Río Vázquez,Vicente; Gil Cruz,Juan José; Téllez Traba,Leonel; Batista Mesa,Bárbara Vivian;
Revista Cubana de Medicina Militar , 2003,
Abstract: the case of a diver that submerged at a depth of 25 meters and on arriving to the surface had occipital intense headache with dizziness and nausea was reported. later, he presented taking of conciousness and neurological focalization. in antero-posterior and lateral radiographies and computerized tomography of the cranium it was observed a large pneumocephalus in the left hemisphere and an osteoma in the left frontal sinus. left frontotemporal craniotomy with evacuation of the pneumocephalus was performed. neurological improvement was observed and 48 hours later he died due to a respiratory infection. the osteoma eroded the posterior wall of the frontal and subdural sinus, which allowed the accumulation of subdural air and prevented its extraction by a mechanism of dural valve.
Neumoencéfalo secundario a barotrauma durante el buceo

Revista Cubana de Medicina Militar , 2003,
Abstract: Se presenta el caso de un buzo que realizó una inmersión a 25 m de profundidad y al llegar a la superficie se le instaló un cuadro de cefalea occipital intensa con mareos y náuseas. Posteriormente presentó toma de la conciencia y focalización neurológica. En radiografía antero-posterior y lateral, tomografía computadorizada de cráneo, se observó un gran neumoencéfalo en hemisferio izquierdo y en osteoma en el seno frontal izquierdo. Se realizó una craneotomía frontotemporal izquierda con evacuación del neumoencéfalo. Posteriormente se observó mejoría neurológica y 48 h más tarde fallece por una infección respiratoria. El osteoma erosionó la pared posterior del seno frontal y subdural, lo que permitió la acumulación de aire subdural y no su salida por un mecanismo de válvula dural.

Observations of two special kinds of tremor at Galeras volcano, Colombia(1989-1991)
F. Gil-Cruz
Annals of Geophysics , 1999, DOI: 10.4401/ag-3727
Abstract: Since the reactivation of Galeras volcano in 1988 its seismic activity has been dominated by a variety of LP waveforms and tremor events. Some of these signals occurred as a response to volcanic activity. Among them, two kinds of tremor deserve special attention, Flute tremor and Spasmodic tremor. Flute tremor has a spectrum of equally spaced peaks and is associated with a quasi-steady degassing process at the top of the lava dome. It is accompanied by a flute-like sound. Its spectral features and the correlation with field observations are consistent with a model generation indicating that a crack or set of cracks are excited to resonance by the release and flow of gas through the lava dome. Spasmodic tremor is composed of several distinct LP-like events joined together by a continuous signal with lower amplitudes. Two types of spasmodic tremor may be distinguished on the basis of their spectral characteristics and field observations. Spasmodic tremor type I is apparently dominated by a mix of P, SH and Rayleigh waves as determined from preliminary polarization analysis. The source appears to be located, in a region west of the active crater. As a first approximation, Spasmodic tremor type I could be associated with magmatic intrusion process occurred in 1989-1991.

Abstract: Our aim is to determine whether computed tomography angiography (CTA) before intravenous thrombolysis (IVT) affects renal function in acute ischemic stroke (AIS) patients. We performed an observational analysis of AIS patients treated with IVT for three years. Patients were classified into 2 groups: those who underwent CTA (CTA-group) and those who did not (control-group). Differences in creatinine levels between baseline and 24–72 hours after IVT were calculated. Acute renal dysfunction (ARD) was defined as an increase in serum creatinine level of ≥0.5?mg/dL and/or ≥25% above baseline within 24–72 hours after IVT. 190 patients were treated with IVT. Renal function (before and after IVT) was assessed in 162 (115 in control-group; 47 in CTA-group). Nine patients (5.5%) developed ARD (2 (4.2%) in CTA-group and 7 (6.1%) in control-group; ). CTA was not associated with a higher risk of ARD and did not affect the efficacy or safety of IVT. Previous chronic renal insufficiency, baseline creatinine levels, and previous use of nonsteroidal anti-inflammatory drugs were associated with a significant increase in creatinine levels, independently of contrast use. In conclusion, CTA does not seem to increase the risk of renal dysfunction. This technique may be used safely without knowledge of baseline creatinine levels. 1. Introduction Computed tomography angiography (CTA) is commonly used in patients with acute ischemic stroke (AIS) to diagnose cerebral arterial occlusion before thrombolysis. This technique makes it possible to identify intracranial and extracranial vascular stenoses or occlusions, which are a relevant prognostic factor indicating intra-arterial interventions such as thrombolysis or mechanical thrombectomy [2–4]. Computed tomography perfusion (CTP) has proven useful for assessing the extent of brain ischemia and for identifying “tissue at risk” that is potentially salvageable with recanalization. CTP also enables clinicians to optimize acute stroke therapy and to predict clinical outcome [5, 6]. The advantages of CTA and CTP over magnetic resonance-based techniques are that they are accessible in the emergency department, inexpensive, fast, and well tolerated. In addition, the spatial resolution of both techniques is high [6]. However, administration of nonionic contrast agents can lead to elevated serum creatinine levels, which are associated with poor outcome and increased mortality in patients with AIS [4, 7, 8], and contrast-induced nephropathy (CIN), which has been associated with higher morbidity and mortality in patients undergoing

Mathematics , 2008, DOI: 10.1063/1.2958181
Abstract: We show an alternative construction of the first example of a simply-connected compact symplectic non-formal 8-manifold given in arXiv:math/0506449. We also give an alternative proof of its non-formality using higher order Massey products.
Symplectic resolutions, Lefschetz property and formality
Gil Cavalcanti,Marisa Fernandez,Vicente Munoz
Mathematics , 2007, DOI: 10.1016/j.aim.2008.01.012
Abstract: We introduce a method to resolve a symplectic orbifold into a smooth symplectic manifold. Then we study how the formality and the Lefschetz property of the symplectic resolution are compared with that of the symplectic orbifold. We also study the formality of the symplectic blow-up of a symplectic orbifold along symplectic submanifolds disjoint from the orbifold singularities. This allows us to construct the first example of a simply connected compact symplectic manifold of dimension 8 which satisfies the Lefschetz property but is not formal, therefore giving a counter-example to a conjecture of Babenko and Taimanov.
