[Epidemiologic study of strabismic amblyopia in Tunisia].

The authors study 202 strabismus cases and evaluate the strabismic epidemiology of Tunisia: 58% of squint children have amblyopia. The low vision is important, and getting worse with age. The treatment is simple, consisting of occlusion of the good eye, but it become longer and more difficult after six years. The best results are obtained in the first four years. Good cooperation from the parents is required. The authors insist on the necessity of early detection through testing, the prevention of recurrence and, above all, on preventing the advent of amblyopia as soon as strabismus appears.

[Fetal macrosomia and the study of risk factors in maternal diabetes].

The authors report the results of a study performed in 142 women who gave birth to overgrown neonates. Among them, the incidence of diabetes was high: 7.75%. Older maternal age, maternal obesity and the former birth of large infants were also found to be risk factors for fetal overgrowth.

Milk and lactation: some social and developmental correlates among 1,000 infants.

Breast-feeding and artificial feeding practices in a developing country were examined and related to some social and developmental factors. This was done during the course of a transverse-type growth study of 1,000 infants from birth to 26 months of age. Three types of feeding were identified: breast, mixed, and artificial. The families were divided into three social categories. To give time for the effects of the type of feeding, groups of children at 6, 8, 10, 12, 14, and 16 months of age were studied. In view of the lack of data on feeding effects upon large samples, the study was performed to assess the relative effects of feeding on early childhood development (Bayley Motor and Mental Scales), body length and weight, disease prevalence, clinical signs of allergies, and number of children in the family. Results showed that within the underprivileged group, there was evidence that breast-feeding promoted physical growth, sensory motor development, and resistance to infection. In mothers of both male and female infants who breast-fed, there was a protective effect against subsequent pregnancy up to ten months. Therefore, among the underprivileged in developing countries, every effort should be made to prolong breast-feeding and to assist mothers with health and nutrition education.

[Low birth-weight neonates in Tunisia (author's transl)].

From a prospective analysis performed in a maternity-hospital in Tunis, incidence, characteristic features and etiologic factors responsible for birth-weight below 2,5000 g have been studied. Incidence of low birth-weight is accepted as an indicator of the level of health care in a country; this incidence, established from 6,028 living births was 7.2%, similar to that in developed countries. On the contrary, intra-uterine growth retardation rates of 69.6% and prematures rates of 30.4% are closer to those in developing countries. Altogether, anomalies of height and of the height/head circumference ratio were present in 36 children only and, in 12 out the these, abnormalities of the placenta or membranes or evidence of fetal disease were found. A factor responsible for low birth weight was found in 182 neonates: previous severe disease in the mother (7.7%), toxemia (9.4%) twin pregnancy (22.41%), fetal pathology (3.5%) and pathology of the placenta and membranes (4.6%).

[Cellular immunity in protein-caloric malnutrition].

In order to have a clearer idea on the relationship between infectious diseases and malnutrition, cellular immunity is studied in 3 to 18 months old malnourished and healthy infants. Nutritional status is evaluated by the food intake the anthropologic measurements and some biological parameters like transferrin. Cellular immunity is investigated by skin tests to tuberculin, monilia, P.H.A. and DNCB. Absolute number of peripheral lymphocytes and percentage of T cells are studied too. The results show that there is a cellular immunity deficiency: frequent non-response to antigens, weak sensitization to DNCB. Some patients have a low percentage of spontaneous rosettes. The transferrin titering is useful to appreciate the nutritional status and the iron therapy opportunity, the prognostic and the immunitary possibilities.
