Ruptured ducts release the mucous that accumulates into adjacent tissues, leading to swelling. This report describes a large mucocele involving the lower lip, which was produced in a child by incorrect use of a pacifier. A few important concepts are discussed to help clinicians in the diagnosis and treatment of this pathology.

Espelelia paipana is an endangered giant caulescent rosette endemic to Boyacá department. In order to establish whether a plant disease, characterized by the loss of leaf pubescence (PPF) and attributed to the pathogenic action of endophytic microorganisms, is the cause of the increasing mortality of population, the physiological performance of the species was evaluated with and without PPF. The incidence (% leaves affected in each of the 27 individuals in the current population) and severity (% leaf area affected on 135 leaves) of the PPF were monitored over a period of nine months, in three topographic zones of different heights. During four consecutive days in both dry and wet season, physiological parameters as chlorophyll content index (ICC), stomatal conductance (Gs) and leaf temperature (Tfol) were measured in healthy and affected leaves. The study was complemented with isol...

In order to establish whether a plant disease, characterized by the loss of leaf pubescence (PPF) and attributed to the pathogenic action of endophytic microorganisms, is the cause of the increasing mortality of population, the physiological performance of the species was evaluated with and without PPF. The incidence (% leaves affected in each of the 27 individuals in the current population) and severity (% leaf area affected on 135 leaves) of the PPF were monitored over a period of nine months, in three topographic zones of different heights. During four consecutive days in both dry and wet season, physiological parameters as chlorophyll content index (ICC), stomatal conductance (Gs) and leaf temperature (Tfol) were measured in healthy and affected leaves. The study was complemented with isolations and pathogenicity tests to identify the causal agent of the PPF. Overall, although the disease incidence in E. paipana was constant over time, the severity progressed surpassing 60 % of the leaf area. The increasing of severity in the upper side of leaves was attributed to the photo-oxidative effect of high radiation between 11:00 h and 14:00 h of the day. The reduction of functional leaf area because of the PPF, led to low Gs with serious implications for carbon fixation and thus limiting growth and biomass renewal. The effect of season in Tfol varied according to the topographic zone, while the ICC did not present a defined pattern with respect to the PPF; its low values could be associated with the production of other pigments. Finally, although it is not possible to ensure that Botrytis sp. is the causative of the loss of leaf pubescence, it is postulated as the most probably causal agent due to its high representativeness in the isolates and its infectious potential during the pathogenicity tests. In general, the reduction of healthy leaf biomass and decrease of physiological performance suggest that PPF affect negatively the survival of E. paipana, which means that the use of biological controllers could be a strategy to mitigate its effect on the population

Entretanto, podem ocorrer casos em que um ou mais dentes estão presentes ao nascimento, sendo estes chamados de dentes natais (Figuras 1 e 2). Também podem ocorrer casos em que um ou mais dentes erupcionam na cavidade bucal no período compreendido entre o nascimento até um mês de idade, sendo conhecidos como dentes neonatais. Várias denominações têm sido empregadas para os dentes natais. Termos como dentes congênitos, fetais, pré-decíduos e precoces também têm sido descritos (1) .

Grazing and agriculture have transformed at least 30% of the Guantiva-La Rusia region, turning continuous extensions of high Andean forest in a fragmented landscape, and P cuadrijuga remnants have become smaller and more isolated. The aim of this study was to establish the environmental differences between a matrix of grazing pastures and the interior of fragments, to evaluate the physiological responses of P cuadrijuga and determining the edge effect. Air temperature and humidity, soil water holding capacity and photosynthetic active radiation, were measured along two 50X2m transects from the matrix toward the center of fragment. Six trees inside the transects were chosen in each one of three sites (matrix, edge and interior) to measure the index chlorophyll content and to sample leaves to assess ...

Twelve sound second lower primary molars were fractured in buccolingual directions for SEM examination. The results showed that the hydroxyapatite cristals were arranged

Foliar damage can be controlled through synchronous leaf production and specialized phytochemical strategies. In this study, the dynamics of foliar damage in different cohorts of seedlings were evaluated to determine if the High-Andean species, Clusia multiflora (Clusiaceae) and Drimys granadensis (Winteraceae) appeal to the synchronous leaf production for controlling the herbivory and pathogenical damage, and to establish the possible relations between the healthy state, growth and mortality of seedlings. Since a recently-emerged seedling could not supply the physiological costs of specialized strategies, we expected the highest synchronous leaf production in the youngest individuals, and differences between cohorts in foliar damage. Four variables were measured to evaluate the health state along time, in three cohorts of seedlings: Proportion of predated leaves (P(p))...

Soil arthropods are a fundamental component of forest ecosystem, since they participate in the organic matter fragmentation, previous to decomposition. This role is more valuable in high altitude environments, where low temperatures limit the dynamics of biological processes, where the effects of pine plantations on soil arthropods are still not well-known. In a remnant of high-andean forest (Neusa - Colombia) and a pine plantation of about 50 years-old, it was evaluated the composition, richness and abundance of arthropods at surface (S), organic horizon (O) and mineral horizon (A) of soil, to establish the differences associated to the soil use transformation. It was used "Pitfall" sampling to register the movement of the epigeous fauna, and extraction by funnel Berlese for determining the fauna density from O and A horizons. The Shannon and Simps...

One of the most common problems in the Colombian mountains has been the replacement of native vegetation by pine plantations. Soil arthropods are a fundamental component of forest ecosystem, since they participate in the organic matter fragmentation, previous to decomposition. This role is more valuable in high altitude environments, where low temperatures limit the dynamics of biological processes, where the effects of pine plantations on soil arthropods are still not well-known. In a remnant of high-andean forest (Neusa -Colombia) and a pine plantation of about 50 years-old, it was evaluated the composition, richness and abundance of arthropods at surface (S), organic horizon (O) and mineral horizon (A) of soil, to establish the differences associated to the soil use transformation. It was used "Pitfall" sampling to register the movement of the epigeous fauna, and extraction by funnel Berlese for determining the fauna density from O and A horizons. The Shannon and Simpson indexes estimated the diversity at different places and horizons, and the trophic structure of the community was evaluated. Overall, there were collected 38 306 individuals from forest and 17 386 individuals from pine plantation, mainly distributed in Collembola (42.4%), Acari (27%), Diptera (17.6%) and Coleoptera (4.6%). The most important differences were given in the surface, where the mobilization in forest (86 individuals/day) almost triplicates the one in pine plantation (33 individuals/ day). The differences in composition were given in Collembola, Araneae, Hemiptera, Homoptera and Hymenoptera. The dynamics of richness and abundance along the year had significant high values in the native forest than in the pine plantation. The general trophic structure was dominated by saprophagous (75%), followed by predators (14%) and phytophagous (9%), but in two layers of the pine plantation soil (S and O) this structural pattern was not given. Based on the results, it was concluded that pine plantations affect the diversity, composition, community dynamic and trophic structure of soil arthropods. Also, some estimators of soil stability give signals that these effects are reducing the ecosystem function in the region. Rev. Biol. Trop. 58 : 1031-1048. Epub 2010 September 01.
