Surgical Procedures, Complications, and Durations in Patients with Noma Disease: A Cross-sectional Study

Background

Noma is a devastating disease that causes severe destruction of facial tissue, necessitating comprehensive surgical intervention for functional restoration and improved quality of life. This cross-sectional study aimed to identify common surgical procedures used for noma defect reconstruction in Ethiopia, analyze their durations, and assess associated complications.

Methods

The study retrospectively analyzed noma patient records from Facing Africa's database, covering electronic medical data from 2007 to 2019, and utilized SPSS version 2020 for analysis.

Results

Facing Africa treated 235 noma cases (2007-2019) with 438 procedures. The most commonly used surgical technique was reconstructive surgery, which encompassed two or more other surgical methods and was used in 177 cases. This was followed by the submental flap in 47 cases and ankylosis release in 35 cases. The study also found complications in 11 cases, including flap necrosis, abscesses, and ankylosis-related mouth restriction. Additionally, the analysis of 102 noma cases revealed significant variations in the duration of surgical procedures, ranging from 10 to 48 hours for specific cases, with the majority (63.7%) requiring 2 to 5 hours. The mean duration of noma surgery was calculated to be 4.08 hours.

Conclusions

Comprehending common surgical techniques, complications, and durations benefits surgical planning, resource allocation, and patient care. Thus, the results of this study are a useful contribution to the development of effective noma treatment. However, further research and continuous efforts are needed to refine surgical practices, address potential complications, and enhance patient care in the battle against this devastating disease.

Protocol for a systematic review of the evidence-based knowledge on the distribution, associated risk factors, the prevention and treatment modalities for noma

Introduction: Noma (cancrum oris) is a devastating opportunistic infection resulting in severe tissue destruction that affects mouth and oro-facial structures. There are substantial gaps in our current knowledge and understanding of its aetiology, pathogenesis, prevention and treatment efficacy, as well as its distribution and burden. Although observed worldwide, the disease impacts the most vulnerable and marginalised populations, and is most reported in young children from sub-Saharan Africa. Noma often presents alongside conditions of extreme poverty, malnutrition and poor environmental sanitation. This protocol paper outlines the methodology for a systematic review planned to exhaustively synthesize the findings of the available noma literature. The project aims to generate an account of the present state of knowledge about the various aspects of noma to aid in framing effective strategies and interventions to curb this disease which disproportionately afflicts the poorest in society. Methods and analysis: The following databases have been searched by a medical librarian from database inception to 7 December 2022: OVID (MEDLINE/ Embase/ CAB abstracts/ Global Health), Scopus, Web of Science, African Index Medicus, African Journals Online: Health, French language search: Pascal, ClinicalTrials.gov, and WHO ICTRP. All primary research studies reporting on patients of any age diagnosed with noma will be eligible for inclusion in the review, including clinical trials, cohort studies, case-control, cross-sectional, other observational studies, case studies and case series. Data will be extracted from included studies to analyse the current evidence-based knowledge on the distribution, risk factors, microbiology, prevention and treatment modalities, and outcomes of noma. Ethics and dissemination: Results of this systematic review will be published in a peer-reviewed journal upon completion. PROSPERO Registration: CRD42019124839 (08/03/2019)

Facing Africa: Describing Noma in Ethiopia

Noma affects the most marginalized communities in the world, beginning as oral ulceration and rapidly progressing to orofacial gangrene. With a mortality rate estimated to be as high as 90% and with very few able to access treatment in its active phase, very little is understood about the disease. This retrospective review of patients treated by Facing Africa for deformity and functional impairment secondary to noma between May 2015 and 2019 highlights some of the difficulties encountered by those afflicted. Eighty new patients with historical noma defects were identified and were seen over the course of nine surgical missions, with notes providing valuable geographical, socioeconomic, and psychosocial information. The mean self-reported age of onset was 5 years and 8 months, with a median time of 18 years from onset to accessing treatment. Before intervention, 65% covered their face in public, 59% reported difficulty eating, 81% were unhappy with their appearance, and 71% experienced bullying. We aimed at emphasizing the significant burden, both psychologically and physically of noma, demonstrating the disparity between recent decades of progress in the well-being of Ethiopians in general and the access to health care and mental health support for some of those most in need.
