RESUMEN
PURPOSE OF REVIEW: Given that allergic rhinitis (AR) commonly coexists with other diseases, the present narrative review attempts a brief presentation of current theories on multimorbidities in relation to phenotypes, genotypes, age, and treatment responses with the term "multimorbidities" indicating the uncertainty regarding the primary defect, organ, or pathophysiologic mechanism involved. RECENT FINDINGS: Though age-related manifestations allow for the generation of several hypotheses on AR's specific mechanisms, the various theories regarding the initiation or the aggravation of atopic disorders have yet to be proved. Multimorbid AR seems to have a different genetic basis from "stand-alone" AR as well a more severe phenotype. Most studies on the treatment of AR and its multimorbidities focus on allergen immunotherapy, which improves the atopic symptoms and may play a preventive role in the onset of new allergen sensitizations. The use of biological factors may also have a beneficial effect, even though it has currently been approved only for some comorbidities of AR, such as asthma. Employing the use of phenotypes and genotypes concerning multimorbidity broadens current knowledge, but further research is needed to develop diagnostic, stratificational, and predictive algorithms for single and multimorbid allergic diseases (Fig. 1). The real-time data obtained by mobile apps and the new insights on the pathophysiology of AR and its comorbidities will permit both timed preventive measures and better individualized and effective antiallergic treatment.

BACKGROUND: Mobile technology may help to better understand the adherence to treatment. MASK-rhinitis (Mobile Airways Sentinel NetworK for allergic rhinitis) is a patient-centred ICT system. A mobile phone app (the Allergy Diary) central to MASK is available in 22 countries. OBJECTIVES: To assess the adherence to treatment in allergic rhinitis patients using the Allergy Diary App. METHODS: An observational cross-sectional study was carried out on all users who filled in the Allergy Diary from 1 January 2016 to 1 August 2017. Secondary adherence was assessed by using the modified Medication Possession Ratio (MPR) and the Proportion of days covered (PDC) approach. RESULTS: A total of 12 143 users were registered. A total of 6 949 users reported at least one VAS data recording. Among them, 1 887 users reported ≥7 VAS data. About 1 195 subjects were included in the analysis of adherence. One hundred and thirty-six (11.28%) users were adherent (MPR ≥70% and PDC ≤1.25), 51 (4.23%) were partly adherent (MPR ≥70% and PDC = 1.50) and 176 (14.60%) were switchers. On the other hand, 832 (69.05%) users were non-adherent to medications (MPR <70%). Of those, the largest group was non-adherent to medications and the time interval was increased in 442 (36.68%) users. CONCLUSION AND CLINICAL RELEVANCE: Adherence to treatment is low. The relative efficacy of continuous vs on-demand treatment for allergic rhinitis symptoms is still a matter of debate. This study shows an approach for measuring retrospective adherence based on a mobile app. This also represents a novel approach for analysing medication-taking behaviour in a real-world setting.

PURPOSE OF REVIEW: Our scope is the presentation of research and clinical progresses in relation to precision medicine that are expected to alter our clinical practice in relation to chronic rhinosinusitis (CRS). Current knowledge on phenotypes and endotypes, biomarkers, and clinical markers for diagnosis, medical and surgical therapy, and prognosis is presented as well as the role of precision medicine in United Airway Disease and SCUAD (severe-uncontrolled chronic upper airway inflammation). RECENT FINDINGS: Current technological progresses, mostly in relation to molecular biology and information technology, have permitted more detailed pathophysiological assessments and multidimensional approaches in airways diseases. Based on the concept of united airways diseases, new classification schemes, called endotypes, have been proposed for CRS. In addition, novel biological treatments that have been introduced for the treatment of asthma show great promise as well for severe uncontrolled cases of CRS with nasal polyps. Central to this approach are new biomarkers that are being examined in relation to complex bio-clinical traits of CRS. As this narrative review of the aforementioned precision medicine initiatives in relation to CRS advances, a modification of current practice is expected not only for severe chronic upper airways diseases in tertiary centers but also for milder and more common cases that are being encountered in the community.

The term SCUAD (severe chronic upper airway disease) has been previously introduced to describe cases with upper airway disorders and symptoms not adequately controlled despite correct diagnosis and management. It has been so far applied mainly in adults and no specific focus has been given on the pediatric population. When the term SCUAD is considered for children specifically, a series of issues may arise. These issues involve accurate definition, epidemiology, clinical characteristics, pathophysiology, and socioeconomic implications. These issues seem to clearly differentiate adult from pediatric SCUAD. We attempt to shed light on these issues in an effort to provide directions for future guideline development and research. In this context, P-SCUAD (pediatric severe chronic upper airway disease) is hereby introduced.

Objective To test feasibility by enhancing the knowledge and skills of general practitioners (GPs) in managing ear, nose, and throat (ENT) morbidity within primary care settings through a three-hour educational course. Methods A structured course focused on common ENT disorders was conducted. Case morbidity was selected based on appropriate criteria. The participants (n=34) were GPs randomly assigned to control and intervention groups. A questionnaire assessed knowledge, attitudes, and practices (KAP) before and after the course using proper analysis. Results The intervention group showed significant improvement in responses within five of sixteen questions (p<0.05). Participants demonstrated greater knowledge responsiveness in relation to epistaxis and CENTOR criteria, while knowledge response improvement was poor in regard to vestibular morbidity. Overall improvement in KAP scores (p<0.05), with high effect sizes, was achieved before and after the seminar. Conclusions The three-hour ENT course for GPs was found to be feasible, emphasizing the need for targeted short-duration courses within GP education supported by locally relevant information on common ENT conditions. Future research should explore the long-term impact of similar collaborative interventions in primary care.
RESUMEN
Primary healthcare is the pillar of a well-functioning healthcare system. General practitioners (GPs) should have a broad skillset to cope with the various conditions they encounter in everyday practice. Ear, nose, and throat (ENT) cases are some of the most common reasons for seeking care. The study aimed to define the frequency and type of ENT disorders seen in the emergency department of a tertiary hospital in Greece. All patients examined by an ENT specialist in the emergency department setting, within a year, were recorded, as well as all referrals from private practice or primary care facilities. From September to December 2021, data were collected from patients who agreed to complete a two-minute survey, namely, the Generalized Anxiety Disorder Scale (GAD-2) questionnaire. During the study year, 4542 cases were documented, from which the most common conditions listed were external otitis (6.9%/314), epistaxis (6.7%/305), and impacted earwax (5.7%/261). The diagnoses that led to hospitalization were 336 and the most common were peritonsillar abscess (16.4%/55), epistaxis (8.0%/27), and facial nerve paralysis (7.4%/25). Referrals from GPs working in the public sector represented more than the half of the total. There was a significant correlation between an increased number of hospital visits and an increased GAD-2 score, in the semester before the current visit (p < 0.001). Referrals to ENT specialists represent around 5% of all cases examined, and about 8% of all visits required hospitalization. Interdisciplinary clinical and research investment into GP training is compulsory to regulate ENT referrals by GPs.
RESUMEN
BACKGROUND: Little is known about the effect of smoking cessation on airway inflammation. Secretory Leukocyte Protease Inhibitor (SLPI), Clara Cell protein 16 (CC16), elafin and human defensin beta-2 (HBD-2) protect human airways against inflammation and oxidative stress. In this longitudinal study we aimed to investigate changes in sputum and nasal lavage SLPI, CC16, elafin and HBD-2 levels in healthy smokers after 6 and 12 months of smoking cessation. METHODS: Induced sputum and nasal lavage was obtained from healthy current smokers (n = 76) before smoking cessation, after 6 months of smoking cessation (n = 29), after 1 year of smoking cessation (n = 22) and from 10 healthy never smokers. SLPI, CC16, elafin and HBD-2 levels were measured in sputum and nasal lavage supernatants by commercially available ELISA kits. RESULTS: Sputum SLPI and CC-16 levels were increased in healthy smokers before smoking cessation versus never-smokers (p = 0.005 and p = 0.08 respectively). SLPI and CC16 levels did not differ before and 6 months after smoking cessation (p = 0.118 and p = 0.543 respectively), neither before and 1 year after smoking cessation (p = 0.363 and p = 0.470 respectively). Nasal lavage SLPI was decreased 12 months after smoking cessation (p = 0.033). Nasal lavage elafin levels were increased in healthy smokers before smoking cessation versus never-smokers (p = 0.007), but there were no changes 6 months and 1 year after smoking cessation. CONCLUSIONS: Only nasal lavage SLPI decrease after 1 year after smoking cessation. We may speculate that there is an ongoing inflammatory process stimulating the production of counter-regulating proteins in the airways of healthy ex-smokers.

Rhinitis describes a pattern of symptoms as a result of nasal inflammation and/or dysfunction of the nasal mucosa. It is an umbrella entity that includes many different subtypes, several of which escape of complete characterization. Rhinitis is considered as a pathologic condition with considerable morbidity and financial burden on health care systems worldwide. Its economic impact is further emphasized by the fact that it represents a risk factor for other conditions such as sinusitis, asthma, learning disabilities, behavioral changes, and psychological impairment. Rhinitis may be associated with many etiologic triggers such as infections, immediate-type allergic responses, inhaled irritants, medications, hormonal disturbances, and neural system dysfunction. It is basically classified into three major clinical phenotypes: allergic rhinitis (AR), infectious rhinitis, and non-allergic, non-infectious rhinitis (NAR). However, this subdivision may be considered as an oversimplification because a combined (mixed) phenotype exists in many individuals and different endotypes of rhinitis subgroups are overlapping. Due to the variety of pathophysiologic mechanisms (endotypes) and clinical symptoms (phenotypes), it is difficult to develop clear guidelines for diagnosis and treatment. This study aims to review the types of allergic and non-allergic rhinitis, providing a thorough analysis of the pathophysiological background, diagnostic approach, and main treatment options.
RESUMEN
BACKGROUND: MASK-air® is an app that supports allergic rhinitis patients in disease control. Users register daily allergy symptoms and their impact on activities using visual analog scales (VASs). We aimed to assess the concurrent validity, reliability, and responsiveness of these daily VASs. METHODS: Daily monitoring VAS data were assessed in MASK-air® users with allergic rhinitis. Concurrent validity was assessed by correlating daily VAS values with those of the EuroQol-5 Dimensions (EQ-5D) VAS, the Control of Allergic Rhinitis and Asthma Test (CARAT) score, and the Work Productivity and Activity Impairment Allergic Specific (WPAI-AS) Questionnaire (work and activity impairment scores). Intra-rater reliability was assessed in users providing multiple daily VASs within the same day. Test-retest reliability was tested in clinically stable users, as defined by the EQ-5D VAS, CARAT, or "VAS Work" (i.e., VAS assessing the impact of allergy on work). Responsiveness was determined in users with two consecutive measurements of EQ-5D-VAS or "VAS Work" indicating clinical change. RESULTS: A total of 17,780 MASK-air® users, with 317,176 VAS days, were assessed. Concurrent validity was moderate-high (Spearman correlation coefficient range: 0.437-0.716). Intra-rater reliability intraclass correlation coefficients (ICCs) ranged between 0.870 (VAS assessing global allergy symptoms) and 0.937 (VAS assessing allergy symptoms on sleep). Test-retest reliability ICCs ranged between 0.604 and 0.878-"VAS Work" and "VAS asthma" presented the highest ICCs. Moderate/large responsiveness effect sizes were observed-the sleep VAS was associated with lower responsiveness, while the global allergy symptoms VAS demonstrated higher responsiveness. CONCLUSION: In MASK-air®, daily monitoring VASs have high intra-rater reliability and moderate-high validity, reliability, and responsiveness, pointing to a reliable measure of symptom loads.
RESUMEN
Besides the anatomic continuity of the upper and lower airways, inflammation in one part of the airway influences the homeostasis of the other. The mechanisms underlying this interaction have been studied primarily in allergic disease, showing systemic immune activation, induction of inflammation at a distance, and a negative impact of nasal inflammation on bronchial homeostasis. In addition to allergy, other inflammatory conditions of the upper airways are associated with lower airway disease. Rhinosinusitis is frequently associated with asthma and chronic obstructive pulmonary disease. The impairment of purification, humidification, and warming up of the inspired air by the nose in rhinosinusitis may be responsible in part for bronchial pathology. The resolution of sinonasal inflammation via medical and/or surgical treatment is responsible for the beneficial effect of the treatment on bronchial disease. This article provides a comprehensive overview of the current knowledge of upper and lower airway communication beyond allergic disease.

We present a case of a desmoid tumor recurrence in a patient with a history of a resected desmoid tumor of the right neck area with free surgical margins six months earlier. The neoplasm was found to invade the parapharyngeal space, and wide excision was performed including most of the sternocleidomastoid muscle (SCM), the thrombosed internal jugular vein (IJV), and the infiltrated spinal accessory nerve (SAN). The histopathologic findings displayed free microscopic margins, with close margins at the site of the parapharyngeal space extension. After 3 months, there was no sign of tumor recurrence. After 6 months, local tumor recurrence was identified on clinical examination and imaging. The decision of the Oncology Board was further treatment with radiotherapy (RT). Response to treatment was satisfactory, and the patient was on close follow-up for twelve months. Desmoid tumors are very rare benign neoplasms of mesenchymal origin with negligible mortality but high morbidity, due to their high recurrence rates, local tissue infiltration, and unpredictable disease course and response to treatment. No universally acceptable treatment protocols have been introduced to date. Appropriate patient counseling and close follow-up are warranted in all cases.
RESUMEN
BACKGROUND: Hypocalcaemia is a common and serious complication after thyroidectomy. The purpose of this study is to assess the effectiveness of first postoperative day parathyroid hormone (PTH) measurement in order to predict the presence and severity of postthyroidectomy hypocalcaemia. METHODS: One hundred consecutive cases undergoing total thyroidectomy in a tertiary referral center were prospectively assessed. Preoperative measurements of PTH were compared with postoperative levels in the first morning after surgery. All cases of hypocalcaemia were recorded and evaluated with regard to preoperative and postoperative levels of PTH. RESULTS: A decrease of 56% of PTH levels on the first postoperative day could accurately predict postoperative hypocalcaemia with a sensitivity and specificity of 80%. CONCLUSION: Serum PTH levels on the first postoperative day may be used as a reliable predictive marker for calcium supplementation need and even prolonged hospitalization in cases undergoing total thyroidectomy.

OBJECTIVE: To investigate the increased incidence of papillary thyroid cancer as found in specimens of total thyroidectomies and potential correlation with etiological factors. STUDY DESIGN AND SETTING: A retrospective study on patients who underwent total thyroidectomy, from 1990 to 2004, in an academic tertiary referral medical center. Patients' records were placed in a database, which included medical condition, history, and demographics. Histopathological slides were reviewed with special focus on papillary cancer. RESULTS: Our series consisted of 2379 patients. Thyroid cancer was confirmed in 354 patients (14.88%). Papillary carcinoma represented the most frequent type (316 patients, 89.26%). Increased incidence of papillary carcinomas was noticed after 1995, reaching the maximum value in the year 2000. After 2000, there was a descending trend and then a plateau. CONCLUSION: The increased incidence of papillary thyroid cannot be attributed to dietary patterns or increased diagnostic and therapeutic activity. It is likely to be associated with increased radiation and may be associated with the Chernobyl fallout.

OBJECTIVE: To introduce and assess a new method of tonsillectomy with thermal welding technology (TWT) using the thermal ligating shear (TLS(2)), in pediatric population. METHOD: TWT provides a new surgical instrument that combines heat and pressure to simultaneously coagulate and divide tissue. Among the headpieces available for the TWT generator, the TLS(2) handpiece was selected. A prospective study was conducted in our Department, on 60 children who underwent tonsillectomy with the use of TWT. Inclusion criteria were obstructive sleep apnea syndrome, peritonsilar abscess history and chronic tonsillitis. Patients undergoing adenoidectomy, or any other procedure together with tonsillectomy were excluded from this study. All patients' data, including intraoperative blood loss, operation time and complication rates were recorded in a database. RESULTS: Our series consisted of 60 patients (39 male and 21 female). There was no measurable bleeding during surgery in any of the cases. The mean operative time was 20 min. Only one case of postoperative hemorrhage occurred. Mild uvula edema was noticed in 25 patients. CONCLUSION: TWT is a safe method for tonsillectomy. Among the several handpieces available for the TWT generator, the TLS(2) is very effective and easy to use in tonsillectomy procedures, providing sufficient heamostasis and diminished operative time.

OBJECTIVE: To compare laser-assisted tympanostomy (LAT) with radiofrequency myringotomy (RFM), as well as the effectiveness of mitomycin C (MC) on the above techniques, in rabbits. STUDY DESIGN: Experimental animal research protocol. SETTING: University of Crete, School of Medicine, Medical Experimental Education and Research Center. METHODS: Bilateral myringotomies were performed under general anesthesia on 40 rabbits. LAT was performed on 20 animals (40 ears) and RFM on the remaining 20 animals (40 ears). MC (0.3 mg/mL) pledgets were applied to the right ears and saline pledgets to the left ears. Animals were monitored weekly using otomicroscopy until myringotomy closure. Kaplan-Meier survival techniques were used to compare myringotomy patency times. INTERVENTIONS: Under general anesthesia, bilateral LAT was performed on 20 rabbits and bilateral RFM on 20 rabbits. MAIN OUTCOME MEASURES: Myringotomy patency time. RESULTS: The mean patency times of the saline-treated ears were: 1.85 weeks (95% confidence interval [CI], 1.556-2.144 wk) for the LAT group and 1.70 weeks (95% CI, 1.494-1.906 wk) for the RFM group. This difference was not significant (p > 0.5). MC application significantly prolonged mean patency time (p < 0.0001) in both LAT and RFM groups. The mean patency times in the MC-treated ears were 5.45 weeks (95% CI, 5.226-5.674 wk) for the LAT group and 5.55 weeks (95% CI, 5.285-5.815 wk) for the RFM group. This difference was not significant (p > 0.5). CONCLUSION: There is no significant difference in myringotomy patency times between LAT and RFM techniques in rabbits, whereas MC significantly prolongs the patency rate of either technique.

OBJECTIVE: To assess the use of radiofrequency myringotomy in combination with mitomycin C as an alternative myringotomy technique on rabbits. STUDY DESIGN: Experimental animal research protocol. SETTING: University of Crete, School of Medicine, Medical Experimental Education and Research Center. METHODS: Radiofrequency myringotomies were performed under general anesthesia on both ears of 20 rabbits. Mitomycin C (0.3 mg/ml) pledgets were applied in the right ears (study group) and saline pledgets in the left ears (control group). Animals were monitored using otomicroscopy weekly until myringotomy closure. Kaplan-Meier survival techniques were used to compare myringotomy patency time between the two sides. INTERVENTION: Radiofrequency myringotomy under general anesthesia on both ears of 20 rabbits. MAIN OUTCOME MEASURE: Myringotomy patency time. RESULTS: The mean patency time of the study group was 5.45 weeks (95% confidence interval, 5.185-5.715 weeks). The mean patency rate for the control side was 1.60 weeks (95% confidence interval, 1.38-1.82 weeks). The Breslow (generalized Wilcoxon) test showed the study group to have significantly longer patency of radiofrequency myringotomy than the control group (p<0.0001). CONCLUSION: The patency period of radiofrequency myringotomy was not long enough to be proposed as an alternative to the insertion of ventilation tubes, although mitomycin C had a significant adjunct effect in prolonging the patency rate of radiofrequency myringotomy on rabbits.

OBJECTIVE: To assess parameters related to ligasure tonsillectomy (LT) versus cold knife tonsillectomy (CKT) procedure. STUDY DESIGN: Prospective randomized study. METHODS: A prospective study was conducted on 200 consecutive adult patients undergoing tonsillectomy. Indications included chronic tonsillitis and obstructive sleep apnea syndrome. Patients undergoing adenoidectomy, or any procedure together with tonsillectomy, and patients with peritonsillar abscess history or bleeding disorders were excluded. Patients were randomly assigned to either the LT or CKT group. Intraoperative bleeding, operative time, postoperative pain using a visual analogue scale, and complication rates were evaluated. RESULTS: The LT and CDT groups consisted of 108 and 92 individuals, respectively. In the LT group, there was no measurable intraoperative bleeding, whereas mean bleeding for CKT group was 125 mL. The mean operative time was 15 +/- 1.43 minutes for the LT group and 21 +/- 1.09 minutes for the CKT group (P < .001). The overall mean pain score for the LT group was 3.63, whereas for the CKT group it was 5.09 (P < .001). Primary hemorrhage occurred in one subject of the CKT group. Secondary postoperative hemorrhage was noticed two subjects of the LT group and two subjects of the CKT group. In 21 subjects of the LT group, limited peritonsillar edema was noticed. No other complication occurred in both groups. CONCLUSION: LT procedure provides sufficient hemostasis, lower postoperative pain, and reduced operative time, as well as safety against Creutzfeld Jakob disease transmission.

OBJECTIVE: To assess the long-term efficacy of canalith repositioning procedure (CRP) in the treatment of patients with benign paroxysmal positional vertigo (BPPV). BACKGROUND: Alternative theories for the pathophysiology of BPPV have been redefined in the past few years. CRP is considered to be the standard technique for its management. However, long-term follow-up results have been minimally reported in the literature. PATIENTS/METHODS: Five hundred ninety-two patients, 290 (49%) men and 302 (51%) women, were enrolled in this prospective study; their ages ranged from 18 to 84 (mean 59) years. At the time of their first examination, patients reported the duration of symptoms varied from 1 day to 18 months. Inclusion criteria were patient history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). A variant of Epley and Barbeque maneuver was used. The Epley maneuver was used for posterior and anterior canal involvement, and "Barbeque roll" was used for horizontal canal involvement. Short-term follow-up was obtained 48 hours and 7 days after initial treatment, whereas long-term follow-up was obtained at repeated 6 month intervals. RESULTS: The posterior semicircular canal was involved in 521 (88%) patients treated, whereas the horizontal and anterior semicircular canals were involved in 59 (10%) and 12 (2%) patients, respectively. Symptoms subsided immediately in 497 (84%) patients. In 77 (13%) patients, the Dix-Hallpike maneuver remained positive after 48 hours, and CRP was performed again. Patients' mean follow-up was 46 months; 544 (92%) of 592 patients treated reported no symptoms of vertigo. CONCLUSION: Our data, based on long-term follow-up, suggest that CRP remains an efficient and long-lasting noninvasive treatment for BPPV.

OBJECTIVES: To evaluate the role of Ligasure Vessel Sealing System (LVSS) (Valleylab, Boulder, CO) in thyroid surgery, with emphasis given to the duration of the procedure, as well as potential relevant postoperative complications. STUDY DESIGN AND SETTINGS: A prospective study was conducted from November 1, 2002 to October 31, 2003, on patients undergoing thyroid surgery with the use of LVSS device as the primary means of ligation. All patients' records were placed in a database. Efficacy of hemostasis, operation time, and postoperative complications were assessed. RESULTS: were compared with previous surgical procedures done by our team when the LVSS was not available. RESULTS: LVSS proved effective in providing ligation and hemostasis during thyroid surgery in 72 consecutive patients. There was a mean reduction in operating time of 23 minutes compared with previous surgical thyroid procedures. Transient hypocalcaemia occurred in 4 subjects (5.55%); one incidence of transient paresis of the recurrent laryngeal nerve was also observed. CONCLUSION: LVSS proved quite a reliable and safe device in thyroid surgery; it provided sufficient hemostasis and reducing operative time.

OBJECTIVES: To evaluate prognostic factors related with cure rate, in pediatric patients with serous otitis media treated with laser-assisted tympanostomy without ventilation tubes, in a single institution. PATIENTS AND METHOD: The procedure was performed on 124 ears in 88 individuals, from 3 to 14 years old. External auditory canal anatomy, type of anesthesia, tympanic membrane and middle ear fluid characteristics, myringotomy size, and laser parameters, in relation to cure rate, were accordingly studied. RESULTS: The overall cure rate by ear at the end of the 2-month follow-up period was 54.83%, whereas 45.17% still suffered from otitis media. Multivariate statistical analysis demonstrated that the presence of a thick tympanic membrane is significantly correlated with pure outcome in children with serous otitis media, when laser-assisted tympanostomy without ventilation tubes is performed favoring a worse cure rate (P < 0.023). Other parameters did not statistically correlate with the outcome. A 41% parental dissatisfaction rate was noticed. CONCLUSION: This study addresses selection bias for children with serous otitis media, candidates for laser-assisted tympanostomy. These are related to the duration of serous otitis media, the condition of middle ear mucosa, the thickness of the tympanic membrane, the type of anesthesia, and the cost of laser apparatus. There is likely to be a causal relationship between outcome and tympanic membrane appearance in children undergoing laser-assisted tympanostomy.
