Folie à deux: double case-report of shared delusions with a fatal outcome.

BACKGROUND: Treatment of shared delusional disorder (folie à deux) often involves separation and use of antipsychotic medication, with uncertain outcomes and potential risks. METHODS: We report on two highly interdependent and chronically psychotic sisters with shared systematic delusion, followed by psychiatrists over several years. RESULTS: The dominant patient was diagnosed with schizoaffective disorder and her non-dominant sister with paranoid schizophrenia. Both received antipsychotics and supportive therapy as outpatients and allowed to continue conjoint therapy with individual psychiatrists-therapists. They returned for follow-up visits for 20 months, when the dominant decided to continue treatment alone, as her sister gradually improved symptomatically and functionally. After separation, the dominant became increasingly anxious. She impulsively ingested an overdose of the non-dominant sister's medicines and died of cardiac arrest, despite her sister's efforts to seek medical assistance. The surviving non-dominant sister developed anxiety and increasing agitation requiring psychiatric hospitalization and increased pharmacotherapy. She improved gradually, but continued to be dysfunctional and required placement in a psychiatric inpatient unit for several months, eventually doing better in a community-based rehabilitative program with regular psychiatric follow-up. CONCLUSIONS: Combined treatment of patients with folie à deux may encourage continuous pathological interactions, but separation may increase risk of adverse outcomes.

Nine years' experience of telecardiology in primary care.

The ITMS telecardiology network started in April 1995. Over nine years, about 7000 peripheral medical users (mainly general practitioners), who were experienced in using transtelephonic electrocardiography and who were spread throughout Italy, conducted teleconsultations with the Telecardiology Centre. A total of 106,942 patients were evaluated. Teleconsultation was carried out for non-cardiac symptoms or routine control for 30,444 patients (28%) and for symptoms suggestive of heart disease for 76,498 (72%). After teleconsultation, 61,908 patients (58%) were reported to have no heart disease, 27,947 patients (26%) had their drug dose adjusted and remained at home, 11,503 patients (11%) were sent to their cardiologist for further investigations and 5584 patients (5%) were urgently hospitalized. Among the hospitalized patients, the echocardiogram demonstrated an ST-elevation coronary syndrome in 1785 patients (32%), a non-ST-elevation coronary syndrome in 2236 (40%) and a life-threatening arrhythmia in 1354 (24%). Telecardiology improves the decision making of general practitioners, avoids unnecessary hospitalizations, reduces the time before treatment in cardiac emergencies, rationalizes health-care costs and promotes home care.

Blunted catecholamine responses after glucose ingestion in children with attention deficit disorder.

Eating simple sugars has been suggested as having adverse behavioral and cognitive effects in children with attention deficit disorder (ADD), but a physiologic mechanism has not been established. To address this issue, metabolic, hormonal, and cognitive responses to a standard oral glucose load (1.75 g/kg) were compared in 17 children with ADD and 11 control children. Baseline and oral glucose-stimulated plasma glucose and insulin levels were similar in both groups, including the nadir glucose level 3-5 h after oral glucose (3.5 +/- 0.2 mmol/L in ADD and 3.3 +/- 0.2 mmol/L in control children). The late glucose fall stimulated a rise in plasma epinephrine that was nearly 50% lower in ADD than in control children (1212 +/- 202 pmol/L versus 2228 +/- 436 pmol/L, p < 0.02). Plasma norepinephrine levels were also lower in ADD than in control children, whereas growth hormone and glucagon concentrations did not differ between the groups. Matching test scores were lower and reaction times faster in ADD than in control children before and after oral glucose, and both groups showed a deterioration on the continuous performance test in association with the late fall in glucose and rise in epinephrine. These data suggest that children with ADD have a general impairment of sympathetic activation involving adrenomedullary as well as well as central catecholamine regulation.
