Pulmonary arterial hypertension (PAH) is a cardiopulmonary disease with high mortality. In recent years, it has been recognized that PAH is a multi-organ system disease, involving the systemic circulation, kidneys, skeletal muscles, and the central nervous system, among others. Right heart failure produces congestive hepatopathy, a disease state that has direct consequences on liver biochemistry, histology, and systemic glucose and lipid metabolism. This article aims to summarize the consequences of congestive hepatopathy with an emphasis on liver biochemistry, histology, and PAH-targeted therapy. Furthermore, PAH-specific changes in glucose and lipid metabolism will be discussed.

Incorporating bortezomib and/or lenalidomide in the management of plasmablastic lymphoma is an attractive option due to the reported high response rates. However, concerns about overlapping toxicities can deter clinicians from incorporating these novel agents into chemotherapy. In this case report we describe a patient with plasmablastic lymphoma, who received both lenalidomide and bortezomib as part of upfront treatment for a high-risk plasmablastic lymphoma. After completing intensive chemotherapy, the patient was transitioned to a regimen of daily lenalidomide and biweekly bortezomib to decrease the chance of relapse. This maintenance phase was given for 6 months and was well tolerated. Despite having multiple adverse risk factors, the patient remains in remission, 18 months following diagnosis.

Child development is a process where the level of maturation reached by a child within his age group can be recognized and quantified [1]...

We report a case of a 56-year-old male who presented with several month history of severe low back pain. Physical examination revealed generalized tenderness at his thoracolumbar spine without notable neuromuscular findings. Radiographs revealed a chronic compression fracture of T10 and T11 with anterior height loss. Subsequent magnetic resonance imaging demonstrated multiple lytic lesions in the thoracolumbar spine without canal compromise. During his hospital stay, he developed acute cord compression with loss of motor and sensory levels below T12 and an absence of sphincter tone. The patient was taken for emergent multilevel, posterior decompression and fusion with biopsy of the lesion. Microscopic examination of the tissue in addition to immunohistochemical analysis utilizing CD117-antibody/c-kit revealed gastrointestinal stromal tumor. Further workup revealed the primary tumor to be intra-abdominal and the patient was subsequently begun on adjuvant chemotherapy. Gastrointestinal stromal tumors should be considered in the workup of patients with bone metastasis with an unknown primary malignancy.

Experience with hepatic artery embolization for the treatment of symptomatic hepatic arteriovenous malformations (AVMs) in Rendu-Osler-Weber disease is limited. We report 2 cases of hepatic AVMs that caused mesenteric angina-like symptoms that were treated with embolization. Both patients developed parenchymal and bile duct necrosis, intrahepatic bilomas, and refractory biliary sepsis, subsequently leading to liver failure. We hypothesize that the pathophysiological cause of biliary necrosis in this setting is similar to that which occurs in the setting of hepatic artery thrombosis of the liver allograft. Progressive liver failure in these patients was treated successfully by liver transplantation. Liver transplantation offers definitive therapy by removing the source of ongoing sepsis, restoring normal liver function, and eliminating the intrahepatic AV shunt.
