Osteoma de oído medio asintomático

Resumen El osteoma de oído medio es un tumor poco común, de crecimiento lento y características benignas. Frecuentemente cursa de forma asintomática y su diagnóstico suele ser casual como en el caso que exponemos. Se presenta el caso de un varón de 26 años, que consultó por odinofagia y otalgia derecha en el contexto de una infección de vía aérea alta. Al explorarlo mediante otoscopia se visualizó en el oído izquierdo una lesión blanquecina y redondeada retrotimpánica compatible con osteoma de oído medio. El tratamiento de elección en pacientes con osteomas de oído medio sintomáticos es la cirugía. Sin embargo, en pacientes asintomáticos el seguimiento es la opción más recomendada.

Abstract The middle ear osteoma is a benign, infrequent, slow-growing tumor. This lesion is frequently asymptomatic and its diagnosis is usually accidental, as the case presented here. We present a case of a 26-year-old man who consulted for odynophagia and right ear pain in the context of an upper airway infection. By otoscopy in the left ear, we observed a whitish retrotympanic lesion that was compatible with a middle ear osteoma. To manage symptomatic patients with middle ear osteomas, surgery is the treatment of first choice. Nevertheless, for asymptomatic patients, follow up is recommended.

Trombosis de la vena ovárica: serie de 3 casos en el Hospital Universitario de Cabueñes / Thrombosis of the ovarian vein: series of 3 cases at the Hospital Universitario de Cabueñes

Se presentan 3 casos de trombosis de la vena ovárica, uno en relación a cirugía pélvica y dos durante el postparto. La trombosis de la vena ovárica es una complicación rara, de presentación clínica inespecífica, lo que hace plantearse un diagnóstico diferencial con otras patologías más frecuentes (apendicitis, pielonefritis, etc), siendo la TAC el gold standard para su diagnóstico. El tratamiento más adecuado son los anticoagulantes.

We report 3 cases of varian vein thrombosis, one in relation with pelvic surgery and 2 during the postpartum period. The ovarian vein thrombosis is a rare complication, with inespecific symptoms, that is why it is obligatory to propose a differential diagnosis with more frecuent patologies (appendicitis, pyelonephritis, etc.), the CAT is the gold standard in its diagnosis. Anticoagulants are the most suitable treatment.

Seudoquiste pretibial tras la reconstrucción del ligamento cruzado anterior con tornillo biocomposite / Pretibial pseudocyst after anterior cruciate ligament reconstruction with a biocomposite screw

Resumen: Presentamos el caso de un paciente con un nódulo subcutáneo pretibial de unos 20 × 15 mm dos años después de la reconstrucción del ligamento cruzado anterior con un injerto autólogo hueso-tendón-hueso de tendón rotuliano fijado en la tibia con un tornillo de interferencia reabsorbible de ácido poli-D, L-láctico y fosfato β-tricálcico. Se resecó una lesión seudoquística subcutánea con contenido líquido blanquecino y abundante fibrosis circundante, que penetraba en el túnel tibial sin comunicar con la articulación. El análisis anatomopatológico describió tejido fibroso con células multinucleadas y partículas refringentes, que sugería una reacción a cuerpo extraño. Después de la intervención, la sintomatología remitió y el individuo pudo recuperar su actividad deportiva previa en menos de dos meses. No se ha encontrado en la literatura médica publicada hasta la fecha ningún trabajo que describa esta complicación en un sujeto con un tornillo de interferencia tibial de ácido poli-D, L-láctico y fosfato β-tricálcico.

Abstract: We report the case of a patient who presented a pretibial extra-articular cyst two years after an arthroscopically assisted ACL reconstruction using an autologous bone-patellar tendon-bone graft. The tibial fixation was achieved with a bioabsorbable screw made of poly-L, D-lactic and β-tricalcium phosphate (β-TCP). A subcutaneous pseudocystic lesion was excised. It consisted of a capsular fibrous tissue with minimal milky fluid (1 ml) centrally. It penetrated into the tibial tunnel but did not communicate with the knee joint space. The histopathological analysis demonstrated fibrous tissue with multinucleated giant cells and refractile particles which suggested a foreign body reaction. After the surgery, the patient recovered perfectly well and he returned to his pre-injury level of physical activity in two months. To the best of our knowledge, this is the first report of this complication in a patient with a biocomposite screw made of poly-L, D-lactic and β-tricalcium phosphate (β-TCP).

Ocorrência de desvios posturais em escolares do ensino público fundamental de Jaguariúna, São Paulo / Occurrence of postural deviations in children of a school of Jaguariúna, São Paulo, Brazil

Objetivo: Avaliar a postura de escolares do ensino público fundamental e diferenciar as alterações que fazem parte do crescimento normal das compensatórias.Métodos: Trata-se de um estudo analítico, descritivo, de corte transversal, no qual se realizou avaliação postural em escolares de primeira a quarta série de uma escola pública da cidade de Jaguariúna, situada no interior do Estado de São Paulo. Cada aluno foi avaliado nos planos coronal-anterior, coronal-posterior e sagital, utilizando-se o método de Kendallcomo referência de alinhamento postural normal.Resultados: A avaliação postural de 247 escolares (131 masculinos e 116 femininos) identificou a seguinte incidência de alterações: desnível (50,2%) e protrusão de ombro (39,7%), escápula alada (40,5%), aumento do ângulo valgo de joelho (29,6%), inclinação (21,5%) e anteroversão pélvica (19%), hiperextensão de joelho (19%), rotação de fêmur (12,9%), protrusão (11,7%) e inclinação cervical (15,4%), cifose torácica (9,7%) e hiperlordose lombar (26,3%).Conclusões: Houve elevada incidência de escápula alada, desnível e protrusão de ombro, aumento do ângulo valgo de joelho e hiperlordose lombar, consideradas normais durante o desenvolvimento da criança. As inclinações e a protrusão cervical, alterações que necessitam de intervenção precoce, também foram identificadas.

Objective: Evaluate the posture of students from a public school in Brazil and to identify the differences between normal deviation during growth and compensatory alterations. Methods: Students from first to fourth grade of a public school in the city of Jaguariúna, São Paulo, Brazil, were evaluated. The students were positioned at sagital anterior and posterior coronal planes for postural assessment. Kendall points were used as the normal reference. Results: 247 students were evaluated, 131 boys and 116 girls, and the main postural deviations found were: shoulder unbalance (50.2%), protracted shoulder (39.7%), abducted scapula (40.5%), knock-knee (29.6%), pelvic unbalance (21.5%), pelvic anteversion (19%), knee hyperextension (19%), medial rotation of hip (12.9%), protracted cervical (11.7%), head tilt (15.4%), thoracic hyperkyphosis (9.7%) and lumbar hyperlordosis (26.3%).Conclusions: A high incidence of postural alterations was detected in school children. Some of the postural alterations, such as abducted scapula, unbalance and protraction of the shoulders, knock-knee and lumbar hiperlordosis, normally occur and they are naturally corrected during growth. However, some postural problems, such as protraction and inclination of the cervical spine, were also prevalent and they require early intervention.

La búsqueda de creencias alimentarias a inicios del siglo XXI / In search of nutritional beliefs at the beginning of the century

En este estudio se identificaron creencias alimentarias, en usuarios de dos centros de salud de la Comuna Pedro Aguirre Cerda de la Región Metropolitana.Se demostró que algunas creencias han logrado ser transmitidas por la red primaria y secundaria, de tal manera que aún tienen vigencia en la población. En tanto, han surgido otras creencias relacionadas con los problemas actuales de salud (enfermedades crónicas no transmisibles), que contrastan con algunas existentes hace más de 50 años, relacionadas con problemas de salud prevalentes en esa época (enfermedades parasitarias). No es posible hacer generalizaciones dado las características de la muestra.

In this study we identified nutritional beliefs associated with health, the participants were two Health Departmnet of Pedro Aguirre Cedra located in the Metropolitan Area. It shows that some of them had been transmitted by the primary and secondary red, which at any rate still valid in the population, meanwhile others beliefs has been created related with actual problems of health (chronic sickness non transmissible), they contract with some in existence 50 years ago that related to health issues, more prevalent in that period( parasitic sickness).It is not possible to generalize, giving the characteristic of the sample.
