Growth hormone treatment in short children with intrauterine growth retardation.

The aim of this prospective controlled study was to assess the effect of rhGH in short prepubertal children with intrauterine growth retardation and normal growth hormone status. Twenty-six children were randomized into treatment (12F, 4M) and control (6F, 4M) groups. Mean ages were 5.3 (1.3) yr and 4.3 (1.7) yr, respectively. rhGH (Genotropin) was used at a dose of 0.2 IU/kg/day as daily s.c. injections for two years. In the treated group, mean height SDS increased from -3.0 (0.5) to -1.9 (0.7) and height velocity SDS showed a significant increase from -1.3 (2.0) to 3.7 (1.8) in the first year (p < 0.001) and 1.6 (1.8) (p < 0.01) in the second year of treatment. In the controls, height SDS, initially -2.7 (1.4), and height velocity SDS, initially -0.9 (1.1), remained essentially the same during two years of follow-up. Height SDS for bone age changed by 0.6 in the treated group and 0.4 in the control group. Target height SDS--initial height SDS in the treated group improved by 1.1 SD but declined in the control group. IGF-I levels increased from 9.5 (4.2) nmol/l (72 [31.8] ng/ml) to 32.5 (27.0) nmol/l (244.4 [202.8] ng/ml) (p = 0.004) in the treated group while no change was observed in the controls. No adverse effects were encountered during rhGH therapy. It was concluded that rhGH treatment induces a significant increase in growth velocity in the short term. This outcome, as opposed to the unchanged indices in the control group over the same period, may be indicative of an improved height prognosis in short children born with intrauterine growth retardation treated with rhGH.

Ten steps for successful breast-feeding: assessment of hospital performance, its determinants and planning for improvement.

This paper discusses results from a project which aims to document the maternity hospital practices in istanbul within the context of Ten Steps for Successful Breastfeeding. Instruments developed for use in hospital level implementation of the WHO/UNICEF baby friendly hospital initiative were used in five hospitals (two public and three private). No hospital was implementing all Ten Steps. A core hospital team on lactation management and a sufficient number of health personnel skillful in breastfeeding counselling and adequate delivery room conditions are required to implement the Ten Steps. It is very difficult to provide these conditions in public hospitals with an excessive patient load. On the other hand, the fee for service system and the policy of changing practices according to the wishes of the clients can also become barriers to successful breastfeeding, as may occur in some private hospitals.

beta-Endorphin and some hormonal levels in children with acute stress hyperglycaemia.

The levels of beta-endorphin, insulin, cortisol, GH, glucagon, prolactin and TSH were measured in serum samples of 9 hyperglycaemic patients (3 female, 6 male) with a mean age of 4.1 years admitted to the pediatric emergency unit. All patients were in acute stress due to severe diseases (acute gastroenteritis, bronchopneumonia, septicaemia, etc.). Initial and repeat blood samples for hormone determination were taken at admission and in the recovery phase (after 4-6 weeks of treatment). OGTT was also performed in the recovery phase. The hyperglycaemia, monitored hourly following the initial determination, returned to normal in all patients in 1-5 h without specific treatment. Mean serum glucose values at admission and in the recovery phase were 287.0 and 84.1 mg/dl. Concomitant to the hyperglycaemia encountered in these patients in the acute phase of stress, an increase was noted in all hormone levels excluding glucagon and cortisol. All elevated hormone levels fell to normal in 4-6 weeks with significant differences from initial levels for beta-endorphin (P < 0.05) and insulin (P < 0.01). OGTT gave a normal curve. These results indicate that stress hyperglycaemia, despite high insulin levels, is associated with an increase in beta-endorphin levels. The results also show that hyperglycaemia in acute disease does not alter OGTT in short-term follow up.

Trial of co-trimoxazole versus procaine penicillin G and benzathin penicillin + procaine penicillin G in the treatment of childhood pneumonia.

This study, which aimed to assess the results of three different regimens in the treatment of pneumonia, was carried out at the Pediatric Outpatient Department of Capa Children's Hospital in Istanbul on 151 patients aged between 4 months and 14 years. The first group (n = 46) received co-trimoxazole orally for 10 days and the second group (n = 63) procaine penicillin G in intramuscularly for 10 days. Benzathin penicillin G combined with procaine penicillin G was given to the third group (n = 42) as a single dose intramuscularly. While the best results were obtained with penicillin procaine G, no statistically significant difference was found between this regimen and co-trimoxazole therapy (chi 2 = 0.305023 P = 0.5). We suggest that co-trimoxazole is easy to administer and cost effective in the ambulatory treatment of pneumonia in children.

Carbohydrate malabsorption in acute diarrhea.

A group of 245 well nourished infants with acute diarrhea were screened for carbohydrate malabsorption by evaluating stool pH and reducing substances in the stools. Carbohydrate malabsorption was diagnosed in 28 cases (11%). Clinical features of carbohydrate intolerance were present in only one case. The duration of diarrhea after admission ranged from 1 to 13 days (mean 3.9 days). An oral lactose tolerance test was consistent with lactase deficiency in 32% of all cases. Thin layer chromatography showed many carbohydrates including monosaccharides in the stools, indicating that the defect in intestinal absorption was not specific for lactose.

Estimation of annual height velocity based on short- versus long-term measurements.

We assessed the relationships between annual height velocity, calculated from two measurements taken at intervals of 6, 12 and 24 months, in 69 healthy prepubertal children (34 male, 35 female) aged 6.5 years (range 6.25-6.75 yrs) who were followed for 2.5 years and measured biannually. Initial height values for age were within normal ranges except for one child with a height SDS of -2.0. Mean annual velocities also conformed to British norms. Significant differences were observed between consecutive six-monthly velocities and these values failed to predict annual velocities calculated from measurements taken at 12- or 24-month intervals. Seasonal effects were thought to have some impact on the six-monthly velocity differences. Height velocity, based on measurements taken at intervals of 12 months, was essentially similar to two-year velocity values. The results indicate that in estimating annual height velocity, six-month intervals between measurements may be misleading while 12-monthly measurements are as reliable as height velocity values based on measurements taken at two-year intervals.

Growth response to growth hormone-releasing hormone(1-29)-NH2 compared with growth hormone.

To assess the growth-promoting effect of different doses of growth hormone-releasing hormone(1-29)-NH2 (GHRH(1-29)-NH2) in GH deficiency (GHD) of hypothalamic origin, 43 prepubertal children aged between 4.3 and 18.9 years (mean 10.4 +/- 2.9 years) were randomly assigned to three treatment regimens: low-dose GHRH(1-29)-NH2 (LD group; n = 15), high-dose GHRH(1-29)-NH2 (HD group; n = 12) and GH (GH group; n = 16). The LD group received GHRH(1-29)-NH2 at 30 micrograms/kg/day s.c. in three daily doses, the HD group received 60 micrograms/kg/day s.c. in three daily doses and the GH group received GH, 0.1 IU/kg/day s.c. once daily. All children were treated for a period of 6 months. Evaluation included anthropometry, bone age, intravenous and subcutaneous GHRH(1-29)-NH2 tests and determination of insulin-like growth factor I (IGF-I) levels. An increase in height velocity of 2 cm/year or more was observed in all except two children. Height velocity during treatment was lowest in the LD group, but comparable in the HD and GH groups. An increase in height SDS for bone age occurred only in the GH-treated group. GH responses to intravenous GHRH(1-29)-NH2 showed a priming effect of the LD GHRH(1-29)-NH2 treatment, while a decrease in response occurred in the GH-treated group. Following a subcutaneous test dose of one-third of the daily dose of GHRH(1-29)-NH2, GH levels remained unchanged in both the LD and HD groups. There was accumulation of GHRH immunoreactivity over time in the HD group, but there was no correlation between measured GHRH and GH levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Paraprofessional women as health care facilitators in mother and child health.

The aim of the study was to compare the performance of midwives with that of lady home visitors (LHV; paraprofessionals). The project area was divided into six according to the population map. One midwife or one LHV was assigned to each visiting area. Home visits were carried out to identify and offer guidance on family planning (FP), antenatal care, well-child control, immunizations and other mother and child health related issues to those at high risk. Criteria taken for evaluation were the numbers of pregnant women identified in the last trimester; pregnant women receiving antenatal care; deliveries attended by a health care provider; modern FP users; continuation rate of the new users; pregnancy rate in new users; immunization status of children; well-child visits of the children. No significant differences were found in these health measurements between areas visited by LHV and areas visited by midwives. Response rates to the invitation was also similar in both areas. An important observation was the good performance of the LHV in communicating with the families. Women with limited school attainment from the community can be used effectively and efficiently in community health services.

Development of Kasabach-Merritt syndrome following needle aspiration of a hemangioma.

A case of Kasabach-Merritt syndrome that developed following needle aspiration in an infant with hemangioma is presented. Enlargement of the tumor leading to severe respiratory distress accompanied by hemorrhages occurred within six to eight hours after this simple intervention. The symptoms continued despite repeated thrombocyte transfusions and prednisolone therapy. Radiotherapy and local intraarterial corticosteroid therapy were attempted and led to some improvement. It took approximately three months for the platelet count and one year for the clinical state to revert to normal. This case illustrates that minor trauma may lead to life-threatening symptoms in a young infant with congenital hemangioma.

Experiences of a health team working in a new urban settlement area in Istanbul.

A project aiming at creating a model for comprehensive maternal and child health care for urban underdeveloped areas was started in a new settlement area of migrants in the vicinity of Istanbul. The project had an impact on health care status, particularly among infants and children, but the results indicated that more effort was needed to reach the mothers. It was noted that building space and the appearance of the work place influenced the prestige of the team. Absentee problems could be partly surmounted by repeated home visits. Based on this experience, it was concluded that health services in underdeveloped areas need to be supported by non medical personnel to act as home visitors and as mediators between the community and the health team. It was also concluded that an established recording system to include both clinical data and attendance is needed to define the cases who need special care.

An educational intervention on promotion of breast feeding.

This study was designed to search for an effective method to promote exclusive breast feeding among Turkish city women delivering in hospitals. Four hundred and forty-two primiparae with uncomplicated deliveries and with healthy infants with birthweights of greater than 2500 g were exposed to a group educational session on breast feeding after birth, followed by one repeat session at home. Four hundred and ninety-nine women served as controls. All homes were visited monthly for 6 months by independent observers and data relevant to the feeding of the infants were collected. Weight measurements of 176 infants were taken at age 4 months. The study and control mothers were similar in sociodemographic characteristics which reflected a low socio-economic/educational background but relatively good housing conditions. Although significant differences in frequency of exclusive breast feeding were found between the study and control groups, the impact of the intervention was much lower than our expectations and short-lived. Type of feeding was not related to sex or birthweight of the infant, nor to maternal variables. Weight at age 4 months was within normal limits and similar in the study and control groups. It was concluded that lack of up-to-date information on infant feeding was the main obstacle to breast feeding in urban groups in Turkey, and that the impact of an educational intervention limited to the first week after delivery was lost within the first 2 months.

An educational intervention on promotion of breast feeding complemented by continuing support.

The study, aiming to document the effect of continued support for mothers on frequency of exclusive breast feeding, was carried out by inclusion of breast feeding counselling in the context of well-baby care. One hundred and forty-six mothers who had been exposed to two educational sessions on breast feeding after delivery were given appointments to bring their baby to the paediatric hospital for well-baby care. The mother-infant pairs were followed by the same two residents for 4 months. Mean number of visits was six. A conscious effort was made during all visits to influence the mothers and their close relatives towards exclusive breast feeding. It was observed that in a large proportion of the infants, breast milk was being supplemented with water at the time of the first visit and no further effort was made to change this traditional behaviour. Comparison of the results with a group of mothers who had been exposed to similar educational sessions after delivery but without further support showed a striking increase in frequency of exclusive breast feeding (breast milk and water) in the supported group.

Oral rehydration therapy: studies on potassium balance.

The clinical response and changes in potassium balance were studied during oral rehydration therapy (ORT) with a solution containing 20 mmol potassium per litre in well-nourished and malnourished infants of 3 to 15 months of age as well as in neonates and young infants less than 2 months old (range 5-60 days). All infants were successfully rehydrated orally. The potassium intake considerably exceeded the potassium output in all groups during the entire rehydration period. The stool and urine potassium output were about the same in the 3 groups of patients. The retention of potassium increased during ORT in all groups at about the same rate. The study thus demonstrates that an oral rehydration solution (ORS) containing 20 mmol potassium per litre provides enough potassium to all patients. An increase in the potassium concentration of the ORT is therefore not recommended.

Beta-endorphin levels of children in acute stress.

In this study aiming to clarify the relationships between beta-endorphin and glucose levels, beta-endorphin levels were determined in children in acute stress. The study was carried out on 32 critically ill children between 5 days and 12 years presenting with clinical symptoms of acute infectious conditions. 11 healthy children were taken as controls. The results showed that although beta-endorphin levels were elevated in all critically ill patients, these levels were significantly higher than control values in hyperglycaemic cases. The insulin levels were also elevated. A follow-up of nine of the hyperglycaemic cases showed a significant decline in beta-endorphin and insulin levels with recovery. Glucose tolerance was also normal. These results confirm the reports of many other studies on the role of beta-endorphin as a stress hormone.
