[Infantile rumination].
Infantile rumination can be defined as self-induced regurgitation of previously swallowed food. Because it can lead to potential somatic complications and because it implies dysfunctional mother-child bonding, both a pediatric and psychiatric approach is needed. The treatment must be somatic (nutritional) and psychological (intensive nursing, mother-baby psychotherapy). Two case studies illustrate this rare but impressive picture.

Myocardial ischaemia in children with sickle cell disease.
BACKGROUND: The heart may be involved in children affected with sickle cell disease (SCD) via several mechanisms. Principally, chronic anaemia increases cardiac output and may cause left ventricular enlargement and cardiac insufficiency. AIMS: To investigate whether the heart also suffers from ischaemia in SCD, as has already been shown for other organs (bone, brain, etc), and to look for risk factors predisposing to this complication. METHODS: Twenty two children with SCD, and chest pain or ECG or echocardiographic signs (left ventricle dilation or hypokinesis) suggesting myocardial ischaemia were subjected to thallium-201 (201Tl) single photon emission computed tomography (SPECT). RESULTS: Eight children had a normal SPECT, 14 an abnormal one. Myocardial perfusion defects were reversible in nine, fixed in five. Patients with perfusion defects tended to be older and have more severe disease. Five had had cardiac symptoms (episodes of cardiac failure in three, ventricular fibrillation in one, angina in one). Myocardial perfusion was reassessed after six months of hydroxyurea treatment in three patients, and was found to be improved. CONCLUSIONS: Myocardial perfusion defects are present in children with SCD and may be demonstrated using SPECT. Hydroxyurea improved perfusion in three patients.

[Pertinence of the 2000 WHO criteria in non-immune children with severe malaria in Dakar, Senegal ].
UNLABELLED: The relevance of World Health Organization (WHO) criteria for severe malaria has not been assessed in non-immune children. The objectives of this study were (i) to evaluate the significance of 1990 WHO definition reconsidered in 2000 on distribution and lethality of severe cases in children admitted with falciparum malaria, and (ii) to contribute to the study of relevance of the WHO severe criteria in Dakar, an hypoendemic area in Senegal. PATIENTS AND METHODS: The 1990 WHO criteria, respiratory distress and platelet counts were prospectively collected in 1997-99 from children admitted to Hôpital Principal de Dakar, Senegal, with falciparum malaria diagnosed on a thick blood film. This method allowed also the definition of severe cases according to 2000 WHO criteria. RESULTS: Among 311 patients (median age: 8 years old), according to the 2000 WHO criteria, the frequency of severe malaria cases was increased by 23% (75% versus 52%) and case-fatality rates thereof were decreased by 5% (17% versus 12%) compared with 1990 WHO definition. One death occurred among cases defined as severe on admission only according to criteria modified by WHO in 2000. A multivariate logistic regression model identified several independent prognostic factors: cerebral malaria, hypoglycaemia, respiratory distress, renal failure, collapse, abnormal bleedings, pupillary abnormalities and thrombocytopaenia defined as a platelet count below 100,000/mm3. A significant association (p < 0.001) was observed between platelet count increase and consciousness level improvement, evaluated on day of first platelet count control (time from admission: 1-7 d). Among survivors, a lesser improvement in coma score was associated with a decrease in platelet counts (p < 0.04). CONCLUSIONS: The 1990 WHO criteria, which predicted death among malaria cases in children living under stable falciparum transmission, are relevant in this series of non-immune children living in a low and seasonal transmission. Nevertheless new WHO criteria showed poor prognostic significance. However, the 2000 WHO definition was highly sensitive to detect severe malaria cases. These findings should be considered for managing severe malaria in migrant children.

[Evaluation of long-term outcome of Senegalese children sent abroad for cardiac surgery].
The incidence of childhood heart disease in developing countries is high, but access to cardiac surgery is limited. This mismatch has given rise to numerous humanitarian programs aimed at sending children abroad for surgical treatment. However little is available about the long-term outcome of these interventions. In 1999 we conducted a retrospective study of 168 Senegalese children undergoing follow-up at the Principal Hospital in Dakar after being transferred to Europe or the Ivory Coast for surgical treatment thanks to the Terre des Hommes Association. A total of 85 children presented congenital heart disease (CHD) and 83 presented acquired heart disease (AHD). Fifteen patients did not undergo surgery due to either contraindications or preoperative death. At the end of study, 23 children had been lost to follow-up mostly from the CHA group and presumably some were cured. Outcome was verifiable in the remaining 145 patients with a median follow-up of 5.6 years. Ninety-seven patients were cured or undergoing surveillance. Quality of life was better in the CHD group (p = 0.047). Forty-eight patients died including 16 in the CHD group and 32 in the AHD group. Perioperative mortality (n = 19) was lower and late mortality (n = 29) was higher in the AHD group (p = 0.005). In the AHD group compliance with surveillance was better for children with valve prostheses. In children treated for isolated mitral valve insufficiency, late mortality was higher after valve replacement than valve repair (p = 0.04). In absence of comparative study data, high mortality was due in part to the long delay between the decision to send the patient abroad and the actual evacuation. These findings support humanitarian action to promote cardiac surgery in developing countries.

[Prion diseases in pediatrics].
Prion diseases are rare neurologic affections with a poor prognosis, occurring in both humans and animals. Creutzfeldt-Jakob disease (CJD) secondary to human extracted growth hormone treatment is the most frequent condition in pediatrics. In 1994, a new type of CJD (variant CJD) was described in young adults in the United Kingdom, only 10 years after the bovine spongiform encephalopathy epidemic, with recent works showing a direct relationship between the bovine epidemic and the human cases. An accumulation of a single protein called the prion protein (PrP) has been discovered in the brain in all of these cases, animal and human, leading to the hypothesis that a new infectious agent could proceed without any nuclear acid information; another hypothesis is that of a still unknown viral agent. The PRNP gene encoding for this PrP protein is well described: some mutations and a polymorphism in the 129th codon have been shown to be implicated in many cases of CJD. PrP is a ubiquitous protein, with yet unknown physiological function. There are still many questions to be answered: shall we expect new pediatric cases of variant CJD? Assuming that animal-human contamination is related to alimentation, are there other ways of contamination.

Severe falciparum malaria in children: a comparative study of 1990 and 2000 WHO criteria for clinical presentation, prognosis and intensive care in Dakar, Senegal.
The relevance of WHO criteria for severe and complicated malaria has been debated for a while, especially as regards children. Recent data led WHO experts to modify the definition of severe malaria. The objective of this study was to evaluate retrospectively the significance of the new definition on severity, lethality and intensive care distribution in children admitted with falciparum malaria (in 1997-99) to Hôpital Principal de Dakar, Senegal. We used the paediatric risk of mortality score (PRISM) to compare the 2 definitions, WHO 2000 and WHO 1990. Finally, we evaluated the impact of the new definition in terms of major therapeutic interventions (MTIs): mechanical ventilation, haemodynamic support, transfusion, haemodialysis, and the use of sedatives. Among 311 patients, the frequencies of severe malaria cases and case-fatality rates thereof were 52% (n = 161) and 17% (n = 28) respectively using the 1990 WHO criteria, and 75% (n = 233) and 12% (n = 28) using the 2000 WHO criteria. Mean PRISM score among severe cases decreased with the new definition (6.5 versus 8.6). Both definitions predicted neurological sequelae and deaths with 100% sensitivity. One or more MTIs were required in severe malaria cases in 86% (n = 139) under the 1990 criteria and 73% (n = 170) under the 2000 criteria. In this area of low and seasonal transmission, the 2000 WHO definition of severe malaria proved broader and less specific, but was easier to apply and retained the high sensitivity of the earlier definition in identifying life-threatening infections.
