OBJECTIVEThe long-term effects of surgical fusion on the growing subaxial cervical spine are largely unknown. Recent cross-sectional studies have demonstrated that there is continued growth of the cervical spine through the teenage years. The purpose of this multicenter study was to determine the effects of rigid instrumentation and fusion on the growing subaxial cervical spine by investigating vertical growth, cervical alignment, cervical curvature, and adjacent-segment instability over time.METHODSA total of 15 centers participated in this multi-institutional retrospective study. Cases involving children less than 16 years of age who underwent rigid instrumentation and fusion of the subaxial cervical spine (C-2 and T-1 inclusive) with at least 1 year of clinical and radiographic follow-up were investigated. Charts were reviewed for clinical data. Postoperative and most recent radiographs, CT, and MR images were used to measure vertical growth and assess alignment and stability.RESULTSEighty-one patients were included in the study, with a mean follow-up of 33 months. Ninety-five percent of patients had complete clinical resolution or significant improvement in symptoms. Postoperative cervical kyphosis was seen in only 4 patients (5%), and none developed a swan-neck deformity, unintended adjacent-level fusion, or instability. Of patients with at least 2 years of follow-up, 62% demonstrated growth across the fusion construct. On average, vertical growth was 79% (4-level constructs), 83% (3-level constructs), or 100% (2-level constructs) of expected growth. When comparing the group with continued vertical growth to the one without growth, there were no statistically significant differences in terms of age, sex, underlying etiology, surgical approach, or number of levels fused.CONCLUSIONSContinued vertical growth of the subaxial spine occurs in nearly two-thirds of children after rigid instrumentation and fusion of the subaxial spine. Failure of continued vertical growth is not associated with the patient’s age, sex, underlying etiology, number of levels fused, or surgical approach. Further studies are needed to understand this dichotomy and determine the long-term biomechanical effects of surgery on the growing pediatric cervical spine.

OBJECT The long-term consequences of atlantoaxial (AA) and occipitocervical (OC) fusion and instrumentation in young children are unknown. Anecdotal reports have raised concerns regarding altered growth and alignment of the cervical spine after surgical intervention. The purpose of this study was to determine the long-term effects of these surgeries on the growth and alignment of the maturing spine. METHODS A multiinstitutional retrospective chart review was conducted for patients less than or equal to 6 years of age who underwent OC or AA fusion with rigid instrumentation at 9 participating centers. All patients had at least 3 years of clinical and radiographic follow-up data and radiographically confirmed fusion. Preoperative, immediate postoperative, and most recent follow-up radiographs and/or CT scans were evaluated to assess changes in spinal growth and alignment. RESULTS Forty children (9 who underwent AA fusion and 31 who underwent OC fusion) were included in the study (mean follow-up duration 56 months). The mean vertical growth over the fused levels in the AA fusion patients represented 30% of the growth of the cervical spine (range 10%–50%). Three different vertical growth patterns of the fusion construct developed among the 31 OC fusion patients during the follow-up period: 1) 16 patients had substantial growth (13%–46% of the total growth of the cervical spine); 2) 9 patients had no meaningful growth; and 3) 6 patients, most of whom presented with a distracted atlantooccipital dislocation, had a decrease in the height of the fused levels (range 7–23 mm). Regarding spinal alignment, 85% (34/40) of the patients had good alignment at follow-up, with straight or mildly lordotic cervical curvatures. In 1 AA fusion patient (11%) and 5 OC fusion patients (16%), we observed new hyperlordosis (range 43°–62°). There were no cases of new kyphosis or swan-neck deformity, evidence of subaxial instability, or unintended subaxial fusion. No preoperative predictors of these growth patterns or alignment were evident. CONCLUSIONS These results demonstrate that most young children undergoing AA and OC fusion with rigid internal fixation continue to have good cervical alignment and continued growth within the fused levels during a prolonged follow-up period. However, some variability in vertical growth and alignment exists, highlighting the need to continue close long-term follow-up.

Abstract Purpose It has been established that the infection with SARS-CoV-2 may cause an impairment of chemosensory function. However, there is little data on the long-term effects of SARS-CoV-2 infection on chemosensory function. Methods Twenty three SARS-CoV-2-positive patients diagnosed in spring 2020 with subjective hyposmia (out of 57 positive patients, 40.3%) were compared to SARS-CoV-2-positive patients without hyposmia (n = 19) and SARS-CoV-2-negative patients (n = 14). Chemosensory function was assessed by the Brief Smell Identification Test (BSIT), Taste Strips (TS), Visual Analogue Scales (VAS), and the SNOT-22. The initial cohort with hyposmia were also examined at 8 weeks and 6 months after initial examination. Results There were no differences between the SARS-CoV-2-positive cohort without hyposmia and negative controls in terms of BSIT (8.5 ± 2.6 vs. 10.2 ± 1.8), TS (3.4 ± 0.6 vs. 3.9 ± 0.3) or VAS (2.1 ± 1.3 vs. 1.1 ± 0.5); yet the SNOT-22 was significantly elevated (27.7 ± 11.2 vs. 16.4 ± 10.8). The SARS-CoV-2-positive group with hyposmia performed significantly poorer in BSIT (4.0 ± 1.7 vs. 8.5 ± 2.6/10.2 ± 1.8), TS (2.6 ± 1.3 vs. 3.4 ± 0.6/3.9 ± 0.3), and VAS (7.9 ± 2.2 vs. 2.1 ± 1.3/1.1 ± 0.5) compared to both control groups. At week 8 and month 6 control, six and five patients, respectively, still suffered from subjectively and objectively impaired chemosensory function. The other patients had recovered in both respects. Conclusion SARS-CoV-2 patients with subjectively impaired chemosensory function regularly perform poorly in objective measurements. About 70% of patients suffering from olfactory dysfunction in SARS-CoV-2 quickly recover—the rest still suffers from considerable impairment 6 months after infection.

AbstractObjectivesTo evaluate the long-term effects of the Schoolgruiten Project, a Dutch primary school-based intervention providing free fruit and vegetables (F&V). In addition, we assessed whether children’s appreciation of the project mediated these intervention effects.Design and methodsParticipating schoolchildren (mean age 9·9 years at baseline) and their parents completed parallel questionnaires at baseline, at 1-year and at 2-year follow-up, including questions on usual F&V intake of the child, potential behavioural determinants, their appreciation of the project and general demographics. Primary outcomes were usual F&V intakes as assessed by parent and child self-reported food frequency measures. Secondary outcome measures were taste preference, knowledge of daily recommendations, availability and accessibility for fruit intake. Multilevel linear regression analyses were used to assess differences at second follow-up adjusted for baseline values between control and intervention groups.SubjectsReports were available for 346 intervention children (148 parents) and 425 control children (287 parents).ResultsBoth child and parent reports indicated that the intervention group had a significantly higher fruit intake at 2-year follow-up (difference, servings/d: 0·15; 95 % CI 0·004, 0·286 for child reports; 0·19; 95 % CI 0·030, 0·340 for parent reports). No significant effects on vegetable intake were observed. Significant positive intervention effects were also found for knowledge of fruit recommendations among boys. Some evidence was found for partial mediation analyses of the effects on fruit intake.ConclusionThe present study indicates that the Schoolgruiten scheme was effective in increasing children’s fruit intake and that appreciation of the project partially mediated this effect.

Binaural Hearing Aids

AbstractConservative treatment for otitis media with effusion (OME) led us to consider the use of hearing aids as a way of managing the associated hearing loss. This study aimed to assess the compliance of patients and acceptance of hearing aids for the management of children with OME.Thirty-nine children who had been given binaural hearing aids to manage OME were assessed at routine follow-up after six months. A clinician who did not prescribe the aid administered a questionnaire to assess compliance, change in symptoms and acceptance of the aids.Thirty-eight parents thought the aids were easy to use and 25 (66 per cent) were completely satisfied with the management. Aided hearing improved by a mean of 17 dB (Range 10–30) over three frequencies, 0.5, 1.0, 2.0 Khz and all parents reported subjective hearing improvement in their children. The stigma of an aid was reported as minimal under the age of seven.Hearing aids provide a non-invasive way of managing the problems associated with OME which is acceptable to certain parents and children. Long-term effects of using aids need to be evaluated before they can be recommended.
