Objective: The aim of this retrospective study was to evaluate the prevalence and pattern of hypodontia in the permanent dentition, including and excluding third molars, in a Portuguese sample. Patients and methods: The study group comprised 2888 patients, observed between 2005 and 2009 at the Dentistry Clinic of the Instituto Superior de Ciências de Saúde-Norte (ISCSN, Portugal). The patients were examined for evidence of hypodontia and presence or absence of deciduous teeth in those presenting agenesis. The age range varied from 7 to 21 years. In order to study the absence of the third molar, subjects under 14 years were excluded. Statistical analysis was performed using SPSS®. Results: Excluding third molars, the prevalence of tooth agenesis was 6.1% for the Portuguese population. Tooth agenesis was found more frequently in females than in males, although this difference was not statistically significant (P > .05). The most commonly missing tooth was the mandibular second premolar, followed by maxillary lateral incisor, and maxillary second premolar. There was a significantly higher prevalence of missing third molars in the agenesis group than in the nonagenesis group. There was a correlation between second premolar and upper lateral agenesis with presence of their corresponding deciduous teeth. © 2012 CEO Published by/ Éditépar Elsevier Masson SAS All rights reserved/Tous droits réservés.

To verify the eventual relationship between maxillary lateral incisor agenesis (MLIA) and one of the clinically established facial biotypes. The analysis was performed in and between 3 groups: individuals with MLIA, their relatives and a control population defined as “normal” or unaffected. Among these, a comparison between adults and growing individuals was also carried out. The dolicofacial biotype was mainly found in children with bilateral agenesis, while the unilateral agenesis as well as the control population of unaffected children showed mainly a mesofacial pattern. The braquiofacial biotype was prevalent in children without agenesis but (family) related to patients with agenesis. This is the case also for all the adults studied, even if the frequency of the braquiofacial is similar to the one attained by the mesofacial biotype when found in unaffected individuals related with agenesis patients. The notable variability found, evidenced by the high values of the standard deviations calculated for each group, makes difficult to definitely establish a positive correlation between the MLIA and one of the facial biotypes with the present data. © 2014, Universidad de la Frontera.

Introduction: The Minimal Hepatic Encephalopathy (MHE) has been associated to changes in life quality and in the aptitude to drive vehicles, to the appearance of an explicit form of Hepatic Encephalopthy and to a worst prognosis, including a high mortality risk. In this context, the early detection of this condition will lead to the reduction of its consequences. The Psychometric Hepatic Encephalopathy Score (PHES) consists in five easily applicable and scored tasks including the Trail Making Test A and B, the Digit Symbol Test, the Serial Dotting Test and the Line Drawing Test. The use of the PHES is recommended by the International Society for Hepatic Encephalopathy and Nitrogen Metabolism, for the MHE diagnosis and monitorization, as long as local translations and normative data are available. The main objective of the present study is the PHES normalization for the Portuguese Population. Subjects and Methods: The tasks that compose the PHES were applied to 115 healthy subjects from four districts of the north of Portugal. Variables like age, gender, educationyears and the profession type were study in relation to the obtained results through the use of Student́s t test and Pearsońs correlation. In order to build the normality tables the linear regression was used. Results: Age and education years were the independent variables more related to the performance on the five tasks. Conclusion: The availability of the normality tables will allow the MEH diagnosis in Portuguese patients with hepatic cirrhosis using an objective and internationally recommended method. Source

The ultrastructure of the spores and developmental stages of Ellipsomyxa mugilis in Nereis diversicolor were studied by transmission electron microscopy. The ultrastructure features and the developmental stages show many similarities with the general pattern described for other actinospores. However, several new features are definitely worth noting. For example, tetranucleated cells precede the formation of the initial pansporocyst, which preserves the 2 original enveloping cells until the end of sporogony. In the initial stages of sporogony, the future sporoplasm cell acquires the first secondary cell by an engulfment process. In the final stage of sporogony, spores are formed by a sporoplasm with 2 secondary cells and 1 somatic nucleus, and the polar capsule has a polar filament with a helicoidal arrangement possessing 78 coils. © 2012 American Society of Parasitologists.

The impairment of executive functions is one of the most robust deficits in depressive disorder. However, very few tools have been designed to assess briefly and specific executive functions in depression. This study aims to assess executive functions in patients with depression, examine the relationship between depression severity and performance of executive functioning, and verify the sensitivity and specificity of INECO Frontal Screening (IFS) compared with the Behavioural Assessment of Dysexecutive Syndrome (BADS) in the assessment of executive functions in patients with depression. 50 participants with depression (mean age = 43.46, SD = 10.71) and 35 participants in the control group (mean age = 40.91, SD = 10.46), of both genders, were evaluated by the IFS and the BADS. Participants with depression showed an executive functioning deficit compared to the control group in both the IFS and the BADS and the increasing severity of depression was accompanied by a greater impairment in executive functioning. IFS proved as sensitive and specific as the BADS in the detection of executive dysfunction in patients with depression. This study suggests that IFS is a brief, sensitive and specific tool to assess executive functions in depression. © 2014 Pontificia Universidade Catolica do Rio de Janeiro. All rights received.
