Nasal hypersensitivity in purulent middle ear effusion

The existence of a physiopathologic connection between nose and middle ear is widely accepted so that chronic purulent middle ear effusion (CPMEE) could be expected to be usually associated with nasal chronic disease or impaired function. Nevertheless such association is less frequently observed in clinical practice than one could expect, possibly because of inadequate nasal function evaluation. Thirty-five patients affected by CPMEE were included in this study in order to assess the incidence of nasal disorders. E.N.T. clinical history was obtained and E.N.T. physical examination, nasal endoscopy by fiberoptics, anterior rhinorheomanometry, non-specific nasal provocation test with histamine, mucoliary transport test, and allergic skin tests were performed. In the clinical history assessment 26 patients were affected by chronic rhinopathies, 16 by chronic pharyngitis, and 20 by frequent headache. At rhinoscopy we registered nasal septum deviation in 24 cases and mean and inferior turbinates hypertrophy in 31 cases. CPMEE and nasal septum deviation or turbinates hypertrophy were more frequently omolateral (p < .001 and p < .05, respectively). Total nasal resistance was 0.99 ± 0.49; it was abnormally high in 11 subjects bilaterally and in 4 subjects monolaterally and increased significantly in 32 patients following nasal provocation test. Mucociliary transport time was longer in CPMEE subjects than in 10 healthy subjects (18 ± 5 vs 13 ± 4 min; p < .05). Finally 10 patients presented positive skin tests. On the whole, 96% of non allergic patients included in this study showed signs of non-specific nasal hypersensitivity which could theoretically cause purulent middle ear effusion to chronicize. Indeed recurrent histamine release in response to specific and/or aspecific stimuli could cause the obstruction of the Eustachian tube and consequently inadequate middle ear ventilation

Taste and olfaction in middle ear surgery

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 patholog

Nasal histamine responses in nonallergic rhinitis with eosinophilic syndrome

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

Pathological and cytological changes of the nasal mucosa in acute rhinosinusitis: the role of hyaluronic acid as supportive therapy

OBJECTIVE: The aim of this study was to evaluate the reparative role of hyaluronic acid in acute rhinosinusitis (ARS). PATIENTS AND METHODS: 48 patients affected by ARS were submitted to nasal endoscopy, nasal cytology, mucociliary transport evaluation (MCTt) and visual analogue scale questionnaire (VAS) at T0, after 14-18 days (T1) and after 30-35 days (T2). The patients were randomized into two groups, A and B, and received Levofloxacin and Prednisone. Moreover, using a nebulizer ampoule for nasal douche, Group A received high molecular weight Sodium Hyaluronate (3%) plus saline solution (NaCl 0.9%) twice a day for 30 days; Group B received saline solution twice a day for 30 days. RESULTS: At T0 only the VAS score showed differences regarding nasal discharge and post-nasal drip. At T1, in Group A MCTt and the number of bacteria were significantly lower than in Group B. The VAS score showed improvement in Group A. At T2 in Group A, MCTt and number of neutrophils were significantly lower than in Group B. The VAS score showed statistically significant differences between the two groups regarding nasal discharge. CONCLUSIONS: In ARS patients sodium hyaluronate plus saline solution significantly improved symptoms, MCT time and reduced neutrophil count on nasal cytology

Clinic manifestations in granulomatosis with polyangiitis

Granulomatosis with polyangiitis (GPA), formerly Wegener's granulomatosis (WG), is an uncommon immunologically mediated systemic small-vessel vasculitis that is pathologically characterised by an inflammatory reaction pattern (necrosis, granulomatous inflammation and vasculitis) that occurs in the upper and lower respiratory tracts and kidneys. Although the aetiology of GPA remains largely unknown, it is believed to be autoimmune in origin and triggered by environmental events on a background of genetic susceptibility.In Europe, the prevalence of GPA is five cases per 100,000 population, with greater incidence in Northern Europe. GPA can occur in all racial groups but predominantly affects Caucasians. Both sexes are affected equally. GPA affects a wide age range (age range, 8-99 years).Granulomatosis with polyangiitis is characterised by necrotising granulomatous lesions of the respiratory tract, vasculitis and glomerulonephritis. Classically, the acronym ELK is used to describe the clinical involvement of the ear, nose and throat (ENT); lungs; and kidneys. Because the upper respiratory tract is involved in 70-100% of cases of GPA, classic otorhinolaryngologic symptoms may be the first clinical manifestation of disease. The nasal cavity and the paranasal sinuses are the most common sites of involvement in the head and neck area (85-100%), whereas otological disease is found in approximately 35% (range, 19-61%) of cases.Diagnosis of GPA is achieved through clinical assessment, serological tests for anti-neutrophil cytoplasmic antibodies (ANCA) and histological analysis. The 10-year survival rate is estimated to be 40% when the kidneys are involved and 60-70% when there is no kidney involvement.The standard therapy for GPA is a combination of glucocorticoids and cyclophosphamide. In young patients, cyclophosphamide should be switched to azathioprine in the maintenance phase.A multidisciplinary approach, involving otorhinolaryngologists, oral and maxillofacial surgeons, oral physicians, rheumatologists, renal and respiratory physicians, and ophthalmologists, is necessary for the diagnosis and therapeutic treatment of GPA. ENT physicians have a determining role in recognising the early onset of the disease and starting an appropriate therapy

Research of non-specific hyperreactivity of upper airways in subjects with gastro-esophageal reflux (G.E.R.): Preliminary reports

An association between asthma and gastro-esophageal reflux (GER) is well recognized but the underlying mechanism is still unclear. The authors suggest that could exist an association between GER and upper airways hyperreactivity and this association could represents the mechanism underlying the lower esophageal sphincter releasing, that determine the reflux. In fact they suppose that, the noxious injury of acid reflux follows a course that could be: pharynx → larynx → bronchi → 1/3 inferior of the esophagus → reflux. From these presuppositions the authors carried out a study on the possible relationship between GER and non-specific hyperreactivity of upper airways on 14 subjects, divided in 2 groups: 10 subjects with functional GER, 4 subjects suffering from GER caused by hiatus hernia as control group. All patients had a thorough medical history, ENT examination with rigid and flexible endoscope, anterior Rhinomanometry (RRM), skin-test for inhalant and alimentary allergens, RAST, audiometric exam, non-specific nasal provocation test (NSNPT) with histamine, using as control the number of sneezes. From a through analysis of objective examination and from the results of the NSNPT with histamine resulted that all subjects with functional GER were rhinopathics. In all tests both in vivo (Skin-test) and in vitro (RAST) for the most common allergens (pollens-inhalant-mycophites-alimentary) the results were negative. The authors also found an involvement of paranasal sinuses that raised: 91% in the patients with recurrents phlogosis due to non specific nasal hyperreactivity; 40.9% in the allergic subjects (20% in the Graminacee +; 32% in the Parietaria O. +; 76% in the Dermatophagoides Pt. +; others 4%); 100% in the ASA-intollerance subjects. The NSNSPT with histamine showed in the group with functional GER a hyperreactivity with sneezes in 6/10 subjects, and 1/4 subjects of the group with GER with hiatus hernia. The RRM variations showed an unilateral nasal hyperreactivity in 6/10, bilateral in 3/10 subjects of the group with functional GER. In the group with GER with hiatus hernia only 1/4 subject showed reliable unilateral RRM variation. From the analysis of data resulted that subjects with functional GER showed a completely involvement of the upper airways and not only of the pharynx and larynx, caused by non specific hyperreactivity at the NSNPT with histamine, associated with a chronic pathology
