目的:静脉注射消炎痛是早产儿动脉导管未闭的常规治疗方法,但治疗过程中常出现一些副作用,如少尿、消化道出血、脑血流灌注减少。近年来,静脉注射布洛芬已用于治疗早产儿动脉导管未闭。布洛芬治疗不会减少脑血流灌注,也不会影响胃肠道和肾脏的血流动力学。伊朗目前尚无消炎痛和布洛芬的静脉制剂供应。该研究旨在比较这两种药的口服制剂治疗早产儿动脉导管未闭的疗效和安全性。方法:36例胎龄小于34周经超声心动图确诊患有动脉导管未闭的早产儿被随机分为两组,每组18人。一组给予消炎痛口服,每次0.2 mg/kg,24 h给药 1 次,共3次。另一组给予布洛芬口服,共 3 次,间隔时间为24 h,首剂为 10 mg/kg,随后两次各 5 mg/kg。用药后观察导管闭合率、副作用、并发症及临床过程。结果:用药后布洛芬组18例患儿动脉导管都闭合(100%),而消炎痛组18例中有15例患儿动脉导管闭合(83.3%)(P>0.05)。两组疗效差异统计学无显著性意义。治疗前后两组的血清尿素氮和肌酐含量差异也无显著性意义。消炎痛组发生了3例(16.6%)坏死性小肠结肠炎,布洛芬组则无,差异有显著性意义 (P<0.05)。治疗1个月后两组成活率均为 94%(17/18)。消炎痛组1例死于坏死性小肠结肠炎,布洛芬组1例死于败血症。结论:口服布洛芬治疗早产儿动脉导管未闭和口服消炎痛治疗一样有效,而且坏死性小肠结肠炎的发生率较口服消炎痛治疗低。[中国当代儿科杂志,2007,9(5):399-403] 相似文献

静脉注射丙种球蛋白治疗早产儿感染的研究 总被引:27,自引:0,他引:27
为了探讨静脉注射丙种球蛋白(IVIG)预防及治疗早产儿感染的价值,用单向免疫琼脂扩散法检测51例出生1~3天(胎龄28~36周)的早产儿血清IgG、IgA、IgM。结果显示IgG均值随胎龄增加而升高(r=0.99,P<0.01),28~36周者<8.0g/L(28周仅4.5g/L),>36周者>8.0g/L;而IgA、IgM差异无显著意义(28~36周者IgA均值为615mg/L,>36周者为621mg/L;28~36周者IgM均值为423mg/L,>36周者为418mg/L),,故胎龄越小越有应用静脉丙种球蛋白(IVIG)的指征。30例重症感染的早产儿参考相似的孕周、体重及日龄,随机分为IVIG组及对照组各15例,均选用同类抗生素,且不用其它免疫制剂及血浆治疗,IVIG组按每天0.5~1g/kg稀释成50ml在2~3小时内静脉滴注,连用2天,IVIG组治疗1周后均值从8.2g/L升到13.5g/L(P<0.01);而对照组治疗后IgG均值仅6.7g/L。提示早产儿感染用IVIG疗效十分满意。 相似文献

新生儿脐血单个核细胞产生肿瘤坏死因子α的能力及临床意义 总被引:1,自引:0,他引:1
对30例早产儿、50例足月儿脐血单个核细胞与30例健康成年人外周血单个核细胞产生的肿瘤坏死因子α(TNFα)进行了测定。结果,早产儿、足月儿脐血单个核细胞产生的TNFα低于健康成年人,分别为0.45±0.24、0.86±0.39、1.82±0.56μg/L(x±s);早产儿脐血中单个核细胞产生的TNFα比足月儿低,而且TNFα的含量与胎龄及1分钟Apgar评分成正相关关系(r=0.37.P<0.01)。本研究提示,新生儿,特别是早产儿,不成熟的单个核细胞产生较低的TNFα,可能是新生儿免疫功能低下而易受感染的原因之一。 相似文献

There is a common progression known as the allergic march from atopic dermatitis to allergic asthma. Cetirizine has several antiallergic properties that suggest a potential effect on the development of airway inflammation and asthma in infants with atopic dermatitis. Methods. Over a two year period, 817 infants aged one to two years who suffered from atopic dermatitis and with a history of atopic disease in a parent or sibling were included in the ETAC® (Early Treatment of the Atopic Child) trial, a multi-country, double-blind, randomised, placebo-controlled trial. The infants were treated for 18 months with either cetirizine (0.25mg/ kg b.i.d.) or placebo. The number of infants who developed asthma was compared between the two groups. Clinical and biological assessments including analysis of total and specific IgE antibodies were performed. Results. In the placebo group, the relative risk (RR) for developing asthma was elevated in patients with a raised level of total IgE (≥ 30 kU/I) or specific IgE (≥ 0.35 kUA/I) for grass pollen, house dust mite or cat dander (RR between 1.4 and 1.7). Compared to placebo, cetirizine significantly reduced the incidence of asthma for patients sensitised to grass pollen (RR = 0.5) or to house dust mite (RR = 0.6). However, in the population that included all infants with normal and elevated total or specific IgE (intention-to-treat - ITT), there was no difference between the numbers of infants developing asthma while receiving cetirizine or placebo. The adverse events profile was similar in the two treatment groups. Discussion. Raised total IgE level and raised specific IgE levels to grass pollen, house dust mite or cat dander were predictive of subsequent asthma. Cetirizine halved the number of patients developing asthma in the subgroups sensitised to grass pollen or house dust mite (i.e. 20% of the study population). In view of the proven safety of the drug, we propose this treatment as a primary pharmacological intervention strategy to prevent the development of asthma in specifically sensitised infants with atopic dermatitis. 相似文献

OBJECTIVE: To ascertain the profile of cases of measles seen at a general hospital during a recent outbreak that occurred despite a measles vaccination program. METHODOLOGY: A retrospective study from January 1991 to March 1998. All patients with measles (ICD code 055. 9) seen at the emergency unit or as inpatients were included. RESULTS: There were 87 cases identified. The diagnosis was clinical in all and proven serologically in 71%. Eighty-five per cent of the cases occurred between January 1997 and March 1998. There was a bi-modal age distribution with peaks in the very young (= 18 months) and those aged 16-20 years. The majority was unvaccinated (58/87). A proportion (11/87) demonstrated vaccine failure, most likely primary failures. CONCLUSION: This changing measles epidemiology suggests lowering of herd immunity. 'Catch up' vaccinations in July- October 1997 given to school children aged 12-18 years (200 000 individuals or 82% of cohort), may have helped contain the outbreak. These results substantiated the need for a two-dose policy and 'catch-up' immunization program. 相似文献

EXCITING NEW TREATMENT APPROACHES FOR PATHYPHYSIOLOGIC MECHANISMS OF SICKLE CELL DISEASE 总被引:1,自引:0,他引:1
Vipul N. Mankad 《Fetal and pediatric pathology》2001,20(1):1-13
During the past several decades, our understanding of the complex pathophysiology of vasoocclusion associated with sickle cell disease has improved greatly. Interaction of genes, hemoglobin molecules, red cell membrane and metabolic changes, cell-cell interactions and cell-plasma interactions, red cell adhesion to vascular endothelium, activation of coagulation, and vascular reactivity play a role in vaso occlusion. Penicillin prophylaxis of pneumococcal infections and appropriate use of blood transfusions and other supportive measures improved survival of sickle cell patients. Hydroxyurea made a major impact on sickle cell therapy when it was shown to decrease acute painful episodes, acute chest syndrome, and the need for blood transfusion in adults. Significant experience in the use of hydroxyurea has been accumulated in older children. The benefits and risks of hydroxyurea for younger children and long-term risks in all patients will be evaluated in future investigations. Other promising therapies include butyrate compounds, clotrimazole, magnesium supplementation, poloxamer 188, antiadhesion agents, anticoagulant approaches, and nitric oxide. Hemopoietic transplantation remains the only curative therapy. However, several transgenic mouse models are available for studies of gene therapy or other treatment approaches on biochemical, cellular, and pathologic effects of mutant genes. 相似文献

A 21-year-old man with granular lymphocyte-proliferative disorders (GLPD) associated with chronic active Epstein-Barr virus (EBV) infection is described. Chromosomal analyses revealed several clonal abnormalities and two of them were mainly repetitious. High copy numbers of monoclonal EBV genome were also detected in the proliferative large granular lymphocytes (LGLs), indicating the monoclonal expansion of EBV-infected LGLs. The patient had an indolent course for several years, and there was no evidence of infiltrations of his bone marrow until the end stage. At autopsy, microscopic studies revealed marked infiltrations of LGL in the liver and spleen, and the infiltrating cells were NK-cell immunophenotype. The infiltrated LGLs showed latency I. 相似文献

LUTEINIZING HORMONE RECEPTOR MUTATIONS IN DISORDERS OF SEXUAL DEVELOPMENT AND CANCER 总被引:2,自引:0,他引:2
Shao-Ming Wu Ellen Werber Leschek Owen M. Rennert Wai-Yee Chan 《Fetal and pediatric pathology》2000,19(1):21-40
Human male sexual development is regulated by chorionic gonadotropin (CG) and luteinizing hormone (LH). Aberrant sexual development caused by both activating and inactivating mutations of the human luteinizing hormone receptor (LHR) have been described. All known activating mutations of the LHR are missense mutations caused by single base substitution. The most common activating mutation is the replacement of Asp-578 by Gly due to the substitution of A by G at nucleotide position 1733. All activating mutations are present in exon 11 which encodes the transmembrane domain of the receptor. Constitutive activity of the LHR causes LH releasing hormone-independent precocious puberty in boys and the autosomal dominant disorder familial male-limited precocious puberty (FMPP). Both germline and somatic activating mutations of the LHR have been found in patients with testicular tumors. Activating mutations have no effect on females. The molecular genetics of the inactivating mutations of the LHR are more variable and include single base substitution, partial gene deletion, and insertion. These mutations are not localized and are present in both the extracellular and transmembrane domain of the receptor. Inactivation of the LHR gives rise to the autosomal recessive disorder Leydig cell hypoplasia (LCH) and male hypogonadism or male pseudohermaphroditism. Severity of the clinical phenotype in LCH patients correlates with the amount of residual activity of the mutated receptor. Females are less affected by inactivating mutation of the LHR. Symptoms caused by homozygous inactivating mutation of the LHR include polycystic ovaries and primary amenorrhea. 相似文献

This report describes the cross-sectional analyses of data from the first year of a longitudinal study using questionnaire and respiratory function data over a 5 year period from a sample of rural South Australian school children. The cumulative or lifetime prevalences of respiratory symptoms were estimated in 825 rural and 1261 urban school children aged between 5 and 15 years in order to determine if the prevalence rates differed between rural and urban school children. The study found the overall cumulative prevalence of asthma and/or wheezy breathing (AWB) to be 24.1% in the rural school children compared to 27.6% in the urban school children. Most children developed AWB symptoms before the age of 7 years, with 20% reporting moderately severe symptoms and 10% having more than one attack per fortnight. The cumulative prevalence of bronchitis, loose/rattly cough (BLRC) differed significantly between the rural school children (34.1%) and urban school children (47.9%). The BLRC symptoms preceded the development of AWB in many cases. Urban school children also reported a higher prevalence of atopic conditions. 相似文献

The aim of the study was to explore psychological factors and autonomic activity in children with recurrent abdominal pain and to compare them with those in a control group of healthy children. The Personality Inventory for Children was used for assessment of developmental, emotional and psychosocial factors in 25 children with recurrent abdominal pain (age, 7-15 y). Parasympathetic and sympathetic functions in these children and in 23 healthy control subjects (age, 7-13 y) were also investigated, non-invasively using a computerized polygraph. Vagal tone (parasympathetic function) was indexed by calculation of respiratory sinus arrhythmia in beats/min. Skin conductance (sympathetic function) was recorded by the constant current method. On the Personality Inventory for Children, 16 patients had high scores on somatic concern. Several patients had scores in the clinical range for depression, withdrawal and anxiety, but the mean scores for these personality profile scales were well within the normal range of healthy children. Interestingly, there was a spike on the L (Lie)-scale for most of the patients and 15 patients had scores above or close to the clinical cut-off value. As compared with the scores in healthy children, vagal tone and sympathetic tone were normal. Conclusion: Many children with recurrent abdominal pain have scores in the clinical range for depression, withdrawal, anxiety and L-scale indicating coping problems, denial and a trend towards somatic concern that may contribute to the evolution of abdominal pain. Autonomic nerve activity was not disturbed in these children. 相似文献

Summary In two groups of infants (3–53 weeks old) skin temperatures were controlled in different areas of the trunk—i.e.: regions of sternum, lungs, heart, liver, spleen, kidneys—at different room-temperatures (group I: 21–25°C; group II: 29–32°C). Rectal temperatures of some probands in both groups also had been controlled simultaneously. A definite change in the reaction to heat was proofed in different periods of the first year of life. In higher environmental temperatures the skin temperature was almost constant at every controll-point of the skin, even in older infants. In lower environmental temperatures the skin temperatures lowered continuously with age till 7. to 9. moth. From 10. to 12. month the lowering of skin temperature discontinued. The rectal temperatures were relatively constant in all infants. Only in infants from 7. to 12. month, whose skin temperatures were controlled in lower as well as in higher environmental temperatures, a tendency to higher rectal temperatures was proofed in warmer environmental temperatures.The significance of these results is discussed.
