Laparoscopy versus open adrenalectomy in patients with solid tumor metastases: results of a multicenter European study
2020
Background: The outcome of adrenalectomy carried out by laparoscopy or open surgery for solid tumor metastases was assessed. Methods: A total of 317 patients with histologically confirmed adrenal metastatic disease collected from 30 centres in Europe underwent adrenalectomy by laparoscopy (n=146) or open laparotomy (n=171). Differences between laparoscopic and open adrenalectomy were assessed by a single Cox analysis for both procedures. Results: The median overall survival was 24.0 [95% confidence interval (CI): 21.4-26.6] months for open adrenalectomy and 45.0 (95% CI: 22.6-67.4) for laparoscopic adrenalectomy (P=0.008). Survival rates were 68%, 49%, 35% and 29% at 1, 2, 3 and 5 years for…
Minor Neurological Dysfunctions (MNDs) in Autistic Children without Intellectual Disability
2018
Background: Children with autism spectrum disorder (ASD) require neurological evaluation to detect sensory-motor impairment. This will improve understanding of brain function in children with ASD, in terms of minor neurological dysfunctions (MNDs). Methods: We compared 32 ASD children without intellectual disability (IQ ≥ 70) with 32 healthy controls. A standardized and age-specific neurological examination according to Touwen was used to detect the presence of MNDs. Particular attention was paid to severity and type of MNDs. Results: Children with ASD had significantly higher rates of MNDs compared to controls (96.9% versus 15.6%): 81.3% had simple MNDs (p < 0.0001) and 15.6% had comple…
Effect of Intravenous IgM-Enriched Immunoglobulins on Presepsin and Other Sepsis Biomarkers
2021
Patients in septic shock with low IgG and IgM serum concentrations have higher mortality rates compared to those with normal immunoglobulin levels and, therefore, there is a rational explanation to administer intravenous IgM-enriched immunoglobulins to septic patients in ICU. Aim of this study is to evaluate the effectiveness of intravenous IgM-enriched immunoglobulins in decreasing several sepsis biomarker concentrations. 26 sepsis patients were enrolled in this observational cohort study and Nitric Oxide, Endocan, Pentraxin and presepsin serum levels were measured during their first 3 days of ICU stay. The use of intravenous IgM-enriched immunoglobulins did not influence the temporal evol…
Bone marrow evaluation according to the PVSG and WHO criteria in 90 essential thrombocythemia (ET) patients treated with PEG interferon alpha-2b. Pre…
2005
Abstract Ninety ET patients diagnosed according to the PVSG criteria were enrolled in a phase II study (sponsored by the Schering-Plough Company) designed to evaluate the efficacy, safety and tolerability of a two years treatment with PEG Interferon alpha-2 b (PEG Intron). The patients, observed in 16 Italian Centres belonging to the GIMEMA Cooperative Group and judged at high risk, had been previously treated with cytoreductive (97%) and antiplatelet (91%) drugs. At the study start the patients, 60 F and 30 M, mean age 45 years, showed splenomegaly in 22% of cases. The Hematological Response (HR: PLT&lt;500 x109/L) was observed in 64/81 (79%) and 48/55 (87%) of the patients on PEG Intr…
Die Lungentuberkulose – aktuelle radiologische Diagnostik einer alten Krankheit
2000
Inzidenz. Abnehmende Inzidenzen aktiver Tuberkulose in den Industrielandern haben diese Erkrankung aus dem Bewusstsein vieler verdrangt. Dennoch stellt die Tuberkulose weiterhin weltweit die am haufigsten zum Tode fuhrende Infektionskrankheit dar. In den Industrielandern tragen Faktoren wie Einwanderungsbewegungen, zunehmende Verarmung und die Zunahme immunsupprimierter Patienten, insbesondere durch die HIV-Epidemie, dazu bei, dass ein Reservoir fur die Tuberkulose aufrecht erhalten wird. Diagnose. Eine fruhzeitige Diagnose ist wegen der spezifischen Therapiemoglichkeiten entscheidend fur den Krankheitsverlauf; im Falle von multiresistenten Stammen ist sie wichtig zur Verhinderung einer wei…
Imaging of VSOP labeled stem cells in agarose phantoms with susceptibility weighted and T2* weighted MR Imaging at 3T: determination of the detection…
2013
Objectives This study aimed to evaluate the detectability of stem cells labeled with very small iron oxide particles (VSOP) at 3T with susceptibility weighted (SWI) and T2* weighted imaging as a methodological basis for subsequent examinations in a large animal stroke model (sheep). Materials and Methods We examined ovine mesenchymal stem cells labeled with VSOP in agarose layer phantoms. The experiments were performed in 2 different groups, with quantities of 0–100,000 labeled cells per layer. 15 different SWI- and T2*-weighted sequences and 3 RF coils were used. All measurements were carried out on a clinical 3T MRI. Images of Group A were analyzed by four radiologists blinded for the num…
Principal component analysis and cluster analysis for measuring the local organisation of human atrial fibrillation
2001
The distribution of atrial electrogram types has been proposed to characterise human atrial fibrillation. The aim of this study was to provide computer procedures for evaluating the local organisation of intracardiac recordings during AF as an alternative to off-line manual classification. Principal components analysis (PCA) reduced the data set to a few representative activations, and cluster analysis (CA) measured the average dissimilarity between consecutive activations of an intracardiac signal. The data set consisted of 106 bipolar signals recorded on 11 patients during electrophysiological studies for catheter ablation. Performances of PCA and CA in distinguishing between organised (t…
Interhemispheric inhibition during mental actions of different complexity.
2013
International audience; Several investigations suggest that actual and mental actions trigger similar neural substrates. Yet, neurophysiological evidences on the nature of interhemispheric interactions during mental movements are still meagre. Here, we asked whether the content of mental images, investigated by task complexity, is finely represented in the inhibitory interactions between the two primary motor cortices (M1s). Subjects' left M1 was stimulated by means of transcranial magnetic stimulation (TMS) while they were performing actual or mental movements of increasing complexity with their right hand and exerting a maximum isometric force with their left thumb and index. Thus, we sim…
Pro-inflammatory cytokines and prostaglandins induce maturation of potent immunostimulatory dendritic cells under fetal calf serum-free conditions.
1998
Culture conditions for human dendritic cells (DC) have been developed by several laboratories. Most of these culture methods, however, have used conditions involving fetal calf serum (FCS) to generate DC in the presence of granulocyte-macrophage colony-stimulating factor and interleukin (IL)-4. Recently, alternative culture conditions have been described using an additional stimulation with monocyte-conditioned medium (MCM) and FCS-free media to generate DC. As MCM is a rather undefined cocktail, the yield and quality of DC generated by these cultures varies substantially. We report that a defined cocktail of tumor necrosis factor (TNF)-alpha, IL-1beta and IL-6 equals MCM in its potency to …
Single and Synergistic Effects of Type 2 Cytokines on Eosinophils and Asthma Hallmarks
2020
Abstract The type 2 cytokines IL-5, IL-13, and IL-4 play an important role in the induction and progression of asthma. According to the Global Initiative for Asthma guidelines, blood eosinophil numbers are one marker that helps to guide treatment decisions in patients suffering from severe forms of asthma. Effects of type 2 cytokines were analyzed, alone or in combination, on eosinophils in blood and other compartments and on the development of asthma symptoms. C57BL/6 mice received a single intranasal application of equimolar amounts of IL-5, IL-13, and IL-4, alone or in combination. Numbers, activation state, and migratory behavior of eosinophils in bone marrow (BM), blood, lung, and bron…
