Tongue reconstruction was performed using a deep inferior epigastric perforator (DIEP) free flap in a 6‐year‐old girl with undifferentiated sarcoma of the tongue. After hemi‐glossectomy with upper neck dissection, a 3‐lobed DIEP free flap was used for the reconstruction. Donor site was closed primarily with suturing umbilicus in proper position. No flap loss, leakage, or infection occurred. Postoperatively, the patient was able to consume a normal diet without difficulty or aspiration and displayed good speech function. No donor site morbidity, e.g., herniation or bulging, was observed, and the patient was able to perform their normal daily activities. DIEP flaps provide a pliable skin paddle, an adequate amount of adipose tissue, and reduced donor site morbidity, even in children. We did not have any difficulty harvesting the DIEP flap or with the microvascular anastomosis. We consider DIEP free flaps to be the ideal option for pediatric tongue reconstruction. © 2013 Wiley Periodicals, Inc. Microsurgery 33:487–490, 2013. 相似文献

Computational fluid dynamics (CFD) studies on cerebral aneurysms have attempted to identify surrogate hemodynamic parameters to predict rupture risk. We present a case of bilateral mirror image aneurysms, one of which ruptured soon after imaging. Wall shear stress values of the ruptured aneurysm changed by 20–30 % after rupture because of change in the aneurysm shape. Findings from our case suggest that CFD studies comparing unruptured and ruptured aneurysms may not yield valid estimation on aneurysm rupture risk because of changes in aneurysm shape after rupture. Changes in aneurysm shape after rupture should be considered in CFD research. 相似文献

We previously reported that in p53
+ / − mice that had been given a whole-body dose of 3 Gy at 8 weeks of age, p53-dependent delayed effects of radiation, as manifested in T-cell receptor (TCR) variant fractions (VF) instability in mouse splenocytes, were biphasic, namely, induction of TCR-VF mutation reappeared at 44 weeks. The manifestation of the delayed effects and the measures of biological markers varied according to the timing of irradiation. We also reported that the decrease in function of the p53 gene was related to the effects of a delayed mutation. In the present study, we investigated the functions and mutations of the p53 gene in old age for p53
+ / − mice following irradiation at various ages. p53
+ / − mice were given a whole-body dose of 3 Gy at 8, 28 or 40 weeks of age. There were significant differences for all variables tested at 8 weeks of age. This was similarly the case for mice irradiated at 28 weeks of age, in which there were also significant differences in TCR VF and the percentage of apoptosis. In mice irradiated at 40 weeks of age, there were significant differences for all considered variables except for the p53 allele. We demonstrated that the different patterns of delayed mutation of the p53 gene at 56 weeks of age depended on the age at which mice had undergone 3-Gy whole-body irradiation. Our conclusions are limited to variation in p53-dependent delayed effects according to the time of irradiation. 相似文献
