Hospital Episode Statistics and trends in ophthalmic surgery 1998 – 2004

Background  

Hospital episode statistics (HES) is a UK national database for the National Health Service (NHS), now available online. The purpose of this study was to observe trends in ophthalmic operations performed during the period from 1998 to 2004, using this data.     

产后失血性休克诊断及处置的四字方针

按照发生的时间不同,产科出血可分为产前出血和产后出血.产前出血的主要原因有前置胎盘和胎盘早剥,产后出血的发生率和严重程度要显著高于产前出血,本文将着重探讨产后失血性休克的诊断和处置.     

Long-term surgical results for congenital aural atresia

Thirty-nine primary surgical cases for correction of congenital aural atresia were reviewed for complications and long-term hearing results. Hearing averages of 25 dB for mild atresia, 40 dB for moderate atresia, and 46 dB for severe atresia were obtained. Serviceable hearing was achieved in 64% of the cases. The two most frequent complications were stenosis and recurrent infections of the cavity and canal skin, with an incidence of 33% and 31%, respectively. Use of split-thickness instead of full-thickness skin graft was associated with fewer complications. The goal of this review is also to share the experience of the senior author in the management of this complex problem.

青年人群血清流感抗体水平纵向监测

通过对北京４０５例青年１９９２～１９９４年流感抗体的纵向监测结果表明，３年中Ｂ型流感表现很活跃，抗体分别在１９９３年和１９９４年春出现高峰。Ａ型流感抗体在１９９３年春出现高峰。其中２１８例个体连续３年６次抗体检测，据抗体波动提示：３年中流感３个亚型总的感染频率为４４０％，每个体每年平均为１．４次，其中Ａ１型感染频率最高，每个体３年内平均１．８次；Ａ３型次之为１．５２；Ｂ型为１．０６。流感３个亚型抗体在机体内有６７％～７３％高水平抗体个体可在０．５～１年内下降至≤２０的低水平。２１８例个体中Ａ１型抗体３年内长期低水平者有３％，Ａ３有９％，Ｂ有３８％。     

Attentional demands of continuously monitoring orientation using vestibular information.

The aim of this series of experiments was to determine whether attention is normally required for continuously processing vestibular information concerning orientation, or is required only when orientation is disrupted (eg by vestibular dysfunction or by conflicting visual and vestibular orientation cues). In the first two studies, healthy subjects were passively oscillated, and indicated when they perceived they were passing through their starting position. There was only weak evidence for interference between performance on this 'continuous orientation monitoring task' and on concurrent mental tasks. However, a third study showed that when patients with vestibular imbalance carried out the continuous orientation monitoring task their performance on a concurrent mental arithmetic task was substantially impaired. This dual task interference was correlated with inaccuracy in judging orientation on the continuous orientation monitoring task, which in turn correlated with severity of recent vestibular symptomatology (assessed by questionnaire). In a fourth experiment, disorientation was induced in healthy subjects by rotating the visual field about the line of sight. Bidirectional interference was observed between monitoring orientation (assessed by accuracy in setting a rod to the perceived vertical) and performance of an arithmetic task. Dual task interference was correlated with baseline levels of disorientation induced by the visual field, as indicated by inaccuracy in judging the visual vertical. These findings suggest that monitoring orientation makes significant demands upon cortical processing resources when disorientation is induced, whether the disorientation results from deficient sensory functioning or from ambiguous perceptual information.
