Abstract
BACKGROUND:
Previous work has suggested that an increase in the amount of developmentally acquired, dominant arm humeral retrotorsion (D HRT) in the thrower’s shoulder may be a potentially protective mechanism. Although the relationship between HRT and shoulder injuries has been reported, the relationship between HRT and ulnar collateral ligament (UCL) tears in baseball players is not known.
PURPOSE:
To determine whether D HRT and nondominant arm HRT (ND HRT) measurements in baseball players with a UCL tear differ statistically from a matched healthy cohort.
CONCLUSION:
There was a significant increase in mean nondominant arm humeral torsion (ie, less retrotorsion) in the UCL tear group, but there was no significant difference in the mean D HRT between the injured and uninjured groups. A greater HRT side-to-side difference was displayed in the UCL tear group. The extent to which a thrower has developmentally acquired both D HRT and ND HRT may affect elbow UCL tear risk. Furthermore, it is possible that the extent of genetically predisposed ND HRT may influence the throwing-related increase in D HRT.
Resumen
ANTECEDENTES:
Trabajos previos han sugerido que un aumento en la cantidad de retrotrosion humeral brazo dominante (D HRT) adquirida en el desarrollo en el hombro del lanzador puede ser un mecanismo potencialmente protector. Aunque se ha informado de la relación entre la TRH y las lesiones en el hombro, no se conoce la relación entre la TRH y las rupturas del ligamento colateral ulnar (UCL) en los jugadores de béisbol.

PROPÓSITO:
Para determinar si las mediciones de HRT y TH no dominante (HRT) en jugadores de béisbol con un desgarro de UCL difieren estadísticamente de una cohorte sana y emparejada.

CONCLUSIÓN:
Hubo un aumento significativo en la torsión humeral media del brazo no dominante (es decir, menos retrotrosion) en el grupo de desgarro de la UCL, pero no hubo diferencias significativas en la media HRT entre los grupos lesionados y no lesionados. Una mayor HRT lado a lado la diferencia se mostró en el grupo de lágrimas UCL. La medida en que un lanzador ha adquirido desarrollo D HRT y ND HRT puede afectar el codo UCL riesgo de rotura. Además, es posible que la extensión de ND HRT genéticamente predispuesta pueda influir en el aumento relacionado con el lanzamiento en la HRT.

Ultrasonografía. Una herramienta viable para la evaluación de las vías respiratorias
Ultrasonography - A viable tool for airway assessment.
Indian J Anaesth. 2016 Nov;60(11):807-813.
Abstract
BACKGROUND AND AIMS: Accurate prediction of the Cormack-Lehane (CL) grade preoperatively can help in better airway management of the patient during induction of anaesthesia. Our aim was to determine the utility of ultrasonography in predicting CL grade. METHODS: We studied 100 patients undergoing general endotracheal anaesthesia. Mallampati (MP) class, thyromental distance (TMD) and sternomental distance (SMD) were noted. Ultrasound measurements of the anterior neck soft tissue thickness at the level of the hyoid (ANS-Hyoid), anterior neck soft tissue thickness at the level of the vocal cords (ANS-VC) and ratio of the depth of the pre-epiglottic space (Pre-E) to the distance from the epiglottis to the mid-point of the distance between the vocal cords (E-VC) were obtained. CL grade was noted during intubation. Chi-square test was employed to determine if there was any statistical difference in the measurements of patients with different CL grades. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were calculated for the various parameters. RESULTS: The incidence of difficult intubation was 14%. An ANS-VC >0.23 cm had a sensitivity of 85.7% in predicting a CL Grade of 3 or 4, which was higher than that of MP class, TMD and SMD. However, the specificity, PPV and accuracy were lower than the physical parameters. The NPV was comparable. CONCLUSION: Ultrasound is a useful tool in airway assessment. ANS-VC >0.23 cm is a potential predictor of difficult intubation. ANS-Hyoid is not indicative of difficult intubation. The ratio Pre-E/E-VC has a low to moderate predictive value.

Papel del ultrasonido en la vía aérea y endobronquial en medicina perioperatoria
The Role of Airway and Endobronchial Ultrasound in Perioperative Medicine.

Abstract
Recent years have witnessed an increased use of ultrasound in evaluation of the airway and the lower parts of the respiratory system. Ultrasound examination is fast and reliable and can be performed at the bedside and does not carry the risk of exposure to ionizing radiation. Apart from use in diagnostics it may also provide safe guidance for invasive and semi-invasive procedures. Ultrasound examination of the oral cavity structures, epiglottis, vocal cords, and subglottic space may help in the prediction of difficult intubation. Preoperative ultrasound may diagnose vocal cord palsy or deviation or stenosis of the trachea. Ultrasonography can also be used for confirmation of endotracheal tube, double-lumen tube, or laryngeal mask placement. This can be achieved by direct examination of the tube inside the trachea or by indirect methods evaluating lung movements. Postoperative airway ultrasound may reveal laryngeal pathology or subglottic oedema. Conventional ultrasound is a reliable real-time navigational tool for emergency cricothyrotomy or percutaneous dilational tracheostomy. Endobronchial ultrasound is a combination of bronchoscopy and ultrasonography and is used for preoperative examination of lung cancer and solitary pulmonary nodules. The method is also useful for real-time navigated biopsies of such pathological structures.

Abstract
BACKGROUND:
Interest in the direct anterior approach for total hip arthroplasty has increased over recent years; however, the potential for substantial complications exists, especially during the surgeon’s learning curve. We evaluated the change in various metrics to help identify a single surgeon’s learning curve. Additionally, we examined whether the learning curve was different for primarily arthroplasty versus trauma-trained surgeons.
CONCLUSION:
Our data support that surgeons who perform primarily joint arthroplasty will likely have a decreased surgical time, but similar EBL compared to those who include arthroplasty as only a portion of their practice, however, a number of confounding variables do exist, and additional investigation is warranted.
KEYWORDS:

Resumen
ANTECEDENTES:
El interés en el abordaje anterior directo para la artroplastia total de cadera ha aumentado en los últimos años; Sin embargo, existe la posibilidad de complicaciones sustanciales, especialmente durante la curva de aprendizaje del cirujano. Evaluamos el cambio en varias métricas para ayudar a identificar la curva de aprendizaje de un solo cirujano. Además, se examinó si la curva de aprendizaje fue diferente para la artroplastia, en primer lugar, versus trauma cirujanos entrenados.
CONCLUSIÓN:
Nuestros datos apoyan que los cirujanos que realizan principalmente artroplastia articular probablemente tendrán un menor tiempo quirúrgico, pero EBL similar en comparación con aquellos que incluyen artroplastia como sólo una parte de su práctica, sin embargo, existen varias variables de confusión y se requiere investigación adicional .
