Pylephlebitis or suppurative thrombophlebitis of the portal mesenteric venous system is a rare but deadly complication of abdominal infections drained by the portal venous system. Usually, it is seen in the setting of appendicitis and diverticulitis. The incidence have been increased in the last years because of the use of modern diagnosis imaging such as ultrasonography and computed tomography scans. The more sensitive imaging techniques and the availability of antibiotics have improve the prognosis, although there is not consensus about the empiric antibiotic regimens and the anticoagulation therapy is a controversial topic.

In this work the theoretical response of YBaCuO in presence of microwave radiation is studied, by means the microwave absorption model in a swept magnetic field. The obtained results from the model fitted with those experimental results found in the literature for the YBaCuO. [ABSTRACT FROM AUTHOR]

Growth and mortality of the snail Astraea undosa were estimated based on the age determination of 1034 opercula obtained from 34,969 organisms sampled in five fishing areas off the west coast of Baja California Sur (Mexico), during 1997 and 1998. No significant differences were detected in the sizes of each sex and age groups of 0 to 12 yearswere determined. To describe the growth pattern, the von Bertalanffygrowth model was fitted to size-age data per fishing area and the following growth parameters were obtained: Linfinity = 167.8to 175.1 mm basal diameter, K = 0.08 to 0.10 mm/year and to = -l.7 to -l.2 years. The growth pattern was similar among areas in agreement with the performance index, Theta'. However, a north-south size-age latitudinal gradient was observed; the largest sizes per age were observed at Isla Natividad. The natural mortality was 0.29 per year. The total mortality rate per area varied from 0.43 to 0.90 per year and the exploitation rate from 0.11 to 0.40 per year. The results indicate that the fishery sustains appropriate exploitation levels. [ABSTRACT FROM AUTHOR]

Objective: This study examined the presence of disordered eating behaviours and the influence that on them could have the degree of body dissatisfaction among adolescents. Method: By the Eating Attitudes Test-40 (EAT-40), the Sick Control On Fat Food (SCOFF) and the subscale of body dissatisfaction (BD) of the Eating Disorders Inventory-2 (EDI-2) a total of 841 students, aged 12-19, were studied. Eating behaviours, sex and age differences, and eating attitudes and behaviours related to the degree of body dissatisfaction were analized. Results: We found that 2 1,29% had significant punctuations in the SCOFF and 7,13% in the EAT-40. There were significant sex-differences (13,93% and 3,23% in SCOFF and EAT-40 for males, 29,38% and 10,70% for women). With regard to previous studies, a decrease of the risk is observed in women and an increase in males. Major body dissatisfaction was observed among the 12 to 17-year-old girls, though sex-differences in eating alterations, can be mostly found between the ages of 14 and 16. Body dissatisfaction correlated positively and significantly to Body Mass Index, EAT-40 and SCOFF. Conclusion: In order to implement primary programs in the adolescent population it is necessary to explore the eating behaviours of risky and the degree of body dissatisfaction to be able to raise specifically the interventions to be carried out, involving teachers as primary agents for the work in the school context.

Background and objectives: The prejudice biases the categorization processes, which implies assigning particular characteristics beyond the objective data available. The stereotype occupies the categorical content by adding what is lacking to what we little know. From a mere physical datum ("he/she is fat") we categorize the obese individual on the basis of our own believes, intimately fusing the stereotype and categorization. Setting, population, and interventions: We included 138 students and 47 patients with anorexia or bulimia that assigned qualifying adjectives of the personality of obese people by using a list of epithets. This same list was provided to 49 obese patients in order to be used to define their own personality. Results: We analyzed the most frequently used epithets and the corresponding scales of personality by applying the X2 test to determine the differences between the adjectives and the scales in the samples. We considered a p value < 0.05 as being statistically significant, by using the SPSS v.13 software. Obese people define their personality very differently than the control group and the group of patients does. While obese people more frequently use "positive" adjectives, the other groups tend to use adjectives with more "negative" connotations. It seems that the stereotypes introduce a perception bias regarding the personality characteristics. The fear to overweight-obesity or the fact of "weight gaining" of patients would explain some of the findings of this work. Patients attribute obese people some personality characteristics altogether more negative than those attributed by the people in the control group. Conclusions: Knowing the influence of the stereotypes on obesity perception is essential to approach the patient with no prejudice regarding his/her treatment. The personality characteristics attributed to obese people are far from how these people really perceive themselves. [ABSTRACT FROM AUTHOR]

Background and objectives: In order to approach in a multidisciplinary way obesity and eating disorders it is necessary to know the implicit theories of personality, the stereotypes, and the current stigmatization of overweight, as well as making the obese individual guilty by attributing his/her state to a "way of being". The objective was to know the perception that students and patients with eating disorders may have about obese people and analyze the differences that might exist between both groups. Setting, population, and interventions: we selected 138 students and 50 patients with anorexia or bulimia that assigned qualifying adjectives to obese people from a given list. Results: We analyzed the most used adjectives and the corresponding personality scales by using the c² test to determine the differences between the adjectives used and the scales in both samples. A p value < 0.05 was considered to be statistically significant, using the SPSS software, v.13. Obese people were essentially qualified as introverted, inhibited, and cooperative. About the latter scale, we found differences due to the most frequent use of the terms "affectionate", "helping", "obliging", "dependent", and "obedient" by the patients. As a whole, there exists a negative perception of obese people. Among the most commonly used adjectives we may highlight: "excluded", "shy", "touchy", "anxious", "rejected", "insecure", and "passive", the latter being the most repeated one in both groups. The patients tend to preferentially choose some adjectives, which expresses a paradoxical fact: they seem to have a more lenient perception of obese people but they more often choose the terms "anxious", "solitary", "lazy", "lifeless", "dependent", "easily frightened", "lonely", "childish", or "impulsive". Conclusions: To know the perception of obesity is essential for the psycho-educative work and prevention of associated psychopathological impairments. In eating disorders obesity represents "the most feared" condition so knowing the underlying theories about obesity and overweight in these patients is essential for their management.

The periodic nature of the fabric images allows using fast Fourier transform techniques in image processing for its characterization. Due to the repetition of patterns inside the images of textile, is possible to find a form relatively easy of description in their energy spectrum. A recent work outlines a group of geometric descriptors for the Fourier spectrum of the images; looking for this efficiency to rotation, translation and scale change invariance [1]. These descriptors showed to be very effective to represent a textile fabric and can be used to characterize the quasi periodic textures in real time and in situ non destructive techniques. Samples of textile textures are tested to this technique of parametric representation with the purpose of analyzing their robustness and reproducibility. Finally, a set of textile fabrics is subjected to this model with the aim of evaluating the possibilities to carry out classification, verification and pattern recognition. [ABSTRACT FROM AUTHOR]

Introduction. To corroborate the hypothesis of hypofrontality in schizophrenia and to study the relationship between positive/negative symptoms (measured by the positive and negative syndrome scale [PANSS]) and regional cortical blood flow (rCBF), both at rest and during the Wisconsin Card Sorting Test (WCST) performance (activation). Methods. We compared a control group (n = 18) to a group of patients with schizophrenia (n = 21) in terms of rCBF, measured by single photon emission computed tomography (SPECT). Results. We found significantly higher left-frontal-CBF (during the WCST performance and at rest) and right-frontal-CBF (only at rest) in control subjects. Only the control group showed a right-frontal-CBF increase during activation. Only the patients group showed a significant right-occipital-CBF increase during the activation. We observed a positive significant correlation between the PANSS-P score and the left- frontal index at rest. Some negative symptoms such as difficulty in abstract thinking (N5) and lack of spontaneity and flow of conversation (N6) are associated to low frontal blood flow at rest. Affective blunting (N1) is associated to low left-frontal blood flow during activation. Conclusions. Our data support the hypothesis of hypofrontality, at rest and during activation, which means the incapacity of schizophrenic patients to increase the frontal CBF while performing the WCST (activation). Schizophrenia positive symptoms are associated to high left-frontal blood flow. [ABSTRACT FROM AUTHOR]
