Effects of butanedione monoxime on neuromuscular transmission.

1. The amplitude of endplate potentials was increased by concentrations of butanedione monoxime (BDM, 5-20 mM) that typically caused muscle paralysis. 2. Although BDM slowed the decay of spontaneous miniature endplate currents, the effect was insufficient to explain most of the large increase in amplitude of endplate potentials. 3. The quantal content of endplate potentials was increased by BDM in a reversible, concentration-dependent manner. 4. The frequency of miniature endplate potentials was not changed by 10 mM BDM in the presence of normal or raised potassium concentrations, indicating that BDM does not change quantal content by a direct effect on calcium channels or on steady-state intracellular calcium concentration. 5. A change in the time course of the extracellularly recorded nerve terminal action potential caused by BDM was similar to the change produced by 4-aminopyridine (4-AP). 6. The increase in quantal content produced by BDM was only slightly reduced in the presence of 1 mM tetraethylammonium (TEA) but was significantly reduced in the presence of 0.5 to 1 mM 4-AP. 7. It was concluded that BDM blocks a 4-AP-sensitive potassium conductance in motor nerve terminals and, by increasing the duration of the action potential in this way, increases evoked transmitter release.     

诸暨麻疹疫苗免疫持久性研究基地一次麻疹流行情况的调查

1985年2~6月间,研究基地五个乡发生显性麻疹122例,为基地建立以来前11年病例总数的9.4倍,87.7%的病例集中在小学和幼儿园。
显性感染仅见于麻疹HI抗体<1:2者。不同原因导致麻疹HI抗体<1:2者,在暴露于自然麻疹后,原发免疫失败全表现为显性感染,继发免疫失败主要表现为隐性感染或不感染。
本次麻疹流行,再次证实当人群麻疹HI抗体阳性率在85%左右、阳性GMT为10.8左右的免疫水平时,虽有传染源输入,除个别易感者特别集中的单位可酿成较高罹患率外。不致造成大的流行。此外还观察到研究观察对象在充分暴露于自然麻疹后可获高达75%的隐性感染率,认为这对巩固和提高人群免疫水平具有积极意义,因而实行一次有效的麻疹疫苗接种在目前是可行的。     

Bilateral newborn testicular torsions]

A case of bilateral spermatic cord tension in a neonate is reported. Clinical findings are compared with those in 22 previously published cases. Obstetrical history is usually unremarkable. Torsion occurs prior to birth or immediately after birth. The two cords are involved simultaneously or successively. Edema of the scrotum is found in recent spermatic cord tension, whereas subsequently the tests are extremely hard and occasionally severely atrophied. Prognosis is poor since castration or poor testicular viability was the outcome in most cases.     

Detection of Epstein Barr virus in an hepatic leiomyomatous neoplasm in an adult human immunodeficiency virus 1-infected patient

We report the first case of a human immunodeficiency virus (HIV)-related primary hepatic leiomyoma in an adult patient. The diagnosis was made at autopsy and confirmed by immunohistochemistry. Epstein Barr virus (EBV) was identified in tumour cells by in situ hybridization. Review of the literature revealed 13 cases of visceral myogenic tumours occuring in acquired immunodeficiency syndrome children, and only 2 cases in adults. One was a spinal epidural leiomyoma, the other multiple smooth muscle tumours of the colon and adrenal gland. This is the first report of EBV in smooth muscle neoplastic cells in an HIV-infected adult patient.     

Natural history of atopic dermatitis and its relationship to serum total immunoglobulin E in a population-based birth cohort study

We investigated the natural history of atopic dermatitis (AD) in a population-based birth cohort and assessed whether children at risk of visible eczema at 5 years of age can be identified from total immunoglobulin E (IgE) levels measured at 8, 12 and 18 months. AD data collected included a whole body examination for visible eczema at 49 months (4 years) and 61 months (5 years) of age and parent completed questionnaire data throughout their early lives. Children were divided into four groups based on their natural history of early AD: persistent (AD at 1, 6, 18, 30 and 42 months, n  = 34), intermittent early onset (before 18  months of age, n  = 495), intermittent late onset (18–42 months of age, n  = 273) and unaffected ( n  = 429). Visible eczema at 5 years of age was present in 12.2% (117/957) (95% confidence interval [CI] 10.1–14.3%) of the children. Levels of total IgE at 8, 12 and 18 months of age were associated with early onset of AD, but not with AD of later onset. For all four natural history groups, the geometric mean total IgE at 12 months was higher in those who subsequently had visible eczema than those who did not. However, the degree of overlap was such that total IgE at 12 months of age was a poor predictor of eczema at age five. A cutoff point of 78 kU/l had the highest positive predictive value for visible eczema at 5 years of age of 28.6%, with a sensitivity of 12% and specificity of 95%.     

Integrating children's services in England: national evaluation of children's trusts

Background Poor co‐ordination of services can have severe consequences for disadvantaged children with complex needs. Since 2003 national and local governments in England embarked on sweeping reforms aimed at improving and integrating local health, education and social services for children. These were to be organized locally by children's trusts and piloted by 35 children's trust pathfinders. Methods This study described and compared the experience of integrating children's services in all 35 children's trust pathfinders, covering 20% of children in England. It had a prospective mixed‐methods design. Over 3 years we interviewed 147 managers and professionals working in the children's trusts, including 172 semi‐structured interviews, carried out two questionnaire surveys of the 35 children's trusts and analysed official documents. Results In most areas different agencies jointly commissioned children's services, especially for mental health, disabilities and multi‐purpose children's centres, and increasingly pooled finances. Provision of multi‐agency and multi‐professional services was increasing. Professionals generally supported these changes but found them stressful. All children's trusts appointed directors of children's services and established boards representing multiple agencies. Systems for sharing information about individual children were mostly in place but were still underused. Health services were generally less involved in joint work than were local authorities' education and social care services, with notable exceptions. Areas where local authorities and health authorities shared geographical boundaries made most progress. Some children's trusts made few changes beyond their statutory obligations. Conclusion Children's trusts enabled major changes to services in areas where local actors and organizations were motivated and empowered. In other areas the remit of children's trusts was often too broad and vague to overcome entrenched organizational and professional divisions and interests. Policymakers need to balance facilitation of change in areas with dynamic change agents with methods for ensuring that dormant areas and agencies are not left behind.     

The quality of acute stroke units on a nation-wide level: the Austrian Stroke Registry for acute stroke units

Concepts for stroke units that cover the acute phase vary. Therefore, the network of acute stroke units that is being set up in Austria in a uniform way is of general interest. This nationwide network has been established in accordance to evidence-based recommendations and prespecified criteria for available resources. The location for such a unit follows a maximum of 90-min isochrones (transport time) to the hospital. The quality of the network is currently documented and the results are reported. A nationwide stroke registry was prospectively performed on 15 stroke units that were already functional in this network. The aim was to document the quality performance of Austrian stroke units, focusing on rapid admissions, ready availability of investigations and therapies performed. Outcome measures were Barthel scale, Rankin score and percentages of complications. Between August 1998 and December 2000, 2,313 patients with ischemic stroke or with primary intracerebral hemorrhage admitted to an Austrian stroke unit within 24 h after onset of symptoms were prospectively included. Forty-three percent of the patients had a moderate or severe stroke. Fifty-seven percent of all patients were admitted to the stroke unit within 3 h after the onset of symptoms. Twenty-seven percent of these patients were brought in by ambulance accompanied by an emergency physician. Two percent of patients were admitted by helicopter. Fifty-four percent of patients had their first brain imaging within 30 min after admission, another 26% within 3 h. Intravenous thrombolysis was performed in 4.1% of patients. The overall stroke-unit mortality was about 6.8% and mortality at 3 months was 12.9%. The outcome at 3 months showed a modified Rankin Scale score of 0 or 1 in 47% of patients, denoting none or mild impairment. This network of acute stroke units is highly efficient in terms of rapid admissions, short intrahospital delays, as well as rapid use of readily available investigations. Stroke units seem to be well accepted by the general public and the medical community because our data show that all types of strokes are treated in Austrian stroke units, including severe strokes. The total number of concurrently treated acute strokes in other institutions across Austria is not known and no formal comparison with other systems of hospitalized care was undertaken, therefore further research is necessary.     

Monoclonal antibodies against respiratory syncytial virus and their use for rapid detection of virus in nasopharyngeal secretions.

We developed five monoclonal antibodies against respiratory syncytial virus. Three of these (23A3, 12A4, and 18B2) were used in an indirect fluorescent antibody test, and the results were compared with those of a similar indirect fluorescent test with commercial anti-respiratory syncytial virus serum. The results obtained with antibody 18B2 and commercial anti-respiratory syncytial virus serum were identical, whereas with antibodies 23A3 and 12A4 the incidence of positive identifications was around 50%.
