PubMed, EMBASE and Cochrane library search engines were used to identify studies on cognitive performance in DM patients with recurrent severe hypoglycemia.Random-effects meta-analysis was performed on seven eligible studies using an inverse-variance method. Effect sizes, which are the standardized differences between the experimental group and the control group, were calculated. Of the 853 studies, 7 studies met the inclusion criteria. Compared with control subjects, the adult DM patients with episodes of recurrent severe hypoglycemia demonstrated a significantly lowered performance on memory in both types of DM patients, and poor performance of processing speed in type 2 DM patients. There was no significant difference between adult DM patients with and those without severe hypoglycemia in other cognitive domains such as general intelligence,executive function, processing speed and psychomotor efficiency. Our results seem to confirm the hypothesis that cognitive dysfunction is characterized by worse memory and processing speed in adult DM patients with a history of recurrent severe hypoglycemia, whereas general intelligence, executive function,and psychomotor efficiency are spared.展开更多
特发性炎性肌病(idiopathic inflammatory myopathy,IIM)是以亚急性或慢性进行性发展的四肢近端肌无力为主要表现的自身免疫性疾病,主要包括皮肌炎(dermatomyositis,DM)、多发性肌炎(polymyositis,PM)、包涵体肌炎(inclusion body myosi...特发性炎性肌病(idiopathic inflammatory myopathy,IIM)是以亚急性或慢性进行性发展的四肢近端肌无力为主要表现的自身免疫性疾病,主要包括皮肌炎(dermatomyositis,DM)、多发性肌炎(polymyositis,PM)、包涵体肌炎(inclusion body myositis,IBM)、免疫坏死性肌病。其主要临床表现为躯干、对称性四肢近端肌肉、颈部和/或咽部肌无力,DM患者可有眶周、关节伸面皮疹。IIM除肌肉受累外,其他器官亦可受累,其中以肺脏较为常见,而自发性腹膜后出血则是IIM罕见且严重并发症。本文报道1例DM合并自发性腹膜后出血,并进行相关文献复习,以便临床能早期发现并及时诊治。展开更多

Studies on cognitive performance of OSAS children treated with or without AT were identified by searching the Pubmed, EMBASE and Cochrane library. A meta-analysis was conducted to analyze the literature. The random-effects model was used to evaluate 11 eligible studies using an inverse-variance method. The neuropsychological test results of 4 cognitive domains(general intelligence, memory, attention-executive function and verbal ability) were obtained and analyzed. By comparison of cognitive function between OSAS children and healthy controls, the effect sizes of each domain were achieved as follows: general intelligence, –0.5(P<0.0001); memory, –0.18(P=0.02); attention-executive function, –0.21(P=0.002); and verbal ability, –0.48(P=0.0006). The effect sizes of general intelligence, memory, attention-executive function, and verbal ability after AT compared to baseline level were –0.37(P=0.008), –0.36(P=0.0005), –0.02(P=0.88), and –0.45(P=0.009), respectively. Comparing the cognitive ability between OSAS children after AT and healthy controls showed that the effect sizes were –0.54(P=0.0009), –0.24(P=0.12), –0.17(P=0.35), and –0.45(P=0.009) in general intelligence, memory, attention-executive function, and verbal ability, respectively. Our results confirmed that OSAS children performed worse than healthy children in terms of the 4 cognitive domains investigated. After 6–12 months of observation, significant improvement in attention-executive function and verbal ability were found in OSAS children treated with AT compared to their baseline level; restoration of attention-executive function and memory were observed in OSAS children after AT in comparison to healthy controls. Further rigorous randomized controlled trials should be conducted to obtain definitive conclusions.展开更多
