ABSTRACT

Abstract Dermoscopy is an essential in vivo diagnostic technique in the clinical evaluation of skin tumors. Currently, the same can also be said about its implications when approaching different clinical situations in Dermatology. A growing number of reports on dermatological scenarios and diseases have been published, in which dermoscopy has been of great diagnostic help. The term ‟entomodermoscopy" was coined to describe dermoscopic findings in skin infestations and also in dermatoses of infectious etiology. In part I of this article, the main dermoscopic descriptions of zoodermatoses and bacterial infections will be addressed. In many of them, such as scabies, pediculosis, myiasis, and tungiasis, it is possible to identify the pathogen and, consequently, attain the diagnosis more quickly and use the technique to follow-up therapeutic effectiveness. In other situations that will be described, dermoscopy can allow the observation of clinical findings with greater detail, rule out differential diagnoses, and increase the level of confidence in a clinical suspicion.

ABSTRACT

Os mecanismos de resistência bacteriana podem existir de maneira intrínseca ou adquirida, porém em ambos os casos podem dificultar a terapia antimicrobiana preconizada para tratamento de infecções. Este artigo tem como objetivo apresentar estudos recentes sobre o assunto. Foi realizada uma revisão da literatura sobre resistência bacteriana aos antimi- crobianos, utilizando as bases de dados MEDLINE, LILACS, Scopus e Web of Science. A busca identificou o total de 16 artigos, que foram publicados entre os anos de 2017 a 2021. A maioria dos artigos sobre Gram-negativos tratou do grupo das enterobactérias, assim como os de Gram-positivos tratou dos gêneros Staphylococcus , Enterococcus e Streptococcus. A resistência bacteriana foi encontrada em cefalosporinas, carbapenêmicos, quinolonas, aminoglicosídeos, entre outros. Em relação aos mecanismos de resistência, as ß-Lactamases de espectro estendido (ESBL), enterobactérias resistentes aos carbape- nêmicos (ERC), Staphylococcus aureus resistentes à meticilina (MRSA) e Enterococcus resistentes à vancomicina (VRE) foram relatados e observa-se que a maioria dos trabalhos corrobora que seu rastreamento visa minimizar a transmissão em instituições de saúde.


Bacterial resistance mechanisms can exist intrinsically or acquired, but in both cases they can make the antimicrobial therapy recommended for the treatment of infections difficult. This article aims to present recent studies on the subject. A literature review on bacterial resistance to antimicrobials was carried out using the MEDLINE, LILACS, Scopus and Web of Science databases. The search identified a total of 16 articles, which were published between 2017 and 2021. Most articles on Gram-negatives dealt with the enterobacteria group, as well as Gram-positive articles from the Staphylococcus, Enterococcus and Streptococcus genera. Bacterial resistance was found in cephalosporins, carbapenems, quinolones, aminoglycosides, among others. Regarding resistance mechanisms, Extended Spectrum Beta-Lactamases (ESBL), Carbapenem-Resistant Enterobacteria (ERC), Methicillin- Resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococcus (VRE) have been reported and it is observed that most works corroborate that its tracking aims to minimize transmission in health institutions.

ABSTRACT

Objetivo: Presentar un caso clínico en el que el paciente cursa impétigo que podría estar relacionado con el uso de mascarillas faciales por un tiempo prolongado. Caso clínico: Se reporta el tratamiento y la evolución de un caso clínico en un paciente adulto que consultó en un centro clínico privado por la presencia de lesiones vesiculares en la región labial superior con aumento de volumen generalizado en ambos labios. El cuadro clínico es compatible con infección por impétigo y herpes zóster asociado al uso prolongado de una mascarilla de tela. Se describe la importancia del empleo correcto de estas mascarillas que se están usando como medida de protección personal en el contexto de la pandemia por COVID-19, ya que las mismas pueden contribuir a generar infecciones faciales si no se mantiene una higiene apropiada (AU)


Aim: To present a clinical case in which the patient has impetigo that could be related to the use of facial masks for a long time. Clinical case: The treatment and evolution of a clinical case of an adult patient who attended a private clinical centre due to the presence of vesicular lesions in the upper labial region with generalized increase volume in both lips is reported. The clinical presentation is compatible with impetigo and herpes zoster infection associated with prolonged use of a cloth mask. The importance of the correct use of cloth masks that are being used as a personal protection measure in the context of the COVID-19 pandemic is described, since they can contribute to facial infections if proper hygiene is not observed (AU))

ABSTRACT

Introducción: la Chlamydia trachomatis es la principal causa de infecciones bacterianas de transmisión sexual a nivel mundial. Se estima que cada año se producen 131 millones de casos. Cursa de manera asintomática, pero la infección ascendente en mujeres puede conducir a la enfermedad inflamatoria pélvica, embarazo ectópico e infertilidad. Objetivo: determinar la prevalencia de C. trachomatis en mujeres de población abierta que acuden al Hospital General de Zona No. 29. Material y métodos: se realizó la identificación de C. trachomatis por pruebas de PCR a 200 muestras de exudado vaginal y se determinó su genotipo. Paralelamente, se realizó el diagnóstico microbiológico de rutina. Resultados: la prevalencia de C. trachomatis fue del 8.5% (17/200) con una concomitancia significativa de p = 0.006 con Gardnerella vaginalis (riesgo relativo de 2.871, IC95%: 1.574-5.236). Asimismo, se identificó C. trachomatis en cinco muestras como el único agente etiológico. Dieciséis cepas de C. trachomatis pertenecieron al genotipo F. Una cepa identificada de C. trachomatis presentó motivos genéticos similares a la variante mexicana reportada en 2019. Conclusiones: la prevalencia de C. trachomatis en la población estudiada nos indica la necesidad de implementar técnicas de diagnóstico para esta bacteria. El uso de la PCR permite realizar una determinación genotípica rápida, que explicaría el comportamiento epidemiológico de la C. trachomatis y representaría una mejora significativa de la calidad de vida de la paciente.


Background: Chlamydia trachomatis is the main cause of sexually transmitted bacterial infections worldwide. An estimated of 131 million cases occur each year. It is asymptomatic, but ascending infection in women can lead to pelvic inflammatory disease, ectopic pregnancy, and infertility. Objective: To determine the prevalence of C. trachomatis in open population women who attend the Hospital General de Zona No. 29. Material and methods: Identification of C. trachomatis was carried out by PCR testing of 200 vaginal exudate samples and its genotype was determined. In parallel, a routine microbiological diagnosis was carried out. Results: The prevalence of C. trachomatis was 8.5% (17/200) with a significant concomitance of p = 0.006 with Gardnerella vaginalis (relative risk of 2.871, 95%CI: 1.574- 5.236). Likewise, C. trachomatis was identified in 5 samples as the only etiological agent. Sixteen strains of C. trachomatis belong to genotype F. An identified strain of C. trachomatis presented genetic motifs similar to the Mexican variant repor- ted in 2019. Conclusions: The prevalence of C. trachomatis in the studied population indicates the need to implement diagnostic techniques for this bacterium. The use of PCR allows a rapid genotypic determination that would explain the epidemiological behavior of C. trachomatis and would represent a sig- nificant improvement in the quality of life of the patient.

Background and Objectives: Healthcare-Associated Infections (HAIs) are an important public health problem that impacts negatively on hospital costs and patient prognosis. Given the importance of the hospital environment in the development of HAIs, the objective was to evaluate the bacterial profile on surfaces and equipment of the Orthopedic Clinic of the Hospital Universitário do Vale do São Francisco. Methods: This is a cross-sectional, descriptive, quantitative study. Samples were collected in 13 wards, each ward with four beds and one was chosen at random, where surfaces and equipment were sampled using swabs soaked in saline and a 1cm2 filter paper mold to standardize the samples. After passing the swab, they were stored in a tube containing 5mL of BHI (Brain Heart Infusion) liquid medium. Then, samples were transported to the Clinical Analysis Laboratory/Microbiology Sector where the microbiological analyzes were performed. Results: In total, 257 bacteria were observed, of which 5.11% were possible causes of hospital infection and 79% coagulase-negative Staphylococcus. Antibiograms of these were performed and different resistance profiles were found. The bathroom doorknob, a high-touch surface, presented the greatest variety of species among the evaluated surfaces. Conclusion: Surfaces and equipment of the evaluated clinic present possible bacteria that cause hospital infection with different profiles of antimicrobial resistance, contributing to possible cross infections.(AU)

ABSTRACT

Yersinia enterocolitica is a bacterium with zoonotic potential and there are no previous records of this bacteria being isolated from aborted foals. This report aims to describe a case of sepsis due to Y. enterocolitica in a seven month old aborted equine. The fequinoetus was submitted to necropsy and samples of all the organs were collected for the histological exam. Samples of liver, lung, placenta, and stomach contents were collected for bacterial culture. Macroscopically, the liver was enlarged with yellowish heterogeneous color, heart with pale myocardial areas; lungs not collapsed, heavy and shiny, thickened umbilical cord covered with fibrin and pus. Histopathologically, there was moderate multifocal necrosuppurative myocarditis and thrombosis, moderate diffuse suppurative bronchopneumonia, mild multifocal fibrinonecrotic hepatitis, and moderate diffuse necrosuppurative omphalitis with intralesional bacterial myriads and thrombosis. Mild multifocal suppurative placentitis, nephritis, myositis, cystitis, and dermatitis were also observed, in addition to mild diffuse lymphoid rarefaction. The microbiological evaluation identified Y. enterocolitica in the liver, lung, and stomach fluid. This is the first report of sepsis due to Y. enterocolitica causing an abortion in a horse. This bacterium has zoonotic importance; therefore, it should be investigated in abortion in this species, serving as a differential diagnosis in reproductive disorders.(AU)


Yersinia enterocolitica é uma bactéria com potencial zoonótico, e não há informações desse agente como causa de abortamento em equinos. O objetivo deste relato é descrever um caso de sepse por Y. enterocolitica em um feto equino abortado aos sete meses. O feto foi submetido à necropsia, e amostras de todos os órgãos foram processadas para histopatologia. Para microbiologia, foram coletadas amostras de fígado, pulmão, placenta e conteúdo estomacal. Macroscopicamente, observou-se fígado aumentado com coloração amarelada heterogênea; coração com áreas pálidas no miocárdio; pulmões não colabados, pesados e brilhantes; e cordão umbilical espessado e recoberto por fibrina e pus. Na análise histopatológica, havia miocardite necrossupurativa multifocal moderada e trombose, broncopneumonia supurativa difusa moderada, hepatite fibrinonecrótica multifocal discreta e onfalite necrossupurativa difusa moderada com miríades bacterianas intralesionais e trombose. Observou-se também placentite, nefrite, miosite, cistite e dermatite supurativa multifocal discreta, além de rarefação linfoide difusa discreta. A avaliação microbiológica identificou Y. enterocolitica no fígado, no pulmão e no líquido estomacal. Este é o primeiro relato de sepse por Y. enterocolitica causando abortamento na espécie equina. Essa bactéria tem importância zoonótica, portanto deve ser investigada em casos de abortamento nessa espécie, servindo como diagnóstico diferencial em tal distúrbio reprodutivo.(AU)

ABSTRACT

Potato scab caused by different species of phytopathogenic Streptomyces is considered one of the main bacterial diseases of economic crop importance worldwide. Several studies are being carried out in order to control the disease, but until now, there is no efficient way to do this. Some management strategies have been investigated including application of chemical and biological products and utilization of resistant cultivars of potato but there are few reports about the impact of pH and irrigation regimes on the disease. The present study aimed to evaluate the effects of these last two factors on the incidence and severity of potato scab caused by S. scabiei, S. acidiscabies, Streptomyces sp., S. caviscabies and S. europaeiscabiei in assays at pH 4.0, 4.5, 5.0, 5.5, 6.5 and 7.5; and irrigation regimes of once a week, alternate days and daily in greenhouse conditions. The experimental design for the pH tests was randomized blocks arranged in a 5x2 factorial scheme, with 5 replications and 3x2 for the irrigation regimes with 5 replications. The pH tests showed significant differences between the treatments and pH 4,0 - 4,5 presented lower incidence and severity of the disease for the most species tested but no significant differences were observed between the irrigation regimes. The soil acidification is considered a classic strategy for management of the disease and the results obtained herein corroborated this hypothesis.

ABSTRACT

Resumen Introducción: actualmente los profesionales de la salud se enfrentan al manejo de las vías aéreas artificiales en grupos pediátricos, esto requiere de cuidados delicados y mucha atención para detectar, establecer y manejar situaciones apremiantes; por esta razón, existe un mayor riesgo de aparición de infecciones bacterianas traqueopulmonares. El objetivo del estudio fue analizar la caracterización de las infecciones en pacientes pediátricos portadores de cánula de traqueotomía en las diferentes publicaciones científicas. Materiales y métodos: se realizó una revisión sistemática mediante la búsqueda de la literatura existente entre los años 2015-2020 en las bases de datos Elsevier, PubMed, Google Académico y SciELO, teniendo en cuenta los criterios de inclusión artículos en idioma inglés, español y población de edad entre los 0-15 años con infección de cánula de traqueotomía en los años 2015-2020. Resultados: de 258 artículos distribuidos en las bases de datos, se seleccionaron 21 artículos que cumplían con los criterios de inclusión. Conclusiones: a pesar de que en la actualidad existan criterios clínicos, factores de riesgo y pruebas de laboratorio asociados a infecciones de la cánula postraqueotomía en pacientes pediátricos, se requiere mayor investigación para definir las guías clínicas de manejo en la toma de decisiones médicas. Asimismo, se consideró como limitación importante la cantidad de literatura existente con respecto al tema.


Abstract Introduction: Currently, health professionals face the management of artificial airways in pediatric groups, this requires delicate care and a lot of attention to detect, establish and manage pressing situations, which is why there is a greater risk of tracheo-pulmonary bacterial infections. The objective was to analyze the characterization of infections in pediatric patients with tracheostomy tubes in the different scientific publications. Method: A systematic review of the literature was carried out between the years 2015-2020 in Elsevier, PubMed, Google Academic and SciELO databases, taking into account the inclusion criteria of the population aged 0-15 years in the years 2015-2020. The amount of existing literature on the subject was considered an important limitation. Results: From 258 articles distributed in the databases, 21 articles were selected that met the inclusion criteria. Conclusions: Although there are currently clinical criteria, risk factors and laboratory tests associated with infections of the post-tracheotomy tube in pediatric patients, further research is required to define clinical guidelines for management in medical decision-making.

ABSTRACT

Resumen La cinética de la procalcitonina es útil para reducir la duración de la antibioticoterapia en pacientes críticos, pero no se analizó su rol en infecciones por gérmenes multirresistentes. Se realizó un estudio observacional retrospectivo, analizando las curvas de procalcitonina de pacientes con neumonías asociadas a ventilación mecánica (NAVM) y bacteriemias asociadas a catéter (BAC) con rescate bacteriano durante el período 1/11/16 a 1/7/19. Se estudiaron 16 pacientes con infección por gérmenes sensibles (10 BAC y 6 NAVM) y 10 por gérmenes multirresistentes (10 BAC y 10 NAVM). Los pacientes con BAC generadas por gérmenes multirresistentes presentaron valores de procalcitonina mayores que los pacientes con BAC por gérmenes sensibles: (39 ± 30 μg/l vs. 10.7 ± 11 μg/l, p = 0.02). Los pacientes con NAVM generada por gérmenes sensibles y multirresistentes presentaron valores de procalcitonina similares. El descenso de procalcitonina a niveles 80% menores al valor máximo o menores a 0.5 μg/l (con tratamiento antibiótico efectivo) fue más veloz en pacientes con infección por gérmenes sensibles (5 ± 1.8 días vs. 7.2 ± 2.9 días, p = 0.03). En las infecciones por gérmenes multirresistentes, la respuesta inflamatoria medida por procalcitonina fue más intensa y prolongada, aun con un tratamiento antibiótico efectivo. Sin embargo, el descenso se produjo antes de que finalizaran los esquemas antibióticos convencionales. Por este motivo, se considera necesario estudiar la potencial utilidad de protocolos antibióticos guiados por procalcitonina en pacientes con infecciones por gérmenes multirresistentes para reducir la exposición a antibióticos.


Abstract Procalcitonin guidance stimulates a reduction in the duration of antibiotic treatment in critically ill patients with a presumed bacterial infection, but its role in infections caused by multidrug-resistant bacteria has not been sufficiently explored. In this retrospective observational study, we analyzed procalcitonin curves of 32 patients with culture-confirmed ventilation-associated pneumonia (VAP) and catheter-related bloodstream infections (CRBSI) occurred during the period 11/1/2016 to 7/1/2019. Sixteen infections were caused by multidrug-resistant bacteria (10 CRBSI and 6 VAP) and other 16 by sensitive bacteria (10 CRBSI and 6 VAP). CRBSI generated by multidrug-resistant bacteria elicited significantly higher procalcitonin levels than CRBSI infections caused by sensitive bacteria (39 ± 30 μg/l vs. 10.7 ± 11 μg/l, p = 0.02). Patients with VAP caused by sensitive and multidrug-resistant bacteria elicited similar procalcitonin levels. The time to a decrease in procalcitonin level to less than 80% of the peak value or less than 0.5 μg/l upon effective antibiotic treatment was 7.2 ± 2.9 days in multidrug-resistant bacteria vs. 5 ± 1.8 days in sensitive bacteria (p = 0.03). In multidrug-resistant bacteria, the inflammatory response measured by procalcitonin is stronger and longer, even with an effective antibiotic treatment. However, the decline occurs before the conventional antibiotic scheme is completed. The potential application of antibiotic protocols guided by procalcitonin to these groups of patients grants further studies aimed to reduce exposure to antibiotics in critical multidrug-resistant infections.

ABSTRACT

Introducción: El retraso en búsqueda de atención médica (RBAM) definido como un tiempo mayor a 48 horas antes de consultar un profesional podría influir en la severidad de las enfermedades en los niños. Métodos: En el presente estudio de cohorte prospectivo, se realizaron entrevistas estructuradas a tutores de niños que acudieron con fiebre a la emergencia del Hospital Baca Ortiz, verificando su estado de salud 5 días después, mediante una llamada telefónica. Las variables incluyeron demográficas, tiempo de atención y gravedad del cuadro. Se utilizó Chi cuadrado y Riesgo Relativo (RR) para buscar la relación entre dichas variables. Resultados: Fueron 304 pacientes ingresados al estudio, 41.1 % presentaron RBAM, cuyas principales causas fueron la administración de medicación sin receta médica en 48 % y la falta de detección de signos de alarma en 26.4 %. Los pacientes con RBAM presentaron más riesgo de requerir hospitalización (RR 1.88 IC 95 % 1.53-2.13 ), cuidados intensivos (RR 2.86 IC 95 % 1.00 8.17), presentar una infección bacteriana severa (RR 2.36 IC 95% 1.81 3.07), síndrome de respuesta inflamatoria sistémica (RR 2.47 IC 95 % 1.80 3.38), hospitalización al quinto día posterior a su valoración (RR 2.63 IC 95 % 1.94 3.57) y de mantenerse hospitalizado por más de 5 días (RR 1.46 IC 95 % 1.15 1.85). Conclusiones: El RBAM influye significativamente en la gravedad de los niños con fiebre, siendo la administración de medicación sin prescripción médica su principal causa


Introduction: Health careseeking delay, defined as a going to the doctor after more than 48 hours of starting fever, could influence in the severity of the disease. Methods: This prospective cohort study recollected the information with a questionnaire who examined demographic and health features of children younger than 15 years and older of 60 days that went with fever to the emergency room of Baca Ortiz´s Hospital, verifying their health condition five days after the initial evaluation through a phone call. Bivariate analysis was made with Chi-square and T student in order to relay these features with health care seeking delay and severity. Relative risk (RR), was used to measure the association between health care seeking delay and its consequent severity. Results: Of the 304 patients included in the study, 41.1 % had delay in seeking health care attention. The main causes for this delay were medicine administration without medical prescription in 48 % and lack of skills in recognizing alarm signs in 25.6 %. The patients who went to the hospital with delay had more risk of requiring hospitalization, (RR 1.88 CI 95 % 1.53- 2.13 ), intensive care cares (RR 2.86 CI 95 % 1.00 8.17), having a serious bacterial infection (RR 2.36 CI 95 % 1.81 3.07), having SIRS (RR 2.47 CI 95% 1.80 3.38), being hospitalized 5 days before their initial evaluation in emergency room (RR 2.63 CI 95 % 1.94 3.57) and staying at the hospital for more than five days (RR 1.46 CI 95 % 1.15 1.85). Conclusions: Health care seeking delay has an impact in the severity of the disease of children with fever. Administration of drugs without medical prescription is the principal reason. Health public politics should be achieved in order to educate population in these aspects to reduce morbimortality of children

ABSTRACT

Introducción: Las enfermedades bacterianas representan una de las causas más importantes de morbilidad y mortalidad en los pacientes infectados con el virus de la inmunodeficiencia humana (VIH). Ha este suceso se adicionan hoy las infecciones asociadas a los servicios sanitarios, escenario agravado por la aparición de bacterias con multirresistencia, las que impactan negativamente sobre la salud humana. Objetivo: Caracterizar las infecciones bacterianas en pacientes cubanos con el VIH, ingresados en el centro hospitalario del Instituto de Medicina Tropical Pedro Kourí, entre enero de 2014 y diciembre del 2017. Métodos: Se realizó un estudio de corte transversal con componente analítico cuyo universo estuvo constituido por 538 pacientes seropositivos en VIH-1 con diagnóstico de infección bacteriana documentada por aislamiento microbiológico. Resultados: Las infecciones bacterianas a nivel de vías respiratorias en pacientes con VIH y CD4 ≤ 200 cel/mm3 resultaron los eventos más frecuentes. Se demostró la mayor positividad en muestras de hemocultivo y esputos bacteriológicos 40,1 por ciento y 36,1 por ciento respectivamente. El 69,7por ciento de los aislamientos evidenciaron infección asociada a la asistencia sanitaria revelando asociación estadísticamente significativa con factores de riesgo seleccionados (estadías hospitalarias prolongadas y uso de dispositivos), además con la presencia de infección por bacterias gramnegativas y estafilococos coagulasa positivo. Conclusiones: Las infecciones bacterianas son frecuentes en pacientes VIH con inmunodepresión severa y su causa principal son las neumonías. Existe alta incidencia de infección asociada a la asistencia sanitaria, las que muestran asociación estadísticamente significativa con las estadías hospitalarias prolongadas y el uso de dispositivos, también revelan asociación con aislamientos de bacterias gramnegativas y estafilococos coagulasa positivo(AU)


Introduction: Bacterial diseases are one of the most important causes of morbidity and mortality in patients infected with human immunodeficiency virus (HIV). To this event are added nowadays infections associated with health services, a scenario aggravated by the emergence of bacteria with multi-resistance, which negatively impact human health. Objective: Characterize bacterial infections in Cuban HIV patients, admitted to the hospital center of Pedro Kourí Institute of Tropical Medicine between January 2014 and December 2017. Methods: A cross-sectional study with analytical component was conducted consisting of 538 HIV-1 positive patients diagnosed with bacterial infection detected by microbiological isolation. Results: Bacterial infections at the airway level in patients with HIV and CD4≤ 200cel/mm3 were the most common events. The highest positivity was demonstrated in samples of blood culture and bacteriological sputus with 40.1 percent and 36.1 percent, respectively. 69.7 percent of isolations showed healthcare-associated infection revealing statistically significant association with selected risk factors (prolonged hospital stays and devices use), as well as infection with gram-negative bacteria and coagulase-positive staph. Conclusions: Bacterial infections are common in HIV patients with severe immunosuppression and pneumonia is its main cause. There is a high incidence of healthcare-associated infection, which shows statistically significant association with prolonged hospital stays and devices use, also reveal association with isolations of gram-negative bacteria and coagulase-positive staph(AU)

ABSTRACT

Caseous lesions in the esophagus of green turtles (Chelonia mydas) from the coast of Brazil have been described as obstructive lesions and can lead to the death of these animals. However, their etiology remains unclear. The aim of this study was to isolate and characterize the aerobic bacterial microbiota of the esophagus of green turtles (C. mydas) from the Brazilian coast and to verify its possible participation in the etiology of caseous lesions. For this, 42 animals were used, 33 alive and healthy and 9 naturally dead that had esophageal lesions confirmed by necropsy, from Anchieta and Piúma beaches, Espírito Santo. Microbiological tests and morphological evaluation of the esophagus were performed. We isolated 14 different bacterial agents from healthy animal samples, with the prevalence of Pseudomonas aeruginosa being (36.36%), Staphylococcus aureus (33.33%), Aeromonas hydrophila (27.27%), and Vibrio alginolyticus (24.24%). In dead animals, only three distinct agents were isolated: S. aureus (50.00%), A. hydrophila (25.00%), and V. alginolyticus (25.00%). Morphological evaluation revealed a predominance of the lesions at the gastroesophageal junction, with multifocal-to-coalescent distribution, discrete intensity, and absence of obstruction. Ulcerations and caseous exudates, inflammatory infiltrates, parasitic eggs, and giant foreign body cells were also observed as well as bacterial lumps and glandular alterations, such as necrosis, adenitis, and fragments of adult parasites. There was a positive correlation between bacterial lumps and microbiological culture and a negative correlation between bacterial lumps and microbiological culture with parasites. Thus, it was noted that the esophageal aerobic microbiota of C. mydas was predominantly composed of Gram-negative bacteria such as P. aeruginosa, A. hydrophila, and V. alginolyticus, in addition to several enterobacteria and Gram-positive bacteria, such as S. aureus. These agents are opportunists and may be involved in the etiology of caseous esophagitis in association with other pathogens as co-factors working in association or, even in a secondary way.(AU)


A ocorrência de lesão caseosa no esôfago de tartarugas-verdes (Chelonia mydas) da costa do Brasil tem sido descrita como de caráter obstrutivo e pode causar a morte dos animais. No entanto, sua etiologia permanece pouco esclarecida. Objetivou-se isolar e caracterizar a microbiota aeróbica esofágica das tartarugas-verdes (C. mydas) da costa brasileira e verificar sua possível participação na etiologia das lesões caseosas. Foram utilizados 42 animais, 33 vivos e hígidos e nove mortos naturalmente que apresentavam lesão esofágica confirmada pela necropsia, provenientes de Anchieta e Piúma, Espírito Santo, nos quais foram feitos testes microbiológicos e avaliação morfológica do esôfago. Foram isolados 14 agentes bacterianos diferentes nas amostras de animais saudáveis, com prevalência de Pseudomonas aeruginosa (36,36%), Staphylococcus aureus (33,33%), Aeromonas hydrophila (27,27%) e Vibrio alginolyticus (24,24%). Nos animais mortos, foram isolados apenas três agentes distintos: S. aureus (50,00%), A. hydrophila (25,00%) e V. alginolyticus (25,00%). A avaliação morfológica revelou predominância da lesão em junção gastroesofágica, com distribuição multifocal a coalescente, intensidade discreta e ausência de obstrução. Observou-se ainda ulceração e exsudato caseoso, infiltrado inflamatório, ovos de parasitos e células gigantes do tipo corpo estranho, além de grumos bacterianos e de alterações glandulares, como necrose, adenite e fragmentos de parasitos adultos. Houve correlação positiva dos grumos bacterianos com cultivo microbiológico e negativa dos grumos bacterianos e cultivo microbiológico com parasitos. Assim, nota-se que a microbiota esofágica aeróbica de C. mydas é constituída predominantemente por bactérias Gram-negativas como P. aeruginosa, A. hydrophila e V. alginolyticus, além de diversas enterobatérias e por Gram-positivas, como S. aureus. Esses agentes são oportunistas e podem estar envolvidos na etiologia da esofagite caseosa em associação a outros patógenos como co-fatores agindo em associação, ou mesmo, por via de infecção secundária.(AU)

ABSTRACT

Resumen El género Gemella spp corresponde a cocos gram positivos, anaerobios facultativos, catalasa negativos, no móviles y no formadores de esporas, usualmente comensales de la cavidad oral, que no suelen ser patógenos en pacientes inmunocompetentes. Sin embargo, puede comportarse como germen oportunista en pacientes inmunosuprimidos o con otros factores de riesgo como mala higiene dental, cirugía gastrointestinal, enfermedades metabólicas entre otras, y se asocia con endocarditis, meningitis y en menor medida compromiso pulmonar. La información respecto a la susceptibilidad antimicrobiana es limitada y se asemeja a la de S viridans, por lo que la penicilina y ampicilina son los medicamentos de elección, sin tener claridad en cuanto a duración del tratamiento, usualmente considerando llevar a 4 semanas o hasta el drenaje de la colección. Éste reporte de caso describe una paciente con tuberculosis en tratamiento, que desarrolla una infección invasiva con documentación de empiema y bacteriemia secundaria por Gemella morbillorum, representando la asociación poco común de ésta infección bacteriana con tuberculosis.


Abstract Gemella spp. corresponds to gram positive cocci, facultative anaerobes, negative catalase, non mobile and non spore producers, part of colonizing flora of the oral cavity that are not common pathogens in immunocompetent patients. Nevertheless it may behave as an opportunistic germ in immunosuppressed patients or with other risk factors that include bad dental hygiene, bowel surgery, and metabolic diseases among others. It's associated with infections such as endocarditis, meningitis and less frecuently can implicate the lung. The information regarding antimicrobial susceptibility is limited and resembles S viridans, so penicillin and ampicillin are the medications of choice, without being clear about the duration of treatment, usually giving 4 weeks or until collection drain. This case report describes a patient with known tuberculosis diagnosis and under treatment, that develops an invasive infection with empyema and secondary bloodstream infection by Gemella morbillorum, depicting a previously uncommon but described association of this bacterial infection with tuberculosis.

ABSTRACT

Resumen Objetivo: La linfopenia se ha propuesto como un potencial factor asociado al riesgo de infecciones bacterianas nosocomiales (infección urinaria y neumonía), pero la magnitud y relevancia de este factor no ha sido evaluada formalmente. El objetivo de este estudio es determinar si existe asociación entre linfopenia e infecciones nosocomiales en ancianos hospitalizados en una institución de salud en Bogotá, Colombia. Métodos: Estudio de casos y controles, incluyendo personas mayores de 65 años hospitalizadas en el Hospital Universitario San Ignacio entre junio de 2016 y diciembre de 2017. Se consideraron casos aquellos con diagnóstico de infección nosocomial (neumonía, infección de vías urinarias, bacteriemia, infección de tejidos blandos) y se compararon con controles sin infección emparejados por edad y sexo. Se evaluó la asociación entre linfopenia e infección nosocomial mediante análisis bivariado y multivariado controlando por las variables de confusión. Resultados: Se incluyeron un total de 198 pacientes (99 casos y 99 controles). La prevalencia de linfopenia fue de 34.8%, sin encontrarse diferencia entre los dos grupos (p=0.88). La infección nosocomial se asoció a mayor incidencia de mortalidad (29.3 vs 10.1%, p>0.001) y mayor duración de estancia hospitalaria (Mediana 18 vs 9 días, p<0.01). Se encontró asociación entre infección nosocomial con enfermedad cardiovascular (OR = 2.87; IC 95% 1.37-6.00) y antecedente de cáncer (OR = 6.00; IC 95% 1.28-29.78), sin embargo, no hubo asociación con linfopenia (OR = 1.27; IC 95% 0.61-2.65). Conclusiones: Este estudio sugiere que no existe asociación entre linfopenia y el desarrollo de infecciones nosocomiales en pacientes ancianos.


Abstract Objective: Lymphopenia has been proposed as a potential factor associated with the risk of nosocomial bacterial infections (urinary tract infection and pneumonia), but the magnitude and relevance of this factor has not been formally evaluated. Objective is to determine the association between lymphopenia and nosocomial infections in elderly hospitalized in a health institution in Bogotá, Colombia. Methods: Case-control study, including people over 65 hospitalized in the University Hospital San Ignacio - Bogotá, during the period between June 2016 and December 2017. Cases with a diagnosis of nosocomial infection (pneumonia, urinary tract infection, bacteraemia, soft tissue infection) were considered and compared with controls without infection matched by age and sex. The association between lymphopenia and nosocomial infection was evaluated by bivariate and multivariate analysis, controlling for confounding variables. Results: A total of 198 patients (99 cases and 99 controls) were included. The prevalence of lymphopenia was 34.8%, with no difference between the two groups (p = 0.88). Nosocomial infection was associated with a higher incidence of mortality (29.3 vs. 10.1%, p> 0.001) and a longer duration of hospital stay (Median 18 vs. 9 days, p< 0.001). An association was found between nosocomial infection with cardiovascular disease (OR = 2.87; 95% CI 1.37-6.00) and a history of cancer (OR = 6.19; 95% CI 1.28-29.78), however, there was no association with lymphopenia (OR = 1.27 ; 95% CI 0.61-2.65). Conclusions: This study suggests that there is no association between lymphopenia and the development of nosocomial infections in elderly patients.

ABSTRACT

Resumen Introducción: Candida spp. Es la principal causa de fungemia, cuya incidencia ha aumentado en los últimos años. Existen datos locales insuficientes sobre este tipo de infecciones. Materiales y métodos: Este fue un estudio observacional retrospectivo de 44 pacientes diagnosticados con candidiasis invasiva hospitalizados en la Fundación Valle del Lili, el cual es un centro de cuarto nivel afiliado a la Universidad Icesi en el Suroccidente Colombiano, entre los años 2012 a 2017. Resultados: Se identificaron 44 pacientes con candidiasis invasiva, 27 de ellos mujeres (61%). La mediana de edad fue de 56 años (36 - 70). Más del 50% tenían una enfermedad crónica subyacente, uso de antibióticos (84%), catéter venoso central (80%), ventilación mecánica (68%) y nutrición enteral (66%) El 80% requirió manejo en unidad de cuidados intensivos (UCI) donde debutaron con sepsis (68%) y falla respiratoria (61%). En el 90% de los casos se aisló alguna especie de Candida spp. A partir de hemocultivo y sólo al 22% se le realizó prueba de sensibilidad. El tratamiento de elección fue con fluconazol (80%), asociado a caspofungina (70%). La tasa de mortalidad fue del 49%, con una mediana de 33 (22-49,5) días desde el ingreso hasta el fallecimiento. C. albicans fue el principal microorganismo aislado. La resistencia a azoles en especies no albicans existe en nuestro medio. Conclusión: La candidiasis se presenta como candidemia asociada a infección bacteriana concomitante, que cobra mayor importancia en el contexto del paciente inmunosuprimido asociado a elevadas tasas de mortalidad.


Abstract Introduction: Candida spp. is the main cause of fungemia, whose incidence has increased in recent years. There are insufficient local data about this pathology. Materials and methods: This was an observational, retrospective chart review of 44 patients diagnosed with invasive candida who were hospitalized at Fundación Valle del Lili, which is a fourth level center affiliated to Icesi university between 2012 and 2017. Results: We identified 44 patients with invasive candidiasis, 27 of them women (61%). The median age was 56 years (36 - 70). More than 50% had an underlying chronic disease, use of antibiotics (84%), central venous catheter (80%), mechanical ventilation (68%) and enteral nutrition (66%). 80% required management in an intensive care unit. Sepsis (68%) and respiratory failure (61%) were the most common clinical presentation. Almost 90% of the cases, had positive blood cultures, but only 22% presented susceptibility tests. The treatment was mainly fluconazole (80%), associated with caspofungin (70%). The mortality rate was 49%, median of 33 (22-49.5) days from admission to death. Candida albicans was the main isolated organism. Azole resistance in non-albicans species was observed. Conclusion: Candidiasis presents as bacterial infection associated candidemia, which becomes more important in the context of the immunosuppressed patient with high mortality rates.

ABSTRACT

Abstract The incidence of nontuberculous mycobacterial infections is increasing worldwide; by 2017, more than 190 species and subspecies have been documented. Although classically associated with immunosuppression, the recognition of these etiological agents in diseases affecting immunocompetent individuals and in healthcare-associated infections, such as after surgical and cosmetic procedures, makes the study of the epidemiology and pathogenesis of these microorganisms relevant in medical practice. Mycobacterium lentiflavum is slow-growing and rarely affects the skin. A case of cutaneous mycobacteriosis caused by M. lentiflavum is reported in an immunocompetent patient after subcutaneous injection of a lipolytic compound, treated with clarithromycin and levofloxacin.
