Clostridium perfringens, sometimes known as Clostridium welchii, was discovered independently during 1892 and 1893 by Welch, Frankel, "Veillon and Zuber.^ This organism is a saprophytic inhabitant of the intestinal tract, and may be a harmless saprophyte of the female genital tract occurring in the vagina in 4-6 per cent of pregnant women. Clostridial organisms occur in great numbers and distribution throughout the world. Because of this, they are very common in traumatic wounds. Very few species of Clostridia, however, are pathogenic, and still fewer are capable of producing gas gangrene in man. -

Current methods of establishing these two factors are cumbersome and/or prone to errors. The throughput capability of next generation sequencing (NGS) makes it ideal for simultaneous interrogation of the many genes of interest in SCD. This study was designed to confirm the diagnosis in patients with HbSS and Sβ-thalassemia, identify any ß-thal mutations and simultaneously determine the ßS HBB haplotype. Illumina Ampliseq custom DNA panel was used to genotype the DNA samples. Haplotyping was based on the alleles on five haplotype-specific SNPs. The patients studied included 159 HbSS patients and 68 Sβ-thal patients, previously diagnosed using high performance liquid chromatography (HPLC). There was Citation: Adekile, A.; considerable discordance between HPLC and NGS results, giving a false +ve rate of 20.5% with a S Akbulut-Jeradi, N.; Al Khaldi, R.; sensitivity of 79% for the identification of Sβthal. -

Clapp, M.D., Chief, Hematology Section, Gainesville VAMC; Consultants: Neil S. Harris, M.D., Director, Laboratory Hematology/Coagulation, University of Florida and Shands Hospital and Raul C. Braylan, M.D., Director, Hematopathology, University of Florida and Shands Hospital 1. Description of the Rotation: In this rotation, the resident will gain experience in laboratory hematology, which will include (1) peripheral blood studies to evaluate a variety of hematologic disorders, including anemias, lymphoproliferative and myeloproliferative disorders and leukemias. The emphasis on a multidisciplinary approach to diagnose hematologic disorders (including correlation of the peripheral blood studies with bone marrow and lymph node studies) provides an opportunity for the resident to also gain additional experience in (2) traditional histopathology, (3) immunohistochemistry, (4) electron microscopy, (5) protein electrophoresis, (6) flow cytometry, (7) cytogenetics and (8) molecular genetics which may be performed on the peripheral blood, bone marrow or lymph nodes of patients. The residents will acquire valuable experience by independently performing some bone marrow procedures. In addition, the resident will gain experience in coagulation testing. The residents will become familiar with the instrumentation in the hematology laboratory, including the operating principles and trouble-shooting (medical knowledge). The availability of assembled case study sets and reading materials (medical knowledge) will enhance the resident’s experience. Participation in CAP surveys, continuing education and hematology conferences is a component of the rotation (practice-based learning). Management issues and computer applications will be discussed (practice-based learning). As appropriate to the individual case or consultation under review, the ethical, socioeconomic, medicolegal and cost-containment issues will be reviewed and discussed. -

Section 8: Hematology CHAPTER 47: ANEMIA
Section 8: Hematology CHAPTER 47: ANEMIA Q.1. A 56-year-old man presents with symptoms of severe dyspnea on exertion and fatigue. His laboratory values are as follows: Hemoglobin 6.0 g/dL (normal: 12–15 g/dL) Hematocrit 18% (normal: 36%–46%) RBC count 2 million/L (normal: 4–5.2 million/L) Reticulocyte count 3% (normal: 0.5%–1.5%) Which of the following caused this man’s anemia? A. Decreased red cell production B. Increased red cell destruction C. Acute blood loss (hemorrhage) D. There is insufficient information to make a determination Answer: A. This man presents with anemia and an elevated reticulocyte count which seems to suggest a hemolytic process. His reticulocyte count, however, has not been corrected for the degree of anemia he displays. This can be done by calculating his corrected reticulocyte count ([3% × (18%/45%)] = 1.2%), which is less than 2 and thus suggestive of a hypoproliferative process (decreased red cell production). Q.2. A 25-year-old man with pancytopenia undergoes bone marrow aspiration and biopsy, which reveals profound hypocellularity and virtual absence of hematopoietic cells. Cytogenetic analysis of the bone marrow does not reveal any abnormalities. Despite red blood cell and platelet transfusions, his pancytopenia worsens. Histocompatibility testing of his only sister fails to reveal a match. What would be the most appropriate course of therapy? A. Antithymocyte globulin, cyclosporine, and prednisone B. Prednisone alone C. Supportive therapy with chronic blood and platelet transfusions only D. Methotrexate and prednisone E. Bone marrow transplant Answer: A. Although supportive care with transfusions is necessary for treating this patient with aplastic anemia, most cases are not self-limited. -
BPS White Paper
BOARD OF PHARMACY SPECIALTIES WHITE PAPER Five‐Year Vision for Pharmacy Specialties Approved by the BPS Board of Directors on January 12, 2013 © Copyright 2013, Board of Pharmacy Specialties Introduction The Joint Commission of Pharmacy Practitioners’ (JCPP) Future Vision of Pharmacy Practice 2015 states, “Pharmacists will be the healthcare professionals responsible for providing patient care that ensures optimal medication therapy outcomes.” i As the scope of pharmacy practice evolves to meet the complex medication‐related needs of patients, board certification is critical to assure stakeholders of the level of knowledge and skills of pharmacists who provide direct patient care. The Board of Pharmacy Specialties (BPS) acknowledges the support and collaboration of many national pharmacy organizations in this pursuit and assumes the responsibility for recognition of pharmacy specialization through board certification.ii,iii, iv In assuming this responsibility, BPS also acknowledges the pharmacist’s role in direct patient care as it continues to evolve against a backdrop of many unknowns such as changing health care delivery systems and payment models in which the role of government and the private sector are in a state of flux. Whatever changes come to fruition in the delivery of health care, BPS must move forward in a flexible manner that meets its mission to improve patient care by promoting the recognition and value of specialized training, knowledge, and skills in pharmacy and specialty board certification of pharmacists. v This white paper adds focus and clarity to how BPS will approach the board certification of pharmacist specialists over the next five years. This timeline is critical as the goal will be to create a scalable foundation on which to build future board certification activities for pharmacists. -
PHYSICIAN-SCIENTIST [MD/PHD] Who Better to Study Disease Than Those Who Know It Intimately? WHAT IS a PHYSICIAN SCIENTIST?
PHYSICIAN-SCIENTIST [MD/PHD] Who better to study disease than those who know it intimately? WHAT IS A PHYSICIAN SCIENTIST? A physician scientist is a unique clinician who is part of a small cadre of physicians who usually work in academic health science centers and have a high impact on health care through discovery, translational and clinical research, and clinical practice. A physician scientist in Pathology and Laboratory Medicine is a laboratory physician who is trained in both scientific biomedical investigation and in pathology and/or laboratory medicine, often with clinical subspecialty training. On one hand, the physician scientist brings the rigors of scientific investigation into the patient care arena and on the other, the physician scientist’s contact with disease brings clinically relevant questions into the research arena to drive investigations into pathogenesis, prevention, diagnosis, prognosis, and treatment of disease. asip.org/CareerPath/ MEET ADEL MAHMOUD, MD, PHD P HYSICIAN .

Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease Bone Marrow (Stem Cell) Transplant
Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease 1 Produced by St. Jude Children’s Research Hospital Departments of Hematology, Patient Education, and Biomedical Communications. Funds were provided by St. Jude Children’s Research Hospital, ALSAC, and a grant from the Plough Foundation. This document is not intended to take the place of the care and attention of your personal physician. Our goal is to promote active participation in your care and treatment by providing information and education. Questions about individual health concerns or specifi c treatment options should be discussed with your physician. For more general information on sickle cell disease, please visit our Web site at www.stjude.org/sicklecell. Copyright © 2009 St. Jude Children’s Research Hospital How did bone marrow (stem cell) transplants begin for children with sickle cell disease? Bone marrow (stem cell) transplants have been used for the treatment and cure of a variety of cancers, immune system diseases, and blood diseases for many years. Doctors in the United States and other countries have developed studies to treat children who have severe sickle cell disease with bone marrow (stem cell) transplants. How does a bone marrow (stem cell) transplant work? 2 In a person with sickle cell disease, the bone marrow produces red blood cells that contain hemoglobin S. This leads to the complications of sickle cell disease. • To prepare for a bone marrow (stem cell) transplant, strong medicines, called chemotherapy, are used to weaken or destroy the patient’s own bone marrow, stem cells, and infection fi ghting system.
