Synchronous Primary Central Nervous System and Pulmonary Lymphoma in a 7-Year-Old Female with Unspecified T-Cell Immunodeficiency.

Primary central nervous system lymphoma (PCNSL) is rare in children with immunocompromise as an important risk factor. A 7-year-old girl with unspecified T-cell immunodeficiency presented with left-sided weakness and was found to have a right-sided frontal lobe mass on imaging. The mass was resected; histopathology and molecular studies evidenced diffuse large B-cell lymphoma.

Trends in Bone Marrow Sampling and Core Biopsy Specimen Adequacy in the United States and Canada: A Multicenter Study.

Objectives: To assess bone marrow (BM) sampling in academic medical centers.

Methods: Data from 6,374 BM samples obtained in 32 centers in 2001 and 2011, including core length (CL), were analyzed.

Results: BM included a biopsy (BMB; 93%) specimen, aspirate (BMA; 92%) specimen, or both (83%).

Reproducibility of TEG Parameters in Stable Cirrhotics.

Background: Thromboelastography (TEG) has become the standard of care in liver-transplant surgery to identify real-time abnormalities in the coagulation cascade. To our knowledge, no studies have been performed to measure the intrasubject reproducibility of TEG parameters in cirrhotic patients.

Objective: To perform a validation study to determine the reproducibility of TEG in cirrhosis.

Equal 3-Year Outcomes for Kidney Transplantation Alone in HCV-Positive Patients With Cirrhosis.

Kidney transplantation alone in clinically compensated patients with cirrhosis is not well documented. Current guidelines list cirrhosis as a contraindication for kidney transplantation alone. This is an Institutional Review Board-approved retrospective study.

Liver transplant for neuroendocrine tumor metastatic to the liver: literature review and report of extirpation at 16-year recurrence.

New information has demonstrated that there are few long-term disease-free survivors after a liver transplant for neuroendocrine tumors. All studies have limited follow-up to 10 years after a transplant. We present the case of a recurrent metastatic carcinoid in a patient 16 years after an orthotopic liver transplant.

Risk factor assessment of young patients with acute myocardial infarction.

Unlabelled: The Middle East represents an attractive area for young individuals to seek employment, where they are exposed to numerous environmental conditions. The pursuit of a better standard of living has driven hundreds to the Middle East over the recent decades. This influx has also resulted in a predisposition to premature coronary artery disease (CAD).

Primary antiphospholipid syndrome and necrotizing pancreatitis: a diagnostic challenge.

The objective of this study was to report an unusual case of primary antiphospholipid syndrome (APS)-associated severe necrotizing pancreatitis. Since the APS was first recognized in the 1980s, a number of manifestations of the disorder have been described. We report primary APS presenting as severe necrotizing pancreatitis.

Approach to intraoperative consultation for donor liver biopsies.

Context: As demand for organs to treat end-stage liver disease increases, donor livers once deemed only marginally suitable for donation are being considered for transplantation. Pathologists are increasingly being asked to evaluate these livers for acceptability. This article provides guidelines for frozen section evaluation of livers for transplantation.

Porcine intact and wounded skin responses to atmospheric nonthermal plasma.

Thermal plasma is a valued tool in surgery for its coagulative and ablative properties. We suggested through in vitro studies that nonthermal plasma can sterilize tissues, inactive pathogens, promote coagulation, and potentiate wound healing. The present research was undertaken to study acute toxicity in porcine skin tissues.

Severe hepatitis C virus recurrence is nearly universal after donation after cardiac death liver transplant.

Objectives: The rate of hepatitis C virus recurrence after donation after cardiac death liver transplant is not clearly defined.

Materials And Methods: This is a retrospective review of 39 donations after cardiac death-liver transplant recipients. Biopsies were performed at 6, 12, 24, and 36 months for all hepatitis C virus positive donation after cardiac death recipients.

Falsely elevated tacrolimus levels caused by immunoassay interference secondary to beta-galactosidase antibodies in an infected liver transplant recipient.

Careful interpretation of tacrolimus levels is essential to ensure optimal immunosuppressive therapy while avoiding toxicity. Interference with tacrolimus assays may be an underreported event that has the potential to result in negative patient outcomes through unnecessary modifications of therapy. We describe a 55-year-old liver transplant recipient who had falsely elevated tacrolimus levels that led to the eventual disruption of his immunosuppressive therapy and subsequent rejection of his allograft.

Fatal fat embolism in isolated vertebral compression fracture.

Fat embolism after long bone and pelvic fractures as well as orthopedic interventions is a well-documented phenomenon, but it is highly unusual after isolated vertebral fractures. We report a case of fatal fat embolism in a 78-year-old man after an isolated vertebral compression fracture with no related orthopedic intervention. A high index of suspicion is necessary for early diagnosis and successfully treating this unusual complication.

Classical Hodgkin lymphoma concurrently evolving in a patient with marginal zone B-cell lymphoma of the spleen.

Combination of the splenic marginal zone B-cell lymphoma (SMZL) and classical Hodgkin lymphoma (cHL) is extremely rare. We report a unique case with concurrent SMZL and cHL. The patient was a 63-year-old man who presented with fatigue and anemia, showing a splenomegaly and retroperitoneal lymphadenopathy.

Diagnosis of T-cell lymphoma in body fluids: cytologic features and unusual flow cytometric findings.

Objective: To demonstrate the unique morphologic and phenotypic features observed in cases of T-cell lymphomas presenting as effusions.

Study Design: Cytologic slides and flow cytometric histograms of 8 cases of body fluids with T-cell lymphoma were retrospectively reviewed. Morphologic features, flow cytometric histograms and immunophenotypes of the cells were evaluated.
