Resumen La bacteriemia es una presentación atípica de la infección por Campylobacter jejuni, y es más frecuente en pacientes con inmunodepresión avanzada debido al VIH u otras enfermedades sistémicas. Debido a la terapia anti-retroviral, en las últimas décadas el número de casos ha disminuido. Presentamos el caso de una mujer en situación de calle, con VIH en etapa C3, que cursó con una bacteriemia por C. jejuni durante su hospitalización por una tuberculosis pulmonar. Realizamos una breve revisión de bacteriemia por C. jejuni en pacientes con VIH.
Bacteremia is an atypical presentation of Campylobacter jejuni infection and it is more frequent in patients with advanced inmunodepression due to HIV or other sistemic diseases. Because of the highly active antiretroviral therapy, in the last decades the number of cases had declined. We report a case of a homeless woman with HIV in C3 stage who was diagnosed with the bacteremia during her hospitalization for pulmonary tuberculosis, and a brief review of C. jejuni bacteremia in HIV patients.

ABSTRACT The Vernet, Collet-Sicard and Villaret Syndromes are uncommon; they affect the spaces through which some of the cranial nerves pass and can lead to the impairment of motor functions of the tongue. The etiology is variable, including benign or malignant tumors, metastasis, infections, or Idiopathic causes. Patients with the disease may report changes in the mobility and function of the tongue, dysphonia, dysarthria and dysphagia. The purpose of this article was present a case report of Collet-Sicard syndrome, and to highlight the importance of proper diagnosis by dentists. Appropriate treatment must be instituted as soon as possible and the patient should be treated by a multidisciplinary team until the complete remission of symptoms.
RESUMO As síndromes de Vernet, Collet-Sicard e Villaret são pouco frequentes que acometem os espaços por onde passam alguns dos pares de nervos cranianos que podem ocasionar o comprometimento das funções motoras da língua. A etiologia dessas patologias podem ser oriundas de tumores benignos ou malignos, metástases, infecções, ou serem consideradas Idiopáticas. Pacientes que apresentam a doença, podem relatar alterações de mobilidade e função da língua, disfonia, disfagia e disartria. O objetivo deste artigo é relatar um caso sobre a síndrome de Collet-Sicard, ratificando a importância do cirurgião-dentista no diagnóstico de doenças que se manifestam na cavidade oral. O tratamento adequado deve ser instituído o mais rápido possível e o paciente deve ser acompanhado por uma equipe multiprofissional para possibilitar a remissão completa dos sintomas.
ABSTRACT
The composition of the essential oil obtained by hydrodistillation from Dalea strobilacea Barneby (Fabaceae) aerial parts was examined by GC and GC/MS. beta-Phellandrene (44 percent) together with alpha-pinene (18 percent) were the main essential oil components. Antimicrobial activity of the essential oil was evaluated against eight bacterial strains. A moderate growth inhibition of Klebsiella pneumoniae, Staphylococcus aureus and Enterococcus faecalis was shown by the essential oil.

Acantholippia deserticola (Phil.ex F. Phil.) Moldenke is a Verbenaceae that has long been used in traditional medicine in Tarapacá (Chile) as an analgesic, anti-inflammatory and aphrodisiac agent. Sincé alpha - and beta -thujone were identified as the main constituents (88.4 percent) of the essential oil from this plant, we investigated its biological properties. The results show that the essential oil from Acantholippia deserticola decreased locomotive and rearing activity compared to control group rats, including those treated with diazepam, but the essential oil had no effects on head movements or grooming. The essential oil also had significant anxiolytic and antidepressant effects. This essential oil, therefore, has sedative, anxiolytic and antidepressant actions on the rat central nervous system.
Acantholippia deserticola es una Verbenaceae de uso en la medicina tradicional como analgésico, antiinflamatorio y afrodisíaco en la región de Tarapacá, Chile. En el aceite esencial se ha identificado alfa - and beta -tuyonas como principales constituyentes (88.4 por ciento) de esta planta, que ha llevado a investigar sus propiedades biológicas. Los resultados muestran que el aceite esencial de Acantholippia deserticola disminuye la locomoción y el levantamiento en dos patas, en comparación con el grupo control, incluido el tratado por el diazepam, pero el aceite esencial no tuvo efecto sobre la sacudida de cabeza y el acicalamiento. En ambas pruebas, se observa un efecto significativo del aceite esencial en los efectos ansiolíticos y antidepresivos, lo que indica que el aceite esencial tiene actividad sedante, ansiolítica y antidepresiva en el sistema nervioso central.

Nowadays, Diabetic Neuropathy (DN) is considered the most common cause of peripheral neuropathy in clinical practice. It can affect sensitive, motor or autonomic nerve fibers, with symmetric, asymmetric, acute or chronic presentations. Due to this variability, with multiple physiopathologic mechanisms involved, a complex clinical classification has been used until recently. The aim of this review is to present a new classification of diabetic neuropathy, based on its physiopathology. It is divided in metabolic microvascular and hypoxic, autoimmune and inflammatory, compressive, secondary to complications ofdiabetes and related to treatment. It must be understood that DN is notjust a functional disease, but a complication of diabetes with molecular and pathological substrates caused by hyperglycemia. Therefore, normalization of blood glucose is a fundamental step towards the successful prevention and treatment of DN.

Fundamento: los cambios en la función normal de la vía aérea durante el proceso activo de crecimiento facial pueden tener una influencia significativa en el desarrollo facial. Objetivo: presentar la utilidad de la evaluación de la vía aérea mediante tomografía computarizada de haz de cono. Método: se revisaron las imágenes de 250 mujeres y 128 hombres a través del programa Sidexis para Galileos. La selección de las zonas a medir se determinó mediante las coordenadas que pasan por el conducto nasopalatino en el plano sagital y por la zona interproximal de los incisivos centrales superiores, en el plano coronal. Resultados: se observó una correlación negativa moderada pero estadísticamente significativa entre la edad del paciente y el área de la vía aérea en ambos sexos. Se encontró una correlación positiva moderada, estadísticamente significativa entre la longitud del velo del paladar y la edad en los dos sexos. Se presentó también una correlación del área de sección transversal y la longitud del paladar blando. Conclusiones: la Tomografía Computarizada de Haz de Cono proporciona una imagen tridimensional confiable de la relación espacial entre los dientes y la cara y sus estructuras anatómicas circundantes permitiendo una evaluación adecuada de los tejidos.
Background: changes in the normal function of the airway during the active process of facial growth can have a significant influence on facial development. Objective: to present the usefulness of the evaluation of airway Beam Computed Tomography Cone. Methods: images of 250 women and 128 men using the program Sidexis to Galilee were reviewed. The selection of areas to be measured was determined by the coordinates that pass through the canal in the sagittal plane nasopalatine and interproximal area of the upper central incisors in the coronal plane. Results:a moderate negative correlation, but statistically significant between patient age and area of the airway in both sexes was found. There was a moderate positive correlation, statistically significant between the length of the soft palate and age in both sexes. A correlation of cross-sectional area and length of the soft palate was also showed. Conclusions: the Beam Computed Tomography Cone provides a reliable three-dimensional image of the spatial relationship between the teeth and face and surrounding anatomical structures allowing adequate assessment of the tissues.
ABSTRACT
Cisto periapical é uma cavidade patológica revestidapor epitélio com um lúmen contendo líquidoe restos celulares, que tem por sua origem osrestos epiteliais de Malassez. Possui crescimentolento e assintomático, normalmente não atingindograndes dimensões. Em consequência destalesão, o paciente pode apresentar mobilidadee deslocamento dos dentes adjacentes. Nestetrabalho, os autores realizam uma breve revisãoliterária e o relato de um caso clínico de duplocisto periapical, acometendo paciente do gêneromasculino, negro, 13 anos, estudante de Olinda(PE), que apresentava um aumento de volumena hemiface esquerda. Na anamnese, referiuque o aumento de volume teve início há cercade 2 anos, mas como não havia queixa de dor oproblema foi relevado. Ao exame extra-bucal, opaciente apresentava deformidade na hemifaceesquerda com sob-elevação da asa do nariz esquerda,sem evidências de hipertermia ao toque.Ao exame intra-bucal, apresentava aumento devolume na região dos elementos 21 e 25. Radiograficamente,evidenciaram-se duas enormeslesões do tipo císticas relacionadas com o ápicedos elementos 21 e 25. O exame histopatológicoda peça operatória confirmou em definitivo odiagnóstico de cistos periapicais.
Periapical cyst is a pathological socket coatedby epithelium with liquid and cellular remainingportions lumen that has for its originthe Malassez epithelial remaining portions. Itpresents slow and assintomatic growth, normallynot reaching big dimensions. In consequenceof this injury, the patient may presentadjacent teeth mobility and displacement.In this work, the authors carry through onebrief literary revision and the history of a clinicalcase of double periapical cyst attemptinga male black patient, 13 years old, student,from Olinda (PE), that presented a volumeincrease in left hemiface. In anamnesis, hisgenitor mentioned that the volume increasehad beginning about 2 years, but as it didnot have pain complaint, they had raised theproblem. In extra-buccal examination, thepatient presented deformity in left hemifacewith under-rise of left nose wing, withouthyperthermia evidence on touch. In intrabuccalexamination, he presented volumeincrease of 21 and 25 elements region. Thex-ray examination showed two enormouscystic injuries related with 21 and 25 apex.The histopathological examination definitivelyconfirmed the periapical cysts diagnosis.

Las ecuaciones de perfil de copa pueden ser usadas para caracterizar la apertura de la copa, el perfil del área de la copa, el volumen de la copa y la porosidad de la copa de un rodal, para predecir el crecimiento en altura de los árboles individuales, el crecimiento en área basal y la probabilidad de mortalidad en modelos de desarrollo del rodal, lo cual es importante para tomar decisiones de manejo. El objetivo de este estudio es construir ecuaciones para predecir los parámetros de la copa de pino silvestre en un bosque de montaña. Han sido ensayados diferentes modelos para estimar la relación de copa, la máxima anchura de copa, la altura a la base de la copa y la altura al punto de máxima anchura de copa usando regresión no lineal. La validación de los modelos da como resultado que son adecuados para estimar el tamaño de copa de pino silvestre y la importancia que tiene su estudio en los bosques de montaña
