Vitamin B12 deficiency--need for a new guideline.
OBJECTIVES Many patients with vitamin B12 deficiency do not have anemia or macrocytosis, but the prevalence of B12 deficiency in patients without macrocytosis is not known. METHODS We investigatedExpand

Integrable lattice realizations of conformal twisted boundary conditions
We construct integrable lattice realizations of conformal twisted boundary conditions for s�( 2) unitary minimal models on a torus. These conformal field theories are realized as the continuumExpand

The effects of a self-educating blood component request form and enforcements of transfusion guidelines on FFP and platelet usage. Queen Mary Hospital, Hong Kong. British Committee for Standards in
Despite establishment of transfusion guidelines and feedback intervention, FFP and platelet transfusion were still inappropriate in many clinical situations at our hospital. Many physicians neverExpand

Successful engraftment in two adult patients with severe aplastic anemia using nonmyeloablative conditioning followed by unrelated HLA-mismatched cord blood transplantation.
Umbilical cord blood as an alternative source of hematopoietic stem cells and nonmyeloablative conditioning are very exciting new developments in transplantation. We report here mixed chimerism inExpand

The impact of a gel system on routine work in a general hospital blood bank.
The gel system has been reported to be more sensitive and specific than the conventional tube indirect antiglobulin test (IAT) for antibody screening. However, a major concern about the gel system isExpand

Provision of phenotype-matched blood units: no need for pre-transfusion antibody screening.
BACKGROUND AND OBJECTIVES The Hong Kong government is planning to introduce an electronic smart identity card for all seven million citizens in 2003. If the smart card contains the full red cellExpand

Low frequency of c-kit expression and detection of an aberrant Kit message among Hong Kong Chinese myelogenous leukaemia patients.
The c-kit proto-oncogene encodes a transmembrane tyrosine kinase receptor. It is expressed by the primitive CD34 positive haemopoietic stem cells and interacts with the Kit ligand for signalExpand

Severe ABO Hemolytic Disease of Newborn is Infrequent among Hong Kong Chinese
The reported incidence of severe hemolytic disease of the newborn (HDN) due to ABO incompatibility varies among different racial populations. A higher incidence and severity are observed among BlackExpand

Integrable and conformal twisted boundary conditions for sl(2) A-D-E lattice models
We study integrable realizations of conformal twisted boundary conditions for s�( 2) unitary minimal models on a torus. These conformal field theories are realized as the continuum scaling limit ofExpand
