Pleomorphic adenoma of the lateral nasal wall: case report.

2008

Pleomorphic adenoma is the most common tumour of the salivary glands. However, it is extremely rare for these to originate in the nose and even when they do so, it is most commonly in the nasal septum. It is important to be aware of the paucity of presenting symptoms (nasal obstruction and epistaxis), as the lesion may not be recognized immediately. Growth is generally restricted locally and the tumour is not known to spread to the neighbouring structures. Surgical resection is the treatment of choice. Recurrences and evolution to malignancy are not frequent, but long-term follow-up is recommended. The case is presented of pleomorphic adenoma arising from the lateral wall of the right nasal…

Olfactory Dysfunction After Head Injury

2008

Objective: To determine the incidence of olfactory dysfunction after head trauma using clinical and radiologic findings, quantitative assessment, and electro-physiologic methods. Participants: A total of 190 patients with head trauma of different severity (n = 32 with mild traumatic brain injury (TBI), n = 94 with signs of moderate TBI, and n = 64 with severe TBI) 6 to 32 months prior to the study. Design: Patients were selected retrospectively, surveyed by telephone (n = 190), and screened for olfactory function with Brief Smell Identification Test (n = 82). Those with olfactory dysfunction were assessed as outpatients using the Sniffin' Sticks (n = 19) and olfactory-evoked potential recor…

Stimulation of Spermatogenesis and Biological Paternity by Intranasal (Low Dose) Gonadotropin-Releasing Hormone (GnRH) in a Male with Kallmann's Synd…

1987

Intranasal (in) GnRH spray caused induction and maintenance of spermatogenesis and biological paternity in a 28-yr-old man with Kallmann's syndrome. Prior treatment had included GnRH analog administration, which failed to induce puberty, and testosterone (T) enanthate weekly. Prior hCG/human menopausal gonadotropin therapy had resulted in high normal serum T levels and near-normal semen quality, but during subsequent hCG therapy, spermatogenesis markedly decreased. The patient had then received 250 mg T enanthate/month for 2 yr and 7 months; it was discontinued 7 weeks before the in GnRH study began. At its start (July 1984) the subject's testis size was 7 mL, and he had azoospermia, low se…

The Candy Smell Test in Clinical Routine

2011

Background The “Candy Smell Test” (CST) has been introduced as a new testing method for the evaluation of the human sense of smell. In contrast to other established orthonasal smell tests, the CST addresses the retronasal application of odors, typical for food aroma effects during mastication and swallowing. The aim of this study was to evaluate the CST in a clinical setting in patients with olfactory dysfunction and normal controls against the Sniffin’ Sticks test. Furthermore, cutoff points for normal and pathological results in the CST should be determined. Methods The olfactory performance of 96 patients presenting with olfactory disorders and 71 healthy controls was evaluated with the …

Comparison of subjective olfaction ratings in patients with and without olfactory disorders

2012

AbstractObjective:Olfactory dysfunction is common. The reliability of self-assessment tools for smell testing is still controversial. This study aimed to provide new data about the accuracy of olfactory self-assessment compared with a standardised smell test.Design:Prospective, controlled, cohort study of patients with olfactory disorders and healthy controls.Subjects:Ninety-six patients with a smell deficit and 71 controls were asked to rate their sense of smell on a visual analogue scale. Their olfactory abilities were also evaluated with the Sniffin' Sticks tests.Results:The whole cohort showed a significant correlation between visual analogue scale smell scores and Sniffin' Sticks total…

An Online Observational Study of Patients With Olfactory and Gustory Alterations Secondary to SARS-CoV-2 Infection

2020

Introduction: Since the beginning of the Covid-19 epidemic produced by SARS2-Cov virus, olfactory alterations have been observed at a greater frequency than in other coronavirus epidemics. While olfactory alterations may be observed in patients with rhinovirus, influenza virus, or parainfluenza virus infection, they are typically explained by nasal obstruction with mucus or direct epithelial damage; in the case of SARS-CoV-2, olfactory alterations may present without nasal congestion with mucus. We performed a study of patients presenting olfactory/gustatory alterations in the context of SARS-CoV-2 infection in order to contribute to the understanding of this phenomenon. Material and Method…

Olfaction in chemotherapy for head and neck malignancies

2015

Abstract Objective Systemic chemotherapy for different malignancies occurs alongside various side effects, including reduced sensory function. To date, little is known about the effect of chemotherapeutic agents on olfaction. The aim of this study was to provide new data about changes in sense of smell during chemotherapy among patients with advanced squamous cell carcinomas of the head and neck region. Methods In a prospective, controlled cohort study of patients undergoing up to three courses of chemotherapy (cis- or carboplatin, 5-fluorouracil and docetaxel), olfaction was evaluated prior to and directly following completing a cycle, as well as 3 weeks later with the beginning of the nex…

Osmophobia as an early marker of migraine: a follow-up study in juvenile patients.

2012

Background: Osmophobia is frequent in children with migraine (20–35%) but can also occur in up to 14% of cases with tension-type headache (TTH). So far, the prognostic role of this symptom in children with primary headaches has never been evaluated. Methods: A longitudinal prospective study was conducted on 90 young patients with TTH (37 with osmophobia, 53 without osmophobia). We evaluated whether osmophobia could predict the diagnosis transformation from TTH to migraine after a 3-year follow-up. Results and Discussion: In our cases the rate of diagnosis change was significantly greater in cases with osmophobia (62%) than in those without (23%). Osmophobia persisted at a 3-year follow-up …

Olfactory function in chronic rhinitis subtypes: Any differences?

2018

Introduction: Olfactory dysfunction is a common problem in rhinological disease, but it has been few evaluated among patients with different chronic rhinitis subtypes. The aim of this study was to assess olfactory function in patients with allergic rhinitis (AR), non-allergic rhinitis (NAR) and mixed rhinitis (MR). Materials and methods: A total of 122 patients with AR, NAR, and MR were included in the study. Sniffin' Sticks test was applied to all groups. The study groups were compared in terms of odor scores and an association between olfactory dysfunction and rhinitis grading, according to ARIA (Allergic Rhinitis and its Impact on Asthma) criteria, was also investigated. Results: A signi…
