Maternal weight gain, smoking and other factors in pregnancy as predictors of infant birth-weight in Sydney women.

Two hundred and four (204) women attending a Sydney maternity hospital and their babies were followed throughout pregnancy in a study, which aimed: 1) to describe the distribution of maternal weight gain in present day Australian women and 2) to determine the effect of weight gain and other factors on birth-weight. Maternal weights and skinfold thicknesses were measured serially to give an indication of weight gain. Mean weight gain from conception to term was 14.2kg and mean birth-weight was 3,442g. Maternal predictors of birth-weight such as maternal weight gain, parity, age, education, height, public or private booking status, smoking, prepregnancy weight, and sex of the infant and gestational age were explored using simple and multiple regression analysis. Weight gain was predictive of birth-weight, each kg increase in total weight gain resulting in about a 30g increase in birthweight. Other strong predictors were gestational age, maternal smoking, sex of the infant and maternal parity. Maternal height was less strongly predictive and age and prepregnant weight were not predictive. Smoking mothers had infants who were 268g lighter than those of nonsmoking mothers. However, smokers were also younger, shorter, had less education and were more likely to book as public patients than nonsmokers. After adjusting for all other predictors, the birth-weight of infants whose mothers smoked, was still 224g less than that for nonsmoking mothers.

Infectious mononucleosis in hospitalized patients over forty years of age.

Clinical and laboratory features of 17 patients over 40 years of age (mean age: 55 years) admitted with infectious mononucleosis were compared with those of 17 adolescents (mean age: 13 years) hospitalized with this illness. Elderly patients with infectious mononucleosis were found to run a longer febrile course (13 vs. 7 days, p less than 0.01) and to have a lower peak total white blood cell count (6,600/mm3 vs. 11,000/mm3, p less than 0.001) and a lower incidence of splenomegaly (50% vs. 76%, p less than 0.05), lymphadenopathy (25% vs. 94%, p less than 0.001), and pharyngitis (25% vs. 47%, p less than 0.05), compared with young patients with infectious mononucleosis. Patients in both groups had a high prevalence of abnormal liver function tests. It is concluded that infectious mononucleosis in patients over 40 years of age is not as uncommon as previously reported, and that clinical and laboratory features differ between young and older patients suffering from this disease.

Hydrocortisone resolves persistent neonatal jaundice in multiple hormone deficiencies.

Association of prolonged neonatal cholestasis with hypoglycemia, small penis and congenital hypothalamo-hypopituitary derangement is presented. The infant's jaundice was unresponsive to thyroxine replacement therapy but resolved rapidly with hydrocortisone therapy. The time relationships between persistent jaundice and thyroxine and cortisol deficiencies are discussed.

Dietary patterns of elderly people living in inner Sydney.

The dietary intakes of an elderly non-institutionalized population in inner metropolitan Sydney were collected and analysed. Participants in the study (n = 124) had their midday meal at either an Activity Centre or at home (Meals-on-Wheels Organization). The dietary data was collected over 4 days. Heights and weights and some sociological data were also obtained. The study indicated that a significant proportion of this population may be at nutritional risk, and that this was particularly so for males receiving Meals-on-Wheels.

Effects of mild hyperinsulinemia on the metabolic response to exercise.

To assess the effects of mild hyperinsulinemia on the metabolic adaptations to exercise, five normal male subjects were studied during 2 cycles of 30 min rest followed by 60 min mild exercise. During one cycle, insulin was infused at a rate of 0.33 mU/kg/min. During both cycles, plasma glucose concentration was kept constant by a glucose-controlled glucose infusion system. Studies with and without insulin were performed in random order, with 30 min between studies. During the insulin infusion, plasma non-esterified fatty acids fell during rest and failed to rise with exercise, indicating a limited availability of this substrate to working muscle. Insulin infusion also inhibited the expected rise in glycerol and 3-hydroxybutyrate normally observed during exercise. Plasma lactate concentrations at the completion of exercise with insulin infusion were higher than after exercise without insulin infusion. Greater metabolic dependence on carbohydrate metabolism is suggested by an increased respiratory quotient during insulin infusion. Insulin infusion had no significant effect on the amount of glucose which needed to be infused for maintaining a constant plasma glucose during rest, but there was a large and significant difference in the need for infused glucose during exercise with and without insulin infusion. The results indicate that even mild hyperinsulinism interferes with normal metabolic responses to exercise, and suggest that fall in insulin concentration seen with exercise is an important regulatory process, not merely a secondary consequences of a declining plasma glucose level.

The use of the supraclavicular fossa portal in arthroscopic rotator cuff repair.

SUMMARY: Advances in arthroscopic technology allow rotator cuff repair through a minimally invasive approach. However, fixation of the rotator cuff tendon to suture anchors can be tedious and time consuming. The supraclavicular fossa portal allows improved access to the tear for passing suture. The authors describe the relevant anatomy, positioning, and surgical technique for use of the supraclavicular fossa portal to simplify arthroscopic rotator cuff repair.
