??Abstracts?? Objective To investigate the changes of ventricular late potentials ??VLP?? in children with vasovagal syncope of vasodepressor response ??VVS-V??. Methods Totally 184 children ??aged from 4 to 14 years old??the average age being ??10.54±2.15?? years old?? had been diagnosed with VVS-V by head-up tilt table test ??HUTT?? ??study group?? from July 2006 to January 2013 in the Second Xiangya Hospital of Central South University?? male 85 cases?? the average age of ??10.85±2.01?? years old?? female 99 cases?? mean age ??10.27±2.24?? years old. Totally 105 healthy children were matched as controls. All subjects underwent VLP examination. Investigate the difference in HR?? TQRS?? LAS40 and RMS40 between the study group and the control group. Results Compared with the control group?? in the study group heart rate ??HR?? decreased ???83.96±12.27?? beats/min vs??87.28±13.75?? beats/min?? t = -2.113?? P??0.05???the total QRS time??TQRS?? ???84.89±12.05?? ms vs ??81.21±8.23?? ms?? t = 3.070?? P??0.05?? and high frequency and low amplitude limit??LAS40?? ???62.43±19.17?? ms vs ??56.79±1.83?? ms?? t = 2.442?? P??0.05?? were prolonged??and the root mean square plant??RMS40?? increased ???28.73±7.23?? μV vs ??26.89±7.36?? μV?? t = 2.059?? P??0.05??. Conclusions Compared to healthy controls??in VVS-V children HR reduces??TQRS and LAS40 prolong??and RMS40 increases. It suggests that VVS-V childrenare more likely to have cardiovascular incidents. 相似文献

Asthma and rhinitis epidemiology has wide variations around the world. The aim of this review was verify the prevalence of asthma and rhinitis in South America and report differences from other regions of the world. We reviewed studies with International Study of Asthma and Allergies in Childhood (ISAAC) methodology in South America, Phases I and III. In South America the ISAAC Phase I ranked four countries among top ten in prevalence of asthma and three countries among top ten in prevalence of rhinoconjunctivitis. ISAAC Phase III showed little changes in asthma and rhinitis prevalence in South American countries. The prevalence increases of asthma and rhinitis in South American centers indicate that the burden of both is continuing to rise, but the differences in prevalence are lessening. 相似文献

We report the case of a young girl who presented with acute severe pain from a genital ulceration. The diagnosis of ulcus vulvae acutum or Lipschütz??s acute ulcer of the vulva, a self-healing, acute genital ulceration of unknown origin but characteristic clinical picture was established. The patient recovered fully with symptomatic treatment, mainly appropriate analgetics within 14 days. A review of the scarce literature is discussed and the importance of non-invasive diagnostic procedures is stressed. 相似文献

Less than 10% of pancreatic ductal adenocarcinomas are based on a hereditary syndrome. In contrast a positive family history for pancreatic cancer raises the individual risk for the development of pancreatic and extrapancreatic malignancies. While 70% of hereditary pancreatic carcinomas can be attributed to the familiar pancreatic cancer syndrome 30% are caused by other hereditary syndromes, e.g., Peutz-Jeghers syndrome or familial adenomatous polyposis. Furthermore, genetically determined pancreatitis (e.g., hereditary pancreatitis or cystic fibrosis) can lead to pancreatic cancer. Up to now conclusive data for routine screening of high risk patients are not available which is due in part to the difficult identification of high risk patients and the problematic classification of detected pancreatic lesions. Therefore, high risk patients should be included in controlled clinical trials for screening. Small pancreatic lesions are not clear indications for surgical resection as false positive results can hamper a clear diagnosis and prophylactic pancreatectomy is not recommended. In the case of a histologically proven carcinoma a prophylactic extension of resection might be reasonable. Prevention of familial pancreatic cancer can be achieved through nicotine abstinence. 相似文献

Background
Patients with nonspecific abdominal pain (NSAP) are frequently seen in emergency departments. Different studies have suggested that early laparoscopy (EL) could be an adequate tool to accelerate diagnosis and therapy. The aim of this study was to assess the effectiveness of EL in terms of diagnosis, persistence of NSAP, mortality, morbidity, cost, hospital stay, and quality of life relative to observation in NSAP. 相似文献67.

Background
Knowledge of the position and shape of the endoscope could overcome many challenges of performing colonoscopy, e.g., loop formation. A novel computer-assisted colonoscope (NeoGuide Endoscopy System) delivers a real-time, three-dimensional map of the tip position and insertion tube shape in addition to the video image of the colon lumen. The aim of this study is to evaluate the mapping capabilities of the NeoGuide Endoscopy System in terms of colonic looping, insertion depth, tip position, and tip angle formation. 相似文献68.

Many types of local flaps are commonly used for the repair of circular skin defects. In this paper, we described that the
“North Star” design is useful for aesthetic removal of benign skin lesions. 相似文献

Summary
We have analysed the association of single-nucleotide polymorphisms (SNPs) in CD40 and CD40L genes with bone mineral density (BMD) in our women. Results showed that women with TT genotype for rs1883832 (CD40) and for rs1126535 (CD40L) SNPs displayed reduced BMD and increased risk for osteopenia/osteoporosis. Our data notwithstanding, the results need to be replicated. 相似文献70.
