Cultivo versus metagenómica para la identificación bacteriana en pacientes con osteomielitis de pie diabético: una revisión sistemática / Culture and metagenomics as bacterial identification methods in patients with diabetic foot ulcers: a systematic review

BACKGROUND: Diabetic foot osteomyelitis (DFO) is a serious complication of infected ulcers in a diabetic patient. The identification of the infecting microorganisms is generally by culture, which causes a bias. Recently, metagenomics has been used for microbial identification. AIM: To systematically review the scientific literature related to DFO in the last 10 years to evaluate if culture and metagenomics are complementary. MATERIAL AND METHODS: To carry out the systematic review, PRISMA and Rayyan were used for the selection of studies, using three databases, using the keywords diabetes, osteomyelitis, culture and microbiome. Articles in English or Spanish were included, containing information related to bacterial identification in DFO. Characteristics of the technique, patients and frequency of bacterial appearance were collected. RESULTS: Twenty six articles were included, 19 used culture and 7 metagenomics. The patients were predominantly men (68%), with an average age of 61 years, 83% had type 2 diabetes and comorbidities, mainly vascular and neuropathy. The Families with the highest frequency of appearance using the culture technique were Enterobacteriaceae (29.3%) and Staphylococcaceae(28.3%) and with metagenomics Peptoniphilaceae (22.1%) and Staphylococcaceae (9.4%). Peptoniphilaceae were not identified in culture, although they were frequently identified by metagenomics. Methicillin- resistant Staphylococcus aureus, regularly identified by culture, was not identified using metagenomics. CONCLUSIONS: Comparing results, there is a certain complementarity between microbiological culture and sequencing to identify bacteria present in DFO.

Tratamento cirúrgico da osteomielite dos maxilares: relato de caso / Surgical treatment of osteomyelitis of the jaws: Case report / Tratamento quirúrgico de la osteomielitis de los maxilares: reporte de um caso

A Osteomielite dos Maxilares (OM) é uma inflamação óssea, de origem na maioria infecciosa, podendo atingir a porção medular e cortical dos ossos maxilares. Apresenta-se em maior extensão na mandíbula, devido ao pobre suprimento sanguíneo que essa possui, sendo mais prevalente em homens entre a faixa etária de 40 a 60 anos. Sua etiologia está relacionada principalmente às infecções odontogênicas, infecções secundárias e corpos estranhos ocasionais, como os implantes dentários. Tem-se por objetivo apresentar um relato de caso clínico sobre OM na região posterior da mandíbula, bem como sua associação a uma insatisfatória implantação dentária onde houve desenvolvimento de lesão peri-implantar. Paciente do gênero feminino, 53 anos, melanoderma, apresentou dor crônica, abaulamento ósseo sem outros sinais significativos na região de molares inferiores no lado direito, radiograficamente visualizava-se imagem mista sendo sugestiva de sequestro ósseo. Na história pregressa relatou ter realizado explantação na referida região após ser diagnosticada com peri implantite. Ao final do estudo concluiu-se que a afecção teve como causa a infecção bacteriana proveniente de contaminação durante a inserção de implante dentário. Optou-se por remoção cirúrgica do osso necrótico e inflamado... (AU)

Osteomyelitis of the Jaws (OM) is a bone inflammation, of mostly infectious origin, which can affect the medullary and cortical portion of the maxillary bones. It presents itself to a greater extent in the mandible, due to the poor blood supply that it has, being more prevalent in men between the age group of 40 to 60 years. Its etiology is mainly related to odontogenic infections, secondary infections and occasional foreign bodies, such as dental implants. The objective is to present a clinical case report on OM in the posterior region of the mandible, as well as its association with an unsatisfactory dental implantation, where there was development of a peri-implant lesion. Female patient, 53 years old, melanoderma, presented chronic pain, bone bulging without other significant signs in the region of lower molars on the right side, radiographically a mixed image was visualized, suggesting bone sequestration. In her previous history, she reported having performed explantation in that region after being diagnosed with peri-implantitis. At the end of the study, it was concluded that the disease was caused by bacterial infection from contamination during dental implant insertion. We opted for surgical removal of the necrotic and inflamed bone... (AU)

La osteomielitis de los maxilares (OM) es una inflamación de los huesos, en su mayoría de origen infeccioso, que puede afectar la porción medular y cortical de los huesos maxilares. Se presenta en mayor medida en la mandíbula, debido a la escasa irrigación sanguínea que tiene, siendo más prevalente en hombres entre el grupo de edad de 40 a 60 años. Su etiología se relaciona principalmente con infecciones odontogénicas, infecciones secundarias y cuerpos extraños ocasionales, como los implantes dentales.

Infecciones osteoarticulares en niños / Osteoarticular infections in children

Las infecciones osteorticulares (IOA) en el niño son una causa importante de morbilidad y secuelas. Su pesquisa oportuna y el tratamiento eficiente pueden lograr excelentes resultados. La mejoría en las condiciones de salud de la población, y el cambio de los agentes etiológicos han variado la forma de presentación y tratamiento. La existencia de gérmenes como Kingella kingae y Staphilococcus aureus multiresistente, contribuyen a la variabilidad de presentación de las infecciones osteoarticulares.El manejo de estas patologías requiere de un conocimiento del cuadro clínico, de los métodos de diagnóstico y las herramientas terapéuticas. Para obtener buenos resultados es requisito básico el enfrentamiento de estos pacientes en un equipo multidisciplinario de especialistas.En este manuscrito revisaremos los aspectos fundamentales de las infecciones osteoarticulares, según el enfoque que aplicamos en nuestros pacientes.

Osteoarticular infections are a substantial cause of morbidity and sequelae in children. Early diagnosis and efficient treatment can achieve excellent results. The improvement in the health conditions of the population and the change in the etiological agents have produced changes in their presentation and their required treatment. The existence of germs like Kingella kingae and Staphilococcus aureus multiresistant contribute to the variability of presentation of osteoarticular infections.The appropriate management of these pathologies requires knowledge of the clinical picture, diagnostic methods, and therapeutic tools. To obtain good results, it is a basic requirement that these patients be confronted by a multidisciplinary team of specialists.In this manuscript we will review the most fundamental aspects of osteoarticular infections according to the approach we apply to our patients

Cranial osteomyelitis as a complication of furuncular myiasis / Osteomielite craniana como complicação de miíase furuncular

ABSTRACT Objective: To report the case of an infant with infrequent cranial osteomyelitis as a complication of furuncular myiasis. Case description: The patient was a 4-month-old male who presented to the emergency department with a nodular skull lesion with edema, tenderness, pain, and purulent drainage, as well as progress of the ulcerated lesion and evidence of larvae inside. Antibiotic treatment was initiated, and the patient was taken to the operating room to remove the larvae, but he had no symptomatic improvement. A skull radiograph was taken to visualize the osteolytic lesion, and a 3D computed tomography scan showed osteomyelitis of the external parietal surface. Antibiotic management readjustment continued for a total of six weeks, and a skin flap was used with clinical improvement. Comments: Myiasis is defined as the infestation of vertebrates with fly larvae. In mammals, larvae can feed on host tissue and cause a wide range of infestations depending on their location in the body. The cranial osteomyelitis as a complication of myiasis described in this report seems to be an exceptional case.

RESUMO Objetivo: Relatar um caso de criança com osteomielite craniana infrequente como complicação da miíase furuncular. Descrição do caso: Paciente do sexo masculino, com quatro meses de idade, que se apresentou no pronto-socorro com lesão nodular no crânio com edema, sensibilidade, dor e drenagem purulenta, com evolução da lesão ulcerada e evidência de larva no interior. O tratamento com antibióticos foi iniciado e o paciente foi levado à sala de cirurgia para remover as larvas, mas não houve melhora. Uma radiografia do crânio foi realizada para visualizar a lesão osteolítica e uma tomografia computadorizada em 3D mostrou osteomielite da superfície parietal externa. O reajuste do tratamento com antibióticos foi mantido por um total de seis semanas e um retalho cutâneo foi realizado com melhora clínica. Comentários: Miíase é definida como a infestação de vertebrados com larvas de moscas. Nos mamíferos, as larvas podem se alimentar do tecido hospedeiro e causar uma ampla variedade de infestações, dependendo da sua localização no corpo. A osteomielite como complicação da miíase, apresentada nesse caso, parece ser uma forma não usual de complicação dessa doença.

Occurrence of unusual haemoglobinopathies in balochistan: hb sd and hb se - presentation with osteomyelitis / Ocorrência de hemoglobinopatias incomuns no baluchistão: hb sd e hb se - apresentação com osteomielite

ABSTRACT Objective: To describe two cases of unusual variants of sickle cell disease. Case description: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemoglobin electrophoresis, whereas the other was diagnosed with sickle cell SE disease. Both were diagnosed based on the presentation of osteomyelitis. Comments: Haemoglobin SD disease (Hb SD) and haemoglobin SE disease (Hb SE) are rare haemoglobinopathies in the world. The lack of available literature suggests that both are variants of sickle cell disease (SCD), with heterogeneous nature. The prevalence of sickle cell disease with compound heterozygotes was found at a variable frequency in the population of the Asian Southeast. The frequency of osteomyelitis in SCD is 12 to 18%, but its occurrence among variant haemoglobinopathies is little reported. Both reported cases presented with osteomyelitis as a characteristic of the disease presentation.

RESUMO Objetivo: Descrever dois casos de variantes raras da hemoglobinopatia falciforme. Descrição do caso: Apresentamos aqui dois casos de hemoglobinopatias variantes das células falciformes, de famílias não relacionadas, no estado do Baluchistão (Paquistão), sendo um diagnosticado como doença da hemoglobina SD na eletroforese de hemoglobina, enquanto o outro com doença da hemoglobina SE. Ambos foram diagnosticados a partir da apresentação de osteomielite. Comentários: Hemoglobina SD (Hb SD) e hemoglobina SE (Hb SE) são hemoglobinopatias raras no mundo. A escassez de literatura disponível sugere que ambas são variantes da doença falciforme (DF) com natureza heterogênea. A prevalência de hemoglobinopatia falciforme com heterozigosidade composta foi encontrada com frequência variável na população do sudeste asiático. A frequência de osteomielite na DF é de 12 a 18%, mas sua ocorrência entre as hemoglobinopatias falciformes variantes é pouco relatada. Os dois casos reportados apresentaram osteomielite como característica de apresentação da doença.

A rare cause of vertebral osteomyelitis: the first case report of rat-bite fever in Portugal

Abstract Rat-bite fever is a rarely diagnosed illness caused by Streptobacillus moniliformis . Although this disease is distributed worldwide, there have been few cases reported in Europe. Here, we report a case of vertebral osteomyelitis and sternoclavicular septic arthritis caused by S. moniliformis in a Portuguese patient previously bitten by a rat. Laboratory diagnosis was performed using molecular identification. This is the first case report of rat-bite fever in Portugal. The case described here serves as a reminder for physicians to consider this diagnosis in patients who have developed fever syndromes after being in contact with rodents.

Osteomielitis fúngica en niños quemados / Fungal osteomyelitis in burned children

Introducción: En pacientes pediátricos quemados la osteomielitis fúngica es una complicación infrecuente que conduce a una significativa morbilidad. La información en la literatura está limitada a unos escasos reportes de casos. Objetivo: Describir las características clínicas, epidemiológicas y de evolución de niños quemados con osteomielitis fúngica. Métodos: Se llevo a cabo un estudio retrospectivo y descriptivo de pacientes mayores de 1 mes y menores de 18 años quemados con osteomielitis fúngica internados en el hospital Juan P. Garrahan, un hospital terciario en Buenos Aires, Argentina. Resultados: entre enero del 2007 y enero del 2017, de 600 niños quemados, 9 pacientes presentaron diagnóstico confirmado de osteomielitis fúngica. La mediana de edad fue de 42.5 meses (RIC, 27-118 meses) y la mediana de superficie quemada fue de 33.5% (RIC, 18.5-58%). La osteomielitis fue diagnosticada con una mediana de 30 días luego de la quemadura. Las localizaciones más frecuentes de osteomielitis fueron los miembros superiores y a nivel de calota. Los microorganismos aislados a partir del cultivo de hueso fueron: Fusarium spp. en tres pacientes, Mucor spp. en un paciente; Trichosporon asahii en un paciente; Cándida albicans en dos pacientes y Candida parapsilosis en dos pacientes. En dos casos la infección fúngica fue asociada con aislamientos bacteriano concomitante. Todos los pacientes presentaron hallazgos histopatológicos compatibles con osteomielitis. La mediana de tiempo de tratamiento fue de 44.5 días (RIC, 34.5- 65.5 días). Seis pacientes (67%) presentaron secuela motora. Conclusión: La osteomielitis fúngica fue infrecuente Candida spp. y Fusarium spp. fueron los hongos más comúnmente identificados. La secuela funcional fue frecuente (AU)

Introduction: In pediatric burn patients fungal osteomyelitis is a rare complication that leads to significant morbidity. Data in the literature are limited to sporadic case reports. Objective: To describe the clinical and epidemiological features and outcome in burned children with fungal osteomyelitis. Methods: A retrospective descriptive study was conducted in burn patients older than 1 month and younger than 18 years admitted to Hospital Juan P. Garrahan, a tertiary hospital in Buenos Aires, Argentina. Results: Between January 2007 and January 2017, of 600 burned children, nine had a confirmed diagnosis of fungal osteomyelitis. Median age was 42.5 months (IQR, 27-118 months) and median burn surface was 33.5% (IQR, 18.5-58%). Osteomyelitis was diagnosed at a median of 30 days after the burn. The most common location of osteomyelitis were the upper limbs and skull. The microorganisms isolated form bone cultures were Fusarium spp. in three patients, Mucor spp. in one patient; Trichosporon asahii in one patient; Candida albicans in two patients; and Candida parapsilosis in two patients. In two cases the funal infection was associated with concomitant bacterial isolation. In all patients, the histopathological findings were compatible with osteomyelitis. Median duration of treatment was 44.5 days (IQR, 34.5-65.5 days). Six patients (67%) had motor sequelae. Conclusion: Fungal osteomyelitis is a rare disease. Candida spp. and Fusarium spp. were most frequently identified fungi. Functional sequelae were common (AU)

Análise do perfil de atendimentos por osteomielite em pacientes acima de 60 anos em regiões brasileiras / Analysis of the profile of osteomyelitis care in patients over 60 years of age in Brazilian regions

Objetivo: Realizar uma análise estatística das internações de pacientes idosos com osteomielite, por região brasileira. Métodos: Foram pesquisadas informações de saúde disponíveis na plataforma do Departamento de Informática do Sistema Único de Saúde (DATASUS), avaliando-se, de 2012 a 2016, as variáveis: internações por osteomielite (M86 do CID-10), faixa etária acima de 60 anos, sexo e etnia. Resultados: De 78.967 pacientes internados por osteomielite no Brasil, 16.736 (21,19%) eram idosos, com a Região Sudeste registrando maior número de casos (7.163 internações; 42,79%), seguida da Nordeste (5.165; 30,86%), da Sul (2.462; 14,71%), da Centro-Oeste (1.162; 6,9%) e da Norte (784; 4,6%). O número de internações manteve-se relativamente constante, com média de 3.347 casos por ano. Pacientes de 60 a 69 anos foram os com maior registro (8.786 casos; 52,49%). Em segundo lugar, ficaram os de 70 a 79 anos (5.232; 31,2%) e, por último, os acima de 80 anos (2.718; 16,24%). Em relação ao sexo, o masculino notificou 9.232 internações (55,16%), com 7.504 (44,83%) para o feminino. A etnia branca apresentou maior número de notificações (6.117; 36,54%), principalmente nas Regiões Sudeste e Sul, seguida pela parda (4.947; 29,55%), que se destacou dentre as demais regiões. Conclusão: Diante da heterogeneidade de fatores que predispõem à osteomielite, com destaque para o diabetes mellitus, urge garantir um manejo precoce da infecção e de comorbidades causadoras, a fim de evitar complicações debilitantes ao idoso, bem como prevenir futuras recidivas e internações onerosas ao sistema de saúde brasileiro. (AU)

Objective: To perform a statistical analysis of hospitalizations of elderly patients with osteomyelitis, by Brazilian region. Methods: Health information available from the Informatics Department of the Unified Health System (DATASUS) platform was investigated, from 2012 to 2016. The following variables were assessed: admissions due to osteomyelitis (ICD-10 M86), age group over 60, gender and ethnicity. Results: Of the 78,967 patients hospitalized due to osteomyelitis in Brazil, 16,736 (21.19%) were elderly, with the Southeast Region having a higher number of cases (7,163 admissions - 42.79%), followed by the Northeast (5,165 - 30.86%), South (2,462 - 14,71%), Midwest (1,162 - 6,9%), and North (784 - 4,6%). The number of hospitalizations remained relatively constant, with an average of 3,347 cases per year. Patients aged 60 to 69 years were the ones with the highest registry (8,786 cases - 52.49%); in second place, those aged 70 to 79 years (5,232 - 31.2%) and, finally, those above 80 years old (2,718 - 16.24%). Regarding gender, males accounted for 9,232 hospitalizations (55.16%), with 7,504 (44.83%) for females. White people had the highest number of reports (6,177 - 36.54%), mainly in the Southeast and South Regions, followed by browns (4,947 - 29.55%), who were more prevalent in the other regions. Conclusion: In view of the heterogeneity of factors that predispose to osteomyelitis, especially diabetes mellitus, it is urgent that early management of the infection and causative comorbidities is ensured, in order to avoid debilitating complications for the elderly, as well as to prevent future relapses, and costly hospitalizations to the Brazilian health system.

Formación de un solo hueso en el antebrazo / Formation of a single bone in the forearm

En 1921 se describió la formación de un solo hueso del antebrazo como un proceder de rescate para una pseudoartrosis en el radio distal. Se presentan dos casos con un defecto óseo significativo en el antebrazo, secundario a procesos sépticos, a los que se les realizó la técnica de "un solo hueso". A un paciente se le transfirió la diáfisis del cúbito proximal a la metáfisis distal del radio con fijación de la articulación radiocubital distal para garantizarle estabilidad a la muñeca. Al segundo caso se le fijó la metáfisis proximal del cubito con la diáfisis distal del radio. Ambos presentaron una evolución posoperatoria favorable, con recuperación funcional y estética de la extremidad(AU)

In 1921, the formation of a single forearm bone was described as a rescue procedure for a pseudoarthrosis in the distal radius. We present two cases with significant bone defect in the forearm, secondary to septic processes, to which the "single bone" technique was performed. A patient was transferred the diaphysis of the proximal ulna to the distal metaphysis of the radius with fixation of the distal radioulnar joint to ensure stability to the wrist. In the second case, the proximal metaphysis of the ulna was fixed with the distal diaphysis of the radius. Both patients had favorable postsurgical evolution, with functional and aesthetic recovery of their limb(AU)

Osteomielitis por Mycobacterium tuberculosis / Mycobacterium tuberculosis osteomyelitis

Resumen Introducción: en Uruguay se ha notificado un aumento en el número de casos de tuberculosis en niños con formas pulmonares y extrapulmonares. La infección osteoarticular representa 10%-15% de las formas extrapulmonares. Objetivo: alertar sobre una etiología poco habitual de osteomielitis cuya forma de presentación genera dificultades diagnósticas. Caso clínico: niña de 18 meses, previamente sana. Consulta por edema e impotencia funcional de tobillo derecho de tres meses de evolución, en apirexia. La radiografía muestra múltiples imágenes geódicas en el sector distal de la diáfisis con secuestro en peroné derecho. Se realiza punción ósea obteniéndose líquido serohemático. El cultivo de dicha muestra y el hemocultivo fueron negativos. Luego de recibir clindamicina 21 días más gentamicina 10 días por via intravenosa y dos limpiezas quirúrgicas, se otorga alta con cefuroxime acetil vía oral. El cultivo de la muestra ósea desarrolló Mycobacterium tuberculosis. Se inició tratamiento con isoniacida, rifampicina y piracinamida. No fue identificado el caso índice. Discusión: la presentación clínica de la tuberculosis ósea es generalmente insidiosa lo que generando dificultades y retraso en el diagnóstico. Sólo la biopsia permite confirmar el diagnóstico. La situación epidemiológica actual obliga a descartar posible etiología tuberculosa ante un proceso inflamatorio osteoarticular de evolución tórpida. El tratamiento oportuno y adecuado requiere alto índice de sospecha y realización sistemática de punción ósea y/o articular.

Summary Introduction: in Uruguay, an increase in the number of cases of TB with pulmonary and extra-pulmonary involvement in children has been reported. Osteoarticular infections represent 10%-15% of extra-pulmonary involvement. Objective: to warn about an uncommon etiology of osteomyelitis whose presentation results in diagnostic difficulties. Clinical case: 18 month-old girl, previously healthy. Consultation was due to edema and right ankle functional insuficiency with three-month evolution, under apyrexia. X-ray imaging revealed multiple geodesic images in the distal portion of diaphysis, as well as a small sequestrum in right fibula. Through a bone puncture, serohematic fluid was extracted. Culture and hemoculture were negative. Treatment consisted of 21 days of intravenous clindamycin and 10 days of gentamicin. Two surgical debridements were performed. Progressive recovery followed. The child was discharged under cefuroxime axetil oral suspension and later a bone culture showed positive results for Mycobacterium TB. Treatment with isoniazid, rifampin and pyrazinamide was started. Index case could not be identified. Discussion: clinical presentation of bone tuberculosis is generally insidious. This explains difficulties and delays in diagnosis. It is remarkable that only biopsy allows the confirmation of diagnosis. The present epimediologic condition forces us to rule out possible TB etiology in the presence of an inflammatory osteoarticular process of lethargic evolution. Timely and accurate treatment requires a high degree of suspicion, as well as the performance of systematic bone and/or joint puncture.

Revisión de los casos de osteomielitis diagnosticados en el Hospital México durante los años 2013-2014 / Review of cases of osteomyelitis diagnosed at the Hospital Mexico during the years 2013-2014

ResumenLa osteomielitis es una infección progresiva del hueso, resultado de un proceso inflamatorio destructivo, seguido de la formación de hueso nuevo. Esta es resultado de la inoculación, ya sea de forma directa, por contigüidad, o por diseminación sanguínea (vía hematógena) de un microorganismo que puede evolucionar en días o semanas y puede progresar a una infección crónica con osteonecrosis, pérdida ósea y/o fístula.El presente estudio evidenciará los reportes bacteriológicos y prueba de sensibilidad antibiótica, de los patógenos más comunes de las muestras identificadas como hueso o médula ósea procesadas en el laboratorio de Bacteriología del Hospital México, obtenidas de pacientes con el diagnóstico de osteomielitis durante los años 2013 y 2014.Mediante este estudio se pretende instaurar un precedente epidemiológico y etiológico con datos costarricenses que sirva de base para futuras investigaciones y/o protocolos de tratamiento.

AbstractOsteomyelitis is a progressive bone infection resulting from a destructive inflammatory process followed by new bone formation. It's the result of direct or indirect inoculation of a microorganism, infection by adjacent tissues or hematogenous dissemination. This process can evolve in days or weeks and can progress to a chronic infection with osteonecrosis, bone loss and/or fistula formation.This study will show the bacteriological reports and antibiotic sensitivity test of the most common pathogens in samples identified as bone or bone marrow processed in the Bacteriology Laboratory of Hospital Mexico obtained from patients with diagnosis of osteomyelitis during 2013 and 2014.The objective with this study is to establish an epidemiological and etiological precedent with costarrican data that can be used as background for future investigations and/or treatment protocols.

Osteomielitis del calcáneo secundaria a la prueba de Guthrie: A propósito de un caso / Calcaneus osteomyelitis secondary to Guthrie test: Case report

La osteomielitis del calcáneo es una infección rara en los recién nacidos. Entre los factores etiológicos se encuentran los procedimientos invasivos, la prematurez y el bajo peso al nacer. Los signos clínicos pueden ser leves. Presentamos el caso de una recién nacida con osteomielitis del calcáneo secundaria a la obtención de una muestra mediante la prueba de Guthrie. La paciente fue hospitalizada debido a hinchazón, enrojecimiento y aumento de la temperatura del talón. En la ecografía de los tejidos superficiales se observó edema de contenido espeso en la región posterior del pie derecho. Se realizó la punción y el drenaje del contenido y al cultivarlo se aisló Staphylococcus aureus sensible a la meticilina. En la resonancia magnética de la extremidad se observó una lesión del tejido en el pie derecho, edema, inflamación y realce del contraste. Se le administró un tratamiento con sulbactam y ampicilina por vía intravenosa y ácido clavulánico por vía oral durante seis semanas. Durante el seguimiento, la paciente se recuperó de los síntomas clínicos sin necesidad de realizar una limpieza quirúrgica. A modo de conclusión, en el diagnóstico diferencial de la hinchazón del talón en los neonatos sometidos a procedimientos invasivos, como la prueba de Guthrie, debe tenerse en cuenta la osteomielitis del calcáneo.

Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture. Extremity magnetic resonance imaging showed tissue defect in right foot, edema-inflammation and contrast enhancement. Intravenous sulbactam-ampicillin and oral amoxicillin and clavulanic acid were given for 6 weeks. In follow-up, clinical symptoms recovered without curettage. In conclusion; calcaneous osteomyelitis should be considered in the differential diagnosis of swelling on heel in neonates who have been applied to invasive procedures as Guthrie test sample.

Osteomielitis en el cóndilo mandibular y su relación con la anemia / Osteomyelitis in the condyle of the jaw and its relationship with anemia

La osteomielitis se define como una inflamación progresiva del hueso, que se produce con mayor frecuencia en los huesos largos del cuerpo. Su etiología se relaciona con factores locales y/o sistémicos los que incluyen la anemia. La osteomielitis resultante de la anemia de células falciformes genera que la sangre sea más viscosa produciendo un bajo flujo sanguíneo conduciendo a infarto isquémico y necrosis del hueso, rara vez causado en los huesos faciales. Paciente ingresado a urgencia por un aumento de volumen en la región preauricular izquierda de un mes de evolución, blando, fluctuante, límites mal definidos, de 5x4 cm de diámetro, afebril, sin cambios de coloración. Presentaba trismus y dolor a la palpación. Hace cinco meses había sido tratado por una osteomielitis frontoparietal izquierda con absceso subgaleal. Antecedentes mórbidos del paciente: alcohólico crónico y anemia en tratamiento. El paciente fue hospitalizado con tratamiento de Clocaxiclina endovenoso, coleccionándose en la región preauricular. Se realizó la biopsia dando como resultado osteomielitis de cóndilo mandibular. La osteomielitis presentada en el cóndilo mandibular pudo ser recidiva de la osteomielitis anterior o haber sido causada por la anemia. Sin embargo, la osteomielitis frontoparietal se presentó sin causa aparente, pudiendo relacionarla con la anemia que cursaba.

Osteomyelitis is defined as a progressive inflammation of the bone, which occurs most frequently in the long bones of the body. Its etiology is related to local and / or systemic factors that include anemia. Osteomyelitis resulting from sickle cell anemia results in the blood being more viscous producing a low blood flow leading to ischemic attack and bone necrosis. Patient presented with increased volume in the left preauricular region following one month of evolution, soft, fluctuating, ill-defined limits, 5x4 cm in diameter, afebrile, without discoloration. He had trismus, tenderness and had been admitted to the emergency room five months earlier, for osteomyelitis with subgaleal abscess. Patient`s background included anemia and treatment for chronic alcoholism. The patient was hospitalized with intravenous treatment of cloxacilline, resulting in increased preauricular volume with defined limits. Results following a biopsy showed condyle osteomyelitis. Osteomyelitis presented in the condyle may be the recurrence of osteomyelitis or may have been caused by the anemia. However, frontoparietal osteomyelitis has no apparent cause and could be associated with anemia.

Osteomielitis por Yokenella regensburgei después de una craneotomía en una paciente inmunocompetente / Osteomyelitis due to Yokenella regensburgei following craniotomy in an immunocompetent patient

Yokenella regensburgei es un bacilo Gram negativo de la familia Enterobacteriaceae, que puede encontrarse en agua de pozos, alimentos y en el tubo digestivo de insectos y reptiles. Aunque se ha aislado de muestras provenientes de seres humanos, pocas veces se ha reportado como causante de infección y, en tales casos, especialmente en pacientes inmunosuprimidos. Se presenta aquí el primer caso de osteomielitis secundaria a una infección por Y. regensburgei en una paciente inmunocompetente después de un procedimiento quirúrgico.

The gram-negative bacillus Yokenella regensburgei (of the Enterobacteriaceae family) can be found in groundwater and foodstuffs, as well as the digestive tracts of insects and reptiles. Although it has been isolated from humans since its original description, it has rarely been reported as a cause of infection, and then, only in immunosuppressed patients. We report the first case of post-surgical secondary osteomyelitis due to Y. regensburgei in an immunocompetent woman who had undergone a craniotomy.

Osteomielitis maxilar y mandibular en pacientes pediátricos / Pediatric maxillary and mandibular osteomyelitis

Introducción: La osteomielitis es un cuadro, de presentación ocasional, que resulta como complicación de diversas etiologías y requiere un tratamiento quirúrgico y médico inmediato. Objetivos: Evaluar los resultados de patología informados como osteomielitis a nivel de los maxilares en pacientes pediátricos, tanto de la mandíbula como del maxilar superior, los cuales requirieron tratamiento quirúrgico y cobertura antibiótica en el periodo del 2008 – 2013. Material y método: Estudio descriptivo y retrospectivo, realizado en el Instituto Nacional de Salud del Niño. Resultados: Se encontró predominio en el sexo masculino (64.7%) y mayor presentación en menores de 10 años de edad (91%), la mandíbula fue en mayor frecuencia afectada (92,1%); con predominio de osteomielitis crónica en 82,4% de los casos. La región del cuerpo y ángulo mandibular resultaron los más afectados con 75 y 62,5% respectivamente. A todos los pacientes se les realizó limpieza quirúrgica y remoción de secuestros óseos con exodoncias de las piezas comprometidas. Conclusión: La cirugía junto a la cobertura antibiótica son la base del tratamiento el cual se busca erradicar el foco infeccioso y al microorganismo patógeno. Proponemos como cobertura antibiótica clindamicina y penicilina resistente a betalactamasa durante 8 semanas, en forma parenteral por 2 semanas como mínimo y luego vía oral hasta completar el tratamiento.

Introduction: Osteomyelitis is a picture of casual presentation, resulting as a complication of various etiologies and requires immediate surgical and medical treatment. Objective: To evaluate the results of pathology-level reported as osteomyelitis of the jaws in pediatric patients , both the jaw and the upper jaw, which required surgical treatment and antibiotic coverage, for the period from 2008 to 2013. Material Methods: Study descriptive, retrospective , held at the National Institute of Child Health Results : predominance was found in males ( 64.7 %) and higher filing under 10 years of age (91%), the mandible was more frequently affected (92.1 %) with a predominance of chronic osteomyelitis in 82.4 % of cases . The region of the mandibular body and angle were the most affected with 75 and 62.5 % respectively. All patients were performed surgical cleaning and removal of sequestra with extractions of compromised parts. Conclusion: Surgery with antibiotic coverage are the mainstay of therapy , which seeks to eradicate the source of infection and the pathogen. We propose as clindamycin antibiotic coverage lactamase resistant penicillin for 8 weeks parenterally for at least 2 weeks and then orally until complete.

A case of peripheral gangrene and osteomyelitis secondary to terlipressin therapy in advanced liver disease

Variceal bleeding and hepatorenal syndrome (HRS) are serious and life-threatening complications of advanced liver disease. Terlipressin is widely used to manage both acute variceal bleeding and HRS due to its potency and long duration of action. The most severe (though rare) adverse event is ischemia. The present report describes the case of a patient with gangrene and osteomyelitis secondary to terlipressin therapy. A 71-year-old male with alcoholic liver cirrhosis (Child-Pugh B) and chronic hepatitis C was admitted due to a drowsy mental status. The patient had several experiences of orthopedic surgery. His creatinine level had gradually elevated to 4.02 mg/dL, and his urine output decreased to 500 mL/24 hr. The patient was diagnosed as having grade III hepatic encephalopathy (HE) and type II HRS. Terlipressin and albumin were administered intravenously to treat the HRS over 11 days. Although he recovered from the HE and HRS, the patient developed peripheral gangrene and osteomyelitis in both feet. His right toes were cured with the aid of rescue therapy, but his left three toes had to be amputated. Peripheral gangrene and osteomyelitis secondary to terlipressin therapy occur only rarely, and there is no specific rescue therapy for these conditions. Thus, attention should be paid to the possibility of ischemia of the skin and bone during or after terlipressin therapy.

Osteomielitis crónica con periostitis proliferativa / Chronic osteomyelitis with proliferative periostitis

La osteomielitis crónica con periostitis proliferativa es un tipo de alteración caracterizada por una reacción periosteal exacerbada causada por un estimulo de baja intensidad, generalmente una lesión cariosa con patología periapical asociada. Actúa principalmente en niños y adolescentes con predilección por la región basilar de mandíbula. Clínicamente, se manifiesta a través de un aumento de volumen doloroso intra o extraoral, de consistencia endurecida. Radiográficamente presenta laminas óseas neoformadas, paralelas entre si con superficie cortical, observándose el aspecto típico de "cascara de cebolla". El tratamiento incluye el retiro del factor etiológico con o sin antibioterapia y posterior restablecimiento de la simetría facial del paciente. Este trabajo presenta un caso de osteomielitis crónica con periostitis proliferativa en una paciente de sexo femenino de 11 años de edad, causada por una lesión cariosa en el primer molar inferior izquierdo, quien fue sometida a exodoncia del diente comprometido con posterior restablecimiento de la simetría facial.

Chronic osteomyelitis with proliferative periostitis is a kind of osteomyelitis that is characterized by a great periosteal reaction resulting of low grade stimulation, usually a caries lesion associated a periapical pathology. It affects especially children and young adults, with the mandible as the most common site, usually in the inferior aspect. Clinically presents as a painless hard swelling intra and/or extra-oral. Radiographic aspects include bone layers new formed, parallel to each other and to the underlying cortical surface, giving the characteristic appearance of "onion skin". Treatment includes elimination of the cause, with or without antibiotics, being restored the facial symmetry of patient. The present article is a clinical case report of chronic osteomyelitis with proliferative periostitis affecting a female 11 year old patient, caused by a caries lesion in the left permanent first molar, that was submissed to a exodontia and the facial symmetry of the patient was restored with management.

Sternal osteomylitis due to arrow-head injury: A rare case report.

Sternal osteomyelitis secondary to penetrating trauma is an uncommon entity and only few cases have been reported. We report a case of sternal osteomyelitis in a patient with sickle-cell anaemia with a unique past history of arrow-head injury who presented with signs and symptoms of sternal infection. Imaging studies suggested osteomyelitis and the patient underwent sternal debridement, with a successful outcome.
