RESUMO

SUMMARY: Orthodontically induced inflammatory root resorption (OIIRR) is a complication of dental treatment which consists of the degradation of local tissue due to an inflammatory reaction provoked by inappropriate orthodontic stimulus. The aim of the present systematic review was to assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontically induced inflammatory root resorption (OIIRR) in animal models. A systematic review was carried out in the MEDLINE, EMBASE and LILACS databases. Studies of interventions in animals were selected which analysed the effect of LLLT on OIIRR repair. The risk of bias was analysed through the 10 domains of the SYRCLE RoB tool for animal studies. Seventy-one studies were found; 27 were eliminated as duplicates and 44 titles/abstracts were analysed. Of these, 38 were excluded, and five studies were included for qualitative analysis. In 66.6 % of the studies included, the authors state that LLLT was effective in the inhibition/repair of OIIRR. In histological analysis it was observed that root resorption was significantly less in animals treated with laser as compared to the control. Furthermore, LLLT accelerated cicatrization after OIIRR. Laser proved effective in reducing root resorption lacunae and shortening the inflammatory process induced by the application of orthodontic force.


RESUMEN: La resorción radicular inflamatoria inducida por tratamiento ortodontico (RRIITO) es una complicación del tratamiento odontológico que consiste en la degradación del tejido local debido a una reacción inflamación provocada por un estímulo ortodóntico inadecuado. El objetivo fue analizar la efectividad de la terapia láser de baja intensidad (LBI) en la disminución de RRIITO en ratas. Se realizó una revisión sistemática en las bases MEDLINE, EMBASE y LILACS. Fueron utilizados los términos 'resorción radicular', 'láser de baja intensidad', 'fototerapia', 'tratamiento ortodóntico', 'movimiento dental'. Fueron seleccionados estudios de intervención en animales, que analizaron el efecto del LBI en la reparación de la RRIITO. Los riesgos de sesgos fueron analizados mediante los 10 domínios de la herramienta SYRCLE RoB para estudios en animales. 71 estudios fueron encontrados, siendo eliminados 27 duplicados, y analizados 44 títulos/abstracts; de estos, fueron incluídos 5 estudios para análisis cualitativa. El 66,6 % de los estudios incluidos afirman que el LBI fue efectivo em reparar la RRIITO. En el análisis histológico se observó que la RRIITO fue significativamente menor en animales tratados con láser en comparación con el control. Además de eso, el LBI aceleró el proceso de cicatrización de la RRIITO. El láser se mostró efectivo en reducir las lagunas de resorción radicular y acortar el proceso inflamatorio inducido por la aplicación de fuerzas ortodonticas.

RESUMO

Media influence may lead adolescents to internalize patterns of physical beauty, resulting in dissatisfaction with their own bodies when they are unable to match up to these patterns. In the constant search for an 'ideal body', adolescents may begin to develop risk behaviors for the development of eating disorders (ED). The object of this study was to analyze the influence of the mass media on body dissatisfaction (BD) and on ED in adolescents, comparing genders. We also analyzed the influence of BD on the risk of developing unsuitable eating behaviors, with risk of ED, comparing genders. A cross-sectional study was carried out with 1011 adolescents: 527 girls and 484 boys. The BMI of each adolescent was determined, and the instruments EAT-26, Sociocultural Attitudes towards Appearance Questionnaire-3 (SATAQ-3), and body shape questionnaire (BSQ), were applied. For statistical analysis, we used Student's t-test, the chi-square test, Pearson's correlation test, the odds ratio, and hierarchical multiple linear regression. The influence of the mass media is associated with a greater probability of adolescents presenting BD. An increase in BD is associated with an increased risk of developing ED in adolescents of both genders but is greater in girls than in boys. Furthermore, the influence of the MM and BMI are predictors of BD in both genders; and BD is a predictor of ED risk in both girls and boys.

RESUMO

BACKGROUND: Analysis of the bones and bone fragments of the cranium may be a useful tool for sex diagnosis in the identification of human remains which have been exposed to adverse conditions. The object of the present study was to evaluate sex prediction through metric and non-metric analysis of the hard palate (HP) and the pyriform aperture (PA), using macerated skulls of adult individuals. MATERIALS AND METHODS: We analysed 312 dry skulls of adult individuals of both sexes, studying the metric and non-metric characteristics of the hard palate and pyriform aperture. The accuracy, sensitivity, specificity and positive and negative predictive values were evaluated. A binary logistic regression and a linear regression were performed. The ROC curve was constructed to analyse the performance of sex diagnosis. Measurements of the HP and the PA were analysed by ANOVA and Tukey's test. The SPSS v.20.0 software was used, with a significance threshold of 5%. RESULTS: The shape of the PA presented 61.9% accuracy, 54.4% sensitivity and 65.7% specificity. The shape of the HP presented 51.5% accuracy, 65.6% sensitivity and 44.7% specificity. Only the height of the PA functioned as a good predictor of sex. CONCLUSIONS: The height of the PA produced good diagnostic performance (area under curve=0.764). The height of the PA was the most reliable indicator for sex prediction, and could be used by forensic scientists to identify sex.

RESUMO

The object of this study was to analyse the morphology and morphometry of the mandibular canal (MC) course and the mental foramen (MF) position in relation to the inferior teeth by panoramic X-ray (PAN). Vertical linear measurements were taken of each hemimandible to obtain the length of the distances analysed. We studied the MF position in relation to inferior premolar roots and the relation between the MC and mandibular teeth roots (MCR). The MF was usually located between the apices of the first and second premolars in younger individuals and immediately below the apex of the inferior second premolar in older individuals. The MC evinced proximity to the third molar, and this relation was not affected by sex or age group. The distances analysed in this study presented a marked difference between gender, with larger values in males than in females. The variations which may occur between individuals and different populations make it essential for dentists and surgeons to plan carefully before procedures involving this region.

RESUMO

OBJECTIVES: To assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontic pain after the application of orthodontic force (OF). METHODS: A systematic search was conducted in the MEDLINE, EMBASE, Scopus, Cochrane Library, Web of Science, and EBSCOhost databases. The study included randomized clinical trials (RCT) which analysed the effectiveness of LLLT in reducing orthodontic pain assessed at 24 and 72 hrs after the application of OF. The risk of bias of the eligible trials was assessed using the Cochrane Collaboration's risk of bias tool. Standard mean difference was calculated and pooled by meta-analysis using random effect models. RESULTS: Of 467 identified articles, 20 RCT were finally included. In the risk of bias assessments, 13 studies presented a high risk, 5 an unclear risk, and 2 a low risk. The meta-analysis showed that in patients treated with laser versus placebo there was a difference in favour of LLLT in spontaneous pain 24 and 72 hrs after the installation of light archwires and spontaneous pain and chewing pain 24 and 72 hrs after the installation of elastomeric separators. CONCLUSIONS: LLLT proved to be effective in promoting a reduction in spontaneous and chewing pain after the application of OF; however, the poor quality of the evidence requires these results to be treated with caution.

RESUMO

Diagnosis and preoperative planning are critical in the execution of any surgical procedure. Panoramic radiography is a routine method used in dentistry to assist clinical diagnosis; however, with this technique 3D anatomical structures are compressed into 2D images, resulting in overlapping of structures which are of interest in the diagnosis. In this study we report the case of a patient who presented with a dentigerous cyst of expressive dimensions in the body of the mandible region. The surgery was planned and executed after observing the margins of the lesion by Cone Beam Computed Tomography (CBCT). We conclude that CBCT is a precise method to help diagnosis; it provides greater accuracy in surgical treatment planning through 3D image display, allowing more effective results.

RESUMO

Fibrous dysplasia (FD) is a condition in which normal bone marrow is replaced by an abnormal proliferation of new fibrous connective tissue. Female patient, white, 20 years old, attended the dental clinic reporting a slow increase in volume in the right mandible region over the last 5 years. She was examined by imaging: the panoramic X-ray revealed a lesion with the appearance of ground glass while the cone-beam computed tomography showed an extensive lesion in the region of the right hemimandible. The histopathological examination was compatible with fibrous dysplasia. Bone gammagraphy was indicated, plus an endocrinological study to eliminate polyostotic forms, which produced a negative result. Monostotic fibrous dysplasia in the right hemimandible was diagnosed. Conservative surgery was carried out and after 1 year recurrence of the tumour was observed. We may conclude that conservative surgery might not be the best choice for treatment for monostotic fibrous dysplasia in the mandible and that other options must be considered, such as radical surgery or the use of bisphosphonates. In our study, we may also conclude that it is very important to explain to the patient the possibility of recurrence of the lesion and the need for monitoring with periodic imaging studies.

RESUMO

The surgery for extraction of the retained lower third molar is one of the most commonly performed procedures in the field of maxillofacial surgery. During this procedure, the surgical trauma can cause damage to the function of muscles involved in mandibular movements, such as the masseter muscle. In order to accelerate post-surgical recovery, many physiotherapy resources are employed, including laser therapy. The aim was to analyze the electrical activity of the masseter muscle treated with Low-level Laser (LLL) after surgical trauma. Assessments of masseter muscle on a sample of 60 patients were performed by surface electromyography in four instances: immediate preoperative, postoperative at 7, 14 and 21 days. The patients were divided into two groups: 1- untreated group with LLL in the postoperative; 2- group treated with LLL (810 nm; 10 J/cm2) in the immediate postoperative and at 3, 6 and 9 days after surgery. On the seventh day after surgery 23.3 % of the patients in the group receiving LLL showed recovery of their muscle activity as they presented in the immediate preoperative, versus only 3.3 % of the untreated group. On the 14th day, 73.3% of treated patients showed functional rehabilitation, versus 6.7% in the untreated group, and on the 21st, 80% versus 10% in the untreated group. On the 14th postoperative day the electrical activity of the masseter muscle treated with LLL after surgical trauma was compatible with a condition of complete functional recovery. The findings of this electromyographic study indicated that LLL proved to be an efficient physiotherapeutic method for stimulating the masseter muscle functional recovery after surgery of retained lower third molars.


La cirugía para extracción del tercer molar mandibular retenido es uno de los procedimientos más realizados en el campo de la cirugía maxilofacial. Durante este procedimiento, el trauma quirúrgico puede causar daño a la función de los músculos involucrados en los movimientos mandibulares, entre ellos el músculo masetero. Con el objetivo de acelerar la recuperación postoperatoria, son utilizados muchos recursos de fisioterapia, incluyendo la terapia con láser. El objetivo de este estudio fue analizar la actividad eléctrica del músculo masetero tratado con láser de baja intensidad (LBI) después del trauma quirúrgico. Se realizaron evaluaciones del músculo masetero en una muestra de 60 pacientes, a través de electromiografía de superficie en cuatro momentos: preoperatorio inmediato, postoperatorio a los 7, 14 y 21 días. Los pacientes fueron divididos en dos grupos: 1 - grupo no tratado con LBI en el postoperatorio; 2 - grupo tratado con LBI (810 nm; 10 J/cm2) en el postoperatorio inmediato y a los 3, 6 y 9 días tras cirugía. Al séptimo día tras cirugía el 23,3 % de los pacientes del grupo tratado con LBI presentaron recuperación de su actividad muscular equivalente a lo presentado en el preoperatorio inmediato, frente a sólo el 3,3 % del grupo no tratado. En el día 14, el 73,3% de los pacientes tratados presentaron rehabilitación funcional, frente al 6,7% del grupo no tratado y en el vigésimo primer día, el 80% frente al 10% del grupo no tratado. En el dia 14 postoperatorio la actividad eléctrica del músculo masetero tratado con LBI después del trauma quirúrgico fue compatible con una condición de recuperación funcional completa. Los hallazgos de este estudio electromiográfico indicaron que el LBI es un eficiente método fisioterápico para estimular la recuperación funcional del músculo masetero tras cirugía de terceros molares mandibulares retenidos.

RESUMO

The lingula of the mandible is a bone projection that limits medially the mandibular foramen, which is the region where the inferior alveolar neurovascular bundle penetrates. The lingula is an important anatomical landmark used in maxillofacial surgeries and to block the inferior alveolar nerve. The aim of this study was to analyze the different types of lingula found in mandibles of Brazilian individuals, considering aspects such as gender and race. One hundred thirty-two macerated mandibles of Brazilian adult individuals of both sexes, black and white skin colors, were used. The lingula was classified into four types: triangular, truncated, nodular and assimilated. The data were analyzed using Chi-square test and Fisher's exact test. The truncated shape was the most commonly found (49 %), followed by nodular (26.5 %) and triangular (23.3 %) shapes. The assimilated shape was significantly less prevalent with 1.2 %. Each type of the lingula was more often bilateral rather than unilateral. Considering skin color we observed that the truncated shape was more prevalent in black individuals than in white individuals and the nodular shape was more prevalent in white individuals than in black individuals. There was no case of assimilated shape in black individuals. Considering gender we observed that the truncated shape was more prevalent in females than in males and the triangular shape was more prevalent in males than in females. The lingula shape showed no side preference. Our findings facilitate the planning of oral and maxillofacial surgical procedures that involve the lingula and/or the inferior alveolar neurovascular bundle, avoiding operative complications.


La língula de la mandíbula es una proyección ósea que limita medialmente el foramen mandibular, región en la cual penetra el fascículo vásculonervioso. Es un importante punto de referencia en cirugías maxilofaciales, utilizado en cirugías y en el bloqueo del nervio alveolar inferior. El objetivo fue analizar los diferentes tipos de língula encontrados en mandíbulas de individuos brasileños, considerándose aspectos como sexo y raza. Fueron utilizadas 132 mandíbulas maceradas de individuos brasileños adultos de ambos sexos, leucodermas y melanodermas. Se clasificó la língula en cuatro tipos: triangular, truncada, nodular y asimilada. Para el análisis estadístico se utilizó el Chi-cuadrado y la prueba exacta de Fisher. La forma truncada fue la más frecuente (49 %), seguida de la nodular (26,5 %) y triangular (23,3 %). La forma asimilada fue menos prevalente, con el 1,2%. Cada tipo de língula fue más común bilateral. Considerando el color de piel se observó que la forma truncada fue más prevalente en melanodermas que en leucodermas y la forma nodular fue más prevalente en leucodermas que en melanodermas. No se encontró la forma asimilada en individuos melanodermas. Considerando el sexo, se observó que la forma truncada fue más frecuente en mujeres que en hombres y la forma triangular más frecuente en hombres que en mujeres. La forma de la língula mostró no tener preferencia por lado. Nuestros hallazgos facilitan la planificación de los procedimientos quirúrgicos orales y maxilofaciales que implican la língula y/o el paquete neurovascular alveolar inferior, evitando complicaciones operatorias.

RESUMO

En la literatura científica los efectos adversos del láser de baja intensidad (LBI) no están descritos de forma precisa, tampoco su inocuidad. El objetivo de este estudio fue evaluar el efecto de distintas dosis de LBI en el cóndilo mandibular de conejos. Dieciséis conejos divididos aleatoriamente en cuatro grupos experimentales (GE) de 4 animales fueron utilizados en este estudio. Se realizó un examen de tomografía computarizada cone beam (TCCB) de ambas articulaciones temporomandibulares (ATMs) de todos los animales que fueron utilizadas como control (GC). Luego, irradiamos cada ATM con LBI (As-Ga-Al 904 nm), 100 mW, spot 0,2 cm2, dos puntos, 3 veces/semana, totalizando 10 veces, con dosis de 15 J/cm2 (GE-1), 45 J/cm2 (GE-2), 60 J/ cm2 (GE-3) y 90 J/cm2 (GE-4). Después de 20 días de la última irradiación se realizó un nuevo examen de TCCB y luego se obtuvo las mediciones de los cóndilos en los planos coronal y sagital. Para el análisis estadístico se utilizó las pruebas de ANOVA y t-student. Los valores promedios encontrados para el GE fueron mayores que los encontrados para el GC, en los planos coronal y sagital. Hubo diferencia estadística significativa para el grupo 1 y entre los grupos 1 y 2. Concluimos que los valores promedios encontrados en las mediciones de los cóndilos mandibulares, sometidos a las dosis de LBI utilizadas en este estudio, fueron mayores que los encontrados para el GC en los planos coronal y sagital. Además, la TCCB demostró ser un método eficaz para el análisis de las dimensiones condilares.


In the scientific literature the adverse effects of Low Level Laser (LLL) are not precisely described, neither is their safety. The aim of this study was to evaluate the effect of different protocol doses of laser on the mandibular condyle of rabbits. Sixteen rabbits randomly divided into four experimental groups (EG) of 4 animals were used in this study. We carried out a cone beam computed tomography (CBCT) examination of both temporomandibular joints (TMJs) of all animals which were used as control. Subsequently, we radiated each TMJ with LLL (Ga-Al-As 904 nm), 100mW, spot 0.2 cm2, two points, 3 times/week, totaling 10 times, with doses of 15 J/cm2 (EG-1), 45 J/cm2 (EG-2), 60 J/cm2 (EG-3) and 90 J/cm2 (EG-4). After 20 days of the last irradiation we performed a new CBCT exam and then the measurement of the condyles on the coronal and sagittal planes was obtained. In the analysis of the results ANOVA and t-student for correlated samples was used. The average values found for the EG were higher than those found for CG for both the coronal and sagittal planes. There was a significant statistical difference for group 1 and between the groups 1 and 2. We concluded that the average values found in the measurements of the mandibular condyles, submitted to doses of LLL used in this study, were higher than those found for the control group in both the coronal and sagittal planes. Furthermore, the CBCT proved to be an effective method for analysis of condylar dimensions.

RESUMO

OBJECTIVES: The purpose of this research was to study, in macerated adult human mandibles, the height of the lingula and provide morphometric data for its location considering aspects such as shape of the lingula, gender, and race. MATERIAL AND METHODS: 132 macerated mandibles of Brazilian adult individuals, both sexes, Amerindian and Caucasian, were used. The distances: from mandibular notch to lingula; from anterior margin of ramus of mandible to lingula; from posterior margin of ramus of mandible to lingula; from mandibular base to lingula, and the height of lingula were obtained. To perform these measurements we used a digital caliper. The variables such as gender and race were analyzed. RESULTS: The mean values found for the height of lingula and its location were determined according to the gender, race, and the lingula shape. CONCLUSION: This research provides additional data on height of the lingula and morphometric data for its location considering aspects such as shape of the lingula, gender, and race, information that had not been reported in the literature to date. We emphasize that a careful study considering gender and ethnic group makes procedures involving the region of lingula safer.

RESUMO

PURPOSE: The aim of this study was to provide morphometric data, obtained from macerated mandibles, which might facilitate the topographic location of the mandibular foramen, considering aspects such as gender, age and ethnicity. MATERIALS AND METHODS: One hundred and eighty-five macerated mandibles of adult black and white individuals of both sexes were analyzed. Initially, 5 points were established: MF, the lowest point of the mandibular foramen; S, greatest concavity of the mandibular notch; A, anterior margin of the ramus of mandible; P, posterior margin of the ramus of mandible; and Go, gonion. Then the following measurements were performed bilaterally: MF-S, MF-A, MF-P and MF-Go. RESULTS: The following mean values were found: MF-S: 21.02 mm for white females (WF) and 22.00 mm for black females (BF); 24.40 mm for white males (WM) and 24.35 mm for black males (BM); MF-A: 17.05 mm for WF and 18.09 mm for BF; 17.18 mm for WM and 18.11 mm for BM; MF-P: 11.11 mm for WF and 12.24 mm for BF; 13.10 mm for WM and 14.15 mm for BM; MF-Go: 19.00 mm for WF and 19.44 mm for BF; 23.13 mm for WM and 22.12 mm for BM. CONCLUSIONS: The values found in this study, considering gender, age and ethnic group, can be used as a parameter to carry out the sagittal split ramus osteotomy technique, making it more predictable and with less risk of complications.

RESUMO

La displasia ectodérmica hipohidrótica (DEH) es una enfermedad rara de etiología genética. La forma más frecuente es la de herencia recesiva relacionada al cromosomo X con sujetos de sexo masculino afectados y de sexo femenino portadores. Pueden ocurrir a través de mutaciones autosómicas, y en estas, las del gene EDA1 son responsables por la mayoría de los casos. Se caracteriza por la tríada: hipohidrosis, oligodoncia e hipotricosis. Presentamos dos casos de pacientes con DEH en los cuales se observaron signos característicos del síndrome: piel delicada; cabellos, cejas y pestañas escasos; arrugas periorbitales; hiperpigmentación perioral y periorbital; labios prominentes y además de eso el paciente del caso 2 presentaba depresión del puente nasal. Se constató aún disminución de la secreción salival y lagrimal y hipoplasia de maxila en los dos casos. Al examen oral estaban presentes en el caso 1 los caninos superiores derecho e izquierdo temporales y el canino inferior derecho temporal y en el caso 2 los caninos superiores e inferiores (derechos e izquierdos) temporales y dos incisivos superiores (uno derecho y otro izquierdo) permanentes con morfología alterada, siendo todos los elementos dentarios íntegros. El tratamiento odontológico precoz de los portadores de DEH, principalmente en la presencia de oligodoncia, como la que se observa en los casos aquí reportados, es importante no solamente para ofrecer mejor calidad de vida para estos pacientes en corto plazo, sino también en el intento de mitigar las alteraciones en el crecimiento facial a que estos pacientes están sometidos.


Hypohidrotic ectodermal dysplasia (HED) is a rare disease of genetic etiology. The most frequent form is of recessive linked to X-chromosome inheritance with affected male and female carriers. It can occur through autosomal mutations, of the gene EDA1 gene being responsible for the majority of the cases. It is characterized by the triad: hypohidrosis, oligodontia and hypotrichosis. We present two cases of patients with HED in which we observed characteristic signs of this syndrome: delicate skin, sparce hair, eyebrows and eyelashes, periorbital wrinkles, perioral and periorbital hyperpigmentation, prominent lips, in addition the patient in case 2 also present the depressed nasal bridge. We also found decreased salivary and lacrimal secretion and maxillary hypoplasia in both cases. At the oral examination in case 1 the upper right and left deciduous canines and lower right deciduous canine were present, and in case 2 the upper and lower (right and left) deciduous canines and two upper (one right and other left) permanent incisors were present with altered morphology, all of these dental elements were healthy. The early dental treatment of patients with HED, especially in the presence of oligodontia, as observed in our cases, is important not only to provide a better quality of life for these patients in the short term, but also an attempt to minimize the changes in facial growth to which these patients are subject.

RESUMO

The discomaleollar ligament is not described in the anatomy textbooks but was demonstrated by Pinto (1962) and others. It is a ligamentous structure connecting the malleus in the tympanic cavity and the articular disc and the capsule of the temporomandibular joint. This anatomical relationship between the middle ear and temporomandibular joint is supposed to be one of the explanations for the otological symptons associated with temporomandibular joint dysfunction. The aim of our study was to determine the frequency of occurence of the discomaleollar ligament. Twenty hemi-heads of adults human were carefully dissected from a superior approach through the middle cranial fossa. The bone of the middle cranial fossa over the temporomandibular joint region and the roof of the tympanic cavity were carefully removed to expose the articular disc, ossicles of the middle ear, lateral pterygoid muscle and other structures in the region. The discomalleolar ligament was found in all studied cases what allow us to suggest that it is an intrinsic ligament of the temporomandibular joint.


El ligamento discomaleolar no se describe en los textos de anatomía, pero ha sido demostrado por Pinto (1962) y otros. Es una estructura ligamentosa que conecta el maléolo en la cavidad timpánica con el disco articular y la cápsula de la articulación temporomandibular. Esta relación anatómica entre el oído medio y la articulación temporomandibular se supone que es una de las explicaciones de los síntomas otológicos asociados a la disfunción temporomandibular. El objetivo de nuestro estudio fue determinar la frecuencia de aparición del ligamento discomaleolar. Veinte hemi-cabezas de individuos adultos fueron cuidadosamente disecadas desde un acceso superior a través de la fosa craneal media. Se retiró el hueso de la fosa craneal media sobre la región de la articulación temporomandibular y el techo de la cavidad timpánica, para exponer el disco articular, osículos del oído medio, músculo pterigoideo lateral y otras estructuras en la región. El ligamento discomaleolar se encontró en todos los casos estudiados, lo que nos permite sugerir que es un ligamento intrínseco de la articulación temporomandibular.

RESUMO

As úlceras por pressão, em estágios mais avançados, podem apresentar infecção, retardando a cicatrização e podendo ser letal. Entre os agentes infecciosos estão as pseudomonas, que são patógenos oportunistas e ubíquos. Objetivou-se verificar a eficácia do uso de açúcar refinado no tratamento de infecção por Pseudomonas sp em úlcera por pressão. Foi realizado um estudo de caso com paciente do sexo feminino, 79 anos, em internação domiciliar, na cidade de São Paulo, em 2006, com úlcera por pressão contaminada por Pseudomonas saprophaga/saprófitas (sp). A lesão era lavada com soro fisiológico 0,9% e depois coberta com uma camada de açúcar refinado, até não se visualizar mais o leito da mesma. Em seguida, era ocluída com gaze estéril e micropore. A troca do curativo era realizada de 6 em 6 horas. O exame de cultura da lesão, após 72 horas de tratamento, mostrou ausência do microorganismo, o que se conclui que o tratamento foi eficaz.


Pressure ulcers are lesions located in regions where the skin suffers prolonged pressure. At more advanced stages, they can present infections that not only delay cicatrisation but can be fatal. Among the infectious agents are the Pseudomonas, which are ubiquitous opportunistic pathogens. In 2006 a case study was conducted of a 79 year old female patient under home care to determine the effectiveness of using refined sugar to treat Pseudomonas saprophaga (sp) infection of pressure ulcer. The lesion was washed with 0.9% sterile saline solution and then covered with a layer of white sugar until the wound bed was not longer visible and then dressed with sterile gauze and micropore tape. The dressing was changed every 6 hours. Culture from the wound examined after 72 hours of treatment was free of Pseudomonas sp., warranting the conclusion that the treatment was effective.

RESUMO

As úlceras por pressão, em estágios mais avançados, podem apresentar infecção, retardando a cicatrização e podendo ser letal. Entre os agentes infecciosos estão as pseudomonas, que são patógenos oportunistas e ubíquos. Objetivou-se verificar a eficácia do uso de açúcar refinado no tratamento de infecção por Pseudomonas sp em úlcera por pressão. Foi realizado um estudo de caso com paciente do sexo feminino, 79 anos, em internação domiciliar, na cidade de São Paulo, em 2006, com úlcera por pressão contaminada por Pseudomonas saprophaga/saprófitas (sp). A lesão era lavada com soro fisiológico 0,9% e depois coberta com uma camada de açúcar refinado, até não se visualizar mais o leito da mesma. Em seguida, era ocluída com gaze estéril e micropore. A troca do curativo era realizada de 6 em 6 horas. O exame de cultura da lesão, após 72 horas de tratamento, mostrou ausência do microorganismo, o que se conclui que o tratamento foi eficaz.(AU)
