Hip Displacement in Cerebral Palsy: The Role of Surveillance

IntroductionHip displacement is common in cerebral palsy (CP) and is related to the severity of neurological and functional impairment. It is a silent, but progressive disease, and can result in significant morbidity and decreased quality of life, if left untreated. The pathophysiology of hip displacement in CP is a combination of hip flexor-adductor muscle spasticity, abductor muscle weakness, and delayed weight-bearing, resulting in proximal femoral deformities and progressive acetabular dysplasia. Due to a lack of symptoms in the early stages of hip displacement, the diagnosis is easily missed. Awareness of this condition and regular surveillance by clinical examination and serial radiographs of the hips are the key to early diagnosis and treatment.Hip surveillance programmesSeveral population-based studies from around the world have demonstrated that universal hip surveillance in children with CP allows early detection of hip displacement and appropriate early intervention, with a resultant decrease in painful dislocations. Global hip surveillance models are based upon the patients’ age, functional level determined by the Gross Motor Function Classification system (GMFCS), gait classification, standardized clinical exam, and radiographic indices such as the migration percentage (MP), as critical indicators of progressive hip displacement.ConclusionDespite 25 years of evidence showing the efficacy of established hip surveillance programmes, there is poor awareness among healthcare professionals in India about the importance of regular hip surveillance in children with CP. There is a need for professional organizations to develop evidence-based guidelines for hip surveillance which are relevant to the Indian context.

目的:探究归脾丸加减对围绝经期功血患者免疫功能、白细胞介素2(IL-2)、可溶性白细胞介素-2受体(sIL-2R)的影响。方法:选取2019年3月至2018年6月山东省济南市中西医结合医院收治的符合纳入条件的围绝经期功血患者118例作为研究对象,按照就诊顺序编号随机分为对照组和观察组,每组59例。对照组常规西医治疗,观察组加用归脾丸加减治疗,均治疗3个月。观察2组治疗前、完成治疗后T淋巴细胞亚群、IL-2、sIL-2R、凝血功能、子宫内膜厚度、激素水平、症状积分变化;完成治疗后统计治疗过程中的不良反应。结果:1)完成治疗后,2组CD3+、CD4+、CD4+/CD8+、IL-2较治疗前均显著升高,CD8+、sIL-2R则显著下降(P<0.05);完成治疗后观察组CD8+、sIL-2R显著低于于对照组,余均高于对照组(P<0.05)。2)完成治疗后2组凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、子宫内膜厚度较治疗前均显著下降(P<0.05),完成治疗后观察组以上指标均显著低于对照组(P<0.05)。3)完成治疗后2组黄体生成素(LH)、促排卵生成素(FSH)、雌二醇(E2)、孕酮(P)、血管内皮生长因子(VEGF)、碱性成纤维细胞生长因子(bFGF)较治疗前均显著下降(P<0.05),完成治疗后观察组以上指标均显著低于对照组(P<0.05)。4)完成治疗后2组月经周期、阴道出血量、阴道出血天数、神疲乏力积分较治疗前均显著下降(P<0.05),完成治疗后观察组以上指标均显著低于对照组(P<0.05)。5)完成治疗后观察组胃肠道反应、体质量增加、肝功能异常、乳房胀痛发生率均显著低于对照组,2组比较差异有统计学意义(P<0.05)。结论:归脾丸加减能提高围绝经期功血患者免疫功能,抑制IL-2、sIL-2R,改善凝血功能,从而改善症状,提高疗效。     

Male Sexual Function After Pediatric Kidney Transplantation—A Cross-sectional Nationwide Study

BackgroundData on adult sexual functioning after kidney transplantation (KTx) during childhood or adolescence are scarce.AimTo assess the long-term sexual and psychosocial quality of life after pediatric KTx.Methods29 young men (median age 27.1 years) were examined 18.7 years (median) after KTx. 56 age-matched healthy men (median age 30.0 years) served as controls.OutcomeWe studied the influence of sociodemographics, previous renal replacement therapy, current reproductive hormonal serum levels, testicular size, and data on several validated mental and physical questionnaires on participants' Derogatis Interview for Sexual Functioning self-report scores.ResultsThe KTx recipients had significantly poorer sexual functioning than their healthy peers. KTx men had less frequent sexual activity with a partner (P = .03) and poorer orgasms (P = .002) than the controls but no erectile dysfunction (P = .5).Clinical implicationsDepressive symptoms, relationship status, and longer dialysis duration predicted poor adult sexual functioning in KTx recipients, whereas age at transplantation or at the time of the study did not.Strengths & LimitationsThis study contributes extended follow-up data to the very scarce literature on adult sexual functioning in pediatric KTx recipients. Relatively small population and low participation rate limit the comprehensive data interpretation in a population-based cohort of male KTx recipients.ConclusionSexual functioning is often impaired in young men after pediatric KTx, emphasizing the need for long-term monitoring of sexual health and sexuality as important dimensions of quality of life.Tainio J, Jahnukainen T, Jalanko H, et al.

目的:应用99mTc-DTPA肾动脉显像评价Stanford不同分型主动脉夹层患者术后左、右侧肾功能及总体肾功能受损程度,帮助临床制定进一步的治疗方案,改善患者预后。方法:回顾性分析2018年3月8日至2019年7月19日,在本院核医学科行99mTc-DTPA肾动态显像的主动脉夹层术后患者48例,评价患者双肾血流灌注、总肾小球滤过率(GFR)和分肾的GFR,比较Stanford主动脉夹层A型(简称A型)患者和主动脉夹层B型(简称B型)患者之间总肾功能及分肾功能,血肌酐、血尿素氮及血尿酸水平的差异。结果:B型患者术后总GFR低于A型患者(67.5 vs.80.6 m L/min,P<0.05),其中以左肾功能受损为著(30.9 vs.40.3 m L/min,P<0.05),差异有统计学意义。结论:肾动态显像对主动脉夹层术后患者早期评价肾功能有重要价值。主动脉夹层B型患者GFR较A型减低,且左侧肾GFR减低更明显,临床可以早期采取干预措施,改善主动脉夹层患者预后。     

Effects of exogenous factors on spatial accuracy in neurosurgery

The study aimed to assess the effect of exogenous factors such as surgeon posture, surgical instrument length, fatigue after a night shift, exercise and caffeine consumption on the spatial accuracy of neurosurgical manipulations. For the evaluation and simulation of neurosurgical manipulations, a testing device developed by the authors was used. The experimental results were compared using nonparametric analysis (Wilcoxon test) and multivariate analysis, which was performed using mixed models. The results were considered statistically significant at p < 0.05. The study included 11 first-year neurosurgery residents who met the inclusion criteria. Hand support in the sitting position (Wilcoxon test p value = 0.0033), caffeine consumption (p = 0.0058) and the length of the microsurgical instrument (p = 0.0032) had statistically significant influences on the spatial accuracy of surgical manipulations (univariate analysis). The spatial accuracy did not significantly depend on the type of standing position (Wilcoxon test p value = 0.2860), whether the surgeon was standing/sitting (p = 0.1029), fatigue following a night shift (p = 0.3281), or physical exertion prior to surgery (p = 0.2845).When conducting the multivariate analysis, the spatial accuracy significantly depended on the test subject (p < 0.0001), the use of support during the test (p = 0.0001), and the length of the microsurgical instrument (p = 0.0397). To increase the spatial accuracy of microsurgical manipulations, hand support and shorter tools should be used. Caffeine consumption in high doses should also be avoided prior to surgery.
