Management of neural tube defects in a Sub-Saharan African country: the situation in Yaounde, Cameroon.

BACKGROUND: Neural tube defect is a serious disabling but preventable congenital malformation with an incidence of 1.99 per 1000 births in Yaounde [A.K. Njamnshi, V. d e P. Djientcheu, A. Lekoubou, M. Guemse, M.T. Obama, R. Mbu, S. Takongmo, I. Kago. Neural tube defects are rare among black Americans but not in Sub-Saharan black Africans: The case of Yaounde-Cameroon. Journal of the Neurological Sciences 2008; 270: 13-17]. The management requires highly qualified personnel and a significant social cost. The aim of this study was to evaluate the management of neural tube defect in a resource-limited developing Sub-Saharan nation like Cameroon. METHODS: We reviewed all patients with neural tube defects admitted in the neonatology unit of the Mother and Child Center (Chantal Biya Foundation Yaounde) between January 1st 2000 and December 31st 2006. RESULTS: Sixty-nine (69) patients were enrolled. There was a male predominance (69.57%) in the sample. Myelomeningomecele represented 68.11% of cases, followed by encephalocele (27.54%) and meningocele (4.35%). Antenatal ultrasound examinations were done in 27 cases (32.8%). The prenatal diagnosis was made only in 8 cases. No medical abortion was performed in any of these cases. Medical abortion is illegal in Cameroon (except in certain specific situations) as well as other Sub-Saharan African countries. Hydrocephalus was diagnosed in 40.02% of cases. As most of the patients (62.32%) could not afford modern treatment, only 26.09% of them were operated at birth. The rest sought traditional and other forms of treatment, due to poverty or cultural beliefs. Eight patients (11.59%) died before surgery. Surgery consisted of local closure alone (40%) or local closure associated to CSF shunting (60%). The complications were wound dehiscence (13.69%), shunt infection (1.37%), meningitis (1.37%) and iatrogenic pulmonary oedema (1.37%). CONCLUSION: Neural tube defects are the most frequent and disabling malformations in neonates in the Sub-Saharan African paediatric environment. Prenatal management and outcome at birth are limited by poverty and cultural beliefs. Prevention is possible and may be better than palliative care in developing countries.

[Clinical and bacteriological profile of neonatal bacterial infection at Laquintinie Hospital, Douala (Cameroon)]. / Profil clinique et bactériologique des infections néonatales bactériennes à l'Hôpital Laquintinie de Douala, Cameroun.

INTRODUCTION: The World Health Organization has estimated that the global incidence of neonatal deaths was 2,8 million in 2015, of which 47,6% were due to infections. These infections can affect newborns babies ages 0-1 month through 3 months. METHODS: This is a prospective study conducted from 1 March to 30 June 2015 in the Neonatology service of the Laquintinie Hospital at Douala. All symptomatic newborns with or without anamnestic criteria and all asymptomatic newborns, with at least an infectious risk and a positive blood culture or an abnormal blood count or positive C-reactive protein were included in the study. RESULTS: Of the 310 newborns enrolled in the study, 300 were retained for neonatal infection, corresponding to a total incidence of 96.8%. We performed 104 cultures, of which 25 were positive, corresponding to an incidence of confirmed neonatal infection of 24%. The factors associated with infection were unexplained preterm birth < 35 weeks of amenorrhea (45,1%) and neonatal resuscitation (34,8%). Fever (56%) and neurological disorders (48.8%) were the most frequent clinical symptoms. Gram-negative bacteria were the most frequent germs (56%). Imipenem (95%) and amikacin (66.7%) were the most effective antibiotics. Outcome was favorable in 66,4% of cases and the overall mortality rate was 33,6%. CONCLUSION: This study revealed a high prevalence of neonatal bacterial infection in this Hospital. Bacterial ecology was dominated by Gram-negative bacteria. It was recorded a significant resistance to the most widely used antibiotics and a fairly high mortality.

Competence of health care providers on care of newborns at birth in a level-1 health facility in Yaoundé, Cameroon.

INTRODUCTION: This is an observational study which was carried out at a level one health facility in Yaoundé from June to July 2009. The aim was to evaluate the competence of health care providers towards newborns' care at birth METHODS: Ten health care providers took care of three hundred and thirty-five pregnant women who were enrolled for the study after informed verbal consent in the delivery room. RESULTS: Out of 340 offspring delivered and taken care of, 179 (52.6%) were male and 161 (47.4%) were female. Only two out of ten health workers had a WHO Essential Newborn Care (ENC) training. None of them had received any refresher course for the past two years. The mean gestational age of women was 39.5 ± 3.5 weeks. Resuscitation was carried out on 21 (6.2%) of the newborns including 7 (33.3%) who had birth asphyxia. Health care providers scored 100% in performing the following tasks: warming up the baby, applying eye drops, injecting vitamin K, identifying the neonate, searching for any apparent life threatening congenital malformations, preventing for infection after procedures and initiating breastfeeding. The score was 24% at neonatal resuscitation tasks. Low level of education was associated with poor competence on applying ENC tasks (p<0.001). Lack of WHO ENC training was associated with poor competence on ENC tasks (p<0.001) and poor skills on resuscitation (p=0.03). CONCLUSION: There is a need to reinforce the capacity of health care providers by training in WHO ENC course with emphasis on providing skills on resuscitation in order to reduce the burden of neonatal intrapartum-related deaths.
