Over time, the understanding of the health-disease process has evolved along with the various environments and conditions in which society has been immersed, with different forms of care, treatment and prevention. Similarly, the social and economic structure has led to inequalities in medical care, generating social subclasses regarding access to health care and physical and functional capacities. This writing briefly introduces the social subclasses in health-disease that have emerged from the socio-economic structure of capitalism.

Introduction: Aluminium, a ubiquitous metal implicated in some neurodegenerative diseases is linked to activation of free oxygen species. The antioxidant-rich plants, Moringa oleifera (MO) is reported to protect against Aluminium activities. This study investigated the actions of MO leaf extract (MOLE) against Aluminium chloride (AlCl3 )- induced hippocampal cellular changes and serum levels of alkaline phosphatase (ALP), aspartate transaminase (AST) and alanine transaminase (ALT) in adult Wistar rats. Materials and Methods: Thirty Wistar rats weighing between 150 g and 220 g were grouped (n=5) into; 1-control (5 mL/kg distilled water), 2-AlCl3 (100 mg/kg), 3-low dose MOLE (250 mg/kg), 4-high dose MOLE (1,000 mg/kg), 5-concurrent AlCl3 and low dose MOLE, and 6-concurrent AlCl3 and high dose MOLE. All administrations were by oral gavages for 21 days. On day 22, following deep anaesthesia and cardiac puncture, blood was obtained for serum enzyme analysis, and the brain perfusion fixed, harvested and processed for histological study. Results: Results showed significantly (p < 0.05) higher ALP level in the AlCl3 group compared with the control, as well as the other test groups. However, there was no significant (p > 0.05) AST and ALT levels. The hippocampal CA3 of the AlCl3 group showed hypertrophic cells, with some of the cells having karyorrhectic features. The concurrent AlCl3 and low and high doses, MOLE groups showed less of these adverse features. Conclusion: These results suggest that MOLE may protect enzymatic activities against Aluminium chloride. However, its action on hippocampus is still subject to further investigation.

Third molars usually erupt within the age of 17 – 21years. Usually, due to the evolution of human jaws, the size is decreasing leading to the impacted tooth. An impacted tooth may lead to external resorption of the adjacent tooth, trismus, infection, etc. Many studies have been reported in the literature for evaluating the surgical difficulty and postoperative complications secondary to impacted third molars. This study includes a sample of 100 subjects evaluated for the surgical difficulty and postoperative complications. Various demographic, radiological, and intraoperative factors were evaluated which may lead to postoperative complications. Factors responsible for postoperative sequelae were also evaluated with complications. Postoperative pain after 4 hours and 7 days was assessed to mark the factors commonly responsible. Pain at 7th postoperative day was significant involving factors like fully impacted, horizontal impaction, level C, no/very little retromolar space, and root contact. Postoperative com­plications were not reported in this study.  

This study had as a goal to analyze the prevalence of suggestive images of atheromatous calcification in the common carotid artery, aiming to relate it to age, sex, antimere and to analyze the morphology of its calcification, through digital panoramic radiographs of the jaws. It’s an observational, transversal and retrospective study, on which there were analyzed 4.837 radiographs, that came from the files of a dental radiology private service in the city of Cabo de Santo Agostinho-PE, Brazil, referring to the period between 2011-2017. The morphology of the calcified atheromatous plaque was classified in: Grade I – normal (plaque not displayed); Grade II – intimal thickening; Grade III – simple plaque (less than 5mm thick); Grade IV – complex plaque (over 5mm thick) and Grade V – debris (irregular plaque with moving projections). The data collected was expressed in absolute values and frequency, analyzed through the chi-square, considering p< 0,05. Of the analyzed radiographs, 1.321 filled the eligibility criteria, of these 51 (3,8%0 presented suggestive image of atheromatous plaque, 71% were of the female sex (p = 0,003), 45% were at the age range between 5th and 6th decade of life (p= 0,001), most of the identified plaques were unilateral, to the left (p=0,02) and 76% were morphologically classified as grade III (less than 5mm thick). In this study, it was verified the low prevalence of suggestive images of atheromatous in carotid artery, with greater occurrence on the female sex, between the 5th and 6th decade of life, unilaterally, to the left and morphologically classified in grade III.

Countless studies carried out by different health areas demonstrate the benefits of exclusive breastfeeding (BF) and the harmonious growth of craniofacial structures for the proper subsequent development of oral functions such as breathing, swallowing and speech. Early intervention by the professional in speech therapy in Intensive Care Units (ICU) shows undeniable benefits as it promotes self-efficacy in the mother, breastfeeding and with it, the reduction of comorbidities in the baby, as well as the reduction of time for the implementation of the oral route. It is important to highlight the importance for the speech pathologist to have validated instruments that allow timely diagnoses and therefore effective treatments. This research is descriptive, with a mixed methodology and non-experimental design; Since it was oriented towards the verification of the validity of the content (external) of the EFIN Comprehensive Speech Therapy Assessment Protocol of the Newborn, also determining its relevance, as it is used as a guiding instrument within the role of the speech therapist in breastfeeding. For validity purposes in terms of sufficiency, relevance and clarity, the validation is carried out through the judgment of experts, with a panel made up of professionals from different Latin American countries, including Colombia, Peru, Chile, Brazil and Argentina, obtaining strong validity of the entire protocol, with a validity coefficient according to Aiken’s V statistical coefficient greater than 0.81. To measure the usefulness of the EFIN instrument in the approach to breastfeeding, a Likert-type survey is carried out observing homogeneous absolute frequencies that allowed us to see the instrument as a very useful tool, not only for breastfeeding but for all areas of neonatology in which the speech therapist participates. Keywords: Stomatognathic functions; communication; neonates; breastfeeding; speech therapy. 

Introduction: according to scientific literature, does low-power laser promote acceleration of tooth movements during orthodontic treatment? Objective: to systematize the ability of the low-power laser to accelerate tooth movements during orthodontic treatment. Material and methods: a systematic review was carried out, a search using Boolean search engines on the PubMed platform. The keywords used for were: orthodontic movement, orthodontic tooth movement, orthodontic, orthodontic treatment, low level laser therapy, low level laser, laser therapy and the combination between them. The included investigations dealt with the issue of acceleration of tooth movement during orthodontic treatment using low-power laser, were from journals indexed in PubMed, clinical trials, in English, and corresponded to articles published since 2000 to date. Assessment of risk of bias was performed. The variables analyzed were: main author, title, year, type of article, journal, country of research, and whether the articles show that low-power laser increases tooth movement during orthodontic treatment. Results: 60% of the included studies conclude that the low-power laser accelerates tooth movement during orthodontic treatment, 30% of these did not find significant changes in relation to the groups studied with those of control and 10% resulted in dubious conclusions. Conclusions: although the results are encouraging due to the trend in which the low-power laser does accelerate orthodontic movements, the presence of a higher number of randomized clinical studies would be necessary for a specific clarification of the benefits that this therapy brings to the patient. sector.

Rhinoplasty is one of the most frequent cosmetic surgeries in the world and among the most common complications is valve collapse due to excessive resection of the alar cartilage. Facial paralysis, as well as aging, can collapse the lateral wall in inspiration due to dysfunction of the nasal muscle, causing weakening of the fibroalveolar tissue of the nasal lateral wall, and there are also genetic causes that produce valve collapse. Currently, various techniques are practiced to improve valve collapse and none are one hundred percent effective, most of them focus on correcting the nasal valve itself or the triangular cartilage, which indicates that they are fixed on a single factor and not on multifactorial etiology that produces it. This study reviews the clinical evidence that guides a correct diagnosis and effective management of external nasal valve dysfunction, using various techniques that are currently used to improve nasal valve collapse.

Primary splenic lymphomas involve the spleen and/or its lymph nodes. They represent <1% of lymphomas and they imply a diagnostic challenge due to its poor symptomatology and low prevalence. There for, the objects this work describe the management and evolution of a patient with HIVAIDS and presentation of a primary lymphoma of the spleen. In this report we present the case of a 52-year-old male patient with HIV infection without treatment presented with abdominal pain, fever and a 2-month weight loss. The pre-operative computed tomography showed splenomegaly and hypodense lesions suspected to be tumoral. He was operated on, performing an exploratory laparotomy, performing an splenectomy. The histopathological study reported a non-Hodgkin lymphoma. Primary splenic lymphoma is a non frequent entity. It is necessary to be acquainted with it in order to suspect it.

Provide recommendations for safeguarding the practice of the profession in the myofunctional area in a safe way, both for the speech therapist and for its users, documented in relevant scientific publications. Methods: it constitutes an integrating review. The search was performed through the Lilacs, Pubmed, SciELO databases, and various web pages were consulted, under the terms COVID-19; SARS-CoV 2; security protocol; COVID-19 suggestions and COVID 19 action guides. Results: Recommendations are proposed for speech pathologist linked to myofunctional therapy in various contexts. Discussion: the correct identification of these recommendations represents an absolute top-priority action so that professionals can instruct the behaviors related to patient safety and continue the treatments in COVID-19 context, increasing the protection, with the purpose of preventing infections in the process.

Use of low level laser therapy (LLLT) in bone healing has been studied for years, and its application in implant dentistry is still a controversial topic due to the difficult assessment of its clinical efficacy. We report the application of LLLT as aid in the osseointegration in two patients undergone to implant surgery in the upper jaw. In one hemi-arch the LLLT was applied and the other one was used as control. The assessment of the bone area surrounding the fixtures was performed by means of cone beam compute tomography and the area of bone-implants contact was measured by means of InVesalius® software. The radiological findings support the idea of considering the laser biostimulation as an adjunctive aid in implant surgery
