Corneal Aberrations in Former Preterm Infants: Results From The Wiesbaden Prematurity Study

2017

Purpose To compare corneal aberrations in former preterm infants to that of full-term infants. Methods A prospective cross-sectional study was carried out measuring the corneal shape with Scheimpflug imaging in former preterm infants of gestational age (GA) ≤32 weeks and full-term infants with GA ≥37 weeks now being aged between 4 to 10 years. The main outcome measures were corneal aberrations including astigmatism (Zernike: Z2-2; Z22), coma (Z3-1; Z31), trefoil (Z3-3; Z33), spherical aberration (Z40) and root-mean square of higher-order aberrations (RMS HOA). Multivariable analysis was performed to assess independent associations of gestational age groups and of retinopathy of prematurity …

Neonatal liver abscesses associated with candidemia: three cases and review of literature.

2014

Abstract BACKGROUND: Our aim was to identify risk factors for the development of neonatal Candida liver abscess and to find useful information to better manage this potentially fatal complication. METHODS: A computerized search was conducted using PubMed. Overall, three articles describing the history of seven infants were finally considered. The characteristics of these seven cases were analyzed together with those of three new cases that we treated in the recent past. RESULTS: All the neonates were premature. Previous antibiotic use was reported in all the cases, umbilical venous catheterization in 9/10 and total parenteral nutrition in 8/10. Candida albicans was isolated in 9/10. All the…

Auditory event-related potentials at preschool age in children born very preterm.

2014

Abstract Objective To assess auditory event-related potentials at preschool age in children born very preterm (VP, 27.4±1.9 gestational weeks, n =70) with a high risk of cognitive dysfunction. Methods We used an oddball paradigm consisting of a standard tone randomly replaced by one of three infrequent deviants (differing in frequency, sound direction or duration). Results The P1 and N2 latencies were inversely correlated to age (50–63months) both in VP ( r =−0.451, p r =−0.305, p= 0.01, respectively) and term born controls (TC; n =15). VP children had smaller P1 than near-term ( n =12) or TC (1.70±0.17μV vs 2.68±0.41 and 2.92±0.43, respectively; p Conclusions Our data suggest a fast matura…

Implications for Estrogens in Parkinson's Disease: An Epidemiological Approach

2007

Abstract: Evidence from experimental and epidemiological studies suggests a role of sex hormones in the pathogenic process leading to neurodegenerative diseases, (i.e., Alzheimer's and Parkinson's disease). The effects of sexual steroid hormones are complex and vary with the events of women's fertile life. Estrogens are supposed to influence dopamine synthesis, metabolism, and transport; however, there is no consensus regarding the direction, locus, and mechanism of the effect of estrogens on the dopaminergic system. A neuroprotective effect of estrogens has been demonstrated in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-animal models of Parkinson's disease (PD). Epidemiological st…

[Contraception in chronically ill adolescents].

2003

Contraception in chronically ill adolescents has to consider side effects with regard to metabolic or hematological disease. Additionally the compliance of the patient has to be taken in account when consulting about contraceptives. In juvenile diabetics with good glycemic control and metabolic diseases of the amino acids oral contraceptives are justifiable. Adolescents with galactose-mia mostly suffer from premature ovarian failure and therefore have to be controlled wether they need contraception at all. Young women with sickle-cell anemia are at risk of thrombophilia. They should not be given hormonal contraceptives. In v. Willebrand-Jurgens-Syndrome oral contraceptives are favourable be…

A premature infant with Costello syndrome due to a rare G13C HRAS mutation.

2009

Costello syndrome is caused by mutations in the HRAS proto-oncogene whose clinical features in the first year of life include fetal and neonatal macrosomia with subsequent growth impairment due to severe feeding difficulties. We report on a premature male with Costello syndrome due to a rare G13C HRAS mutation and describe his clinical features and evolution during the first year of life. The diagnosis of Costello syndrome may be difficult at birth, especially in very preterm infants in whom feeding difficulties, reduced subcutaneous adipose tissue and failure to thrive are also part of their typical presentation.

Repair of complete bilateral cleft lip with severely protruding premaxilla performing a premaxillary setback and vomerine ostectomy in one stage surg…

2015

Background: The authors present a technique for selected cases of CBCL. The primary repair of the CBCL with a severely protruding premaxilla in one stage surgery is very difficult, essentially because a good muscular apposition is difficult, forcing synchronously to do a premaxillary setback to facilitate subsequent bilateral lip repair and, thus, achieving satisfactory results. We achieve this by a reductive ostectomy on the vomero- premaxillary suture. Material and Methods: 4 patients with CBCL and severely protruding premaxilla underwent premaxillary setback by vomerine ostectomy at the same time of lip repair in the past 24 months. The extent of premaxillary setback varied between 9 and…

Echinostoma caproni: kinetics of IgM, IgA and IgG subclasses in the serum and intestine of experimentally infected rats and mice.

2007

The kinetics of specific immunoglobulin M, A and IgG subclasses against Echinostoma caproni (Trematoda: Echinostomatidae) were analyzed in serum and intestinal fluid of two host species (Wistar rats and ICR mice) in which the course of the infection markedly differs. In rats, the worms were rapidly expelled, whereas E. caproni evokes in mice long-lasting infection. The pattern of antibody responses in both serum and intestinal samples was different in each host species. Serum responses in mice were characterized by significant increases of IgM, IgA, total IgG, IgG1 and IgG3, but not IgG2a. In contrast, serum responses in rats showed elevated levels of IgM, probably in relation to thymus-ind…

Preterm Resuscitation With Low Oxygen Causes Less Oxidative Stress, Inflammation, and Chronic Lung Disease

2009

OBJECTIVE: The goal was to reduce adverse pulmonary adverse outcomes, oxidative stress, and inflammation in neonates of 24 to 28 weeks of gestation initially resuscitated with fractions of inspired oxygen of 30% or 90%. METHODS: Randomized assignment to receive 30% (N = 37) or 90% (N = 41) oxygen was performed. Targeted oxygen saturation values were 75% at 5 minutes and 85% at 10 minutes. Blood oxidized glutathione (GSSG)/reduced glutathione ratio and urinary o-tyrosine, 8-oxo-dihydroxyguanosine, and isoprostane levels, isofuran elimination, and plasma interleukin 8 and tumor necrosis factor α levels were determined. RESULTS: The low-oxygen group needed fewer days of oxygen supplementation …
