    Titelübersetzung Perinatal transmission of hepatitis C virus - Santo André Hospital, Leiria 2002-2006.
    Abstract Background: Vertical transmission of hepatitis C virus (HCV) is the main route of infection in children, occurring in few cases (five percent). Current recommendations for HCV screening include first anti-HCV testing at age > 18 months, reducing false positives and false negatives. Positive results must be confirmed by the presence of HCV RNA on two different occasions.
    Aims: To characterize the population of children born to HCV-positive mothers, to identify risk factors for perinatal HCV transmission and to improve the approach to HCV screening.
    Methods: The study was conducted in two phases. An analytic retrospective study enrolling children born to HCV-positive mothers between January 2002 and December 2006 was done, followed by a transversal analysis in order to repeat anti-HCV testing, in cases that didn't meet current recommendations for HCV screening and in those without any HCV screening.
    Results: Fifty-nine children born to HCV-positive mothers in a total of 12 985 births were included, corresponding to a prevalence of 0,45%. A high rate of inadequate pregnancy surveillance, prematurity and low birth weight, mainly in children born to addicted mothers was found. A child with HCV infection without any risk factor for perinatal transmission was found. Among children with negative anti-HCV at age 18 months, half had done anti-HCV prior to nine months of age, all were positive. Children discharged because of negative anti-HCV at nine months of age were called in a second phase of the study, for new anti-HCV at age > 18 months. All were negative.
    Conclusions: Perinatal HCV transmission rate was 2,9%. There was no identified risk factor for perinatal transmission in the single case of HCV infection. A high rate of prematurity, low birth weight and inadequate surveillance of pregnancy was found, with statistical significance to relation with mother addiction. Regarding anti-HCV at age < 18 months, a high rate of false positives but no false negative results were found. This study has enabled the detection and correction of mistakes in the approach to HCV screening.

    Titelübersetzung Growth and puberty in type 1 diabetes mellitus - experience from a pediatric endocrinology unit.
    Abstract Background: Type 1 Diabetes Mellitus (T1DM) is the most common endocrine-metabolic disease in children. It is associated with vascular and neuropathic complications, and may also affect growth and development.
    Objective: To correlate the metabolic control and disease duration with growth and puberty in patients with T1DM followed in a Pediatric Endocrinology Outpatient Clinic.
    Subjects and methods: Retrospective analysis. Sample obtained from patients with T1DM followed in Hospital Santa Maria Pediatric Endocrinology Outpatient Clinic (Lisbon - Portugal) since 1994 until March 2011.
    Inclusion criteria: patients diagnosed before the onset of puberty and who had attained their final height during the follow-up.
    Variables: sex, age, weight and height at diagnosis and final, parents' height, growth velocity, pubertal height gain, age at menarche and metabolic control during puberty.
    Results: 39 patients, 51% female, 82% diagnosed less than five years before puberty. Fifty-four percent presented an average HbA1c between 8-10%, what we considered reasonable. There seems to be a trend towards an inverse association between HbA1c and the maximum speed of growth and pubertal height gain, although not statistically significant. These patients were taller than average at diagnosis (z-score: male 0.9; female: 0.5) and lost height during puberty, yet attained final heights within normal range and matching their target heights.
    Conclusions: Although HbA1c seems to negatively influence maximum growth rate and pubertal height gain, there was no compromise in final height in this group of patients.
