ABSTRACT

OBJECTIVE: To evaluate olfactory function and clinical-neurological characteristics in a group of patients with mild head trauma. METHODS: A total of 352 patients with MTBI underwent olfactory function evaluation. The site of head trauma, loss of consciousness <20 min, memory loss, subjective presence or absence of olfaction and other clinical, neurological and radiological aspects were evaluated and compared with the olfactory dysfunction. RESULTS: A total of 33.5% patients enrolled in the study had an olfactory dysfunction. Eighty-seven percent of the patients had a diagnosis of anosmia whereas 13% had a diagnosis of hyposmia. Statistical analysis did not show a correlation between radiologically detected head lesions and different types of olfactory dysfunction (p > 0.05). Besides, no difference between head lesion site and different olfactory dysfunction was reported (p = 0.5). Regarding olfactory sub-tests a low detection threshold was present in these patients. CONCLUSION: The possibility of olfactory dysfunction should be considered in any case of MTBI appears differently than expected, a minor head injury causes anosmia much more frequently than hyposmia.

ABSTRACT

Acute rhinosinusitis (ARS) is defined as an inflammation of the mucosa of the nose and paranasal sinuses and affects 1-5 % of general population in Europe. Sinonasal diseases represent the main cause of smell alterations in adult patients and lead to mucosal congestion, increased quantity and density of secretions and altered mucociliary transport. For this reason the odorous molecules contained in the inspired air, cannot interact with the olfactory epithelium. Medical therapy of ARS has to reduce the severity and duration of symptoms and prevent complications. Recent studies have shown that Sodium hyaluronate modulate inflammation and has a reparative effect on the nasal mucosa. 48 patients affected by acute rhinosinusitis proven by CT scan, were enrolled. They were submitted to nasal endoscopy, olfactometric and mucociliary transport evaluation (MCTt), Visual Analogue Scale Questionnaire (VAS) at T0, after 14-18 days (T1) and after 30-35 days (T2). The patients were randomized into two treatment groups, A and B, and were treated for 30 days; each group was composed of 24 subjects. All patients received Levofloxacin (500 mg for 10 days) and Prednisone (50 mg for 8 days, 25 mg for 4 days and 12, 5 mg for 4 days). Moreover, Group A received twice a day for 30 days high molecular weight Sodium Hyaluronate (3 %) plus saline solution (3 mL sodium chloride-NaCl-0.9 %) using a nebulizer ampoule for nasal douche. Group B received twice a day for 30 days saline solution (6 mL sodium chloride-NaCl-0.9 %) using a nebulizer ampoule for nasal douche. At T1 Group A shown lower values in MCTt and threshold score was significantly higher than in Group B. VAS showed statistically significant differences between the two groups, in particular for smell, nasal obstruction and for nasal discharge. At T2 Group A MCTt was significantly lower than in Group B; odour threshold improved in both groups but in Group A was still significantly higher than in Group B. No statistical differences between two groups regarding odour discrimination and odour identification were confirmed at T1 and T2. VASy score showed statistically significant differences between the two groups only for nasal discharge.

ABSTRACT

OBJECTIVE: The reported range of involvement of human papillomavirus (HPV) in laryngeal squamous cell carcinoma (SCC) is wide because of the methods used to detect HPV. DATA SOURCES: A computerized Medline study was carried out using the following as key words: "Papillomavirus Infections"[Mesh] and "Laryngeal Neoplasms"[Mesh]. MATERIALS AND METHODS: Studies that were included were written in English and reported results of HPV DNA with RNA in laryngeal SCC. RESULTS: There were six reported HPV mRNA extraction. Among these studies, Lewis et al reported that out of the 31 cases analyzed, only 2 were HPV DNA+ and of these only 1 was mRNA HPV+ (3%). Halec et al reported 102 cases of which 32 were HPV DNA+ cases and of which only 6 were mRNA+ (5%). Chernock et al reported 76 cases of which 13 were HPV DNA+ cases and of which 4 were mRNA+ (5%). Masand et al reported 8 cases of which 1 was HPV DNA+ case and none was mRNA+. Gheit et al reported 43 cases of which 4 were HPV DNA+ cases and of which 2 were mRNA+ (4%). Castellsagné et al reported 1042 cases of which 59 were HPV DNA+ case and of which 51 were mRNA+ (4.8%) CONCLUSIONS: When determining the role of HPV in laryngeal SCC, evidence of HPV DNA warrants further examination for E6/E7 mRNA as simple assays such as p16 are nonspecific in laryngeal SCC. Further studies of HPV and its role in laryngeal SCC are warranted.

ABSTRACT

BACKGROUND: Nonallergic rhinitis with eosinophilic syndrome (NARES) is persistent, without atopy, but with ≥25% nasal eosinophilia. Hypereosinophilia seems to contribute to nasal mucosa dysfunction. OBJECTIVES: This analytical case-control study aimed at assessing the presence and severity of nonspecific nasal hyperactivity and at finding out whether eosinophilia may be correlated with the respiratory and mucociliary clearance functions. MATERIALS: The symptom score was assessed in 38 patients and 15 controls whose nasal smear was also tested for eosinophils and mucociliary transport (MCT). Nonspecific nasal provocation tests (NSNPT) with histamine were also carried out, and total nasal resistance (TNR) was determined. RESULTS: The symptom score of NARES after NSNPT were not significantly different from the control group, and there was poor or no correlation among the single symptoms and the differences studied for every nasal reactivity class. This correlation improved when using the composite symptom score. The most severe eosinophilia was observed in high reactivity groups, and it was correlated with an increase in TNR. MCT worsened as eosinophilia and nasal reactivity increased. Unlike controls, a significant correlation was observed between the increase in MCT and TNR. CONCLUSIONS: In NARES, nonspecific nasal hyperreactivity is the result of epithelial damage produced by eosinophilic inflammation, which causes MCT slow down, an increase in TNR, and nasal reactivity classes, with possible impact on classification, prognosis, and treatment control.

ABSTRACT

OBJECTIVE: The aim of this study was to assess pre- and postoperative taste ability in patients undergoing middle ear surgery for otosclerosis or chronic otitis media. Olfactory function was also evaluated to rule out taste deficits due to concomitant nasal pathology. METHODS: All patients underwent ear, nose, and throat examination, otomicroscopy, nasal endoscopy, anterior rhinomanometry, taste testing, and olfactory testing. Patients were evaluated at 1 to 5 days preoperatively (T0), and at 1 (T1), 6 (T6), and 12 (T12) months postoperatively. RESULTS: Both groups of patients experienced worsening of the mean taste threshold postoperatively. This phenomenon was more serious in poststapedotomy patients. Follow-up showed progressive improvement in both groups. All values of olfactory testing were within the normal range for otosclerosis patients. Patients with chronic otitis media showed variable postoperative findings. CONCLUSION: Chorda tympani function can be negatively affected by middle ear surgery. Deficits may be more marked in stapedotomy patients than in those undergoing tympanoplasty. Postoperative recovery of taste is satisfactory, although with different timelines for the 2 types of pathology.

ABSTRACT

OBJECTIVE: The purpose of this study was to assess olfactory-gustatory function impairment in patients with eating disorders. METHODS: Nineteen patients with a diagnosis of bulimia nervosa, 18 patients with a diagnosis of anorexia nervosa and a control sample of 19 healthy subjects were recruited from the day hospital service of the Complex Operative Unit for Alimentary Conduct Disorders of the Policlinico Umberto I in Rome. Evaluation of olfactory and gustatory functions was performed on patients through the 'Sniffin' Sticks' method in order to assess the olfactory threshold, the capacity for discriminating and identifying olfactory stimuli, and the overall olfactory function, and through the 'taste strip' kit method in order to assess the gustatory function. The results were processed statistically to assess differences between patients with anorexia nervosa, patients with bulimia nervosa and healthy controls. RESULTS: The two groups of patients with bulimia nervosa and anorexia nervosa showed a poorer olfactory and gustatory function compared with the healthy controls; discrimination of olfactory stimuli and overall olfactory function were reduced in both samples, as well as the overall gustatory function and the perception of bitter stimuli, whereas olfactory threshold was altered only in patients with bulimia nervosa. In both samples, scores for olfactory function fell within the range of hyposmia. DISCUSSION: Our data suggest that patients with eating disorders have an altered perception of olfactory and gustatory stimuli. The alterations observed are worth further investigation.

ABSTRACT

OBJECTIVE: To identify the presence of B lymphocytes in the rhinoscleroma granulomas as a possible precursor of plasma cells, whose presence has always been described but whose role is still unclear. STUDY DESIGN: Case series with chart review. SETTING: Sapienza University of Rome. METHODS: The study was carried out on 6 patients (3 women, 3 men). The following parameters were examined for each patient: clinical manifestations, number of leukocytes, lymphocytes and lymphocyte subsets (CD3+, CD4+, CD8+, and CD19+) in blood samples, time from the onset of symptoms, biopsies, and expression of CD3, CD4, CD8, and CD20 antigens in tissue samples with immunohistochemical techniques. RESULTS: In this study, the values of CD3+, CD4+, and CD8+ T lymphocyte subsets in venous peripheral blood are in line with previously reported data, whereas CD19+ lymphocyte cells tended to show an ambiguous behavioral pattern. In tissue samples, approximately one-third of the T lymphocyte population showed a CD3+/CD8+ immunophenotype (cytotoxic/suppressor), and two-thirds of the T lymphocytes expressed a CD3+/CD4+ immunophenotype (helper/inducer). The authors also identified an unexpected large amount of CD20+ non-plasmacellular B cells in addition to the plasma cells usually detected in rhinoscleroma biopsies. CONCLUSIONS: This study demonstrates the presence of B lymphocytes in rhinoscleroma tissue. It is presumable that the mature B cells activated by antigenic stimulation of Klebsiella rhinoscleromatis are the precursors of the plasma cells typically found in the granuloma of rhinoscleroma.

ABSTRACT

PURPOSE: This study aimed at assessing the most common aetiological factors causing total or partial olfactory deficit and the statistical analysis of some clinical aspects. MATERIALS AND METHODS: 243 patients reporting alfactory dysfunction were enrolled in this STUDY: A case history was drawn up for each patient, and all of them underwent otolaryngology objective examination, including nasal endoscopy, paranasal sinuses CT-scan, and Utrecht method (GITU) based smell indentification test. RESULTS: Upper respiratory viral infections (40.2%), ceanial-facial traumas (39.3%), and rhinosinusal pathologies (6.3%) were the main aetiopathological factors indentified. A relevant number of case were recorded with unknown aetiology (14.2%). In 2 cases, olfactory dysfunction was due to neurological diseases, in 1 case it was due to intoxication and, in another case, it was congenital. The correlation between aetiology, gender, age, symptoms duration and deficit severity was studied. CONCLUSIONS: many different aetiological factors caused the loss or weakening of the sense of smell. They mainly affected olfactory neurosensorial structures and odorant conduction. However, there were many cases of unknown aetiology. Women, over 40 in particular, were the most affected. Anosmia and severe hyposmia were mainly correlated with traumas and viral pathologies.
