Lorenz B - - 1999
Retinopathy of Prematurity (ROP) is a major risk for permanent visual loss in extreme prematures. In stage 3+ (zone I and II), defined as threshold disease, the risk for retinal detachment with subsequent blindness is about 50% without treatment, compared to only a few percent with laser photoablation. Visualisation and ...

BACKGROUND AND OBJECTIVE: Improvements in care of low birth weight preterm infants has led to an increased survival of this population. It is not known whether the improved care has decreased the prevalence of retinopathy of prematurity (ROP), or whether the survival of even smaller infants has increased the prevalence. ...

We report on the prenatal ultrasound and postnatal findings in an infant born to a healthy, nonconsanguineous couple. The infant had microcephaly, telecanthus, blepharophimosis, cleft palate, micrognathia, abnormally modeled ears, hypoplastic left heart, hypoplastic radii and ulnae with radial subluxation, pseudoarthrotic distal humeri, fused metacarpals, tibial bowing, unusual feet with ...

Studies have reported an association between homozygosity for a variant form of the methylenetetrahydrofolate reductase (MTHFR) gene and risk for neural tube defects. Because of MTHFR's involvement with folate metabolism and evidence that maternal use of a multivitamin with folic acid in early pregnancy reduces risk for cleft lip with ...

This research examined whether an expanding training series protracts retention for infants as it does for children and adults. In three sessions spanning an 8-day period, 3-month-olds learned to move a crib mobile by kicking. Intersession intervals were either constant (1 or 4 days) or progressively expanding (average ISI = ...

A noncontact three-dimensional measuring system (liquid crystal range finder system) is described. Three-dimensional facial surface data (more than 30,000 points) could be obtained in 1 second, and the resolution was approximately 0.4 mm. The reliability and repeatability of the results were validated with a calibrating apparatus and a highly accurate ...

BACKGROUND: Numerous studies have reported an increased risk of refractive errors in prematurely born infants, but only few have been long-term and strictly population based. METHODS: A 3.5 year ophthalmological long term follow up of 248 preterm infants was performed. The infants had been included in a previous epidemiological study ...

Autosomal dominant cerebellar ataxias are a heterogeneous group of neurodegenerative disorders that generally present in adulthood. Spinocerebellar ataxia type 2 typically presents with progressive cerebellar symptoms, slow ocular saccades, and peripheral neuropathy. The onset of symptoms is usually between 20 and 40 years. We describe an infant who presented with ...

There have been few studies done on the abnormal function of velopharyngeal muscles in unrepaired cleft palate infants. To examine and assess velopharyngeal movement before primary palatoplasty offers supposedly any valuable information for the successful operation and the restoration of excellent velopharyngeal function. We designed to investigate and analyze velopharyngeal ...

Ferguson C A - - 1998
Development of the mammalian tooth has been intensively studied as a model system for epithelial/mesenchymal interactions during organogenesis, and progress has been made in identifying key molecules involved in this signaling. We show that activin betaA is expressed in presumptive tooth-germ mesenchyme and is thus a candidate for a signaling ...
Chen H J - - 1998
Developments in modern neonatal intensive care have resulted in increased survival of very premature infants. Along with this increase in survival, there has been a concomitant increase in the frequency of retinopathy of prematurity (ROP). We investigated the relationship between the severity and the time course of ROP as well ...
Anteunis L J - - 1998
Patients with cleft lip and/or palate abnormalities are likely to suffer permanent conductive (PCHL) or sensorineural hearing loss (SNHL) due in part to the association with syndromes known to include PCHL or SNHL. The presence of otitis media, a nearly universal complication in these patients, makes identifying the hearing impaired ...

During embryonic development, the proper production of extracellular matrix molecules mediates morphogenetic processes involved in palatogenesis. In the present study, we investigated whether any differences exist in glycosaminoglycan (GAG) and collagen synthesis between palate fibroblasts from infants, with or without cleft palate, in two age ranges. Subsequently, the effects of ...

Separation of chromatids of all mitotic chromosomes, here called total premature chromatid separation (total PCS), was observed in 67 to 87.5% of repeated cultures of peripheral blood lymphocytes from two unrelated infants. Also noted was a variety of mosaic aneuploidies, especially trisomies, double trisomies, and monosomies, to be called mosaic ...

Elite sport requires high training volumes. However, little is known about the relationship between training volume and performance development. This relationship appears to have an inverted U-shape. Short-term overtraining or overreaching is probably associated with insufficient metabolic recovery, resulting in a decline in ATP levels. Systemic overtraining or staleness is ...
Shaw G M - - 1998
OBJECTIVE: We previously demonstrated a strong association between periconceptional maternal cigarette smoking, infant transforming growth factor-alpha (TGFa) genotype, and risk of orofacial clefts. Because serum folate may be decreased by cigarette smoking and because maternal periconceptional use of multivitamins containing folic acid has been associated with a reduced risk of ...

Cryptorchidism (CPT) has been suggested to be common in boys with congenital abdominal wall defects (CAWD). It has been hypothesized that the low intra-abdominal pressure in both omphalocele (OMP) and gastroschisis (GS) and brain malformations in patients with OMP contribute to the high incidence of CPT. To determine the incidence ...

The infant born with a cleft lip is faced with risk factors that threaten the development of speech-language skills. The earlier the age of identification and management of the developmental delay, the better the outcome. The attainment of the mature syllable is considered to be a critical measure of babbling ...
