ABSTRACT

El cuerpo adiposo de la boca (CAB) es un componente adiposo multilobulado bien delimitado, localizado de manera bilateral en la región facial íntimamente relacionado a estructuras nerviosas y vasculares. La remoción de CAB es un procedimiento ampliamente estudiado en el campo de la cirugía maxilofacial, utilizado principalmente para cubrir defectos. Su influencia en la estética facial ha iniciado una popularización de la remoción de la extensión bucal de CAB para obtener un rostro más estilizado, intervención difundida como poco invasiva y sin complicaciones. El objetivo de este estudio fue recopilar y evaluar estudios que reporten y evalúen complicaciones asociadas a la remoción por razones estéticas de CAB. Se revisó la evidencia en las bases de datos Medline vía PubMed, Epistemonikos, Scopus y Google Scholar, utilizando términos predefinidos, seleccionando estudios primarios de reportes de casos. Se incluyeron 7 artículos con un total de 10 pacientes; de estos, ocho pacientes se realizaron este procedimiento en Brasil, uno en Estados Unidos y uno en Chile. La distribución de la población fue de 3:7 entre hombres y mujeres con edad promedio de 35 años y un rango entre los 23 a los 49 años. En relación a las complicaciones reportadas, 100 % de los pacientes presentaron asimetría facial, un 80 % presentó edema facial, 30 % manifestaron sialocele, Trismus 20 %, 40 % presentó hematoma, 20 % compromiso del estado general, 20 % presentaron disfagia, en los casos de hipoestesia, parestesia, absceso, seroma, parálisis facial, odinofagia, fiebre se expresaron en 10 % de la población estudiada. En todos los estudios se describió una reintervención quirúrgica posterior a la remoción estética del cuerpo adiposo de bichat. La escasa literatura y la baja calidad de esta, no permite estimar el porcentaje real de posibles complicaciones, tampoco es posible determinar sus resultados a largo plazo ya que no existe en la evidencia un seguimiento apropiado para estos pacientes.


The buccal adipose body (BAB) is a well- defined multilobulated adipose component, located bilaterally in the facial region, closely related to nervous and vascular structures. BAB removal is a widely studied procedure in the field of maxillofacial surgery, used mainly to cover defects. Its influence on facial aesthetics has started to popularize the removal of the BAB buccal extension to obtain a more stylized face, an intervention widely known as minimally invasive and without complications. The objective of this study was to collect and evaluate studies that report and evaluate complications associated with the removal of BAB for cosmetic reasons. The evidence was reviewed in the Medline databases via PubMed, Epistemonikos, Scopus, and Google Scholar, using predefined terms, selecting primary studies from case reports. 7 articles with a total of 10 patients were included; Of these, eight patients underwent this procedure in Brazil, one in the United States, and one in Chile. The distribution of the population was 3:7 between men and women with an average age of 35 years and a range between 23 to 49 years. In relation to the reported complications, 100 % of the patients presented facial asymmetry, 80 % presented facial edema, 30 % manifested sialocele, trismus 20 %, 40 % presented hematoma, 20 % compromised general state, 20 % presented dysphagia, in the cases of hypoesthesia, paresthesia, abscess, seroma, facial paralysis, odynophagia, fever were expressed in 10 % of the studied population. All the studies described a surgical reintervention after cosmetic removal of the bichat adipose body. The scarce literature and its low quality do not allow estimating the real percentage of possible complications, nor is it possible to determine their long-term results since there is no evidence of appropriate follow-up for these patients.

ABSTRACT

RESUMEN: El diente supernumerario de ubicación nasal es una patología de baja prevalencia en la población con diferentes formas y sintomatología clínica. Es importante establecer un diagnóstico respecto a sus características clínicas y radiológicas para realizar una planificación de tratamiento quirúrgica adecuada, con nula o escasas complicaciones post intervención. Presentación del caso: En el presente estudio se reporta el caso de un niño de 10 años de edad, sin antecedentes mórbidos, que recurre al servicio por presentar un diente supernumerario en la línea media hallado radiográficamente. El CBCT demuestra un mesiodens en el septum nasal, palatal inclinado e invertido, parcialmente erupcionado cubierto por mucosa nasal, con su corona en sentido a la cavidad nasal en relación a las fosas nasales. El diente fue extraído con anestesia general mediante un abordaje transoral a través de una vestibulotomía. El diente supernumerario nasal es una patología poco prevalente. Es importante conocer sus características clínicas y radiográficas ya que determinarán el tipo de abordaje a realizar. El grado de erupción, la distancia a la espina nasal anterior y su sintomatología asociada son fundamentales para determinar si el abordaje quirúrgico es intraoral o extraoral.


ABSTRACT: The supernumerary tooth of nasal location is a pathology of low prevalence in the population with different forms and clinical symptoms. It is important to establish a diagnosis regarding its clinical and radiological characteristics in order to carry out adequate surgical treatment planning, with few or no post-intervention complications. Case presentation: This study reports the case of a 10-year-old boy, with no morbid history, who presented a supernumerary tooth, found radiographically in the midline. CBCT showed a mesiodens in the nasal septum, tilted and inverted palatal, partially erupted covered by nasal mucosa, with its crown facing the nasal cavity in relation to the nostrils. The tooth was extracted under general anesthesia using a transoral approach through a vestibulotomy. The nasal supernumerary tooth is a rare pathology. It is important to know its clinical and radiographic characteristics since they will determine the type of approach to be used. The degree of eruption, the distance to the anterior nasal spine and its associated symptoms are essential to determine whether the surgical approach is intraoral or extraoral.

ABSTRACT

Los bisfosfonatos (BF) son fármacos ampliamente utilizados como estabilizadores óseos en el tratamiento de metástasis óseas, osteoporosis, enfermedad de Paget, entre otras patologías, debido a sus efectos anti-tumorales y a la característica de inhibir la actividad osteoclástica. La osteonecrosis maxilar asociada a BF, hoy en día osteonecrosis maxilar asociada a fármacos (ONMF) es definida como la presencia de hueso expuesto, no-vascularizado y necrótico en la cavidad oral por un periodo mayor a ocho semanas, con una historia positiva de tratamiento con fármacos anti-reabsorción ósea (BP, inhibidores del ligando RANKL) y/o anti-angiogénicos y sin antecedentes de tratamiento con radiación o metástasis obvia en los maxilares. La frecuencia de ONMF es incierta. La mandíbula es más frecuentemente afectada por ONMF que el maxilar. Pocos casos de ONMF en el maxilar han sido descritos con un diagnostico de sinusitis maxilar simultáneo. Tres casos con sinusitis maxilar asociada a ONMF son presentados en este trabajo. Todos los pacientes fueron mujeres con una historia positiva de cáncer de mama y tratamiento con bisfosfonatos. Los primeros dos casos, desarrollaron ONMF después de una extracción del tercer molar maxilar. El tercer caso con ONMF en el maxilar, sólo tenía antecedentes de curetaje periodontal. Una tomografía computada fue realizada y mostró compromiso del seno maxilar en todos los pacientes. Modalidades diagnósticas para evaluar la extensión de la necrosis y el compromiso del seno, como también alternativas de tratamiento son descritas en este estudio. Finalmente, una revisión actualizada de la literatura es presentada.


Bisphosphonates are widely used as bone-stabilizers in the treatment of osseous metastases, osteoporosis, Paget's disease and others,due to their ability to inhibit osteoclast activity and anti-tumor effects. Bisphosphonate-related osteonecrosis of the jaw, nowadays medication-related osteonecrosis of the jaw (MRONJ), is defined as the presence of exposed, non-vascularized and necrotic bone tissue in the oral cavity over a period of 8 weeks with a current or previous history of treatment with antiresorptive (bisphosphonates, RANKL ligand inhibitor) and/or antiangiogenic agents, and no history of radiation therapy to the jaws or obvious metastatic disease to the jaws. The frequency of MRONJ is unclear. The mandible appears to be more frequently affected by MRONJ than the maxilla. Isolated cases of maxillary MRONJ have been described in wich a simultaneous sinusitis maxillaris was diagnosed. Three cases of MRONJ associated with maxillaris sinusitis are presented. All cases were females with a positive history of breast cancer and bisphosphonate therapy. The first two, developed MRONJ after a third molar upper extraction. The third case with MRONJ, had a history of periodontal curettage. A computed tomography was performed and showed a maxillary sinus compromise in all patients. Imaging modalities to evaluate the extent of the necrosis and the sinus compromise, as also treatment options were described in this study. Finally, an updated literature review is presented.

ABSTRACT

The objective of this study was to evaluate the effect of Oreochromis niloticus cage culture promoted variations in the 13C and 15N in Corbicula fluminea (Mollusca; Bivalvia) and in the sediment of an aquatic food web. Samples were taken before and after net cage installation in the Rosana Reservoir (Paranapanema River, PR-SP). Samples of specimens of the bivalve filterer C. fluminea and samples of sediment were collected using a modified Petersen grab. All samples were dried in an oven (60 °C) for 72 hours, macerated to obtain homogenous fine powders and sent for carbon (delta13C) and nitrogen (delta15N) isotopic value analysis in a mass spectrometer. There were significant differences in the delta13C and delta15N values of the invertebrate C. fluminea between the beginning and the end of the experiment. There were no differences between the delta13C and delta15N values of sediment. These results indicate that the installation of fish cage culture promoted impacts in the isotopic composition of the aquatic food web organisms, which could exert influence over the native species and the ecosystem.


O objetivo deste estudo foi avaliar o efeito do cultivo de Oreochromis niloticus em tanques rede sobre os valores de 13C e 15N em tecidos Corbicula fluminea (Mollusca; Bivalvia) e no sedimento da cadeia alimentar aquática. As amostragens foram realizadas em períodos prévios e posteriores a instalação de tanques redes no reservatório de Rosana (Rio Paranapanema, PR-SP). As amostras de espécimes de bivalves filtradores exóticos e as de sedimento foram coletadas utilizando uma versão modificada do pegador tipo Petersen. Todas as amostras foram secas em estufa (60 °C) durante 72 horas, maceradas até obtenção de pó fino e homogêneo e enviadas para determinação do carbono (delta13C) e do nitrogênio (delta15N) em espectrofotômetro de massa. Houve diferenças significativas nos valores delta13C e delta15N do invertebrado C. fluminea entre o início e o fim do experimento. Entretanto, não foram evidenciadas diferenças nos valores delta13C e delta15N presente no sedimento. Estes resultados demonstram que a instalação dos tanques rede promoveram impactos na composição isotópica do invertebrado, que podem influenciar as espécies nativas e o ecossistema.

ABSTRACT

El score de Gleason (SG) es el sistema más utilizado en la etapificación del cáncer prostático (CP). La correlación entre el SG de la biopsia prostática por punción (BP) y el obtenido en la prostatectomía radical (PR) no es exacta. El objetivo de este estudio fue comparar el SG de la BP con el obtenido en la pieza quirúrgica de la PR en nuestro hospital. Creemos que existe un nivel moderado de concordancia entre ambas muestras. Se incluyeron los pacientes sometidos a PR entre 1993 y 2010 en el Hospital Militar de Santiago (HOSMIL). Se estableció como SG sobreestimado cuando el SG de la biopsia por punción era mayor al de la PR, y SG subestimado cuando el SG obtenido en la biopsia era menor al obtenido en la PR. Se utilizó la medida estadística Kappa (K) para determinar su nivel de concordancia. El estudio incluyó 534 pacientes. Se encontró una concordancia de 62 por ciento. La sobreestimación fue de 6,7 por ciento y la subestimación fue 31,2 por ciento. El valor del índice de concordancia Kappa (K) fue de 0,3186. Se encontró un índice de concordancia débil. Esto se podría explicar por la escasa muestra disponible en la biopsia, comparada con la pieza completa de la PR, entre otros factores. Se asemeja a resultados internacionales, que afirman que la subestimación es la situación más frecuente...


Gleason Score (SG) is the most frequently used system for prostate cancer (CP) staging. The correspondence between the SG of the prostate biopsy and the radical prostatectomy is not exact. The purpose of this study was to compare the SG of the biopsy with that obtained at radical surgery in our hospital. We relieve that there is a moderate level of correspondence between both specimens. We included all patients who underwent Radical Prostatectomy between 1993 and 2010 in the Hospital Militar de Santiago (HOSMIL). We defined overestimation when the SG in the biopsy was higher than in the Radical Prostatectomy; and underestimated when lower. The statistical measurement Kappa (K) was used for the analysis. 534 patients where studied. The correspondence was 62 percent. Overestimation was 6,7 percent and underestimation was 31.2 percent. Kappa (K) was 0.3186 and this is considered weak. This could be explained in part due to the small size of the tissue sample, when compared to the complete prostate after surgery. Our experience is similar to International reports, where underestimation is also frequent...

ABSTRACT

Objetivo: conocer la frecuencia de intimidación en colegios nacionales de las tres regiones del Perú donde ha existido violencia política y determinar los factores de riesgo asociados.Métodos: estudio transversal, analítico, acerca de la intimidación en cinco departamentos del país: Ayacucho (Huamanga), Cusco (Sicuani), Junín (Satipo), Huancavelica y Lima (Ñaña). Después de determinar el tamaño de muestra de los estudiantes y efectuar la selección aleatoria de los salones de clase se empleó un cuestionario previamente validado para efectuar una encuesta en 1633 estudiantes. Estadísticamente se buscaron porcentajes, asociación de variables con intimidación, regresión logistica y se construyó una curva R.O.C.Resultados: la incidencia de intimidación tuvo un promedio de 50.7 por ciento. Las variables asociadas significativamente con intimidación en la regresión logistica fueron apodos, golpes, falta de comunicación, llamar homosexual, defectos físicos, necesidad de trabajar, necesidad de atención médica, acoso, escupir, obligar a hacer cosas que no se quiere, discriminación e insulto por correo electrónico.Conclusiones: la intimidación tiene origen multicausal, ocasiona problemas en la salud, fobia escolar, y el pronóstico a largo plazo para víctimas y agresores es negativo, pudiendo verse envueltos en problemas con la ley.


Objective: To know the frequency of bullying in national schools in the three peruvian regions where has existed political violence, and determine the associated risk factors. Methods: cross section study, analytic, about bullying in national schools of five departments Ayacucho (Huamanga), Cusco (Sicuani), Junín (Satipo), Huancavelica and Lima (Ñaña). After determine the sample size of students in each school and the aleatory election of the classrooms a questionnaire validated previously was used, and we did a survey in 1633 students. Statistically We look for percentage,s, associations, logistic regression measures and build a R.O.C curve. Results: The incidente of bullying was in average 50,7 percent The variables significant associated with bullying in the logistic regression were nicknames, beats, no communication, homosexual insult, physical defect, work need, medical attendance, pursue, spitted, forced to do thing than they didn't want, discrimination and e-mail inssult. Conclussions: The bullying has multicausal origin, give health problems, scholar phobia, and at long time the prognosis for victims and agressors is negative and they could be involved in problems with the law.

ABSTRACT

BACKGROUND: The incidence of cutaneous malignant melanoma continues an increasing trend worldwide and has had the highest rise in incidence of all malignancies during the last decades. Mortality rates for melanoma have remained relatively stable in most countries despite the increase in incidence rates. The purpose of this study is to describe the epidemiological trends of malignant melanoma in Puerto Rico from 1987 to 2002 and to compare these findings with those previously reported for Puerto Rico as well as with those reported for other countries. METHODS: All cases of malignant melanoma reported to the Puerto Rico Cancer Registry from 1987 to 2002 were included. Age-adjusted incidence and mortality rates were calculated. Trends were compared by age, gender, anatomical location of the tumor and tumor thickness. RESULTS: There were 1,568 new melanoma cases reported between 1987 and 2002 in Puerto Rico, comprising a 50% overall increase in incidence during this period. Male to female incidence ratio was 1:0.86. The most common anatomical location in women was the lower extremity followed by the head and neck region. In men, the most common anatomical location was the trunk, followed by the head and neck region. Most of the superficial tumors (< 1mm) were located on the trunk followed by the lower limb. The most common specific histologic diagnosis reported was melanoma in situ. In 40.8% of the cases the tumor thickness value was not provided. The number of thinner melanomas (< 1mm) reported increased during the study period. Mortality rates were slightly higher for men than for women, still mortality rates remained stable for both genders and all age groups analyzed. CONCLUSIONS: Melanoma incidence rates continue to increase in Puerto Rico. This, in combination with an increase in the diagnosis of thin melanomas, suggests that the stable mortality rates may be due, in part, to earlier diagnosis and improved overall prognosis.

ABSTRACT

Streptococcus bovis forma parte de la flora intestinal humana. Las infecciones clínicas mes importantes causadas por este microorganismo son bacteriemia y endocarditis, estando la primera asociada con patologías intestinales, especialmente con enfermedades malignas como cancer o poliposis de colon. Las infecciones de diversos sitios anatómicos, aunque infrecuentes, pueden en ciertas instancias ser la sola clave de la presencia de malignidad. Estas infecciones se relacionan con la invasión de tejidos u órganos próximos al tumor o pueden ser secundarias a una siembra a distancia, a través de la bacteriemia originada en tejido tumoral necrótico. En este reporte se describe el caso de una paciente con un quiste de ovario abscedado en el que se aisló Streptococcus bovis I y Enterobacter cloacae. Durante el tratamiento se diagnosticó cancer de colon

ABSTRACT

La nocardiosis es una enfermedad producida por un actinomiceto aerobio de la familia Nocardiaceae. Habita en suelos y, usualmente, penetra a través del tracto respiratorio de pacientes inmunocomprometidos. Los varones son afectados con frecuencia que las mujeres. Presentamos los dos primeros casos de pacientes de sexo femenino con infección HIV/SIDA/nocardiosis, diagnosticados en nuestro hospital. Ambas pacientes tenían un severo compromiso inmunológico, con cargas virales superiores a las 10.000 copias/ml, y en las dos, la forma de presentación fue pulmonar. El diagnóstico de nocardiosis se realizó en las dos enfermas a partir del examen directo y cultivos de esputo. Una de las pacientes recibió cotrimoxazol+amikacina y la otra fue tratada con cefalosporinas. Ambas tuvieron una evolución satisfactoria de sus lesiones pulmonares. Se concluye afirmando que debe incluirse a la nocardiosis en el diagnóstico diferencial de las neumonías extrahospitalarias en pacientes HIV positivos, en especial en aquellas neumopatías de curso subagudo o crónico

ABSTRACT

PURPOSE: Identify several HIV risk behaviors among adolescent students. METHODS: The sample (n = 3,648) was selected using a two-staged stratified cluster sampling design, and weighted to represent all junior high and high school students. RESULTS: About 28.8 of the students reported ever having sexual activity. Less than half of the sexually active (44.5) used condoms during their last sexual activity; 27.6 used them always. Only 54.7 knew correctly > 75 of the HIV knowledge questions. A HIV risk scale was constructed using five risk factors. About 15.9 of the students did not have any risk factor, 36.2 had one, 47.9 had two or more. Males and high school students had significantly more risk factors. Half of the students will abstain from having sex next year because they don't want to get HIV/AIDS. CONCLUSIONS: It is important to implement effective HIV prevention programs for adolescents in order to change their attitudes and behaviors

ABSTRACT

PURPOSE: To describe the services delivered by the Family Medicine Physicians at a Community Health Center. METHODS: All information from patient visits during the natural year 1996 were registered using a commercialized computer program. The information was gathered by different means: initial interview, physician's report, records, and personal interviews. RESULTS: A total of 13,203 visits were registered; this represent a total of 4,493 patients. Most of the patients were women, and with a mean age of 38. As expected, most of the patients have Medicaid. The most common conditions seen were hypertension, diabetes, and respiratory diseases. The mean number of visits during the year for almost all conditions was three. Most of the children and adolescents visit the Center due to respiratory conditions, while adults come due to hypertension, diabetes, and musculoskeletal conditions

ABSTRACT

Se realizaron estudios sobre levaduras del género Kluyveromyces (K. fragilis 507, K. lactis 29 y K. lactis 10), que crecen en lactosa como única fuente de carbono, ya que poseen el sistema enzimático para la utilización de este azucar. Se determinó la actividad de ß-galactosidasa en medios con glucosa y con lactosa, en cultivos de estas tres cepas en fase log. Al agregar entre ) y 12% v/v de etanol a células tratadas con tolueno, no se observó inhibición enzimática para la cepa K. lactis 10 que tenía la mayor actividad enzimática (704,4 Unidades). Como existe la posibilidad de utilizar industrialmente suero concentrado 4 veces como sustrato que contenga lactosa, se realizaron ensayos de fermentación a 30 C las tres cepas, en medios que contenían inicialmente 16,5 y 24,5% de lactosa. Al cabo de 48 h la lactosa residual fue prácticamente cero, lográndose concentraciones de etanol directo entre 7,60 y 10,10% v/v. Es de esperar que la velocidad de fermentación de un disacárido como lactosa, esté relacionada con la velocidad de hidrólisis del mismo azúcar, por lo que cepas con una mayor velocidad enzimática hidrolítica debieran poseer mayor velocidad de fermentación. En este caso no se observó tal comportamiento, por cuanto cepas con actividad enzimática tan distinta como K. lactis 10 (704,4 U) y K lactis 29(189,7 U) no presentaron mayores diferencias en la producción de etanol a partir de lactosa

ABSTRACT

Brewing yeast strains of the genus Saccharomyces uvarum (carlsbergensis) were grown on media containing p-fluorophenylalanine (p-FPA). After the treatment, non-sporulation colonies were selected, and these were mated with haploid strains of flocculent and amylolytic yeasts of the genus Saccharomyces. The selected hybrids, which carried the greater part of the parental genetic markers and produced asci containing 2,3 and 4 spores per ascus, were placed on sporulation medium. Some aspects of the probable action of p-FPA are discussed.

ABSTRACT

A 56 year-old man with diabetes mellitus and pain, muscle weakness and wasting in both thighs, of three months duration, had a diagnosis of diabetic amyothrophy. The ultrastructural study of a biopsy from quadriceps femoris muscle showed usual findings in muscle fibers and two not previously reported alterations: capillary necrosis and mononuclear cell infiltration consisting of macrophages, lymphocytes and plasma cells. The etiopathogenesis of muscle damage in diabetic amyotrophy is discussed
