APOE-related frequency of cognitive and noncognitive symptoms in dementia.

Although memory disorders and the aphaso-apraxo-agnosic syndrome are the most relevant clinical symptoms in dementia, behavioral changes, mood-related disturbances and sleep disorders are the major cause of institutionalization and caregiver concern. In the present study we have investigated the frequency and progression of cognitive and noncognitive symptoms in Alzheimer's disease (AD) as well as the APOE-related frequency of clinical symptoms in dementia. Memory decline (100%), aphasia (94%), apraxia (99%), agnosia (94%) and motor dysfunction (90%) appeared in practically all cases with mild (GDS-3), moderate (GDS 3-4) and severe (GDS 6-7) dementia. The most frequent noncognitive symptoms include anxiety (76%), depression (68%), behavioral changes (67%), psychotic symptoms (43%), sleep disorders (43%), incontinence (23%) and cerebrovascular symptoms (75%). Anxiety, depression, behavioral changes, psychotic symptoms, motor dysfunction and cognitive deterioration paralleled the severity of dementia, increasing their frequency from mild to severe dementia. The most important sleep disorders were irregular sleep-wake pattern (67%) and insomnia (47%). Disorientation (90%) and drug administration (88%) appeared to be the most important factors in causing sleep disorders in dementia. Disorientation, agitation and motor disorders were slightly more frequent in patients with APOE-4/4, while anxiety and sleep disorders appeared more frequently in APOE-3/4. Behavioral changes and psychotic symptoms did not show any clear association with specific APOE subtypes. In conclusion, our results suggest that noncognitive symptoms are very important clinical events in the disease progression and in decision making for therapeutic intervention and institutionalization. Furthermore, it is likely that some brain dysfunctions leading to particular clinical symptoms might be associated with specific AD genotypes.

Ductal carcinoma in situ (DCIS) of the breast: the need for psychosocial research.

Since the introduction of the National Health Service Breast Screening Programme (NHSBSP), the number of ductal carcinoma in situ (DCIS) cases has increased considerably. Despite its increased incidence, some NHS leaflets and reports do not mention it, and the general public seems largely unaware of its existence. There are numerous biological studies dealing with this condition, but its psychosocial aspects seem to have been neglected. We have only been able to locate two British studies (Farmer, A. 1996. Unpublished PhD thesis, University of Southampton; Webb, C. and Koch, T. 1997. J. Adv. Nurs., 25, 154-525) that address some of the psychosocial issues associated with DCIS. This paper starts by defining DCIS and explaining its usual presentation, natural history and epidemiology. The treatment options for DCIS are described, together with the great deal of confusion and lack of agreement that accompanies them. The psychological issues that women with screen-detected DCIS have to deal with are different from those affecting women diagnosed with symptomatic breast cancer, and a summary of these issues is given. Finally, some suggestions for future psychosocial research are provided. Because the UK as a whole was not covered by the NHSBSP until 1990 (Baum, M. 1995. Lancet, 346, 436; Gage and Fouquet, 1997), the main focus will be on papers published from that year onwards, although some key papers published before then will also be included. The papers reviewed here were found in MEDLINE, EMBASE and BIDS (ISI).

Tungiasis in a 3-year-old child.

Tungiasis is an infestation of the skin caused by the flea Tunga penetrans. It is not rare in western Europe because of tourism to tropical and subtropical countries. However, tungiasis has been very rarely reported in children. We describe a case of tungiasis in a 3-year-old child. The infestation was localized to the second toe of the left foot and was characterized by an atypical clinical presentation.
