Evaluation and Treatment of Children with Primary Immune Deficiency in the Emergency Department

The potential for morbidity and mortality in patients who have PID with febrile and nonfebrile illness is extremely high. Familiarity with the clinical manifestations of PID and collaboration with a pediatric immunologist are prerequisites for optimal short-term care of these complex patients. Conservative management with empiric broad-spectrum antimicrobials, early and aggressive surgical debridement of abscesses, and admission at a tertiary pediatric care center are often indicated.     

A Combination of Speckled Lentiginous Nevus with Patch-type Blue Nevus

A peculiar case of “nevus on nevus” was reported. A 67-year-old man had had a pigmented lesion in the left hypochondrial area since birth. The clinicopathologic findings of the pigmented lesion revealed a combination of speckled lentiginous nevus and patch-type blue nevus. This case of “nevus on nevus” is not described under the term of combined nevus as is current in the literature; it was considered to be a subtype of the type II atypical blue nevus described by Kawamura.     

Road traffic noise around schools: a risk for pupil's performance?

Summary Noise levels around educational centres can negatively affect the performance of both teachers and pupils. Two public schools in Valencia, Spain, were selected for study. One of these schools was exposed to excessively high road traffic noise levels while the other was located in a relatively quiet area. The socioeconomic level of those attending the schools was very similar. A set of external and internal noise measurements were carried out, along with two different attention tests among the children. Test results were consistently better (both for tests and for children from different classrooms in each school) in the quiet school. Exposure to high traffic noise levels in the noisy school over the whole school year is a plausible determinant of these results.     

眼内异物合并外伤性白内障的联合手术治疗：附88例分析

眼内异物合并外伤性白内障是眼外伤常见的致盲原因之一,各地报告的致盲率为20%～48.9%。本文对88例眼内异物合并外伤性白内障患者采用联合手术治疗,收到较好疗效,术前视力0.05以下占85.2%,术后矫正视力0.05以下占27.3%,矫正视力0.06～1.5占73.7%,其中矫正视力0.6～1.5者占22.8%。根据异物的性质、在眼内部位和晶体损伤情况选择不同的手术方式一次联合手术摘出异物和白内障,术后采用中西药配合治疗。联合手术可提高疗效,减少术后并发症.减少手术次数,减轻病人的痛苦,缩短病程,减少医疗费用.眼科学报1993;9:216—218.     

中药空气消毒液消毒作用的实验研究

作者通过大量的基础实验和临床现场实验研究,成功研制了中药空气消毒液。研究结果证明:本品具有抗细菌,抗甲型、乙型流感病毒及单纯疱疹病毒的作角。该药液对以金黄色葡萄球菌为代表的G~+菌,以大肠杆菌、绿脓杆菌为代表的G~-菌的最小抑菌浓度为5％,最小灭菌浓度为20％,最短灭菌时间为5min。毒理试验证明长期使用此药液无毒副作用。本品在常温下保存性能稳定;对日常用品无损伤现象。临床试验结果证明本品喷雾空气消毒作用与常规紫外线照射法、过氧乙酸喷雾法基本相同。效果满意。     

Persistent bone marrow failure with dysplastic features following pentostatin therapy for hairy cell leukaemia

Myelodysplastic syndromes (MDS) have rarely been reported after treatment with nucleoside analogues, and mainly in patients who have also received alkylating agents. We report a patient who developed MDS (refractory anaemia with ring sideroblasts) after treatment with pentostatin (deoxycoformycin) alone.     

活血祛风法治疗慢性活动性乙型肝炎临床观察

用活血祛风法治疗反复发作的慢性活动性乙型肝炎７０例，总有效为９５．７％，对照组６５例健脾清热利湿法治疗，总有效率为７８。５％（Ｐ＜０．０５）．治疗组抗ＬＳＰ，ＬＭＡ，抗核抗体，类风湿因子阴转率，ＨＢｅＡｇ，抗ＨＢｃＩｇＭ，ＨＢＶ－ＤＮＡ阴转率，抗ＨＢｅ阳转率均优于对照组（Ｐ＜０．００１）。     

病房康复延伸护理对脑卒中迟缓性偏瘫患者三维步态时空参数的影响

目的:观察病房康复延伸护理对脑卒中迟缓性偏瘫患者三维步态时空参数的影响。方法:将60例脑卒中迟缓性偏瘫患者随机分为常规护理组(A组,n=30)、病房康复延伸护理组(B组,n=30)两组,予以相应的方法治疗8周,评估治疗前后两组患者三维步态时空参数。结果:与治疗前相比,治疗后两组患者的步长、步幅、步速、步频、支撑相、双支撑相等参数及B组摆动相均有不同程度的改善(P<0.05); A组摆动相和步宽及B组步宽的变化差异无统计学意义(P>0.05)。与治疗后A组比较,治疗后B组的步长、步幅、步速、步频、支撑相、双支撑相等参数改善较为明显(P<0.05),步宽和摆动相的改善差异无统计学意义(P>0.05)。结论:病房康复延伸护理能改善脑卒中迟缓性偏瘫患者三维步态时空参数,具有临床意义。
