Transoral septotomy with septum traction is an effective treatment for recurrent Zenker diverticulum.

Symptoms of Zenker diverticulum can recur whatever the type of primary treatment administered. A modified transoral stapler-assisted septotomy (TS) was introduced in clinical practice a few years ago to improve the results of this mini-invasive technique. The aim of this prospective, controlled study was to assess the outcome of TS in patients with recurrent Zenker diverticulum (RZD), as compared with patients with treatment-naïve Zenker diverticulum (NZD). Patients diagnosed with NZD or RZD, and treated with TS between 2015 and 2021 were compared. Symptoms were recorded and scored using a detailed questionnaire. Barium swallow and endoscopy were performed before and after the TS procedure. In sum, 89 patients were enrolled during the study period: 68 had NZD and 21 had RZD. The patients' demographic and clinical data were similar in the two groups. Three mucosal lesions were detected intra-operatively, and one came to light at post-operative radiological assessment in the NZD group. No mucosal lesions were detected in the RZD group. The median follow-up was 36 months (interquartile range 23-60). The treatment was successful in 97% NZD patients and 95% of RZD patients (P = 0.56). This is the first comparative study based on prospectively collected data to assess the outcome of TS in patients with RZD. Traction on the septum during the procedure proved effective in the treatment of RZD, achieving a success rate that was excellent, and comparable with the outcome in treating NZD.

Clinical implications of alpha, beta, and gamma HPV infection in juvenile onset recurrent respiratory papillomatosis.

PURPOSE: The aim of our study was to evaluate the prevalence of different HPV genera-alpha, beta and gamma-in Juvenile onset Recurrent Respiratory Papillomatosis (JoRRP) and examine the association of type and genus-specific viral features with the clinical outcome of disease. METHODS: This retrospective observational study included consecutive patients with JoRRP who were treated in a referral centre between October 2000 and October 2020. All patients underwent cold excision and laser vaporisation of papillomatous lesions. Samples were analysed for the presence of 120 viral genotypes (22 alpha-HPV, 46 beta-HPV, 52 gamma-HPV) using a highly sensitive multiplex genotyping assay. RESULTS: Twenty patients with JoRRP, aged 0.3-11 years, were included, with a median follow-up of 13.5 years. All samples were HPV DNA positive: 20 (100%) for alpha-HPV DNA; 7 (35%) for beta-HPV DNA; 0 for gamma-HPV DNA. Three groups were defined according to the number of infections: seven cases (35%) with HPV mono-infection; ten cases (50%) with HPV double-infection; three cases (15%) with ≥ 3 HPV infections. At diagnosis, patients with ≥ 3 HPV infections reported higher median Derkay's score than those with mono-infection (21 vs 14, P = 0.018). Number of HPV infections was also associated with clinical outcomes, with an average of 0.5 surgical procedures/year in patients with mono-infection, 1.2 for double-infection, 2.6 for ≥ 3 infections (P = 0.006). CONCLUSION: Despite the small sample size, these preliminary data support an association between the number of different alpha and beta HPV co-infections and the clinical severity of the disease.

Clinical features and outcome of Cogan syndrome.

OBJECTIVE: To review the clinical features of Cogan syndrome, a rare vasculitis characterized by systemic, ocular, and audiovestibular symptoms. STUDY DESIGN: Clinical records of patients with Cogan syndrome followed at 2 pediatric rheumatology institutions and those from a database search were reviewed. Data included clinical features at onset and during the disease course, treatments, and outcomes. RESULTS: Twenty-three children with Cogan syndrome (15 males; mean age, 11.4 years [range, 4-18 years]) were included in the analysis. Eleven patients (47.8%) exhibited systemic features at disease onset, including fever, arthralgias-arthritis or myalgias, headache, and weight loss. Twenty-one patients (91.3%) had ocular symptoms, due mainly to interstitial keratitis, uveitis, or conjunctivitis/episcleritis. Vestibular symptoms (39.1%) included vertigo, vomiting, and dizziness. Auditory involvement (65.2%) consisted of sensorineural hearing loss, tinnitus, and deafness. Four patients had cardiac valve involvement, and 3 had skin manifestations. After a median 2 years of follow-up, 30.4% of the patients were in clinical remission, but all others had irreversible complications (deafness, 21.7%; sensorineural hearing loss, 13.0%; vestibular dysfunction, 4.3%; ocular complications, 13.0%; cardiac valve damage, 17.4%). CONCLUSION: Audiovestibular and ocular involvement have a major impact on prognosis in children with Cogan syndrome.

Rational diagnostic and therapeutic management of deep neck infections: analysis of 233 consecutive cases.

OBJECTIVES: Although deep neck infections are less common nowadays because of the widespread use of antibiotics, they continue to carry significant morbidity and mortality rates. METHODS: Between 2000 and 2008, deep neck infections were treated in 233 patients at the University of Padova. Cases of peritonsillar abscess, superficial infections, infections due to external neck injuries, and infections in head and neck tumors were excluded. Clinical, radiologic, laboratory, and microbiological assessments were analyzed. RESULTS: The site of origin was identified in 189 of the 233 cases (81.1%), and the most common cause of deep neck infection was dental infection (39.5%). Intravenous antibiotic therapy was given to 78 patients, and 155 required both medical and surgical procedures. The bacteria most often isolated were gram-positive anaerobic cocci. None of our patients died of the deep neck infection or its complications. CONCLUSIONS: It is worth emphasizing that airway support is the priority in patients with deep neck infections. Empirical antibiotic treatments must cover gram-positive and gram-negative aerobic and anaerobic pathogens. Surgical exploration and drainage may be mandatory in selected cases at presentation or in cases that fail to respond to parenteral antibiotics within the first 24 to 48 hours. It is important to perform cultures during operation to establish the pathogen(s) involved and to obtain an antibiogram to tailor the antibiotic treatment.

Maspin nuclear localization is related to reduced density of tumour-associated micro-vessels in laryngeal carcinoma.

BACKGROUND: MASPIN, a tumour suppressing serpin, is a potent inhibitor of angiogenesis. CD105 is a proliferation-associated protein acting in endothelial cells of angiogenic tissues. For the first time the relation between nuclear MASPIN expression and CD105-assessed micro-vessel density (MVD) in laryngeal carcinoma was investigated. PATIENTS AND METHODS: The sub-cellular distribution of MASPIN and nuclear MASPIN expression were immunohistochemically determined in 35 cases of laryngeal carcinoma. The percentage of the fields occupied by CDl05-assessed micro-vessels was also calculated. RESULTS: MVD was significantly lower in laryngeal carcinomas with MASPIN nuclear staining than in carcinomas with cytoplasmic staining (p=0.02). The mean nuclear MASPIN expression was higher in patients without carcinoma recurrence than in those with recurrence (p=0.06). The mean MVD was significantly higher in patients with recurrence of carcinoma (p=0.024). CONCLUSION: The crucial role of MASPIN nuclear localization in reducing the MVD has been demonstrated. Nuclear MASPIN re-expression should be investigated as a potential therapeutic option in the treatment of laryngeal carcinoma.

Intracranial venous sinus thrombosis as a complication of otitis media in children: Critical review of diagnosis and management.

OBJECTIVES: Otogenic lateral sinus thrombosis (LST) is a rare intracranial complication of acute otitis media (AOM), which can lead to severe neurological sequelae and death. The aim of this study was to analyze the clinical presentation, management and outcome of LST in children, investigating a possible correlation between clinical aspects, radiological findings and anatomical variations. METHODS: At a tertiary Italian hospital, a retrospective review was conducted on the medical records of eight patients diagnosed with otogenic LST over a 3-year period. Four children were males and mean age was 4.7 years. RESULTS: All patients had a history of otitis media at diagnosis and 4/8 presented also with more than one neurological sign or symptom. Mastoiditis signs were detected in 5/8 patients. Thrombosis was diagnosed by computed tomography, enhanced magnetic resonance and magnetic resonance venography. Treatment was medical, alone or combined with surgery. Medical treatment consisted in anticoagulants eventually combined with anti-edema medication on clinical basis. Mastoidectomy and/or myringotomy±trans-tympanic drainage placement were performed in 7/8 patients. Complete vessel recanalization was obtained in 6/8 children after a median follow-up time of 4.8 months. No complications, neither clinical sequelae occurred. In our series, neurological signs and symptoms were significantly associated with the presence of hypoplasia of the contralateral venous sinus (p=0.029). CONCLUSION: LST is a severe condition occurring even in absence of otological signs, and despite adequate antibiotic therapy for AOM, which should be ruled out and promptly treated. A dominant neurological presentation is associated in our series with anatomical variations of cerebral sinus venous drainage patterns. This should be carefully evaluated and considered in diagnosis, treatment planning and prognosis.

The complimentary role of diagnostic and therapeutic endoscopy in foreign body aspiration in children.

OBJECTIVE: To review the importance and benefits of flexible bronchoscopy and rigid bronchoscopy in airway foreign body inhalation in children. Prompt diagnosis will lead to safer outcomes when both types of endoscopy are employed within the operating room setting. METHODS: Retrospective review of all cases of foreign body inhalation seen and treated in our Department between July 1986 and December 2010. RESULTS: Three-hundred and ten children were admitted to our Department from Pediatric Emergency Room for a suspected foreign body inhalation. All patients with suspected FB inhalation underwent bronchoscopy. Of 310 evaluations of tracheobronchial tree performed at our Department, 104 were negative, while an airway FB were observed and removed in 206 cases. CONCLUSIONS: Rigid bronchoscopy under general anesthesia is an extremely accurate surgical technique to identify, localize and remove airway foreign body. In our experience, flexible bronchoscopy under total intravenous sedation and topical anesthesia is very useful in doubtful cases to absolutely exclude the presence of foreign body in upper airway tracheobronchial tree.

Otolaryngological manifestations of rheumatic diseases in children.

Rheumatic diseases represent a group of autoimmune conditions which primarily affect the musculo-skeletal system but can also involve other internal organs such as the auditory and the respiratory systems. Among the rheumatic diseases of children those which present an otolaryngological involvement at disease onset or during their course are essentially juvenile idiopathic arthritis (JIA), Cogan syndrome (CS), relapsing polycondritis (RPC) and Wegener granulomatosis (WG). In this section, we will review the main characteristics of these conditions with the attempt to propose a few elements for an easy differential diagnosis which might help for an early diagnosis and a more appropriate treatment.
