Poor recognition of the UK minimum driving vision standard by motorists attending optometric practice

OPHTHALMIC AND PHYSIOLOGICAL OPTICS, Issue 3 2007
Jonathan S. Pointer
Abstract Purpose:, To evaluate the current level of recollection of the vehicle number plate viewing distance in a group of motorists. Knowledge of this distance is required to self-check compliance with the UK legal minimum driving vision standard. Methods:, A cohort of 480 motorists aged ,17 years attending optometric practice for a routine sight test agreed to participate in a short verbal survey. They were asked whether they could state the current UK statutory vehicle number plate viewing distance as specified in the Highway Code. Also recorded were each motorist's high contrast logMAR visual acuity, whether or not an optical prescription was habitually worn when driving, and brief demographic details (age, gender). Results:, No statistically significant gender-based difference was present in age distribution, mean logMAR binocular acuity, or age and number (proportion) of motorists who habitually wore a refractive correction when driving. The level of mean binocular acuity was uniformly good (<0.0 logMAR, or better than 6/6 Snellen). However, the recollection by respondents of the statutory viewing distance was poor: only 5% were able to state correctly the current distance (20 m), and 22% recalled the previous (20.5 m/67 ft) or the original (22.9 m/75 ft) statutory distance. Of the remainder, 28% underestimated and 45% overestimated the distance. A statistically significant gender-based difference (p = 0.01) between the recollections of non-prescription wearers became marked (p = 0.001) for habitual wearers, in which latter case the median value and range of estimates by female motorists was greater than their male counterparts. Conclusions:, The level of recognition by these motorists of the viewing distance necessary to satisfy the legal minimum vision standard required for driving on UK roads was low and comparable to the levels recorded in two similar surveys undertaken by other authors 10 and 20 years ago. An inexpensive and easily implemented publicity innovation is suggested which could help improve driver appreciation of the statutory distance and promote compliance with the legal vision standard.

Lumbosacral osteochondrosis: radiological features and surgical management in 34 dogs

JOURNAL OF SMALL ANIMAL PRACTICE, Issue 6 2001
F. Y. Hanna
Lumbosacral osteochondrosis has been diagnosed with increasing frequency over the past few years. Nevertheless, poor recognition of the condition continues to lead to frequent misdiagnosis. A study was therefore undertaken over a 12-year period (1986 to 1998) to describe the use of a variety of radiological studies to define the syndrome and the use of different surgical techniques for optimal treatment of the condition. Dogs with clinical signs of cauda equina neuropathy and radiological signs of lumbosacral osteochondrosis were older than 14 months (mean age 6-3 years). German shepherd dogs, boxers and rottweilers were heavily represented. Of the 34 dogs with osteochondrosis in this study, the lesion appeared to be related to the sacrum in 31 dogs (91 per cent) and the seventh lumbar vertebra in the remaining three dogs (9 per cent). Twenty-seven male and seven female dogs were affected (4:1). Out of the 34 dogs, six (18 per cent) were treated conservatively and the remaining 28 (82 per cent) were treated surgically. The outcome of surgical treatment was considered to be satisfactory in 24 (86 per cent) of these latter dogs. [source]

Therapeutic intent of proton pump inhibitor prescription among elderly nonsteroidal anti-inflammatory drug users

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2009
A. M. DRIES
Summary Background, Prescription of proton pump inhibitors (PPIs) has increased dramatically. Aim, To assess therapeutic intent of PPI prescription among elderly veterans prescribed nonsteroidal anti-inflammatory drugs. Methods, Medical-record abstraction identified therapeutic intent of PPI prescription. An ,appropriate therapeutic intent' was defined as symptomatic gastro-oesophageal reflux disease or endoscopic oesophagitis, Zollinger,Ellison disease, dyspepsia, upper gastrointestinal event, Helicobacter pylori infection or nonsteroidal anti-inflammatory drug gastroprotection. Logistic regression predicted the outcome while adjusting for clinical characteristics. Results, Of 1491 patients [mean 73 years (s.d. 5.6), 73% white and 99.8% men], among those charts which did document a therapeutic indication, 88.8% were appropriate. Prior gastroscopy was predictive of an appropriate therapeutic intent (OR 2.7; 95% CI: 1.9,3.7). Prescription to patients who used VA pharmacy services only, to in-patients, or by a cardiologist or an otolaryngologist were less likely to be appropriate. Gastroprotection was poorly recognized as an indication for PPI prescription, except by rheumatologists (OR 46.7; 95% CI: 15.9,136.9), or among highly co-morbid patients (OR 1.8; 95% CI: 1.1,2.9). Among in-patients, 45% of PPI prescriptions were initiated for unknown or inappropriate reasons. Conclusions, Type of provider predicts appropriate PPI use. In-patient prescription is associated with poor recognition of necessary gastroprotection and unknown therapeutic intent. [source]

Human T and B cell epitope mapping of Taenia solium paramyosin

PARASITE IMMUNOLOGY, Issue 11 2001
José Vázquez-Talavera
Taenia solium paramyosin is an immunodominant antigen in human and porcine cysticercosis that has shown promise as a vaccine candidate against schistosomiasis and some filariasis. There are few studies to identify the immunologically relevant regions of paramyosin. In this work, we characterize the humoral and cellular response of neurocysticercotic patients against T. solium paramyosin. Western blots using different recombinant fragments of T. solium paramyosin, showed that the sera from neurocysticercotic patients were strongly reactive against the carboxyl end region, with poor recognition of the central and amino regions. In contrast, the cellular immune response of patients did not show preferential recognition of any region of paramyosin. [source]
