[Infantile constipation and Allomin-lactulose. Treatment of infantile obstipation in infants fed with breast milk substitutes. A controlled clinical trial of 2 per cent and 4 per cent Allomin-lactulose].

The Authors investigated the effects of Allomin with admixture of 2% and 4% lactulose on constipation in infants aged 0-6 months reared on breast-milk substitutes. The investigation was randomized and double-blind and was carried out during the period 1.4.1987-31.7.1988 on non-hospitalized infants in the counties of Funen and North Jutland in cooperation with the health visitors in these regions. Constipation was defined as hard and difficult defaecation and the trial period lasted for 14 days. Parents of the infants who participated classified the infants' motions according to consistence and degree of difficulty in defaecation on special forms. A total of 220 children participated and these received, after randomizing, either Allomin-lactulose 2% or 4% as the only breast-milk substitute during the period of observation. The effect of treatment was defined as "no constipation" i.e. all motions during 24 hours described as easy and of normal or thin consistence. In addition, the effect was measured by the parents' general impression of what the infant thrived best on. With both of the preparations, treatment was effective in over 90% of the infants in both the groups without significant difference. The effect occurred gradually and, in some cases, up to 8-10 days after initiation of treatment without significant difference in the rate of effect between the groups. After the effect had commenced, significantly fewer thin motions occurred in the 2% group than in the 4% group. 92% of the infants in the 2% group and 91% in the 4% group wanted to continue the Allomin-lactulose preparation rather than the usual breast-milk substitute. A retrospective questionnaire to parents of 97 infants who had continued with Allomin-lactulose 2% was answered by 84.(ABSTRACT TRUNCATED AT 250 WORDS)

Prostaglandin E1 treatment in ductus dependent congenital cardiac malformation. A review of the treatment of 34 neonates.

Thirty-four sick neonates with major duct dependent cardiac defects were given short term (1 h-408 h) intravenous infusions of prostaglandin E1 (alprostadil) in doses varying between 0.1 micrograms/kg/min (starting dose) and 0.01 micrograms/kg/min. The aim of the study was to establish an effective and safe regiment that could be initiated after clinical diagnosis of a severe duct dependent cardiac defect, whose clinical course would be adversely affected by ductus closure. After an initial dosage of 0.1 micrograms/kg/min, effective clinical improvement was achieved in 28 infants (82%). In all 28 responders, the effect was maintained at a reduced dosage of 0.05 micrograms/kg/min, and in 21 a low dosage of 0.01 micrograms/kg/min was effective. Side effects, which occurred in 21 infants (62%), were reversible and dose related, and no serious side effects were noted at a dosage of less than 0.05 micrograms/kg/min. A starting dose of 0.05 micrograms/kg/min with subsequent reduction is recommended, but in case of institution of treatment before transfer to a pediatric cardiac centre a lower starting dose of 0.01 micrograms/kg/min may be preferred.

Diagnosis and treatment of neuroblastoma using metaiodobenzylguanidine.

Neuroblastoma is a lethal and not uncommon tumor in childhood. Early detection and display of the spread of the tumor is highly desirable for proper treatment. Nine children suspected of having neuroblastomas were examined by I-131 metaiodobenzylguanidine (I-131 MIBG) imaging. In two recent studies I-123 metaiodobenzylguanidine (I-123 MIBG) was used. A primary adrenal neuroblastoma was correctly identified in three cases. In two patients additional tumor sites were found. In one patient, who was in complete remission, no pathologic accumulation of I-131 MIBG was found. I-131 MIBG images were also normal in four patients with other types of neoplastic diseases. A boy with multiple metastases was treated with 100 mCi of I-131 MIBG. He developed transient gastrointestinal illness and there was no regression of the tumor deposits. In one girl with a large adrenal neuroblastoma high uptake of I-131 MIBG was observed. She received two therapy doses of I-131 MIBG (35 mCi and 75 mCi) with curative intention giving a total absorbed dose in the tumor of approximately 76 Gy. In spite of high retention of radioactivity in the tumor, regression did not occur, but her general condition was improved. In the present study, images of superior quality were obtained with I-123 MIBG imaging. It is concluded that imaging using I-131 MIBG or I-123 MIBG should be used in both the initial evaluation and the follow-up of children with neuroblastoma.

Diagnosis and treatment of neuroblastoma using 131I-meta-iodobenzylguanidine.

Neuroblastoma is a lethal and not uncommon tumor in childhood. Early detection and display of the spread of the tumor is highly desirable for proper treatment. Nine children suspected of having neuroblastoma were examined by 131I-meta-iodobenzylguanidine (131I-MIBG) scintigraphy. In two recent studies 123I-meta-iodobenzylguanidine (123I-MIBG) was used. A primary adrenal neuroblastoma was correctly identified in 3 cases. In 2 patients additional tumor sites were found. In one patient, who was in complete remission, no pathological accumulation of 131I-MIBG was found. 131I-MIBG scintigraphies were also normal in 4 patients with other types of tumor. In one girl with a large adrenal neuroblastoma high uptake of 131I-MIBG was observed. She received two therapy doses of 131I-MIBG (1300-2800 MBq) with curative intention giving a total absorbed dose in the tumor of approximately 90 Gy. In spite of high retention of radioactivity in the tumor, regression did not appear, but her general condition was improved. In the present study images of superior quality were obtained by 123I-MIBG scintigraphy. It is concluded that scintigraphy with 131I- or 123I-MIBG should be used for primary visualization and control of neuroblastomas.

Transcutaneous PO2 monitoring during treatment with continuous positive airway pressure in infants with idiopathic respiratory distress syndrome.

During a 20-month period, 20 infants with idiopathic respiratory distress syndrome (IRDS) were treated with continuous positive airway pressure (CPAP) when they required at least 40% inspired oxygen. The infants were allocated to monitoring with either repeated blood-gas determinations according to the usual practice or continuous transcutaneous PO2 measurements supplemented by blood-gas measurements only when judged necessary. The groups were comparable with regard to birth weight and gestational age, and did not differ significantly with regard to effectiveness or duration of the CPAP treatment, survival rates (90 versus 80%) or number of complications. None developed retrolental fibroplasia. However, PtcO2 monitoring resulted in significantly less hypo- and hyperoxaemia and the number of blood-gas analyses performed during CPAP therapy amounted to only 0.6 per infant per day in the transcutaneously monitored group as against 5.3 in the other group. We propose that PtcO2 monitoring should now be the method of choice and that the use of umbilical artery catheterization should be restricted to selected groups of very low birth-weight infants and to infants in need of ventilator therapy.

Long-term prognosis of infants with idiopathic respiratory distress syndrome. Follow-up studies in infants surviving after the introduction of continuous positive airway pressure.

Fifty-one children surviving IRDS with CPAP alone or CPAP and IPPV were studied at the age of 2.5 to 4.0 years. One child had developed tetraplegia and mental retardation and 6 children were speech-retarded. Correlation with perinatal events showed that this group of children had a significantly lower gestational age and birth weight, a lower Apgar score and a higher PCO2 prior to ventilatory treatment than the remainder. Re-examination by age 4.0 to 5.0 years showed persistent handicaps in only four of the seven children.

Treatment of respiratory insufficiency in infants using nasal CPAP and a gas jet.

A light-weight system for continuous positive airway pressure (CPAP) based on a nasal vestibular cannula and a miniature gas jet has been tried out in 29 newborns with severe idiopathic respiratory distress syndrome (IRDS) and nine infants suffering from respiratory insufficiency caused by lower respiratory tract infections. In infants with IRDS, a permanent effect was achieved in 20% when the birth weight was below 1501 g, and in 74% when the birth weight was higher. The infants with lower respiratory tract infections all recovered without further ventilatory support. Significant complications occurred in only two infants, both of whom developed pneumothorax. The system forms a simple and safe alternative to existing nasal CPAP systems suitable for use in newborns as well as older infants with lung diseases resulting in alveolar collapse.

Prognosis of neonates with symptomatic respiratory insufficiency surviving with the aid of ventilator therapy.

Twenty-one survivors representing all survivors of neonatal symptomatic respiratory distress treated with intermittent positive pressure ventilation have been follow-up at an age of 2.9 to 7.0 years. The chance of survival proved to be relatively favourable in infants ventilated for perinatal pneumonias and unfavourable in infants ventilated for haemorrhagic diseases and respiratory insufficiency secondary to surgical conditions. At the follow-up half of the children presented with neurological symptoms but only 10% were found severely handicapped. One infant had a tracheostomy due to a laryngeal stenosis, while none developed broncho-pulmonary dysplasia. The late prognosis seemed unfavourable when the children had suffered from severe birth asphyxia and in infants ventilated for prolonged recurrent apnoeic spells. The relation between the clinical indications for ventilator therapy and later outcome is obscured however, by a vase number of complicating perinatal events.
