Purpose: Silver diamine fluoride (SDF) is an inexpensive, non-invasive, antimicrobial liquid used to treat carious lesions and decrease sensitivity. The purpose of this study was to assess the perceptions of registered dental hygienists in alternative practice (RDHAP) regarding the use of SDF to treat dental caries.Methods: A 16-item survey designed to evaluate RDHAP's familiarity and perceptions of SDF was electronically distributed to 222 RDHAPs practicing in the state of California. A survey research software program collected and tabulated responses, calculated response frequencies for each survey item, and determined statistical relationships among variables, using cross tabulation analysis...

Research into emotional responsiveness in Autism Spectrum Disorder (ASD) has yielded mixed findings. Some studies report uniform, flat and emotionless expressions in ASD; others describe highly variable expressions that are as or even more intense than those of typically developing (TD) individuals. Variability in findings is likely due to differences in study design: some studies have examined posed (i.e., not spontaneous expressions) and others have examined spontaneous expressions in social contexts, during which individuals with ASD-by nature of the disorder-are likely to behave differently than their TD peers...

BACKGROUND: To report a patient with silent sinus syndrome (SSS) who experienced transient ipsilateral monocular vision loss during intense laughter. METHODS: Case report. RESULTS: Our patient's transient vision loss completely resolved after maxillary sinus decompression and during 7 months of follow-up. CONCLUSIONS: Although the precise mechanism of our patient's vision loss remains undetermined, we suspect that the vascular supply to the eye and/or the optic nerve was compromised as the result of the combination of laughter (causing Valsalva maneuver and increased intrathoracic pressure) and SSS...

BACKGROUND: Hypotension is a significant risk factor for the development of ischemic complication following revascularization surgery for moyamoya disease (MMD). However, it is currently unknown whether autonomic dysfunction also plays a role. CASE DESCRIPTION: Here we report a case of MMD in which hypotension due to autonomic dysfunction caused postoperative cerebral ischemia. A 30-year-old female patient with MMD had a history of transient right hemiparesis following laughter...

Humans are intrinsically social animals, forming enduring affiliative bonds [1]. However, a striking minority with psychopathic traits, who present with violent and antisocial behaviors, tend to value other people only insofar as they contribute to their own advancement [2, 3]. Extant research has addressed the neurocognitive processes associated with aggression in such individuals, but we know remarkably little about processes underlying their atypical social affiliation. This is surprising, given the importance of affiliation and bonding in promoting social order and reducing aggression [4, 5]...

REVIEW
Jared Martin, Magdalena Rychlowska, Adrienne Wood, Paula Niedenthal
The human smile is highly variable in both its form and the social contexts in which it is displayed. A social-functional account identifies three distinct smile expressions defined in terms of their effects on the perceiver: reward smiles reinforce desired behavior; affiliation smiles invite and maintain social bonds; and dominance smiles manage hierarchical relationships. Mathematical modeling uncovers the appearance of the smiles, and both human and Bayesian classifiers validate these distinctions. New findings link laughter to reward, affiliation, and dominance, and research suggests that these functions of smiles are recognized across cultures...

Infants laugh by 4 months, but whether they understand humour based on social or cognitive factors is unclear. We conducted two longitudinal studies of 4-, 6-, and 8-month-olds (N = 60), and 5-, 6-, and 7-month-olds (N = 53) to pinpoint the onset of independent humour perception and determine when social and cognitive factors are most salient. Infants were shown six events in randomized repeated-measures designs: two ordinary events and two absurd iterations of those events, with parents' affect manipulated (laugh or neutral) during the latter...

In social interactions, emotionally salient and sudden changes in vocal expressions attract attention. However, only a few studies examined how emotion and attention interact in voice processing. We investigated neutral, happy (laughs) and angry (growls) vocalizations in a modified oddball task. Participants silently counted the targets in each block and rated the valence and arousal of the vocalizations. A combined event-related potential and time-frequency analysis focused on the P3 and pre-stimulus alpha power to capture attention effects in response to unexpected events...

This study examined the development of mother-infant tickling interaction and the relationship between infants' ticklishness and social behaviors including infants' looking at mothers' face, mothers' narrative tickling, and mothers' laughter. Twenty-two Japanese infants aged 5 months (n=10, five girls) and 7 months (n=12, four girls) and their mothers were videotaped. Results revealed that the mothers' narrative tickling was more frequent at 7 than at 5 months and the infants' strong ticklishness showed the same tendency...

Central pontine myelinolysis (CPM) usually occurs with rapid correction of severe chronic hyponatremia. Despite the pronounced fluctuations in serum osmolality, CPM is rarely seen in diabetics. This is a case report of CPM associated with hyperglycemia. A 45-year-old non-smoking and non-alcoholic African American male with past medical history of type 2 diabetes, hypertension, stage V chronic kidney disease and hypothyroidism presented with a two-week history of intermittent episodes of gait imbalance, slurred speech and inappropriate laughter...

Paradoxical kinesia refers to a sudden transient ability of akinetic patients to perform motor tasks they are otherwise unable to perform. The mechanisms underlying this phenomenon are unknown due a paucity of valid animal models that faithfully reproduce paradoxical kinesia. Here, in a first experiment, we present a new method to study paradoxical kinesia by "awakening" cataleptic rats through presenting appetitive 50-kHz ultrasonic vocalizations (USV), which are typical for social situations with positive valence, like juvenile play or sexual encounters ("rat laughter")...

BACKGROUND: Stimulation-induced transient nonmotor psychiatric symptoms (STPSs) are side effects following bilateral subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) patients. We designed algorithms which (1) determine the electrode contacts that induce STPSs and (2) provide a programming protocol to eliminate STPS and maintain the optimal motor functions. Our objective is to test the effectiveness of these algorithms. MATERIALS AND METHODS: 454 PD patients who underwent programming sessions after STN-DBS implantations were retrospectively analyzed...

Various brain areas in both cortical as well as subcortical locations are involved in pathological laughter. Pathological laughter may be seen as a prodromal symptom or acute manifestation or late sequel of stroke. Various other neuropsychiatric conditions attribute to stroke. It is often difficult to ascertain the cause of pathological laughter in the presence of multiple brain pathologies. Here, we highlight a case of a 55-year-old female, who had multiple episodes of stroke and subdural hematoma, presented with pathological laughter and other behavioral abnormalities...

BACKGROUND: Wheezing illnesses are characterized by phenotypic variability, which changes with age, but few studies report on a wide age range of children. We studied how prevalence, severity, and triggers of wheeze vary throughout childhood. METHODS: We analyzed data from a large population-based cohort of children from Leicestershire, UK, who were followed from infancy through late adolescence using postal questionnaires. We used generalized estimating equations to describe age-related changes in prevalence of any wheeze: episodic viral and multiple trigger wheeze; wheeze triggered by exercise, aeroallergens, food/drinks, laughing/crying; and of severe wheeze (frequent attacks, shortness of breath, sleep disturbance, disturbance of daily activities) from age 1-18 years...

OBJECTIVE: To evaluate the effects of a laughter yoga activities (LY) program for older people living in residential aged care homes (RACHs). METHODS: A 6-week LY program was implemented at three RACHs with twenty-eight residents. A pre-post design was used to measure positive and negative affect, happiness, blood pressure and pulse. RESULTS: Post-session mean scores for positive mood, and happiness were significantly higher than pre-session scores in weeks 1, 3 and 6, and the post-session mean negative mood scores were significantly lower than pre-session scores in weeks 3 and 6...

Human emotions, such as anxiety, depression, fear, joy, and laughter, profoundly affect psychological and physiological processes. These emotions form a set of basic, evolved functions that are shared by all humans. Laughter is part of a universal language of basic emotions that all humans recognize. Health care providers and educators may utilize the power of laughter to improve health and enhance teaching and learning. This is an important consideration because teaching is not just about content: it is also about forming relationships and strengthening human connections...

BACKGROUND: Giggle incontinence is a sudden and involuntary episode of urinary incontinence that is provoked by an episode of laughter. Decades of case studies and small research studies have formed the basis of what is known about giggle incontinence; however, much remains unknown about this type of incontinence, leaving the recommendations for clinical management somewhat unguided. METHODS: A systematic review of 22 articles on the topic of "giggle incontinence" and related terms was conducted, including all published articles and commentaries since the term was first seen in print in 1959...
