Osteomielitis crónica con periostitis proliferativa

Chronic osteomyelitis with proliferative periostitis is a kind of osteomyelitis that is characterized by a great periosteal reaction resulting of low grade stimulation, usually a caries lesion associated a periapical pathology. It affects especially children and young adults, with the mandible as the most common site, usually in the inferior aspect. Clinically presents as a painless hard swelling intra and/or extra-oral. Radiographic aspects include bone layers new formed, parallel to each other and to the underlying cortical surface, giving the characteristic appearance of "onion skin". Treatment includes elimination of the cause, with or without antibiotics, being restored the facial symmetry of patient. The present article is a clinical case report of chronic osteomyelitis with proliferative periostitis affecting a female 11 year old patient, caused by a caries lesion in the left permanent first molar, that was submissed to a exodontia and the facial symmetry of the patient was restored with management.

Ensaios terapêuticos com penicilina: IV - Bouba - (Framboesia, pian, yaws): tratamento das ulcerações gomosas, periostites, osteites áreas de rarefação óssea e gangoza (Rhinopharyngitis mutilans)

Six patients of terciary yaws, were treated with Penicillin in small dosis at Evandro Chagas Hospital of the Oswaldo Cruz Institute. The lesions presented by the patients were: gummatous ulcerations, periostitis, osteitis, osteoporosis and gangoza (rhinopharyngitis mutilans). In all cases, clinic recovery were obtained, the time of treatment varying from 2 to 8 months. The total amount of oxford units 'per" subject varied from 48.000 to 586.800 Patients with bone lesions, ever after the treatment, has not showed complete recomposition of the bone structure, ever so aparently healing and with negative sorologics tests. Identical results has been observed in patient showing the same lesions and treated with neo-arsphenamine. The patients are still under observations at the Hospital.

Pathoecology and paleodiet in Postclassic: Historic Maya from northern coastal Belize

This paper examines the synergism among diet, disease, and ecology at two related coastal Maya sites in Belize (Marco Gonzalez and San Pedro) for the Postclassic and Historic periods (1350-1650 AD), which immediately follow the Classic period collapse. Stable carbon- and nitrogen-isotope ratios in collagen and stable carbon-isotope ratios in structural carbonate were analysed for bones from 65 humans and a wide variety of faunal species. There are no apparent differences in whole diets or degree of carnivory between individuals with lesions indicative of anemia and those without, but those with lesions appear to have consumed significantly more C4 foods and protein from lower trophic levels. Non-specific infection (periostitis) and vitamin C deficiency (scurvy) are also present in high frequencies and appear to co-occur with lesions indicative of anemia, particularly in childhood. Individuals with scurvy also appear to have consumed significantly more C4 foods than normal individuals. Spondyloarthropathy is common in adults. These findings are discussed in light of: (1) the debate on how anemia versus scurvy are manifest and diagnosed, (2) Spanish ethnohistoric descriptions of the poor state of Maya health at the time of contact, and (3) the Osteological Paradox. We suggest that although this coastal environment exacerbated morbidity because of possible parasitic infection, the inhabitants were probably able to survive physiological stresses better than either their inland contemporaries or their modern counterparts.

Paleopathology of the commoners at Tell Amarna, Egypt, Akhenaten's capital city

The Egyptian Pharaoh Akhenaten initiated worship of a single god and established a new capital city (Tell Amarna) that was built and occupied only once from 1350-1330 BCE. This single short occupation offers a unique opportunity to study a short time period. The royal tombs have long been known and studied, but the location of graves for the common inhabitants has been an archaeological puzzle for more than 50 years. Recently four cemeteries have been located and the analysis of commingled bones from the South Tombs cemetery is presented here. The remains yield the following demographic profile: 53 adults with 19 females and 18 males; 14 juveniles between the ages of 5 and 17; and 3 infants. Arthritis and degenerative joint disease of the spine and joints indicates that DJD was not excessive. Only 2 to 8% of the adult population exhibits arthritis. There are 3 healed fractures of the arm (2 to 8% of the adult sample). There is 1 healed compressed fracture of the skull suggesting violence. The adult infection rate is between 2 and 8% with 3 healed and 1 active case of periostitis and no severe infections. Anemia is implicated by 23% of adult frontals exhibiting cribra orbitalia. Life for the common residents of Amarna appears to not have been as good as initially postulated.

The girl from the Church of the Sacrament: a case of congenital syphilis in XVIII century Lisbon

Syphilis is a sexually or congenitally transmitted infectious disease with an impact on the health of human populations that has undergone important cycles in different countries and periods of history. Its presence was first diagnosed in Europe in the late XIV century. In Portugal, although there are various written records of the infection in the last centuries, there are rare references to it in archeological findings (mummified bodies are also rare in Portugal). The current study describes a probable case of congenital syphilis in an 18-month-old girl buried in the Church of the Sacrament in Lisbon. Her body, dating to the XVIII century, was found mummified together with dozens of others, still not studied. Symmetrical periostitis of the long bones, osteitis, metaphyseal lesions, left knee articular, and epiphyseal destruction, and a rarefied lesion with a radiological appearance compatible with Wimberger's sign all point to a diagnosis of congenital syphilis. The diagnosis of this severe form of the infection, possibly related to the cause of death in this upper-class girl, calls attention to the disease's presence in XVIII century Lisbon and is consistent with the intense mobilization at the time in relation to the risks posed by so-called heredosyphilis. It is the first case of congenital syphilis in a child reported in archeological findings in Portugal, and can be correlated with other cases in skeletons of adults buried in cemeteries in Lisbon (in the XVI to XVIII centuries) and Coimbra (XIX century). Finally, this finding highlights the need to study the entire series of mummified bodies in the Church of the Sacrament in order to compare the paleopathological findings and existing historical documents on syphilis, so as to expand the paleoepidemiological knowledge of this infection in XVIII century Lisbon.

"Cara inchada" of cattle, an infectious, apparently soil antibiotics-dependant periodontitis in Brazil

The objective of this review on the investigation of "cara inchada" in cattle (CI), pursued over the last 30 years, was to elucidate the pathogenicity of the disease and come to proper conclusions on its etiology. CI has been widely considered to be of nutritional origin, caused primarily by mineral deficiency or imbalance. However, the disease consists of a rapidly progressive periodontitis, affecting the periodontal tissues at the level of the premolars and molars during the period of tooth eruption generally starting in young calves. The disease led to great economic losses for farmers in central-western Brazil, after the occupation of new land for cattle raising in the 1960s and 1970s. The lateral enlargement of the maxillary bones of affected calves gave the disease the popular name of "cara inchada", i.e., swollen or enlarged face. The enlargement was found to be due to a chronic ossifying periostitis resulting from the purulent alveolitis of CI. Black-pigmented non-saccharolytic Bacteroides melaninogenicus, always together with Actinomyces (Corynebacterium) pyogenes, were isolated in large numbers from the periodontal lesions. B. melaninogenicus could be isolated in small numbers also from the marginal gingiva of a few healthy calves maintained on CI-free farms. "In vitro"-assays showed that streptomycin and actinomycin, as well as the supernatants of cultivates of actinomycetes from soils of CI-prone farms, applied in subinhibitory concentrations to the bacteria tested, enhanced significantly (up to 10 times) the adherence of the black-pigmented B.melaninogenicus to epithelial cells of the bovine gingiva. The antibiotics are apparently produced in large quantities by the increased number of soil actinomycetes, including the genus Streptomyces, that develop when soil microflora are modified by cultivating virgin forest or "Cerrado" (tree-savanna) for the first time for cattle grazing. The epidemiology of CI now provides strong evidence that the ingestion with the forage of such antibiotics could possibly be an important determinant factor for the onset and development of this infectious periodontitis. The antibiotic enhanced adherence of B.melaninogenicus to the sulcus-epithelium of the marginal gingiva, is thought to allow it to colonize, form a plaque and become pathogenic. There is experimental evidence that this determinant factor for the development of the periodontitis is present also in the milk of the mothers of CI-diseased calves. It has been shown that the bacteria isolated from the periodontal CI-lesions produce enzymes and endotoxins capable of destroying the periodontal tissues. The epidemiology of CI, with its decline in incidence and its disappearance after several years, could be explained by the fact that the former equilibrium of the microflora of the once undisturbed virgin soil has been reached again and that the number of antibiotic producing actinomycetes has been anew reduced. By this reasoning and all the data available, CI should be considered as a multifactorial infectious disease, caused primarily by the anaerobic black-pigmented non-saccharolytic Bacteroides melaninogenicus, always together with the micro-anaerobic Actinomyces pyogenes. Accordingly, the onset and development of the infectious periodontitis is apparently determined by ingestion with the forage of subinhibitory concentrations of antibiotics produced in recently cultivated virgin soils. This hypothesis is supported by the recent observation of renewed outbreaks of CI-periodontitis in former CI-prone areas, following fresh cultivation after many years. The infectious nature of CI is confirmed by trials in which virginiamycin was used efficiently for the oral treatment of CI-diseased cattle. Previously it has been shown, that spiramycin and virginiamycin, used as additives in mineral supplements, prevented CI-periodontitis.

Nutrition et état de santé : études paléochimique et paléopathologique de la population exhumée du cimetière protestant Saint-Matthew, ville de Québec, Canada (1771-1860)

Quatre-vingt-quinze squelettes humains issus des fouilles archéologiques du cimetière protestant Saint-Matthew (ville de Québec, 1771-1860) ont été étudiés en associant deux aspects de la paléonutrition : la paléochimie et la paléopathologie. Le but de cette recherche est d’explorer la relation entre nutrition et état de santé pour cette population préindustrielle. Des informations directes sur l’alimentation ont été recueillies par l’analyse des isotopes stables du carbone et de l’azote du collagène des os, et des informations indirectes ont été obtenues par une quantification de l’état de santé des individus. Les méthodes paléopathologiques utilisées sont celles de l’« indice de santé » (Steckel et al., 2002) pour la comparaison interpopulationnelle, puis des méthodes comprenant des degrés de sévérité plus précis afin d’étudier les variations intrapopulationnelles. L’analyse de ces données atteste d’un état de santé relativement mauvais par comparaison avec d’autres groupes nord-américains contemporains, malgré une alimentation similaire. Des différences alimentaires ont été observées en fonction des données paléodémographiques (âge, sexe), mettant notamment en évidence une variabilité temporelle dans la réalisation du processus de sevrage. De plus, un régime alimentaire moins riche en ressources C4 (maïs, sucre de canne) et en ressources animales (viande, poissons, produits laitiers) a été constaté pour les enfants entre 2 et 7 ans par rapport aux individus plus vieux. Enfin, une relation possible entre la sévérité de certaines pathologies (cribra orbitalia et périostite) et la consommation des ressources alimentaires en C4 et/ou marines et riches en protéines a été observée.

Manejo da dor inguinal crônica pós-hernioplastia (inguinodinia)

A dor inguinal crônica pós-herniorrafia é uma situação preocupante, pois aproximadamente 10% dos pacientes submetidos à hernioplastia inguinal apresenta os sintomas, que com frequência limita a capacidade física. A etiopatogênese está relacionada a uma periostite do púbis (dor somática) e mais frequentemente à lesão nervosa (dor neuropática). É importante distinguir clinicamente entre os dois tipos de dor, pois o tratamento pode ser diferente. O médico deve estabelecer uma rotina diagnóstica e de tratamento, sendo que a maior parte dos pacientes necessitarão de terapêutica cirúrgica. A prevenção desta condição é de grande importância e pode levar a uma menor incidência da síndrome. Algumas medidas são fundamentais, como evitar pontos ou clipes no periósteo do púbis, usar criteriosamente as próteses e identificar os nervos da região inguinal. Esta última medida é certamente a mais importante na prevenção da dor crônica e implica em conhecimento profundo da anatomia e o uso de uma técnica aprimorada.

Cara inchada of cattle, an infectious, apparently soil antibiotics-dependant periodontitis in Brazil

O objetivo desta revisão das pesquisas sobre a cara inchada dos bovinos (CI), realizadas no decorrer dos últimos 30 anos, é de elucidar melhor a sua etiologia. A CI geralmente tem sido considerada de origem nutricional, causada primariamente por deficiência ou desequilíbrio mineral. A doença caracteriza-se por uma periodontite rapidamente progressiva, que afeta os tecidos peridentários a nível dos premolares e molares no período de erupção dos dentes e que se inicia geralmente em bezerros jovens. A doença causou grandes perdas econômicas aos pecuaristas da Região Centro-Oeste do Brasil, nas décadas de 1960 e 1970, com a ocupação de novas terras para criação de gado. O freqüente abaulamento lateral dos ossos maxilares nos bezerros, que deu à doença o nome popular de cara inchada, foi demonstrado ser conseqüente à periostite crônica ossificante resultante da alveolite purulenta da CI. Das lesões peridentárias foi isolado, em grande número, Bacteroides melaninogenicus, sempre junto com Actinomyces (Corynebacterium) pyogenes. Bactérias classificadas como pertencentes ao grupo sacarolí-tico e não-sacarolítico dos pigmentados de negro Bacteroides melaninogenicus e Bacteroides spp também foram isoladas, em pequeno número, de bovinos jovens sadios de fazendas CI-negativas. Ensaios in vitro mostraram que os antibióticos estreptomicina e actinomicina, bem como os sobrenadantes de cultivos de actinomicetos do solo de fazendas CI-positivas, aplicadas nas bactérias ensaiadas em concentrações subinibidoras, aumentaram significativamente (até 10 vezes) a aderência de B.melaninogenicus a células epiteliais da gengiva bovina. Esses antibióticos são produzidos no solo em conseqüência de um aumento do número de actinomicetos, incluindo os do gênero Streptomyces, quando há modificação de sua microbiota em áreas previamente ocupadas por mata virgem ou vegetação natural de Cerrado, que foram cultivadas pela primeira vez na formação de pastagem para o gado. em face da epidemiologia da CI, há fortes evidências de que a ingestão desses antibióticos pelos bovinos, junto com a forrageira, seja importante fator desencadeante para o desenvolvimento da periodontite. Através do aumento da aderência de B. melaninogenicus ao epitélio da gengiva marginal, em face da ingestão dos antibióticos pelos animais, as bactérias conseguem colonizar, formar a placa bacteriana e tornar-se patogênicas. Há evidência de que o fator desencadeante (aparentemente, os antibióticos) esteja também presente no leite de vacas-mães de bezerros afetados pela CI. Foi demonstrado que as bactérias envolvidas na periodontite produzem enzimas e endotoxinas capazes de ação destrutiva sobre os tecidos peridentários. A epidemiologia da CI, com a diminuição de sua incidência e o seu desaparecimento no decorrer dos anos, pode ser explicada pelo fato de que o prévio equílibrio da microbiota no solo virgem foi alcançado novamente e a produção dos antibióticos se reduziu. Desta maneira, a CI deve ser considerada como uma periodontite infecciosa multifatorial, causada sobretudo por bactérias anaeróbias pertencentes ao grupo Bacteroides melaninogenicus e, ao que tudo indica, desencadeada pela ingestão contínua, com a forrageira, de concentrações subinibidoras de antibióticos de solos recentememente cultivados. Esta hipótese é reforçada pela observação recente de novos surtos de CI, em áreas anteriormente positivas para a doença, em conseqüência da reforma de pastagens e capineiras após muitos anos. A natureza infecciosa da CI-periodontite foi confirmada através de experimento, em que virginiamicina mostrou-se eficaz no tratamento oral de bovinos afetados pela doença. Os antibióticos espiramicina e virginiamicina, usados como aditivos em suplementos minerais no campo, mostraram-se eficientes na prevenção da CI.

NONSPECIFIC INFECTIOUS DISEASES IN PREHISTORIC SAN PEDRO DE ATACAMA, NORTHERN CHILE

The region of San Pedro de Atacama, Northern Chile, has undergone several cultural and social changes after humans settled in Atacama Desert around 500 BC. The Atacameno people experienced the highest degree of social and cultural changes between 400 and 900 AD when they were assimilated into the Tiwanaku trade and political web that influenced most of the Central-Southern Andes. Under the influence of Tiwanaku, San Pedro de Atacama experienced its greatest economic development. Prior analyses of local human skeletal remains have shown a significant increase in the stature of the local population during the same period. In this paper, we investigate the impact of the Tiwanaku influence on the local epidemiological profile using the incidence of periostitis and osteomyelitis as indicators of biological stress. Surprisingly, the best epidemiological condition occurred during the final phase of influence of Tiwanaku (910-960 AD), and not during the apex influence (480-920 AD), as expected by the archaeological context. We suggest that population growth and aggregation may have counteracted the benefits of improved nutrition during the peak Tiwanaku influence. A severe drought occurred between 1,100 and 1,400 AD in Northern Chile. This could also explain the marked increase of bone infections in the post-Tiwanaku period (920-1,240 AD).

Pulse or hyaline ring granuloma. Review of the literature on etiopathogenesis of oral and extraoral lesions

Since the late 1950s, reports on an unusual giant-cell granulomatous lesion affecting the jaws, lungs, stomach and intestines have been published. Histopathologically, the lesions showed the presence of structureless hyaline rings with multinucleated giant cells. The aim of this review was to summarize the literature on the etiopathogenesis of the so-called oral and extraoral pulse or hyaline ring granuloma. Literature was searched using PubMed and Medline. In addition, hand search was performed. Search words were oral and extraoral hyaline ring granuloma, giant-cell hyaline angiopathy, pulse granuloma and chronic periostitis. Numerous terms for hyaline ring granuloma have been introduced over time (1971-2008). One hundred seventy-three cases of oral hyaline ring granuloma have been retrieved from the literature. In the mandible, 72.3% occurred . Two theories for etiopathogenesis have been proposed: (1) the origin of the hyaline rings is due to a foreign material (pulse and legumes) having penetrated the oral mucosa or gastrointestinal tract and lungs (exogenous theory) and (2) the rings are due to hyaline degenerative changes in walls of blood vessels (endogenous theory). Experimental production of oral and extraoral hyaline ring granulomas is consistent with the exogenous origin. Particles or remains of leguminous cells having been implanted or aspirated into human tissues whether located to the oral cavity or throughout the entire digestive tract and respiratory system are thought to be causative. Pulse or hyaline ring granulomas are rare but are well-defined oral and extraoral lesions due to implantation of the cellulose moiety of plant foods in contrast to the starch components.
