#1
Alon Kalron
Postural control relies on the integration of inputs from the visual, somatosensory and vestibular systems which are frequently impaired in people with Multiple Sclerosis (PwMS). In this situation, examining the Romberg ratio can be useful. This parameter can be interpreted as a gross indicator of a vestibular and proprioceptive contribution to postural control. Therefore, the primary objective of the current study was to examine whether the Romberg ratio differs between MS fallers, non-fallers and neurological disability levels...

Pantomime-grasps entail a response to an area adjacent to (i.e., spatially dissociated pantomime-grasp), or previously occupied by (i.e., no-target pantomime-grasp) a target. Previous work has reported that pantomime-grasps differ kinematically from naturalistic grasps (i.e., grasping a physical target object) - a result taken to evince that pantomime-grasps are perception-based and mediated via relative visual information. However, such actions differ not only in terms of their visual properties, but also because the former precludes haptic feedback related to a target's absolute size...

Infants learn to use auditory and visual information to organize the sensory world into identifiable objects with particular locations. Here we use a behavioural method to examine infants' use of harmonicity cues to auditory object perception in a multisensory context. Sounds emitted by different objects sum in the air and the auditory system must figure out which parts of the complex waveform belong to different sources (auditory objects). One important cue to this source separation is that complex tones with pitch typically contain a fundamental frequency and harmonics at integer multiples of the fundamental...

Purpose: The purpose of the project was to investigate the effects modifying the secondary task in a dual-task paradigm to measure objective listening effort. To be specific, the complexity and depth of processing were increased relative to a simple secondary task. Method: Three dual-task paradigms were developed for school-age children. The primary task was word recognition. The secondary task was a physical response to a visual probe (simple task), a physical response to a complex probe (increased complexity), or word categorization (increased depth of processing)...

Giant prolactinomas, rare in children, can have devastating endocrine, neurological and visual sequelae. Dopamine agonists (DA) are effective first-line therapy with few side-effects at doses usually used for prolactinoma treatment(1) , but higher-dose therapy for Parkinson's disease has well-recognized associations with impulse control disorders (ICD) including pathological gambling, impulsive eating, compulsive shopping and hypersexuality. Such associations are not well recognized with prolactinomas; to our knowledge this is the first reported case of hypersexuality in an adolescent receiving cabergoline for a giant prolactinoma...

A titratable thermoplastic mandibular advancement device (MAD) is clearly an effective treatment option in some patients with obstructive sleep apnea (OSA). Determining which patients may be more likely to respond to treatment with thermoplastic MADs and to adhere to treatment would be of obvious clinical relevance. This was an experimental descriptive study (N = 60). Patients with OSA were instructed to wear a titratable thermoplastic MAD for 3 months. Treatment success was defined as a ≥50% reduction from baseline in the apnea-hypopnea index (AHI) or AHI <10 when wearing MAD...

A laryngocele is an abnormal dilatation of the laryngeal saccule. It is a rare benign lesion of the larynx. Various modalities of treatment have been advocated for its management. We present our treatment results and outcomes of a series of cases of laryngoceles and discuss the concepts of their management. This study included patients with different laryngocele types. Patients with an internal laryngocele underwent endoscopic CO2 laser resection, while those with a combined laryngocele underwent resection via a V-shaped lateral thyrotomy approach...

Unilateral amblyopia is a visual disorder that arises after selective disruption of visual input to one eye during critical periods of development. In the clinic, amblyopia is understood as poor visual acuity in an eye that was deprived of pattern vision early in life. By its nature, however, amblyopia has an adverse effect on the development of a binocular visual system and the interactions between signals from two eyes. Visual functions aside from visual acuity are impacted, and many studies have indicated compromised sensitivity in the fellow eye even though it demonstrates normal visual acuity...

The way in which light is polarized when reflected from leaves can be affected by infection with plant viruses. This has the potential to influence viral transmission by insect vectors due to altered visual attractiveness of infected plants. The optical and topological properties of cuticular waxes and trichomes are important determinants of how light is polarized upon reflection. Changes in expression of genes involved in the formation of surface structures have also been reported following viral infection...

Body Mass Index has traditionally been used as a measure of health, but Fat Mass Index (FMI) and Lean Mass Index (LMI) have been shown to be more predictive of mortality and health risk. Total body FMI and LMI reference curves have particularly been useful in quantifying sarcopenia and sarcopenic obesity. Research has shown regional composition has significant associations to health outcomes. We derived FMI and LMI reference curves of the regions of the body (leg, arm, and trunk) for 15,908 individuals in the 1999-2004 National Health and Nutrition Examination Survey data for each sex and ethnicity using the Lambda-Mu-Sigma (LMS) method and developed software to visualize this regional composition...

Hydroxycarbamide, available as tablets, is a pharmacological agent for fetal hemoglobin induction such as sickle cell anemia. The need for alternative dosage form options for patients unable to take tablets led hospital pharmacies to prepare solutions and suspensions. The objective of this study was to determine the stability of hydroxycarbamide in Ora-Plus in combination with either Ora-Sweet or Ora-Sweet SF, Ora-Blend, or Ora-Blend SF suspending agents. The studied samples were compounded into 100-mg/mL suspensions and stored in 60-mL amber glass bottles at room (22°C to 25°C) or refrigerated (4°C to 8°C) temperature...

Dehydroepiandrosterone supplementation is used to treat a variety of conditions. Rapid-dissolving tablets are a relatively novel choice for compounded dehydroepiandrosterone dosage forms. While rapid-dissolving tablets offer ease of administration, there are uncertainties about the physical and chemical stability of the drug and dosage form during preparation and over long-term storage. This study was designed to evaluate the stability of dehydroepiandrosterone rapid-dissolving tablets just after preparation and over six months of storage...
