Background: This case report presents the dimensional changes in dental arches in a patient with hypohidrotic ectodermal dysplasia (HED) after complete denture rehabilitation, with an 18-year follow-up period., Case Report: The patient had complete anodontia and was successfully rehabilitated with conventional complete dentures at 3, 4, 5, 7, 9, 12, 16, and 21 years of age. Each successive denture was larger and contained more and larger teeth so as to accommodate for the increase in the size of the developing jaw. A series of diagnostic casts were used to measure the dimensional changes in the arch length and width of the alveolar ridge. Cast analysis revealed that there was an increase in arch length and width in both the maxilla and mandible over time. Cephalometric analysis of craniofacial development was performed at 21 years of age, and suggested protrusion of the maxilla and mandible., Conclusions: The absence of teeth due to HED did not affect the dimensional changes in dental arches after complete denture rehabilitation from childhood to adulthood. The prosthetic treatment improved the patient's social integration and enabled the development of normal dietary habits, speech, and facial esthetics, which in turn led to improved quality of life.

Background: Contextual memory is susceptible to the effects of aging and its impairment compromises episodic memories and quality of life in older adults. Objective: Compare the effects of cognitive support on incidental contextual memory free recall and recognition with a naturalistic experimental paradigm and explore the association of encoding strategies and physical activity on memory improvement. Methods: Subjects (≥60 years, n = 52) were assigned to one of two encoding conditions for the contextual memory task: with or without an incidental associative instruction to encourage association of an item to its spatial context. Immediate free recall and recognition tests were run to assess the encoding instruction efficiency. The association of memory performance and physical activity was analyzed using the scores on the International Physical Activity Questionnaire (IPAQ) to subdivide each experimental group into Low IPAQ (below median) and High IPAQ (above median) subgroups. Results: The associative encoding instruction increased contextual memory free recall and recognition, with greater effects on free recall. The most robust associations between physical activity and contextual memory were also seen on free recall, in which higher levels of physical activity corresponded to increased baseline performance (non-associative encoding condition) and greater improvement of memory by the encoding support (associative encoding condition). Conclusion: Cognitive support at encoding can improve contextual memory free recall and recognition, suggesting they are prone to rehabilitation. Moreover, higher physical activity levels were positively associated with encoding strategies on contextual memory improvement, increasing the availability of latent process-based components of the cognitive reserve.

Familial caregivers of Alzheimer's disease (AD) patients experience an emotional and physical burden which characterizes a chronic stress condition. The resulting hypothalamic-pituitary-adrenal axis dysfunction favors an imbalance of neurotoxic/neuroprotective factors and causes cognitive impairments, increasing the caregivers' risk for cognitive decline and compromising their ability to provide adequate care of the patient. Therefore, the present study aimed to investigate the reversibility of the cognitive impairments of familial caregivers of AD patients during their caregiving-related chronic stress condition. Thirty-three caregivers (61.42 + 2.68 years; 27 women) and thirty-four controls (57.91 ± 2.16 years, 20 women) were evaluated for their cognitive functioning (attention, executive function, processing speed and memory) with a neuropsychological battery (Digit-span, Trail Making, Stroop and the Logical Memory tests). Subjects' cortisol/dehydroepiandrosterone (DHEA) ratios were determined by radioimmunoassay, and their brain-derived neurotrophic factor (BDNF) levels were analyzed by ELISA. An incidental contextual memory task, with or without an associative encoding instruction, was used to investigate if caregivers have a cognitive reserve prone to rehabilitation. The contextual memory impairment of caregivers was associated with prefrontal and hippocampal cognitive dysfunctions, alterations of the cortisol/DHEA ratio and lower BDNF levels. Even so, the contextual memory impairment could be improved by the associative encoding condition. This study suggests that the cognitive impairments of caregivers are not necessarily irreversible, as indicated by the results obtained for contextual memory, which could be improved despite the ongoing chronic stress and associated hormonal and neurotrophin dysfunctions. Lay summary The support of a relative with Alzheimer's Disease submits the familial caregivers to a chronic stress condition that increases their own risk of cognitive decline. This study suggests that, irrespective to their alterations on cortisol/DHEA ratio and BDNF levels, caregivers have a cognitive reserve that could probably be engaged to limit the negative effects of chronic stress on cognition.

Physical activity has been proposed as a promising intervention to improve cognition and decrease the risk of dementia in older adults. Brain-derived neurotrophic factor (BDNF) appears to mediate, at least partially, these effects of exercise. However, intervention studies of the effects of multimodal exercises on cognition and BDNF levels are scarce and composed by small samples. Thus, the generalization of the conclusions of these studies depends on the reproducibility of the results. In order to contribute to the knowledge on the field, the present study evaluated the effects of a physical activity intervention composed by muscle strengthening and aerobic conditioning on BDNF levels and cognition in older women. Independent and non-demented subjects (≥75 years) were assigned to a 3-month physical activity intervention (n = 22, 60 min exercise sessions three times a week) or to a control condition (n = 10, no exercise). Clinical (anxiety and depression symptoms), neuropsychological (Digit Span, Stroop, Trail Making, and Contextual Memory tests), physical (upper and lower limb strength, aerobic conditioning), and physiological (serum BDNF) parameters were evaluated immediately before, 1 month, and 3 months after starting intervention. Results indicated that controls had stable levels for all measured variables, whereas the intervention group improved on physical fitness, depressive symptoms, cognitive performance, and BDNF levels. Moreover, a linear regression identified an association between aerobic conditioning and BDNF levels. In conclusion, combined muscle strengthening and aerobic conditioning was able to improve cognitive performance and increase BDNF levels. Aerobic conditioning seems to be an important mediator of these outcomes.

This study focused on perceptions and practices in postpartum follow-up of women's health. The article is part of a larger qualitative study based on Gadamer, from October 2012 to September 2013 in Recife, Pernambuco State, Brazil, with participant observation and semi-structured interviews. Participation included the family health team (a physician, nurse, and five health agents) and ten women (18 years or older, recruited in the last trimester of pregnancy, and receiving prenatal care with the family health team). The empirical categories were access to care and health demands and needs. The results highlight dissatisfaction with home visits: late, without priority, absent physician or nurse, irregular and discontinuous; lack of postpartum appointment; and difficult access to the physician. The women expressed displeasure with the limited appreciation of women's health needs: attention focused on the infant, scarcity of physical examination and patient history, insufficient orientation, and limited communication. The incipient characteristics of postpartum follow-up in this study show the need to transform the health team's practices to focus more attention on the woman, thereby improving postpartum care.

Carya illinoensis is a widespread species, belonging to the Juglandaceae family, commonly known as Pecan. Popularly, the leaves have been used in the treatment of smoking as a hypoglycemic, cleansing, astringent, keratolytic, antioxidant, and antimicrobial agent. The following research aimed to identify for the first time the phytochemical compounds present in the leaves of C. illinoensis and carry out the determination of antimicrobial activity of aqueous and ethanolic extracts. The antimicrobial activity was tested against 20 microorganisms by determining the minimum inhibitory concentration (MIC). Phenolic acids (gallic acid and ellagic acid), flavonoids (rutin), and tannins (catechins and epicatechins) were identified by HPLC-DAD and may be partially responsible for the antimicrobial activity against Gram-positive, Gram-negative, and yeast. The results showed MIC values between 25 mg/mL and 0.78 mg/mL. The extracts were also able to inhibit the production of germ tubes by Candida albicans., (Copyright © 2017 Elsevier Ltd.

Objective: To evaluate women's care during home visits for the "First Comprehensive Care Week"., Method: A cross-sectional study was carried out in a specialized service in Recife, Pernambuco, Brazil. A total of 190 women who had recently given birth enrolled at the Family Health Strategy answered the questionnaire between September and December 2013 to verify the association between home visits and the investigated variables. This association was verified using the chi-square test with a confidence level of 95%., Results: Most of the women were 29 years old or under (68.5%), with high gestational risk (59.5%), and primiparous (46.9%). On the first week after hospital discharge, 42.1% received a home visit. An association was detected between local pre-natal care and a home visit on the first week (p = 0.049). The participation of the nurses during the visits was associated with better performance for breast and abdomen examinations (p = 0.000) and investigations on emotional conditions (p = 0.029)., Conclusions: These findings stress the need to establish a routine home visit plan to solve the issues of women with high-risk pregnancies after labour.

Objectives: Older familial caregivers of Alzheimer's disease patients are subjected to stress-related cognitive and psychophysiological dysfunctions that may affect their quality of life and ability to provide care. Younger caregivers have never been properly evaluated. We hypothesized that they would show qualitatively similar cognitive and psychophysiological alterations to those of older caregivers., Method: The cognitive measures of 17 young (31-58 years) and 18 old (63-84 years) caregivers and of 17 young (37-57 years) and 18 old (62-84 years) non-caregiver controls were evaluated together with their salivary cortisol and dehydroepiandrosterone (DHEA) levels, as measured by radioimmunoassays and ELISA assays of brain-derived neurotrophic factor (BDNF) in serum., Results: Although younger caregivers had milder impairments in memory and executive functions than older caregivers, their performances fell to the same or lower levels as those of the healthy older controls. Decreases in DHEA and BDNF levels were correlated with the cognitive dysfunctions observed in the older and younger caregivers, respectively. Cortisol at 10PM increased in both caregiver groups., Discussion: Younger caregivers were prone to cognitive impairments similar to older caregivers, although the degree and the neuropsychological correlates of the cognitive dysfunctions were somewhat different between the two groups. This work has implications for caregiver and care-recipient health and for research on the neurobiology of stress-related cognitive dysfunctions., Competing Interests: The authors have declared that no competing interests exist.

Background: Neuroimaging studies suggest that acute sleep deprivation can lead to adaptations, such as compensatory recruitment of cerebral structures, to maintain cognitive performance despite sleep loss. However, the understanding of the neurochemical alterations related to these adaptations remains incomplete., Objective: Investigate BDNF levels, cognitive performance and their relations in healthy subjects after acute sleep deprivation., Methods: Nineteen sleep deprived (22.11±3.21years) and twenty control (25.10±4.42years) subjects completed depression, anxiety and sleep quality questionnaires. Sleep deprived group spent a full night awake performing different playful activities to keep themselves from sleeping. Attention, response inhibition capacity and working memory (prefrontal cortex-dependent) were assessed with Stroop and Digit Span tests. Declarative memory (hippocampus-dependent) was assessed with Logical Memory test. Serum BDNF was measured by sandwich ELISA. Data were analyzed with independent samples T-test, ANOVA, ANCOVA and curve estimation regressions. p<0.05 was deemed statistically significant., Results: The sleep deprived group showed higher BDNF levels and normal performance on attention, response inhibition capacity and working memory. However, declarative memory was impaired. A sigmoidal relation between BDNF and Stroop Test scores was found., Conclusions: Increased BDNF could be related, at least in part, to the maintenance of normal prefrontal cognitive functions after sleep deprivation. This potential relation should be further investigated., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Background: The progressive loss of memory and autonomy of Alzheimer's Disease (AD) patients, together with their characteristic behavioral and psychological symptoms, subjects their family caregivers to chronic stress. Several studies indicate that these caregivers are predisposed to cognitive impairments, but the physiological correlates of these alterations remain to be elucidated., Objective: Analyze the effects of chronic stress of family caregivers of AD patients on cognition, cortisol/DHEA ratios and BDNF levels and investigate the relation between these variables., Experimental Procedure: Seventeen family caregivers (64.83 ± 3.64 years) of patients with AD and eighteen non-caregivers (58.29 ± 3.16 years) completed stress, depression and anxiety inventories. Exclusion criteria were current neurological disorders, major unstable medical illnesses, use of medications that could interfere with cognitive or HPA axis function and dementia. Attention, working memory and executive function were assessed with Digit Span and Trail Making tests, and declarative memory was analyzed with the Logical Memory test. Saliva was collected at 8 AM and 10 PM and its cortisol and DHEA levels determined by radioimmunoassay. Serum BDNF levels were measured by sandwich-ELISA. Results were analyzed with independent samples t test, covariance analysis and linear regressions. The statistical significance was set at p<0.05 and all p values were adjusted with Holm's Method., Results: Caregivers showed more stress, depression and anxiety symptoms than non-caregivers, as well as significantly worse performances on attention, working memory and executive function tests. Caregivers also had higher cortisol/DHEA ratios and lower BDNF levels than non-caregivers. Cortisol/DHEA ratios, especially at 10 PM, were negatively related with all cognitive tasks in which caregivers showed impaired performance. On the other hand, the only cognitive task that related with the BDNF level was digit span., Conclusions: This study showed that caregivers' cognitive impairment is related with alterations on cortisol/DHEA ratios, and that chronic stress experienced by these subjects has the potential to alter their BDNF levels., (Copyright © 2014 IBRO.

Background: The etiology of dentine hypersensitivity (DH) is still inconclusive and there are few studies concerning it in children., Aim: To evaluate clinical, dietary, and salivary variables in children with DH complaints., Design: Forty-eight children were asked about DH. Data regarding dietary habits were collected from the children's parents and an examination was performed to determine dental erosion. Dental biofilm was estimated by oral hygiene status, according to Greene and Vermillion's Simplified Oral Hygiene Index (OHI-S). Whole saliva was collected under mechanical stimulation and evaluated salivary flow rate, initial pH, buffer capacity, and calcium and phosphate concentrations. The temperature of soft drinks, drinking method, sense of bitter taste, and other variables were also determined. Possible factors associated with DH were analyzed by univariate and multiple Poisson regression analyses. The prevalence ratio (PR) values and 95% confidence intervals (95% CI) were calculated., Results: DH was associated with the presence of dental erosion (PR; 95% CI = 2.23; 1.05 to 4.71) and salivary flow rate (2.49; 1.05 to 5.91). When the presence of erosion was not included, other variables were retained as follows: bitter taste (2.36; 1.38 to 4.03), OHI-S (0.47; 0.23 to 0.97)., Conclusion: DH in children is associated with factors related to dental erosion.

Contextual memory is important for the encoding and retrieval of episodic memory, which is often impaired in euthymic patients with bipolar disorder (BD). The objective was to investigate the effect of low and high cognitive support on encoding in an incidental contextual memory task in euthymic patients with BD. Twenty-three patients with a BD type I diagnosis (aged 23-63 years, 17 women and 6 men) and 29 healthy controls completed a recognition memory task for context (location of a recognised object). Participants were assigned to one of two incidental encoding conditions: (1) with a binding cue to encourage the association of the object to its location (judging the degree of appropriateness of an object in relation to its location) or (2) without a binding cue (judging daily use of objects). Patients showed a deficit in incidental contextual memory in the absence of a binding cue at encoding. Under incidental encoding with the binding cue, no differences were observed between the groups for contextual memory. Contextual memory deficits in BD patients were reduced by providing cognitive support at encoding. The role of this strategy should be investigated in larger samples to evaluate its use for cognitive remediation in BD patients.

The unsustainable use of the soil of the deforested area at the Amazonian border is one of the greatest threats to the rainforest, because it is the predominant cause of shifting cultivation in the region. The sustainable management of soils with low natural fertility is a major challenge for smallholder agriculture in the humid tropics. In the periphery of Brazilian Amazonia, agricultural practices that are recommended for the Brazilian savannah, such as saturating soils with soluble nutrients do not ensure the sustainability of agroecosystems. Improvements in the tilled topsoil cannot be maintained if deterioration of the porous soil structure is not prevented and nutrient losses in the root zone are not curtailed. The information gleaned from experiments affirms that in the management of humid tropical agrosystems, the processes resulting from the interaction between climatic factors and indicators of soil quality must be taken into consideration. It must be remembered that these interactions manifest themselves in ways that cannot be predicted from the paradigm established in the other region like the southeast of Brazil, which is based only on improving the chemical indicators of soil quality. The physical indicators play important role in the sustainable management of the agrosystems of the region and for these reasons must be considered. Therefore, alley cropping is a potential substitute for slash and burn agriculture in the humid tropics with both environmental and agronomic advantages, due to its ability to produce a large amount of residues on the soil surface and its effect on the increase of economic crop productivity in the long term. The article presents some promising patents on the importance of an alternative for sustainability of agriculture.

The purpose of the present study was to evaluate the erosive potential of different types (concentrated and powdered) and commercial brands of industrialised grape juices. The pH of all five fruit drinks was measured at two time points: immediately after preparation and 24 hours later. Sixty specimens of bovine enamel were randomly allocated and immersed in different types of grape juice (n = 10) for 10 minutes four times a day for fifteen days. The enamel alteration was analysed using surface Knoop microhardness (KHN) and surface roughness (Ra) tests at baseline and on the 5(th), 10(th) and 15(th) days of the experiment. Two way ANOVA, Tukey's post hoc and Pearson's correlation tests were used for statistical analysis (α = 5%). The grape juices presented pH values ranging from 2.9 to 3.5. All of the tested juices promoted significant enamel mineral loss (p < 0.05) on the first evaluation (5(th) day of immersion) and produced a significant increase in the mean roughness from the 10(th) day on when compared to the control group (p < 0.05). By the 15(th) day, all of the beverages had produced surface roughnesses that were significantly higher than that of the control group. The results suggest that all grape juices, regardless of their commercial presentation, present erosive potential.

Objectives: To investigate the effect of cognitive support (an associative orienting instruction at encoding) on contextual memory in depressed patients., Methods: Seventeen patients (age 20-40 years, 14 women) diagnosed with major depressive disorder (MDD) and 22 healthy controls matched for age, gender and education completed a recognition memory task for item (object) and context (location), with or without an incidental binding cue at encoding. In addition, participants completed the vocabulary subtest of the Wechsler Adult Intelligence Scale (WAIS III) and the Wisconsin Card Sorting Test (WCST). Salivary samples were collected at 7 AM, 4 PM and 10 PM on the day of testing for cortisol and DHEA level measurement., Results: Depressed patients showed a deficit in contextual memory in the absence of a binding cue but did not differ from healthy controls in item memory or when a binding cue was present. Cortisol and cortisol/DHEA ratios were lower in depressed patients compared to healthy controls and correlated with memory deficits., Conclusions: Contextual memory deficits in MDD patients can be reduced by providing cognitive support at encoding., (Copyright © 2011 Elsevier B.V.

Aim: The finding of supernumerary teeth in the oral cavity is a common occurrence, and they are interesting because of their potential to lead to aesthetic and functional alterations. When they are present in the anterior area of the maxilla, they may cause complications, such as late tooth eruption or impaction of the central incisors. They affect from 0.5 to 3.8% of the population, with men being more affected., Case Reports: This article describes two cases of impaction of the permanent maxillary left central incisor, due to the presence of a supernumerary tooth in the parasagittal area of the pre-maxilla, as well as the surgical and orthodontic procedures adopted.

BaCKGROUND. The prevalence of dental erosion seems to be rising in young populations, particularly among individuals of higher socioeconomic status. AIM. To assess the prevalence and associated factors of dental erosion in children and adolescents of a private dental practice. DESIGN. A total of 232 participants, aged 2-20 years, were examined. Dietary habits, oral hygiene, and medical data were collected from dental records. Logistic regression analyses were conducted. RESULTS. Dental erosion prevalence was of 25.43% and was highest on the occlusal surfaces (76%). Associated factors were: frequent consumption of soft drinks (OR = 2.33; 95% CI = 1.01-5.38) and candies (OR = 3.23; 95% CI = 1.25-8.32); and interaction between these two factors (OR = 3.95; 95% CI = 1.60-9.75). On anterior teeth, associated factors were: frequent consumption of fruits (OR = 2.53; 95% CI = 1.09-5.91); and age (OR = 1.07 95% CI = 1.01-1.14). Milk consumption was associated with a lower prevalence of dental erosion (OR = 0.40; 95% CI = 0.17-0.94). CONCLUSIONS.  A relatively high prevalence of erosion was found in association with frequent intake of soft drinks, candies, and fruits. The consumption of milk seemed to protect against dental erosion on anterior teeth., (© 2011 The Authors.

This cross-sectional epidemiological study aimed to calculate the potential years of life lost by female homicide victims in Recife, Pernambuco State, Brazil, in 2003-2007. A database was used from the Operational Division for Information on Births and Deaths under the Recife Municipal Health Department. All death certificates for childbearing-age women were reviewed for the five-year period. The results showed a total of 12,120 potential years of life lost by these women, mostly young, black (88%), with unknown levels of schooling (78.2%), single (80%), in District III of the city, and murdered with firearms in their own homes. The specific mortality rate was 10.8 homicides per 100,000 childbearing-age women. The 43.3 years of life lost per woman express the city's characteristics, poverty levels, unemployment, population density, residential instability, and social inequality, exposing residents to social strife, crime, and violence.

The aim of this study was to assess the prevalence and risk indicators for erosive tooth wear (ETW) in Brazilian preschool children. A total of 967 children aged 3-4 years were examined. ETW was assessed using a modified version of the index recommended by O'Brien [London, Her Majesty's Stationary Office, 1994]. The 16 examiners were trained and calibrated. Hierarchical logistic regression was applied to investigate the association between ETW and socio-economic, environmental, nutritional and behavioural factors, as well as factors related to the child's characteristics. ETW was present in 51.6% of children. Most lesions were confined to enamel (93.9%) and involved over two thirds of the tooth surface's area (82%). There were no significant associations between ETW and socio-economic, environmental and nutritional variables. ETW was significantly associated with soft drink intake twice or 3 or more times a day (p = 0.043 and 0.023, respectively), frequent reported gastro-oesophageal reflux (p = 0.005) and age (p = 0.003). In conclusion, there was a high prevalence of ETW in the preschool children examined, and the risk indicators were frequent consumption of soft drinks, reported gastro-oesophageal reflux and age., (Copyright © 2011 S.

Objective: To assess the effect of a fluoride varnish and gel on the erosive wear of primary and permanent teeth., Design: Sixty human primary (n=30) and permanent (n=30) enamel specimens were randomly assigned to one of the following groups: APF gel (1.23% F), NaF varnish (2.26% F), and control (no treatment). Fluoride gel was applied for 4 min and fluoride varnish for 24 h. Six daily demineralisation-remineralization cycles of 5 min of immersion in a cola drink (pH 2.3) and 30 min in artificial saliva were conducted during 7 days. All specimens were stored in artificial saliva between and after cycles. Surface Knoop microhardness (%SMHC) readings were performed at baseline, 48 h and 7 days. Data were tested using ANOVA and Tukey's tests (p<0.05)., Results: For primary enamel, the mean %SMHC (+/-SD) after 48 h and 7 days was, respectively: gel (31.0+/-14.4 and 36.9+/-7.5), varnish (26.7+/-9.5 and 38.3+/-8.7), and control (35.8+/-8.6 and 45.0+/-8.6). For permanent enamel, such values were: gel (37.5+/-7.7 and 27.8+/-7.5), varnish (31.7+/-9.6 and 27.4+/-11.1) and control (48.6+/-6.4 and 43.1+/-6.4). In primary enamel, erosion inhibition by fluoride was not significant at 48 h (p=0.203) and 7 days (p=0.082). In permanent specimens, both products showed a significant effect (p<0.001)., Conclusions: Both fluoride varnish and gel were able to inhibit erosive enamel loss but mainly in the permanent experimental groups. Primary and permanent enamel substrates reacted differently to both demineralization by a cola drink and remineralization by fluoridated compounds.

Purpose: The objective of this study was to evaluate the presence and severity of dental erosion in cerebral palsy (CP) patients., Methods: A group of 48 noninstitutionalized individuals with CP, 2 to 18 years old (8.8+/-3.9 years), has been diagnosed with the disorder. Dental erosion was evaluated according to O'Brien. Results were compared to a control group composed by 26 patients with no neurological damage aged 4 to 18 years (11.3+/-3.5 years)., Results: Presence of deep dental erosion was significantly higher in CP individuals when compared to the control group. Concerning motor disorder, no statistical difference has been observed between the types of CP. Most of the affected teeth observed in the study group were the upper and lower molars and upper incisors., Conclusions: Cerebral palsy patients have a higher risk of dental erosion development.

This case report describes the esthetic dental treatment of a patient with Cohen syndrome where microabrasion was used to treat dental fluorosis. The patient's teeth had white and light yellow spots, which were diagnosed as moderate dental fluorosis. These spots were treated with microabrasion using pumice paste and 37% phosphoric acid. The paste was applied with a rubber cup on a low-speed handpiece and manually using a wooden stick. It took four appointments to treat all of the patient's teeth. Topical neutral fluoride was applied after each appointment to decrease any dental sensitivity. The esthetic result was satisfactory. Esthetic dental treatment may result in positive emotional and behavioral changes in patients with special needs.

Angelman syndrome (AS) is a rare genetic neurological disorder. The main clinical characteristics of this syndrome are delayed neuropsychological development, intellectual disability, speech impairment, movement or balance disorder, and a behavioural uniqueness. The syndrome has oral manifestations such as diastemas, tongue thrusting, sucking/swallowing disorder, mandibular prognathism, a wide mouth, frequent drooling, and excessive chewing behaviour. The dental literature on the syndrome is scarce. The purpose of paper is to describe the interesting aspects of the dental treatment of a child with AS.

Gingivostomatitis is the most common primary and symptomatic clinical manifestation of HSV-1 infection. Painful oral lesions appear as ulcerative erosions on the gingiva, palate, buccal mucosa, and tongue, leading to eating and drinking difficulties with an evolution between 10-14 days. This paper describes a case of a 19-month-old boy with severe painful Gingivostomatitis lesions. Low level laser therapy (LLLT) was used with an immediate outcome.

Purpose: The purpose of this study was to evaluate the occlusal characteristics of 104 randomly selected, noninstitutionalized patients with a medical diagnosis of cerebral palsy (CP)., Methods: Patients were grouped according to the CP motor disorder and clinical patterns. Occlusal characteristics were collected by one examiner. Nonparametric statistical tests, including Fisher's exact test (P) and chi-square test were used., Results: The results showed that Class II molars were statistically higher (P<.05) for spastic patients. Anterior open bite and an increased overjet were significant (P<.01) in spastic patients with clinical patterns of quadriplegia, double-hemiplegia, and diplegia. Double hemiplegia patients presented a higher incidence of open bite (64%) with an edge-to-edge overjet (45%). A deep overbite was presented in athetoid (50%) and ataxic (67%) patients. A high incidence of tooth wear was observed in the athetoid group (54%)., Conclusion: Spastic patients presented a high incidence of open bite and Class II malocclusion. A low level of malocclusion was observed in the ataxic group compared to the other groups studied. Further studies would be useful to determine if neurological injuries can be the cause of changes of the craniofacial growth and development patterns resulting in malocclusion in cerebral palsy patients.

Congenital Insensitivity-to-pain with anhidrosis (CIPA) is a rare disorder in which pain perception is absent from birth, despite the fact that all other sensory modalities remain intact or minimally impaired and tendon reflexes are present. The challenge in dentistry is to manage the self-mutilation behavior avoiding serious damages especially to oral structures, hands and fingers. A Brazilian case of CIPA is presented and discussed with clinical documentation of the oral-related problems over a 4-year follow-up. A conservative treatment (mouthguard-like appliance) was proposed with the objective to avoid full mouth extraction.

Background: The purpose of this study was to analyze the relation between enamel defects and delay of dental eruption with prematurity., Methods: the sample consisted of 100 premature children ranging from six months to six years of age, observed in the Children Institute of the Medical School of the USP. An anamnesis of the oral cavity was carried out by just one observer who analyzed the chronology of teeth eruption as well as the occurrence of enamel defects. A medical evaluation was also conducted in order to detect potential problems during the prenatal, neonatal and postnatal periods. The statistical assessment included descriptive analysis, average frequency and a confidence interval of 95%., Results: Defects appeared in 35% of the premature children; 51.43% of those affected had been born with a low weight (< 2500g), compared to 14.29% born with normal weight (> 2500g). No relationship was found between the occurrence of defects with a low Apgar score during the first minute, second minute and five minutes (p=0.628; p=0.308;p=0.,193). The most common defects were white opacities, in the deciduous (19.0%) as well as in the permanent dentition (100%). The incisor and cervical halves of the vestibular faces were the most affected reaching values of 88.04% for the deciduous dentition and of 100% for the permanent one. In about 42% of children eruption of teeth took place between 6 to 10 months of age., Conclusions: Premature children may have enamel defects caused by different factors that appear during pregnancy with a possible association between low weight and enamel defects. Furthermore, premature children had teeth eruption in a normal period, nevertheless, until 36 months of age with less teeth total than children born at normal term.

This is a case report of a 44-year-old male living in Teresópolis, RJ, Brazil, probably poisoned by contact with a Lonomia caterpillar, who presented hemolytic anemia, decreased platelet count and acute renal insufficiency. Lonomia erucism diagnosis was established by anamnesis and clinical and laboratory manifestations. Therapeutic measures consisting of hemotransfusion and hemodialysis were successful. Physiopathologic and clinical features of erucism by Lonomia are discussed.

A technique for the restoration of carious primary maxillary incisors using indirect resin composite crowns and intracanal reinforcement fiber is described. Endodontic treatment was previously performed on each tooth. The advantages of using an intracanal reinforcement fiber include resin composite crown reinforcement, translucency, and relative manipulation facility. In addition, the use of indirect resin composite crowns provides good shape and esthetics, as well as reduced chair time for the child. The technique is illustrated in a case report in which indirect resin composite crowns and an intracanal reinforcement fiber are placed in a 3-year-old girl.

The purpose of this article was to present a rare case of epidermoid cyst on the ventral region of the tongue in a 15-month-old child. During clinical examination, a sessile, yellowish lesion measuring approximately 0.5 cm was noticed. The lesion had existed since the child's birth and was causing discomfort due to friction of the tongue against the alveolar ridge during mastication. The chosen treatment was total removal of the lesion. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (1) a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (2) connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence.

This is concerned with a reflexive text that approaches the subject of the care to women that suffer conjugal violence in an analytic perspective of the world of the technique, developed from conceptions and concepts of Martin Heidegger, contemporary philosopher of phenomenology. The care of women that suffer conjugal violence appears as one that considers values, decision, trust to care, knowledge and care actions and its consequences.

Objectives: The infection levels of mutans streptococci were investigated during a one-year follow-up in children aged 12 to 30 months attending school nurseries where a sucrose-rich diet was provided., Methods: Oral levels of mutans streptococci obtained from 101 children at baseline and after a one-year follow-up were compared by age, number of teeth, feeding habits, and presence of visible plaque at baseline. Baseline predictors and changes in mutans streptococci levels during the study were compared to caries incidence after one year., Results: Fluctuations in mutans streptococci levels during the follow-up period were not related to feeding habits or presence of visible plaque. Mutans streptococci levels increased after one year among children aged 12 to 24 months, while a significantly higher proportion of those aged 25-30 months showed a decrease in mutans streptococci levels during the study. Multiple logistic regression analysis suggested that high levels of mutans streptococci (> or = 100 cfu) at baseline were associated with a higher caries increment, while reduction in mutans streptococci was negatively associated with caries incidence., Conclusions: Our data suggest that despite early mutans streptococci infection and high exposure to sucrose, mutans streptococci may achieve relatively stable levels after 2 years of age. Heavy colonization by mutans streptococci in an early age was related to an extremely high caries incidence during childhood, while decreasing levels of mutans streptococci can be associated to the decrease in caries activity.

For some adolescents, pregnancy means happiness and fulfillment. However, for most of them, it means a sad moment, characterized by fear and despair, as this is an unplanned situation and the abortion seems the only alternative. This retrospective study aimed at finding out the epidemiological profile of the adolescents admitted at the Clériston Andrade General Hospital, in Feira de Santana, Bahia, that were submitted to a curettage from January 1995 to December 1997. The results showed the need for educative programs in order to prevent unplanned pregnancies.
