Bone density profiles and osteoporosis incidence in Irish females.

1725 Irish females aged 15-70+ were included in this analysis to establish the group bone mineral density (BMD) profiles. Each subject was screened for 27 risk factors by questionnaire. Subjects were segregated into normal (N) and non-normal (NN) subgroups on the basis of the questionnaire. BMD of lumbar spine and hip were measured by dual energy X ray absorptiometry (DEXA). A substantial difference in BMD at all sites was observed between subgroups even following adjustment for body mass index and years of exposure to oestrogen. In the subgroup designated as non-normal 42%, 54%, 72% and 69% of those studied had spinal BMD levels > 2SD below mean peak at 55-59, 60-64, 65-69 and 70+ respectively. In comparison, similar age cohorts in the subgroup designated normal were 26%, 46%, 44% and 68% respectively. A marked difference was also observed in the younger age groups (15-34) where the percentage of individuals with spinal BMD levels > 2SD below mean peak was < 1.9% for N and 18.8% for NN. The results of this study suggest that the use of a questionnaire may be a valuable low cost screening tool in the younger groups.

Improving drop administration by patients.

1. Patients that have difficulties with drop application may have poor compliance with therapy. We studied the effectiveness of teaching a technique of drop administration that allows the patient to steady the hand and observe the dropper tip during application. 2. Comparing the group taught the technique of application with another group who had their drops applied by a home caregiver, we found that those taught the technique were as reliable as the others in the delivery of their drops. 3. Although some patients will be physically incapable of applying drops, we found that the technique we describe in the present study enables effective and safe delivery of drops.

The Dublin outcome for low birth-weight infants.

This report describes outcomes for all infants with birth weight 501-1750 grams born in the three major maternity hospitals in Dublin between 1.1.90 to 31.12.91. 37,958 mothers delivered 38,498 infants during this period, consisting of approximately 36% of all deliveries in Ireland. 633 (1.6%) of all infants born weighed 501-1750 grms. 102 (16%) were stillborn and 28 of the 531 live born infants had lethal malformations. 30% of women received two or more doses of antenatal steroids before delivery and a highly significant negative correlation occurred between the need for ventilation after birth and antenatal steroids. 56.4% of babies were delivered by caesarean section as compared with 10.8% of the hospital population. Of 503 liveborn infants without lethal malformation. 426 (85%) survived to 28 days and 419 (83%) to discharge home. 15% were growth retarded. 46% of infants were ventilated, mean duration of ventilation was 7 days. 25% of infants had an intraventricular haemorrhage, 10% necrotising enterocolitis and 19% culture proven sepsis. 15% of survivors developed broncho pulmonary dysplasia and 12% retinopathy of prematurity. This paper describes important information for mortality, morbidity and interventions among a large population of low birth weight infants in Ireland and can be used as a basis against which to compare future alterations in practice. It demonstrates a clear benefit for antenatal steroids in decreasing the need for ventilation and the importance of ensuring their utilisation antenatally where possible.

Postoperative delirium in the elderly.

Older patients are at a higher risk for postoperative delirium. Symptoms of delirium are flucuating sensorium, altered perception and attention levels, and increased confusion. The incidence of delirium after surgery does not correlate with a specific anesthetic agent or the route of administration.
