RESUMO
El 90 por ciento de los pacientes VIH-SIDA presentan lesiones bucales durante el curso de la enfermedad, observándose en la mayoría de los niños en las etapas iniciales, lesiones muchas veces no imputables al VIH. Determinar las manifestaciones bucales y su relación con el porcentaje de linfocitos CD4 y la carga viral, en 40 niños VIH/SIDA que acudieron a la consulta de infectología y odontología pediátrica de la Ciudad Hospitalaria Dr. Enrique Tejera. A través de un estudio descriptivo y de campo, se analizaron las variables, edad, género, categoría clínico-inmunológica, manifestaciones en tejidos blandos y duros, porcentaje de linfocitos CD4 y carga viral. El grupo de niños más afectado fue el de 1 a 6 años y el género femenino. La categoría clínica inmunológica más frecuente fue la B2 y la C3. En 65 por ciento hubo caries y en 80 por ciento lesión de tejidos blandos. La lesión bucal más común fue: adenopatías 57.5 por ciento, seguida de candidiasis 30 por ciento, y en igual proporción (17,5 por ciento) afta-úlceras y gingivitis; parotiditis y xerostomía 12.5 por ciento, herpes oral y petequias 10 por ciento, queilitis 7.5 por ciento, leucoplasia vellosa y eritema gingival lineal 2.5 por ciento. Independientemente del porcentaje de CD4 y carga viral, se evidenciaron manifestaciones bucales en tejidos duros y blandos, en una frecuencia relativamente alta, de allí la imperiosa necesidad de institucionalizar los programas de atención odontológica, así como la instrucción, sensibilización y motivación a los padres, representantes y personal de salud en el área pediátrica, sobre la importancia de la salud bucal en los niños VIH/SIDA.
90 percent of the childrens infected with VIH-AIDS may be at increased risk of experiencing oral lesions during the course of the illness, principally at the initial stage, the most of these lesions were not associated to HIV. To determine the oral manifestations and their relation with the percentage of lymphocytes CD4 and the viral load, in 40 children being treated for HIV-infection of the Paediatric Infection and Dentistry Service at the Ciudad Hospitalaria Dr. Enrique Tejera.. By means of a descriptive study of field, the variables age, gender, immunological clinical category, soft and hard tissue manifestations, percentage of lymphocytes CD4, and viral load were analyzed. The childrens more affected were the group of 1 to 6 years old and in feminine gender. The most frequent immunological clinical category was the B2 and the C3. In 65 percent there was dental caries, and in 80 percent soft oral lesion. The most common oral manifestation was adenopaty 57,5 percent, followed of candidacies 30 percent, and in equal proportion 17.5 percent aphthous ulcerations, and gingival erythema, parotid en largement and xerostomia 12,5 percent, herpes oral and petechiae 10 percent, cheilitis 7,5 percent, hairy leukoplakia and gingival erythema linear 2.5 percent. Independently of percentage CD4 and the viral load, oral manifestations on hard tissue were recorded as much as in soft tissue. The hard and soft weave injuries were relatively high, consequently, the urgent necessity to institutionalize preventive and therapeutic dental program, and also the education, sensibilization and motivation to parents, representatives and health personnel in the paediatric area; about the importance of oral health in HIV/AIDS children.

The prevalence rates and household distribution of seroreactivity to Trypanosoma cruzi by complement fixation (CF) and indirect immunofluorescent antibody methods were determined in a population of 1,087 persons living in a rural area endemic for Chagas' disease in northeast Brazil. There was a gradual rise in the rate of seropositivity to 60% by age 20. Between ages 20 and 55 the prevalence rate remained at about 60%, but declined thereafter. The decline in the older age groups was not accompanied by a fall in geometric mean titer, suggesting that the decline might better be explained by an increased mortality among those seropositive than by a decrease in CF reactivity associated with age. There was variation in the rates of seropositivity in children among the geographic subunits, but the rates among adults were fairly uniform. Household clustering of seropositivity was demonstrated when both household size and age distribution were taken into account. The presence of a seropositive child less than 5 years of age was a good indicator of a household with a high rate of seropositivity; screening for young seropositive children might be a useful tool to locate high risk households. Seropositive children in households where the mother was seropositive but the father seronegative were significantly younger than seropositive children in households where the father was seropositive but the mother seronegative even though the age distribution and the overall rate of seropositivity in both groups of children were similar; thus, conversion to seropositivity earlier in life in children of seropositive mothers may not be due solely to increased exposure, but may indicate that the immunologic response in such children differed from that of children from seronegative mothers.
