Data collected during a prospective cohort study of infant feeding and health in rural Bilbeis, Egypt, were analysed to define prelacteal infant feeding practices, identify their determinants, and assess whether these practices were predictive of breastfeeding and supplementation patterns and diarrhoea incidence during infancy. Sixty per cent (89/149) of study infants were prelacteally fed sugar-water, teas, or both. Lack of milk in the mother's breast (74 per cent), and maternal exhaustion or illness following labour (29 per cent) were the two most commonly stated reasons for prelacteal feeding. After multivariate adjustment, significantly higher incidence of prelacteal feeding was associated with childbirth during the warmer months [odds ratio (OR): 2.4; 95 per cent confidence interval (CI): 1.1-5.1], birth attendants with modern training (OR: 5.5; 95 per cent CI: 1.7-17.5), and labour lasting > 8 hours (OR: 2.3; 95 per cent CI: 0.1-4.9). Prelacteally fed infants were significantly less likely to be exclusively breastfed in age periods 0-3, 4-7, and 8-11 weeks. Diarrhoea incidence was higher among prelacteally fed infants in age periods 0-11, 12-23, and 36-47 weeks. Indiscriminate practice of prelacteal feeding and early supplementation of breastfeeding need to be discouraged.

Abstract. A total of 152 infants were followed from birth to 1 year of age in a rural community of Egypt to document Giardia lamblia infection and to determine the effect of breast-feeding on enteric infections by this protozoan. Asymptomatic Giardia infections persisted as long as 4 months, with a mean duration of excretion of 7.18 weeks. The incidence of asymptomatic infection was 4.5 episodes per child-year. Exclusively breast-fed infants had lower risk for asymptomatic (odds ratio [OR] ϭ 0.66, 95% confidence interval [CI] ϭ 0.45-0.96, P Ͻ 0.05) and symptomatic infections (relative risk [RR] ϭ 0.50, 95% CI ϭ 0.27-0.90, P Ͻ 0.05). Furthermore, breast-fed infants had fewer clinical manifestations, including mucus in stool (23.8% versus 76.2%, P ϭ 0.08), loss of appetite (17.6% versus 82.3%, P Ͻ 0.05), and abdominal tenderness (17% versus 82.9%, P Ͻ 0.05) compared with infants who were not exclusively breast-fed. Breast-feeding should be considered as an effective means to prevent Giardia infections and should be encouraged in regions where G. lambia is highly endemic.

Ankylosing spondylitis is a rather uncommon condition in the UAE. Over a period of 10 years. 28 hospital-based patients diagnosed as having AS were retrospectively studied. They included 17 Arabs and 11 Asians. The onset of AS in most patients in this study was in adulthood (mean age at onset was 27.7 years in Arabs and 28.75 years in Asians). HLA B27 was positive in 56 and 81% in these two populations, respectively (P > 0.05). Analysis of these figures, however, along with previous relevant published data, could indicate that Arabs with AS are less likely to be B27-positive than Asians. Among the Arab patients there was not a single case from the local community, which could be attributed to the extremely low rate of B27 phenotype in their normal population. The interracial variations in the frequency of clinical features were statistically insignificant, therefore indicating some degree of similarity in the form and disease expression in both groups. AS is characterized as being predominantly axial in the majority of our patients. Extraspinal (oligo-poly) arthropathy involved mainly hips and knees, and there have been fewer extra-articular manifestations compared with other series published.
