Latex allergy and latex sensitization in children and adolescents with meningomyelocele.

BACKGROUND: The high prevalence of clinical latex allergy and latex sensitization in children with meningomyelocele has been widely reported. It has also been noted that these same children have a higher than expected prevalence of atopic disease. It would be useful to have a safe, sensitive, and specific skin test to detect latex sensitivity and to know how well this test compares with available in vitro tests. It would likewise be helpful to know as fully as possible the characteristics of the individual and to evaluate the relative importance of factors suspected to contribute to clinical latex allergy and latex sensitization in this population. METHODS: A group of 116 children and adolescents 1 to 20 years of age were recruited for the study. An extensive history of latex allergy, atopic diseases, and surgical procedures was taken on all subjects. Each subject had either a latex skin test or an in vitro study for latex-specific IgE, and 67 subjects had both tests simultaneously. Eighty-five subjects had epicutaneous skin tests to a panel of environmental allergens. RESULTS: Overall, 25 of 116 (21.5%) subjects had a history of clinical latex allergy, and 51 of 116 (44%) were sensitized to latex. The sensitivity and specificity of skin tests for clinical latex allergy were slightly greater than for the in vitro test (100% vs 95.8% and 82.3% vs 68.9%, respectively). The positive predictive value and negative predictive value of skin testing for clinical latex allergy were also greater (67.6% vs 50% and 100% vs 98.1%, respectively). Age was found to be a significant variable for both latex allergy and latex sensitization. The number of surgical procedures undergone and the presence of positive skin test responses to environmental allergens were significantly correlated with latex sensitization but not with clinical allergy to latex. CONCLUSIONS: A sensitive, specific, and safe skin test for latex sensitivity appears superior to in vitro testing for latex allergy. Age, number of surgical procedures, and the presence of positive allergen skin test responses are significantly correlated with latex sensitization. Age alone is significantly correlated with clinical allergy to latex.

Town population change in the Republic of Ireland: the need for an urban policy review.

"This article argues for the adoption of a co-ordinated urban planning policy in the Republic of Ireland where towns now accommodate 64% of the total population. A review of trends in town population change for the years 1986-91 suggests that the ad hoc approach to planning urban employment and service provision that exists currently is inadequate to prevent major disparities in population distribution becoming exacerbated between large and small settlements and between regions within the state. These disparities are the result in part of fundamental economic restructuring which is related to international trends but they also reflect the gradual withdrawal by the Irish Government from regional planning from the mid-1980s on. By way of introduction to the discussion of the empirical evidence, an earlier phase of Irish urban and employment planning is reviewed briefly."

Childhood growth, physical activity, and peak bone mass in women.

Peak bone mass is an important determinant of the risk of osteoporotic fracture, and preventive strategies against osteoporosis require a clear understanding of the factors influencing bone gain in early life. We report a longitudinal study aiming to identify the relationships between childhood growth, lifestyle, and peak bone mass in women. One hundred and fifty-three women born in a British city during 1968-1969 were traced and studied in 1990. Data on their growth in childhood was obtained from linked birth and school health records; current bone mineral measurements were made by dual X-ray absorptiometry. There were statistically significant associations between weight at 1 year and BMC (but not BMD) at the lumbar spine (r = 0.32, p < 0.01) and femoral neck (r = 0.26, p < 0.01). These remained significant after adjusting for current weight. There were also strong relationships between childhood height measurements and adult BMC at the two skeletal sites. Physical activity was the major lifestyle determinant of BMD after allowing for body build. We conclude that infant growth and physical activity in childhood are important determinants of peak bone mass in women. Growth primarily determines the size of the skeletal envelope, and its trajectory is established by age 1 year. Activity, in contrast, modulates the mineral density within the skeletal envelope and may contribute to the consolidation of bone following the end of linear growth.

Population change in the Republic of Ireland 1981-1991: trends and spatial patterns.

"Demographic trends in the Republic of Ireland have gradually moved closer to Western European norms during the past two decades. Birth rates have continued to fall and internal migration flows have become diversified. External migration has continued to play an important role in population change, however, and in the most recent census period has contributed to net decline. Geographical patterns of change within the state reflect a concentration of growth in the environs of the larger centres of population." (SUMMARY IN FRE)

Informational and psychosocial needs of women choosing conservative surgery/primary radiation for early stage breast cancer.

Recent advances in the treatment of early stage breast cancer give women a choice of treatments. Prospective and retrospective studies demonstrate the comparable efficacy of treatment with a modified radical mastectomy and treatment with conservative surgery and primary radiation. While the number of women with early stage breast cancer choosing the latter treatment continues to increase, there is a paucity of information in the nursing literature assessing the informational and psychosocial needs of this group. This article reports the results of a questionnaire assessing the informational and psychosocial needs of patients choosing breast conservation surgery, and the future implications of these results for the nursing profession.

Disease expression of ankylosing spondylitis in males and females.

The clinical features of 35 female patients with ankylosing spondylitis were compared with 70 male controls individually matched for disease duration. Mean age of onset and presenting symptoms were similar in both groups. No differences were observed as regards spinal symptoms, chest expansion, peripheral arthritis, extraarticular features or functional outcome. However, males had significantly greater spinal radiological change that was positively associated with hip arthritis. Our findings suggest that although axial disease is more severe in males the overall pattern of clinical disease is similar in both sexes.

Real-time movie imaging from a single cardiac cycle by NMR.

Using a 1-m-bore superconductive magnet at 0.1 T, whole-body transverse images through adult humans have been obtained at repetition times of 57 ms. The techniques used were minor variations of echo-planar imaging (EPI) employing large pulsed gradients to provide complete coverage of the plane in phase space, and low-angle RF excitation sequences allowing rapid repetition of the experiment. In addition active magnetic screening of the gradient coils was implemented to protect the surrounding magnet from the eddy currents induced by the necessarily fast switching of the large gradient fields.

Echo planar imaging of normal and abnormal connections of the heart and great arteries.

Echo planar imaging (EPI) is that form of magnetic resonance imaging which provides very short image acquisition times. EPI also provides very rapid sequential imaging. The EPI method is ideal for imaging the heart and thoracic content because images are devoid of cardio-respiratory motion artefact. Previously an analysis of transectional images has been presented. This paper is concerned with the study of the heart by the use of EPI constructions in the sagittal and coronal planes. Defining connections between ventricle and great artery is of cardinal importance in paediatric cardiology. EPI constructions in the normal heart, transposition, truncus arteriosus and right heart hypoplasia are presented and discussed.

Transectional echo planar imaging of the heart in cyanotic congenital heart disease.

Echo planar imaging is that form of magnetic resonance imaging which gives very short image acquisition times. The method has been used to produce images of the infant heart which are free of cardiorespiratory motion artefact, despite tachypnoea and tachycardia. EPI transections of the normal heart are compared with transections in truncus arteriosus, tetralogy of Fallot, right heart hypoplasia and transposition of the great arteries. The diagnosis of the cause of cyanosis in these infants was established by the noninvasive EPI method and validation of the findings may be found in transectional postmortem analyses reported in the literature.

Attention-deficit hyperactivity disorder and fluctuating asymmetry in another college sample.

Attention deficit/hyperactivity disorder (AD/HD) represents a developmental lag that may be reflected in fluctuating asymmetry (FA), i.e., differences from perfect symmetry in traits that display bilateral symmetry. Burton et al. (2003 Am. J. Hum. Biol. 15:601-619) found a statistical trend for FA to increase (as dermatoglyphic index or as total index) as the behavioral measure for AD/HDness (Rasch logit values derived from the Wender Utah Rating Scale, or WURS) increased in males but not in females. The objective here was to do a similar study in an independently collected sample of college students (n = 222; 61 male, 161 female) not selected for AD/HD, looking at FA vs. symptoms for AD/HD based on Rasch versions of responses to the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) (Barkley and Murphy 1998 Attention-Deficit Hyperactivity Disorder, New York: Guilford Press, p. 95-96) and the more comparable shortened WURS. FAs were lowest for body and ear height, and highest for eye width and nose width, and ranged from 0.01 +/- 0.001 (mean +/- SE) for foot and ankle widths to 0.13 +/- 0.01 in eye and nose widths for both sexes; the sexes did not differ significantly. Males displayed higher AD/HD symptom rates overall. There was a significant correlation between body FA and the WURS measure in females after Bonferroni correction (P = 0.002, r(2) = 0.058). Thus, AD/HD symptoms levels increased with an increase in body FA in female college students not selected for AD/HD.
