RESUMEN

Grape seeds are rich in bioactive substances, including polyphenols, terpenoids, and phytosterols. Linseed (Linum usitatissimum L.) boasts a high concentration of polyunsaturated fatty acids (PUFAs), lignans, phytoestrogens, and soluble fibers, all contributing to its therapeutic potential. In this study, we pioneered the formulation of an oil blend (GL) combining grape seed oil (G) and golden linseed oil (GL) in equal volumes (1:1 (v/v)) and we evaluated in terms of the nutritional, physical, and chemical properties and their influence in an in vivo experimental model. We analyzed the oils by performing physical-chemical analyses, examining the oxidative stability using Rancimat; conducting thermal analyses via thermogravimetry/derivative thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC), performing optical UV-vis absorption analyses; examining the fluorescence emission-excitation matrix, total carotenoids, and color, and conducting metabolic assessments in an in vivo experimental trial. The fatty acid profile presented a higher fraction of linoleic acid (C18:2) in G and GL and alpha-linolenic acid (C18:3) in L. The acidity and peroxide indices were within the recommended ranges. The TG/DTG, DSC, and Rancimat analyses revealed similar behaviors, and the optical analyses revealed color variations caused by carotenoid contents in L and GL. In the in vivo trial, G (G2: 2000 mg/kg/day) promoted lower total consumption, and the blend (GL: 2000 mg/kg/day) group exhibited less weight gain per gram of consumed food. The group with G supplementation (G2: 2000 mg/kg/day) and GL had the highest levels of HDL-c. The group with L supplementation (L2: 2000 mg/kg/day) had the lowest total cholesterol level. The L2, G1 (1000 mg/kg/day), and G2 groups exhibited the lowest MCP-1 and TNF-α values. Additionally, the lowest adipocyte areas occurred in G and GL. Our results suggest that this combination is of high quality for consumption and can influence lipid profiles, markers of inflammation, and antioxidant status.

RESUMEN

Introdução: No Brasil, queimaduras acometem cerca de um milhão de pessoas/ano, a maioria do sexo masculino. Além de prejuízos físicos e emocionais, há impacto econômico, com gastos para o sistema de saúde, indenizações e incapacidades laborais. Por estas razões, estudos epidemiológicos são importantes para traçar o perfil da população mais acometida, orientando a prevenção dessa afecção. Método: Revisão dos prontuários de 398 vítimas de queimaduras, internados na Santa Casa de Santos, de janeiro de 2016 até dezembro de 2019. Resultados: Os principais acometidos são homens, jovens, em ambiente doméstico, por líquidos aquecidos, causando em sua maioria queimaduras de segundo grau, atendidos em até 24 horas, considerados grandes queimados e internados em enfermaria por até duas semanas. Aproximadamente 90% recebeu alta com melhora, necessitando apenas de desbridamento e curativos. Conclusão: Nosso trabalho concorda com maioria das revisões em relação à prevalência do sexo masculino, jovens, economicamente ativos, em suas residências, com líquidos aquecidos, acidentalmente. Outros estudos apontaram crianças como as mais afetadas, mostrando necessidade de políticas voltadas a ambas as faixas etárias. Com relação à internação, a maioria permaneceu em enfermaria, com queimaduras de segundo grau, prevalecendo os grandes queimados, o que acarreta maior gravidade e custos. Esse dado vai contra alguns trabalhos, que apontam queimadura de segundo grau como principal, porém com menos de 10% da superfície corporal queimada. A maior parte dos pacientes, tanto neste quanto na maioria dos estudos, apresentou bom desfecho, sem necessidade de Unidade de Terapia Intensiva ou procedimentos cirúrgicos, mostrando a importância do desbridamento precoce e cuidados com curativos.


Introduction: In Brazil, burns affect around one million people/year, the majority of whom are male. In addition to physical and emotional losses, there is an economic impact, with costs for the health system, compensation, and work disabilities. For these reasons, epidemiological studies are important to outline the profile of the most affected population, guiding the prevention of this condition. Method: Review the medical records of 398 burn victims admitted to Santa Casa de Santos from January 2016 to December 2019. Results: The main victims were young men in a domestic environment, by heated liquids, mostly causing second degree burns, treated within 24 hours, considered major burns, and admitted to the infirmary for up to two weeks. Approximately 90% were discharged with improvement, requiring only debridement and dressings. Conclusion: Our work agrees with most reviews regarding the prevalence of young, economically active males with accidentally heated liquids in their homes. Other studies highlighted children as the most affected, showing the need for policies for both age groups. Regarding hospitalization, the majority remained in the ward, with second-degree burns, with major burns prevailing, which leads to greater severity and costs. This data goes against some studies, which indicate second-degree burns as the main burn, with less than 10% of the body surface burned. In both this and most studies, most patients had a good outcome, without needing an Intensive Care Unit or surgical procedures, showing the importance of early debridement and care with dressings.

RESUMEN

This dataset describes the analysis of aflatoxins, macroelement and microelement concentration, oxidative stability and fatty acid profile of infant formula milk powder. Gas chromatography (CG) was used to identity 14 fatty acid methyl esters in in five samples of oils. The Racimat 893 method (induction times), Thermogravimetry (TG), Derivative Thermogravimetry (DTG) and Differential Scanning Calorimetry (DSC) were used to estimate the oxidative stability of oils. In addition, UV-VIS spectroscopic techniques were employed to obtain graphs of the absorption of each oil. The data presented can be useful in identifying compounds available in oils used to promote wound healing and understand the degradation mechanism.

RESUMEN

BACKGROUND: Studies indicate that different parts of Carica papaya Linn have nutritional properties that mean it can be used as an adjuvant for the treatment of various pathologies. METHODS: The fatty acid composition of the oil extracted from the seeds of Carica papaya Linn was evaluated by gas chromatography, and an acute toxicity test was performed. For the experiment, Swiss mice were fed a balanced or high-fat diet and supplemented with saline, soybean oil, olive oil, or papaya seed oil. Oral glucose tolerance and insulin sensitivity tests were performed. After euthanasia, adiposity, glycemia, total cholesterol and fractions, insulin, resistin, leptin, MCP-1, TNF-α, and IL-6 and the histology of the liver, pancreas, and adipose tissue were evaluated. RESULTS: Papaya seed oil showed predominance of monounsaturated fatty acids in its composition. No changes were observed in the acute toxicity test. Had lower food intake in grams, and caloric intake and in the area of adipocytes without minimizing weight gain or adiposity and impacting the liver or pancreas. Reductions in total and non-HDL-c, LDL-c, and VLDL-c were also observed. The treatment had a hypoglycemic and protective effect on insulin resistance. Supplementation also resulted in higher leptin and lower insulin and cytokine resistance. CONCLUSIONS: Under these experimental conditions, papaya seed oil led to higher amounts of monounsaturated fatty acids and had hypocholesterolemic, hypotriglyceridemic, and hypoglycemic effects.

RESUMEN

The consumption of regular vegetable oils has been linked to energy acquisition, nutritional benefits, health improvement, and the regulation of metabolic diseases. This study evaluated fatty acids composition, physicochemical, thermal, oxidative, and optical properties, and quantified trace elements in the sunflower oil extracted by a domestic cold-press machine. The oil presented linoleic (54.00%) and oleic (37.29%) primary unsaturated fatty acids (91.67%), in which atherogenic (0.05), thrombogenic (0.16), hypocholesterolemic/hypercholesterolemic (21.97), peroxide (16.16), saponification (141.80), and relative density indices (0.92) demonstrated to be suitable for human consumption and possible health promotion. In addition, the concentrations of trace elements by ICP OES were ordered Zn > Fe > Al > Cu > Mn > Cr. Concentrations of Zn, Fe, Al, Cu, and Mn were lower than FAO/WHO and DRI/AI limits, while Cr concentrations exceeded the FAO/WHO limits, which can be used as an indicator of the polluted ambiance. Sunflower oil quantities daily consumption were calculated by taking into account non-carcinogenic risk (CR < 10-4), and total non-carcinogenic hazard index (HI < 1). Based on trace elements determined in this study, the suitable quantity of sunflower oil consumption varies according to individuals aged 8, 18, and 30 years and will be deemed 0.61, 1.46, and 1.65 g/kg, respectively, attending HI = 0.99 and CR < 10-4.

RESUMEN

An experiment was conducted to evaluate the fatty acid profile of subcutaneous fat from barrowS of same genetic lineage supplemented with organic chromium and selenium initiated in different weight ranges in the finishing phase using 24 carcasses. Three different diets were used that represent the time when supplementation starts: control - without the inclusion of organic Cr and Se; CrSe70 - control with 500 g ton-1 of organic Cr and Se of 70 to 130 kg in body weight; and CrSe100 - control with inclusion of 500 g ton-1 of organic Cr and Se from 100 kg to 130 kg body weight. Performance, carcass characteristics, and lipid profile were evaluated. The data were submitted to analysis of variance, and with significant differences (p<0.05), the means were compared using the Tukey test. From 70 to 100 kg, control and CrSe70 animals consumed less feed than CrSe100. From 100 kg body weight, it reduced the C20:5n3 and C24:1n9 acids and increased the activity of the Δ-6 desaturase, elongase, Δ-5 desaturase enzymes in the supplemented animals. The moment when supplementation starts of organic chromium and selenium does not improve the performance and carcass characteristics, does not change the fatty acid profile, and does not improve the quality of the fat.

RESUMEN

Mauritia flexuosa (Buriti) pulp oil contains bioactive substances and lipids that are protective against cardiovascular and inflammatory diseases. We performed physical and chemical analyses to verify its quality and stability. Buriti oil was stable according to the Rancimat test, presenting an induction period of 6.6 h. We evaluated the effect of supplementation with crude buriti oil and olive oil on metabolic parameters in 108 Swiss mice for 90 days. We investigated six groups: extra virgin olive oil (EVOO) 1 and 2 (1000 and 2000 mg/kg), buriti oil (BO) 1 and 2 (1000 and 2000 mg/kg), synergic (S) (BO1 + EVOO1), and control (water dose 1000 mg/kg). The animals were euthanized to examine their blood, livers, and fats. The supplementation did not interfere with food consumption, weight gain, and histological alterations in the liver. Group S showed the strongest relationship with the fractions HDL-c and non-HDL-c, indicating a possible cardioprotective effect. Moreover, we observed significantly higher IL-6 levels in the control, EVOO2, and BO1 groups than in the EVOO1 group. Resistin was also significantly higher for the synergic treatment than for the control. We conclude that BO combined with EVOO could be an excellent food supplement for human consumption.

RESUMEN

Studies comparing methodologies for fatty acids are very important, since they can influence the quality and final quantification of the lipid fraction. Objective-to compare different extraction methods for total lipids and to evaluate the effect of these methodologies on the quantitative composition of fatty acids in milk of lactating ewes raised in tropical pastures. The methodologies used were simple direct transesterification, using the HPLC grade organic solvent n-hexane, Bligh; Dyer (cold extraction, extracting mixture proportions 5, 10, and 15 mL in a ratio of 2:1:1 (v/v/v) of chloroform-methanol-water). The fatty acid methyl esters were separated by gas chromatography coupled with a flame ionization detector (GC-FID). The results show that there was no significant difference (p <0.05) in the total lipid content between the extraction methods. However, the Bligh's method; Dyer obtained the best yield of lipids to be extracted from ewe's milk, since the volume with 15 mL of the extraction solution was able to identify 87% of the chromatographic peaks. It was also observed that ewe's milk has a higher percentage of palmitic, stearic and oleic fatty acids, with percentages of 20.1%, 15.5% and 33.1%, respectively. Therefore, an extraction mixture with a volume of 15 mL used in this study may be an alternative to perform the extraction of milk fat from high lactating ewes in tropical pastures as a routine method, as it expresses the best lipid content of this food.

RESUMEN

Oils extracted from almonds are often used with particular interest due to their prospective health effects and benefits. Tucum is a Pantanal fruit widely consumed by local population and no in vivo toxicity studies regarding its safety are available in the literature to date. This study investigated the acute and subacute toxicity of tucum almond oil (TAO) in mice by evaluating its safety profile. For the acute (2000 mg/kg) and subacute (250, 500 and 1000 mg/kg) toxicity studies, TAO was administered orally to mice according to 425 and 407 Organization for Economic Cooperation and Development Guidelines, respectively. Food intake, body, and organ weight of animals were recorded. Signs of toxicity were assessed, and hematological, biochemical and histopathological analyses were performed. In the acute toxicity study, no mortality or behavioral changes were observed in mice treated with 2000 mg/kg, indicating that LD50 is higher than this dose. In the subacute toxicity test, the doses evaluated did not produce relevant changes in hematological, biochemical or histopathological parameters in the exposed animals. The data obtained suggest that TAO did not induce toxicity after exposure to a single or repeated doses and LD50 value may be considered to be more than 2000 mg/kg body weight.

RESUMEN

Obesity is a relevant health hazard characterized as a chronic noncommunicable disease, with severe comorbidities that cause mortality worldwide. Acrocomia aculeata is a Brazilian palm with edible fruits. Its pulp contains fibers, monounsaturated fatty acids (MUFAs), such as oleic acid and carotenoids. In this context, our study aimed to elucidate the protective effect of the lyophilized A. aculeata pulp added at the rates of 1%, 2%, and 4% to a high-fat (HF) diet (rich in saturated fats and cholesterol), for 90 days, in mice. The treatment with 4% pulp induced a significant increase in the biochemical parameters of serum cholesterol HDL-C (high-density lipoprotein) compared with the control. According to the evaluation of the epididymal tissue, the groups treated with A. aculeata pulp exhibited smaller fat deposits compared with the HF diet group. Therefore, we infer that the predominant components in A. aculeata, particularly fibers and MUFAs, promote beneficial effects on health parameters during simultaneous exposure to food rich in saturated fat and cholesterol, typical of the Western diet. This is the first study to correlate the presence of fatty acids from A. aculeata pulp in different proportions added in a HF diet with metabolic and histological parameters in Swiss mice.

RESUMEN

This study was conducted to evaluate the period of chromium yeast supplementation on lipid profile of backfat and Longissimus lumborum muscle of barrows. It was evaluated carcass samples from forty barrows, genetically similar. Pigs diets were supplemented with 0.4 mg kg-1 of chromium yeast in four periods (0, 38, 62 and 94 days before slaughter). The experimental design was completely randomized with four treatments, ten replicates, and each experimental unit consisting of one animal. Lipid profiles of backfat and Longissimus lumborum muscle were analyzed by gas chromatography. The increase in the period of chromium yeast use had a quadratic effect (P<0.05) for stearic and oleic fatty acids, and total saturated, monounsaturated and unsaturated fatty acids in backfat. DH-γ-linolenic and arachidonic fatty acids reduced when the period of chromium yeast use increased. In the meat, there was a quadratic effect (P<0.05) only in the γ-linoleic fatty acid. The use of chromium yeast for different periods influences the lipid profile of the backfat and the Longissimus lumborum muscle, with less effect in the meat.

RESUMEN

Metabolic syndrome (MetS) and obesity are growing in many parts of the world, becoming public health problems. It is proposed that foods with functional properties can assist in the treatment of these diseases. Crude buriti pulp oil (BPO) is a food traditionally consumed by residents in the Pantanal, Cerrado and Brazilian Amazon. It is rich in oleic acid, tocopherols and carotenoids, emerging as a potential functional food. Thus, this study aimed to evaluate the effect of the supplementation of BPO on metabolic disorders caused by a high-fat diet. Four groups of C57BL6 mice were used, a lean group with AIN-93M diet and control oil supplementation, an obese group with a high-fat diet and control oil supplementation, and two obese groups with a high-fat diet and BPO supplementation in the amounts of 50 and 100 mg/kg. BPO worsened the metabolic state caused by the high-fat diet, worsening risk factors associated with MetS, as the abdominal circumference and retroperitoneal fat, serum levels of total cholesterol, uric acid, alanine transaminase, glucose and triglycerides, and renal fat, in addition to changes in glycaemic control and oxidative stress markers. C57BL/6 mice fed with a high-fat diet and supplemented with BPO presented a worsening in metabolic risk factors associated with MetS.

RESUMEN

Introdução: As mamas e o abdômen passam por grandes modificações morfológicas com perdas ponderais maciças. A mamoplastia de aumento é um dos procedimentos mais realizados na cirurgia plástica, ao contrário da abdominoplastia reversa, pouco descrita. Porém, em pacientes com flacidez abdominal superior que desejam o aumento mamário, a mamoplastia de aumento por meio da abdominoplastia reversa (AMBRA) torna possível o aprimoramento das mamas e do contorno abdominal simultaneamente. O objetivo deste trabalho é descrever um caso de mamoplastia de aumento e mastopexia utilizando retalho em cambalhota a partir de abdominoplastia reversa. Relato de Caso: Paciente do sexo feminino, parda, com história de perda ponderal maciça e com mamoplastia redutora e abdominoplastia prévias, evoluiu com ptose mamária e lipodistrofia em abdômen superior. Foi submetida à abdominoplastia reversa com utilização do retalho dermogorduroso epigástrico para projeção da mama. A paciente apresentou boa evolução pós-operatória, com resultado cirúrgico satisfatório. Discussão: As perdas ponderais maciças podem resultar em deformidades nas mamas e no abdômen que exigem cirurgias reparadoras. A remodelação mamária é difícil e pode exigir a utilização de tecidos adjacentes. A abdominoplastia, por sua vez, é a técnica mais consagrada para o rejuvenescimento do tronco; entretanto, quando a flacidez atinge principalmente o abdômen superior, a abdominoplastia reversa torna-se uma opção. Em casos em que o desejo de mamoplastia de aumento se associa ao excesso de volume supraumbilical, deve-se considerar a AMBRA. A mamoplastia de aumento por meio da abdominoplastia reversa revelou ser uma técnica viável neste caso, com resultado final satisfatório.


Introduction: The breasts and abdomen undergo significant morphological changes with massive weight loss. Breast augmentation is one of the most commonly performed procedures in plastic surgery, unlike reverse abdominoplasty, which has been little described. However, in patients with upper abdominal flaccidity who want breast augmentation, breast augmentation through reverse abdominoplasty (AMBRA) makes it possible to improve the breasts and abdominal contour simultaneously. This work aims to describe a case of breast augmentation and mastopexy using a somersault flap from reverse abdominoplasty. Case Report: Female patient, brown, with a history of massive weight loss and previous mammoplasty and abdominoplasty, evolved with breast ptosis and lipodystrophy in the upper abdomen. She underwent reverse abdominoplasty using an epigastric dermofat flap for breast projection. The patient had a good postoperative evolution, with satisfactory surgical results. Discussion: Massive weight loss can result in deformities in the breasts and abdomen that require reparative surgery. Breast remodeling is arduous and may require the use of adjacent tissues. Abdominoplasty, in turn, is the most established technique for rejuvenating the trunk; however, when sagging mainly affects the upper abdomen, reverse abdominoplasty becomes an option. In cases where the desire for breast augmentation is associated with excess supraumbilical volume, AMBRA should be considered. Breast augmentation using reverse abdominoplasty proved to be a viable technique in this case, with a satisfactory final result.

RESUMEN

The fruit of Caryocar brasiliense Cambess. is a source of oil with active compounds that are protective to the organism. In our work, we analyzed the physicochemical characteristics and evaluated the effects of supplementation with C. brasiliense oil in an animal model. We characterized the oil by indices of quality and identity, optical techniques of absorption spectroscopy in the UV-Vis region and fluorescence, and thermogravimetry/derived thermogravimetry (TG/DTG). For the animal experiment, we utilized mice (Mus musculus) supplemented with lipidic source in different dosages. The results demonstrated that C. brasiliense oil is an alternative source for human consumption and presents excellent oxidative stability. Primarily, it exhibited oleic MFA (53.56%) and palmitic SFA (37.78%). The oil level of tocopherols and tocotrienols was superior to the carotenoids. The supplementation with C. brasiliense oil reduced the levels of total cholesterol, LDL-c, and non-HDL-c. Regarding visceral fats and adiposity index, the treatment synergically supplemented with olive oil and C. brasiliense oil (OO + CO) obtained the best result. Therefore, C. brasiliense oil is a high quality product for consumption. Its supplementation promotes beneficial effects mainly on the lipidic profile.

RESUMEN

Interest in edible oil extraction processes is growing interest because the final nutritional quality of the extracted oil depends on the procedure used to obtain ir. In this context, a domestic cold oil press machine is a valuable tool that avoids the use of chemicals during oil extraction, in an environmentally friendly way. Although babassu (Attalea speciosa) oil is economically important in several Brazilian regions due to its nutritional and healthy features, few studies have been conducted on the chemical composition and stability of babassu oils extracted by cold pressing. Babassu oil's major constituents are saturated fatty acids (~86.42%), with the most prevalent fatty acids being lauric (~47.40%), myristic (15.64%), and oleic (~11.28%) acids, respectively, within the recommended range by Codex Alimentarius, presenting atherogenicity and thrombogenicity indexes favorable for human consumption. Peroxide value, Rancimat, and TGA/DSC results indicated that babassu oil is stable to oxidation. Also, macro- (Na, K, Ca, Mg, P) and micro-elements (Fe, Mn, Cr, Se, Al, and Zn) of babassu oil were determined, revealing levels below the tolerable upper intake level (ULs) for adults. These findings demonstrated that cold-press extraction using a domestic machine yielded a high-quality oil that kept oil chemical composition stable to oxidation with natural antioxidants.

RESUMEN

BACKGROUND: Fruits present high concentrations of bioactive compounds that are beneficial to health due to their antioxidant properties. New alternatives to vegetable oils with such properties have been studied. We determined the chemical compounds of Byrsonima cydoniifolia A. Juss. fruits in three ripening stages as well as the optical behavior and quality level of the oils. RESULTS: The ripening stage affected the chemical composition of the fruits and oils. The fruits presented high values of bioactive compounds, as ascorbic acid (1.46-1.82 g kg-1 ) and total phenols (3.54-15.91 g gallic acid equivalents kg-1 ), as well as showed excellent antioxidant activity. The ripe fruits showed high content of carotenoids (45.90 mg kg-1 ) were lutein is the major carotenoid, representing 55.56%. The oil of the ripe fruits showed high lipid content (252.6 g kg-1 ) and contained oleic (521.83 g kg-1 ), palmitic (209.13 g kg-1 ) and linoleic (195.4 g kg-1 ) fatty acids. The oil of ripe fruits showed the best oxidative stability, with longer induction period (22.29 h) than the other oils. CONCLUSION: Fruits of B. cydoniifolia A. Juss. demonstrate to possess a promising potential for the use as functional ingredients. The oil of the ripe fruits was more stable and presents a greater potential to be used for edible purposes. © 2018 Society of Chemical Industry.

RESUMEN

Polydextrose (PDX) ingestion may increase the intestinal absorption of iron. This study evaluated the effects of 7.5% polydextrose supplementation on markers of iron uptake, transport and storage in partially gastrectomized rats. Half of a batch of 40 male Wistar rats (250 g) underwent Billroth II partial gastrectomy with anterior truncal vagotomy (GXT), while the other half underwent sham gastrectomy (SHAM). At 7 postoperative days, the animals were subdivided into four groups (n = 10): Sham Control and GXT Control (no polydextrose); Sham PDX and GXT PDX (with 7.5% PDX). The animals were euthanized after 60 day of PDX treatment. Organ weight, cecal pH, the characterization and quantification of short-chain fatty acids (SCFA), hematological parameters, hepatic iron content and the expression of ferroportin (FPT) in the jejunum, cecum, colon and liver were evaluated. PDX caused changes in the cecum of the supplemented animals, where there was a decrease in pH, increase in cecal wall and marked production of SCFA, especially acetic and propionic acids (p < 0.05). Hepatic iron levels were lower in GXT animals. PDX increased hemoglobin (HGB) values by 29.2% and hematocrit (HCT) by 55.8% in the GXT PDX group compared to the GXT Control group. The GXT PDX group had lower hepatic FPT expression (p < 0.05). PDX led to increased SCFA concentration in the supplemented animals. Considering that SCFAs play a central role in the increasing nutrients uptake, this mechanism may be involved in altering the hematology profile observed in these animals but not enough to reverse iron deficiency anemia in post-gastrectomy rats.

RESUMEN

Objetivo: Estudar, respectivamente, as características da população vítima de trauma facial através das variáveis sexo, idade e localização da fratura. Métodos: Estudo retrospectivo por consulta a prontuários de 55 pacientes que estiveram internados na Santa Casa de Santos, no ano de 2006, vítimas de trauma facial. Resultados: Com relação ao sexo, 72,7% dos pacientes eram do sexo masculino e 27,3% do sexo feminino. De acordo com a faixa etária, as fraturas foram assim distribuídas: 0-9 anos: 9,9%; 10-19 anos: 11%; 20-29 anos: 30,7%; 30-39 anos: 19,8%; 40-49 anos: 11%; 50-59 anos: 12,1% e maiores que 60 anos: 5,5%. Quanto à localização, a fratura nasal foi a mais comum com 27,4%, não distante da fratura de zigomático, com 26,4%. A fratura de mandíbula correspondeu a 19,8%, a de maxila a 16,5%, enquanto que a de osso frontal 9,8%. Conclusão: Concluímos que, de acordo com o nosso levantamento, haja vista que a Santa Casa de Misericórdia é a referência para atendimento a politraumatizados da Baixada Santista, que o achado mais comum é o paciente masculino, a 3a. década de vida é a mais acometida e osso mais comumente fraturado é o osso nasal.

RESUMEN

Introdução: A mandíbula é o único osso móvel da face e participa de funções básicas, como mastigação, fonação e deglutição, além de participar da manutenção da oclusão dentária, ocupando juntamente com a maxila a maior porção óssea do esqueleto facial. Devido a sua topografia, anatomia e projeção no terço inferior da face, é freqüentemente atingida por traumas, podendo resultar em fraturas, principalmente em acidentes de trânsito, agressões, queda ou acidentes. As fraturas mandibulares podem levar a deformidades, seja por deslocamentos ou perdas ósseas não-restauradas com alterações de oclusão dentária da articulação temporomandibular (ATM). Quando não identificadas ou tratadas adequadamente, estas lesões podem levar a seqüelas graves, tanto estéticas como funcionais. Relato de caso: JRP, 66 anos, sexo masculino, branco, natural de Itabaiana-BA, procedente de Santos -SP. Paciente vítima de agressão por arma de fogo em abril-07, atendido no pronto socorro da Santa Casa de Santos. No exame físico de entrada, o paciente encontrava-se com vias aéreas pérvias, MV audível bilateralmente, diminuído à direita, taquidispnéico, estável hemodinamicamente, sem sinais de sangramento ativo, Glasgow 15, pupilas isocóricas e fotorreativas, orifícios em região dorsal de hemitórax direito e em mento, disoclusão com acavalgamento de mandíbula direita sobre esquerda, sem lesões de mucosa oral, hematoma em expansão em região cervical direita. Realizado drenagem de hemotórax à direita em sala de emergência e encaminhando paciente para o centro cirúrgico para exploração cervical que revelou lesões vasculares prontamente reparadas. Tomografia de face revelou fratura cominutiva de corpo de mandíbula à direita, sem outras lesões ósseas. Decidiu-se por postergar o tratamento cirúrgico a fim de que houvesse diminuição do edema. Foi submetido a procedimento cirúrgico no 19o. dia de internação, após redução de edema local e alta por parte da cirurgia geral...
