An Alternative Method to Treat Ankyloglossia.

Ankyloglossia entails short lingual frenum, impairing satisfactory tongue movement and leading to problems related to deglutition, feeding and diction. This clinical report uses laser technology, rather than traditional surgical procedure with scalpel, to perform a lingual frenulotomy on a 9-year old child diagnosed with ankyloglossia, aiming to investigate more conservative and less traumatic dental procedures. Due to the many advantages of the laser device, such as bloodless surgical field, absence of sutures, minimal swelling and post-surgical pain, the high intensity diode laser is a viable alternative technique in soft tissue surgeries.

[Primary intra-osseous carcinoma]. / Carcinoma primario intraóseo.

Primary intra-osseous carcinoma (PIOC) is a rare tumor, defined as squamous cell carcinoma that develops in the jaw bones, having no initial connection to adjacent skin or mucosa. It is locally aggressive, with metastases to regional lymph nodes, (28% of cases) and lung (5% of cases) at the time of diagnosis. Its origin may be di novo or from other odontogenic tumors. The maxillary bones have epithelial tissues; therefore this neoplasm is located exclusively on this site, predominantly in the jaw. PIOC diagnostic criteria are strict and include: squamous cell carcinoma histopathology, lack of commitment and sinus mucosa, ruling out the possibility of metastasis from a distant site with a thorough clinical study and complementary methods. The treatment is, whenever possible, oncologic resection, additional radio and / or chemotherapy. Reconstructive surgery with graft and / or prostheses for aesthetic and functional are also required. We report the case of a 72 years old man who consulted for sore jaw three months after molar extraction. Curettage biopsy was performed and then resected mandible with lymphadenectomy. Histopathological examination showed a poorly differentiated squamous cell carcinoma, infiltrating jawbone with morphological findings linking him to residual odontogenic cyst and metastatic lymph nodes in 15 of 48 isolates. Postoperative radiotherapy was performed, he died at 30 months of diagnosis by progressive deterioration.

Ecomorphological diversification of squamates in the Cretaceous.

Squamates (lizards and snakes) are highly successful modern vertebrates, with over 10 000 species. Squamates have a long history, dating back to at least 240 million years ago (Ma), and showing increasing species richness in the Late Cretaceous (84 Ma) and Early Palaeogene (66-55 Ma). We confirm that the major expansion of dietary functional morphology happened before these diversifications, in the mid-Cretaceous, 110-90 Ma. Until that time, squamates had relatively uniform tooth types, which then diversified substantially and ecomorphospace expanded to modern levels. This coincides with the Cretaceous Terrestrial Revolution, when angiosperms began to take over terrestrial ecosystems, providing new roles for plant-eating and pollinating insects, which were, in turn, new sources of food for herbivorous and insectivorous squamates. There was also an early Late Cretaceous (95-90 Ma) rise in jaw size disparity, driven by the diversification of marine squamates, particularly early mosasaurs. These events established modern levels of squamate feeding ecomorphology before the major steps in species diversification, confirming decoupling of diversity and disparity. In fact, squamate feeding ecomorphospace had been partially explored in the Late Jurassic and Early Cretaceous, and jaw innovation in Late Cretaceous squamates involved expansions at the extremes of morphospace.

Study of Pathological Changes in the Dental Follicle of Disease-Free Impacted Third Molars.

BACKGROUND: The prophylactic extraction of third molars is a common practice in dental offices, but divergent opinions are found in the literature regarding the indication of this procedure. The aim of the present study was to determine the prevalence of pathological changes associated with the pericoronal tissue of asymptomatic impacted third molars that could justify prophylactic extraction. MATERIALS AND METHODS: A cross-sectional observational study was conducted in which 109 pericoronal tissues with no radiographic evidence of pathology were histopathologically analyzed. The specimens were fixed in 10% formalin, embedded in paraffin, stained with hematoxylin and eosin and analyzed individually by two pathologists. RESULT: The frequency of inflammatory infiltrate in the dental follicle of patients older than 20 years of age was significantly higher than that of younger patients (p = 0.004), demonstrating an association between inflammation in the dental follicle and patient age. The occurrence of squamous metaplasia was also greater in patients older than 20 years (p = 0.042), demonstrating that the prevalence of squamous metaplasia increases with age. A significant association was also found between inflammation and squamous metaplasia (p < 0.001). CONCLUSION: Pathological changes may be present in the dental follicle of impacted third molars even in the absence of clinical or radiographic signs of disease.

Climate change and environmental health in undergraduate health degrees in Latin America / Cambio climático y salud ambiental en carreras de salud de grado en Latinoamérica

ABSTRACT OBJECTIVE: Analyze the incorporation of climate change and environmental health courses in the curriculum grids of Medicine, Nursing, Nutrition and Clinical Psychology undergraduate courses in Latin American universities. METHODS: Descriptive and cross-sectional document review. Curriculum grids of the top ten Latin American universities were analyzed according to the rankings of QS Latin American University 2020, Times Higher Education World University 2020 and Academic Ranking of World Universities 2019. The presence of courses related to climate change and environmental health was sought in each curriculum grid. RESULTS: 104 of the 161 universities included in the study offered Medicine courses, 93 Nursing courses, 77 Nutrition courses and 118 Clinical Psychology courses. Most of the curriculum grids incorporated courses in public health and/or epidemiology (more than 70%); however, between 22% and 41% included courses on environmental health, and only one curriculum grid had a course on climate change in Medicine and Nursing (1%). CONCLUSIONS: Courses on climate change and environmental health have been scarcely introduced in the curriculum grids of the health field in Latin American universities. This could weaken the important role that health professionals play in providing health care to the population.

RESUMEN OBJETIVO: Analizar la incorporación de cursos de cambio climático y salud ambiental en las mallas curriculares del grado en Medicina, Enfermería, Nutrición y Psicología clínica en universidades latinoamericanas. MÉTODOS: Revisión documental de tipo descriptiva y transversal. Se analizaron las mallas curriculares de las diez primeras universidades latinoamericanas según los rankings QS Latin American University 2020, Times Higher Education World University 2020 y Academic Ranking of World Universities 2019.

Human antibody response to Aedes aegypti saliva in an urban population in Bolivia: a new biomarker of exposure to Dengue vector bites.

Aedes mosquitoes are important vectors of re-emerging diseases in developing countries, and increasing exposure to Aedes in the developed world is currently a source of concern. Given the limitations of current entomologic methods, there is a need for a new effective way for evaluating Aedes exposure. Our objective was to evaluate specific antibody responses to Aedes aegypti saliva as a biomarker for vector exposure in a dengue-endemic urban area. IgG responses to saliva were strong in young children and steadily waned with age. Specific IgG levels were significantly higher in persons living in sites with higher Ae. aegypti density, as measured by using entomologic parameters. Logistic regression showed a significant correlation between IgG to saliva and exposure level, independently of either age or sex. These results suggest that antibody responses to saliva could be used to monitor human exposure to Aedes bites.

Carcinoma primario intraóseo / Primary intra-osseous carcinoma

El carcinoma primario intraóseo (PIOC) es un tumor poco frecuente, definido como carcinoma escamoso que se desarrolla en huesos maxilares, no teniendo conexión inicial con mucosa ni piel adyacente. Es localmente agresivo, con una incidencia de metástasis en ganglios regionales del 28% y en pulmón del 5%, en el momento del diagnóstico. Su origen puede ser de novo o a partir de otros tumores odontogénicos. Los huesos maxilares son los únicos que tienen en su interior tejidos epiteliales, por lo cual esta neoplasia se localiza exclusivamente en este sitio, predominantemente en la mandíbula. Los criterios diagnósticos del PIOC incluyen: histopatología de carcinoma escamocelular, ausencia de compromiso de mucosa oral y senos paranasales, descartando metástasis de un sitio distante en base a estudios clínicos y métodos complementarios. El tratamiento de elección consiste, siempre que sea posible, en la exéresis con criterios oncológicos, y radio y/o quimioterapia adicional. Se requiere además, cirugía reconstructiva con injerto y/o prótesis con fines estéticos y funcionales. Presentamos el caso de un varón de 72 años, que consultó por molestias en maxilar inferior tres meses después de la extracción de un molar. Se efectuó biopsia por curetaje y luego se resecó el maxilar inferior con vaciamiento ganglionar. El estudio histopatológico mostró un carcinoma escamoso pobremente diferenciado, infiltrante en hueso maxilar, con hallazgos morfológicos que lo vinculaban a quiste odontogénico residual, y metástasis en 15 de 48 ganglios aislados. Se realizó radioterapia postquirúrgica, falleciendo a los 30 meses del diagnóstico por deterioro progresivo.

Surgical treatment of transmigration of mandibular canine

Introduction: The occurrence of canine impaction is not a rare phenomenon, but transmigration of the tooth across the midline is a less common event. The finding is normally asymptomatic and the etiologic factors involved in the transmigration process are still unclear. Objective: To present a clinical case of surgical treatment of a transmigrated mandibular canine. Case report: A 17-year-old male patient presented to the dental clinic to remove an unerupted canine. Clinical and radiological examinations led to the diagnosis of a transmigrated canine in the mental region. Surgical removal was the treatment of choice and further radiographs were needed to complement the clinical exam and to determine the location of the tooth precisely for the surgical procedure. Postoperative period was uneventful. Canine transmigration is a rare finding and symptoms are usually absent. Conclusion: An early detection is important to plan the treatment and mainly to avoid future complications.

Valor de la utilización de espaciadores de cemento y aloinjerto con antibiótico para reconstruir defectos óseos infectados: estudio experimental en conejos / Value of using antibiotic-loaded cement spacers and allograft to reconstruct infected bone defects: experimental study in rabbits

Introducción: El objetivo de este trabajo fue evaluar diferentes formas de tratamiento en fracturas expuestas con pérdida ósea e infectadas en conejos. Materiales y métodos: Se realizó un estudio experimental utilizando 25 conejos adultos. En todos se reprodujo una fractura expuesta mediodiafisaria de fémur en la cual se inoculó Staphylococcus aureus. Luego, en forma aleatoria, en el grupo I no se realizó tratamiento (grupo de control), en el grupo II se colocó polimetilmetacrilato con gentamicina y vancomicina en el foco de fractura asociado a antibiótico por vía sistémica, en el grupo III se colocó polimetilmetacrilato sin antibiótico en el foco de fractura asociado a antibiótico por vía sistémica, en el grupo IV se colocó aloinjerto crioconservado molido de hueso con vancomicina en el foco de fractura asociado a antibiótico por vía sistémica y, en el grupo V, se administró sólo antibiótico por vía sistémica. Se realizó la evaluación histológica de la seudomembrana formada alrededor del cemento con antibiótico y sin él. Resultados: En el grupo I se obtuvieron cinco cultivos positivos para S. aureus, en el grupo II y IV cinco cultivos negativos en cada uno, en el grupo III cuatro cultivos negativos y un cultivo positivo, y en el grupo V dos cultivos negativos y tres cultivos positivos. Los resultados de la evaluación histológica fueron similares y mostraron que la presencia de antibiótico en el cemento no alteró las características histológicas de la seudomembrana. Conclusiones: Cuando se decide hacer la reconstrucción de la fractura en un tiempo la asociación de antibiótico al injerto de hueso ayuda a prevenir la infección; si se decide realizar la reconstrucción en dos tiempos la colocación de un espaciador de polimetilmetacrilato con antibiótico en el defecto óseo es el método de elección.

Background: The purpose of this experimental study was to evaluate in rabbits different types of treatment in infected open fractures with bone loss.Methods: Twenty five adult rabbits were included in the study. A mid-diaphyseal open fracture of the femur was reproduced in all of them, and subsequently contaminated with Staphylococcus aureus. Group I was not treated (control group). In Group II, polymethylmethacrylate with gen-tamicin and vancomycin was placed in the fracture site, associated to systemic antibiotics. Group III was given polymethylmethacrylate without antibiotic in the fracture site, associated to systemic antibiotics. Group IV received fresh frozen morselized allograft with vancomycin in the fracture site, associated to systemic antibiotics. Group V only received systemic antibiotics. The pseudomembrane formed around the cement was histologically evaluated.Results: In Group I, five cultures were positive for Staphylococcus aureus. In Groups II and IV, all cultures were negative. In Group III, four cultures were negative and one was positive. In Group V, two were negative and three were positive. The histological results were similar in the groups in which cement had been used; this showed that the addition of antibiotics to the cement does not alter the histological characteristics of the pseudomembrane.Conclusions: For primary open fracture reconstruction, the addition of antibiotics to the bone graft helps prevent infection; and if staged reconstruction is prioritized, placing a polymethylmethacrylate spacer with antibiotics in the defect during the first stage should be considered.

Estudo comparativo in vitro de quatro materiais odontológicos utilizados em retro-obturação apical / Comparative in vitro study of four dental materials used in retrograde apical filling

OBJETIVO: Esta pesquisa objetivou avaliar a capacidade de vedamento apical de quatro materiais odontológicos utilizados em retro-obturações. MATERIAL E MÉTODO: 80 dentes humanos (caninos superiores) foram tratados endodonticamente, apicectomizados e retrocavitados, seguindo-se criteriosamente os mesmos procedimentos técnicos; a amostra foi dividida aleatoriamente em quatro grupos (n = 20); em cada grupo a retro-obturação foi realizada utilizando-se um dos seguintes materiais: cianoacrilato de etila (CE); amálgama de Prata sem Zinco (AM); cimento de ionômero de vidro modificado por resina (CIVr); cimento de ionômero de vidro modificado por resina associado a fotopolimerização do material (CIVr+foto). Os espécimes foram imersos em azul de metileno a 0,2% por 24 horas a 37°C e seccionados longitudinalmente. A análise dos níveis de infiltração do corante foi realizada através da visualização das regiões vestibular e palatina/lingual das raízes dentárias. RESULTADOS: Os resultados foram submetidos à análise de variância SANES. A infiltração marginal foi menor no G2 (CE) seguida por G4 (CIVr+foto), G3 (CIVr) e G1 (AM), o qual apresentou o maior nível de infiltração. CONCLUSÃO: Nas condições do presente trabalho, o CIVr+foto e o CE apresentaram as melhores condições de vedamento apical.

OBJECTIVE: The objective of this study was to evaluate the apical sealing ability of four dental materials used in retrograde fillings. MATERIAL AND METHOD: Eighty human maxillary canines were selected and treated endodontically; the apical ends were sectioned and root-end cavities were prepared. The sample was randomly divided in four groups of 20 specimens each. In each group, root-end cavities were filled with one of the following materials: ethyl cyanoacrylate (EC); silver amalgam not containing zinc (AM); resin-modified glass ionomer cement (GIC); or resin-modified glass-ionomer cement and light curing (GIC+light). The specimens were immersed and kept in 0.2% methylene blue for 24 hours at 37oC and then sectioned longitudinally. The analysis of dye penetration was conducted by means of visual inspection of the buccal and lingual sections of the roots. RESULTS: Analysis of variance was used to compare results. The least marginal leakage was found in the EC group, followed by the GIC+light, GIC and AM groups, which had the greatest leakage. CONCLUSION: Apical sealing with GIC+light and EC provided the best apical sealing.

Comparison of systemic and mucosal delivery of 2 canarypox virus vaccines expressing either HIV-1 genes or the gene for rabies virus G protein.

BACKGROUND: Since the primary routes of human immunodeficiency type 1 (HIV-1) infection are across mucosal barriers, a randomized trial of canarypox virus-based vectors was conducted in 84 individuals, with delivery of vaccine by mucosal routes, and was accompanied by a detailed analysis of humoral, cellular, and mucosal immune responses. METHODS: Over the course of 6 months, HIV-1-specific (vCP 205) and rabies (vCP 65) canarypox virus vectors were delivered systemically and/or mucosally into the nose, mouth, vagina, or rectum in a 4-dose schedule, followed by 2 doses of HIV-1 MN recombinant glycoprotein (rgp) 120 or subunit rabies vaccine administered by the intramuscular route. RESULTS: Administration of vaccine and collection of samples were well tolerated. Serum IgG HIV-1-specific antibodies to rgp120 were rarely seen after either systemic or mucosal delivery of canarypox virus vaccine. In contrast, serum IgG rabies and canarypox antibodies were detected in all individuals after systemic, but rarely after mucosal, delivery of vaccine. Suggestions of mucosal recognition of HIV-1 antigen included a cytotoxic T lymphocyte response in 4 of 8 individuals after administration of vaccine by the intrarectal route and a limited immunoglobulin A response at the same site. CONCLUSIONS: Each of the routes of vaccine administration was feasible in the context of a phase 1 study with motivated individuals. However, with the doses and routes of administration used, canarypox virus was not an effective mucosal immunogen.

Avaliação dos testes empregados para detecção de perfurações em luvas cirúrgicas / Evaluation of the tests used for detection of perforations in surgical gloves

A integridade das luvas cirúrgicas durante procedimentos de Cirurgia Bucal pode sofrer avarias. Dentro desse contexto, a reutilização das mesmas, seja para procedimentos invasivos ou não invasivos, prática ainda usada em alguns setores de saúde, que alegam ganho financeiro devido a poucos recursos disponíveis, é um risco desnecessário para o profissional e para o paciente. Assim, esse estudo teve como objetivo avaliar a eficiênciados testes de inspeção visual, auditiva e tátil, bem como variações dessas técnicas, empregados na detecçãode perfurações em luvas cirúrgicas. Quarenta pares de luvas cirúrgicas receberam perfurações com diferentesmateriais pérfuro-cortantes e foram submetidos a diferentes testes para avaliar a eficiência dos mesmos na detecção das perfurações. Os resultados mostram que os testes comumente utilizados para verificação de perfurações em luvas cirúrgicas, não são capazes de detectar todas as perfurações. Os achados demonstramque está totalmente contra-indicada a reutilização de luvas, sendo um risco desnecessário para o profissional e o paciente.

The integrity of the surgical gloves during procedures of Oral Surgery can suffer damages. Inside of this context, reuse of same for invasive or not invasive procedures, practice used in some health sectors who makeuse of it justify such practice through financial benefits an unnecessary risk both to the professional and the patient.Thus, this study aimed to evaluate the effectiveness of the visual, auditory and tactile, as well as variations of these techniques, inspection tests used in thedetection of perforations in surgical gloves. Forty pairs of surgical gloves have holes with different perforationsmaterials and were subjected to various tests to assess the efficiency of them in detection of holes. The results show that the tests commonly used about to verification of perforations in surgical gloves, are not capable of detectingall the perforations. The finds demonstrate that is fully not indicated the reuse of gloves, being an unnecessary risk about to the professional and the patient.
