A history of noma, the "Face of Poverty"

High burden of noma in the Gambella region of Ethiopia: a 12-year retrospective study on noma cases from the Facing Africa database

BACKGROUND

Noma, an infectious disease, mainly affects impoverished children. This study retrospectively assessed noma's prevalence in Ethiopia using data from the Facing Africa database and the 2022 United Nations Development Programme poverty index report.

METHODS

A thorough review of medical records spanning 2007 to 2019 identified a total of 235 noma cases. A standardized data extraction template was employed to systematically gather pertinent clinical and demographic data for subsequent analysis. Prevalence rates were calculated nationally and regionally for both the general population and children aged ≤10 y.

RESULTS

The analysis revealed estimated national prevalence rates of 0.65 per 100 000 individuals at risk and 1.9 per 100 000 children aged <10 y at risk. The Gambela region exhibited the highest prevalence rate (11.2 per 100 000), whereas the Benshangul Gumuz region had the lowest (0.25 per 100 000). Similar patterns were observed among children aged ≤10 y, with the Gambela and Benshangul Gumuz regions reporting rates of 32.9 and 0.74 per 100 000, respectively.

CONCLUSIONS

The study highlights noma's significant impact on children aged <10 y in Ethiopia, especially in the Gambella region. It offers crucial baseline data to assist public health professionals, policymakers and healthcare providers in formulating evidence-based strategies to combat noma and improve affected individuals' well-being.

A noma case report: A warning message from Northern Uganda

Noma, or Cancrum oris, is a severe and rapidly progressing gangrenous infection that primarily affects the face. It is most commonly observed in children living in impoverished conditions, especially in sub-Saharan Africa. Rapid diagnosis and early management are crucial to prevent devastating consequences, such as functional limitations and serious psychological repercussions. Herein, we present a case of an 8-month-old child affected by noma, whose positive outcome is attributed to the prompt recognition by healthcare personnel. In our patient, the condition was likely related to malnutrition and the preceding extraction of a deciduous tooth reported by the mother and probably associated with a traditional Ugandan practice called Ebiino. This is the second case reported in Uganda, and given the limited healthcare access in most of the country, coupled with the high prevalence of poverty and other predisposing factors, it becomes evident that the incidence of noma is underestimated. Noma, as a neglected disease, requires greater awareness within communities and among healthcare professionals. A collective effort is needed to significantly reduce risk factors and promote prevention of this life-threatening disease.

Noma in the WHO's list of neglected tropical diseases: A review of its impact on undeveloped and developing tropical regions

Background

Noma is a neglected tropical disease and a global health concern.

Objectives

To elucidate the epidemiology, management, prevention, and public health implications of Noma.

Methods

PubMed, Scopus, and Web of Science, supplemented by Google Scholar and World Health Organization databases, were searched using keywords to gather both published and grey literature from 1970 to 2023 in English.

Results

Approximately 30,000-40,000 cases occur annually, with varying incidences across various African countries, such as Nigeria, Niger, and Chad. Incidence in Nigerian and Ethiopian states range from 0.6 to 3300 and 1.64 to 13.4 per 100,000 population, respectively. Mortality is approximately 8.5% in Niger. Risk factors include malnutrition, immunocompromised status, poor dental hygiene, inadequate sanitation, gingival lesions, low socioeconomic status, chronic and infectious diseases, low birth weight, high parity, diarrhoea, and fever. Diagnosis is primarily made based on clinical signs/symptoms and accordingly staging of disease is done. Stage I, II and II presents with acute necrotizing gingivitis, facial edema with halitosis, and necrotizing stomatitis, respectively. If the patient survives acute stages, the progress to Stage IV and Stage V manifests as trismus, difficulty in deglutition and phonation, and facial disfigurement, with increased severity in last stage. Treatment encompasses antibiotic therapy (amoxicillin, metronidazole, chlorhexidine, ampicillin, gentamicin), surgical interventions, wound management (honey dressing, ketamine), and nutritional support. Prevention strategies include oral hygiene, vaccination, health education, and community-based interventions.

Conclusion

Noma's recent inclusion in WHO list of neglected tropical diseases is a milestone in recognizing the importance of prevention and early intervention to globally enhance health outcomes.

Prevalence and associated risk factors for noma in Nigerian children: a systematic review and meta-analysis

OBJECTIVES

To determine the prevalence, case-fatality rate, and associated risk-factors of Noma in children in Nigeria.

METHODS

Search was conducted in PubMed, Google Scholar, and Cochrane Library databases. Data were extraction using a double-blind approach. Discrepancies were resolved by a third reviewer. Heterogeneity was evaluated using I2 statistics. Random-effects model was used for the meta-analysis and subgroup analysis was conducted. The study quality was evaluated using standard Critical-Appraisal-Checklist.

RESULTS

Of the 1652 articles identified, 12 studies that met the inclusion criteria included 871 cases of Noma. Two studies had high-risk of bias and were excluded in the meta-analysis. Pooled prevalence of Noma was 2.95% (95%CI:2.19-3.71; Z = 7.60; p < 0.00001, I2:100.0). Case fatality was reported in one study. Sex-distribution had a male-to-female ratio of 1.1:1. Malnutrition (88.42%, 95%CI:52.84-124.00; I2:100.0), measles (40.60%; 95% CI:31.56-49.65; I2:100.0) and malaria (30.75%; 95% CI:30.06-31.45; I2:100.0) were the most notable associated risk-factors. Prevalence of Noma was non-significantly lower in southern (1.96%,95%CI:1.49-2.44;6 studies) than in northern (4.43%; 95%CI:-0.98-9.83; 4 studies) Nigeria. One study reported the prevalence of Noma in children younger than 5 years.

CONCLUSIONS

About every 3 in 100 children in Nigeria had Noma and the prevalence was non-significantly higher in northern than southern Nigeria. Malnutrition, measles, and malaria were major associated risk-factors. Case-fatality rate and prevalence based on different age-groups were inconclusive.

Noma finally recognised as a neglected tropical disease

In December 2023, after decades of tireless advocacy from stakeholders and partners, the World Health Organization (WHO) gave noma the long overdue recognition as a neglected tropical disease. The significance of this official recognition cannot be overstated, and it is hoped this will serve as a turning point in our battle against this devastating disease.

Surgical complications and subsequent revision surgeries among noma cases treated in Ethiopia

Introduction

Noma, an overlooked infectious disease, inflicts severe facial tissue damage, posing substantial challenges in patient care. This study delves into surgical complications and subsequent revision surgeries among noma cases treated in Ethiopia.

Materials and Methods

The research employed a cross-sectional retrospective review of medical records treated between 2007 and 2019 retrieved from the Facing Africa database.

Results

The review encompasses 235 noma cases. Twenty-four cases (19 females and 5 males) experienced various complications, predominately major complications leading to subsequent revision surgeries. The identified complications included flap necrosis, abscess formation, tenderness, graft site infection, flap bulking, dental misalignment, corner of the mouth dehiscence, infected bone and plate, flap malpositioning, restricted mouth opening with ankylosis, neuropathic pain, recurrent flap infection, and offensive odor. Revision surgeries included wound cleansing, abscess drainage, skin graft removal, exploratory surgery, wound care, debulking, scar removal, debridement, trismus release, commisuroplasty, and flap repositioning.

Conclusion

These findings illuminate the intricacies of noma surgery in Ethiopia, emphasizing the importance of understanding the nature and frequency of complications for optimizing treatment outcomes. Insights from this study can guide healthcare providers, especially novice surgeons, and policymakers, in refining surgical interventions and enhancing outcomes for noma patients. Improved knowledge in this realm is crucial for advancing patient care and developing targeted interventions.

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.

A retrospective clinical, multi-center cross-sectional study to assess the severity and sequela of Noma/Cancrum oris in Ethiopia

Introduction

Noma is a disfiguring gangrenous disease of the orofacial tissue and predominantly affects malnourished children. The tissue gangrene or necrosis starts in the mouth and eventually spreads intra-orally with the destruction of soft and hard tissues. If not controlled, the natural course of the condition leads to a perforation through the skin of the face, creating a severe cosmetic and functional defect, which often affects the mid-facial structures. Furthermore, the course of the disease is fulminating, and without timely intervention, it is fatal.

Materials and methods

A retrospective clinical cross-sectional study was conducted to assess the sequela and severity of Noma in Ethiopia. Medical records of patients diagnosed with Noma were reviewed. The medical files were obtained from Yekatik 12 Hospital, Facing Africa, and the Harar project,—the three major Noma treatment centers in Ethiopia. The severity of facial tissue damage and the extent of mouth trismus (ankylosis) were examined based on the NOIPTUS score.

Results

A total of 163 medical records were reviewed. Of those, 52% (n = 85) and 48% (n = 78) have reported left-sided and right-sided facial defects, respectively. The facial defects ranged from minor to severe tissue damage. In other words, 42.3% (n = 69), 30.7% (n = 50), 19% (n = 31), and 8% (n = 13) have reported Grade-2 (25–50%), Grade-3 (50–75%), Grade-1 (0–25%), and Grade-4 (75–100%) tissue damages respectively. Cheek, upper lip, lower lip, nose, hard palate, maxilla, oral commissure, zygoma, infra-orbital region, mandible, and chin are oftentimes the major facial anatomic regions affected by the disease in the individuals identified in our review. Complete loss of upper lip, lower lip, and nose were also identified as a sequela of Noma.

Discussion

The mortality rate of Noma is reported to vary between 85% and 90%. The few survivors suffer from disfigurement and functional impairment affecting speech, breathing, mastication, and/or even leading to changes in vision. Often, the aesthetic damage becomes a source of stigma, leading to isolation from society, as well as one’s family. Similarly, our review found a high level of facial tissue damage and psychiatric morbidity.

Noma is orofacial gangrene that rapidly disintegrates the hard and soft tissue of the face. The mortality rate of Noma varies between 85–90%. The remaining 10–15% of Noma survivors permanently suffer from severe facial deformities. Noma is a widely neglected disease affecting poor people globally. Most cases of Noma are reported from the so-called Noma belt, located south of the Sahara and runs across Africa from Senegal to Ethiopia. Though Ethiopia is one of the countries in the Noma-belt region where people, particularly children, are significantly affected by the disease, the attention given to this devastating condition is remained to be very low. Therefore, we believe that assessing the severity and sequela of Noma in Ethiopia is crucially essential to lay bare the burden of the disease and increase the overall understanding of the condition among different stakeholders. We are also convinced that the study’s findings can serve as baseline data for further in-depth scientific investigations and preventive policy development.

Noma: Experiences of Survivors, Opinion Leaders and Healthcare Professionals in Burkina Faso

The scientific literature on noma (Cancrum Oris) has clearly increased in recent decades, but there seems to have been limited analysis of issues around the psycho-social impacts of this disease. Even when these issues have been addressed, the focus has tended to be on patient experiences, whereas the community dimension of the disease and the role of healthcare professionals and community leaders in mitigating these impacts remain largely unexplored. A study in the form of semi-directed interviews with 20 noma survivors and 10 healthcare professionals and community leaders was conducted between January and March 2021 in Burkina Faso with the aim of describing the experiences of noma survivors, generating knowledge about living with the burden of the disease and understanding the attitudes of community leaders towards the disease. The results reveal that noma is a disease that affects economically vulnerable populations and leads to extreme household poverty. As far as treatment is concerned, patients tend to turn to practitioners of both traditional and modern medicine. Within communities, noma survivors face discrimination and stigma. The study highlighted a lack of information and knowledge about noma. However, surgical operations lead to patient satisfaction and these remain one of the coping strategies used to tackle the stigma and discrimination. The recommendations set out in this article are aimed firstly at stepping up research into the psycho-social impacts of noma, and secondly at considering these impacts in regional programmes and national plans to combat the disease.

Noma: A Neglected Area for Research

Noma, a debilitating and destructive orofacial gangrene, remains endemic in the poor countries of sub-Saharan Africa and other noma hotbeds across the globe, mainly in countries characterized as underdeveloped economies with significant impoverished populations. Noma mostly affects children and infants. This is in spite of the universally held notion that noma is a preventable disease. Indeed, the current noma status quo has been cast as a human rights shortfall, since this devasting disease overwhelmingly affects children from poor countries. At the recently held Noma Research Day, a renewed call for the World Health Organization (WHO) to recognize and include noma as one of the neglected tropical diseases was accompanied by a recognition that research into all aspects of noma has waned or remained completely lacking-particularly that which addresses the basic science questions of the etiology, pathophysiology/pathobiology, and underlying mechanisms of the disease. Yet, a lack of incremental knowledge on the various aspects of noma continues to hamper our composite understanding of its biology. Without a fundamental understanding of the biology of noma, current preventive measures and treatment modalities will continue to fall short of the goals of prevention and eradication. This opinion piece draws renewed attention to the urgency of listing noma as a neglected tropical disease by the WHO. It also calls for major international research funding agencies, including the WHO and the National Institutes of Health, to renew their resolve to robustly fund structured, collaborative, and coordinated proposals that address questions on the epidemiology, etiology, pathophysiology/pathobiology, and molecular mechanisms of the disease. This is with a view to achieving more effective public health approaches toward prevention and to designing potential therapeutic regimens for early lesions. These steps are key to the ultimate eradication of noma.

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.

Clinical application and outcomes of reconstructive microsurgery in Africa: A systematic review and meta-analysis

BACKGROUND

Reconstructive microsurgical free flap techniques are often the treatment of choice for a variety of complex tissue defects across multiple surgical specialties. However, the practice is underdeveloped in low- and middle-income countries. The aim of this systematic review was to evaluate the clinical application and outcomes of reconstructive microsurgery performed in Africa.

METHODS

Seven databases (PubMed, Web of Science, MEDLINE, CINAHL, Academic Search Complete, Embase, and Google Scholar) were searched for studies reporting microsurgical procedures performed in Africa. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Tools and quality of evidence using the GRADE approach. Meta-analysis was performed using a random effects model to estimate the pooled proportion of events with 95% confidence intervals. The primary outcome was free flap success rate, and the secondary outcomes were the complication and flap salvage rates.

RESULTS

Ninety-two studies were included in the narrative synthesis and nine in the pooled meta-analysis. In total, 1376 free flaps in 1327 patients from 1976 to 2020 were analyzed. Head and neck oncologic reconstruction made up 30% of cases, while breast reconstruction comprised 2%. The pooled flap survival rate was 89% (95% CI: 0.84, 0.93), complication rate 51% (95% CI: 0.36, 0.65), and free flap salvage rate was 45% (95% CI: 0.08, 0.84).

CONCLUSION

This meta-analysis showed that the free flap success rates in Africa are high and comparable to those reported in high-income countries. However, the comparatively higher complication rate and lower salvage rate suggest a need for improved perioperative care.

Noma disease (cancrum oris, orofacial gangrene) in an acute myeloid leukemia patient: a case report

Background

Noma is a rare disease that occurs mainly in malnourished patients in developing countries. Noma starts as facial swelling and gingival necrosis that eventually necrotizes underlying tissues including the jaw bone, leaving severe disfigurement. It is reported extremely rarely in patients with severe immunosuppression or blood dyscrasia.

Case presentation

The gingivitis that occurred in a 12-year-old Asian female patient with acute myeloid leukemia was getting increasingly worse. Although the proper treatment was done, the patient’s condition did not improve, and eventually, a large full-thickness defect was left in the maxillofacial part.

Conclusions

Early diagnosis and management is the only way to prevent the progression, which leads to facial disfigurement. We present a case of noma in a pediatric acute myeloid leukemia patient, in which oral function was restored through surgical intervention.

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.

Josef Mengele's research program on noma in Auschwitz

Noma research protocol was conducted in the Auschwitz Birkernau camp by the infamous (Schutzstaffel) SS doctor Josef Mengele who was known as "the Angel of Death" in close collaboration with researchers at the Kaiser-Wilhelm Institute in Berlin Crimes. Mengele who held the post of camp doctor in the "Gypsy camp" saw an opportunity to set up a research program on gypsy children called "Nomaprojekt". The purpose of this program was to study the causes of noma and to find treatment methods. The experimental treatment protocol consisted of administering a combination of sulfanilamido-ethyl thiodiazole and nicotinic acid. Heads and selected body parts of children suffering from noma were prepared in formaldehyde jars and sent to researchers at the prestigious Kaiser-Wilhelm Institute for Anthropology, Human Heredity and Eugenics in Berlin-Dahlem, but also to the SS Medical Academy in Graz to carry out further examinations. The experimental protocol for the treatment of noma among Gypsy children is one of the most horrific crimes that Dr. Josef Mengele committed in the Auschwitz camp.

Language and beliefs in relation to noma: a qualitative study, northwest Nigeria

Background

Noma is an orofacial gangrene that rapidly disintegrates the tissues of the face. Little is known about noma, as most patients live in underserved and inaccessible regions. We aimed to assess the descriptive language used and beliefs around noma, at the Noma Children’s Hospital in Sokoto, Nigeria. Findings will be used to inform prevention programs.

Methods

Five focus group discussions (FGD) were held with caretakers of patients with noma who were admitted to the hospital at the time of interview, and 12 in-depth interviews (IDI) were held with staff at the hospital. Topic guides used for interviews were adapted to encourage the natural flow of conversation. Emergent codes, patterns and themes were deciphered from the data derived from IDI’s and FGDs.

Results

Our study uncovered two main themes: names, descriptions and explanations for the disease, and risks and consequences of noma. Naming of the disease differed between caretakers and heath care workers. The general names used for noma illustrate the beliefs and social system used to explain the disease. Beliefs were varied; participant responses demonstrate a wide range of understanding of the disease and its causes. Difficulty in accessing care for patients with noma was evident and the findings suggest a variety of actions taking place before reaching a health center or health worker. Patient caretakers mentioned that barriers to care included a lack of knowledge regarding this medical condition, as well as a lack of trust in seeking medical care. Participants in our study spoke of the mental health strain the disease placed on them, particularly due to the stigma that is associated with noma.

Conclusions

Caretaker and practitioner perspectives enhance our understanding of the disease in this context and can be used to improve treatment and prevention programs, and to better understand barriers to accessing health care. Differences in disease naming illustrate the difference in beliefs about the disease. This has an impact on health seeking behaviours, which for noma cases has important ramifications on outcomes, due to the rapid progression of the disease.

Estimated incidence and Prevalence of noma in north central Nigeria, 2010-2018: A retrospective study

Background

Noma is a spreading and fulminant disease believed to be native to Sub-Saharan Africa over the last decade and associated with low socioeconomic status of citizens of the region. Within this noma belt, most epidemiological reports regarding the disease have emanated from the north western region of Nigeria. However, our indigenous surgical mission encountered a substantial number of cases of noma and post-noma defects noteworthy of epidemiological representation across north central Nigeria.

Methods

All noma cases encountered within the 8-year study period were included and divided based on clinical signs into acute and sequelae groups. Incidence estimation was based on acute/recently active cases and was calculated using the statistical method proposed by the WHO Oral Health Unit (1994). Period prevalence of noma was calculated considering the population at risk in the zone.

Findings

A total of 78 subjects were included in the study with age ranging from 2–75 years. Twelve subjects (15.4%) presented with acute disease while 66 (84.6%) had various forms of post-noma defects. The estimated incidence of noma in the north central zone was 8.3 per 100000 with a range of 4.1–17.9 per 100000 across various states. Period prevalence of noma which incorporated all cases seen within the study period was 1.6 per 100000 population at risk.

Conclusion

Although noma may be more prevalent in the north western region of Nigeria, substantial number of cases occurs within the north central zone which calls for deliberate public awareness campaign on disease risk factors and prevention, and education of primary health-care providers.

Noma, a devouring disease of the orofacial complex, is commonly associated with poverty and impoverished regions of the world especially Sub-Saharan Africa termed the noma belt region of the world. With more reports advocating for full inclusion of noma in the WHO Neglected Tropical Diseases (NTDs) program, the apparent neglect of the disease in north central Nigeria compared to other sub-regions is worrisome as the disease burden in the sub-region has not been reported till date. In this light, a retrospective, cross-sectional survey was conducted to provide epidemiological representation to the cases encountered within an eight-year period by the Cleft and Facial Deformity Foundation (CFDF), an indigenous surgical mission. The incidence of noma was estimated using methods recommended by WHO while the period prevalence was calculated considering the population living below poverty line in the sub-region. This study extrapolates an incidence of 8.3 cases per 100000 and a period prevalence of 1.6 per 100000 persons at risk. Notable is the finding that most individuals encountered were above thirty years of age and suffered varying degree of facial disfigurement consequent to acute noma disease experienced in their childhood/early adolescence. Therefore, we advocate public awareness on the disease risk factors and prevention within the sub-region as well as training of primary health personnel on disease identification, primary care and nearest referral centres. We also identify the need to bolster the efforts of existing health facilities and indigenous surgical missions in the management and rehabilitation of noma cases and survivors.

Noma surgery

OBJECTIVE

Noma is a devastating and destructive disease of the face for which there is a dearth of information regarding surgical options. Herein, we describe the facial deformities and patient characteristics in a patient population affected by noma and the surgical approaches used in treatment.

METHODS

Retrospective case series of a Doctors Without Borders (Médecins Sans Frontières) intervention at Sokoto Children's Noma Hospital in northern Nigeria, the highest-volume noma hospital in the world.

RESULTS

Twenty-two procedures were performed on 18 patients with noma, 44% of whom were children. The majority of patients (n = 10, 55.5%) were made aware of surgical care through a Doctors Without Borders outreach program. Patients' reasons for seeking care included functional (61.1%, n = 11), appearance (61.1%, n = 11), and social stigma (66.7%, n = 12). The majority (83.3%, n = 15) had lip involvement. Four patients (22.2%) underwent staged flap procedures including prelamination, flap delay, or pedicle division. The mean duration of surgical procedure was 87 minutes (range 5-306 minutes). The minor complication rate was 16%. There were no major complications or deaths.

CONCLUSION

Noma is a mutilating disease of the face that occurs in settings of extreme malnutrition. A total of 55.5% of noma patients were made aware of surgical care through outreach programs. The majority of noma patients seek care to improve function (61.1%) and appearance (61.1%), and to address social stigma (66.7%). A total of 83.3% of noma patients had lip involvement. Facial reconstructive surgeons must rely on principles of congenital, traumatic, and oncologic deformity repair while focusing on safe, reliable procedures for low-resource settings.

What Is the Role of Plastic Surgery in Global Health? A Review

There is growing awareness of the substantial global burden of surgical disease. Conditions treated effectively by plastic and reconstructive procedures make a large proportion of the global surgical diseases, and disproportionately affect individuals at the lower end of the economic spectrum. This article reviews the role of plastic surgery in global health, highlights the ongoing need for plastic and reconstructive surgery globally, and increasing efforts that have been made to meet these needs. There global shortage of plastic surgeons in low and middle income countries, but plastic surgery has a long tradition of humanitarian aid, has been a leader in global surgery development. Plastic and reconstructive surgical care has increasingly been shown to be cost effective and to have an immense impact on the economy of a region, delivering a substantial return on investment. More sustainable global surgical care is essential in future, requiring ongoing efforts from the plastic surgery community, greater recognition of the problems that can be addressed at policy level, and research to help guide policy-makers when facing the decision of allocating scarce resources. There is a fundamental role of plastic surgery in global health.

Noma as a complication of false teeth (Ebiino) extraction: a case report

Background

Ebiino, also known as false tooth extraction, is a traditional practice done mainly in the remote areas of African countries, including Uganda. It involves the extraction of tooth buds in babies with common childhood illnesses such as fever, cough, and diarrhea. It is thought that the tooth buds are responsible for the ailments seen in these infants. The practice is performed by traditional healers using unsterile instruments. The complications associated with this dangerous practice have been mentioned in the literature and include anemia and septicemia, among others. This case report describes a baby with noma, an orofacial gangrenous infection.

Case presentation

A 16-month-old girl from western Uganda belonging to the Banyankole ethnic group was admitted to Mbarara University Teaching Hospital with a 5-day history of a dark lesion on the left cheek. The lesion had started from the left upper gum at the site where a tooth bud had been extracted 1 week prior to admission. The child had experienced occasional cough and fever and also had erupting tooth buds. These tooth buds had been seen as the cause of the cough and fever by the traditional herbalist; hence, they were extracted. An unsterile instrument had been used for the procedure. At the hospital, a local examination showed necrotic tissue involving the left cheek and extending into the left upper gingival area of the girl’s mouth. A clinical diagnosis of orofacial gangrene (noma) was then made.

Conclusions

Ebiino, or false tooth extraction, is still practiced in some remote areas of Uganda. Noma has been mentioned as a possible complication of this traditional practice; however, case reports in the literature are scant. Public awareness of the dangers of this practice is therefore still required to prevent this dangerous complication.

Noma: Overview of a Neglected Disease and Human Rights Violation

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.

Microvascular reconstruction of facial defects in settings where resources are limited

The surgical treatment of defects caused by noma is challenging for the surgeon and the patient. Local flaps are preferred, but sometimes, because of the nature of the disease, there is not enough local tissue available. We describe our experience of free tissue transfer in Ethiopia. Between 2008 and 2014, 34 microsurgical procedures were done over 11 missions with the charity Facing Africa, predominantly for the treatment of defects caused by noma (n=32). The mean duration of operation was 442 minutes (range 200 - 720). Six minor wound infections were treated conservatively and did not affect outcome, a return to theatre was required in 4 patients with wound infections and one with a haemorrhage; 2 flaps failed and 2 partially failed, one patient developed an oronasal fistula, and one had an infection at the donor site that required a repeat graft. In settings where resources are limited, free flaps can be used when local tissue is not available and they cause less morbidity than pedicled tissue transfer.

[Noma]

Noma is a necrotizing ulcerative stomatitis known since Antiquity. It occurs mostly in poor countries, the Sahel countries being the most affected. Each year, several hundred thousand cases are reported. Noma affects especially malnourished children who are less than 6 years old and rarely adults with acquired immunodeficiency (HIV, cancer). Ulcerative lesion is occurring rapidly due to the production of endotoxins by bacteria from oral commensal, telluric and animal origin. Necrotic debridement leads to huge defects: loss of soft tissue (skin, nerves, vessels, eye), bone (maxilla, mandible) and teeth. Death occurs rapidly in a few weeks in 80 % of the cases. In case of survival, the consequences are functional, aesthetic, psychological and social. The goal of the treatment in the acute phase is the patient's survival and the fight against limited mouth opening. The management of the phase of sequela is an anaesthetic, surgical and physiotherapy challenge. Its purpose is the social reintegration of the patient.

A Review on Noma: A Recent Update

Noma is a gangrenous infection primarily affecting under developed countries. The aim of this paper was to review all recent articles on noma from January 2003 to August 2014 and briefly update the latest information related to the topic. A literature search was done on PUBMED using the keywords “noma / cancrum oris”. Noma is commonly seen in malnourished children. There has been an increased incidence of noma in HIV patients. Apart from these, noma has also been reported in association with cyclic neutropenia, herpetic stomatitis, leukemia, Down's syndrome and Burkett's disease. Treatment of acute noma includes transfusion of blood and intravenous fluids, administration of antibiotics, putting the patient on a high protein diet and debridement of necrotic areas. Surgical phase is usually initiated 6 to 18 months after a period of quiescence. Although, the mortality rate associated with noma has reduced significantly with the advent of modern generation antibiotics, the functional, cosmetic and psychological challenges associated with the destruction of soft or hard tissues still remains a huge challenge. Adequate steps must be implemented by the government or medical professionals to prevent the disease and provide an early intervention.

Management of extra-capsular temporo-mandibular joint ankylosis: does conservative approach to treatment have a role?

BACKGROUND

The conventional management of fibrous extracapsular temporo-mandibular joint (TMJ) ankylosis, a debilitating disease, is associated with surgical complications and financial burden on the patients.

OBJECTIVE

To assess the outcome of conservative approach to the management of fibrous extracapsular TMJ ankylosis.

PATIENTS AND METHODS

This is a prospective study of patients who presented at the Dental and Maxillofacial Surgery Clinic of the University of Calabar Teaching Hospital, Nigeria, during the period from January 1999 to December 2012 with a history of inability to open the mouth diagnosed as fibrous extracapsular TMJ ankylosis.

RESULTS

Twenty-one subjects were treated and their ages ranged from 11 to 22 years with mean at 15.0 years. There were 13 (61.9 %) males and 8 (38.1 %) females with male: female ratio of 1.6:1. The aetiological factor that predisposed to formation of extracapsular TMJ ankylosis was facial trauma. There was no facial asymmetry and the side distribution of the affliction showed that 1 (4.8 %) was bilateral while 20 (95.2 %) were unilateral. Eight cases (38.1 %) were incomplete ankylosis while the rest (n = 13, 61.9 %) were complete. The shorter the duration of fibrous ankylosis and the greater the initial inter-incisal distance before treatment, the better the treatment outcome.

CONCLUSION

The outcome of treatment suggests that the conservative approach to management of this condition was beneficial to these patients because they presented early. However, randomized controlled clinical trials are needed to validate this treatment option.

Paul Tessier facial reconstruction in 1970 Iran, a series of post-noma defects

BACKGROUND

Paul Tessier was a pioneering plastic surgeon who founded craniofacial surgery and had an international influence in the field of reconstructive surgery. We reviewed his techniques in the reconstruction of post-noma defects in Iran in the late 1970s.

PATIENTS AND METHODS

We studied a series of 23 patients operated on by Tessier from 1974 to 1978 in Iran (property of Association Française des Chirurgiens de la Face). They all suffered from noma in childhood with major facial defects.

RESULTS

Ten suffered from simple lip and cheek defects, nine also from nose defects and four from extensive facial defects. Abbe flaps were used in 15 patients to reconstruct the lips completed by commissuroplasty in six patients. Nose defects were reconstructed with nasofrontal flaps (ten cases). The outer cheek was reconstructed with a rotation flap (four cases), or with a frontotemporal flap (six cases). The inner cheek was reconstructed using a Barron-Tessier myocutaneous flap (ten cases). Of the 23 patients, partial flap necrosis occurred in five cases.

CONCLUSIONS

Tessier was a pioneering plastic surgeon who used local flaps to reconstruct these important facial defects. He had a high rate of success, although nowadays local flaps are commonly replaced by free flaps.

Gillies fan flap for the reconstruction of an upper lip defect caused by noma: case presentation

The case of a 65-year-old noma patient with a defect involving her upper lip is presented. The defect also included missing teeth numbers eleven, twelve, 21, and 22 and the adjoining alveolus. One-stage lip reconstruction was carried out with Gillies fan flap followed by vestibuloplasty and commissuroplasty. An acrylic partial denture was subsequently fabricated to replace the missing teeth and thereby restore function. Even though the incidence of cancrum oris has reduced worldwide, cases are still being reported in Africa and can leave behind a significant facial defect. Whereas most cases of lip defects reported from the Western world are due to cancer, cancrum oris could be the cause of lip defects in sub-Saharan Africa. Gillies fan flap could be employed for the reconstruction of a relatively large defect of the lip and the disadvantage of microstomia could be minimized for the restoration of articulation, speech, and masticatory functions of the lip.

Global Oral Health Inequalities

Four oral mucosal infections were identified as Global Oral Health Priorities: (a) HIV and associated viral, bacterial, and fungal infections; (b) tuberculosis; (c) NOMA; and (d) sexually transmitted diseases. Huge global inequalities exist in all four. HIV-associated infections constitute the major challenge. Oral manifestations of AIDS can be specifically diagnostic, indicating a significant role for dentists within health teams. The World Workshops in Oral Health & Disease in AIDS have identified a research program, elements of which are being implemented. Data on oral mucosal involvement in tuberculosis, syphilis, and gonorrhea are incomplete in developed countries and virtually non-existent in low- and middle-income countries, indicating the need for further epidemiological studies. Oral manifestations of tuberculosis and sexually transmitted diseases are largely associated with general health, so action programs should be integrated with agencies treating the systemic diseases. NOMA is very much in the oral health domain. It is a preventable disease associated with malnutrition and unidentified bacterial factors. Prevalence is probably grossly overestimated at present; but nevertheless it constitutes a challenge to the profession, especially in the NOMA belt. Current treatment is surgical, but plans for its eradication should be achievable. The global oral health community, especially the IADR, has a major role to play.

NOMA: A Preventable "Scourge" of African Children

Noma is a serious orofacial gangrene originating intraorally in the gingival-oral mucosa complex before spreading extraorally to produce a visibly destructive ulcer. Although cases of noma are now rarely reported in the developed countries, it is still prevalent among children in third world countries, notably in sub-Sahara Africa, where poverty, ignorance, malnutrition, and preventable childhood infections are still common. This review summarizes historical, epidemiological, management, and research updates on noma with suggestions for its prevention and ultimate global eradication. The global annual incidence remains high at about 140,000 cases, with a mortality rate exceeding 90% for untreated diseases. Where the patients survive, noma defects result in unsightly facial disfigurement, intense scarring, trismus, oral incompetence, and social alienation. Although the etiology has long been held to be infectious, a definitive causal role between microorganisms cited, and noma has been difficult to establish. The management of noma with active disease requires antibiotics followed by reconstructive surgery. Current research efforts are focused towards a comprehensive understanding of the epidemiology, and further elucidation of the microbiology and pathogenesis of noma.Although a formidable public health challenge, noma can be prevented with a potential for subsequent global eradication. To achieve both desirable goals, detection of early disease is crucial because these early lesions respond to conventional antibiotic treatments when instituted side by side with nutritional rehabilitation, and obviates the necessity for extensive surgical reconstruction often indicated in late stage disease. The eradication of noma in the developed world in the mid 20(th) century bears out the notion of a similar outcome following effective preventive strategies in Africa. A fundamental and necessary step towards attaining this goal is for the international community to adopt a perception of noma as an urgent global public health challenge. Research effort toward deciphering the microbiology, molecular events, and pathogenesis of noma also should intensify.

Visor flap for total upper and lower lip reconstruction: a case report

Introduction

Noma, aptly named the 'face of poverty', is a scourge with a mortality rate of up to 90% that affects some 140,000 people each year, predominantly children in the sub-Saharan 'noma belt'. Survivors of the acute attack suffer severe facial disfigurement from loss of facial tissue and scarring. Surgical reconstruction of noma defects is a major challenge, especially in Africa, where the majority of cases occur.

Case presentation

We report the case of a 40-year-old Somali man who presented with severe facial disfigurement, including total absence of both upper and lower lips. After a failed initial reconstruction, a combination of platysma flaps and a left deltopectoral flap provided mucosal lining, while a scalp visor flap served to recreate upper and lower lips, the beard and moustache.

Conclusion

The scalp visor flap offers a simple but extremely versatile tool for use in midfacial reconstruction, especially in the male, providing neo-lip tissue, a moustache and a beard. This is the first report of a simultaneous total upper and lower lip reconstruction using a scalp visor flap, in the English literature. We also emphasize on a process of transfer of skills to enable local surgeons to effectively manage the challenge that noma presents.

Noma (cancrum oris) in human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV and AIDS): clinical experience in Zimbabwe

PURPOSE

This retrospective study describes the clinical features and management of noma (cancrum oris) in patients with HIV and AIDS.

PATIENTS AND METHODS

Records of 48 consecutive patients with noma (cancrum oris) seen between July 2002 and November 2006 were reviewed for age, gender, clinical features, and management. Other reports on noma in HIV and AIDS in Zimbabwe were also reviewed.

RESULTS

There were 48 patients included; 35.4% (n = 17) were males, of which 64.7% (n = 11) were children (16 years and younger) and 35.3% (n = 6) were adults; 64.6% (n = 31) were females, out of which 87.1% (n = 27) were children and 12.9% (n = 4) were adults. The average age was 14.2 years (range, 3 to 30 years) for males and 9.2 years (range, 1 to 36 years) for females. The average age for the entire group was 11 years (range, 1 to 36 years). All patients were HIV-positive by the ELISA method. Only 13 patients had CD4 cell and CD8 cell count obtained, ranging from 10 to 594 cells/microL with a CD4/CD8 ratio ranging from 0.02 to 0.45. Only 5 patients had microbiologic investigations conducted, isolating Staphylococcus aureus, Klebsiella species, group D Streptococcus, and group B hemolytic Streptococcus. Isolated cheek defect (37.5%) was most common, followed by the type I and type IV defect (25% each). Administration of antibiotics, nutritional support, wound debridement, and sequestrectomy were conducted before definitive reconstructive surgery. Facial reconstruction was performed using distant and local advancement flaps. No bony reconstruction was performed. Satisfactory results were achieved with minimal infection and flap breakdown. Follow-up was difficult; patients were lost to follow-up within 6 to 12 months after surgery.

CONCLUSION

Noma cases are on the increase in line with the current HIV and AIDS epidemic. Female children appear to be more commonly affected than their male counterparts. Reconstructive surgery is possible in patients with low CD4/CD8 ratios because of HIV infection.

Nasofacial Phycomycosis

Nasofacial phycomycosis caused by Conidiobolus is a rare fungal infection most often encountered in the developing world in conditions of poverty. A clinical presentation of the natural history of this condition observed over a period of 6 years by a visiting volunteer surgical team demonstrates the role of multimodality surgical and antifungal drug treatment in producing a successful outcome. The particular sensitivity of this infection to the new generation antifungal Voriconazole is noted.

Noma (cancrum oris)

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 use of the pedicled supraclavicular flap in noma reconstructive surgery

Three noma patients with large unilateral facial defects were reconstructed using the pedicled supraclavicular flap technique in the Noma Children Hospital in Sokoto, Nigeria. The results are-although not completely perfect-encouraging enough to report and to repeat the technique in future reconstructive noma surgery after moderate modifications. It is advised not to tunnel the pedicle in the neck, but instead to open the neck. Then, the flap can be inset in a Z-plasty fashion to close the neck without the chance of compression of the pedicle of the flap. In this way flap necrosis can be prevented, without the risk of a scar contracture of the neck. Another technique, which can prevent partial flap necrosis and loss of tissue, with the need for secondary stage interventions, is a delay procedure of the flap. Incorporation of the fascia in the pedicled supraclavicular flap can be another option to fulfil the abovementioned requirements.

Submental intubation for cancrum oris: a case report

Cancrum oris (Noma) is a devastating gangrenous disease that leads to severe tissue destruction in the face. We describe the anesthetic management of a 12-year-old girl with cancrum oris sequelae in a Rural Secondary level Hospital in Central India (Padhar Hospital). She presented with a large defect in her upper lip on the left side that extended into the columella and the floor of the left nostril. She was scheduled to undergo reconstructive surgery and the surgeons planned to use an Abbé flap based on the lower lip. For this, access to both the mouth and the nose was required. We considered a tracheostomy but decided to attempt the submental route for orotracheal intubation. Following intravenous induction the patient's trachea was intubated with a cuffed oral tracheal tube. This was passed through the submental incision and then reconnected. The surgery proceeded uneventfully and the patient was extubated before transfer. She made a satisfactory recovery and the submental scar healed without complication or scarring. We describe briefly the features of cancrum oris and review the technique of submental intubation (described in adults with midfacial trauma). The use of submental intubation in children and for cancrum oris sequelae has not been previously reported.

Temporal relationship between the occurrence of fresh noma and the timing of linear growth retardation in Nigerian children

BACKGROUND

Fresh noma (cancrum oris) occurs predominantly in children <4 years of age. The key risk factors are poverty, malnutrition and infections. Evolution from an intraoral inflammation to a grotesque oro-facial gangrene is very rapid.

OBJECTIVE

We assessed potential relationship between the occurrence of fresh noma and linear growth retardation (LGR) which is prevalent in deprived Third World infants/children between ages 3 and 30 months. LGR is attributed to malnutrition and chronic immunostimulation by environmental antigens.

DESIGN

Anthropometric evaluation of children (n = 91) with fresh noma, ages 0-8 years, in relation to US National Center for Health Statistics Reference values was carried out. Age-matched noma-free, poor village children (n = 151) from similar communities as noma cases, and elite urban children (n = 132) served as control groups. Heights and weights were measured and the height for age (HAZ), weight for age (WAZ) and weight for height (WHZ) scores calculated as indices of stunting, underweight and wasting respectively. Serum level of interleukin (IL)-18, a multifunctional cytokine, was also measured.

RESULTS

In the age groups 0-4 and 4-8 years, the percentages of noma children <-2.0SD were 91% and 67% respectively. The corresponding values for the village children were 37% and 24% and significantly different (P < 0.001) from the noma group. Only 7% of the elite children aged 4-8 years were stunted. Low body weight and wasting were prominent features of village and noma groups, but more marked in the latter. Associated with noma was a profound increase (P < 0.001) in IL-18 in comparison with urban controls, and a 34% non-statistically significant increase relative to the village control group. Among other functions, IL-18 induces several pro-inflammatory cytokines and the matrix metalloproteinases, influences long bone growth, and consequently may be relevant to growth retardation seen in poor village children and noma victims.

CONCLUSION

These results suggest that occurrence of fresh noma was probably programmed very early in life by malnutrition and chronic infections resulting from replacement of breast milk with contaminated, inferior substitutes. Although not investigated, we speculate that children with fresh noma might also be victims of intrauterine growth retardation as noma is most prevalent during the infantile phase of child growth which starts at mid-gestation and tails off at 4 years.
