Botulinum toxin for the treatment of somatic tinnitus
2007
Subjective tinnitus is an auditory sensation experienced in the absence of external or internal acoustic stimuli. It causes significant morbidity and can progress to a chronic debilitating condition. Somatic tinnitus is tinnitus that can be modulated by stimulation of the somatic sensory system. It occurs because of interactions between the auditory and the somatosensory system that may occur at several levels of the central nervous system. In the present chapter, we discuss how botulinum toxin can improve tinnitus and discuss the mechanism of its action, and how it relates to its effects on chronic pain.
Wearable Sensor for Assessing Gait and Postural Alterations in Patients with Diabetes: A Scoping Review.
2021
Background and Objectives: Diabetes mellitus is considered a serious public health problem due to its high prevalence and related complications, including gait and posture impairments due to neuropathy and vascular alterations and the subsequent increased risk of falls. The gait of patients with diabetes is characterized by alterations of the main spatiotemporal gait parameters such as gait velocity, cadence, stride time and length, which are also known to worsen with disease course. Wearable sensor systems can be used for gait analysis by providing spatiotemporal parameters and postural control (evaluated from the perspective of body sway), useful for investigating the disease progression.…
Documento de consenso sobre asma y tabaquismo del Foro Autonómico de Asma de la SEPAR
2021
La prevalencia de tabaquismo activo en adultos con asma es similar a la de la población general. El tabaquismo se asocia con un peor control clínico de la enfermedad, una disminución acelerada de la función pulmonar y una respuesta irregular a la terapia con glucocorticoides. El consumo de tabaco impacta negativamente en la calidad de vida de los pacientes asmáticos y provoca un incremento en el número de visitas y de hospitalizaciones por exacerbaciones. Además, el tabaquismo aumenta el riesgo de cáncer de pulmón, comorbilidades cardiovasculares y muerte en pacientes asmáticos. A pesar de todo ello, las guías actuales del manejo del asma no incluyen recomendaciones específicas para el mane…

Deviance detection in sound frequency in simple and complex sounds in urethane-anesthetized rats
2019
Mismatch negativity (MMN), which is an electrophysiological response demonstrated in humans and animals, reflects memory-based deviance detection in a series of sounds. However, only a few studies on rodents have used control conditions that were sufficient in eliminating confounding factors that could also explain differential responses to deviant sounds. Furthermore, it is unclear if change detection occurs similarly for sinusoidal and complex sounds. In this study, we investigated frequency change detection in urethane-anesthetized rats by recording local-field potentials from the dura above the auditory cortex. We studied change detection in sinusoidal and complex sounds in a series of …

Evaluation of movement and brain activity
2021
Clinical neurophysiology studies can contribute important information about the physiology of human movement and the pathophysiology and diagnosis of different movement disorders. Some techniques can be accomplished in a routine clinical neurophysiology laboratory and others require some special equipment. This review, initiating a series of articles on this topic, focuses on the methods and techniques. The methods reviewed include EMG, EEG, MEG, evoked potentials, coherence, accelerometry, coherence, posturography (balance), gait, and sleep studies. Functional MRI (fMRI) is also reviewed as a physiological method that can be used independently or together with other methods. A few applicat…

This study investigated the role of vection (i.e., a visually induced sense of self-motion), optokinetic nystagmus (OKN), and inadvertent head movements in visually induced motion sickness (VIMS), evoked by yaw rotation of the visual surround. These three elements have all been proposed as contributing factors in VIMS, as they can be linked to different motion sickness theories. However, a full understanding of the role of each factor is still lacking because independent manipulation has proven difficult in the past. We adopted an integrative approach to the problem by obtaining measures of potentially relevant parameters in four experimental conditions and subsequently combining them in a …

Little is known about somatosensory evoked potentials (SEPs) from muscle stimulation compared to that from skin stimulation. The current study examined this issue in the full SEP spectrum (0 - 440 ms). The aims of the study were to (1) establish the dynamics of early to late latency SEPs from intramuscular stimulation in contrast to surface stimulation, (2) compare the effect of non-painful and painful stimuli on SEP latencies and amplitudes of the two methods, and (3) investigate to which extent these results can be shared between the median nerve innervated thenar site and ulnar nerve innervated hypothenar site. Stimuli were delivered (2 Hz) at a non-painful and a painful intensity above …
