Quality of life and standard of living in a randomly selected group of psychiatrically disabled people in Sweden 2 years after a psychiatry reform.

In Sweden, a psychiatry reform, aimed at improving the living conditions of the psychiatrically disabled, came into force in 1995. The aim of the present study was to evaluate the impact of the reform by investigating quality of life and standard of living 2 years later in a randomly selected group of people with longstanding psychiatric disability. Self-ratings and interviews were conducted in a study group and a control group. The study group consisted of 19 women and 18 men (mean age 46.1 years) diagnosed with neurosis, schizophrenia or affective disorder. The control group consisted of 19 women and 17 men (mean age 48.7 years). Self-rated quality of life was significantly poorer in the study group (P < 0.0001, unpaired t-test), and so was housing (P < 0.001, test of similar proportions in independent samples). We found no significant positive correlation between subjective quality of life and standard of living in either group but a significant negative correlation in the control group (P < 0.05; r = 0.40, Pearson correlation coefficient). The results suggest that, in 1997, people with longstanding psychiatric disability still had poorer quality of life than the general population. This may be due to factors other than outward standard of living.     

Preliminary evaluation of vitiligo using in vivo reflectance confocal microscopy

BACKGROUND: Vitiligo is the most common pigmentary disorder with a global incidence from 0.1% to 2% in different geographical areas. Histopathology and histochemistry have shown the reduction of melanocytes in achromic patches, but microscopic changes of lesional and non-lesional skin are still not completely understood. Reflectance confocal microscopy (RCM), based on the different light reflectance index of cutaneous structures, allowed in vivo, en face microscopic evaluation of superficial skin layers with a resolution similar to skin histology. AIM: The purpose of this study was to evaluate RCM features of lesional and non-lesional skin of vitiligo patients. Moreover, re-pigmented areas were taken into consideration in order to evaluate melanocyte response to ultraviolet B (UVB) radiation. SUBJECTS AND METHODS: Sixteen patients of different phototypes affected by active non-segmental vitiligo and 10 controls were enrolled in the study. In vivo skin imaging was done using a commercially available RCM (Lucid, Vivascope 1500. Re-pigmented areas from 6 to 16 patients (after UVB narrow-band therapy) were also examined. RESULTS: Vitiligo lesions showed the disappearance of the bright rings normally seen at the dermo-epidermal junction. Moreover, non-lesional skin of vitiligo patients showed unexpected changes as the presence of half-rings or scalloped border-like features of the bright papillary rings. In re-pigmented areas after UVB narrow band therapy, the presence of activated, dendritic melanocytes was seen. CONCLUSIONS: Considering our results, and following further studies, RCM clinical applications could be used in the therapeutic monitoring and evaluation of the evolution of vitiligo.     

Nicotine fading, behavioral contracting, and extended treatment: effects on smoking cessation

Twenty-eight subjects were randomly allocated to either a nicotine fading or a maintenance condition. The maintenance condition utilized behavioral contracting and extended treatment in addition to the nicotine fading to improve treatment outcome and avoid relapse. The maintenance condition achieved superior outcome on smoking measures at post-treatment and follow-up periods for self-reported smoking levels. Carbon monoxide levels were significantly lower for the maintenance condition at post-treatment, three month and six month follow-up. Saliva thiocyanate levels were significantly lower for the maintenance condition at the three month follow-up. Changes in health functioning indicated significantly lower diastolic and systolic blood pressure at six month follow-up for the maintenance condition. Additional research on nicotine regulation during nicotine fading and thiocyanate levels during experimental smoking would be useful. The use of behavioral contracting to enhance maintenance without therapeutic support warrants further research as well.     

In situ saphenous vein bypass grafts: angiographic evaluation and interventional repair of complications

In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications.     

Hemorrhagic and nonhemorrhagic brain lesions: evaluation with 0.35-T fast MR imaging

Two fast magnetic resonance (MR) imaging techniques, advanced Fourier and partial-flip imaging, were used at 0.35 T to examine 21 patients with suspected intracranial lesions; the results were quantitatively compared with a conventional spin-echo study. Both of the fast MR techniques yielded a fourfold reduction in imaging time per section. The advanced Fourier sequence showed contrast that was identical to the conventional spin-echo study with signal-to-noise ratios of 58% and 57% for the first and second echoes, respectively. The partial-flip sequence showed a contrast of 109% and 57% for lesions versus substantia alba, and 107% and 78% for substantia grisea versus substantia alba relative to the first and second echoes of the conventional spin-echo study. The partial-flip sequence was particularly sensitive to magnetic susceptibility; this produced artifacts that may undermine the usefulness of partial flip for routine screening in certain parts of the brain. However, this susceptibility significantly improved the detection of intracranial hemorrhage when compared with the spin-echo sequence, particularly when combined with phase mapping of the partial-flip study.
