Surgical site complications of isolated salvage neck dissection post-radiotherapy and post-chemoradiotherapy - A cohort analysis (1997-2017).

INTRODUCTION: This study aims to quantify surgical site complications (SSC) after isolated salvage neck dissection (ND) compared with primary ND. PATIENTS AND METHODS: Between 1997 and 2017 in the Netherlands Cancer Institute - Antoni van Leeuwenhoek, a total of 323 isolated NDs were performed in 308 patients: primary ND (n = 144), post-radiotherapy (RT) ND (n = 53) and post-chemoradiotherapy (CRT) ND (n = 126). Patient, tumor and therapy characteristics were recorded. SSCs were scored according to the Clavien-Dindo Classification (CDC). RESULTS: 101 NDs (31%) were complicated by at least one SSC. In total, 189 different SSCs occurred. Translated to CDC, 45 complications were grade 2, 25 grade 3a and 31 grade 3b. No significant difference in occurrence of SSC (CDC >1) was found between all groups. However, post-CRT, selective (SND) and modified radical ND and radical ND (MRND/RND) (p = 0.005), resection of sternocleidomastoid muscle (SCM) (p = 0.039) and duration of super selective ND surgery (p = 0.048) were significantly associated with more SSC. SCM muscle removal was associated with more surgical site infection (p = 0.045) and necrosis (p = 0.036). From week 10 post-RT/CRT, no difference in complication frequency with primary ND was seen. CONCLUSION: Post-CRT SND, MRND/RND and SCM muscle resection were associated with an increased incidence of SSCs. If oncologically possible, limit the extent of ND and when an MRND is inevitable, preserve the SCM muscle for optimal prevention of SSC. Concerning SSC, optimal timing of salvage ND is minimal 10 weeks after RT/CRT.

Silver ring splints improve dexterity in patients with rheumatoid arthritis.

OBJECTIVE: To study the effect of Silver Ring Splints (SRSs) on hand function in patients with rheumatoid arthritis (RA). METHODS: RA patients with stable disease and finger deformities eligible for splinting received 1 or more SRSs. Primary outcome was dexterity, which was measured with the Sequential Occupational Dexterity Assessment (SODA). Secondary outcome measures were self-reported hand function (Dutch Arthritis Impact Measurement Scales 2), hand pain, grip and pinch strength, Disease Activity Score in 28 joints (DAS28), and patient satisfaction. RESULTS: Seventeen patients (median age 65 years; median disease duration 21 years) received a total of 72 SRSs. After 1 year, 48 SRSs were regularly used. Two patients dropped out because of adverse events related to SRSs. In the remaining 15 patients, SODA dexterity scores increased significantly (median 71 at baseline, 81 at 3 months, and 85 at 12 months), Wilcoxon signed ranks test P=0.005 and P=0.026. DAS28 scores did not change at 3 months and improved slightly after 12 months (-0.5; P=0.019). Grip strength, self-reported hand function, and hand pain showed no significant changes. Eleven patients stated they would continue using their splints. CONCLUSION: SRSs can improve dexterity in selected patients with rheumatoid hand deformities. For a satisfactory result, careful patient preassessment and optimal adjustment of SRSs are essential.
