Diagnostic intracranial pressure monitoring and surgical management in idiopathic normal pressure hydrocephalus: a 6-year review of 214 patients.

Objective: To review our experience of managing idiopathic normal pressure hydrocephalus (iNPH) during the 6-year period from 2002 to 2007, when intracranial pressure (ICP) monitoring was part of the diagnostic workup.

Methods: The review includes all iNPH patients undergoing diagnostic ICP monitoring during the years 2002 to 2007. Clinical grading was done prospectively using a normal pressure hydrocephalus (NPH) grading scale (scores from 3 to 15).

Chondrogenesis in a hyaluronic acid scaffold: comparison between chondrocytes and MSC from bone marrow and adipose tissue.

Treatment of focal lesions of the articular cartilage of the knee using chondrocytes in a hyaluronic acid (HA) scaffold is already being investigated in clinical trials. An alternative may be to use mesenchymal stem cells (MSC). We have compared articular chondrocytes with MSC from human bone marrow (BM) and adipose tissue (AT), all cultured in HA scaffolds, for their ability to express genes and synthesize proteins associated with chondrogenesis.

Changing the diagnosis from epilepsy to PNES: patients' experiences and understanding of their new diagnosis.

Objective: To describe patients' experiences when diagnosed with psychogenic non-epileptic seizures (PNES).

Methods: The study was based on in-depth interviews with ten patients, previously diagnosed with epilepsy and treated with antiepileptic drugs (AEDs) whose seizures were subsequently defined as PNES. The empirical material was analyzed by systematic text condensing strategies within the interpretative tradition.

Phenotypic and genomic characterization of pneumococcus-like streptococci isolated from HIV-seropositive patients.

Accurate differentiation between pneumococci and other viridans streptococci is essential given their differences in clinical significance. However, classical phenotypic tests are often inconclusive, and many examples of atypical reactions have been reported. In this study, we applied various phenotypic and genotypic methods to discriminate between a collection of 12 streptococci isolated from the upper respiratory tract of HIV-seropositive individuals in 1998 and 1999.

Genome-wide association analysis in primary sclerosing cholangitis.

Background & Aims: We aimed to characterize the genetic susceptibility to primary sclerosing cholangitis (PSC) by means of a genome-wide association analysis of single nucleotide polymorphism (SNP) markers.

Methods: A total of 443,816 SNPs on the Affymetrix SNP Array 5.0 (Affymetrix, Santa Clara, CA) were genotyped in 285 Norwegian PSC patients and 298 healthy controls.

Impaired glucose homeostasis in renal transplant recipients receiving basiliximab.

Background: The pathogenesis of new onset diabetes after transplantation (NODAT) is multifactorial. Suppression of regulatory T lymphocytes may have a negative impact on pancreatic beta-cells. Induction with basiliximab affects regulatory T-cell function and may therefore, theoretically, also affect glucose homeostasis in renal transplant recipients.

Critical roles of complement and antibodies in host defense mechanisms against Neisseria meningitidis as revealed by human complement genetic deficiencies.

Certain complement defects are associated with an increased propensity to contract Neisseria meningitidis infections. We performed detailed analyses of complement-mediated defense mechanisms against N. meningitidis 44/76 with whole blood and serum from two adult patients who were completely C2 or C5 deficient.

Gene expression profiles classify human osteosarcoma xenografts according to sensitivity to doxorubicin, cisplatin, and ifosfamide.

Purpose: In osteosarcoma, aggressive preoperative and postoperative multidrug chemotherapy given to all patients has improved patient survival rate to the present level of approximately 60%. However, no tumor marker is available that reliably can identify those patients who will or will not respond to chemotherapy.

Experimental Design: In an attempt to find leads to such markers, we have obtained microarray gene expression profiles from a panel of 10 different human osteosarcoma xenografts and related the results to their sensitivity to ifosfamide, doxorubicin, and cisplatin.

Increased production of CXCL16 in experimental and clinical heart failure: a possible role in extracellular matrix remodeling.

Background: Inflammation has been implicated in the pathogenesis of heart failure (HF), but knowledge about the production and role of inflammatory actors remains incomplete. On the basis of its role in vascular inflammation, vascular proliferation, and matrix degradation, we hypothesized a role for the chemokine CXCL16 in the pathogenesis of myocardial remodeling and development of HF.

Methods And Results: Our main findings were (1) patients with chronic HF (n=188) had increased plasma levels of CXCL16, which correlated with disease severity.

Maternal characteristics and pregnancy outcomes in women presenting with decreased fetal movements in late pregnancy.

Objective: 'Normal' fetal activity is recognized as a sign of fetal well-being and concerns for decreased fetal movements is a frequent cause of non-scheduled antenatal visits. The aim of this study was to identify maternal characteristics in women presenting decreased fetal movements in a total population, to identify the risk of adverse outcomes and assess the management provided.

Design: Prospective population-based cohort.

Variants of the genes encoding AQP4 and Kir4.1 are associated with subgroups of patients with temporal lobe epilepsy.

Objective: The etiopathogenesis of temporal lobe epilepsy (TLE) and its subgroups - mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) and TLE with antecedent febrile seizures (TLE-FS) - is poorly understood. It has been proposed that the water channel aquaporin-4 (AQP4) and the potassium channel Kir4.1 (KCNJ10 gene) act in concert to regulate extracellular K(+) homeostasis and that functional alterations of these channels influence neuronal excitability.

Can persistent drop foot after calf muscle lengthening be predicted preoperatively?

Unlabelled: Calf muscle lengthening usually corrects equinus gait satisfactorily in stance. While in swing, the foot remains in drop foot in approximately half the limbs. The aim of this study was to evaluate if any preoperative clinical findings or kinematic and kinetic data could predict the outcome regarding drop foot.

BayesPI - a new model to study protein-DNA interactions: a case study of condition-specific protein binding parameters for Yeast transcription factors.

Background: We have incorporated Bayesian model regularization with biophysical modeling of protein-DNA interactions, and of genome-wide nucleosome positioning to study protein-DNA interactions, using a high-throughput dataset. The newly developed method (BayesPI) includes the estimation of a transcription factor (TF) binding energy matrices, the computation of binding affinity of a TF target site and the corresponding chemical potential.

Results: The method was successfully tested on synthetic ChIP-chip datasets, real yeast ChIP-chip experiments.

Evaluation of cell surface expression of phosphatidylserine in ovarian carcinoma effusions using the annexin-V/7-AAD assay: clinical relevance and comparison with other apoptosis parameters.

Phosphatidylserine cell surface exposure during apoptosis can be detected by its binding to the protein annexin-V. We investigated annexin-V expression in 76 ovarian carcinoma effusions using flow cytometry. Results were analyzed for association with clinicopathologic parameters and survival.

CD14 inhibition efficiently attenuates early inflammatory and hemostatic responses in Escherichia coli sepsis in pigs.

Sepsis is a severe infection-induced systemic inflammatory syndrome. Inhibition of downstream inflammatory mediators of sepsis, e.g.

How children with cancer communicate and think about symptoms.

Background: For clinicians to effectively help children with their illness and symptoms, it is important to communicate with them in a language they can understand.

Methods: This study investigates how well children with cancer and healthy children understood 44 symptom terms; their thoughts about these symptoms in terms of causes, consequences, and cures; and what other terms the children use to express these symptoms. It also explores if there are differences in understanding and thoughts about symptoms between children who have the experience of cancer and those who do not.

Adrenomedullin is increased in alveolar macrophages and released from the lungs into the circulation in severe heart failure.

Adrenomedullin (AM) is a potent vasorelaxing peptide with natriuretic, diuretic, and growth inhibitory properties. Plasma concentrations and myocardial AM expression are increased in heart failure (HF). Since AM and AM binding sites are abundantly expressed in the lungs, we investigated to what extent pulmonary AM and AM receptor subtypes [CRLR/RAMP2 (AM1) and CRLR/RAMP3 (AM2)] are changed in HF and whether the lungs contribute to the increased plasma concentrations of AM reported in HF.

Noninvasive separation of large, medium, and small myocardial infarcts in survivors of reperfused ST-elevation myocardial infarction: a comprehensive tissue Doppler and speckle-tracking echocardiography study.

Background: The objective of the study was to evaluate the ability of established and new parameters of global systolic left ventricle function to estimate myocardial infarct size. Increasing infarct extent is associated with impaired prognosis in chronic ischemic heart disease. Systolic myocardial deformation is a complex 3D process that is mainly influenced by the amount and transmural distribution of viable myocardium.

The down-stream effects of mannan-induced lectin complement pathway activation depend quantitatively on alternative pathway amplification.

Complement activation plays an important role in human pathophysiology. The effect of classical pathway activation is largely dependent on alternative pathway (AP) amplification, whereas the role of AP for the down-stream effect of mannan-induced lectin pathway (LP) activation is poorly understood. In normal human serum specific activation of LP was obtained after exposure to a wide concentration range of mannan on the solid phase.

Costs and reimbursement gaps after implementation of third-generation left ventricular assist devices.

Background: The purpose of this study was to compare and contrast total hospital costs and subsequent reimbursement of implementing a new program using a third-generation left ventricular assist device (LVAD) in Norway.

Methods: Between July 2005 and March 2008, the total costs of treatment for 9 patients were examined. Costs were calculated for three periods-the pre-implantation LVAD phase, the LVAD implantation phase and the post-implantation LVAD phase-as well as for total hospital care.

Synergistic anti-cancer effects of immunotoxin and cyclosporin in vitro and in vivo.

Background: The clinical use of immunotoxins (ITs) has been hampered by hepatotoxicity, and the induction of a strong human-anti-IT response. The human-anti-IT response results in neutralisation of the immunoconjugates, rendering repetitive treatment inefficacious.

Methods: We evaluated the combination of cyclosporin A (CsA) with various Pseudomonas exotoxin A-based ITs in human breast, cervical, and prostate cancer cell lines measured by protein synthesis, cell viability, and TUNEL assay.

Long-term stability of extemporaneously prepared captopril oral liquids in glass bottles.

Purpose: The long-term stability of captopril in extemporaneously prepared oral liquids was studied.

Methods: Captopril solutions of 1 and 5 mg/mL were prepared in sterile water for irrigation with sorbitol, disodium edetate, and sodium benzoate. The samples were stored in 100-mL amber glass bottles with a headspace of air at 22 degrees C for 12 months.
