Resection and reconstruction of the chest wall for the radical surgical treatment of malignant soft tissue tumors are currently considered a substantial challenge for thoracic surgeons. We present an unusual case of infantile fibrosarcoma with tropomyosin 3-neurotrophic receptor tyrosine kinase 1 fusion in a 13-year-old patient. The surgical treatment consisted of radical resection of the right posterior chest wall and reconstruction with the use of the STRATOS (Strasbourg Thoracic Osteosynthesis System) titanium rib bridge system. The patient had a favorable postoperative course and received respiratory-ventilatory rehabilitation, adjuvant therapy with chemotherapeutic agents, immunotherapy, and radiotherapy.

Objetivo: Determinar la prevalencia de portadores asintomáticos y sensibilidad antimicrobiana de Staphylococcus aureus en trabajadores del Hospital Regional de Ica. Material y métodos: Estudio de tipo descriptivo transversal realizado en noviembre del 2011. Según muestreo aleatorio simple sin reposición, la muestra fue de 131 trabajadores. Se obtuvieron los datos con la aplicación de una ficha y la extracción de las muestras mediante hisopado, obteniendo 262 cepas de manos y fosas nasales. El aislamiento, identificación y pruebas de sensibilidad se efectuaron según los criterios del Clinical and Laboratory Standars Institute (CLSI). Los datos se procesaron en el programa SPSS, realizando análisis univariado y pruebas de significación estadística. Resultados: La prevalencia de portadores asintomáticos fue de 12,98% en total, 10,7% en manos y 5,3% en fosas nasales. Todos los gérmenes fueron sensibles a: meticilina, cefaclor, ceftazidima, vancomicina y rifampicina. Sólo fueron resistentes algunas cepas de fosas nasales (7,1%) a: oxacilina, dicloxacilina, claritromicina y cloranfenicol. Conclusiones: La prevalencia de portadores asintomáticos de Staphylococcus aureus fue baja. Se observó menor frecuencia de portadores cuando se utilizaban algunas medidas de protección. La resistencia antimicrobiana también fue baja. Se debe realizar un estudio caso-control para identificar los factores de protección. ( Rev. méd. panacea 2011; 1:59-66 ).

Introduction There is currently no universal and uniform pattern of peripheral arterial disease (PAD) in the lower limbs; however, it is influenced by various cardiovascular factors of the individual. The objective of this study was to identify the arteriographic patterns of PAD in the lower limbs according to cardiovascular factors in a Peruvian cohort of patients. Methods This is an analytical, observational, and retrospective study. The arteriographic patterns of PAD in the aortoiliac segment were analyzed with the TransAtlantic InterSociety Consensus (TASC-II) score and the Global Anatomic Staging System (GLASS) for the femoropopliteal (FP), infraopopliteal (IP), and pedial (P) segments in a Peruvian cohort from January 2018 to May 2021. Results 595 patients (833 extremities) were analyzed with a mean age of 67.54 ± 16.39 years, and the main cardiovascular factor was diabetes (65.04%). The patients older than 65 years with GLASS FP 4 (p = 0.042), IP 0 (p = 0.004), and P2 ( p = 0.047) presented significant findings: in men and women with GLASS IP 4 ( p = 0.031) and P 2 ( p = 0.045); diabetes with TASC-II A ( p = 0.031), GLASS FP 4 ( p = 0.038), IP 4 ( p = 0.009), and P2 ( p = 0.003); dyslipidemia with TASC-II D ( p = 0.027), GLASS FP 4 ( p = 0.038), IP 0 ( p = 0.009), and P0 ( p = 0.003); smoking with TASC-II D ( p = 0.001), GLASS FP 4 ( p = 0.049) and IP 0 ( p = 0.008); chronic coronary disease with GLASS IP 4 ( p = 0.049) and P2 ( p = 0.037); chronic kidney disease with GLASS FP 4 ( p=0.047), IP 4 ( p = 0.004), and P2 ( p = 0.016); and previous amputation history with GLASS IP 4 ( p = 0.015) and P2 ( p = 0.039). The most frequent arteriographic pattern of PAD in the lower limbs of our cohort was TASC-II A, GLASS FP 0 and 4, IP 0, and P2 ( p = 0.047). Conclusion Our work will allow the limb salvage teams to understand the behavior of PAD affectation in the population of our environment, allowing a timely control of cardiovascular risk factors, adequate revascularization planning, and a significant reduction in the risk of loss of limb.
