The deletion of six amino acids at the C-terminus of the alpha 1 (II) chain causes overmodification of type II and type XI collagen: further evidence…
1996
We have identified an 18 bp deletion in exon 49 of the type II procollagen gene (COL2A1) in a patient with Kniest dysplasia. The deletion is located at the very C-terminus of the helical domain and removes two of three Gly-Pro-Pro triplets at positions 1007-1012, which are thought to be involved in helix formation and stability. Morphological investigation of an iliac crest biopsy showed large inclusions in the endoplasmic reticulum of chondrocytes, reflecting impaired secretion of type II collagen. Electrophoretic analysis of collagens extracted from cartilage or synthesised by cultured chondrocytes showed that type II and also type XI procollagen molecules containing mutant alpha 1 (II) c…
Frontotemporal dementia: the post-tau era.
2006
As scientists have begun to decipher the molecular genetic bases of hereditary frontotemporal dementia (FTD), it has become clear that the biology of these human neurodegenerative diseases has a complexity not previously suspected. FTD has been found to be linked to several chromosomal loci including those in chromosome 9, chromosome 17, and chromosome 3. The article by Guyant-Marechal et al. in this issue of Neurology reports the clinical, pathologic, and molecular characteristics of a form of FTD associated with inclusion body myopathy and Paget disease of the bone observed in members of two families and expands our knowledge on genetically determined FTD.1 The disorder is associated with…
Gastric α-synuclein immunoreactive inclusions in Meissner's and Auerbach's plexuses in cases staged for Parkinson's disease-related brain pathology
2005
The progressive degenerative process associated with sporadic Parkinson's disease (sPD) is characterized by formation of alpha-synuclein-containing inclusion bodies in a few types of projection neurons in both the enteric and central nervous systems (ENS and CNS). In the brain, the process apparently begins in the brainstem (dorsal motor nucleus of the vagal nerve) and advances through susceptible regions of the basal mid-and forebrain until it reaches the cerebral cortex. Anatomically, all of the vulnerable brain regions are closely interconnected. Whether the pathological process begins in the brain or elsewhere in the nervous system, however, is still unknown. We therefore used immunocyt…
Validation of clinical scoring systems ART and ABCR after transarterial chemoembolization of hepatocellular carcinoma.
2016
Abstract Purpose To perform an external validation of the Assessment for Retreatment with Transarterial Chemoembolization (ART) and α-fetoprotein (AFP), Barcelona Clinic Liver Cancer (BCLC), Child–Pugh, and response (ABCR) scores and to compare them in terms of prognostic power. Materials and Methods From 2000 to 2015, 871 patients with hepatocellular carcinoma underwent transarterial chemoembolization at a tertiary referral hospital, and 176 met all inclusion and exclusion criteria for both scores and were analyzed. Nineteen percent (n = 34) had BCLC stage A disease and 81% had stage B disease. Thirty-nine patients (22%) presented with elevated AFP levels. Overall survival was calculated. …
Ultrastructural Pathology of Eccrine Sweat Gland Epithelial Cells in Globoid Cell Leukodystrophy
1993
Three of four children were recognized by deficient β-galactocerebrosidase activities as having globoid cell leukodystrophy inclusions in sweat gland epithelial cells, similar in ultrastructure to those seen in Schwann cells. This observation in globoid cell leukodystrophy emphasizes the need to include sweat gland epithelial cells in examinations of skin in globoid cell leukodystrophy, as well as in any neurometabolic disorder. ( J Child Neurol 1993;8:171-174).
DJ-1 mutations and parkinsonism-dementia-amyotrophic lateral sclerosis complex.
2005
Mutations in DJ-1 gene have been recently shown to cause autosomal recessive early-onset Parkinson’s disease (EOPD) in a large Dutch family and in a small consanguineous Italian family.1 Subsequent to this initial finding, several additional DJ-1 mutations were identified in subjects with EOPD.2–6 We describe a family from southern Italy with three brothers affected by a complex disorder characterized by early-onset parkinsonism-dementia-amyotrophic lateral sclerosis (EOPD-D-ALS). The analysis of the DJ-1 gene showed a novel homozygous mutation (E163K) in exon 7 and a novel homozygous mutation (g.168_185dup) in the promoter region of this gene in living affected subjects
Intranuclear nemaline rod myopathy
2006
The clinical, pathologic, and genetic findings of a boy with intranuclear nemaline rod myopathy are described. Serial muscle biopsies revealed myocyte nuclei containing inclusions that were immunoreactive for α-actinin and increased with age. Genetic analysis revealed a Val163Leu ACTA1 mutation previously associated with nemaline rod myopathy. Although initially delayed, he has reached all milestones and remains stable. These findings suggest intranuclear rods may increase with time and do not necessarily imply a poor prognosis. Muscle Nerve, 2006
The development and psychometric validation of an instrument to evaluate nurses' attitudes towards communication with the patient (ACO)
2017
Background Patient communication is a key skill for nurses involved in clinical care. Its measurement is a complex phenomenon that can be addressed through attitude evaluation. Objectives To develop and psychometrically test a measure of nurses' attitudes towards communication with patients (ACO), to study the relationship between these dimensions, and to analyse nursing attitudes. Design To develop and psychometrically test the ACO questionnaire. Settings All hospitals in the province of Valencia were invited by e-mail to distribute the ACO instrument. Ten hospitals took part in the study. Participants The study population was composed of a convenience sample of 400 hospital nurses on gene…
Blood eosinophils and treatment response in hospitalized exacerbations of chronic obstructive pulmonary disease: A case-control study
2015
Background: In outpatients with chronic obstructive pulmonary disease (COPD), blood eosinophilia is considered as a biomarker of response to systemic corticosteroid therapy. However, little is known on whether blood eosinophilia is also predictive of positive clinical outcome in severe acute exacerbations of COPD requiring hospitalization. We hypothesized that blood eosinophil-positive severe acute exacerbations of COPD differ from eosinophil-negative ones in terms of response to therapy and clinical outcomes. Methods: To test our experimental hypothesis, we retrospectively analyzed medical records of patients with COPD admitted to our ward because of severe exacerbation, over a two-year pe…
Epidermal inclusion cyst of the penis after urethroplasty causing an urethro-cutaneous fistula: a first case report
2014
Penile epidermal cysts are uncommon. We report a pediatric case of epidermal inclusion cyst of the penis after urethroplasty, responsible of the appearance of an urethro-cutaneous fistula. In our opinion, surgical excision of epidermal inclusion cyst after urethroplasty must be performed as quickly as possible to avoid occurrence of postoperative complications.
