Anthropometric study of the scapula in a contemporary population from granada. Sex estimation and glenohumeral osteoarthritis prevalence.

Anthropometric studies of the scapula have been rare in Spanish populations, nevertheless they are of current interest in forensic anthropology for estimation of sex. Although the estimation of sex is usually carried out on the pelvis and skull, other measurements related to the scapula can be helpful when the skeletal remains are incomplete. Glenohumeral osteoarthritis development is influenced, among others, by the morphology of the scapula, which is one of the less studied aspects. We carried out a descriptive study of anthropometric parameters in a series of 157 scapulae (82 individuals) on bone remains dated to the 20th century from a population of Granada (Southern Spain). Seventy seven (49%) were right-side and 80 (51%) left-side; 72 (45.9%) were from males and 85 (54.1%) from females, and the mean age at death was 70.76±11.7 years. The objective was to develop a discrimination function for sex estimation based on anthropometric parameters of the scapula other than those considered to date, and to analyze the prevalence of glenohumeral osteoarthritis in relation to selected anthropometric parameters. A logistic regression model based on parameters of the upper-external segment of the scapula was done. The obtained formula: 1/1+e^ (- (-57.911 + 0.350*B + 0283*C + 0.249*b + 0.166*a +-0.100*ß) classifies male sex with 98.3% accuracy and female sex with 92.1%. Glenohumeral osteoarthritis was detected in 16.6% of individuals and was related to age (p<0.05), scapular length (p<0.05), glenoid width (p<0.05), glenopolar angle (p<0.05), and α angle (p<0.05) in bivariate analyses but showed no significant associations in multivariate analyses. This approach can be useful for anthropological-forensic identification when scapula remains are incomplete. Glenohumeral osteoarthritis is significantly associated with a smaller α angle.

Metástasis hepáticas de origen colorrectal sincrónicas: ¿intervención simultánea o secuencial? / Simultaneous or sequential treatment of liver metastases of colon cancer?: experience in 76 patients

Background: Synchronous liver metastases of colon cancer can be managed with sequential or simultaneous surgical management of the primary tumor and the metastases. Aim: To compare the evolution of patients whose liver metastases were treated sequentially or simultaneously. Material and Methods: Retrospective analysis of 76 patients aged 63 +/- 11 years (67 percent males). In 25, metastases were managed simultaneously and in 51 there were treated sequentially after a period of chemotherapy. All interventions were performed by the same surgeon. Results: Patients treated sequentially had a higher number of metastases andmore lymph nodes involved than their counterparts treated simultaneously. The overall resectability index was 78 percent. Eighteen major and 28 minor hepatic resections were carried out. Significantly more major resections were carried out in the sequential treatment group. Mean hospital stay was 11 days and 20 percent of patients had complications, with no differences between groups. Survival at one, three and five years was 75, 45 and 36 percent in the simultaneous treatment and 76, 49 and 29 percent in the sequential treatment group (with no significant differences between groups). Conclusions: In this group of patients no differences in complications or survival were observed when liver metastases were treated simultaneously or sequentially. However groups were not homogeneous.

Introducción: Existen distintas estrategias para el tratamiento de las metástasis hepáticas de origen colorrectal sincrónicas (MHCRS): cirugía secuencial, según respuesta a quimioterapia, intervención simultá-nea del tumor y las metástasis o cirugía hepática previa al tumor primario; el uso de una u otra estrategia es aún controvertido. Objetivo: Comparar la morbimortalidad y supervivencia en dos grupos de pacientes con MHCRS intervenidos de forma simultánea versus secuencial. Pacientes y Métodos: Definimos las MHCRS como aquellas que se diagnostican antes o durante la intervención del tumor primario. Se comparan dos grupos de pacientes con MHCRS, 25 sometidos a intervención simultánea (grupo 1) y 51 tras quimioterapia (intervención secuencial: grupo 2). La cirugía hepática la realizó el mismo cirujano. Revisamos datos del paciente, del tumor primario, intervención quirúrgica, transfusión perioperatoria, morbimortalidad y supervivencia. Resultados: 76 pacientes, con edad media de 62,79 +/- 11,3 años. El número de metástasis y la invasión ganglionar del tumor primario fueron mayores en el grupo 2 de forma estadísticamente significativa. Índice de resecabilidad: 77,6 por ciento: 18 resecciones hepáticas mayores y 28 menores, con diferencias significativas entre ambos grupos (p = 0,05). La estancia media (10,89 días), Índice de morbilidad (19,7 por ciento) y supervivencia actuarial a 1,3 y 5 años fueron similares (75 por ciento, 45 por ciento y 36 por ciento en el grupo 1 y de 76 por ciento, 49 por ciento y 29 por ciento en el grupo 2). Mortalidad: 1,6 por ciento. Conclusiones: Las MHCRS pueden ser intervenidas de forma simultánea al tumor primario en pacientes seleccionados siempre que el equipo sea especializado. La morbimortalidad y la supervivencia son similares tanto en la intervención simultánea como en la secuencial.
