Abstract BACKGROUND: The dislocation rate of oral versus nasal airway exchange catheters (AEC) in the postoperative care unit (PACU) are unknown. Our aim was to establish dislocation rates and to assess the usefulness of waveform capnography to detect dislocation. METHODS: In this non-randomized, prospective observational trial at the University Hospital Bern, Switzerland, we included 200 patients admitted to PACU after extubation via AEC, having provided written informed consent. The study was approved by the local ethical committee. AEC position was assessed by nasal fiberoptic endoscopy at beginning of PACU stay and before removal of the AEC. Capnography was continuously recorded via the AEC. Additional measurements included retching and coughing of the patient, and re-intubation, if necessary. RESULTS: Data from 182 patients could be evaluated regarding dislocation. Overall dislocation rate was not different between oral and nasal catheters (7.2% vs. 2.7%, p=0.16). Retching was more often noted in oral catheters (26% vs. 8%, p<0.01). Waveform capnography was unreliable in predicting dislocation (negative predictive value 17%). Re-intubation was successful in all five of the nine re-intubations where an AEC was still in situ. In four patients, the AEC was already removed when re-intubation became necessary, and re-intubation failed once, with a front of neck access as a rescue maneuver. CONCLUSIONS: We found no difference in dislocation rate between nasal and oral position of an airway exchange catheter. However, nasal catheters seemed to be tolerated better. In the future, catheters like the staged extubation catheter may further increase tolerance. TRIAL REGISTRATION: The study was registered in a clinical study registry (ISRCTN 96726807) on 10/06/2010.

Introduction: To report the spectrum and frequency of conjunctiva tumours in an ocular oncology unit analysing the clinical profile of benign, precancerous and malignant conjunctival lesions. Methods: A retrospective case series of 462 consecutive patients diagnosed at the Ocular Oncology Unit of the University Hospital of Valladolid from 1992 to 2017. Results: Among 462 consecutive patients, the tumour was classified as melanocytic in 252 (54.5%) and non-melanocytic in 210 (45.5). Two hundred forty-eight males (mean age 51.63 (SD = 23.20)) and 214 females (mean age 48.27 (SD = 21.77)) were included. Mean patient age at diagnosis was 50.07 years (range = 1-92 years). The majority of tumours were benign (n = 307 (66.5%)) followed by precancerous (n = 103 (22.3%)) and finally by malignant ones (n = 52 (11.3%)). Benign lesions were predominantly found in younger individuals rather than premalignant (p < 0.05) and malignant ones (p < 0.05). Most of the melanocytic lesions were benign (88.5%), most epithelial ones were precancerous (61.4%) and most lymphoid lesions were malignant (56.3%). Tumours involving one or four quadrants of the ocular surface usually were benign, unlike tumours involving three quadrants that were malignant (16 (48.5%) p < 0.05). The majority of benign lesions were detected on females (n = 163 (53.1%)) by routine examination (n = 178 (86.4%)). However, main complaint in malignant tumours was the growth of the lesion (n = 39 (76.5%)). Conclusion: Most of the conjunctival tumours were melanocytic, mostly benign, closely followed by those of epithelial origin, with a predominance of precancerous lesions. Melanocytic, epithelial and lymphoid tumours accounted for over 90% of cases. A trend was identified with benign lesions being found in younger female patients on routine examination.

Flow Diverting Stent

Background and Purpose: Flow diverting stents are designed to divert blood flow from the aneurysm sac, allowing for eventual occlusion following endovascular therapy. This case series reports clinical experience using the Silk Vista Baby (SVB, Balt Extrusion, Montmorency, France), a flow diverter (FD) designed to treat intracranial aneurysms in small, distal vessels.Methods: All patients who underwent treatment with SVB at the University Hospital “Santa Maria della Misericordia” of Udine between July 2018 and September 2020 were retrospectively identified. Baseline patient and aneurysm characteristics, intraprocedural technical outcomes, periprocedural complications, modified Rankin Scale (mRS) at discharge, magnetic resonance imaging (MRI) results at 3-month follow-up, and angiographic results at 6-month follow-up were collected.Results: A total of 18 patients (55.6% [10/18] male; mean age 62.6 years, range: 42–77 years) were retrospectively identified, receiving treatment for 22 aneurysms. Most patients were symptomatic (14/18, 77.8%) and approximately half had subarachnoid hemorrhage (10/18, 55.6%). Sufficient aneurysm coverage was achieved in 88.9% (16/18) of patients with a single device. Mortality did not occur (0/18, 0%); adverse device-related events included side branch occlusion (1/18, 5.6%) and in-stent thrombosis (1/18, 5.6%). At discharge, 77.8% (14/18) had an mRS of 0. In most cases, patients showed complete occlusion (10/15, 66.7%) or a small aneurysmal remnant (3/15, 20.0%) upon MRI; upon angiography, most showed complete occlusion (10/13, 76.9%) or only a small aneurysmal remnant (2/13, 15.4%).Conclusion: This case series showed that the SVB FD is safe and feasible to use in patients with aneurysms in small, distal vessels. Additional randomized, prospective studies with larger cohorts are needed for the SVB.

Introduction: Fungal rhinosinusitis (FRS) remains a rare disease. The noninvasive forms are hard to diagnose. The management protocols remain controversial. We aim to describe the clinical, radiological and pathological features of noninvasive FRS and present our management protocol and follow-up results. Patients and methods: This descriptive study was conducted in the ear-nose-throat department of the university hospital, Taher Sfar in Mahdia, Tunisia. All patients who responded to the definition of noninvasive FRS (fungal balls and allergic fungal sinusitis) were included. The study was conducted over a three year period (May 2017 – April 2021). Results: Eleven patients were included in this study: four cases of fungal balls and seven cases of allergic fungal sinusitis. Patients presented with symptoms of chronic recurrent rhinosinusitis with no response to conventional treatments. Computed tomodensitometry scan showed opacification of the paranasal sinuses in all patients. Other signs were heterogeneous opacities, local calcifications and thinning of the bony walls of the sinuses. Histopathological findings were inflammatory polyps in all cases of allergic FRS with the presence of fungal hyphae in 42.8% of the cases. All patients underwent surgery after a median delay of 12 [6–24] months of the symptom’s onset. The used procedures were endoscopic middle meatal antrostomy for all patients, ethmoidectomy (81.8%) and sphenoidotomy (36.4%). None received systemic antifungals or corticosteroids with a favorable outcome in all cases. Conclusion: Symptoms of noninvasive FRS are nonspecific. The scan images contribute to the diagnosis, but the perioperative findings and the histopathological results remain crucial.  The management is mainly surgical.

Background: Due to the importance of function and cosmetics, periocular skin malignancies represent a therapeutic challenge. Objective: To evaluate the safety and efficacy of radiotherapy (RT) treating periocular skin tumors. Methods: Data of patients with periocular tumors treated with grenz or soft X-rays at the University Hospital Zurich, Switzerland, between 2009 and 2014 were reviewed. Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) with associated in situ lesions, cutaneous melanoma, lentigo maligna (LM), cutaneous lymphoma and Kaposi’s sarcoma were included in the analysis. Results: We found 159 periocular lesions in 145 patients. Overall recurrence was highest for actinic keratosis and Bowen’s disease (27%), melanoma (17%) and LM (15%), whereas SCC and BCC showed recurrence in 11 and 10%, respectively. 45% of all recurrences occurred within 12 months after treatment, with a median time to recurrence of 13 months (range 3–73). Conclusion: RT, which provides a good therapeutic response with minimal adverse events, is a therapy option for periocular cutaneous malignancies.
