TEN YEARS' EXPERIENCE IN LOW VISION PRACTICE

The Low Vision Clinic at the Palmerston North Hospital has now been oerating for 70 years. Over the course of these ten years a number of factors have emerged which can be as readily applied to general ophthalmological practice as to low vision practice. The philosophy of low vision care is one of which all ophthalmologists should be aware and includes factors to be taken into account when dealing with children, people in the workplace, and everyday factors involved in daily living activities, all of which are equally relevant in routine ophthalmological practice. This paper endeavours to share some thoughts on these factors and also discusses means by which the visually handicapped can be helped in areas where specialist low vision services are not readily available.     

Pycnogenol® as an Adjunct in the Management of Childhood Asthma

A randomized, placebo-controlled, double-blind study involving 60 subjects, aged 6-18 years old, was conducted over a period of 3 months to determine the effect of Pycnogenol® (a proprietary mixture of water-soluble bioflavonoids extracted from French maritime pine) on mild-to-moderate asthma. After baseline evaluation, subjects were randomized into two groups to receive either Pycnogenol® or placebo. Subjects were instructed to record their peak expiratory flow with an Assess® Peak Flow Meter each evening. At the same time, symptoms, daily use of rescue inhalers (albuterol), and any changes in oral medications were also recorded. Urine samples were obtained from the subjects at the end of the run-in period, and at 1-, 2-, and 3-month visits. Urinary leukotriene C₄/D₄/E₄ was measured by an enzyme immunoassay. Compared with subjects taking placebo, the group who took Pycnogenol® had significantly more improvement in pulmonary functions and asthma symptoms. The Pycnogenol® group was able to reduce or discontinue their use of rescue inhalers more often than the placebo group. There was also a significant reduction of urinary leukotrienes in the Pycnogenol® group. The results of this study demonstrate the efficacy of Pycnogenol® as an adjunct in the management of mild-to-moderate childhood asthma.     

"五四"新文学的内倾化形态

这种形态的文学其最为显著的标志是内倾化即自剖，暴露作家的思想观念，心灵情绪直到作家的私生活，包括作家的性心理与性行为等在一般社会眼中视为卑微的东西。作家们弘扬个人的心灵欲望，宣泄“食与色”的双重焦虑与痛苦，其思想内涵无疑带有强烈的反封建色彩。其批判的向度指向内外两个方面，既有对自我心灵严酷的审视，又有对于社会与国家的无情拷问。

影响儿童语言和识字能力的研究进展

现代生活中 ,儿童的语言和识字受家庭认知环境的影响。近年来无论从流行病学的研究 ,还是干预或神经生物的研究 ,均证实儿童早期经验是日后语言和识字能力发展的基础。在早期经验中 ,最关键的是父母与孩子之间的语言交流。通过这样的交流 ,促进儿童早期的语言发育 ,也促进儿童学龄期的阅读理解。儿童保健医生处于独特的位置 ,即在常规保健中指导父母根据不同年龄儿童的发育水平 ,应用有关的技能技巧 ,促进儿童的语言和识字。     

Contact dermatitis in patients with leg ulcers

100 patients with leg ulcers were patch tested against a standard battery of allergens. The readings were carried out daily from the 2nd to the 7th days. 55 patients showed positive reactions to one or more allergens. 32% of positive reactions developed for the first time after 48 h and 11% after 72 h. No single day or combination of two days gave 100% positive results. A single reading on the 4th day gave the highest number of positive reactions at 92%. The prevalence of positive patch tests was significantly higher in patients with surrounding eczema, and in patients with positive patch tests the ulcer duration was significantly longer than in those with negative patch tests. The total number of positive results in individuals increased linearly with the duration of the ulcer. Of allergens to which the ulcer was exposed, the occurrence of multiple sensitivity was significantly greater than predicted from the prevalence of individual sensitivities. However, there was no association between medicaments and metal sensitivity. This, together with the absence of an exponential rise in the number of allergens with the duration of ulcer, does not support the theory of systemic ampliative allergy.     

Literacy for early childhood: Learning from the learners

The originator of LETTERLAND describes a unique teaching model which blends a structured phonics approach with whole language teaching. Children are introduced to a language about language which enables them to acquire a confident mastery of print based on parallel learning. Its pictogrammatic approach creates a stimulus to inquiry and a learning environment which is imaginative and friendly.     

Regional cerebral activity associated with the incidental processing of pseudo-words

In order to study brain activity associated with “incidental” cognitive processing, regional cerebral blood flow (rCBF) was measured in six volunteers while they monitored a sequence of pseudo-words (e.g., FLOPE) for the rare occasions when the letters were displayed in blue rather than white. In the control condition, the same pseudo-word was presented repeatedly. In one experimental condition all 60 pseudo-words were different, while in the other there were 18 repetitions. Although it was not necessary to “read” the pseudo-words to perform the monitoring task, subsequent forced choice recognition memory for these stimuli was significantly greater than chance. Furthermore, there were significant differences in blood flow between the three conditions. When different pseudo-words were presented there was significantly greater activity in brain areas concerned with shape and object identity (extrastriate cortex bilaterally), with visual word form (left inferior temporal gyrus), and with articulatory word form (Broca's area) even though none of this information about the pseudo-words was needed for performance of the monitoring task. In the condition in which some of the words were repeated, there was significantly reduced activity in the right lingual gyrus. This area may therefore be a possible anatomical locus for repetition priming with verbal stimuli. These results indicate the importance of taking into account incidental processing when designing tasks for functional imaging experiments. © 1995 Wiley-Liss, Inc.
