OBJECT The endoscopic endonasal approach (EEA) provides a minimally invasive corridor through which the cervicomedullary junction can be decompressed with reduced morbidity rates compared to those with the classic transoral approaches. The limit of the EEA is its inferior extent, and preoperative estimation of its reach is vital for determining its suitability. The aim of this study was to evaluate the actual inferior limit of the EEA in a surgical series of patients and develop an accurate and reliable predictor that can be used in planning endonasal odontoidectomies. METHODS The actual inferior extent of surgery was determined in a series of 6 patients with adequate preoperative and postoperative imaging who underwent endoscopie endonasal odontoidectomy. The medians of the differences between several previously described predictive lines, namely the nasopalatine line (NPL) and nasoaxial line (NAxL), were compared with the actual surgical limit and the hard-palate line by using nonparametric statistics. A novel line, called the rhinopalatine line (RPL), was established and corresponded best with the actual limit of the surgery. RESULTS There were 4 adult and 2 pediatric patients included in this study. The NPL overestimated the inferior extent of the surgery by an average (± SD) of 21.9 ± 8.1 mm (range 14.7-32.5 mm). The NAxL and RPL overestimated the inferior limit of surgery by averages of 6.9 ± 3.8 mm (range 3.7-13.3 mm) and 1.7 ± 3.7 mm (range −2.8 to 8.3 mm), respectively. The medians of the differences between the NPL and NAxL and the actual surgery were statistically different (both p = 0.0313). In contrast, there was no statistically significant difference between the RPL and the inferior limit of surgery (p = 0.4375). CONCLUSIONS The RPL predicted the inferior limit of the EEA to the craniovertebral junction more accurately than previously described lines. The use of the RPL may help surgeons in choosing suitable candidates for the EEA and in selecting those for whom surgery through the oropharynx or the facial bones is the better approach.

Abstract INTRODUCTION Cranial base development plays a large role in anterior and vertical maxillary growth through age 7, and the effect of early endonasal cranial base surgery on midface growth is unknown. We present our experience with pediatric endoscopic endonasal surgery and long-term midface growth. METHODS This is a retrospective review (2000-2016). Pediatric patients were grouped by age at first endoscopic endonasal skull base surgery (<7 yo and >7 yo). Included patients had both pre- and post-operative (>1 yr) imaging. Radiologists performed measurements (Sella-Nasion distance and angles from S-N to maxilla and mandible (SNA, SNB, ANB)), which were compared to age- and sex-matched Bolton standards. Z score test was used; significance was set at P < 0.05. RESULTS >The <7 yo group had 11 patients, averaging follow-up of 5 yrs; the >7 yo group had 33 patients. Most tumors were benign; one patient with a panclival AVM was a significant outlier for all measurements. Comparing the <7 yo group to Bolton standard norms, there was no significant difference in post-operative SNA (P = 0.10), SNB (P = 0.14), or ANB (0.67). SN distance was reduced both pre- and post-operatively (SD = 1.5, P = 0.01 and P = 0.009). Sex had no significant effect. Compared to patients who had surgery in the >7 yo group, the <7 yo group demonstrated no significant difference in pre- to post-operative changes with regard to S-N (P = 0.87), SNA (P = 0.89), and ANB (P = 0.14). Tumor type (craniopharyngioma, angiofibroma, and other types) had no significant effect in either age group. CONCLUSION Though our cohort of patients with skull base tumors demonstrate some abnormal measurements before their operation, their post-operative cephalometrics fall within normal standard deviations and generally have no significant difference compared to patients who underwent operations at an older age. Therefore, there appears to be no evidence of impact of endoscopic endonasal skull base surgery on craniofacial development within the growth period studied.

Abstract Objectives There are several hypotheses on the effects of the rs1738074 T/C single nucleotide polymorphism in the TAGAP gene; however, there has been no study on Turkish pediatric patients. We aimed to investigate the association of celiac disease (CD) and type 1 diabetes mellitus (T1DM) comorbidity with the polymorphism in the TAGAP gene of Turkish pediatric patients. Methods Totally, 127 pediatric CD patients and 100 healthy children were included. We determined the polymorphism by the allele-specific polymerase chain reaction method. We used IBM SPSS Statistics version 25.0 and Arlequin 3.5.2 for the statistical analyses. The authors have no conflict of interest. Results It was determined that 72% (n=154) of only CD patients had C allele, whereas 28% (n=60) had T allele. Of the patients with celiac and T1DM, 42.5% (n=17) and 57.5% (n=23) had T and C alleles, respectively. Of the individuals in control group, 67% (n=134) had C allele, whereas 33% (n=66) had T allele. Conclusions There was no significant difference in the genotype and allele frequencies between the patient and control groups (p>0.05). There was no significant association between the disease risk and the polymorphism in our study group.

Abstract OBJECTIVE To explore the effect of group medical games on the hospitalization adaptability of pediatric patients with neuro tumor. METHODS pediatric patients with neuro tumor (age:6 to 13 years) who were treated in hospital from June to December 2019 and were hospitalized for 1 month to 2 months. 29 pediatric patients(mean age:9y) were selected as the control group and treated as usual; 26 pediatric patients(meanage:8y) were selected as the experimental group for group therapeutic play intervention. Interventions last Monday, Wednesday and Friday of each week, with an average duration of one hour. Group medical play include: medical picture book education, medical preview game, emotional games, social table games. Two groups completed self-made questionnaires at the time of admission and two weeks after admission, including: diet, sleep, compliance, and social status, hospital adaptation and other related issues, two groups completed a satisfaction questionnaire after two weeks of admission, recorded analysis and compared the difference of questionnaire data and satisfaction of the two groups of pediatric patients. RESULTS There was no statistical difference in age and sex between the two groups, and there was no significant difference in baseline RESULTS: The re-test results showed that the experimental group was significantly better than the control group in terms of social status, hospital adaptation, compliance and family satisfaction(p＜0.05). CONCLUSION Group medical games can effectively improve the adaptability, compliance and family satisfaction of pediatric with neuro tumor.

Purpose: To determine associations between physical activity (PA) and sport participation on HbA1c levels in children with type 1 diabetes (T1D). Method: Pediatric patients with T1D were invited to complete a PA and sport participation survey. Data were linked to their medical records for demographic characteristics, diabetes treatment and monitoring plans, and HbA1c levels. Results: Participants consisted of 71 females and 81 males, were 13 ± 3 years old with an average HbA1c level of 8.75 ± 1.81. Children accumulating 60 min of activity 3 days or more a week had significantly lower HbA1c compared to those who accumulated less than 3 days (p < 0.01) of 60 min of activity. However, there was no significant difference in HbA1c values based on sport participation groups. A multiple linear regression model indicated that PA, race, age, duration of diagnosis, and CGM use all significantly predicted HbA1c (p < 0.05). Conclusion: This study demonstrated the significant relationship between daily PA and HbA1c. Those in this sample presented with lower HbA1c values even if accumulating less than the recommended number of days of activity. Further, it was shown that sport participation alone may not be adequate enough to impact HbA1c in a similar manner.

We studied acute and chronic pain in pediatric patients who underwent thoracotomy for benign disease with a follow-up of at least three months. A telephone interview investigated about the presence of pain and the analgesic therapy in progress. The results were compared with the anesthetic technique, postoperative pain and the adequacy of pain therapy, both during the first week after surgery and at the time of interview. Fifty-six families consented to the study. The mean age of the children at surgery was 2.9 ± 4.5 years, while at the time of the interview was 6.5 ± 4.4 years. We performed different anesthetic strategies: Group A: general anesthesia (36 pts); Group B: general anesthesia and thoracic epidural (10 pts); Group C: general anesthesia and intercostal nerve block (10 pts). During the immediate postoperative period, 21 patients (37.5%) had at least one painful episode. At the time of interview, 3 children (5.3%) had moderate chronic neuropathic (burning) pain on surgical scar. There was no statistically significant difference between the type of anesthesia and the incidence and severity of acute post-operative pain. Despite its limitations, this study confirms the low incidence of chronic post-thoracotomy pain syndrome in children.

The aim of this study was to investigate oropharyngeal pressure flow dynamics during dry swallowing in ten healthy subjects. Tongue pressure (TP) was measured using a sensor sheet system with five measuring points on the hard palate, and pharyngeal pressure (PP) was measured using a manometric catheter with four measuring points. The order and correlations of sequential events, such as onset, peak, and offset times of pressure production, at each pressure measuring point were analyzed on the synchronized waveforms. Onset of TP was earlier than that of PP. The peak of TP did not show significant differences with the onset of PP, and it was earlier than that of PP. There was no significant difference between the offset of TP and PP. The onset of PP was temporally time-locked to the peak of TP, and there was an especially strong correlation between the onset of PP and TP at the posterior-median part on the hard palate. The offset of PP was temporally time-locked to that of TP. These results could be interpreted as providing an explanation for the generation of oropharyngeal pressure flow to ensure efficient bolus transport and safe swallowing.

Abstract BackgroundMany treatment decisions in children’s Orthopaedics are based on age. This study determined whether a discrepancy between chronological age (CA) and skeletal age (SA) is dependent on BMI and if overweight or obese children would have an advanced SA.Materials and Methods120 children between ages 8-17 with an adequate hand radiograph and a correlating BMI were enrolled by retrospective chart review. Stratification based on age, sex, ethnicity, and BMI percentile was performed. For each age group, 6 males and 6 females were selected with 50% of each group having an elevated BMI. Two blinded physicians independently evaluated hand radiographs and recorded the SA. Statistical analyses evaluated inter-rater reliability and any discrepancy between groups.ResultsThe final statistical analysis included 96 children. The Intraclass Correlation Coefficient for SA determined by the two reviewers was excellent at 0.95. A difference of 13 months was found between CA and SA in the elevated BMI cohort versus the non-elevated BMI cohort, (p<0.001). No significant difference was seen between CA and SA for the non-elevated cohort (p=0.72), while matching for age and sex. ConclusionChronological age and skeletal age are not always equivalent especially in pediatric patients who are overweight or obese.

OBJECTIVE When comparing endoscopic endonasal surgery (EES) and transcranial microsurgery (TCM) for adult and mixed-age population craniopharyngiomas, EES has become an alternative to TCM. To date, studies comparing EES and TCM for pediatric craniopharyngiomas are sparse. In this study, the authors aimed to compare postoperative complications and surgical outcomes between EES and TCM for pediatric craniopharyngiomas. METHODS The data of pediatric patients with craniopharyngiomas who underwent surgery between February 2009 and June 2021 at a single center were retrospectively reviewed. All included cases were divided into EES and TCM groups according to the treatment modality received. The baseline characteristics of patients were compared between the groups, as well as surgical results, perioperative complications, and long-term outcomes. To control for confounding factors, propensity-adjusted analysis was performed. RESULTS Overall, 51 pediatric craniopharyngioma surgeries were identified in 49 patients, among which 35 were treated with EES and 16 were treated with TCM. The proportion of gross-total resection (GTR) was similar between the groups (94.3% for EES vs 75% for TCM, p = 0.130). TCM was associated with a lower rate of hypogonadism (33.3% vs 64.7%, p = 0.042) and a higher rate of growth hormone deficiency (73.3% vs 26.5%, p = 0.002), permanent diabetes insipidus (DI) (60.0% vs 29.4%, p = 0.043), and panhypopituitarism (80.0% vs 47.1%, p = 0.032) at the last follow-up. CSF leakage only occurred in the EES group, with no significant difference observed between the groups (p > 0.99). TCM significantly increased the risk of worsened visual outcomes (25.0% vs 0.0%, p = 0.012). However, TCM was associated with a significantly longer median duration of follow-up (66.0 vs 40.5 months, p = 0.007) and a significantly lower rate of preoperative hypogonadism (18.8% vs 60.0%, p = 0.006). The propensity-adjusted analysis revealed no difference in the rate of recurrence, hypogonadism, or permanent DI. Additionally, EES was associated with a lower median gain in BMI (1.5 kg/m2 vs 7.5 kg/m2, p = 0.046) and better hypothalamic function (58.3% vs 8.3%, p = 0.027) at the last follow-up. CONCLUSIONS Compared with TCM, EES was associated with a superior visual outcome, better endocrinological and hypothalamic function, and less BMI gain, but comparable rates of GTR, recurrence, and perioperative complications. These findings have indicated that EES is a safe and effective surgical modality and can be a viable alternative to TCM for pediatric midline craniopharyngiomas.
