Facing Africa: Describing Noma in Ethiopia

Implementation and Evaluation of a Training Program for Traditional Healers to Improve Knowledge of Noma (Cancrum Oris) in Burkina Faso

Noma (cancrum oris) is an orofacial gangrene affecting young children living in extreme poverty. The acute morbidity is high, and survivors suffer from physical and social sequelae. When diagnosed early, noma can be cured. Noma is especially prevalent in sub-Saharan Africa, where traditional medicine is the norm. The aim of this work was to provide 1-day training to traditional healers in Burkina Faso and to evaluate change in knowledge of noma across time. A sample of 78 healers who attended the training were asked to complete the same questionnaire before, immediately after, and 8 months after the training. A total of 66 healers completed the entire study. Before training, more than 40% of the participants did not know any of its key messages. Most of the key messages were acquired and still present after 8 months by a large proportion of the participants. Systematic intraoral examination was practiced by 7 (9.0%) of the traditional healers before training, and 43 (65.2%) reported doing so 8 months after training. The key messages aiming to improve early diagnosis as well as rapid and adequate treatment (the recognition of facilitating factors and the need to perform a systematic oral examination and to advise hospital transfer) have been well integrated. The study suggests that organizing a self-managed training program is feasible when done within an association, as was the case here, and owing to the willingness to collaborate shown by the traditional healers who participated in our study.

Psychosocial aspects of Noma (Cancrum Oris) in sub-Saharan Africa: A scoping review

Noma is a neglected tropical disease of an underserved population. Our review describes the volume and scope of existing research evidence on psychosocial aspects of Noma in sub-Saharan Africa (SSA). Our literature search was conducted on all original peer-reviewed research articles on the psychosocial aspects of Noma in each country in SSA using PubMed, Google Scholar, and a direct search of reference list of pertinent journal articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines was used to describe the review. A total of six studies were found in four countries of the region. One in three persons with Noma has a mental health condition, indices of social disadvantage and belief in the supernatural causation of the disease are very common. However, despite evidence of enormous need, a huge gap still exists in the area of psychosocial alleviation.

The importance of a local cleft mission and its spread

OBJECTIVES

Cleft lip or palate are very usual birth defects. This study aims to discuss a local cleft mission performed in Angola and some specifics on the topic.

METHODS

This retrospective study assessed the main features of a local cleft mission conducted in September 2022. The mission was carried out at the Hospital Josina Machel in Luanda, Angola. Data was retrieved and analyzed. The Shapiro-Wilkes test and Pearson correlation were used and considered significant only at 95% confidence interval.

RESULTS

Cleft missions are a difficult task. Logistical and financial problems are exacerbated by the extreme difficulty of recruiting patients, particularly in remote regions, far from major centers. Despite successful widespread, some surgeries have been postponed due to comorbidities, common in Africa.

CONCLUSION

The organizers of the mission must be aware of the difficulty of attracting patients and must use different media such as television and radio. The internet needs to be used to the maximum and could reach a higher number of prospects.

Health-related quality of life in patients with noma (cancrum oris): Case series

INTRODUCTION AND IMPORTANCE

Cancrum oris (noma) is a destructive disease of orofacial tissues and adjacent structures that progress rapidly, causing functional and cosmetic problems to the patient and ultimately affecting their health-related quality of life. This case series focuses on the impact of the cancrum oris on the health-related quality of life of patients which has been underreported in literature.

CASE PRESENTATION

Herein, we present 3 cases (1 pediatric and 2 adult patients) of cancrum oris. One adult male succumbed to the disease while the remaining two are undergoing treatment. We used the modified versions of the Early Childhood Oral Health Impact Scale (ECOHIS) and the University of Washington-Quality of Life (UWQoL) questionnaire for pediatric and adult patients respectively.

CLINICAL DISCUSSION

The sequela of cancrum oris affects negatively the quality of life of the patients even after definitive management. Despite this, there is no validated questionnaire to assess the quality of life. The modified versions of the ECOHIS and the UWQoL questionnaires that were used in this case report can be used effectively to assess the HRQoL of the patients.

CONCLUSION

Cancrum oris is a neglected disease that affects negatively the health-related quality of life of patients who suffer from it, despite medical intervention.

Noma, a neglected disease: prevention is better than cure

PURPOSE OF REVIEW

There is a need for concerted effort to increase Global awareness about noma (cancrum oris). This paper aims to summarize the recent literature on noma and provide suggestions that could be implemented to raise awareness about this neglected disease.

RECENT FINDINGS

Noma has been recognized, diagnosed and reported for centuries. Despite significant progress in scientific methods over time, the published literature on noma has predominantly been of low level clinical and scientific evidence. Recent studies have reported on noma's global distribution and its predisposing risk factors, its treatment, its knowledge and beliefs and has included a number of literature reviews. Noma cases are being reported from an increasingly diverse set of geographical locations.

SUMMARY

Noma has largely been neglected in the research sphere. Noma is a preventable disease and its progression can be halted if patients are recognized and treated in the early stages of disease. Treatment for late stage noma survivors remains complex and time consuming, requiring substantial human and financial resources most commonly not achieving functional and cosmetic anatomy. The ultimate aim is therefore prevention, initiatives should be integrated into existing health programs.

Noma – a neglected disease of malnutrition and poor oral hygiene: A mini-review

Objectives:

The aim of this review was to describe malnutrition and poor oral hygiene, the most common risk factors for noma.

Methods:

A vigorous literature searches were conducted on databases such as Scopus, Elsevier, Web of Science, PubMed, Virtual Health Library, and Google Scholar by inserting keywords such as ‘noma’ OR ‘cancrum oris’ OR ‘cancrum oris cases’. A total of 65 articles gathered. Of these, 38 articles found to be eligible for this study.

Results:

A total of 38 full-length articles were included in the review. According to the evidence gathered and summarized in this review, malnutrition, especially protein-energy malnutrition and vitamin deficiencies, makes the oral mucosa susceptible to opportunistic pathogens of noma, and then, in so doing, pathogens invade the oral cavities. Malnutrition has a bidirectional relationship with noma. Since noma is a disease of the oral cavity, poor oral hygiene has the potential of predispose and worsen the disease’s progress.

Conclusion:

Malnutrition and poor oral hygiene found to be ingrained in the pathogenesis of noma. For effective management and prevention of noma, it is necessary to underpin adequate nutritional supplementation (including vitamins). As a primary prevention strategy, healthcare workers’ training should be strengthened to improve the diagnosis and treatment of oral infections, including noma.

Noma (cancrum oris): A scoping literature review of a neglected disease (1843 to 2021)

Background

Noma (cancrum oris) is an ancient but neglected and poorly understood preventable disease, afflicting the most disenfranchised populations in the world. It is a devastating and often fatal condition that requires urgent and intensive clinical and surgical care, often difficult to access as most cases of noma occur in resource-limited settings. We conducted a scoping review of the literature published on noma to understand the size and scope of available research on the disease and identify research gaps that need to be addressed to evolve our understanding of how to address this disease.

Methods

We searched 11 databases and collected primary peer reviewed articles on noma in all languages, the final search was conducted on 24^th August 2021. The oldest manuscript identified was from 28^th March 1843 and the most recently published manuscript was from 3^rd June 2021. Search terms included cancrum oris and noma. Data was extracted using a standardised data extraction tool and key areas of interest were identified. The Preferred Reporting Items for Systemic review and Meta-Analyses requirements were followed.

Results

The review included 147 articles, the majority of the studies (n = 94, 64%) were case reports. Most manuscripts (n = 81, 55%) were published in the 2000s, 49 (33%) were from the 1900s and 17 (12%) from the 1800s. The main areas of interest identified were the history and epidemiology of the disease, noma’s clinical progression and aetiology, treatment regimens, mortality rates and the risk factors for the development of noma.

Conclusions

Noma has been reported in the literature for hundreds of years; however important gaps in our understanding of the disease remain. Future research should focus on determining the burden and distribution of disease; the true mortality rate, pathogenic cause(s) and the factors that influence prognosis and outcomes after treatment.

Noma is a devastating and often fatal condition that mainly affects children in severely disenfranchised communities. Noma is preventable and requires urgent basic medical care in the early stages of disease. Once the disease reaches the last stage, sequelae, survivors require expert surgical care, usually difficult to access as most cases of noma occur in resource-limited settings. We conducted a scoping review of the literature published on noma to understand the size and scope of available research on the disease and to identify research priorities that will evolve our understanding of how to eradicate this disease. Our review showed that noma has been reported in the literature for hundreds of years; however several major gaps in knowledge still exist. There is appreciation among the small community of clinicians and researchers involved in noma care and research that these gaps in knowledge impact on the ability to develop and implement sound evidence-based policies and activities aimed at eradicating noma from communities that continue to be afflicted by this ancient disease. The main focus of future research should be to study the burden and distribution of disease; the true mortality rate, and the pathogenic cause(s) and the factors that influence prognosis and outcomes after treatment.

Noma and Necrotizing Fasciitis of the Face and Neck

Necrotizing fasciitis (NF) is part of the class of necrotizing soft tissue infections characterized by rapid fascial spread and necrosis of the skin, subcutaneous tissue, and superficial fascia. If left untreated, NF can rapidly deteriorate into multiorgan shock and systemic failure. NF most commonly infects the trunk and lower extremities, although it can sometimes present in the head and neck region. This review provides an overview of NF as it relates specifically to the head and neck region, including its associated clinical features and options for treatment. Noma, a related but relatively unknown disease, is then described along with its relationship with severe poverty.
