??Objective??To detect pathogenic genes of short stature with unknown etiology by a targeted next generation sequencing panel to analyze the correlation between genotypes and clinical phenotypes. Methods??A total of 77 children diagnosed with unexplained short stature were enrolled for the study. These children were treated in Ruijin Hospital of Shanghai Jiao Tong University from 2007 to 2015. To search for genetic variation in 187 candidate genes which were associated with growth?? we constructed a targeted next generation sequencing panel encompassing the coding regions of 187 genes. According to ACMG Guidelines??the sites of variation were determined. Sanger sequencing was used to verify the suspected pathogenic genes variation. The relationship between genotype and clinical phenotype was analyzed. Results??Including 5 pathogenic variants?? one likely pathogenic variant and one variant of uncertain significance?? we identified 7 heterozygous variants of 7 cases in 77 cases of short stature with unknown etiology. A pathogenic variant p.D2407fs of ACAN gene was found in a case with advanced bone age. There were 3 reported pathogenic variants?? including p.A72G?? p.I282V and p.P491S of PTPN11 gene?? which were diagnosed as Noonan syndrome. A case carrying known pathogenic variant COL2A1??p.R904C?? was diagnosed as Stickler syndrome. We still got one likely pathogenic variant COMP??p.D401N???? which could cause multiple epiphyseal dysplasia. There was a familial short stature of delayed bone age carrying a variant??p.S289Y?? of uncertain significance??in which the genotype was in accordance with the clinical phenotype. Conclusion??The ACAN gene defection is associated with the idiopathic short stature with advanced bone age. The likely pathogenic variant COMP??p.D401N?? may cause multiple epiphyseal dysplasia. The newly-found heterozygous varians??p.S289Y?? of GHSR gene may result in short stature??which needs further function verification.

??Objective??To analyze the clinical features and the results of genetic diagnosis in children with hypokalemic renal tubular diseases. Methods??The clinical data of 38 patients with hypokalemic renal tubular diseases were analyzed retrospectively??who were treated in Children’s Hospital Affiliated to Shanghai Jiao Tong University from Jan. 2010 to Jan. 2016. Results??Totally 38 patients with hypokalemic renal tubular diseases were enrolled in this study. There were 18 cases of renal tubular acidosis??RTA?? including 17 cases of type??RTA and 1 case of type?? RTA. There were 11 cases of Bartter syndrome??5 cases of Gitelman syndrome and 4 cases of Fanconi syndrome. The common clinical manifestations of hypokalemic renal tubular diseases included myasthenia??nausea??vomiting??polydipsia??polyurine and growth retardation. One case of Fanconi syndrome progressed to chronic Kidney disease??phase ????while the other
children had normal renal function. Glomerular proteinuria was found in 1??1 and 3 children with Bartter syndrome??Gitelman syndrome and Fanconi syndrome??respectively. Additionally??1 case with Fanconi syndrome has tubular proteinuria. However??urinary trace proteins associated with glomerular and tubular injury commonly elevated in these hypokalemic renal tubular diseases. Genetic analysis showed a new potential heterozygous mutations of ATPV0A4 in type??RTA and three heterozygous mutations of SLC12A3 in Gitelman syndrome. Conclusion??The clinical symptoms vary in patients and are featured mainly by myasthenia??nausea??vomiting??polydipsia??polyurine and growth retardation. Glomerular and tubular injuries are commonly found in hypokalemic renal tubular diseases. Moreover??genetic diagnosis may be helpful in diagnosis??treatment and genetic counseling.

??Abstract??Objective The time-effect relationship in treating postural orthostatic tachycardia syndrome ??POTS?? of children with alpha receptor agonist midodrine hydrochloride was analyzed to explore the optimum course of treatment for POTS children. Methods A total of 104 cases of the POTS children were studied from 2005 to 2011 in Peking University First Hospital. A chi-square test was used to evaluate the relationship between effect and time of medication?? and the time-effect curve was constructed. Results According to the 104 cases?? the time accumulative total efficacy for 1 month?? 2 months?? 3 months?? 4 months?? 5 months and 6 months were 19.23%?? 48.08%?? 69.23%?? 73.08%?? 74.04% and 75.96%?? respectively. The time accumulative total efficacy for 3 months was higher than that for 1 month or 2 months ??P??0.05???? but there was no difference in the efficacy among 4 months?? 5 months and 6 months treatment and with 3 months treatment. Conclusion It has the best treatment efficacy when the course of treatment for POTS children with midodrine hydrochloride is 3 months?? and prolonging the duration of treatment does not significantly improve the therapeutic effect.

血管瘤伴血小板减少综合征11例

目的总结Kasabach-Merritt综合征的的临床特点,提高对本病的认识并探讨其治疗方案。方法对2002·4-2006·3年我院收治的11例Kasabach-Merritt综合征病人的临床特点、实验室检查、治疗情况进行回顾性分析。结果11例Kasabach-Merritt综合征中,男4例,女7例,年龄8天~5岁,临床特点为不同部位、大小的血管瘤伴不同程度血小板减少及出血症状,部分伴发骨骼畸形。治疗结果为1例手术治愈,8例药物治疗临床症状改善,2例药物治疗死亡。结论Kasabach-Merritt综合征临床少见,误诊率高,出血重,病死率相对较高。依据血小板减少程度不同,采取不同治疗方案,缓解病情,以提供适时的手术时机、对本症的预后尤为重要。     

Chronic consumption coagulopathy due to an occult splenic haemangioma: Kasabach-Merritt syndrome

We report an 11-year-old girl with a 2-year histor of bruising associated with thrombocytopenia and dysfibrinogenaemia. On admission she presented with a large subcutaneous haematoma and splenomegaly and was severely anaemic. Laboratory investigations revealed signs of consumption coagulopathy. Radiological examination showed splenic, retroperitoneal and intra-ossal haemangiomas. After splenectomy, platelet count and coagulation parameters returned to normal.Conclusion Contrary to widely held views, occult visceral haemangioma can lead to Kasabach-Merritt syndrome beyond infancy and is not necessarily associated with visible cutaneous haemangioma. It should be included in the differential diagnosis of chronic thrombocytopenia at any age. Early determination of fibrinogen degradation product levels is advised in order to detect an underlying chronic consumption coagulopathy prompted by an extensive search for multifocal liaemangioma.     

Kasabach-Merritt综合征5例临床分析

目的：分析5例婴儿Kasabach-Merritt综合征（KMS）临床数据及转归。方法1993年6月-2012年2月期间我科收治的5例KMS患儿（男4例,女1例）,回顾性收集上述病例的一般资料、血常规及出凝血检查、影像学和病理学检查结果并加以分析。结果5例患儿中3例为皮下型巨大血管瘤,2例为内脏型巨大血管瘤,除1例首诊时确诊为KMS外,其余4例首诊时均存在误诊。血液检查结果提示所有患儿均存在不同程度消耗性凝血功能障碍。所有患者均给予肾上腺糖皮质激素治疗及对症支持治疗,对激素敏感者3例,激素敏感率为60％,手术治疗1例。经治疗存活4例,死亡1例,死亡原因为严重DIC伴多脏器功能衰竭。结论应提高对KMS的认识以减少误诊发生率,对婴儿难治性血小板减少伴凝血功能异常者需注意除外KMS ,不同患儿对药物的治疗反应存在个体化差异,故应针对不同情况采用个体化综合治疗方法,以提高临床诊疗效果。     

Diffuse cavernous hemangioma of the spleen with Kasabach-Merritt syndrome misdiagnosed as idiopathic thrombocytopenia in a child

Background  Most cavernous hemangiomas in the spleen are small lesions that are found incidentally and patients usually present with no symptoms. Imaging is able to detect the lesions that are considered as diagnostic evidence. But some patients with diffuse cavernous hemangioma may present with anemia, thrombocytopenia, coagulopathy and bleeding, which might be misdiagnosed as idiopathic thrombocytopenia with disseminated intravascular coagulation (DIC). Splenectomy is the most effective therapy for diffuse cavernous hemangiomas with symptoms. Methods  The history, imaging results, pathologic findings, diagnosis and treatment of a 34-month-old boy with severe petechiae were reviewed. Results  The boy was diagnosed as having refractory idiopathic thrombocytopenia (ITP) because of low platelet count and bleeding at a local hospital. He had no response to a full-dose of corticosteroid and a high-dose of immunoglobulin (2 g/kg). Huge splenomegaly and DIC were found after 7 months. Diffuse cavernous hemangioma of the spleen was highly suspected, but it was not confirmed by B ultrasound, enhanced CT or MRI. DIC and bleeding were solved by low molecular weight heparin, supplement of fibrinogen and prothrombin complex. A diffuse cavernous hemangioma involving the whole spleen was confirmed pathologically following a successful splenectomy. The boy recovered completely without any complication after the operation. Conclusions  Diffuse cavernous hemangioma of the spleen should be differentiated from ITP associated with splenomegaly. Radiological and overall physical examination should be emphasized for refractory ITP cases.
