Beta-thalassemia is due to a defect in the synthesis of the beta-globin chains, leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia. The spectrum of thalassemias is wide, with one end comprising thalassemia minor, which consists of a mild hypochromic microcytic anemia with no obvious clinical manifestations, while on the other(More)
Non-transfusion-dependent thalassaemia (NTDT) refers to all thalassaemia disease phenotypes that do not require regular blood transfusions for survival. Thalassaemia disorders were traditionally concentrated along the tropical belt stretching from sub-Saharan Africa through the Mediterranean region and the Middle East to South and South-East Asia, but(More)
BACKGROUND Surgical residency training aims to prepare the surgical resident to become an independent practitioner of surgery. Because surgical residency training remains the sole educational channel to prepare surgeons for independent practice, our study aimed to explore the effect of resident involvement in surgery across a broad spectrum of surgical(More)
INTRODUCTION Taurodontism is an aberration in tooth morphology characterized by vertically enlarged pulp chambers, apical displacement of pulp floors, and short roots. So far in the literature, no more than 8 taurodonts have been reported in 1 patient. The aim of this case report was to describe the endodontic management of a hypertaurodont maxillary second(More)
The term Nontransfusion dependent thalassaemia (NTDT) was suggested to describe patients who had clinical manifestations that are too severe to be termed minor yet too mild to be termed major. Those patients are not entirely dependent on transfusions for survival. If left untreated, three main factors are responsible for the clinical sequelae of NTDT:(More)
BACKGROUND The problem of iron-overload observed in thalassemia patients can be overcome using chelating agents such as deferiprone (Ferroprox(®) ), deferasirox (Exjade(®) ) and deferoxamine (Desferal(®) ). Although these drugs can be used as monotherapy, combined therapy, especially deferiprone with deferoxamine, has led to promising outcomes in various(More)

Tregs hold great promise as a cellular therapy for multiple immunologically mediated diseases, given their ability to control immune responses. The success of such strategies depends on the expansion of healthy, suppressive Tregs ex vivo and in vivo following the transfer. In clinical studies, levels of transferred Tregs decline sharply in the blood within(More)
To the Editor, Ovarian vein thrombosis (OVT) is a rare complication of pregnancy that mainly affects women in their 3rd or 4th decade. Numerous etiologies have been proposed, including ones of idiopathic origin. Early therapy with anticoagulants can be lifesaving; hence, a high index of suspicion is important in order to avoid serious complications such as(More)
The increase in survival rate of β-thalassemia (β-thal) patients allowed for the appearance and manifestation of several complications in almost every organ system. Priapism in β-thal patients is rarely reported in the literature. We herein report and investigate the occurrence of two cases of priapism in two young patients with β-thal intermedia (β-TI).(More)
