Abstract
OBJECTIVE This study had for aim to determine the etiology of Haemophilus b pediatric meningitis. DESIGN A retrospective study of 216 biologically confirmed cases was carried out during 6 years (January 1995- December 2000) on children 0 to 15 years of age, hospitalized at the Albert Royer Children Hospital Center. RESULTS Haemophilus influenzae b is the first cause of pediatric meningitis (19.7%) followed by Nesseria meningitidis (14.5%), and Streptococcus pneumoniae (13.6%). The Haemophilus influenzae b meningitis cases are distributed all year round with a peak between January and March, that is to say, during the dry and cool season. They affect children at an average age of 11.7 months, with a sex ratio of 1.1 for boys. Almost all of the patients live in the low-socio-economic areas of the Dakar suburbs (92.8%). More than 90% of the H. influenzae b isolates are sensitive to ceftriaxone (96%) chloramphenicol (93%), and to ampicillin (91%). Clinical evolution is marked by death (17.8%) and recovery with psychological, sensory, and motor sequels (19.9%). CONCLUSION This report should help to include the combined vaccine Antihaemophilus influenzae b in the Senegalese Broad Vaccination Program. The final aim is the reduction of morbidity and mortality of infections due to Haemophilus influenzae b.

Abstract
BACKGROUND In vitamin A-deficient populations, children hospitalized with infections and/or malnutrition are at particular risk of developing severe vitamin A (VA) deficiency. High-dose VA supplements are recommended as part of the treatment but results on its effect on recovery from morbidity and on prevention from nosocomial morbidity are conflicting. OBJECTIVE We aimed to assess the effect of a single high dose and daily low dose of VA on hospitalized malnourished children's morbidity. DESIGN We carried out a double-blind, randomized trial in 604 and 610 Senegalese hospitalized children. The first mentioned batch received a high-dose VA supplement (200,000 IU) on admission, the second a daily low-dose VA supplement (5000 IU per day) during hospitalization. Children were followed up until discharged. Data on all-cause morbidity were collected daily. RESULTS Survival analysis showed that the incidence of respiratory disease was significantly lower in the low-dose group than in the high-dose group, hazard ratios (HR): 0.26, 95% CI: 0.07-0.92. The duration of respiratory infection was also significantly lower in the low-dose group than in the high-dose group (HR of cure: 1.41, 95% CI: 1.05-1.89). Duration and incidence of diarrhoea were not significantly different between treatment groups. In children with oedema on admission, mortality was significantly lower in the low-dose group (Adjusted odds ratio: 0.21; 95% CI: 0.05-0.99). CONCLUSIONS Daily low dose of VA compared with single high dose significantly reduced duration and incidence of respiratory infection but not of diarrhoea in hospitalized children.

Abstract
A case-control study was conducted between September 2003 and January 2004. Fifty four newborn babies born before 37 weeks of gestation resulting from 47 pregnancies including 7 multiple pregnancies were compared to 105 newborn babies born between 37 and the 42 weeks of gestation. Parturient geographical origin, marital status, age, alcohol or tea consumption and height were not significantly associated to premature birth (p > 0.05). On the other hand, a higher parity or equal to 3, a number of antenatal care lower than 3 were significantly associated with the risk of premature birth (p < 0.05). But a gestity and a parity lower than 3 and a number of antenatal consultations higher or equal to 3 had a protective effect (OR < 1; p < 0.05). We recommend a reinforcement of malarial prevention during pregnancy according to WHO recommendations and the improvement of the quality of the antenatal care in the Ziguinchor medical district.

Abstract
AIM OF THIS STUDY to evaluate the efficacy of kangaroo method on thermoregulation and weight gain of a cohort of preterm. METHODS it is a retrospective study based on files of preterm baby weighting below 2000 g, included after discharge to neonatal unit of Aristide Le Dantec maternity for kangaroo method care. Efficiency was appreciated on thermic curve evolution and daily weight gain. RESULTS 56 preterm babies were including. Mean gestational age was 33 +/- 7,6 weeks and mean birth weight, 1488 +/- 277,6 g (median = 1500 g). Mean temperature was satisfying during follow up and was stable around 37 +/- 0,5 degrees C at discharge of program with mean daily weight gain of 33 +/- 7,6 g. We had only one case of death. CONCLUSION The results of this study point out efficacy of kangaroo method on thermoregulation, weight gain and survival of preterm babies. We advocate for promotion in developing countries because of its low cost.

Abstract
BACKGROUND Beckwith-Wiedemann syndrome is a congenital syndrome with variable phenotypic expression. It is less commonly described in Africa. We report a case in Dakar universitary hospital center. OBSERVATION This report is about a two month old child from Mauritania presenting an hemihypertrophy, macroglassia and an umbilical hernia. Glycemia was under normal level showing a mild hypoglycemia (0,6 g/dl). T3, T4 and TSH values were in normal range. Abdominal echography was normal. Our patient was stable at the first clinical examination. CONCLUSION we advocate for dietetic measures and rigorous clinical follow up, every 3 to 6 month, to screen for recurrent hypoglycaemia and the occurence of an eventual neoplasmic desorders.

Abstract
BACKGROUND Acute respiratory infections are the leading cause of death in childhood and most child deaths in Senegal occur at home without qualified health care. Despite this situation, only qualified healthcare workers are authorized to prescribe antibiotics. A competency-based training program was developed to improve and assess management of acute respiratory infections in young children aged between 2 and 59 months by low-level educated community health workers (CHWs) in four districts of Senegal. METHODS In accordance with the strategy developed by the World Health Organisation, educated low-level community health workers in four district of Senegal were given a three-day course on the management of acute respiratory failure. We assessed the effects of the course by comparing pre-training and post-training skills with the Students t test. RESULTS The results showed that the educated low-level community health workers were capable of acquiring the skills needed to effectively manage children with acute respiratory failure. CONCLUSION Further evaluation is needed to determine the mid- and long-term effects of the course and supervised post-training activities.

Abstract
The aim of this study is to assess mortality rate of low birth weight newborns admitted to a neonatal care unit of Dakar after transfer. This retrospective study include all newborns weighing less than 2500 g transferred to Abass Ndao neonatal care unit between January 1st,1998 and December 31, 1999. Maternal, newborns and transfer related parameters were studied. Data of 180 new-borns were recorded from a sample of 247 babies transferred. The mean weight of these babies were 1452.5 +/- 432 g. An ambulance was used for transport in only 10% of cases. The median time of admission after birth was 3 hours. Median delay of admission and methods of transfer, maternal age and parity, apgar score at 1st and 5th minute were comparable between the newborns deceased and survivors (p > 0.05). To reduce mortality associated with newborns transfer, we insist on a better organisation of neonatal transport in under developed countries by promoting obstetricians and paediatricians collaboration and prevention of low birth weight.

Abstract
Management of major sickle hemoglobinopathies in industrialized countries has improved significantly over the last few years thanks to strict application of the preventive and curative measures developed as a result of a better understanding of the underlying pathophysiological mechanisms. However patients in Africa have benefited little from progress in the field due to the lack of human and physical resources in sharp contrast with the high prevalence of the disease. The purpose of this study was to analyze problems involved in management of childhood sickle cell disease in Africa based on our experience in a cohort of 556 cases treated over a period of 12 years. The main problems were the same as those encountered in other black African nations, i.e., delayed diagnosis due to a lack of routine neonatal diagnostic screening, difficulty implementing anti-infectious prophylaxis due not only to the high cost of recommended vaccinations not covered by the Expanded Program on Immunization but also to poor compliance with antiobioprophylaxis, and insufficient transfusion facilities hindering application of long-term transfusion protocols when indicated. In addition the high prevalence of digestive-tract parasitosis and malaria raise the need to combine standard preventive measures with routine parasiticidal treatment and malarial prophylaxis adapted to each geographical area. The high frequency of associated iron deficiency requires systematic laboratory testing to identify and treat resulting manifestations during follow-up. An important prerequisite for widespread implementation of appropriate preventive and curative measures in Africa is recognition of sickle cell disease as a priority in public health care policy.

Abstract
Type I spinal muscular atrophy or Werdnig-Hoffman disease is rarely described in black populations. We report five such cases diagnosed in a paediatric outpatient clinic in Dakar. We conducted a retrospective study relating to patients examined for hypotonia progressing since birth for whom the electromyogram had made it possible to confirm an involvement of the peripheral nerve without nerve conduction anomaly. Mean age of diagnosis was 12.3 +/- 7.6 months. Respiratory distress was noted for 2 patients. A family background of similar symptomatology was found in 1 case and consanguinity in 2 cases. Only 1 case of death occurred whereas the 4 other patients were lost to follow-up. The diagnosis of spinal muscular atrophy must be considered in the presence of any severe hypotonia in infants.

Abstract
Malignant hemopathies are not considered as public health priority in Senegal because of their infrequency in comparison with infections and malnutrition. However they remain usually lethal instead of a great improvement of their prognosis in suitable therapeutic conditions. The objective of this study was to determine the epidemiologic and evolutionnal profile of these pathologies, and identify practical management problems in a reference public pediatric service in Senegal. We retrospectively analysed hospitals registers and records of all patients followed up in Albert Royer Children Hospital of Dakar from january 1989 to december 1998. During this ten years period 25 cases of malignant hemopathies were diagnosed among 32,789 hospitalised children, representing an hospital prevalence of 0.08 per cent. Mean age at the desease diagnosis was 9.5 years and sex ratio 2.57 (18 boys and 7 girls). The malignant type was acute leukemia (AL) in 11 cases (44%) including 9 cases of of acute lymphoblastic leukemia (ALL) and 2 cases of acute myeloblastic leukemia (AML); chronic myeloid leukemia (CML) in 2 cases (8%), Hodgkin's desease (HD) in 9 cases (36%) and non hodgkinian lymphoma (NHL) in 3 cases. NHLwere Burkitt type in 2casesand lymphoblastic type in 1 case. Their was no maxillary or facial localisation in Burkitt type lymphoma. The mean duration between the first clinical symptomes and the diagnosis of the disease was 4 months and delayed diagnosis was mainly due to delayed transfer from peripheral health services to hospital. Among 19 patients whose records were available, 17 were subjected to chemotherapy. However reference protocols were completely applyed in only 2 cases, one with HD and an other with lymphoblastic lymphoma. Transfusion managementwas not sufficient because of the lack of blood derived products (packed platelets or leucocytes) when needed. Thirteen patients died while followed up and mean survival after first hospitalisation in these cases was 120 days in ALL, 38 days in AML, 2.5 years in HD and 18 months in NHL The other patients were lost of sight and presumed to be dead at home. Eventually, this study showed that, in our hospital, children with malignant hemopathies did not derive benefit of therapeutic progress enregistered long time ago in developed countries, since they remain constantly lethal. The main factors of lethality could be delayed transfer to hospital because of lack of knowledge about these pathologies in the peripheral health services and poor therapeutic conditions in reference hospitals. Creation of specialised clinical haematology department could enable us to improve the prognosis of these affections by an optimal use of available human and material ressources.

Abstract
This report is a retrospective study carried out from records of diseased of asthma, fallowed up in a paediatric national center of reference during the period from 1st of November 1987 to 31 st of august 1993. The goal was to describe the epidemiological and clinical factors linked to that affection in order to better contribute to improve its managment. For all the diseaseds of this report we notice and analysed the socio economical data, the promoting factors the occurring mode of the disease, the main clinical manifestations of the affection and their consequences. The morbid association and the data of the paraclinical exploration particularly the functional breathing exploration. Thus we noticed that the consultation in a specialized center occurs relatively late because of bad orientation of the deseaseds. In effect the mean age of diseaseds at the first consultation is 7.5 years while the disease begins in average at 3.5 years. By elsewhere we notice that 15% of these diseaseds live in an aggressive mesologic medium. With an atopy in 78.4% of the cases, loaded personal case history in 96.6% of the cases and that the releasing factors are not known for most of them (81.9%). Asthma in our diseaseds is not very frequent (77%) in general with a moderate intensity of crises (69%). However disturbances of physical activity are noted among 23% of the sample which corresponds nearly to the number of subjects with severe respiratory obstruction (25%). We quoted that there is an relation ship between the frequency of the cases the intensity of the crisis and the disturbances of physical activities of the diseaseds (x2:25.9, df = 2, p= 0,000002). Tacking count of all these factors may serve to set up a asthma prevention and treatment project in Senegal based on populations education and care providers training.

Abstract
Major thrombocytosis associated with severe anemia is uncommon in pediatrics. We report 9 consecutive cases observed in Albert Royer Children Hospital of Dakar. They were 7 boys and 2 girls 4 to 15 years old (mean age = 10 years). Six patients had a history of geophagia and 3 presented recent emission of worms by the stools. Anemia was clinically well tolerated in all cases. In initial blood count platelet levels varied from 800 10(3) to 1180 10(3)/mm3 (mean = 1032 10(3)/mm3), while hemoglobin level varied from 3.4 to 7.4 g/dl (mean = 4.9 g/dl). Anemia was microcytic, hypochromic and associated with low serum iron level in all patients. We considered the diagnosis of reactive thrombocytosis induced by iron deficient anemia in all cases. Platelet count and red cell indices were progressively normalised with iron treatment and no complication of thrombocytosis was observed. Considering published data, iron deficiency is one of the most frequent causes of reactive thrombocytosis in children. The physiopathologic mechanism, still unknown, could involve cytokines of thrombopoiesis. Reactive thrombocytosis induced by iron deficiency or other factors have usually a benign course and need no specific treatment other than that of the etiology.

Abstract
AIMS OF THE STUDY a) to identify the risk factors associated with newborn babies' low birth weight in teenage mothers; b) to propose prevention strategies for lower-ing neonatal morbidity and mortality. SPHERE OF THE STUDY: the study was carried out at the maternity and neonatology service of the Abass Ndao hospital centre, a urban community hospital located in the Southern part of Dakar. MATIERIAL AND METHODS: this retrospective study was carried out between July 1, 1998 and June 31, 1999. All new mothers under 20 who had given birth to living newborn babies have been included in the study and categorised into two groups, according to their babies' birth weight: 1) a first group of teenagers whose newborn babies' birth weight was lower than 2,500 g (low birth weight); 2) a second group constituted of women whose newborn babies' birth weight was higher than 2,500 g, and which was used as a control. The socio-demographic, biometrics, maternal and obstetric factors have been analysed and compared. RESULTS out of the 4,586 women in childbirth during the study period, 456 were under 20 years of age, which corresponds to a prevalence rate of 10%. One hundred and five women had newborns weighing less than 2,500 g, which corresponds to a prevalence rate of 23%. Certain factors were found to be significantly associated with low birth weight: low weight gain during pregnancy (p = 0.04), fewer antenatal consultations (0.006), and kidney-related syndromes during pregnancy (0.0005). CONCLUSION The results of that study allow us to recommend the following strategies: - control and improvement of nutritional behaviour during pregnancy; campaigning for a better attendance at antenatal consultation services for the early detection of pathologies during pregnancy and for preventing kidney-related syndromes.

Abstract
BACKGROUND Cardiovascular involvement is not well studied in children with sickle cell disease. The aim of this study was to evaluate the echocardiographic parameters of children with sickle cell disease. PATIENTS AND METHODS We performed a transversal and case-control study including 80 subjects of six months to 16 years of age divided into four groups of 20 children each: heterozygous sickle cell disease, homozygous sickle cell anemia, anemia of other causes than sickle cell, and healthy children. All children had a complete physical examination, biological screening including hemogram and hemoglobin electrophoresis, chest x-ray, electrocardiogram, and Doppler echocardiogram. Data were compared using the chi 2 method and the Student's t-test. RESULTS The mean age was 8.5 years and the sex-ratio was 1. Echocardiographic abnormalities were observed in seven patients with anemia unrelated to sickle cell, 15 children with heterozygous anemia and all the homozygous patients. The main abnormalities were: left ventricular enlargement (ten homozygous patients, one heterozygous subject, five of the patients with another cause of anemia), increased contractility of the heart (18 homozygous patients, seven heterozygous patients, five in the anemia group) and mild to moderate mitral or tricuspid regurgitation (12 homozygous, five heterozygous and five patients in the anemia group). One homozygous child had a dilated and hypokinetic cardiomyopathy with pulmonary hypertension. The parameters of left ventricular systolic function and left heart chamber dimensions were lower in the control group (P < 0.04). DISCUSSION This study shows the frequency of heart chamber dilatation with left ventricular hyperkinesis usually described in the literature. The lack of case of chronic cor pulmonale may be due to the young age of our patients. One case of dilated and hypokinetic cardiomyopathy suggests that other causes than anemia should be considered, particularly myocardial ischemia, which could not be demonstrated because of our limited investigative methods. CONCLUSION These results emphasize the frequency of the heart involvement in sickle cell disease, particularly in the homozygous type, and point out the importance of the cardiologic screening of these patients.

Abstract
The course of sickle cell disease (SCD) may be complicated by neurologic events, mainly bactérial meningitidis and stroke. We retrospectively studied all cases with acute encephalic manifestations (AEM) in a cohort of 461 children and adolescents with SCD followed at Albert Royer Children Hospital of Dakar (Senegal) from january 1991 to december 2000 (ten years). Among them 438 had sickle cell anemia (SCA), 19 SC disease and 4 S-beta thalassemia (3 S-beta+, 1 S-beta0). Seven patients, all with SCA, presented antecedents of AEM revealed by flacid and proportionnal hemiplegia evoking stroke. Prevalence of these AEM was 1.5 per cent among patients with SCD and 1.6 per cent among those with SCA. They were 4 girls and 3 boys (sex ratio = 0.75) aged 4 to 8.5 years when occurred the first accident. We observed no clinical or biological distinctive characteristic of SCA in these patients compared to those without crebrovascular accident. Recurrence was observed once in a boy after a 12 months interval and twice in a girl after 20 and 60 months intervals successively. No transfusionnal program was applied to prevent recurrent stroke because of insufficient conditions for long-term transfusion. Stroke appears to be rare in senegalese children with SCD. However it poses in our context the major problem of applicability of transfusionnal program which constitute the only therapy universally recognised to be effective to prevent recurrence. Nevertheless hydroxyurea could be a satisfactory alternative.

Abstract
The authors report the results of a retrospective study on the effect of traumatic injuries observed among newborns from forceps deliveries in the maternity ward of Abass Ndao hospital between January 1st, 1995 and December 31, 1996. Forceps deliveries represent 5.89 for 1000 of total deliveries and 47 for 1000 of nursery admissions. Traumatic injuries are found in 44.77 % of the newborn by forceps deliveries. They are dominated by the hematoma of scalp in 23 cases and facial nerve injuries in 6 cases. The were about 76.66 percent of primipare among which 30 percent were adolescents. Maternal age, parity, gravity as well as birth weight for forceps deliveries were not significantly different from those without any injuries (p < 0.05). However, traumatic injuries of the newborn were more frequent when the forceps were performed by medical resident. The neonatal mortality is 10.44%. We recommend the teaching of the technique for an improvement of technical competence.

Abstract
Rubella is an innocuous illness in adult unless it is contracted by a pregnant woman. We recently observed a case of congenital rubella in the department of neonatology of Abass Ndao hospital in Dakar. It's a female new-born, born after 40 week gestation, with a well followed pregnancy. The first clinical examination shows a severe intrauterine growth retardation and bilateral comeal opacity. Maternal and new-born serologic confirmation is obtained with positive rubella specific IgM and IgG. We also find severe ocular pathology, hearing deficit and associated cardiac disease. This case shows the needs for preventive strategies, such as vaccination against rubella for women of child bearing age.

Abstract
Hemolytic uremic syndrome (HUS) is an nonexceptional complication of infectious gastroenteritis. No one has already been reported in Senegalese publications. We made a retrospective study of the record of 7 patients with HUS among 256 cases of children with bloody diarrhea presenting to the pediatric unit of Aristide Le Dantec between august 1998 and july 1999. The mean age of the children was 33,14+/-25 months and the weight was -2,29 DS. The diagnosis is supported by the findings of an acute renal failure with urea at 1,28+/-0,51g/ l and creatinine at 41,46+/-25,48mg/l. An hemolytic anemia was constant, the blood film revealed schizocytes. We found a thrombocytemia only in two cases. A hight white blood cell count (more than 50000/mm3) was noted in for cases. Only one child made a good recovery. We insist on preventing gastroenteritis and aggressive and adapted management of the HUS.

Abstract
A retrospective study carried on between april 1st and september 31st 1997 has helped in collecting. 69 cases of low birth weight new-born (weight < 2500 g) at Abass Ndao hospital center in Dakar. The above population has been compared to 79 eutrophic new-born of mean birth weight equal to 3047.7 +/- 311 g (witnesses). The goal of this study is to appreciate the relationship between the maternal age, the number of the gestation, the parity, the nutritional status, the maternal pathologies during pregnancy and the low weight at birth. There was no difference between both groups as regards to the mean age (p = 0.44), the mean number of gestation (p = 0.7) and the mean parity (p = 0.48). On the other hand, the weight of the mother is smaller as for the group of low birth weight but the mean body mass index stand at normal in both groups. The pathologies during pregnancy period were obviously more frequent in the group of low birth weight new-born. There is a real need to insist on the preventive measures to be taken and the treatment of the maternal pathologies during pregnancy.
