Abstract

in English, French

Background:

Noma (cancrum oris) remains the scourge of children and the "face of poverty" in Sub-Saharan Africa. Recent data on the burden of noma and its risk factors are needed for evaluating and redesigning interventions for its prevention and control.

Objectives:

This study aimed to determine the pattern of noma and its risk factors in Northwestern Nigeria.

Materials and Methods:

It was a retrospective study that looked into cases of noma (cancrum oris) admitted into the Noma Children Hospital, Sokoto, Nigeria, between January 1999 and December 2011. Information on patients' bio-data, the site and severity of lesions, and presence of trismus and its severity were extracted from the patients' case files and analyzed using descriptive statistics.

Results:

One hundred and fifty-nine (8.3%) of the 1923 patients admitted to the hospital from January 1999 to December 2011 were diagnosed with fresh noma. The mean age of the patients was 3.0 ± 1.4 years, and majority of them, 139 (87.4%) were aged 1-5 years. The soft-tissue lesions essentially involved multiple sites but most commonly the outer and inner cheeks (84.3%). The most common risk factors identified were measles (47.2%) and protein-energy malnutrition (42.1%). There were rises and falls in the prevalence of noma in the period studied.

Conclusion:

This study showed a high burden of noma in Northwestern Nigeria, mostly among children aged 1-5 years, and with soft-tissue lesions involving multiple sites. Measles and malnutrition were the major risk factors identified, and the disease trend showed a wave-like pattern. There is an urgent need to eliminate the disease in Nigeria through prevention and control of infectious diseases and malnutrition.
