The combination of radiation and mastectomy reduces the 3-dimensional topography of the breast into a relatively inelastic, 2-dimensional plane. This environment presents specific challenges to aesthetic breast reconstruction with autologous tissue transfer, and a relative sparsity of information exists in the surgical literature on how to address these challenges. Accordingly, this article details a formalized and reproducible approach for flap inset in postradiation breast reconstruction. We outline a novel technique for optimizing the recipient bed and present a sequential flow for contouring the autologous abdominal flap, so that it recreates the individual subunits of an aesthetic breast. 相似文献

BackgroundGlucose and fatty acids comprise the primary substrates for myocardial energy metabolism. The normal myocardium switches toward glucose metabolism in the setting of stress; the inability to affect such a switch is a fundamental mechanism behind “diabetic” or “insulin-resistant” cardiomyopathy. The purpose of this mechanistic study was to evaluate the effects of treatment with the dipeptidyl peptidase (DPP) 4 inhibitor sitagliptin on myocardial glucose uptake in patients with nonischemic cardiomyopathy.Methods and ResultsTwelve nondiabetic subjects with nonischemic cardiomyopathy underwent metabolic testing and assessment of myocardial glucose uptake by 18F-fluorodeoxyglucose positron-emission tomographic/computerized tomographic imaging at baseline and after 4 weeks of sitagliptin therapy. Sitagliptin therapy resulted in a significant increase in myocardial glucose uptake (19% increase; P = .04). Although most patients had at least a slight increase in glucose uptake, there was an overall bimodal response, with 6 patients (“responders”) demonstrating large increases (>20%) in glucose uptake and 6 patients (“nonresponders”) demonstrating <5% increases or slight decreases. Triglyceride–high-density lipoprotein ratios significantly dropped in the 6 responders compared with the 6 nonresponders (P < .02).ConclusionsTherapy with the DPP-4 inhibitor sitagliptin results in increased myocardial glucose uptake in nondiabetic patients with nonischemic cardiomyopathy. 相似文献

Purpose. To evaluate the effectiveness of phacoemulsification with goniosynechialysis in the management of refractory acute angle closure (AAC). Methods. In this prospective, noncomparative interventional case series, patients with AAC who were unresponsive to medical and laser therapy were included. Success was defined as complete if intraocular pressure (IOP) had a drop of at least 30% and was between 6 and 21 mmHg without medication, and qualified if IOP was within that range with medication. Results. A total of 24 patients with a mean age of 56 years (range 39-77) were treated. Mean follow-up time was 15.7±4.2 months (range 6-24). Mean preoperative and last visit IOPs were 34.27±7.23 mmHg and 17.5±3.21 mmHg, respectively (p<0.001). Mean number of glaucoma medication dropped from 3.67±0.48 to 0.63±1.05 (p<0.001). There was a positive correlation between the attack-surgery interval and last visit IOP (p<0.001, r=0.697). There was a negative correlation between the preoperative anterior chamber depth and last visit IOP drop (p=0.03, r=-0.56). Also, a positive correlation was found between the preoperative IOP and last visit IOP drop (p<0.001, r=0.896). At final visit, complete and qualified success was achieved in 17/24 (71%) and 5/24 (21%) cases, respectively. The most common intraoperative and postoperative complications were hyphema and anterior chamber fibrinous reaction, respectively. Conclusions. Phacoemulsification with goniosynechialysis seems to be a safe and effective method for the management of patients with refractory AAC. This procedure can be considered for these patients before proceeding with filtering surgery. 相似文献

Liver transplantation for the treatment of metastatic neuroendocrine tumors (NETs) is radical. Although cure is not impossible,
it is improbable. The reported experience with transplantation for NETs is limited to less than 150 cases with widely varying
results and few 5-year disease-free survivors. We reviewed our experience with transplantation for patients with NETs. Fourteen
symptomatic patients with unresectable NET liver metastases who had failed medical management were listed for transplantation.
Two patients listed for transplantation underwent prior right lobectomies. Three patients were listed but did not undergo
transplantation: one was lost to follow-up, one died 14 months after listing, and one remains waiting over 4 years. Eleven
patients underwent liver transplantation, three with living donor grafts. There were four men (36.4%) and seven women (63.6%)
who had a mean age of 51.2 ± 6.3 years. Three patients had distal pancreatectomies and one patient had a Whipple procedure
at the time of transplantation. There were six nonfunctioning tumors (54.6%), three carcinoid tumors (27.3%), and two (18.2%)
Vipomas. In one patient, with fulminant hepatic failure, the NET was an incidental finding in the explant. The 1- and 5-year
survival among transplanted patients is 73% and 36%, respectively, with a mean follow-up of 34 ± 40 months (range 0 to 119
months). Of the three patients surviving more than 5 years, only one was disease free. In carefully selected patients with
metastatic NETs, liver transplantation may be an appropriate option.
