Oral findings in secondary syphilis
2018
Background Syphilis is a sexually transmitted disease caused by Treponema pallidum. However, there are of hematogenic and vertical transmission. All health care professionals must be aware of the manifestations of this condition, such as oral lesions. Objectives This study to analyze and compare four clinical cases of syphilis that were diagnosed based on lesions in the oral cavity with published literature. Material and Methods Four patients with a confirmed sorologic and clinical diagnosis of syphilis were examined, confirmated from manifestation of oral lesions together with analysis of serological laboratory tests and histopathological analyses. Results Lesions were found in classic sit…
Detection of periodontal pathogens in mothers of preterm birth and/or low weight
2019
Background The present study aims to estimate the possible relationship between periodontal pathogens in the oral cavity and the birth of Preterm Birth (PTB) and/or Low Birth Weight (LBW). Material and Methods It’s a case- control study with the subgengival biofilm samples were collected from four sites up deeper until 48 hours postpartum and were processes by Polymerase Chain Reaction (PCR) for presence the periodontal pathogens Prevotella intermedia (Pi), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) e Aggregatibacter actinomycetemcomitans (Aa). The mothers were divided into case grup (babies weighing < 2500g and/or gesta…
Fluorescenzserologischer Nachweis eines in Syphilitikerseren vorkommenden Antik�rpers gegen ein hitzestabiles Antigen der Reiter-Treponemen
1967
An insgesamt 88 Syphilitikerseren wurde der FTA-Test mit erhitzten Reiter-Treponemen durchgefuhrt. 71 mal reagierte die Serumverdunnung von 1∶100, in 53 Fallen eine solche von 1∶500 positiv. Von 53 Kontrollseren waren nur 2 bei der Verdunnung von 1∶100 positiv. Hieraus wird auf das Vorkommen eines hitzestabilen gemeinsamen Gruppen-Antigens in Reiter-Treponemen und T. pallidum geschlossen. Die Zugehorigkeit dieses Antigens zu den Lipopolysacchariden wird diskutiert. Menschliche Antikorper gegen dieses Antigen sind vorerst nur fluorescenzserologisch nachzuweisen.
