ABSTRACT

La ingesta accidental de más de un imán puede producir complicaciones graves. Los protocolos actuales recomiendan la extracción endoscópica de ser posible. El objetivo de este trabajo es presentar un caso clínico de una ingesta de dos imanes y la técnica endoscópica de extracción. Niño de 11 años que acudió a Urgencias tras la ingesta de dos imanes, asintomático. En la radiografía de abdomen, se identificaron dos cuerpos extraños radiopacos, aparentemente unidos, en la cámara gástrica. Se realizó una endoscopía bajo anestesia general en quirófano. Para facilitar la extracción, se colocó, encima de la pared abdominal, a nivel gástrico, un imán de neodimio. En la endoscopía, se observaron dos pequeños imanes localizados y fijados en la cara anterior del estómago. Una vez localizados, se retiró el imán externo y se procedió a su extracción con cesta


The ingestion of more than one magnet can cause multiple complications. Current protocols recommend endoscopic extraction if possible. We report a patient who swallowed two magnets and the endoscopic extraction technique. An 11-yearold boy presented at the Emergency Room after ingesting two small magnets, being asymptomatic. In the abdominal x-ray two radiopaque bodies were identified at the gastric chamber, apparently together. A gastroscopy was done in the operating room under general anaesthesia. To enable the extraction, a neodymium magnet was placed externally at the abdominal wall. In the endoscopic image, the two magnets were fixed to the anterior gastric wall. Once located, the neodymium magnet was removed and the two magnets were retrieved with an endoscopic basket.

ABSTRACT

ABSTRACT Nocardia is an opportunistic pathogen that causes respiratory infections in immunocompromised patients. The aim of this study was to analyze the epidemiology, clinical significance and antimicrobial susceptibility of Nocardia species isolated from eight children with cystic fibrosis. The isolated species were identified as Nocardia farcinica, Nocardia transvalensis, Nocardia pneumoniae, Nocardia veterana and Nocardia wallacei. N. farcinica was isolated in three patients and all of them presented lung affectation with a chronic colonization and pneumonia. N. farcinica showed resistance against gentamicin, tobramycin, cefotaxime, but was susceptible to trimethoprim-sulfamethoxazole and amikacin. N. transvalensis, which was isolated from two patients, showed an association with chronic colonization. N. transvalensis was resistant to tobramycin and amikacin, but susceptible to ciprofloxacin, trimethoprim-sulfamethoxazole and cefotaxime. N. veterana, N. pneumoniae and N. wallacei were isolated from three different patients and appeared in transitory lung colonization. N. veterana and N. pneumoniae were susceptible to imipenem, trimethoprim-sulfamethoxazole, amikacin, tobramycin, and cefotaxime. N. wallacei was resistant to amikacin, tobramycin, imipenem, and trimethoprim-sulfamethoxazole and susceptible to ciprofloxacin and cefotaxime. All the isolates were identified up to species level by 16S rRNA gene sequencing. The presence of Nocardia in the sputum of patients with cystic fibrosis is not always an indication of an active infection; therefore, the need for a treatment should be evaluated on an individual basis. The detection of multidrug-resistant species needs molecular identification and susceptibility testing, and should be performed for all Nocardia infections.

ABSTRACT

Introducción y objetivos: La enfermedad cardiovascular constituye la primera causa de muerte y de gastos sanitarios debido a sus consecuencias. En prevención secundaria, los programas de rehabilitación cardiaca mejoran el estado funcional y la calidad de vida, e incrementan la supervivencia. Métodos y materiales: Estudio observacional, descriptivo y prospectivo, en el que se incluyeron 31 pacientes (19 hombres y 14 mujeres), con edad promedio de 64 ± 11 años. El test de caminata de 6 minutos sirvió para estimar el consumo de oxígeno máximo indirecto (VO2máx). Se midió la frecuencia cardiaca y se estimó el doble producto como indicadores hemodinámicos. Las pruebas se realizaron antes y después de 12 sesiones de entrenamiento entre el 50 y 70% de la frecuencia cardiaca máxima, 60 min, 3 veces por semana, durante un mes. Resultados: Luego de la intervención, se observaron mayores valores en el VO2 (9,6 ± 2 mL/kg-1/min-1 vs. 11,09 ± 1,9 mL/kg-1/min-1; p = 0,002) y en la distancia alcanzada en el test (244,5 ± 80,1 m vs. 303,2 ± 78,1 m; p = 0,002). No hubo diferencias en los indicadores hemodinámicos (p > 0,05). Conclusiones: El programa de rehabilitación cardiaca reportó una mejoría de tolerancia al ejercicio para los pacientes posquirúrgicos cardiovasculares en promedio del 14%, sin modificar la función hemodinámica.


Introduction and objectives:Cardiovascular disease is the leading cause of death and medical expenses due to its consequences. In secondary prevention, cardiac rehabilitation programs improve functional status, quality of life and overall survival. Methods and materials: An observational, descriptive and prospective study was performed. Thirty one subjects (19 male, 14 female), mean age 64 ± 11 years. The 6-minute walk test served to estimate the indirect maximal oxygen consumption (VO2max). We measured the heart rate and double product was estimated as hemodynamic indicators. The tests were performed before and after 12 training sessions at between 50 and 70% of maximum heart rate, for 60 min, 3 times a week, during one month. Results: After the intervention we observed higher values of VO2 (9.6 ± 2.0 mL.kg-1.min-1 vs. 11.09 ± 1.9 mL.kg-1.min-1; p = 0.002) and a longer distance achieved in the walking test (244.5 ± 80.1 m vs. 303.2 ± 78.1 m; P = .002). There were no differences in hemodynamic indicators (P > .05). Conclusions: Cardiac rehabilitation program reported an improvement in exercise tolerance in post-surgical cardiovascular patients in a 14% of the cases. It did not show a variation in hemodynamic function.

ABSTRACT

La pérdida de dientes superiores causa reabsorción del proceso alveolar y la neumatización del seno maxilar. La implantología oral ha permitido solucionar la perdida de dientes, sin embargo, cuando existe neumatización del seno maxilar, la disponibilidad ósea se ve disminuida, dificultando el procedimiento implantologico. Para remediar esta situación se efectúa la técnica quirúrgica de levantamiento del piso del seno maxilar, la que puede tener complicaciones por la morfología interna del seno, específicamente por la presencia de septos intrasinusales. El objetivo de este estudio es verificar la presencia y distribución de los septos intrasinusales, debido a su importancia en técnicas quirúrgicas realizadas en implantología oral. Se realizó un estudio descriptivo, basado en el análisis visual de huesos maxilares aislados. De 65 huesos se seleccionaron 51 (42 dentados y 9 edéntulos) que cumplían con determinados criterios de inclusión. La segunda parte del estudio consistió en dividir topográficamente el piso del seno en tres regiones: anterior a la cresta cigomato alveolar, en relación a ella, y posterior a la cresta. La observación de los septos fue realizado por un único examinador, asistido por un dispositivo USB, con 4 leds de alta luminiscencia. De los 51 maxilares analizados se obtuvo: 74,5 por ciento, presentaron al menos un septo intrasinusal, 25,4 por ciento, no presentaron septos visibles. Los maxilares que presentaron un único tabique correspondieron al 33,3 por ciento de la muestra, el 19,6 por ciento de la muestra presento sólo dos tabiques, el 15,7 por ciento presentó tres tabiques, mientras que los maxilares que presentaron más de tres tabiques intrasinusales correspondieron sólo al 5,9 por ciento. Del total de tabiques encontrados (75 tabiques) el 42 por ciento se observó en la región anterior, 21 por ciento en la región de la cresta cigomato alveolar y el 37 por ciento en la región posterior del seno maxilar. De los 42 maxilares en condición...


The loss of upper teeth causes alveolar process resorption and maxilary sinus pneumatization. Oral implantology has solved these losses, however, when pneumatization of the maxillary sinus exists, bone availability is diminished, difficulting implantology procedure. To remedy this situation, the surgical technique of lifting the maxillary sinus floor is indicated, which can have complications because of the internal maxillary sinus morphology, specifically the presence of intrasinusal septa. The aim of this study is to verify the presence and distribution of intrasinusal septa, due to its importance in surgical techniques performed in oral implantology. We conducted a descriptive study, based on visual analysis of isolated maxilary bones. Of 65 bones, 51 (42 dentate and 9 edentulous)were selected that met certain inclusion criteria. The second part of the study was, to divide the sinus floor topographically into three regions: anterior to the zygomatic alveolar crest, in relation to it, and posterior to the crest. The observation of the septa was performed by a single examiner, assisted by a USB device with 4 high-luminance LEDs. Of the 51 maxillary analyzed obtained: 74.5 percent had at least one intrasinusal septum, 25.4 percent showed no visible septa. The maxilary bones that had a single septum corresponded to 33.3 percent of the sample, 19.6 percent of the sample had only two septa, 15.7 percent had three septa, while the maxillary bones that had more than three intrasinusal septa corresponded only to 5.9 percent. Of all septa found (75 septa) 42 percent was observed in the anterior region, 21 percent in the region of the zygomatic crest and 37 percent in the posterior region of the maxillary sinus. Of the 42 dentate maxillary bones in 88,1 percent present intrasinusal septa, while the total edentulous maxillary bones (9) only 11 percent present intrasinusal septa. This study establishes that a significant portion of the maxillary bones have...
