    Psychiatric Manifestation of Vitamin B-12 Deficiency: An Update

    Get PDF
    Psychiatric manifestations of vitamin B-12 deficiency are reviewed from 1986 to the present. Specific clinical entities reviewed include depression, organic psychosis, obsessive-compulsive disorder, childhood manifestations and dementia. We recommend that consideration be given to B-12 deficiency as an etiological factor in some cases of depression, organic psychosis, certain childhood disorders and dementia. Routine screening of people overage 65 is addressed

    A Resident Initiated Prite Review Course: Trials and Tribulations

    The experience of developing a review course to study for the Psychiatry Resident\u27s In-Training Exam (PRITE) is discussed. Residents in our program felt that the review course was useful with respect to the following: studying for the PRITE; future study for National Boards; and learning of new material. The Psychiatry Resident\u27s In-Training Exam (PRITE) was developed in 1979 as a mechanism to assess the knowledge base of psychiatric residents in a standardized format (1,2,3). The exam was originally designed to simulate the American Board of Psychiatry and Neurology (ABPN) examination, PART I, and has gained widespread acceptance despite questions about its ability to accurately test or reflect the knowledge of the examinee (1,4,5). Principles derived from a system for self-education of residents published by Taylor and Torrey (6) were applied to a review course developed at this institution to improve the knowledge base of each resident with the goal of increasing performance on the PRITE and, ultimately, ABPN exam Part 1. This paper discusses the review course from its conception to final evaluation with views offered from the organizers, the residency director, and the residents taught by this method. It was hypothesized that most participants would feel that the review course was useful in studying for the PRITE exam and that those who had actively participated (i.e., made a handout or gave a lecture) would feel the review course was more useful than those who were passive participants

    Measurement of the B0-anti-B0-Oscillation Frequency with Inclusive Dilepton Events

    The B0B^0-Bˉ0\bar B^0 oscillation frequency has been measured with a sample of 23 million \B\bar B pairs collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we select events in which both B mesons decay semileptonically and use the charge of the leptons to identify the flavor of each B meson. A simultaneous fit to the decay time difference distributions for opposite- and same-sign dilepton events gives Δmd=0.493±0.012(stat)±0.009(syst)\Delta m_d = 0.493 \pm 0.012{(stat)}\pm 0.009{(syst)} ps1^{-1}.Comment: 7 pages, 1 figure, submitted to Physical Review Letter

    A study of time-dependent CP-violating asymmetries in B0J/ψKS0B^{0} \to J/\psi K^{0}_{S} and B0ψ(2S)KS0B^{0} \to \psi(2S) K^{0}_{S} decays

    We present a preliminary measurement of time-dependent CP-violating asymmetries in B0 -> J/psi K0S and B0 -> psi(2S) K0S decays recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The data sample consists of 9.0 fb-1 collected at the Y(4S) resonance and 0.8 fb-1 off-resonance. One of the neutral B mesons, produced in pairs at the Y(4S), is fully reconstructed. The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. A neural network tagging algorithm is used to recover events without a clear lepton or kaon tag. The time difference between the decays is determined by measuring the distance between the decay vertices. Wrong-tag probabilities and the time resolution function are measured with samples of fully-reconstructed semileptonic and hadronic neutral B final states. The value of the asymmetry amplitude, sin2beta, is determined from a maximum likelihood fit to the time distribution of 120 tagged B0 -> J/psi K0S and B0 -> psi(2S) K0S candidates to be sin2beta = 0.12+/-0.37 (stat) +/- 0.09 (syst) (preliminary)

    The two B^0 decay processes B^0 --> D^{*-}pi^+ and B^0 --> D^{*-}l^+nu have been studied by means of a partial reconstruction technique using a data sample collected with the BABAR detector at the PEP-II storage ring. To increase statistics, only the soft pi^- from the decay D^{*-} --> pi^-D^0 was used in association with either an oppositely-charged high-momentum pion or lepton. Events were then identified by exploiting the constraints from the simple kinematics of Y(4S) decays. A clear signature is obtained in each case. The position of the B^0 decay point was obtained from the reconstructed pi^+(l^+)pi^- vertex. The position of the other anti-B^0 in the event was also determined. Taking advantage of the boost given to the Y(4S) system by the asymmetric beam energies of PEP-II, the lifetime of the B^0 meson has been measured from the separation distance between the two vertices along the beam direction. The preliminary results are tau_B0 = 1.55+/-0.05+/-0.07 ps, tau_B0 = 1.62+/-0.02+/-0.09 ps, respectively for the B^0 --> D^{*-}pi^+ and B^0 --> D^{*-}l^+nu channels

    Using a sample of 3.7 x 10^{6} Y(4S) --> B-anti-B events collected with the BABAR detector at the PEP-II storage ring, we search for the electroweak penguin decays B^+ --> K^+e^+e^-, B^+ --> K^+mu^+mu^-, B^0 --> K^{*0)e^+e^-, and B^0 --> K^{*0)mu^+mu^-. We observe no significant signals for these modes and set preliminary 90% C.L. upper limits of B(B^+ --> K^+e^+e^-) 12.5 x 10^{-6}, B(B^+ --> K^+mu^+mu^-) 8.3 x 10^{-6}, B(B^0 --> K^{*0)e^+e^-) 24.1 x 10^{-6}, B(B^0 --> K^{*0)mu^+mu^-) 24.5 x 10^{-6}

    Measurement of branching fractions for two-body charmless B decays to charged pions and kaons at BABAR

    We present preliminary results of a search for charmless two-body B decays to charged pions and kaons using data collected by the BABAR detector at the Stanford Linear Accelerator Center's PEP-II storage ring. In a sample of 8.8 million produced B-anti-B pairs we measure the branching fractions B(B^0 --> pi^+pi^-) = (9.3^{+2.6}_{-2.3}^{+1.2}_{-1.4}) x 10^{-6} and B(B^0 --> K^+\pi^-) = (12.5^{+3.0}_{-2.6}^{+1.3}_{-1.7}) x 10^{-6}, where the first uncertainty is statistical and the second is systematic. For the decay B^0 --> K^+K^- we find no significant signal and set an upper limit of B(B^0 --> K^+K^-) 6.6 x 10^{-6} at the 90% confidence level

    Study of inclusive DS()+/D_S^{(*)+/-} production in B decays and measurement of B0DDS()+B^0 \to D^{*-}D_S^{(*)+} decays using a partial reconstruction technique

    Electron-positron annihilation data collected by the BABAR detector near the Y(4S) resonance are used to study the inclusive decay of B mesons to D_S^(+/-) and D_S^(*+/-) mesons, where the D_S^(+/-) is reconstructed using the decay D_S^(+/-) --> phi pi^(+/-). The production fraction of inclusive D_S^((*)+/-) and the corresponding momentum spectra have been determined. The exclusive decays B^0 --> D^(*-)D_S^((*)+) are observed with a partial reconstruction technique which uses the soft pion from the D^(*+/-) decay in association with the reconstructed D_S^((*)+/-). The beam energy constraint is used to determine the missing mass recoiling against the D_S^(+/-) system, showing a clear signal for this process. From the observed rates, preliminary results for the corresponding branching fractions have been obtained
