-B to retinal vascular development remained unknown. The aim of this study was to analyse retinal vascular growth in the Vegfb (-/-) knockout mouse. Methods: Retinal vascular growth was measured in Vegfb (-/-) knockout mice raised under normal conditions, and Vegfb (-/-) knockout mice with an oxygen-induced proliferative retinopathy. Wild type Vegfb (+/+) mice served as controls. Vessels were perfused with ink and retinal flatmounts secondarily labelled with FITC-lectin (BS-1, Griffonia simplicifolia ). Area and diameter of retinal growth and retinal vascular growth were recorded over days 0-20, and capillary density and mean diameter recorded from day 17 pups. Results: A variety of techniques confirmed that Vegfb (+/+) mice expressed VEGF-B and that VEGF-B expression was absent in Vegfb (-/-) mice. Vegfb (-/-) mice raised in room air showed no significant differences from Vegfb (+/+) controls. No differences were found in oxygen-induced retinopathy between Vegfb (-/-) and Vegfb (+/+) pups in either the extent of the initial oxygen-induced ablation, or in the regrowth of retinal vessels or vitreal (neovascular) sprouts; vitreal sprouts are important markers of the abnormal proliferative response, and are maximally expressed on day 17 in this model of oxygen-induced retinopathy. Conclusions: These results indicate that a lack of VEGF-B does not significantly affect development of the retinal vasculature under normal conditions, nor does it appear to affect the proliferative retinal responses seen in oxygen-induced retinopathy.

Vocational rehabilitation in psychiatry: A re-evaluation

Objective: To highlight the vocational gap in the provision of psychiatric rehabilitation, to outline the goals and conceptual framework of psychiatric rehabilitation, and to discuss rehabilitation interventions with specific reference to vocational rehabilitation and the evidence base for supported employment. Conclusions and service implications: Vocational psychiatric rehabilitation has been a neglected area of practice in Australian psychiatry. Psychiatric treatment needs to adopt a more balanced approach in the provision of a range of services, including vocational rehabilitation, in order to improve long-term outcomes for people suffering from psychiatric disability. A vocational focus should be included in psychiatric rehabilitation and better integration between mental health services and vocational services needs to take place. Supported employment is an evidence-based practice that is designed to help people with psychiatric disabilities participate as much as possible in the competitive job market.

Rehabilitation of pelvic floor muscles utilizing trunk stabilization

The pelvic floor muscles (PFM) are part of the trunk stability mechanism. Their function is interdependent with other muscles of this system. They also contribute to continence, elimination, sexual arousal and intra-abdominal pressure. This paper outlines some aspects of function and dysfunction of the PFM complex and describes the contribution of other trunk muscles to these processes. Muscle pathophysiology of stress urinary incontinence (SUI) is described in detail. The innovative rehabilitation programme for SUI presented here utilizes abdominal muscle action to initiate tonic PFM activity. Abdominal muscle activity is then used in PFM strengthening, motor relearning for functional expiratory actions and finally impact training. (C) 2003 Elsevier Ltd. All rights reserved.

A proposed new classification system for whiplash associated disorders - implications for assessment and management

The development of chronic symptoms following whiplash injury is common and contributes substantially to costs associated with this condition. The currently used Quebec Task Force classification system of whiplash associated disorders is primarily based on the severity of signs and symptoms following injury and its usefulness has been questioned. Recent evidence is emerging that demonstrates differences in physical and psychological impairments between individuals who recover from the injury and those who develop persistent pain and disability. Motor dysfunction, local cervical mechanical hyperalgesia and psychological distress are present soon after injury in all whiplash injured persons irrespective of recovery. In contrast those individuals who develop persistent moderate/severe pain and disability show a more complex picture, characterized by additional impairments of widespread sensory hypersensitivity indicative of underlying disturbances in central pain processing as well as acute posttraumatic stress reaction, with these changes present from soon after injury. Based on this heterogeneity a new classification system is proposed that takes into account measurable disturbances in motor, sensory and psychological dysfunction. The implications for the management of this condition are discussed. (C) 2004 Elsevier Ltd. All rights reserved.

Movement and motor development in ELBW infants at 1 year is related to cognitive and motor abilities at 4 years

A relationship between motor ability and cognitive performance has been previously reported. This study aimed to investigate the association between movement and cognitive performance at 1 and 4 years corrected age of children born less than 1000 g, and whether developmental testing of movement at 1 year is predictive of cognitive performance at 4 years. Motor development was assessed at both ages using the neurosensory motor developmental assessment (NSMDA) and motor development was classified as normal, or minimal, mild, moderate-severe dysfunction. Cognitive performance was assessed on the Griffith Mental Developmental Scale at 1 year and McCarthy Scales of Children's Abilities at 4 years. Subjects included 198 children of birthweight less than 1000 g. Of these 132 children returned for follow-up at the corrected ages of both 1 and 4 years. The 66 children not included had a slight increase in gestational age, while the mothers were younger and had a lower level of education. A significant association was found between NSMDA group classification at 1 year and cognitive performance at both 1 and 4 years (p

Telepaediatrics and diabetic retinopathy screening of young people with diabetes in Queensland

We have examined the feasibility of a telemedicine-enabled screening service for children and adolescents with diabetes in Queensland. There are approximately 1400 young people with diabetes in Queensland and only about two-thirds of them are screened in accordance with international guidelines. A regional retinal screening service was established using a non-mydriatic digital retinal camera. Seven centres volunteered to participate in the study. During a five-month pilot trial, 83 of the young people with diabetes who attend these centres underwent digital retinal screening (3.7%). Retinal images were sent via email to a paediatric ophthalmologist for review and results were returned via email. A copy of each participant's results was forwarded by mail to the referring diabetes doctor and the participant and family. The majority of the image files (96%) were rated as excellent or good. Only one participant was identified as having an abnormal result. Participants and their families expressed satisfaction with the digital retinal screening process.

Diode laser treatment of pre-threshold and threshold retinopathy of prematurity

Purpose: Retinopathy of prematurity (ROP) is a sight-threatening condition of premature infants. This study aimed to investigate the efficacy of diode laser photocoagulation in the treatment of pre-threshold and threshold ROP. Methods: A retrospective review was conducted of patients who underwent diode laser treatment for ROP by one author (GAG) from 1992 to 2000. During this time, 2137 babies

Glutamate transporter localization does not correspond to the temporary functional recovery and late degeneration after acute ocular ischemia in rats

Purpose: To determine whether the localization of retinal glutamate transporters is affected by retinal ischaemia and whether their ability to transport glutamate decreases with the progression of ischemic retinal and optic nerve degeneration. Methods: Retinal ischemia was induced in rats by acutely increasing the intraocular pressure (IOP, 110 mmHg/60 min). Reperfusion was permitted for periods up to 60 days post-ischemia. Functional evaluation was performed by monitoring the pupil light reflexes (PLRs) and electroretinograms (flash, flicker ERG and oscillatory potentials). Glutamate transporter localization and D-aspartate (glutamate analogue) uptake were assessed by immunohistochemistry. Results: Intense immunoreactivity for the retinal glutamate transporters (GLAST, GLT1, EAAC1 and EAAT5) was observed at all time points after the insult, despite severe retinal degeneration. D-aspartate was also normally accumulated in the ischemic retinas. Ten days post-operatively the PLR ratio (ratio = indirect/direct PLR = 34 +/- 7(.)5%) was significantly less than the pre-operative value (pre-op = 76(.)7 +/- 2 (.)6%, p < 0(.)05). However, 25 and 35 days post-operatively PLR ratios did not differ significantly from pre-operative values (44(.)4 +/- 6(.)9 and 53(.)8 +/- 9(.)6%, p > 0(.)05). Forty-five and 60 days post-operatively the PLR ratio declined again and was significantly lower than the pre-operative value (33(.)8 + 8(.)7 and 26(.)2 + 8(.)9%, p < 0(.)05). Statistical analysis revealed that all tested ERG components had significantly higher values at 32, but not at 42 and 58 days post-operatively when compared to the first time point recorded post-operatively (10 days). Conclusions: While retinal glutamate transport is compromised during an acute ischemic insult, consequent retinal recovery and degeneration are not due to a change in the excitatory amino acid transporter localization or D-aspartate (glutamate analogue) uptake. Rat retina and optic nerve are capable of spontaneous, but temporary, functional recovery after an acute ischemic insult. (C) 2004 Elsevier Ltd. All rights reserved.
