Abstract
Botulinum toxin (BTX) is a neurotoxic protein produced by Clostridium botulinum, an anaerobic bacterium. BTX therapy is a safe and effective treatment when used for functional silencing of the salivary glands in disorders such as sialoceles and salivary fistulae that may have a post-traumatic or post-operative origin. BTX injections can be considered in sialoceles and salivary fistulae after the failure of or together with conservative treatments (e.g. antibiotics, pressure dressings, or serial aspirations). BTX treatment has a promising role in chronic sialadenitis. BTX therapy is highly successful in the treatment of gustatory sweating (Frey's syndrome), and could be considered the gold standard treatment for this neurological disorder.

Abstract
Background Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major
health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following:
• Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy
with small diameter endoscopes.
• Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability.
• Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour
threshold, and/or one of odour identification or discrimination.
• Comprehensive chemosensory assessment should include gustatory screening.
• Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
AIMS Peak Nasal Inspiratory Flow (PNIF) is an easy method to assess nasal patency. Normative unilateral PNIF data in adults have been proposed. The study purpose was to compare PNIF and unilateral PNIF values to total and unilateral nasal resistances measured by anterior active rhinomanometry (AAR) in subjects with and without nasal obstruction to see whether unilateral PNIFis sensitive to detect nasal obstruction. METHODS AND RESULTS Measurements of PNIF, unilateral PNIF and AAR were performed in 125 volunteers. Seventy of them were healthy subjects not complaining of nasal symptoms and entered into the study as the'normal' group. The other group consisted of fifty-five symptomatic subjects.Data were analysed to show the correlation between PNIF, unilateral PNIF and nasal resistances. The ability of PNIF and AAR in predicting pathologies were compared by receiver operating characteristic (ROC) analysis indicating that PNIF and AAR have a similar and significant power to discriminate pathologic from healthy subjects. CONCLUSION The measurement of unilateral PNIF could be a helpful method to support the diagnosis of nasal blockage also in those cases with single nostril obstruction, but, in cases of doubt, AAR should also be performed to improve diagnostic accuracy.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) secondary to hypertension has been accepted to prevent heart failure (HF) while paradoxically increasing cardiovascular morbi-mortality. OBJECTIVES To evaluate whether antihypertensive treatment inhibits LVH, restores beta-adrenergic response and affects myocardial oxidative metabolism. METHODS Ninety spontaneously hypertensive rats (SHR) were distributed into groups and treated (mg/kg, p.o.) with: losartan 30 (L), hydralazine 11 (H), rosuvastatin 10 (R), carvedilol 20 (C). Hypertension control group comprised 18 normotensive rats (Wistar-Kyoto, WKY). Following euthanasia at 16months, contractility was measured in 50% of rats (Langendorff system) before and after isoproterenol (Iso) 10-9M, 10-7M and 10-5M stimulation. Left ventricular weight (LVW) was measured in the remaining hearts, and normalized by BW. Expression of thioredoxin 1 (Trx-1), peroxyredoxin 2 (Prx-2), glutaredoxin 3 (Grx-3), caspase-3 and brain natriuretic peptide (BNP) was determined. RESULTS Systolic blood pressure (mmHg): 154±3 (L), 137±1 (H), 190±3 (R)*, 206±3 (SHR)*, 183±1 (C)**, and 141±1 (WKY) (*p<0.05 vs. L, H, WKY, **p<0.05 vs. L, H, WKY, SHR). LVW/BW was higher in SHR and R (p<0.05). Groups SHR, R and C evidenced baseline contractile depression. Response to Iso 10-5M was similar in WKY and L. Expression of Trx-1, Prx-2 and Grx-3 increased in C, H, R and L (p<0.01). CONCLUSIONS Present findings argue against the traditional idea and support that LVH might not be required to prevent HF. Increased expression of thioredoxins by antihypertensive treatment might be involved in protection from HF.

Abstract
Objective measures can be used to assist the clinician to diagnose and treat nasal obstruction and also to quantify nasal obstruction in research. Objective measurements of nasal obstruction are as important as objective measurements of lung function. peak nasal inspiratory flow (PNIF), acoustic rhinometry (AR) and rhinomanometry (RM), with their specific peculiarity, assess different aspects of nasal obstruction. From the studies available in the literature, it seems that these methods roughly correlate with each other and that all of them can be alternatively utilized very well in research as well as in clinical practice. This review describes the various methods that can be used to measure nasal patency, airflow and resistance, mainly peak nasal inspiratory flow, rhinomanometry and acoustic rhinometry. PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population. PNIF normative data are available for children, adults and elderly subjects, and the availability of unilateral PNIF normal values allows evaluation of nasal sides separately. Just as in the lower airways, objective and subjective evaluation gives different information that together optimizes the diagnosis and the treatment of our patients. We argue that PNIF should be used regularly in every outpatient clinic that treats patients with nasal obstruction.

Abstract
Background Wiskott-Aldrich syndrome (WAS) is a severe X-linked immunodeficiency characterized by microthrombocytopenia, eczema, recurrent infections, and susceptibility to autoimmunity and lymphomas. Hematopoietic stem cell transplantation is the treatment of choice; however, administration of WAS gene–corrected autologous hematopoietic stem cells has been demonstrated as a feasible alternative therapeutic approach. Objective Because B-cell homeostasis is perturbed in patients with WAS and restoration of immune competence is one of the main therapeutic goals, we have evaluated reconstitution of the B-cell compartment in 4 patients who received autologous hematopoietic stem cells transduced with lentiviral vector after a reduced-intensity conditioning regimen combined with anti-CD20 administration. Methods We evaluated B-cell counts, B-cell subset distribution, B cell–activating factor and immunoglobulin levels, and autoantibody production before and after gene therapy (GT). WAS gene transfer in B cells was assessed by measuring vector copy numbers and expression of Wiskott-Aldrich syndrome protein. Results After lentiviral vector-mediated GT, the number of transduced B cells progressively increased in the peripheral blood of all patients. Lentiviral vector-transduced progenitor cells were able to repopulate the B-cell compartment with a normal distribution of B-cell subsets both in bone marrow and the periphery, showing a WAS protein expression profile similar to that of healthy donors. In addition, after GT, we observed a normalized frequency of autoimmune-associated CD19+CD21−CD35− and CD21low B cells and a reduction in B cell–activating factor levels. Immunoglobulin serum levels and autoantibody production improved in all treated patients. Conclusions We provide evidence that lentiviral vector-mediated GT induces transgene expression in the B-cell compartment, resulting in ameliorated B-cell development and functionality and contributing to immunologic improvement in patients with WAS.

Abstract
Among male patients affected by Kallmann syndrome, a genetically determined disease due to defective neural migration leading to hypogonadropic hypogonadism and hypo/anosmia, about 40% present the peculiar phenomenon of mirror movements, i.e. involuntary movements mirroring contralateral voluntary hand movements. Several pathogenic hypotheses have been proposed, but the ultimate neurological mechanisms are still elusive. The aim of the present study was to investigate brain anatomical substrates of mirror movements in Kallmann syndrome by means of a panel of quantitative MRI analyses. Forty-nine male Kallmann syndrome patients underwent brain MRI. The study protocol included 3D-T1-weighted gradient echo, fluid attenuated inversion recovery and diffusion tensor imaging. Voxel-based morphometry, sulcation, curvature and cortical thickness analyses and tract based spatial statistics were performed using SPM8, Freesurfer and FSL. All patients underwent a complete physical and neurological examination including the evaluation of mirror movements (according to the Woods and Teuber criteria). Kallmann syndrome patients presenting with mirror movements (16/49, 32%) displayed the following brain changes: 1) increased gray matter density in the depth of the left precentral sulcus behind the middle frontal gyrus; 2) decreased cortical thickness in the precentral gyrus bilaterally, in the depth of right precentral sulcus and in the posterior portion of the right superior frontal gyrus; and 3) decreased fractional anisotropy in the left hemisphere involving the temporal lobe and peritrigonal white matter. No differences were shown by cortical curvature and sulcation analyses. The composite array of brain changes observed in Kallmann syndrome patients with mirror movements likely represents the anatomical-structural underpinnings leading to the peculiar derangement of the complex circuitry committed to unilateral hand voluntary movements.

Abstract
OBJECTIVES Olfaction is based on the function of the nasal olfactory receptors. Children can well detect and respond to odors in order to have information about food and environment. Rapid maxillary expansion seems to improve dental class and increase nasal patency correcting oral respiration in children. Nevertheless, there are no studies demonstrating that expansion in pediatric patients could influence olfactory sensitivity. The aim of this study was to evaluate olfactory threshold and nasal patency in children aged from 6 to 12 years before and after rapid maxillary expansion. METHOD N-butanol olfactory thresholds, anterior active rhinomanometry, and peak nasal inspiratory flow were measured in 12 children (6-12 years) before (T0), 20 days (T1), and 6 months after rapid maxillary expansion application (T2). RESULTS A significant lower olfactory threshold was found comparing T2 and T0 N-butanol olfactory threshold values (p=0.038). Peak nasal inspiratory flow showed a significant improvement both at T1 and T2, with respect to T0 values (p=0.043 and p=0.0001, respectively). T2 nasal resistances showed a trend towards a significant reduction when compared with T1 values (p=0.15). CONCLUSION This pilot study suggested that rapid maxillary expansion may lead to improved N-butanol olfactory thresholds, at least 6 months after palatal expansion. Furthermore, rapid maxillary expansion seems to improve peak nasal inspiratory flow values, and finally although with lower sensitivity, reduce nasal resistances as measured by rhinomanometry.

Abstract
Olfactory receptor (OR) expression is also present in the sperm cells and could mediate sperm chemotaxis. OR1D2 was the first OR expressed in the testis demonstrated to be involved in chemotaxis and to be expressed also in the nose with a similar behavior. Bourgeonal is the OR1D2 most potent known agonist. Infertility affects ~15 % of couples in western countries and sometimes it is unexplained. This pilot study compared the bourgeonal olfactory thresholds, the ability of sperm to sense the bourgeonal and the frequency of 13 single nucleotide polymorphisms (SNPs) of OR1D2 gene in nine males suffering of unexplained infertility with a control group of 15 healthy males. The mean olfactory threshold for bourgeonal was statistically different between the study group (10.5 ± 3.7; median 12.3) and the control group (14.0 ± 2.8; median 15.5) (p = 0.006). Statistical analysis showed a significantly higher percentage of spermatozoa that migrated toward the capillaries filled with bourgeonal in the control group compared to the study group (p < 0.0001). Sperm migration was equally inhibited in both groups of subjects when, together with bourgeonal, capillaries were filled with undecanal, a strong bourgeonal inhibitor (p = 0.42). The 13 SNPs of OR1D2 revealed a statistically significant difference for allele and genotype frequency of rs769423 in study group versus control group (p = 0.02). The present preliminary study seems to confirm the important role of OR1D2 both in nose and spermatozoa and may explain the idiopathic infertility of the study group. Further studies on larger series are mandatory to confirm our preliminary evidence.

Abstract
AIMS Swimmers commonly complain of nasal symptoms probably due to mucosal irritation caused by chlorinated water. The aim of the present prospective study was to investigate changes in nasal function and cytology in a cohort of 15 volunteer competitive swimmers, as compared with a control group of 15 competitive athletes practicing other sports. METHODS Olfactory threshold for n-butanol was measured in a population of competitive swimmers. Changes in nasal function and cytology were compared between the two groups of volunteer competitive athletes. RESULTS There were no significant differences between the two groups in terms of mean 20-Item Sino-Nasal Outcome Test scores, peak nasal inspiratory flow, pulmonary peak expiratory flow, or total nasal resistance on anterior active rhinomanometry. Nasal mucociliary transport time (MCTt) was significantly shorter for the non-swimmers than for the swimmers. The mean olfactory threshold for n-butanol in the swimmers was significantly lower than in the other group of athletes. CONCLUSIONS Data seem to confirm the utility of MCTt in studying nasal mucosa damage caused by chlorinated water. The present results also support the hypothesis of a role for the olfactory threshold in evaluating damage to the olfactory mucosa exposed to chlorinated water.

Abstract
Cervical masses are a common clinical finding, but differential diagnosis is often challenging. Acute neck swellings are often due to deep cervical space infections that have originated at oral or oropharyngeal sites. Deep neck infections originating elsewhere are not rare; however, they are difficult to diagnose, and their origins remain obscure in 20% of cases. Neck swellings that originate in the middle ear are very rare, with only a few reported in the scientific literature. Here we report an atypical case of Bezold's abscess caused by the recurrence of a middle ear cholesteatoma. In patients with neck swelling and a history of primary cholesteatoma of the middle ear, otolaryngologists should consider regional recurrence of disease a possibility even several years after the primary surgery.

Abstract
STATEMENT OF PROBLEM The respiratory nasal effects of physical exercise have been extensively investigated; on the other hand there are no data regarding olfactory threshold modification after aerobic physical exercise. METHODS The present prospective study investigated the modifications in nasal respiratory flows and olfactory thresholds after controlled aerobic physical exercise in a cohort of 15 adult, healthy volunteers. The Peak Nasal Inspiratory Flow (PNIF), and the Sniffin’ Sticks olfactory threshold test were used for our determinations. MAIN RESULTS The mean PNIF after physical exercise was significantly higher than the mean PNIF value found before physical exercise. Statistical analysis ruled out any significant difference between mean olfactory thresholds pre vs post physical exercise. PRINCIPAL CONCLUSIONS These outcomes confirmed PNIF sensitivity and reliability also in determining the changes in nasal patency occurring after physical exercise. The active vasoconstriction of nasal mucosa associated with the reduction of blood flow to the olfactory epithelium due to physical exercise may be compensated for by the increase of olfactory molecules that reach the olfactory mucosa because of nasal mucosal shrinkage: this mechanism could explain the stability of mean olfactory threshold after physical exercise.

Abstract
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.

Abstract
AIMS Angiogenesis is essential for malignancies growth. CD105 is a proliferation-associated protein abundantly expressed in angiogenic endothelial cells. The aim of this study has been to determine the expression of CD105 in laryngeal squamous cell carcinoma (SCC) and to investigate the role of CD105-assessed mean vascular density (MVD) in predicting patients' prognosis. METHODS The sections of 43 consecutive cases of laryngeal SCC were stained with mouse monoclonal antibody CD105. All the measures were performed by a computer-based image analysis system. The percentage of the fields occupied by CD105-assessed micro-vessels was determined. RESULTS The mean CD105-assessed MVD were 11% and 6% in laryngeal SCC with and without malignancy recurrence, respectively. Multivariate logistic regression stated that CD105-assessed MVD was significantly related to disease recurrence (p=0.030). CONCLUSIONS Our preliminary results suggest that CD105-assessed MVD may be a valuable parameter for predicting patients having an increased risk of developing laryngeal carcinoma loco-regional recurrence.
