Noma is an opportunistic infection promoted by extreme poverty. It evolves rapidly from a gingival inflammation to grotesque orofacial gangrene. It occurs worldwide, but is most common in sub-Saharan Africa. The peak incidence of acute noma is at ages 1-4 years, coinciding with the period of linear growth retardation in deprived children. Noma is a scourge in communities with poor environmental sanitation. It results from complex interactions between malnutrition, infections, and compromised immunity. Diseases that commonly precede noma include measles, malaria, severe diarrhoea, and necrotising ulcerative gingivitis. The acute stage responds readily to antibiotic treatment. The sequelae after healing include variable functional and aesthetic impairments, which require reconstructive surgery. Noma can be prevented through promotion of national awareness of the disease, poverty reduction, improved nutrition, promotion of exclusive breastfeeding in the first 3-6 months of life, optimum prenatal care, and timely immunisations against the common childhood diseases.

The cancrum oris is still an up to date disease in our environment. The death rate and the after effects of this disease make all together the main interest of this survey. In a retrospective survey carried out from January 2003 to December 2012, we colligated 55 cases of progressive cancrum oris followed at the stomatological and maxillofacial surgery at the Academic Hospital Yalgado OUEDRAOGO. On the epidemiological level, we noticed an impact of 5.5 cases per year. The average age of our patients was about 7.64 with a sex ratio of 1.03. Most of the patients were from an underprivileged family (96.4%). On the clinical level, we noticed that most of the patients consulted only after the gangrene had fallen (89.1%) and were seriously affected (67.3%) with a bad oral and dental hygiene (38.1%). The attacks were mainly jugal (25%) and labial (24.1%). The cancrum oris was in most of the cases associated to broncho pneumonitis, malaria and to HIV infection (31.37%). For the medical treatment, we focused on resuscitation, re nutrition, hydro electrolytic rebalancing and antibiotherapy. The surgical treatment was essentially made on the affected areas, controlled skinning and most often followed by sequestrectomy. 81.8% of the patients recovered completely from the infection, 60% had after effect injuries. We recorded a death rate of 14.5%. In order to overcome this disease we need both national and international support.

Cancrum oris is a gangrenous stomatitis arising from a periodontal infection and leading to severe soft tissue and bone destruction. The pathology involves numerous factors including local thrombosis, vascularitis, necrotizing gingivitis, immunodeficiency, Gram negative and anaerobic infection. It is usually a disease of infants and malnourished children in tropical areas often occurring after a debilitating disease like measles [3]. Burkitt lymphoma is a highly aggressive non-Hodgkin lymphoma first described by Burkitt in 1958 in African children from areas holoendemic for malaria. It is the first cancer of African child [6]. The association between Burkitt lymphoma and cancrum oris is non common. We report in the present study three cases of this association at the Academic Hospital Yalgado Ouedraogo of Ouagadougou. This association poses a problem of late diagnosis with difficulties in therapeutic management.

Noma is an orofacial gangrene affecting malnourished children and mainly observed in tropical countries, particularly sub-Saharan Africa. Epidemiological data on noma are scarce, but a current estimate of the global incidence is 30,000-40,000 cases per year, with a mortality rate of approximately 85% and a burden of disease calculated to be a loss of 1-10 million disability-adjusted life years. The etiology of noma is multifactorial with malnutrition as an ever present factor, often in combination with concomitant diseases, such as measles, malaria, and human immunodeficiency virus (HIV), and poor oral hygiene. The pathogenesis is a fast-spreading, noncontagious gangrenous infection occurring in the face, often preceded by acute necrotizing gingivitis, and stomatitis. Rare microbiological studies suggest an opportunistic infection caused by an imbalance in normal intraoral microorganisms. Prevention lies in food security, measles vaccination, prevention of malaria and HIV, including the early detection and treatment of necrotizing gingivitis and stomatitis. Early treatment with antibiotics may prevent gangrene or reduce its extent. Late treatment consists of surgical rehabilitation, which is often complex. However, access to medical care is very limited for noma patients due to the extremely poor conditions in which they live that are frequently located in remote rural areas. The authors support the United Nations Human Rights Council Resolution 19/7 adopted on March 22, 2012 "The right to food," and advocate for the inclusion of noma on the list of neglected tropical diseases to encourage more medical and institutional attention for this often lethal or very mutilating infectious gangrene.

Noma (canrum oris) is a mutilating necrotizing disease of uncertain etiology, but it is accepted that it is caused primarily by a polybacterial infection with secondary ischemia. The consequent necrotizing fasciitis, myonecrosis, and osteonecrosis results in destruction of facial structures with severe functional impairment and disfigurement. It most frequently affects children, particularly in sub-Saharan Africa, who are malnourished or debilitated by systemic conditions including but not limited to malaria, measles, and tuberculosis; and less frequently debilitated HIV-seropositive subjects. In the vast majority of cases, in susceptible subjects, noma is preceded by necrotizing stomatitis. However, it has been reported, albeit rarely, that noma can arise without any preceding oral lesions being observed. Noma is not recurrent and is not transmissible.
