Medullary Thyroid Carcinomas Classified According to the International Medullary Carcinoma Grading System and a Surveillance, Epidemiology, and End Results-Based Metastatic Risk Score: A Correlation With Genetic Profile and Angioinvasion.

Due to the lack of a standardized tool for risk-based stratification, the International Medullary Carcinoma Grading System (IMTCGS) has been proposed for medullary thyroid carcinomas (MTCs) based on necrosis, mitosis, and Ki67. Similarly, a risk stratification study using the Surveillance, Epidemiology, and End Results (SEER) database highlighted significant differences in MTCs in terms of clinical-pathological variables. We aimed to validate both the IMTCGS and SEER-based risk table on 66 MTC cases, with special attention to angioinvasion and the genetic profile. We found a significant association between the IMTCGS and survival because patients classified as high-grade had a lower event-free survival probability. Angioinvasion was also found to be significantly correlated with metastasis and death. Applying the SEER-based risk table, patients classified either as intermediate- or high-risk had a lower survival rate than low-risk patients. In addition, high-grade IMTCGS cases had a higher average SEER-based risk score than low-grade cases. Moreover, when we explored angioinvasion in correlation with the SEER-based risk table, patients with angioinvasion had a higher average SEER-based score than patients without angioinvasion. Deep sequencing analysis found that 10 out of 20 genes frequently mutated in MTCs belonged to a specific functional class, namely chromatin organization, and function, which may be responsible for the MTC heterogeneity. In addition, the genetic signature identified 3 main clusters; cases belonging to cluster II displayed a significantly higher number of mutations and higher tumor mutational burden, suggesting increased genetic instability, but cluster I was associated with the highest number of negative events. In conclusion, we confirmed the prognostic performance of the IMTCGS and SEER-based risk score, showing that patients classified as high-grade had a lower event-free survival probability. We also underline that angioinvasion has a significant prognostic role, which has not been incorporated in previous risk scores.

Is it possible to diagnose Posterior Semicircular Canal BPPV from the sitting position? The role of the Head Pitch Test and the upright tests along the RALP and LARP planes.

PURPOSE: The diagnosis of benign paroxysmal positional vertigo (BPPV) involving the posterior semicircular canal (PSC) is traditionally entrusted to positioning tests where patients are rapidly brought in the supine position. This prospective study aims to define the role of a diagnostic protocol for PSC-BPPV including only upright tests. MATERIALS AND METHODS: 109 patients with PSC-BPPV were enrolled. The Head Pitch Test (HPT) was carried out first. If uneventful, the patient's head was turned 45° to each side and bent back-and-forth along the plane aligning either with the right anterior-left posterior (RALP) or left anterior-right posterior (LARP) canals, thus performing the upright RALP / upright LARP (uRALP/uLARP) test. Nystagmus observed was used to predict the diagnosis, which was therefore confirmed by Dix-Hallpike tests. RESULTS: PSC-BPPV could be correctly diagnosed in 75.2% of cases with the sole HPT and in 87.2% of cases by adding the uRALP/uLARP test (Upright Protocol). The time elapsed from symptoms onset was closely related to the protocol sensitivity, as it reached 100% (64/64) in acute patients while decreased to 68.9% (31/45) in cases evaluated after 7 days (p < 0.001). CONCLUSIONS: Upright maneuvers could correctly diagnose PSC-BPPV in most cases. uRALP/uLARP test demonstrated to improve the sensitivity of the HPT, mainly in recent-onset BPPV.

Reduction in healthcare services during the COVID-19 pandemic: Patient screening based on symptoms is an effective strategy for avoiding delayed laryngeal cancer diagnosis.

OBJECTIVE: Restriction in healthcare services during the COVID-19 pandemic caused delays in the diagnosis and treatment of several diseases. To overcome the risk of missed diagnosis of head and neck cancers, before deleting the scheduled appointments, we have introduced a selection of the patients by examining the clinical presenting issue and previous medical history. The aim of this study is to show the effects of the abovementioned strategy on the diagnosis and management of laryngeal cancer. METHODS: Data were extracted from the Hospital software regarding the new diagnosis of laryngeal SCC in the periods from March 2020 to December 2020 during the pandemic (study group) and from March 2019 to December 2019 (control group) were collected. Data were compared regarding: TNM stage, time from first medical examination to histological diagnosis (Time-1), and time form histological diagnosis to beginning of treatments (Time-2). RESULTS: The final study group was composed by 19 laryngeal cancers, the control group by 25 cases. No significant differences were found in the tumour stage between the groups. In the study group, Time-1 was shorter (24 days versus 43 days, p = 0.012), while Time-2 in surgically-treated patients was longer (20 days versus 9 days, p = 0.012). CONCLUSION: During the pandemic, there was a dramatic lack of medical and nurse staff needed for surgical procedures. As consequence, the time between the diagnosis of malignancy and surgical treatment increased. In our unit, an efficient patient selection strategy to reschedule medical appointments avoided a dangerous shift toward higher laryngeal cancer stages.

Pneumolabyrinth: a systematic review.

PURPOSE: The aim of this study is to provide a systematic review of the literature about the etiology, clinical and radiological presentation, surgical management, and outcomes of pneumolabyrinth (PNL). METHODS: A systematic review of the literature was performed including studies published up to September 2020 in electronic databases (PubMed/MEDLINE, EMBASE, Cochrane Library, and Scopus). The PRISMA standard was applied to identify English, Italian, or French-language studies mentioning PNL. Full texts lacking information on the etiology were excluded. Data concerning the cause, site of air bubbles/fistula, clinical presentation, treatment, and outcome were collected. A qualitative synthesis of the results was performed. RESULTS: Seventy-eight articles were eventually included; 132 patients were involved in the qualitative synthesis. The most common causes were: stapes surgery (24/132, 18.2%), temporal bone fracture (42/132, 31.8%), head trauma without temporal bone fracture (19/132, 14.4%), penetrating trauma (21/132, 15.9%), and barotrauma (15/132, 11.4%). The site most commonly involved was the vestibule (102/107, 95.3%), followed by cochlea (43/107, 40.2%) and semicircular canals (25/107, 23.4%). CONCLUSION: The etiopathogenesis of PNL can be summarized in traumatic, iatrogenic, or inflammatory/infective. Its management consists in exploratory tympanotomy and sealing the fistula, but also conservative treatments can be attempted. Vestibular symptoms disappear in the majority of cases. Instead, the prognosis of hearing function is widely variable, and complete recovery is less probable. The certainty of evidence is still too low to make it useful for clinical decision-making.

Safe tracheotomy for patients with COVID-19.

Patients affected by severe acute respiratory syndrome coronavirus 2 disease (COVID-19) with respiratory distress may need invasive mechanical ventilation for a long period of time. Head and neck surgeons are becoming increasingly involved in the care of COVID-19 patients because of the rapidly increasing number of tracheotomies required. This procedure, when performed without protection, may lead to the infection of the medical and nursing staff caring for the patient. The aim of this report is to share our protocol for performing a safe surgical tracheotomy in COVID-19 patients. Infection of the nursing/medical staff involved in the first 30 tracheotomies performed in patients affected by COVID-19 in the Intensive Care Unit of a tertiary referral center were evaluated. Mistakes that occurred during surgery were analyzed and discussed. None of the nursing/medical staff presented signs or symptoms of COVID-19 within 15 days after the procedure. Conclusion: The authors have prepared a protocol for performing a safe surgical tracheotomy in patients affected by COVID-19. Surgeons who might be involved in performing the tracheotomies should become familiar with these guidelines.

Cochlear function after type-1 tympanoplasty: endoscopic versus microscopic approach, a comparative study.

PURPOSE: To investigate and compare the effect of endoscopic and microscopic type 1 tympanoplasty on the cochlear function, to determine if they have a different impact on the inner ear function. METHODS: 72 ears treated by transcanal endoscopic type 1 tympanoplasty and 84 ears treated by microscopic type 1 tympanoplasty in 3 tertiary referral centers were enrolled in the study. Microscopic type 1 tympanoplasty were performed by transcanal or retroauricular approach. Only patients with mobile and intact ossicular chain were involved in the study. A retrospective chart review was performed. Main outcome measures were: (1) change in bone conduction thresholds at 250, 500, 1000, 2000, 4000 Hz; (2) change in bone conduction Pure Tone Audiometry; (3) correlation of audiometric outcomes with surgical technique, graft type and graft position. RESULTS: A mild postoperative bone conduction threshold shift was observed at 2000 Hz and 4000 Hz in both groups, without significant differences between the two groups. No statistically significant modifications in bone conduction were observed at any frequencies in patients operated by transcanal endoscopic approach compared with those who underwent transcanal or retroauricular microscopic type 1 tympanoplasty. Moreover, neither the placement nor the type of the graft seemed to influence the cochlear function preservation. CONCLUSIONS: The endoscopic and the microscopic approaches have a similar impact on the bone conduction threshold during type 1 tympanoplasty. In particular, the one-handed manipulation of the ossicular chain during the endoscopic technique did not show an increased risk of inner ear damage.

Endoscopic revision stapes surgery: surgical findings and outcomes.

PURPOSE: Hearing results in revision stapes surgery are largely dependent on the cause of failure, and an appropriate intraoperative diagnosis is crucial for a good outcome. The endoscope allows a detailed exploration of the middle ear cavity and is particularly suitable for the intraoperative assessment of the cause of failure of previous stapes surgery. The present study analyzes the intraoperative findings and outcomes of patients undergoing revision stapes surgery through the endoscopic transcanal approach. METHODS: Surgical videos and charts of patients undergoing endoscopic revision stapes surgery from 2008 to 2017 were reviewed retrospectively. Intraoperative findings, difficulties encountered during the surgery and hearing outcomes were evaluated. The feasibility of each surgical step with the totally endoscopic approach or the need for bimanual manipulation was assessed as well. RESULTS: Thirty-four patients were included in the study. The endoscopic transcanal approach allowed a detailed exploration of the middle ear cavity and an accurate intraoperative diagnosis and management of the different causes of failure of the previous surgery. 89.8% of patients achieved an air-bone gap for the PTA ≤ 20 dBHL and 68.5% a closure of the air-bone gap. CONCLUSIONS: The present study showed that totally endoscopic revision stapes surgery is a feasible, safe and effective procedure. The transcanal endoscopic approach allowed an accurate intraoperative diagnosis without the need for an endaural or retroauricular approach, with the possibility to manage all the possible intraoperative scenarios. A larger series with a longer follow-up is needed to validate the results.

Features Associated With High Risk of Recurrence in Saccular Laryngeal Cysts: A Systematic Review and Qualitative Synthesis.

INTRODUCTION: Saccular cysts are rare benign anomalies of the larynx (1.5% of laryngeal anomalies) determined by dilatation of the laryngeal saccule. They can be congenital or acquired. Clinical manifestation depends on the site of the cyst and the age of the patient. Children frequently have stridor and dyspnea, while adults usually complain of dysphonia.The therapeutic approach can be surgical or nonsurgical (needle aspiration or drainage).However, guidelines on the management of this disease are lacking in the literature.This systematic literature review was conducted through an interferential analysis with the aim of detecting the association between clinical, diagnostic, and operative factors and the recurrence of saccular cysts. MATERIALS AND METHODS: This systematic literature review was evolved following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist statement Papers published up to August 2023 containing relevant clinical data were searched in Embase/PubMed, Web of Science, Scopus, and Cochrane database. Full texts lacking information on the patient's data, clinical, radiological, and/or histological diagnosis of saccular cysts of the larynx were excluded. Articles with follow-up inferior to 6 months and not reporting any treatment of the cyst were excluded, too. Data concerning signs and symptoms, cyst characteristics, and the type of treatment were described, and the risk of recurrence was studied in association with these features. A qualitative synthesis of the results was performed. RESULTS: Ninety-eight articles were screened. One hundred two patients were involved in the analysis. The articles with low or intermediate risk of bias were 22 (8 case reports and 14 case series) and they were included in the statistical analysis. Median age was 25 years (range 0-81). Saccular cysts were congenital (46/102, 45%) of cases acquired (56/102, 55%). Relying on the available data, all patients were symptomatic, with stridor as the main symptom (59%). Surgical approach was performed in 85% of cases, while drainage or needle aspiration of the cyst was the treatment of choice in the remaining 25% of cases. Twenty-four percent of patients had recurrence of the disease within 3 months. Median age at recurrence was 9 years. Cysts characteristics, preoperative management, and type of treatment were associated with an increased risk of disease recurrence (P < 0.05). CONCLUSIONS: Saccular cysts are rare congenital or acquired laryngeal diseases. Data regarding their management and factors associated with the risk of recurrence are still limited. Congenital cysts treated conservatively have a higher risk of recurrence than acquired cysts treated by open surgical techniques or by microlaryngoscopy. A better knowledge of factors associated with a higher risk of recurrence could help choose the best treatment.

Vestibular assessment in sudden sensorineural hearing loss: Role in the prediction of hearing outcome and in the early detection of vascular and hydropic pathomechanisms.

Introduction: Predicting hearing outcome in sudden sensorineural hearing loss (SSNHL) is challenging, as well as detecting the underlying pathomechanisms. SSNHL could be associated with vestibular damage since cochleo-vestibular structures share the same vascularization, along with being in close anatomical proximity. Whereas viral inflammations and autoimmune/vascular disorders most likely represent the involved aetiologies, early-stage Menière's disease (MD) can also present with SSNHL. Since an early treatment could beneficially influence hearing outcome, understanding the possible etiology plays a pivotal role in orienting the most appropriate treatment. We aimed to evaluate the extent of vestibular damage in patients presenting with SSNHL with or without vertigo, investigate the prognostic role of vestibular dysfunctions on hearing recovery and detect specific lesion patterns related to the underlying pathomechanisms. Methods: We prospectively evaluated 86 patients with SSNHL. Audio-vestibular investigation included pure-tone/speech/impedance audiometry, cervical/ocular-VEMPs, vHIT and video-Frenzel examination. White matter lesions (WML) were evaluated on brain-MRI. Patients were followed-up and divided into "SSNHL-no-vertigo," "SSNHL+vertigo" and "MD" subgroups. Results: Hearing was more impaired in "SSNHL+vertigo" patients who exhibited either down-sloping or flat-type audiograms, and was less impaired in "MD" where low frequencies were mostly impaired (p < 0.001). Otolith receptors were more frequently involved than semicircular canals (SCs). Although the "SSNHL-no-vertigo" subgroup exhibited the lowest vestibular impairment (p < 0.001), 52% of patients developed otolith dysfunctions and 72% developed nystagmus. Only "MD" subjects showed anterior SC impairment and upbeating spontaneous/positional nystagmus. They more frequently exhibited cervical-VEMPs frequency tuning (p = 0.036) and ipsilesional spontaneous nystagmus (p < 0.001). "SSNHL+vertigo" subjects presented with more frequently impaired cervical-VEMPs and posterior SC and with higher number of impaired receptors (p < 0.001). They mainly exhibited contralesional spontaneous and vibration-induced nystagmus (p < 0.05) and only they showed the highest WML score and "vascular" lesion patterns (p < 0.001). Concerning the outcomes, hearing was better in "MD" and worse in "SSNHL+vertigo" (p < 0.001). Hearing recovery was mostly affected by cervical-VEMPs impairment and the number of involved receptors (p < 0.05). Patients with "vascular" lesion patterns presented with the highest HL degree and WML score (p ≤ 0.001), while none of them exhibited a complete hearing recovery (p = 0.026). Conclusions: Our data suggest that vestibular evaluation in SSNHL can provide useful information on hearing recovery and underlying aetiologies.

The Audiological Follow-Up of Children with Symptomatic Congenital Cytomegalovirus Infection: An Experience in Two Italian Centers.

BACKGROUND: Congenital cytomegalovirus (cCMV) infection is the leading cause of non-hereditary sensorineural hearing loss in children. While about 10% of children reportedly display symptoms at birth, 85-90% of cCMV infection cases are asymptomatic. However, 10-15% of these asymptomatic infants may later develop hearing, visual, or neurodevelopmental impairments. This study aimed to evaluate the impact of cCMV infection on newborns' hearing function with a particular emphasis on progressive and late-onset cases. METHODS: This study is a retrospective chart analysis with longitudinal character and was conducted in two Italian centers: Center 1 (from 1 November 2007 to 31 December 2021) and Center 2 (from 1 January 2012 to 31 December 2021). Data collected included newborn hearing screening results, characterization of hearing loss (unilateral/bilateral, degree of impairment), and audiological follow-up. RESULTS: The cohort consisted of 103 children (42% males, 58% females). In total, 28 children presented with hearing impairment; 71.4% (20 out of 28) of the cases of hearing loss were severe/profound, with 35.7% of the cases due to unilateral hearing loss. Out of twenty-eight, six experienced progression of hearing loss and four had late-onset hearing loss. CONCLUSIONS: In the absence of universal cCMV screening, hearing screening at birth for cCMV remains a critical factor for early diagnosis. A significant percentage of children affected by cCMV with normal audiological evaluations at birth is easily lost to follow-up. Close collaboration between neonatologists, pediatricians, and audiological services is fundamental to ensure timely diagnosis and treatment of cCMV-related hearing loss.

Acquired bilateral facial palsy: a systematic review on aetiologies and management.

OBJECTIVE: To systematically review the published cases of bilateral facial palsy (BFP) to gather evidence on the clinical assessment and management of this pathology. METHODS: Following PRISMA statement recommendations, 338 abstracts were screened independently by two authors. Inclusion criteria were research articles of human patients affected by BFP, either central or peripheral; English, Italian, French or Spanish language; availability of the abstract, while exclusion criteria were topics unrelated to FP, and mention of unilateral or congenital FP. Only full-text articles reporting the diagnostic work-up, the management, and the prognosis of the BFP considered for further specific data analysis. RESULTS: A total of 143 articles were included, resulting a total of 326 patients with a mean age of 36 years. The most common type of the paralysis was peripheral (91.7%), and the autoimmune disease was the most frequent aetiology (31.3%). The mean time of onset after first symptoms was 12 days and most patients presented with a grade higher than III. Associated symptoms in idiopathic BFP were mostly non-specific. The most frequently positive laboratory exams were cerebrospinal fluid analysis, autoimmune screening and peripheral blood smear, and the most performed imaging was MRI. Most patients (74%) underwent exclusive medical treatment, while a minority were selected for a surgical or combined approach. Finally, in more than half of cases a complete bilateral recovery (60.3%) was achieved. CONCLUSIONS: BFP is a disabling condition. If a correct diagnosis is formulated, possibilities to recover are elevated and directly correlated to the administration of an adequate treatment.

Foreign Body in the Cervical Oesophagus: A Case Report.

BACKGROUND: Foreign bodies in the upper aerodigestive tract represent an uncommon cause of visits to emergency departments. In the majority of cases, foreign bodies do not go beyond the pharynx. They cause dyspnoea or pneumonia if they reach the tracheobronchial tree. If ingested, they will pass spontaneously through the gastrointestinal canal in the majority of cases. Nevertheless, especially in the case of sharp-pointed or large objects, the foreign bodies can stop in the oesophagus. In case of dysphagia, stinging sensation and/or odynophagia occurring after eating a meal, a foreign body in the upper aerodigestive tract should be suspected. If not clinically visible, imaging is required. CASE PRESENTATION: A 72-year-old woman presented to the Emergency Department with pharyngodynia, odynophagia, stinging, dysphagia, and sialorrhea for 12 hours. Her symptoms started after eating a meal involving meat. The patient underwent a standard two-projection radiogram of the neck. The antero-posterior projection radiogram was unremarkable. The lateral projection radiogram showed 16 millimetres in maximum length radiopaque foreign body within the cervical oesophagus. The patient underwent transoral flexible oesophagoscopy under general anaesthesia, which resulted in successful removal of the foreign body (bony fragment). Her symptoms improved rapidly after the procedure, and the patient was discharged after 48 hours in good health. CONCLUSION: A foreign body in the cervical oesophagus may lead to visceral perforation. Once suspected, every effort should be made to identify and remove the foreign body to avoid potentially catastrophic consequences. In some cases, imaging could be necessary to detect the foreign body.

Congenital Nasal Pyriform Aperture Stenosis: Successful Management of Restenosis After Primary Surgery by Stent Placement.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare anomaly causing respiratory distress in newborns. While the primary surgical technique is well established, the timing of the removal of the stents and the management of restenosis remain a matter of debate. We report a case of a female newborn affected by CNPAS with the recurrence of respiratory distress after primary surgery due to the early removal of nasal stents, causing an overgrowth of granulation tissue. This report notes that restenosis was successfully managed by repeating the procedure over a 14-day period, with soft polyvinyl chloride uncuffed tracheal tubes acting as nasal stents.

Spontaneous Upbeat Nystagmus and Selective Anterior Semicircular Canal Hypofunction on Video Head Impulse Test: A New Variant of Canalith Jam?

We describe a rare case of spontaneous upbeat nystagmus (UBN) attributable to a canalith jam involving the anterior semicircular canal (ASC) in a patient in whom comprehensive vestibular assessment was useful to identify the underlying pathomechanism. A 56-year-old woman with unsteadiness following repositioning procedures for left-sided benign paroxysmal positional vertigo (BPPV) presented with spontaneous UBN that showed slight right torsional components. A vestibular test battery detected isolated left ASC hypofunction on a video-head impulse test (Video-HIT). We postulated a persistent utriculopetal deflection of the left ASC cupula, which was attributable to entrapment of debris in a narrow canal tract, with consequent sustained inhibition of the ampullary afferents. Although spontaneous UBN receded after impulsive physical therapy, unsteadiness deteriorated into positional vertigo secondary to canalolithiasis involving the ipsilateral posterior canal. In our view, physical therapy possibly fragmented the canalith jam and released free-floating otoconia that eventually settled into the ipsilateral posterior canal. Video HIT revealed normalization of ASC hypofunction, and leftsided posterior canal canalolithiasis was successfully treated using appropriate repositioning procedures. We propose that a canalith jam involving the ASC should be considered in the differential diagnosis of spontaneous UBN, particularly in patients with a history of BPPV and isolated ASC hypofunction detected on video HIT.

Hemithyroidectomy and ipsilateral central neck dissection for T1 low-risk papillary thyroid cancer: single-institution retrospective observational study.

Objective: The aim of this study was to report the rationale and selection criteria for hemithyroidectomy and ipsilateral central neck dissection in patients with selected papillary thyroid cancer and to report the surgical and oncological outcomes. Design: Single-institution retrospective observational study. Methods: The clinical records of patients with a histopathological diagnosis of low-risk pT1 papillary thyroid cancer who underwent hemithyroidectomy with or without ipsilateral central neck dissection between March 2000 and April 2018 at a tertiary referral center were retrospectively reviewed. Demographic, clinical, and histopathological data were collected. Results: During the study period, 176 patients underwent hemithyroidectomy for PTC. Thirteen patients (13/176, 7.39%) were lost to follow-up and 74 patients (74/163 45.40%) underwent completion thyroidectomy within 1 month because they were classified intermediate ATA initial risk based on definitive pathology. The final study group was composed of 89 patients, who had a median follow-up of 5.3 years. The mean follow-up was 6.3 years (range: 36-207 months). Eighty-four patients (94.38%) did not experience recurrence in the follow-up period. A total of 5/89 patients (5.62%) underwent delayed completion thyroidectomy with or without neck dissection for recurrent malignancy in the residual lobe (3/5) or regional lymph nodes (2/5). The median time from surgery to recurrence was 24.8 months (range: 6-60). The follicular variant was an independent risk factor for recurrence. Conclusions: Hemithyroidectomy with or without prophylactic ipsilateral central neck dissection is a valuable treatment option in selected low-risk papillary thyroid cancers and ensures a low risk of recurrence. Prophylactic ipsilateral central compartment dissection could have a role in improving cancer staging, and accurate ultrasonographic follow-up is essential to identify local recurrence.

Management of Jugular Bulb Injury During Transcanal Endoscopic Tympanoplasty.

Variable internal jugular vein anatomy is not rare. A high jugular bulb (JB) is reported in 6 to 34% of cases and, it can be jeopardized during middle ear surgery, especially if dehiscent. Its injury represents a threatening complication of ear surgery. In recent years there has been an increasing trend in the use of endoscopic ear surgery for a wide range of otologic procedures, but being a one-hand technique, the management of bleeding still represents a challenge. The aim of this video, http://links.lww.com/MAO/B280 is to report the endoscopic surgical management of internal jugular vein hemorrhage during endoscopic type I tympanoplasty.

Use of Foley catheter in control of internal carotid hemorrhage during endoscopic endonasal surgery.

Internal carotid artery (ICA) injuries during endoscopic endonasal surgery (EES) are rare life-threatening events. We describe a technique to manage ICA injuries based on the use of Foley catheters.A 26-year-old female underwent endoscopic transnasal trans-sphenoidal removal of pituitary adenoma. Cerebrospinal fluid leak occurred 4 days postoperatively. During repair procedure, accidental injury of ICA occurred. Emergency nasal packing through positioning of four Foley urologic catheters was successfully performed to stop bleeding. The patient did not report neurologic deficits.In author's opinion, Foley catheters are suitable to obtain immediate bleeding control since they are rapidly available and easily usable.

Comparison of percutaneous dilatational tracheotomy versus open surgical technique in severe COVID-19: Complication rates, relative risks and benefits.

OBJECTIVE: Patients with acute respiratory failure due to COVID-19 have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Usually, the choice of technique (percutaneous dilatational tracheotomy [PDT] versus open surgical tracheotomy [OST]) depends on the preference of surgeons and patient-related factors. In case of COVID-19, airborne spread of viral particles and limited time of apnea must be considered in the choice of the safest technique. The aim of this study is to compare the complication rates and offer an assessment of relative risks and benefits of PDT versus OST in patients with severe COVID-19. METHODS: We performed a retrospective study considering 47 consecutive patients affected by severe acute respiratory distress syndrome due to SARS-CoV-2 infection, needing invasive mechanical ventilation and subsequent tracheostomy. This study was performed at the Intensive Care Unit of our tertiary referral center. Complication rates were analyzed. RESULTS: Seventeen patients underwent PDT and 30 patients were submitted to OST. Twenty-six patients (55.3%) had post-operative complications (local infection, hemorrhage, subcutaneous emphysema) with no significant difference between PDT and OST. CONCLUSION: PDT and OST are characterized by similar postoperative complication rates in severe COVID-19 patients. These findings suggest that OST might be preferred if expert ENT surgeons are available, as PDT could result in longer apnea and exposure to generated aerosol. However, authors recommend considering either OST or PDT at the discretion of the medical staff involved, according to the personal experience of the operators performing the procedure.

Unexpected hearing improvement after treatment with valganciclovir in a child with congenital cytomegalovirus infection.

A 32-week preterm-born male with symptomatic congenital cytomegalovirus infection was treated with valganciclovir. He was also affected by congenital severe bilateral hearing loss and, unexpectedly, a normalization of the hearing threshold was reached at one year of age. The improvement of hearing level in relationship with both the late development of the auditory system and the administration of antiviral therapy is discussed. This case also highlights the importance of early diagnosis of congenital cytomegalovirus associated with close follow-up.
