ABSTRACT

Resumen En la terapia con oxígeno hiperbárico (HBO) se utiliza oxígeno al 100% de concentración en una cámara presurizada con presiones supraatmosféricas, que corresponden de 2 a 3 atmósferas. Los mecanismos por los cuales funciona esta terapia se relacionan con propiedades físicas de los gases y su comportamiento fisiológico en el organismo, lo que lleva finalmente a la hiperoxia, evento fisiológico que permite la obtención de diversos efectos beneficiosos. La evidencia en medicina ha demostrado su utilidad mayormente en la enfermedad por descompresión, infecciones cutáneas graves e intoxicación por monóxido de carbono. En el ámbito de la otorrinolaringología ha probado ser útil en algunas enfermedades como la hipoacusia súbita idiopática, tanto como terapia única como asociada al uso de corticosteroides, como en la osteomielitis refractaria del oído externo, la que en conjunto con antibioticoterapia y manejo quirúrgico presenta un evidente aumento en la tasa de mejoría. Cabe mencionar que la terapia con HBO ha demostrado también beneficios en los tratamientos y complicaciones posteriores a la radiación en pacientes con cáncer de cabeza y cuello. Es importante mencionar que la terapia con HBO no está exenta de riesgos y requiere que los pacientes cumplan con características específicas para su utilización, por lo que su indicación debe ser juiciosa y en casos seleccionados.


Abstract In hyperbaric oxygen therapy, 100% pure oxygen is used in a pressurized chamber with super atmospheric pressures which correspond to 2-3 atmospheres. The mechanism by which this treatment works is related to the physical properties of gases and their physiological behavior in the body, which leads to hyperoxia, the physiological event which allows for diverse beneficial health effects. The evidence in medicine has proven its utility mainly in decompression sickness, severe skin infections and carbon monoxide poisoning. In the otolaryngology field it has been proven useful in diseases like idiopathic sudden sensorineural hearing loss, both as the only treatment and as a concurrent treatment along with corticosteroids, in malignant otitis externa which in conjunction with antibiotic treatment and a surgical approach presents a clear increase in improvement rates. It must be mentioned that hyperbaric chamber treatment has also shown benefits in radiation treatment and post radiation complications in head and neck cancer patients. It is important to note that hyperbaric oxygen therapy is not without risks and patients must meet specific criteria for it to be applied, therefore it must be indicated using careful judgement and only in necessary cases.

ABSTRACT

Objective: To investigate the clinical effects of en bloc resection and debridement combined with gluteus maximus muscle flap in the treatment of ischial tubercle pressure ulcer complicated with chronic osteomyelitis. Methods: A retrospective observational study was conducted. From May 2018 to February 2020, 8 patients with pressure ulcers on the ischial tuberosity combined with chronic osteomyelitis who met the inclusion criteria were admitted to Fuyang Minsheng Hospital, including 5 males and 3 females, aged 38-69 years, with unilateral lesions in 6 patients and bilateral lesions in 2 patients. According to the anatomical classification of Cierny-Mader osteomyelitis, there were 6 patients (7 sides) with focal type, and 2 patients (3 sides) with diffuse type. The wound areas were 3 cm×2 cm to 12 cm×9 cm on admission. The pressure ulcer and chronic osteomyelitis lesions were completely removed by en bloc resection and debridement. The chronic infectious lesions were transformed into sterile incisions like fresh wounds by one surgical procedure, and the gluteus maximus muscle flaps with areas of 10 cm×6 cm to 15 cm×9 cm were excised to transfer and fill the ineffective cavity. The wounds of 5 patients were sutured directly, and the wounds of 3 patients were closed by local flap transfer. The intraoperative blood loss volume and blood transfusion, and length of hospital stay of patients were recorded. The incision healing and flap survival of patients were observed after operation. The recurrence of pressure ulcer and osteomyelitis, the appearance of the affected area, and the secondary dysfunction and deformity of the muscle flap donor site of patients were observed during followed up. Results: The intraoperative blood loss volume of the 8 patients was 220 to 900 (430±150) mL; 5 patients received intraoperative blood transfusion, of which 2 patients received 3 U suspended red blood cells and 3 patients received 2 U suspended red blood cells. The length of hospital stay was 18 to 29 (23.5±2.0) d for the 8 patients. In this group of patients, the incisions of 7 patients healed, while in one case, the incision suture was torn off during turning over and healed after secondary suture. The flaps survived well in 3 patients who underwent local flap transfer. During the follow-up period of 6-20 months, no recurrence of pressure ulcer or osteomyelitis occurred in 8 patients, the affected part had skin with good texture, mild pigmentation, and no sinus tract formation, and no secondary dysfunction or deformity occurred in the donor site. Conclusions: The en bloc resection and debridement combined with gluteus maximus muscle flap has good clinical effects on ischial tubercle pressure ulcer complicated with chronic osteomyelitis. Neither pressure ulcer nor osteomyelitis recurs post operation. The skin texture and appearance of the affected area are good, and the donor site has no secondary dysfunction or deformity.

ABSTRACT

To explore the effectiveness and safety of a Chinese medicinal decoction Wuwei Xiaodu Drink (WWXDD) in inhibiting chronic osteomyelitis via regulatory T cells signaling. The effective constitutes of WWXDD and osteomyelitis related genes were screened. Target proteins were cross-validated using the Venny database. GO function and KEGG pathway analysis were performed for target proteins, while pharmacological network was constructed. The bone properties were analyzed by HE staining and the concentrations of immune factors were measured by ELISA. The expression of CTLA-4 and Foxp3 mRNA and STAT5, p-STAT5, CTLA-4 and Foxp3 protein were detected using Real-time PCR and Western blot, respectively. FACS was used to analyze the percentages of cells. A total of 117 genes overlapped between 785 target genes of the active compounds of WWXDD and 912 osteomyelitis related genes. Inflammation-related genes, including IL-6, TNFα, IL-1β and IL-2 showed high connection degree in the drug-compound-disease-target network. GO function and KEGG pathway analysis revealed that 117 intersection genes mainly enriched in virus infection related pathways, immune related pathways and chemokine signaling pathway. Furthermore, the development of chronic osteomyelitis was suppressed in model rats after treatment with WWXDD. Meanwhile, the concentrations of IL-2 and CD4+CD25+Foxp3 Treg percentages together with the levels of p-STAT5, CTLA-4 and Foxp3 were also down-regulated. Furthermore, IL-2 and WWXDD drug-containing serum exhibited opposite effects on regulating IL-2, IL-10, TGF-β1, Foxp3, CTLA4 and STAT5. In addition, a STAT5 phosphorylation inhibitor suppressed the expression of Foxp3 and CTLA-4. WWXDD can treat chronic osteomyelitis through suppressing the main regulating factors of Tregs and interfere its immunodepression. Our results bring a new solution for chronic osteomyelitis.

ABSTRACT

OBJECTIVE@#To observe clinical effect of calcium sulfate on promoting natural healing of docking sites during bone transport.@*METHODS@#A retrospective study was performed on the patients with posttraumatic chronic osteomyelitis treated by bone transport and calcium sulfate implantation from January 2013 to January 2018. There were 23 males and 4 females, aged from 20 to 61 years old with an average of (44.30±10.00) years, the courses of disease ranged from 3 to 86 months with an average of(13.26±16.47) months. Sixteen patients with posttraumatic chronic osteomyelitis were caused by internal fixation of closed fractures, and 11 patients were caused by open fractures. The length of bone defects after debridement ranged from 4 to 14 cm with an average of(9.11±2.57) cm. Postoperative complications, natural healing rate of the docking sites, external fixation index were observed, Checketts & Otterburn pin-tract infection classification was used to evaluate pin-tract infection, and Paley evaluation criteria was used to evaluate bone and function results.@*RESULTS@#Twenty-seven patients were followed up from 26 to 41 months with an average of (31.32±3.37) months. It did not happened skin embedded between bone stumps in all patients. All patients obtained bone union at (17.78±5.43) months after operation.Among them, 25 patients healed naturally in the docking sites, 2 patients with poor compliance healed after debridement and bone grafting in the docking sites. One patient occurred equines deformity, and no re-fracture or recurrence of infection occurred. According to Checketts & Otterburn pin tract infection classification, 22 patients (41 pin tracts)occurred pin-tract infection with varying degrees. The average external fixation index was (2.02±0.24) months/cm(ranged from 1.6 to 2.4 months/cm). According to Paley evaluation criteria, bony results showed 21 patients obtained excellent results, 5 good, and 1 moderate;functional results showed 19 patients got excellent results, 7 good, and 1 moderate.@*CONCLUSION@#During bone transport, the implantation of calcium sulfate on the bone defect areas could prevent skin embedding between the bone stumps, benefit for the natural healing of the docking sites, and could avoid the second-stage debridement and bone grafting for most patients. However, it should be noted that compliance needs to be increased.

ABSTRACT

Background: Cancrum oris is a rapid and devastating infectious disease of the orofacial region, which can be life threatening in its fulminant stage. Infection of bone (osteomyelitis) is a possible sequelae of Noma (cancrum oris) and is more likely due to late presentation especially in our environment. A literature search revealed scanty research describing osteomyelitis in Noma patients. Objective: To analyze the clinico­pathology of osteomyelitis in Noma patients diagnosed and treated at Noma Children Hospital, Sokoto.Methods: The design was a 2-year retrospective study of records of Thirty­two patients who had sequestrectomy secondary to osteomyelitis in Noma (Cancrum oris). Age, gender, jaws affected and side of involvement were analyzed Results: The age ranged from 2­11 years with mean ±standard deviation 5.47 ± 2.68 years was recorded. Osteomyelitis in Noma patients was found among 17 (53.10%) males compared to 15 (46.90%) females. In 20 (62. 50%) of the cases, anterior maxillary involvement was observed and the remaining 12 (37. 50%) was found at the mandibular posterior region and it is more common on the left side. Result of histopathology showed both acute and chronic inflammatory cells. Necrosis and bone hyperactivity was observed in most of the slides. Conclusion: Osteomyelitis is a common complication of Noma and its treatment is of paramount importance for adequate management of Noma patients.

ABSTRACT

Resumen: La complicación más frecuente de la úlcera del pie diabético (UPD) es la infección, siendo el desencadenante principal de amputaciones menores y mayores. La osteomielitis (OM) está presente hasta en el 60% de los casos y su tratamiento es un desafío, generando controversias según las formas clínicas de presentación. La resección del hueso infectado ha sido el tratamiento estándar, pudiendo generar secuelas funcionales y úlceras recurrentes. En las últimas dos décadas se propuso el tratamiento antimicrobiano con cirugía conservadora o sin cirugía en las lesiones del antepie, con resultados satisfactorios. Objetivo: presentar los resultados del tratamiento médico de la osteomielitis del pie en pacientes diabéticos, priorizando resecciones mínimas que eviten amputaciones desestabilizantes de su biomecánica. Se evaluaron seis pacientes con diabetes mellitus (DM) tratados en la Unidad de Pie, con osteomielitis de falanges, metatarsianos y calcáneo, tratados con antibióticos durante 7±2 semanas y con resecciones limitadas al antepié, con buena evolución. Durante un año de seguimiento hubo ausencia de cualquier signo de infección en el sitio inicial o contiguo de la lesión, preservando el apoyo. Conclusión: la cirugía con resección mínima sin amputación local o de alto nivel tiene éxito en casos seleccionados de osteomielitis del pie diabético. Deben realizarse ensayos prospectivos para determinar sus beneficios frente a otros enfoques.


Abstract: Infection is the most frequent complication in diabetic foot ulcers, and it is the main cause of minor and major lower extremities amputations. Osteomyelitis accounts for 60% of cases and it constitutes a challenge when it comes to treatment, since controversies arise depending on its clinical presentation. Resection of the infected bone has been the golden standard, despite it may cause functional sequelae and recurring ulcers. In the last two decades antibiotic therapy has emerged, combined with a conservative surgical approach or no surgery in forefoot lesions, the results being satisfactory. Objective: to present the results of medical treatment of foot osteomyelitis in diabetic patients, prioritizing minimal resections that avoid amputations which alter the biomechanics of the foot. The study evaluated 6 diabetic patients assisted at the Diabetic Foot Unit, with phalanx, metatarsal and calcaneal osteomyelitis. They received antibiotic therapy for 7 ± 2 weeks and resections were limited to the forefoot, showing good evolution. During a one-year follow-up, there were no signs of infection in the initial site or adjacent to the lesion, support of the foot being preserved. Conclusion: minimum resection surgery with no local or major amputation is a successful therapy in selected cases of diabetic foot osteomyelitis. Prospective trials are necessary to determine benefits of this management when compared to other approaches.

A osteomielite (OM) está presente em até 60% dos casos e seu tratamento é um desafio, gerando controvérsias dependendo de suas formas clínicas de apresentação. A ressecção do osso infectado tem sido o tratamento padrão, podendo gerar sequelas funcionais e úlceras recorrentes. Nas últimas duas décadas, o tratamento antimicrobiano com cirurgia conservadora ou sem cirurgia tem sido proposto nas lesões do antepé, com resultados satisfatórios. Objetivo: apresentar os resultados do tratamento clínico da osteomielite do pé em pacientes diabéticos, priorizando ressecções mínimas que evitem amputações desestabilizadoras de sua biomecânica. Foram avaliados seis pacientes diabéticos (DM) atendidos na Unidade do Pé, com osteomielite de falanges, metatarsos e calcâneo, tratados com antibióticos por 7±2 semanas e ressecções limitadas ao antepé com boa evolução. Durante um ano de seguimento, não houve sinais de infecção no local inicial ou contíguo da lesão, preservando o suporte. Conclusão: a cirurgia com ressecção mínima sem amputação local ou de alto nível é bem-sucedida em casos selecionados de osteomielite do pé diabético. Ensaios prospectivos devem ser realizados para determinar os benefícios desta em relação a outras abordagens.

ABSTRACT

RESUMEN Introducción: el principal patógeno en las infecciones osteoarticulares es el Staphylococcus aureus, los esquemas de tratamiento recomendados se basan en la literatura estadounidense o europea, no hay datos de estudios locales. El propósito de este estudio es conocer el perfil epidemiológico en las infecciones osteoarticulares del Hospital Infantil San Vicente Fundación (Medellín, Colombia) y las características de los pacientes afectados. Materiales y métodos: revisión retrospectiva de historias de pacientes entre los 0 y 15 años con diagnóstico de infección osteoarticular en el Hospital Infantil San Vicente Fundación, se detallaron las variables demográficas de la patología y los antecedentes relevantes para caracterizar el perfil epidemiológico de las infecciones osteoarticulares. Resultados: identificamos 72 pacientes con infección osteoarticular. La infección más común fue la artritis séptica (40 %), seguida por la osteomielitis aguda (37 %). La cadera (18 %) y la tibia (31 %) fueron la articulación y el hueso afectados con mayor frecuencia. La mayoría de las infecciones fueron secundarias a S. aureus (65 %), de estas fueron por Stafilococo aureus meticilino sensible (SAMS) el 38,9 % y por Stafilococo aureus meticilino resistente (SAMR)el 26,4 %. El tratamiento antibiótico empírico y el tratamiento definitivo se basó en cefalosporinas de primera generación en 83 % y 52,7% de los casos, respectivamente. La principal complicación fue la sepsis en 18 (25 %) pacientes. Conclusiones: se debe tener un alto índice de sospecha, no todos los pacientes se presentan con síntomas o signos típicos. El patógeno principal es el Staphylococcus aureus. En los últimos 10 años ha aumentado la incidencia de las infecciones por SAMR en nuestra institución en relación con estudios previos. Notamos una demora en el diagnóstico y, por ende, en el inicio del tratamiento.


SUMMARY Introduction: The main pathogen in osteoarticular infections is Staphylococcus aureus. The recommended treatment schemes are based on American or European literature, there are no data from local studies. The purpose of this study is to know the epidemiological profile in osteoarticular infections of the San Vicente Fundación children's hospital (Medellín/Colombia) and the characteristics of the affected patients. Materials and methods: Retrospective review of histories of patients between 0 and 15 years old with a diagnosis of osteoarticular infection in the San Vicente Fundación children's hospital detailing demographic variables, pathology and relevant antecedents to characterize the epidemiological profile of osteoarticular infections in the hospital. Results: We identified 72 patients with osteoarticular infection. The most common septic arthritis infection (40%) followed by acute osteomyelitis (37%), the most affected joint was the hip (18%) and the most affected bone was the tibia (31%). The majority of infections were secondary to S. aureus (65%) of which were by SAMS 38.9% and by SAMR 26.4%. Empirical as well as definitive antibiotic treatment was based on first generation cephalosporins 83% and 52.7% respectively. The main complication was sepsis in 18 (25%) patients. Conclusions: There must be a high index of suspicion, not all patients present with typical symptoms and / or signs. The main pathogen Staphylococcus aureushas increased the incidence of MRSA infections in our institution in the last 10 years in relation to previous studies. We note delay in diagnosis and therefore in the start of treatments.

ABSTRACT

Las betalactamasas de espectro extendido (BLEE) son enzimas producidas por bacilos gram negativos capaces de hidrolizar las cefalosporinas de amplio espectro y los monobactámicos. La mayoría pertenece a la familia de Enterobacteriae, tales como Klebsiella pneumoniae y Escherichia coli: Sin embargo, se asocian también con otras bacterias como Proteus, Serratia, Salmonella, Pseudomonas aeruginosa y Acinetobacter. Las enterobacterias productoras de carbapenemasas no sólo han sido aisladas en el ambiente hospitalario, sino que también provienen de la comunidad. Se presenta una paciente de sexo femenino con antecedentes de sida y osteomielitis secundaria a artritis séptica producida por una Klebsiella pneumoniae BLEE de la comunidad. Un tratamiento oportuno y eficaz puede evitar la opción quirúrgica, disminuyendo la morbimortalidad asociada con esta afección


Extended-spectrum beta-lactamases (ESBL) are enzymes produced by gram-negative rods capable of hydrolyzing broad-spectrum cephalosporins and monobactams. Most belong to the Enterobacteriae family, such as Klebsiella pneumoniae and Escherichia coli. However, they are also associated with other bacteria such as Proteus, Serratia, Salmonella, Pseudomonas aeruginosa and Acinetobacter. Carbapenemase-producing Enterobacteriaceae have not only been isolated from the hospital environment, but also from the community. We present a female patient with a history of AIDS and secondary osteomyelitis to septic arthritis caused by a community Klebsiella pneumoniae ESBL. It is concluded that a timely and effective treatment can avoids the surgical option, reducing the morbidity and mortality of this condition.

ABSTRACT

Resumen La enfermedad granulomatosa crónica (EGC) es una inmunode-ficiencia primaria poco frecuente. Se caracteriza por una alteración en la función de los fagocitos, causando infecciones recurrentes bacterianas y fúngicas. Presentamos el caso clínico de un niño con una osteomielitis multifocal por Serratia marcescens , microorganismo infrecuente como causa de infecciones óseas en niños, aunque asociado a la EGC. El estudio de infecciones con presentación clínica y agentes inhabituales deben hacer sospechar una EGC. Su diagnóstico precoz en la vida, así como el tratamiento antimicrobiano oportuno y el uso posterior de una profilaxis antimicrobiana adecuada logrará evitar recurrencias infecciosas y secuelas.


Abstract Chronic granulomatous disease (CGD) is a rare primary immuno-deficiency. It is characterized by an alteration in the function of phagocytes causing recurrent bacterial and fungal infections. This is a case report of a child with multifocal osteomyelitis by Serratia marcescens, an infrequent as a cause of bone infections, although associated with CGD. The study of infections with clinical presentation and unusual agents should lead to suspicion of CGD. The diagnosis early in life, as well as timely antimicrobial treatment and the subsequent antimicrobial prophylaxis will avoid infectious recurrences and sequelae.

ABSTRACT

El manejo de pseudoartrosis infectadas, osteomielitis y defectos óseos representa un reto enorme para el cirujano ortopedista. Hace diez años, Masquelet presentó la técnica de inducción de membrana como alternativa al manejo de las complicaciones mencionadas arriba con excelentes tasas de consolidación y erradicación del proceso infeccioso. Estudiamos una de serie de 14 casos, prospectiva, con seguimiento clínico y radiológico mínimo de 2 años (enero 2015-diciembre 2018), donde evaluamos múltiples variables en pacientes a quienes se les realizó el protocolo de Masquelet. Obtuvimos una tasa de consolidación de 85,7% (12/14). Con un tiempo promedio para alcanzarla de 6,1 meses (3-9m). Todos los pacientes que lograron la consolidación se encontraban libres de infección al final del seguimiento. Por su reproducibilidad y alta tasa de consolidación, consideramos la técnica de inducción de membrana, como una excelente opción en el manejo de pseudoartrosis infectadas complejas(AU)


The management of infected nonunions, osteomyelitis, and bone defects represents an enormous challenge for the orthopedic surgeon. Ten years ago, Masquelet presented the membrane induction technique as an alternative to the management of the complications afore mentioned with excellent rates of consolidation and eradication of the infectious process. We prospectively studied a series of 14 cases, with a clinical and radiological follow-up of at least 2 years (january 2015-december 2018). Where we evaluated multiple variables in patients who underwent the Masquelet protocol. We obtained a consolidation rate of 85.7% (12/14). With an average time to reach it of 6.1 months (3-9m). All patients who achieved union were free of infection at the end of follow-up. Due to its reproducibility and high consolidation rate, we consider the membrane induction technique an excellent option in the management of complex infected nonunions(AU)

ABSTRACT

Resumen Las infecciones por bacterias gramnegativas del género Myroides son muy poco frecuentes y generalmente afectan la piel y tejidos blandos de pacientes con algún grado de inmunocompromiso. Presentamos un caso de una mujer de 23 años, con antecedentes de mielomeningocele operado y pie bot, que cursó con una infección profunda de la extremidad inferior derecha por Myroides odoratimimus. La identificación de especie se realizó con técnica de MALDI-TOF. El tratamiento fue inicialmente con meropenem y ajustado a ciprofloxacina, junto con realizar una amputación supramaleolar derecha.


Abstract Infections due to Gram-negative bacteria of the genus Myroides are very rare and generally affect the skin and soft tissues of patients with some degree of immunocompromise. We present a case of a 23-year-old patient with a history of myelomeningocele surgically resolved at 3 years of age and bot foot, who presented with a deep infection of the right lower extremity by Myroides odoratimimus. The species identification was carried out with MALDI-TOF and the treatment was initially carried out with meropenem and finally then ciprofloxacin, in addition to right supramaleolar amputation.

ABSTRACT

Resumen Staphylococcus aureus coloniza la nasofaringe en un tercio de los individuos sanos y además es causante de infecciones graves en pediatría, como endocarditis, neumonía e infecciones osteoarticulares. Posee varios mecanismos de virulencia, siendo la leucocidina de Panton Valentine (LPV) uno de ellos, una exotoxina que causa muerte celular. Su producción está comúnmente relacionada con Staphylococcus aureus resistente a meticilina (SARM) e infecciones pulmonares y musculo-esqueléticas graves. Sin embargo, la producción de LPV no es exclusiva de SARM. Se presentan dos casos clínicos de pacientes con infección por Staphylococcus aureus sensible a meticilina productora de esta exotoxina.


Abstract Staphylococcus aureus colonizes the nasopharynx in one third of healthy individuals and is also responsible for several infections in pediatrics such as endocarditis, pneumonia and osteoarticular infections. It has several virulence mechanisms, such as Panton Valentine leukocidin (PVL), which is an exotoxin that causes cell death. It is commonly related to methicillin-resistant Staphylococcus aureus (MRSA) and more serious pulmonary and musculoskeletal infections. However, PVL is not exclusive to MRSA. Two clinical cases of patients with infection by methicillin-sensitive Staphylococcus aureus producing this exotoxin are presented.

ABSTRACT

Resumen La infección del muñón después de amputaciones traumáticas tiene una prevalencia hasta del 34%. Las bacterias más frecuentemente aisladas son Staphylococcus aureus, Enterobacterales como Escherichia coli; Pseudomonas aeruginosa, entre otras. Estas infecciones ocurren por la inoculación directa en el momento del trauma o por gérmenes nosocomiales; la realización de curaciones de las heridas con emplastos vegetales es una práctica aún frecuente en zonas rurales de nuestro país pero su relación con infección del sitio operatorio ha sido poco explorada en la literatura. Leuconostoc spp. es un coco Gram positivo encontrado en territorio agrícola y utilizado en la industria de alimentos. Se presenta un caso de infección de un muñón transfemoral por Leuconostoc, después de una amputación traumática del miembro inferior en una paciente previamente sana con una posible asociación a curaciones con emplastos vegetales.


Abstract Infection of a traumatic amputation stump has a prevalence of 34%. The most common bacteria isolated are Staphylococcus aureus, Pseudomonas aeruginosa and Enterobacterales such as Escherichia coli. These infections occur by direct inoculation in the moment of the trauma or by nosocomial germs. Infections secondary to manipulation of the wounds with vegetable plasters have few case reports in the literature. Leuconostoc spp. is a Gram-positive coccobacillus commonly found in agricultural territory and used in the food industry. There are few case reports in the literature about bone infections by Leuconostocs pp. We present a case of an infection of the operative site of a transfemoral stump by Leuconostoc spp. after a traumatic amputation of the lower limb in a previously healthy patient who had a possible association to cures with vegetable plasters.

ABSTRACT

Introducción: La osteomielitis mandibular crónica es considerada como una infección odontogénica que cursa con tumefacción de la cara, limitación de la abertura bucal y dolor. Pocas veces es tratada a través de gammagrafías con fijación a ciprofloxacino con la consiguiente obtención de resultados efectivos. Objetivo: Describir un caso clínico de osteomielitis mandibular crónica tratada con terapia antibiótica y quirúrgica. Presentación de caso: Paciente femenina de 63 años de edad que acudió al servicio de estomatología del Hospital María Auxiliadora, Lima, Perú; con un historial de tres meses de hinchazón creciente a nivel del borde inferior izquierdo de la mandíbula desde que le realizaron una extracción dentaria. Los exámenes tomográficos, gammagrafía, biopsia y antibiograma confirmaron la osteomielitis y la susceptibilidad bacteriana. La decorticación, debridamiento, exodoncia y la administración de metronidazol más vancomicina por dos meses permitió la remisión del cuadro. Conclusiones: El seguimiento clínico de dos años y las gammagrafías de evaluación permitieron verificar la presencia de regeneración ósea y ausencia de focos de reactivación. La osteomielitis crónica puede ser provocada por restos de exodoncias dentarias. Su diagnóstico y seguimiento clínico requiere de múltiples exámenes y controles a largo plazo(AU)


Introduction: Chronic mandibular osteomyelitis is considered to be an odontogenic infection manifesting as facial tumefaction, limited mouth opening and pain. It is not often enough treated with ciprofloxacin fixation gammagraphies with the consequent achievement of effective results. Objective: Describe a clinical case of chronic mandibular osteomyelitis treated with antibiotic and surgical therapy. Case presentation: A female 63-year-old patient attends the dental service at María Auxiliadora Hospital in Lima, Peru, with a history of three-months' swelling of the lower left edge of her mandible upon performance of a dental extraction. Tomographic examination, gammagraphy, biopsy and antibiograms confirmed the presence of osteomyelitis and bacterial susceptibility. Decortication, debridement, exodontia and administration of metronidazole plus vancomycin for two months led to remission of the patient's status. Conclusions: Two-year clinical follow-up and evaluation gammagraphies made it possible to verify the presence of bone regeneration and the absence of reactivation foci. Chronic osteomyelitis may be caused by remains of dental exodontias. Its diagnosis and clinical follow-up require a large number of long-term tests and controls(AU)
