The Impact of Olfactory Disorders in the United Kingdom

Olfactory disorders are believed to affect 5% of the general population and have been shown to bear significant psychosocial consequences to sufferers. Although more common than blindness and profound deafness in the United Kingdom, the impact of these disorders has not been assessed to date and the plight of British patients has yet to be quantified. In 2012, a patient support organization, Fifth Sense, was founded to provide information and support to sufferers of chemosensory disorders. Following a recent members conference, a survey of the membership was conducted anonymously using a series of questions based on an existing olfactory disorders questionnaire. From 496 respondents, this has demonstrated high rates of depression (43%) and anxiety (45%), impairment of eating experience (92%), isolation (57%), and relationship difficulties (54%). Women appear to have significantly more issues than men in terms of social and domestic dysfunction relating to olfactory loss (P = 0.01). Qualitative disorders also affected more than 1 in 5 members with parosmia reported in 19% and phantosmia in 24%. This paper discusses the details of the British story of anosmia and other related disorders as depicted by those most affected

Psychic euosmia and obsessive compulsive personality disorder

Patients with obsessive compulsive personality disorder (OCPD) often refer to a prompt mood improvement upon encountering good scents in general, or fresh laundry borax on their clothes, pillows or home settings. The Authors propose the new term psychic euosmia in the mean of an overstated psychological predisposition for a real pleasant smell that elicits an immediate sense of pleasure, order and calm. The prompt reactions to a pleasant odor might be explained by the involvement of rhinencephalon and its proximity to mood-related limbic circuits, which bypass the cognitive awareness. Cleanliness may not preclude a subject to enjoy a good smell, even if we are representing smells that resemble freshness, in other words order. A potentially even more important argument is given by the continuum of personality disorders and their variability. Not all personality characteristics led to disturbed behaviors. In evolutionary perspectives having the ability to differentiate between unpleasant and pleasant odors should have made the difference in surviving. On the other hand, psychic euosmia could be considered a normal reaction, but in our clinical experience it is over-represented among OCPD subjects with marked orderliness and disgust. Therefore, detecting psychic euosmia might vicariously confirm the relevance of disgust as a cognitive driver of OCPD. Hereby we support research to characterize psychic euosmia as a feature of orderliness and cleanliness for OCPD

Smell and taste disorders in the UK: first experiences with a specialised smell and taste outpatient clinic

Olfactory dysfunction is common, affecting 1‐5% of those under the age of 60 1 and at least 20% of those aged more than 60 years. 2 In many UK centres, the approach to it is variable and routine olfactory testing is not performed, as noted by a recent survey of British ENT surgeons. 3 This is in contrast to Europe and the USA, where many specialist smell and taste centres already exist

Position Paper on Olfactory Dysfunction

Background: Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst full recommendations are outlined in the main document, key points include: -Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy. -Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability. -Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour threshold, and/or one of odour identification or discrimination. -Comprehensive chemosensory assessment should include gustatory screening. -Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions: We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field

How does VTE risk for the patch and vaginal ring compare with oral contraceptives?

Evidence is conflicting with regard to the comparative frequency of venous thrombolic events (VTE) among women using the transdermal patch when compared to an oral contraceptive (OC), even though the patch produces a relatively high serum ethinyl estradiol (EE) level (strength of recommendation [SOR]: C, conflicting cohort case-control studies). The vaginal ring has a risk of VTE comparable to that of an OC (SOR: B, 1 comparative study)

Oral malodor in Special Care Patients: current knowledge

Epidemiological studies report that about 50% of the population may have oral malodor with a strong social and psychological impact in their daily life. When intra-oral causes are excluded, referral to an appropriate medical specialist is paramount for management and treatment of extra-oral causes. The intra-oral causes of halitosis are highly common, and the dentist is the central clinician to diagnose and treat them. Pseudohalitosis or halitophobia may occur and an early identification of these conditions by the dentist is important in order to avoid unnecessary dental treatments for patients who need psychological or psychiatric therapy. The organoleptic technique is still considered the most reliable examination method to diagnose genuine halitosis. Special needs patients are more prone than others to have oral malodor because of concurrent systemic or metabolic diseases, and medications. The present report reviews halitosis, its implications, and the management in special care dentistry

CLINICAL FEATURES IN RUSSIAN PATIENTS WITH COVID-ASSOCIATED PAROSMIA/PHANTHOSMIA

Background: Olfactory dysfunction is a typical symptom of COVID-19 infection. While COVID-associated anosmia is welldescribed, knowledge of parosmia (olfactory distortions) and phanthosmia (olfactory hallucinations) is relatively lacking. We undertook a clinical study of the parosmia/phanthosmia phenotype, aiming to support improved prediction and management of these symptoms. Subjects and methods: In a cross-sectional study between September 2020 and May 2021, we recruited 187 COVID-19 patients with parosmia/phanthosmia via social media and a matched healthy control group from neurologists. The patients received an online video-consultation with a neurologist trained in olfactory research and completed a questionnaire to assess the nature of their subjective olfactory disorder. Results: In the acute period of COVID-19 parosmia/phanthosmia, patients often experienced comorbid manifestations such as fatigue, fever, headache, myalgia, and "brain fog". Isolated phanthosmia was observed in 13.9% of acute COVID-19 patients, as compared to 34.2% in the long term. Parosmia was described in 89.8% of patients in the long-term course of the disease. COVIDassociated parosmia/phanthosmia was more common in women (81.3%) than men (18.7%). Almost all parosmia/phanthosmia patients had an acute history of anosmia, which often progressed to hyposmia. A third of the patients had a history of taste disturbance The long-term COVID-19 sequelae such as fatigue, brain fog, and dizziness are significantly more common among patients with parosmia/phanthosmia, as were autonomic symptoms such as awareness of heartbeat and rapid pulse. The incidence of migraine with aura was significantly higher in the parosmia/phanthosmia group than in the control group (8% versus 0.9%). The allergy was reported significantly more frequent in the study group compared to the control group. Conclusions: Qualitative olfactory disorders occur frequently in COVID-19 patients. Those with the parosmia/phanthosmia phenotype have a higher risk for other symptoms, notably headache (including migraine with aura), fatigue, brain fog, dizziness, and cardiovascular/autonomic manifestations, as well as allergy. We suppose that further investigation of this phenomenon will reveal phenotypic variants depending on particular symptoms cluster; improved nosology of qualitative olfactory disorders in COIVD-19 is a prerequisite for establishing appropriate treatments
