Título: Taurodoncia múltiple: presentación de un caso / Multiple taurodontism: report of a case
Fonte: Rev. Asoc. Odontol. Argent;95(3):229-231, jun.-jul. 2007. ilus.
Idioma: es.
Resumo: La taurodoncia es una alteración morfológica de la anatomía dental que trae como consecuencia un cambio en la forma de la pieza dentaria, usualmente en las piezas multirradiculares. Consiste en un alargamiento de la cámara pulpar a expensas de los conductos radiculares, desplazando el piso pulpar hacia apical. El diagnóstico temprano y el seguimiento radiográfico son importantes. La mayoraía de las veces es un hallazgo radiográfico, dado que a la inspección clínica las piezas dentarias suelen verse normales. Puede presentarse aislado o asociado a otras anomalías dentarias. El propósito de este artículo es presentar un caso de taurodoncia múltiple que fue también un hallazgo radiográfico en un paciente de raza negra oriundo de Senegal y comunicar la alta incidencia de esta patología en dicho país.

Título: ßS-Haplotypes in sickle cell anemia patients from Salvador, Bahia, Northeastern Brazil

Resumo: ßS-Globin haplotypes were studied in 80 (160 ßS chromosomes) sickle cell disease patients from Salvador, Brazil, a city with a large population of African origin resulting from the slave trade from Western Africa, mainly from the Bay of Benin. Hematological and hemoglobin analyses were carried out by standard methods. The ßS-haplotypes were determined by PCR and dot-blot techniques. A total of 77 (48.1 percent) chromosomes were characterized as Central African Republic (CAR) haplotype, 73 (45.6 percent) as Benin (BEN), 1 (0.63 percent) as Senegal (SEN), and 9 (5.63 percent) as atypical (Atp). Genotype was CAR/CAR in 17 (21.3 percent) patients, BEN/BEN in 17 (21.3 percent), CAR/BEN in 37 (46.3 percent), BEN/SEN in 1 (1.25 percent), BEN/Atp in 1 (1.25 percent), CAR/Atp in 6 (7.5 percent), and Atp/Atp in 1 (1.25 percent). Hemoglobin concentrations and hematocrit values did not differ among genotype groups but were significantly higher in 25 patients presenting percent fetal hemoglobin ( percentHbF) > or = 10 percent (P = 0.002 and 0.003, respectively). The median HbF concentration was 7.54 ± 4.342 percent for the CAR/CAR genotype, 9.88 ± 3.558 percent for the BEN/BEN genotype, 8.146 ± 4.631 percent for the CAR/BEN genotype, and 4.180 ± 2.250 percent for the CAR/Atp genotype (P = 0.02), although 1 CAR/CAR individual presented an HbF concentration as high as 15 percent. In view of the ethnic and geographical origin of this population, we did not expect a Hardy-Weinberg equilibrium for CAR/CAR and BEN/BEN homozygous haplotypes and a high proportion of heterozygous CAR/BEN haplotypes since the State of Bahia historically received more slaves from Western Africa than from Central Africa

Título: Immuno-epidemiology of Schistosoma mansoni infections in a recently exposed community in Senegal
Fonte: Mem. Inst. Oswaldo Cruz;90(2):271-276, Mar.-Apr. 1995.
Idioma: en.
Resumo: Schistosoma mansoni was introduced in the Senegal basin around 1988, due to man-made ecological changes. Since 1991, we investigate a recent but very intense focus, Ndombo, a village near the city of Richard Toll where the outbreak was first described. Four cohorts, each a random sample (+/- 400 subjects each) from this community, were examined and followed up after treatment, starting at 8 month intervals over a 2-year period. Each cohort is examined parasitologically (Kato-Katz), clinically, serologically (circulating antigen and antibody profiles); treated with praziquantel 40 mg/kg; followed up 6-10 weeks, one and two years after treatment; and monitored for water contact patterns and local snail densities. In the first cohort, the prevalence was 91, with a mean egg count of 663 epg. Prevalences are near 100 in all age groups, but egg counts decline strongly in adults. Antigen detection in serum and urine confirmed that the egg counts genuinely reflect variations of worm burdens, not e.g. of worm fecundity. This is surprising, as in this focus acquired immunity in adults should not have yet developed according to current hypothesis. The antigen detection assays (CAA/CCA) showed high sensitivity and quantitative power, and promising perspectives as a research tool and possibly as a method for non-invasive diagnosis and screening in urine. Epidemiological in subsequent cohorts were highly similar, although seasonal variations were observed possibly due to transmission fluctuations. Anti-AWA and anti-SEA IgE levels increased with age, while IgG4 peaked in the age-group 10 years and correlated well with egg counts.(ABSTRACT TRUNCATED AT 250 WORDS)

Título: Studies on the biology of schistosomiasis with emphasis on the Senegal river basin
Fonte: Mem. Inst. Oswaldo Cruz;96(suppl):75-78, Sept. 2001.
Idioma: en.
Projeto: European Commission. INCO-DC.
Resumo: The construction of the Diama dam on the Senegal river, the Manantali dam on the Bafing river, Mali and the ensuing ecological changes have led to a massive outbreak of Schistosoma mansoni in Northern Senegal, associated with high intensity of infections, due to intense transmission, and the creation of new foci of S. haematobium. Data on the vectorial capacity of Biomphalaria pfeifferi from Ndombo, near Richard Toll, Senegal are presented with sympatric and allopatric (Cameroon) S. mansoni. Comparisons are made on infectivity, cercarial production, chronobiology of cercarial emergence and longevity of infected snails. Recent data on the intermediate host specificity of different isolates of S. haematobium from the Lower and Middle Valley of the Senegal river basin (SRB) demonstrate the existence of at least two strains of S. haematobium. The role of Bulinus truncatus in the transmission of S. haematobium in the Lower and Middle Valleys of the SRB is reviewed. Both S. haematobium and S. mansoni are transmitted in the same foci in some areas of the SRB

Resumo: Recently, our group determined the relationship between serum CAA levels and fecal egg counts in two foci very intense Schistosoma mansoni transmission: Maniema (Zaire), an area endemic for S. mansoni since several decades, and Ndombo (Senegal), where transmission has only been established since a few years. The objetive was to study and compare age-related worm load and worm fecundity patterns in these two different endemic settings. Here, we will summarize the most important findings and conclusions of this study.
