The present environmental scenario of the Nador Lagoon (Morocco).

In this paper, we present a multivariate approach (waters, sediments, microfauna) concerning the environmental state of the Nador Lagoon (NE Morocco). The normal water quality parameters (salinity, pH, nutrients) of the dominant marine flows are altered by local fecal water effluents, urban discharges, sewages derived from a water treatment station, and residues originated in a slaughterhouse. The geochemical analyses carried out in surficial sediment samples show very high concentrations of all metals studied near an old iron mine and moderate contents between Nador and its treatment station. Ostracods are good bioindicators of these environmental impacts, with the presence of a highly brackish assemblage in the quieter, more confined areas or the appearance of opportunistic species under hypoxic conditions. In addition, these microcrustaceans are absent in polluted bottom sediments or areas with high hydrodynamic gradients, whereas they decrease in both density and diversity if the subaerial exposure increases.

Residual pollution load of soils impacted by the Aznalcóllar (Spain) mining spill after clean-up operations.

By comparing total concentrations of potentially toxic elements in soils affected by the Aznalcóllar mining spill with those of the adjacent unaffected soils, it can be inferred that after the sludge removal, there still exists a considerable amount of residual pollution. This exceeds the suitable levels for cultivation, especially in the case of arsenic for which total concentrations are in the range of values above which eco-toxicity is considered to be possible. Elemental distribution in the soil seems to be determined by two distinctive associations (As-Pb-Hg-Sb and Cu-Zn-Cd) with different geochemical behaviours.

[Brachmann-de-Lange syndrome in our population: clinical and epidemiological characteristics].

INTRODUCTION: We present the study of the clinical and epidemiological characteristics of Brachmann-de Lange syndrome in our population. PATIENTS AND METHODS: In this study we present the analysis of 13 cases of Brachmann-de Lange syndrome identified among 24,696 infants with congenital defects registered by the Spanish Collaborative Study of Congenital Malformations (ECEMC) between April 1976 and June 1996. RESULTS: The minimum estimation of the prevalence in our population is 0.97 per 100,000 live births. We have epidemiologically confirmed the presence of intrauterine growth retardation and have observed that parental ages tend to be relatively young. We have observed a wide range of clinical expression of this syndrome. One hundred percent of our cases have limb reduction defects, followed in frequency by craniofacial alterations (84.62%), abnormal hair distribution (76.92%) and genital defects (69.23%). Upper limbs are predominantly affected and one case of diaphragmatic hernia is worth mentioning. We underline the importance of the differential diagnosis with Fryns'syndrome. CONCLUSIONS: The cases studied correspond to the most severe form of the syndrome, reason for which the prevalence is a minimal estimate. However, the mild forms of the syndrome are more frequent and it is important to consider that the face, especially the form of the eyebrow, could be a good guide for the diagnosis of mild forms of the syndrome.

Holoprosencephaly associated with caudal dysgenesis: a clinical-epidemiological analysis.

We have studied 9 cases with the combination of some form of holoprosencephaly and any degree of caudal dysgenesis. The cases were identified through the Spanish Collaborative Study of Congenital Malformations (ECEMC). Of the 9 cases, 6 infants had an aneuploidy syndrome, one had Meckel syndrome, and 2 cases were of unknown etiology. We determined that the prevalence figure for the association of both conditions in the same child was 0.08 per 10,000 livebirths, and 18.8 times higher for stillbirths (i.e., 1.50/10,000). This prevalence is significantly higher than what would be expected by chance.

Tracheoesophageal fistula, gastrointestinal abnormalities, hypospadias, and prenatal growth deficiency.

We studied 2 sibs, born to consanguineous parents, who presented with an MCA pattern which includes low birthweight, tracheoesophageal fistula, duodenal atresia, extrahepatic biliary atresia, hypoplastic pancreas, and hypospadias. This constellation of congenital anomalies appears to be a previously unreported autosomal recessive syndrome. A computerized search of the data files of the Spanish Collaborative Study of Congenital Malformations (ECEMC) identified 3 other unrelated infants with intestinal atresias, hypospadias, and low birth weight. These cases may represent a milder expression of the same syndrome.
