Gluten-free diet impact on leptin levels in asymptomatic coeliac adolescents: one year of follow-up.
2006
Coeliac disease, daily more frequently diagnosed in our population, involves many organs also in oligosymptomatic patients and with an adequate nutritional regime. Possible endocrine implications include failure to thrive, pubertal delay and reproduction diseases due to deregulation of GH, FSH and LH secretion. Leptin, an adipose tissue hormone, can be decreased as well and its deficiency could be related to growth and puberty anomalies. We studied 14 asymptomatic coeliac patients in peripubertal age (7.5–13.8 years) and tested their leptin levels in order to correlate them with endocrine and anthropometric data. Before the diet was started leptinaemia (M±DS) was: 4.94 ± 5.53 ng/ml. In 10/1…
Genome-Wide Linkage Scan in a Moroccan Family With Autosomal-Recessive Exstrophy of the Bladder Identifies a Novel Susceptibility Locus on Chromosome…
2009
Purpose Exstrophy of the bladder (EB) is part of the bladder exstrophy-epispadias complex (BEEC) representing a spectrum of urogenital anomalies in which part or all of the distal urinary tract fail to close and are exposed on the outer abdominal wall. Familial occurrence is rare and previous studies are suggestive of an underlying multifactorial mode of inheritance. However, no causally related genetic or non-genetic factor has been identified so far. In this study, we aim to identify potential risk/modifying loci that might contribute to EB. Material and Methods A genome-wide linkage scan was performed in a consanguineous kindred of Moroccan origin where three affected males showed the sa…
Sirolimus treatment of severe PTEN hamartoma tumor syndrome: case report and in vitro studies
2013
Background: Phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome (PHTS) is caused by germ line mutations in the PTEN gene. Symptoms include cancer pre- disposition, immune deviations, and lipomas/lipomatosis. No causal standard therapy is available. We describe a therapeutic attempt with the mammalian target of rapamycin (mTOR) inhibitor sirolimus for a PHTS patient suffering from thymus hyperplasia and lipomatosis. We furthermore assessed the in vitro effects of sirolimus and other inhibitors on lipoma cells of the patient. Methods: The patient underwent clinical and blood examinations and whole-body magnetic resonance imaging to assess tumor sizes. Lipoma cells of the patient we…
Inflammatory Characteristics of Monocytes from Pediatric Patients with Tuberous Sclerosis.
2015
Objective Therapeutic options for the tuberous sclerosis complex (TSC) syndrome showed varying outcomes. Malfunctional tsc1 / tsc2 genes leave mTOR uninhibited, a positive downstream modulator of the innate proinflammatory immune system, which has not yet been described in pediatric patients with TSC. Methods Using polymerase chain reaction (PCR) gene expression levels of monocytes after cultivation with lipopolysaccharide (LPS) or with LPS + mTOR inhibitor rapamycin, patients with TSC ( n = 16) were compared with healthy subjects ( n = 20). Results Compared with monocytes from healthy controls, LPS showed a more prominent gene expression pattern in patients with TSC (CCL24, CXCL10, IL…
Congenital Hepatic Fibrosis
2005
The disease presentation of autosomal recessive polycystic kidney disease (OMIM #263200, ARPKD) is highly variable and includes polycystic kidneys, pulmonary hypoplasia, and congenital hepatic fibrosis. The authors report an unusual case of ARPKD presenting with hepatosplenomegaly and cytopenia mimicking acute leukemia.
CHARACTERIZATION OF CHRONIC HEPATITIS B IN CHILDHOOD USING MOLECULAR BIOLOGY TECHNIQUES
1992
The introduction of molecular biology techniques in the diagnostics of chronic hepatitis B virus infection proved HBV DNA to be the most sensitive marker of viral replication and infectivity. The aim of our study was to characterize the HBV DNA status in children with chronic hepatitis B with various molecular biology techniques in relation to conventional HBV markers. Methods: 206 sera of 172 and liver tissue of 108 children with chronic hepatitis B infection were investigated by dot blot-, Southern blot-, and in situ hybridization. In dot blot and Southern blot negative specimens polymerase chain reaction (PCR) was performed. Results: 111 of the 206 sera were positive for HBV DNA by dot b…

Nasal continuous positive airway pressure (NCPAP) devices using variable (vf-) and continuous (cf-) flow or synchronized nasal intermittent positive pressure ventilation (s-NIPPV) are used to prevent or treat intermittent hypoxia (IH) in preterm infants. Results concerning which is most effective vary. We aimed to investigate the effect of s-NIPPV and vf-NCPAP compared to cf-NCPAP on the rate of IH episodes. Preterm infants with a gestational age of 24.9–29.7 weeks presenting with IH while being treated with cf-NCPAP were monitored for eight hours, then randomized to eight hours of treatment with vf-NCPAP or s-NIPPV. Data from 16 infants were analyzed. Due to an unexpectedly low sample size…
Iron deficiency risk factors in infants at one year: A cross-sectional study
1985
A cross-sectional study was performed to assess the relative importance of well-known risk factors for iron deficiency in one-year-old children and to detect new ones. Serum ferritin, erythrocyte protoporphyrin and haemoglobin were used as diagnostic tools to screen for iron deficiency. Epidemiologic analysis of data included measures of association, potential impact and a log-linear model to obtain adjusted measures. Socioeconomic variables show a strong association with iron deficiency (low income, odds ratio = 5.07, UCL = 16.08, LCL = 1.60; unemployed father, odds ratio = 4.16, UCL = 14.94, LCL = 1.16; emigration, odds ratio = 9.14, UCL = 54.56, LCL = 1.53). Some errors in feeding practi…
Congenital emphysematous lung disease associated with a novel Filamin A mutation. Case report and literature review
2019
Abstract Background Progressive lung involvement in Filamin A (FLNA)-related cerebral periventricular nodular heterotopia (PVNH) has been reported in a limited number of cases. Case presentation We report a new pathogenic FLNA gene variant (c.7391_7403del; p.Val2464Alafs*5) in a male infant who developed progressive lung disease with emphysematous lesions and interstitial involvement. Following lobar resection, chronic respiratory failure ensued necessitating continuous mechanical ventilation and tracheostomy. Cerebral periventricular nodular heterotopia was also present. Conclusions We report a novel variant of the FLNA gene, associated with a severe lung disorder and PNVH. The lung disord…
