    The Neonate with Minor Dysmorphisms

    Congenital anomalies are present in at least 10% of all neonatal intensive care unit admissions, of whom many have an underlying genetic condition. About 50–60% of human congenital anomalies are of unknown etiology, and approximately one- third are caused by genetic factors. A smaller percentage of birth defects are the result of chromosomal aberrations and gene mutations. Around 1 in 40 or 2.5% of all newborns have a malformation at birth. This may be an isolated malformation or may occur together with other malformations and/or dysmorphic features as part of a malformation syndrome. Around 4000 malformation syndromes have now been delineated. Many are associated with medical problems and making a specific syndrome diagnosis can influence immediate medical management. However, the infant with dysmorphism often does not have a major malformation, and may simply have an appearance that is unusual compared with the general population and of unaffected close relatives. The chapter intends to provide semnificative data concerning the approach and management of a dysmorphic neonate, mainly when there are minor anomalies and will offer all those relevant data and try to establish a protocol guide for the approach of the dimorphic neonate

    Pregnancy in the context of Multiple Sclerosis

    Get PDF
    Multiple Sclerosis is a chronic autoimmune neurodegenerative disorder which affects brain, spinal cord and optic nerve. During last years the perception over the disease changed dramatically, now being considered a handleable disease. The particularity of this subject is that Multiple Sclerosis is a disease which affects mostly young women, many of them not having any children at the moment of diagnosis. This article highlights the fact that women diagnosed with Multiple Sclerosis are allowed to get pregnant, and, moreover, they are encouraged to live a normal life. In most cases, disease activity freezes during pregnancy, only a small percentage of women will continue to have clinically and radiologically active disease. For those women, IFN-β and Glatiramer Acetate are the first-choice therapies that should be given. In cases when the disease is not responding to common medication, refractory to treatment forms may be successfully treated with Natalizuab, during the first and the second trimester. Breastfeeding is also encouraged, as it has a protective effect on disease progression. The main purpose of this article is to make a literature review in which to summarize the updates regarding pregnancy and postpartum management, relapses management and, also, the impact of pregnancy on Multiple Sclerosis course. The analysis was limited to articles written in English and published between August 2019 - October 2022 on PubMed, NCBI and Medical Journals

    Oligohydramnios: A review of etiology and management options

    Get PDF
    Oligohydramnios is both a consequence of fetal malformations and of uteroplacental insufficiency. Its existence is associated with a high rate of both antepartum and intrapartum complications. It is vital that its occurrence is detected as early as possible so that we can manage it correctly. The main causes of its occurrence are identified and described in this review. The management of oligohydramnios is most often expectant, the timing of delivery also being determined by Doppler examination and changes in parameters measuring fetal growth and development

    Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

    Get PDF
    We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

    Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

    Get PDF
    The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.

    Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

    Get PDF
    The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.
