Benign intracranial hypertension and recombinant growth hormone therapy in Australia and New Zealand
PA Crock JD McKenzie AM Nicoll NJ Howard W Cutfield LK Shield G Byrne 《Acta paediatrica (Oslo, Norway : 1992)》1998,87(4):381-386
Benign intracranial hypertension (BIH) is reported in three children from Australia and one from New Zealand, who were being treated with recombinant human growth hormone (rhGH). Three males and one female, aged between 10.5 and 14.2 y, developed intracranial hypertension within 2 weeks to 3 months of starting treatment. A national database, OZGROW, has been prospectively collecting data on all 3332 children treated with rhGH in Australia and New Zealand from January 1986 to 1996. The incidence of BIH in children treated with growth hormone (GH) is small, 1.2 per 1000 cases overall, but appears to be greater with biochemical GHD (<10IUml -1 ), i.e. 6.5/1000 (3 in 465 cases), relative risk 18.4, 95% confidence interval 1.9-176.1, than in all other children on the database. The incidence in patients with Turner's syndrome was 2.3/1000 (1 in 428 cases). No cases in patients with partial GHD (10–20 IUml -1 ) or chronic renal failure were identified. Possible causative mechanisms are discussed. The authors'practice is now to start GH replacement at less than the usual recommended dose of 14IUm-2 week-1 in those children considered to be at high risk of developing BIH. Ophthalmological evaluation is recommended for children before and during the first few months following commencement of rhGH therapy and is mandatory in the event of peripheral or facial oedema, persistent headaches, vomiting or visual symptoms. The absence of papilledema does not exclude the diagnosis. 相似文献

To evaluate the value of clinical trials on intratympanic steroid therapy in Ménière’s disease (MD), idiopathic sudden sensorineural hearing loss (ISSNHL) and rapidly progressive sensorineural hearing loss (RPSNHL). Medline and Pubmed databases from 1966 to present were searched for clinical studies on intra- or transtympanic (cortico)steroid therapy of MD, ISSNHL and RPSNHL. Results were cross-checked with additional databases to obtain a complete data set. Clinical trials were evaluated on the basis of comparability, internal and external validity. Articles were judged using the following questions: was a randomised double-blind controlled trial performed? Which criteria were used to confirm the diagnosis of MD, ISSNHL, RPSNHL? Which therapy was evaluated? How long was the follow-up? Which criteria were used to evaluate the results? Reliable evidence on the efficiency, optimum dosage and administration schedule of intratympanic steroid therapy in MD, ISSNHL and RPSNHL is lacking, therefore further investigation is required. 相似文献

Molecular evolutionary relationships of enteroinvasive Escherichia coli and Shigella spp 总被引:2,自引:0,他引:2
Enteroinvasive Escherichia coli (EIEC), a distinctive pathogenic form of E. coli causing dysentery, is similar in many properties to bacteria placed in the four species of Shigella. Shigella has been separated as a genus but in fact comprises several clones of E. coli. The evolutionary relationships of 32 EIEC strains of 12 serotypes have been determined by sequencing of four housekeeping genes and two plasmid genes which were used previously to determine the relationships of Shigella strains. The EIEC strains were grouped in four clusters with one outlier strain, indicating independent derivation of EIEC several times. Three of the four clusters contain more than one O antigen type. One EIEC strain (an O112ac:H- strain) was found in Shigella cluster 3 but is not identical to the Shigella cluster 3 D2 and B15 strains with the same O antigen. Two forms of the virulence plasmid pINV have been identified in Shigella strains by using the sequences of ipgD and mxiA genes, and all but two of our EIEC strains have pINV A. The EIEC strains were grouped in two subclusters with a very low level of variation, generally not intermingled with Shigella pINV A strains. The EIEC clusters based on housekeeping genes were reflected in the plasmid gene sequences, with some exceptions. Two strains were found in the pINV B form by using the ipgD sequence, with one strain having an mxiA sequence similar to the divergent sequence of D1. Clearly, EIEC and Shigella spp. form a pathovar of E. coli. 相似文献

The National Athletic Injury/Illness Reporting System is a national surveillance system created from several workshops at which physicians, athletic trainers, and sports administrators shared their ideas for obtaining meaningful data. The primary objective was to provide a feasible and inexpensive mechanism for the continuous collection and analysis of information on sports-related injuries. Additionally, the project offers institutions and agencies a useful system of recordkeeping. NAIRS collects data on a wide range of sports, however, this report clarifies the risk of injury for high school and college football. Presented are data on neurotrauma, meniscus/knee sprains, and ankle sprains. Playing surface, surface hardness, surface friction, and shoe-turf interface were also examined. It was concluded that no helmet type or brand was associated with unusually high levels of risk. Artificial surfaces did not constitute an additional risk of significant concussion. An association between playing surface and the risk of knee and ankle injuries was observed. J Orthop Sports Phys Ther 1979;1(2):103-108. 相似文献

Abstract The purpose of this study was to ascertain the body disposal preferences of college students at The Pennsylvania State University, and to identify factors related to their choice in order to draw implications to strengthen death education programming. In this study, 184 undergraduate students were asked to complete a short questionnaire regarding body disposal preferences and related concerns. A variety of independent variables were identified. Significant interrelationships were found between the independent variables; primary reason for choice of body disposal, religious affiliations, perceived reasonable costs, desire to utilize the services of a funeral director, and the dependent variable, choice of body disposal. These data also indicate that college age students prefer non-traditional burial modalities. The educational implication of these findings are discussed. 相似文献
