ABSTRACT
Endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) has proven to be an effective and minimally invasive tool to diagnose and stage lung cancer. However, its use for the diagnosis of rare mediastinal and lung pathologies has been rarely described. Hereby we describe a retrospective chart review of our EBUS-TBNA database for unusual diagnosis made between July 2012 and October 2016. Those conditions considered unusual for EBUS-TBNA diagnosis were identified and their medical records reviewed.

We tested four types of surgical repair for load to failure and distraction in a bovine model of Achilles tendon repair. A total of 20 fresh bovine Achilles tendons were divided transversely 4 cm proximal to the calcaneal insertion and randomly repaired using the Dresden technique, a Krackow suture, a triple-strand Dresden technique or a modified oblique Dresden technique, all using a Fiberwire suture. Each tendon was loaded to failure. The force applied when a 5 mm gap was formed, peak load to failure, and mechanism of failure were recorded. The resistance to distraction was significantly greater for the triple technique (mean 246.1 N (205 to 309) to initial gapping) than for the Dresden (mean 180 N (152 to 208); p = 0.012) and the Krackow repairs (mean 101 N (78 to 112; p < 0.001). Peak load to failure was significantly greater for the triple-strand repair (mean 675 N (453 to 749)) than for the Dresden (mean 327.8 N (238 to 406); p < 0.001), Krackow (mean 223.6 N (210 to 252); p < 0.001) and oblique repairs (mean 437.2 N (372 to 526); p < 0.001). Failure of the tendon was the mechanism of failure for all specimens except for the tendons sutured using the Krackow technique, where the failure occurred at the knot. The triple-strand technique significantly increased the tensile strength (p = 0.0001) and gap resistance (p = 0.01) of bovine tendon repairs, and might have advantages in human application for accelerated post-operative rehabilitation.

A 74 year old female presented with fever, associated with papules and plaque in her upper and lower extremities. Exams revealed blood leukocytosis and a positive urine culture. Antibiotic therapy was initiated with no clinical response. After 1 week, chest X-ray showed right upper lobe alveolar infiltrate. A skin biopsy of the lesion showed infiltration by neutrophils, consistent with Sweet's Syndrome. Patient's condition progressively worsened, requiring oxygentherapy. Bronchoscopy and bronchoalveolar lavage were normal, transbronchial biopsies suggested lung involvement of Sweet 's syndrome. Antibiotic therapy was stopped. Corticosteroid were started. Therapy resulted in rapid clinical and radiological improvement.
ABSTRACT
Introducción. En roturas parciales del ligamento cruzado anterior (LCA) no existe consenso en relación a la mejor opción de tratamiento. El uso de radiofrecuencia (RF) es una alternativa empleada actualmente. Este tratamiento puede alterar negativamente la resistencia del LCA. Objetivo. Evaluar punto de fallo a carga máxima (PFCM) de muestras de LCA porcinos con lesiones parciales tratados con RF en haz indemne. Métodos. Se estudian dos grupos (N=40); A control y B tratada con RF. Fijamos muestras en equipo de tracción universal PASCO(R) y aplicamos tracción axial continua hasta fallo, registrando fuerza en Newtons (N) necesaria para PFCM. Resultados. PFCM fue A: 1951,9N (1144-2688) y B: 1457,1N (1070-2025) (p <= 0,001). Conclusión. El uso de RF de manera puntual en el haz indemne de secciones del fascículo PL del LCA porcino disminuye el PFCM en forma significativa respecto de las secciones del fascículo PL del LCA porcino sin tratamiento (AU)
Introduction. There is no consensus on the optimal treatment of partial tears in the anterior cruciate ligaments (ACL). Radiofrequency (RF) has been used to treat ACL partial tears. This treatment can be detrimental to ACL strength. Objective. To evaluate the ultimate failure at maximum load (UFML) of porcine ACL with partial tears. Methods. Two groups were evaluated, N=40, A control and B treated with RF. Samples were placed in a PASCO(R) universal traction machine and axial continuous tension was applied until failure; documenting necessary strength in Newtons (N) to produce UFML. Results. UFML for A: 1951,9N (1144-2688) and B: 1457,1N (1070-2025) (P<=.001). Conclusion. RF use for single bundle ACL partial tears treatment compromises the UFML when compared to single bundle ACL parcial tears without RF (AU)
