The music-related quality of life: Italian validation of MuRQoL into MUSQUAV questionnaire and preliminary data from a cohort of postlingually deafened cochlear implant users.

PURPOSE: Cochlear implant (CI) users do not receive much of the auditory information necessary for an accurate perception of music. This usually entails a dissatisfaction with the music they hear, so that their quality of life may potentially be affected. The main aim of this paper was to translate and validate into Italian an instrument to evaluate these aspects-The Music-Related Quality of Life Questionnaire (MuRQoL)-to help the work of clinicians and therapists. METHODS: The translation of the MuRQoL into "Questionario Musica e Qualità della Vita" (MUSQUAV) was done according to the international guidelines. The translated questionnaire was administered to normal hearing (NH) and CI users adults. Exploratory factor analysis, confirmatory factor analysis and known group method were used to confirm construct validity and applicability of MUSQUAV. RESULTS: We retrieved 225 results. The MUSQUAV questionnaire was acceptable according to the goodness-of-fit indices. The correlation between the items, evaluated using Cronbach's α coefficient, indicates a good internal consistency (> 0.80). The non-parametric Mann-Whitney test showed significant differences in the distinct populations tested. CONCLUSIONS: The MUSQUAV questionnaire is a valid, low-cost and rapid instrument for professional workers in the audiological field, especially useful in the assessment of the patients' perception and musical engagement.

Nasal function before and after rapid maxillary expansion in children: A randomized, prospective, controlled study.

OBJECTIVES: Children can well detect and respond to odours in order to have information about food and environment. Rapid Maxillary Expansion seems to improve dental and skeletal crossbite and increase nasal patency correcting oral respiration in children. A previous pilot study suggested that Rapid Maxillary Expansion may lead to improved N-Butanol olfactory thresholds, and peak nasal inspiratory flow values (PNIF). The aim of the present study was to prospectively evaluate olfactory threshold, nasal flows and nasal resistances in children aged from 6 to 11 years before and after Rapid Maxillary Expansion, comparing treated children with a control group of similar age, growth stage (prepubertal) and transversal skeletal deficiency. METHODS: N-butanol olfactory thresholds, anterior active rhinomanometry (AAR) and PNIF were measured in 11 children (6-11 years) before (T0), immediately and 6 months after Rapid Maxillary Expansion application (T1 and T2 respectively), and in a control group of 11 children (6-11 years) whose members remained under observation for the period of the study. RESULTS: Considering the study group, PNIF values improved at T1 respect to the T0 values (p = 0.003), while T2 values were significantly higher than T0 ones (p = 0.0002). N-Butanol Olfactory Threshold significantly improved at each control (p = 0.01, p = 0,01 and p = 0.0003, for T1 vs T0, T2 vs T1, T2 vs T0 respectively). No differences on AAR values were found during the six months follow-up in this group. Considering the control group, no significant differences were found for any of the considered variables during the time of the study. Comparing the two groups, there was a significant increase of PNIF values in the study group compared to the control group (p = 0.003) at T1, which was even more evident six months after Rapid Maxillary Expansion (p = 0.0005). This improvement was not shown by AAR values. N-Butanol Olfactory Threshold showed a significant improvement at T2 respect to T1 (p = 0.002) and T0 (p = 0.0005). CONCLUSION: Rapid Maxillary Expansion seems to significantly improve the respiratory capacity of treated patients, at least in terms of PNIF, and their olfactory function, measured by N-Butanol Olfactory Threshold Test. Further studies should be performed to evaluate if also changes in nasal resistances, measured by AAR, could occur, maybe considering a larger group of subjects and possibly using 4-phase rhinomanometry in order to evaluate the effective resistances during the entire breath.

Idiopathic benign paroxysmal vertigo in children, a migraine precursor.

Vertigo and dizziness are common conditions in the adult population that can be rarely seen during childhood; only a few articles describing vertigo in children can be found in literature. Although many causes of vertigo in adulthood occur also in childhood, their frequency may be different. A typical example is benign paroxysmal positional vertigo, the most common peripheral vestibular disorder in adults, which occurs quite uncommonly in children. Furthermore, many common diseases causing vertigo in children may be unique for this population, such as benign paroxysmal vertigo (BPV) of childhood. At present, BPV is defined as a migraine's equivalent, a precursor of migraine or a periodic syndrome of childhood. The International Headache Society also studied this form of vertigo and included the Benign Paroxysmal Vertigo in section 1.3.3. of the International Classification of Headaches (ICHD-2). The present review analyzes recent patho-physiological and clinical evidences regarding idiopathic BPV in children.

Ear, nose and throat manifestation of viral systemic infections in pediatric patients.

OBJECTIVE/METHODS: An exhaustive review of literature was performed to investigate available data and evidences regarding pediatric otolaryngologic manifestations of viral systemic infections. RESULTS/CONCLUSIONS: Modern otolaryngologists should be familiar with viral systemic infections since many have head and neck manifestations. Cooperation between otolaryngologist, paediatrician and virologist can be considered and excellent tool in diagnosis and treatment of these diseases in particular when complications occur.

Anosmia associated with hearing loss and benign positional vertigo after head trauma.

It is well known that head trauma may cause hearing loss, which can be either conductive or sensorineural. Benign paroxysmal positional vertigo and olfactory dysfunction due to head trauma are also well known. The association between sensorineural hearing loss and anosmia, following head trauma, is extremely rare. Two rare cases of post-traumatic occurrence of hearing loss, olfactory dysfunction and benign positional vertigo are reported and the pathophysiology of the association between sensorineural hearing loss, anosmia and benign paroxysmal positional vertigo, after head injury, are briefly discussed. ENT specialists should, in the authors' opinion, be aware of the possible association between anosmia, sensorineural hearing loss and benign paroxysmal positional vertigo after head injury, even in the absence of skull fracture.

Nuclear expression of maspin is associated with a lower recurrence rate and a longer disease-free interval after surgery for squamous cell carcinoma of the larynx.

AIMS: Maspin, a protein belonging to the serpin superfamily, is the product of a tumour suppressor gene. Tissue distribution studies have shown maspin expression in normal mammary epithelial cells, in the placenta, prostate, thymus, testis, oral cavity, small intestine, skin, and cornea. Maspin is expressed but down-regulated in human breast, prostatic, and colonic cancers but apparently up-regulated in pancreatic, ovarian, and gastric cancers. Only two studies concerning maspin expression in head and neck carcinomas are available. The present study is the first attempt to determine maspin expression in laryngeal carcinoma. METHODS AND RESULTS: Maspin expression was evaluated in 21 cases of laryngeal carcinoma consecutively treated with an exclusively surgical approach with a follow-up period longer than 24 months. The expression of p53, p27 and MIB-1 was also studied. Two patterns of distribution of maspin in laryngeal neoplastic cells were found. Cytoplasmic expression of maspin was identified in 47.6% of the cases. Nuclear maspin positivity was determined in 47.6% of the cases. A statistically significant difference in nuclear maspin expression between the group of patients without carcinoma recurrence and the group with evidence of recurrence was demonstrated (P = 0.039). Log rank test analysis showed a statistically significant direct correlation between nuclear maspin expression and disease-free intervals after surgical treatment calculated in months (P = 0.028). A significant inverse correlation was disclosed between nuclear maspin staining and MIB-1 (P = 0.028). A trend of increasing p27 expression was noted in cases with positive nuclear maspin expression. Nuclear maspin expression was not statistically correlated with p53 expression. A trend towards direct correlation between cytoplasmic maspin expression and squamous cell carcinoma histological grade (G) was apparent. Cytoplasmic maspin expression did not correlate with p53, MIB-1 or p27 expression. CONCLUSIONS: These preliminary results suggest that nuclear location of maspin is a good prognostic factor in laryngeal carcinoma.

Treatment of complications of parotid gland surgery.

Although several reports in the literature have documented the surgical technique, and the oncological outcome achieved with parotidectomy, only a few articles have described the complications of parotid gland surgery and their management. Several complications have been reported in parotid surgery. We re-classified the complications of parotidectomy in intra-operative and post-operative (early and late). The commonest complications after parotidectomy are temporary or permanent facial palsy and Frey's syndrome.

Facial nerve paralysis secondary to acute otitis media in infants and children.

Nowadays, facial paralysis is an uncommon complication of acute inflammation of the middle ear, with an estimated incidence of 0.005%; it was not so rare in the pre-antibiotic era, occurring in 0.5-0.7% of middle ear inflammatory processes. We would like to highlight this complication of acute otitis media, a common paediatric complaint. We present three new cases of facial palsy in children with acute otitis media and discuss the etiological mechanisms and different approaches to the treatment; a flow chart for facial paralysis in acute otitis media is also presented. Our three patients recovered completely after mastoidectomy (first two cases) and myringotomy with antibiotic therapy (third case). Facial paralysis is an uncommon complication of otitis media which requires appropriate care. Following our experience and revision of literature on the subject, antibiotic therapy and myringotomy are the first-line procedures. Surgery should be employed in case of acute or coalescent mastoiditis, suppurative complications and lack of clinical regression.

Bezold's abscess in children: case report and review of the literature.

The introduction of antibiotics in the treatment of suppurative otitis media has significantly decreased the incidence of complications. Reports of Bezold's abscess secondary to this disorder are rare, particularly in infants and young children, in whom mastoid bone pneumatization is not yet complete. We present a case of Bezold's abscess occurring in a child aged 18 months. The literature is reviewed and methods to accurately diagnose this complication are emphasized.

Langerhans' cell histiocytosis: temporal bone involvement.

In Langerhans' cell histiocytosis, radiological findings on temporal bone involvement show destructive bone lesions involving the mastoid, with the squamous part and middle ear less affected. Computed tomography (CT) is the preferred imaging modality for describing the extent of temporal bone involvement. CT also has an important role in monitoring disease activity and response to treatment. Bone scintigraphy seems to be less sensitive than radiography in detection of these lesions.

[Algodystrophic syndrome of the temporo-mandibular joint: a clinical experience]. / La sindrome algo-disfunzionale dell'articolazione temporomandibolare. Nostra esperienza clinica.

Algo-dysfunctional syndrome (ADS) of the temporo-mandibular joint (TMJ) is frequently encountered and, since its clinical expression is extremely polymorphic, it is often misdiagnosed. As there are many causes for ADS, even in a single patient, in line with the most recent interpretations found in the literature, an attempt was made to determine how important the lack of muscular coordination is in the onset of clinical symptoms. The study was conducted on 48 patients (32 females, 16 males, age range 17-68 years, average age 41.7 years) with ADS, clinically diagnosed according to the criteria defined by Rendell et al. The patients belonged to three distinct groups: -Group 1: patients with ADS of articular origin (9 cases); -Group 2: patients with ADS of dental and/or periodontal origin (18 cases); -Group 3: patients with ADS for which there was no apparent cause (21 cases). All patients were treated with a rehabilitation protocol aimed at eliminating the muscle spasm and restoring correct coordination. The results obtained showed that conservative treatment to resolve the muscle spasm gave positive results in 69% of the cases. The patients with concomitant articular pathology proved the least responsive to treatment. It was, therefore, considered likely that the main cause for clinical expression of this pathology is the muscle spasm itself. On this basis it can be concluded that muscular rehabilitation of the TMJ is valid in the treatment of ADS as it has proved able to break the vicious cycle of symptoms at the base of this pathology.

Albumin-binding surfaces: in vitro activity.

Immobilized monoclonal antibodies (Mabs) have been used to attract specific molecules to a solid surface from complex mixtures such as blood, plasma or serum, thereby directing the response to the modified substrate, a key goal in rational biomaterial design. The nature of the Mab dictated the nature of the response: anti-albumin antibodies were used to prevent cell and platelet adhesion in vitro, whilst anti-fibronectin Mabs promoted attachment. Patterned surfaces could be formed, bearing Mabs that generated adhesive and non-adhesive regions. Fibrinogen adsorption from plasma showed a Vroman peak on unmodified control polymer, which was reduced by 64% in the presence of surface-bound anti-albumin Mab. Immobilization of a control Mab reduced fibrinogen adsorption only slightly, implying an albumin-mediated effect. In static tests, platelet adhesion from human platelet rich plasma was significantly reduced by the immobilization of anti-HSA Mab when compared to the untreated FEP surface (p < 0.0001). This effect was also seen with citrated blood flowing through Mab-treated polyurethane tubing at a shear rate of 132 s(-1) (p=0.034). Since platelets and proteins (as blood, plasma or serum) were introduced to the surface simultaneously, the generation of a defined protein film must have been sufficiently rapid as to shape the platelet or cell response.

[The evolution of the techniques used to correct nasal septum function]. / La evoluzione delle tecniche di correzione funzionale del setto nasale.

At the dawn of rhinosurgery, the otolaryngologist operated on the nasal septum while a plastic surgeon handled treatment of the "noble" portion of the nose, i.e. the nasal pyramid. However, the plastic surgeon dealt more with esthetics than with function. Discussion and doubts revolved around the priorities of septum vs. pyramid treatment. Such doubts have often gone unresolved and has led to an unusual dichotomy in nasal surgery: the break down into septoplasty and rhinoplasty. This scission has fallen by the wayside during the course of the years. Indeed, today, where necessary, one tends associate corrective rhinoplasty during the course of septal procedures. During this historical review of functional surgery of the nasal septum, some mention is made of the numerous techniques and variations thereof which have been presented by various authors.

[The history and evolution of the surgical techniques in rhinoplasty]. / Storia ed evoluzione della tecnica chirurgica nella rinoplastica.

Few other forms of surgery embody the authentic, full essence of surgery as does rhinoplasty, where functional results are joined to meet one's innermost expectations. the present work reviews the main stages in the course of the evolution of the philosophy and surgical techniques adopted to resolve both the functional and esthetic problems of the nose. This provides a broad view of the issues every surgeon has had to deal with in this regard. The history of rhinoplasty once more teaches us that the evolution of a discipline hinges around the daily renewal of one's preparation through study, observation and insights.
