Perineal hernias are infrequent complications following abdominoperineal surgeries. These hernias require surgical repair when they become symptomatic by several conventional or reconstructive techniques. The benefits of a full laparoscopic approach and/or the combined approach of a perineal repair of the pelvic floor associated to the laparoscopic placement of a traditional synthetic mesh have been previously demonstrated. In this article, we present the case of a perineal incisional hernia, post-abdominoperineal resection of the rectum after radio chemotherapy, in the neoadjuvant treatment of a rectal adenocarcinoma tumor. An alternative approach, not previously described for the surgical repair of this type of hernia, is presented to assess the feasibility of the suturing repair, and efficacy of a biological acellular porcine collagen implant Permacol(®). A full laparoscopic suturing for the closure of the perineal defect associated to biological mesh reinforcement was successfully undertaken, with good short-term outcomes. [ABSTRACT FROM AUTHOR]

It is important that new technology developed for the consumer marketplace be integrated into the structural dynamics, acoustics, and control area. A new network, the Virtual Instrumentation Test and Analysis Laboratory Network (VITALNET,) is being developed so that international government, university, and industrial sites can be linked to share resources and to cooperate on joint projects.

Fourteen rabbits received an intravitreal iron foreign body and were treated with desferrioxamine. Their electroretinographic (ERG) values were recorded and compared with those of an untreated group. With desferrioxamine treatment a delay of the siderotic damage and preservation of better ERG potentials is observed. [ABSTRACT FROM PUBLISHER]

Donor-transmitted vascular tumors are a rare complication after lung transplantation. A 35-year-old woman underwent bilateral lung transplantation for primary ciliary dyskinesia. Three years post-transplant, a nodule in the right upper lung lobe was detected on routine computer tomography. Wedge resection showed a hemangioma. One year later, two new lung nodules, as well as two liver lesions appeared, and vascular lesions without signs of malignancy were diagnosed on laparoscopic liver biopsies. After switching from tacrolimus to sirolimus, the volume of the lesions significantly decreased. However, two years later, mixed solid tissue lesions developed in both ovaries, while the lung and liver lesions gradually increased in volume again. Histological examination after bilateral salpingectomy was compatible with bilateral angiosarcoma. Tumor analysis by haplotyping and human leukocyte antigen typing showed mixed donor-chimerism, proving that the tumoral lesions in the lungs and ovaries were of donor origin. In retrospect, the donor became brain death following brain surgery complications for a previously biopsy-proven cerebral hemangioma, which is believed to have been a precursor lesion of this vascular malignancy. Our case highlights a unique course of donor-related angiosarcoma, finally diagnosed 6 years after lung transplantation. Donor-origin of tumors detected in solid organ recipients should always be suspected in case of uncommon disease course or histology, and proper tissue-based diagnosis using sensitive techniques should be pursued, given the possible implications for treatment and outcome of other organ recipients in case of multi-organ donation.
