PROCEDURE: Survivors of childhood ALL aged 4-18 years who had completed chemotherapy for 2 years or more were evaluated for VIPN using both the clinical Total Neuropathy Score (cTNS) and nerve conduction studies. Motor function and quality of life of the survivors were assessed via the Bruininks-Oseretsky Test of Motor Proficiency Brief Form, Second Edition (BOT-2 Brief Form) and the Paediatric Quality of Life version 4.0 Generic Core Scales (PedsQL4.0) questionnaire, respectively.
RESULTS: One hundred and one survivors with a duration of follow-up ranging from 2.0 to 10.3 years were recruited. Twenty-seven (26.7%) had abnormal cTNS scores and 69 (68.3%) had electrophysiological evidence of neuropathy. Of these, 16 (15.8%) had combined clinical and electrophysiological neuropathy (VIPN). Those previously treated on the intermediate- or high-risk treatment stratification arms had a higher risk of developing VIPN (67.3 vs. 32.7%; odds ratio [OR]: 9.06, 95% confidence interval [CI]: 1.14-71.86; P = 0.014). Survivors with VIPN had significantly lower quality of life scores in the physical (P = 0.024) and social domains (P = 0.039) compared with peers without VIPN, but no association with poorer motor function was observed.
CONCLUSIONS: Sixteen percent of ALL survivors had VIPN. VIPN should be increasingly recognised as a late effect of chemotherapy, as it significantly affects physical and social function quality of life.
INTRODUCTION: Carpal tunnel syndrome (CTS) has been described as the most common compression neuropathy. Many modalities exist for conservative treatment. Efficacy of each modality has been described in the literature. However, the effectiveness of combination of these modalities is not well established. The purpose of this study is to assess the short-term clinical outcome of conservative treatment for CTS comparing orthosis alone with combination of orthosis, nerve/tendon gliding exercises, and ultrasound therapy.
METHODS: Forty-one patients who presented to Upper Limb Reconstructive and Microsurgery Clinic, University Malaya Medical Centre with CTS and positive electrodiagnostic study were recruited. Fifteen patients had bilateral CTS. Fifty-six wrists were equally randomized to orthosis alone and a combined therapy of orthosis, nerve/tendon gliding exercise, and ultrasound therapy. All patients were required to complete the Boston Carpal Tunnel Questionnaire during the first visit and 2 months after treatment.
RESULTS: Both the orthosis and combined therapy groups showed a significant improvement in symptoms and function after treatment. The mean difference of symptoms in the orthosis group was 0.53; 95% confidence interval [CI]: 0.23-0.83 (P = .001) and in the combined therapy group was 0.48; 95% CI: 0.24-0.72 (P
METHODS: We prospectively recruited 17 GBS patients and 17 age and gender-matched controls. Serial studies of their nerve conduction parameters and nerve ultrasound, documenting the cross-sectional areas (CSA), were performed at admission and repeated at several time points throughout disease course.
RESULTS: Serial nerve ultrasound revealed significantly enlarged CSA in median, ulnar and sural nerves within the first 3 weeks of disease onset. Longitudinal evaluation revealed an improvement in the nerve CSA with time, reaching significance in the ulnar and sural nerves after 12 weeks. There was no significant difference between the demyelinating and axonal subtypes. There was also no significant correlation found between nerve CSA and neurophysiological parameters or changes in nerve CSA and muscle strength.
CONCLUSION: In GBS, serial studies of peripheral nerve ultrasound CSA are helpful to detect a gradual improvement in the nerve size.
SIGNIFICANCE: Serial nerve ultrasound studies could serve as a useful tool in demonstrating nerve recovery in GBS.
