Abstract
To test our hypothesis that the onset of the menopause would be associated with an increased number of underfoot accidents in the female population for both fracture and non-fracture injuries, we analysed 90061 accidents recorded by the Home Accident Surveillance System and classified them as to (a) whether a fracture resulted, and (b) whether they were 'underfoot'. We defined 'underfoot' accidents to have an event such as a trip, slip, missed footing, twisted or turned ankle, on the level or on stairs. All other accidents, including falls from or off structures, or falls caused by medical conditions were classified as 'not underfoot'. Overall, 51.3% of women and 32% of men were injured in underfoot accidents. There was an increase with age in the percentage of fractures in both men and women, mainly due to an increased risk of fracture in underfoot accidents: underfoot accidents caused 75.9% of all fractures in women and 55.4% in men. The number of women who had fractures following underfoot accidents increased sharply after the age of 50 years, and the number continued to rise up to 80 years. The number of non-fracture injuries in elderly women from underfoot accidents also increased with age. Osteoporosis on its own does not explain our result, and changes in muscle strength and reaction time, with age in both men and women, and at a greater rate in postmenopausal women, may be an important factor in underfoot accidents.

Abstract
Cystic fibrosis (CF) is associated with significant morbidity and mortality, despite significant advances in conventional treatment. The field of gene therapy has progressed rapidly since the cystic fibrosis transmembrane conductance regulator (CFTR) gene was cloned. In this review we discuss current knowledge on the underlying molecular defect in CF, and the progress in gene transfer studies from the early in vitro work through to clinical trials, including the development of endpoints to assess efficacy. We highlight the problems encountered, and likely future directions of the field.

Abstract
OBJECTIVES To compare and contrast the prevalence of pneumoconiosis in two groups of former migrant mineworkers in southern Africa, and to examine the effectiveness of the South African compensation system for occupational lung diseases. DESIGN Comparison of two cross-sectional studies and follow-up data on compensation results. SETTING The village of Thamaga, Botswana and the rural area of Libode, Eastern Cape, South Africa. SUBJECTS Two hundred and thirty-four former underground mineworkers in Thamaga, and 238 in Libode. MAIN OUTCOME MEASURES Prevalence and severity of pneumoconiosis, prevalence of radiological signs of tuberculosis (TB), Medical Bureau for Occupational Diseases (MBOD) certification committee decisions, and compensation results. RESULTS Prevalence of pneumoconiosis > or = 2/1 was 15.4% in Libode and 13.6% in Thamaga. Significantly more Libode than Thamaga subjects (51.1% versus 29.0%) reported past TB treatment. Radiological signs of pulmonary TB were also more prevalent in Libode (33.3% v. 23.9%). Twenty-six per cent of Libode men and 16.1% of Thamaga men were certified with compensable disease. Libode payments were finalized within 30 months, whereas Thamaga cases only began receiving payments 52 months after medical examination, with 11 cases still pending 66 months after medical examination. CONCLUSION There was a high prevalence of pneumoconiosis in both study groups. Many men were eligible for compensation but were previously uncompensated. The higher rate of compensable disease in the Libode group may relate to the higher prevalence of TB, as well as more active follow-up by the study group, including a large number of appeals. Socio-political changes in South Africa between 1994 and 1996 may also have influenced compensation results.

Abstract
The past decade has brought significant advances in the field of gene therapy for both inherited and acquired diseases, especially with regard to respiratory disease. Barriers to gene transfer posed by the lung have led to the development of modifications of both vector and host in an attempt to increase the efficiency of transfer. Recently, progress has been made in both laboratory and clinical studies of gene therapy for cystic fibrosis, alpha1-antitrypsin deficiency and lung cancer.

Abstract
Underfoot accidents taken from a study of patient interviews have been analysed to investigate factors that may be implicated in the causes of the accidents. Within the sample of patients in this study women holding items are more at risk than men from underfoot accidents. Carrying items such as shopping and handbags may obstruct the line of sight to underfoot hazards, affect balance and adversely affect reflex corporal movements that may help prevent injury.

Abstract
It is unclear whether inflammation in the cystic fibrosis (CF) lung relates predominantly to bacterial infection, or occurs as a direct consequence of mutant cystic fibrosis transmembrane conductance regulator (CFTR) protein. Interleukin (IL)-8 secretion from CF and non-CF cell lines, and from CF and non-CF human primary nasal epithelial cells incubated with or without Pseudomonas aeruginosa, was measured. Activation of nuclear factor-kappaB (NF-kappaB) in unstimulated CF and non-CF nasal epithelial cells, cell lines and murine tissues was measured by gel-shift assays. No significant difference in basal IL-8 production or NF-kappaB activation was observed between CF and non-CF primary nasal cells. However, CF cells exhibited a significantly (p<0.01) increased IL-8 secretion following P. aeruginosa stimulation. Equalization of the increased P. aeruginosa adherence observed in CF cells, to non-CF levels, resulted in comparable IL-8 secretion. Further, IL-8 production did not differ with mutations which result in either correctly localized CFTR, or in partial/total mislocalization of this protein. Similar levels of NF-kappaB activation were observed in a number of organs of wildtype and CF mice. Finally, IL-8 secretion and NF-kappaB activity were not consistently increased in CF cell lines. Cos-7 cell transfection with plasmids expressing deltaF508 or G551D mutant CFTR protein resulted in increased activation of a p50-containing NF-kappaB complex, but IL-8 secretion was similar to wild-type cells. The authors conclude that the stimulus produced by Pseudomonas aeruginosa is the predominant inflammatory trigger in their models.

Abstract
Despite advances in conventional treatments for cystic fibrosis (CF), the disease is still associated with significant morbidity and mortality. The cloning of the cystic fibrosis transmembrane conductance regulator (CFTR) gene and the understanding of the functions of the CFTR protein have led to the development of novel treatment strategies, including gene therapy. Here, we review the underlying molecular defect in CF cells, and the progress in gene-transfer studies from in vitro work through to clinical trials. We discuss the problems encountered, the end-points used to assess efficacy, and the likely future directions of the field.

Abstract
Much of the morbidity and mortality seen in cystic fibrosis (CF) is related to chronic infection of the respiratory tract with Pseudomonas aeruginosa. Some studies have attributed the strong relationship between CF and Pseudomonas colonization to the presence of increased numbers of specific cell-surface receptors, although other work suggests that this relates to the presence of mucus. Several groups are now assessing the use of gene transfer as a novel form of treatment for CF. We have examined whether P. aeruginosa binding to freshly obtained CF respiratory epithelial cells is increased, and have studied the effects of transfer of the CF transmembrane conductance regulator (CFTR) gene on this attachment. Binding of P. aeruginosa to noncultured nasal epithelial cells from both CF patients (n = 31) and healthy controls (n = 15) was studied with scanning electron microscopy. Binding was also assessed for CF cells following transfection with CFTR/liposome complexes. Epifluorescence microscopy was used to assess the effects of gene transfer on chloride fluxes. Adherence of P. aeruginosa directly to the cell surface of CF airway epithelium was significantly (P < 0.001) increased over that in non-CF controls. Liposome-mediated CFTR gene transfer resulted in a significant (P < 0.01) reduction in the numbers of bacteria bound to ciliated epithelial cells. Fluorescence microscopy confirmed correction of the basic chloride defect. Thus, in CF, the absence of normal CFTR results in increased binding of P. aeruginosa to respiratory epithelial cells. This abnormality can be corrected in vitro by restoration of CFTR function. This has important implications both for the pathogenesis of CF and for the future application and assessment of gene therapy for this disease.

Abstract
In this study, human insulin was compared with two of its analogs--LysB28ProB29-human insulin and AspB10LysB28ProB29-human insulin-with respect to bioavailability and metabolic effectiveness. Absorption from the subcutaneous site was determined using kinetic parameters from the washout curve, following intravenous infusion of insulin or analog. Absorption was found to be more rapid for the two analogs, with 90% absorption by 100 min for the analogs and by 180 min for insulin. Total absorption was 97 +/- 10% for insulin, 99 +/- 7% for LysB28ProB29-human insulin, and 93 +/- 12% for AspB10LysB28ProB29-human insulin. Bioactivity was assessed from the glucose infusion and using tracer-determined metabolic clearance rates (MCRs) and glucose production rates. The fractional glucose requirements (relative to the total amount infused) increased more rapidly for the two analogs than for insulin, with 50% of the glucose infused by 105 min for both analogs vs. 145 min for insulin. The total amount of glucose required was, however, significantly less (19.7 +/- 1.5 mmol/kg) for AspB10LysB28ProB29-human insulin than for either LysB28ProB29-human insulin (25.9 +/- 3.0 mmol/kg) or human insulin (27.8 +/- 2.6 mmol/kg). The glucose requirements were reflected in a lower MCR for AspB10LysB28ProB29-human insulin but equivalent decreases in the rates of glucose production. Thus both analogs demonstrated more rapid rates of absorption, onset, and termination of action, but were not completely bioequivalent, with AspB10LysB28ProB29-human insulin demonstrating a 25% decrease in bioactivity.

Abstract
Spastic quadriplegic cerebral palsy (SQCP) is a severe disability that is associated with abnormal physical activity, body composition, and food intake and with frequent malnutrition. This study examined the pattern of dietary intake, anthropometry, and energy expenditure in a group of subjects with SQCP aged 2-18 y and a normal control group. The energy expenditure pattern was determined from resting energy expenditure (REE, n = 61 SQCP; n = 37 control group) by using indirect calorimetry and from total energy expenditure (TEE, n = 32 SQCP; n = 32 control group) by using the doubly labeled water method. Physical activity, including the chronic spasticity of SQCP, was estimated from the ratio of TEE to REE. Abnormal growth and body composition were common and dietary intake was markedly overreported in the children with SQCP. Children with SQCP were divided according to body fat stores determined by triceps-skinfold-thickness measurements. The children with low fat stores had a lower REE adjusted for fat-free mass compared with the SQCP and control groups with adequate fat stores. TEE was significantly lower for the SQCP group than for the control group. The ratio of TEE to REE, indicating energy for nonbasal needs, was significantly lower in the SQCP children than in the control group, with the adequately nourished SQCP children having lower ratios than the more poorly nourished SQCP group. The nonbasal energy expenditure, such as for physical activity and spasticity, of children with SQCP was low. The nutrition-related growth failure and abnormal pattern of REE are likely related to inadequate energy intake.

Abstract
More than 2 million upper limb injuries occur each year in Britain. Information about the precise sequence of events leading up to an accident may help prevention of similar injuries by alteration of the work environment or through safety education. The first impression of the cause of an accident may not identify the key event triggering it. The Merseyside Accident Information Model (MAIM; Manning, 1987) provides a structured questionnaire, based on a menu-led computer programme. This not only allows the first unforeseen event to be identified from the history, but is also the basis of a database. Pooled data can then be analyzed. We present an analysis of 100 consecutive cases presenting to one Plastic Surgery Unit.

Abstract
The growth failure and nutritional status were assessed of 154 children with diplegic or hemiplegic cerebral palsy, aged between two and 17.4 years. Linear growth was significantly reduced compared with norms for healthy children. About 30 per cent of the sample were undernourished, indicated by bodyweight or depleted subcutaneous fat stores at the triceps skinfold site. 8 per cent were overly fat by triceps skinfold and 14 per cent overweight by bodyweight. 23 per cent of the children had stunted growth. Children in the youngest age-group were most at risk for poor nutritional status and delayed growth. These findings suggest that children with diplegic or hemiplegic cerebral palsy are at risk for a variety of abnormalities of growth and nutritional status, and that a growth and nutritional assessment should be conducted periodically so that under- or overnutrition can be corrected when identified.

Abstract
Growth failure and nutritional status were evaluated in 142 children with quadriplegic cerebral palsy, aged between two and 18 years. Linear growth was assessed by upper-arm and lower-leg lengths: both means were significantly reduced. Mean bodyweight and triceps skinfold thickness fat stores were reduced to 65 per cent medians and subcapsular skinfold fat stores to 81 per cent median. Muscle stores were the most preserved and reduced to 88 per cent median. Examination of the sample by age-group showed significant reductions in growth and nutrition status indicators, even at two to four years, except for muscle area. To determine the degree to which nutritional status affected linear growth, a set of two-step regression analyses was conducted. The linear growth measures were significantly correlated with the measures of nutritional status.

Abstract
The effects of exercise training on riboflavin requirements and of riboflavin intake on endurance were examined in 14 women, 50-67 y of age, who participated in a 10-wk, two-period crossover exercise study at two riboflavin intakes, 0.15 micrograms/kJ (0.6 micrograms/kcal) and 0.22 micrograms/kJ (0.9 micrograms/kcal). Subjects exercised 20-25 min/d, 6 d/wk, for 4-wk periods on a cycle ergometer at 75-85% of their maximal heart rate. Riboflavin status was assessed by measuring the erythrocyte glutathione reductase activity coefficient (EGRAC) and urinary riboflavin excretion. Physical performance was evaluated by using a walking treadmill test to determine maximal oxygen capacity (VO2max) and anaerobic threshold by gas exchange (ATGE). Exercise significantly affected riboflavin status as EGRAC increased (P less than 0.001) and riboflavin excretion decreased (P less than 0.01) in both groups. VO2max increased significantly with exercise (P less than 0.01). However, changes in VO2max (L/min) and ATGE with exercise training were not different in the two groups. Riboflavin requirements of older women increased with exercise training, but increased riboflavin intake did not enhance improvements in endurance.

Abstract
A study was undertaken to determine if there were detectable effects on the respiratory health status of children resident in the eastern Transvaal highveld as a consequence of their exposure to community air pollution, comparing them with children in areas ostensibly less polluted. A prevalence study was conducted in white schoolchildren from 11 schools in the eastern Transvaal highveld (1,031 children) and from 11 schools in non-polluted towns in the Transvaal (978 children). A questionnaire was completed by each child's mother, and height and weight were measured and spirometry recorded on a vitalograph. Cough, wheeze, asthma and chest illnesses were more frequently reported from polluted areas compared with non-polluted areas, taking into account parental smoking and home cooking fuel (odds ratios 1.34, 1.20, 1.15 and 1.88, respectively). After correcting for age, children in the polluted area were 0.83 cm shorter (P = 0.035). However, there were no significant differences in forced vital capacity and forced expiratory volume in 1 second after standardising for height, age, parental smoking and home cooking fuel. We conclude that, in children, exposure to pollution in the eastern Transvaal highveld may cause respiratory symptoms and chest illness and may affect height but does not measurably affect lung function, as assessed by spirometry.
