经皮椎体成形术导致巨大腹膜后血肿成功救治1例报道

经皮椎体成形术是一种安全有效的微创手术,腹膜后血肿是其罕见但严重的并发症。我们报告一例经皮椎体成形术RH阴性(熊猫血)患者术后并发巨大腹膜后血肿,经保守和输血等支持治疗,病人康复出院。脊柱医生应了解这种罕见但潜在致命的并发症,因为早期认识和及时预防是降低其发病率的基础。     

肘关节常见骨折的相关问题探讨

<正>肘关节骨折是临床常见的损伤,但因肘关节自身的结构特点,术后并发症较高,特别是处理不当时容易发生肘关节僵硬,给患者生活带来很大困难。尽管近几年肘关节治疗的热点集中在肘关节复杂骨折脱位和肘关节创伤性不稳定等方面,但就发生率而言,肱骨髁间骨折、尺骨鹰嘴骨折和     

Can radiomics improve the prediction of metastatic relapse of myxoid/round cell liposarcomas?

European Radiology - The strongest adverse prognostic factor in myxoid/round cell liposarcomas (MRC-LPS) is the presence of a round cell component above 5% within the tumor bulk. Its identification...     

Neuroanatomy of dyslexia: An allometric approach

Despite evidence for a difference in total brain volume between dyslexic and good readers, no previous neuroimaging study examined differences in allometric scaling (i.e. differences in the relationship between regional and total brain volumes) between dyslexic and good readers. The present study aims to fill this gap by testing differences in allometric scaling and regional brain volume differences in dyslexic and good readers. Object‐based morphometry analysis was used to determine grey and white matter volumes of the four lobes, the cerebellum and limbic structures in 130 dyslexic and 106 good readers aged 8–14 years. Data were collected across three countries (France, Poland and Germany). Three methodological approaches were used as follows: principal component analysis (PCA), linear regression and multiple‐group confirmatory factor analysis (MGCFA). Difference in total brain volume between good and dyslexic readers was Cohen's d = 0.39. We found no difference in allometric scaling, nor in regional brain volume between dyslexic and good readers. Results of our three methodological approaches (PCA, linear regression and MGCFA) were consistent. This study provides evidence for total brain volume differences between dyslexic and control children, but no evidence for differences in the volumes of the four lobes, the cerebellum or limbic structures, once allometry is taken into account. It also finds no evidence for a difference in allometric relationships between the groups. We highlight the methodological interest of the MGCFA approach to investigate such research issues.     

The perineal midsagittal view in male fetuses — pivotal for assessing genitourinary disorders

A wide range of genitourinary pathologies can be diagnosed in utero, from a simple vesicoureteral reflux to a more complex disorder of sexual differentiation. The prognosis and neonatal management of these conditions differ significantly. Evaluation of the fetal perineal anatomy is paramount to making the right diagnosis. The aim of this pictorial essay is to show sonographers how to acquire a perineal midsagittal view in a male fetus, and to demonstrate how this specific view allows assessment of the urethra and penis, to differentiate various genitourinary pathologies.
