Geographical pattern of chronic liver diseases in Italy: Results from two pooled national surveys
2019
Background: The information on the geographical characteristics of chronic liver diseases (CLD) in Italy is out-dated. Aim: To provide up-dated information on the geographical pattern of patients with CLD born in Italy. Methods: Patients with CLD were enrolled in two national surveys performed in 2001 and 2014, which prospectively recruited subjects aged ≥18 years referring to Italian liver units located throughout the country that apply a similar clinical approach and analytical methods. Results: The total number of patients enrolled was 11,676. Alcohol-related CLD was more frequently observed in northern/central areas (25.0% vs. 20.7%, p < .001), while HBV-related (15.4% vs. 13.3%, p =…
Liver cirrhosis associated with heterozygous alpha-1-antitrypsin deficiency type Pi MS and autoimmune features.
1995
Patients with homozygous protease inhibitor (Pi) type ZZ or a few rare M-like types may develop liver cirrhosis due to intracellular storage of alpha-antitrypsin (AAT), whereas some patients with heterozygous Pi MZ or SZ normally present with transient abnormal liver function tests in childhood. We report a 42-year-old obese patient who developed liver cirrhosis in association with heterozygous Pi MS (AAT) deficiency. Immunohistological and electron microscope examination showed storage of AAT in the hepatocytes. Interestingly, autoimmune features in this patient suggest that abnormal immune responses may contribute to the pathology of chronic liver disease.
Anti-SARS-CoV-2 IgA and IgG in human milk after vaccination is dependent on vaccine type and previous SARS-CoV-2 exposure: a longitudinal study
2022
Breast milk is a vehicle to transfer protective antibodies from the lactating mother to the neonate. After SARS-CoV-2 infection, virus-specific IgA and IgG have been identified in breast milk, however, there are limited data on the impact of different COVID-19 vaccine types in lactating women. This study is aimed to evaluate the time course of induction of SARS-CoV-2-specific IgA and IgG in breast milk after vaccination.
Bilateral cystic pulmonary glial heterotopia and palatinal teratoma causing respiratory distress in an infant
2009
We report on a male infant with extensive, bilateral cystic and solid lung lesions who presented postnatally with respiratory distress caused by bilateral cystic lung lesions. Parenchyma-sparing resections were performed. Histology revealed the presence of neuroglial cell-lined cysts and glial nodules. In addition, a neural element containing palatinal teratoma was detected and excised. Based on previously published cases, the pathogenesis and clinical features of pulmonary neuroglial heterotopia are discussed.
Colorectal cancer with microsatellite instability: Right-sided location and signet ring cell histology are associated with nodal metastases, and extr…
2021
Colorectal cancer (CRC) with microsatellite instability (MSI) accounts for 15-18 % of all CRCs and represents the category with the best prognosis. This study aimed at determining any possible clinical/pathological features associated with a higher risk of nodal metastasization in MSI-CRC, and at defining any possible prognostic moderators in this setting. All surgically resected CRCs of the last 20 years (mono-institutional series) with a PCR-based diagnosis of MSI, with and without nodal metastasis, have been retrieved for histological review, which was performed following WHO guidelines. Furthermore, the most important prognostic moderators have been investigated with a survival analysis…
Clinical and neuroimaging findings in 33 patients with MCAP syndrome: A survey to evaluate relevant endpoints for future clinical trials
2021
Megalencephaly-CApillary malformation-Polymicrogyria (MCAP) syndrome results from somatic mosaic gain-of-function variants in PIK3CA. Main features are macrocephaly, somatic overgrowth, cutaneous vascular malformations, connective tissue dysplasia, neurodevelopmental delay, and brain anomalies. The objectives of this study were to describe the clinical and radiological features of MCAP, to suggest relevant clinical endpoints applicable in future trials of targeted drug therapy. Based on a French collaboration, we collected clinical features of 33 patients (21 females, 12 males, median age of 9.9 years) with MCAP carrying mosaic PIK3CA pathogenic variants. MRI images were reviewed for 21 pat…
The Primitive Palmomental Reflex in Amyotrophic Lateral Sclerosis
2017
<b><i>Background and Purpose:</i></b> The palmomental reflex (PMR) is a primitive reflex that might be released due to inhibition in adulthood. It has been associated with several neurodegenerative conditions. The aim of the present study was to evaluate the frequency of PMR in amyotrophic lateral sclerosis (ALS). <b><i>Patients and Methods:</i></b> Non-demented ALS patients (<i>n</i> = 179) were recruited. Two groups of disease controls were enrolled: (a) non-demented patients with other neurological disorders (NC;<i> n</i> = 86, mean age 60 ± 14 years); (b) healthy subjects, healthy controls (HC; <i>n</i> …
Double Retrotransverse Foramen of Atlas (C1)
2018
Background The retrotransverse foramen is a nonmetric variant of C1 that consists of an abnormal accessory foramen on the posterior root of the transverse process. Case Description During a study on the prevalence of the retrotransverse foramen in 150 dry C1 vertebrae, we observed an exceptional C1 (0.67%) with a right double retrotransverse foramen of the 14 C1 vertebrae (9.3%). This has not been reported previously in the literature. No osteogenic reaction and no degenerative signs were observed in this C1 with the double retrotransverse foramen. Conclusions Neurosurgeons should be aware of the possible presence of the “conventional” retrotransverse foramen and the “exceptional” double re…
Phenotypical features of two patients diagnosed with PHARC syndrome and carriers of a new homozygous mutation in the ABHD12 gene.
2018
Abstract PHARC (Polyneuropathy, Hearing loss, Ataxia, Retinitis pigmentosa and Cataracts) (MIM# 612674 ) is an autosomal recessive neurodegenerative disease caused by mutations in the ABHD12 gene. We evaluated two Spanish siblings affected with pes cavus, sensorimotor neuropathy, hearing loss, retinitis pigmentosa and juvenile cataracts in whom the genetic test of ABHD12 revealed a novel homozygous frameshift mutation, c.211_223del (p.Arg71Tyrfs*26). The earliest clinical manifestation in these patients was a demyelinating neuropathy manifested with a Charcot-Marie-Tooth phenotype over three decades. Progressive hearing loss, cataracts and retinitis pigmentosa appeared after the age of 30. …
Dental anomalies inside the cleft region in individuals with nonsyndromic cleft lip with or without cleft palate
2015
Background Individuals with non syndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment. The aim of this study was to investigate the prevalence of dental anomalies inside cleft area in a group of Brazilians with NSCL±P. Material and Methods Retrospective analysis of 178 panoramic radiographs of patients aged from 12 to 45 years old and without history of tooth extraction or orthodontic treatment was performed. Association between cleft type and the prevalence of dental anomalies was assessed by chi-square test with a significance level set at p≤ 0.05. Results Dental anomalies were fo…
