Depression and anxiety in rheumatoid arthritis: the role of perceived social support.

BACKGROUND: Rheumatoid arthritis is a common, disabling, autoimmune disease with significant psychiatric sequelae. AIMS: We aimed to identify the prevalence of depression and anxiety in patients with rheumatoid arthritis attending hospitals, and to elucidate the role played by illness variables, disability variables and psychosocial variables in predicting levels of depression and anxiety. METHODS: We assessed depression, anxiety, arthritis-related pain, arthritis-related disability and perceived social support in 68 adults with rheumatoid arthritis. RESULTS: Sixty-five per cent of patients had evidence of depression (37.5% moderate or severe) and 44.4% had evidence of anxiety (17.8% moderate or severe). Both depression and anxiety were highly correlated with several measures of arthritis-related pain and functional impairment. After controlling for age, gender, marital status and duration of arthritis, perceived social support was a highly significant independent predictor of both depression and anxiety. CONCLUSIONS: These findings suggest that increasing social support may be particularly important in the management of depression and anxiety in rheumatoid arthritis.

Comparative evaluation of image segmentation methods for volume quantitation in SPECT.

A wide variety of image segmentation techniques have been proposed for the measurement of organ or lesion volumes in SPECT images. Evaluation of the relative performance of the various methods is difficult due to wide variations in system response characteristics, size, shape, and contrast of the imaged objects, and image acquisition and processing techniques. Selected image segmentation methods for volume quantitation in SPECT were applied to a set of simulated SPECT images containing objects ranging in volume from 1.8 to 113.1 cc. The specific segmentation methods included: (1) operator drawn regions of interest, (2) count-based methods, (3) three levels of fixed thresholds, (4) an adaptive threshold (GLH method), (5) a two-dimensional (2-D) edge detection method, and (6) a three-dimensional (3-D) edge detection method. In general, the 3-D edge detection method required minimal operator intervention while providing the most accurate and consistent estimates of object volume across changes in object contrast and size.

Early pregnancy loss: how do men feel?

One in five pregnancies (20%) end in miscarriage. A specialized early pregnancy loss clinic to provide dedicated medical advice and support was established at the Rotunda Hospital in July 2002. A qualitative pilot study was conducted in July 2002 to assess the emotional response of male partners and also to establish if sufficient support services are provided for them. Ten consecutive couples attending the clinic 6-8 weeks following early pregnancy loss were included in the study. The partners were asked to complete a questionnaire with open and closed questions and return in the envelope provided. Nine questionnaires were returned. The average age of men attended was 28.6 years (range 20-39). The feelings described by men were typical of the grief and bereavement process. All wanted more time for discussion with doctors. They felt marginalized and although they felt support services for their partner were adequate, they felt that more support services for male partners should be provided. Based on these research findings, the specialized early pregnancy loss clinic is being developed to partner's needs and expectations. The appointment letter sent to the women now specifically states that the partner is welcome to attend. Partners are now included in the consultation.

Pain clinic attenders: an audit.

An audit of the first 135 referrals to a new Multidisciplinary Pain Clinic was conducted. Demographic data, pain experience and pain effects were recorded. Chronic Non-Malignant Pain was the diagnosis found most frequently. In that group, the mean duration of pain was seven years, the mean number of surgical operations was 1.95 and the mean number of medications being consumed at the time of presentation 3.5. Impaired occupational, social and recreational functioning was noted. Twice as many women were affected as men and all educational and socio-economic groups were represented. Patient profiles were similar to data published on chronic pain patients attending the Mayo Clinic, Minnesota, USA.

The effects of hospital admission on drug prescribing in an elderly population.

307 consecutive patients admitted to our unit were studied. The reasons for altering patients' drug regimens were noted. The price difference between the patients' drugs on admission to those on discharge was calculated. While over 40% of drugs regimens on admission were unchanged on discharge some adjustments were made in the remainder. The most common reason for stopping a drug was that the hospital physician could find no indication for its use. A 30.3% reduction in price of discharge drugs compared with drugs on admission was achieved.
