Physical therapy intervention versus corticosteroid injection for lateral elbow tendinopathy. Does slow and steady win the race? - A systematic review.

Background: Lateral elbow tendinopathy is one of the most common chronic and degenerative diseases which significantly affects quality of life and the activities of daily living of a person. The following is a systematic review reporting a comparison between physical therapy intervention and corticosteroid injection for the treatment of lateral elbow tendinopathy. Method: PubMed, Web of Science, and Embase were searched using headings related to treatment options for Lateral elbow tendinopathy. The following keywords were used: lateral epicondylitis, physical therapy, and corticosteroid injection. Result: We descriptively analyzed and reviewed a total of 12 studies including a total of 1253 patients for lateral elbow tendinopathy. The physical therapy intervention included interventions like electrotherapy, manual therapy, and exercise. The studies included had an overall low to unknown risk of bias. Conclusion: Our review suggests corticosteroid injection provides beneficial short-term effects and physical therapy interventions provide intermediate to long-term effects, less additional treatment and low recurrence rate in patients with lateral elbow tendinopathy. Although high-quality randomized control trials are required in order to have a better understanding of both intervention types.

Efficacy of Teleconsultation-Based Rehabilitation in Children with Landry-Guillain-Barré Syndrome: An Open Label Randomized Controlled Trial (Tele Rehab-LGBS Trial).

OBJECTIVES: To evaluate the feasibility and efficacy of teleconsultation-based rehabilitation in children with Landry-Guillain-Barré syndrome (LGBS), measured with Medical Research Council (MRC) sum score and Hughes score. METHODS: A pragmatic, prospective, parallel open label randomized controlled trial was conducted among a total of 50 children with LGBS. The children were randomized using computer generated block randomization into 2 groups (25 in each group): Standard of care (Group A) and teleconsultation-based rehabilitation (Group B). Primary and secondary outcomes were measured with MRC sum score and Hughes score at 12- and 24-wk follow-up. RESULTS: The mean age was 6.4 ± 3.3 y; 29 (58%) were boys. Baseline MRC sum score (median, IQR), and Hughes score (median, IQR) in group A was 24 (7-31) and 5 (4-5) respectively; and in group B was 18 (9-24) and 4 (4-5) respectively. At discharge, median (IQR) MRC sum score in group A and B was 34 (28-41), and 30 (25-43) (p value = 0.31) respectively. Tele-rehabilitation was provided to group B for 24 wk with 96% compliance. At 12 wk, median MRC sum score in group A and group B were similar [48 (IQR 44-54) vs. 52 (IQR 46-60), p value = 0.08]. At 12 wk and 24 wk, median Hughes score in group A and B were similar. At 24 wk, 15 out of 23 subjects of group A and 18 out of 25 subjects of group B were ambulatory (p value = 0.61). CONCLUSIONS: Teleconsultation-based rehabilitation was feasible with a high compliance rate. The functional outcomes measured with MRC sum score and Hughes score were similar in both the groups at 12 and 24 wk follow-up. Teleconsultation-based rehabilitation has similar efficacy as physical rehabilitation.

Transcutaneous Electrical Nerve Stimulation in Management of Neurogenic bladder Secondary to Spina Bifida.

Aims: To assess the role of transcutaneous electrical nerve stimulation (TENS), alone or in combination with anticholinergic drugs in the management of neurogenic bladder (NB) in spina bifida (SB). Materials and Methods: All the consecutive patients, visiting outpatient clinic between July 2017 and December 2018, who were toilet trained and at least 1 year post-SB surgery with clinical and/or urodynamic evidence of NB, were included in the study. Out of 65 patients, 40 fulfilled the inclusion criteria and were randomised into: group A (ten patients, placebo TENS with anticholinergic agents), Group B (14 patients, TENS therapy with placebo medications) and Group C (16 patients, TENS therapy with anticholinergic medications). All the patients maintained a voiding diary and underwent assessment before and after the intervention. The study was approved by the Institutional Ethics Committee. Results: The presenting symptoms were urinary incontinence (100%), increased frequency (45%), straining during micturition (22.5%), urgency (22.5%), and hesitancy (30%). The demographic parameters were comparable in all the groups. After group specific intervention, the wet episodes/day significantly improved in Group C (P = 0.001). Similarly, the mean wet days/week also improved significantly in Group C (6.5-4.37 days/week, P = 0.01). Out of 40 patients, 29 had abnormal findings on ultrasonography before the start of the therapy. Following intervention, only two patients in Group C showed normalization of findings. On Urodynamic studies, detrusor pressure (Pdet max) decreased in all the groups; however, the patients in Group C, showed the maximum reduction (56.6 ± 11-30 ± 6.7 cm H2O). Similarly compliance (9.4 to 14.5 cm H2O, P = 0.02) and bladder capacity (68%-88% of EBC, P = 0.001) also improved significantly in Group C as compared to other 2 groups Overall, nine patients (Group A, B, and C = 1, 3, and five patients, respectively) showed detrusor instability, while post therapy, only one patient (Group B) had unstable bladder. Maximum decrease in postvoid residue (mean) was also observed in Group C (77-41 ml, P = 0.01). Conclusions: The application of TENS in NB secondary to SB is effective and its application led to improvement in symptoms, decrease in the wet episodes/day, maximum detrusor pressure, instability, bladder compliance, and capacity. TENS therapy in combination with anticholinergic agents had a better outcome as compared to monotherapy with either of the two modalities.

Deflazacort dose optimization and safety evaluation in Duchenne muscular dystrophy (DOSE): A randomized, double-blind non-inferiority trial.

BACKGROUND: US food and drug administration has recently approved deflazacort for Duchenne muscular dystrophy (DMD) and recommended the dosage of 0.9 mg/kg/d for patients aged ≥5years. However, data assessing the minimal efficacious dose and need of dose-titration based on age or disease severity is limited. OBJECTIVE: To determine whether deflazacort 0.45 mg/kg/d (proposed lower dosage) is non-inferior to 0.9 mg/kg/d among newly diagnosed patients with DMD. METHOD: A double-blinded, non-inferiority, randomized trial, conducted between December 2018 and July 2020. Newly diagnosed patient aged 5-15 years with genetic or muscle biopsy confirmed DMD and baseline 6-min walk distance (6MWD) > 150 m were screened. Patients were randomly assigned (1:1), stratified to prespecified subgroups by age (≤7years and >7years), and baseline 6MWD (≤350 m and >350 m), to receive either 0.45 mg/kg/d or 0.9 mg/kg/d regimens. The primary endpoint was the change in 6MWD, from baseline to week-24 of intervention. The trial was powered with a predefined, non-inferiority margin of 30 m. The analyses were by modified intention-to-treat (mITT). RESULT: A total of 97 patients were enrolled, 40 receiving 0.45 mg/kg/d and 45 receiving 0.9 mg/kg/d deflazacort comprised of mITT population. For primary endpoint analysis the mean (SD) change in 6MWD from baseline to week-24 was 9.7 m (41.5) in deflazacort 0.45 mg/kg/d, and 34.7 m (43.5) for 0.9 mg/kg/d. The mean difference in change in 6MWD across the group was 24.8 m (95% CI 6.7 to 43, p value 0.008). The mean difference in change in 6MWD in the subgroups of boys ≤7 years of age was 21.8 m (95% CI -0.82, 44.5, p = 0.059), with baseline 6MWD of >350 m was 19.9 m (95% CI -2.4, 42.4; p = 0.08). The incidence of combined moderate to severe treatment-related adverse events was significant in the 0.9 mg/kg/d group by week 24 (odds ratio 0.36 [95% CI, 0.14 to 0.89], p = 0.03). DISCUSSION: The efficacy of proposed low dose deflazacort in comparison to the standard dose did not meet the prespecified criteria for non-inferiority. The low dose deflazacort was non-inferior in subgroup of patients with age ≤7 years and baseline 6MWD of >350 m. TRIAL REGISTRATION: Clinical Trial Registry-India Identifier: CTRI/2019/02/017388.

Pilot study of rapamycin in patients with hormone-refractory prostate cancer.

BACKGROUND: Currently, no second-line treatment exists for hormonerefractory prostate cancer (HRPC) cases that fail docetaxel regimens. Rapamycin, an immunosuppressive macrolide, inhibits metastatic prostate tumor growth and angiogenesis in in vivo mouse models. This pilot study assessed the antitumor activity, safety, and toxicity of rapamycin in patients with HRPC. PATIENTS AND METHODS: Eligible patients had HRPC and disease progression. The initial dose of rapamycin was 0.15 mg/kg followed by 0.04 mg/kg daily without interruption. Rapamycin levels were measured every 28 days with dose adjustments of 0.04-0.06 mg/kg as necessary to maintain levels between 6-10 ng/mL. Patients were evaluated every 4 weeks for prostate-specific antigen (PSA) and safety and every 8 weeks for radiographic response. RESULTS: Thirteen patients were enrolled from January 2005 to February 2006. One was not evaluable for response. Responses were seen in 2 of 12 evaluable patients (17%). One patient experienced a 50% decrease in absolute PSA and partial radiographic response; another experienced a PSA response only. Four patients had stable disease (33%). The median progression-free survival was 4.2 months (range, 1.9-23.3 months), and overall survival was 23.3+ months (range, 1.9-34.3+ months). Diarrhea (69%), fatigue (46%), and nausea (46%) were the most common adverse events. Rapamycin was well tolerated and showed signs of antitumor activity. CONCLUSION: Rapamycin and other inhibitors of mammalian targets of rapamycin warrant further study in developing combination therapies with chemotherapy or radiation.

Vaccination of prostate cancer patients with modified vaccinia ankara delivering the tumor antigen 5T4 (TroVax): a phase 2 trial.

The attenuated vaccinia virus, modified vaccinia Ankara, has been engineered to deliver the tumor antigen 5T4 (TroVax). TroVax has been evaluated in an open-label phase 2 trial in hormone refractory prostate cancer patients in which the vaccine was administered either alone or in combination with granulocyte macrophage-colony stimulating factor (GM-CSF). The comparative safety and immunologic and clinical efficacy of TroVax alone or in combination with GM-CSF was determined. Twenty-seven patients with metastatic hormone refractory prostate cancer were treated with TroVax alone (n=14) or TroVax+GM-CSF (n=13). 5T4-specific cellular and humoral responses were monitored throughout the study. Clinical responses were assessed by quantifying prostate-specific antigen concentrations and measuring changes in tumor burden by computer-assisted tomography scan. TroVax was well tolerated in all patients with no serious adverse events attributed to vaccination. Of 24 immunologically evaluable patients, all mounted 5T4-specific antibody responses. Periods of disease stabilization from 2 to >10 months were observed. Time to progression was significantly greater in patients who mounted 5T4-specific cellular responses compared with those who did not (5.6 vs. 2.3 mo, respectively). There were no objective clinical responses seen in this study. In this study, the combination of GM-CSF with TroVax showed similar clinical and immunologic responses to TroVax alone. The high frequency of 5T4-specific immune responses and relationship with enhanced time to progression is encouraging and warrants further investigation.
