Recurrent chest pain as the presenting manifestation of spinal meningioma

We report the case of a 9-year-old boy with a spinal cord meningioma whose only manifestations were recurrent episodes of chest pain lasting for 2 years. This case shows that spinal cord meningioma should be considered among the possible causative factors of chronic chest pain in childhood. Chest pain, meningioma, spinal tumors     

AIDS: outcome of children born to HTLV-III/LAV infected mothers. Report of 15 Italian cases

The characteristics of acquired immunodeficiency syndrome (AIDS) in children have been described in several reports. The occurrence of specific anti-HTLV-III/LAV seropositivity in children born to seropositive mothers is also becoming more frequent in Italy. We report 15 cases of seropositive children born to 14 seropositive, drug-addicted mothers. Among them, 5 died of AIDS, 8 developed a variable, non-progressive AIDS-related complex (ARC), while only two remained persistently asymptomatic. Liver disease was present in 2 patients, CNS disease in 4, gastrointestinal troubles were never a major problem. Only 2 cases of HBV infection and 3 of thrombocytopenia were observed. In our experience, homosexual behaviour of the parents was never a cause of family risk. Children presented with failure to thrive and/or signs of disease usually within the first five months of life. In one family the first child was affected by fatal AIDS while the younger child showed only passive, transient immunization by maternal specific IgG. One ARC patient, observed for over 3 years, showed apparently complete healing from the disease.     

Survey of the definition and screening of neonatal hypoglycaemia in Australia

Objective : To determine the approach to identifying neonatal hypoglycaemia and the definition of neonatal hypoglycaemia used by neonatal paediatricians in Australian Level 3 neonatal intensive care units (NICU).
Methodology : A questionnaire was sent to the 101 neonatal paediatricians in the 22 Level 3 NICU in Australia asking their method of screening for, and definition of, neonatal hypoglycaemia.
Results : Responses were received from 70 neonatal paediatricians, including all 22 directors. A bedside glucose meter is used in 19 of 22 NICU to screen for hypoglycaemia, whilst one NICU uses a glucose analyzer and another NICU uses a visual colour comparison method. One NICU does not screen, but has blood glucose measured in a satellite laboratory. If the screening method suggests hypoglycaemia, 62 of 63 neonatal paediatricians proceed to blood glucose determination in a laboratory, mostly using plasma samples. Based on the laboratory measurement, the definition of neonatal hypoglycaemia ranged from <1.1 to 3.0 mmol/L.
Conclusions : The majority of neonatal paediatricians in Australian NICU screen for neonatal hypoglycaemia using a bedside glucose meter. There is a wide range in the definition of neonatal hypoglycaemia from <1.1 to 3.0mmol/L.     

R. Daudt, G. L. Von poser, G. Neves and S. M. K. Rates, 'Screening for the antidepressant activity of some species of hypericum from south Brazil'. Phytotherapy research14(5) 2000, 344-346

The original article to which this Erratum refers was published in Phytotherapy Research 14(5) 2000, 344-346. Following the publication of this paper in the August 2000 issue of Phytotherapy Research (14(5):344-346), it has come to our attention that there is a misleading statement regarding conclusions cited from the work of Butterweck et al. 1998. The discussion in the recent PTR paper states that those authors are 'in favour of the hypothesis that the antidepressant activity is due to the hypericin only'. We wish to make it clear that this is not the case, and the Butterweck paper actually concludes that 'both naphthodianthrones must be considered as active constituents of the crude extract of H. perforatum. However, previous studies indicate that the other consitutuents of the crude drug also have activity'. The authors apologize for this error and are happy to correct it.     

ANTEROVENTRAL WALL OF THE THIRD VENTRICLE AND DORSAL LAMINA TERMINALIS: HEADQUARTERS FOR CONTROL OF BODY FLUID HOMEOSTASIS?

1. The subfornical organ, median preoptic nucleus and the organum vasculosum of the lamina terminalis (OVLT) are a series of structures situated in the anterior wall of the third ventricle and form the lamina terminalis. The OVLT and ventral part of the median preoptic nucleus are part of a region known as the anteroventral third ventricle region.
2. Data from many laboratories, using techniques ranging from lesions, electrophysiology, neuropharmacology, Fos expression, immunohistochemistry and receptor localization, indicate that the tissue in the lamina terminalis plays a major role in many aspects of body fluid and electrolyte balance.
3. The subfornical organ and OVLT lack the blood-brain barrier and detect alterations in plasma tonicity and the concentrations of circulating hormones such as angiotensin II and possibly atrial natriuretic peptide and relaxin.
4. This information is then integrated within the lamina terminalis (probably in the median preoptic nucleus) with neural signals from other brain regions. The neural output from the lamina terminalis is distributed to a number of effector sites including the paraventricular (both parvo- and magno-cellular parts) and supraoptic nuclei and influences vasopressin secretion, water drinking, salt intake, renin secretion, renal sodium excretion and cardiovascular regulation.     

Oral rehydration solutions in gastroenteritis before and after admission to hospital

Two recent studies published in this Journal draw attention to deficiencies in treatment of children with acute infectious diarrhoea in Australia.^1,2 There is now no doubt that use of correctly constituted oral rehydration solutions provides optimal therapy for affected children unless circulation is compromised, vomiting is more than average, or complicating disorders are present. In the vast majority of cases, these complications do not occur. A high proportion of the childhood population experiences gastroenteritis at some time. It is known that 50% of Melbourne children require medical attention for rotavirus infection alone during their first 3 years of life, although less than 5% require admission.
