Hsp60 and Hsp10 increase in colon mucosa of Crohn's disease and ulcerative colitis.
2010
The purpose of this work was to determine in colon mucosa of Crohn’s disease (CD) and ulcerative colitis (UC) in relapse: a) the levels of the chaperonins Hsp60 and Hsp10; b) the quantity of inflammatory cells; and c) if the levels of chaperonins parallel those of inflammation cells. Twenty cases of CD and UC and twenty normal controls (NC) were studied using immunohistochemistry, Western blotting and immunofluorescence. Immunohistochemically, Hsp60 and Hsp10 were increased in both inflammatory bowel diseases (IBD) compared to NC. These results were confirmed by Western blotting. Hsp60 and Hsp10 occurred in the cytoplasm of epithelial cells in CD and UC but not in NC. Hsp60 and Hsp10 co-loc…
Rare NLRP12 variants associated with the NLRP12-autoinflammatory disorder phenotype: an Italian case series.
2013
Replication of interleukin 23 receptor and autophagy-related 16-like 1 association in adult- and pediatric-onset inflammatory bowel disease in Italy.
2008
AIM: To investigate gene variants in a large Italian inflammatory bowel disease (IBD) cohort, and to analyze the correlation of sub-phenotypes (including age at diagnosis) and epistatic interaction with other IBD genes. METHODS: Total of 763 patients with Crohn's disease (CD, 189 diagnosed at age < 19 years), 843 with ulcerative colitis (UC, 179 diagnosed < 19 years), 749 healthy controls, and 546 healthy parents (273 trios) were included in the study. The rs2241880 [autophagy-related 16-like 1 (ATG16L1)], rs11209026 and rs7517847 [interleukin 23 receptor (IL23R)], rs2066844, rs2066845, rs2066847 (CARD15), rs1050152 (OCTN1), and rs2631367 (OCTN2) gene variants were genotyped. RESULTS: The f…
Functional pain in hospitalised and school children
2012
Aim. Aim of the study was to recognise the role of psychological disagreement in children and adolescents suffering from functional pain. Methods. Two groups of children, adolescents and their parents were interviewed: group H (hospitalized patients), group S (students, at school). Suitable investigations excluded organic lesions. The following data were analysed: 1) presence of pain in relation with: i) sex and age; ii) relation with parents, brothers, other relatives, schoolfellows; 2) efficacy of possible treatments. Results. Group H: 194 patients, median age 10 years; 134 referred pain: 62 out of 92 males and 72 out of 102 females; location of pain: abdomen, limbs, head, back. Family di…
Expanding the phenotype associated to KMT2A variants: overlapping clinical signs between Wiedemann–Steiner and Rubinstein–Taybi syndromes
2020
Lysine-specific methyltransferase 2A (KMT2A) is responsible for methylation of histone H3 (K4H3me) and contributes to chromatin remodeling, acting as “writer” of the epigenetic machinery. Mutations in KMT2A were first reported in Wiedemann–Steiner syndrome (WDSTS). More recently, KMT2A variants have been described in probands with a specific clinical diagnosis comprised in the so-called chromatinopathies. Such conditions, including WDSTS, are a group of overlapping disorders caused by mutations in genes coding for the epigenetic machinery. Among them, Rubinstein–Taybi syndrome (RSTS) is mainly caused by heterozygous pathogenic variants in CREBBP or EP300. In this work, we used next generati…
Transient hepatic nodular lesions associated with patent ductus venosus in preterm infants.
2010
We report on two cases of low-birth-weight preterm infants with patent ductus venosus associated with hepatic hypoechoic lesions of the fourth segment in an otherwise normal liver. Although tumorlike hepatic lesions have been previously reported in association with portosystemic shunts in children and adults, they were never described in preterm infants during physiological patency of ductus venosus. In our patients, hepatic lesions disappeared shortly after the spontaneous ductus closure. Physiopathologic interactions are discussed regarding altered portal blood supply caused by ductus venosus shunt.
Oro-facial aspects of leprosy : report of two cases with literature review
2009
Leprosy is a chronic infectious disease affecting primarily the skin, peripheral nerves, respiratory system and the eyes. Leprosy induces various types of clinical presentation affecting the patient´s immune response. Cellmediated immunity is considered to be the crucial defence against the disease and the magnitude of this immunity defines the extent of the disease. The article presents two case reports of manifestations of leprosy in the oro-facial region, with a brief review of various other important oro-facial manifestations of leprosy. The first report deals with granulomatous nodules in the palate while the second report presents bilateral facial palsy in leprosy patients. Both the r…
Dyke-Davidoff-Masson syndrome: case report of fetal unilateral ventriculomegaly and hypoplastic left middle cerebral artery
2013
Prenatal ultrasonographic detection of unilateral cerebral ventriculomegaly arises suspicion of pathological condition related to cerebrospinal fluid flow obstruction or cerebral parenchimal pathology. Dyke-Davidoff-Masson syndrome is a rare condition characterized by cerebral hemiatrophy, calvarial thickening, skull and facial asymmetry, contralateral hemiparesis, cognitive impairment and seizures. Congenital and acquired types are recognized and have been described, mainly in late childhood, adolescence and adult ages. We describe a female infant with prenatal diagnosis of unilateral left ventriculomegaly in which early brain MRI and contrast enhanced-MRI angiography, showed cerebral left…
Wilms' tumor in patients with 9q22.3 microdeletion syndrome suggests a role for PTCH1 in nephroblastomas
2012
Nephroblastoma (Wilms' tumor; WT) is the most common renal tumor of childhood. To date, several genetic abnormalities predisposing to WT have been identified in rare overgrowth syndromes. Among them, abnormal methylation of the 11p15 region, GPC3 and DIS3L2 mutations, which are responsible for Beckwith-Wiedemann, Simpson-Golabi-Behmel and Perlman syndromes, respectively. However, the underlying cause of WT remains unknown in the majority of cases. We report three unrelated patients who presented with WT in addition to a constitutional 9q22.3 microdeletion and dysmorphic/overgrowth syndrome. The size of the deletions was variable (ie, from 1.7 to 8.9 Mb) but invariably encompassed the PTCH1 …
What’s the name? Weight stigma and the battle against obesity
2020
AbstractChildhood obesity has spread worldwide, it is on the rise, starts earlier and is more severe, despite all treatment attempts.According to recent studies, weight stigma is a factor that can hinder the success of therapies. Healthcare workers, mainly paediatricians, need to feel the urgency of anti-stigma training. The use of non-stigmatizing terminologies and images in various areas (school, sports clubs, healthcare, media, society in general) can improve disease management.
