RESUMEN

Stevens-Johnson syndrome is an infrequent condition affecting the skin and mucous membranes, it involves cutaneous detachment with high mortality without adequate treatment. We present the case of a 40-year-old male with a history of epilepsy treated with valproic acid and lamotrigine, previously diagnosed with dengue. Evaluation showed erythematous blisters on skin and mucosa with bleeding and desquamation, covering 10% of the body surface. The patient progressed favorably with the medical care received. Stevens-Johnson syndrome should be studied in association with arboviral diseases.

RESUMEN

Multidrug resistance in bacterial strains known as superbugs is estimated to cause fatal infections worldwide. Migration and urbanization have resulted in overcrowding and inadequate sanitation, contributing to a high risk of superbug infections within and between different communities. The CRISPR-Cas system, mainly type II, has been projected as a robust tool to precisely edit drug-resistant bacterial genomes to combat antibiotic-resistant bacterial strains effectively. To entirely opt for its potential, advanced development in the CRISPR-Cas system is needed to reduce toxicity and promote efficacy in gene-editing applications. This might involve base-editing techniques used to produce point mutations. These methods employ designed Cas9 variations, such as the adenine base editor (ABE) and the cytidine base editor (CBE), to directly edit single base pairs without causing DSBs. The CBE and ABE could change a target base pair into a different one (for example, G-C to A-T or C-G to A-T). In this review, we addressed the limitations of the CRISPR/Cas system and explored strategies for circumventing these limitations by applying diverse base-editing techniques. Furthermore, we also discussed recent research showcasing the ability of base editors to eliminate drug-resistant microbes.

RESUMEN

Introduction: Surgical site infections (SSIs) can increase mortality and morbidity in patients after surgery. Antibiotic prophylaxis is an effective measure to prevent SSIs, but inappropriate prescription is frequent. The objective of the study was to determine compliance with the clinical practice guideline for antibiotic prophylaxis in the general surgery and gynecology and obstetrics wards in the city of Huánuco, Peru. Methods: An analytical cross-sectional study was carried out on all surgical interventions in the general surgery and gynecology and obstetrics services during the year 2019. Compliance was determined based on the chosen antibiotic, dose, time of administration, and duration of prophylaxis. Related factors considered were age, presence of co-morbidities, surgery performed, duration of surgery, types of procedure, anesthesia, as well as years as a surgeon and anesthesiologist. Results: A total of 557 medical records of patients with a median age of 33 years undergoing surgery were collected,. Antibiotic prophylaxis was correctly followed in all aspects in 14.6% of cases in the general surgery service and only in 5.6% of cases in the gynecology and obstetrics service. The correct duration of prophylaxis was 11.6% and 19.7% in general surgery and gynecology and obstetrics, respectively. Conclusion: Low compliance with institutional clinical practice guidelines for antibiotic prophylaxis was identified in both services. However, surgical interventions in the general surgery service presented better compliance with antibiotic prophylaxis compared to gynecology and obstetrics procedures.

RESUMEN

Introduction: Bovine brucellosis is a significant public health problem in countries with economic and zoonotic implications. Although relevant, there are no previous systematic reviews about bovine brucellosis in Latin America. Methods: We performed a systematic literature review in five data-bases to assess the seroprevalence of Brucella in cattle. A meta-analysis with a random-effects model was performed to calculate the pooled prevalence and 95% confidence intervals (95%CI). In addition, measures of heterogeneity (Cochran's Q statistic and I2 test) were reported. Results: The literature search yielded 3,403 articles, of which 65 studies were fully valid for analysis. The pooled seroprevalence for Brucella in bovine (n â€‹= â€‹46,883,177) was 4.0% (95%CI: 3.0%-5.0%; p â€‹< â€‹0.001), and Venezuela was the country with the highest prevalence (16.0%). By regions, the highest seroprevalence is in Central America and the Caribbean islands (8.0%,95%CI: 3.0%-15.0%; p â€‹< â€‹0.001, I2 â€‹= â€‹99.85). Conclusions: Some countries reported still relevant seroprevalences of bovine brucellosis, especially at the Central America and Caribbean islands. Multiple factors may influence the survival and spread of pathogens in the environment; farms located in regions bordering forest areas, in areas of difficult access to the veterinary service; extensive beef herds raised at pastures with different age and productive groups inter-mingled, and minimal concerns regarding hygiene practices and disease prevention measures. Bovine brucellosis has not been eliminated and needs to be considered with new tools for prevention and control, especially being a zoonosis.

RESUMEN

The purpose of this review is to give an up-to-date, thorough, and timely overview of monkeypox (Mpox), a severe infectious viral disease. Furthermore, this review provides an up-to-date treatment option for Mpox. The monkeypox virus (MPXV) has remained the most virulent poxvirus for humans since the elimination of smallpox approximately 41 years ago, with distribution mainly in central and west Africa. Mpox in humans is a zoonotically transferred disease that results in symptoms like those of smallpox. It had spread throughout west and central Africa when it was first diagnosed in the Republic of Congo in 1970. Mpox has become a major threat to global health security, necessitating a quick response by virologists, veterinarians, public health professionals, doctors, and researchers to create high-efficiency diagnostic tests, vaccinations, antivirals, and other infection control techniques. The emergence of epidemics outside of Africa emphasizes the disease's global significance. A better understanding of Mpox's dynamic epidemiology may be attained by increased surveillance and identification of cases.

RESUMEN

Monkeypox virus has remained the most virulent poxvirus since the elimination of smallpox approximately 41 years ago, with distribution mostly in Central and West Africa. Monkeypox (Mpox) in humans is a zoonotically transferred disease that results in a smallpox-like disease. It was first diagnosed in 1970 in the Democratic Republic of the Congo (DRC), and the disease has spread over West and Central Africa. The purpose of this review was to give an up-to-date, thorough, and timely overview on the genomic diversity and evolution of a re-emerging infectious disease. The genetic profile of Mpox may also be helpful in targeting new therapeutic options based on genes, mutations, and phylogeny. Mpox has become a major threat to global health security, necessitating a quick response by virologists, veterinarians, public health professionals, doctors, and researchers to create high-efficiency diagnostic tests, vaccinations, antivirals, and other infection control techniques. The emergence of epidemics outside of Africa emphasizes the disease's global significance. Increased monitoring and identification of Mpox cases are critical tools for obtaining a better knowledge of the ever-changing epidemiology of this disease.

RESUMEN

INTRODUCTION: Surgical site infections (SSI) can be as high in gynecology and obstetrics surgeries compared to other areas. Antimicrobial prophylaxis is an effective tool in the prevention of SSIs; however, it is often not adequately administered, so this study aimed to understand the compliance and factors associated with the use of the clinical practice guidelines for antibiotic prophylaxis in gynecological surgeries in two hospitals in the city of Huanuco, Peru. METHODS: An analytical cross-sectional study of all gynecologic surgeries performed during 2019 was performed. Compliance was determined based on the antibiotic chosen, dose, administration time, redosing, and prophylaxis duration. Age, hospital of origin, presence of comorbidities, surgery performed, as well as its duration, types of surgery, and anesthesia were considered as related factors. RESULTS: We collected 529 medical records of patients undergoing gynecological surgery with a median age of 33 years. The prophylactic antibiotic was correctly indicated in 55.5% of cases, and the dose was correct in 31.2%. Total compliance with the five variables evaluated was only 3.9%. Cefazolin was the most commonly used antibiotic. CONCLUSION: Low compliance with the institutional clinical practice guidelines for antibiotic prophylaxis was identified, showing that antimicrobial prophylaxis in the hospitals studied was inadequate.

RESUMEN

Background and Objectives. Multiple studies have evaluated the presence of bacterial contamination on cell phones in clinical settings; however, the presence and transmission of antibiotic-resistant bacteria on cell phones in the community have not been adequately elucidated. Material and Methods. A cross-sectional study was carried out to determine the presence of bacteria resistant to antibiotics on the cell phones of vendors in a Peruvian market and the associated factors. A sample of 127 vendors was obtained through stratified probabilistic sampling using a data collection form validated by experts. Cell phone samples were cultured using a standard technique, and antibiotic sensitivity was determined using the Kirby-Bauer technique. Chi-squared and Mann-Whitney U tests were used to determine factors associated with resistance in cell phone cultures. Results. Among the cell phones, 92.1% showed bacterial growth, predominantly Gram-positive bacteria (coagulase-negative staphylococci and Staphylococcus aureus), and 17% of the cultures showed resistance to at least three antibiotics evaluated. Two strains fell into the category of methicillin-resistant S. aureus, and three strains of E. coli had resistance to carbapenems. Conclusions. A short distance between customers and vendors, lack of a cell phone case, and having a cell phone with touchscreen are factors associated with antibiotic-resistant bacteria on cell phones.

RESUMEN

Introduction: Multidrug-resistant tuberculosis is a significant public health problem for which drugs are used with many adverse effects. Among the devastating consequences of these diseases, there is a wide variation in the incidence of ototoxicity and hearing loss in patients with multidrug-resistant and extremely resistant tuberculosis. Cochlear implants may be indicated in patients with unilateral/severe bilateral hearing loss with no benefit from conventional hearing aids, but their use in patients with tuberculosis is rare. Case report: We present the first case of a right unilateral cochlear implant performed on a 34-year-old Peruvian patient who presented profound sensorineural hearing loss of cochlear origin. Conclusion: Cochlear implant surgery is an essential milestone in the treatment of patients with auditory sequelae of tuberculosis treatment. Close monitoring of possible complications of tuberculosis treatment should be strengthened in countries with a high incidence of multidrug-resistant and extremely resistant tuberculosis.


Introducción: La tuberculosis multidrogorresistente es un importante problema de salud pública para el que se utilizan fármacos con múltiples efectos adversos. Entre las devastadoras consecuencias de estas enfermedades, existe una amplia variación en la incidencia de ototoxicidad y pérdida auditiva en pacientes con tuberculosis multirresistente y extremadamente resistente. Los implantes cocleares pueden estar indicados en pacientes con pérdida auditiva unilateral/bilateral severa sin beneficio de los audífonos convencionales, pero su uso en pacientes con tuberculosis es raro. Reporte de un caso: Presentamos el primer caso de implante coclear unilateral derecho realizado a un paciente peruano de 34 años que presentaba hipoacusia neurosensorial profunda de origen coclear. Conclusión: La cirugía de implante coclear es un hito fundamental en el tratamiento de los pacientes con secuelas auditivas del tratamiento de la tuberculosis. Se debe fortalecer la vigilancia estrecha de las posibles complicaciones del tratamiento de la tuberculosis en los países con una alta incidencia de tuberculosis multirresistente y extremadamente resistente.

RESUMEN

Introducción: las revistas científicas son el instrumento perfecto para comunicar resultados del proceso de investigación y transmitir el conocimiento. El comité editorial es un equipo de expertos de vital importancia en el funcionamiento de una revista científica. Sin embargo, una frecuente práctica editorial es la publicación de manuscritos en las revistas que editan. Por ello, se buscó determinar cuál es la frecuencia de la endogamia editorial en las revistas peruanas del área de la salud. Métodos: se realizó una revisión de los artículos publicados por miembros del comité editorial de 26 revistas peruanas entre el 2016 y 2019. Se realizó una evaluación de los manuscritos provenientes del comité editorial, así como un análisis de asociación entre el estado de indexación en dos bases de datos regionales; además, cómo esta influye en la frecuencia de endogamia de cada revista. Resultados: durante el periodo evaluado se publicaron 2.885 manuscritos, de los cuales 520 tenían como autores a miembros del comité editorial. El tipo de contribución más frecuente fue el artículo original. La endogamia en los años 2016 al 2018, así como un mayor porcentaje de endogamia por fascículo, fue estadísticamente mayor en las revistas pertenecientes al directorio Latindex. Conclusión: las revistas peruanas del área de la salud tienen frecuencias heterogéneas de endogamia editorial. Las revistas incluidas en el directorio Latindex presentan una mayor frecuencia de esta práctica editorial frente a las revistas que pertenecen a la base de datos SciELO-Perú.


SUMMARY Introduction: Scientific journals are the perfect instrument to communicate results of the research process and transmit knowledge. The editorial board is a team of experts of vital importance in the operation of a scientific journal, however, a frequent editorial practice is the publication of manuscripts in the journals they edit; therefore, we sought to determine the frequency of editorial inbreeding in Peruvian journals in the health area. Methods: A review of the articles published by members of the editorial board of 26 Peruvian journals between 2016 and 2019 was performed, evaluating the manuscripts from the editorial board, as well as analysis of association between the status of indexation in two regional databases and how this influences the frequency of inbreeding in each journal. Results: During the period evaluated, 2885 manuscripts were published, of which 520 had authors of the editorial board as authors. The most frequent type of contribution was the original article. Inbreeding in the years 2016 to 2018, as well as a higher percentage of inbreeding per issue, was statistically higher in the journals belonging to the Latindex directory. Conclusion: Peruvian journals in the health area have heterogeneous frequencies of editorial inbreeding. The journals included in the Latindex directory present higher frequency in editorial inbreeding, compared to journals included in the SciELO-Peru database.

RESUMEN

Visceral leishmaniasis is a neglected zoonotic disease that affects animals and humans in different tropical and subtropical regions and even beyond, with variable prevalence among infected hosts. To date, there have been no systematic reviews on human visceral leishmaniasis prevalence in Latin America. We therefore performed a systematic literature review with meta-analysis, using six databases to assess prevalence of visceral leishmaniasis in human patients in Latin American countries. Observational studies were included but analyzed separately. We performed a random-effects model meta-analysis to calculate the pooled prevalence and 95% confidence interval (95%CI). In all, 10,435 articles were retrieved for the time frame (1950-2019). After initial screening, 120 articles were selected for full-text assessment, 97 being finally included for qualitative and quantitative analyses. Overall, VL pooled prevalence was estimated at 38.8% (95% CI 33.8-43.8%), derived from 97 studies, including 44,986 individuals. Many aspects of the transmission dynamics of Leishmania and the exact burden of this parasitosis on public health remain largely unknown. Although the elimination of zoonotic VL in the Americas appears an unrealistic goal, additional efforts need to be put in place to achieve better diagnosis, treatment, and prevention of VL.

RESUMEN

Following the discovery of COVID-19 disease caused by the SARS-CoV-2 coronavirus, different studies have been carried out to recognize the stages of the disease and the methods of achieving correct diagnosis. Investigations of cases and their contacts have revealed different degrees in the symptomatology of the disease, with asymptomatic patients gaining relevance because of the controversy regarding their role in the spread of the disease. Recognition and assessment of asymptomatic patients is essential to carry out containment actions such as public health measures for affected patients and contacts. In this review, we assess the diagnostic aspects of asymptomatic patients according to the available evidence of people with COVID-19.

RESUMEN

The goal of this review was to systematize the evidence on pulmonary ultrasound (PU) use in diagnosis, monitorization or hospital discharge criteria for patients with coronavirus disease 2019 (COVID-19). Evidence on the use of PU for diagnosis and monitorization of or as hospital discharge criteria for COVID-19 patients confirmed to have COVID-19 by reverse transcription polymerase chain reaction (RT-PCR) between December 1, 2019 and July 5, 2020 was compared with evidence obtained with thoracic radiography (TR), chest computed tomography (CT) and RT-PCR. The type of study, motives for use of PU, population, type of transducer and protocol, results of PU and quantitative or qualitative correlation with TR and/or chest CT and/or RT-PCR were evaluated. A total of 28 articles comprising 418 patients were involved. The average age was 50 y (standard deviation: 25.1 y), and there were 395 adults and 23 children. One hundred forty-three were women, 13 of whom were pregnant. The most frequent result was diffuse, coalescent and confluent B-lines. The plural line was irregular, interrupted or thickened. The presence of subpleural consolidation was noduliform, lobar or multilobar. There was good qualitative correlation between TR and chest CT and a quantitative correlation with chest CT of r = 0.65 (p < 0.001). Forty-four patients were evaluated only with PU. PU is a useful tool for diagnosis and monitorization and as criteria for hospital discharge for patients with COVID-19.

RESUMEN

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic worldwide. On a daily basis the number of deaths associated with COVID-19 is rapidly increasing. The main transmission route of SARS-CoV-2 is through the air (airborne transmission). This review details the airborne transmission of SARS-CoV-2, the aerodynamics, and different modes of transmission (e.g. droplets, droplet nuclei, and aerosol particles). SARS-CoV-2 can be transmitted by an infected person during activities such as expiration, coughing, sneezing, and talking. During such activities and some medical procedures, aerosols and droplets contaminated with SARS-CoV-2 particles are formed. Depending on their sizes and the environmental conditions, such particles stay viable in the air for varying time periods and can cause infection in a susceptible host. Very few studies have been conducted to establish the mechanism or the aerodynamics of virus-loaded particles and droplets in causing infection. In this review we discuss the various forms in which SARS-CoV-2 virus particles can be transmitted in air and cause infections.
