Objectives: We attempt to investigate a possible association between periodontal disease (PD) and mental disorders (MD) in a population of Brazilian Police. Study Method: From a total study population consisting of 803 policemen, 345 police officers were obtained by a sample calculation using the finite population correction who were randomly selected in Montes Claros, Minas Gerais, Brazil. Patients who had been prescribed steroids or those diagnosed with diabetes and cardiovascular diseases were excluded from this study. The General Health Questionnaire (GHQ-12) was used to assess mental disorders. Odds ratios (ORs) for periodontal diseases severity and their respective 95% confidence intervals (CIs) were estimated. The risk of advanced scores in Clinical Attachment Level (CAL) and Community Periodontal Index (CPI) were estimated using Poisson Regression analyses. Results: Only smoking and age were associated with severity in CAL and CPI index. No relation between MD and PD was observed even in different positions within the police department. Conclusions: It was not observed relation between GHQ 12 and the incidence of Periodontal Disease in a Brazi-lian Police population. Classical factors like age and smoking, however, were associated with CAL and CPI index higher scores in this population. © Medicina Oral S. L.

Introduction: Reactional states are the main cause of nerve lesions and incapacities provoked by leprosy. Methods: Retrospective study aimed at verifying the frequency of leprosy reactions in discharged patients following cure by multidrug therapy (MDT). Results: Among patients who presented reactions during treatment, 35.5% continued after MDT; of those that did not present during treatment, only 12.7% presented after discharge; 63.4% multibacillary patients presented during and 31.7% after; 27.7% paucibacillary patients presented during and 8.3% after. Conclusions: A direct proportional relation exists between the presence of reactions during and after treatment. Multibacillary clinical forms present a greater frequency of reactions during and after cure.

This study aimed at determining which educational models have been applied to the activities health education. This is a review of literature on the topic Models of Education and Health Education, using as reference contemporary books of specialists in the field of education and journals on such topics available in major databases. The results showed that the Traditional Model of health education aims to transfer the knowledge and experience of the educator, giving a paramount importance to the content taught, hoping that the students absorb unchanged and faithfully reproduce. The model based on dialogue understands the in health education as a process of awareness, change and transformation, characterized by a philosophy of emancipatory subject.

Use of molecular markers can be limited by the high cost and extensive time required for their development. Transfer of simple sequence repeat (SSR) markers reduces the cost and time limitations and has allowed the use of these markers in a larger number of species. We tested 11 SSR markers previously developed for Anacardium occidentale on A. humile. The 11 loci were successfully amplified in A. humile. All loci were polymorphic and generated a mean of 5.4 alleles per locus. The observed heterozygosity was lower than the expected heterozygosity under Hardy-Weinberg equilibrium for most loci, with mean values of 0.463 and 0.696, respectively. The endogamy coefficients were positive and significant for seven loci. However, the combined probability of paternity exclusion was high, and the combined probability of genetic identity was low. None of the pairs of loci were in linkage disequilibrium. The informative power of these loci demonstrates that they are suitable for studies of diversity and genetic structure of natural populations of A. humile. In addition, the loci are suitable for estimating gene flow between populations, assessing species crossing preferences, and performing interspecific comparisons.

Macaúba (Acrocomia aculeata) is a palm of economic importance, widely distributed in natural forests from Mexico to Uruguay. We analyzed the genetic diversity of populations of macaúba (A. aculeata) in the northern region of the State of Minas Gerais, Brazil. Young leaves from 10 macaúba individuals encompassing 49 genotypes of macaúba were collected from Montes Claros, Itacambira, Brasília de Minas, Mirabela, and Grão Mogol. After extraction and amplification of samples, the amplified fragments were separated by electrophoresis. We found high levels of genetic diversity within the populations. Genetic diversity indices were high, except in the Itacambira and Mirabela populations. Results show that Mirabela and Itacambira populations can require conservation strategies because they present lower values of genetic diversity.

Mauritia flexuosa L. (Arecaceae) is a palm tree species known as buriti that occurs in the Cerrado biome. It is characteristic of the vereda, a typical ecosystem of central Brazil. In this phytophysiognomy, M. flexuosa and other groups of arboreal-herbaceous species develop in open fields with very humid soils. M. flexuosa can be found in forest borders and is a palm tree with a wide distribution in South America (Brazil, Colombia, Venezuela, French Guyana Ecuador, Peru, and Bolivia). The main objectives of this study were to develop simple sequence repeat marker-enriched libraries and to characterize these loci in buriti palm to facilitate future population studies. A total of 40 sequences derived from the microsatellite-enriched libraries were selected for primer design. The optimization results showed that 9 primer pairs could successfully amplify polymorphic target fragments of the expected sizes. The data also show that the described primers can be used in population genetic studies in M. flexuosa to obtain information that will inform conservation and management strategies.

To compare the prevalence of orofacial manifestations between patients with and without sickle cell anemia and to investigate the distribution of such events in patients with sickle cell anemia by sex and age. A cross-sectional study was conducted in which 330 subjects divided into two groups (a group of individuals with sickle cell anemia and a healthy control group) were examined. It was observed that patients with sickle cell anemia had a significantly higher prevalence of previous mental nerve neuropathy (P = .000) and delayed tooth eruption (P = .006) than patients without the disease. Regarding the distribution of orofacial manifestations in patients with sickle cell anemia by sex and age, the only statistical associations were between the prevalence of previous mental nerve neuropathy and sex (P = .023) and previous mandibular pain and age (P = .019). This study found that sickle cell anemia is associated with the prevalence of previous mental nerve neuropathy and delayed tooth eruption. Moreover, previous mental nerve neuropathy is more frequent among females with sickle cell anemia, and previous mandibular pain is more frequent among individuals older than 21 years of age with sickle cell anemia. Further studies using a methodology similar to the one in this study are necessary considering the scarcity of studies using this approach.

Gingival fibromatosis is an enlargement localized or generalized of the gingival tissue characterized by an expansion and accumulation of the connective tissue, predominantly type I collagen, with occasional presence of increased number of cells, supposed fibroblastic proliferation. Gingival fibromatosis can be induced as a side effect of systemic drugs, such as phenytoin, cyclosporin, and nifedipine, or due to hereditary factors. However, in some cases, the gingival overgrowth is idiopathic. This paper reports two cases of idiopathic gingival fibromatosis and discusses the diagnosis, histopathological features, treatment and immunohistochemical evaluation of myofibroblasts of this condition. The tissues removed were fixed in formalin, and sections used for hematoxylin and eosin and Masson tricromic stain. To determine the presence of myofibroblasts, we performed immunohistochemistry against a-SMA protein. Histological examination revealed epithelial hyperplasia with long rete pegs and increase in the dense fibrous connective tissue. The Masson tricromic stain revealed wide bundles of collagen strongly stained. It was showed negative labeling to a-SMA. These results strongly suggest that myofibroblasts are not involved in gingival overgrowth in the cases of IGF reported. Future studies will be necessary to determine the pathogenesis of idiopathic gingival fibromatosis.

This study evaluated the sealing ability of gray MTA-Angelus mixed with propyleneglycol in furcal perforations using a bacterial leakage test. Furcal perforations were created in 30 human mandibular molars using a size 3 round bur The samples were divided randomly into 2 experimental groups (n=10) according to the mixing agent. In G1, the MTA powder was mixed with propyleneglycol, while distilled water was used in G2. A 3:1 powder-liquid ratio was used for both groups. The MTA was placed in the perforation with an MTA carrier and condensed with hand pluggers. Non-repaired (n=5) and totally sealed (n=5) perforations served as positive and negative controls, respectively. Bacterial leakage was assessed daily for 30 days in a double-chamber apparatus with Enterococcus faecalis. Data were analyzed using Fisher exact test (p < 0.05) for three leakage periods: 1st to 10th day (P1); 11th to 20th day (P2); and 21st to 30th day (P3). The positive control presented leakage in all specimens within the first 24 hours, while no leakage was observed in the negative control during the experimental period. Leakage was observed in five (50%) of the 10 samples of the propyleneglycol group (G1) and seven (70%) of the distilled water group (G2) by the 20th day, without significant difference between the groups in periods P1 and P2 (p = 0.137). The leakage was significantly lower for G1 than G2 in period P3 (50% versus 100%, respectively, p = 0.016). In this single aerobic bacterial leakage method, the use of propyleneglycol as a vehicle for gray MTA-Angelus increased its sealing ability in furcal perforations at the end of the 30-day experimental period.

This paper reports a case of dengue in a six-year-old female child who suddenly developed excruciating headaches, fever, myalgia and paresis. Laboratory examinations included blood count, platelet count, biochemical tests (BUN, creatinine, aminotransferases, and total bilirubin and bilirubin fractions) and specific IgM titers (enzyme-immunoassay with recombinant tetravalent dengue). After ten days of hospitalization and having already been in a home environment, a new clinical image emerged, characterized by dysphagia, dysphonia, weakness, peripheral facial palsy and paresthesia. The diagnosis of Guillain-Barré Syndrome was based on clinical findings, cerebrospinal fluid examination, electrophysiological findings and the exclusion of other pathologies. Our case, as some shown in previous reports, calls attention to the possibility that Guillain-Barré Syndrome may occur in association with dengue.
