SUMMARY BackgroundSerum radioimmunoassay (RIA) tissue transglutaminase autoantibodies (tTG-Abs) proved to be a sensitive test also during coeliac disease (CD) follow-up. We demonstrated that RIA tTG-Abs could be detected in human saliva.

The group of idiopathic epilepsies encompasses numerous syndromes without known organic substrate. Genetic anomalies are thought to be responsible for pathogenesis, with a monogenic or polygenic model of inheritance. Over the last two decades, a number of genetic anomalies and encoded proteins have been related to particular idiopathic epilepsies and epileptic encephalopathies. Most of these mutations involve subunits of neuronal ion channels (e.g. potassium, sodium, and chloride channels), and may result in abnormal neuronal hyperexcitability manifesting with seizures. However non-ion channel proteins may also be affected. Correlations between genotype and phenotype are not easy to establish, since genetic and non-genetic factors are likely to play a role in determining the severity of clinical features. The growing number of discoveries on this topic are improving classification, prognosis and counseling of patients and families with these forms of epilepsy, and may lead to targeted therapeutic approaches in the near future. In this article the authors have reviewed the main genetic discoveries in the field of the monogenic idiopathic epilepsies and epileptic encephalopathies, in order to provide epileptologists with a concise and comprehensive summary of clinical and genetic features of these seizure disorders.

The fornix appears more involved than CSP alone, as suggested by fornix atrophy observed in MTLE. Even if epilepsy is suggested to be a grey matter disorder, changes in the underlying brain connectivity have an important contribution in seizure generation and diffusion. In addition, the interconnections of medial septal area with hyppocampus, amygdala and entorhinal cortex, have led to the hypothesis of functional limbic epilepsy. In our patients, the role of DTI was not conclusive since the definition of the number of unmyelinated fibers responsible for epilepsy could not be demonstrated probably for a limited number of seizures and for a short period of drug administration.

Early onset sepsis (EOS) is a severe problem affecting very low birth weight (VLBW) infants and is associated with a threefold increased risk of mortality. Although advances in perinatal care have led to improved survival of VLBW infants over recent decades, survival without major neonatal morbidity has not increased. The authors reviewed the current literature on EOS, focusing on the peculiarities concerning risk factors, etiology, diagnosis, treatment and outcome in very low birth weight infants, and on the recent advances in the management of this condition.

The updated Guidelines on Prevention of Perinatal Group B Streptococcal Disease, issued by the Centers for Disease Control and Prevention, actually represent the mainstay in the prevention of neonatal early-onset group B streptococcal (GBS) sepsis. According to these guidelines, patients with possible preterm delivery are screened for GBS colonization and offered intrapartum prophylaxis only if they enter preterm labor or experience preterm premature rupture of the membranes. Nonetheless, the fulfillment of these recommendations seems to be suboptimal in clinical practice, as it is heavily influenced by the knowledge of the colonization status. We report here 2 cases of blood culture-proven, early-onset neonatal GBS sepsis involving preterm infants delivered by mothers who had midtrimester cervical insufficiency and bulging membranes. Midtrimester acute cervical insufficiency strongly predicts preterm delivery. These women are liable to miss intrapartum antibiotic prophylaxis because they typically have shorter labor, and the test results for GBS status are unlikely to be available before delivery. We believe that women with midtrimester cervical insufficiency and bulging membranes should be screened for GBS infection soon after hospital admittance if the gestational age is close to the threshold of fetal viability. A timely diagnosis of GBS colonization may not only increase the number of patients receiving targeted intrapartum antibiotic prophylaxis but would also allow consideration of the administration of antepartum antibiotic prophylaxis. Indeed, as further outlined in this report, GBS intraamniotic infection may dramatically occur before the onset of preterm labor or preterm premature rupture of the membranes.
