Medical manpower--South African situation models for planning and recommendations.

Imbalances in medical manpower in South Africa are outlined. Theoretical publications on health manpower development are reviewed, with particular reference to factors and problems to be considered when estimating health manpower needs. Four models (health demand, health needs, service target and manpower/population ratio) of health manpower planning are described and their applicability to the South African situation is discussed. Recommendations for health manpower development in South Africa, especially for primary health care, are made.

Follow-up study of physical growth of monozygous twins with discordant within-pair birth weights.

In an attempt to determine the future growth of intrauterine growth-retarded babies, 14 pairs of monozygous twins, showing within-pair birth weight differences of 11% to 48% (median 28%), were followed prospectively for 3 to 9 years. Weight, length, and head circumference were measured biannually for the first 3 years of life and thereafter annually. At birth, the median within-pair percentage differences of weight (28%), length (6.2%), and head circumference (5.2%) were all significant (P less than .01). At 12, 24, and 30 months of age, these median within-pair percentage differences became insignificant for head circumference, length, and weight, respectively. The most rapid catch-up growth of the lighter twins occurred during the first 2 years of life. Analysis of individual pairs, however, showed suboptimal growth in both members of two pairs, although growth became concordant. In four other pairs, the lighter birth weight member remained growth retarded in comparison with the cotwin and showed within-pair differences in weight varying between 8% and 19%, in height between 1% and 6%, and in head circumference between 1.9% and 7%. All children with birth weights above the tenth percentile grew up normally, regardless of the extent of within-pair birth weight differences, with one exception. This exception was a pair in whom there were within-pair differences in child rearing. In the six pairs in which the smaller twin's birth weight was below the tenth percentile, only three pairs showed normal growth. In these six pairs a normal ponderal index in the lighter twin members was associated with poorer growth than a low ponderal index.(ABSTRACT TRUNCATED AT 250 WORDS)

[Small-for-age babies: etiological factors in the Cape colored population].

One hundred and thirty-one small-for-dates Cape Coloured newborns and their mothers were compared with 81 appropriately grown Cape Coloured newborns and their mothers in order to determine aetiological factors in intra-uterine growth retardation. The mothers of the small-for-dates babies differed from the control mothers in the following respects: their postpartum weight and weight for height were less, their placentas were lighter, their incomes were lower, they smoked more heavily, attended antenatal clinics less frequently, and their social conditions, educational status, dietary intake, weight gain during pregnancy and attitude towards pregnancy were inferior. Their previous babies weighed less than the previous babies of control mothers. The study mothers, however, had higher total serum protein, serum albumin and haematocrit levels, which can probably be explained by a smaller plasma volume expansion. The VDRL test on cord blood was more often positive in study babies, but the mean cord blood IgM level did not differ in study and control babies. It is concluded that socio-economic factors play a major role in the aetiology of small-for-dates babies in the Cape Coloured population. Controlled trials of dietary supplementation seem to be indicated in high-risk mothers in this population group.

The need to repeat lumbar puncture.

Four patients with bacterial meningitis are reported. On initial examination 1 patient had a slightly abnormal cerebrospinal fluid (CSF), and in the other 3 patients the CSF was completely normal. An obviously purulent CSF was obtained when lumbar puncture was repeated 14-48 hours later. All 4 patients presented initially with pyrexia, and either neck stiffness or convulsions. In 3 of the 4 patients a cause for pyrexia was found on initial examination but lumbar punctures were done for neck stiffness or convulsions to exclude meningitis. The problems and the need to repeat a lumbar puncture, as well as the importance of blood cultures in a patient with suspected meningitis, are discussed. The fact that a normal specimen of CSF does not exclude meningitis is stressed.

[Intra-uterine growth standards for Cape Colored babies].

Intra-uterine weight, length and head circumference values are reported for Cape Coloured babies. Separate values are given for girls and boys and for firstborns and laterborns. The weight percentile values are lower than those of Scottish babies, but higher than those reported previously for the Coloured population group.
