Laryngopharyngeal reflux management in clinical practice.

Laryngopharyngeal reflux (LPR) is an inflammatory reaction of the mucosa of the pharynx, larynx, and other associated upper respiratory organs, caused by a reflux of stomach contents outside the esophagus. LPR is considered a relatively new clinical entity with a vast number of clinical manifestations that are sometimes treated empirically and without a correct diagnosis. Alginate is a reasonable therapeutic option as a first-line or add-on option. A survey included 35 Italian otorhinolaryngologists. The survey considered ten practical queries. LPR is a common disease in clinical practice. History and fiber-optic endoscopy constitute the main diagnostic tools. Alginates represent a frequent medication to treat LPR both as first-line and add-on. The mean effectiveness rate is 44% for first-line choice and 76% for the add-on. In conclusion, the current survey provided exciting information about the management of LPR in clinical practice.

Simplified local nasal immunotherapy in mite dust allergic rhinitis.

The present work aimed at evaluating the efficacy and tolerance of an alternative schedule of local nasal immunotherapy for the treatment of mite dust allergic rhinitis. The authors suggest the nasal administration of the maximum tolerated dosage chosen on the basis of nasal provocation test threshold, comparing allergen extracts in micronized powder and watery solution. Forty-five patients (25 men and 20 women), aged 18 to 66 years, affected by allergic rhinitis to Dermatophagoides (Dpt) were selected and treated either by local immunotherapy in watery solution (15) or in powder form (15) or by parenteral specific hyposensitizing treatment (15). Before and one year after the beginning of the study, the clinical diaries and the total and specific IgE variation were evaluated. The monthly symptoms and drugs use are comparable among the three treatment groups. No significant difference was found, with the exception of local symptomatology, which improved more in patients undergoing local immunotherapy (p > 0.05); and oral antihistamines use, which was lower in patients treated with the watery solution (p < 0.05). Thus, local simplified hyposensitizing treatment is able to combine the absence of symptomatological worsening with the decrease of both local and systemic drugs use. The advantages of the LNIT protocol proposed herein are as follows: simplified schedule for self-administration; improved patient compliance; reduction of local side effects; clinical efficacy comparable with subcutaneous specific immunotherapy.

Amoxicillin/clavulanate in chronic rhinosinusitis: tissue and serum distribution.

UNLABELLED: Amoxicillin/clavulanate in chronic rhinosinusitis: tissue and serum distribution. OBJECTIVE: The aim of the present study is to determine the concentrations of coamoxiclav in the sinusal mucosa of patients undergoing surgery for chronic sinusitis in comparison to serum levels after single oral administration. METHODOLOGY: 24 patients affected by chronic sinusitis, undergoing sinus surgery, were divided into three groups receiving an oral dose of 1 g of coamoxiclav (875 mg amoxicillin, 125 g of clavulanic acid, 7:1 ratio) at 2 h (first group), 4 h (second group) and 6 h (third group) before surgery. The mean concentration of amoxicillin and clavulanic acid were determined biologically in serum and in tissues. RESULTS: The highest concentrations of coamoxiclav both in serum and tissues were observed in the group which received the antibiotic 2 hours before surgery. However the tissue levels of both amoxicillin and clavulanic acid in the time period within 2-6 h after administration were higher than the Minimum Inhibitory Concentration (MIC) for the most frequent causative pathogens of sinus bacterial infections. CONCLUSIONS: Since penicillins need to maintain concentrations above the MIC for at least 40 to 60% of the interval time between administrations to be potentially effective, the Authors concluded that since both amoxicillin and clavulanic acid spread well in the ENT tissues, 1 g twice a day of the combination seems to be clinically effective even in patients suffering from acute episodes of chronic rhinosinusitis.

Spontaneous onset of CSF otorrhea from a facial canal fistula in an adult: case report.

The purpose of this report is to describe a 64-year-old woman who presented an 8 month history of recurrent spontaneous cerebrospinal fluid leakage into the left middle ear. High resolution computed tomography and computed tomography cisternography showed only a mild protrusion of the tympanic segment of the left facial canal into the ipsilateral middle ear but no definitive fistula. At surgical exploration, cerebrospinal fluid leakage resulted from a fistula in the tympanic segment of the left facial canal. In conclusion, in the adult patient reported herein, the fistula leading to spontaneous CSF otorrhea was identified definitely only intraoperatively. Furthermore, although there were no signs or symptoms of facial nerve dysfunction, it was located in a rare site such as the second segment of the facial canal. When the clinical history, physical examination, and laboratory analysis are strongly suggestive for spontaneous CSF otorrhea, surgical exploration is mandatory even if neuroimaging evaluation is negative or questionable.

Efficacy of inhalation form of furosemide to prevent postsurgical relapses of rhinosinusal polyposis.

The aim of the work is to demonstrate the efficacy of furosemide to prevent relapses of rhinosinusal polyps after surgical treatment. Two groups of people with rhinosinusal polyposis were enrolled: the study group consisted of 64 patients and the control group of 40 subjects. After surgical treatment, the study group started the therapy with topical furosemide; the control group had no treatment administered after the operation. Six years after the operation only 4 cases of relapse were noticed in the study group (10%), while there were 12 relapses, 4 slight (6.4%) and 8 severe (20%), in the control group. In conclusion, furosemide could represent a valid therapeutic aid in the prevention of nasosinusal polyps.

The role of rhinomanometry, acoustic rhinometry, and mucociliary transport time in the assessment of nasal patency.

We conducted a study of 60 patients with different nasal pathologies who complained of nasal obstruction. Our goal was to evaluate the reliability of rhinomanometry, acoustic rhinometry, and the measurement of mucociliary transport time in helping make the diagnosis of nasal pathologies. We also sought to discover whether there is a correlation between the findings of these objective tests and the results of patients' own subjective assessments of nasal obstruction. We found that acoustic rhinometry was more specific and more sensitive than rhinomanometry in diagnosing rhinopathies in patients with structural anomalies. Symptom scores as rated by patients on the visual analog scale frequently did not correlate with objective measures, as patients often overestimated the severity of their obstruction. However, for a few patients, there was a correlation between symptom scores and mucociliary transport times.

A new method for endoscopic evaluation in rhinology: videocapture.

The aim of the study is to analyze a new method for the elaboration of endoscopic images of the nasal cavity called "videocapture" and to compare the data from this technique with the ones obtained with anterior active rhinomanometry. Videocapture is based on a software program able to process endoscopic images, to file them and to measure perimeter and area of the structures inside the images recorded. We enrolled 27 patients with inferior turbinate hypertrophy and we performed, before and after nasal decongestion test, anterior active rhinomanometry, acoustic rhinometry, videocapture to compare the results obtained with these different techniques. The results we got confirm in a statistically significant way, the reliability of videocapture and its easy way of application.

Monitoring methods of nasal pathology.

The importance of correct clinical and therapeutic monitoring of allergic rhinitis is understandable in the light of the social and economic impact of this pathology: its prevalence is over 10% of the total population all over the world. For the evaluation of the local nasal pathology we include: (1) anterior rhinoscopy, (2) active anterior rhinomanometry, (3) positioned acoustic rhinometry, (4) determination of mucociliary transport time, (5) specific nasal provocation test. Active anterior rhinomanometry allows reliable assessment of the nasal respiratory function, acoustic rhinometry shows the geometry of nasal cavity, mucociliary transport time is an indicator of the mucosa eutrophism. In our experience, the specific nasal provocation test is one of the most important tests in this field. It is more sensitive than the skin test and the radioallergosorbent test (RAST) in the asymptomatic phase and it is able to show organ allergies. In this study we review the importance of this test and the methodology we commonly use.

Nasal allergy and atmospheric pollution.

Among the effects that pollution of the air causes on human health, irritation of the exposed mucosa is the earliest and the most obvious one. Pollutants damage the anatomical and functional integrity of the primary airways, in particular they cause alteration of the mucociliary system. The mucosa undergoing continuous aggression by an aerosol loaded with pollutants assumes the characteristics of a tissue with chronic inflammatory processes with dysepithelialised areas that could be an easy entrance for airborne allergens. The loss of integrity of epithelial lining, the interference with the repulsion of extraneous particles trapped in the mucus, the infiltration of the inflammatory cells and lymphocytes called into action by the phlogistic reaction multiply the occasion of meeting between environmental allergens and the immunological system of the host and basically of setting in motion the process of sensitisation. So there is a strict relationship between nasal allergy and pollution, that should not be ignored: allergy is the cause of considerable disturbances interfering with study, work and social activity and can lead to local and distal complications.
