RESUMO

Las bacterias son capaces de desarrollar mecanismos de resistencia a los antimicrobianos, aquellos adquiridos y transmisibles son los más significativos debido al potencial de diseminación. La aparición de Salmonella enterica con resistencia a C3aG, quinolonas y a colistina representa una amenaza progresiva. El objetivo fue determinar la resistencia a los antimicrobianos y la presencia de los mecanismos de resistencia plasmídicos a quinolonas, ß-lactámicos y colistina en aislados de Salmonella provenientes de la vigilancia integrada de enteropatógenos. Fueron estudiadas 501 cepas de Salmonella spp. colectadas entre los años 2020 y 2021, por la red de enteropatógenos del Laboratorio Central de Salud Pública. Se investigó la resistencia a las C3aG, quinolonas y colistina, en aislamientos de humanos, alimentos, animales de consumo y ambiente. Las cepas estudiadas exhibieron resistencia a tetraciclina (32,5%), ácido nalidíxico (29%), ampicilina (13,2%), nitrofurantoína (11,6%), C3aG (7,2%), cotrimoxazol (5,8%), ciprofloxacina (2,2%). El 18% (90/501) presentaron resistencia trasferible por plásmidos, fueron detectados 111 genes (71 cepas con un gen, 17 cepas dos genes y 2 cepas tres genes diferentes). Qnr B: 41,1% (37/90), mcr-1: 38,9% (35/90), CMY: 23,3% (21/90), CTX-M: 16,7% (15/90) y Qnr S: 3,3% (3/90). Heidelberg fue el serovar predominante en muestras de pollo y el mayor portador de genes de resistencia de tipo CMY y mcr-1. La detección de genes en alimentos y animales de consumo, que pueden transmitirse fácilmente al ser humano es motivo de alerta y resalta la importancia de continuar fortaleciendo la vigilancia multisectorial y multidisciplinaria.


Bacteria can develop antimicrobial resistance mechanisms, those acquired and transmissible being the most significant due to the potential for dissemination. The emergence of Salmonella enterica with resistance to third-generation cephalosporins, quinolones, and colistin represents a progressive threat. The objective was to determine antimicrobial resistance and the presence of plasmid resistance mechanisms to quinolones, ß-lactams, and colistin in Salmonella isolates from integrated surveillance of enteropathogens. Five hundred and one strains of Salmonella spp. collected between 2020 and 2021 were studied by the enteropathogen network of the Laboratorio Central de Salud Publica (Central Public Health Laboratory). Research was conducted on the resistance to third-generation cephalosporins, quinolones, and colistin, isolated from humans, foodstuffs, animals for consumption, and the environment. The strains studied exhibited resistance to tetracycline (32.5%), nalidixic acid (29%), ampicillin (13.2%), nitrofurantoin (11.6%), third-generation cephalosporins (7.2%), cotrimoxazole (5.8%), and ciprofloxacin (2.2%). Eighteen percent (90/501) presented plasmid-transferable resistance, 111 genes were detected (71 strains with one gene, 17 strains with two genes, and 2 strains with three different genes). Qnr B: 41.1% (37/90), mcr-1: 38.9% (35/90), CMY: 23.3% (21/90), CTX-M: 16.7% (15/90), and Qnr S: 3.3% (3/90). Heidelberg was the predominant serovar in chicken samples and the largest carrier of CMY and mcr-1 resistance genes. The detection of genes in foodstuffs and animals for consumption, which can be easily transmitted to humans, is a cause for alarm and highlights the importance of continuing to strengthen multisectoral and multidisciplinary surveillance.

RESUMO

This work presents a portable framework to estimate potential park demand and park exposure through bipartite weighted networks. We use mobility information and open spatial information. Mobility information comes in the form of daily activities sampled from a model based on Call Detail Records (CDR). Spatial information comprise parks represented through OpenStreetMaps polygons and census tracts from the 2010 decennial US Census. The framework summarizes each city's information into one bipartite weighted network with the link weights representing the number of potential visits to a park from each census tract on an average weekday. We compare park exposure and park demand in Greater Los Angeles and Greater Boston in a pre-pandemic scenario. The park exposure of a census tract is calculated as the number of parks surrounding the daily activities of its inhabitants. The demand of a park is calculated as the number of daily activities surrounding it. We find that both cities' distribution of park exposure have similar shape with Boston having a higher average. On the other hand, the distribution of park demand is very similar in both cities, although their park spatial distributions are different. We include racial/ethnic information from the Census to explore how the park exposure connects tracts of different racial/ethnic groups. We associate parks to racial/ethnic groups based on the number of visitors from each group. Parks within minorities' tracts are mostly used by majority groups. Finally, through detecting communities in the network, we find that park exposure connects the cities locally, linking parks to their tracts nearby. Furthermore, we find a significant spatial correlation between network communities and different racial/ethnic composition in Los Angeles. This way, patterns of park exposure reproduce the separation among demographic groups of the city.

RESUMO

Atopic dermatitis predisposes to skin infections, and on the other hand, some therapies used for atopic dermatitis may worsen viral infections whose lesions may be more diffuse and resistant to treatment. The authors present a patient with severe atopic dermatitis and disseminated molluscum contagiosum infection. The molluscum contagiosum did not clear with topical treatment, and it worsened her atopic dermatitis even more, so the authors started treatment with dupilumab. After two months, the patient's dermatitis went into clinical remission and there was resolution of the infection with no recurrence at the 12-month follow-up. Dupilumab is nowadays a promising treatment for severe atopic dermatitis. To our knowledge, only four reports of molluscum contagiosum during dupilumab therapy have been reported in the literature, with contrasting effects. According to the authors' experience, treatment with dupilumab appears to be a safe alternative for patients with severe atopic dermatitis who are also infected with molluscum contagiosum, as opposed to other treatments such as systemic corticosteroids or cyclosporine.

RESUMO

La resistencia a los antimicrobianos (RAM), representa un grave problema por el uso indiscriminado de antimicrobianos de amplio espectro. En nuestro país, durante el primer cuatrimestre del año, se observó un aumento inusual en el número de aislamiento de gérmenes multirresistentes, sobre todo de bacilos gramnegativos, los cuales fueron remitidos al laboratorio de referencia con el objetivo de caracterizar los genes de resistencia a los carbapenemes. Estudio observacional y prospectivo de corte transversal en 456 aislamientos de bacilos gramnegativos provenientes de 11 centros colaboradores de la Red Nacional de Vigilancia de la RAM, remitidos al Laboratorio Central de Salud Pública entre enero y abril de 2021, para la detección molecular (reacción en cadena de la polimerasa múltiple) de los genes de resistencia enzimática bla OXA-51, bla OXA-23, bla OXA-24, bla OXA-48, bla OXA-58, bla NDM, bla KPC, bla IMP, bla VIM. Trescientos sesenta correspondieron a bacilos gramnegativos no fermentadores: 346 Acinetobacter baumannii y 14 Pseudomonas aeruginosa; 96 fueron miembros de Enterobacterales, siendo prevalente Klebsiella pneumoniae (81). Todos los aislamientos de Acinetobacter baumannii resultaron ser productores de carbapenemasas: OXA-23 (94%), NDM (4%), NMD+OXA-58 (2%); en Pseudomonas aeruginosa, 7 de los 14 aislamientos (50%) fueron portadores de metalobetalactamasa del genotipo NDM (100%). Los genotipos NDM (92%) y KPC (8%) fueron confirmados en Enterobacterales. La resistencia plasmídica a carbapenemes es endémica en nuestro país, siendo prevalentes los genotipos OXA-23 en Acinetobacter baumannii y NDM en Pseudomonas aeruginosa y Enterobacterales


Antimicrobial resistance (AMR) represents a serious problem due to the indiscriminate use of broad-spectrum antimicrobials. During the first quarter of the year, an unusual increase in the number of isolation multi-resistant germs, especially gram-negative bacilli was observed, specially of Gram-negative bacilli which were referred to the reference laboratory in order to characterize the carbapenems resistance genes. Observational and prospective cross-sectional study in 456 isolates of Gram-negative bacilli from 11 collaborating centers of the National AMR Surveillance Network, referred to the Central Public Health Laboratory (LCSP) between January and April 2021, for molecular detection (multiple polymerase chain reaction) targeting the enzymatic resistance genes: bla OXA-51, bla OXA-23, bla OXA-24, bla OXA-48, bla OXA-58, bla NDM, bla KPC, bla IMP, bla VIM. Of the 456 isolates studied, 360 corresponded to non-fermenting Gram-negative bacilli, of which 346 were confirmed as Acinetobacter baumannii and 14 Pseudomonas aeruginosa; 96 were Enterobacterales, being Klebsiella pneumoniae (81) the most prevalent. All isolates of Acinetobacter baumannii carried genes encoding carbapenemases, being the OXA-23 (94%) followed by NDM (4%) and NDM +OXA-58 (2%). In Pseudomonas aeruginosa strains, 7 of the 14 isolates (50%) were carriers of NDM metallobetalactamase (100%). No carbapenemase gene was detected in the remaining 7. In all Enterobacterales strains, the presence of carbapenemases of the NDM (92%) and KPC (8%) genotypes were confirmed. Plasmid resistance to carbapenems is endemic in our country, being the OXA-23 genotypes prevalent in Acinetobacter baumannii and NDM in Pseudomonas aeruginosa and Enterobacterales

RESUMO

BACKGROUND: Acute calculous cholecystitis (AC) is one of the most frequent surgical emergencies in our field. Laparoscopic cholecystectomy is considered the treatment of choice, although not sufficiently widespread. OBJECTIVE: To analyze the application of the Tokyo Guidelines in the management of AC and to determine the influence of the degree of severity on management and prognosis. METHOD: Prospective, observational study of patients with a primary diagnosis of AC between 2010 and 2015.. Exclusion criteria: AC recurrence; AC as a secondary diagnosis; acalculous cholecystitis; concurrent biliary pathology. Severity was classified according Tokyo 2013 Guidelines. RESULTS: 998 patients were included: 338 (33.9%) mild AC, 567 (56.8%) moderate AC, and 93 (9.3%) severe AC. A total of 582 (58.3%) patients were operated on. Postoperative complications Dindo-Clavien grade ≥ II 12.6%: mild AC 3.6%; moderate AC 12.2%; severe AC 49.0% (p < 0.001). Overall mortality 2%: mild AC 0%; moderate AC 0.5%; severe AC 18.0% (p < 0.001). CONCLUSION: Urgent laparoscopic cholecystectomy remains the treatment of choice for mild and moderate AC. In patients with severe AC, the risks and benefits of surgery should be assessed, given the high degree of complications and associated mortality.


ANTECEDENTES: La colecistitis aguda litiásica (CA) es una de las urgencias quirúrgicas más frecuentes en nuestro medio. La colecistectomía laparoscópica se considera el tratamiento de elección, aunque sigue sin ser una realidad su práctica generalizada. OBJETIVO: Analizar la aplicación de las Guías de Tokio en el manejo de la CA y determinar la influencia de la gravedad en el manejo y el pronóstico. MÉTODO: Estudio prospectivo, observacional, de pacientes con diagnóstico primario de CA entre 2010 y 2015. Criterios de exclusión: recidiva de CA, CA como diagnóstico secundario, CA alitiásica u otra patología biliar concomitante. Se ha clasificado la gravedad según las Guías de Tokio de 2013. RESULTADOS: Se incluyen 998 CA: 338 (33.9%) leves, 567 (56.8%) moderadas y 93 (9.3%) graves. Se operaron 582 pacientes (58.3%), y posteriormente 15 precisaron rescate. Complicaciones posoperatorias Dindo-Clavien ≥ 12,6%: CA leve 3,6%, CA moderada 12,2%, CA grave 49% (p < 0.001). Mortalidad global 2%: CA leve 0%, CA moderada 0.5%, CA grave 18% (p < 0.001). CONCLUSIÓN: La colecistectomía laparoscópica sigue siendo el tratamiento de elección para la CA leve y moderada. En pacientes con CA grave debe valorarse el riesgo-beneficio de la cirugía, dadas las complicaciones y la mortalidad asociadas.

RESUMO

El carácter colaborativo de un Sistema Nacional de Innovación presupone la implantación de políticas públicas para la innovación, que deben orientar la acción y la interacción de los agentes de dicho sistema. En este contexto, la universidad asume un papel relevante porque es la gran responsable de la producción del conocimiento científico en las naciones. El objetivo general de la investigación se orientó al análisis de políticas públicas nacionales e institucionales y a los indicadores de innovación de Brasil y España en lo que se refiere a la producción y al intercambio del conocimiento científico. Se optó por una investigación de naturaleza cualitativa, integrada por el análisis bibliográfico y documental, y un estudio comparativo entre políticas e indicadores de CT&I vigentes en los ámbitos brasileño y español. Se concluye que los documentos analizados enfocan los conceptos y principios de la interacción, pero se hace necesaria la incorporación de aspectos que contribuyan a la efectividad de la actuación integrada y el intercambio de conocimiento entre los agentes de los respectivos sistemas nacionales de innovación(AU)


The collaborative nature of national innovation systems implies the implementation of public policies for innovation, intended to guide the action and interaction of the agents involved in the system. Universities play a relevant role in that context, being as they are major producers of scientific knowledge in countries. The general purpose of the study was to analyze national and institutional public policies and innovation indicators from Brazil and Spain related to the production and exchange of scientific knowledge. A qualitative study was conducted consisting in bibliographic and document analysis and a comparison between ST&I indicators and policies in place in Brazil and Spain. The documents analyzed were found to address interaction concepts and principles, but it is necessary to include aspects contributing to the effectiveness of integrated action and exchange of knowledge between the agents involved in the national innovation systems(AU)

RESUMO

An increase in the severity of drought events on Mediterranean climates highlights the need of using plant material adapted to drought during restoration efforts. Thus, we investigated between-population morpho-physiological differences in Cryptocarya alba and Persea lingue, two native species from Mediterranean central Chile, for traits that could effectively discriminate population performance in response to water restriction (WR) testing. Three populations from each species were subjected to WR treatment and physiological, morphological, and growth parameters were assessed at the beginning and at the end of the experiment. In C. alba, the most xeric population displayed smaller plants with mesophyllous leaves and lower photosynthetic rates indicating a resource saving strategy. Moreover, the xeric population performed better during WR than the most mesic populations, exhibiting higher water use efficiency (iWUE) and maintenance of growth rates. All C. alba populations responded equally to WR in terms of morphology and biomass partitioning. In contrast, differences among P. lingue populations were subtle at the morpho-physiological level with no apparent relation to provenance environmental conditions, and no morphological traits were affected by WR. However, in response to WR application, the most mesic population was, as observed through reduction in relative growth rates, more affected than xeric populations. We attribute such discrete differences between P. lingue provenances to the lower distributional range of selected populations. Our results show that relative growth rates in both species, and iWUE only in C. alba, exhibited population specific responses upon WR imposition; these results correspond with the environmental conditions found at the origin of each populations. Both traits could further assist in the selection of populations for restoration according to their response to water stress.

RESUMO

Nowadays, 23% of the world population lives in multi-million cities. In these metropolises, criminal activity is much higher and violent than in either small cities or rural areas. Thus, understanding what factors influence urban crime in big cities is a pressing need. Seminal studies analyse crime records through historical panel data or analysis of historical patterns combined with ecological factor and exploratory mapping. More recently, machine learning methods have provided informed crime prediction over time. However, previous studies have focused on a single city at a time, considering only a limited number of factors (such as socio-economical characteristics) and often at large in a single city. Hence, our understanding of the factors influencing crime across cultures and cities is very limited. Here we propose a Bayesian model to explore how violent and property crimes are related not only to socio-economic factors but also to the built environmental (e.g. land use) and mobility characteristics of neighbourhoods. To that end, we analyse crime at small areas and integrate multiple open data sources with mobile phone traces to compare how the different factors correlate with crime in diverse cities, namely Boston, Bogotá, Los Angeles and Chicago. We find that the combined use of socio-economic conditions, mobility information and physical characteristics of the neighbourhood effectively explain the emergence of crime, and improve the performance of the traditional approaches. However, we show that the socio-ecological factors of neighbourhoods relate to crime very differently from one city to another. Thus there is clearly no "one fits all" model.

RESUMO

En diciembre de 2019 se reporta un brote de infección respiratoria aguda de etiología desconocida, en la ciudad de Wuhan, China, cuya causa se atribuyó poco después a un nuevo virus denominado SARS-CoV-2. En marzo de 2020 la enfermedad causada por este virus: COVID-19, fue declarada pandemia por la OMS. Como consecuencia, se recomendó restringir las intervenciones quirúrgicas, limitándolas a aquellas urgentes y las que no debían diferirse por comprometer la salud del paciente. Organismos internacionales y sociedades científicas han emitido recomendaciones para la asistencia sanitaria y la actividad quirúrgica. Se requeriría adecuarlas al contexto social y geográfico donde se desarrollará la actividad de salud en Cuba. Atendiendo a estas circunstancias se elaboraron recomendaciones adaptadas a las condiciones propias de las instituciones hospitalarias de perfil pediátrico más comunes de nuestro país, con el objetivo de contribuir a organizar la asistencia médico quirúrgica de urgencia a pacientes pediátricos positivos o sospechosos de tener COVID-19, cumpliendo las condiciones de seguridad para el paciente y el personal sanitario a su cargo(AU)


In December 2019, it was reported the outbreak of an acute respiratory infection of unknown etiology, in the city of Wuhan, China, whose cause was shortly after attributed to a new virus called SARS-CoV-2. In March 2020 the disease caused by this virus, COVID-19, was declared a pandemic by the WHO. As a consequence, it was recommended to restrict surgical interventions, limiting them to those that are priorities and the ones that should not be deferred since can be compromised the health of the patient. International agencies and scientific societies have issued recommendations for the health care and surgical activities. It is needed to suit them to the social and geographical context where the health activity is developed in Cuba. This is the reason to conform recommendations adapted to the conditions of pediatric medical institutions in our country, with the aim of contributing to organize the emergency surgical care to pediatric patients positive or suspected of having COVID-19, while accomplishing the safety requirements for the patient and the health personnel in charge(AU)

RESUMO

Nowadays, the retreatment of patients with Hepatitis C virus (HCV) genotype 3 (GT3) especially cirrhotic, who have already been treated with regimens containing a NS5A inhibitor represents a challenge. Use a novel retreatment option for patients with a difficult approach. We present three case reports of retreatment with a new combination of Direct-acting antivirals (DAAs), Sofosbuvir, Elbasvir/Grazoprevir in patients with GT3 with a previous failure with Sofosbuvir/Ledipasvir. All the cases achieved sustained virologic response (SVR) at week +12 without adverse effects. In our experience, this combo may represent an effective and safe option for these patients.

RESUMO

Stories of mega-jams that last tens of hours or even days appear not only in fiction but also in reality. In this context, it is important to characterize the collapse of the network, defined as the transition from a characteristic travel time to orders of magnitude longer for the same distance traveled. In this multicity study, we unravel this complex phenomenon under various conditions of demand and translate it to the travel time of the individual drivers. First, we start with the current conditions, showing that there is a characteristic time τ that takes a representative group of commuters to arrive at their destinations once their maximum density has been reached. While this time differs from city to city, it can be explained by Γ, defined as the ratio of the vehicle miles traveled to the total vehicle distance the road network can support per hour. Modifying Γ can improve τ and directly inform planning and infrastructure interventions. In this study we focus on measuring the vulnerability of the system by increasing the volume of cars in the network, keeping the road capacity and the empirical spatial dynamics from origins to destinations unchanged. We identify three states of urban traffic, separated by two distinctive transitions. The first one describes the appearance of the first bottlenecks and the second one the collapse of the system. This collapse is marked by a given number of commuters in each city and it is formally characterized by a nonequilibrium phase transition.

RESUMO

This paper presents a data analysis framework to uncover relationships between health conditions, age and sex for a large population of patients. We study a massive heterogeneous sample of 1.7 million patients in Brazil, containing 47 million of health records with detailed medical conditions for visits to medical facilities for a period of 17 months. The findings suggest that medical conditions can be grouped into clusters that share very distinctive densities in the ages of the patients. For each cluster, we further present the ICD-10 chapters within it. Finally, we relate the findings to comorbidity networks, uncovering the relation of the discovered clusters of age densities to comorbidity networks literature.

RESUMO

Se analizan presupuestos teóricos sobre la relación entre la sociedad y la universidad y la pertinencia de la inserción de temas que demandan su presencia en los planes de estudio y proyectos de investigación de estas instituciones. Se contextualiza el envejecimiento poblacional como una de las responsabilidades sociales de obligada introducción en los programas de estudio de la carrera de Medicina, lo cual posibilita ratificar el carácter científico, tecnológico y humanístico de la educación superior cubana al asumir en sus procesos sustantivos la formación de un profesional integral, competente, con preparación científica para aceptar los retos de la modernidad, y con amplio desarrollo humanístico para vivir en una sociedad con una población envejecida. Los autores se propusieron como objetivo reflexionar acerca de la pertinencia del tema en el currículo de la carrera, como expresión del vínculo universidad-sociedad.


Theoretical foundations about the relationship between university and society and the pertinence of the insertion of topics that demand their presence in the study plans and research projects of these institutions are analyzed. Population aging is contextualized as one of the social responsibilities of necessary introduction in the study programs of the Medicine career, which makes it possible to ratify the scientific, technological and humanistic character of Cuban higher education by assuming in its core processes the formation of a comprehensive professional, competent, with scientific preparation to accept the challenges of modernity, and with ample humanistic development to live in a society with an aging population. The authors set out to reflect on the relevance of the topic in the career curriculum as an expression of the university-society link.

RESUMO

Giardia duodenalis is considered the most common protozoan infecting humans worldwide. Molecular characterization of G. duodenalis isolates has revealed the existence of eight groups (assemblages A to H) which differ in their host distribution. A cross-sectional study was conducted in 639 children from La Habana between January and December 2013. Two assemblage-specific PCRs were carried out for the molecular characterization. The overall prevalence of Giardia infection was 11.9%. DNA from 63 of 76 (82.9%) samples was successfully amplified by PCR-tpi, while 58 from 76 (76.3%) were detected by PCRE1-HF. Similar results by both PCRs were obtained in 54 from 76 samples (71%). According to these analyses, assemblage B and mixed assemblages A + B account for most of the Giardia infections in the cohort of children tested. Our current study identified assemblage B as predominant genotype in children infected with Giardia. Univariate analysis indicated that omission of washing hands before eating and keeping dogs at home were significant risk factors for a Giardia infection. In the future, novel molecular tools for a better discrimination of assemblages at the subassemblages level are needed to verify possible correlations between Giardia genotypes and symptomatology of giardiasis.

RESUMO

El internacionalismo, como valor social, constituye uno de los rasgos esenciales que ha caracterizado a la salud pública cubana desde el triunfo de la Revolución. En noviembre de 2005 se inició la colaboración cubana en materia de salud a la atención de pacientes con insuficiencia renal crónica en Santa Lucía, enfermedad que constituye un importante problema de salud en ese país del Caribe. El objetivo de este artículo está dirigido a destacar el rol de la colaboración cubana en la asistencia al problema de la insuficiencia renal crónica en Santa Lucía, a partir de la realización de diversas intervenciones bien definidas, con énfasis en el impacto de dicha cooperación en la Unidad Renal del Hospital Victoria.


Internationalism, as a social value, is one of the essential characteristics of Cuban public health since the triumph of the Revolution. In November 2005, Cuban medical cooperation in the care of patients with chronic renal failure began in Saint Lucia. This disease constitutes a major health problem in the Caribbean nation. The aim of this article is to highlight the role of Cuban cooperation in assisting chronic renal failure patients in Santa Lucia through various well-defined interventions, emphasizing on the impact of such cooperation in the Renal Unit of the Victoria Hospital.

RESUMO

Epidemic trajectories and associated social responses vary widely between populations, with severe reactions sometimes observed. When confronted with fatal or novel pathogens, people exhibit a variety of behaviours from anxiety to hoarding of medical supplies, overwhelming medical infrastructure and rioting. We developed a coupled network approach to understanding and predicting social response. We couple the disease spread and panic spread processes and model them through local interactions between agents. The social contagion process depends on the prevalence of the disease, its perceived risk and a global media signal. We verify the model by analysing the spread of disease and social response during the 2009 H1N1 outbreak in Mexico City and 2003 severe acute respiratory syndrome and 2009 H1N1 outbreaks in Hong Kong, accurately predicting population-level behaviour. This kind of empirically validated model is critical to exploring strategies for public health intervention, increasing our ability to anticipate the response to infectious disease outbreaks.

RESUMO

OBJECTIVE: To report a case of co-infection with Neisseria gonorrhoeae and Actinomyces naeslundii in a woman with an intrauterine device. CASE REPORT: A 36-year-old woman with IUD, who entered to the hospital because of suprapubic abdominal pain, fever and foul-smelling vaginal discharge. RESULTS: We identified Neisseria gonorrhoeae and Actinomyces naeslundii and despite antibiotic treatment, ultrasound allowed objectify pelvic inflammatory disease and appendiceal involvement, which led to its surgical removal and bilateral salpingectomy. CONCLUSIONS: The surgical approach allowed to solve the box co.
