The 2015 European Thyroid Association Guidelines on diagnosis and treatment of endogenous subclinical hyperthyroidism
2014
Endogenous subclinical hyperthyroidism (SHyper) is caused by Graves' disease, autonomously functioning thyroid nodules and multinodular goitre. Its diagnosis is based on a persistently subnormal serum thyroid-stimulating hormone (TSH) level with free thyroid hormone levels within their respective reference intervals. In 2014 the European Thyroid Association Executive Committee, given the controversies regarding the treatment of Endo SHyper, formed a task force to develop clinical practice guidelines based on the principles of evidence-based medicine. The task force recognized that recent meta-analyses, including those based on large prospective cohort studies, indicate that SHyper is associ…
Complex regional pain syndrome-significant progress in understanding.
2015
Research into complex regional pain syndrome (CRPS) has made significant progress. First, there was the implementation of the official IASP "Budapest" diagnostic criteria. It would be desirable to also define exclusion and outcome criteria that should be reported in studies. The next step was to recognize the complex pathophysiology. After trauma, some inflammation is physiological; in acute CRPS, this inflammation persists for months. There is an abundance of inflammatory and a lack of anti-inflammatory mediators. This proinflammatory network (cytokines and probably also other mediators) sensitizes the peripheral and spinal nociceptive system, it facilitates the release of neuropeptides fr…
Enhanced Activity of Meprin-α, a Pro-Migratory and Pro-Angiogenic Protease, in Colorectal Cancer
2011
Meprin-α is a metalloprotease overexpressed in cancer cells, leading to the accumulation of this protease in a subset of colorectal tumors. The impact of increased meprin-α levels on tumor progression is not known. We investigated the effect of this protease on cell migration and angiogenesis in vitro and studied the expression of meprin-α mRNA, protein and proteolytic activity in primary tumors at progressive stages and in liver metastases of patients with colorectal cancer, as well as inhibitory activity towards meprin-α in sera of cancer patient as compared to healthy controls. We found that the hepatocyte growth factor (HGF)- induced migratory response of meprin-transfected epithelial c…
Cerebrospinal Fluid Analysis in Multiple Sclerosis Diagnosis: An Update
2019
Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system (CNS) with brain neurodegeneration. MS patients present heterogeneous clinical manifestations in which both genetic and environmental factors are involved. The diagnosis is very complex due to the high heterogeneity of the pathophysiology of the disease. The diagnostic criteria have been modified several times over the years. Basically, they include clinical symptoms, presence of typical lesions detected by magnetic resonance imaging (MRI), and laboratory findings. The analysis of cerebrospinal fluid (CSF) allows an evaluation of inflammatory processes circumscribed to the CNS and reflects chan…
Long-Term Outcome of Cognitive Impairment in Bipolar Disorder
2011
OBJECTIVE: To evaluate the longitudinal course and outcome of cognitive deficits and their clinical correlates in bipolar disorder. METHOD: One hundred thirteen participants (68 patients and 45 healthy controls) were assessed by the means of a neuropsychological battery targeting attention, psychomotor speed, verbal memory, and executive functions at baseline: 68 euthymic outpatients with a DSM-IV diagnosis of bipolar disorder (53 bipolar I and 15 bipolar II) were enrolled at the Bipolar Disorder Unit of the Hospital Clinic of Barcelona. Forty-five patients completed the follow-up. The assessments started in February 1999 and finished in July 2010. The primary outcome of the study was the c…
Lymphocytic Mitochondrial Aconitase Activity is Reduced in Alzheimer's Disease and Mild Cognitive Impairment
2015
Background: Specific mechanisms behind the role of oxidative/nitrosative stress and mitochondrial dysfunction in Alzheimer's disease (AD) pathogenesis remain elusive. Mitochondrial aconitase (ACO2) is a Krebs cycle enzyme sensitive to free radicalmediated damage. Objective: We assessed activity and expression of ACO2 extracted from blood lymphocytes of subjects with AD, mild cognitive impairment (MCI), older adults with normal cognition (OCN, age >= 65 years), and younger adults with normal cognition (YCN, age < 65 years). Plasma levels and activities of antioxidants were also measured. Methods: Blood samples were collected from 28 subjects with AD, 22 with MCI, 21 OCN, and 19 YCN. ACO2 act…
Chronic progressive external ophthalmoplegia with a novel mitochondrial DNA deletion and a mutation in the tRNALEU(UUR) gene
1999
Large-scale deletions and point mutations of the mitochondrial DNA are generally accepted as being involved in the pathogenesis of diseases associated with mitochondrial encephalomyopathies such as Kearns-Sayre syndrome and chronic progressive external ophthalmoplegia (CPEO). We screened suspected patients using polymerase chain reaction techniques, Southern blot analyses, and muscle biopsy specimens. We report on a novel 4,953-base pair deletion associated with a familial occurrence of a tRNA Leu(UUR) T3250C point mutation in a young female patient clinically diagnosed with CPEO. This deletion is not flanked by direct repeats, so slip replication and homologous recombination do not seem li…
Abstract A42: miR34a: A valuable indicator of differential outcome of Ewing sarcoma patients with complex functions
2014
Abstract The identification of reliable indicators of prognosis, which may allow the stratification of patients according to different risk at diagnosis isan important aspect of translational research in Ewing sarcoma (ES). In this paper, we validated our previous evidence showing how expression of miR34a in ES tumor samples at diagnosis was signficantly associated with tumor progression (Nakatani F. J Pathol 2012). Here we analyzed a different series of speciments derived from very controlled and homogeneously treated non-metastatic ES patients, and we compared evaluation of miR34a by RT-PCR using frozen samples with that obtained by in situ hybridization on paraffin-embedded samples . The…
Therapy with lamivudine and steroids in a patient with acute hepatitis B and rapidly progressive glomerulonephritis.
2006
To the Editor: Tang et al.1 recently reported that lamivudine (LAM) improves renal outcome in patients with chronic hepatitis B virus (HBV) infection and membranous nephropathy. We would like to add our experience on acute hepatitis B and rapidly progressive glomerulonephritis.
