Immune Markers Are Associated With Asymptomatic Intracranial Large Artery Stenosis and Future Vascular Events in NOMAS. Stroke 2023; 54:3030-3037. [PMID: 37909207 PMCID: PMC10842368 DOI: 10.1161/strokeaha.123.044237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 10/13/2023] [Indexed: 11/02/2023]
Abstract
BACKGROUND Inflammation contributes to atherosclerosis but is incompletely characterized in intracranial large artery stenosis (ICAS). We hypothesized that immune markers would be associated with ICAS and modify the risk ICAS confers on future vascular events. METHODS This study included a subsample of stroke-free participants in the prospective NOMAS (Northern Manhattan Study), who had blood samples analyzed with a 60-plex immunoassay (collected from 1993 to 2001) and ICAS assessment with time-of-flight magnetic resonance angiography (obtained from 2003 to 2008). We dichotomized ICAS as either ≥50% stenosis or not (including no ICAS). We ascertained post-magnetic resonance imaging vascular events. We used least absolute shrinkage and selection operator procedures to select immune markers independently associated with ICAS. Then, we grouped selected immune markers into a derived composite Z score. Using proportional odds regression, we quantified the association of the composite immune marker Z score, ICAS, and risk of vascular events. RESULTS Among 1211 participants (mean age, 71±9 years; 59% women; 65% Hispanic participants), 8% had ≥50% ICAS. Using least absolute shrinkage and selection operator regression, we identified CXCL9 (C-X-C motif chemokine ligand 9), HGF (hepatocyte growth factor), resistin, SCF (stem cell factor), and VEGF-A(vascular endothelial growth factor A) to have the strongest positive relationships with ≥50% ICAS in fully adjusted models. Selected markers were used to derive a composite immune marker Z score. Over an average follow-up of 12 years, we found that each unit increase in immune marker Z scores was associated with an 8% (95% CI, 1.05-1.11), 11% (95% CI, 1.06-1.16), and 5% (95% CI, 1.01-1.09) increased hazard of death, vascular death, and any vascular event, respectively, in adjusted models. We did not find a significant interaction between immune marker Z scores and ICAS in their relationship with any longitudinal outcome. CONCLUSIONS Among a diverse stroke-free population, selected serum immune markers were associated with ICAS and future vascular events. Further study is needed to better understand their role in the pathogenesis of ICAS and as a potential therapeutic target in stroke prevention.

Abstract
Prior work in the Northern Manhattan Study (NOMAS) identified impaired cognition in cross-sectional analyses and more rapid memory decline in individuals with evidence of prior common infectious disease exposures. In this study, we sought to determine the cross-sectional relationship between prior exposure to cytomegalovirus, herpes simplex viruses 1 and 2, Chlamydia pneumoniae, and Helicobacter pylori and three magnetic resonance imaging (MRI) signatures (whole-brain cortical thickness, a previously validated AD signature, and hippocampal volume) in 455 NOMAS participants. We performed confounder-adjusted linear regression analyses between neuroimaging scores and both continuous serologies and categorical seropositivity of each pathogen, as well as a combined infectious burden index (IBI). We identified that increased serologic titers of herpes simplex virus 2 were associated with reduced whole-brain cortical thickness, and a combined score of HSV-2 and C. pneumoniae displayed an additive effect on reduced cortical thickness. Our findings suggest herpes simplex virus 2 seropositivity may contribute to accelerated brain aging, possibly resulting in an increased vulnerability to cognitive impairment and neurodegenerative disease in aging populations.

Abstract
OBJECTIVES Noma is a facially disfiguring disease that affects the oral cavity and midface structures. If left untreated, the disease is fatal. Noma causes severe cosmetic and functional defects in survivors, leading to psychiatric and social problems. However, there are limited data on psychosocial and functional sequelae associated with this disease. This cross-sectional study aimed to investigate psychosocial and functional morbidity among facially disfigured untreated Noma cases. Study participants were volunteer patients diagnosed with noma and awaiting surgery at two noma treatment centers in Ethiopia. A questionnaire derived from the APA's DSM-5, the DAS59, and the Appearance Anxiety Inventory protocol was used to measure the psychosocial and functional morbidity of the cases between September 16 and October 10, 2022. RESULTS A total of 32 noma cases (19 women and 13 men) awaiting the next surgical campaigns were involved in the study. Study participants reported severe social (Likert score = 2.8) and psychological (Likert score = 3.0) morbidity. Functional limitation was moderate (Likert score = 2.9). This study has shown that psychosocial and functional morbidity in untreated noma cases in Ethiopia is substantial. Therefore, policymakers, clinicians, and researchers need to pay sufficient attention to providing adequate health care and preventing the occurrence of the disease in the long term.

Abstract
BACKGROUND Intracranial large artery stenosis (ILAS) is an important contributor to ischemic stroke in the United States and worldwide. There is evidence to suggest that chronic exposure to certain infectious agents may also be associated with ILAS. We aimed to study this association further in an ethnically diverse, prospective, population-based sample of Northern Manhattan. METHODS We enrolled a random sample of stroke-free participants from an urban, racially, and ethnically diverse community in 1993. Participants have been followed prospectively and a subset underwent brain magnetic resonance angiograms from 2003 to 2008. Intracranial stenoses of the circle of Willis and vertebrobasilar arteries were scored as 0=no stenosis, 1≤50% (or luminal irregularities), 2=50% to 69%, 3≥70% stenosis, and 4=flow gap. We summed the individual score of each artery to produce a global ILAS score (possible range, 0-44). Past infectious exposure to Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpes simplex virus 1 and 2 was determined using serum antibody titers. RESULTS Among 572 NOMAS (Northern Manhattan Study) participants (mean age 71.0±8.0 years, 60% women, 68% Hispanic) with available magnetic resonance angiogram and serological data, herpes simplex virus 2 (beta=0.051, P<0.001) and cytomegalovirus (beta=0.071, P<0.05) were associated with ILAS score after adjusting for demographics and vascular risk factors. Stratifying by anterior and posterior circulations, herpes simplex virus 2 remained associated with the anterior circulation (beta=0.055 P<0.01) but not with posterior circulation ILAS score. CONCLUSIONS Chronic infectious exposures, specifically herpes simplex virus 2 and cytomegalovirus were associated with asymptomatic ILAS as seen on magnetic resonance angiogram imaging. This may represent an additional target of intervention in the ongoing effort to stem the substantial global burden of strokes related to ILAS.

Abstract
OBJECTIVE Little information is available about prevalence of psychiatric morbidity among adult patients who suffered from cancrum oris in Nigeria. The objective of this paper was to assess the prevalence of psychiatric morbidity among patients of cancrum oris in Nigeria. METHOD A cross sectional controlled study was conducted in 2005 comprising 200 adult patients of cancrum oris. Data was collected through self administered questionnaire from the patients. Psychiatric morbidity was assessed using General Health Questionnaire (GHQ) 28. RESULTS Prevalence of psychiatric morbidity was 37% which was about three times that of the control. Psychiatric morbidity was more prevalent among female patients. Other factors associated with high prevalence of psychiatric morbidity include being never married, no formal education and unemployed status. CONCLUSION Psychiatric morbidity is prevalent among cancrum oris patients with differences between both sexes. Being never married, no formal education and unemployed status were other associated factors.

Abstract
Anaesthesiologists, paediatricians, paediatric intensivists and emergency physicians are routinely challenged with airway management in children and infants. There are important differences from adult airway management as a result of specific features of paediatric anatomy and physiology, which are more relevant the younger the child. In addition, a number of inherited and acquired pathological syndromes have significant impact on airway management in this age group. Several new devices--e.g. different types of laryngeal mask airways in various sizes, small fibre-endoscopes--have been introduced into clinical practice with the intention of improving airway management in this age group. Important new studies have gathered evidence about risks and benefits of certain confounding variables for airway problems and specific techniques for solving them. Airway-related morbidity and mortality in children and infants during the perioperative period are still high, and only a thorough risk determination prior to and continuous attention during the procedure can reduce these risks. Appropriate preparation of the available equipment and frequent training in management algorithms for all personnel involved appear to be very important.

Abstract
Noma (cancrum oris) is an orofacial gangrene, which during its fulminating course causes progressive and mutilating destruction of the infected tissues. The disease occurs mainly in children with malnutrition, poor oral hygiene and debilitating concurrent illness. Noma is well documented in the literature, but because most patients do not report to a doctor until the disease is at an advanced stage, its onset and progression remain a mystery. This case report, with a survey of recent relevant literature, highlights the different stages in the development of tissue necrosis, including onset and progression, with an emphasis on the need for early diagnosis and prompt treatment.

Abstract
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.

Abstract
Noma defects of the anterolateral face are often associated with fibrous or bony ankylosis fusing the mandibula to the skull base. According to the extent of the ankylosis, the temporomandibular joint mobility can be restricted or even completely frozen. In third world conditions the surgical approach to severe forms of bony ankylosis consists of a single linear opening osteotomy (trismus release) and the closure of the noma defect with locoregional flaps. Relapse of jaw immobility is common and may be caused by minor bone resection, the lack of adequate postoperative physiotherapy, or even the scarring of the defect coverage. In 4 years the authors have gained increasing experience with folded free flaps for simultaneous closure of outer and inner lining of large noma defects and the maintenance and training of re-established jaw function by the use of a dynamic external distractor fixed between the zygoma and the mandibular body. The authors report the bony reankylosis can be reduced by extended wedge osteotomies of the bony bridge and tip-like shaping of the ascending mandibular ramus. To preclude the reossification of the osteotomy site and fibrous scar formation, a dermofatty or muscular tail of the free flap is interposed into the bone gap. Two cases were treated according to this concept with a free parascapular and a latissimus dorsi flap in combination with simultaneous arthroplasty. During a 6-month follow-up period, no signs of a recurrent reduction of mandibular movement were noted in either case.

Abstract
The aim of the study was to compare dental caries status and the number and type of oral mucosal lesions in HIV positive children from a hospital outpatient department and an institutionalized setting. Oral examinations were performed using presumptive diagnostic criteria. The Fisher's Exact and the Mann-Whitney tests were used for statistical comparison of the two study groups. A total of 169 children were examined of whom 42% were institutionalized and 58% hospital outpatients. One institutionalized child presented with Noma. Twenty-one percent of the institutionalized population presented with molluscum contagiosum, while none of the hospital outpatients presented with this condition. Significantly more intraoral mucosal lesions were observed in the hospital compared with the institutionalized group. The most frequently encountered oral lesion was candidiasis. Pseudomembranous candidiasis was the most common type. Twice as many intraoral ulcers were recorded in the institutionalized group. Thirty-nine percent of the hospitalized patients had multiple lesions compared with 28% in the institutionalized group. Almost three quarters of both populations were caries-free. The mean DMFT was considerably higher in the hospital population. For both the permanent and primary teeth, the decayed component (D/d) made up the major part of the DMFT/dmft, followed by the missing (M/m) component. No fillings were recorded in either the primary or permanent teeth for both groups. Oral lesions are common in HIV populations and were seen in both the hospital and institutionalized groups, at high prevalence levels (63 and 45%). HIV infected children should be considered high risk for caries because of the use of chronic medications, and to receive appropriate care in terms of both treatment and services.

Abstract
Noma is a grangenous stomatitis which might extend to other facial structures leading to extensive soft tissue and bony defects. Reconstruction of noma sequellae should take into account a few principles in relation to the particular aspect of this disease: (1) correction of the mandibular constriction; (2) removal of scar tissue in order to recreate the initial defect; (3) reconstruction of the missing bony framework; (4) reconstruction of the maxilla and upper lip before building the nose in case it is destroyed; (5) anticipation of the facial growth. Reconstruction of the lips, in case of extensive defects often necessitates a distant skin flap. As free flaps, the forearm fascio-cutaneous flap or the serratus musculo-cutaneous flap were used according to the size of the defect. The mucosal part of the lip is usually reconstructed with a local flap from the adjacent lip or an heterolabial flap (Estlander flap).

Abstract
Noma (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. Recently, cases have been reported in adults especially elderly patients or during immunodeficiency states. Reconstructive surgery is often necessary to deal with destruction and sequel but is rarely accessible in developing countries. We report one case of noma (cancrum oris) in an HIV seropositive patient at the National Hospital in Bobo-Dioulasso. The noma was inaugural of AIDS in a 40 years old labourer coming back from Ivory Coast and no major opportunistic infection was associated. The course was fulminant leading to extensive facial gangrene with recurrent bacterial infections. The disease was fatal in this depressive, malnourished and diarrhoeic patient despite local surgical treatment, prolonged antibiotherapy and supportive care. Pathogenic mechanisms, management and preventive issues are discussed.

Abstract
We report a cohort of 148 African children operated on between 1985 and 2000 for noma sequelae. A total of 440 operations were performed. Lesions included mouth constriction in 70 of 148 cases, and severe bone destruction in 69 of 148 cases. A large proportion of children was transferred to Switzerland for surgical treatment, whereas the others were operated on in local hospitals in Africa. Vascularized calvarium flap was mostly used for bone reconstruction (n = 36). Pedicled latissimus dorsi myocutaneous flap was the preferred strategy for cheek reconstruction (n = 40). Expanded frontal flap was used for nasal reconstruction (n = 18), and pedicled heterolabial flap for lip construction (n = 37). Given the elevated level of recurrence of mouth constriction (extraarticular ankylosis), a minimum of 2 years' follow-up after surgical treatment was considered mandatory. Follow-up was conducted by field nurses from the humanitarian organizations, and a third of the patients were seen directly by our surgical team during special missions to Africa.

Abstract
Cancrum oris (noma) is a gangrenous infection that develops in the mouth and spreads rapidly to other parts of the face. The disease occurs mostly in conditions of poverty, poor hygiene and malnutrition. In sub-Saharan Africa the frequency in several countries is estimated to be 1-7 cases per 1,000 population, and as many as 12 cases per 1,000 in the most affected communities. About 90% of these children die without receiving any care, yet the disease can, and should, be prevented. With increasing numbers of children who are malnourished and who have compromised immune systems (compounded by the HIV pandemic) the prevalence of conditions such as noma is likely to increase. Among the earliest features of noma are excessive salivation, marked fetor oris, facial oedema and a greyish-black discolouration of the skin in the affected area. This devastating gangrenous lesion may involve the cheek, the chin, the infra-orbital margin, palate, nose, antrum and virtually any part of the face. This report describes a 4-year-old HIV-positive African girl, who was abandoned, discharged from the Plastics Unit and now lives in a child care sanctuary. Little is known about her history prior to her arrival at the home a few weeks previously. The clinical examination revealed a delay in growth and physical development equivalent to that of a 2-year-old child. The left cheek had a perforating ulcer in a healing phase. The perforation, about 1 cm in diameter, was surrounded by oedematous tissues showing a mild to moderate erythema. The peripheral oedema extended to the lower palpebral, the upper labial, left labial commissural, mandibular and pre-parotid regions. Submental, submandibular and cervical lymph nodes were mildly painful upon palpation. The child was not pyretic. The intra-oral examination revealed the features of acute necrotising gingivitis (ANG). ANG was generalised and showed classic interdental crater-like ulcers covered with whitish debris. Halitosis was pronounced. Examination of the second quadrant revealed a large ulcer extending from the distal aspect of the deciduous canine to the distal aspect of the second deciduous molar. The adjacent palatal mucosa was severely oedematous. The alveolar bone supporting the first and the second molars was completely exposed to the fundus of the vestibulum. It was not possible to obtain intraoral photographs or radiographs. Chlorhexidine gluconate (0.2% solution) and metronidazole tablets, 200 mg twice daily for 15 days were prescribed. The child was seen every alternate day for 10 days and her condition improved rapidly. Halitosis had subsided. She was then referred to the Johannesburg Hospital for further treatment under general anaesthesia. The proposed treatment plan was as follows: removal of dental accretions and polishing of all teeth, extraction of the left maxillary teeth supported by non-vital bone, resection of the necrotic bone in the left maxilla and reconstructive surgery in the left cheek.

Abstract
The authors describe a case of Noma or Cancrum Oris, an oral gangrenous disease, features more frequently found in children from developing countries. The clinical features, its ethiopathogenesis, and its particular link with different geographic and economic areas of the world, its clinical evolution as well as surgical treatment are all discussed. Underlined is the functional and organic aspect of this disease, in particular the distortion of the face, which commonly involves the full thickness of the cheek skin and bone, mandibular ankylosis and craniofacial dismorphisms, and the modern approach in reconstructive microsurgery. The authors report a case of a patient affected by Noma, with a very evident left face dismorphism, where we found a brilliant solution using a left radial forearm fasciocutaneous free flap, appropriately shaped.

Abstract
Orthodontic expansion of the maxilla can be facilitated by bone cuts through the zygomatic-alveolar process and in the palate lateral of the nasal septum. Stability of the surgical-orthodontic treatment outcome depends on the equilibrium of forces of the tongue and cheeks (functional envelope). Long term, even lifetime, retention is advised.

Abstract
Noma, or cancrum oris, has been described as a gangrenous infection of the soft and hard tissues of the oronasal region. Prior to the advent of antibiotics the disease was commonly fatal. Now many survive the acute phase of the disease and present the surgeon with formidable problems of repair. This is a report of a presumed case of noma that resulted in bony ankylosis of the maxilla and mandible. Three-dimensional shaded surface CT reconstruction images were especially useful in demonstrating the architecture of the abnormal bone.

Abstract
In the acute stage of noma the role of surgery is a minor one: wound care and, very occasionally, treatment of haemorrhage. However in patients who survive noma, and develop a mutilated and disabled face (trismus, leakage of saliva, impaired speech), reconstructive surgery may improve their fate significantly. Because of economic and educational reasons reconstructive surgery in noma patients should be performed preferably in their own country. Treatment consists of excision of all scar tissue, correction of the trismus and closure of the tissue defects with local, pedicled or free flaps. Because of the large variety of tissue defects and the many surgical options, systematization and subsequently standardization of the reconstructive surgical approach to patients with the sequelae of noma is needed.

Abstract
Humanitarian plastic surgery missions are often a substitute, as plastic surgery training missions are essential for the development of plastic surgery in developing countries. This training must be progressive and adapted to the country's needs. Several simple plastic surgery techniques are sufficient to treat a large number of patients: split-skin grafts, full-thickness skin grafts, Z-plasties, latissimus dorsi myocutaneous pedicle flap.

Abstract
PURPOSE To report successful awake insertion of the intubating laryngeal mask (Fastrach) and subsequent tracheal intubation through it, in a patient with predicted difficult tracheal intubation, due to limited mouth opening, and difficult ventilation through a facemask, due to a large mass at the corner of the mouth. CLINICAL FEATURES A 53-yr-old woman with a large post-gangrenous mass on the right cheek to the angle of the mouth was scheduled for its resection. The right side of her face was damaged by a bomb attack followed by cancrum oris 50 yr ago. The distance between the incisors during maximum mouth opening was 2 cm and that between the gums on the right side < 1 cm. After preoxygenation and 50 micrograms fentanyl and 30 mg propofol i.v., propofol was infused at 2 mg.kg-1.hr-1. Lidocaine, 8%, was sprayed on the oropharynx. A #4 intubating laryngeal mask was inserted with a little difficulty. A fibrescope was passed through a 7.5-mm ID RAE tracheal tube, and the combination was easily passed through the laryngeal mask into the trachea. General ansthesia was then induced. Finally, the intubating laryngeal mask was removed, while the RAE tube was being stabilized using an uncuffed 6.0-mm ID tracheal tube. CONCLUSION Awake tracheal intubation through the intubating laryngeal mask is a useful technique in patients with limited mouth opening in whom ventilation via a facemask is expected to be difficult.

Abstract
After analysing their concept of humanitarian plastic surgery, the authors present their personal experience which started in the 1970s, concerning two aspects: in the field (Burkina-Faso, Mali, Niger) and in Geneva, Switzerland, where the more difficult cases are operated. They illustrate their approach by a clinical case of sequelae of noma. They analyse the problems and/or questions raised by humanitarian plastic surgery: sufficient training, choice of surgical techniques, postoperative follow-up, assessment of the results obtained, possible innovations.

Abstract
Acquired large nasal defects are much more common in adulthood than in childhood because of the frequency of skin tumors after a certain age. However, from their experience in treating a number of children with sequelae of noma and burns, the authors have collected a series of 17 total and 12 partial nasal reconstructions in children aged 1 to 15 years. After reviewing the various methods used for recreating the lining, the support, and the skin cover in the whole series, three cases are reported in detail. A 1-year-old patient received a tempororetroauricular flap after total amputation of the nose and was observed for 17 years. Another patient, who was burned as a baby, underwent reconstruction at age 10 with a deltopectoral flap and was observed for 7 years. The third patient underwent total nose reconstruction at age 12 with an Indian forehead flap. From their experience, the authors conclude that, for psychosocial reasons, nasal reconstruction should be started early, despite possible reoperation at a later age. The best results are certainly obtained at the end of growth or at least after the age of 12. Adjacent bone or soft tissue defects further enhance the difficult challenge of restoring a satisfactory aesthetic appearance in these children.

Abstract
Recurrent parotid abscess formation as a consequence of isolated right parotid duct osteal stenosis was a very unusual sequela of successfully treated early cancrum oris. Interestingly, it manifested after an uneventful interval of 8 years and required a near-total conservative parotidectomy for cure.

Abstract
Cancrum oris cases are occasionally treated in various hospitals in Kenya. Despite this, only one case has been reported in literature. Besides, no epidemiological or treatment studies of cancrum oris has been carried out in Kenya. We report an unusual case of a 17 year old Kenyan female with oral cutaneous fistula and tissue atrophy on the left cheek following cancrum oris infection in childhood. Since most cancrum oris cases are a sequela of acute necrotizing gingivitis (ANG), prevention of cancrum oris can be achieved by early and prompt remedial measures once a diagnosis of ANG is established. Failure to do this might lead to cancrum oris with its attendant disfiguring complications some of which might be impossible to treat in developing countries where the requisite personnel is lacking or inadequate.

Abstract
The surgical treatment of the sequelae in the patients affected by noma is possible even in emerging countries if the surgeon carefully evaluates each patient individually choosing simple, safe, sound and satisfactory techniques which are conditioned by sex and age of the patients. Two cases of sequelae treated with different techniques are described.

Abstract
Noma is a very rare gangrenous infection of the oral cavity usually associated with debilitating diseases, immunosuppression, or malnutrition. Its development in a previously healthy 13-year-old boy with perforated appendicitis is presented. Streptococcus bovis type II and E coli were isolated from the noma and Streptococcus bovis, Bacteroides fragilis, and Bacteroides asacharolyticus from the peritoneal fluid. A transient impaired immune cellular function was found and may have contributed to the development of the noma in this child.
