Malignant teratoma in Klippel-Feil syndrome: a case report and review of the literature

Introduction: Klippel-Feil syndrome is characterized by a congenital fusion of cervical vertebrae. Intracranial teratomas are nongerminomatous germ cell tumors and they account for 0.3 to 0.9% of all intracranial tumors. Teratomas with malignant transformation refer to lesions which give rise to malignant cancer of somatic type. The association between tumors of dermoid origin and Klippel-Feil malformation is extremely rare. Only 23 other cases have so far been reported, and only one case of dermoid tumor with areas of dedifferentiation on squamous cell carcinoma has been described. Case presentation: We report the case of a 72-year-old white man with a 2-year history of gait and balance di…

TREAT-TO-TARGET NELLA MIOCARDITE DA M. DI KAWASAKI: DESCRIZIONE DI UN CASO CLINICO

Introduzione La Malattia di Kawasaki (MK) è una vasculite acuta sistemica dei vasi di medio calibro, con interesse elettivo per le arterie coronarie, auto-limitantesi. La diagnosi è clinica, complicanze cardiovascolari quali aneurismi delle coronarie, miocarditi, pericarditi, rappresentano la principale causa di morbilità. Materiali e Metodi R.C, 3.5 anni, giunge per febbre (T max 39°C), letargia, esantema peri-orbitale e alle estremità, iperemia congiuntivale, ritmo di galoppo e disfunzione ventricolare sn ( FE= 50%). Nel sospetto di MK, inizia terapia con IGIV 2gr/kg con scarso beneficio. Viene trasferito presso la TIP per miocardite acuta con insufficienza di pompa, anasarca, acidosi met…

D-0 - (D)over-bar(0) mixing in the standard model and beyond from N-f=2 twisted mass QCD

We present the first unquenched lattice QCD results for the bag parameters controlling the short distance contribution to D meson oscillations in the standard model and beyond. We have used the gauge configurations produced by the European Twisted Mass collaboration with N-f = 2 dynamical quarks, at four lattice spacings and light meson masses in the range 280-500 MeV. Renormalization is carried out nonperturbatively with the regularization-independent momentum subtraction method. The bag-parameter results have been used to constrain new physics effects in D-0 ¿ (D) over bar (0) mixing, to put a lower bound to the generic new physics scale and to constrain off-diagonal squark mass terms for…

Up, down, strange and charm quark masses with N-f=2+1+1 twisted mass lattice QCD

We present a lattice QCD calculation of the up, down, strange and charm quark masses performed using the gauge configurations produced by the European Twisted Mass Collaboration with N-f = 2 + 1 + 1 dynamical quarks, which include in the sea, besides two light mass degenerate quarks, also the strange and charm quarks with masses close to their physical values. The simulations are based on a unitary setup for the two light quarks and on a mixed action approach for the strange and charm quarks. The analysis uses data at three values of the lattice spacing and pion masses in the range 210-450 MeV, allowing for accurate continuum limit and controlled chiral extrapolation. The quark mass renorma…
