RESUMO
The goals of this study were to evaluate if hemoglobin played a role as adjuvant in experimental peritonitis in horses and could cause clinical and haematological alterations that could be used for diagnosis and prognosis of cases of peritonitis. Fifteen adult horses were randomly divided into 5 equal groups, which were injected intraperitoneally with the following suspension: GI: 1x109 colony-forming units (CFU) of E. coli diluted in 500 mL of 0.9% saline solution plus 5 g of hemoglobin; GII: 1x109 CFU of B. fragilis diluted in 500 mL of 0.9% saline plus 5 g of hemoglobin; GIII: 1x109 CFU of E. coli in combination with 1x109 CFU of B. fragilis diluted in 500 ml of 0.9% of saline plus 5 g of hemoglobin; GIV: 500 mL of 0.9% saline plus 5 g of hemoglobin and GV: 500 mL of 0.9% saline. Leukopenia with neutropenia was observed in GI and GIII and a significant increase in plasma fibrinogen concentration occurred in horses of GI. There was a significant increase in total nucleated cell count in peritoneal fluid in horses of GI, GII, GIII and GIV. Fever, tachycardia, tachypnea, abdominal wall sensibility and tension, diarrhoea, colic, and decreased borborygmi sounds were the most frequent clinical signs observed in horses of GI, GII, GIII and GIV. In conclusion, hemoglobin was able to cause chemical peritonitis in horses, it had an adjuvant effect when associated t
RESUMO
This article focuses on the AIDS mortality profile as related to socioeconomic and geographic variables, as well as evaluating the impact of deaths from AIDS in the State of Rio de Janeiro. The analysis included all death certificates for residents of the State from 1991-1995, 10,024 of which had AIDS recorded as the primary cause of death. In the 20-49-year age bracket, among individuals who had died of AIDS, the proportion of those with university schooling (14%) and the proportion of single individuals (75%) were greater than the respective proportions for all other causes of death (5.4% and 56.3%). For the population as a whole, the AIDS mortality rate increased from 1991 to 1995, from 20.6/100,000 to 30.2/100,000 for males and from 3.7/100,000 to 7.9/100,000 for females. For the year 1995 in the 20-49-year bracket, considering the 17 groups of causes from the ICD-9, AIDS was the third most common cause of death among men and the fifth most common among women. The proportion of Potential Loss of Life Years up to 65 years as a function of AIDS increased from 1991 to 1995, from 3.4% to 4.7% for men and from 1.4% to 2.9% for women. During this same period there was also an increase in the number of counties in the State of Rio de Janeiro with reported deaths from AIDS.

This study aimed to estimate and evaluate the under-recording of AIDS cases that evolved to death. From 1991 to 1995, the Mortality Information System recorded 9,213 adult deaths due to AIDS, related by name, date of birth, and date of death to 15,505 AIDS recorded by the Disease Data Registration System from 1982 to 1996. This procedure showed that 51.9% of AIDS deaths recorded in the period were not recorded as AIDS cases as they should have been. Univariate and multivariate analysis showed that women had a greater chance of under-recording than men (OR = 1.27). A lower probability of proper recording was observed in individuals with less schooling, and illiterates had a two-fold chance of not being properly recorded, as compared to individuals with college degrees. Deaths that occurred in health facilities classified as private units had a greater probability of not being recorded than those occurring elsewhere (mainly those classified as public reference units) (OR = 2.58). Deaths occurring in the city of Rio de Janeiro had a greater probability of under-recording than those in other cities (OR = 2.20).
