Children with autism have specific difficulties understanding complex mental states like thought, belief, and false belief and their effects on behaviour. Such children benefit from focused teaching, where beliefs are likened to photographs-in-the-head. Here two studies, one with seven participants and one with 10, tested a picturein-the-head strategy for dealing with thoughts and behaviour by teaching children with autism about cartoon thought-bubbles as a device for representing such mental states. This prosthetic device led children with autism to pass not only false belief tests, but also related theory of mind tests. These results confirm earlier findings of the efficacy of picture-in-the-head teaching about mental states, but go further in showing that thought-bubble training more easily extends to children's understanding of thoughts (not just behaviour) and to enhanced performance on several transfer tasks. Thought-bubbles provide a theoretically interesting as well as an especially easy and effective teaching technique.

Objective A homeostatic imbalance between coagulation and fibrinolysis might occur intrathecally in neuropsychiatric systemic lupus erythematosus (NPSLE). However, there are no published data on levels of fibrinolytic factors in the cerebrospinal fluid (CSF) of patients with NPSLE. The present study was undertaken to assess CSF levels of fibrinolytic molecules, including urokinase plasminogen activator (uPA), tissue plasminogen activator (tPA), D‐dimer, and plasminogen activator inhibitor 1 (PAI‐1), in SLE patients with clinically verified neuropsychiatric involvement and to compare these levels with those in SLE patients without neuropsychiatric involvement and in healthy subjects. Methods Levels of uPA, tPA, and PAI‐1 were assessed in CSF from 94 patients with SLE (33 who had NPSLE, 56 who did not have NPSLE, and 5 who were positive for antiphospholipid antibody [not included in the NPSLE or non‐NPSLE group]) and from 53 age‐matched controls. Patients were evaluated clinically, with magnetic resonance imaging of the brain, analyses of neuronal/glial degradation products in CSF, and neuropsychiatric testing. Results In the group of patients with NPSLE, intrathecal PAI‐1 levels were significantly elevated compared with levels in SLE patients without overt neuropsychiatric involvement (P < 0.05) and in healthy controls (P < 0.001). In contrast, intrathecal levels of uPA did not differ significantly. Intrathecal levels of PAI‐1 correlated significantly with CSF levels of interleukin‐6 (IL‐6) (r = 0.34, P < 0.001) and IL‐8 (r = 0.33, P < 0.001). Importantly, increased PAI‐1 and D‐dimer levels were observed in SLE patients who had pathologically elevated levels of glial fibrillary acidic protein, neurofilament triplet protein, and tau protein in CSF. Conclusion Intrathecal release of PAI‐1 is increased in patients with NPSLE. This results in impaired fibrinolysis, which might contribute to neuronal and astrocytic damage in NPSLE.

This study examines a low-income, urban elderly population of dental and medical, nondental users. A total of 1,378 medical, nondental users and 2,086 dental users were identified using longitudinal claims data (1983-1992) from a Medicare-waiver program that reimbursed for health care services at cost. Dental users were more likely to be from a younger age cohort (born after 1910, p = .0001) and were more likely to be black (63.3% vs 35.7%, P = .0001) than medical, nondental users. Medical, nondental users had more medical visits (p = .0001), higher medical and pharmacy charges (p = .0001), and more prescriptions (p = .0001) than did the dental users. These findings indicate that among this population of urban elderly, dental users were more likely to be black and have lower medical utilization than nondental users.

Prescription insurance coverage and sleep disturbances are important considerations underlying patient preferences for the treatment of overactive bladder.

Effects of case management on quality of life were tested with 57 home care patients with AIDS, randomly assigning individuals to either usual care or case-managed care over the duration of home services (ranging from 5 days to over 2 years). Participants were primarily male (93%), white (79%), and never married (82%). Quality of life was measured monthly using the quality of Well-Being Index (QWB). Case-managed patients showed advantages over the usual care group in descriptive analyses of quality of life and survival. Large standard deviations in the QWB scores resulting from high fatality among subjects impeded statistical analyses of effects.
