Stevens-Johnson syndrome/toxic epidermal necrolysis in an orthotopic liver transplant recipient: a case report.

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare spectrum of acute, mucocutaneous drug reactions characterized by epidermal necrosis of the skin and mucous membranes with progressive multiorgan failure. Cutaneous presentation of SJS/TEN is similar to that of acute graft-versus-host disease, creating a diagnostic dilemma in solid-organ transplant recipients presenting with diffuse, erythematous eruptions, skin sloughing, and systemic sequelae, reflective of both diseases. This case report details a 48-year-old woman post-orthotopic liver transplantation (OLT) who developed a diffuse, painful, morbilliform rash with progressive desquamation, along with corresponding pathological analysis indicative of SJS/TEN. There are few documented reports of SJS/TEN in solid-organ transplant recipients, and this case illustrates successful intervention and resolution of SJS/TEN in an OLT recipient while managing intraabdominal sepsis and an episode of acute rejection. Despite its rarity, prompt diagnosis of SJS/TEN and the implementation of tailored therapeutic strategies are crucial in the care of solid-organ transplant recipients.

Successful kidney transplantation in a small child with end-stage renal disease due to angiotensin receptor blocker fetopathy and atretic inferior vena cava.

Kidney transplantation is the treatment of choice in pediatric patients with end-stage renal disease. This population presents technical challenges particularly in those less than 20 kg due to anomalous anatomy, vascular access issues prior to transplantation, and a generally small size for age. Standard allograft outflow is usually achieved utilizing the iliac veins or IVC. When use of the iliocaval system is not feasible, alternative anastomosis must be considered. Herein, we report a case of a pediatric kidney transplantation where successful allograft outflow was achieved using the SMV when he was found to have an atretic IVC intraoperatively. In this setting, use of the portal system was required to achieve adequate allograft outflow. We created a donor iliac graft for added length to anastomose the renal vein with the SMV. In the setting of IVC occlusion with poor drainage, we utilized a patent vessel with larger caliber for outflow to reduce the risk of high venous pressures, allograft failure, venous rotation, and thrombosis. We conclude that the SMV may serve as an alternative outflow tract in the small pediatric patient and provides the vessel caliber needed to reduce the risks of complications.
