CONTEXT Modern medical practice involves cost analysis of therapeutic and diagnostic procedures. There are no papers dealing with this theme in relation to forensic autopsies in our country. OBJECTIVE Analysis of direct costs of forensic autopsies. TYPE OF STUDY Cost analysis. SETTING São Paulo Medical Examiner's Central Office. SAMPLE Year 2001 activity. PROCEDURES Routine forensic a...
OBJECTIVE To determine the usefulness of the hour-specific Bhutani et al bilirubin nomogram when applied to infants with Coombs-positive test results. DESIGN Retrospective chart review. SETTING Term nursery and neonatal intensive care unit of a university-affiliated hospital. PATIENTS All infants with A+ or B+ blood type born in our center from September 1, 2006, through August 31, 2008, ...
Folic acid deficiency with the picture of a megaloblastic bone marrow may develop in haemolytic anaemia, and, on the other hand, both vitamin B(12) and folic acid deficiency may produce signs of haemolysis. As the correct interpretation of a positive antiglobulin reaction associated with megaloblastic erythropoiesis is particularly important, the effect of deficiency of vitamin B(12) and folic ...
BACKGROUND Anti-G antibodies are rarely found since anti-D, in combination with anti-C, are difficult to discriminate from anti-G antibodies in routine testing. CASE REPORT A 22-year-old, gravida-3, para-1, woman with blood group A Rh D neg ccddee and known antibody anti-Jk(b), gave birth to her second child. While anti-Jk(b) could not be detected at birth, a new anti-C was found. Antibody sc...
as evidence of autoimmune phenomena. The experimental production of positive antiglobulin tests by drugs and chemical agents, however, has suggested that nonimmunologic mechanisms may also be responsible for protein coating of erythrocytes.2’3 During attempts to produce tumors of the reticuloendothelial system in rats by injection of trypan blue, an anemia, chacacterized by increased ervthrocyt...
We have reviewed the literature to identify and characterize reports of warm-antibody type, autoimmune hemolytic anemia in which the standard direct antiglobulin reaction was negative but a confirmatory test indicated that the red cells were opsonized with antibody. Three principal reasons account for the absence of a positive direct antiglobulin test in these cases: a) IgG sensitization below ...
BACKGROUND A major impediment to the treatment of TB is a diagnostic process that requires multiple visits. Descriptions of patient costs associated with diagnosis use different protocols and are not comparable. METHODS We aimed to describe the direct costs incurred by adults attending TB diagnostic centres in four countries and factors associated with expenditure for diagnosis. Surveys of 22...
Erythrocytes obtained from patients who manifest autoimmune hemolytic anemia can be divided into at least three categories by the nature of their protein coats as determined by direct antiglobulin (Coombs) test: IgG alone, IgG and complement (C), C alone. IgG antibodies were detected by direct Coombs Test at 4#{176}Cbut not at 37#{176}Cin patients of type 3 A.H.A. Experiments at 4, 10, 15, 20, ...
