Persistent COVID-19 parosmia and olfactory loss post olfactory training: randomized clinical trial comparing central and peripheral-acting therapeutics.

PURPOSE: Although COVID-19 anosmia is often transient, patients with persistent olfactory dysfunction (pOD) can experience refractory parosmia and diminished smell. This study evaluated four putative therapies for parosmia in patients with chronic COVID-19 olfactory impairment. METHODS: After screening nasal endoscopy, 85 patients (49 female, 58%) with pOD and treatment-refractory parosmia were randomized to: (1) ultramicronized palmitoylethanolamide and luteolin + olfactory training (OT) (umPEALUT group, n = 17), (2) alpha-lipoic acid + OT (ALA group, n = 21), (3) umPEALUT + ALA + OT (combination group, n = 28), or 4) olfactory training (OT) alone (control group, n = 23). Olfactory function was assessed at baseline (T0) and 6 months (T1) using a parosmia questionnaire and Sniffin' Sticks test of odor threshold, detection, and identification (TDI). Analyses included one-way ANOVA for numeric data and Chi-Square analyses for nominal data on parosmia. RESULTS: The umPEALUT group had the largest improvement in TDI scores (21.8 ± 9.4 to 29.7 ± 7.5) followed by the combination group (19.6 ± 6.29 to 27.5 ± 2.7), both p < 0.01. The control and ALA groups had no significant change. Patients in the combination and umPEALUT groups had significantly improved TDI scores compared to ALA and control groups (p < 0.001). Rates of parosmia resolution after 6 months were reported at 96% for combination, 65% for control, 53% for umPEALUT and 29% for ALA (p < 0.001). All treatment regimens were well-tolerated. CONCLUSIONS: umPEALUT and OT, with or without ALA, was associated with improvement in TDI scores and parosmia, whereas OT alone or OT with ALA were associated with little benefit.

Modified Valente Technique for Cauliflower Ear: Outcomes in Children at Two-Year Follow-Up : New Surgical Technique for Cauliflower Ear.

BACKGROUND: Cauliflower ear deformity, a common sequela of auricular trauma, presents an esthetic and reconstructive challenge. Existing surgical techniques have limitations, including complexity, donor site morbidity, and variable long-term outcomes. MATERIALS AND METHODS: In this case series, we present a novel and minimally invasive surgical approach for the correction of cauliflower ear deformity that adapts the Valente otoplasty technique; it combines cartilage debulking with helical rim release and Mustardé mattress stitches to restore ear contour and reduce the risk of recurrence. The procedural steps include bielliptic post-auricular skin and soft tissue incision, release of the cartilaginous spring, removal of excess fibrocartilaginous tissue, cartilage reshaping with suture to restore contour, and tissue redistribution to promote adherence of skin to the cartilage framework. RESULTS: Outcomes were evaluated in 7 patients (9 ears) with cauliflower ear deformity, assessing surgical duration, complications, patient satisfaction, and esthetic outcomes at two years after surgery. The mean surgical duration per patient was 52 ± 17 minutes, including 2 bilateral procedures. Follow-up at 24 months showed favorable esthetic outcome in all patients with sustained improvements in auricular contour and symmetry with neither loss of the shape nor recurrence of deformity. Patients reported high satisfaction and improved quality of life, with mean Glasgow Children Benefit Questionnaire scores of 99.3 ± 6.3. CONCLUSIONS: This technique thus demonstrated lasting correction of cauliflower ear with favorable cosmetic outcomes, low risk of complications, and high patient satisfaction. Further investigations and longer-term follow-up are warranted to validate the technique's durability and expand its application to older and more diverse patient populations.

Longitudinal randomized study to evaluate the long-term outcome of endoscopic primary dacryocystorhinostomy with or without silicone tube.

OBJECTIVE: Dacryocystorhinostomy (DCR) is indicated for the treatment of nasolacrimal obstruction with some authors suggesting the use of a silicone tube (stent) to maintain rhinostomy patency a long time. This study aims at comparing the results of endoscopic-DCR (En-DCR) with and without silicone stenting. METHODS: A randomized prospective study was conducted from January 2013 to January 2018, following patients for up to 72 months. Sixty outbound patients suffering from chronic epiphora for primary acquired nasolacrimal duct obstruction were simply randomized and assigned to En-DCR with "silicone stent tube" (SST) or "no silicone stent tube" (NSST) group. Data about the results of the two procedures were collected using Munk' and Ali' assessments. The results were statistically compared to evaluate the differences. RESULTS: 30 patients were in the SST group and 30 in NSST. In the SST group, the tube remained in place for 3-6 months (4.1 ± 1.2 months). The follow-up period was 12-72 months (48.3 ± 6.2 months). Success rates (Junk and Javed Ali assessments) were, respectively, 97% in SST and 90% NSST group, with no statistical difference (Student's test). On a long-term follow-up, SST patients had an increased risk of re-stenosis by 14 months. CONCLUSIONS: Our results showed there were not benefit in using tube, in the opposite it increased risk of re-stenosis. Despite preliminary results, our data confirmed comparing the two methods that silicone tube should not be used.

Endoscopic "Quick" Septoplasty in Preservation Rhinoplasty.

BACKGROUND: Preservation rhinoplasty (PR) is revolutionizing rhinoplasty surgery, based on new anatomical studies, advanced tip suture techniques, and refinement of surgical techniques. Septal surgery is a fundamental preparatory stage during PR, especially for the dorsal preservation let/push-down procedure. To increase the predictability of the septoplasty aesthetic effects on the nasal dorsum and further extend the principles of PR to septal surgery, we applied the endoscopic technology to the "quick" septoplasty technique we had already developed in the past decades. METHODS: One hundred sixty-six patients (41 males, 125 females; mean age, 39.7 years; age range, 18-61 years) were submitted to endoscopic "quick" septoplasty for septal deviation during PR procedure. Preoperative evaluation of the nasal dorsum included external examinations of the size, shape, and orientation of the dorsum. Anterior active rhinomanometry was performed in all patients to determine nasal flow resistance preoperatively and 6 months after surgery. Preoperative and postoperative patients' scores on the Nasal Obstruction Septoplasty Effectiveness questionnaire were compared to assess the improvement of nasal symptoms after surgery. The duration of the septoplasty procedure was measured for all the patients. Standard nasal photographic assessment was performed before and 6 months after surgery. RESULTS: Postoperatively, 98.8% of our patients displayed an improvement of their nasal breathing function. No complication in terms of septal perforation, nasal infection, or bleeding was noticed. No case of turbinoseptal synechiae or cerebrospinal fluid leak was recorded. The dorsum preservation rhinoplasty procedure was successfully completed in all patients. The mean septoplasty operative time, excluding local anesthesia injection and other surgical procedures associated with septal surgery such as turbinoplasty and rhinoplasty, was 11.41 ± 6.23 minutes (range, 9-31 minutes). CONCLUSIONS: Our results show that a short surgical time is needed to perform the proposed endoscopic septoplasty procedure. Such a short operative time allows the physician to both correct septal deviations quickly and correct/reduce the cartilaginous hump, thus representing a fundamental element of PR. In addition, the minimal tissue dissection reduces intraoperative nasal edema, favoring intraoperative aesthetic evaluation.

Cochlear implantation in children with "CHARGE syndrome": surgical options and outcomes.

CHARGE syndrome is a rare, polymalformative disease, representing one of the major causes of associated blindness and deafness. Bilateral, severe-profound, sensorineural hearing loss is common in CHARGE children. Aim of this study is to present our results in children with "CHARGE syndrome" submitted to cochlear implantation (CI). The frequency of anatomic anomalies, possible variations in the surgical technique of CI, and the audiological/rehabilitative benefits attained in our patients are reported. we submitted 5 children affected by CHARGE syndrome with profound, bilateral, sensorineural hearing loss to CI. Otoacoustic emissions, auditory brainstem response, acoustic impedance testing, cranial computed tomography and magnetic resonance were carried out preoperatively in all children. CI was performed using the mastoidotomy-posterior tympanotomy approach in two cases, and the suprameatal approach in three children. Infant toddler-meaningful auditory integration scale was used to evaluate kid's audiological performance before and after CI. Intra-operatory findings and postsurgical complications were evaluated. Among our patients, intraoperative anatomical malformations were cochlear hypoplasia (100 %), ossicles malformations (100 %), semicircular canals aplasia (100 %), oval window atresia (60 %), round window atresia (40 %), widening of the aqueduct of the vestibule (20 %), and aberrant course of the facial nerve (20 %). No intra- or postoperative complication was recorded in relation to implant positioning. After a follow-up ranging from 1 to 4.5 years, only 2/5 patients used oral language as the sole mean of communication, 1 started utilizing oral language as the main mean of communication, while 2 patients did not develop any linguistic ability. In conclusion, CI in patients with CHARGE association is feasible and, despite results variability, it should be carried out in CHARGE children with severe hearing loss as soon as possible. Although the selection of a specific surgical technique does not seem to influence the audiological outcome, the suprameatal access is valuable when important surgical landmarks (i.e. lateral semicircular canal and incus) are absent.

Spreader graft in closed rhinoplasty: the "rail spreader".

Spreader grafts (SGs) have been widely used for both aesthetic and functional reasons to prevent middle vault collapse and treat internal nasal valve insufficiency. Although SG precise fixation can be easily achieved in open rhinoplasty, the difficulties of SG placement in closed rhinoplasties can be discouraging. In the present report, we describe a new custom-made SG (called "rail spreader") and the personal easy method of application of such graft in "endonasal" rhinoplasty. The technical details and results are reported along with the advantages of our technique over previously described approaches.

A Supplement with Ribes Nigrum, Boswellia Serrata, Bromelain and Vitamin D to Stop Local Inflammation in Chronic Sinusitis: A Case-Control Study.

Although chronic sinusitis widely affects the adult population, the treatments currently used did not always satisfactorily solve the symptoms. Traditional therapy with steroids and antibiotics presents risks and benefits and the new drugs, i.e., monoclonal antibody, are valid solutions despite being quite expensive. Natural molecules could be a valid treatment that combines good efficacy and low price. We conducted a case -control study to evaluate the benefit of an oral supplement with Ribes nigrum, Boswellia serrata, Bromelain and Vitamin D on chronic sinusitis symptoms. 60 patients were randomly assigned to one of the three groups: control using nasal steroids only, treatment 1 using nasal steroid and 1 dose of the oral supplement for 30 days and treatment 2 in which patients used nasal steroid and two oral supplement doses daily for 15 days. Conditions of the nasal mucosa and a blood sample (WBC, IgE and CRP) were analyzed at T0, T1 (15 days after treatment) and T2 (30 days after treatment. Patients treated with the supplement improved their nasal findings (hyperemia of mucosa and rhinorrhea) with statistically significant differences from the control. Our preliminary data suggest that the addition of supplement containing Ribes nigrum, Boswellia serrata, Vitamin D and Bromelain to the traditional local therapy (nasal spray with cortisone) can be a supporting therapy to modulate the local inflammation in the nose in patients affected by chronic sinusitis.

Single-incision robot-assisted transaxillary surgery for early-stage papillary thyroid cancer.

OBJECTIVES: We describe the surgical details, results, and learning curve of a proposed technique for single-incision transaxillary robot-assisted thyroid surgery for early-stage thyroid cancer. METHODS: We performed single-incision transaxillary robot-assisted total thyroidectomy with the da Vinci surgical system in 29 patients (5 male, 24 female; median age, 45 years; age range, 19 to 69 years) with papillary thyroid cancer (cT1 NO) using our proposed technique with selected instrumentation. Preoperative ultrasound examination, fine-needle aspiration cytology, and contrast computed tomographic scanning were performed in all subjects. Ultrasound examination was carried out 1 month after surgery to assess the amount of residual thyroid tissue. RESULTS: No procedure was converted to conventional open surgery. The mean total operation time was 178.51 +/- 24.18 minutes, and the mean console time was 126.10 +/- 14.47 minutes. A progressive reduction of console time was noted (160 minutes for the first procedure versus 102 minutes for the last one). No cases of permanent hypocalcemia, recurrent laryngeal nerve palsy, or postoperative bleeding occurred. The mean amount of postoperative residual thyroid tissue on ultrasound examination was 8.93 +/- 2.15 mm. CONCLUSIONS: The single-incision transaxillary robot-assisted total thyroidectomy we propose is a feasible and relatively safe procedure in selected patients with early-stage thyroid cancer.

Covid-19 negatively impacted on small oncology surgery but none on major procedures: Regional experience.

AIM: To understand the impact of COVID pandemic on the activity and patients' care of the Head and Neck regional Unit, temporary moved in a COVID-free hospital. METHODS: We retrospectively analyzed the yearly activity of the "Head & Neck Cancer Unit" at the Azienda Ospedali Riuniti Marche Nord (Italy) during 2020 (COVID-19 pandemic) and we compared it with the one performed in 2019. Statistical analyses were performed using Chi-square. RESULTS: No significant differences were observed comparing the total number of patients treated for H&N squamous cell carcinoma (SCC) in 2019 with the ones in 2020. Moreover, no differences were identified in term of cancer stage at the moment of the surgery between 2019 and 2020. On the contrary, a significant reduction in the number of surgical procedures carried out for thyroid (p < 0.05) and skin (p < 0.001) malignancies was identified. CONCLUSIONS: Despite Covid-19 limitations, our institution was able to preserve the number of major oncologic procedures without negative impact on patients' care. We believe that the creation of specific COVID-free hospital can be the key preserve quality of care in epidemic emergency.

Olfactory Dysfunction, Headache, and Mental Clouding in Adults with Long-COVID-19: What Is the Link between Cognition and Olfaction? A Cross-Sectional Study.

Smell alteration and cognitive impairment are common features of the Long-COVID Syndrome. Mental clouding, often described as brain fog, might affect smell by altering recollection of odors or through a share mechanism of neuroinflammation. We investigated mental clouding, headache, and cognitive function in adult patients with persistent COVID-19 olfactory dysfunction. This multi-center cross-sectional study enrolled 152 adults with self-reported olfactory dysfunction from 3 tertiary centers specialized in COVID-19 olfactory disorders. Inclusion criteria were smell alterations after COVID-19 persisting over 6 months from infection, age >18 and < 65. Exclusion criteria included smell alterations, headache, or memory problems prior to COVID-19 infection. The patients were evaluated by olfactometry, nasal endoscopy, headache scale, cognitive assessment, Mini Mental State Examination (MMSE), and self-reported measures. Smell dysfunction was stratified and classified based on olfactory deficit severity and presence of olfactory distortion (parosmia, cacosmia). Data on smell disorder, mental clouding, MMSE, and headache were analyzed to assess correlations. Among the 152 patients studied, 50 (32.8%) presented with anosmia, 25 (16.4%) with hyposmia, 10 (6.6%) with parosmia/cacosmia, and 58 patients (38.2%) with a combination of hyposmia and parosmia; seven (4.6%) patients suffered from headache exclusively, and two (1.4%) had headache and mental clouding as their primary symptom. Headache was reported by 76 (50%) patients, and mental clouding by 71 (46.7%). The patients reporting headache, mental clouding, or both, had significantly increased risk of suffering from anosmia and/or hyposmia when compared with their counterparts without these neurological symptoms. No patients had reduced MMSE scores. In our cohort of adult patients with post-COVID-19, smell alterations persisting over 6 months, cognitive impairment and headache were associated with more severe olfactory loss, consistent with neuroinflammatory mechanisms mediating a variety of Long-COVID symptoms.

Single-Center-Single-Blinded Clinical Trial to Evaluate the Efficacy of a Nutraceutical Containing Boswellia Serrata, Bromelain, Zinc, Magnesium, Honey, Tyndallized Lactobacillus Acidophilus and Casei to Fight Upper Respiratory Tract Infection and Otitis Media.

Some nutraceuticals have been studied as supportive treatment for fighting upper respiratory tract infection and middle ear disease. Our study aims at evaluating the effect of a specific oral supplementation in the treatment of pediatric otits media. The subjects were randomly assigned by the physician (single-blinded study) to one of three groups: Control Group (CG), Treatment Group 1 (TG1), or Treatment Group 2 (TG2). Both TG were treated with Flogostop Duo (for 20 days-TG1 or 30 days-TG2) in combination with the standard treatment, while CG underwent standard treatment only. The standard treatment was nasal aerosol with Fluticasone and Mucolytic, and nasal washing with hypertonic solution. All patients were analyzed by otoscopy, impedance, fibroscopy, and pure auditory test at the baseline (T0), after 20 days (T1) and 35 days (T2). 120 children were included in the study, 40 in the CG, 40 in the TG1, and 40 in the TG2. Both TG1 and TG2 presented statistically significant differences with respect to controls in otoscopy, impedance, fibroscopy, and PTA at T2. The otoscopy improved at T2 with statistically significant value only in TG2. The impedance and fibroscopy improved at T1 both in TG1 and TG2 compared to CG. A statistically significant improvement was observed in TG2 at T2 in comparison to both CG and TG1. Statistically significant differences were observed in PTA at T2 only compared with controls. This study confirmed the efficacy of nutraceutical as supporting therapy in the upper respiratory tract infection in children. In particular, the supplement containing Boswellia serrata and Bromelain, which are molecules with strong anti-inflammatory and pain-control capacities, could add the benefit without the adverse effects which are related to NSAID use.

Use of Nutraceuticals in Elderly to Fight Inflammation and Immuno-Senescence: A Randomized Case-Control Study.

Elderly people are at high risk of suffering from infection and being affected by severe forms of disease because their immunosystem suffers from aging. The alteration of normal immune functions causes the increase of pro-inflammatory cytokines which can expose these people to increased risk of developing pathologies as cancer, diabetes, and/or arthritis. Some supplements could be helpful for restoring normal immune functions. We conducted a case-control study to evaluate the efficacy of a supplement containing Sambucus nigra, zinc, tyndallized Lactobacillus acidophilus (HA122), arabinogalactans, vitamin D, vitamin E, and vitamin C to improve the inflammatory levels (IL-6 and CRP) and to modulate the lymphocytes growth. Additionally, we analyzed wellness by self-questionnaire. This study had two control group: a young group and an elderly one. Our study showed that treating elderly patients with the supplement for 30 days improved IL-6, CRP, and lymphocytes levels; the result was independent from the dosage of the supplements used. Elderly patients, despite the improvement, were not able to reach the same conditions of young patients; however, most of the patients (>70%) claimed to "feel better" after the use of the supplement. The use of this supplement should be considered at a low dosage for a prolonged period to reduce inflammation and modulate immune senescence in patients over 60 years old.

Ultramicronized Palmitoylethanolamide and Luteolin Supplement Combined with Olfactory Training to Treat Post-COVID-19 Olfactory Impairment: A Multi-Center Double-Blinded Randomized Placebo- Controlled Clinical Trial.

BACKGROUND: Olfactory training is the only evidence-based treatment for post-viral olfactory dysfunction. Smell disorders after SARS-CoV-2 infection have been attributed to neuroinflammatory events within the olfactory bulb and the central nervous system. Therefore, targeting neuroinflammation is one potential strategy for promoting recovery from post-COVID-19 chronic olfactory dysfunction. Palmitoylethanolamide and luteolin (PEA-LUT) are candidate antiinflammatory/ neuroprotective agents. OBJECTIVE: To investigate recovery of olfactory function in patients treated with PEA-LUT oral supplements plus olfactory training versus olfactory training plus placebo. METHODS: Multicenter double-blinded randomized placebo-controlled clinical trial was held. Eligible subjects had prior COVID-19 and persistent olfactory impairment >6 months after follow-up SARS-CoV-2 negative testing, without prior history of olfactory dysfunction or other sinonasal disorders. Participants were randomized to daily oral supplementation with ultramicronized PEA-LUT 770 mg plus olfactory training (intervention group) or olfactory training with placebo (control). Sniffin' Sticks assessments were used to test the patients at baseline and 90 days. RESULTS: A total of 185 patients, including intervention (130) and control (55) were enrolled. The intervention group showed significantly greater improvement in olfactory threshold, discrimination, and identification scores compared to controls (p=0.0001). Overall, 92% of patients in the intervention group improved versus 42% of controls. Magnitude of recovery was significantly greater in the intervention group versus control (12.8 + 8.2 versus mean 3.2 + 3), with >10-fold higher prevalence of anosmia in control versus intervention groups at the 90-day endpoint. CONCLUSION: Among individuals with olfactory dysfunction post-COVID-19, combining PEA-LUT with olfactory training resulted in greater recovery of smell than olfactory training alone.

Misinterpretation of head and neck masses can delay the correct diagnosis. A two-step demolitive-reconstruction surgery for saving patient's life.

OBJECTIVE: To present a rare case of sebaceous cyst masking skin squamous carcinoma. The delayed diagnosis made necessary a two-step (demolition and reconstruction) surgery to save patient's life. MATERIAL AND METHODS: A 77-year-old male, suffering from persistent right hemicrania and eye pain referred to different specialists, who misinterpreted his symptoms. The man presented on the right zygomatic area a big sebaceous cyst which masked a squamous cells carcinoma (SCC) infiltrating the surrounding structures including the orbito zygomatic complex and the orbital content that was the cause of the symptoms. Patient underwent biopsy, CT thorax and MRI of the head and neck as pre-operative examinations. A two-step surgery was performed to remove the tumor. RESULTS: The skin biopsy showed the presence of sun damaged skin contains moderately differentiated invasive SCC within the context of sebaceous cyst. While the CT chest was negative, the head and neck MRI showed a huge tumor invading the orbit and periorbital tissue, the zygomatic bone and the soft tissues up to the posterior orbital area, without presence of neck lymph nodes. Le lesion has been classified as cT4 N0 M0 (TNM 8) and a two-step surgery approach (demolition and reconstruction) was performed with successful results at 1 year-follow up. CONCLUSIONS: The delayed diagnosis of SCC was due to the misdiagnosis of the signs of the tumor invasion. Demolitive and reconstructive surgeries allowed to preserve patient's life. The careful attention to patient's skin characteristic, the analysis of general and local clinical signs (irradiated pain, cyst and skin type) and the evaluation of the complex differential diagnosis could be the key to avoid delayed treatment in head and neck cancer.

Quick septoplasty in children: Long-term effects on nasal breathing and dentofacial morphology. A prospective cephalometric study.

OBJECTIVE: Many authors have investigated the most appropriate surgical approach to the deviated septum in childhood, considering the obligate mouth-breathing habit a possible cause of malocclusion and disharmonious development of the facial skeleton in growing kids. Nevertheless, controversies still remain about the long-term functional/esthetic results of such procedures, mainly due to the duration of the follow-up and possible confounding factors. METHODS: 111 Caucasian children (age range: 6-13 years) were submitted to a personal "Quick" septoplasty surgical technique between 2005 and 2010. Preoperative otorhinolaryngological examination using flexible nasal endoscopy, anterior active rhinomanometry (AAR), Nasal Obstruction Septoplasty Effectiveness (NOSE) questionnaire, and dentofacial evaluation (including cephalometry) were performed. Postoperative AAR, NOSE questionnaire and cephalometric assessment were carried out in all patients at the age of 18 years. Informed consent was obtained from children's parents as appropriate. RESULTS: No surgical complication was recorded. Among our patients, a significant (p <0.001) improvement of nasal breathing resistances at AAR and NOSE questionnaire scores was found after surgery. A significant improvement in cephalometric/dental parameters (gonial angle values, anterior facial height, prevalence of class I occlusion, maxillary intermolar width, and cross-bite frequency) was noticed after the follow-up with respect to preoperative conditions. CONCLUSION: The "Quick" septoplasty technique described is a practical and conservative procedure with a low complication rate that offers long-term favourable results for the correction of nasal septum deviations in children. Nasal-breathing restoration may favor a physiological and harmonious development of craniofacial and dental structures in offspring.

Metastatic signet ring cell gastric carcinoma bypassing Virchow's node: An unexpected etiology of a painful neck mass.

Metastatic lymph nodes of the head and neck are often associated with locoregional spread of mucosal squamous carcinoma, but in rare instances visceral malignancies may bypass Virchow's node. The possibility of distant metastasis should be considered.

Airway obstruction from tracheostomy balloon cuff herniation during oral cancer removal. Emergency successfully managed and lessons learnt from device malfunction.

OBJECTIVE: Tracheostomy tube cuff balloon herniation is a rare event and can determine airway obstruction. Sometimes the obstruction is not very evident but, if it is not correctly solved, can determine a severe hypoxia with patient's death. MATERIAL AND METHODS: We present a 49-year-old male patient, with cT4aN0M0 squamous cell carcinoma of the oral cavity, who was admitted to the hospital for definitive surgical resection. Due to mass an endo-oral intubation was not possible, so a surgical tracheotomy was performed. General anaesthesia was induced with Propofol (2 mg/kg) and Fentanil (1 mcg/kg) without gas. Surgery commenced via a trans-oral and trans-cervical approach, but it was halted after approximately 2 min as oximetry demonstrated a progressive fall from 98% to 78%. After confirmation of correct function of anaesthetic devices, the endotracheal cannula was tested; although surgeon deflated the tube cuff, repositioned the tube, and re-inflated the cuff, oxygen saturation did not change. So, the cannula was changed and patient's saturation increased up to normal value. RESULTS: The balloon cuff of the cannula showed a herniation, responsible of insufficient ventilation. CONCLUSIONS: Cuff herniation should be considered in case of unexpected airway obstruction, and a systematic, rapid approach to investigation and management should ensure timely identification and correction.

Olfactory Dysfunction in COVID-19 Patients: Prevalence and Prognosis for Recovering Sense of Smell.

While olfactory dysfunction associated with coronavirus disease 2019 (COVID-19) has attracted considerable interest, few studies have tracked outcomes at serial time points or beyond 2 weeks. Furthermore, data are conflicting regarding whether COVID-19 severity correlates with degree of olfactory dysfunction. This prospective case-control study analyzed prevalence and severity of subjective loss of smell in outpatients (n = 23) and inpatients (n = 20) with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection vs healthy controls (n = 25). Olfactory dysfunction was reported more commonly in COVID-19 patients than in healthy controls (P < .001), and outpatients paradoxically reported loss of smell more commonly than inpatients (P = .02). Headaches were present in 52% of patients with olfactory dysfunction. Anosmia or hyposmia persisted beyond 5 days but most of the patients recovered by 30 days, suggesting favorable prognosis for olfaction. Differences between inpatients and outpatients are potentially reflective of timeline of olfactory symptoms and contextual factors, underscoring the importance of corroborative objective testing, coupled with careful tracking of temporal relationships.

COVID-19 in the tonsillectomised population.

OBJECTIVE: Interactions between SARS-CoV-2 and pharyngeal associated lymphoid tissue are thought to influence the manifestations of COVID-19. We aimed to determine whether a previous history of tonsillectomy, as a surrogate indicator of a dysfunctional pharyngeal associated lymphoid tissue, could predict the presentation and course of COVID-19. METHODS: Multicentric cross-sectional observational study involving seven hospitals in Northern and Central Italy. Data on the clinical course and signs and symptoms of the infection were collected from 779 adults who tested positive for SARS-CoV-2, and analysed in relation to previous tonsillectomy, together with demographic and anamnestic data. RESULTS: Patients with previous tonsillectomy showed a greater risk of fever, temperature higher than 39°C, chills and malaise. No significant differences in hospital admissions were found. CONCLUSIONS: A previous history of tonsillectomy, as a surrogate indicator of immunological dysfunction of the pharyngeal associated lymphoid tissue, could predict a more intense systemic manifestation of COVID-19. These results could provide a simple clinical marker to discriminate suspected carriers and to delineate more precise prognostic models.
