MORALES-AVALOSSUMMARY: Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each specimen was analyzed to determine the prevalence of each of the different morphologies of the AIIS based on the classification proposed as Type 1: the presence of a concave surface between the AIIS and the acetabular rim; Type 2A: the presence of a flat surface between the AIIS and the acetabular rim; Type 2B the presence of a convex surface between the AIIS and the acetabular rim; and Type 3: the AIIS protrudes inferiorly toward the anterior acetabulum. A prevalence of 69.87% was determined for Type 1 AIIS (320/458). In regard to abnormal morphology, prevalences of 17.90% (82/458), 3.71% (17/458) and 8.52% (39/458) were determined for type 2A, Type 2B and Type 3, respectively. The prevalence of abnormal AIIS morphology was 30.30% (80/264) in male specimens and 29.90% (58/194) in female specimens. This study demonstrates the prevalence of the different morphologies of the AIIS, providing information that will be useful in determining the role of the AIIS in the emergence of subspine hip impingement.
Introducción: la pobre ganancia de peso del prematuro es una causa de estancia hospitalaria prolongada. Los triglicéridos de cadena media (MCT-oil) enteral son una estrategia para obtener ganancia de depósitos de grasa corporal y masa muscular. Objetivo: investigar el papel del MCT-oil como suplemento, al valorar la circunferencia braquial y el índice de circunferencia braquial/perímetro cefálico (CB/ PC). Material y métodos: estudio observacional, comparativo, de casos y controles. En el primer grupo, prematuros con suplementación con MCT-oil. En el grupo control, prematuros sin suplementación con MCT-oil. Dosis de 2 mL/kg/ día en ocho tomas, administrado directamente en la boca y coincidiendo con las tomas de leche. Resultados: al alta, el grupo con MCT presentó media de perímetro braquial mayor al grupo control (7.2 ± 0.77 vs 6.4 ± 0.46) p < 0.05. A las cuatro semanas de seguimiento ambulatorio, el grupo con

La administración de MCT-oil enteral es una estrategia para ganancia de depósitos de grasa corporal y masa muscular. Material y métodos: estudio observacional, comparativo, de casos y controles. El primer grupo: prematuros con suplementación con MCT-oil. El grupo control, prematuros sin suplementacion con MCT-oil. Dosis de 2 ml/kg/día en 8 tomas administrado directo en la boca coincidiendo con las tomas de leche. Resultados: al egreso, el grupo con MCT presentó media de perímetro braquial mayor al grupo control (7.2±0.77 vs 6.4±0.46) p<0.05. A las 4 semanas de seguimiento ambulatorio, el grupo con MCT tuvo mayor circunferencia braquial que el grupo control (10.4 ±1.4 vs 8.6 ±1.7) p<0.05. Comparando el índice CB/PC al egreso, el grupo con MCT tuvo mayor índice CB/PC que el grupo control (0.2314 ±0.26 vs 0.2108 ±0.14) p <0.001, pero a las 4 semanas no hubo diferencia significativa (p=0.080). Discusión: el uso de MCT-oil como suplemento para el prematuro es buena estrategia para ganancia de depósitos de grasa corporal y masa muscular.
