DOI: 10.5581/1516-8484.20110128 Thalassemias are common monogenic disorders caused by partial or complete reduction synthesis of one or more globin chains.(1) The normal concentrations of fetal hemoglobin (Hb F) in adults without Hb alterations range from 0% to 1%.(2) It is known that stimulation of Hb F production is beneficial to homozygous beta-thalassemia individuals(3) and that the XmnI po...

A 23 years old male presented with fluctuating jaundice since age of five years. He was diagnosed to have thalassemia trait along with Gilbert's syndrome. He had disproportionately higher bilirubin concentration for either disorder alone. The importance of the concomitance of these disorders is highlighted.

OBJECTIVE Changing patterns of immigration to North America, along with improved treatment, have altered the clinical spectrum of thalassemia, one of the world's most common genetic diseases. The new demography of the disease, with its widely variable phenotypes, has implications for its diagnosis, counseling, and management. Characterization of the new spectrum of this ancient disease, now pre...

INTRODUCTION Thalassemia is a chronic blood disease, which imposes adverse effects on patients and their families. Parents of such patients, given that they had the thalassemia trait, hold themselves responsible for their children's disease in addition to other difficulties, bear the burden of guilt and hopelessness and worry about the health and future of their children. This study aimed to ex...

this a case report of an iranien jewish young women, who had hypochromic anemia inspitc of incrcscd medullary iron.. this finding lead to the discovery of hb h in one of her sister's and one of her daughters, who (like beta thalassemia trait), but presence of hb h in her sister and daughter, and presence of minimum quantities of bart's hb in her sister.

BACKGROUND Microcytic hypochromic anemia is a common condition in clinical practice, and alpha-thalassemia has to be considered as a differential diagnosis. AIMS This study was conducted to evaluate the frequency of alpha-gene, beta-gene and hemoglobin variant numbers in subjects with microcytic hypochromic anemia. SETTING AND DESIGNS Population-based case-control study in the Iranian popul...

Dr. Köseler and her colleagues reported the presence of δthalassemia in 3 out of 12 patients carrying the β-thalassemia trait with low HbA2 in the recent issue of this journal without giving any explanations for the remaining 9 cases (2012; 29: 289-290) [1]. I wish that they would also look for the presence of αthalassemia, at least in those 9 cases, because this seems to be the more prevalent ...

amelogenesis imperfecta is a group of genetic disorders that affects both the morphology and quality of tooth structure. although the disease entity is primarily associated with abnormalities of dental and oral structures, it has been reported to be associated with a few syndromes. a 9-year-old girl with minor thalassemia referred to the department of pediatric dentistry of the mashhad faculty ...

In the sickle cell syndromes, Hb A2 measurements aid in the differential diagnosis of sickle cell anemia from sickle-beta-thalassemia. The purpose of this study is to assess the Hb A2 levels in samples containing sickle hemoglobin (Hb S) by the use of an automated high performance liquid chromatography system (HPLC-Variant beta-thalassemia Short Program). The blood samples analyzed were from in...
