Continuous glucose monitoring (CGM) systems are an emerging technology that allows frequent glucose measurements to monitor glucose trends in real time. Their use as a diagnostic tool is still developing and appears to be promising. Combining intermittent glucose self-monitoring (SGM) and CGM combines the benefits of both. Significant improvement in the(More)
In recent years, the issue of osteopenia/osteoporosis in children, adolescents and young adults with thalassaemia major (TM) has attracted much attention because it is a prominent cause of morbidity despite adequate transfusion and iron chelation therapy. The reported frequency of osteoporosis, even in well treated TM patients varies from 13.6% to 50% with(More)
This paper discusses the importance of culture collections in plant pathology and reviews the methods currently available to store cultures. The preservation and maintenance of plant pathogenic fungi in a viable yet stable state for long periods has always been important, because isolates of these fungi can serve as standards for identification of(More)
Rhino-orbital zygomycosis is usually an aggressive, fulminant and, at times, fatal disease that requires urgent medical and surgical treatment. We report a case of rhino-orbital zygomycosis caused by Rhizopus oryzae that developed in a 41-year-old male renal transplant recipient. He was diagnosed in the early post transplant period after anti-rejection(More)
INTRODUCTION Primary hypothyroidism is one of the most frequent complications observed in-patients suffering from thalassemia. We investigated and reviewed the thyroid function in all thalassemic patients attending the Pediatric Endocrine Clinic of Hamad Medical Center, Doha, Qatar during the last 10 years of follow-up. PATIENTS AND METHODS A total of 48(More)
AIM OF THE STUDY To evaluate semen parameters and to assess serum FSH, LH, Testosterone (T) concentrations before and 12 weeks after intravenous iron therapy (800-1200 mg elemental iron therapy - IVI) in adults with iron-deficiency anemia (IDA). MATERIALS AND METHODS We studied 11 eugonadal adults with IDA, aged 40 ± 5 years, due to defective intake of(More)
BACKGROUND Thalassemia major patients with repeated blood transfusion have high prevalence of endocrinopathies due to iron overload. MATERIALS AND METHODS We examined the adrenocortical function in 23 thalassemic patients (10 children and 13 young adults) aged 8-26 years. Serum cortisol and dehydroepiandrosterone sulfate (DHEA-S) concentrations were(More)
A study was conducted to describe the clinical presentation, epidemiology and outcome of imported malaria in patients admitted to Hamad Medical Corporation, Qatar, between 1st January and 31st December 2005. During a one-year study, 81 patients [64 (79%) males and 17 (21%) females] were studied. The median age was 26 years. Most infections were caused by(More)
Myeloproliferative neoplasms are clonal disorders characterized by the presence of several gene mutations associated with particular hematologic parameters, clinical evolution, and prognosis. Few therapeutic options are available, among which interferon α (IFNα) presents interesting properties like the ability to induce hematologic responses (HRs) and(More)
Thalassaemia is one of the most common genetic disorders caused by a reduction of the globin chains leading to chronic haemolytic anaemia from birth. The mainstay of treatment is blood transfusion to maintain adequate levels of the haemoglobin. Iron overload in β-thalassaemia major patients is secondary to multiple blood transfusions and increased iron(More)
