Congenital hypopituitarism and multiple midline defects in a newborn with non-familial Cat Eye syndrome

2022

Abstract Background Cat eye syndrome (CES) is a rare chromosomal disease, with estimated incidence of about 1 in 100,000 live newborns. The classic triad of iris coloboma, anorectal malformations, and auricular abnormalities is present in 40% of patients, and other congenital defects may also be observed. The typical associated cytogenetic anomaly relies on an extra chromosome, derived from an inverted duplication of short arm and proximal long arm of chromosome 22, resulting in partial trisomy or tetrasomy of such regions (inv dup 22pter-22q11.2). Case presentation We report on a full-term newborn, referred to us soon after birth. Physical examination showed facial dysmorphisms, including …

Interstitial deletion of the long arm of chromosome 1 (1q 25-32): Clinical and endocrine features with a long term follow-up

2003

Deletion of long arm of chromosome 1 (1q-) is a rare condition with malformations of many organs (central nervous system, heart, kidney, etc.). Authors describe a young girl characterised by 1q 25-32 deletion, with severe intra- and extrauterine growth retardation, facial dismorphisms, multiple organ malformations. The patient is followed for a long-term clinical and endocrine evaluation, with evidence of hypoplastic hypophysis and multiple endocrine deficiency.

Chest Radiograph as Diagnostic Clue in a Floppy Infant

Detection of human papilloma virus (HPV) in liquid-based cervical samples. Correlation with protein p16INK4a expression.

2011

Artículo publicado en: Invest Clin 52(1): 3 - 14, 2011 La citología del cuello uterino en base líquida mejora la calidad de la muestra y el material residual podría ser utilizado para realizar pruebas complementarias, como la detección del virus papiloma humano (HPV) y estudio inmunocitoquímico de biomarcadores. El propósito de este estudio fue correlacionar la presencia de HPV y la inmunoexpresión de p16INK4a en las muestras citológicas en base líquida para examinar la utilidad de estas nuevas herramientas en la detección de cáncer de cuello uterino. Las pacientes incluidas (n=67) presentaban una citología anormal o patología cervical previa. La detección y genotipificación de HPV se reali…

The Correlation Between Abnormal Uterine Artery Flow in the First Trimester and Genetic Thrombophilic Alteration: A Prospective Case-Controlled Pilot…

2020

Introduction. Evaluation of the first trimester uterine artery flow can predict the development of obstetrical complications. A genotype, making women prone to microthrombi. constitutes the main known susceptibility factor for anomalous development of placenta. Our aim was to study whether polymorphisms of 10 genes leading to blood clotting abnormalities are related to abnormal uterine artery blood flow in the first trimester, and may predict placenta-related diseases. Material and methods. In primary analyses we included 19 singleton pregnancies with abnormal blood flow in the uterine arteries during the first trimester of gestation, and 24 matched control with normal flow patterns. All pa…

Congenital heart defects in newborns with apparently isolated single gastrointestinal malformation: A retrospective study.

2015

Abstract Background Congenital gastrointestinal system malformations/abdominal wall defects (GISM) may appear as isolated defects (single or complex), or in association with multiple malformations. The high incidence of association of GISM and congenital heart defects (CHD) in patients with syndromes and malformative sequences is known, but less expected is the association of apparently isolated single GISM and CHD. The aim of this study was to investigate the frequency of CHD in newborns with isolated GISM, and the possibility to modify the diagnostic-therapeutic approach just before the onset of cardiac symptoms or complications. Methods Anamnestic, clinical, and imaging data of newborns …

Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in…

2021

Abstract Background There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities. Methods The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group – KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clini…

A case of femoral-facial syndrome in a patient with autism spectrum disorders.

2011

The Femoral hypoplasia - unusual facies syndrome (FHUF) or Femoral - facial syndrome (FFS) was at first described in 1975. Up to now about 60 cases have been reported. According to our knowledge only 4 cases have had congenital central nervous system's malformations, furthermore the main stages of psychomotor development are almost always reported as normal or slightly altered in early childhood. We describe the first case of autism spectrum disorders (ASD) in a patient with FFS, emphasizing that this rare association could be one of many unrecognized underlying features.

Fraser syndrome: epidemiological study in a European population

2013

Fraser syndrome is a rare autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, laryngeal, and urogenital malformations. We present a population-based epidemiological study using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network of birth defect registries. Between January 1990 and December 2008, we identified 26 cases of Fraser syndrome in the monitored population of 12, 886, 464 births (minimal estimated prevalence of 0.20 per 100, 000 or 1:495, 633 births). Most cases (18/26 ; 69%) were registered in the western part of Europe, where the mean prevalence is 1 in 230, 695 births, compared to the prevalence 1 in 1, 091, 175 fo…

Nuclear Translocation of Mismatch Repair Proteins MSH2 and MSH6 as a Response of Cells to Alkylating Agents

2000

Mammalian mismatch repair has been implicated in mismatch correction, the prevention of mutagenesis and cancer, and the induction of genotoxicity and apoptosis. Here, we show that treatment of cells specifically with agents inducing O(6)-methylguanine in DNA, such as N-methyl-N'-nitro-N-nitrosoguanidine and N-methyl-N-nitrosourea, elevates the level of MSH2 and MSH6 and increases GT mismatch binding activity in the nucleus. This inducible response occurs immediately after alkylation, is long-lasting and dose-dependent, and results from translocation of the preformed MutSalpha complex (composed of MSH2 and MSH6) from the cytoplasm into the nucleus. It is not caused by an increase in MSH2 gen…
