新生儿先天性高胰岛素血症3 例报告并文献复习

目的探讨新生儿先天性高胰岛素血症(CHI)发病机制、临床特征、基因诊断和治疗。方法回顾分析3例CHI新生儿的临床资料,并复习相关文献。结果 3例男性患儿分别在出生后15分钟至1小时内出现反复低血糖。2例患儿行全外显子基因检测,发现ABCC8基因杂合突变,1例行KCNJ11基因检测未发现变异。3例患儿均对二氮嗪治疗有效,出院1个月后电话随访血糖正常。检索文献,11种基因ABCC8、KCNJ11、GLUD1、GCK、HADH、UCP2、SLC16A1、HNF4A、HNF1A、HK1和PGM1变异与CHI相关。不同基因型的临床表现、药物反应及预后有显著差异。结论 CHI是一种单基因遗传病,基因检测有助诊断和治疗。     

单孔加一孔联合ERAS在高位直肠及乙状结肠癌中的应用

目的 探讨单孔加一孔腹腔镜手术联合 ERAS 治疗高位直肠及乙状结肠癌的近期疗效。方法 回顾性分析 2017 年 11 月至2018 年 10 月在福建省肿瘤医院胃肠肿瘤外科进行加速康复外科干预的 92 例高位直肠及乙状结肠癌患者资料，根 据手术方式的不同，分为单孔加一孔手术联合快速康复外科组39 例及常规腹腔镜手术联合ERAS 组 53 例，对比两组围术 期情况。结果 两组患者基线资料无明显统计学差异（P ＞ 0.05），且在手术时间、出血量、上下切缘、清扫淋巴结数量及 并发症方面无明显统计学差异（P ＞ 0.05）。但单孔加一孔手术联合ERAS 组较常规手术联合ERAS 组，总切口长度更短 [（6.7±1.1）cm 比（8.5±1.3）cm，P=0.000]，术后首次下床时间更早 [（22.2±5.2）h 比（27.1±7.9）h，P=0.001]，首次排便 时间更早[（70.2±19.8）h比（83.1±20.4）h，P=0.005]，术后第一天C反应蛋白值更低[（43.5±28.6）mg/L比（57.2±33.2） mg/L，P=0.038]，术后住院时间更短 [（7.0±1.7）d 比（8.1±2.1）d，P=0.010]，且术后 2~4 天疼痛评分更低（P ＜ 0.05）。 结论 经验丰富的腔镜医师采用单孔加一孔手术治疗高位直肠及乙状结肠癌并联合 ERAS 干预是安全可行的，且单孔加一孔 手术可减低操作难度，具有疼痛轻、术后恢复快等优势，值得临床推广。     

Evaluation of selective attention in patients with misophonia

IntroductionMisophonia is characterized by the aversion to very selective sounds, which evoke a strong emotional reaction. It has been inferred that misophonia, as well as tinnitus, is associated with hyperconnectivity between auditory and limbic systems. Individuals with bothersome tinnitus may have selective attention impairment, but it has not been demonstrated in case of misophonia yet.ObjectiveTo characterize a sample of misophonic subjects and compare it with two control groups, one with tinnitus individuals (without misophonia) and the other with asymptomatic individuals (without misophonia and without tinnitus), regarding the selective attention.MethodsWe evaluated 40 normal-hearing participants: 10 with misophonia, 10 with tinnitus (without misophonia) and 20 without tinnitus and without misophonia. In order to evaluate the selective attention, the dichotic sentence identification test was applied in three situations: firstly, the Brazilian Portuguese test was applied. Then, the same test was applied, combined with two competitive sounds: chewing sound (representing a sound that commonly triggers misophonia), and white noise (representing a common type of tinnitus which causes discomfort to patients).ResultsThe dichotic sentence identification test with chewing sound, showed that the average of correct responses differed between misophonia and without tinnitus and without misophonia (p = 0.027) and between misophonia and tinnitus (without misophonia) (p = 0.002), in both cases lower in misophonia. Both, the dichotic sentence identification test alone, and with white noise, failed to show differences in the average of correct responses among the three groups (p ≥ 0.452).ConclusionThe misophonia participants presented a lower percentage of correct responses in the dichotic sentence identification test with chewing sound; suggesting that individuals with misophonia may have selective attention impairment when they are exposed to sounds that trigger this condition.     

原发性骶尾部脊索瘤的CT分型及征象

目的对治疗前原发性骶尾部脊索瘤(PSC)CT图像分型,并分析其CT征象,为诊断和个性化治疗提供依据。方法回顾性分析101例PSC患者治疗前的CT图像,包括肿瘤的部位、范围、大小、密度、肿瘤与邻近结构的关系。按照肿瘤的部位由上及下分为Ⅰ~Ⅳ型,并根据肿瘤侵犯的范围从小到大分为a^d亚型。采用Kruskal-Wallis H检验比较PSC各亚型的占比,并对各亚型之间进行两两比较。采用R×C列联表精确概率检验比较分型和亚型肿瘤钙化的发生率。采用单因素方差分析及LSD-t检验对各分型和亚型肿瘤的大小和密度进行分析、比较。结果101例PSC中,Ⅰ~Ⅳ型的发生率分别为17.8%、30.7%、36.6%、14.9%,a^d亚型的占比分别为9.9%、25.7%、58.4%、5.9%。各亚型的占比差异具有统计学意义(P=0.012)。c亚型明显高于a亚型(P=0.039),d亚型明显低于a亚型(P=0.036),其余各型之间无明显差异。各分型肿瘤内钙化的差异无统计学意义(P=0.233);各亚型肿瘤内钙化的差异有统计学意义(P=0.003),a^d亚型肿瘤钙化的比率逐渐增加。Ⅰ型肿瘤的左右径及上下径明显大于Ⅱ~Ⅳ型(P<0.05)。a亚型与b亚型肿瘤之间前后径的差异无统计学意义(P=0.102),b^d亚型之间前后径的差异均有统计学意义(P<0.05);不同亚型肿瘤之间的左右径、上下径之间的差异均有统计学意义(P<0.05),a亚型径线最小,d亚型径线最大。结论101例PSC中,Ⅱ、Ⅲ型最多见,肿瘤较少累及第一骶骨;各亚型中,a型较少见,c亚型最多见,d亚型最少见。肿瘤的密度与分型无关,肿瘤内钙化与亚型有关。Ⅰ型肿瘤侵犯的范围较Ⅱ~Ⅳ型广泛,a^d亚型肿瘤的径线逐渐增大,CT分型有利于判断肿瘤的范围。PSC诊断延迟现象比较明显,但很少发生远处侵犯和转移。CT图像可对治疗前PSC分型,为诊断和个性化治疗提供依据。
