Cervical necrotizing fasciitis caused by oral cavity infection: a case report considering therapeutic approach and its morphofunctional implications / Fascitis necrosante cervical causada por infección de la cavidad oral. Reporte de un caso considerando el abordaje terapéutico y sus implicaciones morfofuncionales

SUMMARY: Cervical necrotizing fasciitis (NF) is a rare complication of oral cavity infection with high morbi-mortality. Given its low prevalence, adequately reporting cases of NF, its therapeutic management, and associated morphofunctional modifications to the clinical and scientific community is pivotal. To that end, we herein describe a case of cervical NF in a 60-year-old patient with comorbidities and patient presented large, painful cervical swelling associated with a necrotic ulcer lesion in the anterior neck region. Intraoral examination indicated a periodontal abscess in the right mandibular area, while computed tomography indicated the lesion's extension from the right mandibular to the submandibular region. Following empirical intravenous antibiotic treatment, a broad surgical debridement was performed, and the foci of oral infection were removed. Debridement revealed communication between deep and superficial anatomical regions in the submandibular area, where we subsequently placed a Penrose drain. Biopsies showing acute inflammatory infiltrate associated with necrotic and hemorrhagic regions confirmed the diagnosis of NF. When an antibiogram revealed resistance to the empirical treatment, the antibiotic scheme was replaced with an adequate alternative. After a second debridement, we closed the defect with fascio-mucocutaneous advancement flaps with a lateral base while maintaining suction drainage. Having reacted positively, the patient was discharged 10 days after the operation. Despite an extensive morphofunctional change generated in the treated area, the patient showed no difficulties with breathing, phonation, swallowing, or mobilizing the area during control sessions. Altogether, this report contributes to the highly limited literature describing morphological aspects that can facilitate or delay the spread of infection or the morphofunctional disorders associated with the size and depth of surgical interventions for cervical NF, information that is relevant for the comprehensive, long-term prognosis of the treatment of NF.

La fascitis necrosante (FN) cervical es una rara complicación de una infección proveniente de la cavidad bucal asociada a una alta morbimortalidad. Por lo anterior, es fundamental informar a la comunidad clínica y científica los casos de FN, su manejo terapéutico y las modificaciones morfofuncionales asociadas. Se describe un caso de FN cervical en una paciente de 60 años quien presentó una gran tumefacción dolorosa asociada a una lesión ulcerosa necrótica en la región anterior del cuello. El examen intraoral mostró un absceso periodontal en el área mandibular derecha y la tomografía computarizada mostró la extensión de la lesión hacia la región submandibular. Tras el tratamiento antibiótico empírico, se realizó un desbridamiento quirúrgico extenso y se extirparon los focos de infección oral. El desbridamiento reveló comunicación entre las regiones anatómicas profundas y superficiales del área submandibular, donde se colocó un drenaje Penrose. Las biopsias mostraron un infiltrado inflamatorio agudo asociado con regiones necróticas y hemorrágicas, confirmando el diagnóstico de FN. El antibiograma reveló resistencia al tratamiento empírico, por lo que el esquema antibiótico se sustituyó. Tras un segundo desbridamiento, se cerró el defecto con colgajos de avance fascio-mucocutáneos de base lateral manteniendo drenaje aspirativo. El positivo progreso del paciente permitió su alta 10 días después. Aun cuando se generó una gran modificación morfofuncional en el área tratada, la paciente no presentó dificultades para respirar, hablar, deglutir o movilizar el área cervical intervenida durante las sesiones de control. Este informe contribuye a la limitada literatura que describe los aspectos morfológicos que pueden facilitar o retrasar la propagación de la FN y las consecuencias asociadas a los trastornos morfofuncionales provocadas por el tamaño y profundidad de las intervenciones quirúrgicas requeridas por la FN, información relevante para el pronóstico integral a largo plazo del tratamiento de la FN.

INTRODUCTION: Necrotizing soft tissue infection (NSTI) has a high morbidity and mortality. The objective of this study is to describe the perioperative management of children under 15 years of age who have had this condition for 15 years in a pediatric hospital. MATERIAL AND METHODS: cases series of patients identified by Pathological Anatomy with NSTI during 2000 and 2015 at the Dr. Roberto del Río Hospital. Demographic variables, treatment, antecedents of vaccination, surgeries, complications, microorganisms, follow-up, and deaths are described. RESULTS: 22 patients were identified, with a median of 2 years 9 months of age (interquartile range: 13 months to 5 years y 10 months). 50% of the cases were associated to chickenpox. Two died. No patient was previously vaccinated against varicella zoster virus. The location was trunk (14), extremities (7) and neck (1). All conscious patients presented cutaneous hyperesthesia. Surgical debridement was performed with a median of 6.8 hours from the onset of hyperesthesia and 2 hours from diagnostic suspicion. The most frequent microorganisms were: Streptococcus pyogenes (38%) and Escherichia coli (31%). The most frequent antibiotics used were penicillin plus clindamycin. The wound was handled with primary closure, grafts and / or flaps. Five patients evolved with sequelae that needed treatment. CONCLUSION: It was identified that STNI in children is associated with chickenpox. It should be suspected in cutaneous lesions and disproportionate hyperesthesia. Aggressive resection is essential for treatment

Fascitis necrotizante como complicación de apendicitis aguda: a propósito de un caso / Necrotizing fasciitis as a complication of acute appendicitis: a case report

La Fascitis necrotizante (FN) es una infección aguda del tejido subcutáneo que puede comprometer la fascia y producir compromiso sistémico y sepsis. Es una complicación extremadamente rara posterior a una apendicitis aguda. Objetivo: Demostrar la importancia de realizar el diagnóstico a tiempo y la intervención de forma precoz. Caso clínico: Presentamos el caso de un paciente que evoluciona con una Fascitis necrotizante posterior a una apendicectomía. Se realiza una intervención quirúrgica y terapia antimicrobiana precoz, con una favorable evolución. Conclusiones: La FN es una patología con escasa sintomatología y signología clínica, por lo que se debe tener un alto grado de sospecha. Un diagnóstico e intervención a tiempo logra mejorar la sobrevida de los pacientes.

Necrotizing fasciitis is characterized by a necrotic infection that rapidly spreads along the fascia and progresses to systemic sepsis. A fatal complication of acute appendicitis is extremely rare. Objective: Ilustrates the importance of early diagnosis and prompt surgical intervention. Case Report: We present a case of necrotizing fasciitis after an appendicectomy. An early intervention and antibiotic therapy allowed a favorable evolution. Conclusions: The necrotizing fasciitis has a nonspecific symptomatology and signology, so we must suspect the patology. An early diagnosis and aggressive surgical intervention can be life- saving.

Atypical presentation of cervical necrotizing fasciitis: case report

Cervical necrotizing fasciitis (NF) is a soft tissue infection with a low incidence, characterized by rapid progression and high morbidity and mortality. The purpose of this report is to communicate the case of a patient diagnosed with cervical NF and its successful management. A 54-year-old male consulted after suffering from the condition for seven days. It was characterized by bilateral submandibular swelling, accompanied by fever, dysphagia, odynophagia, which were severely affecting the patient's general health. Physical examination revealed a painful, erythematous cervical swelling. A cervical computed tomography scan was performed, revealing a gaseous collection in the left mucosal pharyngeal space, extending to the glottis, associated with significant deep plane soft tissue emphysema onon the left side of the neck and with possible involvement of the danger space; pertinent lab findings include 19,190/uL leukocytes and 219mg/L CRP. Broad-spectrum antibiotic therapy was initiated with ceftriaxone and clindamycin. Exploratory surgery, lavage and drainage of the collected material were performed. Streptococcus anginosus was isolated by culture. The patient recovered appropriately showing improvement in clinical as well as in inflammatory parameters, being discharged on the ninth day. He is currently receiving periodical checkups in the surgery polyclinic

Necrotizing fasciitis: eight-year experience and literature review

OBJECTIVES: To describe clinical, laboratory, microbiological features, and outcomes of necrotizing fasciitis. METHODS: From January 1, 2004 to December 31, 2011, 115 patients (79 males, 36 females) diagnosed with necrotizing fasciitis were admitted to Mackay Memorial Hospital in Taitung. Demographic data, clinical features, location of infection, type of comorbidities, microbiology and laboratory results, and outcomes of patients were retrospectively analyzed. RESULTS: Among 115 cases, 91 survived (79.1%) and 24 died (20.9%). There were 67 males (73.6%) and 24 females (26.4%) with a median age of 54 years (inter-quartile ranges, 44.0-68.0 years) in the survival group; and 12 males (50%) and 12 females (50%) with a median age of 61 years (inter-quartile ranges, 55.5-71.5 years) in the non-surviving group. The most common symptoms were local swelling/erythema, fever, pain/tenderness in 92 (80%), 87 (76%) and 84 (73%) patients, respectively. The most common comorbidies were liver cirrhosis in 54 patients (47%) and diabetes mellitus in 45 patients (39%). A single organism was identified in 70 patients (61%), multiple pathogens were isolated in 20 patients (17%), and no microorganism was identified in 30 patients (26%). The significant risk factors were gender, hospital length of stay, and albumin level. DISCUSSION: Necrotizing fasciitis, although not common, can cause notable rates of morbidity and mortality. It is important to have a high index of suspicion and increase awareness in view of the paucity of specific cutaneous findings early in the course of the disease. Prompt diagnosis and early operative debridement with adequate antibiotics are vital. .

Ocular necrotizing fasciitis due to Pseudomonas aeruginosa in a non-neutropenic patient

Eyelid necrosis is a very rare disease, usually secondary to trauma or infections. Pseudomonas aeruginosa [PA] eyelid necrosis remains principally a clinical diagnosis and it is often missed early in its presentation because of the difficulty in differentiating it from more common soft tissue infections. However, when the diagnosis is made we must act quickly due to the fatal evolution if not handled properly. We present the case of a non-neutropenic 53-year-old male patient with a history of alcoholism, smoking habit and lung cancer under chemotherapy treatment who developed ocular necrotizing fasciitis due to PA with perforation of his left eye and severe bilateral sclera ischemia despite intensive antibiotic treatment and surgical debridement.

Primary Shewanella algae Bacteremia Mimicking Vibrio Septicemia

Shewanella algae infections are rare in humans. Previously reported cases of S. algae have mainly been associated with direct contact with seawater. We report a case of primary S. algae bacteremia occurring after the ingestion of raw seafood in a patient with liver cirrhosis that presented a fulminent course of necrotizing fasciitis.

Founrnier's gangrene: review of thirteen cases

Founrnier's gangrene is a synergistic necrotizing fascitis of the perineum and external genitalia. The process was belived to be idiopathic in initial descriptions. Thirteen patients were treated from Fournier's gangrene between 2000 and 2006 in the departments of surgery in El Helal and General Transport Organization hospitals. The common predisposing factors in all our cases were uncontrolled diabetes and sever anaemia. Escherichia coli and Sterptococcus aureus were identified most commonly in cultures of necrotic tissues. Our strategy in management of these cases was simultaneous control of the bad general condition of the patients with serial depridment of the necrotic tissues. Reconstructive operations to cover the raw areas were delayed till complete improvement of the medical status of the patients and till the affected areas were covered by healthy granulation tissues. There was no mortality among our cases

Cutaneous melioidosis and necrotizing fasciitis with pulmonary involvement in a chicken seller.

Melioidosis is endemic in Malaysia. Cutaneous melioidosis is one manifestation and it may progress to necrotizing fasciitis. The case highlights a 46-year-old male, a chicken-seller who presented with scalp cellulitis which later progressed to necrotizing fasciitis and pneumonia are presented here. It illustrates several key features of the presentation, prompt laboratory diagnosis and early treatment of melioidosis which saved the patient's life.

Mortality in necrotizing fasciitis

The objective of this study was to determine the mortality rate in patients presenting with Necrotizing Fasciitis. This prospective study was conducted at ward 26, JPMC Karachi over a period of two years from March 2001 to Feb 2003. All patients above the age of 12 years diagnosed to be having Necrotizing Fasciitis and admitted through the Accident and emergency department were included in this study. After resuscitation, the patients underwent the emergency exploration and aggressive surgical debridement. Post-operatively, the patients were managed in isolated section of the ward. The patients requiring grafting were referred to plastic surgery unit. The patients were followed up in outpatients department for about two years. Over all, 25 male and 5 female patients fulfilled the inclusion criteria and were included in this study. The common clinical manifestations include redness, swelling, discharging abscess, pain, fever, skin necrosis and foul smelling discharge etc. The most common predisposing factor was Diabetes mellitus whereas the most commonly involved site was perineum. All patients underwent aggressive and extensive surgical debridements. The common additional procedures included Skin grafting, Secondary suturing, Cystostomy and Orchidectomy. Bacteroides and E. coli were the main micro-organisms isolated in this study. Bacteroides was the most common microorganism isolated among the eight patients who died. Necrotizing Fasciitis is a potentially life threatening emergency condition and carries the mortality rate of about 26.6%. The major contributing factors to increase the mortality missed initially diagnosed, old age, diabetes mellitus truncal involvement and late presentation. Anorectal involvement of disease carry worse prognosis. Hyperbaric oxygen therapy and proper use of unprocessed honey reduced the mortality rate

Fascitis necrosante grave por Serratia marcescens: Reporte de un caso clínico / Fatal necrotizing fasciitis due to Serratia marcescens

Una paciente de 81 años con insuficiencia cardíaca crónica, fibrilación auricular y tratamiento anticoagulante, ingresó por un cuadro fulminante de dolor y celulitis en la extremidad inferior derecha de 24 horas de evolución. Sobre la zona existía una úlcera crónica de cinco meses de evolución, manejada con curaciones locales. Al ingreso, había una placa necrótica pero sin hipotensión o confusión mental. La paciente estaba febril y con taquicardia (126 por min). La evaluación reveló ausencia de leucocitosis, trombosis venosa profunda en la misma pierna e infiltrados radiológicos pulmonares en el lóbulo inferior izquierdo. En las horas siguientes aumentó el dolor, apareció secreción purulenta por la úlcera y la paciente presentó confusión, hipotensión, falla respiratoria y luego shock. La paciente recibió ciprofloxacino endovenoso y clindamicina y fue intervenida a las 15 horas de ingreso, efectuándose una amputación supracondílea. El sondeo cardíaco demostró un gasto bajo (2,3 L/min) y una resistencia vascular sistémica (2888 din.s.cm"5) y presión capilar pulmonar elevada (17 cm H(2)0), cifras compatibles con un shock cardiogénico. Evolucionó en malas condiciones y falleció de falla orgánica múltiple a las 36 horas de ingreso. Los hemocultivos demostraron crecimiento de Serratia marcescens en dos frascos. No se efectuó una necropsia y los cultivos de la secreción de la úlcera fueron negativos.

An 81 year old female patient with chronic heart failure and atrial fibrillation receiving anticoagulant therapy, was admitted with progressive pain on her right leg for the past 24 hours, associated to local erythema, edema and warmth. The lesion evolved at the same site where she presented a chronic ulcer for the previous 5 months managed only with local care. At admission a necrotic plaque on the affected site was perceived; there was no hypotension or mental confusion but signs of a deep venous thrombosis on the involved leg were found. She was febrile (37.8°C) and with tachychardia (126 per minute). Laboratory evaluation revealed normal white blood cell count and a subtherapheutic anticoagulant INR value. A chest x-ray showed infiltrates on the left lower lung lobe. On the following hours the lesion evolved with increasing pain, haemorrhagic bullae and a purulent discharge through the ulcer, with the patient developing mental deterioration, hypotension, respiratory failure and shock. The patient received intravenous ciprofloxacin and clindamycin and was operated 15 hours after admission performing an over-the knee amputation. A cardiac catheterization demonstrated a low cardiac output (2.3 L/min), and both a high systemic vascular resistance (2888 din.s.cm"5) and pulmonary capillary wedge pressure (17 cm H(2)0), results compatible with cardiogenic shock. Evolution was progressively worse and she died of multiple organic failure 36 hours after admission. Two blood culture samples grew Serratia marcescens. No necropsy was performed and cultures taken from the leg remained negative.

Cutaneous zygomycosis: necrotising fascitis due to Saksenaea vasiformis.

Saksenaea vasiformis is an emerging human pathogen, most often associated with cutaneous or subcutaneous lesions following trauma. This is the report of a case of subcutaneous zygomycosis from which Saksenaea vasiformis was isolated on culture. As the patient developed acute interstitial nephritis, amphotericin B could not be administered in full dose. Surgical debridement was carried out, but the patient deteriorated gradually and died. To the best of our knowledge, this is the first reported case of Zygomycosis due to Saksenaea vasiformis from Visakhapatnam.

Fasceitis necrotizante: presentación de un caso y revisión del tema / Necrotizing fasciitis: a case presentation and subject review

La fasceitis necrotizante es la infección y posterior destrucción del tejido adiposo subcutáneo y de la fascia subyacente. Es una enfermedad infrecuente, pero con gran mortalidad asociada. Es de etiología bacteriana, mayormente polimicrobiana. Existen múltiples factores de riesgo asociados al desarrollo de una presentación invasiva de esta enfermedad. Las manifestaciones clínicas en la etapa inicial no son categóricas de esta patología, por lo cual se tiende a confundir con la celulitis y erisipela. De esta manera, la sospecha clínica inicial es fundamental para iniciar el manejo oportuno de los pacientes. Los pilares del tratamiento son la cirugía y el tratamiento antibiótico, que deben ser iniciados precozmente para lograr un pronóstico favorable. Existen otros tratamientos, como el uso de oxígeno hiperbárico y la administración endovenosa de inmunoglobulina, pero la evidencia no es suficiente para apoyar su uso de rutina. Se presenta un caso clínico de esta patología.

Cervical necrotizing fasciitis due to bacterial tonsillitis

A fasceite necrotizante cervical é uma infecção grave de partes moles do pescoço. Trata-se de entidade rara, porém quando presente tem como principal origem um foco infeccioso odontogênico. São descritos 4 casos de fasceite necrotizante cervical a partir de tonsilites e abscesso peritonsilar, os quais, foram admitidos e tratados na unidade de terapia intensiva. Um dos pacientes era portador de Diabetes Melittus não insulino- dependente e outro paciente havia recebido corticoterapia antes do desenvolvimento da infecção. Em um dos casos ocorreu mediastinite, insuficiência respiratória e o paciente evolui para o óbito em decorrência de choque séptico. Durante o tratamento, 3 pacientes evoluíram satisfatoriamente devido ao diagnostico precoce, tratamento cirúrgico agressivo e utilização de antibiótico terapia de largo espectro. A bactéria mais comumente encontrada foi o Streptococcus sp, mas flora mista com germes anaeróbios foi encontrada em 3 dos casos descritos. CONCLUSÕES: Deve-se suspeitar de tonsilite e abscesso peritonsilar como causa de fasceite necrotizante cervical para que tratamento agressivo e precoce seja realizado.

Treatment of necrotizing fasciitis with quinolones

To evaluate the effect of high dose quinolones therapy in patients with necrotizing fasciitis. Design: descriptive analytical study. Place and Duration of Study: the department of Plastic and reconstructive surgery, Hayatabad Medical complex, Peshawar, from January 2001 to March 2002. Subjects and Twenty consecutive patients, diagnosed with necrotizing fasciitis, were treated with intravenous quinolones [400 mg 8 hourly]. The response was evaluated in terms of subsidence of fever and C-reactive proteins levels. Majority of the patients was male [60%]. Lower limb involvement was most commonly involved [70%]. The most common initiating cause was injection abscess [45%]. Majority of the cultures showed polymicrobial infection [90%]. The most common isolate was streptococcus pyogenes [65%]. Majority of the patients showed excellent response with intravenous quinolones [Ciprofloxacin] in high doses in 24-48 hours. Only two patients [10%] failed to respond to therapy due to severe infection and delay in seeking treatment. Intravenous quinolones [Ciprofloxacin] in high doses are effective in controlling necrotizing soft tissue infections

Necrotizing fasciitis: management and outcome

To observe the various clinical presentations of necrotizing fasciitis and evaluate their management and outcome. Design: An observational descriptive study. Place and Duration of Study: Surgical-C Unit of Khyber Teaching Hospital, Peshawar, from July 2001 to June 2002. Subjects and The study included 20 patients of necrotizing fasciitis treated during this period. Age, gender, clinical presentation and predisposing factors were recorded. Pus was cultured and the isolated organism and their sensitivity identified. Management included broad-spectrum antibiotics, extensive and frequent debridements along with supportive measures. Common age group was 21-40 years with a male predominance. Eight patients had necrotizing fasciitis of inguinoscrotal and perineal region, while 6 each had abdomen and 6 with necrotizing fasciitis of the limbs involvement. Factors predisposing to infection were diabetes in 5 patients, abscess in 6, trauma in 3 and surgery in 3 patients, while no specific cause was found in 3 cases. Escherichia [E. coli], Bacteroids, Enterococci and Streptococci were the commonest organisms isolated. All were sensitive to a combination of piperacillin and ampicillin. Debridements were done 1-5 times in most cases. Fifteen patients [75%] had complete recovery, 2 [10%] went to other hospitals on their own, 2 [10%] patients expired while one patient was referred to the plastic surgery unit. Necrotizing fasciitis has multiple etiology and predisposing factors. The bacteriology is poly microbial. Early presentation and diagnosis, supportive measures, broad-spectrum antibiotics, prompt and aggressive surgical debridements remains the cornerstone of management

Necrotizing fasciitis in a newborn infant: a case report

We report the case of a one-day-old newborn infant, female, birth weight 1900 g, gestational age 36 weeks presenting with necrotizing fasciitis caused by E. coli and Morganella morganii. The newborn was allowed to fall into the toilet bowl during a domestic delivery. The initial lesion was observed at 24 hours of life on the left leg at the site of the venipuncture for the administration of hypertonic glucose solution. Despite early treatment, a rapid progression occurred resulting in a fatal outcome. We call attention to the risk presented by this serious complication in newborns with a contaminated delivery, and highlight the site of the lesion and causal agents

Infecciones severas de partes blandas / Soft tissue infections

Antecedentes: Las infecciones severas de partes blandas, son cuadros rápidamente progresivos. Su reconocimiento tardío conspira contra las posibilidades de curación. Objetivo: Analizar un grupo de pacientes atendidos en los últimos siete años. Evaluamos factores predisponentes y determinantes como así también el tratamiento. Método: Fueron analizados 29 pacientes que presentaron infecciones severas de partes blandas y divididos según la variedad anatomoquirúrgica de presentación. Resultados: La mortalidad global fue de 11 pacientes (37,9 por ciento). Las lesiones por clostridio presentaron 100 por ciento de mortalidad. La Cámara Hiperbárica fue utilizada en seis pacientes de los cuales cuatro fallecieron. Conclusiones: Son afecciones que deben sospecharse en forma específica, en enfermos con factores predisponentes. Los diagnósticos tempranos permiten mejor evolución. Los debridamientos deben ser amplios y reiterados

Infecciones de tejidos blandos / Soft tissue infections

Se revisan 20 casos de infecciones de tejidos blandos hospitalizados en el Servicio de Cirugía del Hospital San Juan de Dios (1990-1998). De estos, 10 correspondieron a fasceítis, 9 a celulitis y 1 caso de erisipela. La etiología fue predominantemente polimicrobiana en la fasceítis necrotizante (80 por ciento) y monomicrobiana en la celulitis (55 por ciento). La evolución clínica fue favorable en el 100 por ciento de los casos de erisipela y celulitis, los cuales requirieron solamente tratamiento antimicrobiano. Falleció el 20 por ciento de los pacientes con fasceítis necrotizante y otro debió ser sometido a amputación. El tratamiento de estos casos es fundamentalmente quirúrgico, asociado a terapia antimicrobiana
