Child mortality due to suffocation in Europe (1980-1995): a review of official data.

This report outlines the current status of the official statistical data available concerning mortality rates for suffocation in children <15 years of age, stratified according to sex and country in Europe, in the years 1980-1995. The data source is the WHO Mortality Database, which comprises deaths registered in national vital registration systems, with underlying cause of death as coded by the relevant national authority. To assess the impact of the problem of suffocation, the total potential years of life lost have been calculated. In addition, for Italy, and for the years 1999-2000, data related to deaths and hospitalizations for foreign body in the pharynx and larynx are presented. In Italy, in the years 1999-2000, the ratio between the number of hospitalizations and the mortality rates is approximately one death every 10 hospitalizations (x 100,000). The European mortality rate exceeds nearly one death per 100,000 persons. No evidence of any geographical pattern or cyclic trend emerged from the analysis of this official data.

Restoration of immune-mediated sensorineural hearing loss with sodium enoxaparin: a case report.

The aim of the study was to assess the efficacy of sodium enoxaparin in the treatment of autoimmune sensorineural hearing loss. A small number of patients with unilateral sensorineural hearing loss were selected and divided randomly into two numerically equal groups (groups A and B) if they fulfilled the inclusion criteria, i.e. being between 20 and 65 years of age, had been affected by systemic lupus erythematosus, had presented with a hearing loss of at least 30 dB of audibility threshold involving the medium frequencies (2000-4000 Hz), and had provided informed consent. Group A received sodium enoxaparin while group B (control) received placebo. In group A, all patients except one showed an improvement in hearing after sodium enoxaparin treatment. In group B, no patients showed an improvement in auditory function. In conclusion, our results underline the important role of sodium enoxaparin in the therapeutic management of this disease. The low number of patients suggests that further studies are required to confirm this initial data but this study suggests that sodium enoxaparin provides encouraging results in the treatment of autoimmune sensorineural hearing loss.

[Rationale of the use of COX-2 inhibitors in ENT pathologies].

Upper airways inflammations (rhinitis, rhinosinusitis, polyposis, otitis, pharyngitis, etc) the pathologies most commonly encountered in the daily clinical practice and they represent, because of the high sanitary costs, an important social problem. The Literature suggests that almost all the symptoms, which characterize upper airways inflammations, are induced by the production of prostaglandins by cyclooxigenase (COX); it is obvious the need of a therapeutic action at this level. The non steroidal anti-inflammatory drugs (NSAID) block the activity of both COX-1 and COX-2, whereas the selective inhibitors of COX-2 (the coxibs) act only on this isoform. Actually, the therapeutic effects of both NSAIDs and coxibs are due to their actions on COX-2, while the system toxicity of NSAIDs (gastrointestinal perforation or ulcer, reduction of glomerular filtration rate, prolongation of bleeding time) is ascribable to the inference of these drugs with the COX-1. In conclusion, a correct approach to ENT inflammations must implies the use of drugs efficacious against the typical symptoms of the inflammatory process (and specifically the symptom: pain), eventually joined with an appropriate antibiotic treatment; in this context, a selective inhibitor of COX-2 short course treatment offers the double advantage of managing the inflammation and avoiding damages to the gastric mucosa.

OSAS in children.

BACKGROUND: Major risk factors for obstructive sleep apnea syndrome (OSAS) in children include adenotonsillar hypertrophy, neuromuscular disease and syndromes such as Down's or Pierre-Robin's syndrome; there is currently no consensus concerning diagnosis and therapy. METHODS: The study analyses 40 children, aged 2 through 14 years, with macroscopic tonsillar hypertrophy (without recurrent tonsillitis but with OSAS) underwent adenotonsillectomy. Parents were invited to indicate the intensity of their children's symptomatology using a subjective evaluation scale, each patient underwent cephalometric analysis and polysomnography (PSG) before and after surgery. RESULTS: The subjective scale of symptoms passed from 3.01 before treatment to 0.42 after treatment, rhinomanometry, passed from 3.456 to 0.896 p after 1 month the surgical operation (P<0.05). The polysomnography showed a resolution of the number of obstructive events in 37 patients and a reduction in 3 patients and RDI index fell from a mean of 26.9-2.6 after therapy. The average of oxygen saturation changed from 79% before treatment to 95% after therapy. CONCLUSIONS: Adenotonsillectomy plays a major role in the treatment of OSAS.

Allergic rhinitis in Italy: epidemiology and definition of most commonly used diagnostic and therapeutic modalities.

Allergic rhinitis is classically defined as an IgE-mediated inflammation of nasal mucosa, characterised by nasal obstruction, rhinorrhea, sneezing and nasal itching. It is certainly a high-prevalence disease and an important social and medical problem in many industrialised Countries, affecting about 20% of the general population; moreover, it is diagnosed with increasing frequency, both in adults and children in many developing countries. In view of the high medical and social costs, a correct diagnostic approach to allergic rhinitis is a fundamental need for the otorhinolaryngologist, also considering the severe complications (asthma, rhinosinusitis, rhino-otitis, rhinosinusal polyposis) which could develop if this disease is not recognised and adequately treated in its early phases. In order to evaluate not only the present epidemiological characteristics of allergic rhinitis in Italy but also the most commonly used diagnostic and therapeutic approaches in the management of this disease, 145 Italian otorhinolaringologists were selected to take part in the investigation. Each was invited to complete a questionnaire, divided into 8 different sections, to be answered according to their daily clinical practice. The significance of the results has been compared with those of the international samples comprised in the ARIA Document and in the epidemiologic survey of the Standing Committee on Rhinology and Allergy of the International Federation of Otorhinolaryngological Societies. A critical analysis of these data leads to some interesting epidemiological and therapeutic considerations.

High frequency surgery in the treatment of turbinate hypertrophy: 11 years' experience.

For over a century, surgical management of lower turbinate hypertrophy has given rise to much discussion. Aim of the present investigation was to establish, by means of the analysis of a large patient population, the efficacy and reproducibility of high frequency surgery in the treatment of this condition. A total of 1689 non-allergic patients with nasal obstruction, presenting hypertrophy of the lower turbinates, were submitted, under local anaesthesia, to turbinates decongestion using a high frequency instrumental unit with a bipolar terminal electrode. Efficacy of the procedure was evaluated on the basis of objective examination, results of questionnaires, active anterior rhinomanometry and mucociliar transport time. Results revealed a reduction of hypertrophy, an improvement in symptoms, a reduction in nasal resistances and an improvement of mucociliar transport time. The large patient population, low post-operative complication rate and the good patient compliance, due also to the fact that no haemostatic procedure is necessary, would suggest that this method is particularly valid, effective and safe for the treatment of hypertrophy of the lower turbinates.

[Specific nasal provocative test in allergic rhinitis diagnosis: reliability and standardization].

Specific vasomotorial rhinopathy, or allergic rhinitis is to be seen as a systemic pathology characterized by a condition of hyperactivity, the target organ of which is the nose. Particular attention, among the diagnostic tests, should be reserved to the specific nasal provocative test (sNPT), which has been part of the clinical routine for years but has nonetheless failed to achieve a suitable level of standardization. With this intent, we have devoted the present work to the assay of several phlogosis mediators (tryptase, specific IgE and ECP) before and after performing the sNPT. We have studied 20 patients affected by allergic rhinitis, aged between 13 and 61, with single or multiple allergen sensitivities, but in any case with a predominant sensitization, who underwent sNPT between October 2000 and July 2001. In every patients we performed ECP, tryptase and specific IgE assay via direct incubation in the nasal mucosa, before and after specific nasal provocation. The results of the sNPT (rhinomanometry and symptoms score) were compared with the variations in the phlogosis mediators assayed at nasal level. On the basis of the variations in the rhinomanometric resistance and symptoms score, the sNPT was positive in 10 patients (50%). Tryptase and specific IgE increased to a statistically significant degree (respectively, p = 0.01 and p < 0.05) in all of the patients; the ECP variations, instead, were not significant (p > 0.05). Overall, the simultaneous assay of ECP, tryptase and specific IgE, increasing the sensibility of the sNPT, enabled a positive result to be ascertained in 60% of the subjects examined. The method is furthermore based on the principle of local reactivity in that it assays the phlogosis mediators not at systemic level, but directly in the target organ, showing itself to be more specific than level I and II tests.

Do tryptase, ECP and specific IgE measurement by nasal incubation increase the specific nasal provocation test sensitivity?

The specific Nasal Provocation Test (sNPT) is a third level diagnostic tool. Fitted to reproduce natural exposure condition to pick the responsible allergen for nasal symptoms out, it is applied when prick test and RAST responses are doubtful. SNPT results have been evaluated measuring nasal resistance (anterior rhinomanometry) and nasal symptoms (clinical score), reaching 50% of sensitivity. This study focused on the determination of allergic response markers, triggered by nasal challenge: tryptase levels in the nose, specific IgE and ECP (Eosinophil Cationic Protein). The aim was to increase sNPT sensitivity. Twenty patients suffering from allergic rhinitis and 16 age-matched-nonallergic subjects were enrolled in the study. Tryptase, specific IgE and ECP were determined in nasal mucosa applying a new method, based on in situ incubation, before and after sNPT. The latter was performed following a standardized method. Tryptase levels increased in 13 patients (65%), were unchanged in four patients (20%), and slightly decreased in three patients (15%). The increase recorded was significant in mite allergic patients (p=0.005), but not significant (p> 0.05) in pollen allergic patients. ECP values increased in 13 patients (65%), were unchanged in two patients (10%), and highly decreased in five patients (25%). ECP increase was not significant (p> 0.05). Specific IgE levels increased in seven patients (35%), were unchanged in 11 patients (55%) and decreased in two patients (10%). The IgE increase was significant in pollen-allergic patients (p<0.05), while it was not significant in mite-allergic patients (p>0.05). Tryptase, ECP, and specific IgE were not detected in the control group. The data obtained showed a positive sNPT response in 12 patients (60%). Comparing our results with those derived from classical-parameter employment, we gathered an improvement of 10%. On the basis of the usual parameters, in fact, we recorded 50% positivity, while the use of mediators provided an additional 10% improvement in sNPT sensitivity: taking together the usual parameters and nasal allergic mediators values, we reached an sNPT over-all sensitivity of 85%.
