Características microbiológicas de los pacientes con úlcera del pie diabético / Microbiologic characteristics of patients with diabetic foot ulceration

RESUMEN Introducción: Las infecciones de las úlceras del pie diabético son comunes, complejas, de alto costo y constituyen la principal causa de amputación no traumática de las extremidades inferiores. Objetivo: Identificar los microorganismos aislados para estimar tanto la sensibilidad a los antibióticos como la coincidencia entre el tratamiento empírico y los resultados microbiológicos en pacientes con úlceras del pie diabético. Métodos: Se realizó una investigación descriptiva-retrospectiva. La población de estudio estuvo constituida por 210 pacientes ingresados en el Hospital Universitario Clínico Quirúrgico "Comandante Faustino Pérez Hernández" de Matanzas entre junio de 2017 y junio de 2020. Las variables de salida fueron la frecuencia y el tipo de germen, la cantidad de gérmenes por úlcera, la sensibilidad para cada tipo de antibiótico, y el porcentaje de coincidencia entre el tratamiento empírico y el resultado microbiológico. Resultados: Se identificaron 259 gérmenes y se observaron 1,23 gérmenes por úlcera. El 62,5 por ciento de los gérmenes encontrados fueron Gram negativos, pero el germen más representado fue el Staphylococcus aureus. El 58,8 por ciento de los Staphylococcus aureus se mostraron resistentes a la meticillin. La vancomicina y el linezolid resultaron efectivos en el 100 por ciento de los Gram positivos. La amikacina fue el antibiótico más efectivo para los Gram negativos. Se observó coincidencia entre el tratamiento empírico y el resultado del antibiograma en el 27,6 por ciento de los pacientes. Conclusiones: Resulta necesario un apropiado diagnóstico microbiológico de las úlceras del pie diabético para identificar los gérmenes presentes en las lesiones y diseñar algoritmos de terapia antimicrobiana adecuados(AU)

ABSTRACT Introduction: Diabetic foot ulcer infections are common, complex, high cost and are the leading cause of non-traumatic lower extremity amputation. Objective: To identify the microorganisms isolated to estimate both the sensitivity to antibiotics and the coincidence between empirical treatment and microbiological results in patients with diabetic foot ulcers. Methods: A descriptive-retrospective investigation was performed. The study population consisted of 210 patients admitted to the University Hospital "Comandante Faustino Pérez Hernández" of Matanzas between June 2017 and June 2020. The output variables were the frequency and type of germ, the number of germs per ulcer, the sensitivity for each type of antibiotic, and the percentage of coincidence between the empirical treatment and the microbiological result. Results: A total of 259 germs were identified and 1.23 germs per ulcer were observed. The 62.5 percent of the germs found were Gram negative, but the most represented germ was Staphylococcus aureus. Of the Staphylococcus aureus, 58.8 percentwere resistant to methicillin. Vancomycin and linezolid were effective in 100 percent of Gram positives. Amikacin was the most effective antibiotic for Gram-negatives. Agreement between empirical treatment and antibiogram result was observed in 27.6 percent of patients. Conclusions: An appropriate microbiological diagnosis of diabetic foot ulcers is necessary to identify the germs present in the lesions and to design adequate antimicrobial therapy algorithms(AU)

Introducción: Las úlceras flebostáticas constituyen una patología importante en la práctica médica diaria en todos los niveles de asistenciales; después del dolor y del edema, las úlceras de los miembros inferiores representan el tercer problema más común en las consulta de angiología. Objetivo: Caracterizar los gérmenes bacterianos aislados con frecuencia en las úlceras flebostáticas de los pacientes ingresados. Métodos: Se realizó un estudio descriptivo retrospectivo de corte transversal en 60 pacientes ingresados por diagnóstico de úlceras flebostáticas entre julio de 2016 y junio de 2017. A todos se les hizo cultivo microbiológico de la lesión con el respectivo antibiograma. Se tuvieron en cuenta las variables: tipo de úlcera flebostática, gérmenes bacterianos aislados, antibióticos analizados in vitro y patrón de sensibilidad antibiótica. Se calcularon las frecuencias absolutas y relativas. Resultados: Se encontró un predominio de úlceras varicosas (67 por ciento). El germen bacteriano que más se aisló fue Pseudomas spp. (41,7 por ciento), con más frecuencia en las úlceras varicosas que en las postrombóticas (47,5 por ciento vs. 30 por ciento). Los mejores porcentajes de sensibilidad in vitro se mostraron ante los siguientes antibióticos: Clindamicina (100 por ciento), Tobramicina (79,2 por ciento), Ciprofloxacino (78,4 por ciento), Amikacina (68,4 por ciento), Cotrimoxazol (68,2 por ciento), Cefepime (67,6 por ciento), Doxiciclina (66,7 por ciento), Cloranfenicol (60 por ciento), Meropenem (62,1 por ciento), Penicilina G (57 por ciento) y Aztreonam (55,9 por ciento). Conclusiones: Pseudomas spp. fue el germen bacteriano que más se aisló en los pacientes con úlceras varicosas y postrombóticas; además, se manifestó sensibilidad a 11 de los 23 antibióticos que se probaron in vitro en más del 50 por ciento de los aislados a los que se enfrentaron(AU)

Introduction: Phlebostatic ulcers are an important pathology in daily medical practice at all levels of care; after pain and edema, lower limb ulcers are the third most common problem in angiology consultations. Objective: Characterize frequently isolated bacterial germs in the phlebostatic ulcers of admitted patients. Methods: A descriptive, cross-sectional, retrospective study was conducted in 60 patients admitted due to a diagnosis of phlebostatic ulcers from July 2016 to June 2017. It was made a microbiological cultivation of the lesion with the respective antibiogram to all the patients. Variables were taken into account, like: type of phlebostatic ulcer, isolated bacterial germs, antibiotics tested in vitro and antibiotic sensitivity pattern. The absolute and relative frequencies were calculated. Results: A predominance of varicose ulcers (67 percent) was found. The most isolated bacterial germ was Pseudomasspp. (41.7 percent), and it was more often in varicose ulcers than in post-thrombotic ulcers (47.5 percent vs. 30 percent). The best percentages of in vitro sensitivity were shown against the following antibiotics: Clindamycin (100 percent), Tobramycin (79.2 percent), Ciprofloxacin (78.4 percent), Amikacin (68.4 percent), Cotrimoxazol (68.2 percent), Cefepime (67.6 percent), Doxycycline (66.7 percent), Chloramphenicol (60 percent), Meropenem (62.1 percent), Penicillin G (57 percent), Aztreonam (55.9 percent). Conclusions: Pseudomasspp. was the most isolated bacterial germ in patients with varicose and post-thrombotic ulcers; in addition, sensitivity was present in 11 of the 23 antibiotics that were tested in vitro in more than 50 percent of the isolates they faced(AU)

Infecciones del tracto urinario en neonatos sin explicación. Hiperbilirrubinemia: Prevalencia y predictivo factores de riesgo / Urinary tract infections in unexplained neonatal hyperbilirubinemia: Prevalence and predictive risk factors

Introduction: Urinary tract infections (UTIs) are widespread clinical disorder among early neonates. Neonates with UTIs were susceptible to higher rates of morbidity and mortality, particularly when presented with hyperbilirubinemia. Early diagnosis may help in complete recoveryrather than being threatened in terms of complications. The study aimed at determining the prevalence and predictive risk factors of UTIs in neonates with an unexplained hyperbilirubinemia. Method: A cross-sectional study was carried out in the NICU of Aswan University Hospital, Egypt from August 2018 to February 2019. The study was conducted on 140 newborns who were diagnosed with indirect hyperbilirubinemia in the first 4 weeks of life after exclusion of unrelated criteria. Demographic and clinical data were collected by an interview questionnaire. Biochemical markers including bilirubin level, CBC, urine analysis and urine cultures and sensitivity were determined. Results: The prevalence rate of UTIs in the studied newborns was 25%. Escherichia -coli was the dominant organism isolated. Amikacin was the most common antibiotic sensitive to the isolates. There was a significant difference between the UTI positive and negative neonates in the univariate analysis regarding some studied variables. While, an increase in the number of WBCs in the blood (OR = 6.90, P = 0.001), small for gestational age (OR = 4.07, P = 0.021), prolonged phototherapy (OR = 3.50, P = 0.034), and presence of maternal complications (OR = 2.92, P = 0.001) were statistically associated with a positive urine culture in multivariate analysis. Conclusions and recommendations: The prevalence rate of UTIs was 25%. The study indicated the importance of routine screening of UTI (urine culture) as part of the clinical assessment of unexplained hyperbilirubinemia in neonates with an increase in the number of WBCs in their blood, small for gestational age, prolonged duration of phototherapy, and neonates born from mothers who had a history of obstetric complications

Multirresistencia de Escherichia coli y Klebsiella pneumoniae provenientes de pacientes con infección del tracto urinario adquirida en la comunidad / Escherichia coli and Klebsiellap neumoniae multiresistance from patients with urinary tract infection acquired in the community

Introducción: El incremento de la multirresistencia bacteriana constituye un problema de salud pública a nivel internacional. Objetivos: Determinar la susceptibilidad antimicrobiana y los patrones de multirresistencia en cepas de Escherichia coli y Klebsiella pneumoniae aisladas de urocultivos. Métodos: Se realizó un estudio descriptivo retrospectivo en el Centro Municipal de Higiene, Epidemiología y Microbiología, municipio Güines, provincia Mayabeque, Cuba, en el periodo comprendido de enero a diciembre de 2017. El estudio incluyó 250 cepas de Escherichia coli y 62 de Klebsiella pneumoniae aisladas e identificadas de muestras de orina de pacientes con infección del tracto urinario adquirida en la comunidad. La susceptibilidad antimicrobiana fue evaluada con el método de difusión en agar empleado la técnica de Kirby Bauer. Resultados: En Escherichia coli se observó niveles de resistencia superiores al 60 por ciento a los antimicrobianos ácido nalidíxico, cefotaxima, trimetoprim - sulfametoxazol y ceftazidima. La nitrofurantoína y la amikacina presentaron 88,8 por ciento y 83,8 por ciento de efectividad, respectivamente. Se apreció en Klebsiella pneumoniae altos valores de resistencia a ceftazidima, trimetoprim - sulfametoxazol y ácido nalidíxico. Amikacina, presentó niveles de sensibilidad de un 71 por ciento. La resistencia a las cefalosporinas de tercera generación se detectó en 78 (31,2 por ciento) de Escherichia coli y 26 (41,9 por ciento) de Klebsiella pneumoniae. De los aislados de Escherichia coli 143 (57,2 por ciento) y Klebsiella pneumoniae 35 (56,4 por ciento) presentaron multidrogoresistencia. Conclusiones: Existe la circulación de cepas resistentes a cefalosporinas de tercera generación y multidrogorresistentes causantes de infecciones de las vías urinarias adquiridas en la comunidad y se informa sobre los antibióticos (nitrofurantoína y amikacina) que podrían ser utilizados para combatirlas de forma empírica en esta área geográfica(AU)

Introduction: The increase of bacterial multiresistance constitutes a public health problem at the international level. Objectives: To determine antimicrobial sensitivity and multiresistance patterns in strains of Escherichia coli and Klebsiellapneumoniae isolated from urine cultures. Methods: A retrospective, descriptive study was conducted at the Municipal Center for Hygiene, Epidemiology and Microbiology, Güines municipality, Mayabeque Province, Cuba, in the period from January to December, 2017. The study included 250 Escherichia coli and 62 Klebsiellapneumoniae strains isolated and identified from urine samples from patients with urinary tract infection acquired in the community. Antimicrobial sensitivity was evaluated with the method of diffusion in agar using Kirby Bauer´s technique. Results: In Escherichia coli, resistance levels higher than the 60% were observed in antimicrobial nalidixic acid, cefotaxime, trimethoprim-sulfamethoxazole and ceftazidime. Nitrofurantoin and amikacin presented 88.8 percent and 83.8 percent of effectiveness, respectively. High values of resistance to ceftazidime, trimethoprim-sulfamethoxazole and nalidixic acid were present in Klebsiellapneumoniae. Amikacin presented sensitivity levels of 71 percent. Resistance to third-generation cephalosporins was detected in 78 (31.2 percent) of Escherichia coli and 26 (41.9 percent) Klebsiellapneumoniae. From the Escherichia coli and Klebsiellapneumoniae isolates, 143 (57.2 percent) and 35 (56.4 percent),respectively, presented multidrug resistance. Conclusions: There is circulation of strains which are resistant to third generation cephalosporins and multidrug resistants that cause urinary tract infections acquired in the community and there are reports on antibiotics (nitrofurantoin and amikacin) that might be used to combat them empirically in this geographical area(AU)

Uso de la amikacina como profilaxis en pacientes sometidos a prostatectomía / Use of amikacin as prophylaxis in patients undergoing prostatectomy / Uso de amicacina como profilaxia em pacientes submetidos à prostatectomia

Resumen 17. El objetivo de este artículo es presentar la mejor evidencia científica disponible sobre el uso de la amikacina como profilaxis en pacientes sometidos a prostatectomía. La indicación de amikacina en cirugías tipo prostatectomías se remite al uso profiláctico, razón por la cual surge la inquietud sobre el beneficio de la administración del medicamento en estos pacientes tomando en cuenta que, entre los efectos adversos, se evidencia nefrotoxicidad y ototoxicidad principalmente en personas adultas mayores o con problemas renales previos. Se utilizó la metodología de práctica clínica basada en la evidencia (PCBE), partiendo de una pregunta clínica para posteriormente hacer las búsquedas electrónicas en bases de datos como: MEDLINE, Google académico y Cochrane Library Plus. Después de establecer los criterios de inclusión y exclusión y análisis crítico, se seleccionó cuatro documentos que se relacionan con la respuesta a la pregunta planteada. Los resultados para el análisis crítico fueron revisados minuciosamente a través de la plataforma informática FCL 2.0 con las plantillas correspondientes. La evidencia señala que ningún estudio respondió directamente a la pregunta clínica planteada, las investigaciones analizadas no demuestran evidencia que confirme que el uso profiláctico de la amikacina sea beneficioso en pacientes intervenidos quirúrgicamente. Se concluye que no se encuentró evidencia significativa que respalde el uso profiláctico de la amikacina para disminuir las infecciones. La profilaxis se enfoca en administrar en pacientes sometidos a procedimientos quirúrgicos urológicos como primera elección un antibiótico de menor espectro, ya que para administrar amikacina hay que cumplir con los lineamientos institucionales establecidos según la condición de cada usuario, tomando en cuenta los resultados de las pruebas de función renal pre y post administración.

Abstract 21. The aim of this article is to present the best available scientific evidence on the use of amikacin as prophylaxis in patients undergoing prostatectomy. The indication of amikacin in prostatectomy-type surgeries refers to prophylactic use, which is why the concern about the benefit of administering the drug in these patients arises, taking into account that, among the adverse effects, nephrotoxicity and ototoxicity are evidenced mainly in people older adults or with previous kidney problems. We used the evidence-based clinical practice methodology (PCBE), based on a clinical question to later perform the electronic searches in databases such as: MEDLINE, Google academic and Cochrane Library Plus. After establishing the inclusion and exclusion criteria and critical analysis, four documents were selected that relate to the answer to the question posed. The results for the critical analysis were thoroughly reviewed through the FCL 2.0 computer platform with the corresponding templates. The evidence indicates that no study directly responded to the clinical question posed, the investigations analyzed do not demonstrate evidence confirming that the prophylactic use of amikacin is beneficial in patients undergoing surgery. It was concluded that no significant evidence was found to support the prophylactic use of amikacin to reduce infections. Prophylaxis focuses on administering patients with urological surgical procedures as first choice a lower spectrum antibiotic, since to administer amikacin it is necessary to comply with established institutional guidelines according to the condition of each user, taking into account the results of the tests of renal function pre and post administration.

Resumo 25. O objetivo deste artigo é apresentar as melhores provas disponíveis sobre o uso da doença como profilaxia em pacientes com uma prostatectomia. A indicação de amicacina em cirugias tipo prostatectomia é remediada com o uso de profiláctico, a razão pela investigação surge sobre o benefício da administração do medicamento em estágios, a tomada de controle, entre os efetivos adversos, a evidência nefrotoxicidad e ototoxicidad principalmente em personas adultas mayores o com problemas renales previos. Use a metodologia de prática clínica baseada na evidência (PCBE), partindo de uma clínica pré-existente para o futuro sobre as bússulas electrónicas em bases de dados como: MEDLINE, Google académico e Biblioteca Cochrane Plus. Depois de estabelecer os critérios de inclusão e exclusão e análise crítica, selecione o documento que se relaciona com a resposta à pregunta plantada. Os resultados para a análise crítica foram revisados ​​minuciosamente através da plataforma informática FCL 2.0 com os plantillas correspondentes. A evidência é que o exame é respondido diretamente à consulta clínica plantada, as investigações não demonstram evidências que confirmam o uso profiláctico da amidação do mar em pacientes intervencionados quirúrgicamente. Se concluye que não há provas de que são importantes o uso do termo profiláctico da amicina para disminuir as infecciones. A profilaxia do enfarte na administração de doentes é um procedimento quirúrgico urológico como a primeira eleição do antibiótico de menor espectro, o que ajuda a administrar o feno que cumplir com os lineamentos institucionais estabelecidos segundo a condição de cada um, tomando os resultados dos exames de función renal pré y pós administración.

A case of atypical nocardia asteroides sclerouveitis resistant to fourth-generation fluoroquinolones / Um caso atípico de esclero-uveíte por Nocardia Asteroides resistente a fluorquinolona de quarta-geração

ABSTRACT We describe an unusual case of Nocardia spp scleritis in a health girl resistant to topical fourth-generation fluoroquinolones. Clinically, there was only partial response of the scleritis to initial therapy. Treatment was changed to meropenem intravenously and topical amikacin. Following several weeks of antibiotic treatment, the patient's infection resolved but her vision was reduced to no light perception. Nocardia asteroides must be considered as a possible agent in cases of necrotizing scleritis in patients without a clear source. Antibiotic sensitivity testing has a definitive role in view of the resistance to these new medications.

RESUMO Nós descrevemos um raro caso de esclerite por Nocardia spp em uma criança sadia resistente a utilização tópica de fluorquinolona de quarta-geração. Clinicamente, a paciente apresentou apenas uma resposta parcial do quadro de esclerite a terapêutica inicial. O tratamento foi então modificado para meropenem intravenoso e amicacina tópica. Após várias semanas de tratamento com antibiótico, o quadro infeccioso regrediu porém a visao da pacientes evoluiu para perda da percepção luminosa. Em casos de esclerite necrotizante em pacientes sem fatores de risco aparente é necessário considerer a Nocardia Asteroides como possível agente causador. Os testes de sensibilidade medicamentosa apresentam importância significativa em virtude do aparecimento de resistência aos novos medicamentos.

Listeria monocytogenes meningitis in an immunocompetent adult: a case report / Listeria monocytogenes meningite em um adulto imunocompetente: relato de caso

Listeria monocytogenes (L. monocytogenes) is an uncommon cause of bacterial meningitis in immunocompetent adults. Patients with immunosuppression are at increased risk of developing serious invasive diseases, particularly meningitis. We describe a case of meningitis caused by L. monocytogenes in an immunocompetent and previously healthy 34-year-old adult. The patient received treatment with intravenous ampicillin plus amikacin and made a full recovery. L. monocytogenes should be suspected in immunocompetent adults with bacterial meningitis who fail to respond to empirical antibiotic treatment.

Listeria monocytogenes (L. monocytogenes) é uma causa rara de meningite bacteriana em adultos imunocompetentes. Pacientes com imunossupressão têm maior risco de desenvolver graves doenças invasivas, especialmente a meningite. Descrevemos um caso de meningite por L. monocytogenes em um adulto imunocompetente e previamente sadio com idade de 34 anos. O paciente recebeu tratamento com ampicilina intravenosa mais amicacina e fez uma recuperação completa. L. monocytogenes deve ser suspeitada em imunocompetentes adultos com meningite bacteriana que não respondem ao tratamento antibiótico empírico.

Diabetes mellitus and spinal epidural abscess: clinical or surgical treatment? / Diabetes melito e abscesso epidural espinhal: tratamento clínico ou cirúrgico?

Spinal epidural abscess (SEA) is an uncommon condition and its most important predisposing factor is diabetes mellitus. Although the treatment of choice is prompt surgical abscess evacuation, followed by antibiotic therapy, successful conservative treatment of SEA has been reported in some cases. We describe a SEA case in a 23-year old white woman with diabetes for 14 years, who was successfully treated only with antibiotics, and achieved full recovery at the fourth month of follow-up.

O abscesso epidural espinhal (AEE) é uma doença incomum e o diabetes melito é o seu fator predisponente mais importante. O tratamento de escolha é a imediata drenagem cirúrgica, seguida de antibioticoterapia, entretanto, casos já foram relatados em que o AEE foi tratado clinicamente com sucesso. Descrevemos um caso de AEE em um paciente diabético tratado satisfatoriamente com uso isolado de antibióticos e que evoluiu com recuperação total no quarto mês de seguimento.

Avaliação da resistência da Escherichia coli frente a Ciprofloxacina em uroculturas de três laboratórios clínicos de Aracaju-SE / Escherichia coli: evaluation of its resistance by Ciprofloxacinin in urine culture of three clinical laboratories of Aracaju-SE

Esse artigo objetivou avaliar a resistencia da Escherichia coli ao antibiotico ciprofloxacina a partir dos resultados de uroculturas e seus antibiogramas no municipio de Aracaju-SE, no ano de 2007. Para tal, utilizou-se os registros do setor de microbiologiade dois laboratorios ambulatoriais e um hospitalar. Foram executadas no periodo em estudo, 3.646 uroculturas, sendo 2.629 negativas e 1.017 positivas. Dentre as positivas (64,1%) foram para Escherichia coli, seguida de Enterobacter spp. (10,7%) Klebsiella spp. (10,1%), Staphylococcus spp. (7,3%), Proteus spp. (5,4%), Morganella spp. (1%), Serratia spp. (0,8%) e Pseudomonas spp. (0,7%). Jaos antibioticos utilizados nas uroculturas positivas foram: ciprofloxacina (98,9 %), ceftriaxona (97,5%), amicacina (95,3%), ampicilina (94,9%), ceftazidima (94,7%), nitrofurantoina (90,3%) e tobramicina (90,1%). Neste estudo a Escherichia coli mostrou uma resistencia de 21,3%. Mediante esse resultado sugere-se que, ao ser administrado ciprofloxacina para tratamento de infeccoes urinarias por Escherichia coli em Aracaju-SE, ele seja realizado com bastante parcimonia.

This article aimed to evaluate the resistance of the Escherichia coli to the ciprofloxacin antibiotic based on urine cultures results and antibiograms in Aracaju-SE of 2007. To reach this goal, records from the Microbiology sector of two ambulatory laboratories and one hospital laboratory were used. During this period of studies, 3.646 urine cultures were accomplished, of which 2.629 were negative and 1.017 were positive. The samples were positive for Escherichia coli (64,1%), followed by Enterobacter spp. (10,7%), Klebsiella spp. (10,1%), Staphylococcus spp (7,3%), Proteus spp. (5,4%), Morganella spp. (1%), Serratia spp. (0,8%) and Pseudomonas spp. (0,7%). The antibiotics used in positive urine cultures were ciprofloxacin (98,9%), ceftriaxone (97,5%), amikacin (95,3%), ampicilin (94,9%), ceftazidime (94,7%), nitrofurantoin (90,3%) and tobramycin (90,1%). In this study, Escherichia coli showed a resistance of 21,3%. These results suggest that the ciprofloxacin administration for treating urinary infections by Escherichia coli should bedone with frugality in Aracaju-SE.

Aeromonas caviae septicemia in immunocompetent gastrointestinal carriers

Aeromonas caviae strains have been isolated from blood and stool cultures of three immunocompetent patients, residents of Northern India, who presented with community acquired septicemia without any recent history of diarrhea. Cell culture infectivity test performed on Hep-2 cells have shown substantial degree of invasiveness in the isolated strains. This case unleashes a possibility of asymptomatic gastrointestinal carriage of such strains of A. caviae in a very large population of India, as several areas of India have very high rates of Aeromonas induced acute diarrhea/gastroenteritis (up to 13 percent). It needs to be appraised further in India as well as other countries having high rates of Aeromonas induced acute diarrhea/gastroenteritis.

Cutaneous infection with Mycobacterium fortuitum: an unusual presentation.

Cutaneous infection with rapidly growing mycobacteria is uncommon and its diagnosis can be missed unless there is strong clinical suspicion coupled with microbiological confirmation. We report a case of localized recurrent soft tissue swelling of the foot by Mycobacterium fortuitum in a healthy adult male. The case is being reported for its uncommon clinical presentation and the associated etiological agent. The patient recovered completely following therapy with amikacin and clarithromycin.

Klebsiella pneumoniae brain abscess in two neonates.

We report two premature infants who developed multiple brain abscesses following Klebsiella pneumoniae infection. Both the cases were diagnosed by ultrasonogram (USG) and cranial tomography. Abscess had intraventricular communication in one case. One infant was managed conservatively while the other required surgical drainage.

Bacteriemia primaria por Listeria monocytogenes en paciente con cirrosis hepática: Caso clínico / Primary Listeria monocytogenes infection in a cirrhotic woman: Report of one case

L. monocytogenes infections are infrequent. Sepsis in pregnant women and newborns and central nervous system infections in the elderly are the most common clinical manifestations. We report a 61 years old woman with diabetes Mellitus and a Child B hepatic cirrhosis, admitted for persistent fever. Blood cultures were positive for Listeria monocytogenes. Cerebrospinal fluid was normal and sterile. She was treated with ampicillin and amikacin with a good response. Control blood cultures were negative. She was discharged 14 days after in good conditions.

Pyopericardium due to group D streptococcus.

Beta-hemolytic Enterococcus faecalis was isolated from the pericardial fluid obtained from a patient with pyopericardium. The patient was immunocompetent and had mild pleural effusion. He was treated with parenteral co-amoxiclav and amikacin, had underwent pericardiectomy with repeated pericardial aspiration, and recovered completely. To our knowledge, this is the first report of pyopericardium due to E. faecalis .

Experience of Comamonas Acidovorans Keratitis with Delayed Onset and Treatment Response in Immunocompromised Cornea

PURPOSE: To report 2 cases of Comamonas acidovorans keratitis in immunocompromised cornea. METHODS: A complete review of the medical records of the two cases of Comamonas acidovorans keratitis. RESULTS: We found some similarities in clinical courses of two cases. Both of them showed development of keratitis during the management with corticosteroids, delayed onset, slow response to antibiotics, and relatively less affected corneal epithelium. CONCLUSIONS: Comamonas acidovorans is known as a less virulent organism. However it can cause an indolent infection that responds slowly even to adequate antibiotics therapy in immunocompromised corneas.
