Effects of Maternal Pb2+ poisoning during pregnancy on the development of the jaw (Meckel´s Cartilage) of rat fetus

The purpose of this study was to investigate the effects of maternal lead poisoning during pregnancy on the development of the jaw (Meckel's cartilage) of rat fetuses by histologic and morphometric methods. Pregnant rats received a single intraperitoneal injection of 2.5 mg of lead acetate/100g body weight on the 10th day of pregnancy. Meckel's cartilage of fetuses of the lead-treated group showed smaller volume density and size of the lacunae, as well as modification of the lacunae shape. Moreover, the number density of lacunae and the volume density of the matrix increased significantly in the Meckel's cartilage in treated group fetuses. The results suggest that lead poisoning during the period of organogenesis can induce disturbances in the development and differentiation of the fetal stomatognathic system. Reducing the consumption of alcoholic beberages and smoking cessation by women in childbearing age, along with a strict policy of control of the environmental lead exposure can bring great benefits to the future generations of children.

Users' psychological characterization of the Birigui Mental Health Clinic

To improve mental health services, the World Health Organization proposes an “epidemiological approach” based on the constant screening of existing research, and aimed at continuous improvement of psychological treatment rather than strict application of prescribed techniques. This study provides an epidemiological survey conducted at the psychology ward of the municipal Ambulatório de Saúde Mental in Birigui, São Paulo, Brazil. Data from 180 patients in psychotherapeutic care were collected, and subsequent descriptive analysis showed that the population consisted predominantly of adults (82.8% of total) and females (81.0%). Depressive disorder was the most common symptom (61.1%), and the majority of the participants (72.2%) received psychological treatment for the first time. The data presented in this paper can assist mental health professionals in selecting appropriate treatment by creating a profile of patients.

Higienização em prótese sobre implante

With the advances of osseointegration principles, the use of implant-supported prosthesis has become a routine treatment option. The success of an implant is initially associated to the surgical technique, primary stability and absence of bacterial contamination on the implant site. Subsequently, the absence of mechanical trauma (overload) and peri-implantitis are sine qua non conditions to the longitudinal success of implant treatment. Therefore, the strict maintenance of oral hygiene is highly important to avoid biofilm accumulation around the implant and consequently to provide last-long implant-supported dentures. The clinician has the responsibility to supply a favorable prognosis to the patient so that the rehabilitation succeed. For this reason, during prosthesis fabrication the clinician should observe the design and emergency profile of the prosthesis, the peri-implant sulcus depth as well as the presence of motor or psychological impairment by the patient. Subjects with missing teeth and that will be submitted to the implant treatment should be motivated and adequate instructed regarding oral hygiene and its importance since the best option to obtain treatment longevity and consequently patient’s satisfaction is the prevention. Therefore, this study aimed to perform a literature review about the hygiene of implant-supported prosthesis.

Avaliação clínica e radiográfica de pacientes submetidos ao levantamento da membrana do seio maxilar

Implant dentistry is a dental specialty which presents great predictability in the rehabilitation at posterior, partially edentulous maxillary areas. Early tooth loss results in significant jaw remodeling. The maxillary sinus lifting followed by implant placement is a predictable technique initially described in 1980. Since then, several different techniques have been investigated varying filling materials and the management of complications in order to provide effective guidance in the rehabilitation of these patients. The current study evaluated ten patients who underwent sinus lifting before implant placement and crown installation. First, a retrospective analysis of the medical records was conducted to obtain information about possible postoperative complications. Clinical and radiographic analyses were performed at baseline and 180 days after surgeries. The sinus lifting with immediate implant placement provided satisfactory outcomes and can be considered a safe procedure. Treatment predictability was demonstrated in 90% of patients and for 86.96% of implants placed. It is important to highlight knowledge of anatomical structures at this area, the use of delicate surgical techniques, and strict patient follow-up.

Compreendendo a dinâmica familiar de adolescentes expostos a violência sexual intrafamiliar

Violence in adolescence, specifically sexual violence, is a topic of great relevance. Not only in Brazil but the world has witnessed the increase of sexual violence, becoming the most prevalent morbid occurrence in adolescence. Draws attention to the phenomenon of sexual violence against children and adolescents not only the fact that most of the victims are assaulted in their own home environment, but also the type of relationship between victim and aggressor. Thus, based on systemic approach, this study aimed to compose eend family dynamics of adolescent victims of sexual intra-familial. Participants were seven teenagers and their parents, users and beneficiaries of services offered by CREAS - Reference Center for Specialized Social Assistance in a municipality of Mato Grosso do Sul. The instruments used were the Test of Drawing in Colour of the Family (FCDT) and a questionnaire about the pictures taken and family interactions. The results indicated the difficulty in differentiating family roles, especially regarding the differentiation of the mother and daughter, a fact that seemed to be the motivator for the impoverishment of individuation in groups. Also noted the presence of conflict between the familiar figures probably originated from this abusive situation. In this context, the studied families showed communication difficulties between family members, hindering the integration between them, as well as the existence of an authoritarian leadership and strict rules performed by the father figure. These results may support preventive and therapeutic actions to situations of sexual violence against children and adolescents. Thus, it is suggested that psychological counseling for the study participants and other stakeholders with a view to reducing damage and recovery of quality of life for all family members, as well as the need for further studies in the area in question.

A concepção de sublimação no trabalho de Jean Laplanche

The theory of generalized seduction is a proposal for a new foundation to psychoanalysis that promotes a crucial metapsychological repositioning to rescue the other's role in subjectivity constituyion. The aim of this paper is to present and to discuss the concept of sublimation in this reference, working difficulties and limitations of a strict notion in which the concept appears as a mere modification of the object and the target of sexual drive. It is intended to discuss the limitations of this conception in its task of articulation between the individual subjectivity and the cultural organization, indicating the proposal of Jean Laplanche for originary sublimation and neoformation of drive, as attempts to overcome some of these theoretical and conceptual impasses. We conclude that Laplanche´s proposal is insufficient to account for the limitations in the theories of drives and culture in psychoanalysis, therefore, that it is a problem still current and relevant in this field of studies.

A study on the viability of minimum quantity lubrication with water in grinding of ceramics using a hybrid-bonded diamond wheel

With the currently strict environmental law in present days, researchers and industries are seeking to reduce the amount of cutting fluid used in machining. Minimum quantity lubrication is a potential alternative to reduce environmental impacts and overall process costs. This technique can substantially reduce cutting fluids in grinding, as well as provide better performance in relation to conventional cutting fluid application (abundant fluid flow). The present work aims to test the viability of minimum quantity lubrication (with and without water) in grinding of advanced ceramics, when compared to conventional method (abundant fluid flow). Measured output variables were grinding power, surface roughness, roundness errors and wheel wear, as well as scanning electron micrographs. The results show that minimum quantity lubrication with water (1:1) was superior to conventional lubrication-cooling in terms of surface quality, also reducing wheel wear, when compared to the other methods tested.

Estudo comparativo de diferentes metodologias analíticas para a determinação de fluoreto

The problem of dental caries in Brazil and around the world took major considerably over the years. In recent decades, with the advent of fluoridation, this problem has been alleviated. Studies have shown, however, that the lack of control in fluoridation leads to several health of the population. The strict control of fluoride levels in the water distributed, therefore, is essential. The objective of this study is to gather information on the status of fluoridation in some area of Brazil and compare different methods for the quantification of that analyte

Desenvolvimento de métodos cromatográficos para a padronização do extrato de Eugenia speciosa Cambess

The use of medicinal plants is common in many Brazil's ethnic groups, because the diversity of plant species in the country is large. But the utilization of these plants as standardized herbal doesn't occur with de same frequency, due the lack of studies related to these therapies, classified as alternatives. Due to the high cost of some synthetic medicines for the treatment of chronic diseases, phytotherapy is a low-cost alternative and efficient, since the phytomedication has proven scientific studies and its production meets strict criteria for manufacturing and quality control to ensure its safety and efficacy. Among the medicinal species used for the treatment of chronic diseases, such as pain and inflammation, is Eugenia speciosa Cambess, popularly known as the bush laranjinha. Against this context, this paper held preliminary studies and developed the chromatographic profile of the hydroalcoholic extract of the leaves of E. speciosa by High Performance Liquid Chromatography coupled to photodiode array detector (CLAE-DAD). Preliminary qualitative results and the chromatographic profile have identified some metabolites classes present and some constituent as: homogentisic acid, homorientina, isovitexin and quercetrin
