Rationale:
Double cortex syndrome is a malformation in which there is a band of subcortical heterotopic grey matter separated from the cortex by white matter. The functional activity of the heterotopic neurons is unclear.
Patient:A 13-year-old female was evaluated for seizures. The EEG showed bifrontal spike wave disturbance. Band heterotopia, in association with mild reduction of sulcation of the cerebral hemispheres, was found on MRI. Psychological assessment indicated the presence of variable cognitive abilities, with verbal IQ [82] generally better than nonverbal IQ [59], and specific difficulties in language comprehension and mathematics.
Method:Functional MRI was used to localize the areas of language and motor activation. The language activation paradigm was a visual verb generation task with a visual fixation baseline. The motor paradigm consisted of alternating blocks of sequential finger tapping and rest. Coronal functional and anatomical images were obtained.
Results:The motor paradigm produced activation of the primary motor cortex, the band heterotopia and the supplementary motor cortex. The language paradigm produced activation of the left inferior frontal gyrus and left supplementary motor area, but not of the band heterotopia.
Conclusions:The activation of heterotopic grey matter during a motor task demonstrates a hemodynamic association with motor activity and suggests that this tissue may be functional. Such association was not seen with the language task. We speculate that later maturing functions such as language are restricted in their development to the normal situated superficial cortex in our patient.

The occurrence of episodes of getting lost was examined in 104 subjects with dementia who were assessed every 4 months over 5 years. All subjects were initially living at home with a caregiver who could give good information. Forty-three subjects needed to be brought back home at least once. Five subjects repeatedly got lost. Forty-six subjects were kept behind locked doors at some point. Subjects who got lost were more likely to become permanently resident in institutions (odds ratio = 7.3; 95% confidence interval: 3.0 to 17.8). Patients who performed better on a behavioral test of topographical memory were less likely to get lost over the subsequent 5 years (negative predictive value: 90%). The risk of patients with dementia getting lost is substantial and requires frequent intervention by caregivers. This risk is a major reason for institutionalization. A simple test may help in assessing the risk of getting lost in patients with dementia.

Objective: This article analyzes the natural history of wandering behavior throughout the course of dementia. Design: Prospective, 10-year, longitudinal study of wandering behavior in dementia, with autopsy follow-up. Setting: Participants with dementia, living at home with a carer. All lived in Oxfordshire, UK. Participants: Eighty-six people with dementia who were living at home with a carer and who were able to walk unaided at entry to study. Measures: At 4-monthly intervals, the carers were interviewed using the Present Behavioural Examination to assess wandering behavior were distinguished. Results: Changes in wandering behavior were not generally related to gender, age, or time since onset of dementia. Onset of different types of wandering behavior showed some relationship with cognitive state. Various forms of increased walking first appeared during moderate dementia, each type typically persisting for 1 to 2 years. Late dementia was characterized by decreased walking and immobility. Conclusions: Wandering behavior in dementia can cause great problems for carers. There are different causes for such changes, some of which are related to cognitive ability, for example increased confusion results in ineffectual “pottering” and getting lost. Increased walking at night corresponds with disruption of diurnal rhythm.

Background:
Defining risk factors for central venous catheter (CVC)-associated bloodstream infections (BSIs) is critical to establishing prevention measures, especially for factors such as nurse staffing and antimicrobial-impregnated CVCs.
Methods:We prospectively monitored CVCs, nurse staffing, and patient-related variables for CVC-associated BSIs among adults admitted to eight ICUs during 2 years.
Results:A total of 240 CVC-associated BSIs (2.8%) were identified among 4,535 patients, representing 8,593 CVCs. Antimicrobial-impregnated CVCs reduced the risk for CVC-associated BSI only among patients whose CVC was used to administer total parenteral nutrition (TPN, 2.6 CVC-associated BSIs per 1,000 CVC-days vs no TPN, 7.5 CVC-associated BSIs per 1,000 CVC-days; P = .006). Among patients not receiving TPN, there was an increase in the risk of CVC-associated BSI in patients cared for by “float” nurses for more than 60% of the duration of the CVC. In multivariable analysis, risk factors for CVC-associated BSIs were the use of TPN in non-antimicrobial-impregnated CVCs (P = .0001), patient cared for by a float nurse for more than 60% of CVC-days (P = .0019), no antibiotics administered to the patient within 48 hours of insertion (P = .0001), and patient unarousable for 70% or more of the duration of the CVC (P = .0001). Peripherally inserted central catheters (PICCs) were associated with a lower risk for CVC-associated BSI (P = .0001).
Conclusions:Antimicrobial-impregnated CVCs reduced the risk of CVC-associated BSI by 66% in patients receiving TPN. Limiting the use of float nurses for ICU patients with CVCs and the use of PICCs may also reduce the risk of CVC-associated BSI.

Background
Previous studies have shown a positive relationship between disease severity and cost.
AimsTo explore the factors affecting time to institutionalisation and estimate the relationship between the costs of care and disease progression.
MethodRetrospective analysis of a longitudinal data-set for a cohort of 100 patients diagnosed with Alzheimer's disease or vascular dementia.
ResultsChanges in both Mini-Mental State Examination (MMSE) and Barthel scores have independent and significant marginal effects on costs. Each one-point decline in the MMSE score is associated with a £56 increase in the four-monthly costs, whereas each one-point fall in the Barthel index is associated with a £586 increase in costs.
ConclusionsIt may be inappropriate for economic models of disease progression in dementia to be based solely on measures of cognitive change. MMSE and the Barthel index are independent significant predictors of time to institutionalisation and cost of care, but changes in the Barthel index are particularly important in predicting costs outside institutional care.

Background
Alzheimer's disease and other types of dementia are characterised by numerous psychiatric and behavioural changes. Little is known of their natural history.
AimsTo investigate the sequence and pattern of these changes throughout the course of dementia.
MethodOne hundred people, initially living at home with carers, entered a prospective, longitudinal study. At four-monthly intervals, behavioural and psychiatric symptoms were assessed using the Present Behavioural Examination and Mini-Mental State Examination. Follow-up continued for up to nine years (mean 3.3 years; s.d. 2.4). Patterns of onset and disappearance of these symptoms, their sequence and association with time of death and cognitive decline were analysed. Autopsy confirmed a diagnosis of pure Alzheimer's disease in 48 subjects. Data for this subgroup are presented.
ResultsSome changes tend to occur earlier than others but changes can occur at almost any time in the course of dementia.
ConclusionsThe natural history of behaviour changes in Alzheimer's disease shows great individual variation although some changes tend to follow a recognisable sequence.
