Passenger Lymphocyte Syndrome After Simultaneous Pancreas-Kidney Transplantation: A Case Report of an Unusual Cause of Alloimmune Hemolytic Anemia.

BACKGROUND: Passenger lymphocyte syndrome (PLS) is a disease in which the donor's lymphocytes produce antibodies to the red blood cell antigens of the recipient, causing alloimmune hemolysis. CASE REPORT: We report the case of a 39-year-old woman with stage V chronic kidney disease on hemodialysis secondary to poorly controlled diabetes mellitus type 1. She received a simultaneous pancreas-kidney transplant from a cadaver donor. The donor was A- and the recipient was A+ without initial complications with normal renal and pancreatic function, and her hemoglobin (Hb) level was 10.2 g/dL at discharge. Four weeks later she was admitted with acute pyelonephritis of the renal graft, with a Hb level of 7.5 g/dL, creatinine level of 0.7 mg/dL, and glucose level of 80 mg/dL. The study of anemia showed direct polyspecific direct Coombs weakly positive (w/+), presenting 2 alloantibodies against the Rh system: anti-D, anti-E. We increased Prednisone dose to 1 mg/kg/d and then decreased it in a pattern. Eight days after discharge, without transfusion, her Hb level was 9.9 g/dL and then it normalized. CONCLUSIONS: PLS is a very rare condition and should be suspected in the first few weeks after transplantation. In our case anemia was probably due to a residual population of Rh-negative donor cells in the transplanted pancreas-kidney received. It is usually a sudden onset of hemolytic anemia in patients with a solid organ transplant and different Rh or ABO lower incompatibility.

Ortner's syndrome: a case report and review of the literature.

We present a case of a 67-year-old man who was an active smoker, with a clinical history of ischaemic cardiopathy, hypertension, who presented to the emergency room with hoarseness of voice of 2 weeks duration. No other neurological or cardiorespiratory symptoms were found. Physical examination revealed an aortic regurgitation murmur with radial pulse difference between the upper limbs and femoral pulse difference on lower limbs. Laryngoscopy examination revealed a left vocal cord paralysis in the paramedian position, without signs of malignancy. Thoracoabdominal CT angiography was performed to rule out an aortic dissection. CT revealed a dissection in the descending thoracic aortic arch and abdominal aorta. Cardiovascular surgery was consulted and decided to place endoprosthesis at the thoracic and abdominal aortic area. Hoarseness eventually resolved during the following weeks. Ortner's syndrome is described as hoarseness of voice caused by compression of the left recurrent laryngeal nerve of cardiovascular origin.

Werner's syndrome: incidental finding during pregnancy.

Werner's syndrome (WS) is a rare autosomal recessive disorder, characterised by skin changes prematurely during adolescence. An unusual case of WS was found in a 27-year-old pregnant woman who presented to the hospital with a history of uncontrolled hypertension at 32 weeks of gestation. All clinical features corresponding to WS (early aging of skin, hair loss, blurred vision and diabetes type 2) appeared to match with the prospective diagnosis, which was confirmed later with genetic testing. The pregnancy became complicated due to oligohydramnios and therefore a caesarean section was carried out in order to preserve the fetus. Despite all implemented efforts, the patient died intraoperative as a result of cardiac arrest and its complications. Successfully, the newborn survived and it was further investigated to exclude this condition.

A headache presenting in the emergency room, a clinical manifestation of an unfortunate diagnosis (grade III left frontal anaplastic ependymoma with 1p deletion).

An 18-year-old girl presented with a headache and behavioural changes. She was found to have a frontal mass. Neuroimaging revealed an intra-axial mass, located at the left frontal cortical/subcortical region approximately 6×7, 5×7, 5 cm (TxApxL), having a heterogeneous density with cysts and calcification. She had total gross excision of the neoplasm. Histopathological examination revealed an anaplastic ependymoma. Fluorescence in situ hybridisation, a molecular cytogenetic test, reported deletion of 1p without deletion of 19q. The patient had a good postoperative improvement.

Haemobilia due to iatrogenic portobiliary fistula after cholecystectomy.

Haemobilia, defined as bleeding into the biliary tree is a rare condition. We describe a case report of a patient who presented it as a complication of iatrogenic portobiliary fistula, followed after an open cholecystectomy. The patient presented to the emergency department with late onset symptoms of haematemesis and melena a month after surgery. Findings were confirmed by Doppler ultrasound that showed the appearance of intragallbladder mass with high echogenicity representing a blood clot. Also, next to the portal vein and the biliary duct a lesion with mixed blood flow was detected confirming a portobiliary fistula. This case was successfully managed by angiography and selective embolisation.
