Celulitis facial por Staphylococcus aureus con metástasis infecciosas y evolución tórpida. Caso pediátrico / Facial cellulitis due to Staphylococcus aureus with metastatic infection and torpid course. A pediatric case report

La bacteriemia por Staphylococcus aureus se define como el aislamiento de dicho germen en al menos un cultivo de sangre. Las metástasis infecciosas se originan por diseminación hematógena y su posterior localización en un sitio distinto al órgano en donde se originó el proceso infeccioso. La prevalencia en la presentación de estos focos infecciosos secundarios es baja en la edad pediátrica, por lo que representa un desafío diagnóstico. Se presenta el caso de un paciente pediátrico con una celulitis facial por Staphylococcus aureus, con metástasis infecciosas y evolución tórpida.

Bacteremia due to Staphylococcus aureus is defined as the isolation of this microorganism in at least one blood culture. A metastatic infection is caused by the hematogenous dissemination and subsequent location of the microorganism in a site other than the one where the infection started. The prevalence of these secondary sources of infection is low in the pediatric population, which is a diagnostic challenge. Here we describe the case of a pediatric patient with facial cellulitis due to Staphylococcus aureus, with metastatic infection and torpid course.

Síndrome celulitis-adenitis, una forma infrecuente de presentación de la sepsis neonatal tardía: A propósito de dos casos / Adenitis-cellulitis syndrome, an infrequent form of presentation of the late-onset neonatal septicemia: Report of two cases

La sepsis es la principal causa de mortalidad neonatal. La forma precoz, habitualmente, está relacionada con la colonización recto-vaginal u otros factores de riesgo materno. En la forma tardía, es difícil establecer su origen; por lo general, es nosocomial o de la comunidad. El Streptococcus agalactiae (Streptococcus beta-hemolítico del grupo B) es el germen implicado con más frecuencia en la sepsis neonatal en países desarrollados. La forma tardía, generalmente, se presenta con septicemia y meningitis, y, en ocasiones, pueden detectarse infecciones osteoarticulares o de piel y tejidos blandos. El síndrome celulitis-adenitis en la región cervical, forma poco frecuente de presentación, es causado por Staphylococcus aureus y, ocasionalmente, por Streptococcus agalactiae. Se reportan 2 casos de sepsis neonatal tardía con clínica de celulitis-adenitis cervical causados por Streptococcus beta-hemolítico del grupo B, con una evolución satisfactoria con terapia antibiótica de amplio espectro.

Septicemia is the main cause of neonatal mortality. The early-onset neonatal sepsis is usually related to maternal factor risks including recto-vaginal colonization. In the late-onset neonatal septicemia it is more difficult to establish the etiology because the majority of the cases are nosocomial or community related. The Streptococcus agalactiae (beta-hemolytic Streptococcus) is the most frequent germ associated with neonatal sepsis in developed countries. The late-onset form usually occurs with septic symptoms and meningitis and, in a few cases, with osteoarticular, skin and soft tissue infection. Adenitis-cellulitis syndrome is rarely seen, and its main cause is Staphylococcus aureus, followed by Streptococcus agalactiae. We report two cases of group B Streptococcus late-onset neonatal septicemia, both of them with adenitis-cellulitis syndrome. Patients recovered uneventfully after an adequate antibiotic therapy.

Education-family physician corner eosinophilic cellulitis [wells syndrome]

Eosinophilic Cellulitis [Wells Syndrome] is an uncommon inflammatory disease with clinical polymorphism. A thirty-five-year-old female presented with 2 weeks history of gradually progressive and painful erythematous plaque on the right foot. She had already received several types of antibiotic for the Cellulitis without improvement. A diagnosis of Wells syndrome was established. Significant improvement was noted after one month of treatment with prednisolone. Awareness of this condition is necessary for early identification and management

Extensive cervical lymphadenitis mimicking bacterial adenitis as the first presentation of Kawasaki disease / Extensa linfadenite cervical mimetizando adenite bacteriana como primeira manifestação da doença de Kawasaki

Cervical adenitis >1.5cm in diameter is the less frequently observed criteria in patients with Kawasaki disease and it is usually found in association with other symptoms during the acute phase. Moreover, the finding of fever and lymphadenitis with intense local signs of inflammation and phlegmon is rarely seen as the initial manifestation of Kawasaki disease. We report the case of a 7-year-old boy who had cervical lymphadenitis with adjacent cellulitis and phlegmon mimicking bacterial adenitis as the first presentation of Kawasaki disease. The patient had fever, cervical lymphadenitis with adjacent cellulitis, and severe headache. Cefadroxil was prescribed based on the clinical diagnosis of bacterial adenitis. Because he remained febrile and phlogistic signs worsened, after 1 day of hospitalization, antibiotics were administrated intravenously (ceftriaxone and oxacillin). The computed tomography of the neck showed primary infectious/inflammatory process. On the fourth day, the patient had dry and scaly lips, and treatment with oxacillin was replaced by clindamycin because the patient was still febrile. On the ninth day, he presented non-exudative bilateral conjunctival injection. On the tenth day of febrile disease, a rash appeared on his trunk, hands and feet. Patient’s symptoms resolved after intravenous administration of immunoglobulin (2g/kg/dose), and he was discharged 2 days later. On the 14th day, the patient had lamellar desquamation of fingers. Kawasaki disease should be considered as a differential diagnosis in children with febrile cervical lymphadenitis unresponsive to empiric antibiotics even if they have adjacent cellulitis and phlegmon.

Adenite cervical >1,5cm é o critério menos frequentemente observado em pacientes com doença de Kawasaki e manifesta-se habitualmente em associação com os demais sintomas da fase aguda. Entretanto, linfadenite febril isolada com intensos sinais flogísticos e flegmão é raramente observada como primeira manifestação da doença de Kawasaki. Assim, relatou-se aqui um caso de uma criança que apresentou linfadenite cervical com celulite adjacente e flegmão mimetizando adenite bacteriana como primeira manifestação da doença de Kawasaki. Paciente previamente hígido, 7 anos, masculino, iniciou quadro de febre, adenite cervical com celulite adjacente e cefaleia intensa, sendo prescrita cefadroxila devido ao diagnóstico clínico de linfadenite bacteriana. Por se manter febril e com piora dos sinais flogísticos, após 1 dia foi internado para receber antibioticoterapia endovenosa (oxacilina e ceftriaxona). Tomografia computadorizada da região cervical mostrou processo infeccioso/inflamatório primário. No quarto dia, apresentou lábios ressecados e descamativos, sendo a oxacilina substituída por clindamicina devido à persistência da febre e sinais flogísticos. No nono dia, iniciou hiperemia ocular não exsudativa. No décimo dia de febre, apresentou exantema em tronco, membros, mãos e pés. Recebeu gamaglobulina endovenosa (2g/kg/dose), evoluiu com resolução dos sintomas e, após 2 dias, recebeu alta hospitalar. No 14odia, apresentou descamação lamelar dos dedos das mãos. Portanto, doença de Kawasaki deve ser considerada no diagnóstico diferencial das linfadenites cervicais febris na infância não responsivas à antibioticoterapia empírica, mesmo que esteja presentes celulite adjacente e flegmão.

Leprosy type-I reaction episode mimicking facial cellulitis-the importance of early diagnosis

Leprosy is aneasily recognizable disease due to its dermato-neurological manifestations. It must be present in the physician’s diagnostic repertoire, especially for those working in endemic areas. However, leprosy reaction is not always easily recognized by non-dermatologists, becoming one of the major problems in the management of patients with leprosy, as it presents clinical complications characterized by inflammatory process, accompanied by pain, malaise and sometimes the establishment or worsening of the patient’s disabilities. We report the case of a patient with type-1 periorbital reaction admitted to the hospital, diagnosed and treated as facial cellulitis, whose late diagnosis may have contributed to the appearance or worsening of facial neuritis.

OBJETIVO: Investigar as complicações orbitais em crianças e adultos com sinusite. MÉTODO: Os pacientes que frequentam clínica de Otorrinolaringologia com sinusite de janeiro de 2010 até janeiro de 2012 foram incluídos. Os pacientes foram classificados em dois grupos, de acordo com sua idade. O primeiro incluiu crianças idade inferior a 16 anos e, o segundo, pacientes com mais de 16 anos. Quadro clínico, seio envolvido, gestão e resultados foram comparados. RESULTADOS: O número total de pacientes foi 616. Complicações orbitais foram observadas em 36 pacientes (5,8%). Destes, 26 pacientes (72,2%) eram crianças (21 tinham presseptal e cinco tiveram celulite orbitária) e dez pacientes (27,8%) eram adultos (cinco com pré-septal, três com celulite orbitária e dois com abscesso). A complicação mais comum foi celulite orbital presseptal (72,2%), seguida de celulite e abcesso orbital (22,2% e 5,6%, respectivamente). O seio mais comum envolvido foi etmoidal em crianças e sinusopatia mista em adultos. A maioria dos pacientes respondeu ao tratamento médico. CONCLUSÃO: As complicações orbitárias da sinusite são mais comuns em crianças do que em adultos e têm prognóstico favorável. .

OBJECTIVE: To investigate orbital complications in children and adult with sinusitis. METHOD: Patients attending ENT clinic with sinusitis from January 2010 until January 2012 were included. Patients were classified into two groups according to their age. First involved children aged less than 16 and second included adults older than 16 years. Clinical picture, sinus involved, management and outcome were compared. RESULTS: The total number of patients were 616. Orbital complications were seen in 36 patients (5.8%). Twenty six patients (72.2%) were children (21 had preseptal and 5 had orbital cellulitis) and ten patients (27.8%) were adults (5 with preseptal, three with orbital cellulitis and 2 with abscess). The most common orbital complication was preseptal cellulitis (72.2%) followed by orbital cellulitis and abscess (22.2% and 5.6% respectively). The commonest sinus involved was ethmoidal in children and mixed sinus pathology in adults. The majority of patients responded to medical treatment. CONCLUSION: Orbital complications of sinusitis are commoner in children than adults and have favorable prognosis. Keywords: Sinusitis, cellulitis, preseptal, abscess. .

Myroides odoratimimus soft tissue infection in an immunocompetent child following a pig bite: case report and literature review

Members of the genus Myroides are aerobic Gram-negative bacteria that are common in environmental sources, but are not components of the normal human microflora. Myroides organisms behave as low-grade opportunistic pathogens, causing infections in severely immunocompromised patients and rarely, in immunocompetent hosts. A case of Myroides odoratimimus cellulitis following a pig bite in an immunocompetent child is presented, and the medical literature on Myroides spp. soft tissue infections is reviewed.

A case of community-acquired Acinetobacter junii-johnsonii cellulitis / Celulitis por Acinetobacter junii-johnsonii adquirida en la comunidad: una presentación de caso

Acinetobacter skin and soft tissue infection outside of the traumatic wound setting are rare occurrences. The majority of cases occur in the presence of significant comorbilities and by Acinetobacter baumanii. Herein a case is reported of community-onset, health-care-associated, non-traumatic cellulitis caused by Acinetobacter, species junii-johnsonii with bacteremia. This is the first reported case of Acinetobacter junii-johnsonii skin and soft tissue infection. Hemorrhagic bullae might be one of the clinical features of Acinetobacter cellulitis.

La infección de piel y tejidos blandos por Acinetobacter no relacionada con trauma es una presentación inusual. La mayoría de los casos descritos presentan enfermedades concomitantes y son causados por Acinetobacter baumanii. Se describe un caso de celulitis no traumática por A. junii-johnsonii con bacteriemia, de inicio en la comunidad y asociado con el tratamiento médico. De acuerdo con nuestro conocimiento, éste sería el primer caso reportado de infección de tejidos blandos y piel por A. junii-johnsonii. La vesícula hemorrágica podría ser una característica clínica de celulitis por Acinetobacter.

Bullae and Sweat Gland Necrosis in the Differential Diagnosis for Vibrio vulnificus Infection in an Alcoholic Patient

Bullae and sweat gland necrosis remain rare cutaneous manifestation, and these conditions can be misdiagnosed as Vibrio vulnificus infections or other soft tissue infections because of their low index of suspicion. A 46-yr-old man with a history of continued alcohol consumption presented with erythematous and hemorrhagic bullous lesions on his left arm. The patient reported that after the ingestion of clams, he slept for 12 hr in a heavily intoxicated state. Then the skin lesions started as a reddish patch that subsequently became hemorrhagic bullae. V. vulnificus infection, cellulitis, and necrotizing fasciitis were considered in initial differential diagnosis. However, on the basis of sweat gland necrosis on histopathologic examinations and negative results on bacterial cultures, we made the diagnosis of bullae and sweat gland necrosis. Therefore, bullae and sweat gland necrosis should also be considered in chronic alcoholic patients who present with bullae and a previous history of unconsciousness.

Corneal Perforation with Preseptal Cellulitis in a Patient with Acute Lymphocytic Leukemia

We report a case of corneal perforation with preseptal cellulitis in a patient with acute lymphocytic leukemia (ALL). A 17-yr-old female patient who was undergoing combination chemotherapy for ALL was referred due to upper lid swelling and pain in the right eye for 2 days. Visual acuity in the right eye was 20/20. Initial examination showed no abnormal findings, other than swelling of the right upper eyelid. Computed tomography showed a finding of preseptal cellulitis. Microbiologic study of bloody and purulent discharge revealed Serratia marcescens. Corneal melting and perforation with iris prolapse were detected in the right eye on the 16th day. Emergent tectonic keratoplasty was performed. Seven months after surgery, visual acuity in the right eye was 20/300, and the corneal graft was stable.

Acute Lymphadenitis with Cellulitis Caused by Staphylococcus lugdunensis / 대한진단검사의학회지

Although coagulase-negative staphylococci (CNS) have been considered part of the resident flora on the human skin, Staphylococcus lugdunensis is an unusually virulent CNS and can cause many types of infection. We report a rare case of acute lymphadenitis with cellulitis in the right infraauricular region caused by S. lugdunensis. A 62-yr-old woman visited the Department of Otolaryngology of Busan Paik university hospital. She had a palpable mass and swelling in the right infraauricular region and complained of aggressive pain and a febrile sensation in the region for 5 days. On the suspicion of abscess with infection, percutaneous aspiration was performed and smooth, flat, white, opaque colonies grew on a blood agar plate as a pure culture. The biochemical test results showed the organism to be catalase positive, tube coagulase negative, ornithine decarboxylase positive, slide coagulase positive, and latex agglutination tests for coagulase positive. The API Staph Kit was used to identify the isolate to the species level as S. lugdunensis with a 64.6% probability (profile 6716152). We confirmed the species identification of this strain by 16S rDNA sequence analysis. The patient's clinical condition improved with appropriate antimicrobial therapy and pus drainage.

Sinusite aguda em crianças: estudo retrospectivo de complicações orbitárias / Acute sinusitis in children: a retrospective study of orbital complications

Das complicações da sinusite, as que envolvem a região orbitária são mais freqüentes. OBJETIVO: Este trabalho tem por objetivo mostrar a incidência de celulite orbitária (CO) como complicação de sinusite aguda em crianças. Forma de Estudo: Retrospectivo. MÉTODO: Após autorização específica, foram avaliados todos os prontuários de pacientes pediátricos, com idade até 12 anos, com diagnóstico de complicação orbitária por sinusite, admitidos na Clínica de ORL e Pediátrica do HPEV no período de 1985 a 2004. Os casos foram analisados segundo o sexo, idade, quadro clínico, seio paranasal acometido, período médio de internação, exames de imagem realizados e tratamento instituído. RESULTADO: No período de 1985 a 2004, foram diagnosticados 25 pacientes portadores de CO, apresentando uma incidência de 6 por cento, predomínio do sexo masculino, com média de idade de 6,5 anos. O seio paranasal mais acometido foi o maxilar. 24 pacientes apresentavam edema periorbitário. Todos os 25 pacientes apresentavam velamento sinusal ao Rx. Um paciente apresentava deslocamento do globo ocular e proptose e a TC mostrava abscesso subperiosteal. O período médio de internação foi de 4 dias. 25 pacientes receberam tratamento antibiótico endovenoso e 2 foram submetidos a tratamento cirúrgico associado. CONCLUSÃO: A incidência de complicações orbitárias pós-sinusite são infreqüentes, com diagnóstico precoce evoluem bem com tratamento clínico. A cirurgia pode ser necessária em alguns casos.

Among the complications of sinusitis, those that involve the orbital region are the most frequent. AIM: the objective of this paper is to show an incidence of orbital cellulites (OC) secondary to acute sinusitis in children. Study design: retrospective. METHODS: After board approval, the charts of all pediatric patients diagnosed with orbital complications secondary to sinusitis, seen at the Pediatric and at the ENT clinics of the HPEV, between 1985 and 2004, were evaluated. The data was analyzed considering gender, age, clinical presentation, period of hospitalization, image study, and treatment. RESULTS: from 1985 to 2004, 25 patients were diagnosed with OC secondary to sinusitis, presenting an incidence of 6 percent . Males predominated, the median age was 6.5 years, and the maxillary was the most frequently involved sinus. Twenty-four patients presented mild peri-orbital swallowing. All 25 patients presented X-Ray alterations. One patient with proptosis had a subperiosteal abcess seen on the CT-scan. The average time of hospitalization was 4 days. All 25 patients received IV antibiotics, 2 required surgery. CONCLUSION: The incidence of orbital complications secondary to sinusitis is low, and although the majority of cases are early diagnosed and respond well to medication treatment, a surgical intervention may be required.

Skin and soft tissue infection.

Abstract. Normal skin is heavily colonized by bacterial flora. The most common are the various nonpathogenic gram-positive bacteria such as Staphylococcus epidermidis (coagulase-negative). Skin and soft tissue infections are usually caused by Staphylococcus aureus (S. aureus) and Streptococcus pyogenes. This article discusses common and some not so common bacterial skin infections, including impetigo, folliculitis, furncles and carbuncles, cellulitis and erysipelas, gangrenous cellulitis, staphylococcal scalded skin syndrome and scarlet fever. Impetigo and ecthyma are common bacterial infections of the skin commonly caused by S. aureus and / or Group A streptoccus. In mild and localized impetigo topical antibiotics whereas in widespread or severe one and in ecthyma systemic antibiotics like, cloxacillin, erythromycin, azithromycin or cephalexin should be used. Folliculitis, furunculosis and carbuncle are folliculocentric infections caused by S. aureus involving the variable depth and extent of the follicle(s) and surrounding tissue. These conditions can be treated with topical or systemic antibiotics like cloxacillin, cephalexin, erythromycin, amoxicillin/clavulanic acid or vancomycin. Staphylococcal scalded skin syndrome is a toxin mediated exfoliative dermatosis caused by S. aureus of phase group II. Intravenous penicillinase-resistant anti-staphylococcal antibiotics like methicillin, cloxacillin, cephalosporin or erythromycin are required. Erysipelas and cellulitis are acute infections of dermal and subcutaneous tissues caused most frequently by Group A beta-hemolytic streptococci (erysipelas) or S. aureus requiring systemic antibiotics like oral or intravenous penicillin, erythromycin, cephalexin, cloxacillin, vacomycin, minocycline or ciprofloxacin depending upon the severity, suspected causative organism and culture/sensitivity results. Gangrenous cellulitis is characterized by infection with necrosis of skin and underlying subcutaneous tissue due to various pathogens occurring at different site. Ampicillin, gentamicin, and either metronidazole or clindamycin intravenously in standard doses are recommended for the treatment.

Estudo clínico de celulite orbitária e pré-septal na infância / Clinical study of orbital and preseptal cellulitis in childhood

Objetivo: Estudar retrospectivamente aspectos clínicos e terapêuticos em crianças portadoras de celulite orbitária e pré-septal. Métodos: Foram analisados 52 prontuários de pacientes com idades variando de um mês a doze anos, internados no período compreendido entre 1990 e 1998, com quadro de celulite orbitária ou pré-septal. Resultados: Trauma foi o fator predisponente mais freqüente das celulites orbitárias e pré-septais na infância, seguido pela sinusite e causas näo-definidas. As infecçöes, na grande maioria, tiveram localizaçäo pré-septal (94,2 por cento). As hemoculturas, realizadas em 21 pacientes, resultaram em 71 por cento de negatividade, seguido por positividade para S. aureus (19 por cento), H. influenzae (4,7 por cento) e flora mista (4,7 por cento). Todos os pacientes foram tratados e curados com antibioticoterapia utilizando 16 quimioterápicos em 25 diferentes esquemas terapêuticos. A drenagem cirúrgica foi realizada em apenas 7 pacientes. Conclusäo: A despeito da falta de uniformidade e diversidade de esquemas terapêuticos empregados nos casos estudados e da falta de avaliaçäo oftalmológica na maioria dos casos, os pacientes foram curados sem complicaçöes. Tal fato indica a necessidade de estudos prospectivos que visem a elaboraçäo de protocolo terapêutico para as celulites da regiäo orbitária na infância, que leve em consideraçäo a relaçäo custo-benefício positiva.

Proteína "C" reactiva en la evaluación de infecciones bacterianas en pediatría / The value of CRP in pediatrics bacterial infections

El estudio pretende determinar si la proteína "C" reactiva (PCR) cuantitativa es útil en el diagnóstico, evolución y pronóstico de las infecciones graves en pediatría. El ensayo se llevó a cabo e el Hosital del Niño "Dr. Ovidio Aliaga Uria" de la ciudad de La paz -Bolivia entre los meses de agosto y diciembre de 1998. Se estudiaron 89 pacientes de los cuales 39 fueron excluidos por diferentes causas; de los 50 restantes, cuyas edades fluctuaron entre 2 meses y 14 años, el 68 porciento correspondia al sexo femenino. el 42 porciento eran provenientes de medio urbano. Se admitieron 13 pacientes con meningitis purulenta, 10 con celulitis, 20 con neumonia y 7 con pielonefritis. Se les extrajo tres muestras de sangre en diferentes estadios de la enfermedad y se cuantificó PCR. (Valor normal 0.6 a 1.2 mg/dL); en todos los casos la cifra fue >4.8 mg/dL en la primera muestra y sólo 10 pociento de los pacientes con celulitis y neumonia presentaron discreta elevación al concluir el tratamiento, mientras que en los niños con meningitis y pielonefritis los valores se normalizaron. Un paciente con neumonia (PCR inicial 4.8 mg/dL) tratado con penicilina G cristalina presentó deterioro clínico y radiológico, coincidiendo con el ascenso de PCR a 9.6 mg/dL; al cambiarse el squema antimicrobiano (cloxacilina... cloranfenicol) mejoró el aspecto clinico y radiológico, momento en que la cifra de PCR retornó a niveles normales. Por los hallazgos se puede concluir que la PCR cuantitativa es útil en la evaluación de los padecimientos infecciosos en pediatria; orienta en lo que refiere ala remisión del cuaadro y la pertinencia de emplear, sustituir o discontinuar el tratamiento antimicrobiano.
