Abstract

:Hemophilic ankle arthropathy features joint pain, impaired postural control, and abnormal weight-bearing pattern. This study was designed to investigate the effects of pulsed Nd:YAG laser on pain, postural stability, and weight-bearing pattern in children with hemophilic ankle arthropathy. Forty children diagnosed with hemophilia type A (age, 8-16 years) were randomly allocated to either the treatment group (n = 20) who received a three-phase active therapy with pulsed Nd:YAG laser thrice/week (total energy was 1500 J) plus a physical exercise program for four consecutive weeks, or the placebo group (n = 20) who received placebo laser plus the physical exercise program. Pain, postural control (i.e., directional control [DC], endpoint excursion [EE], center-of-gravity movement velocity [CoG-MV], and maximum excursion [MXE]), and weight-bearing pattern (i.e., pressure peaks of the hindfoot [PP-HF] and forefoot [PP-FF], and the foot contact area [FCA]) were assessed pre- and post-treatment. The treatment group showed greater improvement in pain (P = .004), DC (P = .02), EE (P = .003), and CoG-MV (P = .003) compared to the placebo group. However, there was no statistically significant difference between both groups regarding the MXE (P = .15). In addition, the treatment group achieved favorable improvements in PP-HF (P = .003), PP-FF (P = .027), and FCA (P = .002) relative to the placebo group. Pulsed Nd:YAG laser is a potentially effective therapy for pain relief, postural control enhancement, and weight-bearing pattern adjustment in children with hemophilic ankle arthropathy.

摘要

: 血友病性踝关节病变以关节疼痛、姿势控制障碍和负重模式异常为特征。本研究旨在探讨脉冲Nd:YAG激光对血友病性踝关节疾病患儿疼痛、姿势稳定性和负重方式的影响。40名诊断为a型血友病的儿童 (年龄8-16岁) 被随机分配到接受脉冲Nd:YAG激光三期积极治疗的治疗组 (n = 20),每周3次 (总能量为1500 J)。加上连续四周的体育锻炼计划,或安慰剂组(n = 20) 谁接受安慰剂激光加体育锻炼计划。疼痛,姿势控制 (i.e.,方向控制 [DC] 、终点偏移 [EE] 、重心移动速度 [CoG-MV] 和最大偏移 [MXE]) 和负重模式 (i.e.,后足 [pp-hf] 和前足 [pp-ff] 的压力峰值,以及足部接触区域 [FCA])在治疗前和治疗后进行评估。与安慰剂组相比,治疗组在疼痛 (P = .004) 、DC (P = .02) 、EE (P = .003) 和cog-mv (P = .003) 方面显示出更大的改善。然而,关于MXE,两组之间没有统计学显著差异 (P = .15)。此外,相对于安慰剂组,治疗组在pp-hf (P = .003) 、pp-ff (P = .027) 和FCA (P = .002) 方面实现了有利的改善。脉冲Nd:YAG激光是一种潜在有效的疗法,用于血友病性踝关节疾病患儿的疼痛缓解、姿势控制增强和负重模式调整。

METHODS::Vancomycin (VCM) has been reported to elicit adverse cutaneous drug reactions. However, VCM-associated purpuric drug eruption has not been reported yet, except leukocytoclastic vasculitis. A 16-year-old Japanese girl was admitted with a respiratory infection. We initiated intravenous administration of VCM. After the start of treatment, impalpable purpuric eruption appeared on her trunk. The eruption gradually extended to her neck, legs, and arms. Skin biopsy showed vasculitis with lymphocyte infiltration in the superficial dermis. A drug lymphocyte stimulation test yielded positive results for VCM. Her cutaneous symptoms rapidly reversed after the withdrawal of VCM. To the best of our knowledge, this is the first reported case of VCM-associated purpuric drug eruption, which differs from leukocytoclastic vasculitis. We recommend that VCM-associated purpuric drug eruption should be considered in the differential diagnosis during the administration of VCM, and a drug lymphocyte stimulation test may be useful for assessment of pathogenesis.

METHODS::The cardinal biological role of vitamin K is to act as cofactor for the carboxylation of a number of vitamin K-dependent proteins, some of which are essential for coagulation, bone formation and prevention of vascular calcification. Functional vitamin K deficiency is common and severe among dialysis patients and has garnered attention as a modifiable risk factor in this population. However, no single biochemical parameter can adequately assess vitamin K status. For each biological function of vitamin K, the degree of carboxylation of the relevant vitamin K-dependent protein most accurately reflects vitamin K status. Dephosphorylated uncarboxylated matrix Gla protein (dp-ucMGP) is the best biomarker for vascular vitamin K status when cardiovascular endpoints are studied. Dp-ucMGP levels are severely elevated in haemodialysis patients and correlate with markers of vascular calcification and mortality in some but not all studies. The aetiology of vitamin K deficiency in haemodialysis is multifactorial, including deficient intake, uraemic inhibition of the vitamin K cycle and possibly interference of vitamin K absorption by phosphate binders. The optimal vitamin K species, dose and duration of supplementation to correct vitamin K status in dialysis patients are unknown. Dp-ucMGP levels dose-proportionally decrease with supraphysiological vitamin K2 supplementation, but do not normalize even with the highest doses. In the general population, long-term vitamin K1 or K2 supplementation has beneficial effects on cardiovascular disease, bone density and fracture risk, and insulin resistance, although some studies reported negative results. In haemodialysis patients, several trials on the effects of vitamin K on surrogate markers of vascular calcification are currently ongoing.

METHODS::Immune thrombocytopenia (ITP) is an autoimmune disease with a mild to severe risk of bleeding complications. First line treatment includes corticosteroids, immunoglobulins, or other. In this large cohort study, first-line strategies for treatment-naive adult primary ITP was studied in a real-world setting. Records from all adult ITP patients who received first-line treatment between January 2010 and December 2017 at Qilu Hospital were reviewed retrospectively (n = 699). During the study period, 271 patients were treated with high-dose dexamethasone (HDD) and 289 patients were treated with conventional prednisone (alone or in combination with other drugs). Initial responses were similar for the two groups (88.56% vs. 86.51%, P = 0.462), but patients in the HDD group responded earlier than the prednisone group (3 days vs. 5 days, P < 0.001). The sustained response (SR) at 6 months was lower in the HDD group than in the prednisone group (35.4% vs. 47.1%, P = 0.040). However, the SR at 12 months and at the end of our follow-up were not significantly different between the groups. Overall duration of response (DOR) in the prednisone group was longer than in the HDD group throughout the follow-up period (P = 0.007). However, the incidence of SR and overall DOR were not significantly different between the HDD group and the prednisone 3 months group (prednisone terminated within 3 months). The presence of anti-GPIb-IX autoantibodies was a predictive factor for a poor initial response to corticosteroids therapy (P < 0.05). However, neither of the two antiplatelet autoantibodies were correlated with the opportunity to achieve SR and overall DOR in both groups throughout the follow-up period (P > 0.05). Adverse events were more frequent and long-lasting in the prednisone group. Our study showed that HDD provided an effective and more rapid response as initial treatment of ITP, with comparable long-term prognosis and better tolerance when compared with conventional PDN (less than 3 months) in the real-world setting.
