Verbal suppression and strategy use: a role for the right lateral prefrontal cortex?

2015

Verbal initiation, suppression and strategy generation/use are cognitive processes widely held to be supported by the frontal cortex. The Hayling Test was designed to tap these cognitive processes within the same sentence completion task. There are few studies specifically investigating the neural correlates of the Hayling Test but it has been primarily used to detect frontal lobe damage. This study investigates the components of the Hayling Test in a large sample of patients with unselected focal frontal (n = 60) and posterior (n = 30) lesions. Patients and controls (n = 40) matched for education, age and sex were administered the Hayling Test as well as background cognitive tests. The sta…

Sensitivity to heat in MS patients: a factor strongly influencing symptomology -- an explorative survey

2011

Published version of an article to be found in BMC Neurology 2011, 11:27, http://dx.doi.org/10.1186/1471-2377-11-27 Background: Many individuals diagnosed with Multiple Sclerosis (MS) are sensitive to increased body temperature, which has been recognized as correlating with the symptom of fatigue. The need to explore this association has been highlighted. The aim of this study was to investigate the occurrence of heat sensitivity and its relations to disease course, disability, common MS-related symptoms and ongoing immunosuppressive treatments among individuals 65 years of age or younger diagnosed with MS. Methods: A cross-sectional designed survey was undertaken. A questionnaire was sent …

Mean 14.00-17.00 h plasma cortisol concentration and its relationship to the 1 mg-dexamethasone suppression response in depressives and controls.

1984

Three-hour cortisol-profiles and cortisol responses to a 1 mg dose of dexamethasone were recorded in 31 depressed patients and nine controls. The data indicate that the likelihood of detecting non-suppressible cortisol concentrations after dexamethasone is significantly increased in depressed patients with a hypersecretion of cortisol. However, a considerable subsample of normosecretors shows abnormal DST results. Conversely, hypersecretion is often associated with dexamethasone suppression. In this study a 1 mg-DST did not reflect the adrenocortical activity with ultimate accuracy. Therefore any attempts which correlate psychopathological or biological data with pituitary-adrenal activity …

Computerized brain tomography measures compared with spontaneous and suppressed plasma cortisol levels in major depression.

1989

We determined brain density and ventricular measurements with computerized tomography (CT) in 33 depressed patients and compared the results with basal plasma cortisol and its suppressibility by dexamethasone. Mean plasma cortisol was positively related to elevated ventricular brain ratio (VBR). No association could be found between dexamethasone suppression test (DST) status and VBR or any other CT parameter. Elevated plasma cortisol levels and increased VBRs were positively correlated with total scores on the Brief Psychiatric Rating Scale, the Global Assessment Scale and the Bech-Rafaelsen Melancholia Scale, but they were not significantly correlated with total score on the Hamilton Anxi…

Multisteroid analysis after DST in depressed patients — A controlled study

1986

Abstract 111 consecutively admitted in-patients with a depressive syndrome received a dexamethasone suppresion test (DST) after all known factors which might confound the test results had been carefully excluded. Plasma concentrations of cortisol, corticosterone and dexamethasone were compared with several diagnostic evaluations (RDC, DSM-III, ICD-9) in a controlled study. The positive predictive value of nonsuppressed corticosteroid levels was only moderate for each diagnostic category. Diagnostic specificities were 84.6% for major depression, endogenous subtype (RDC), 71.2% for melancholia (DSM-III) and 86.8% for endogenous depression (IDC-9) when using a post-DST cortisol value above 50 …

Increased Risk of Acute Myeloid Leukemias and Myelodysplastic Syndromes in Patients Who Received Thiopurine Treatment for Inflammatory Bowel Disease.

2014

Background & Aims Treatment with immunosuppressive thiopurines such as azathioprine is associated with an increased risk of leukemogenesis. We assessed the risk of myeloid disorders, such as acute myeloid leukemia and myelodysplastic syndromes, in a large cohort of patients with inflammatory bowel disease (IBD) in France. Methods We performed a prospective observational study of 19,486 patients with IBD enrolled in the Cancers Et Surrisque Associe aux Maladies inflammatoires intestinales En France (CESAME) study from May 2004 through June 2005; patients were followed through December 31, 2007. The incidence of myeloid disorders in the general population, which was used for reference, was de…

Tolerability profile of thiopurines in inflammatory bowel disease: a prospective experience

2017

The occurrence of thiopurine-related adverse events (AEs) may complicate the management of patients with inflammatory bowel disease (IBD). We aimed to evaluate the tolerability of thiopurines in a current IBD setting.All consecutive patients who started a treatment with azathioprine (AZA) from January 2010 to March 2016 were entered in a prospectively maintained database, and the AEs which led to the permanent discontinuation of the drug were reported.Two hundred and fifty three patients were included. Median total follow-up was 32 months (range: 0.2-75 months). At the end of the study, AZA was discontinued in 160 patients (63.2%). The main reason leading to drug withdrawal was the occurren…

Peripheral blood stem cell (PBSC) mobilization with chemotherapy followed by sequential IL-3 and G-CSF administration in extensively pretreated patie…

1998

Extensive pretreatment has been identified as a significant risk factor for failure of sufficient PBSC mobilization. From published data and our own experience we defined pretreatment variables which render patients at risk for not collecting at least 2.5 x 10(6) CD34-positive cells per kg bodyweight (BW). These variables were previous unsuccessful PBSC mobilization trial, previous large field radiotherapy, four or more cycles of myelosuppressive chemotherapy regimens, and combinations of extended field radiotherapy plus chemotherapy. Based on these inclusion criteria we treated 19 patients with disease-specific conventional-dose chemotherapy followed by sequential subcutaneous administrati…

Monitoring of alphatorquevirus DNA levels for the prediction of immunosuppression-related complications after kidney transplantation

2019

The replication kinetics of nonpathogenic anelloviruses belonging to the Alphatorquevirus genus (such as torque teno virus) might reflect the overall state of posttransplant immunosuppression. We analyzed 221 kidney transplant (KT) recipients in whom plasma alphatorquevirus DNA load was quantified by real-time polymerase chain reaction at baseline and regularly through the first 12 posttransplant months. Study outcomes included posttransplant infection and a composite of opportunistic infection and/or de novo malignancy (immunosuppression-related adverse event [iRAE]). Alphatorquevirus DNA loads at month 1 were higher among patients who subsequently developed posttransplant infection (P  = …

Post-infantile giant cell hepatitis in patients with primary sclerosing cholangitis and autoimmune hepatitis.

2008

In post-infancy, multinucleated giant cell hepatitis is rare. Various conditions and diseases associated with post-infantile giant cell hepatitis have been described, but the pathogenesis remains unknown. In this paper we review the case reports of four patients (3 male, 1 female; aged 22 to 32 years) with primary sclerosing cholangitis and autoimmune hepatitis. The follow-up ranges from five to seven years. All patients showed cholestasis and repeated elevation of hepatic transaminases. Patients with viral infections, metabolic disorders and toxic influences were excluded. Histopathology of liver tissue in all four patients revealed giant cell formation with up to 20 nuclei in 20-70% of al…
