Microsporum canis pseudomycetoma and disseminated Mycobacterium genavense infection in an HIV/AIDS patient, an unusual combination.

Pseudomycetomas are rare fungal subcutaneous infections caused by dermatophytes, which are mainly observed in immunocompromised patients. Mycobacterium genavense is considered an opportunistic pathogen in people living with HIV/AIDS (PLWHA), clinically resembling the presentation of Mycobacterium avium complex (MAC). Here, we describe the case of a 26-year-old PLWHA with a 3-month history of a 4cm tumoral, duroelastic and painful lesion located on the back. Histopathology of the tumoral lesion revealed chronic granulomatous inflammation with grains composed of PAS-positive and Grocott-positive septate hyphae, as well as acid-fast bacilli (AFB). Culture on Sabouraud and lactrimel agar developed colonies that were later identified as Microsporum canis. In successive samples, the AFB were identified as M. genavense by restriction analysis of PCR products. Immunocompromised PLWHA not only suffer increased susceptibility to diseases due to unusual pathogens but also atypical clinical presentation of frequently encountered pathogens.

Risk factors and mortality of candidemia in a children's public hospital in Sao Paulo, Brazil.

Candida bloodstream infections in children are of special concern in neonatal and pediatric intensive care and patients with comorbidities. This study aimed to estimate the incidence and risk factors associated with mortality in candidemia cases occurring in a public children's hospital in Ribeirao Preto, Brazil. It is a retrospective transversal study. Every patient under the age of 18 admitted to the study facility from January 1, 2013, to December 31, 2019, was considered potentially eligible to be included if they had candidemia. We collected clinical data from medical records. We included 113 blood cultures yielding positive results for Candida. The incidence rate was 2.12 per 1000 admissions. The most common Candida species was Candida parapsilosis. Septic shock during the candidemia episode was the only clinical outcome associated with a relative risk-adjusted (RRa) of 2.77 with an interval >1 (1.12-6.85). Our findings show that the incidence rate and mortality rates of candidemia are in line with those in other children's services in Brazil. We found a global mortality rate of 28.31% (32/113) from candidemia episodes. We highlight the predominance of non-albicans Candida species including C. parapsilosis. Septic shock was the most important factor showing a significant risk of mortality.

Evaluation of health status of transgender sex workers in Turkey: A qualitative study.

OBJECTIVE: Sex workers can be disadvantaged in terms of overall health due to challenging living and working conditions. This research aimed to evaluate the health status and experiences related to sexually transmitted infections (STDs) of unregistered transgender sex workers in Turkey. DESIGN: It employed a phenomenological qualitative research design. SITE: Data were collected in Istanbul between March 2021 and November 2021. PARTICIPANTS: Data were collected through in-depth interviews involving 24 people (19 sex workers and 5 physicians). METHODS: Key statements were listed during data analysis, and clusters of meanings were formed based on these statements. The participants' statements were used for contextual and structural descriptions. RESULTS: Sex workers suffer from chronic illnesses such as asthma, chronic obstructive pulmonary disease (COPD), diabetes, allergic diseases, and neurological disorders. Among the health issues affecting them, the most notable ones are STDs, psychological problems, and the risk of suicide. Sex workers also face a dilemma between choosing public hospitals and private hospitals. Majority of sex workers undergo regular testing for STDs, with the frequency varying from person to person. Reasons for not undergoing regular testing include lack of social security coverage, financial constraints, lack of information, and feeling undervalued. Some individuals are being subjected to mandatory testing. CONCLUSIONS: It is recommended that sex workers who seek and request healthcare services should be provided with detailed information and education, particularly regarding psychological problems and STDs.

[Management of sexually transmitted diseases in primary care (II). Genital ulcers. Vulvovaginitis. Human papilloma virus]. / Manejo en atención primaria de las infecciones de transmisión sexual (II). Lesión ulcerada genital. Vulvovaginitis. Virus del papiloma humano.

In this paper we approach three clinical syndromes with different microbial agents that cause sexually transmitted diseases (STD) with a common condition: the symptomatology is in the genital area. Some of these microbial agents are transmitted strictly sexually, but not all. In this section we will discuss about vulvovaginitis, genital ulcers and human papilloma virus, three syndromes which have increased their incidence in recent years and primary care must know its management: diagnosis, correct treatment, controls, and study of sexual contacts. The optimal approach is as important as knowing how to recommend prevention of STD, contact study and screening for other infections that can be present at the same time although asymptomatically.

Development of a Questionnaire on Knowledge, Habits, and Attitudes on Sexually Transmitted Infections in Teenagers and Young Adults.

Communication with teenagers who are significantly affected by sexually transmitted infections (STIs) is essential for the sake of prevention. The aim of this study is to develop a specific questionnaire for surveying the degree of knowledge, behavior, and attitudes of current teenagers and young adults on STIs to come up with the proper training tools. We conducted the study following the Delphi method, a 2-round critical assessment score (from 1 to 9) of all domains and items. Only domains and items with median scores ≥8 were selected. A total of 8 panelists were involved in this survey. After establishing a median score ≥8, a total of 14 domains and 40 items were eventually selected. This is the first questionnaire ever conducted to study the knowledge, habits, and attitudes of contemporary teenagers and young adults on STIs, and stands as a valuable tool for future training on STI prevention in teenagers and young adults.

AEDV Expert Recommendations on the Management of Suppurative Sexually Transmitted Infections. / Recomendaciones de expertos de la AEDV sobre el manejo de infecciones venéreas supurativas.

The incidence of sexually transmitted infections (STIs) is increasing in Spain. Suppurative STIs are one of the most frequent reasons for consultation in specialized centers. The reason for suppurative STIs is multiple and their empirical treatment varies with the currently growing problem of antimicrobial resistance. Dermatologists are trained and prepared to treat these diseases, but their correct management requires active knowledge of national and international guidelines. The present document updates, reviews and summarizes the main expert recommendations on the management and treatment of these STIs.

AEDV Expert Document on the Management of Ulcerative Venereal Infections. / Documento de expertos de la AEDV sobre el manejo de infecciones venéreas ulcerativas.

Currently, ulcerative sexually transmitted infections, including syphilis, herpes simplex virus (HSV), lymphogranuloma venereum (LGV), chancroid, donovanosis and, more recently, monkeypox (MPOX), represent a growing challenge for health care professionals. The incidence of syphilis and LGV has increased in recent years in Spain. Additionally, HSV, syphilis and chancroid can also increase the risk of HIV acquisition and transmission. The population groups most vulnerable to these infections are young people, men who have sex with men (MSM) and commercial sex workers. It is important to make a timely differential diagnosis since genital, anal, perianal, and oral ulcerative lesions may pose differential diagnosis with other infectious and non-infectious conditions such as candidiasis vulvovaginitis, traumatic lesions, carcinoma, aphthous ulcers, Behçet's disease, fixed drug eruption, or psoriasis. For this reason, the dermatologist plays a crucial role in the diagnosis and management of sexually transmitted infections. This chapter presents the main epidemiological, clinical and therapeutic features associated with these infections.

AEDV Expert Consensus Document on the Organization of a Multidisciplinary Unit for Patients With or at Risk of Venereal Infections. / Documento de expertos de la Academia Española de Dermatología y Venereología sobre la organización de una unidad multidisciplinar de atención a pacientes con o en riesgo de infecciones venéreas.

Over the past few years, venereal or sexually transmitted infections (STIs) have been on the rise worldwide requiring additional specialized monographic consultations to specifically treat STIs. Therefore, the Spanish Academy of Dermatology and Venereology (AEDV) Research Working Group on STIs and HIV has drafted this document with the necessary requirements in terms of infrastructure, personnel, technology, specific materials for sample collection, and needs for current therapeutic options. Strict emphasis is placed on the protection of patient privacy. A health care circuit model is outlined too. Additionally, a section has been included on contact tracking and reporting, key elements for the effective prevention and control of STIs. These clinical practice guidelines seek to establish a clinical action framework adapted to the current challenges posed by STIs and HIV in the dermatology, venereology, and multidisciplinary settings.

Expert Recommendations from the AEDV on Legal Aspects Surrounding the Management of Sexually Transmitted Diseases. / Recomendaciones de expertos de la AEDV sobre los aspectos legales en el manejo de las infecciones de transmisión sexual.

The incidence of sexually transmitted diseases has been on the rise in our setting for decades. These infections represent not only an individual problem, but also a problem of public health. Therefore, the management of STDs involves reducing community incidence, which means that common issues in the clinical practice such as failure to attend may become a more complex problem, which adds to the difficult and delicate task of locating sexual contacts that would benefit from screening and the appropriate treatment. On the other hand, STDs have direct legal implications in cases of underage patients, or suspected sexual assault. Therefore, the correct handling of these scenarios requires knowledge of the legal framework that regulates them. Dermatologists are clinically trained and prepared to deal with these conditions. Nonetheless, the legal issues involved are often difficult to solve. This document stands as a simple reference guide to help solve the main legal issues we may encounter in a consultation when dealing with STDs.

In house-development of a rapid immunochromatographic test for the detection of Escherichia coli in urine samples.

Urinary tract infections (UTIs) are a common health concern. Urine culture is the "gold standard" for UTI diagnosis but takes 48h. Rapid methods like dipstick tests are used as point-of-care tests. However, their sensitivity and specificity are variable. In this work, a rapid immunochromatographic test (IT) for detecting Escherichia coli in urine was developed, and its performance was evaluated in urine samples from patients with suspected UTI. The "universal lateral flow assay kit" was employed using an E. coli capture antibody. One hundred and five (105) urine samples were analyzed using the IT, dipstick test, and urine culture. The sensitivity of the IT was 74.5%, specificity 88.9%, positive predictive value (PPV) 86.3%, and negative predictive value (NPV) 78.7%. The combination of the IT with the dipstick test increases sensitivity to 94.1%, specificity to 66.7%, PPV to 72.7%, and NPV to 92.3%. Using the IT for detecting E. coli in urine could be a valuable technique for UTI screening, showing better specificity and diagnostic precision but lower sensitivity than the dipstick test. Based on these results, we propose that the combined use of both screening techniques would allow a rapid and more precise diagnosis of UTI, rationalizing the indication for empirical antibiotics.

[Primary care management of sexually transmitted infections (I). Epidemiology. Secreting syndrome]. / Manejo en atención primaria de las infecciones de transmisión sexual (I). Epidemiología. Síndrome secretor.

These days sexually transmitted infections (STIs) are important public health problems not only due to their high prevalence, but also because they require early diagnosis and treatment to avoid complications. In recent years, there has been an exponential increase in cases of infections caused by Chlamydia trachomatis and gonococcus in the population under 25years of age. In addition, an increase in the incidence of syphilis and hepatitisC (HCV) has also been detected, especially in men who have sex with other men (MSM). Genital herpes continues to be the second most frequent STI in the world, behind condyloma acuminata, and the first cause of genital ulcer among Spain in the sexually active population. A decrease in reported HIV cases was observed during 2020, but almost half of these new cases had a late diagnosis (<350CD4cell/µL). Current guidelines recommend offering STI annual screening to populations at risk or more often depending on the risk. STIs can appear in the form of syndromes, such as secretory syndrome (urethritis, proctitis, and cervicitis) or ulcerated syndrome (ulcers). The STIs that can cause secretory syndrome are mainly caused by Neisseria gonorrhoeae and C.trachomatis, which co-infect up to 40% of cases, and also cause urethritis, cervicitis or proctitis depending on where they are located. Gonococcus has an incubation period of 2-7days and Chlamydia 2-6weeks, and they are diagnosed using PCR and/or culture (the last one only valid for gonococcus) of samples collected according to sexual activities. Empirical treatment to cover both germs will be accomplished with ceftriaxone, 1g single intramuscular dose plus doxycycline 100mg every 12h orally for 7days, or azithromycin 1g single dose orally (we will use azithromycin only if we suspect a poor compliance with treatment, difficulty in going to the control or in pregnancy). Likewise, whenever we diagnose an STI firstly, we must offer advice and health education in order to promote the adoption of safe sexual behaviours and the correct use of barrier methods. Secondly, we must also screen for other STIs (HIV, syphilis, hepatitisB, and hepatitisA andC depending on the risk), offer HBV and HAV vaccination if it is appropriate, and finally study and treat all sexual partners from the previous 3months.

New paradigms on antibiotic recommendations for community-acquired infections in Spain.

Over the last years, the susceptibility activity of the most common microorganisms causing community-acquired infections has significantly changed in Spain. Based on the susceptibility rates of Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Klebsiella pneumoniae collected from outpatients aged 15 or older with symptoms of respiratory or urinary tract infections in several Microbiology Departments in Catalonia in 2021, penicillin V should be first choice for most respiratory tract infections, amoxicillin and clavulanate for chronic obstructive pulmonary disease exacerbations and a single dose of fosfomycin or a short-course nitrofurantoin should remain first-line treatments for uncomplicated urinary tract infections. Updated information on antimicrobial resistance for general practitioners is crucial for achieving appropriate empirical management of the most common infections by promoting more rational antibiotic use.

Risk factors for healthcare-associated infections in newborns after surgery in a neonatal intensive care unit.

BACKGROUND: Health care-associated infections (HAIs) are a common cause of morbidity and mortality. There is little information on the risk factors associated with HAI in surgical newborns. OBJECTIVE: To identify the risk factors associated with healthcare-associated infections in surgical newborns. METHODS: Nested case-control study carried out during 2016-2017. Cases were newborns with healthcare-associated infections and controls were newborns without infection. Perinatal characteristics, use of antimicrobial prophylaxis, use of central venous catheter (CVC), mechanical ventilation, parenteral nutrition, age, and weight at the time of surgery, type of surgery, surgical wound classification, duration of surgery, number of surgical procedures, postsurgical HAIs and type of infection were registered. Univariate and multivariate analyses were performed. RESULTS: Seventy-one cases and 142 controls were included. The most frequent HAI was bloodstream infection (36.6%); the main microorganisms isolated in blood cultures were gram-positive cocci. Independent risk factors associated with HAIs in the multivariate analysis were CVC duration > 8 days (aOR = 17.2, 95% CI = 3.8-49.1), ≥ 2 surgeries (aOR = 16.5, 95% CI 5.8 -42.1) and abdominal surgery (aOR = 2.6, 95% CI = 1.2-6.6). CONCLUSION: Newborns undergoing surgery, mainly those with risk factors, require close monitoring during the postoperative period. CVC should be withdrawn as soon as possible.

ANTECEDENTES: Las infecciones asociadas a la atención de la salud (IAAS) son causa frecuente de morbilidad y mortalidad. OBJETIVO: Identificar los factores de riesgo para el desarrollo de IAAS en recién nacidos (RN) sometidos a cirugía. MATERIAL Y MÉTODOS: Estudio de casos y controles anidado en una cohorte. Los casos fueron RN sometidos a cirugía, con IAAS y los controles, RN sometidos a cirugía sin IAAS. Se registraron datos perinatales, uso de profilaxis antimicrobiana, de catéter venoso central (CVC), ventilación mecánica, nutrición parenteral y sondas; edad y peso al momento de la cirugía, tipo de cirugía, clasificación de la herida quirúrgica, duración de la cirugía, número de procedimientos quirúrgicos y tipo de infección. Se realizó análisis univariado y multivariado. RESULTADOS: Se incluyeron 71 casos y 142 controles. Las IAAS más frecuentes fueron las infecciones sanguíneas (36.6 %); los principales microorganismos aislados en hemocultivos fueron cocos grampositivos. Los factores de riesgo asociados a IAAS en el análisis multivariado fueron duración del CVC > 8 días (RMa = 17.2), ≥ 2 intervenciones quirúrgicas (RMa = 16.5) y cirugía abdominal (RMa = 2.6). CONCLUSIONES: Los RN sometidos a cirugía, principalmente aquellos con factores de riesgo, requieren vigilancia estrecha durante el posoperatorio. El CVC debe ser retirado tan pronto sea posible.

Epidemiologic Profile of the Main Bacterial Sexually Transmitted Infections During the SARS-CoV-2 Pandemic. / Comportamiento de las principales infecciones de transmisión sexual bacterianas durante la pandemia por SARS-CoV-2.

INTRODUCTION AND OBJECTIVE: The SARS-CoV-2 pandemic brought about social changes in 2020 and 2021. The aim of this study was to evaluate the epidemiologic profiles of the main sexually transmitted infections (STIs) of bacterial origin (chlamydia, gonorrhea, and syphilis) diagnosed during this period and compare them to findings from previous years. MATERIAL AND METHODS: Drawing on data from Hospital General Universitario in Valencia, Spain, we recorded the number of chlamydia, gonorrhea, and syphilis cases diagnosed monthly by multiplex PCR in 2018-2021 and the number of PCR-confirmed SARS-CoV-2 cases diagnosed monthly in 2020-2021. We also collected clinical and demographic information on all patients diagnosed with STIs during the years studied. RESULTS: The total number of STIs diagnosed increased from 570 in 2018-2019 to 664 in 2020-2021. PCR positivity rates were similar in the 2 periods, but the incidence rates were higher during the pandemic. The chronologic correlation between SARS-CoV-2 and STI positivity was negative. Mean age at diagnosis was 29.64 years (95% CI, 19.33-41.14) for chlamydia, 30.86 years (95% CI, 20.24-42.45) for gonorrhea, and 37.04 years (95% CI, 26.01-51.00) for syphilis. The number of men diagnosed with chlamydia increased by 13.85% (95% CI, 6.39-21.08; P=.0003) during the pandemic. CONCLUSIONS: We observed a negative correlation between SARS-CoV-2 infections and STIs during the pandemic and an increase in chlamydia cases among men. STI cases rose during 2020-2021, indicating that they remain a significant problem that needs to be addressed in young and adult populations.

Spanish Academy of Dermatology and Venereology (AEDV) expert recommendations for the management of sexual transmitted parasitosis. Scabies, and pediculosis pubis. / Recomendaciones de expertos de la Academia Española de Dermatología (AEDV) para el manejo de las ectoparasitosis de transmisión sexual. Escabiosis y pediculosis púbica.

Sexually transmitted infections are communicable diseases where the pathogen is transmitted through sexual contact. The Sexually Transmitted Infections Working Group of the Spanish Academy of Dermatology and Venereology (AEDV) is engaged in the drafting of documents to guide dermatologists and health care personnel who treat Spanish patients with these infections. This document analyzes the epidemiological, clinical, therapeutic, and control characteristics of 2 sexually transmitted parasitosis: scabies due to Sarcoptes scabiei var. hominis, and pubic pediculosis due to Phthirus pubis. Both parasitoses share a sort of mixed spread through sexual and community transmission regardless of the route through which the infection was initially acquired. This specific feature creates particularities in the management and control of the infestation.

[In vitro activity of delafloxacin against bacterial isolates from osteoarticular and skin infections in Buenos Aires, Argentina]. / Actividad in vitro de delafloxacina frente a microorganismos aislados de infecciones osteoarticulares y de piel y partes blandas en Buenos Aires, Argentina.

In vitro activities of delafloxacin, ciprofloxacin and levofloxacin were evaluated by epsilometric and disk diffusion methods against 181 bacterial isolates recovered from bone and skin infections. Isolates included were 84 Staphylococcus aureus (40 MRSA and 44 MSSA), 46 coagulase-negative staphylococci (CNS), 23 Klebsiella pneumoniae and 28 Pseudomonas aeruginosa. The MIC50/MIC90 (mg/l) for delafloxacin, ciprofloxacin and levofloxacin, respectively, were: MRSA, 0.004/0.064, 0.25/16 and 0.125/4; MSSA, 0.002/0.004, 0.125/0.25 and 0.125/0.25; CNS, 0.008/0.25, 0.125/>32 and 0.25/>32; K. pneumoniae, 4/>32,>32/>32 and 16/>32; P. aeruginosa, 1/>32, 0,5/>32 and 4/>32. Susceptibilities for delafloxacin, ciprofloxacin and levofloxacin, respectively, were: MRSA, 97.5%, 82.5% and 82.5%; MSSA, 97.7%, 95.5% and 95.5%; CNS, 93.5%, 63.0% and 60.9%; K. pneumoniae, 21.7%, 26.1% and 43.5%; P aeruginosa, 35.7%, 53.6% and 42.8%. The disk diffusion and epsilometric methods were concordant for evaluating in vitro susceptibility in staphylococci (categorical concordance of 98.8% for S. aureus and 91.3% for CNS).

Clinical and epidemiological features of tuberculosis isolated from critically ill patients.

Human tuberculosis is still a major world health concern. In Uruguay, contrary to the world trend, an increase in cases has been observed since 2006. Although the incidence of MDR-resistant strains is low and no cases of XDR-TB were registered, an increase in the number of patients with severe tuberculosis requiring critical care admission was observed. As a first aim, we performed the analysis of the genetic structure of strains isolated from patients with severe tuberculosis admitted to an intensive care unit. We compared these results with those corresponding to the general population observing a statistically significant increase in the Haarlem genotypes among ICU patients (53.3% vs 34.7%; p<0.05). In addition, we investigated the association of clinical outcomes with the genotype observing a major incidence of hepatic dysfunctions among patients infected with the Haarlem strain (p<0.05). The cohort presented is one of the largest studied series of critically ill patients with tuberculosis.

[Impact of an active surveillance program and infection control measures on the incidence of carbapenem-resistant gram-negative bacilli in an intensive care unit]. / Impacto de un programa de vigilancia activa y medidas de control de infecciones sobre la incidencia de bacilos gram negativos resistentes a carbapenems en una unidad de cuidados intensivos.

Hospital-acquired infections caused by carbapenem-resistant Gram-negative bacteria (CRGNB) have been increasingly reported worldwide and are associated with high rates of mortality especially in intensive care units(ICUs). Early identification through rectal surveillance cultures and implementation of infection control measures(ICM) including contact precautions, staff education on cleaning and hand hygiene may reduce the spread of these microorganisms. The aim of this work was to assess the impact of enhanced ICM on CRGNB colonization and to describe the molecular epidemiology of these bacteria in a polyvalent ICU in a tertiary level hospital. A prospective study including audits and active surveillance culture program, with molecular characterization, was conducted before and after the implementation of prevention programs and infection control measures. Microbiological screening was performed in chromogenic media; PCR targeting ß-lactamases genes (blaKPC, blaNDM, blaVIM and blaOXA-48, blaSHV and blaCTX-M), molecular typing by PFGE; and MLST in K. pneumoniae were performed. CRGNB colonization was reduced from 16.92% to 9.67% upon implementing the infection control measures. In K. pneumoniae the most frequent carbapenemase type was KPC-2 associated with SHV-2 and CTX-M-15, and was disseminated in various STs (ST17, ST13, ST2256, ST353); there was no persistence of particular clones and virulence factors showed no association with hypervirulence. IMP-1 carbapenemase predominated in A. baumannii and the PFGE analysis individualized 3 clusters, assuming that the dissemination in the ICU was clonal. The early detection of patients colonized with CRBGN by using epidemiological surveillance cultures and the implementation of prophylactic measures are key to reducing the incidence of these microorganisms.
