[Ab] Abstract:Since 1800s there are reports of post-traumatic anosmia, but few studies investigated post-traumatic gustatory deficit and adopted validated evaluation tests. Peripheral and/or central mechanisms may be involved in the genesis of post-traumatic gustatory dysfunction. Beyond a reduction/loss (hypogeusia/ageusia) of gustatory function following a trauma, qualitative taste changes (dysgeusia) may occur. Especially when persistent, taste deficits might be particularly relevant for patient's quality of life and activities of daily life, but knowledge on this topic is limited. Fifty-three consecutive patients with previous head trauma were recruited. Every patient underwent a careful history taking and thorough olfactory and gustatory chemosensory testing by Sniffin'Sticks Extended test, Whole Mouth Test and Taste Strips Test. All patients had olfactory abnormalities (hyposmia: n = 10, functional anosmia: n = 43), while 10 of them (19%) showed taste deficits (dysgeusia: n = 3, dysgeusia with hypogeusia: n = 1, hypogeusia: n = 5, ageusia: n = 1). Here, we report clinical and neuroimaging data and detailed description of four meaningful cases representing central and peripheral injury patterns. Chemosensory evaluation might be useful to explore taste disorder, a still neglected and underestimated sequela of head trauma.

[Ab] Abstract:This study investigated the relation of the fungiform taste papillae density and saliva composition with the taste perception of patients suffering from diagnosed taste disorders. For this purpose, 81 patients and 40 healthy subjects were included. Taste was measured by means of regional and whole mouth chemosensory tests, and electrogustometry. Olfaction was assessed using the Sniffin Sticks. Fungiform papillae were quantified using the "Denver Papillae Protocol for Objective Analysis of Fungiform Papillae". In addition, salivary parameters [flow rate, total proteins, catalase, total anti-oxidative capacity (TAC), carbonic anhydrase VI (caVI), and pH] were determined and the Beck Depression Inventory was administered. Patients showed less taste papillae compared to healthy subjects. The number of papillae correlated with total taste strip score and salivary flow rate. Regarding salivary parameters, the flow rate, protein concentration, and TAC of patients were higher compared to controls. In addition, salivary flow rate, protease, caVI, and catalase values correlated with the summed taste strip score. Regarding various taste disorders, salty-dysgeusia patients showed the lowest taste test scores compared to those with bitter or metal-dysgeusia. Olfactory function of patients was significantly worse compared to healthy controls. This difference was most pronounced for ageusia patients. Compared to controls, patients also exhibited higher depressive symptoms. The density of fungiform papillae seemed to be positively associated with taste perception. Furthermore, patients exhibited changes in saliva composition (higher salivary flow rate, increased protein concentration, proteolysis, and TAC) compared to controls indicating that assessment of saliva may be critical for the diagnostic procedure in taste disorders.

[Ab] Abstract: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. Testing for gustation involves evaluating thresholds and discrimination of five basic tastes (salty, sweet, bitter, sour, and umami). The presence of a specific pattern of loss in both olfaction and gustation in PD has been proposed, but this has not yet been confirmed. Within PD, olfactory loss is strongly tied with cognitive status though links to other features of PD or a particular PD phenotype is debated. Hyposmia is more often present and typically more severe in PD patients than other parkinsonian syndromes, making it a potentially useful biomarker for the disease.

[Ti] Title:Loss of Smell and Taste After General Anesthesia: A Case Report.

[Ab] Abstract: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.

[Ab] Abstract:Chemosensory function, burning sensations in the tongue (BST), halitosis, saliva secretion, and oral health-related quality of life (OHRQoL) were investigated in patients with primary Sjögren's syndrome (pSS). In 31 patients with pSS and 33 controls, olfactory and gustatory functions were evaluated. Self-reported complaints of dysgeusia, BST, and halitosis were recorded. Saliva secretion rates were measured and OHRQoL was assessed using the short-form Oral Health Impact Profile (OHIP-14). Patients had significantly lower olfactory (8.8 ± 3.5 vs. 10.7 ± 1.2) and gustatory (18.9 ± 7.1 vs. 25.4 ± 4.3) scores than controls, and significantly more patients complained of dysgeusia (58.1% vs. 0%), BST (54.8% vs. 6.1%), and halitosis (41.9% vs. 0%). A significantly greater proportion of patients with pSS had ageusia (19% vs. 0%), hypogeusia (32% vs. 12%), anosmia (13% vs. 0%), or hyposmia (29% vs. 9%). Significantly lower saliva secretion rates (ml min ) were observed in patients with pSS for stimulated (0.62 ± 0.40 vs. 1.57 ± 0.71) and unstimulated (0.08 ± 0.07 vs. 0.29 ± 0.17) saliva. The mean OHIP-14 score was significantly higher in patients with pSS (16.2 ± 10.8 vs. 2.7 ± 3.1) and was positively correlated with dysgeusia, BST, and halitosis. In conclusion, patients with pSS reported higher occurrence of dysgeusia, BST, and halitosis, and demonstrated relatively impaired chemosensory and salivary functions. The patients' poorer OHRQoL was associated with dysgeusia, BST, and halitosis.

[Ti] Title:Historical Perspectives on Ancient Greek Derived "a" Prefixed Nomenclature for Acquired Neurocognitive Impairment.

[Ab] Abstract:Distinct forms of acquired neurocognitive impairment are often described by "a" prefixed terms that derive from ancient Greek (and in one case Latin). Two modern English language neurological and neuropsychological reference books were searched to identify 17 such terms in contemporary usage: amnesia, akinesia, ataxia, aphasia, agraphia, anosmia, apraxia, athetosis, ageusia, achromatopsia, agnosia, alexia, amusia, anomia, anarthria, anosognosia, and acalculia. These were traced to their initial association with acquired neurocognitive impairment in German, English, and French language medical publications from the late 18th, 19th, and early 20th centuries (1770 through 1920). Some of these terms (e.g., agnosia) were used in ancient Greek, although not associated with neurocognitive impairment. The remainder constitute novel semantically plausible (e.g., anosmia) and unclear (e.g., alexia) formulations. In the localizationist thinking of the time, neurocognition was conceived as being organized within specialized "centers" in specific locations connected by pathways within the brain.

[Ab] Abstract:A 63-year-old man noticed hypogeusia after presenting hiccups for several days. He was serologically diagnosed with varicella-zoster virus (VZV) infection, but had no skin lesions typical of herpes (zoster sine herpete). Hypogeusia was confirmed by electrogustometry and the filter-paper disk method, which showed damage in the areas innervated by the cord of tympanum, glossopharyngeal nerve, and greater petrosal nerve. High signals in the nuclei of the solitary tract of the medulla oblongata and the enhancement of the bilateral intracranial segments of the cranial nerve IX and X complex were observed by magnetic resonance imaging (MRI). The signal changes in the nuclei of the solitary tract on MRI were seen for more than 2 months, and hypogeusia lasted for more than 7 months. Hypogeusia caused by VZV infection has rarely been reported; however, similar cases could have gone undiagnosed or underdiagnosed in patients with idiopathic hypogeusia.

[Ti] Title:A genetic marker of the ACKR1 gene is present in patients with Type II congenital smell loss who have type I hyposmia and hypogeusia.

[Ab] Abstract:PURPOSE: Our previous study of Type II congenital smell loss patients revealed a statistically significant lower prevalence of an FY (ACKR1, formerly DARC) haplotype compared to controls. The present study correlates this genetic feature with subgroups of patients defined by specific smell and taste functions. METHODS: Smell and taste function measurements were performed by use of olfactometry and gustometry to define degree of abnormality of smell and taste function. Smell loss was classified as anosmia or hyposmia (types I, II or III). Taste loss was similarly classified as ageusia or hypogeusia (types I, II or III). Based upon these results patient erythrocyte antigen expression frequencies were categorized by smell and taste loss with results compared between patients within the Type II group and published controls. RESULTS: Comparison of antigen expression frequencies revealed a statistically significant decrease in incidence of an Fy haplotype only among patients with type I hyposmia and any form of taste loss (hypogeusia). In all other patient groups erythrocyte antigens were expressed at normal frequencies. CONCLUSIONS: Data suggest that Type II congenital smell loss patients who exhibit both type I hyposmia and hypogeusia are genetically distinct from all other patients with Type II congenital smell loss. This distinction is based on decreased Fy expression which correlated with abnormalities in two sensory modalities (hyposmia type I and hypogeusia). Only patients with these two specific sensory abnormalities expressed the Fy antigen (encoded by the ACKR1 gene on the long arm of chromosome 1) at frequencies different from controls.

[Ab] Abstract:To explore the clinical characteristics of patients with olfactory dysfunction after upper respiratory tract infection. Through clinical specialist examination and imaging examination, 95 cases of patients with olfactory dysfunction after upper respiratory tract infection were confirmed, 58 cases in anosmia group and 37 cases in hyposmia group. All were performed by a subjective olfactometry (Sniffin'Sticks test) and a subjective taste function tests. The results were statistically analyzed by SPSS 17.0 software. In 58 cases of anosmia group, 21 cases of male, 37 cases of female; Twenty-six cases of youth, 23 cases of middle age, 9 cases of old age; Twenty-seven cases occurs in spring, 11 cases in summer, 12 in autumn and 8 in winter. Among 37 cases of hyposmia group, 12 cases of male, 25 cases of female; Eighteen cases of youth, 16 cases of middle age, 3 cases of old age; Fourteen cases occurs in spring, 8 cases in summer, 7 in autumn and 8 in winter. There was no statistically significant difference in gender, age and the onset season between the two groups(χ =0.142, >0.05; χ =1.124, >0.05; χ =1.335, >0.05). In anosmia group, with 4 cases of ageusia, 22 cases of hypogeusia, 32 cases of normal taste; in hyposmia group, with 0 cases of ageusia, 10 cases of hypogeusia, 27 cases of normal taste. There were significant differences between the two groups with different types of taste disorder(Pearson correlation coefficient =0.210, <0.05), it was positive correlation. It is suggested that after the upper respiratory tract infection, the olfactory dysfunction is often accompanied by the sense of taste dysfunction, the more severe the damage of olfactory function, the degree of damage to the taste function is also increased. Olfactory impairment degree exhibited no relationship with gender, age or onset seasons.
