Distinct neuropsychological profiles correspond to distribution of cortical thinning in inherited prion disease caused by insertional mutation
2012
Background The human prion diseases are a group of universally fatal neurodegenerative disorders associated with the auto-catalytic misfolding of the normal cell surface prion protein (PrP). Mutations causative of inherited human prion disease (IPD) include an insertion of six additional octapeptide repeats (6-OPRI) and a missense mutation (P102L) with large families segregating for each mutation residing in southern England. Here we report for the first time the neuropsychological and clinical assessments in these two groups. Method The cognitive profiles addressing all major domains were obtained for 26 patients (18 6-OPRI, 8 P102L) and the cortical thickness determined using 1.5T MRI in …
Basilar Artery Diameter Is a Potential Screening Tool for Fabry Disease in Young Stroke Patients
2010
<i>Background:</i> Fabry disease (FD) is a rare hereditary lysosomal storage disease that has been highlighted as a possible etiology of stroke at a young age. Enlarged basilar artery diameters (BADs) have been demonstrated in FD, and we hypothesize that they might be useful for the screening of FD in young stroke patients. The aim of this study was to compare BADs of young stroke patients without FD to those of FD patients and of healthy age-matched controls. <i>Methods:</i> BADs were measured using MR angiography in 3 age- and gender-matched groups: 25 FD patients (aged 36.5 ± 11.0 years), 26 non-FD stroke patients and 20 healthy controls. <i>Results:</i&g…
Evaluation of prognostic factors and their capacity to predict biological behavior in gastrointestinal stromal tumors.
2011
Gastrointestinal stromal tumors (GISTs) are c-KIT-signaling-driven mesenchymal tumors of the human digestive tract, many of which have c-KIT or PDGFRα activating mutations. The authors studied the immunohistochemical markers, c-KIT and PDGFRα mutations, in GISTs and their association with the clinicopathological and clinical follow-up in 145 GISTs. Tumors were located mainly in the stomach, the median tumor size being 7.5 cm. The mitotic index was ≤5 mitoses per 50 high-power fields in 61% of cases, 96% expressed CD117, and c-KIT or PDGFRα mutations were detected in 68% of cases. The median follow-up of the series was 52 months (range = 1 to 244.9 months). Tumor size, cell morphology, mito…
Prenatal manganese exposure and neuropsychological development in early childhood in the INMA cohort.
2020
Abstract Introduction Manganese (Mn) is an essential element, diet being its main source. Some epidemiological studies have found that a prenatal excess of Mn could negatively affect neuropsychological development during infancy, but the evidence is inconclusive. The aim of this study was to explore the relationship between maternal serum Mn concentrations and child neuropsychological development assessed at 1 year of age. Methods study subjects were 1179 mother–child pairs from two Spanish cohorts (Valencia and Gipuzkoa) of the INMA (Environment and Childhood) Project. Mn was measured in serum samples collected during the first trimester of pregnancy. Child neuropsychological development w…
Single dose vaccination with AS03-adjuvanted H5N1 vaccines in a randomized trial induces strong and broad immune responsiveness to booster vaccinatio…
2009
Priming a population with a pre-pandemic vaccine is being considered to maximize the response upon subsequent vaccination with a true pandemic vaccine more closely matched to the causative pandemic strain. The present study explored this prime-boost concept by evaluating different primary schedules with the pre-pandemic A/Vietnam/1194/2004(NIBRG-14) vaccine, containing 3.75 microg of HA, followed by a 6-month booster with a vaccine formulated with 3.75 microg HA of either the same strain or with A/Indonesia/05/2005(IBCDC-RG2), a heterologous strain from a different clade. In this multicentre, open, randomized study (NCT00430521) we measured immune responses in four groups (N = 48-60) of adu…
Circulating 25-Hydroxyvitamin D3 in Pregnancy and Infant Neuropsychological Development
2012
OBJECTIVE:To investigate whether circulating 25-hydroxyvitamin D3 [25(OH)D3] concentration in pregnancy is associated with neuropsychological development in infants.METHODS:The Spanish population-based cohort study INfancia y Medio Ambiente Project recruited pregnant women during the first trimester of pregnancy between November 2003 and February 2008. Completed data on 1820 mother-infant pairs were used. Maternal plasma 25(OH)D3 concentration was measured by high-performance liquid chromatography in pregnancy (mean 13.5±2.1 weeks of gestation). Offspring mental and psychomotor scores were assessed by trained psychologists at age 14 months (range, 11–23) by using the Bayley Scales of Infant…
Long-term management and prognosis of autoimmune hepatitis (AIH): a single center experience.
2001
Background Controlled trials have firmly established the need for immunosuppressive therapy in autoimmune hepatitis. However, reports about long-term management and prognosis of the disease are scarce. Patients and methods We reviewed the charts of 103 consecutive patients with a well-documented long-term course of autoimmune hepatitis who had been carefully managed over a mean observation period of 95 months (12-405 months). Results Under immunosuppressive therapy 94 patients (91.2%) reached complete remission after a mean treatment duration of 3 +/- 3 months. 28 of the 103 patients (27.2%) were eligible for a trial of treatment withdrawal after a mean treatment duration of 32.2 months (ra…
Mean temperature and humidity variations, along with patient age, predict the number of visits for renal colic in a large urban Emergency Department:…
2012
Background: A marked geographic variability has been reported in stone disease, partially attributed to the Mean Annual Temperature (MAT), as well as to the seasonal fluctuations of climatic conditions. Accordingly, peaks in Emergency Department (ED) visits for renal colic are commonplace during the summer. Materials and methods: The aim of this study was to assess the influence of day-by-day climate changes on the number of visits as a result of renal colic in the ED (City of Parma, northern Italy, temperate continental climate). A total of 10,802 colic episodes were retrieved from the database during a period of 3286 days (January 2002 to December 2010). Results: The analysis of the data …
Iodine intake from supplements and diet during pregnancy and child cognitive and motor development: the INMA Mother and Child Cohort Study
2017
BackgroundThe effect of mild-to-moderate maternal iodine deficiency on the neuropsychological development of their offspring is uncertain. We aimed to assess the association between iodine status during pregnancy and the cognitive and motor development of children at 4–5 years.MethodsWe conducted a prospective cohort study in four Spanish regions with recruitment of pregnant women between 2003 and 2008 and follow-up of their children up to 4–5 years (mean (SD)=4.8 (0.6)). Cognitive and motor function was assessed in 1803 children using the McCarthy Scales of Children’s Abilities. Dietary iodine and supplementation were measured through questionnaires twice during pregnancy. Urinary iodine c…
Age of onset of episodic and chronic cluster headache – a review of a large case series from a single headache centre
2016
Background In the largest case series of cluster headache (CH) published in the literature, age of onset varies between 29.6 and 31.6 years. Differences in onset age based on gender and subtype diagnosis are reported, while there are only few data on patients with childhood and elderly onset. We therefore deemed it useful to review our own large case series of CH patients. Methods The age of onset of cluster headache was investigated in a consecutive case series of 808 patients (585 men and 223 women), including 686 (503 men and 183 women) with episodic cluster headache (ECH), 103 (66 men and 37 women) with chronic cluster headache (CCH), and 19 with an indeterminate form of CH (16 men and …
