Distraction With Virtual Reality Goggles in Paediatric Dental Treatment: A Randomised Controlled Trial.

AIM: The aim of this study was to examine whether screening content through virtual reality (VR) goggles can diminish pain perception during local anaesthesia administered using the inferior alveolar nerve block technique and rubber dam placement in routine paediatric dental treatment. MATERIALS AND METHODS: This is a crossover study of healthy 4- to 12-year-old children who were scheduled to receive local anaesthesia administered using the inferior alveolar nerve block technique and rubber dam placement in 2 visits. The participants were randomly assigned to undergo 1 treatment performed with Oculus GO VR goggles and the other treatment without. Pain was evaluated using the Wong-Baker FACES Pain Rating Scale and the Modified Behavioral Pain Scale (MBPS). RESULTS: The study group included 29 children with a mean age of 8.29 years (SD, 1.96). Whilst administering local anaesthesia, no significant difference was observed in the Wong-Baker FACES Pain Rating Scale and in MBPS movements between visits with and without the VR goggles. However, significantly lower pain perception was observed in the other parameters of MBPS when using the VR goggles: Face (P = .007) and Cry (P = .046). During placement of a rubber dam, significantly less pain was reported by the patients (P = .005) and observed by the assessor (Face [P = .005], Cry [P = .029], and Movement [P = 0.028]) when the VR goggles were used. CONCLUSIONS: VR can decrease pain perception during rubber dam placement in children, but it has limited benefit during administration of local anaesthesia.

Blue-blocking glasses as additive treatment for mania: Effects on actigraphy-derived sleep parameters.

Improvement of sleep is a central treatment goal for patients in a manic state. Blue-blocking (BB) glasses as adjunctive treatment hasten overall recovery from mania. This method is an evolvement from dark therapy and builds on the discovery of the blue-light-sensitive retinal ganglion cell that signals daytime to the brain. We report effects of adjunctive BB glasses on actigraphy-derived sleep parameters for manic inpatients as compared to placebo. Hospitalized patients with bipolar disorder in a manic state aged 18-70 years were recruited from five clinics in Norway from February 2012 to February 2015. The participants were randomly allocated to wearing BB glasses or placebo (clear glasses) as an adjunctive treatment from 18:00 to 08:00 hours for seven consecutive nights. Sleep and wake were monitored by actigraphy. From 32 eligible patients, 10 patients in each group qualified for the group analyses. The BB group's mean sleep efficiency was significantly higher at night 5 as compared to the placebo group (92.6% vs. 83.1%, p = .027). The 95% confidence interval (CI) was 89.4%-95.8% in the BB group and 75.9%-90.3% in the placebo group. There were fewer nights of interrupted sleep in the BB group: 29.6% versus 43.8% in the placebo group. The BB group received less-intensive sleep-promoting pharmacological treatment and showed significantly higher sleep efficiency and more consolidated sleep as compared to the placebo group. Our findings suggest sleep-promoting effects through deactivating mechanisms. Adjunctive BB glasses seem to be useful for improving sleep for manic patients in the hospital setting.

An investigation of different types of eyewear and face shields in protecting patients and operators from the harmful effects of ultraviolet radiation.

BACKGROUND: Phototherapy and photochemotherapy are commonly used treatment modalities for a range of chronic skin conditions. Whilst undergoing ultraviolet radiation exposure, patients can wear personal protective equipment. Face shields in combination with other forms of skin cover may be worn to provide both skin and eye protection. There are a number of different types of eyewear and face shields available for purchase. Some of these have clear identifications that show the levels of protection provided whilst others may not have any. METHODS: A series of similar experiments has been undertaken independently at two phototherapy treatment centres-Chapel Allerton Hospital, Leeds and Ninewells Hospital, Dundee-to investigate the effectiveness of different face shields and eye protection that are available for purchase in the United Kingdom (UK). Two similar examples of one face shield were tested at both centres, and another was transferred between the units. RESULTS: Not all examples of the face shields and protective eyewear provided the wearer full protection between 300 nanometres and 400 nanometres (nm). Cost and conformance to different standards was not always a good indicator. Some inexpensive examples tested also met British Association of Dermatology protective sunglasses guidelines. CONCLUSIONS: It is incumbent on all centres to check the properties of protective face shields and eyewear provided to patients and operators to guard against the effects from ultraviolet radiation. There is no correlation between price of the protective equipment and level of protection offered, and there may be opportunity for cost savings.

Measurement and Nonpharmacologic Management of Sleep Disturbance in the Intensive Care Units: A Literature Review.

The general goal of this review is to summarize, clarify, and evaluate what is known about patients' sleep in the intensive care units (ICUs) in terms of sleep measurement and management. In addition, this review focuses on the gap in knowledge in this field. A review of online databases for relevant articles in the period between 2000 and 2017 was conducted. The results of this study indicate that there are several methods to measure patients' quality of sleep. Polysomnography and actigraphy are the most common standard objective and valid methods used to measure sleep disorders in the ICU. On the contrary, several subjective instruments are used such as the Richards-Campbell Sleep Scale, Verran Snyder Harper Sleep Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Sleep Efficiency Index. To improve patients' sleep in the ICU, various strategies are used internationally. These strategies include reducing the noise and light levels; using relaxation technique, meditation, hypnosis, earplugs, eye masks, relaxation music; and modifying the time of delivering nursing care.

Glaucoma pathogenesis and lifestyle modification

Glaucoma is the leading cause of irreversible blindness worldwide. Increased intraocular pressure is the most important risk factor for glaucoma. Lifestyle patterns that can increase intraocular pressure include smoking, caffeine consumption, lifting heavy weights, certain yoga postures, playing wind instruments, using swimming goggles, and certain sleeping positions. Lifestyle patterns that may reduce intraocular pressure include aerobic exercise. Although only limited studies have investigated the relationship between these lifestyle patterns and glaucoma, smoking cessation and aerobic exercise are recommended. For other lifestyle patterns, including caffeine consumption, lifting heavy weights, certain yoga postures, wind instruments, swimming using goggles, and certain sleeping positions, there does not seem to be sufficient evidence to prohibit them, but they should be taken into account in patients with advanced glaucoma.

Safety of neonatal phototherapy lamp exposure.

A routine review of light exposure within a neonatal intensive care unit is described following the introduction of a new model of neonatal phototherapy lamp. Spectral measurements were undertaken using a Bentham Dmc150 spectroradiometer system. Safety assessments were undertaken based on likely exposure of parents at the cot side, neonates in adjacent cots and the effectiveness of eye protection for neonates with direct phototherapy. An aphakic eye response was used for assessment of neonatal risk and the blue-light response for estimation of adult exposure using current ICNIRP guidelines. Such estimations indicated exposure levels of parents at the cot side and neonates in adjacent cots were within current established safe limits. The level of light blocking provided by the available neonatal eye protection was estimated to be entirely adequate and presented no hazard to the infant when correctly positioned over the neonate. It is likely, however, that an increased safety factor is potentially present for the neonate due to the fact that the neonate's eyes will typically be shut for over 50% of the time. It is identified, however, that the aphakic response is essentially associated with mature adult retinal cells, and that the maturing cells of the neonate may exhibit additional light sensitivity, especially in the case of premature infants. Changes in neonatal physiology associated with neonatal phototherapy are discussed, which may influence mechanisms of light-induced retinal damage.

Phototherapy-related ophthalmologic disorders.

Phototherapy is an effective treatment option for a variety of dermatologic disorders, and the list of indications for its use continues to grow with advances in technology and our understanding of disease processes. Commonly used types of phototherapy include PUVA, broadband UVB, narrowband UVB, photodynamic therapy, and intense pulsed light therapy. Each therapeutic modality can have adverse acute and chronic effects on periocular and ocular structures, including the conjunctiva, cornea, crystalline lens, and retina. There are many types of protective eyewear options available, including goggles and contact lenses that can be used to prevent damage to ocular structures during phototherapy, particularly if eyelid closure is incomplete.

Evaluation of a novel eyelid-warming device in meibomian gland dysfunction unresponsive to traditional warm compress treatment: an in vivo confocal study.

The purpose of the study was to evaluate the efficacy and safety of wet chamber warming goggles (Blephasteam(®)) in patients with meibomian gland dysfunction (MGD) unresponsive to warm compress treatment. We consecutively enrolled 50 adult patients with low-delivery, non-cicatricial, MGD, and we instructed them to apply warm compresses twice a day for 10 min for 3 weeks and to use Blephasteam(®) (Laboratoires Thea, Clermont-Ferrand, France) twice a day for 10 min for the following 3 weeks. We considered "not-responders" to warm compress treatment the patients who showed no clinically significant Ocular Surface Disease Index (OSDI) improvement after the first 3 weeks. Clinical and in vivo confocal outcome measures were assessed in the worst eye (lower BUT) at baseline, after 3 weeks, and after 6 weeks. Eighteen/50 patients were not-responders to warm compress treatment. These patients, after 3 weeks of treatment with Blephasteam(®), showed significant improvement of OSDI score (36.4 ± 15.8 vs 20.2 ± 12.4; P < 0.05, paired samples t test), increased BUT (3.4 ± 1.6 vs 7.6 ± 2.7; P < 0.05), and decreased acinar diameter and area (98.4 ± 18.6 vs 64.5 ± 14.4 and 8,037 ± 1,411 vs 5,532 ± 1,172, respectively; P < 0.05). Neither warm compresses nor Blephasteam(®) determined adverse responses. In conclusion, eyelid warming is the mainstay of the clinical treatment of MGD and its poor results may be often due to lack of compliance and standardization. Blephasteam(®) wet chamber warming goggles are a promising alternative to classical warm compress treatment, potentially able to improve the effectiveness of the "warming approach."

Evaluation of an eyelid warming device (Blephasteam) for the management of ocular surface diseases in France: the ESPOIR study.

INTRODUCTION: Eyelid hygiene, including massage and warm compresses, is an important part of the treatment and prevention of Meibomian gland dysfunction (MGD). Although effective, it requires active participation of the patient and lacks standardisation. Blephasteam is a medical device designed to warm and humidify the eyelid with heating glasses, in order to liquify meibum, thus relieving symptoms and preventing relapse. MATERIALS AND METHODS: The ESPOIR study (Evaluation of the Satisfaction of Patients with Management of Ocular Surface Diseases) presented herein was designed to evaluate the safety and efficacy of this medical device in patients with MGD. A total of 28 French centers participated in the study. One hundred and two patients presenting with symptomatic dysfunction or Meibomian-related dry eye underwent two sessions per day with the eyelid warming device and recorded diary entries on a number of parameters every 2 days for the first week and then weekly for the remaining 2 weeks. Patients were assessed on days 0 and 21. RESULTS: Symptomatology, as recorded on a visual analogue scale (VAS) by the investigator (the primary efficacy variable) was significantly (P<0.001) improved at the end of the study (59.97, 95% CI 55.64-64.30 vs. 39.71, 95% CI 34.78-44.65 on Days 0 and 21 respectively), as was the mean symptoms score (mean decrease of 19.93 ± 22.15 VAS units; P<0.001), hyperemia score (-1.57 ± 1.96 and -1.45 ± 1.85; P<0.001, in the worse and contralateral eye respectively), and quality of meibum (mean -4.03 ± 3.08; P<0.001 and -3.32 ± 3.20; P<0.01, in the worse and contralateral eye respectively). More than twice as many reported their symptoms had improved or disappeared compared with those whose symptoms had not changed or had worsened. Global symptomatology, as assessed by the patients, declined throughout the study, and a large majority of patients were satisfied or very satisfied with the treatment. Clear vision and blinking were not impaired during use of the eyelid warming device, which insures proper spreading of the tear film, and patients were able to continue daily activities such as reading and watching television. No adverse events were reported, and there were no changes in intraocular pressure or visual acuity. Safety was rated as satisfactory or very satisfactory by more than 95% of the investigators. CONCLUSION: The study suggests that the eyelid warming device is safe and effective in reducing ocular discomfort and symptoms in MGD.

Protective efficacy of sunglasses on the conjunctival symptoms of seasonal rhinitis.

BACKGROUND: Although allergen avoidance can lead to significant improvements in symptoms of allergic rhinitis, there are very few studies in this area. Sunglasses could be effective for protection of eyes from pollen as a cheap, comfortable, and simple avoidance option for allergens. The aim of this study is to determine if wearing sunglasses can decrease ocular symptoms. METHODS: Ocular symptomatic patients (39 total) who had a confirmed history of seasonal rhinitis by skin prick tests and negative skin prick tests for perennial allergens were included in the study. The duration of the study was 4 weeks with 3 required visits. At the onset of the 1-week run-in period, patients were randomized and divided into 2 groups. Group I (n = 18) received topical aqueous nasal budesonide regularly and loratadine once daily as a rescue medication. Group II (n = 21) wore sunglasses during daytime as an addition to this medication. Subjective data included a daily diary recording nasal and ocular symptom scores and antihistamine need during the study period. RESULTS: Sunglasses significantly reduced ocular symptoms (p = 0.002) and use of antihistamines (p = 0.009). CONCLUSION: Sunglasses are an inexpensive and simple treatment for patients with allergic conjunctivitis.

The effect of night vision goggles on the retinocortical bioelectrical activity and its improvement by food supplement.

AIM: To investigate the effect of luminance variations, as well as the oral administration of a food supplement, on the visual bioelectric response while using of Night Vision Goggles (NVG). METHODS: Two trials were performed, both enrolling healthy male aircrew members wearing NVG, and recording Visual Evoked Potentials (VEPs) from scalp electrodes. Both foveal and parafoveal response were evaluated. Latency and amplitude, P100 peak, were measured. In the first set of measurements, VEPs parameters were recorded during unaided photopic conditions and mesopic conditions while using 3rd generation plus NVG (ANVIS 9). In the second set of experiments, after the first basal electrophysiological investigation during mesopic conditions using NVG, patients started a 45 days oral treatment, during which they took 3 tablets per day of a food supplement. The tablets contained a mix of anthocyanosides, procyanidolic oligomers, lutein and vitamins A and E. At the end of this treatment, patients were tested again by pattern-reversal VEP investigation during aided vision condition (wearing NVG) in a mesopic environment. RESULTS: VEPs parameters, statistically evaluated using a two tailed paired t-test, showed that latency and amplitude were respectively increased (p < 0.001 and p < 0.01 for 15' and 60' minutes of arc) and decreased (p < 0.05) when measured using NVG with respect to unaided basal conditions. Furthermore, the VEP response in NVG aided vision was positively affected by the oral treatment with the food supplement, showing a significant (p < 0.05) decrease of latency and increase of amplitude. CONCLUSION: The use of NVG impairs the VEP response, and such effect is effectively counteracted by the oral treatment with a food supplement containing a combination of sight improving molecules that might enhance foveal selectivity, central photoreceptors sensitivity and magnocellular fibers effectiveness.

Running behind a tourist: leisure-related skin cancer prophylaxis.

The most important risk factor in the development of skin cancer is exposure to ultraviolet (UV) radiation. Cumulative lifetime UV radiation exposure has been shown to be most important in the pathogenesis of squamous cell carcinoma, whereas intermittent high-dose UV radiation exposure in childhood and adolescence may be more important in the aetiology of basal cell carcinoma and cutaneous malignant melanoma. Using established methodology and best available estimates on UV-related mortality and morbidity, it has been estimated that annually around 1·5 million disability-adjusted life years are lost through excessive exposure to UV radiation. Skin cancer is a significant health problem and its burden is such that it causes the health system more to treat than any other forms of cancer. Prevention is the key action in managing skin cancer at a population level. Investment in prevention programmes such as SunSmart encourages protective behaviours that will reduce the human and financial costs of skin cancer.

Phototherapy and orange-tinted goggles for night-shift adaptation of police officers on patrol.

The aim of the present combined field and laboratory study was to assess circadian entrainment in two groups of police officers working seven consecutive 8/8.5-h night shifts as part of a rotating schedule. Eight full-time police officers on patrol (mean age ± SD: 29.8 ± 6.5 yrs) were provided an intervention consisting of intermittent exposure to wide-spectrum bright light at night, orange-tinted goggles at sunrise, and maintenance of a regular sleep/darkness episode in the day. Orange-tinted goggles have been shown to block the melatonin-suppressing effect of light significantly more than neutral gray density goggles. Nine control group police officers (mean age ± SD: 30.3 ± 4.1 yrs) working the same schedule were enrolled. Police officers were studied before, after (in the laboratory), and during (ambulatory) a series of seven consecutive nights. Urine samples were collected at wake time and bedtime throughout the week of night work and during laboratory visits (1 × /3 h) preceding and following the work week to measure urinary 6-sulfatoxymelatonin (UaMT6s) excretion rate. Subjective alertness was assessed at the start, middle, and end of night shifts. A 10-min psychomotor vigilance task was performed at the start and end of each shift. Both laboratory visits consisted of two 8-h sleep episodes based on the prior schedule. Saliva samples were collected 2 × /h during waking episodes to assay their melatonin content. Subjective alertness (3 × /h) and performance (1 × /2 h) were assessed during wake periods in the laboratory. A mixed linear model was used to analyze the progression of UaMt6s excreted during daytime sleep episodes at home, as well as psychomotor performance and subjective alertness during night shifts. Two-way analysis of variance (ANOVA) (factors: laboratory visit and group) were used to compare peak salivary melatonin and UaMT6s excretion rate in the laboratory. In both groups of police officers, the excretion rate of UaMT6s at home was higher during daytime sleep episodes at the end compared to the start of the work week (p < .001). This rate increased significantly more in the intervention than control group (p = .032). A significant phase delay of salivary melatonin was observed in both groups at the end of study (p = .009), although no significant between-group difference was reached. Reaction speed dropped, and subjective alertness decreased throughout the night shift in both groups (p < .001). Reaction speed decreased throughout the work week in the control group (p ≤ .021), whereas no difference was observed in the intervention group. Median reaction time was increased as of the 5th and 6th nights compared to the 2nd night in controls (p ≤ .003), whereas it remained stable in the intervention group. These observations indicate better physiological adaptation in the intervention group compared to the controls.

Risk, ritual and health responsibilisation: Japan's 'safety blanket' of surgical face mask-wearing.

This article begins to develop an understanding of surgical mask-wearing in Japan, now a routine practice against a range of health threats. Their usage and associated meanings are explored through surveys conducted in Tokyo with both mask wearers and non-mask wearers. It contests commonly held cultural views of the practice as a fixed and distinctively Japanese collective courtesy to others. A historical analysis suggests that an originally collective, targeted and science-based response to public health threats has dispersed into a generalised practice lacking a clear end or purpose. Developed as part of the biomedical response to the Spanish flu of 1919, the practice resonated with folk assumptions as making a barrier between purity and pollution. But mask-wearing became socially embedded as a general protective practice only from the 1990s through a combination of commercial, corporate and political pressures that responsibilised individual health protection. These developments are usefully understood amidst the uncertainty created by Japan's 'second modernity' and the fracturing of her post-war order. Mask-wearing is only one form of a wider culture of risk; a self-protective risk ritual rather than a selfless collective practice.

Ocular hazards of blue-light therapy in dermatology.

Blue-light phototherapy has become important in the treatment of many dermatologic conditions and as a result continue to be developed. Although blue-light therapy is successful, research shows that excessive ocular blue-light exposure may contribute to age-related macular degeneration and other vision problems. As blue-light therapy becomes increasingly more popular for clinical and at-home use, patients and operators of blue-light devices should be aware of its associated ocular hazards. Protective eyewear should be carefully selected and implemented with each therapy session to guard against the development of retinal disease.

An epidemiological perspective of ultraviolet exposure--public health concerns.

Over the last 30 years, many countries have developed strong sun protection programs, spurred on by rapidly increasing skin cancer incidence and concerns about stratospheric ozone depletion. More recently, considerable concern has arisen about widespread vitamin D insufficiency, creating a "sun exposure dilemma," since in most regions vitamin D predominantly derives from endogenous synthesis in the skin initiated by exposure to ultraviolet (UV) radiation. Little attention has been paid to whether a similar dilemma exists for UV-related eye conditions.For the eyes, to our current knowledge, exposure to UV radiation has only adverse effects. There is strong evidence that acute high dose exposure to UV radiation causes photokeratitis and photoconjunctivitis, while even low dose chronic exposure to UV radiation is a risk factor for cataract, pterygium, and squamous cell carcinoma of the cornea and conjunctiva. There is weaker evidence in relation to other conditions, including ocular melanoma and age-related macular degeneration. Ultraviolet radiation-related eye diseases are common, disabling, and cause a considerable disease burden worldwide.The "correct" public health message for optimal sun exposure is not clear cut, with too many variables-ambient UV radiation, personal skin type, age, weight, clothing habits, medication, and others-for a blanket sun safety message. In addition, there remain many unknowns, including strong evidence supporting or refuting the very many proposed health benefits of vitamin D. More evidence is required to define disease burdens for UV-induced eye diseases, to evaluate the decrease in disease burden from sun protective measures and to elucidate any beneficial effects of exposure of the eye to UV radiation, to provide appropriate advice to the public.
