The active metabolite of vitamin D, 1,25-dihydroxycholecalciferol (1,25(OH)2D3), is produced mainly by the kidney, but there is evidence for extrarenal production in certain circumstances. We studied whether peritoneal macrophages (PM) from CAPD patients were capable of metabolizing 25-OH-D3 to 1,25(OH)2D3. We found that PM were able to metabolize 25-OH-D3(More)
Evaluation of early response during induction therapy for acute myeloid leukemia (AML) is used for prognostication and re-induction strategy, yet the optimal evaluation time point is unknown. Clearance of bone marrow (BM) blasts by day 14 of therapy does not ensure remission; thus, some patients requiring re-induction are neglected. This study aimed to(More)
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) are emerging. In attempt to eradicate CRE colonization, we conducted a semirandomized, prospective, controlled trial using oral nonabsorbable antibiotics. METHODS Consecutive hospitalized CRE carriers were studied. Patients whose rectal isolates were gentamicin sensitive but colistin resistant were(More)
The BCR-ABL1 negative myeloproliferative neoplasms (MPNs) are associated with an increased risk of both venous and arterial thromboembolic events. Thromboses may be the presenting clinical feature of an MPN or may occur during the course of the disease. Treatment comprises anticoagulant and antiaggregant agents as in non- MPN thromboses, and treatment of(More)
We report the case of a 28-year-old previously healthy male who presented with a 1-week history of fever, headache, vomiting, and jaundice. Blood cultures were positive for group G streptococci and transesophageal echocardiography demonstrated vegetations on the aortic valve, leading to a definitive diagnosis of infective endocarditis. The combination of(More)
Hematological malignancies during pregnancy are rare, which results in the absence of large prospective studies. The diagnosis is often delayed due to the symptom similarity to those of pregnancy and the recommendation to avoid imaging studies during gestation. Management of hematological malignancies during pregnancy poses challenges both to the patient(More)
OBJECTIVE The purpose of this study was to investigate the alleged association between thrombophilia and unexplained third-trimester stillbirth. STUDY DESIGN Case subjects were 37 women with a history of a third-trimester unexplained stillbirth. Control subjects were 46 volunteers, group-matched for ethnic origin, with no history of stillbirth, recurrent(More)
Extreme thrombocytosis (ExT) has been associated with an increased bleeding risk in myeloproliferative neoplasm (MPN) patients and is included in the high risk category in treatment guidelines. Treatment of patients with ExT has not been studied in prospective trials. To study physicians’ approaches to ExT, we distributed a web based questionnaire with(More)
BACKGROUND Despite the lack of clinical studies supporting the use of routine surveillance FDG-positron emission tomography (PET) in patients with diffuse large B cell lymphoma (DLBCL) who achieved remission, many centers still use this strategy, especially in high risk patients. Surveillance FDG-PET computed tomography (CT) is associated with a high false(More)
