    Notes: Abstract A toxicological assessment of water quality conditions (30 physical-chemical parameters and a screening of organic pollutants by reverse-phase HPLC) was performed in Algeciras Bay, Cadiz, Spain in relation to problems in six floating ponds for gilthead (Sparus auratus) growth. The study was completed with a short-termArtemia toxicity test, and the measurement of heavy metal concentrations in molluscs from different sites of the Bay. Cadmium, lead, and cyanide at sublethal toxic concentrations were found in most of the analyzed samples, and very high concentrations of ammonia, phenols, nitrites, cyanide, and sulphide were found in some sampling sites. In addition, seven water samples showed toxicity onArtemia. The problems in the floating ponds (low growth rates, high mortality, and infectious diseases) can be related, in part, to the very bad water quality conditions.

    Notes: Abstract Eighteen children with severe head injuries and diffuse brain swelling were studied. They were separated into two groups based on the computed tomography (CT) findings. Seven patients had small ventricles in the normal location and small or absent cisterns. Eleven had these signs plus small deep-seated intraparenchymal hemorrhagic foci and/or intraventricular hemorrhage. Patients in the first group were in relatively good neurological condition; their intracranial pressure was easily controlled and all had a favourable outcome. On contrast, children in the second group had a more severe clinical presentation, frequently had uncontrollable intracranial hypertension, and more than 50% died.

    Notes: Abstract Over a period of 5 years, 25 children between 1 day and 26 months of age were prospectively evaluated because of the presence of meningomyeloceles. Cranial sonography was used to ascertain the types of associated cranial alterations. Twenty-three children (92%) presented signs of Chiari II malformation. In only two (8%) were the ultrasonographic results normal. The abnormalities detected were classified as alterations of the ventricular system, extraventricular alterations, and associated findings. The most frequent alteration of the ventricular system was the “batwing” configuration of the frontal horns, which appeared in 22 children (88%). Among the extraventricular alterations, 23 children (92%) had a downward displaced cerebellum, obliterated basal cisterns and low positioning of the tentorium cerebelli. Associated findings were a polymicrogyria in 1 case and intracranial hemorrhage in 2. The 23 children with Chiari II malformation were followed up clinically and sonographically. Our findings were similar to those of other published series. In spite of the introduction of magnetic resonance imaging, we consider cranial sonography to be an inexpensive and convenient method of evaluating the existence of Chiari II malformation in the child with meningomyelocele and of following up its evolution after shunt procedures.
