The use of autologous fat grafting is ideal in breast reconstruction. However, published data on long-term outcomes and instrumental results of fat grafting to the breast are lacking. The purpose of this study was to review the authors' experience of fat grafting, evaluating the effects related to the use of enhanced stromal vascular fraction (e-SVF) and fat grafting with platelet-rich plasma (PRP) in the maintenance of fat volume in breast reconstruction, comparing the results with a control group. Twenty-three patients aged 19-60 years affected by breast soft tissue defects were analyzed at the Plastic and Reconstructive Department of the University of Rome Tor Vergata. Ten patients were treated with SVF-enhanced autologous fat grafts, and 13 patients were treated with fat grafting + platelet-rich plasma. The patients in the control group (n = 10) were treated with centrifuged fat grafting injection according to Coleman's procedure. The patients treated with SVF-enhanced autologous fat grafts showed a 63% maintenance of the contour restoring and of three-dimensional volume after 1 year compared with the patients of the control group treated with centrifuged fat graft, who showed a 39% maintenance. In those patients who were treated with fat grafting and PRP, we observed a 69% maintenance of contour restoring and of three-dimensional volume after 1 year. As reported, the use of either e-SVF or PRP mixed with fat grafting produced an improvement in maintenance of breast volume in patients affected by breast soft tissue defect.

The objective of this study was to compare two different scanning protocols in patients suspected to have multiple trauma using multidetector 16-row computed tomography (CT) to better define scanning time, imaging quality and radiation exposure. Forty-six patients, between March 2004 and March 2005, with suspected multiple trauma (cerebral, spine, chest, abdominal and pelvis) were evaluated with two different protocols: Protocol "A" 26 patients; Protocol "B" 20 patients. Protocol A consists of a single-pass continuous whole-body acquisition (from vertex to pubic symphysis), whereas Protocol B of conventional segmented acquisition with scanning of body segments individually. Both protocols were performed using a multidetector 16-rows CT (Light-Speed 16, General Electric Medical System, Milwaukee, WI, USA) with the same technical factors. Radiation dose was evaluated in two ways: computer tomography dose index (CTDI) = dose measured in central and peripheral region of the subjects as a direct result of a CT section acquisition of T millimeters thick (independent from the two protocols) and dose length product (DLP) = total dose deposited over the length of the acquisition (dependent from the two protocols). Image quality was rated according to the following scores: 1, excellent; 2, good; 3, satisfactory; 4, moderate and 5, poor. The results were compared using Wilcoxon's test to identify significant difference in terms of image quality, scanning time, radiation exposure and presence of artifacts, assuming significance at a p value of <0.05. In the single-pass scanning, DLP was 2.671 mGy x cm and a total scan time of 35 s. In whole-body protocols, we have seen artifacts due to arm adduction in thorax and less image quality in brain. In the conventional segmented study, DLP was 3.217 mGy x cm and a total scan time of 65 s; this protocol offered less extraction capabilities of off-axial on focused images of the entire spine, aorta, facial bones or hip without rescanning. Protocol A revealed a significant decrease in scan time (35 vs 65 min, p < 0.05), time in the CT examination room (21.7 vs 31.6 min.; p < 0.05), and final image analysis (83.7 vs 102.9 min; p < 0.05) and radiation dose compared to protocol B (p < 0.05). No significant difference was found for patient transport time, image reconstruction time and imaging quality. Reconstruction and isotropic reformation of axial image acquired by whole-body, single-pass protocols due to entire spine evaluation, aortic and splanchnic CT angiography eliminate additional studies. The whole-body, single-pass protocols, compared with segmented acquisitions protocols, resulted in a reduced total radiation dose without relevant loss of diagnostic image information.

PRP mixed with fat grafting leads to an improvement in maintaining breast volume in patients affected by breast soft-tissue defects.

Laparoscopic ventral mesh rectopexy using biological mesh for internal rectal prolapse is safe and effective in ameliorating symptoms of obstructed defaecation and faecal incontinence.

Gallbladder agenesis (GA) is a rare congenital anomaly of the biliary system often associated with other congenital abnormalities. Patients become symptomatic in 23% of cases. GA is often misinterpreted as other diseases, therefore, leading to unnecessary surgery. We report a case of congenital GA associated to cystic duct absence and a biliary tract abnormality diagnosed by Magnetic Resonance with Cholangiopancreatography.

Seminal vesicle cysts are a very rare condition and its often associated with ipsilateral renal agenesis. The diagnosis of seminal vesicle cysts may be delayed or missed because of the non-specific symptoms of this condition. This article reports a triad of right renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory duct obstruction (Zinner syndrome) in a 56 years old man.
