Infecciones orofaciales de origen odontogénico
La naturaleza polimicrobiana de las infecciones odontógenas
así como la heterogeneidad de los cuadros clínicos asociados
son consecuencia de la diversidad de la microbiota bucal y de
la complejidad anatómica y funcional de la cavidad oral. Así
mismo, estos procesos pueden dar lugar a múltiples complicaciones
que pueden limitarse a afecciones locales o derivar hasta
compromisos sistémicos.
En el tratamiento farmacológico de estas infecciones es crucial
la elección del antibiótico y la pauta posológica más eficaces.
La farmacodinamia proporciona los parámetros que hacen posible
valorar como varía la actividad de los antibióticos en función
del tiempo.
Como norma general, en el manejo inicial de las infecciones
orofaciales en el adulto, incluidas las infecciones odontógenas,
se utilizará amoxicilina/ac. Clavulánico en dosis de 875 mg de
amoxicilina y 125 mg de ac. clavulánico pautado cada 8 horas.
El cumplimiento terapéutico es clave para evitar la aparición
de resistencias, por lo que se ha de maximizar la aceptación por
parte de los pacientes. En este sentido se ha demostrado que la
nueva presentación de 2000/125 mg de Augmentine Plus pautado
cada 12 horas tanto en profilaxis como tratamiento disminuye
significativamente la tasa de complicaciones infecciosas
derivada de la extracción del tercer molar.The polymicrobial nature of the odontogenic infections as well
as the variety of associated conditions are a consequence of the
diversity of the buccal microbiota and the anatomical and
functional complexity of the oral cavity. In addition to this, all
these processes can give way to multiple complications which
range from the local to the systemic level.
The appropriate choice of antibiotic and posology is crucial in
the successful management of these infections. Pharmacodynamics
provides those parameters that make it possible to assess
how antibiotics activity varies in time. As a general rule, the
first step in the initial management of orofacial infections in
adults, included odontogenic infections, will be the
administration of 875 mg of amoxicillin and 125 mg of
clavulanic every 8 hours. Therapeutic compliance is paramount to avoid resistance,
therefore patient's acceptance must be sought. In this sense, it
has been proved that Augmentine Plus (2000/125) every twelve
hours both as profylaxis and as treatment significantly decreases
the rate of infective complications associated to extraction of
the third molar
A Practical Environment to Apply Model-Driven Web Engineering
The application of a model-driven paradigm in the development of Web Systems has yielded very good research
results. Several research groups are defining metamodels, transformations, and tools which offer a suitable environment,
known as model-driven Web engineering (MDWE). However, there are very few practical experiences in real
Web system developments using real development teams. This chapter presents a practical environment of MDWE
based on the use of NDT (navigational development techniques) and Java Web systems, and it provides a practical
evaluation of its application within a real project: specialized Diraya.Ministerio de Educación y Ciencia TIN2007-67843-C06-03Ministerio de Educación y Ciencia TIN2007-30391-
Towards a Programming Language in Cellular Computing
AbstractSeveral solutions to hard numerical problems using P systems have been presented recently, and strong similarities in their designs have been noticed. In this paper we present a new solution, to the Partition problem, via a family of deterministic P systems with active membranes using 2-division. Then, we intend to show that the idea of a cellular programming language is possible (at least for some relevant family of NP-complete problems), indicating some “subroutines” that can be used in a variety of situations and therefore could be useful for designing solutions for new problems in the future
Bounds on the anomalous vertex arising from the process
We obtain limits on the anomalous coupling through data published
by the L3 Collaboration on the process . Our
analysis leads to bounds on this coupling of order , for an
intermediate mass Higgs boson , two orders of magnitude
above the Standard Model prediction.Comment: 10 pages, 3 figure
Y-stent-assisted coil embolization of anterior circulation aneurysms using two solitaire AB devices: a single enter experience
Wide-neck intracranial aneurysms remain a
challenge to endovascular treatment. We describe
our experience in repairing wide-neck
aneurysms of the anterior circulation located at
arterial branch points using coil embolization
assisted by Y-stenting using two Solitaire® stents.
Six wide-neck intracranial aneurysms located
on the middle cerebral artery bifurcation 3, pericallosal
artery 1, and anterior communicating
artery 2 were repaired by Y-stent-assisted coil
embolization using two Solitaire® stents. Four
cases were incidental findings of aneurysm and
two cases were previously treated ruptured aneurysms
that had undergone recanalization.
All the cases were successfully treated without
complications. Follow-up by digital subtraction
angiography and magnetic resonance angiography
at six months showed the stents to be patent
with no recanalization of the aneurysm sacs.
Repairing wide-neck aneurysms of the anterior
circulation by Y-stent-assisted coil embolization
using two Solitaire® stents is a simple
and safe method of treating complex aneurysms.
While the results are promising, larger
series with longer term follow-ups are needed to
corroborate that this treatment method is superior
to other technique
Limits on the Electromagnetic and Weak Dipole Moments of the Tau-Lepton in E_6 Superstring Models
We obtain limits on the electromagnetic and weak dipole moments of the
tau-lepton in the framework of a Left-Right symmetric model (LRSM) and a class
of inspired models with an additional neutral vector boson .
Using as an input the data obtained by the L3 and OPAL Collaborations for the
reaction , we get a stringent limit on the LRSM
mixing angle , , which in
turn induces bounds on the tau weak dipole moments which are consistent with
the bounds obtained recently by the DELPHI and ALEPH Collaborations from the
reaction . We also get similar bounds for the weak
dipole moments of the tau lepton in the framework of superstring models.Comment: 18 pages, 5 figure
On the uniformization of L-valued frames
This note discusses the appropriate way of uniformizing the notion
of an L-valued frame introduced by A. Pultr and S. Rodabaugh in [Lattice-valued
frames, functor categories, and classes of sober spaces, Chapter 6 of Topological
and Algebraic Structures in Fuzzy Sets: A Handbook of Recent Developments in
the Mathematics of Fuzzy Sets, Kluwer, 2003]. It covers the case of a completely
distributive lattice L (which is, in a certain sense, the most general one) and studies
the corresponding category of uniform L-valued frames
Evaluation and optimization of the Sysmex UF1000i system for the screening of urinary tract infection in primary health care elderly patients
Objective Urinary tract infections (UTIs) are a common problem in the elderly population. Urine culture is still considered the "gold standard" to diagnose infection in this population. However, urine cultures are laborious and costly, and most samples will yield no growth. Methods An evaluation was made of the Sysmex UF-1000i flow cytometer as a screening tool for UTI in an elderly population older than 65 years who lived in the community, using 346 urine samples submitted for culture. Results The Receiver Operating Characteristic (ROC) analysis showed a significant difference (P < 0.01) between 0.98 bacteria area under the curve value and 0.82 of white blood cells (WBC). The combination of both counts for screening did not show any improvement in specificity or sensitivity. According to our data, the use of a single cut-off point of 200 bacteria/μL is suggested, in which the sensitivity and specificity were 99.11% and 91.59%, respectively, with a NPV of 99.49%. Moreover, this cut-off value could avoid 60.24% of the samples to be cultured, with a minimal false negative results rate of 0.87%. Conclusions The stratification of age groups stratification helps in selecting a more adjusted Sysmex UF1000i cut-off limit, leading to an improvement in the screening parameters that would imply a better management of these infections, as well as a high reduction in the workload and cost savings
Electronic structure of crystalline binary and ternary Cd-Te-O compounds
The electronic structure of crystalline CdTe, CdO, -TeO,
CdTeO and CdTeO is studied by means of first principles
calculations. The band structure, total and partial density of states, and
charge densities are presented. For -TeO and CdTeO, Density
Functional Theory within the Local Density Approximation (LDA) correctly
describes the insulating character of these compounds. In the first four
compounds, LDA underestimates the optical bandgap by roughly 1 eV. Based on
this trend, we predict an optical bandgap of 1.7 eV for CdTeO. This
material shows an isolated conduction band with a low effective mass, thus
explaining its semiconducting character observed recently. In all these oxides,
the top valence bands are formed mainly from the O 2p electrons. On the other
hand, the binding energy of the Cd 4d band, relative to the valence band
maximum, in the ternary compounds is smaller than in CdTe and CdO.Comment: 13 pages, 15 figures, 2 tables. Accepted in Phys Rev
