In response to the need for formal psychosocial assessment in childhood epilepsy, a 25-question inventory was constructed from raw items based on multidisciplinary inputs and tested for practicality, and psychometric attributes. Weighted inter-rater and test-retest reliability estimates were 61.8% and 63.9% respectively. A measure of concurrent validity was satisfactory though a modest discrepancy was observed between two raters (P = 0.019 and 0.0064). Discriminant validity was very satisfactory (average P 0.001) based on compared means of ratings from two groups of subjects with disparate prognosis. The inventory should be useful in the assessment of similar chronic childhood disabilities but interpretations of data should be in a wider clinical context including inputs of informant and school authorities as indicated. 相似文献

We have explored the polymorphism of the glycophorin system in the human erythrocyte membrane using the immunoblotting techniques and examining 52 individuals selected without prior bias as to their serologic state and ten documented serologic variants of M, N, S, s blood group system. Polyclonal antisera to alpha glycophorin and to alpha glycophorin CNBr carboxyl terminal fragment C (residues 82-131) and M and N specific monoclonal antibodies (MoAbs) were used. The first two reagents detect specific regions of the alpha glycophorin molecule and all electrophoretically resolved species of glycophorins immunologically related to alpha and delta glycophorins (delta glycophorin, [alpha-delta] hybrids and other glycophorins with an alteration in the carboxyl terminal segment); the M and N MoAbs identified the glycophorin species containing or lacking the M or N determinant in the amino terminal octapeptide structures. We find that immunoblotting confirmed in all cases the serologically determined phenotype; we also find that polymorphic forms of the glycophorin system are relatively infrequent; immunoblotting, independent from serologic testing, was capable of detecting five mutants, two most likely S-s-U-phenotypes; a new glycophorin species was detected in normal red cells with both antiglycophorin and antipeptide C sera, which is not evident with MoAbs; immunoblots of known glycophorin variants (En(a-), U-, Mg, Mi I, II, III, V, and Sta) confirmed but also extended our knowledge of the abnormal glycophorins involved; and the He+ and Wrb(-) cells showed normal patterns. 相似文献

A hypothyroid, 72-year-old woman with idiopathic hypopituitarism manifested severe hyponatremia, plasma hypoosmolality, and inappropriately elevated urine osmolality suggestive of a syndrome of inappropriate antidiuretic hormone secretions. The hyponatremia did not respond to demeclocycline hydrochloride, and antidiuretic hormone (ADH) levels measured by a specific radioimmunoassay were appropriately suppressed. Subsequent replacement therapy with levothyroxine sodium resulted in correction of the hyponatremia. Thus, both direct assay as well as hormone blockade failed to show an action of ADH in mediating the water retention. 相似文献

The serum of EH reacted with all red cells (RBCs) except her own, ficin- or trypsin-treated red cells, and En(a-) red cells. This reactivity defined an anti-EnaTS specificity. The red cells of the proposita typed as M-N+S-S+, Vw+Mur-Hil-Hut-Anek-Lane-, Wr(a-b+), EnaKT+. Red cells of five relatives were Vw+ and positive with her serum. Titration studies suggest that EH is genetically an MiI homozygote and that her Vw+ relatives are MiI heterozygotes. There is no history of consanguinity. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting studies have agreed with the serologic observations. A variant sialoglycoprotein of faster mobility than normal glycoprotein A, but no normal glycoprotein A, was detected on her red cells. Treatment with N-glycanase did not alter the mobility, which indicated that there was no N-glycosylation of residue 26. These findings are in agreement with the reported properties of the Mi.I-specific glycoprotein A. The relatives' Vw+ red cells showed the variant sialoglycoprotein and normal glycoprotein A. EH appears to be the first reported MiI homozygote. 相似文献

The discovery and eventual introduction of anti-microbial agents to clinical medicine was one of the greatest medical triumphs of the twentieth century that revolutionized the treatment of bacterial diseases. However, the gradual emergence of populations of antibiotic-resistant bacteria resulting from use, misuse and outright abuse of antibiotics has today become a major public health problem of global proportions. This review paper examines the origins and molecular epidemiology of resistance genes, global picture of antibacterial resistance, factors that favour its spread, strategies for its control, problems of control and the consequences of failure to contain antibiotic resistance in bacteria. 相似文献
