Symptom profile of DSM-IV major and minor depressive disorders in first-ever stroke patients.

OBJECTIVE: Depressive disorders are very common in stroke patients. However, vegetative and cognitive symptoms primarily derived from brain damage could hypothetically be indistinguishable from those directly derived from neuropsychiatric disorders, and this could invalidate the diagnostic assessment. Thus, authors aimed to detect the frequency of clinically-rated DSM-IV depressive symptoms and the diagnostic validity of depressive disorders in stroke patients suffering from major depressive disorder (MDD), minor depressive disorder (MIND), and those free of any neuropsychiatric disorders (NODEP). METHODS: First-ever stroke patients (N=200) were approached within 3 months of the acute stroke and were interviewed with the SCID-P and administered the Hamilton Rating Scale for Depression (Ham-D), the Beck Depression Inventory (BDI), the Barthel Index, and the Mini-Mental State Exam. RESULTS: Fifty patients (25%) had MDD, 62 (31%) had MIND, and 88 (44%) had NODEP. Global cognitive level, functional impairment, total scores, and psychic and somatic subscores of the Ham-D and the BDI were different among the three groups. The only symptom that did not differ among patients with MDD, MIND, and NODEP was Feelings of Guilt; all the other eight DSM-IV symptoms were significantly different. In particular, the frequency of Depressed Mood, Diminished Interest or Pleasure, Fatigue or Loss of Energy, Insomnia, and Psychomotor Agitation/Retardation was higher in MIND patients than in NODEP patients. CONCLUSIONS: During the diagnostic procedure for depressive disorders in stroke patients, clinicians should consider equally important vegetative, cognitive, and psychological depressive symptoms, despite their nature.     

Stopping a medical research project for financial reasons

Sir, We are writing to provide some clarifications on the EditorialComment by Drüeke et al. [1]. We would have been happyto provide these very same clarifications had we been fairlyinvited to do so before the publication of the article. First of all, we would like to     

Sources of cortical rhythms change as a function of cognitive impairment in pathological aging: a multicenter study.

OBJECTIVE: The present study tested the hypothesis that cortical electroencephalographic (EEG) rhythms. change across normal elderly (Nold), mild cognitive impairment (MCI), and Alzheimer's disease (AD) subjects as a function of the global cognitive level. METHODS: Resting eyes-closed EEG data were recorded in 155 MCI, 193 mild AD, and 126 age-matched Nold subjects. EEG rhythms of interest were delta (2-4 Hz), theta (4-8 Hz), alpha 1 (8-10.5 Hz), alpha 2 (10.5-13 Hz), beta 1 (13-20 Hz), and beta 2 (20-30 Hz). EEG cortical sources were estimated by LORETA. RESULTS: Occipital delta and alpha 1 sources in parietal, occipital, temporal, and 'limbic' areas had an intermediate magnitude in MCI subjects compared to mild AD and Nold subjects. These five EEG sources presented both linear and nonlinear (linear, exponential, logarithmic, and power) correlations with the global cognitive level (as revealed by mini mental state examination score) across all subjects. CONCLUSIONS: Cortical EEG rhythms change in pathological aging as a function of the global cognitive level. SIGNIFICANCE: The present functional data on large populations support the 'transitional hypothesis' of a shadow zone across normality, pre-clinical stage of dementia (MCI), and AD.     

Implementing a parent involvement/parent education program in a children's residential treatment center

Two prominent trends in contemporary child welfare, permanency planning and the family-centered model of care, are old theoretical ideas that have had great difficulty in finding corresponding practice methodologies. This article presents a practical model and discussion of the strategy and tactics involved in the process of developing and implementing a family-centered model by providing an effective parent involvement program in the residential treatment setting. Both didactic and experiential components are suggested, with emphasis on the latter in the context of planned change and the needs of children, parents, staff, and agency administration.     

gamma-ray spectrometry of soil samples from the Provincia dell'Aquila (Central Italy).

In the Abruzzo Region (Central Italy) there is a lack of measurements of gamma-ray activity in soils and waters. For this reason, we have planned to carry out a systematic measurement of soils in the area of the Provincia dell'Aquila, which covers about one-half of the entire region. In this paper we report the results obtained from 56 soil samples, collected in the northern part of the area of interest (about one-fourth of the total area under study). The results, in terms of content of uranium, thorium and potassium and the activity of caesium are reported, as well as the details on the experimental procedure. The results show a limited content of K and U, with no large variations from site to site, in agreement with the expectations based on the knowledge of the geo-lithological nature of the soil. The amount of Th is also quite limited, with a few exceptions where the Th content is up to five times the average value. Caesium, originated from the fall-out following the Chernobyl accident, is very irregularly distributed owing to the complicated orography of the land. Future plans are also shortly discussed.     

Clinical classification of bone defects concerning the placement of dental implants

The goal of this classification of bone defects related to dental implant placement is to help clinicians accurately discuss proposed treatment regimens and organize treatment for clinical correction. A further goal of this effort to categorize bone defects requiring bone augmentation for implant placement is to standardize terminology to allow for more accurate dental communication. The 5 most encountered categories of bony defects are described.     

Inhibitory action of quercetin on intestinal transit in mice

The effects of quercetin have been investigated on the gastrointestinal propulsion of charcoal meal in mice. Quercetin reduced the rate of intestinal transit and this effect was potentiated by verapamil.
