ABSTRACT
Objective To explore the prognostic value of APACHE Ⅱscore in patients with Severe acute organophosphorus poi-soning .Methods 42 patients with Severe acute organophosphorus poisoning ,in which 34 cases survived ,8 cases dead ,were select-ed .The APACHE Ⅱscores of patients in first 24 h of admission were collected ,and receiver operating characteristic curves (ROC curve) were drawn .Results APACHE Ⅱ score of the 42 patients with Severe acute organophosphorus poisoning was 18 ~30 (20 .11 ± 6 .32) ,in which the survival group was(16 .10 ± 3 .12) ,the dead group was(28 .01 ± 4 .46) (P<0 .01) .With the increase of APACHE Ⅱ score ,the fatality rate gradually increased .The total area under the ROC curves of APACHE Ⅱ score for death judgment was 0 .922 ,APACHE Ⅱ score of 21 .2 was the best diagnostic point ,the sensitivity was 95% ,and specificity was 89% . Conclusion The APACHE Ⅱscore could predict severity of patients with Severe acute organophosphorus poisoning ,and APACHEⅡscore ≥21 .2 could be used as the prognosis for death of the patients .
ABSTRACT
Indirect fluorescent antibody test (IFAT) using frozen sections of Brugia malayi adult worms as antigen was employed in the diagnosis and epidemiological investigation of human filariasis. Sera were collected from 704 cases with bancroftian or malayan microfilaremia. the positive rate was 92.8-99.1%. Of 150 healthy people from non-endemic areas, only one showed a positive reaction (false positive rate 0.7%) (Table 1). This technique proved to be highly sensitive and specific for the diagnosis of filariasis and the antigen is easy to prepare. It might be used in sero-epidemiological investigation for the assessment of filariasis control.
