Four patients with the hypogonadotropic hypogonadism, five patients with hypergonadotropic hypogonadism, four patients with the central precocious puberty and one patient with isosexual peripheral precocious puberty collected successively their early-morning urine samples for 30 to 32 days.The urine β-FSH subunit was assayed with the method of ELISA, then adjusted by creatinine (Cr) concentration.Results:Comparing with their cotemporary groups, patients with the hypogonadotropic hypogonadism had lower levels of urine β-FSH, and patients with idiopathic hypergonadism had higher levels with irregular fluctuation. Meanwhile, patients with the central precocious puberty had much higher levels of urine β-FSH with irregular peaks, and patients with isosexual peripheral precocious puberty had almost normal levels. The patterns were coincident with the clinical characteristics and serum FSH levels.Conclusion: The ELISA of urine β-FSH subunit possesses a number of advantages over the RIA of serum FSH level, such as low cost, simplicity and reliability in the clinical practice. It can be used for the diagnoses of puberty disorders. In addition, it is possible and much easier, comparing with blood samples, to collect successively urine samples for research of pathophysiological dynamics of FSH secretion in puberty disorders and other reproductive dysfunction.展开更多

Although the first clinical description of a constellation of symptoms highly resembling to what currently could be diagnosed as ADHD is generally attributed to George F Still in 1902, there are scattered but significant published historical medical, scientific and non-scientific reports, much prior to Still's lectures, of what is currently conceptualized as ADHD. The present report aimed at exploring the early history of ADHD, prior to the 20^(th) century in the medical literature and in other historical sources, to provide clinicians, researchers and other professionals with a better understanding of the roots and current conceptualization of this disorder. It is possible to find clues and highly suggestive descriptions of individuals presenting symptoms resembling what is currently defined as ADHD in the literature, in paintings or in the Bible. However, the earliest medical reports of individuals with abnormal degrees of inattention, distractibility and overactivity date from the last quarter of the 18^(th) century, included in two of the first textbooks specifically on the subject of mental diseases, published by the German Melchior Adam Weikard and the Scottish Sir Alexander Crichton. During the 19^(th) century some eminent physicians from Germany, France or Great Britain, such as Charles West, Thomas C Albutt, Thomas S Clouston, William W, Ireland, John Haslam, Heinrich Neumann, or Désiré-Magloire Bourneville, among others provided clinical depictions of patients that most likely presently would be diagnosed as having ADHD. Whilst some of the children described by Still and his predecessors may have suffered from a variety of neurological and psychiatric disorders, many of these patients showed clear symptoms of ADHD and may present with comorbid disorders, as it is commonly the case in clinical practice.展开更多

DATA RETRIEVAL:We performed a bibliometric analysis of studies on spinal cord injury-induced neurogenic bladder using the Web of Science.Data retrieval was performed using key words"spinal cord injury","spinal injury","neurogenic bladder","neuropathic bladder","neurogenic lower urinary tract dysfunction","neurogenic voiding dysfunction","neurogenic urination disorder"and "neurogenic vesicourethral dysfunction". SELECTION CRITERIA:Inclusion criteria:(a)published peer-reviewed articles on spinal cord injury-induced neurogenic bladder indexed in the Web of Science;(b)type of articles:original research articles and reviews;(c)year of publication:no limitation.Exclusion criteria:(a)articles that required manual searching or telephone access;(b)Corrected papers and book chapters. MAIN OUTCOME MEASURES:(1)Annual publication output;(2)distribution according to journals; (3)distribution according to subject areas;(4)distribution according to country;(5)distribution according to institution;and(6)top cited publications. RESULTS:There were 646 research articles addressing spinal cord injury-induced neurogenic bladder in the Web of Science.Research on spinal cord injury-induced neurogenic bladder was found in the Science Citation Index-Expanded as of 1946.The United States,Ireland and Switzerland were the three major countries contributing to studies in spinal cord injury-induced neurogenic bladder in the 1970s.However,in the 1990s,the United States,the United Kingdom,the Netherlands,Germany and Japan published more papers on spinal cord injury-induced neurogenic bladder than Switzerland,and Ireland fell off the top ten countries list.In this century,the United States ranks first in spinal cord injury-induced neurogenic bladder studies,followed by France,the United Kingdom,Germany,Switzerland and Japan.Subject categories including urology, nephrology and clinical neurology,as well as rehabilitation,are represented in spinal cord injury-induced neurogenic bladder studies. CONCLUSION:From our analysis of the literature and research trends,we conclude that spinal cord injury-induced neurogenic bladder is a hot topic that will continue to generate considerable research interest in the future.展开更多

The short-term effective rate in the acupuncture and moxibustion group was 90.6% and the long-term effective rate, 80.4%; whereas the short-term effective rate of the control group was 26.9% (P 0.05). Sixty-nine cases from the acupuncture and moxibustion group and 39 from the control group were subjected before and after treatment to determinations of the maximal bladder pressure, maximal abdominal pressure, bladder-neck pressure, and maximal urethral closure pressure during urination. All these indexes were decreased remarkably in the acupuncture and moxibustion group, while no changes were observed in the control group.展开更多
