A statistical study of the quality of surface water intended for human consumption near Valencia (Spain).

Water quality in the European Union is subject to legislation through directives that are applicable in all Member States. The directives specify a set of physical and chemical parameters that should be regularly controlled using a network of sampling points, with sampling based on the intended use of the water. This paper presents the results of a statistical comparison of the quality of water intended for human consumption at two different locations (the Canal de Benagéber and the Canal Júcar-Turia) near the town of Valencia (Spain). These are currently the only canals that could supply Valencia and other nearby towns with drinking water. The parameters considered in this paper are the ones specified in the European directives for determining the quality of water intended for human consumption. These directives specify that the 95th percentile of the distribution of each parameter should be used to assess water quality, so accurate estimation of these percentiles was essential in this paper. We found statistically significant differences among locations in chlorides, sulfates, temperature, coloration, and manganese, but the results varied depending on the statistical tests that we used; parametric methods gave better results than nonparametric methods.

Clinical trial of an oral vestibular shield for the control of snoring.

Stock intra-oral vestibular shields of a heat malleable, semiflexible ethylene vinyl-acetate material were adapted at chairside to the mouths of 77 chronic snorers. The effectiveness of the shield in controlling snoring was assessed eight to ten weeks after fitting. 77.9 per cent of subjects benefitted from wearing the device. Of the subjects who failed to benefit nine (11.7 per cent) appeared to have nasal or naso-pharyngeal obstruction. A further five (6.5 per cent) abandoned the clinical trial due to poor self-motivation while two subjects (2.6 per cent) were unable to tolerate the shield in the mouth. The potential of the device in the management of obstructive sleep apnoea warrants further investigation.

[Biochemical, clinical and genetic analysis of various aminoacidopathies (non-ketotic hyperglycemia, maple syrup urine disease, histidinemia, tyrosinemia)].

The genetical types were classified according to the clinical findings and biochemical results in cases of 13 newborn/children suffering from various aminoacidopathies. The genetical types were: 3 neonatal and 4 infantile types were found out of 7 non-ketotic disease (MSUD) patient was infantile type with 9.1 per cent keto acid decarboxylase activity in leukocyte homogenate. Among the 3 histidinemic patients 1 was severe neonatal type and 2 cases were chronic types. The 2 treated tyrosinemic children proved to be type III. (chronic with rickets).

The effect of dust-suppressant additives on the physical properties of an irreversible hydrocolloid.

The effects of dust-suppressant additives on certain physical properties of an irreversible hydrocolloid were studied in five test specimens formulated as follows: no additives (F0); 10% Duomeen cationic surfactant in 0.5% paraffin with 0.05% zinc stearate (F1); 10% Duomeen in 0.5% paraffin with 0.10% zinc stearate (F2); 20% Duomeen in 0.5% paraffin with 0.05% zinc stearate (F3); and 20% Duomeen in 0.5% paraffin with 0.10% zinc stearate (F4). The properties tested according to ADA specifications were mixing time, setting time, compressive strength, strain in compression, and permanent deformation under fixed strain. For each property, the variances between formulations were not significantly different (Levene p less than 0.05) whereas means were significantly different for stress (ANOVA p + 0.0001; Kruskal-Wallis p = 0.0019); strain (ANOVA p = 0.0003; Kruskal-Wallis p = 0.0228); deformation (ANOVA p = 0.0166; Kruskal-Wallis p = 0.0308). For the properties stress, strain, and permanent deformation under fixed strain, the paired differences of dust suppressants were established by using Duncan's multiple range test. Duomeen, instead of zinc stearate seems to be responsible for these effects.

Dancing eyes syndrome--brainstem acoustic evoked potential approach.

Three patients with dancing eyes syndrome of childhood are reported focussing on brainstem acoustic evoked potentials (BAEPs) recorded at different phases of the disease. In the first child in the acute phase BAEPs revealed pontine disturbance, which was less severe in a following milder attack. In the second child slight BAEP abnormalities were shown in the period of remission. In the case of the third child minimal pontine abnormalities were registered by BAEPs. These electrophysiological findings, in accordance with the clinical features, suggest tegmento-pontine or pontocerebellar localisation of pathology in the dancing eyes syndrome.

Multiple sclerosis in childhood: long term katamnestic investigations.

Sixteen children with multiple sclerosis, 14 with remitting and 2 with progressive course, and their follow up for 4-16 (mean, 9 years) are reported. The disease manifested in eight children at the age of 1.5-9 years, while in the other eight at the age of 12-14 years. The cases were acute, but had a stronger inclination to remission than in adulthood. In addition to the "classical" symptoms known in adult, multiple sclerosis, papilloedema and acute increased intracranial pressure were observed in nine children. Dehydrating treatment was life saving in these cases. Opsoclonus occurred in two patients, and two children had convulsions, one of whom later developed chronic epilepsy. The CSF was pathological in all the cases. Oligoclonal gamma-globulin subfraction was found in three out of the five patients tested. Three patients died. Histological examination was carried out in two of them; it revealed severe perivenous demyelinisation due to inflammation. Cortisone treatment occasionally with azathioprine reduced the duration of exacerbations, but could not prevent renewed ones and caused severe side-effects. Multiple sclerosis is a rare but not exceptional condition in children. The differences between cases in children and adults are age-dependent.

[Tuberous sclerosis--early diagnosis and its significance in juvenile epilepsy].

Twenty-three cases of tuberous sclerosis, found in the ten years' material of the authors among 2900 epileptics between o-16 years of age, are presented. 11 patients were treated before the age of 3 years, all showing infantile spasms. The earliest, in most cases congenital extraneural signs were depigmented areas on the skin. They were absent only in one case. They allowed, together with the Westsyndrome to establish the diagnosis if tuberous sclerosis before the appearance of other characteristic symptoms. Sebaceous adenoma, generally accepted as pathognostic for tuberous sclerosis, presented itself in all 12 early cases later then the leukoderma and the epileptic fits. Tuberous sclerosis is one of the important causes of epilepsy in childhood, primarily in early childhood. In this period of life the West-syndrome is the most frequent type of epileptic manifestations of tuberous sclerosis
