treponematosis

This study analyzed skeletal health disparities among African American and Euro-American males of low socioeconomic status born between 1825 and 1877. A total of 651 skeletons from the Cobb, Hamann-Todd, and Terry anatomical collections were macroscopically examined for skeletal pathologies related to dietary deficiencies and disease. Individuals were separated into age, ancestry, birth (Antebellum, Civil War, Pre-Reconstruction, and Reconstruction), combined ancestry/birth, enslaved versus liberated, and collection cohorts...

Syphilis is a treponematosis clinically characterized by a primary lesion, a secondary rash affecting the skin and the mucous membranes and late lesions affecting cardiovascular and central nervous systems, viscera and bones. Off all the skeletal lesions, the most characteristic are those of the skull, most commonly affecting frontal and parietal bones and nasal and palatal region. The collection of 647 adult skulls of both sexes and 98 child and adolescent skulls from the "Broumov Ossuary" (13th - 18th century) was examined for the presence of the bone syphilis lesions...

Syphilis is a recurrent treponematosis of acute and chronic evolution. In general it is either sexually or congenitally transmitted. Primary syphilis appears as a single and painless lesion. Secondary syphilis may manifest years later, the secondary bacteremic stage is accompanied by generalized mucocutaneous lesions. Tertiary disease can be disseminated to bones and virtually any organ, involving principally the ascending aorta and the central nervous system. Nuclear medicine provides diagnostic methods in case of skeletal manifestations by bone scan - identifying periostitis and osteomyelitis...

The foot is particularly exposed to injury and infection in the tropical areas. This article provides a review of the main diseases affecting the foot in the tropics including leprosy, ainhum, ulceration due to Mycobacterium ulcerans, mycetoma, chromomycosis, Kaposi's sarcoma, elephantiasis, podoconiasis, dracunculosis, tungiasis, syphilis and endemic treponematosis, larva migrans, scytalidiosis, and envenomation. Prevention is essential.

The combination of high sexually transmitted infection (STI) prevalence and low HIV prevalence has been described as the Indian Ocean paradox. To investigate current epidemiology of HIV and STI in the Comoros, we conducted cross-sectional surveys of a representative sample of the adult population, and convenience samples of female sex workers and male STI patients. Only one (0.025%) of 3990 community participants was HIV-infected, while 142 (3.6%) had treponemal antibodies. Treponemal antibodies were not associated with past genital ulcers, number of sexual partners or adverse outcomes of pregnancies; their prevalence did not increase with age and there was no concordance within couples...

A historical and comparative study of the origins and emergence of syphilis and AIDS show that both result from human intrusions. Treponema probably existed in primates before human infection, and nonvenereal treponemal infection existed in prehistoric tropical Africa. When humans began wearing clothes, the disappearance of endemic infection ended immunity and led to receptivity to venereal infection. It was long thought that syphilis was first introduced in Europe by the conquistadors, but lesions typical of treponematosis dating from before the Common Era have been found in Europe...

We evaluated the prevalence of skin lesions in a gorilla population in the Republic of Congo. The observed lesions were typical of yaws, a treponematosis described in gorillas and humans living in tropical regions. Among the 377 gorillas identified, 17% presented skin lesions, mainly on their faces. The worst cases presented physical handicaps because of the deep lesions. As in humans, lesions break out when individuals are young. Lesions were more prevalent among males than females above 8 years old. This sex-bias prevalence could result from the behavioral characteristics of males through a greater exposure to wounds...

Despite major efforts to eradicate these disorders, yaws, bejel, and pinta (endemic treponematosis) remain serious health issues in many regions of the world. Aside from prominent skin manifestations, these diseases may also lead to significant osseous, neurologic, and ophthalmologic complications. Although progress has been made in differentiating the causative species in a research setting, a simple, specific, and sensitive diagnostic test remains elusive. Parenteral penicillin, in appropriate dosage, is the treatment of choice; alternative antibiotics such as tetracycline and erythromycin may also be effective...

We performed a systematic screening of HIV infection and five other sexually transmitted infections on a consecutive sample of 529 female sex workers from Niamey. HIV seroprevalence rate was 30.1%, with HIV-1 profile in 93.1% of the cases. For curable STI, 4.7% of women had treponematosis, 7% gonorrhoea, 16.8% Gardnerella vaginalis, 36.9% Mycoplasma hominis and 68.2% Chlamydia trachomatis infection. The percentage of women with at least one STI was significantly higher in HIV positive's: 95.6% against 87.9%...

Contagious mucocutaneous dermatitis is a frequently encountered disease of mountain hares (Lepidus timidus) in Finland. We describe the histopathologic changes and propose an etiologic cause for this disorder. Fifty-three cases collected during 1982-2000 were examined histologically. Transmission electron microscopy was performed in one case. In fully developed lesions, keratinocytes in epidermis and follicular infundibula were swollen and contained large eosinophilic intracytoplasmic inclusion bodies with marked reticular and ballooning degeneration...

Symmetrical exuberant periostitis is a rare disease caused by variety of infectious and non-infectious causes. Treponematosis is one of the rare causes of this condition. We report a patient who presented with left arm swelling, secondary to onion peel periostitis of the humerus, which was caused by Treponema species.

Treponema paraluiscuniculi, the etiologic agent of rabbit venereal syphilis, is morphologically indistinguishable from Treponema pallidum subsp. pallidum (T. pallidum), the human syphilis treponeme, and induces similar immune responses and histopathologic changes in the infected host. Because of their high degree of relatedness, comparative studies are likely to identify genetic determinants that contribute to pathogenesis or virulence in human syphilis. The tpr (Treponema pallidum repeat) genes are believed to code for potential virulence factors...

OBJECTIVES: This study was conducted to test several hypotheses: 1. That rheumatoid arthritis and syphilis were New World diseases, only transmitted to the Old World subsequent to the passages of Christopher Columbus; 2. To indirectly test the hypothesis that lead poisoning was prevalent in Roman Italy by looking for its byproduct, gout; 3. To test the hypothesis of compromised sanitation in ancient Italy, on the basis of spondyloarthropathy frequency; and 4. To assess variation of trauma frequencies in ancient Italy, by examining frequency of focal periosteal reaction...
