Oncological resection of lung cancer invading the aortic arch In full thickness using a non-fenestrated endograft.

T4 lung cancer invading the full thickness of the aortic arch was completely removed in a 78-year-old lady using a non-fenestrated endograft closing the left subclavian artery origin without performing surgical revascularization. Left thoracotomy and upper lobectomy with resection of superior segment of the lower lobe and full thickness of the infiltrated aorta was performed without covering the aortic defect. The margins of the specimen were free of tumor. The patient survived 32 months. J. Surg. Oncol. 2016;114:412-415. © 2016 Wiley Periodicals, Inc.

Marked effects of Pilates on the abdominal muscles: a longitudinal magnetic resonance imaging study.

PURPOSE: The study's purpose was to analyze the effects of Pilates on the volume of the rectus abdominis (RA), obliques, and transversus abdominis, with the last two considered conjointly (OT). METHODS: The volume of OT and RA were determined using magnetic resonance imaging in nine nonactive healthy women, before and after 36 wk of a standardized Pilates training program (Modern Pilates). RESULTS: The volume of the dominant OT was increased by 8% (P < 0.05) with training, whereas the nondominant OT volume remained unchanged (+2%, P = 0.58). The total volume of RA increased by 21% after Pilates (P < 0.05) because of a similar increase of dominant and nondominant RA volume (21% and 20%, respectively, P < 0.05). Before Pilates, the volume of the OT was 8% greater in the nondominant compared with the dominant side (P < 0.01). This asymmetry was compensated by Pilates training (2%, P = 0.43). No side-to-side asymmetries in RA muscle volumes were observed either before (2%, P = 0.51) or after (1%, P = 0.81) Pilates. CONCLUSIONS: The present study reveals the existence of asymmetries in the muscles of the abdominal wall in nonactive healthy women. Pilates practice twice a week for 9 months elicits hypertrophy of the abdominal wall muscles, particularly of the RA, and eliminates preexisting asymmetries of the OT. Modern Pilates can be recommended as an effective method to reinforce the muscles of the abdominal wall and to compensate preexisting asymmetric developments.

Large asymmetric hypertrophy of rectus abdominis muscle in professional tennis players.

PURPOSE: To determine the volume and degree of asymmetry of the musculus rectus abdominis (RA) in professional tennis players. METHODS: The volume of the RA was determined using magnetic resonance imaging (MRI) in 8 professional male tennis players and 6 non-active male control subjects. RESULTS: Tennis players had 58% greater RA volume than controls (P = 0.01), due to hypertrophy of both the dominant (34% greater volume, P = 0.02) and non-dominant (82% greater volume, P = 0.01) sides, after accounting for age, the length of the RA muscle and body mass index (BMI) as covariates. In tennis players, there was a marked asymmetry in the development of the RA, which volume was 35% greater in the non-dominant compared to the dominant side (P<0.001). In contrast, no side-to-side difference in RA volume was observed in the controls (P = 0.75). The degree of side-to-side asymmetry increased linearly from the first lumbar disc to the pubic symphysis (r = 0.97, P<0.001). CONCLUSIONS: Professional tennis is associated with marked hypertrophy of the musculus rectus abdominis, which achieves a volume that is 58% greater than in non-active controls. Rectus abdominis hypertrophy is more marked in the non-dominant than in the dominant side, particularly in the more distal regions. Our study supports the concept that humans can differentially recruit both rectus abdominis but also the upper and lower regions of each muscle. It remains to be determined if this disequilibrium raises the risk of injury.

Incidencia de aflatoxinas en alimentos para suinos recolectados de granjas del Estado Aragua (Venezuela) / Incidence of aflatoxines in feed for swine collected from farms of the Aragua State (Venezuela)

Se investigó la incidencia de contaminación con aflatoxina B1 (AF-B1) en muestras de alimentos para suinos, recolectadas mensualmente entre junio de 1985 y junio de 1986 de 18 granjas ubicadas en diferentes zonas del Estado Aragua (Venezuela). De un total de 771 muestras, 10,6 por ciento aparecieron contaminación: 0,8 por ciento contenían concentraciones superiores a 20 e inferiores a 40 ppb, 8,0 por ciento concentraciones iguales o inferiores a 10 ppb y 1,3 por ciento, entre 10 y 20 ppb. Se encontraron diferencias marcadas en la incidencia de contaminación entre alimentos de marcas diversas y, en alimentos de una misma marca, diferencias de acuerdo con la zona o la granja proveniencia de las muestras

Valor de la resonancia magnética en la dermatomiositis juvenil / Value of nuclear magnetic resonance in juvenile dermatomyositis

La dermatomiositis juvenil es una enfermedad multisistémica de etiología desconocida que se caracteriza por una inflamación no supurativa de la piel y el músculo esquelético. La electromiografía y la biopsia muscular confirman el diagnóstico clínico, pero son técnicas invasivas. La resonancia magnética (RM) ha demostrado ser una herramienta útil para el diagnóstico de enfermedades musculares, aunque su especificidad es limitada. Los hallazgos de la RM pueden ser útiles para establecer el diagnóstico de esta enfermedad dentro del contexto clínico. Se presenta un caso clínico compatible con dermatomiositis juvenil y se revisa las aportaciones de la RM en el diagnóstico y seguimiento de la enfermedad (AU)
