OBJECTIVES: Tobacco smoke exposure (TSE) is associated with many adverse health outcomes. The goal of this study was to provide insight into the prevalence and location of self-reported TSE outside the home for US adults and children. STUDY DESIGN: Cross-sectional survey. METHODS: Data from a nationally representative sample of US adults from 2014 were included. Participants who responded that they smelled smoke during the past seven days in various settings were considered to have been exposed to TSE...

Anosmia, the loss of sense of smell, is a common nonmotor feature of Parkinson's disease (PD). Ageusia, the loss of sense of taste, is additionally an underappreciated nonmotor feature of PD. The olfactory tract is involved early in PD as indicated by frequent occurrence of hyposmia or anosmia years or decades before motor symptoms and by autopsy studies showing early synuclein pathology in the olfactory tract and anterior olfactory nucleus even in the early stages of PD. Testing for olfaction consists of evaluation of olfactory thresholds, smell identification and discrimination, and olfactory memory...

BACKGROUND: Kallmann syndrome (KS) is an isolated form of hypogonadotrophic hypogonadism (HH) in combination with a defect in olfactory function. The diagnosis of KS before maturation is often difficult to make due to the broad spectrum of presentation and genetic heterogeneities. ENT examination including smell test is essential for proper diagnosis of olfactory disturbances and non olfactory abnormalities in craniofacial region which may also be existent in KS. CASE: A 17-year-old girl admitted to ENT Department because of the olfactory sense disturbances since two years...

We present a rare case of a large infarcted submucous fibroid removed manually after a normal vaginal delivery. This patient was known to have a large postero-fundal hybrid predominantly intramural uterine fibroid, measuring 11 x 10 cm in diameter and diagnosed 2 years prior to last conception. Thirty-five days postpartum, she presented with severe lower abdominal pain and foul smell per vaginum. Abdominal examination revealed a very tender bulky uterus at 24 weeks size, and vaginal examination revealed a big fleshy smelly mass with friable surface just bulging from a dilated cervix...

A thin film of poly-([IrCl(cod)(NHC-onbe)]n-(propyl-onbe)m) (onbe= oxanorbornene) coated on filter paper reacts quantitatively with CO to yield 1,5-cyclooctadiene, whose unpleasant smell can be detected by the human olfactory system with very high sensitivity. Odorless, but toxic CO is thus "translated" into the distinct smell of 1,5-cyclooctadiene. Based on malodorogenic sensing it is possible to smell the presence of CO.

While domestic dogs, Canis familiaris, have been found to be skillful at social cognitive tasks and even some meta-cognitive tasks, they have not passed the test of mirror self-recognition (MSR). Acknowledging the motivational and sensory challenges that might hinder performance, even before the question of self-recognition is broached, this study creates and enacts a novel design extrapolated from the species' natural behaviour. Given dogs' use of olfactory signals in communication, this experiment presents dogs with various canisters for approach and investigation...

Malgorzata Teodorowicz, Joost van Neerven, Huub Savelkoul
The majority of foods that are consumed in our developed society have been processed. Processing promotes a non-enzymatic reaction between proteins and sugars, the Maillard reaction (MR). Maillard reaction products (MRPs) contribute to the taste, smell and color of many food products, and thus influence consumers' choices. However, in recent years, MRPs have been linked to the increasing prevalence of diet- and inflammation-related non-communicable diseases including food allergy. Although during the last years a better understanding of immunogenicity of MRPs has been achieved, still only little is known about the structural/chemical characteristics predisposing MRPs to interact with antigen presenting cells (APCs)...

Patients with CKD suffer from food aversion, anorexia, and malnutrition. Although olfaction has a significant role in determining food flavor, our understanding of olfactory impairment and of the olfaction-nutrition axis in patients with kidney disease is limited. We quantified odor identification, odor threshold, and subjective odor perception in a cohort (n=161) comprising 36 participants with CKD, 100 participants with ESRD, and 25 controls. We investigated olfaction-nutrition associations in these participants and examined a novel intervention to improve olfaction in ESRD...

We report the case of a fisherman who was exposed to high concentrations of hydrogen sulfide (H2S) gas from the fish garbage room. The patient survived and was discharged with full recovery from the hospital. H2S is a colourless, foul smelling and highly toxic gas next to carbon monoxide, which causes inhalation death. It is a by-product of various industrial processes particularly involves exposure from agriculture, petrochemical industry and organic matter decomposition from sewage processing. It is a by-product of H2S has been referred as the "knock down gas" because inhalation of high concentrations can cause immediate loss of consciousness and death...

Olfaction plays an important role in the perception of our environment. Smell impairment is known to be a manifestation of several autoimmune diseases. Similarities between the olfactory and immune systems and previously published human studies and animal models of autoimmune diseases account for the accumulating evidence for this observation. In this review, we will present the current literature concerning olfactory dysfunction in autoimmune diseases, discuss clinical aspects and provide new insights regarding pathogenesis and possible mechanisms...

Dario Krpan
On a daily basis, people are exposed to numerous stimuli, ranging from colors and smells to sounds and words, that could potentially activate different cognitive constructs and influence their actions. This type of influence on human behavior is referred to as priming. Roughly two decades ago, behavioral priming was hailed as one of the core forces that shape automatic behavior. However, failures to replicate some of the representative findings in this domain soon followed, which posed the following question: "How robust are behavioral priming effects, and to what extent are they actually important in shaping people's actions?" To shed a new light on this question, I revisit behavioral priming through the prism of a dynamical systems perspective (DSP)...

This case report describes a patient, who lost the ability to smell and taste after receiving a propofol-based general anesthesia for a laparoscopic inguinal hernia repair. Immediately after the procedure, the patient had anosmia (loss of smell), ageusia (loss of taste), and light dysphagia. Assessment by an otorhinolaryngologist and the results of a magnetic resonance imaging could not clarify the pathology behind these symptoms. Although there are several plausible explanations for the patient's anosmia and ageusia (eg, cerebral infarcts, nerve damage, chronic sinusitis), the most likely explanation is an uncommon adverse drug reaction to the anesthetic agents used during the procedure...

The raw materials used to make oolong tea (Camellia sinensis) are a combination of leaf and stem. Oolong tea made from leaf and stem is thought to have a more aromatic smell than leaf-only tea. However, there is no available evidence to support the viewpoint. In this study, sensory evaluation and detailed characterization of emitted and internal volatiles (not readily emitted, but stored in samples) of dry oolong teas and infusions indicated that the presence of stem did not significantly improve the total aroma characteristics...

Evidence that experiences of nature can benefit people has accumulated rapidly. Yet perhaps because of the domination of the visual sense in humans, most research has focused on the visual aspects of nature experiences. However, humans are multisensory, and it seems likely that many benefits are delivered through the non-visual senses and these are potentially avenues through which a physiological mechanism could occur. Here we review the evidence around these lesser studied sensory pathways-through sound, smell, taste, touch, and three non-sensory pathways...

Cold pressed oils from huanglongbing (HLB) symptomatic (SY) and asymptomatic (AS) Hamlin and Valencia oranges were assessed for 2 y (2014 to 2015 and 2015 to 2016 seasons) with 2 harvest dates for each orange variety per year. Physicochemical properties (optical rotation, aldehyde content, ultraviolet [UV] absorbance, refractive index, and specific gravity) mandated by the United States Pharmacopeia (USP) for orange oil quality were assessed. Hamlin and Valencia oils showed minor differences in physicochemical properties based upon disease stage...

Carbon monoxide (CO) poisoning is one of the most common types of poisoning causing death worldwide. In our country, it occurs particularly during winter as a result of leak from stove or water heater, or as result of inhalation during a fire. Although most poisonings occur accidentally, some cases are suicide attempt. As CO is a substance that is not visible and has no taste or smell and is therefore difficult to detect, the gas can be a "silent killer" that is not noticed until effects develop. CO reacts with oxygen, creating carboxy hemoglobin (COHb), which leads to tissue hypoxia...

Introduction  Epidermoid tumors represent approximately 0.3 to 1.8% of all intracranial brain tumors. Only 1.5% of all intracranial epidermoid cysts (ECs) invade the brain and secondary epilepsy is extremely rare. Since August 2014, a 59-year-old male smoker had been presenting bad smell feelings, totaling four episodes with sudden onset and duration of 2 minutes. On September 2014, after a sense of smell episode, it evolved into loss of contact and automatic movements followed by generalized tonic-clonic movements...

We compared the concentrations of Escherichia coli quantified with Colilert(™) and the compartment bag test (CBT) in source water and household stored drinking water (SDW) in 35 households in western Kenya. We also investigated the associations of the perceptions of organoleptic properties and overall quality with ≥ 1 MPN/100 mL E. coli in SDW. Participants who rated the taste or smell of their SDW "< 5" on a 1 = "poor" to 5 = "excellent" Likert scale were 8.71 or 7.04 times more likely, respectively, to have ≥ 1 MPN/100 mL E...

Renal transplantation is the treatment of choice for end-stage renal disease, during which renal grafts from deceased donors are routinely cold stored to suppress metabolic demand and thereby limit ischemic injury. However, prolonged cold storage followed by reperfusion induces extensive tissue damage termed cold ischemia/reperfusion injury (IRI) and puts the graft at risk of both early and late rejection. The underlying mechanism of IRI is not completely understood and a reliable/ suitable method to protect the renal graft against cold IRI is lacking...

The addition of desiccated beef liver to infant and young child complementary foods can be used to overcome nutrient deficits, however its acceptability is unknown. We conducted a series of studies to test the acceptability of complementary foods fortified with either powdered beef liver, beef meat, beef liver + meat or placebo among 96 Indonesian children aged 12 to 23 mo. This was achieved by determining liking of a single test food with added study powder, followed by a 2-wk home trial and focus group discussions to assess liking during repeated consumption of the study powders added to daily meals...
