Immunotherapy for the treatment of perineural spread in cutaneous head and neck squamous cell carcinoma: Time to rethink treatment paradigms

xlomafota13 shared this article with you from Inoreader

Abstract

Background

Immune checkpoint inhibitors have shown promising antitumour activity. Application in head and neck cutaneous squamous cell carcinoma (cSCC) large nerve perineural spread (PNS) is limited.

Methods

Retrospective review of 13 patients with PNS receiving anti-PD-1 therapy from September 2017 to May 2021 is presented. Primary endpoints were objective response (complete or partial response) and median time to progression, determined by Head and Neck Multi-Disciplinary Team (MDT) and independent radiology review of magnetic resonance imaging (MRI) and/or computed tomography/positron emission tomography (CT/PET).

Results

Objective response was observed in 9/13 patients (69%), with complete response in 6 (46%) and partial response in 3 patients (23%). Median time to response was 2.1 months (IQR 1.8–2.7 months). There were 3 (23%) patients with progressive disease, with median time to progression of 3.5 months. There were no grade 3–4 treatment related adverse events.

Conclusions

This case series supports developing evidence for anti-PD-1 checkpoint inhibitor therapy for perineural spread, supporting future prospective clinical trials in this patient population.

Aggressive paediatric camptodactyly: The evolution of a proposed treatment algorithm

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2022 Jan 22:S1748-6815(22)00034-1. doi: 10.1016/j.bjps.2022.01.020. Online ahead of print.

ABSTRACT

INTRODUCTION: It is a long-established teaching to avoid operating on camptodactyly unless there is a failure of non-operative treatment, such as serial splinting and hand therapy, and there is an established proximal interphalangeal joint (PIPJ) contracture of 60°; a recent systematic review reflects this continuing approach, with some papers advocating intervention with a lesser degree of contracture.

AIM: To evaluate whether early flexor digitorum superficialis (FDS) release, followed by gentle passive manipulation (GPM), will correct severe 'congenital' camptodactyly, if undertaken at an earlier age than usual, thus avoiding the more aggressive surgical approach required in the established adolescent cases.

METHOD: The surgical technique and treatment algorithm are described. A multi-centre case series is presented; data analysis included patient demographics, syndromic association, side/digit affected, ages at onset, progression, referral and at surgery, operation details, pre- and post-operative contracture and range of motion.

RESULTS: There were 12 patients (3 males, 9 females) who underwent 15 operations for 24 involved digits. Patients had surgery by 3 months (median) post-referral, and there was a significant improvement in median (range) PIPJ contracture (90°(30°-90°) vs. 0°(0°-45°); p<0.001) and range of motion (0°(0°-60°) vs. 90°(50°-95°); p<0.001), at a median post-operative follow-up of 2.5 years. According to the Siegert grade, 87.5% of digits had excellent/good post-operative outcomes and 12.5% had fair outcomes.

CONCLUSION: This paper specifically addresses the problem of aggressive and progressive camptodactyly in the young child. By this, we mean patients who have failed non-operative treatment and have PIPJ contractures ≥60°, and those whose contractures have increased by 30° within 1 year. All cases responded to early FDS release and GPM, hence correcting the PIPJ contracture. However, cases with multiple digital involvement, whether syndromic or not, and failed previous surgery or the older child, required additional procedures to restore a dynamic dorsal apparatus and active extension.

Prevalence of abnormal vestibular responses in children with sensorineural hearing loss

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Feb 14. doi: 10.1007/s00405-021-07241-2. Online ahead of print.

ABSTRACT

PURPOSE: Dysfunction of the vestibular organs has a great deal of influence on children's balance. Children with sensorineural hearing loss (SNHL) may often have accompanying abnormal vestibular responses. Video head impulse test (vHIT) combined with a test battery of cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) make it possible to determine the prevalence of abnormal vestibular response in any of the five paired vestibular organs amongst children with SNHL.

METHOD: Prospective cross-sectional study including children aged 3-17 years with uni- or bilateral SNHL (bone-conduction (BC) pure tone average (PTA4) above 20 dB). Assessments included vHIT, cVEMP, and oVEMP. Descriptive data were analyzed. T-tests were performed to detect any correlation between the degree of SNHL and abnormal ve stibular responses.

RESULTS: 42 children (27 males), a total of 63 ears with SNHL, mean BC PTA4 SNHL of 42.3 dB (32.0; 58.4 IR) were included. 28.6% had at least one ear with abnormal vestibular response. 97.6% (41/42) completed one and 75.0% (27/36) completed all vestibular examinations. Ears with two pathological examinations had significantly more severe SNHL than ears with one pathological or normal vestibular examinations (p = 0.008, p = 0.005).

CONCLUSION: All test methods used with this study were easy, fast, and comfortable for children (as young as 3 years of age) to undergo. Even a moderate SNHL might be associated with abnormal vestibular response. Structural damage to the organs is the most likely cause of vestibular deficit. Consensus on criteria defining pathological examinations with both vHIT and VEMPs are required for more accurate comparison with previous studies.

Bow Hunter's syndrome with a dominant aberrantly coursing right vertebral artery (VA), presenting with persistent dizziness and syncope

xlomafota13 shared this article with you from Inoreader

Message:

Bow hunter syndrome (BHS) is an uncommon cause of vertebrobasilar insufficiency that results from occlusion or injury to the vertebral artery (VA) during neck rotation. The cause is often a bony abnormality that may compress the VA compromising distal flow or lead to vessel wall injury resulting in thromboembolism.

ABSTRACT

OBJECTIVES AND METHODS: We report a unique case of Bow Hunter's syndrome with a dominant aberrantly coursing right vertebral artery (VA), presenting with persistent dizziness and syncope despite previous decompressive surgery at vertebral levels C5-C6.

RESULTS: Re-evaluation with computed tomography-scan during provocation of dizziness by neck rotation revealed compression of the right VA at level C6 from against the ipsilateral posterior border and superior cornu of the thyroid cartilage. Laryngoplasty resulted in complete resolution of symptoms.

CONCLUSION: This extremely rare cause of Bow's Hunter's syndrome should be considered, especially in refractory cases after neurosurgical decompression, and surgical management is straightforward and successful.

Serratus Anterior-Rib Composite Flap as a Novel Approach for Tracheal Reconstruction

xlomafota13 shared this article with you from Inoreader

pubmed-meta-image.png

Ann Otol Rhinol Laryngol. 2022 Feb 13:34894211067608. doi: 10.1177/00034894211067608. Online ahead of print.

ABSTRACT

OBJECTIVE: To report a novel case of tracheal reconstruction using a serratus anterior-rib composite flap.

METHODS: Case report and literature review.

RESULTS: A 46-year-old male with a 4 cm anterior tracheal wall defect underwent reconstruction with a serratus anterior-rib composite flap. The patient experienced excellent results regarding phonati on, swallowing, and cosmesis.

CONCLUSION: The serratus anterior-rib composite flap appears to be a suitable candidate for tracheal reconstruction and merits further analysis in this context. The flap's intrinsic incorporation of a perfused rib segment allows for reliable reconstruction of the neotrachea and maintenance of proximal dynamic airway support.
