Carlos Yanez, Sandra Velázquez, Nallely Mora
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.41002
Abstract: Objective: To review the long term outcomes of cross-hatching Eustachian Tuboplasty (ChEt) in patients with chronic obstructive Eustachian tube dysfunction (COETD), as well as assess the clinical factors associated with surgical success. Study Design: Retrospective case series review. Setting: Tertiary healthcare institution. Methods: This is a retrospective review of non-revision ChET for COETD. Follow-up period was 5 years. The inclusion criteria were persistent otitis media with effusion, conductive hearing loss of 5 or more years, and constant COETD related-symptoms. The curvature of the posterior cushion was modified using an argon laser to alter the spring of the cartilage alleviating the obstructed valve’s aperture. Several clinical factors were reviewed in relation to the successful opening of Eustachian tube valve. Results: One hundred and twenty patients, 72 males/48 females, average age 42.4 + 2 years old, met study inclusion criteria. COETD patients/ obstructive causes were: Posterior cushion hypertrophy, 68 (56.6%); Tensor Veli and Levator Veli Palatini muscles hypertrophy, 15 (12.5%); Remarkable mucosal hypertrophic disease, 37 (30.8%). Total of ET tubes was 198. Bilateral 143 (72.2%), 55 unilateral (27.7%) ET valve was seen more open postoperatively on simple endoscopy (SE) and slow motion video analysis (SMVEA). There were no complications. Mean pure tone average improved by 20 dB postoperatively; P = 0.015. Mean immitance changes in tympanometric measurements improved postoperatively at least 0.10 mmhos in 91% of the patients (P = 0.010). Resolution of symptoms was considered a successful outcome. Failure correlated with the severity of disease. Conclusion: High rates of improvement (96%) were achieved. ChEt is a promising technique for the treatment of COETD
Electroencephalographic Abnormalities in Patients with Idiopathic Insomnia  [PDF]
Debora Yoaly Arana Lechuga, Oscar Sánchez Escandón, Miguel Collado Corona, Carlos Castillo Montoya, González Robles R., Anabel Jiménez Anguiano, Oscar Prospero García, Javier Velázquez Moctezuma
Neuroscience & Medicine (NM) , 2011, DOI: 10.4236/nm.2011.23024
Abstract: Objective: The main goal of the present research is to describe the electroencephalographic activity during sleep and the cyclic alternating pattern (CAP) on idiopathic insomniac patients. Methods: 22 idiopathic insomnia patients were included. Sleep recording included: fully conventional EEG recording (32 electrodes, with 16 channels getting ipsilateral bipolar recordings), EOG, EMG, EKG, thoracic and abdominal respiratory movements, nasal flow and oximetry. Results: Out of the 22 registered patients, 10 (45%) showed no electroencephalographic alteration, while 12 (55%) exhibited an electroencephalographic alteration (irritative activity). Concerning PSG variables, significant differences between groups (no EEG alteration and EEG alterations) were detected in: sleep latency, total sleep time, total wake time, sleep efficiency, light sleep percentage, slow waves sleep percentage and on the sub type A1 index of the cyclic alternant pattern CAP. Conclusions: The present data strongly suggest that within the population diagnosed with idiopathic insomnia, there is a subgroup in which the electroencephalographic alterations may play a critical role as the source of the sleep abnormality.
Analysis of the Effects of the Implementation of Cooperative Learning in Physical Education
Carlos Velázquez Callado
Qualitative Research in Education , 2012, DOI: 10.4471/qre.2012.04
Abstract: Our research was oriented to test the effects of a structured program of cooperative learning in Physical Education classes with students in grades 5 and 6 of primary school, with and without previous experience with this methodology. In a second phase we sought to determine how students perceived the received classes for a time later.We analysed data collected during implementation, through cooperative learning, of two teaching units to a total of six groups of students; in addition, a number of interviews, five individual and one collective, were carried out to a total of 10 former students who had left school between one and five years earlier.The results show the positive effects of cooperative learning on students' motor performance, and some social achievements such as a greater autonomy of the students in the learning process, an increasing in prosocial behaviours and the inclusion of pupils with special educational needs. On the other hand, as time went on, the students rated the received classes as cooperative, participatory, funny and useful, emphasizing peer support as a key factor that enabled them to learn in Physical Education.
About One-Dimensional Conservative Systems with Position Depending Mass  [PDF]
Gustavo López Velázquez, Carlos Rodrigo Martínez Prieto
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.59093
Abstract:

For a one-dimensional conservative system with position depending mass, one deduces consistently a constant of motion, a Lagrangian, and a Hamiltonian for the nonrelativistic case. With these functions, one shows the trajectories on the spaces (x,v) and (x,p) for a linear position depending mass. For the relativistic case, the Lagrangian and Hamiltonian cannot be given explicitly in general. However, we study the particular system with constant force and mass linear dependence on the position where the Lagrangian can be found explicitly, but the Hamiltonian remains implicit in the constant of motion.

Revista Cubana de Pediatr?-a , 1998,
Abstract: Se hace una revisión de los principales elementos implicados en la respuesta inflamatoria del individuo a la infección, por el beneficio que este conocimiento reporta al mejor manejo terapéutico de los pacientes. Se revisan los principales protagonistas de la inflamación, desde los detonantes como: lipopolisacárido, peptidoglicano, ácidos lipoteicoico y murámico, hasta los principales mediadores implicados. Se discute el proceso de activación de monocitos y células endoteliales y la repercusión de ello, y se hace un análisis dinámico del proceso de activación en función del tiempo trancurrido desde el comienzo de la infección, y sus etapas fisiopatológicas. Se evidencia el papel protagónico que tiene el propio organismo en el da o producido por la respuesta a la infección, además de la importancia del adecuado equilibrio entre proinflamación y contrarregulación para el pronóstico del enfermo, lo que obliga a tenerlo en cuenta a la hora del tratamiento.
