BACKGROUND: Besides intraocular pressure, vascular factors play a role in the pathogenesis of glaucomatous optic neuropathy. One of these potential vascular factors is Flammer syndrome. The purpose of the present study was to determine in a Korean population whether signs and symptoms of Flammer syndrome occur more often in normal tension glaucoma patients than in control subjects. METHODS: Two hundred forty-six normal tension glaucoma patients and 1116 control subjects responded to a multiple-choice questionnaire asking about 15 signs and symptoms of Flammer syndrome...

REVIEW
Josef Flammer, Katarzyna Konieczka
This review describes the clinical and basic research that led to the description of Flammer syndrome. It is narrated from a personal perspective. This research was initiated by the observation of an increased long-term fluctuation of visual fields in a subgroup of glaucoma patients. As these patients had strikingly cold hands, peripheral blood flow was tested with a capillary microscopy, and vasospastic syndrome (VS) was diagnosed. Further studies on these patients revealed frequently weakened autoregulation of ocular blood flow and increased flow resistivity in retroocular vessels...

Partially remediated gray (reuse) water will likely find increasing use in a variety of applications owing to the increasing scarcity of freshwater. We aimed to determine if a model fish, the goldfish, could sense reuse water using olfaction (smell), and if 30min or 7d (acute) and 60d (sub-chronic) exposures would affect their olfactory responses to natural odorants. We examined olfaction as previous studies have found that numerous chemicals can impair the olfactory sense, which is critical to carrying out numerous life-sustaining behaviors from feeding to mating...

BACKGROUND: The sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available. OBJECTIVE: The purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants...

BACKGROUND: Revision endoscopic sinus surgery (RESS) may be required for partially controlled or uncontrolled chronic rhinosinusitis. Studies that reported technical success, e.g., sinus ostia patency after RESS, do not address whether the patient's symptoms and quality of life (QOL) improve after surgery. However, patient-reported outcome measures (PROM) are useful to assess the impact of sinus surgery on a patient's symptoms and QOL. OBJECTIVE: This systematic review was undertaken to evaluate the impact of RESS on PROMs...

BACKGROUND: The sense of smell is very influential in the taste of foods. If the smell pleases us, we anticipate the taste of the food with a great deal of relish. If our sense of smell is impaired, so is our taste. The effect of appliance on taste perceptions has always had a controversial subject. MATERIALS AND METHODS: The present study was designed to analyze the change in taste perception in children using removable orthodontic appliances. All the selected volunteers were given different taste stimuli and were asked to score as per their perception...

Once associating another person with an unpleasant smell, how do we perceive and judge this person from that moment on? Here, we used aversive olfactory conditioning followed by a social attribution task during functional magnetic resonance imaging to address this question. After conditioning, where one of two faces was repeatedly paired with an aversive smell, the participants reported negative affect when viewing the smell-conditioned but not the neutral face. When subsequently confronted with the smell-conditioned face (without any smell), the participants tended to judge both positive and negative behaviors as indicative of personality traits rather than related to the situation...

Disgust is part of a behavioral immune system that helps to detect pathogens. One important input to this system is the sense of smell. We conducted an experiment on body odor perception with 72 participants (35 men, 37 women; mean age = 24 years), who had been divided according to high versus low disgust proneness. All participants were exposed to six samples of axillary sweat from other individuals and to their own sweat. They were asked to identify their own body odor and to rate their affective experience...

Transfusion-dependent thalassemia (TDT) is a group of thalassemia syndromes that require regular blood transfusions for survival. It is unknown whether the sense of smell of patients with TDT is affected, and if so, whether smell loss has an adverse effect on quality of life (QOL). Olfactory thresholds were measured using Snap & Sniff(®) wands. QOL was assessed via the Short Form-36 (SF-36) questionnaire. Forty-two TDT patients from the Thalassemia Center in Istanbul Medical Faculty were tested (mean age 26...

Stomach distension and energy per time are factors influencing satiety. Moreover, different rates of nutrient intake induce different stomach distension. The goal of our studies was to elucidate the influence of different oral rates of nutrient intake (normal rate versus slow intervalled rate; study I) and intravenous low rate macronutrient application (protein, carbohydrate, fat) or placebo (study II) on psychophysical function. The pilot studies investigated the effects of 1) study I: a mixed nutrient solution (1/3 protein, 1/3 fat, 1/3 carbohydrates) 2) study II: intravenous macronutrient infusions (protein, carbohydrate, fat) or placebo on psychophysical function (mood, hunger, food craving, alertness, smell intensity ratings and hedonic ratings) in human subjects...

BACKGROUND: Septal surgery (SP) is one of the most frequently performed operations in Germany and thus represents a high cost burden for the health system. However, sufficient data on postoperative patient satisfaction and objective indication criteria for surgery are still lacking. OBJECTIVE: This study aimed to determine postoperative patient satisfaction and possible factors influencing the subjective success of SP, in order to optimize preoperative indication establishment...

Perceptual learning refers to how experience can change the way we perceive sights, sounds, smells, tastes, and touch. Examples abound: music training improves our ability to discern tones; experience with food and wines can refine our pallet (and unfortunately more quickly empty our wallet), and with years of training radiologists learn to save lives by discerning subtle details of images that escape the notice of untrained viewers. We often take perceptual learning for granted, but it has a profound impact on how we perceive the world...

On the morning of April 9, 2015, citizens in Vancouver (British Columbia, Canada) awoke to the sight and smell of oil on the shores of popular downtown beaches. Because the oil also had spread over the shallow seawater intakes for the Vancouver Aquarium, a preliminary screening of samples was performed as a prompt, first response to assess the risks to the Aquarium collection and guide the emergency operational response. A subsequent, more detailed examination for the presence of spilled oil in sediment, biota and water samples from the Vancouver Harbour region was then conducted based on the analysis of a large suite of alkanes, petroleum biomarkers, parent polycyclic aromatic hydrocarbons (PAHs) and alkyl PAH isomers...

Most children's toys on the market are primarily made out of plastic and other complex composite materials. Consumer complaints about offensive odors or irritating effects associated with toy products have increased in recent years. One example is the strongly perceivable negative odor reported for a particular series of toy swords. Characterizing the presence of contaminants, including those that have the potential to be deleterious to health, in such products is a significant analytical challenge due to the high baseline abundance of chemical constituents of the materials used in the products...

As diverse environmental changes continue to influence the structure and function of plant-pollinator interactions across spatial and temporal scales, we will need to enlist numerous approaches to understand these changes. Quantitative examination of floral volatile organic compounds (VOCs) is one approach that is gaining popularity, and recent work suggests that floral VOCs hold substantial promise for better understanding and predicting the effects of environmental change on plant-pollinator interactions...

Domestic dogs (Canis familiaris) use urine to communicate among themselves, however, it is unknown whether the gonadectomy (neutering or spaying) of a dog affects this communication in anyway. Urine samples from 10 intact and 10 gonadectomised, unfamiliar dogs were presented to 12 tester dogs to sniff under controlled conditions in a pilot study. The amount of time the tester dogs spent sniffing each sample was recorded. Overall, tester dogs were recorded smelling the urine of gonadectomised individuals for a longer time...

The conceptual framework of 'therapeutic landscapes' has been used as a means of considering the significance of specific environments, spaces, and places for aspects of health. Building on a growing attention to the sensory elements of spaces of health and wellbeing, this article mobilises empirical research on 'care farming' practices to discuss how smellscapes come to be crucial in fulfilling anticipations, imaginations, and expectations of a 'therapeutic space'. This article highlights how embodied relationships with specific scents can constitute a therapeutic encounter with place, actively influencing practices and engagement with(in) place, and the ways by which place can have a meaningful affect on health...
