Eurotransplant special request for high-urgency status after liver transplantation for hepatocellular carcinoma: a case report.
2008
Hepatic artery thrombosis after liver transplantation remains a major indication for retransplantation. We report the case of a 49-year-old man with a hepatocellular carcinoma in the setting of cirrhosis associated with chronic hepatitis B and C infections who underwent split liver transplantation. The patient experienced a complicated postoperative course, characterized by 2 relaparotomies for necrosis of segment IV, and a late hepatic artery thrombosis, first discovered on postoperative day 20. His subsequent course was characterized by relapsing cholangitis and liver abscesses requiring antibiotics and percutaneous drainage. Transient control of the septic complications allowed for the f…
Case report: Trans-papillary free stenting of the cystic duct and of the common bile duct in a double biliary ducts anastomoses of a right lobe livin…
2021
Abstract Background One of the major issues related to the living donor liver transplantation recipient outcome is still the high rate of biliary complication, especially when multiple biliary ducts are present and multiple anastomoses have to be performed. Case presentation and conclusion We report a case of adult-to-adult right lobe living donor liver transplantation performed for a recipient affected by alcohol-related cirrhosis with MELD score of 17. End-stage liver disease was complicated by refractory ascites, portal hypertension, small esophageal varices and portal gastropathy, hypersplenism, and abundant right pleural effusion. Here in the attached video we described the adult-to-ad…
Differential diurnal variations of anandamide and 2-arachidonoyl-glycerol levels in rat brain.
2004
The endogenous ligands of cannabinoid receptors, also known as endocannabinoids, have been implicated in many physiological and pathological processes of the central nervous system. Here we show that the levels of the two major endocannabinoids, anandamide and 2-arachidonoyl-glycerol (2-AG), in four areas of the rat brain, change dramatically between the light and dark phases of the day. While anandamide levels in the nucleus accumbens, pre-frontal cortex, striatum and hippocampus were significantly higher in the dark phase, the opposite was observed with 2-AG, whose levels were significantly higher during the light phase in all four regions. We found that the activity of the fatty acid ami…
Pregnancy after allogeneic uterus transplantation in the rat: perinatal outcome and growth trajectory
2014
Objective To investigate whether allogeneic uterine grafts in a rat model, with tacrolimus immunosuppression, can harbor pregnancies that result in offspring with normal postnatal growth. Design Experimental animal study. Setting University hospital. Animal(s) Lewis rats as uterus donors and Piebald-Virol-Glaxo rats as recipients. Intervention(s) Animals were allocated to one of the following three groups: allogeneic uterus transplantation with end-to-side anastomosis to the external iliac vessels and immunosuppression with tacrolimus (UT+Tac; n=10); sham surgery and immunosuppression with tacrolimus (Sham+Tac; n=10); or sham surgery (Sham; n=10). The rats were subsequently introduced to ma…
Treatment of relapse after allogeneic stem cell transplantation in children and adolescents with ALL: the Frankfurt experience
2016
Therapy for post-transplant relapse of paediatric ALL is limited. Standardised curative approaches are not available. We hereby describe our local procedure in this life-threatening situation. A total of 101 ALL patients received their first allogeneic stem cell transplantation (SCT) in our institution. After relapse, our primary therapeutic goal was to cure the patient with high-dose chemotherapy or specific immunotherapy (HDCHT/SIT) followed by a second SCT from a haploidentical donor (transplant approach). If this was not feasible, low-dose chemotherapy and donor lymphocyte infusions (LDCHT+DLI) were offered (non-transplant approach). A total of 23 patients suffered a post-transplant rel…
Chronic Therapy With Isosorbide-5-Mononitrate Causes Endothelial Dysfunction, Oxidative Stress and a Marked Increase in Vascular Endothelin-1 Express…
2011
Aims Isosorbide-5-mononitrate (ISMN) is one of the most frequently used compounds in the treatment of coronary artery disease predominantly in the USA. However, ISMN was reported to induce endothelial dysfunction, which was corrected by vitamin C pointing to a crucial role of reactive oxygen species (ROS) in causing this phenomenon. We sought to elucidate the mechanism how ISMN causes endothelial dysfunction and oxidative stress in vascular tissue. Methods and results Male Wistar rats ( n = 69 in total) were treated with ISMN (75 mg/kg/day) or placebo for 7 days. Endothelin (ET) expression was determined by immunohistochemistry in aortic sections. Isosorbide-5-mononitrate infusion caused si…
Modulation by NO of acetylcholine release in the ileum of wild-type and NOS gene knockout mice.
2002
Nitric oxide (NO) inhibits the release of acetylcholine and cholinergic contractions in the small intestine of several species, but no information is available about the mouse ileum. This study examines the effects of NO on the electrically evoked release of [3H]acetylcholine and smooth muscle contraction in myenteric plexus-longitudinal muscle preparations of wild-type mice and of neuronal NO synthase (nNOS) and endothelial NOS (eNOS) knockout mice. The NOS inhibitor N G-nitro-l-arginine (l-NNA) and the guanylyl cyclase inhibitor 1 H-[1,2,4]oxadiazolo[4,3-α]quinoxalin-1-one (ODQ) concentration dependently increased the evoked [3H]acetylcholine release and cholinergic contractions in prepa…
Donor site morbidity of the posterior conchal region.
2009
BACKGROUND The perichondral cutaneous graft (PCCG) from the posterior conchal region is an elegant solution for the coverage of facial defects with particular stability requirements. The donor defect can easily be covered with a transposition flap from the postauricular region. Although this region is a common donor site for skin grafts and has an important supporting function for glasses or hearing aids, little is known about long-term morbidity after graft harvest. OBJECTIVE To assess the morbidity of the posterior concha and the postauricular region in terms of pain, scar formation, and patient satisfaction. MATERIALS AND METHODS A retrospective study of 16 patients who had a PCCG harves…
Equally Interchangeable? How Sex and Gender Affect Transplantation
2019
Organ transplantation as an option to overcome end-stage diseases is common in countries with advanced healthcare systems and is increasingly provided in emerging and developing countries. A review of the literature points to sex- and gender-based inequity in the field with differences reported at each step of the transplant process, including access to a transplantation waiting list, access to transplantation once waitlisted, as well as outcome after transplantation. In this review, we summarize the data regarding sex- and gender-based disparity in adult and pediatric kidney, liver, lung, heart, and hematopoietic stem cell transplantation and argue that there are not only biological but al…
Long-Term Structural and Functional Myocardial Adaptations in Healthy Living Kidney Donors: A Pilot Study
2015
Background and Aims Compensatory renal hypertrophy following unilateral nephrectomy (UNX) occurs in the remaining kidney. However, the long-Term cardiac adaptive process to UNX remains poorly defined in humans. Our goal was to characterize myocardial structure and function in living kidney donors (LKDs), approximately 12 years after UNX. Methods and Results Cardiac function and structure in 15 Italian LKDs, at least 5 years after UNX (median time from donation = 8.4 years) was investigated and compared to those of age and sex matched U.S. citizens healthy controls (n = 15). Standard and speckle tracking echocardiography (STE) was performed in both LKDs and controls. Plasma angiotensin II, a…
