Leukaemoid reaction with megakaryocytic features in newborns with Down's syndrome.

A leukaemoid reaction was observed in 3 newborns with Down's syndrome. Thrombocytopenia was present in 2, requiring platelets transfusions in 1, and red cell transfusions were necessary in 2 patients. Blast cells characterization by specific monoclonal antibodies showed a prevalence of megakaryoblasts in all 3 cases. This feature was confirmed in 2 of them by the demonstration of platelet peroxidase (PPO) activity under transmission electron microscopy (TEM). A spontaneous remission of the leukaemoid picture was observed after 2-3 months. However, in 1 case a relapse of the myeloproliferative disorder with the same features of the blast cell population was diagnosed after 16 months. Chemotherapy with low-dose Ara-C, started because of a relevant clinical involvement, induced a complete remission.

Effect of long-term GH administration on pituitary-thyroid function in idiopathic hypopituitarism.

Twenty-four euthyroid children with idiopathic pituitary dwarfism were studied. The euthyroid state for seven of these patients was determined by negative physical examinations, normal plasma T4 assays and normal 131I uptakes. For the other children, thyroid function was evaluated with T3 and T4 assays and on the basis of the TRH test. Each of the children was treated with HGH in one of three different ways. The first group (five cases) was given a HGH dose, ranging from 12.4 to 17.2 IU/m2//week. The second and third groups (nine and ten cases, respectively) were treated with 10 and 20 IU/m2/week, respectively. Treatment was carried out for periods ranging from 6 months to 6 years. After no less than 6 months of treatment, and at intervals of 6 months (or some multiple of 6 months) plasma T3 and T4 assays, as well as a TRH test were performed in each patient. In some patients one of the indices was once beyond the upper or lower limit of the normal range (none of the children presented simultaneous abnormal levels of more than one index during the controls). This value, however, returned to within normal limits at the following control. There was no correlation between T3, T4 and TSH with the duration of HGH therapy. There was no significant difference between the groups of children treated with the different HGH doses. These data seem to demonstrate that the risk of inducing an alteration in thyroid function in hypopituitary patients during HGH treatment is very slight, and that the irregularly abnormal thyroid indices observed in some of the children during one of the controls might be an expression of their metabolic status at that moment.

[Neurologic risks caused by perinatal and neonatal problems in a provincial hospital].

The study intends to value results of follow-up of risk neonates hospitalized for the period 1980-88 at Neonatal Intensive Care Unit of Bufalini Hospital Cesena and the course with time of neurologic and neuropsychological alterations, reported to the birth-rate of territory in which operates the Neonatal Intensive Care Unit. The survivor infants attended in follow up have been 419: 63 of neonatal weight less than or equal to 1500 g (group A), 117 of weight 1501-2000 g (group B), 239 of weight greater than 2000 g (group C). The follow-up provided at first 12 months of life a pediatric examination together with motoscopic examination to Milani-Comparetti every two months, at 3 years--4 years and 6 months, 7 years a pediatric examination with evaluation of Intelligence Quotient (N.E.M.I.), at last two months of 1st Primary School evaluation of acquired scholastic learning capacities by reading test of Inizan and calculation test of Meljac. Diagnosis of cerebral palsy (C.P.) has been always placed at first 12 months of life. All the survivors have been executed pediatric checks as foreseen at first 12 months of life. The subjects with CP are 26 (%); of these 13 have an I.Q. less than or equal to 70. The risk to develop CP seems to depend strictly by hypoxic perinatal stress (21/26 infants). The type of CP seems to be conditioned by neonatal weight, in particular as regards spastic paraplegia (10/12 infants of weight less than or equal to 2000 g), but hemiplegia and tetraplegia are with equality distributed (7/14 infants of weight less than or equal to 2000 g).(ABSTRACT TRUNCATED AT 250 WORDS)
