Postnatal management and outcome of prenatally diagnosed lung lesions

Advancements in fetal diagnostic imaging have increased prenatal diagnosis of many fetal anomalies. The purpose of this chapter is to review the etiology and natural history of prenatally diagnosed cystic lung lesions, including congenital cystic adenomatoid malformations (CCAM), pulmonary sequestrations (PSs), hybrid lesions, and bronchogenic cysts, and then discuss current concepts in the management and outcome of these lesions.

Postnatal management and outcome for fetal-diagnosed intra-cerebral cystic masses and tumours

The increasing availability and resolution of non-invasive prenatal imaging has increased our ability to diagnose accurately a wide variety of fetal anomalies. It has also resulted in the serendipitous discovery of ‘lesions’ that may have little clinical impact upon the child's subsequent development although their ability to raise parental anxiety can be great. The purpose of this review is to put the postnatal clinical relevance of some of these findings into their proper context. Copyright © 2009 John Wiley & Sons, Ltd.

Prognosis of fetuses with a cystic hygroma

This paper reports our experience with 55 fetuses identified in utero to have a cystic hygroma. The outcome of fetuses with an isolated cystic hygroma, cystic hygroma with non-immune hydrops, and cystic hygroma with multiple anomalies was evaluated. Approximately two-thirds of karyotypes were aneuploid, and a strong association of septation and aneuploidy existed. Only five cases, four of which had isolated hygromas, came to term and resulted in live births. Two of these involved small non-septated lesions which resolved in utero.

In utero sonographic diagnosis of a communicating enteric duplication cyst in a giant omphalocele

Enteric duplications are rare lesions, and relatively few cases have been diagnosed prenatally. We present, to our knowledge, the first case of an associated communicating ileal duplication cyst in a huge omphalocele diagnosed prenatally. The prenatal ultrasound findings revealed four features of the cystic lesion including peristaltic movements of the cystic wall, communication between the cyst and normal bowel lumen, intra-cystic echogenic contents, and echogenic mesenteric tissue (fat) close to the cyst. These distinct characteristics helped us to make a firm in utero diagnosis. Copyright © 2001 John Wiley & Sons, Ltd.

Aerosols and environmental pollution

The number of publications on atmospheric aerosols has dramatically increased in recent years. This review, predominantly from a European perspective, summarizes the current state of knowledge of the role played by aerosols in environmental pollution and, in addition, highlights gaps in our current knowledge. Aerosol particles are ubiquitous in the Earth’s atmosphere and are central to many environmental issues; ranging from the Earth’s radiative budget to human health. Aerosol size distribution and chemical composition are crucial parameters that determine their dynamics in the atmosphere. Sources of aerosols are both anthropogenic and natural ranging from vehicular emissions to dust resuspension. Ambient concentrations of aerosols are elevated in urban areas with lower values at rural sites. A comprehensive understanding of aerosol ambient characteristics requires a combination of measurements and modeling tools. Legislation for ambient aerosols has been introduced at national and international levels aiming to protect human health and the environment.

Leaf and fruit necroses associated with vanadium-rich ash emitted from a power plant burning fossil fuel

Necrotic brown lesions developing on leaves and fruits of lemon, and other plants, near fossil-fuel-burning power plants emitting vanadium-rich ash, were reproduced experimentally by inoculating leaves with this type of ash, which is strongly acidic. Comparable lesions were formed when drops of vanadium oxide, dissolved in NaOH, were put on leaves and fruits. Neutralizing, or adding excess H₂SO₄ (to pH 3), did not alter lesion formation. The histology of these lesions was similar to that of lesions attributed to vanadium-rich ash.

Alzheimer's disease: molecular concepts and therapeutic targets

The beta amyloid peptide is the major component of the neuritic plaques, the characteristic lesions in Alzheimer's disease. Mutations in three genes (APP, PS-1, and PS-2) cause familial Alzheimer's disease by alteration of the rate of generation of amyloid peptide or the length of this peptide. However, in the 90% non-familial cases, other factors play a major pathogenetic role. These include the apolipoprotein E genotype, the "plaque-associated" proteins promoting the formation of toxic fibrillar aggregates or the chronic inflammatory responses. The aim of this review is to explain the steps in the complex cascade leading to Alzheimer's disease and, based on this, to report the current efforts to intervene in these different pathophysiological events in order to prevent progression of Alzheimer's disease. Whereas acetylcholine substitution is currently used in clinical practice, future therapeutical strategies to combat Alzheimer's disease may include anti-inflammatory treatments, vaccination against beta amyloid peptide, or treatment with cholesterol-lowering drugs.
