Background Context: Exercise limitation has been described in patients with adolescent idiopathic scoliosis (AIS); however, whether the walking performance is impaired in these patients should be elucidated.
Purpose: Thus, we aimed to evaluate the physiologic responses to the incremental shuttle walk test (ISWT) in patients with AIS.
Study Design/setting: Cross-sectional study.
Patient Sample: Twenty-nine patients with AIS and 20 healthy adolescents aged between 11 and 18 years old.
Outcome Measures: Oxygen uptake (VO₂), incremental shuttle walk distance (ISWD), ΔVO₂/Δwalking velocity, ΔHR/ΔVO₂, ΔVE/ΔVCO₂, and linearized Δtidal volume (VT)/ΔlnVE, forced expiratory volume in the first second of expiration (FEV1), and forced vital capacity (FVC).
Methods: We performed two ISWTs, and the data used were acquired in the second test. We also evaluated the lung function and respiratory muscle strength through spirometry test and manovacuometry, respectively. All authors confirm that there are no conflicts of interest. To compare the means or medians of variables between patients and healthy subjects, we used the unpaired t test or Mann-Whitney U test, respectively. The correlations were assessed by Pearson or Spearman coefficients according to the distribution of the studied variables. The probability of alpha error was set at 5% for all analyses.
Results: Adolescent idiopathic scoliosis patients showed significant lower values of ISWD, VO₂, and ventilation at the end of the ISWT, as well as lower FEV₁ and FVC; they also presented significantly shallower slope of ΔVT/ΔlnVE, whereas VO₂ related significantly with ISWD (r=0.80), FVC (r=0.78), FEV₁ (r=0.73), and ΔVT/ΔlnVE (r=0.58).
Conclusions: Adolescent idiopathic scoliosis correlated to walking limitation and was associated to reduced pulmonary function and worse breathing pattern during exercise. Our results suggest that walking-based aerobic exercises should be encouraged in these patients.

Purpose: Vertebral body tethering (VBT) is a non-fusion surgical option for adolescent idiopathic scoliosis (AIS) that requires a postoperative (PO) chest tube. This study evaluates whether 48 h of PO TXA reduces chest tube (CT) drainage and retention compared to 24 h of TXA following VBT for AIS.
Methods: Consecutively treated patients with a diagnosis of AIS who underwent VBT were assessed.

Background: Adalimumab is an effective treatment for juvenile idiopathic arthritis-associated uveitis. Data are scarce on the effects of discontinuing adalimumab after control of the disease had been reached. We aimed to assess efficacy and safety of discontinuing treatment in patients with juvenile idiopathic arthritis-associated uveitis.

: Surgery for adolescent idiopathic deformities is often aimed at improving aesthetic appearance, striving for the best possible correction. However, severe and rigid scoliotic curves not only present aesthetic issues but can also compromise cardiopulmonary health and cause early neurological impairment due to spinal cord compression, posing significant risks of morbidity and mortality if untreated. Conservative treatments are ineffective for severe curves, defined by scoliotic angles over 70° and flexibility below 30% on lateral bending X-rays.

Background: Juvenile Idiopathic arthritis (JIA) is one of the most common chronic diseases in children. It still remains a challenge to treat refractory poly-articular course JIA patients, especially in Bangladesh, where patients from low socio-economic backgrounds are unable to manage biological agents. Tofacitinib is one of the alternative options to biological agents, which can be taken orally and is cost effective.
