Assessment of Leishmaniasis notification system in Santiago del Estero, Argentina, 1990-1993.

Using a capture-recapture method, this study evaluates the completeness of the cutaneous leishmaniasis (CL) surveillance system in four districts of Santiago del Estero province, Argentina, for the period 1990-1993. Four reporting sources were evaluated: medical records kept by health facilities, interviews conducted during a case-control study, and the national and provincial levels of the leishmaniasis surveillance system (LSS). Using the capture-recapture method it was estimated that 210 cases (95% confidence interval [CI]: 202-218) of CL occurred in the four districts during the study period. Completeness of reporting to the leishmaniasis surveillance system at the national level was estimated to be 44.8% (95% CI: 43.2-46.4). The study results indicate that there is substantial underreporting within the LSS, although it did show the appropriate secular trends. The reasons for under-reporting and methods for addressing this problem are discussed.

[Validity of the notifications of red measles based on clinical diagnosis in Cataluna, Spain].

OBJECTIVE: To compare the characteristics of clinical cases of measles with confirmed cases of measles registered in Cataluña during a period of four months. PATIENTS AND METHODS: An epidemiological survey was carried out on 171 cases of measles detected by a specific system of surveillance. The survey included data on age, sex, clinical symptoms, laboratory confirmation, immunization status and probable site of transmission. The relationship between the variable case (with or without laboratory confirmation) and the rest of variables was determined by the adjusted odds ratio, using a model of logistic regression. RESULTS: The epidemiological survey showed that 30.4% (52/171) had laboratory confirmation, 12.9% (22/171) had epidemiological confirmation and the rest, 56.7% (97/171) only complied with the clinical definition. The rash had a longer duration in confirmed cases (5.9 days) than in non confirmed cases (5.2 days). The lack of laboratory confirmation was associated with age younger than 5 years (ORa = 0.1; 95% CI 0.1-0.8), but there were no differences in sex, immunization status or others clinical symptoms. CONCLUSION: In clinical cases of measles the duration of the rash was lower than confirmed cases. The proportion of cases with laboratory confirmation was low (30.4%) and should be increased in the future. History of previous immunization ought not to rule out diagnosis of measles.
