We hypothesized that prenatal cocaine exposure results in less optimal infant behavior and more impaired maternal-infant interaction in healthy term infants. Infants were evaluated with the Neonatal Behavioral Assessment Scale (NBAS) at days 1-3 and 11-30 of age, and mother-infant pairs with the Nursing Child Assessment of Feeding Scale (NCAFS) at 7-16(More)
Loss of heterozygosity (LOH) of chromosomal regions bearing tumor suppressors is a key event in the evolution of epithelial and mesenchymal tumors. Identification of these regions usually relies on genotyping tumor and counterpart normal DNA and noting regions where heterozygous alleles in the normal DNA become homozygous in the tumor. However, paired(More)
Recovery was produced by a homogeneous flash of light (M2). With M2 absent, correct letter report was a U-shaped curve when plotted against the interval separating the onset of a letter target and the onset of a patterned masking stimulus (M1). With the homogeneous flash of light ed to the stimulus sequence (target + M1 + M2), recovery occurred for all the(More)
OBJECTIVE Extracting medical knowledge from electronic medical records requires automated approaches to combat scalability limitations and selection biases. However, existing machine learning approaches are often regarded by clinicians as black boxes. Moreover, training data for these automated approaches at often sparsely annotated at best. The authors(More)
Primary effusion lymphoma (PEL) is a rare extranodal lymphoma that typically presents in a body cavity in the absence of a detectable tumor mass and that occurs predominantly in immunosuppressed individuals. The neoplastic lymphoid cells are frequently infected with human herpes virus 8 (HHV8), also known as Kaposi sarcoma herpes virus (KSHV). We describe(More)
Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Lymphomas may clinically, radiologically, and morphologically mimic both benign and neoplastic conditions. We describe two cases of lymphoid malignancies predominantly involving the breast, both presenting diagnostic dilemmas. The first case, ALK-negative anaplastic large-cell(More)
OBJECTIVE Pathology reports are rich in narrative statements that encode a complex web of relations among medical concepts. These relations are routinely used by doctors to reason on diagnoses, but often require hand-crafted rules or supervised learning to extract into prespecified forms for computational disease modeling. We aim to automatically capture(More)
Bing-Neel syndrome (BNS) is defined as intracranial involvement of Waldenström macroglobulinemia (WM). Few cases of orbital involvement have been reported. A 51-year-old man with a history of WM developed bilateral orbitopathy and optic neuropathy. Orbital biopsy, cerebrospinal fluid studies, and neuroimaging confirmed the diagnosis of BNS involving the(More)
We have retrospectively reviewed toxicities and response of a cohort of primary central nervous system lymphoma (PCNSL) patients treated with high dose parenteral methotrexate (MTX) monotherapy without whole brain radiation. From The Massachusetts General Hospital (MGH) Cancer Registry, active since 1946, we selected all immunocompetent patients with(More)
Waldenström macroglobulinemia, a condition that most commonly occurs in lymphoplasmacytic lymphoma, typically manifests with diffuse lymphadenopathies, cytopenias, and a markedly elevated erythrocyte sedimentation rate. Peripheral neuropathy occurs in nearly half of patients with this condition, and hyperviscosity-related nervous system disorders are(More)
