Blood samples from native Indians in the Kararao village (Kayapo), were analysed using serological and molecular methods to characterize infection and analyse transmission of HTLV-II. Specific reactivity was observed in 3/26 individuals, of which two samples were from a mother and child. RFLP analysis of the pX and env regions confirmed HTLV-II infection. Nucleotide sequence of the 5' LTR segme...

Periodontitis is a widespread disease that appears to be due to a specific bacterial infection. Several species of bacteria have been investigated as potential pathogens, and particularly strong evidence links the presence of Porphyromonas gingivalis with indicators of periodontitis. Information concerning the transmission of P. gingivalis between human contacts may be important in determining ...

THE PURPOSE of this report is to describe how persons having rheumatoid arthritis differ from unaffected controls in their recall of early parent+hild relations. The hypotheses examined in this study were mainly derived from research presented in several major reviews [l-3], as well as from case reports [4-61. Cross-reference to research articles shows that findings specifically describing pare...

Using the hypertriglyceridemic recall group of the Princeton School Family Study, we assessed the effectiveness and ramifications of family sampling based on hypertriglyceridemic probands and examined whether within-family correlations of lipids and lipoproteins outlast the period of shared common household environments. Thirty-two pediatric and 35 adult probands (who had fasting plasma triglyc...

Hypohidrotic (anhidrotic) ectodermal dysplasia (HED) is a congenital syndrome characterized by sparse hair, oligodontia, and reduced sweating. It is estimated to affect at least one in 17000 people worldwide. We report a rare case of HED in a 14-year-old male child patient which extraorally manifested as alopecia, scanty eyebrow and eye lashes, frontal bossing, depressed nasal bridge, and full ...

Three sibs with Cohen syndrome are presented. Abnormalities present in all three children include mental retardation, hypotonia, and short philtrum with open mouth and prominent lips. The older two sibs have a similar facies and an engaging personality. The youngest child shows a different facial appearance and marked behavioural problems, thereby illustrating the intrafamilial variability whic...
