Summary: The Plastic surgery is a branch of surgery that deals with the surgical correction of congenital whole process, acquired, or simply involutional tumor, which requires repair or replacement of anatomical structures, which affect the body form and function, its techniques are based in transplantation and tissue mobilization. Coverage of skin defects implies therefore transposing tejidos.El vasospasm is a common complication in surgeries involving transfers distance tissue or interventions reimplantes, and in such flaps this complication may lead to the total loss of tissue transferred . Recent studies suggest that vasospasm may be due to endothelial dysfunction, whose precise cause remains unknown. Under normal conditions there is a fine balance between substances constrictoras (free radicals, endothelin, thromboxane A2 ..) and vasodilator (nitric oxide, PG, etc.), which maintains vascular tone. Probably injury ischemia is due to the breakdown of this delicate balance of vascular regulation, rather than a single change. In this thesis are achieved key objectives. A) Identification of the role of NO in injury ischemia. B) Discovery of the drug most effective way to act on its synthesis in the interests of the survival of the flap.

Summary: There will always be a study on the effectiveness of meperidine by thoracic epidural associated with general anesthesia during the intraoperative of patients who undergo surgical resection of lung parenchyma, compared with two other anesthetic techniques (thoracic epidural bupivacaine with general anesthesia and with general anesthesia). Intraoperatoriamente compared oxygenation and shunt intrapulmonar during ventilation unimpulmonar among the three groups anestésicos.También compared morbidity related to the type of anesthetic technique and mortality in the first 30 días.La meperidine not epidural affected venous or arterial oxygenation nor intrapulmonar shunt during one lung ventilation, as compared with anesthesia general.La morbidity (postoperative pulmonary complications, heart and kidney) was similar among the three grupos.La mortality in the first 30 day was lower in patients who had received an epidural block with bupivacaine or meperidian that in the anestesioa general, although the differences were not statistically significativas.Se concludes that meperidine administered through an epidural anesthesia is generally associated with the technique of anesthetic election to the CRPP in those cases in which the administration of local anesthetics through epidural was contraindicated.

Summary: The child receives fluoride by very different routes: the beverage, food, brushing teeth, and through other preventive guidelines as mouthwashes, gels, varnishes, etc.. Part of this fluorine will be swallowed and systemic routes, where its effectiveness is greatly reduced. Most of swallowing fluoride will be eliminated in the urine. The pH of urine affects significantly the rate of excretion. OBJECTIVES Rate urinary excretion of fluoride in children and establish relationships with the amount of toothpaste used. MATERIALS AND METHODS We conducted a prospective study of 115 school children between 5 and 8 years. 15 acted as a control group. We calculated the number of passes used dental each child and studied rates of fluoride enorina before and after brushing with toothpaste flourado. To assess the urinary excretion used in the ratio of fluorine mg / g creatinine (fluorine corrected), and discussed the relationship with the quantity of paste used and the pH of the urine depending on age. The statistical treatment was performed using non - parametric tests. RESULTS The average toothpaste used by the child was 1192 mg (DT = 421). The average fluoride corrected at the first take was 0.59 mg / g (0.49) and the second taking of 1.14 mg / g (DT = 0.91). The Wilcoxon test to assess the difference between these values resulted in a significacíon statistical P less 0001. CONCLUSION The population of our study uses a number of pulp dentífica above the levels recommended for children of those ages and sniños of 7-8 years used significantly more than those of 5-6 years. Following a tooth brushing occurs umento the levels of fluoride in urine, well above their baseline rallies. The pH of acid urine favors tubular reabsorption of fluorine and diminishes its excretion.

Summary: Some authors have found with the metodologÃÂa Doppler that corcocentesis produces a vasodilataciÃÂ charges in the umbilical artery and cerebral artery mean fetus. This paper attempts to investigate the origin of these modifications hemodinÃÂ ¡micas is related to two hormones related to stress "the beta-endorfina and cortisol. It could analyze cordocentesis of 21 couples normal madre-feto. Our data confirm that cordocentesis causes a vasodilataciÃÂ charges in the umbilical artery and half fetal cerebral artery. Our data suggest that cordocentesis produces a hormonal response compatible with a fetal stress, increasing both the fetal cortisol and the beta-endorfina fetal, but not claim that the changes hemodinÃÂ ¡monkeys observed in the fetus during cordocentesis be changes in concentrations plasmÃÂ ¡cies fetal cortisol and beta-endorfina. Nor have we found a correlaciÃÂ charges between these changes hemodinÃÂ ¡monkeys in the fetus and concentrations plasmÃÂ ¡cies maternal cortisol and beta-endorfina.

Summary: Hepatocellular carcinoma introduced 5ÃÂ eighth malignant tumor mÃÂ ¡s common man and the 8ÃÂ sixth in women. EspaÃÂ ± a is a paÃÂs incidence intermediate (6-8 casos/10000 room and aÃÂ ± o). We analyzed a series of 165 patients divided into two groups: Group A (93) of patients with resecciÃÂ ³ n partial. Group B (71) of transplant patients. We analyze factors pronÃÂ ³ sticos recurrence, survival and disease-free survival. RESULTS In Group A the incidence of relapse was 62.1% with an actuarial survival at 1.3 and 5 aÃÂ ± os of 81.4%, 48.8% and 34.6% respectively, with disease-free survival of 66.8%, 28.8% and 18.3%. These are factors pronÃÂ ³ stico in this group: age less than 55 aÃÂ ± os, AFP greater than 200 ng / ml transfusiÃÂ charges of hematÃÂes, tamaÃÂ ± or greater than 5 cm, invasiÃÂ ³ n vascular satelitosis, degree of difernciaciÃÂ ³ n moderate or poor, stage IV and lower margin of 1 cm. In group B, the incidence of tumor recurrence is 19% superviencia to 1.3 and 5 aÃÂ ± os of 79.4%, 61% and 50.3%. These are factors pronÃÂ ³ stico an AFP greater than 200 ng / ml mÃÂ ¡s, 3 nÃÂ ³ dulos, tamaÃÂ ± or greater than 5 cm, invasiÃÂ ³ n vascular satelitosis, afectaciÃÂ ³ n bilateral degree of diferenciaciÃÂ ³ n moderate or poor and IV Stadium. Comparing the two groups transplantation hepÃÂ ¡tico offers greater survival and less recidifva that resecciÃÂ ³ n partial except in patients cort etiologÃÂa with HBV, with tumors larger than 5 cm, bilateral degree of diferenciaciÃÂ ³ n moderate or poor with invasciÃÂ ³ n vascular satelitosis or state advanced. CONCLUSIONS transplant hepÃÂ ¡tico offers greater possibilities curaciÃÂ charges that resecciÃÂ ³ n partial to a patient with hepatocellular carcinoma, with the lowest incidence of tumor recurrence. Not beneficiarÃÂan patients with a tumor larger than 5 cm, bilaterally, with satelitosis with invasiÃÂ ³ n vascular, with a degree of diferenciaciÃÂ ³ n moderate or poor or a estadÃÂo advanced. In patients with a solitary tumor less than 5 cm or less than 3 nÃÂ ³ dulos smaller than 3 cm estÃÂ I indicated transplantation hepÃÂ ¡tico. In patients with good funciÃÂ ³ n hepÃÂ ¡tica and with a tumor perifÃÂ © rich less than 3 cm estarÃÂa justified resecciÃÂ ³ n partial, but limited by a margin greater than 1 cm and avoiding transfusiÃÂ charges of hematÃÂes. We have demonstrated the efficacy of quimioembolizaicÃÂ charges during the transplant waiting list. A level AIA higher than 200 ng / mL is associated with incidence of tumor recurrence.

Summary: Lasers have been used in oral surgery for many years, although the arrival of new systems and wavelengths has encouraged its implementation in other areas of the odontostomatology as implantology. The last few lines of ivnestigación have been aimed at their applicability for the sterilization of implant surfaces in cases of diseases periimplantarias. OBJECTIVES 1, Exploring the qualitative and quantitative changes after irradiation with lasers CO2, Er: YAG and diode on different surfaces of implants by scanning electron microscopy and spectroscopy scattering energy X-ray 2-Define the powers most appropriate for each type of laser, which have no adverse effects on the surfaces of implants studied. 3-To examine the effect of sterilizing the three lasers on these surfaces contaminated implants in a culture medium for bacteria periodontopatógenas (Actinobacillus actinomycetemcomitans, and Porfiromona gingivalis Prevotella intermedia). MATERIALS AND METHODS have been used 63 implants divided into three groups of 21 implants each depending on the type of surface treatment: hidroxiapatia (HA), arenados (MBR) and grabados-pasivados (TSA). We used three laser systems: CO2a 5 and 8W power Er: YAG at 150 and 350 mJ, and diode-5 and 10W. For obseración of implants used a scanning electron microscope model JEOL JSM 6400 that includes a spectrometer Oxford model INCA. The material microbiological employee were strains A.actinomycetemcoimtans incubated in the middle Dentaid-1 selective, and strains P.intermedia and P.gingivalis incubated in the medium generally agar-sangre. For fastening of the samples was used glutaraldehyde to 25% monosodium phosphate and sodium hydroxide to 2.26%, distilled water and ketones several percentages. The methodology consisted of the following steps: Irradiation of the implants, and study with SEM spectrometry, identifying the ideal power, incubation in culture media, irradiation implants contaminated reincubación, preparation of the samples and study with SEM, and processing statistical data (Student's t and CHI-CUADRADO). FINDINGS AND CONCLUSIONS Irradiation of the implants with powers of 5W with CO2 laser, 150 mJ laser Er: YAG, and 5W laser diode has not produced qualitative or quantitative changes on implants surface arenadas (MBR) and recorded - pasivadas (TSA). The implementation of the three types of laser on hydroxyapatite implants has led to significant alterations surface, it must be tightened up the precuaciones and limit the time of irradiation. The increased powers it produced alterations in the three types of surface. When irradiaron implants contaminated, only laser diode to 5W power got inhibit the growth of the three gérmines studied. The CO2 laser to 5W only inhibited the growth of P.intermedia, while the laser Er: YAG at 150 mJ did not inhibit the growth of any of the three germ. The laser diode to 5W power can make a therapeutic alternative in the treatment of diseases periimplantarias because, it inhibit the growth of the main periodontal pathogens without producing alterations surface.

Summary: INTRODUCTION The failure to adjust liabilities undertakes the functioning of the prosthesis on biomechanical implants, constituting one of the main causes of failure. OBJECTIVES To quantify the mismatch vertical structures on pillars coladas Cemented prefabricated dental implants and evaluate whether there are differences in the vertical divergence depending on the alloy design and the strained evaluated. MATERIALS AND METHODS In our research work "in vitro" starting from the use of a metal support pillars that look prefabricated implant cement, in order to waxing and then straining 90 metal structures, choosing to do so three different alloys (cobalt - chrome, titanium and paladio-oro) and two designs (strained for individual crowns and bridges three pieces póntico intermediate). Subsequently cementamos the strained to the pillars and take a series of measures mismatch vertically along the contour marginal test tubes with a MEB, establishing measurements vertically between the edge superio margin pillar and the lower edge of the margin of the structure. Finally, we compared statistically results obtendios by evidence not Paramétricas. RESULTS As for the aleacióm, the group cobalto-cromo is offering perores vertical adjustment values, with statistically significant differences regarding the two other alloys. In response to the design, we found no statistically significant differences between the individual strained and strained to bridges. Only the 93% confidence are significant differences entrelos Casting unit and bridges analyzing this issue within the group structure of titanium, with the worst value adjustment to the strained for bridges. Considering the unit structures, the group cobalto-cromo significant differences with regard to the two other alloys, which remain the worst vertical adjustment provides. Finally, within the structures for bridges, only found significant differences with a confidence level of 90% between cobalto-cromo and paladio-oro. DISCUSSION Our results are consistent with values reported by most authors consulted in studies "in vitro" fixed cemented prosthesis inside and implantosoportada. CONCLUSIONS 1 - The group Casting cobalto-cromo is showing greater respect to the vertical discrepancies Casting paladio-oro and titanium, both in terms of the unit as strained structures castings for the bridges. 2 - There were no significant differences between the vertical adjustment of the group Casting paladio-oro and titanium in the case studies. 3-Comparing the structures castings unit with the structures for bridges coladas regardless of the alloy, we found no significant differences with respect to vertical adjustment. 4-Within each alloy, the contrast with the strained unit Casting for bridges only found significant differences (at 90% confidence) in the group of titanium, in which strained unit offered better vertical adjustment that strained for bridges . 5, - Our results are comparable to those of experiments in vitro made similar conventional fixed prosthesis.

Summary: The proposed study is a clinical intervention study for this prospective longitudinal comparative between two poblaciónes individuals affected periodontitiscrónica widespread moderate to respond to the following questions: Do you conventional periodontal treatment is just as effective in type 2 diabetic patients than in subjects healthy? Â Does that periodontal treatment effect on metabolic control in diabetic individuals? The first objective is to assess the efficacy of treatment periodontal not querúrgico locally, ie assessing the clinical and immunological response of tissues perirodontales to demonstrate an improvement in signs and symptoms associated with the disease periodontal.Como second objective seeks to assess the effect of periodontal treatment on metabolic control valuing the metabolic response by identifying the basal glucose and the value of HbA1c. The main finding of the study support the hypothesis that periodontal disease is a risk factor for diabetes indicating that the elimination of periodontal infection in patients with type 2 diabetes not only leads to an improvement in their condition periodontal but colleva improvement their metabolic control.

Summary: The periapical surgery is a surgical technique that takes place in the tissues as periapical apical's own tooth to achieve the sealing of the root canal and cleaning of the affected tissue. Thus began investigating the possibility of using laser Er: YAG in this field OBJECTIVES 1-check the sterilizing effect of laser Er: YAG teeth into in vitro with different powers of enforcement. 2-Corroborar said sterilizing effect in granulomatosas periapical lesions through microbiological checks. 3-Monitor the evolution of periapical lesions, through clinical and radiographic controls. MATERIALS AND METHODS In the first phase of the investigation were used 47 teeth unirradiculares They were divided into three groups of laser irradiation and a control group. Once irradiated teeth were introduced in the middle of enrichment under anaerobic conditions and during 74 hours, conducted visual inspections to verify the presence of turbidity (bacterial growth) or transparency in that medium. Subsequently microbiological checks were conducted to validate the results of the visual controls. In the second phase or clinical study involving 45 patients susceptible periapical surgery to be performed this treatment, microbiological samples taken before and after laser irradiation RE: YAG. Subsequently evolutionary checks were conducted to 3,6,12,24 months clinical and radiographic, controlling the remodeling of the bone cavity. RESULTS The results of this in vitro study showed a clear decrease in the growth of bacteria in the teeth irradiated with laser Er: YAG, as we increase the power of implementation. In the clinical study showed a clear decrease in microorganisms after the laser treatment, essentially: P.gingivlis, T.forsythensis, F.nucleatum and P.intermedia. As for the clinical development, the results obtendios show a success of 95.8% at 24 months and 77.7% had incomplete ossification, introducing a statistically significant relationship (p less 0.01) between the degree of ossification and the presence of microorganisms after treatment.

Summary: The reconstructive surgery is one of the most important paragraphs in maxillofacial surgery because of the legacy that originates at aesthetic and funcional.El menejo of patients with head and neck tumors, especially advanced tumors, continues to pose a reto.El goal in the modern treatment of cancer is to achieve the maximum survival with a minimal loss of quality vida.La reconstruction requires the achievement of oral competition, effectively chewing, swallowing functional conservation speech and an acceptable appearance estética.Uno of progress major surgery for head and neck reconstruction was the emergence of genetic flaps miocutáneos pediculados, which would solucionear some of the problems of skin flaps (arc of rotation, limited extension, necrosis distal). With the development of colggajos miocutáneos , it was possible to transfer at a greater distance and secure manner, large quantities of well-vascularized tissue increased the therapeutic arsenal available, allowing the transport of vascularized tissue even further and more specific. While today represent the most refianda techniques for reconstruction, reflecting an increased surgical time, require more technical requirements and sonmás costosos.El goal is to make a review and update of the medical literature and our experience with regard to a range of 8 flaps, with the idea of demonstrating that the flaps pediculados offer a safe, quick and with little morbidity, which allows great versatility in the reconstruction.
