Introduction Placental mesenchymal dysplasia is a rare vascular disease associated with intrauterine growth restriction, fetal demise as well as Beckwith-Wiedemann syndrome. Some neonates present hematologic abnormalities possibly related to consumptive coagulopathy and hemolytic anemia in the placental circulation. Case report We present a case of placental mesenchymal dysplasia in a fetus wit...

Rearrangements within the chromosome 11q13 region are frequent in hematologic malignancies. 50% of 75% of mantle cell lymphomas (MCLs) carry a translocation t(11;14) (q13;q32). Using Southern blot analysis, a BCL1 breakpoint can be detected in approximately 50% of MCLs. It is not known whether other MCLs harbor also breakpoints at 11q13. Breakpoints in this region not involved in t(11;14), are ...

We studied over 17,000 peripheral blood counts, accumulated during hematologic surveillance from 1940 through 1975, from a cohort of 459 benzene-exposed workers. Linear regressions demonstrated significant decreases in white and red cell counts, as well as hemoglobin, for workers exposed during the 1940s, without persistent trends over the ensuing 25 years. Strongly positive correlations were o...

Sepsis with acute organ dysfunction (severe sepsis) results from a systemic proinflammatory and procoagulant response to infection. Organ dysfunction in the patient with sepsis is associated with increased mortality. Although most organs have discrete anatomical boundaries and carry out unified functions, the hematologic system is poorly circumscribed and serves several unrelated functions. Thi...

The aim of this study was to characterize the metabolic disturbance associated with the skeletal myopathy resulting from extreme weight loss in anorexia nervosa. Muscle function was examined in eight female patients with severe (40%) weight loss due to anorexia nervosa and histologically confirmed myopathy. A wide range of biochemical and hematologic investigations were carried out, including s...

OBJECTIVES To evaluate the yield and safety of transthoracic fine-needle aspiration (FNA) in the diagnosis of pulmonary disease in patients with hematologic malignancy. DESIGN Retrospective chart review. SETTING Tertiary-care medical center. PATIENTS Sixty-seven patients with a hematologic malignancy or after bone marrow transplantation (BMT) for a hematologic malignancy who underwent a t...

BACKGROUND AND PURPOSE Combined methylmalonic aciduria and homocystinuria (MMA-HC) is caused by impaired hepatic conversion of dietary cobalamin to methylcobalamin and adenosylcobalamin, resulting in decreased activity of methylmalonyl-CoA mutase and methionine synthase. Patients with the early-onset variety present within 12 months of age with severe neurologic, hematologic, and gastrointestin...
