Tinker Toy test performance is presented for a normative group of 5- to 12-year-old children. Contrary to reported findings for some executive function tasks, developmental trends in Tinker Toy Test performance were not found. Results from a large group (N=55) of children who had sustained traumatic brain injury demonstrated that Tinker Toy Test performance was sensitive to the effects of traumatic brain injury and significantly associated with separate clinical ratings of functional or executive impairment. Present findings support the utility of the Tinker Toy Test as one component of the pediatric neuropsychological evaluation following traumatic brain injury.

Drug-sensitivity of 99 isolates of coccidia from broiler farms.

Coccidia were isolated from 99 broiler farms in 12 broiler-producing states and tested for sensitivity to contemporary anticoccidial drugs. The isolates usually comprised two or more species, including 92 Eimeria acervulina, 47 E. maxima, 28 E. tenella, and 10 E. brunetti. Based on intestinal-lesion-score reduction of 30% or more, 38% of isolates were resistant to monensin (110 ppm), 29% to salinomycin (60 ppm), 20% to nicarbazin (125 ppm), and 46% to amprolium + ethopabate (125 + 4 ppm). Isolates with 50% or greater reduction of lesion scores were considered sensitive. Thirty-three percent were sensitive to monensin, 53% to salinomycin, 67% to nicarbazin, and 39% to amprolium + ethopabate. Other isolates had intermediate response to drugs and were considered to have "reduced sensitivity." There was some evidence for incomplete cross resistance to the polyether, ionophorous products.

Childhood drowning: review of the literature and clinical implications.

In children the risk of submersion is highest in those under 5 years of age and in male adolescents 15-19 years of age. This review examines the research literature that identifies factors related to drownings and near drownings, strategies to prevent these occurrences, and suggestions for primary prevention and associated nursing interventions.

A survey of Coccidia on 43 poultry farms in Argentina.

Fecal samples from 43 broiler and breeder farms in the Entre Rios and Buenos Aires districts of Argentina were examined for Coccidia. Thirty-eight samples were positive by microscopic examination after salt flotation, with counts of 138 to 415,800 oocysts per gram of feces. Samples were aerated for 2 days and inoculated into 21-day-old chicks for determination of prepatent period. Eimeria praecox was conclusively identified in 56% of the samples by producing typical oocysts (17 x 21 microns) in the feces by 83-90 hr postinoculation (PI). Eimeria mitis was present in 67% of the samples, producing typical oocysts (14 x 15.5 microns) before 95 hr PI. Typical oocysts of Eimeria maxima (20 x 30 microns) and/or typical lesions in the midgut upon necropsy 5-6 days PI were present in 42% of the samples. Eimeria tenella was suspected in 24 of 43 samples on the basis of oocyst size but was confirmed in six samples (14%) at necropsy of infected birds with typical lesions in the ceca (hemorrhage, coagulated blood in the lumen, and thickened cecal mucosa). Characteristic lesions of Eimeria acervulina and ovoid oocysts (14 x 18 microns) were present in all 40 positive samples (93%). Lesions in the lower small intestine of birds inoculated with two of the samples (5%) were typical of Eimeria brunetti. These results confirmed the presence of six species of Coccidia in Argentine poultry (all except Eimeria necatrix, which is known from previous reports) and demonstrated a prevalence and intensity for E. praecox and E. mitis that were previously unreported.
