RESUMO
Background Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic hepatic disorder in the pediatric population and has grown along with the obesity pandemic in which we live today. Adipose tissue storage in the upper body segment has been positively correlated with visceral adiposity and metabolic disease, which suggests that neck circumference could represent an easily accessible and replicable anthropometric measurement to identify patients with a higher risk of developing NAFLD. The main purpose of this study is to determine if there is an association between neck circumference and NAFLD. The secondary objectives are to establish cutoff values based on gender and puberty staging. Methods We included a sample pediatric population of 112 patients diagnosed with obesity aged between 6 and 18 years. We performed anthropometric and metabolic measurements on every patient, and NAFLD diagnosis was determined with hepatic ultrasound. Results The neck circumference was larger in NAFLD pediatric patients compared to those without NAFLD (p = 0.001). In a multivariate analysis, the neck circumference was associated with NAFLD as an independent risk factor (odds ratio [OR] = 1.172; 95% CI = 1.008-1.362; p = 0.038). Tanner 2-3 = 35 cm and Tanner 4-5 = 38 cm were established as risk cutoff values to develop NAFLD in the male adolescent population. Conclusions There is an association between the neck circumference and NAFLD in pediatric patients with obesity, particularly in the male population.

Se realizaron exámenes por ultrasonido (US) convencional y de alta resolución del cuello en 50 pacientes con masa palpable cervical (MPC), 35 mujeres y 15 hombres entre 14 y 78 años, todos fueron confirmados por estudio histopatológico. La sensibilidad del US para detectar correctamente el sitio anatómico de las MPC fue del 82 por ciento (41 de 50). El US fue más sensible en identificar lesiones de origen tiroideo 96.1 por ciento (25 de 26) respecto a las no tiroideas 62.5 por ciento (15 de 24). Los nódulos tiroideos únicos fueron benignos en 78.4 por ciento y malignos en 21.6 por ciento. Todas las tiroides multinodulares fueron benignas. Respecto a las masas no tiroideas se observó una gran variedad de patologías

Los autores presentan la experiencia obtenida con el uso de ultrasonido transrectal en un grupo de 264 pacientes examinados en 1990 en el Servicio de Radiología del Hospital General de México, entre los cuales 31, tuvieron diagnóstico ultrasonográfico de cáncer de próstata. En 24/31 (80.64%), se logró obtener una confirmación histológica. Se encontró la presencia de cáncer en 17/24 (70.83%) e hiperplasia fibroglandular en 8/24 (29.16%). La sensibilidad fue de 66.6%y la especificidad de 68%. Se comentan los resultados y se revisa la literatura.
