A general latent class model for performance evaluation of diagnostic tests in the absence of a gold standard: an application to chagas disease.

We propose a new general Bayesian latent class model for evaluation of the performance of multiple diagnostic tests in situations in which no gold standard test exists based on a computationally intensive approach. The modeling represents an interesting and suitable alternative to models with complex structures that involve the general case of several conditionally independent diagnostic tests, covariates, and strata with different disease prevalences. The technique of stratifying the population according to different disease prevalence rates does not add further marked complexity to the modeling, but it makes the model more flexible and interpretable. To illustrate the general model proposed, we evaluate the performance of six diagnostic screening tests for Chagas disease considering some epidemiological variables. Serology at the time of donation (negative, positive, inconclusive) was considered as a factor of stratification in the model. The general model with stratification of the population performed better in comparison with its concurrents without stratification. The group formed by the testing laboratory Biomanguinhos FIOCRUZ-kit (c-ELISA and rec-ELISA) is the best option in the confirmation process by presenting false-negative rate of 0.0002% from the serial scheme. We are 100% sure that the donor is healthy when these two tests have negative results and he is chagasic when they have positive results.

[Moderate and severe sudden deafness treated with low-energy laser irradiation combined with auricular acupoint sticking].

To test the therapeutic effect on moderate and severe sudden deafness treated with low-energy laser irradiation on acupoint and external auditory canal combined with auricular point sticking (APS) and as compared with electroacupuncture.Two hundred and fifty-eight cases of moderate and severe sudden hearing loss were randomly divided into an observation group 1, an observation group 2 and a control group, 86 cases in each group. In three groups, 10% low molecular Dextran 500 mL were used for intravenous infusion. Based on the above treatment, the observation group 1 was treated with low-energy laser irradiation on acupoint and external auditory canal (such as Ermen (TE 21), Tinggong (SI 19) and Tinghui (GB 2)), combined with APS at Gan (liver), Shen (kidney) and Neifenmi (endorine), etc. The observation group 2 was treated with electroacupuncture at the same acupoints as those point irradiation in observation group 1. Fifteen days made one session. The therapeutic effects were evaluated after one and two sessions.After two sessions, The cured rate was 40.7% (35/86) in observation group 1 and 38.4% (33/86) in observation group 2,which were superior to 25.6% (22/86) in control group (both P < 0.05). Compared with one session, the therapeutic effects after two sessions were better in two observation groups (both P < 0.05), but there was no significant difference between two groups (both P > 0.05). In comparison of the improvements of frequency audiometry and auditory function, the two observation groups were better than those in control group (P < 0.05, P < 0.01), and the improvements after two sessions were better in two observation groups (both P < 0.01).Both of low-energy laser irradiation on acupoint and external auditory canal combined with APS and electroacupuncture are able to decrease frequency audiometry, improve auditory function, and the therapeutic effects are better with prolongation of treatment time. The clinical efficacy of above two the rapies on moderate and severe sudden deafness is superior remarkably to that of conventional treatment. The therapy of low-energy laser irradiation on acupoint and external auditory canal combined with APS can replace the electroacupuncture therapy in treating moderate and severe sudden deafness.
