Hyponatremic coma under oxcarbazepine therapy.

Oxcarbazepine (OXC) is considered to be a promising new antiepileptic drug with similar efficacy and better tolerability compared to carbamazepine (CBZ). However, hyponatremia is supposed to occur even more often than with CBZ. We report on a patient who developed hyponatremic coma under OXC with a serum sodium level of 115 mmol/l, the second published case of OXC-induced hyponatremia with serious clinical adverse effects.     

小型猪在异种移植中的应用前景

目的 建立狂犬病病毒感染动物疾病模型.方法 狂犬病病毒CVS-B2C毒株以10LD50剂量腿部肌肉注射接种4～6周龄的BALB/c小鼠,0.2 mL/只,于BSL2实验室负压IVC设备内饲养观察,并对其模型进行评价.结果 小鼠接种狂犬病病毒后一周左右就出现临床症状,表现为饮食量下降,毛皮慢慢失去原先的光泽,体重下降,并出现麻痹等症状,进而死亡,部分小鼠出现躁狂的症状或抽搐性和强直性痉挛,而对照组小鼠则表现正常.DFA法检测结果:感染上狂犬病毒的小鼠脑组织涂片中出现特异性荧光抗体染色反应,而对照组动物的小鼠脑组织涂片未出现荧光抗体染色反应.RT-PCR法检测结果:从感染小鼠脑组织标本中提取病毒RNA,引物扩增出的目的 基因片段,大小约为1kb,为N蛋白.免疫组化法检测结果:感染狂犬病毒的小鼠脑切片显示出棕色阳性颗粒,对照组小鼠脑切片染色阴性.病理检测结果:HE染色可见感染小鼠脑组织炎性细胞浸润.神经细胞胞质内出现内基体以及神经细胞退行性病变.结论 成功的复制出小鼠狂犬病病毒感染模型,为研究和控制狂犬病奠定了基础.     

Regional Variation and Use of Exception Letters for Cadaveric Liver Allocation in Children with Chronic Liver Disease

The Pediatric End-Stage Liver Disease (PELD) score was designed to reduce subjectivity in liver allocation and to advantage patients with a higher probability of waiting list mortality. The aims of this study were to determine the impact of PELD implementation for children with chronic liver disease and to assess whether PELD met its goal of standardization of liver allocation for children. This study used data reported to the United Network for Organ Sharing (UNOS) registry for children with chronic liver disease receiving primary cadaveric liver transplant between January 2000 and December 2001 (pre-PELD) and March 2002 and July 2003 (PELD). PELD reduced the percentage of children transplanted while in an intensive care unit and as status 1. A calculated PELD score was used for allocation in only 52% of recipients. Thirty percent were status 1 at transplant and PELD scores granted by exception were used for allocation in 18% of patients. There was regional variation in PELD score at allocation and use of exception scores with a significant relationship between PELD score and percentage of exception cases. Regional variation suggests that PELD has not resulted in standardization of listing practices in pediatric liver transplantation.     

Nursing leaders' and nurses' view of health

This study is part of a scientific project, 'Multidimensional Health', the main goal of which is to introduce a broad view on health into health care and nursing The purpose of this study is to examine the view of health among nursing leaders and members of caring staff and to compare it to that of patients (a previous study in the project) The study is based on K Eriksson's theory of caring and its view of the human being with a body, soul and spirit, and health as a dynamic process concerning all aspects of human life An inquiry form with open questions that brought to the fore various aspects and dimensions of health was filled in by 20 nursing leaders and was used in interviewing 49 nurses According to the results many aspects of life are contained in the concept 'health' Health is above all an experience of well-being Ways of promoting one's health are described in terms of various 'healthy' living habits and preventive measures A supporting and humane attitude is hoped for in others There is unanimity that feelings affect health Belief may have a positive influence on health The meaning of life is connected with health Even suffering is part of health In interpreting the answers we assume three dimensions of health 'Health as behaviour' connects health with living in a healthy way 'Health as being' would mean a state of health and is characterized by a search for some kind of balance in one's inner state 'Health as becoming', growing towards health, means that a person becomes whole on a higher level of integration     

Incidence of Hyperpronation in the ACL Injured Knee: A Clinical Perspective

Assessing abnormal biomechanics when treating various lower extremity pathologies provides the athlete with comprehensive management and promotes injury prevention. However, there have been few previous investigations of abnormal biomechanical forces on ligamentous pathologies of the knee. During this clinical study we investigated the incidence of hyperpronation in subjects who have had an anterior cruciate ligament (ACL) injury. Fifty subjects with a past medical history of ACL rupture and 50 subjects without a history of lower extremity pathology participated in our study. Hyperpronation of the foot and ankle complex was measured with the navicular drop test. The ACL injured subjects had greater navicular drop test scores than noninjured subjects. This suggests that hyperpronation of the foot and ankle complex may increase the risk of injury to the ACL. There is a need for further investigation into possible pre-loading stresses on knee ligaments.     

Trisomy 9 mosaicism in two girls with multiple congenital malformations and mental retardation.

Two girls with mosaicism for an extra chromosome 9 are reported. Clinical findings included growth and mental retardation, facial dysmorphism, delayed ossification, single flexion crease, gastro-oesophageal reflux in one girl, and ventricular and atrial septal defects in the other patient. These findings are compared to the other previously reported cases of trisomy 9 mosaicism.
