The reliability in determining the deep fascia displacement of the upper trapezius during cervical movement: A pilot study

BackgroundRestricted shoulder fascia displacement may be an etiological factor for myofascial pain syndrome. A diagnostic ultrasound video can follow deep fascia displacement during active cervical movements. Trackers can be applied to videos to convert deep fascia displacement into data points. This study reports on assessors' reliability in evaluating direction and quantifying upper trapezius' deep fascia displacement during active cervical movements.MethodsPT-Sonographer 1 recorded deep fascia displacement of upper trapezius for three sets using HS1 Konica Minolta diagnostic ultrasound. The recording sequence used was cervical flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation. The three assessors used the tracker to determine direction of deep fascia displacement. PT-Sonographer 1 used the tracker three times in quantifying deep fascia displacement. Intraclass correlation coefficient and Kappa determined the assessors' intra-tester and inter-tester reliability.ResultsTen participants were included in the study with a mean±(SD) age of 37±(6). All the assessors had acceptable intra-tester reliability in determining deep fascia displacement on tracker (ICC≥0.40). All assessors had clinically unacceptable inter-tester reliability in determining deep fascia displacement when tracking right rotation (ICC < 0.40). PT-Sonographer 1 had clinically unacceptable intra-tester reliability in determining deep fascia displacement when tracking left rotation (ICC<0.40).ConclusionWe report clinically acceptable assessors' reliability in determining direction and total deep fascia displacement when tracking diagnostic ultrasound videos of cervical flexion, extension, and lateral flexion. Checking for reliable deep fascia displacements may distinguish MPS from non-MPS individuals increasing the utility of diagnostic ultrasound machine and tracker in clinical practice.     

Renal Neoplasia in Tuberous Sclerosis: A Study of 41 Patients

ObjectiveTo study the clinical features and identify unique renal neoplasia subtypes and their prognostic implications in individuals with tuberous sclerosis complex (TSC).Patients and MethodsThe Mayo Clinic nephrectomy registry included 37 patients with TSC diagnosed between 1970 and 2018. Four additional patients were identified from the pathology consultation and autopsy files. All available renal tumors were further characterized using immunohistochemistry and fluorescence in situ hybridization. Clinicopathologic features and follow-up were obtained from the medical record. The American Association for Cancer Research Project GENIE registry was accessed using cBioPortal for molecular profiling of angiomyolipoma (AML).ResultsA total of 276 renal tumors from 41 patients were analyzed. Renal tumors were classified into 9 distinct morphological subtypes, with AML predominating (238 [86%]). Interestingly, all these tumors acted in a benign fashion except one renal cell carcinoma with clear cells and fibromyomatous stroma and one epithelioid AML that metastasized. Molecular profiling studies revealed that epithelioid AMLs were enriched for alterations of TP53, RB1, and ATRX. Eight patients died of direct complications of TSC, including 3 of end-stage renal disease. To date, none have died of a renal epithelial neoplasm.ConclusionThe identification of unique renal neoplasia subtypes may provide important clues to establish a diagnosis of TSC, and in the somatic setting, this finding has important implications for accurate prognostication. These tumors tend to be indolent, and only 2 of 276 tumors in our study exhibited metastatic behavior. Our results support multidisciplinary management with a focus on preservation of renal function.     

续筋接骨方治疗骨折临床观察

目的研究续筋接骨方治疗骨折的临床疗效。方法选取2018年1月—2018年6月在辽宁中医药大学附属第三医院就诊的骨折患者60例,所有患者按照随机数字表法分为对照组与观察组,每组30例。观察组口服续筋接骨方联合正骨后小夹板固定治疗,对照组患者采用正骨后小夹板固定治疗。分析2组患者干预3个月后的血清骨代谢指标、骨密度、生活质量改善情况以及疗效判定。结果干预前,2组的血清Ⅰ型前胶原羧基端肽β特殊序列(β-CTX)、血清Ⅰ型前胶原氨端肽原(PINP)、骨特异性碱性磷酸酶(ALP)水平、钙、磷及骨密度比较,差异无统计学意义(P>0.05);干预后,2组的β-CTX、PINP、骨特异性ALP水平、钙、磷及骨密度较干预前改善,观察组的改善效果优于对照组,差异均有统计学意义(P<0.05)。干预前,2组的物质生活、社会功能、躯体健康以及心理健康评分比较,差异无统计学意义(P>0.05);干预后,2组的物质生活、社会功能、躯体健康以及心理健康评分较干预前升高,观察组的各项生活质量评分高于对照组,差异均有统计学意义(P<0.05)。观察组的治疗恢复率高于对照组,差异有统计学意义(P<0.05)。结论续筋接骨方可以改善骨折患者骨代谢功能及生活质量。

La consultation psychiatrique d’Yves Pélicier ou l’art de la biographie

The teaching and clinical practice of professor Yves Pélicier contributed to the international development of a psychiatry centered on the whole of the person in a humanist approach. The theoretical developments were marked by the authenticity of the practice of the therapist and its deep sense of the human being thus truly founding a School.     

Enlarged high frequency oscillations of the median nerve somatosensory evoked potential and survival in amyotrophic lateral sclerosis

ObjectiveA large N20 and P25 of the median nerve somatosensory evoked potential (SEP) predicts short survival in amyotrophic lateral sclerosis (ALS). We investigated whether high frequency oscillations (HFOs) over N20 are enlarged and associated with survival in ALS.MethodsA total of 145 patients with ALS and 57 healthy subjects were studied. We recorded the median nerve SEP and measured the onset-to-peak amplitude of N20 (N20o-p), and peak-to-peak amplitude between N20 and P25 (N20p-P25p). We obtained early and late HFO potentials by filtering SEP between 500 and 1 kHz, and measured the peak-to-peak amplitude. We followed up patients until endpoints (death or tracheostomy) and analyzed the relationship between SEP or HFO amplitudes and survival using a Cox analysis.ResultsPatients showed larger N20o-p, N20p-P25p, and early and late HFO amplitudes than the control values. N20p-P25p was associated with survival periods (p = 0.0004), while early and late HFO amplitudes showed no significant association with survival (p = 0.4307, and p = 0.6858, respectively).ConclusionsThe HFO amplitude in ALS is increased, but does not predict survival.SignificanceThe enlarged HFOs in ALS might be a compensatory phenomenon to the hyperexcitability of the sensory cortex pyramidal neurons.
