Approach to dysglycemia: Do we need to treat impaired glucose tolerance and impaired fasting glucose?

AbstractImpaired glucose tolerance (IGT) and impaired fasting glucose (IFG) are not only a surrogate for the state of insulin resistance but are also associated with the microvascular and macrovascular complications traditionally linked to diabetes. They predict an increased risk for death and morbidity due to cardiovascular disease.There is growing evidence that early detection of this state of “pre-diabetes” enables us to limit these recognized complications and perhaps to halt the progression to diabetes. For all pre-diabetes patients’ life style modifications, emphasizing modest weight loss & moderate physical activity are strongly recommended. Pharmacological intervention may also be necessary. Many studies have shown several drugs, both antidiabetic and nonhypoglycemic agents to be useful. If pharmacological treatment is required, Metformin is considered the first choice because of its safety, tolerability, efficacy and low cost

Clinical and inheritance profiles of Kallmann syndrome in Jordan

BACKGROUND: Proper management of patients with Kallmann syndrome (KS) allows them to attain a normal reproductive health. The purpose of this study is to demonstrate the presentation modalities, phenotypes and the modes of inheritance among 32 patients with Kallmann syndrome in Jordan. Recognition of the syndrome allows for prompt proper management and provision of genetic counselling. SUBJECTS: Over a period of five years (1999–2004), the clinical and inheritance profiles of 26 male and 6 female patients with Kallmann syndrome from 12 families were evaluated at the National Center for Diabetes, Endocrinology and Genetics in Jordan. RESULTS: The patients belonged to twelve Jordanian and Palestinian families and their age at presentation ranged from 4 – 46 years. Nine boys aged 4–14 years presented with cryptorchidism and microphallus, all other males presented with delayed puberty, hypogonadism and/or infertility. The main presentation among six female patients was primary amenorrhea. Intrafamilial variability in clinical phenotype was specifically evident for renal abnormalities and sensorineural hearing impairment. Familial KS was diagnosed in 27 patients belonging to five families with the X-linked mode of inheritance and two families with the autosomal recessive mode of inheritance. CONCLUSIONS: (1) the majority of cases in this study represented the X-linked form of KS, which might point to a high prevalence of Kal 1 gene in the population. (2) Genetic counselling helps these families to reach a diagnosis at an early age and to decide about their reproductive options. (3) Children presenting with cryptorchidism and microphallus in our population should be investigated for KS
