Cognitive behaviour therapy for the management of obsessive-compulsive disorder

Current research reflects conflict regarding best practice in the treatment of obsessive-compulsive disorder (OCD). The. present study reports on the psychological treatment of a 54-year-old woman diagnosed with OCD, and follows the implementation of pharmacological treatment. The study utilises both exposure and response prevention (ERP) and cognitive therapy (CT), although there was no attempt to compare these approaches in an experimental design. Measures of avoiding and neutralising behaviours were taken on three occasions across treatment. Measures were also taken of intrusive thoughts, appraisal of responsibility, and effective challenging, both across treatment and at follow-up. The results indicate that gains were made in addition to those reported following the implementation of medication. The results also suggest that the addition of CT to exposure and response prevention facilitates the extinction of neutralising behaviours.

Living with under-fives: a programme for parents with a mental illness

Parenthood is considered a major life role. Yet for people with a major mental illness, it is one that is fraught with difficulties and for which they receive the least support. Research on parenting and parenting programmes for people with a major mental illness is sparse and most of the papers presented do not provide a working model that can be easily replicated. This lack of support for parents or knowledge of working parenting programmes has often resulted in children being placed in care. Occupational therapists working in an Australian mental health service developed a two-stream programme which aimed to consolidate the parent/child relationship and enable the parents to develop effective parenting skills. This programme has a parents' educational stream and a stream with developmentally appropriate activities for the children. Observed outcomes have included the parents becoming more responsive to their children, increased treatment compliance, improved community access, and a decrease in the number of children in temporary foster care.

The leisure participation of clients with a dual diagnosis

People with a dual diagnosis experience disruption in carrying out their daily occupations. This article describes a study in which an occupational therapist explored the leisure participation of clients with a dual diagnosis. In-depth, semi-structured interviews were conducted with four outpatients from an alcohol and drug rehabilitation programme. Inductive analysis of the informants’ interviews identified two main themes: leisure as part of the recovery process and the barriers to leisure participation. This study provides support for the need to understand the leisure occupations of the clients with whom occupational therapists work. Further research is required to examine the interventions that assist clients with a dual diagnosis to develop meaningful leisure activities.

The leisure satisfaction of people with psychiatric disabilities

Leisure plays a dynamic role in peoples' lives and it would be useful to know how the satisfaction gained from leisure choices relates to personal and social adjustment, mental health and life satisfaction for people with psychiatric ability. Lloyd et al identify the extent of satisfaction derived from leisure activities for people with a mental illness and determine whether or not a standardized measure of leisure satisfaction can be applied to a population of people with mental illness.

Adult Growth Hormone Deficiency. What does the newest hormone replacement therapy do?

All patients with known pituitary or hypothalamic disease, or surgery or radiation treatment to the area could have growth hormone deficiency. Growth hormone deficiency in adults is an approved indication for recombinant growth hormone treatment in Australia. Diagnosis currently requires measurement of growth hormone response to insulin hypoglycaemia. Many patients have dramatic improvements in body composition, functional capacity and psychological wellbeing following recombinant human growth hormone replacement. (author abstract)

Stem cells in the aetiopathogenesis and therapy of rheumatic disease

Animal models of autoimmune disease and case reports of patients with these diseases who have been involved in bone marrow transplants have provided important data implicating the haemopoietic stem cell in rheumatic disease pathogenesis. Animal and human examples exist for both cure and transfer of rheumatoid arthritis, systemic lupus erythematosus (SLE) and other organ-specific diseases using allogeneic haemopoietic stem cell transplantation. This would suggest that the stem cell in these diseases is abnormal and could be cured by replacement of a normal stem cell although more in vitro data are required in this area. Given the morbidity and increased mortality in some patients with severe autoimmune diseases and the increasing safety of autologous haemopoietic stem cell transplantation (HSCT), pilot studies have been conducted using HSCT in rheumatic diseases. It is still unclear whether an autologous graft will cure these diseases but significant remissions have been obtained which have provided important data for the design of randomized trials of HSCT versus more conventional therapy. Several trials are now open to accrual under the auspices of the European Bone Marrow Transplant Group/European League Against Rheumatism (EBMT/EULAR) registry. Future clinical and laboratory research will need to document the abnormalities of the stem cell of a rheumatic patient because new therapies based on gene therapy or stem cell differentiation could be apllied to these diseases. With increasing safety of allogeneic HSCT it is not unreasonable to predict cure of some rheumatic diseases in the near future.

Can anticonvulsant drug therapy 'cure' epilepsy?

There is now evidence to show that, as time passes, epilepsy, even if untreated, tends to undergo spontaneous remission in a significant proportion of patients. The question therefore arises as to whether anticonvulsant drug therapy increases this chance of the patient with epilepsy ultimately entering a terminal remission which continues after the treatment is withdrawn, Le. whether anticonvulsant drug therapy itself may sometimes cure epilepsy. There are no well-designed studies available in the literature that provide a clear answer to this question. However, data from a number of investigations carried out for other purposes can be used to see whether contemporary anticonvulsant drug therapy is associated with higher rates of expected untreated terminal remission than those that apply for never-treated patients with epilepsy, or for those whose anticonvulsant treatment has probably been inadequate for various social or historical reasons. Despite the admitted uncertainties inherent in drawing conclusions from such material, there appears to be a reasonably consistent tendency for contemporary anticonvulsant drug treatment to be associated with a greater chance of achieving probable cure of epilepsy. Therefore it would appear premature to take the view that contemporary anticonvulsant drug therapy does no more than suppress epileptic seizures until epilepsy remits spontaneously, or fails to remit, with the passing of time.

Relationships between non-occupational cadmium exposure and expression of nine cytochrome P450 forms in human liver and kidney cortex samples

This study was undertaken to assess associations between age, gender, cigarette smoke and non-workplace cadmium exposure, and liver pathology and inter-individual variation in cytochrome P450 (CYP) expression in human tissues. Autopsy specimens of twenty-eight Queensland residents whose ages ranged from 3 to 89 years were analyzed for the presence of nine CYP protein isoforms by immunoblotting. All subjects were Caucasians and their liver cadmium contents ranged from 0.11 to 3.95 kg/g wet weight, while their kidney cadmium contents were in the range of 2 to 63 mug/g wet weight. CYP1A2, CYP2A6, CYP2D6, CYP3A4, and CYP3A5 were detected in liver but not in kidney, and CYP1A1 and CYP1B1 were not found in liver or kidney. Lowered liver CYP2C8/19 protein contents were found to be associated with liver pathology. Importantly, we show elevated levels of CYP2C9 protein to be associated with cadmium accumulation in liver. No mechanism that explains this association is apparent, but there are two possibilities that require further study. One is that variation in CYP2C9 protein levels may be, in part, attributed to an individual's non-workplace exposure to cadmium, or an individual's CYP2C9 genotype may be a risk factor for cadmium accumulation. A positive correlation was found between liver CYP3A4 protein and subject age. Levels of liver CYPIA2 protein, but not other CYP forms, were increased in people more exposed to cigarette smoke, but there was no association between CYPIA2 protein and cadmium. CYP2A6 protein was found in all liver samples and CYP2A6 gene typing indicated the absence of CYP2A6 null allele (CYP2A6(D)) in this sample group, confirming very low prevalence of homozygous CYP2A6(D) in Caucasians. CYP2A6 gene types W/W, WIC, and CIC were not associated with variations in liver microsomal CYP2A6 protein. CYP2D6 protein was absent in all twenty-five kidney samples tested but was detectable in liver samples of all but two subjects, indicating the prevalence of the CYP2D6 null allele (CYP2D6(D)) in this sample group to be about 7%, typical of Caucasian populations.

Early Australian experience with infliximab, a chimeric antibody against tumour necrosis factor-alpha, in the treatment of Crohn's disease: is its efficacy augmented by steroid-sparing immunosuppressive therapy?

Background: Tumour necrosis factor-alpha (TNF-alpha) plays an important role in the pathology of Crohn's disease. Infliximab, a chimeric antibody against TNF-alpha, has been shown in controlled clinical trials to be effective in two-thirds of patients with refractory or fistulating Crohn's disease. The factors that determine a clinical response in some patients but not others are unknown. Aims: To document the early Australian experience with infliximab treatment for Crohn's disease and to identify factors that may determine a beneficial clinical response. Methods: Gastroenterologists known to have used infliximab for Crohn's disease according to a compassionate use protocol were asked to complete a spreadsheet that included demographic information, Crohn's disease site, severity, other medical or surgical treatments and a global clinical assessment of Crohn's disease outcome, judged by participating physicians as complete and sustained (remission for the duration of the study), complete but unsustained (remission at 4 weeks but not for the whole study) or partial clinical improvement (sustained or unsustained). Results: Fifty-seven patients were able to be evaluated, with a median follow-up time of 16.4 (4-70) weeks, including 23 patients with fistulae. There were 21 adverse events, including four serious events. Fifty-one patients (89%) had a positive clinical response for a median duration (range) of 11 (2-70) weeks. Thirty patients (52%) had a remission at 4 weeks, 10 of whom had remission for longer than 12 weeks. Forty-two per cent of fistulae closed. Sustained remission (P = 0.065), remission at 4 weeks (P = 0.033) and a positive clinical response of any sort (P = 0.004) were more likely in patients on immunosuppressive therapy, despite there being more smelters in this group. Conclusion: This review of the first Australian experience with infliximab corroborates the reported speed and efficacy of this treatment for Crohn's disease. The excellent response appears enhanced by the concomitant use of conventional steroid-sparing immunosuppressive therapy.

Assessment and management of dysphagia following pharyngolaryngectomy with free jejunal interposition: A series of eight case studies

The physiological and structural deficits contributing to swallowing complications in the pharyngolaryngectomy patient population are not homogeneous. Consequently, a team approach, involving medical investigations as well as clinical and radiological assessments of swallowing, is necessary to facilitate diagnosis of the underlying impairment and assist the medical/surgical and speech pathology team members in the process of individualizing the management plan for each patient. In the present study, the clinical assessment and management of eight pharyngolaryngectomy patients who presented with a decline in swallowing function unrelated to immediate postsurgical effects or direct effects of radiotherapy are reported. Clinical and radiological investigations revealed a heterogeneous group of factors contributing to their swallowing impairments and disability levels, including difficulty with graft and anastomotic patency and graft motility, impaired lingual coordination, increased bolus transit time, nasal and oral regurgitation, patient distress, and recurrence. Variation between the cases supported the need for differential intervention and management plans for all eight patients. Ratings of perceived swallowing disability, handicap, and well-being/distress levels at initial assessment and again six months following dysphagia intervention revealed a pattern of reduced levels of impairment, functional disability, and overall patient distress levels following informed intervention. The present case study data highlights the key role thorough clinical and radiological investigations play in the process of diagnosing the factors contributing to dysphagia and guiding the management of the resultant swallowing disability in the pharyngolaryngectomy population.
